IJAERS/Vol. I / Issue III/April-June, 2012/09-11

Authors: M.A.FArediwala, M.A.Jamnu

ABSTRACT
This paper presents the results of an experimental research on the workability and compressive strength of self-compacting concrete. The work focused on concrete mixes having water/binder ratios of 0.40 and 0.50, which contained constant total binder contents of 500 kg/m3and 550 kg/m3, respectively. The concrete mixes contained three different dosages of a superplasticizer based on carboxylic with fly ash. The percentage of fly ash that replaced cement in this research was 15%. The workability tests utilized in this research were the slump flow, V-funnel and L-box which can be used to evaluate the passing ability of self-compacting concrete. Based upon the experimental results, there are some linear relationships between compressive strength and each of the workability tests executed here.

SIMULATION OF EMPLOYING CONSTANT VOLUME HEATING METHOD IN PLACE OF COMPRESSOR OF A VAPOUR COMPRESSION REFRIGERATION SYSTEM USING R11 AS REFRIGERANT

IJAERS/Vol. I / Issue III/April-June, 2012/12-15

Authors: P Ravikumar, P Sivamurugan

ABSTRACT
Refrigerators and air conditioners are the common and essential appliances in the household as well as industrial applications. Work input for most of these systems employing vapor compression cycle is electrical energy to run the compressor and the process is isentropic compression. This process can be replaced by constant volume heating process as the refrigerant works with minimum heat transfer. The specific volume of the vapor during heating process can be kept constant or be decreased by allowing additional mass of the refrigerant during heating process. Solar energy or the waste heat like exhaust gas of engines can be used as the source of heat energy. In this paper, simulation has been made to validate the Energy Efficiency Ratio (EER) of newly suggested system. Successful implementation of this concept may eliminate the use of compressor, thereby the electrical energy in R & A/C applications wherever heat energy is available and can create a revolution in the field of refrigeration and air conditioning.

IJAERS/Vol. I / Issue III/April-June, 2012/21-25

Authors: K. Vijay, Dr. R. Anitha

ABSTRACT
Neural schema mechanism is a new autonomous agent control structure that makes use of both neural network and symbolic constructs to learn sensory motor correlations and abstract concepts through its own experience. The mechanism can also learn which intermediate states or goals should be achieved or avoided based on its primitive drives. In addition, a psychological theory of consciousness is modeled that allows the system to come up with creative action sequences to achieve goals even under situations of incomplete knowledge. The result is an architecture for robust action selection that learns not only how to achieve primitive drives, but also learns appropriate sub-goals that are in service of those drives

Today construction line is an industry that requires working at ever-changing locations and work environments. In urban sector of India increasing numbers of workers have taken up construction work as a means of immediate employment, which provides cash earnings at the end of the day. The best way to protect workers against hazards is to control problems at the source. The problem regarding construction industry is not that the hazards and risks are unknown, but it is very difficult to accurately identify in a constantly changing work environment. To prevent health hazards at work, all possible hazards that may be encountered should be identified in advance. In the present study various types of hazards present in construction areas were identified and appropriate PPE for hazard prevention were suggested.

PHYSIOCHEMICAL PROPERTIES OF OIL BLEND AND THEIR EFFECTS ON LUBRICATION PROPERTIES

IJAERS/Vol. I / Issue III/April-June, 2012/35-38

Authors: Talkit Kailas Marotrao

ABSTRACT
Vegetable oil like palm oil, soybean oil, mustered oil, sunflower oil, was purchased from local super market. The physiochemical properties like viscosity, acid value of four different vegetable oils and their blends were evaluated. Palm oil and their blends with soybean oil are found to be more stable against rancidity than the other vegetable oil. For the stability against oxidation and melting point palm oil and their blends with soybean oil was found to be better. Palm oil and their blends with soybean oil show higher viscosity than other blends of vegetable oils. Due to higher viscosity of blends of palm oil with soybean oil at higher temperature as well as lower temperature blends of palm oil with soybean oil act as better lubricant due to its higher stability against oxidation and melting point. The acid value of vegetable oil and their blenders was evaluated. Palm oil and their blends with soybean oil show lower acid value than other vegetable oils. Lower the acid value reduces corrosion of metal. Thus, palm oil blenders with soybean oil are better choice as lubricating oil. This study will help the oil producing industry to find out the most economically viable vegetable oil blends as a lubricant.

IJAERS/Vol. I / Issue III/April-June, 2012/51-54

Authors: Thakrar Jatin. J, Dr. Rathod Pravin. P

ABSTRACT
Ethanol is an attractive alternative fuel because it is a renewable bio-based resource and it is oxygenated, thereby providing the potential to reduce particulate emissions in compression–ignition engines. In this review the properties and specifications of ethanol blended with diesel fuel are discussed. Special emphasis is placed on the factors critical to the potential commercial use of these blends. These factors include blend properties such as stability, viscosity and lubricity, safety and materials compatibility. The effect of the fuel on engine performance, durability and emissions is also considered. The formulation of additives to correct certain key properties and maintain blend stability is suggested as a critical factor in ensuring fuel compatibility with engines. However, maintaining vehicle safety with these blends may entail fuel tank modifications. Further work is required in specifying acceptable fuel characteristics, confirming the long-term effects on engine durability, and ensuring safety in handling and storing ethanol–diesel blends.

IJAERS/Vol. I / Issue III/April-June, 2012/55-64

Authors: S Elangovan, S Venkateshwaran, K Prakasan

ABSTRACT
In this paper an effective methodology is developed to determine the optimum welding conditions that maximize the strength of joints produced by ultrasonic welding by coupling response surface method (RSM) with genetic algorithm (GA). RSM is utilized to develop an effective model to predict weld strength by incorporating process parameters such as pressure, weld time and amplitude. Experiments were conducted as per central composite face centered design for spot and seam welding of 0.2 and 0.3 mm thick copper and brass specimens. An effective second order response surface model is developed by utilizing experimental measurements. Response surface model is further interfaced with the GA to optimize the welding conditions for desired weld strength. Optimum welding conditions produced from GA is verified with the experimental results and is found to be in good agreement.

