ABSTRACT
Artificial neural networks (ANNs) and Response Surface Methodology (RSM) are often used in manufacturing field for modeling complex relationships which are difficult to describe with physical models. However, determining suitable training and architectural parameters of an ANN still remains a difficult task. These parameters are typically determined by trial and error procedure, where a large number of ANN models are developed and compared to one another. This paper aims to apply Taguchi method for the optimization of ANN model. A case study of modeling resultant Cutting Force, Surface Finish and Cutting Temperature in turning process is used to demonstrate implementation of this approach. Genetic Algorithms are used to optimize the performance parameter obtained from ANN model. This paper reviews both of these (ANN and RSM) methodologies and suggests their appropriate use for a given case. Two methodologies are compared for their modeling abilities, prediction and optimization. The predictive and generalization abilities of both Taguchi optimized ANN and RSM are compared using separate dataset of 80 and 20 respectively, carried out for Waspaloy while turning on retrofitted VDF lathe. It is found that the choice of either of the methodology depends upon the complexity of the relationship of process and performance parameter, the cost and sensitivity required..

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/39-41

  Authors: Dattatray B. Gavade, Prof. Satej S.Kelkar
 

ABSTRACT
Design of suspension systems for Heavy Trucks is always challenging due to the heavy loads the system is exposed to and the long life requirements for the total system [1].Topology optimization is used at the concept level of the design process to arrive at a conceptual design proposal that is then fine-tuned for performance and manufacturability. This replaces time consuming and costly design iterations and hence reduces design development time and overall cost while improving design performance. A mathematical approach that optimizes material layout within a given design space, and for a given set of loads and boundary conditions such that the resulting structure meets a prescribed set of performance targets. Using topology optimization, engineers can find the best concept design that meets the design requirements. Application of topology optimization has been done with finite element methods..

EVALUATING AERODYNAMIC BEAD SHAPE IN A HEAT EXCHANGER TUBE FOR IMPROVEMENT IN THE RATE OF HEAT TRANSFER FOR THE SYSTEM

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/47-49

  Authors: Rohit R. Jadhao, Shylesha Channapattanna, Swapnil S. Kulkarni
 

ABSTRACT
The challenges posed to the effort of enhancing the rate of heat transfer includes drop in pressure at the delivery end of the tube. Generating higher turbulence improves the rate of heat transfer but at the cost of the drop in pressure in the system. This leads to higher power consumption for the same amount of heat transfer. The study undertaken for this dissertation work aims to introduce aero-dynamics in the construction of the heat exchanger that would streamline the flow of air through the channel and eventually reduce the pressure drop in the system. For deployment of CFD methodology, ANSYS Fluent is proposed as a software tool while validation shall be pursued using physical experimentation either for the benchmark geometry or the proposed solution based on feasibility of development of prototype for this work.

 

DOMAINS OF FLAMMABILITY AND THERMAL IGNITABILTY OF ORGANIC DUSTS FOR EXPLOSION HAZARD ANALYSIS AND SAFETY

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/50-56

  Authors: Manju Mittal
 

ABSTRACT
This paper presents the experimental data for particle size dependence of minimum explosible concentration (MEC) determined in CSIR-CBRI 20-L Sphere at ambient conditions and minimum ignition temperature (MIT) of dust-air cloud measured in Godbert-Greenwald (G-G) furnace for some organic dusts-coal A (volatiles-27.19%), coal B (volatiles-19.69%), maize starch, wheat flour and sugar in a specific format- the graphs showing domains of flammability and thermal ignitability. For all the dusts MEC became insensitive to particle size below some characteristic size and increased significantly above those characteristic sizes until a critical size was reached, above which the dust was non-flammable for any concentration at ambient temperature and pressure. The MIT displays behaviour similar to that of MEC, except that heating of the mixture to the elevated temperature required for each thermal ignitability studies markedly increases the flammability range. At those elevated initial temperatures, the characteristic sizes are shifted to larger diameters and no critical sizes were observed for some of the MIT measurements even at the coarsest sizes studied. The graphs presented will be used for hazard analysis in estimating the explosion potential of a dust under a given set of operating conditions and designing explosion preventive measures. The data collected lead to an extension of the current data for dusts as found in the literature.

ABSTRACT
In the Philippines, biogas has the potential to showcase sustainable energy resource for rural electrification owing to the dispersed characteristic of backyard farm swine industry as plotted using GIS. Barriers to promote backyard farm biogas plant were defined as the potential show-stopper of rapid biogas development in the countryside. Each barrier was discussed with corresponding perspectives to bridge the implied gaps where the study using AHP was utilized to address the issue on the poor quantity and quality of biogas production. Together with the results, criteria were identified and prioritized with the following relative weights: economical 40%, environmental 33%, social 19% and technical 8%. The alternatives used for the AHP process were also ranked with electrospun fibrous membrane at 30.4% as the highest rank presenting the viability of electrospun membrane purification technology for small scale low-pressured biogas plant. Very close second and third rank goes to polymeric membrane with 26.2% and pressure swing adsorption with 25.8% respectively. Last rank was amine absorption process with 17.6%. The electrospun fibrous membrane possess a great potential for promoting energy access in the Philippines where most rural areas out of more than 7,000 islands still use wood for cooking and candles for lighting..

