ABSTRACT
Fuel consumption is an extremely important parameter for the automotive industry today. In engines the piston system is the largest source of frictional losses, accounting for about 30% of the total frictional losses, thus it is important to optimize. The lost caused by friction and wear is huge. There is about 30% power of automobile engine lost because of friction, 19% of the power loss is come from the piston ring-cylinder liner pair. This important pair of engine often damaged because of wear.
Lubricant film in an internal combustion engine (I.C. Engine) is an important factor in determining fuel economy and performance of the vehicle.

IJAET/ Volume IV/ Issue I/ Jan.-March.'2013/09-13

 

ABSTRACT
The aim of this paper is to provide an analysis on the relationship between Information Technology (IT) usage, CRM and performance of bank(state bank group) in Bhubaneswar, Odisha, India. Most of the banks in INDIA are geared for comprehensive banking solutions with extensive branch networks. Empirical data collection was done in the year 2011 and analyzed with the theoretical data. A sample of 18 branches was selected using the non-probability sampling technique. Perceptions of branch managers, staff members and customers were collected using a survey method. All 18 branches selected are of an equivalent grade according to the grading set by the bank. Three different types of questionnaires were designed for branch managers, branch staff and customers. Both structured and semi structured questions were included in the questionnaires with 7 point likert scale. Using bivariate correlation and linear regression, data analysis was done. The linear relationship between variables was measured by using Pearson’s correlation coefficient. The analysis suggested that IT usage has a positive linear relationship with financial performance and quality performance of bank branches. Bank performance was found to have a correlation with factors such as staff attitude towards IT usage, IT literacy level of bank staff and scope and complexity of the IT applications.

ABSTRACT
The investigation of the influence of corrosion–erosion wear parameters like normality of acid media, abrasive particle and reinforcement on corrosive-erosive of and Al/SiC metal matrix composites (MMC’s) using Taguchi technique. The slurry was made up of alumina of size 90-150m and proportion of 10, 20 and 30 wt %, while normality of H2SO4 is 0.01N, 0.1 N and 1N was added to create the corrosive conditions. Experiments were arranged to test the relationships among the corrosive-wear rate, concentrations of H2SO4 and alumina in the slurry, weight percent of SiC in the composite at constant erosion speed of 400 rpm and distance 3 km. Optimal levels of physical parameters and key media components were determined. The correlations were obtained by multiple regressions. Results show that % of volume abrasive particle has the highest influence (57.32) followed by normality (31.46) and wt.% of reinforcement (3.04). Finally, confirmation tests were carried out to verify the experimental results and scanning electron microscopic studies were done on the corrosive-wear surfaces.

IJAET/ Volume IV/ Issue I/ Jan.-March.'2013/27-30

 

ABSTRACT
The industrial revolution followed by the urbanization in temperate countries, concentrated people in very high density and added new sources of wastes. The disposal methods followed presently causes serious impacts on the environment and public health. Vermicomposting is being increasingly accepted as the most efficient and safe method for converting organic waste into plant food.
An experimental study was conducted to obtain vermicompost using partially decomposed organic wastes by using the Eudrillus euginea earthworm species. The process was carried out with the use of municipal solid waste to stabilize the feed composition. Water was added to provide the necessary moisture content. In this process the partially decomposed organic wastes was broken down and fragmented rapidly by earthworm, resulting in a stable, less toxic material which has a high economic value as a soil conditioner for plant growth. The castings was obtained within 30 days on the top surface which was collected, sieved, dried, tested and used as manure. The trial plants were planted in two different fields. The plants were ladies finger and fenu greek. The plants were grown with the addition of vermicompost in one field and natural compost in other field.
The result shows that the increased nutrient content was for organic wastes and better growth in the vermicompost added plants than the natural compost plants. This experimental study proves that the vermicomposting process can be employed to treat the wastes in an environmentally safe manner

