IJAET/ Volume III/ Issue II/ April-June'2012/01-03

ABSTRACT
As the world is becoming increasingly more insecure, people are looking for new forms of security which are more reliable. Pupil recognition is one of the most leading technologies and it is the most effective, fast and reliable for the person recognition compare to any other well-known biometrics and is well suited to be applied to any access control system requiring a high level of security. In the proposed algorithm Eigen iris is extracted from the normalized iris images using Fisher Discriminant Analysis combined with Fuzzy membership. Euclidean classifier is applied to measure the similarity degree of two iris class and we make pupil recognition by measuring the area of each pupil using pixel unit. Decision is made using rank level fusion and ranks of individual persons are calculated using Borda count and logistic regression approaches.

IJAET/ Volume III/ Issue II/ April-June'2012/04-12

ABSTRACT
Gears are important element in a variety of industrial applications such as machine tool and gearboxes. An unexpected failure of the gear may cause significant economic losses. For that reason, fault diagnosis in gears has been the subject of intensive research. Vibration signal analysis has been widely used in the fault detection of rotation machinery. The vibration signal of a gearbox carries the signature of the fault in the gears, and early fault detection of the gearbox is possible by analyzing the vibration signal using different signal processing techniques. In this paper, a review is made of some current vibration analysis techniques used for condition monitoring in gear fault.

IJAET/ Volume III/ Issue II/ April-June'2012/13-16

ABSTRACT
The orientation of space satellites in stationary orbits gradually change with time. Their attitudes have to be controlled so as to make the deviation from the reference zero by firing on-board jets. It is an optimal control problem which has been addressed in this paper by the maximum principle of Pontryagrin. It has revealed that a relay element is required to minimize the response time, backed up by a dead zone to minimize the fuel consumption, and a limiter to minimize the energy. A controller has been designed along with a full order estimator using linear state variable feedback. This type of compensated linear controllers gives satisfactory performance for limited dynamic range and limited input. The design has been made by specially constructed programs and the results have been checked up using MATLAB tools.

IJAET/ Volume III/ Issue II/ April-June'2012/20-25

ABSTRACT
Strength of concrete is commonly considered its most valuable property, although in many practical cases other characteristics, such as durability and permeability, may in fact be more important, Nevertheless, Strength usually gives an overall picture of the quality of concrete. Water cement ratio and compaction effects vital role for strength of concrete, In this experimental study seems the compressive strength of uncontrolled concrete is decrease about 56% to 59% with respect to controlled design mix concrete. We observed compressive strength of repaired specimen (of uncontrolled concrete) by epoxy, acrylic base and rubber base injection grouting and surface repair, it increase 76%, 25% and 20% compressive strength than honeycombed specimen respectively. We also study and find flexural strength of repaired specimen by epoxy, acrylic base and rubber base injection grouting, it increase 20%, 15% and 12% flexural strength than honeycombed specimen respectively. It was also noted that compressive strength of various repair materials like Microconcrete is 117% higher than design mix (Controlled) concrete and compressive strength value of rubber base PMM is 20% higher with respect to concrete and compressive strength of acrylic base PMM is 25% higher than concrete.

IJAET/ Volume III/  Issue II/ April-June'2012/30-33

ABSTRACT
Structural control system has been recognized as a very efficient tool for controlling the seismic response of a structure during an earthquake. This paper presents Seismic design concept in which super structure is divided into several segments. Each segment may comprise a few stories and is interconnected by additional vibrational isolation systems. The seismic response of a typical segmental building subjected to the N-S component of the 1940 El Centro earthquake and 1989 Loma Prieta earthquake inputs are evaluated and compared with the response of the corresponding fixed-base and conventional base-isolated buildings. The comparisons show that, when the superstructure is segmented, Roof acceleration as well as base displacement is reduced as compared to the fixed base and base-isolated building.