CHARACTER RECOGNITION USING NEURAL NETWORK

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/90-92

  Authors:Kauleshwar Prasad, Shubham Agrawal
 

ABSTRACT
In this paper, Character recognition (CR) system based on Artificial Neural Networks (ANNs) is discussed. Neural networks are mostly used to solve sample-recognition problems. One of these is character recognition. With the help of Matlab’s Neural Network Toolbox, I tried to recognize printed and handwritten characters by projecting them on different sized grids. The first step is image acquisition which acquires the scanned image followed by noise filtering, smoothing and normalization of scanned image, rendering image suitable for segmentation where image is decomposed into sub images. Feature Extraction improves recognition rate and misclassification. The Artificial Neural Networks is trained using the Back Propagation algorithm. In the proposed Character recognition system, each typed English letter is represented by binary numbers that are used as input to a simple feature extraction system whose output, in addition to the input, are fed to an Artificial Neural Networks. Afterwards, the Feed Forward Algorithm gives insight into the enter workings of a neural network followed by the Back Propagation Algorithm which compromises Training, Error calculation, and Modifying Weights.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/93-97

  Authors: Monika Arya
 

ABSTRACT
This Cloud computing is a set of IT services that are provided to a customer over a network on a leased basis and with the ability to scale up or down their service requirements. It is an Internet-based computing solution which provides the resources in an effective manner. Cloud computing offers an innovative business model for organizations to adopt IT services without upfront investment. Cloud computing has many advantages such as flexibility, efficiency, scalability, integration, and capital reduction. Moreover, it provides an advanced virtual space for organizations to deploy their applications or run their operations. With disregard to the possible benefits of cloud computing services, the organizations are reluctant to invest in cloud computing mainly due to security concerns. Security is one of the main challenges that hinder the growth of cloud computing. Usually cloud computing services are delivered by a third party provider who owns the infrastructure. The idea of handing over important data to another company is worrisome; such that the consumers need to be vigilant in understanding the risks of data breaches in this new environment. This paper introduces a detailed analysis of the cloud computing security issues and challenges focusing on the cloud computing service delivery types. Various security issues and challenges are discussed in this research, and possible opportunities are stated. Our main area of concern in this paper is to highlight security issues and their existing solutions in SaaS model. This best-known branch of cloud computing represents a delivery model in which applications are hosted and supervised in a service provider's datacenter. The paper illustrates the assorted security issues of cloud computing with respect to SaaS service delivery model.

 

A FUZZY LOGIC MODEL TO FORECAST STOCK MARKET MOMENTUM

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/98-101

  Authors: Partha Roy, Ramesh Kumar and Sanjay Sharma
 

ABSTRACT
Forecasting is a very complex process and requires considering many dimensions. The stock market index values are very chaotic in nature and highly random, hence forecasting stock market values is a very challenging job. Financial forecasting that too stock market prediction is an important area of interest to stock investors, stock traders and applied researchers. To determine the momentum of the market helps in predicting future market movements and that helps to take effective buy and sell decisions. The experts in the stock markets use many attributes like historical prices, company earnings, company orders, etc. and in this paper the NIFTY-50 index historical prices are only used, hence it becomes far more difficult to forecast. The proposed fuzzy model helps in identifying the momentum (bullish, neutral or bearish) of the index. It can forecast the short term momentum by considering 14 day historic data as the base for predicting future 5 day movement or momentum. The consecutive close-open values are fuzzified to get a fuzzy momentum value, the momentum which is either bullish, bearish or neutral continues to some extent i.e. for few days and this idea helps to forecast the momentum. The results found suggest that fuzzy modeling for this purpose is very promising.

 

CHATBOT ASSISTING: SIRI

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/102-103

  Authors: Harshita Phatnani, Mr. Jyotiprakash Patra and Ankit Sharma
 

ABSTRACT
Siri is an intelligent personal assistant and knowledge navigator which works as an application for Apple's iOS. Looking at it from a programmer’s perspective, it seems to me that Siri consists of three layers: a speech-to-text analyser, a grammar analyser, and, a set of service providers. Siri began as a DARPA-funded project at SRI International back in 2003 and was spun out and setup as Siri International (SI) after DARPA funding ended in 2008. SI raised nearly $25 million and launched the Siri Digital Assistant as a free App on the App Store in early 2010. Four months later, Apple acquired SI for around $200 million. Since then Apple integrated Siri technology with iOS and extended the backend architecture that allows Siri to work so well. The free Siri Digital Assistant App was removed from the App Store (9/15/11) and Apple ceased supporting Siri on any device other than the iPhone 4S after 10/15/11.

A ONTOLOGY OF KNOWLEDGE REPRESENTATION:AN APPROACH TO KNOWLEDGE GRAPH

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/108-109

  Authors: Shankha De
 

ABSTRACT
Knowledge is the collection of raw facts and rules. Knowledge is the information about objects, attributes and relations between objects, situations, events, states and time, causes and effects. Knowledge representation provides the way to represent all the above defined things. The main characteristic of knowledge is that it is hard to characterize. So it is very difficult to us to represent it properly. We have to represent the knowledge in such way that we can infer new knowledge also. Recently new concept of knowledge graph is introduced by structuring knowledge into a graph. There are various techniques available to represent the knowledge. But none of them is perfect. In this paper I have analyzed different knowledge representation technique and the major challenges of knowledge graph.

3D PRINTING: ENDLESS OPPORTUNITIES

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/137-140

  Authors:Harsh Bafna, Prof. Sarang Pitale
 

ABSTRACT
3D printing (or additive manufacturing, AM) is any of various processes used to make a three-dimensional object. In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.
3D printing in the term's original sense refers to processes that sequentially deposit material onto a powder bed with inkjet printer heads. More recently the meaning of the term has expanded to encompass a wider variety of techniques such as extrusion and sintering based processes. Technical standards generally use the term additive manufacturing for this broader sense.

  Authors: Dileep Kumar Sahu
 

ABSTRACT
In this study we dealt with the blur caused by motion in which the cameras follow out of plane translatory motion. Solving the deblurring problem of motion blur has significant importance and applications in forensic science, computer vision and video processing where the restoration of the features in the given image or video sequence is mandatory for the preservation of essential details which are normally blurred or fade out due to the blur caused by motion. The study formulates an effective deblurring algorithm for feature restoration and eliminating the effects of motion blur using decomposable pixel component analysis. Furthermore, the existingmethods are also analyzed & compared in the study. The algorithm is verified and testified with the several natural deblurred images which weren’t as efficient as those of previous ones.

