DRYING OF FOOD GRAINS IN AN ANNULAR CIRCULATION FLUIDIZED BED

Authors: R. Parthiban

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/1-9

ABSTRACT
Drying of food materials like ragi, wheat, rice, seeds is gaining importance in recent years. Many types of driers are available in practice and fluidized bed driers are one among them. It has many advantages like (i) high degree of contact between solids and gases (ii) very high heat and mass transfer rates (iii) better temperature control (iv) absence of moving parts, rotating seals and easy maintenance (v) good mixing over other driers. In the present investigation a continuous drying of food grain – ragi has been studied. The experimental set up consists of a main body, a annular tube fixed at the centre of the main body in which the drying takes place, a disengaging section and the auxiliaries like rotameter, compressor, manometer etc. A known amount of moisture content in ragi is fed and it is dried in the annular circulation fluidized bed. The non-ideal unsteady state stirred tank reactor equation is found to fit the model. The mass transfer is predominantly controlled by gas film diffusion at lower air flow rates (4.5 to 7 cm/s) and internal diffusion at high flow rate (7 to 13 cm/s). A model was developed which is found to fit the experimental data satisfactorily.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/10-15

ABSTRACT
Electronic waste or E-waste comprises of old, end-of-life electronic appliances such as computers, laptops, TVs, DVD players, refrigerators, freezers, mobile phones, MP3 players, etc., which have been disposed of by their original users. E-waste contains many hazardous constituents that may negatively impact the environment and affect human health if not properly managed. Various organizations, bodies, and governments of many countries have adopted and/or developed the environmentally sound options and strategies for E-waste management to tackle the ever growing threat of E-waste to the environment and human health. This paper presents E-waste composition, categorization, Global and Indian E-waste scenarios, prospects of recoverable, recyclable, and hazardous materials found in the E-waste, Best Available Practices, recycling, and recovery processes followed, and their environmental and occupational hazards. Public awareness of the health and environmental threat posed by e-waste is virtually non-existent. If we continue to do nothing, these problems will become more serious. In our previous studies, cytogenetic damage effects have been found among the residents who live in the polluted area. In order to best protect public health and the environment without unfairly burdening the people of developing countries, policy makers of all developed and developing nations must be willing to fundamentally redesign the approach to e-waste management and to create awareness among them.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/16-18

ABSTRACT
Stairs consist of steps, which are quite common in most urban structures, but can even be found in archeological sites. In comparison to rugged terrain this provides a more systematic environment which could be traversed by a dynamic or static gait. There are several stair climbing designs that could be assembled with a modular robot. Custom-built climbing robots typically take the form of large legged walkers or track-based.
In this project, we are going to perform stair case climbing vehicles which are used to carry the load, moving from one place to another and used to climbing steps, perform the ascending and descending operation

Authors: M. N. Shesha Prakash, Ananthayya. M. B., Gicy M Kovoor

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/19-25

ABSTRACT
Water management is the topic duly been recognized as a priority sector in the recent days. Flow measurement has rightly acknowledged as the most important part of water management to judicious usage of all important resource water. Sharp crested weirs are relatively accurate flow measuring devices and are most commonly used devices in Open channels. Lot of research has gone through in case of flow over different shapes of normal weirs, side weirs and oblique weirs. Although sharp crested weirs are more commonly used in laboratory, they are seldom used in the field channels, as their major draw back is afflux is development resulting in Large Head loss (Coefficient of Discharge is a measure of head loss). To improve upon these drawbacks Shesha Prakash and Shivapur worked on inclined weirs. They have developed general head-discharge equation for flow through inclined notches. In the present work a generalized discharge–head-inclination model has been developed to measure flow over inclined Triangular notch. The considerable increase in the discharging capacity of the weir, with increase in inclination along the vertical plane of weir is ascertained. The established discharge-head-inclination equation through the model can provide a reasonably accurate method to predict flow over inclined trpezoidal notch. The higher discharge coefficient associated with angle  will help to improve discharge capacity and reduce afflux.

APPLICATION OF ARTIFICIAL NEURAL NETWORK FOR INTERFERENCE STUDIES OF LOW-RISE BUILDINGS

 

Authors: Narayan K*, Gairola A

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/26-40

ABSTRACT
Artificial neural network (ANN) representations are capable of developing functional relationship from discrete values of input-output quantities obtained from computational approaches or experimental results. Data obtained from wind tunnel tests for interference effects expressed by Interference Factor (IF) on gable roof building (25˚ roof slope) has been used for training the network. Training of the neural network is carried out by inputting the data sets, which consist of some selected locations of the interfering building and the corresponding values of IF for the worst design pressure coefficients (Cpq). These were determined independently for each zone of the roof. The trained network is then expected to predict the IF for Cpq for locations of interfering building not covered in the training data set. Correlation plots and contours show that most of the ANN predicted values are very close to the corresponding experimental values. 50% reduction in the experimental work can be achieved for the case studied by using the neural network modeling for interference studies in low buildings, without sacrificing any accuracy.

Authors: T. Sivakumar, G. Vijayaraghavan, A. Vimal Kumar

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/41-47

ABSTRACT
In the design and operation of filters used for the filtration of suspensions, washing and de liquoring of the formed filter cake, one is interested for reasons of operating safety, maintaining the desired quality and profitability. The main focus is to calculate the residual moisture content of the discharged filter cake and the compressor performance on parameters determined by products, adjustment and design in alignment.
A common non-disposable device used for solid-liquid phase separation for continuous flow processing is the rotary drum filtration unit. In fact, the rotary drum vacuum filter is considered to be the workhorse of the chemical process industry. In our paper we are going to bring down the moisture content of the given slurries up to a certain level. Our objective is to reduce the moisture level of whatever slurries that is taken as feed into the rotary vacuum drum filter. This will help in gain more cake formation in a single run and thus the cost of handling also becomes less and it also adds to the economy of the process.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/54-58

 

ABSTRACT
The use of vegetable oils as diesel fuel is nearly as old as diesel engine itself. The inventor of the diesel engine, Rudolf Diesel, reportedly used groundnut oil as a fuel for demonstration purpose in1900. Fuel and energy crises and the concern of society for depleting world’s fossil fuel resources initiate various sectors to look for alternative fuels. One of the most promising fuel alternative is the vegetable oils and there derivatives. Vegetable oils can be used in CI Engine by various techniques as fuel modification by esterification, diesel vegetable oil blends. The objective of this paper is to evaluate the performance and emission characteristics of pongamia oil blends with diesel in CI Engine