OPTIMUM INLET TEMPERATURES IN SHELL AND TUBE CONDENSER USING EXERGY METHOD

IJAERS/Vol. I / Issue III/April-June, 2012/65-69

Authors: Hardik.B.Patel, N.S.Mehta

ABSTRACT
This paper focuses on evaluation of the optimum cooling water temperature during condensation of saturated water vapor within a shell and tube condenser, through minimization of exergy destruction. First, the relevant exergy destruction is mathematically derived and expressed as a function of operating temperatures and mass flow rates of both vapor and coolant. Optimum inlet temperature of coolant on the basis of exergy destruction and exergy efficiency with various condenser pressures are calculated using the MAT Lab program. Exergy destruction and exergy efficiency at different inlet temperature of cooling water under three different condenser pressures. For example, when condenser pressure decreases from 0.18bar to 0.10bar, exergy destruction decrease from 41755 kW to 30263 kW, and exergy efficiency increases from 3.98% to 5.7%, as cooling water temperature is 21ºC. For given operating condition optimum temperature of cooling water is 34ºC. Exergy destruction decreases from 31653 kW to 27350 kW when cooling water temperature increases from 30ºC to 34ºC. Exergy efficiency increases from 27.21% to 31.1% for optimum temperature of cooling water for given operating condition.

Authors:B.Jyothi, B.T.P.Madhav, V.V.S.Murthy, D.Ujwala, H.M.Ramesh, B.Harish

ABSTRACT
The selection of most suitable substrate for an antenna is a matter of prime importance. This is because the limitations of an antenna such as high return loss, low gain and low efficiency can be overcome by selecting appropriate substrate for fabrication of the antenna. The substrate properties such as dielectric constant, loss tangent have a pronounced effect on the antenna characteristics. This paper presents the comparative analysis of the return loss of a slot antenna for FR4, Rogers RT/duroid and Teflon substrates.

THERMAL ANALYSIS OF A PISTON OF RECIPROCATING AIR COMPRESSOR

IJAERS/Vol. I / Issue III/April-June, 2012/73-75

Authors: Bhaumik Patel, Ashwin Bhabhor

ABSTRACT
In this study, the wok is carried out to measure the distribution of the temperature on the top surface of the piston. which predicts that due to temperature weather the top surface of the piston may be going to damaged or broken during the operating conditions because damaged or broken parts are so expensive to replace and generally are not easily available. So it is possible to recover the damage or broken parts due to thermal analysis before taking into operations. It can be seen from that the prescribed operating temperature inside the cylinder penetrates the piston crown through nearly 75 % of its thickness before piston ring dissipates some of heat.

PERCENTAGE VARIATION EFFECT OF SILICA FUME AND RECYCLED AGGREGATES ON RECYCLED AGGREGATE CONCRETE

IJAERS/Vol. I / Issue III/April-June, 2012/76-80

Authors: D. N. Parekh and Dr. C. D. Modhera

ABSTRACT
Use of recycled aggregate (RA) in concrete can be useful for environmental protection and economical terms. Recycled aggregates are the materials for the future. It is well known fact that it is giving little lower strength than natural aggregate concrete. Though, if it is used up to 20% of replacement, than it can give almost similar strength to that of natural aggregate concrete. Hence it was necessary to improve strength of recycled aggregate concrete for higher recycled aggregate content. Silica fume was very popular material used for strength improvement. Hence popular mix of 1:1:2 was checked with different % of silica fume combination. 5%, 7% and 10% of silica fume were replaced with cement and 30%, 50% and 100% of recycled aggregates were replaced with natural aggregate and results were analyzed. Thus total nine trials were analyzed and conclusions were derived in detail.

Authors: Sunita Sharma, Dr. Shrikant Bodhe

ABSTRACT
The main objectives of a handoff procedure are, first, to minimize the number of link transfers and second, to minimize the handoff processing delay by correct choice of target BS/AP with speedy execution. This minimizes the probability of connection interruptions and reduces the switching load. If the handoff is not fast enough, the quality of the service experiences degradations. A handoff should be evaluated as to its impact on the mobile to network connection. In this paper we have discussed the simulation outline and designed simulation model for the research undertaken. The flow chart indicated is generic one. We have added only case specific condition for the performance evaluation for the algorithm in consideration.

HYBRID ELECTRIC VEHICLES: A REVIEW

IJAERS/Vol. I / Issue III/April-June, 2012/87-92

Authors: Ranaware A. A., Satpute S. T

ABSTRACT
In the coming years, hybrids can play a significant role in addressing several major problems faced by the world today. The hybrids could be a key element to address our growing energy insecurity and environmental problems. The hybrid vehicle achieves greater fuel economy and lower emissions than conventional IC engine vehicles, having significant battery storage capacity to store and reuse recaptured energy especially in stop-and-go traffic. Regenerative braking recaptures significant amounts of energy during braking that are normally wasted as heat. Hybrids can play a critical role in bring the technology of motors, power electronics, and batteries to maturity and in reducing their cost. Such changes are vital to the success of future hydrogen fuel cell and other zero emission vehicles. Hybrid technology can fill the midterm gap between immediate improvements to conventional vehicle fuel economy and the long-term hope offered by hydrogen fuel cells and alternative fuels.