 

MACHINE LEARNING APPROACH FOR RESOLVING PRONOMINAL ANAPHORA USING HINDI DEPENDENCY TREEBANK

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/155-159

  Authors: Seema Mahato and Dr. (Mrs.) Ani Thomas
 

ABSTRACT
Machine Learning facilitates the computers to mimic human intelligence by applying a set of rules to massive amounts of trained data and identifying patterns to make decisions and adapt based on what patterns are still uncovered. A number of applications ranging from spam detection, facial recognition, product recommendations to credit-card fraud detection, all of them apply machine learning procedures. The focus is on presenting machine learning approach for resolving anaphora’s in Hindi Sentences. The availability of Dependency Treebank for Hindi has motivated many researchers to explore and exploit its information for natural language processing such as anaphora resolution. Capturing the Treebank generated by a parser has been seen as a key element in resolving anaphora. An attempt is to show how the part-of-speech (POS) tagging, chunking and morphological information generated by the Hindi parser in the form of Hindi Dependency Treebank (henceforth HDT) can be used to derive rules for resolving Hindi anaphora and implementing the same in machine learning. The steps for resolution of pronominal anaphora are based on the syntactic cue provided by the HDT.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/167-170

  Authors: Amit Sarda, S K Moullick
 

ABSTRACT
Nuclear reactor pressure vessel is subjected to neutron irradiation in addition to the conventional effects disturbing any conventional pressure vessel during operation. In general, neutron irradiation changes the mechanical properties of the vessel steel, which influence the operational conditions of the pressure vessel, and can bound the, life time of the reactor pressure vessel. To extend the plant life and to enhance the safety at work, integrity and reliability of reactor pressure vessel (RPV) is an influential aspect to consider and study as because the main objective from a nuclear-industry perspective is to maximize and enhance the safety and the reliability of nuclear power plants and to extend their operation lifetime. From this point of view the reactor pressure vessel (RPV) is one of the critical elements, rated as the highest priority category 1 component in all different national safety rankings. As a part of the design of primary heat transport piping of pressurized heavy water reactors, which uses bimetallic weld components, under high neutron flux over considerably long period of time it may become brittle, resulting in cracks which may lead to accidents. Hence, it is essential to assess the structural integrity of the vessel under such scenario. During the operation of the reactors, bimetallic welds become brittle under the effect of irradiation. Such an irradiation embrittlement is manifested by an increase in the ductile-to-brittle transition temperature. Irradiation embrittlement can produce changes in material properties and can cause crack growth. Cleavage fracture and ductile tearing are two competing mechanism in the ductile-to-brittle transition regime of bimetallic welds. Embrittlement results in a raise in the ductile-to-brittle transition temperature, which is normally used as indicator of the degradation status of the material. Information on such fracture behavior of the material at transition region is mandatory to quantify the inherent safety margin available under such undesirable events. A lot of studies have been carried out on the irradiation behaviors of nuclear materials to solve the practical problems associated with a nuclear reactor and to meet the desired mechanical properties to the future design of nuclear reactor. This paper aims to highlight the issue of irradiation in bimetallic welds.

 

WEB-BASED EXPERT SYSTEM FOR SOME DEFECT IN SAND CASTINGS

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/171-174

  Authors: A. Rai, S. K. Ganguly
 

ABSTRACT
Sand castings process is vulnerable to many defects resulting in high rejection rates. A foundry that produces within 5% rejection is considered to be normal while the quality today is expected to conform part per million defects. Hence control of defects has become an important issue for the foundry industry. Casting defect diagnosis and analysis is influenced by multiple events like Melt-preparation, Mould-core preparation, Pouring, Solidification and Fettling. Knowledge based expert systems have been used to support decision-making for processes that are influenced by multiple events. Expert system based on fuzzy representation of process boundaries has been developed to determine well in advance the possibility of occurrence of some major defects, which may occur in the gray iron castings produced by sand casting process. The expert system developed is capable of defect identification, and its diagnosis and can thus help product designer and foundry engineers to take decisions regarding preventing the possible defects.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/177-180

  Authors: Archana Tamrakar, S. N. Siddique
 

ABSTRACT
For laser cutting operations many suggested parallel robot and many goes for serial robot. The drawback of parallel robots are their limited workspace but show high structural stiffness and accuracy in operation and for serial manipulator, workspace is comparatively large but low in stiffness and accuracy. The hybrid combination of both serial and parallel manipulator serves the purpose of increased workspace, stiffness and accuracy. This paper deals with a study of combinations of parallel and serial manipulator developed for high-speed laser cutting. These not only allow pure translations but also capable of rotation of the moving platform carrying the laser equipment for this feature the machine is suitable for complicated cuttings on plane metal sheet. The proposed hybrid structure seems to be efficient and industrially competitive for all the laser-cutting applications in which high speed, extreme accuracy and flexibility are required in a difficult and complicated metal sheet cutting.

  Authors:B.L. Maharana, Dr.H. Chnadra
 

ABSTRACT
Continuously growing industrialization, motorization and civilization of the world has led to a sudden increase in the demand of fossil fuels. Fossil fuels resources are continuously depleting and these fixed reserves are very much concentrated in definite regions of the world. Countries like India having limited resources of fossil fuel are in front of energy crisis, because 70% the crude petroleum is imported here. Therefore, need for alternative fuels obtained from alcohol, biodiesel, vegetable oils etc. are gaining importance day by day. In this paper biodiesel and its blending with pure diesel has been taken for the experimental work to evaluate the performance of four stroke diesel engine. The experimental result shows that the performance of diesel engine was satisfactory with the use of biodiesel in contrast to pure diesel.