DESIGN AND FABRICATION OF CONTINUOUS VARIABLE TRANSMISSION IN FOUR WHEELERSC

 

Authors: M. Anand Partheeban

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/59-61

ABSTRACT
The Continuously Variable Transmission (CVT) is increasingly used in automotive applications. It has an advantage over conventional automatic transmissions, with respect to the large transmission ratio coverage and absence of comfort issues related to shifting events. This enables the engine to operate at more economic operating points. For this reason, CVT equipped cars are more economical than cars equipped with planetary gear automatic transmissions. Despite these advantages, V-belt type CVT’s still have rather large potential in transmission efficiency, Also torque capacity needs expansion. As stated before, the main disadvantages of current CVTs are transmission efficiency and torque capacity without any slippage in the belt. CVT continues to emerge as a key technology for improving the fuel efficiency of automobiles with internal combustion (IC) engines. CVTs use infinitely adjustable drive ratios instead of discrete gears to attain optimal engine performance. Since the engine always runs at the most efficient number of revolutions per minute for a given vehicle speed, CVT-equipped vehicles attain better gas mileage and acceleration than cars with traditional transmissions. CVTs are not new to the automotive world, but their torque capabilities and reliability have been limited in the past. New developments in gear reduction and manufacturing have led to ever-more-robust CVTs, which in turn allows them to be used in more diverse automotive applications. CVTs are also being developed in conjunction with hybrid electric vehicles. As CVT development continues, costs will be reduced further and performance will continue to increase, which in turn makes further development and application of CVT technology desirable.

Authors: Mrs. Nagalakshmi Sanivarapu, *Mrs.R.Kalaivani, Dr.S.R.Paranjothi

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/62-74

ABSTRACT
This paper introduces the concept of voltage stability enhancement margin is interrelated with reactive power loss. To minimize the reactive power loss, location and placement of reactive power improvement devices is a major task. The Continuation Power Flow (CPF) analysis to be used in voltage stability analysis for control the power in large systems. It starts at some base values of the system and leading to the critical point. It uses the P-V curves to find the knee point of a certain bus. The silent feature of this method is that it remains well-conditioned at the desired point, even when a single precision computation is used. The PSO method was applied to minimize the total reactive power loss in a power system network. The Newton Raphson method was used for obtaining the results and compared with evaluation methods called PSO. Particle Swarm Optimization (PSO) technique of series reactive power loss minimization is more efficient and effective and the voltage stability assessment is carried out on IEEE-14 and IEEE-30 bus system.

Authors: *Sajeed Ahmed Baig, Dr. N S Narahari

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/75-82

ABSTRACT
Health at work and healthy work environment are amongst the most valuable assets of individuals, communities and countries. In the light of rapid economic growth and industrial progress in our country, it becomes imperative that safety and health at the workplace be given its due importance. However, with stress being laid on quick profits, safety aspects are generally ignored. It is only with the increase in the number of people killed and injured at work that the significance of the problem has been realised. The costs of accidents and ill-health can be substantial to an industry. For businesses, disruption, claims for damages, loss of goodwill, and loss of confidence in management can sometimes lead to total collapse. For small companies particularly, occupational accidents can have a major financial impact. The operators in the welding industry are generally associated with high level of occupational hazards with consequent health risks. The purpose of this study was to assess the perceived occupational health hazards exposure associated with the welding process and effectiveness of OHSAS 18001 (Occupational Health and Safety Assessment Series) requirements to ensure the health and safety of workers in a welding industry located in Bangalore, India. So OHSAS 18001 is the sound solution to the ever-increasing challenge facing by the most of the organisations due to high injury and illness, lost work days, increasing occupational health and safety regulations, large citations/penalties, rising workers compensation costs, costly medical claims, worker retention and employee satisfaction.

DUST EXPLOSIONS –A MAJOR INDUSTRIAL HAZARD

 

Authors: G. Vijayaraghavan

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/83-87

ABSTRACT

Dust explosions are a major hazard in many industrial processes. In operations such as crushing and grinding, conveying, classifying and storage, an explosion may occur in the presence of combustible dusts or powders. A lot of accidental dust explosions take place in industrial plants that have powder-processing equipment. This is because more than 70% of powders processed in industry are combustible. It is essential, therefore, to accumulate much knowledge as possible on the explosion hazards of combustible powders. Some detailed studies were conducted in developed countries .A report of dust explosions in U.S.A. from 1900 – 1956 consists of information details for 75 most serious explosions out of 1125 recorded. This covered a wide range of dusts wood, food and feeds, metals, plastics, coal, paper and chemicals. In India, information pertaining dust explosions is almost non- existent solely because in most accidents that occur in India, the broad term ‘Explosion’ is used and recorded which the type of explosion goes unreported. Also, in public perception, explosions are what occur in pressurized vessels containing gases liquids, or by the operation of explosives.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/100-104

ABSTRACT
Complexes of Cu(II), Ni(II) and Co(II) with 2,3dioxo butane 2oxime4’methyl2’ furoic acid hyrazide have been synthesized. They were characterized by elemental analysis, molar conductance, magnetic measurement, IR, electronic spectral studies and thermo gravimetric analysis. Various ligand field parameters and Nephelauxetic ratio have been evaluated from out of the spectra using ligand field theory of spin allowed transitions. On the basis of above observations the complexes are proposed to be octahedral in nature. The ligand as well as metal complexes of Cu(II), Ni(II) and Co(II) have been tested for their inhibitory effects against four microorganisms viz; S.aureus, B.megaterium, B.cereus and E.coli. Antimicrobial study reveals that metal complexes are found to be more effective than ligand. Ligand and all its metal complexes show activity against E. coli only at higher concentration, but Ni(II) complexes show less activity as compared with Cu(II) and Co(II) complexes.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/105-113

ABSTRACT
This work optimizes the electro-co-deposition parameters such as current density, bath temperature and tungsten carbide (WC) loading on the morphological and mechanical properties of nickel-tungsten carbide (Ni-WC) composite coating on mild steel using nickel-sulfamate bath. The results show that the morphological properties of Ni-WC composite coating depend on electro-co-deposition parameters. The coating surface becomes coarser and thicker with increase in the current density, bath temperature and WC loading. The mechanical properties exhibit a convex variance with respect to the electro-co-deposition parameters. The optimum values of tensile strength and hardness are obtained at a current density of 3 A/dm2, a bath temperature of 55C and WC loading of 4 g/l. At the optimum condition, the microstructure, X-ray diffraction (XRD) and energy dispersive X-ray spectrometry (EDS) show uniform distribution of WC in nickel (Ni) matrix. At higher densities of coating parameters, agglomerations of WC are observed..