IJAERS/Vol. I / Issue III/April-June, 2012/98-100

Authors: Jatinder Gill, Jagdev Singh

ABSTRACT
The effect of welding speed and heat input rate on stress concentration factor of butt welded joint of IS 2062 E 250 A steel plates by gas metal arc welding (GMAW) were studied. For this series of experiments were carried out at fixed wire feed rate, welding current , arc voltage ,distance between gas nozzle and plate, gas pressure and the vertical angle of welding. Thus Different samples were obtained by employing arc voltage of 20V, welding current of 110A, wire speed of 5.918 m/min and welding speeds of 94.83, 109.90, 120.00, 131.25, 140, 150 and 169.76 mm/min .The findings indicate that the weld bead geometry i.e. width of reinforcement, height of reinforcement, flake angle, and radius of notch get effected with the welding speed and heat input rate, thus the stress concentration factor also affected. The results shows that with increase in the welding speed, flank angle and weld bead width, reinforcement height decreases whereas notch radius increase thus stress concentration factor decreases. At the same time with increase in the heat input rate, flank angle and weld bead width, reinforcement height increases whereas notch radius decreases thus stress concentration factor increases.

COMPRESSIVE STRENGTH OF CONVENTIONAL CONCRETE AND HIGH STRENGTH CONCRETE WITH TEMPERATURE EFFECT

IJAERS/Vol. I / Issue III/April-June, 2012/101-102

Authors: M.A.Pathan , M.A.Jamnu

ABSTRACT
High Strength Concrete is a material used in the construction where it is suitable for placing the concrete in difficult conditions and in structures with congested reinforcement. In case of unexpected fire, the concrete elements such as beams, columns etc will be subjected to extreme temperatures and need for assessment of their performance after fire. Hence, it is important to understand the change in the concrete strength properties due to extreme temperature exposure. This paper presents an assessment of effect of sustained temperatures on strength properties of High Strength Concrete and its comparison with ordinary Conventional Concrete. In order to study effect of sustained elevated temperature on the compressive strength, flexural strength, tensile strength of High Strength Concrete and ordinary concrete, the specimens of High Strength Concrete and ordinary conventional concrete were tested in laboratory. For various tests 36 cubes (150mmX150mmX150mm), 36 cylinders were cast and same for the ordinary concrete. The specimens were kept in oven at required temperature ( 50C, 100C, 150C, 200C,250C,) for 1 hour at constant temperatures. The results obtained were compared with the corresponding properties of normal concrete with the same water cement and air content.

EXPERIMENTAL STUDY TO EVALUATE SHORT-TERM DEFLECTIONS FOR TWO-WAY RC SLABS

IJAERS/Vol. I / Issue III/April-June, 2012/103-108

Authors: Manish Varma, Dr. Umesh Pendharkar, Dr. Ravi K. Sharma

ABSTRACT
Determination of deflection in structure is important from serviceability criteria. Codal provisions are available to calculate deflections in RC members in general. The codal provisions for calculation of short-term deflection in RC two-way slab are based on the effective moment of inertia (Ieff), The Ieff depends on the cracking moment (Mr) and maximum moment due to service load (M). Short-term deflections determined based on the provision for two-way RC slabs, are not comparable with experimental values. Even sometime negative deflection is obtained with the procedure. Present paper gives a method designated as Equivalent Load Method, in which equivalent load is calculated using Grashoff-Rankine formulae, and is considered to be acting on the slab. The deflection calculated using equivalent load method is found to be closer to experimental values. The negative deflection has been tackled in literature by applying a factor of 0.7 to cracking moment (Mr). The deflection thus calculated again differs considerably with the experimental values. In the paper, with the method, a procedure has been proposed in which instead of the factor 0.7 being applied to Mcr; cracking moment of inertia is proposed to be used in place of effective moment of inertia. The deflection thus calculated has been found to be comparable with experimental results. Experimental data obtained and data available in literature have been used to validate the procedure. Experimental work has been carried out for two end conditions i.e. fixed supported and simply supported two-way RC slab. Six separate specimens were casted for both end condition of different thickness, sizes and for different loads.

USE OF PLASTIC IN A CONCRETE TO IMPROVE ITS PROPERTIES

IJAERS/Vol. I / Issue III/April-June, 2012/109-111

Authors: Raghatate Atul M.

ABSTRACT
Plastic bags which are commonly used for packing, carrying vegetables, meat etc creates a serious environmental problem. Plastic bag last in environment up to 1000 years because of plastic bag last so long the number of plastic bag accumulated increases each year. Disposal of large quantity of plastic bag may cause pollution of land, water bodies and air.
The proposed concrete which is made up by adding plastic in concrete may help to reuse the plastic bag as one of the constituent’s material of concrete, to improve the certain properties of concrete. The properties of concrete containing varying percentages of plastic were tested for compressive strength and Split tensile strength and shows that an appreciable improvement in tensile strength of concrete can be achieved by introducing cut pieces of plastic bags.

STUDY OF HYDRODYNAMICS OF HORIZONTAL SPIRAL COIL TUBE

IJAERS/Vol. I / Issue III/April-June, 2012/112-114

Authors: Deshpande , Pramod M. Dr. Dawande Shrikant D

ABSTRACT
Horizontal spiral coil tube is a compact coil in one plan. The hydrodynamics of such coil is unique since it is governed by its curvature ratio variation. As coil is developed in one plan it has innermost coil diameter and it increases as tube coil move outward. The curvature ratio depends on coil pitch. In this paper horizontal spiral coil tube (HSTC) is investigated for laminar flow region for flow through tube (Re less than 2100). The HST coil in copper is fabricated from copper tube of diameter 9.13 mm O.D.; HST coil of five turns in horizontal plane with pitch of ‘2d’ is developed and has curvature ratio (d/dc) varies from 0.22 to 0.065 as compared to constant curvature ratio in vertical helical coil. The hydrodynamic performance of HST coil is compared with vertical helical coil.
The various forces acting on fluid element in coil are viscous, buoyancy and centrifugal force; of which the centrifugal force is predominant and results in secondary flow. As fluid element move away from the centre degree of secondary flow get reduced mainly due to reduction in centrifugal force. This phenomenon also depends on the physical properties of fluid at a given temperature. These coils have an application as heat transfer surface in process applications.