 

A REVIEW OF STRUCTURAL ANALYSIS OF KINEMATIC CHAINS

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/184-188

  Authors: Sankalp Verma, Dr. P. B. Deshmukh
 

ABSTRACT
The structure of a kinematic chain is defined by the pattern in which the constituent links of the mechanism are interconnected and deriving the characteristics of the mechanism independent of metric properties of the mechanisms. The study of the nature of connection among various links of a kinematic chain is known as structural analysis or topological analysis. Over the century, a lot of researchers paid attention for analyzing the structure of a kinematic chain which leads to a systematic development of methods of identification and isomorphism which forms the core of the structural analysis and synthesis of kinematic chains and mechanisms. The motives behind the studies range from the desire for an orderly classification system, to studies of mechanism mobility, to the hope of identifying heretofore unknown mechanisms, to the need for the automated recognition of topology in generalized computer-aided design programs. Analysis and synthesis of kinematic chains is very important from the view point of mechanical engineering design and it is only natural that many researchers have directed their efforts to study various aspects of mechanisms. This paper represents a broad review of the extensive literature available on the subject with a view to trace its history highlighting major trends and discussing significant contributions. Some problem areas needing further attention of researchers are also presented.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/196-198

  Authors: Duleshwar Singh Sahu and S. N. Siddique
 

ABSTRACT
The Taguchi method is a powerful problem solving technique for improving process performance, yield and productivity. It is a statistical approach to optimize parameters and improve the quality of components that are manufactured. The objective of this study is to illustrate the procedure adopted in using Taguchi Method to light weight rolling of merchant products. The orthogonal array, signal-to-noise ratio, and the analysis of variance are employed to study the performance characteristics rolling operation. In this analysis, factors namely soaking and rolling temperatures; roll cooling and metal feeding rate were considered. Accordingly, a suitable orthogonal array was selected and experiments were conducted according to the procedure of Taguchi approach. Light weight rolling is the rolling with negative side of tolerance and has always been of very important concern, because profiles rolled with negative tolerance have always been preferred by the customers as they purchase in tonnage and getting more amount of length is their primary concern which is fulfilled by light weight rolled product. Light weight rolling is worthwhile in the following context also, that it offers higher strength to weight ratio, considerable structural saving etc.

 

REVIEW ON RECOVERY AND UTILIZATION OF WASTE HEAT IN INTERNAL COMBUSTION ENGINE

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/199-205

  Authors: M. Dubey*, A. Arora, H. Chandra
 

ABSTRACT
Today the demand of energy is increasingly worldwide problem regarding rapid economy development and lacks in supply of energy. Recently exhaust waste heat and environmental pollution has been more emphasized of internal combustion engine. About 75% of the fuel energy loses through the engine coolant, exhaust and surface radiation, result the entropy will rises and serious environmental pollution occur, so it is required to utilize waste heat into useful work. The energy released during combustion power produced by the burning fuel is used for work output is around 20% only. Major part of the heat supplied is not used as work output in an internal combustion engine, but dumped into the atmosphere as waste heat. The recovery and utilization of waste heat not only conserves fuel but also reduces the amount of waste heat and greenhouse gases damped to environment. Depending on engine load approximately 30-40% of the energy is recovered that rejected to the environment through exhaust gas. The overall efficiency of an engine can be improved when waste heat energy is tapped and converted into usable energy. The study shows the loss of exhaust gas energy and also describes the availability and possibility of waste heat from internal combustion engine. The best way to recover the waste heat and saving the fuel is waste heat recovery system.

 

SUITABILITY OF B-SPLINE COLLOCATION TECHNIQUE TO ARRIVE AT APPROXIMATE SOLUTIONS FOR STRUCTURAL PROBLEMS

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/206-208

  Authors: Deepak Mahapatra
 

ABSTRACT
This work is primarily focused on identifying the potential of B-spline collocation technique in finding approximate solutions for structure based boundary value problems. A mathematical model of an available structure problem (fourth order differential equation for a cantilever beam with given boundary conditions) is considered. A numerical solution to this problem is approached using B-spline collocation technique. A collocation technique involves satisfying the differential equation at finite number of points called collocation points. Here we use the Greville abscissa method to find the collocation points. B-spline basis functions of sixth order are used to approximate the function. Results are then compared with those in the available literature. It is concluded that this technique can be efficient and simpler to find solutions to boundary value problems of structural problems.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/218-222

  Authors: Shubhrata Nagpal, Nitin Jain and Shubhashis Sanyal
 

ABSTRACT
The stress distribution in isotropic/orthotropic plates with different discontinuities under in-plane static loading has been studied widely. In present paper plate with elliptical hole under in-plane loading has been considered for analysis. Variation in stresses for different a/A ratio (where a is major axis of ellipse and A is width of plate) and b/a ratio (where b is minor axis of ellipse) have been studied. The a/A and b/a has been considered from 0.1 to 0.6 and 0.3 to 0.5 respectively at an interval of 0.1. Stress concentration factor (SCF) has been mitigated by introducing auxiliary circular holes around main elliptical hole. The size and position of auxiliary hole have been optimized for maximum mitigation in SCF. The percentage reduction in SCF after introducing auxiliary holes has been represented graphically. Finite element method has been adapted for analysis. The FEM is carried out using ANSYS software. The results obtained are encouraging in the form of appreciable mitigation of stress concentration.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/223-226

Authors: Raghwendra Banchhor, S.K.Ganguly
 

ABSTRACT
Casting defects causes losses for a foundry, loss of time for reworked item and loss of material for scrapped unusable products. Investigating the reason followed by eliminating the causes will reduce defect percentage and positively contribute to productivity.
In the vertically parted automatic flaskless green sand casting process the pouring position of mould string is an important parameter to be decided before pouring the mould string to avoid casting defects like fins and metal run out. Fins and run-out are the casting defects which may occur due to mould separation caused by unbalanced metallostatic force of liquid metal. This study proposes a mathematical relationship to predict the optimum pouring position of the mould string with varying pattern plate utilization, sand metal ratio and metallostatic head in Disamatic moulding line. A table is presented to guide the operation team to predict the optimum pouring position

  Authors: Raghwendra Banchhor, S.K.Ganguly
 

ABSTRACT
DISAMATIC is an automatic production line used for fast manufacturing of flaskless sand moulds for green sand casting. This process is commonly used to mass manufacture of metal castings for the automotive and machine industry. One of the essentials at the very start of the line is to ensure correct and consistent sand quality in order to optimize mould stability and avoid scrap. “Mould stability means higher throughput and less scrap”. Within this study models aiming to establish relations between the input value and related output value were developed on a data set collected from a DISAMATIC foundry. Models for moulding sand characteristics have been proposed using multiple linear regression analysis and ANN and a comparison is made between regression models and ANN models.