Authors: Manju Kulkarni ,* Harishchanddra Patil

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/128-131

ABSTRACT
The use of biometric systems is growing every day. Fingerprint scanning is the one biometric identification method available today that is mostly used. The security of fingerprint scanners has however been questioned and it has been shown that fingerprint scanners can be deceived very easily, using simple, inexpensive techniques with artificial fingerprints. This work aims to describe liveness detection technique by means of first order texture features. The “Fin key Hamster” scanner manufactured by “Nitgen Biometric solution, Korea”, having 500 dpi resolution is used for this purpose. To develop database, live fingerprint of 20 persons are taken and their corresponding gummy finger using gelatin is prepared. The images are stored in the form of template which is formed using image processing techniques. The steps include histogram equalization, binarisation, thinning, minutiae detection and false minutiae removal. Matching algorithm is developed using Euclidean distance technique. The proposed algorithm for liveness is then integrated. The results demonstrate perfect separation of live and not live for the normal conditions. False Rejection Ratio (FRR) is calculated for genuine-live users and False Acceptance Ratio (FAR) is for genuine-not live, imposter-live and imposter-not live and is found within acceptable range.

A FLASH MEMORY BETTER THAN DRAM

 

Authors: Mr. Prasad G, Mrs. Soumya KT

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/128-131

ABSTRACT
Traditional flash works by forcing charge onto a layer of metal or polycrystalline silicon called a floating gate. In terms of bits, charge on the gate represents a 1, and an absence of charge stands for a 0. A barricade of dielectrics surrounding the gate keeps the charge from escaping, even when the memory has no power. Alternatively, DRAM is much faster, keeping electrons in capacitors that charge quickly but need energy to keep their state. The NCSU flash has two floating gates instead of one. Storing all of its charge on the bottom gate, the flash can act like its old nonvolatile self. But by using the second gate and a continuous source of power, it can work more quickly, shuffling preset proportions of charge between each of the gates to represent a 1 or a 0.

Authors: Parvesh Rani, Kiran Ahuja

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/141-146

ABSTRACT
Third Generation (3G) mobile devices and services will transform wireless communications into on-line, real-time connectivity. 3G wireless technology will allow an individual to have immediate access to location-specific services that offer information on demand. 3G wireless systems such as 3G-1X, 1xEV-DO and 1xEV-DV provide support for a variety of high-speed data applications. The success of these services critically relies on the capability to ensure an adequate QoS experience to users at an affordable price. The traffic being transferred within 3G mobile networks will be composed by different information flows with various constraints on the required QoS (bit rate, delays, etc.). In this paper, we give an evaluation of the performance of 3G networks when providing access to voice and data services. In particular, we analyze through simulations a typical scenario where voice and data services affect the packet traffic in 3G system approach.

Authors: Asha. P,  K. Senthil Vadivu and N. Rajeswari

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/151-156

ABSTRACT
The food packaging industries have got a problem of deterioration of sterilized food due to the attack of micro organism. This is due to the re-contamination of the food during packaging process. The recontamination after packaging can be avoided by sterilizing the packed foods. This will help to increase the shelf life of the food by killing the micro organism. Sterilization of the packed food is possible by irradiation process. It works by disrupting the biological processes that lead to decay. In this work a new packaging material is proposed to be developed that can be used for gamma irradiation process. Gamma radiation has got good penetrating power that may disrupt the physical and chemical structure of the substrate so radiation stability is required for the packaging material. The properties of the selected material for the present work have to be analysed after the irradiation process.

Authors: Tailor Kruti.S., Patel.K.B.,Bhathawala P.H

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/157-161

ABSTRACT
This paper represents a general solution for a space and time-fractional diffusion-wave equation defined in a bounded space domain. The space- and time-fractional derivatives are desired in the caputo sense. The application of Adomain decomposition method, developed for differential equations of integer order is extended to derive a general solution of the space-and time-fractional diffusion wave equation. The solution of our model equation is calculated in the form of convergent series with easily computable contents. The example of fluid phenomenon in groundwater recharge through porous media with linear permeability is presented to show the application of the present technique. The effect of verifying the order of the time-and space-fractional derivatives on the behavior of solution has been investigated. Results show the transition from a pure diffusion process to a pure wave process and the solution continuously depends on the space-fractional derivative

Authors:Thirumalai R and Senthilkumaar J.S

 

IJAET/ VVolume II/ Issue IV/ Oct.-Dec.'2011/167-173

 

ABSTRACT
The optimum selection of machining parameters is the most important and valuable task to the process planner to achieve the low cost as well as desired quality of machined components. This paper illustrates a new approach to selection of machining parameters by using an intelligent technique. The machining parameters are optimized based on the multi-objectives which are limiting the cost and quality of the machining process. The complete methodology is illustrated by the machining experiment, which has been conducted using uncoated carbide cutting tool under dry machining condition. Using the experimental responses mathematical models are developed for objective functions as well as constraints in the multi-objective optimization. The optimized results are a set of non-dominated solutions for their multi-objective functions. In order select a single solution from the optimized solution pool the Multiple Attribute Decision Making (MADM) method is proposed, which helps to evaluate and rank the machining conditions. The higher rank solution is selected as the best solution for the machining of Inconel 718 in that respective environment.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/174-181

ABSTRACT
The supply of drinkable water is an important problem for the developing countries. Clean water is a basic human necessity, and without water the life will be impossible. The international rapid developments, the industrial growth, agriculture and population explosion all over the world have resulted in a large escalation of demand for fresh water. Tamilnadu lies in high solar radiation band and the vast solar potential can be utilized to convert saline water to potable water. The solar still is most economical way to accomplish this objective. The sun’s energy heats water to the point of evaporation. When water evaporates, the water vapor rises leaving the impurities like salts and heavy metals and condensate on the underside of the glass cover. In this context, the design modification of single basin solar still has been discussed to improve the solar still performance through increasing the production rate of distilled water. The distilled water production rate can vary with the design of the solar still, depth of water, absorbing and storage medium, vaporization technique and location. The attempts made to increase the productivity of water by using different design, absorbing materials, water depth, and heat storage medium and providing low pressure inside the still basin. They greatly improve the rate of evaporation and hence rate of condensation on the cooler surface.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/182-190