DESALINATION BY MEMBRANE DISTILLATION

IJAERS/Vol. I / Issue III/April-June, 2012/115-121

Authors: Rahul P. Raut, K. S. Kulkarni

ABSTRACT
Worldwide, the average baseline consumption of fresh water is 300 liters per day per person which equals to around one hundred thousand liters of fresh water per person annually. The demand for fresh water in India will be tremendous, which will be required by the increased population. Almost 20% of the world's population is facing lack of access to safe drinking water. Water covers over 75% of the earth surface and saline water makes up 97.5% of this; however just 2.53% is fresh and potable, used for different purposes such as domestic, industrial and agriculture demands. Based on the latest figures from “World Water Development Report” more than 50 percent of the nations in the world will face water crises by 2025, however by 2050 about 75 percent of the world population will have a significant possibility of facing water shortages. The answer to these water challenges is to find or create new, alternatives, and inexpensive resources of fresh water. Traditionally dams and artesian wells have been used in order to provide fresh water; however the amount of water that can be produced in these ways is insufficient or unpredictable. Therefore creating a new source of potable water has been a significant issue worldwide. Desalination could hold the key for new fresh water resources.

MITIGATING PERFORMANCE DEGRADATION IN CONGESTED SENSOR NETWORKS

IJAERS/Vol. I / Issue III/April-June, 2012/126-130

Authors: Sandip B. Chavan, H K Sawant

ABSTRACT
In today’s world Wireless Sensor Networks are used in many industrial and civilian application areas. Maintaining Sensor Network is very cost-effective so sensors will be shared by multiple applications to gather various types of data. All the data generated in Sensor Network will not be equally important, some data may be important than other. Thus a differentiated data delivery is required in Sensor Networks for HP and LP data. To accomplish this task this system uses CAR and MCAR routing mechanisms whose main aim is to increase the delivery ratio of HP data and to increase the performance of the system in presence of congestion. So the scope of the system can be confined as the task of integration of the existing technology and proposed routing protocols to the maximum level possible so that it reduce the time and cost significantly and the system can be utilized and implied in the suitable way possible. System objective is to lessen the progressive performance failure in an overcrowded Sensor Networks using CAR and MCAR and increase the Delivery Ratio of High Priority Data. Use energy more uniformly in the deployment and reduce the energy consumed in the nodes that lie on the conzone, which leads to an increase in connectivity lifetime.

PERFORMANCE ANALYSIS OF CHAOTIC DS-CDMA WITH CSK MODULATION

IJAERS/Vol. I / Issue III/April-June, 2012/133-136

Authors: Laxmi Bhat and Dr.K.L.Sudha

ABSTRACT
Direct sequence-code division multiple access (DS-CDMA) technique is used in cellular systems where users in the cell are separated from each other with their unique spreading codes. In recent times DS-CDMA has been used extensively. These systems suffers from multiple access interference (MAI) due to other users transmitting in the cell, channel inter symbol interference (ISI) due to multipath nature of channels in presence of additive white Gaussian noise (AWGN). Spreading codes play an important role in multiple access capacity of DS-CDMA system. M-sequences, gold sequences etc., has been traditionally used as spreading codes in DS-CDMA. These sequences are generated by shift registers and periodic in nature. So these sequences are less in number and also limit the security. This paper presents an investigation on use of new type of sequences called chaotic sequences for DS-CDMA system. These sequences are generated by chaotic maps. First of all, chaotic sequences are easy to generate and store. Only a few parameters and functions are needed even for very long sequences. In addition, an enormous number of different sequences can be generated simply by changing its initial condition. Chaotic sequences are deterministic, reproducible, uncorrelated and random-like, which can be very helpful in enhancing the security of transmission in communication. This paper investigates the performance of chaotic sequences along with chaotic modulation in DS-CDMA communication systems using various receiver techniques.

EMISSION AND PERFORMANCE OF DIESEL ENGINE USING DIRECT INJECTION CNG WITH SPARK IGNITION ENGINE- A REVIEW

 

IJAERS/Vol. I / Issue III/April-June, 2012/155-161

  Authors: Uttam R.B.
 

ABSTRACT
The conversion of a single cylinder diesel engine to CNG fuelled SIDI engine has been performed with the intention of reducing harmful emissions. To do it, it is necessary to change the basic working cycle from compression ignition (CI) to spark ignition (SI), including mixture formation, ignition system and control system. A gasoline direct injection (GDI) injector and a spark plug were installed in the combustion chamber. The CNG was injected into the combustion chamber by the GDI injector and then ignited by the spark plug placed near the injector. The close arrangement of the injector and spark plug provided a stratified charge of CNG around the spark discharge position. Emission and performance tests on both the single cylinder diesel engine and the modified CNG fuelled SIDI engine has been carried out and analyzed.

  Authors: S. P. Nangare, R. S. Kulkarni
 

ABSTRACT
The continual growth of Indian industries steps up towards the best coincidence with world for globalization. The economic activities in our country over last four decades have resulted in continuous rise in demand for power in spite of phenomenal growth rate achieved by the power sector. Mainly all the thermal power projects are satisfying it and the considered opinion of the experts in our country that the power shortage is here to stay in foreseeable future. The growing energy demand and the steep depletion of fossil fuels have directed the engineers and technologists to explore the possibilities of developing alternative sources of energy particularly from conventional non renewable energy source, As per the study of present installed project capacities and proposed untapped energies we can forward for new approaches towards power in India. As per the above surveyed situation experts explore the power generation targets towards all sugar industries. So 1200 MW energy can be generated from burning the surplus bagasse for the production of steam to run the turbine generators. This method is technologically known as Co-generation. For the generation of surplus power there is continuous analysis required for the economical balance for input and output power. The system analysis and results are calibrated under one process known as Energy Audit. This recovers the wastage of power through steam & heat and non control of feed air Tapping it at each interval can generate surplus power for Maharashtra will produce around 600MW from all running sugar factories. this paper finally focuses on developing alternative source is a lengthy process, it is important that energy conservation in the existing plants which can have beneficial effects often in the short term be stressed to help in the transitional period. The potential benefits of conservation are substation and hence it needs all round efforts. Besides it can be an effective means of combating the energy shortages in the short term and reducing the gap between supply and demand.