  Authors: Yugal Kishor Sahu, S. K. Moulick
 

ABSTRACT
A semielliptical crack in a thick walled cylinder has been considered for the analysis. Stress intensity factor is the parameter in fracture mechanics to calculate the effect of crack on the component strength. In this research paper three dimensional crack and cylinder are modeled by using finite element analysis program ANSYS 14.0. The main objectives of this paper are to develop ANSYS Parametric Design Language (APDL) codes to facilitate modeling of different types of cracks in cylinders and by using these codes the effect of some parameters of the problem like crack location, cylinder's radius to thickness ratio (R/t), the crack geometry ratio (a/c) and crack minor axis to cylinder thickness ratio (a/t) on stress intensity factors for the crack has been examined. In this paper stress intensity factor for single semi elliptical crack has been analyzed in linear elastic fracture mechanics regime by calculating stress intensity factor and also validated with previous noteworthy literatures.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/236-241

  Authors: Saurabh Verma, S. K. Mishra and S.K. Moulick
 

ABSTRACT
Abrasive water suspension jet (AWSJ) machining process utilized increasingly in industrial applications. It is a non-traditional machining process and involves complex mechanics. A nozzle is required to perform abrasive water suspension jet machining for material removal with the help of very high velocity of water suspension jet. The main problem of AWSJ machining process is nozzle wear during the process. The wear depends on various parameters such as water jet characteristics, abrasive size and nozzle geometry, etc. The nozzle wear is not fully understood experimentally; also the uncontrolled nozzle wear can affect the effectiveness and surface finish obtained through the AWSJ machining process. In the present work, the effect of geometrical parameters of single step nozzle and abrasive size on skin friction coefficient at the wall of nozzle due to wall shear stress and jet exit kinetic energy has been analyzed by ANSYS software. This analysis is totally depends on nozzle geometry and nozzle material is taken same for all cases. This analysis can be highly helpful for understanding nozzle wear during the AWSJ machining process.

 

UTILITY OF TAGUCHI BASED GREY RELATIONAL ANALYSIS TO OPTIMIZE ANY PROCESS OR SYSTEM

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/242-250

  Authors: Vikas Sukhdeve, Dr. S.K.Ganguly
 

ABSTRACT
In this paper it has been discussed how Taguchi based Grey Relational Analysis is implemented to optimize a set of operational parameters which are called as input variables of any process to achieve best result of any performance parameter, which is also known as response variable, of that process. Taguchi based Grey Relational analysis is actually a Design of Experiment (DOE) approach to create best combination of experimental variables or input variables to get desired response variable. DOE is a systematic approach for investigation of a system or process. A series of structured tests are designed in which planned changes are made to the input variables of a process or system. The effect of these changes on a pre-defined output then assessed. DOE is important as a formal way of maximizing information gained while minimizing resources required. It has more to offer than ‘one change at a time’ experimental methods, because it allows a judgment on the significance to the output of input variables acting in combination with the other.
In this article a detailed discussion has been taken place on different aspects of Taguchi design like ‘Orthogonal Arrays’, ‘Signal-Noise ratio’, ‘MSD analysis’ and ‘Analysis of Variance (ANOVA). After discussion on different aspects of Taguchi design different aspects of Grey Relational Numerical Method like ‘Processing of Primitive Data’, ‘Grey Relational Coefficient’ ‘Grey Relational Grade’, ‘Grey Relational Ordering’ and ‘Grey relational Matrix’ have been done.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/251-255

  Authors: Riteshkumar Shrivastava, Dr.Sridhar K
 

ABSTRACT
Globalization has changed the concept of quality & customer satisfaction, and has established new benchmarks. Customer’s choices and perceptions have also been changing rapidly. This leads to high variability and short product life cycle. Industrial and manufacturing enterprises have to struggle to gain the competitive edge and meet or exceeds the aspirations of customer. In this context, adoption of proper tools & techniques leading to higher productivity and quality becomes the key issue. Japanese manufacturer were first to meet these challenges by introducing many innovations in manufacturing system, and its management. Changing over to Just-in-time (JIT) manufacturing philosophy, has a lions share in most Japanese success stories. There are various tools to realize JIT i.e. TQM, TPM, Kanban, SMED, cellular manufacturing. Kanban is one of the mechanisms to establish a pull system.A pull system comprising Kanban can be implemented in large country like India with the help of “Milk Run system”, which establishes a supply chain. This paper discusses in brief the case of implementation of Kanban system in a Tractor Manufacturing Company and its cost analysis for gaining the productivity advantage. The issues like quality & high inventory levels are addressed by designing and implementing a Simple (single card) Kanban system in a warehouse of the Tractor Assembly Plant. After implementing & operating the system for a pilot batch of components, its implications on the productivity and quality are assessed.

 

MAINTENANCE STRATEGY AND DECISION MAKING -AHP METHOD

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/256-258

  Authors: Chandrahas, Santosh Kumar Mishra and Deepak Mahapatra
 

ABSTRACT
Maintenance strategy plays a very important role in all kind of manufacturing industries. Each maintenance strategy has their characteristics, importance and drawbacks. Performance of a machine depends on the type of maintenance strategies employed on it. Machines used in industries need proper maintenance because failure of machine may cause the production loss. Maintenance strategy may vary from one machine to another machine because of the various conflicting factors like safety, cost, customer satisfaction etc. Factors affecting machines performance need to identify and control. Use of inappropriate maintenance strategy may increase the maintenance cost. Increase in maintenance cost will increase the production cost. Selection of a maintenance strategy to a particular machine or group of machines is a problem of decision making and it is always a challenging task for maintenance Manager/Engineer. By using the decision making tools like AHP, this problem can be solved. Use of AHP method also facilitates to calculate the weight of factors through which decision maker can analyze the difference between actual condition and required condition. Present research work shows that the problem of selecting an optimum maintenance strategy to a machine can be overcome by using decision making tool (AHP).