ABSTRACT
Supply Chain Management (SCM) has gained significance as one of the 21st century manufacturing paradigms for improving organizational competitiveness. Supply chain ensures improved efficiency and effectiveness of not only product transfer, but also information sharing between the complex hierarchies of all the tiers. The literature on SCM that deals with strategies and technologies for effectively managing a supply chain is quite vast. In recent years, organizational performance measurement (PM) and metrics have received much attention from researchers and practitioners. In this paper the performance is evaluated on five important links of the supply chain management system like inbound logistics, manufacturing, outbound logistics, marketing and after sales service. This paper describes a framework for performance measurements in supply chains. In addition, a multi-attribute decision-making technique, an analytic hierarchy process (AHP), is used to make decision about weak link based on the priority of performance measures. On the basis of questionnaire collected for each level from Indian industries. The mean rating (both level) is utilized, as the input data to compute the pairwise comparisons of criteria.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/191-195

ABSTRACT
The use of piled raft foundations has become more popular in recent years, as the combined action of the raft and the piles can increase the bearing capacity, reduce settlement, and the piles can be arranged so as to reduce differential deflection in the raft. Piled raft foundation is a new concept in which the total load coming from the superstructure is partly shared by the raft through contact with soil and the remaining load is shared by piles through skin friction. A piled raft foundation is economical compared to the pile foundation. Because piles do not have to penetrate the full depth of clay layer but it can be terminated at higher elevations. Such piled raft foundation undergoes more settlement than the pile foundation and less settlement than the raft foundation. In this paper the author has study different parameters like size of the raft, thickness of the raft, diameter of the piles, length of piles, configuration of piles stiffness of raft and piles etc., which affect the behaviour of piled raft foundation. And its interdependency is also reviewed. This study is useful to decide the various parameters required in the design of piled raft foundation.

Authors: AKHIL KHARE, AMOL N. JADHAV

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/196-201

ABSTRACT
The relations between verbs and their arguments in the same sentence have the potential for analyzing terms within a sentence. The information about who is doing what to whom clarifies the contribution of each term in a sentence to the meaning of the main topic of that sentence. This work bridges the gap between natural language processing and text mining disciplines.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/202-206

ABSTRACT
In this paper, optimal design of three phase squirrel cage induction motor to improve efficiency and power factor and to reduce total loss for variable load application is proposed. It has compared conventional and optimally designed same rating of 10hp (7.5kW) motor. The motor is designed and optimization using Genetic Algorithm and the simulation results are presented. The Genetic Algorithm is used for optimization and five objective functions namely Stator Copper Loss, Rotor Copper Loss, Stator Iron Losses, Efficiency, and Power Factor are considered. The importance of this work is highlighted by the recent concerns about the need to achieve energy savings in the industry and in the territory sectors. The motor design procedure consists of a system of non-linear equations, which imposes induction motor characteristics and motor performance. This is very useful to optimize the power factor, losses and efficiency of the induction motors.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/207-210

ABSTRACT
Image segmentation is one of the most important techniques used for image processing based applications and has a vital impact on the overall performance of the developed systems. The goal of image segmentation is to cluster pixels into regions corresponding to individual surfaces, objects, or natural parts of objects. More precisely, image segmentation is the process of assigning a label to every pixel in an image such that pixels with the same label share certain visual characteristics. In this paper, we have introduced two varieties of image segmentation using clustering algorithms – the K-means clustering algorithm and the Global K-means (GK-means) clustering algorithm. The purpose is to give a brief explanation of the basic structure of these methods. Both methods are considered for their speed, complexity, and utility. Implementation of each algorithm is then discussed. Finally, the experimental results of each algorithm are presented. We have chosen the MATLAB programming language for the implementation mainly because of the increasing popularity of this language, and there is an extensive quantity of in-built simple applications in this language.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/218-225

ABSTRACT
The Power and Bandwidth are the scarcer resources in wireless communication system. The advancement in cellular communication is witnessing the growing number of users and applications. The challenge lies in accommodating this growing demand, fit into the available bandwidth. An optimum utilization of limited bandwidth demands for a channel allocation scheme where a channel can be allocated to incoming call to meet the service request. The problem of finding a conflict free channel allocation with minimum interference and minimum channel span is NP hard.
To address this issue, this paper presents dynamic channel allocation using Particle Swarm Optimization (PSO) technique. The velocity update function is modified by introducing dynamic varying inertia. The system is simulated and the operation is performed on well known benchmark problems. The experimentation is done for various population sizes and its effect is observed.
The obtained result show that an optimum solution for channel selection is obtained at a faster rate as compared to other algorithms and lower values of call rejection ratio is also observed. This improves the efficiency of system for call admission and ultimately the capacity of the system is improved.

ABSTRACT
Semiconducting oxides SnO2, TiO2, In2O3 and Al2O3 were mixed in different stiochiometry in mol % for the study. The sensors are prepared in the form of thick films prepared by screen-printing technique on chemically clean optically plane glass substrate. From the FTIR spectra it is clear that the surfactant incorporated in the samples. All of the devices tested and finally concluded that the A3 (80 TiO2-10 In2O3-10 Al2O3) exhibited high sensitivity and fast response time to NH3 at room temperature. In all the samples the sensitivity increases by increasing concentration of NH3 gas in ppm. The resistance of thick films decreases by increasing concentration of NH3 gas in ppm at room temperatures due to surface oxygen vacancies of SnO2/TiO2 act as electron donors.

Authors: Chandra Arunesh* Chandna Pankaj

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/231-238

ABSTRACT
The purpose of this paper is to focus on certain important aspects of screwdriver use in occupational work situations, with an emphasis on comfort/discomfort in using screwdriver according to users. Descriptors of comfort/discomfort in using hand tools were collected from literature and interviews. Six comfort factors could be distinguished (functionality, posture and muscles, irritation and pain of hand and fingers, irritation of hand surface, handle characteristics, aesthetics). These six factors can be classified into three meaningful groups: functionality, physical interaction and appearance. It is concluded that functionality and physical interaction are the most important factors of comfort in using screwdriver. Thus the designers can use to address the appropriate comfort descriptors in the hand tool design process; an attempt is made to illustrate the relevance of anthropometric data in the design of handle of hand tools (screwdriver) using ergonomic principles. The modified ergonomic designed handle of screwdriver will allow higher working efficiency and more torque than conventional handle.