IJAERS/Vol. I / Issue III/April-June, 2012/172-174

  Authors: Bhaumik Patel, Ashwin Bhabhor
 

ABSTRACT
In this study, the work is carried out to design of Piston of reciprocating air compressor with the help of MATLAB software. It can be seen that MATLAB gives the accurate result of design of piston and also reduce the time to design. Also the work is done to predict the temperature distribution on the surface of the piston. Because distribution of temperature will predict that actual condition of the piston during the operating conditions, so damage of the piston can be reduced before taking into operations. Also it is seen that in the flat topped piston the center of the crown is hottest and the outer edge cooler by 20 to 50°C and if the heat flux is higher so temperature at this point is also higher and it is quite difficult to reduce the temperature.

IJAERS/Vol. I / Issue III/April-June, 2012/175-177

Authors: Prof. P.A. Shirule, Ataur Rahman , Rakesh D. Gupta

ABSTRACT
Leaving the waste materials to the environment directly can cause environmental problem. Hence the reuse of waste material has been emphasized. Waste can be used to produce new products or can be used as admixtures so that natural resources are used more efficiently and the environment is protected from waste deposits. Marble stone industry generates both solid waste and stone slurry. Whereas solid waste results from the rejects at the mine sites or at the processing units, stone slurry is a semi liquid substance consisting of particles originating from the sawing and the polishing processes and water used to cool and lubricate the sawing and polishing machines. Stone slurry generated during processing corresponds to around 40% of the final product from stone industry. This is relevant because the stone industry presents an annual output of 68 million tonnes of processed products. Therefore the scientific and industrial community must commit towards more sustainable practices. There are several reuse and recycling solutions for this industrial by-product, both at an experimental phase and in practical applications. These industrial wastes are dumped in the nearby land and the natural fertility of the soil is spoiled. The physical, chemical and mechanical properties of the waste are analyzed.

IJAERS/Vol. I / Issue III/April-June, 2012/184-187

Authors: Kiran D. Parmar, Kiran A. Patel, Dinesh D Mevada

ABSTRACT
This paper presents the guideline in thermal analysis for skirt to dished end joint of pressure vessel. Pressure vessel in which gases of high pressure and temperature are admitted through nozzle connections to shell to a dished end. So by these loading (internal pressure and temperature) there is several cracks/failure are developed in skirt dished end joint. The examples of crack/failure of skirt dished end joint are: cracking due to internal or external load, cracking due to lack of penetration, cracking due to chemical attack. In order to minimize the engineering effort on these systems it is desirable to develop standard “maximum” loads for skirt dished end joint configuration by Finite Element analysis approach. So for designing the pressure vessel stresses should have to be reduced. By using a proper design method and analysis there may be stresses developed parameters are find out. After analyzing by finite element method (FEM) the stress parameter are find out which should be consider as a maximum parameter for these one and it can be reduced by optimization. After optimization reduce the stresses of this joint due to change the weld size of skirt to dished end joint and also increase the life of pressure vessel.

IJAERS/Vol. I / Issue III/April-June, 2012/188-191

Authors: Vilas C. Renge, Pravin M. Dawale

ABSTRACT
Aconitic acid is a naturally occurring acid being present in Aconitum and other genera of plants, including beet roots and sugar cane. Being an unsaturated acid (carbon-carbon double bond) it can exist in two geometric forms, the trans isomer (1,2,3-propenetricarboxylic acid, C6H6O6) and the cis isomer. [1] The use of aconitic acid in the preparation of plasticizers and wetting agents. Aconitic acid is also used as an antioxidant, and is used in organic synthesis and as a flavoring agent. Reactive extraction is a promising method to recover carboxylic acid. So there is need for a extractant and diluent or a combination of extractants and diluent that can recover acid efficiently. Present study focuses on reactive extraction of Trans-aconitic acid using tri-n-butyl phosphate in n-Butanol and 1-Decanol. Reactive extraction with specified extractant giving a higher distribution coefficient has been emerged as a promising technique for the recovery of acids. [2] For the design of extraction process, equilibrium data of extractant is required to select a proper extractant for reactive extraction. On the basis of higher distribution coefficient and equilibrium complexation constant, the best combination of diluent extractant is suggested. The values of distribution coefficient using 20% TBP (KD=2.03) & 40%TBP(KD = 6.14) for n-Butanol and for 1-Decanol using 20% TBP(KD=1.27) & 40%TBP(KD=4).

Authors: Dinesh D.Mevada, Ketan B.Patel, Bhargav M.Chavda

ABSTRACT
Crack gas drier is one type of pressure vessel type device, it is used for drying process of ethylene, propylene gas or other many products like molecular sieve may be used. Here by using crack gas drier at different application it should be operated under different phases of operation like adsorption to regeneration. Drier operating from this condition in which temperature and pressure are changes within time in different phases of operation so under this changing condition there is crack or failure are induced due to fluctuation of temperature and pressure. This fluctuation of temperature or pressure is called transient period. In this transient period cracks or failure are induced which can reduce the life of drier. So for long life of drier these cracks or failure should be reduced by proper design method. Here in this paper by which process the cracks or stresses should be reduced are described.

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

ABSTRACT
Externally Reinforced /bonded fibre reinforced polymer (FRP) composite laminates have been successfully applied to reinforced concrete (RC) beams and other structural elements for the purpose of increase load carrying capacity of such elements. ACI 440 2R-08 and ISIS CANADA has given the guideline for design of Externally Reinforced /bonded FRP laminated beam. The philosophy behind both aforementioned methods is same; however, in ISIS code the design strain is not limited up to debonding failure, existing substrate strain not deducted for effective strain of fibre and the strength reduction factor are different than ACI method to find out the Strength of beam. Therefore, an attempt has been made in present work to compare the steps and resisting moment of ER-CFRP laminated beam by both methods.