IJAET/ Volume III/ Issue II/ April-June'2012/49-53

ABSTRACT
To develop a Traffic Management System, System must provide run time data for security purpose. Data are gathered, saved and managed in a central database where, in principal, every Local system can access them putting data in a temporary database and then integrate them to a central. Security is an important aspect in our system to give confidence to the users to use their online services. The system combines real-time data for graphic displays with an open architecture for network and communications services we present architecture for the implementation. The implemented system has been used in a small scenario for traffic information in a city centre. Urban areas face increasingly acute vehicular traffic congestion. Some methods need to develop for measuring traffic flow on a real-time basis to improve traffic flow and increase safety. There are different technologies are available for transmission of road-way related data For e.g. Buried inductive loop detectors at intersections are extensively used in the USA and Europe to measure traffic speed, occupancy and volume on freeways and arterials. Video surveillance system also use CCTV camera which captures images and sends all traffic data in terms of images to the connected centre system but images with several drawbacks, including scalability, the cabling network’s cost and size, and the difficulty of providing video information to the public over the Internet. Owing to these limitations, System is design such a way that all traffic data are stored in low cost vehicle card .All gathered data are processed by local system and transmit data to remote FTP site. Central system manipulating the gathered data and generate tables by extracting every FTP folder which is generated by all local systems.

Authors: Rahul Uttamrao Patil, Dr. S. S. Gavade

 

IJAET/ Volume III/ Issue II/ April-June'2012/54-59

ABSTRACT
It is well fact known that automobiles are inefficient, wasting over 74% of energy stored in fuel as a heat. Major energy losses are engine losses, idle & standby, braking losses, aerodynamic drag etc. Thus only 26 % of the available fuel energy is used to drive the vehicle, i.e. to overcome the resistance from road friction. One important loss is the dissipation of vibration energy by shock absorbers in the vehicle suspension under the excitation of road irregularity and vehicle acceleration or deceleration. This paper presents design and finite element analysis of an electromagnetic energy regenerative shock absorber which can efficiently recover the vibration energy wasted in vehicle suspension system. Three alternative methods to recover this waste energy are studied and compared to get best alternative i.e. electromagnetic system. In this paper, design process of electromagnetic energy regenerative shock absorber is explained with due consideration to space limitations in commercial vehicle. A static magnetic analysis is used to analyze magnetic field distribution and to obtain optimum design. A preliminary equation is proposed to predict the generation performance of regenerative shock absorber depending upon input parameters like flux or velocity. Theoretical studies are showing that 32 watts of power (8x4 = 32) can be recovered from a vehicle moving with 45 mph speed experiencing 0.25 m/s vertical velocity.

ABSTRACT
The increase in population causes an increase in the quantity and type of urban and rural wastes. Such wastes are undesirable pollutants to the environment and time could even be a health menace. As far as rural wastes are concerned, there are enormous quantities of organic materials that are not utilized. “Vermicomposting technology” is a fast growing one with its pollution free, cost effective and efficient nature.
An experimental study was conducted to obtain the vermicompost using partially decomposed fruit waste with paper and tannery industry sludge’s. The earthworm species used for this process was Eudrillus eugeniae. The microorganism culture Pleurotus was added to enhance the degradation process. Moisture content was maintained by providing proper percentage of water. The partially decomposed organic waste and industrial sludge’s were converted into castings by earthworms. The castings was obtained on the top surface of the bin were in the range from 20 to 30 days depending on the type of waste and sludge used. The castings obtained were sieved, dried, tested and used as manure. Thus the vermicomposting process helps in the disposal of organic waste and industrial waste in a safe, economic and useful manner.

Authors: Barjinder S. Kaler, Dr. Munish Rattan

 

IJAET/ Volume III/  Issue II/ April-June'2012/87-91

ABSTRACT
The uses of wireless technologies, such as, mobile ad-hoc network (MANET) are increasing and it influences the development of new theories and structures for the communication. Wireless mobile communication consists of various nodes communicating with each other directly or through the relay nodes using multi-hope network system. There are many MANET routing protocols. These routing protocols are used to deal with dynamic communication. As mobile applications are increasing day by day, we need to analyze these routing protocols to handle more data load at high node density. It motivates the performance comparison of AODV, ZRP and OLSR protocols in mobile ad-hoc network. The comparison represents the more effective and reliable protocol for required mobile application. Using OPNET simulator software tool we can analyze these protocols performance on the basis of various matrices like End to End delay, Network load, Re-Transmission attempts and Throughput. The results are given with graphical representation.