Authors: *Ms Mirajkar Pradnya P., Sachin D. Ruikar

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/242-250

ABSTRACT
The fusion of images is the process of combining two or more images into a single image retaining important features from each. Fusion is an important technique within many disparate fields such as remote sensing, robotics and medical applications. The result of image fusion is a single image which is more suitable for human and machine perception or further image-processing tasks. The image fusion algorithm based on wavelet transform is proposed to improve the geometric resolution of the images, in which two images to be processed are firstly decomposed into sub images and then the information is performed using these images under the certain criteria and finally these sub images are reconstructed into result image with plentiful information. In this paper, we focus on the fusion of images from different sources using multi resolution wavelet transforms. Based on reviews of popular image fusion techniques used in data analysis, different pixel based methods and using masking is experimented. This architecture with a hybrid algorithm is proposed which applies pixel based maximum selection rule to low frequency approximations and filter mask based fusion to high frequency details of wavelet decomposition. The key feature of hybrid architecture is the combination of advantages of pixel and masking in a single image which can help the development of sophisticated algorithms enhancing the edges and structural details. A standalone executable application developed using Matlab Compiler.

ABSTRACT
As the world is advancing forth technically in the field of space research, missile and nuclear industry; very complicated and precise components having some special requirements are demanded by these industries. The conventional methods, in spite of recent advancements are inadequate to machine such materials from stand point of accuracy, precision and economic production. The metal like hastalloy, Nitra alloy, nimonics and many harder to machine material are such that they can’t be machined by conventional methods but require some special techniques. Abrasive jet machine (AJM) removes material through the action of focused beam of abrasive laden gas. Micro – abrasive particles are propelled by an inert gas of velocity. When directed at a work piece, the resulting erosion can be used for cutting, etching, drilling, polishing and cleaning. In this paper testing and analyze various process parameters of abrasive jet machining is presented

A FLASH MEMORY BETTER THAN DRAM

 

Authors: Mr. Prasad G, Mrs. Soumya KT

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/267-268

ABSTRACT
Traditional flash works by forcing charge onto a layer of metal or polycrystalline silicon called a floating gate. In terms of bits, charge on the gate represents a 1, and an absence of charge stands for a 0. A barricade of dielectrics surrounding the gate keeps the charge from escaping, even when the memory has no power. Alternatively, DRAM is much faster, keeping electrons in capacitors that charge quickly but need energy to keep their state. The NCSU flash has two floating gates instead of one. Storing all of its charge on the bottom gate, the flash can act like its old nonvolatile self. But by using the second gate and a continuous source of power, it can work more quickly, shuffling preset proportions of charge between each of the gates to represent a 1 or a 0.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/278-283

ABSTRACT
This paper presents the investigation of an ideal configuration of the UCAV structure by means of strength, stiffness and aircraft stability. As a basic approach the wing is geometrically modeled by focusing on the spar and rib locations and as a second step the wing is analyzed by changing the sweepback angle to 45 and 60 degrees so as to identify the efficient Planform shape within the selected planforms. The different wing configurations are compared by conducting the static aero-elastic and flutter analysis using MSC/NASTRAN analysis tool. The geometric and finite element models were developed by the MSC/PATRAN and the analyses were carried out at 5g maneuver for Mach number 0.8 for the symmetric model of the UCAV. The comparison of the results obtained showed that the wing with spar located at 30% from leading edge has given moderate results in terms of the static stresses, stability and natural frequencies. Furthermore, it is concluded that the wing with smaller sweepback angles have indicated significant effects.

Authors: Doiphode G. S., Patodi S. C.*

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/289-295

ABSTRACT
Solution to fiber reinforced composite plate problem under different types of loading and boundary conditions is attempted using Integrated Force Method (IFM). Internal moments developed due to external loading are calculated by imposing simultaneously the equilibrium equations and compatibility conditions. Various closed form matrices are developed by discretizing the potential strain energy for a four noded rectangular element having 9 force and 12 displacement degrees of freedom; which is named as RECT_9F_12D element. Using symmetry, the influence of aspect ratio on internal moments and deflections is studied. Matlab is exploited for plotting the moment contours and deflected shape of transversely loaded plates. The numerical results obtained for twelve Glass Fiber Reinforced Plastic (GFRP) plate problems are compared with the available small deflection theory results to validate the proposed formulation and its computer implementation; a good agreement is found.

Authors: Dr. S.K. Dubey , P.D. Sangamnerkar

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/296-301

ABSTRACT
The main objective of this study is to understand different irregularity and torsional response due to plan and vertical irregularity, and to analyze “T”-shaped building while earthquake forces acts and to calculate additional shear due to torsion in the columns. Additional shear due to torsional moments needs to be considered because; this increase in shear forces causes columns to collapse. So in design procedures this additional shear must be taken into account.

IMAGE INPAINTING USING WAVELET TRANSFORM

 

Authors: *Vaibhav V Nalawade, Sachin D Ruikar

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/302-307

ABSTRACT
The filling in of missing region in an image is known as image inpainting. Image inpainting or completion is a technique to restore a damaged image. Recently various approaches have been proposed. Wavelet transform has been used for various image analysis problems due to its nice multi-resolution properties and decoupling characteristics. We propose to utilize the advantages of wavelet transforms for image inpainting. Unlike other inpainting algorithms, we can expect better global structure estimation of a damaged region in addition to shape and texture properties. Inpainting is the art of modifying an image in a form that is not detectable by an ordinary observer. There are numerous and different approaches to tackle the inpainting problem. This paper putforths the overview of the work done in the field of image inpainting. The inpainting technique can be classified into two categories: (1) texture oriented and (2) structure oriented. Both the technique have their advantages and disadvantages. The wavelet based algorithm combines the advantages of both of these approaches. Wavelet transform has been used for various image analysis problems due to its nice multi-resolution properties and decoupling characteristics [1]. This algorithm proposes to utilize the advantages of wavelet transforms for image inpainting. Exemplar based structure synthesis contains the essential process to replicate both texture and structure [9].