ABSTRACT
The world is facing a great problem of energy crises, because of overuse of conventional fuels in automobiles, power generation and various thermal applications. Imposition of emissions norms by government regulating bodies to reduce environment pollution lead to the search for cleaner burning fuel. Wood gas is expected to play an important role in meeting the existing gap between the energy supply and energy demand, particularly in rural areas, in the present context of energy crises. The technology of Biomass gasification has existed from more than seventy years. Subsequent to World War II, the technology didn’t gain popularity. It is reported that Europe exploited the gasification technology and its use in IC engine. In American as well as Indian Sub continental a work is going on related to Producer gas IC engine. In the present paper an attempt is made to study the viability of waste biomass as an alternate source of fuel, its scope and limitation of gasification process. Also Design of Gasifier and its accessories and fabrication process of the gasifier. In the current research work, the downdraft gasification system is developed in aim of producing a consistent quality of Producer gas with less tar content. The gasifier system is developed which consists of Reactor, cyclone, filter and blower etc to supply producer gas at a rate such that a power of 3.74 kW is developed by burning the gas. The gas produced in the gasifier is a clean burning fuel having heating value of about 950-1200 kcal/m3. Hydrogen (18-20%) and carbon-monoxide (18-24%) are the main constituents of the gas.

SIMULATION ANALYSIS AND COMPARISON OF DSDV AND AODV ROUTING PROTOCOLS FOR MANET

IJAERS/Vol. I / Issue III/April-June, 2012/ 220-222

Authors: Neetu, Parveen Kumar

ABSTRACT
Mobile Ad hoc Networks (MANET) is a collection of wireless mobile nodes that communicate with each other without centralized control or pre established infrastructure. The mobile nodes can change their positions in such a manner that the interconnections between the nodes are changing on continual basis. In order to make communication possible within the network, a routing protocol is needed to discover the route between the nodes. Mobile Ad hoc Networks due to their characteristics put some extra requirements on the routing protocols such as, distributed control management, on demand operation, energy efficient approach and limited packet size. Numerous routing protocols have been proposed to make the communication possible within the MANET. All the routing protocols are divided into three categories such as Table Driven, on demand and Hybrid routing protocols. In this paper we analyze and compare DSDV (Table Driven) and AODV (On demand) routing protocols for MANET using NS-2 under random way mobility.

“EFFECT OF EXHAUST GAS RECIRCULATION (EGR) ON NOx EMISSION FROM C.I. ENGINE” - A REVIEW STUDY

IJAERS/Vol. I / Issue III/April-June, 2012/ 223-227

Authors: Harilal S. Sorathia* , Dr. Pravin P. Rahhod and Arvind S. Sorathiya

ABSTRACT
Internal combustion engines are established as the main power source for the automobile vehicles. At present emission norms becomes strict for any I.C. Engine. The main pollutant are CO, HC, NOx, PM, soot, etc from which NOx are one of the most harmful component. It is possible to limit the negative effect of NOx on the environment by various methods like exhaust gas recirculation (EGR), catalyst and water injection. The aim of this work is to review the effect of exhaust gas recirculation (EGR) to reduce the NOx emission from tailpipe of homogeneous charged C.I.engines. Cooled exhaust gas recirculation (EGR) is a common way to control the NOx generation in engine cylinder. It was found that adding EGR to the fresh air charge to homogeneous charged engines will beneficial to reduce the NOx emission substantially. Substantial reductions in NOx emission are achieved by previous investigators with 10% to 30% EGR. However, EGR has other effects on combustion and emission production that are increase of intake charge temperature, delay in heat release, decrease of peak cylinder temperature and decrease in O2 concentration in cylinder charge and decrease the air-fuel ratio.

DESIGN OF FRP LAMINATED COLUMN USING IS STRESS BLOCK-PARAMETERS

  IJAERS/Vol. I / Issue III/April-June, 2012/228-231                                                     

Authors: Dr. N. K. Arora, Reshma H. Parmar

ABSTRACT
It is now well known that both strength and load carrying capacity of concrete compressive members can be greatly improved by using fibre reinforced polymer sheets. 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 derive equation for FRP laminated column under axial compression and uniaxial bending as per IS 456-2000.

ABSTRACT
A sustainable transport system must provide mobility and accessibility to all urban residents in a safe and environment-friendly mode of transport. The rapid growth in the number of motor vehicles has resulted in severe traffic congestion and air pollution in many cities of the country. Bus rapid transit (BRT) is a term applied to a variety of public transportation systems using buses to provide faster, more efficient service than an ordinary bus line. The goal of these systems is to approach the service quality of rail transit while still enjoying the cost savings and flexibility of bus transit so the city can be self sustainable.
Ahmadabad has become the first city in South Asia to receive award for sustainable transport system. It has bagged for successful implementation of Bus Rapid Transit (BRT) system. This Paper examines the impact of BRT System on Ahmadabad’s transport sector and the changes that can be brought about by introduction of BRT System in other cities. BRTS Ahmadabad has improved access for local riders and advanced public transportation systems while reducing the environmental impacts of transportation. Moving people quickly, at a low cost, with reduced greenhouse gases and air pollutants helps cities grappling with rapid growth, congestion and environmental concerns.