Authors: B. Siva Konda Reddy, V.Rohini Padmavathi, Ch. Srikanth

 

IJAET/ Volume III/  Issue II/ April-June'2012/92-97

ABSTRACT
Wind is essentially the large scale movement of free air due to thermal currents. It plays an important role in design of tall structures because it exerts static and dynamic loads whose effects on a slender structure, such as a chimney are significant. The wind load exerted at any point on a chimney can be considered as the sum of quasistatic and a dynamic load component. This paper presents the Study of along and across wind effects on a 275m tall RCC lined chimneys for Ist & VIth wind zones of India and the results indicate that in shell completed condition at highest wind zone of VI (i.e basic wind speed 55m/s), along wind loads are governing rather than the across wind loads. The analysis is carried out using STAAD PRO &MS excel spread sheets.

Authors: Murad M. Bhunga, Dr. N. K. Arora

 

IJAET/ Volume III/ Issue II/ April-June'2012/98-100

 

ABSTRACT
There is enormous scope of use of FRP in strengthening of structural elements in India due to significant number of seismically deficient or structurally degraded buildings. Though the quantum of usage of FRP laminates in strengthening the structural elements have become multifold in recent years in India, there are no guidelines available in form of codes of practice for its application. Most of the designers use literature supplied by the manufacturer and ACI 440-2R for design of FRP laminates. As the stress block parameters of Indian code IS 456 is different than ACI, the design output will be different. Therefore, a need is felt to design the FRP laminated structural elements by including IS stress block parameters. In present work, an attempt is made to propose steps to design flexural element using FRP as per the IS stress block parameters, with comparison of ACI and IS method.

Authors: Priyanka A. Jadhav and Dilip K. Kulkarni

 

IJAET/ Volume III/  Issue II/ April-June'2012/101-104

 

ABSTRACT
The effect of water cement ratio on fresh and hardened properties of concrete with partial replacement of natural sand by manufactured sand was investigated. Concrete mix design of M20 (2900 psi) grade was done according to Indian Standard code (IS: 10262). Concrete cube, beam and cylindrical specimens were tested for evaluation of compressive, flexural and split tensile strength respectively. Workability was measured in terms of slump and compacting factor. The concrete exhibits excellent strength with 60% replacement of natural sand, so it can be used in concrete as viable alternative to natural sand. This paper puts forward the applications of manufactured sand as an attempt towards sustainable development in India. It will help to find viable solution to the declining availability of natural sand to make eco-balance.

Authors: J.Pradeep Kumar, K.Thirumurugan

 

IJAET/ Volume III/  Issue II/ April-June'2012/108-113

 

ABSTRACT
Titanium alloys have been widely used in industries, especially aerospace industries, due to their good mechanical and chemical properties. However, machining of titanium alloys involves expensive tooling cost at the expense of getting good surface roughness. This paper describes a comprehensive study of end milling of titanium alloys. The study investigated the optimum parameters that could produce significant good surface roughness whereby reducing tooling cost. The quality of design can be improved by improving quality and productivity in company-wide activities. It employed the taguchi design method to optimize the surface roughness quality in a computer numerical control end mills.Taguchi’s parameter design is an important tool for robust design, which offers a simple and systematic approach to optimize a design for performance, quality and cost. The control parameters were spindle speed, feed rate, depth of cut and type of end milling tool.Then,an orthogonal array of L27 (313) and analysis of variance (ANOVA) were carried out to identify the significant factors affecting the surface roughness. The best parameters were chosen based on the signal-to-noise ratio (SNR).The experimental results indicated that the most significant factors affecting the surface roughness of titanium alloy during end milling process were primarily the spindle speed used, secondly, the type of cutting tool used, thirdly, the feed rate chosen and lastly, the depth of cut chosen.