Authors: Shah Manit Vijay*

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/344-348

ABSTRACT
The paper presents the development of a fuzzy PID Controller for a multi input and multi output paper machine system. The job of paper machine is to transform slurry of water and wood cellulose fibers into a saleable sheet of paper as efficiently as possible. The controller used in this process is PID controller because of the simple structure and robust performance. PID controllers however have some disadvantages, one of which is they are originally meant for single input and single output systems. In order to overcome these disadvantages, a fuzzy system is developed. Moreover, a combination of fuzzy controller with PI and PID controllers is developed to obtain better results. Even though fuzzy system is giving better performance than the conventional controller, the optimal performance is not found. The optimal performance of the fuzzy system Multi Input Multi Output model, PID Controllers, Fuzzy logic controllers, Genetic Algorithm is achieved by designing the fuzzy member ship functions by using genetic algorithms.

Authors: Vivek Sharma

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/353-357

ABSTRACT
This study was undertaken to evaluate the mineral and organic chemical constituents of fish Labeo Pangusia.First the mineral constituents Na, Ca, Mg, P, CO2 and F were determined before U.V. irradiation. Thereafter same minerals i.e. after 1 hour, 10 hours and 20 hours Irradiation, organic constituents were determined .All mineral constituents remain unchanged as a result of irradiation. Total nitrogen, Crude fat and Crude protein show continuous decrease with increase in the time of exposure i.e. Percentage decrease after 20 hour exposure is 2.84, 6.78 & 2.971 respectively. Likewise Amino acids also exhibited decreases in their content, decrease being maximum in the glycine content after 20 hours exposure. The reason for the decrease is the C-C bond cleavage with the formation of free radicals and evolution of ammonia. Exposure reduced the weight of the scale powder.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/358-363

ABSTRACT
Environmental pollution is one of the most serious problems facing humanity and other life forms on our planet today. Industrial waste is very dangerous amongst all other wastes. So to discharge this industrial waste safely, it is recommended to make it useful in making some products. In this project Zeolite Based Spent Catalyst (ZBSC) is used to partially replace cement in concrete. ZBSC is the waste product from petroleum industry. Here the aim of study is to obtain the optimum percentage of cement that can be replaced by ZBSC and to find the optimum design mix at which the strength of concrete is maximum at minimum cost. Initially trials were made on cement mortar and from the results it was decided to replace 25% and 35% cement by ZBSC in concrete. Dose of super-plasticizer was decided from trial mixes to maintain the medium workability in all the mixes. Compressive, flexure and spilt tensile strength were measured at different age of concrete. Long term strength at the age of 112 days curing was measured and results are encouraging. Initially the strength are slightly less but long term strength i.e. after 90 days is very nearer to the strength of concrete without addition of waste.

Authors: Souvik Ganguli*

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/381-383

ABSTRACT
This paper addresses a new split source type converter topology for switched reluctance motor drives. This converter topology consists of 2 DC link capacitors, 6 switches and 6 diodes with 2 switches and 2 diodes adding to a conventional split source converter to drive an 8/6 pole SRM. The main advantage of this converter is fast suppression of the tail current in the phase-winding, hence, resulting in minimization of negative torque using doubly boosted voltage in the demagnetizing mode. Finally, the characteristics of this converter are compared with that of the asymmetric bridge converter that is widely used for switched reluctance motor drives. From the results obtained it found that this converter has shown higher efficiency and more output power than an asymmetric bridge converter in the heavy load condition and in the high-speed operation.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/390-392

ABSTRACT
This paper represents how mobile message can be send by storing into files and configure with message service of any mobile operator. The concept is to send the message with database like Mail Merge works for MS-Word. In the message enter the simple text and the name of the field in between<< columnname>> symbols. The field of the table will come from the database file which will be provided by DSN less connection and the path will be located from the storage card or phone memory of particular mobile, Mobile scripting language will take care of the entire programming, as it supports DSN-less connection. In the background the script will take of database connection. The output of the message will be stored into a file and then it will be send to the different mobile numbers with different records. By configuring with SMS service, we can easily send all the messages to different mobile numbers with different contents. New concept in the area of SMS Service by mobile programming for sending messages. manage SMS by putting restrictions for particular date on a mobile due to SMS operator for sending bulk mobile messages. Instead of sending emails using mail merge now we can send messages using Message Merge.

Authors: Ankush Kumar, Sumit Chakraborty, Ankit Kumar, Saad Parvez & Dr. Marouf Wani

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/393-395

ABSTRACT
The aim of the work is to propose measures and device methods to reduce and prevent dust at Coal Handling plant (CHP) of a coal fired thermal power plant. This paper discusses qualitative methods for preventing dust including design of a wet centrifugal dust collector. Since wet dust suppression system uses optimum amount of water for suppressing dust, therefore use of dust collector which discharges dust in the form of slurry is very elegant approach to control dust at large scale. Every thermal power plant is equipped of a large CHP where coal is handled. Such plants consume large quantity of water in order to suppress dust properly which is undesirable. Therefore use of dust collector units at particular places of CHP plant where dust particles are airborne is highly recommended, since it discharges dust in the form of slurry.

Authors: Amolkumar N.Jadhav, Ashish Manwatkar, Deepak Dharrao

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/398-400

 

ABSTRACT
Most of the common techniques in text mining are based on the statistical analysis of a term, either word or phrase. Statistical analysis of a term frequency captures the importance of the term within a document only. However, two terms can have the same frequency in their documents, but one term contributes more to the meaning of its sentences than the other term. Thus, the underlying text mining model should indicate terms that capture the semantics of text. In this case, the mining model can capture terms
that present the concepts of the sentence, which leads to discovery of the topic of the document. A new concept-based mining model that analyzes terms on the sentence, document, and corpus levels is introduced. The concept-based mining model can effectively discriminate between non-important terms with respect to sentence semantics and terms which hold the concepts that represent the sentence meaning. The proposed mining model consists of sentence-based concept analysis, document-based concept analysis, corpus-based concept-analysis, and concept-based similarity measure. The term which contributes to the sentence semantics is analyzed on the sentence, document, and corpus levels rather than the traditional analysis of the document only. The proposed model can efficiently find significant matching concepts between documents, according to the semantics of their sentences. The similarity between documents is calculated based on a new concept-based similarity measure. The proposed similarity measure takes full advantage of using the concept analysis measures on the sentence, document, and corpus levels in calculating the similarity between documents. Large sets of experiments using the proposed concept-based mining model on different data sets in text clustering are conducted. The experiments demonstrate extensive comparison between the concepts based analysis and the traditional analysis. Experimental results demonstrate the substantial enhancement of the clustering quality using the sentence-based, document-based, corpus-based, and combined approach concept analysis.