DRIVING HIGH POWER LED

IJAERS/Vol. I / Issue III/April-June, 2012/242-244                                                               

Authors: Srushti P. Soni

ABSTRACT
The electrical supply used to drive LED Lighting is often with a series resistor to attempt to prevent the lighting from being damaged by variations in supply voltage. LEDs are essentially current driven devices. If a constant current electrical supply is maintained the intensity of LEDs is very stable and there is much less variation in output intensity due to temperature. LEDs are extremely sensitive to changes in voltage, resulting in large changes of intensity. Even a very small change, such as10mV, can result in a doubling of intensity. The main methods that are used till today are to provide dimming for LED’s from a switch mode LED driver are pwm dimming and analog dimming. The efficiency to produce colour is 70-75%.The driving method used here is by using Mosfet and trying to achieve 85% of efficiency and production of true colours

Authors: Mali Sanjay D, Dr. Mehta N S

ABSTRACT
In this paper presents energy and exergy analysis method for thermal power plant and analysis carried out on 125MW coal base thermal power plant. The increasing demand of power has made the power plants of scientific interest, but most of the power plants are designed by the energetic performance criteria based on first law of thermodynamics only. The real useful energy loss cannot be justified by the fist law of thermodynamics, because it does not differentiate between the quality and quantity of energy. Energy analysis presents only quantities results while exergy analysis presents qualitative results about actual energy consumption. In this analysis shows exergy efficiency is less at each and every point of unit equipments. Also presents major losses of available energy at combustor, superheater, economiser and air-pre heater section. In this article also shown energy exergy efficiency, exergy disctructon and energy losses comparison charts.

Authors: Rupali Jillawar

ABSTRACT
The architecture of the proposed DAC is discussed in details along with its low power and high linearity performance. The DAC architecture based on the R-2R ladder topology analyzed in terms of power consumption. The proposed DAC topology maintains the conventional ladder’s performance in speed and power dissipation without requiring large area for its implementation. Analog to digital converter for low power, high-speed flash ADCs are investigated. The ADC and DAC both are implemented in a 45nm CMOS/VLSI technology. Hence we conclude that the flash based ADC and R-2R based DAC seems to be a good choice with respect to area, efficiency and speed.

ABSTRACT
A watermarking scheme that discourages video piracy through the prevention of video playback is presented. In this method, the video is watermarked so that it is not permitted to play if a video player detects a watermark that is not extracted properly. Procedure takes the advantage of the properties of compression techniques like Robust Discrete Wavelet Transform and Singular Value Decomposition to provide Imperceptibility, Compression and Robustness to the created watermark which can withstand intentional attacks such as frame dropping, frame averaging and geometric distortions like rotation, scaling, cropping and lossy compression. The proposed work also uses Torus AutoMorphism, a scrambling algorithm for ensuring security. The objective of the scheme is to exploit the characteristics of the compression techniques and the algorithm for the creation of a robust watermark which is then used for making a video secure. This paper proposes an innovative, invisible watermarking scheme for copyright protection of digital content with the purpose of defending against digital piracy.

ABSTRACT
The main objective of this research work is the preparation of activated carbon by using Mahua oil seeds cakes which is a waste remain after the extraction of the mahua oil from the seeds by the method of Sulphuric acid (H2SO4) chemical activation. The mahua oil is used as a feedstock for biodiesel preparation and also has some medicinal use and the cake is a waste which is thrown away with no further use or used as cattle feed, thus this can be used as a feed stock for the preparation of activated carbon. The characteristics and surface area of the prepared activated carbon were investigated. The experiments were carried out with carbonization temperature varied from 400°C to 550°C. The results show that in all cases, increasing the carbonization temperature the yield decreases. It was found that the specific surface area of activated was at a maximum value (about 219.37 m2/g) at carbonization temperature of 500°C and carbonization time 2.0 h .The XRD analysis shows that the phase change from amorphous to crystalline form has been taken place.

Authors: Tapre A.R. and Jain R.K.

ABSTRACT
Banana (Musa sp var ‘Robusta’) of three advanced stages of maturity i.e. stage 5, 6 and 7 were analysed for their physic-chemical and mechanical properties. Fruits were treated with 500 ppm ethrel solution and kept for ripening under controlled conditions at 20±1 °C and maturity stages were selected on the basis of standard colour chart. As the ripening progressed, various physical changes observed in fruit such as increased in pulp to peel ratio, decreased in intensity of greenness of peel and also polyphenol oxidase activity decreased. Mechanical properties decreased significantly from stage 5 to stage 7. A significant difference (p ≤ 0.05) in firmness was found at different stages of ripeness of bananas. A similar trend was observed for other mechanical properties viz. cohesiveness, chewiness, fracture force and stiffness during the different stages of ripening. Moisture content, titratable acidity, pectin content, total sugar and TSS of pulp showed increasing trend from stage 5 to stage 7 whereas starch content progressively decreased during ripening.

ABSTRACT
The purification of waste water from various industrial processes is a world wide problem of increasing importance due to the restricted amounts of water suitable for direct use, the high price of the purification and the necessity of utilizing the waste products. Maintaining the drinking water quality is essential to public health. Although various water treatments is a common practice for supplying good quality of water from a source of water, maintaining an adequate water quality throughout a distribution system has never been an easy task.
Municipal, agricultural and industrial liquid or solid wastes differ very much in their chemical, physical and biological characteristics. The diverse spectrum of wastes requiring efficient treatment has focused the attention of researchers on membrane, ion-exchange and biological technologies. The most effective and ecological technological systems developed during the past 20 years are as a rule based on a combination of the chemical, physical and biological methods. Anaerobic digestion, anaerobic filters, lagoons, activated sludge and trickling filters have all been successfully applied to the treatment of distillery wastewater. Membrane and membrane separation techniques with immobilized microorganism or enzyme have very significant role in treatment of distillery wastewater.

ABSTRACT
In general, Pile groups are one particular type of deep foundation commonly used for large structures. It is quite complicated to analyze pile groups for the lateral loading. This paper presents the analytical studies on the lateral behavior of the pile group foundations for different group configurations subjected to lateral load. In this study, used same number of piles with different four pile group configurations (i.e.12x3, 6x6, 9x4 and 4x9 pile groups) with four value of spacing (i.e. 2D, 3D, 4D and 5D) and four different value of modulus of elasticity of soil (5000, 10000, 15000 and 20000kN/m2). Results of the influence of group configuration, pile spacing as well as modulus of elasticity of soil is discussed in terms of the displacement of the group and stresses in the soil. It can be observed that, the spacing of the pile group and the modulus of elasticity of the soil are largely affected on the lateral pile displacement and stresses in the soil for same amount of lateral load.