 

IMPLEMENTATION OF GREEN SUPPLY CHAIN MANAGEMENT IN STEEL INDUSTRIES IN CHHATTISGARH

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/259-260

  Authors: Rajesh Kumar, Shiena Shekhar
 

ABSTRACT
The world is flying on the wings of technology at a very rapid pace. The demand of the users is compelling the designers and manufacturers to cater to the needs and expectations faster and better. The existing and even the new products are becoming costlier on account of increase of the price of the inputs. It is resulting in the decrease of sales and the corresponding reduction in profits which has made many industries and organizations to think critically in the direction of reducing the effective cost of raw materials and the cost of finished products till it reaches the end user. As most of the elements of the production and manufacturing units are optimized in terms of efficiency and cost so there arises a need to look into other aspects of production, inventory and supply for further reduction of the elemental cost and ultimately leading to reduced price of the product. The steel industries have a very large number of inputs to deal with including machine components and raw materials and also a large number of vendors. The degree of importance for each component varies and so the inventory also varies. When the steel industry is operational it also becomes the reason for severe pollution of air, water and soil. Thus, the manufacture of steel also leads to the development of air-borne diseases, damage to the marine life and also rending the water as unfit for human use and the depletion of fertility of soil.
The authors have tried to study the level of implementation of Green Supply Chain Management in the steel industries in the state of Chhattisgarh and suggest the mode of action for a green environment and also for increasing the profitability.

 

EL STUDIES ON ROPPV POLYMER DIFFERENT THICKNESSES FILMS

 

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/261-264

  Authors: Anjali Kanojia
 

ABSTRACT
The optical properties and electroluminescence of ROPPV (2-5 – dialoxy-PPV) films of various thicknesses have been studied. The thickness of ROPPV layer on glass slide was measured by Fizeau fringes interferometric technique which varied from 200 to 400nm. The absorption spectra show that the absorption occurred only in ultraviolet region. Thick films show only one peak at 310 nm, whereas by decreasing the thickness, the peaks are obtained at lower wavelength also. Photoluminescence excited by violet light shows three peaks at 380,450 and 510nm and intensity is found to increase with thickness. Electroluminescence from ROPPV films was studied by applying different ac voltage at various frequencies. The light emission starts at certain threshold voltage and then increases with voltage. It is observed that higher threshold voltage is required for thicker films but at higher voltages these give brighter EL. The threshold voltage is found to increase with frequency. The EL spectrum shows two main peaks, one at 510 and the other at 450nm.

IJAERS/Vol. IV/Issue II/Jan.-March, 2015/265-267

  Authors: Anju Singh*, Dr.H.L.Vishwakarma
 

ABSTRACT
ZnO nanorods were prepared by a simple chemical precipitation method in the presence of capping agent PVP. X-Ray Diffraction result indicates that the synthesized undoped ZnO nano rods have wurtzite hexagonal structure without any impurities. It has been seen that the growth orientation of the prepared ZnO nano rods were [101]. XRD analysis revealed that the nanorods having the crystallite size 49 nm. The SEM image confirmed the size and shape of these nanorods. The diameter of nanorods has been found that 1.52 µm to 1.61 µm and the length of about 4.89 µm. It has also been found that at room temperature ultra violet (UV-Vis) absorption band is around 355 nm (blue shifted as compared to bulk). Electroluminescence (EL) studies show that emission of light is possible at very small threshold voltage and increases rapidly with increasing applied voltage. It is seen that smaller ZnO nanoparticles give higher electroluminescence brightness starting at lower threshold voltage. The brightness is also affected by increasing the frequency of AC signal.

ABSTRACT
The nanocrystalline SrS: Ce3+ phosphor powder has been synthesized by solid state diffusion technique. The as-obtained phosphor is characterized by means of X-ray Diffraction (XRD), field emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopic (EDX) studies. The FESEM result shows the surface morphology, agglomeration of particles and crystallite size etc. The results of XRD studies confirm the cubic structure of SrS phosphor exhibiting wider diffraction peaks. The EDX profile is used to confirm the presence of different starting materials in final product. The optical properties in terms of TL glow curve of SrS: Ce3+ are studied and discussed systematically. The TL peak falls in a temperature 145oC indicating the existence of trap center. The different TL kinetic parameters like shape factor, order of kinetics, activation energy and frequency factors are calculated using Chen’s peak shape method.

  Authors: Upma, Mohan L Verma and Rachna Singh
 

ABSTRACT
Starch is a carbohydrate consisting of a large number of glucose units joined by glycosidic bonds. An ab initio study based on density functional theory implemented in computational program SIESTA is the prime theme of present paper. In which LDA exchange co-relation environment is used to obtain density of states (DOS), projected/partial density of states (PDOS), charge density, electronic band structure of some potato starch. In the first step the structure of Potato starch (PS), glutaraldehyde (GA) and crosslinked PS-GA systems are optimized for lowest energy value. On the basis of band plot and PDOS, it can be stated that the system under study is electronically insulator but charge density analysis proves it as ionic conductors. Moreover, the contributions to the top of valence band (HOMO) and bottom of conduction band(LUMO) come predominantly from O s/p, C s/p and H s states, respectively. This is a preliminary and first study to observe theoretically the effect of cross-linking of GA in PS before its further application as an electrolyte in various electro-chemical devices.