Authors: Patel Samir K., Prof. C. S. Sanghavi

 

IJAET/ Volume III/  Issue II/ April-June'2012/119-123

 

ABSTRACT
A large number of water-retaining earthen dams were affected by the earthquake. This paper examines dynamic analysis with time history methods of kaswati dam are located in Bhuj region by using of geo-studio 2007. The consequences of these problems were the dams performed reasonably in spite of being shaken by free-field horizontal peak ground acceleration (PGA) as high as 0.28g. The liquefaction occurred in upstream slope, downstream slope and foundation of dam due to cohesion-less soil in foundation. The procedure for assessing liquefaction potential uses the Cyclic Stress Ratio (CSR) as the measure for earthquake load. The procedure for assessing liquefaction potential typically uses the Cyclic Resistance Ratio (CRR) as a measure of the liquefaction resistance of soils and the Cyclic Stress Ratio (CSR) as a measure of earthquake load. For cohesion-less soils, CRR has been related to normalized SPT blow count, (N1)60, through correlations that depend on the fines content of the soil from field performance observations from past earthquakes. Factor of safety is obtained by ratio of Cyclic stress ratio to the critical stress ratio. For prevention of liquefaction replace liquefied soil with well graded soil in foundation and get factor of safety above 1 which indicate non liquefied soil.

ABSTRACT
Rough access point on enterprise network poses serious security thread. It is now well established that wired-wireless traffic correlation is the only robust way for comprehensive rough access point detection. One of the most important parts in network security which concerns with network administrators is the presence of rogue access points. Rogue access points, if undetected, can be an open door to sensitive information on the network. Many hackers have taken advantage of the undetected rogue access points in enterprises to not only get free Internet access, but also to view confidential information. Most of the current solutions to detect rouge access points are not automated and are dependent on a specific wireless technology. In this paper, we present a rogue access point detection approach. The approach is distinguish authorized WLAN hosts from unauthorized WLAN hosts connected to rogue access points by detecting rogue access points in a heterogeneous network comprised of wireless and wired subnets.

IJAET/ Volume III/  Issue II/ April-June'2012/131-134

 

ABSTRACT
Aim of this research work to use of corrosion inhibitor (CI) to prevent the corrosion of rebar at certain extent. The different tests were conducted (i.e. accelerated corrosion test, pull out test & compressive strength). The corrosion inhibitor (Krishna ConChem EPCO KP-200) is used in mix M20 & M40 with dosage of 0%, 0.5%, and 1.0% by weight of cement. From the test result of pull out strength test it was observed that no rust were present on the embedded bar and bond strength were increased 41% and 37% for M20 & M40 mixes respectively with 1% dosage of corrosion inhibitor (CI). Similarly compressive strength was increased about 6%. The slump values also observed higher with corrosion inhibitor. The rate of corrosion reduction noted due to addition of corrosion inhibitor during acceleration corrosion test. Hence research focus on use of CI in reinforced concrete work to prevent the corrosion.

ABSTRACT
A series of w-type hexagonal ferrites with the composition BaCoxCa2-xFe16O27 (x = 0.4, 0.8, 1.2, 1.6, 1.8 and 2.0) were synthesized using a Stearic acid gel route with and without presence of Cetyletrimethyle ammonium bromide. The precursors were calcinated at 950ºC for 4 hrs in a furnace and then slowly cooled to room temperature in order to obtained BaCoxCa2-xFe16O27 crystalline ferrite powder. The effect of cationic surfactant Cetyletrimethyle ammonium bromide (CTAB) on structural and thermal properties were studied. The structural properties of the samples were studied by using XRD, FTIR and SEM. Decomposition behavior is investigated by means of thermal analysis (TGA). Thermo gravimetric analysis confirms the high thermal stability of w-type hexagonal ferrite particles synthesized in presence of CTAB. The field dependent magnetic properties of prepared Ba-Ca hexaferrite particles were investigated at room temperature by using Vibrating Sample Magnetometer (VSM). The maximum coercivity and saturation magnetization of prepared w-type hexaferrite samples were determined by a VSM. The value of saturation magnetization depends on amount of cobalt substitution. The sample (x = 0.8) shows high saturation magnetisation (~71 emu/g), where as the sample (x = 2.0) exhibits low saturation magnetisation (~65 emu/g). Magnetic study reveals that prepared BaCoxCa2-xFe16O27 (x = 1.8 and 2.0) hexaferrite particles prepared in presence of CTAB possess single magnetic domain.The dielectric measurements were carried out at room temperature between the frequency range 100 Hz to 1 MHz.