ABSTRACT
Coimbatore is a fast growing city, Manchester of Tamil Nadu, India. In Coimbatore Industry effluents and wastes being discharged randomly on soil, river, lake and road side without any treatment. They pollute productive soil, natural water system as well as ground water. Assessment of heavy metal content in soil and wetland from various localities of Coimbatore, Tamil Nadu was undertaken. Heavy metal pollution generally a non-stationary variable, the technique of universal kriging is applied in preference to ordinary kriging as the interpolation method.
Topsoil samples (0-20 cm) were taken at various locations with reference to latitude and longitude. The concentration of heavy metal As, Hg, and Cd were analyzed in the Atomic Absorption spectrometer. Universal Kriging model was developed with suitable empirical semivariogram model. The model having the least error was selected by comparing the observed water-table values with the values predicted by empirical semivariogram models. It was determined that the presence of As is high at As. Presence of Hg is high in kuruchi. Presence of Cd is high at Sanganur road were because of electroplating industries. The aim of this analysis is to investigate the level, causes of heavy metal contamination in soil and prediction of heavy metal at various locations in the vicinity of industries and around Coimbatore city.

Authors: Shweta Jain*, Vikas Gupta and Divya Jain

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/427-430

 

ABSTRACT
Multi-carrier modulation is an attractive technique for fourth generation wireless communication. Orthogonal Frequency Division Multiplexing (OFDM) is an efficient method of data transmission for high speed communication systems. However, the main drawback of OFDM system is that, it exhibits high Peak to Average Power Ratio (PAPR) of the transmitted signals. OFDM consist of large number of independent subcarriers, as a result of which, the amplitude of such a signal can have high peak values. The Selected Mapping (SLM) and turbo coding is one of the promising PAPR reduction techniques for OFDM. In this paper, the issue of PAPR in OFDM is discussed. Two new methods are proposed to reduce the PAPR. First method is carried out by selecting mapping, the input sequence properly using a Hamming code and second method is turbo code using interleavers encoder. These two methods provide better result.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/431-434

 

ABSTRACT
At places where clay deposit are of larger thickness, and if it possesses sufficient strength (qu>100 KN/m2), raft foundation can be employed. If the foundation has a very poor strength (qu=0 to 25 KN/m2), purely pile foundation will prove to be a better option. But if the clay deposit has an intermediate strength (qu=50 to 100 KN/m2), the only option available is piled-raft foundation which is economical since the piles help in reducing settlements and the raft provides an ample bearing capacity as well as resistance to differential settlements. Thus piled-raft is a good alternative at places where more total settlements are permissible for the structure along with a considerable bearing capacity. This review paper aims with an objective to summarize the analytical approaches for the analysis of combined piled-raft systems which is an emerging concept specifically when foundations are to be designed for clay deposits.

RAPID PROTOTYPING/RAPID TOOLING – A OVER VIEW AND ITS APPLICATIONS IN ORTHOPAEDICS

 

Authors: Mr. D. CHANDRAMOHAN,  Dr. K. MARIMUTHU

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/435-448

 

ABSTRACT
This research focuses a new method of using data obtained from CT images combined with digital CAD and rapid prototyping model for the surgical planning of difficult corrective and this new application enables the surgeon to choose the proper configuration and location of internal fixation of plate on humerus bone in the field of orthopaedics. This paper presents the procedure for making model of humerus bone using rapid prototyping technologies [RPT]. Production of prototypes for medical modeling (orthopaedics) in general can be classified into two broad categories based on manufacturing process route and type of data available, i.e. designed data and scanned/digitized data. Designed data is data that is created according to a person's idea on computer aided design (CAD) system. For this type of data, the designer has total control to modify, adjust and manipulate his design ideas to serve the functional purpose of his design. Producing models with this type of data is very straightforward and no further data treatment is required. CAD solid model can be directly converted to STL format for use in subsequent rapid prototyping process. For this type of data, the user has limited capability to modify and manipulate the geometry and further processing is required before they can be readily used by rapid prototyping system. For example, further data treatment is needed for Scanned data from computed tomography (CT) and magnatic resonance imaging (MRI) scanners which capture soft and hard tissue information based on density threshold value. The undesired soft tissue data is removed before it is sent to rapid prototyping machine for fabrication. This procedure can be a daunting task for complex structure and one has to repeat the procedure many times until satisfactory result is achieved. There are a number of commercial software’s such as MIMICS, and Go-build which translate this data to the format required by RP systems. Also ,this paper describes rapid tooling methods.

AN OVERVIEW OF BIOREACTOR DESIGN FOR PROTEIN AND ENZYMES ENRICHEMENT OF AGRICULTURAL RESIDUES BY SOLID STATE FERMENTATION

 

Authors: Mosleh M. Manfe*, S. J. Attar, Niraj S.Topare

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/455-460

 

ABSTRACT
In this review article we discuses about bioreactor designs and their use for protein production under solid state fermentation (SSF) conditions using various agricultural by-products. The advantages and disadvantages of various bioreactors and their potential for scale-up are described. SSF is proposed as a suitable low-tech strategy for protein enrichment for animal feed by converting a previously low value substance into a more nutritionally valuable one. The use of various substrates and microorganisms for protein enrichment are also listed. Solid-state fermentation has emerged as a potential technology for the production of microbial products such as feed, fuel, food, industrial chemicals and pharmaceutical products. Its application in bioprocesses such as bioleaching, bio-beneficiation, bio-remediation, bio-pulping, etc. has offered several advantages. Utilization of agro-industrial residues as substrates in SSF processes provides an alternative avenue and value-addition to these otherwise under- or non-utilized residues. Today with better understanding of biochemical engineering aspects, particularly on mathematical modeling and design of bioreactors (fermenters), it is possible to scale up SSF processes and some designs have been developed for commercialization. It is hoped that with continuity in current trends, SSF technology would be well developed at par with submerged fermentation technology in times to come.