ABSTRACT
To produce low cost concrete by blending various ratios of cement with hypo sludge & to reduce disposal and pollution problems due to hypo sludge it is most essential to develop profitable building materials from hypo sludge. To make good quality paper limited number of times recycled Paper fibres can be used which produces a large amount of solid waste. The innovative use of hypo sludge in concrete formulations as a supplementary cementitious material was tested as an alternative to traditional concrete. The cement has been replaced by waste paper sludge accordingly in the range of 0% (without Hypo sludge), 10%, 20%, 30% & 40% by weight for M-25 and M-40 mix. Concrete mixtures were produced, tested and compared in terms of strength with the conventional concrete. These tests were carried out to evaluate the mechanical properties like compressive strength up to 28 days and split strength for 56 days are taken. As a result, the compressive increased up to 10% addition of hypo sludge and further increased in hypo sludge reduces the strengths gradually. This research work is concerned with experimental investigation on strength of concrete and optimum percentage of the partial replacement by replacing cement via 10%, 20%, 30%, and 40% of Hypo Sludge. Keeping all this view, the aim of investigation is the behavior of concrete while adding of waste with different proportions of Hypo sludge in concrete by using tests like compression strength and split strength.

IJAET/ Volume IV/ Issue I/ Jan.-March.'2013/36-38

 

ABSTRACT
In the presented study, the effects of using dual- spark plug and variation of the spark plug location on the exhaust emissions of an SI engine operating in different conditions were investigated theoretically. A quasi-dimensional two-zone thermodynamic cycle model was developed for this purpose. CO2, CO and NO concentrations in the exhaust emissions were determined for each of operating condition. Obtained results showed that there are considerable effects using dual-ignition and varying spark plug location on exhaust emissions. Using dual-ignition decreases exhaust emissions especially by shortening flame travel length and minimizing combustion duration.

IJAET/ Volume IV/ Issue I/ Jan.-March.'2013/51-53

 

ABSTRACT
Vending machines are used to dispense small different products, when a coin is inserted. These machines can be implemented in different ways by using microcontroller and FPGA board. Here in this paper, we proposed an efficient algorithm for implementation of vending machine on FPGA board. Because FPGA based vending machine give fast response and uses less power than the microcontroller based vending machine. The FPGA based vending machine supports four products and three coins. The vending machine accepts coins as inputs in any sequence and delivers products when required amount is deposited and gives back the change if entered amount is greater than the price of product. It also supports cancel feature means a user can withdraw the request any time and entered money will be returned back without any product. The proposed algorithm is implemented in Verilog HDL and simulated using Xilinx ISE simulator tool. The design is implemented on Xilinx Spartan-3A FPGA development board.

IJAET/ Volume IV/ Issue I/ Jan.-March.'2013/54-57

 

ABSTRACT
Experiment involves study of change in mechanical properties as a result of post weld heat treatment of shaft & wheel assembly: a component of turbo charger. Processes involved are friction welding to assemble shaft & wheel, stress relief by heating and then induction hardening. During friction welding because of rapid friction, squeezing & solidification of weld joint under high mechanical force, stress introduced in shaft & wheel assembly which in turn reduces service life of component. To minimize the effect of this internal stress and to enhance strength, hence service life of component, it is heat treated. Later component is induction hardened to obtain desired hardness. All the parameters such as heating temperature, Maximum strength & Hardness required after heat treatment were all set taking into account service conditions of shaft & wheel assembly during working of turbocharger in an automobile engine. Strength testing using UTM, Hardness test using Rockwell scale, hardening depth using Nital Test was performed & results analyzed to confirm desired changes in mechanical properties.

Authors: Dr. Sunita M. Mahajan and Ms. Vaishali P. Jadhav

 

IJAET/ Volume IV/ Issue I/ Jan.-March.'2013/67-71

 

ABSTRACT
Various joining methods are used in distributed databases to reduce the amount of data transfer. While optimizing a distributed query, the main focus is on minimization of data transfer between sites. In previous work, we have seen how the semi-join helps to reduce the amount of data to be transferred. This paper gives another type of join called Bloom Join. Bloom Join which uses Bloom Filter which works better than Semi-Join, reduces amount of data transfer between different sites and performs efficient query processing. We have used a Hadoop framework which allows data storage and query processing in distributed databases. SQL query is converted into Map-Reduce jobs and then Hadoop framework is used to co-ordinate amongst data sites and also used to process the query on local DBMS.