Authors: Ayazhussain M. Jabar, H. S. Patel

ABSTRACT
As known from very upsetting experiences, elevated water tanks were heavily damages or collapsed during earthquake. This was might be due to the lack of knowledge regarding the proper behaviour of supporting system of the tank again dynamic effect and also due to improper geometrical selection of staging patterns.Due to the fluid-structure interactions, the seismic behaviour of elevated tanks has the characteristics of complex phenomena. The main aim of this study is to understand the behaviour of supporting system which is more effective under different earthquake time history records with SAP 2000 software. Here two different supporting systems such as radial bracing and cross bracing are compared with basic supporting system for various fluid level conditions. For later conditions water mass has been considered in two parts as impulsive and convective suggested by GSDMA guidelines. In addition to that impulsive mass of water has been added to the container wall using Westergaard’s added mass approach. Tank responses including base shear, overturning moment and roof displacement have been observed, and then the results have been compared and contrasted. The result shows that the structure responses are exceedingly influenced by the presence of water and the earthquake characteristics.

ABSTRACT
Volume change is one of the most detrimental properties of concrete, which affects the long-term strength and durability. The important factors that contribute to the cracks in floors and pavements is that due to shrinkage. It is difficult to make concrete which does not shrink and crack. Efforts are made to reduce the shrinkage and shrinkage cracks. The main objective of this experimentation is to study the shrinkage properties of concrete containing hybrid fiber. The percentage of monofibers like steel, polypropylene, GI, HDPE, and percentage of hybrid fibers like (steel+ polypropylene), (steel+ HDPE), (steel+ GI) used in the experimentations were kept constant (by volume fraction). The experimental results indicated that the hybrid fiber reinforced concrete achieves reduction in the shrinkage cracks in concrete compared with their corresponding mono fibers.

Authors: Tajinder Singh, Rajeev Bedi

ABSTRACT
Image de-noising means to remove the unwanted signals from the image and restore it as the original image. Wavelets transform provides us the methods for image de-noising. As we know that the De-Noising of Images Corrupted by different noise is a major problem in Digital Image Processing. The wavelet transform has been a powerful and widely used for Image De-noising. For this purpose Wavelet thresholding method which is a signal evaluation method are used. Wavelet thresh holding with uniform threshold has shown some success in de-noising. Wavelet transforms enable us to represent signals with a high degree of sparsely. This is the principle behind a non-linear wavelet based signal estimation technique known as wavelet de-noising. In this paper we explore wavelet thresholding techniques for de-noising of images we describes that how these techniques helps us to remove the noise from digital images. Wavelet de-noising attempts to remove the noise present in the signal while preserving the signal characteristics, regardless of its frequency content.

ABSTRACT
Many marine superstructures and liquid cargo containers are made of aluminum composites due to its low weight and acceptable strength. These series are highly suitable in various marine structures, machinery and port buildings. It is very imported to study effect of corrosion on degradation of mechanical properties. The objective of this work to study the effect of seawater on mechanical properties of silicon carbide particle reinforced aluminum alloy composites with 5, 10 and 15% as well as aluminum alloy degraded by seawater solution were examined by tensile tests. The samples were degraded in the seawater for 10 to 90 days of interval of 10 days. It was observed that the surface observation of the corrosively degraded samples were degraded by pitting around intermetallic compounds and SiC particles while corrosive degradation of the sample was caused by synergy effect of pitting and intergranular corrosion. The mechanical strength of the Al alloy was lower than that of the composites. Reduction of ultimate tensile strength was greater in the Al/SiC than in the Al in the case of the same condition. The result to analyze the experimental data regressively showed that reduction of tensile strength proportional to sea water exposure duration.

UNCERTAIN DETERIORATION OF NODE ENERGY IN MANET THROUGH TRUST BASED SOLUTION

IJAERS/Vol. I / Issue III/April-June, 2012/319-324                                     

Authors: Shilpa Bade, H K Sawant

ABSTRACT
A mobile ad hoc network is a group of mobile wireless nodes which communicate with one another without any fixed networking infrastructure. As communication occurs in groups, multicasting is an efficient way to deliver the information to a group. Routing protocols generally establish the shortest path based on the number of hops between the source and the destination. In MANET, the routing protocols have to route the packets depending on the MANET constraints such as battery power in addition to the shortest path. The limited battery supply to mobile node in MANET forces the routing protocols to utilization of power and maximizes the network life time. Energy is consumed in MANET during the transmission and reception of data, propagation of control packets, retransmission and overhearing. We concentrate in reducing the power consumption during the transmission and reception of data. Each node in MANET transmits data with the maximum energy value of 0.283 watts regardless of the distance between the nodes. Also the mobile nodes expend some energy in transmission and reception of data. We have utilized the metrics received signal strength, link quality and the distance between the nodes to compute the energy required to transmit the data from a node to its neighboring node. The energy computed is involved in the selection of the optimal path which requires minimum energy to route the data from source to destination.

Authors: Asari Falguni P, Prof.M.G.Vanza

ABSTRACT
The paper presents the results of an analytical investigation of the seismic response of elevated water tanks using fiction damper. In This paper, the behavior of RCC elevated water tank is studied with using friction damper (FD). For FD system, the main step is to determine the slip load. In nonlinear dynamic analysis, the response of structure for three earthquake time history has been carried out to obtained the values of tower drift base shear and acceleration Time Period. These values are compared with original structure. Results of the elevated tank with FD are compared to the corresponding fixed-base tank design and indicate that friction damper is effective in reducing the tower drift, base shear, time period, and roof acceleration for the full range of tank capacities. The obtained results shows that performance of Elevated water tank with FD is better than without FD.