ABSTRACT
Rice Husk Ash is one of the most active research areas that encompass a number of disciplines including civil engineering and construction materials. Rice Husk Ash (RHA) is an agricultural waste product which is produced in large quantities globally every year and due to the difficulty involved in its disposal, can RHA becoming an environmental hazard in rice producing countries. India alone produces around 120 million tons of rice paddy per year, giving around 24 million tons of rice husk per year and 6 million tons of rice husk ash per year. As the rice husk ash is piling up every day, there is a pressure on rice industries to find a solution for its disposal. It is most essential to develop eco-friendly concrete from RHA. RHA can be used in concrete to improve its strength and other durability factors. So we can use RHA as a partial replacement of cement in pervious concrete. In this research study the (OPC) cement has been replaced by RHA accordingly in the range of 10% and 20% by weight of cement for 0.30, 0.35, and 0.40 water/cement ratio. The compressive strength test and flexural strength test was carried out for 7, 14 and 28 days to measure the compressive strength and flexural strength of concrete. So the aim of the investigation is to study the behaviour of pervious concrete while replacing the RHA with different proportions in concrete. Test results have reflected, the compressive strength achieved up to 10% replacement of cement with RHA will be optimum without effecting properties of fresh and hardened concrete.

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/296-299

 

ABSTRACT
This paper explains the dynamic behaviour of ant colony optimization based Hybrid Active Power Filter (HAPF) accomplished for harmonic compensation under varying source/load conditions. ACO based controller is employed to extract fundamental component of current from non-sinusoidal currents of the considered supply system. Ant colony optimization (ACO) is a novel searching technique used in optimization problems. This paper describes ACO approach for optimization of coefficients of digital filters. In a design example, the order of a low pass filter and the parameters of its coefficients have been optimized in a discrete search space. AC analysis of the optimized filter has been conducted. Hybrid filter utilizing the merits of both shunt passive filter and shunt active filter for better compensation performance is applied in this work. Simulation and analysis of three phase four wire hybrid active power filter under distorted source conditions have been incorporated using MATLAB/ SIMULINK. The detailed simulation level results have been presented to validate the proposed methodology. The results show that filters obtained by ACO have simpler structures and better performance. .

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/300-304

 

ABSTRACT
In recent years the image processing mechanisms are used widely in several medical areas for improving earlier detection and treatment stages, in which the time factor is very important to discover the disease in the patient as possible as fast, especially in various cancer tumours such as the brain cancer, lung cancer, breast cancer. Process passed the available brain cancer images and its database in basic three stages to achieve more quality and accuracy in experimental results, firstly image enhancement stage which is used low pre-processing image techniques. Gabor filters using a Gaussian rule in which produced the best resultant enhanced images. In the image segmentation stage thresholding segmentation mechanism is used by Fuzzy C Means thresholding algorithm. Finally it relied on general features which helped for making a comparison between normal and abnormal images. Textures features of MR images have been provided. The analyses of both the normal and abnormal images are done. The ranges of both the types of images are calculated and then the comparison is performed between them. So, to determine the abnormality in the image, its texture features are compared and the feature lying inside the range is considered as abnormal image.

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/308-312

 

ABSTRACT
The balancing of an inverted pendulum by moving a cart along a horizontal track is a classic problem in the area of control. The inverted pendulum system inherently has two equilibria, one of which is stable while the other is unstable. The stable equilibrium corresponds to a state in which the pendulum is pointing upwards. In the absence of any control force, the system will naturally return to this state. The stable equilibrium requires no control input to be achieved and, thus, is uninteresting from a control perspective. The unstable equilibrium corresponds to a state in which the pendulum points downwards and, thus, requires a control force to maintain this position. The basic control objective of the inverted pendulum problem is to maintain the unstable equilibrium position. Therefore, this paper will focus on swinging the pendulum up to the unstable equilibrium position (vertically upright), and maintaining this state strictly. A state variable feedback controller is used in order to swing the pendulum to an upright and is maintained at that position. The effectiveness of State feedback controller is analyzed using Matlab / Simulink.

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/322-325

 

ABSTRACT
Power quality has always been an issue that is continuously increasing its importance in modern industrial and commercial applications. Voltage disturbances; for example the voltage sag , swell, noise etc. are the common power quality problems that appears due to increased use of a large numbers of sophisticated and sensitive electronic equipment in industrial systems. To overcome this problem, custom power devices are used. One of the most common device used to improve the quality of supply is the D-STATCOM which is the most efficient and effective modern custom power device used in power distribution networks. It is connected in parallel with the power electronic based device so that they can quickly improve the voltage sag problem in the system and restore the load voltage to the pre-fault value. The primary advantage of the D-STATCOM is keeping the users always on-line with high quality constant voltage maintaining the continuity of production. In this dissertation, a fuzzy logic controller method for D -STATCOM that protects a sensitive load, to counter voltage sag under non-linear loading condition is presented. D-STATCOM along with other parts of the distribution system are simulated using MATLAB/ SIMULINK .

Authors: Ashish Kumar Sinha, Ritesh Diwan, Dipesh Sharma

 

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/326-330

 

ABSTRACT
Power generation from the non-conventional sources is requiring today. Wind energy is one of the major fields, where different conversion methods have been proposed in order to produce electric power. In the previous 30 years, the size of wind turbines and the size of wind power plants have increased extensively. Applications such as reactive power compensation, static transfer switch, energy storage, and variable speed generations are usually found in modern wind power plants. Modern high power wind turbines are capable of adjustable speed operation and use either singly-fed induction generator (SFIG) or doubly-fed induction generator (DFIG) systems. SFIG for wind turbine is directly coupled to the grid has been successfully used in wind turbines for decades. The DFIG is variable speed induction machine. It is standard, wound rotor induction machine with its stator windings direct connected to the grid and its rotor windings connected to the grid through an AC/DC/AC pulse width modulated (PWM) converter. The AC/DC/AC converter usually consists of a rotor-side converter and a grid-side converter. By means of the bi-directional converter in the rotor circuit, the DFIG is capable to work as a generator in both sub-synchronous and over-synchronous operating area. Depending on the operating condition of the drive, the power is feed in or out of the rotor. This paper deals with the development and simulation of PI controller based pitch angle controlled DFIG system for wind turbines. Since the power generated by the wind turbine system is totally based on the speed of the wind, most of time the power generated is suffers (fluctuations in generated power) from the variation in the wind speed; one possible solution of this problem is to appropriately control the pitch angle to maintain constant power. Hence the basic idea behind the proposed work is the control of pitch angle to maintain constant power across the lines.