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/461-464

 

ABSTRACT
In present age of competition and economic turbulence, all types of organizations are striving hard to control costs, maintain high levels of productivity, meet changing expectations of the customers and attain quality bench marks to sustain in the market. In this context, Six Sigma is a powerful world class improvement business strategy that enables companies to use simple but powerful statistical methods to define, measure, analyze, improve and control (DMAIC) processes for achieving operational excellence. From the literature survey, it is found that most of the Six Sigma work has been carried out in big manufacturing industries only and there is a definite scope of improvement in process industries, small and medium manufacturing industries and in service sector through Six Sigma application. The literature review on Six Sigma also suggests that the application of Six Sigma in the areas other than the big manufacturing industries has been rare and inconsistent, so there is a definite scope of opportunity to apply Six Sigma to diverse organizations in small sector and analyze the results. Literature also provides not much documented evidence of Six Sigma implementation in small industries which has a significant role in the Indian economy. On seeing the tremendous financial gains reaped through Six Sigma programs in big manufacturing sector, it is urgently required to replicate this strategy in small scale sector too. The contribution of small scale industries to the Indian economy cannot be ignored as this sector is strategically placed in the industrial population of the country and in the global economy as a whole. The increasing demand for high-quality products and highly capable business processes by large organizations has left no choice on the SMEs to consider the introduction of Six Sigma business strategy.

Authors: Vikash Choudhary, Satendar Pal Singh, Vikash Kumar

 

IJAET/ Volume II/ Issue IV/ Oct.-Dec.'2011/465-469

 

ABSTRACT
The compensating signal is learned prior to normal operation, in a self-comissioning run, but the neurofuzzy methodology is also suitable for on-line self learning implementation, for continuous improvement of the compensating signal. There are fuzzy inference systems for which the connection of premises by means of t-norms is not adequate. Compensating aggregation operators are required. The paper shows how to extract this kind of fuzzy if-then rules from numerical data of behaviour with the help of neural networks. Furthermore the method allows to extract fuzzy if-then rules from any neural network using activation functions from a given class (which includes the logistic function).

ABSTRACT
The strength characteristics of any masonry depend on the strength and elasticity parameters of masonry units, mortar and their interactive behavior. Hollow concrete block masonry has several advantages compared to burnt brick masonry. Because of its uniform size and shape, concrete block masonry saves mortar consumption in the bed joint and plastering. In view of high energy consumption and unorganized method of production of burnt brick, the cost of fuel for brick kiln is controlled by its supply and demand in the local market. Whereas in the process of concrete blocks production the major cost component is cement whose price is usually insensitive to supply and demand in the local market. Hence unlike burnt bricks, the unit cost of concrete blocks is somewhat stable. In most of the cases the production of concrete blocks is mechanized thus it is possible to meet the requirement of the ever increasing demand in the urban construction activity with consistent quality blocks. Large quantities of granite fines are generated from the granite industry. As a result, solid waste management including the granite fines has become one of the major environmental concerns in the world. With the increasing awareness about the environment, scarcity of land-fill space and due to its ever increasing cost, waste materials and by product utilization like granite fines has become an alternative to disposal. In this work we have highlighted some aspects concerning the use of granite fines in various proportions in the manufacture of hollow concrete blocks. In this study high performance Hollow blocks are manufactured of size 400mm x 200mm x 200mm utilizing granite fines as an additive. These blocks were tested for routine tests as per IS-2185 (part-I & part II) of Bureau of Indian standards, such as compressive strength, Bulk density and water absorption. Based on the results presented in this paper, it can be concluded that High Strength and High performance Hollow Concrete Blocks can be manufactured by the use of Granite fines as an additive.

Authors: Akhil Khare, Kendre Pallavi H.

 

IJAET/ Volume II/ Issue IV/Oct-Dec, 2011/509-513

 

ABSTRACT
Accurate prediction of fault prone modules in software development process enables effective discovery and identification of the defects. Specific models and algorithms referred to identify the fault proneness in a system. Such prediction models serve the large-scale systems, where verification experts need to focus on development process. The ability of software quality models to accurately identify critical components allows for the application of focused verification activities ranging from manual inspection to automated formal analysis methods. Software quality models, thus, help ensure the reliability of the delivered products. The basic hypothesis of software quality prediction is that a module currently under development is fault prone if a module with the similar product or process metrics in an earlier project (or release) developed in the same environment was fault prone. Therefore, the information available early is directly proportional.

Authors: Akhil Khare, Ahmed Khodair

 

IJAET/ Volume II/ Issue IV/Oct-Dec, 2011/514-517

 

ABSTRACT
A number of statistical techniques, principally Agglomerative Hierarchical Clustering (AHC) analysis, Byte Code Instrumentation are used to facilitate the identification of such objects. Dynamic coupling indicates the strength of association established by a connection from one software module to another at runtime. Despite the rich body of research in the field of software measurement, dynamic coupling measurement for Aspect Oriented software is still missing. A dynamic coupling measurement framework for AspectJ[10] programs is presented. The framework consists of a suite of measures for both method-level and class-level coupling relations. This paper also presents a new approach towards static analysis, in particular class analysis to the computation of dynamic coupling measures and is designed to work on incomplete programs.

Authors: H K Sawant, Shah Ashwini V.

 

IJAET/ Volume II/ Issue IV/Oct-Dec, 2011/518-522

 

ABSTRACT
Clustering is a process of forming groups (clusters) of similar objects from a given set of inputs. Good clusters have the characteristic that objects belonging to the same cluster are "similar" to each other, while objects from two different clusters are "dissimilar". The idea of clustering originates from statistics where it was applied to numerical data. However, computer science and data mining in particular, extended the notion to other types of data such as text or multimedia.

BIOSORPTION OF CHROMIUM (Cr VI) FROM AQUEOUS SOLUTIONS USING COCONUT HUSK

 

Authors: Prachee Karde, Vivekanand Rathod and P N Dange

 

IJAET/ Volume II/ Issue IV/Oct-Dec, 2011/528-533

 

ABSTRACT
Biosorption of Cr (VI), from aqueous solutions, using coconut coir was investigated. Equilibrium studies were performed in batch wise manner at various biomass loads, pH values and time with fixed initial concentration. Biosorption was ostensibly fast initially, but gradually became sluggish owing to penetration of metal into the interior of the bio-sorbent particles. The data showed that optimum pH for efficient biosorption of chromium (VI) by coconut husk was 4.6. The maximum adsorption capacity showed that the coconut husk had a capacity of 40 mg/gm for Cr (VI). To identify a suitable kinetic equation; detailed analysis has been conducted using first order and pseudo second order kinetic models. Predictions based on the pseudo second order rate expression were found satisfactory in accordance with experimental data.