IJAET/ Volume III/  Issue II/ April-June'2012/143-153

 

ABSTRACT
Adsorption is one of the Physico-chemical treatment methods, used in treating water and waste water. Activated carbon is commonly used as an adsorbent for treating the raw waste. But the cost of activated carbon is high; hence this method is not adopted in treatment plants. Adsorption process is possible to remove dissolved solids, B.O.D., C.O.D., Colour, heavy metals, organic acids etc. The prospects of using many low cost materials [available mostly as agricultural, commercial and industrial waste] as adsorbents for pollution abatement have been investigated extensively in recent years. The non conventional adsorbents process remarkable adsorption capacity for the removal of heavy metals like Cd, Cr, Cu, Fe, Hg, Mn, Ni and Pb, surfactants, dyes, colour, organics from the industrial and municipal effluent.
This paper represents the review of past work on removal of heavy metals by biosorption by using low cost adsorbents in natural and modified forms. Attempts are also made to cover all methodology and techniques for the removal of heavy metals, BOD, COD and TDS.

ABSTRACT
The constant infiltration rates of different soils under different soil conditions were calculated at Sangola, district solapur of Maharashtra region. Experimentation work was carried out on black cotton, clay, and sandy soil. Soil conditions considered for black cotton soil were compacted, ploughed, and harrowed, for clay soil unploughed and ploughed, and for sandy soil unploughed. The double ring infiltrometer method was used for measurement of infiltration rate. The study aimed to determine constant infiltration rates of those soils under different soil conditions and comparing it with the infiltration rates obtained by Kostiakov, Modified Kostiakov, Horton’s and Green-Ampt infiltration models. The values of various constants of the models were calculated by method of averages suggested by Davis (1943), and by graphical approach. For getting best fitting model for particular soil and soil condition the results obtained from various infiltration models were compared with observed field data and graphs were drawn. The parameters considered for best fitting of model were correlation coefficient and standard error. The results shown that, The Horton’s model, and Green – Ampt model were best fitting to observed field data to estimate infiltration rates at any given time with high degree of correlation coefficient and minimum degree of standard error.

ABSTRACT
MIG butt welds of IS 2062 E250 mild steel plates to be welded using CO 2 as shielding gas. Welding speed is select as process variable while arc voltage, welding current, wire feed rate distance between the nozzle and the plates are fixed in this experiment. The effect of weld speed on the weld bead profile is been discussed with the effect of weld speed on the fusion angle and wetting angle. The effect of weld speed on the weld bead dilution i.e. penetration area and reinforcement area also be discussed.

ABSTRACT
Public transport system faces severe problems in almost all countries of the developing world, although the situation varies from one country to another and even from one city to another. Public transport systems are plagued by chronic corruption and inefficiency, overcrowded and undependable service, congested roadways that slow down buses, and an operating environment that is often chaotic and completely uncoordinated. Development of any country basically depends upon the its cities development as cities play a vital role in promoting economic growth and prosperity. The development of cities largely depends upon their physical, social, and institutional infrastructure. In this context, the importance of intra urban transportation is paramount. This is followed by a discussion on the nature and magnitude of urban transport problems such as congestion, pollution, and road accidents. Building on this background, the article proposes policy measures to improve urban transportation in the cities. Indian cities cannot afford to cater only to private cars and two-wheelers and there has to be a general recognition that policy should be designed in such a way that it reduces the need to travel by personalized modes and boosts public transport system. This requires both an increase in quantity as well as quality of public transport and effective use of demand as well as supply-side management measures. At the same time, people should be encouraged to walk and cycle and government should support investments that make cycling and walking safer. This article provides an overview of urban transport system of Bhopal city. The article first reviews the trends of vehicular growth and availability of transport infrastructure in Bhopal city after that will suggest strategies for the improvement in the efficiency of public transport system.