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/331-332

 

ABSTRACT
Quality control is applied in production process. The good condition of electrical machines can be obtained by using diagnostics. There are a lot of methods that can be used for diagnostics of electrical machines. In the literature, standard methods are based on a study of electrical signals. This project work start with a novel automated practical implementation for non contiguous rotor side broken bars detection and diagnosis in induction motors. In this work a method for detection and diagnosis of rotor side broken bars is there based on the spectral analysis via fast Fourier transform (FFT) and classification of the spectral response based on fuzzy controlled identifier. For the fault diagnosis objective, two features are selected from the spectrum of the stator current, first is the amplitude of the harmonics representing the broken bars defect 2sf (where s is the slip and f is the fundamental harmonics) and the second is the dc value. By using these obtained parameters a fuzzy identifier will there to identify the number of broken bars. For the designing of this fuzzy identifier these two parameters will be used as inputs where the decision about the state of rotor will be made. After the implementation of that work it will provide that this technique will able to efficiently detect the number of broken bars at rotor side.

Authors: Vijay Prakash Gupta, Vishwanath Prasad Kurmi, Amit Agrawal

 

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/333-337

 

ABSTRACT
This paper presents the performance of isolated 3-phase self-excited induction generator (SEIG) in micro-hydro power plant using water pump as load. The daily electrical load profile in remote mountainous region or area shows vast difference in minimum and maximum load on the generator operated in isolated mode.
Induction generators are most suitable types of generators for renewable energy conversion systems due to their advantages over conventional generators. The load on these generators has to be kept constant to maintain the voltage and frequency under permissible limits. Therefore under off-load conditions, the extra energy available can be utilized for other purposes such as operating water pump water heater and other need based applications rather than wasting the energy in resistive dump load. In this proposed work, the potential benefits of using water pump as load under light/off-load conditions have been explored.

Authors: Pooja Chandrakar, Ravi Mishra

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/338-342

 

ABSTRACT
The objective of image fusion is to combine information from multiple images of the same scene. The result of image fusion is a new image which is more suitable for human and machine perception or further image-processing tasks such as segmentation, feature extraction and object recognition. Different fusion methods have been proposed in literature, including multiresolution analysis. The double-density dual-tree complex wavelet transform (CWT), which is a DWT that combines the double-density DWT and the double density dual-tree wavelet transform (DDDTWT), each of which has its own characteristics and advantages.
Double-density Dual-tree Complex Wavelet transform is introduced to image fusion based on multiresolution, images are decomposed by double-density dual tree complex wavelet transform with multi-level, multidirection and shift-invariance and according to characters of low and high frequency coefficients respectively, different combination rules are adopted to fuse images and composite coefficients are reconstructed by double-density dual-tree complex wavelet inverse transform. Some fusion experiments are done by several sets of images with different modalities and objective performance assessments are fulfilled to evaluate fusion results. The experimental results indicate that the proposed approach can significantly outperform the traditional image fusion method based on Laplacian pyramid and discrete wavelet transform.

Authors: Smita Dubey, Swati Verma

 

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/343-345

 

ABSTRACT
Various Adaptive filtering methods are using to filter Cardiac signals. The two basic adaptive filtering algorithms are LMS (Least Mean Square) and RLS (Recursive Least Square). These Adaptive Algorithms are used to filter artifacts from ECG signal. Adaptive filter minimises the mean square error between the primary input, which is ECG with noise and desired response, which is either ECG or noise correlated with primary input. Various filter structures are presented to reduce diverse forms of noise. In this paper NLMS (Normalized Least Mean Square) method has been used to remove noise from the ECG (Electrocardiograph) signal. NLMS is the variant of the LMS algorithm. This algorithm is applied to the real ECG signal, which is collected by the MIT BIH database. The results show that by applying modification to the NLMS filter the output signal has improved signal to noise ratio and least mean square error.

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/346-350

 

ABSTRACT
Many areas in power systems require solving one or more nonlinear optimization problems. Particle swarm optimization (PSO), part of the swarm intelligence family, is known to effectively solve large-scale nonlinear optimization problems. This paper presents a detailed overview of the basic concepts of PSO and its variants. The proposed method utilizes the Particle Swarm Optimization (PSO) algorithm approach to generate the optimal tuning parameters. The paper deals with optimal tuning of proportional integral derivative (PID) controller for controlling the output obtained and hence to minimize the integral of absolute errors. The main objective is to obtain a stable, robust and controlled system by tuning the PID controller using Particle Swarm Optimization (PSO) algorithm. It is necessary to use PID controller to increase the stability and performance of the system. Fast tuning of optimum PID controller parameter yield high quality solution. This paper demonstrated in detail how to employ the PSO method to search efficiently the optimal PID controller parameters. The proposed approach had superior features, including easy implementation and good computational efficiency.

IJAET/ Volume VI/ Issue I/ Jan.-March.'2015/365-366

 

ABSTRACT
The home-environment primarily consists of the prevalent customs, codes & traditions of the community, it is at the same-time made highly personal by the human interaction involved – Due to former fact it can safely be said that a child first comes in contact with the mysteries of a community like as he sees it reflected in the mirror of family. Aspiration means the goal the individual sets for their self in a task which has intense personal significance for them as in which he/she is ego-involved because as aspirations are ego-involved success leads to increased self-esteem, while failure brings embarrassment, remorse and feeling of personal inadequacy and inferiority.
