A Study on the Consumer Adoption of Electronic Banking Technology with reference to Ethiopian Banking Sector

This research paper tries to find out the reasons why costumers’ are not using e banking facility , study the awareness level of various secure transaction methods and study the difference between proportion of respondents to whom bank educates and proportion of respondents to who bank does not educate about the e-banking services being offered. The administrative management of the bank has a lot of scope of action from the findings of the research.

A Design of Thermoelectric Cooler and Optimization | IJSTE JOURNAL VOL 2, ISS 6

A Design of Thermoelectric Cooler and Optimization

Design, analysis and optimization of a thermoelectric refrigerator was carried out in this work the systems use thermoelectric "peltier" refrigerators (thermoelectric modules) to produce cooling or heating. The design calculation are find the performance curve of the thermoelectric module with the purpose of is find by simulation. Simulation results were compared with the practical data. The system simulation shows that exist a cheapest heat sink used for the thermoelectric refrigerator. the thermoelectric refrigerator with an air-cooled heat sink with thermal resistance 0.2515°C/W. Comparison was done between Bismuth telluride (Bi2Te3) and Antimony telluride(Sb2Te3) for the thermoelectric module. It was found that the bismuth telluride (Bi2Te3) due to its low thermal conductivity and high See back coefficient at room temperature has higher figure of merit (Z) and thus performed better as compared to Antimony telluride. The design be capable of be ready either on basis of the highest value of the cooling capacity, or on the basis of the most excellent heat sink technology existing.

Experimental Investigation Work of Diesel Engine by Developing Combustion Chamber Geometry | IJSTE JOURNAL VOL 1, ISS 12

Experimental Investigation Work of Diesel Engine by Developing Combustion Chamber Geometry

Morden internal combustion engines must meet high emission standard including better performance and fuel economy. An increased diesel engine population has created pressures on controlling diesel PM and NOx emissions. EGR to control NOx emissions by reticulating exhaust gases back into the combustion chamber to be burned a second time, thereby reducing emissions associated with health risks and also change in combustion chamber geometry to reduce exhaust emission. Major emissions from a diesel engine are NOx, SOx, CO and particulate matter (PM).amongst these pollutants CO and Sox and some quantity of particulate matters are reduced by some after treatment methods, improve combustion chamber geometry etc.

Behaviour of Reinforced Concrete Beam with Cement Replaced By GGBFS and Fine Aggregate Replaced By GBFS | IJSTE JOURNAL VOL 2, ISS 4

Behaviour of Reinforced Concrete Beam with Cement Replaced By GGBFS and Fine Aggregate Replaced By GBFS

The present study focuses on the structural behaviour of reinforced concrete beams with Ground Granulated Blast Furnace Slag (GGBFS) and Granulated Blast Furnace Slag (GBFS). Ordinary Portland Cement was replaced with GGBFS and fine aggregate is replaced with GBFS in M40 grade concrete of water cement ratio 0.4. Cement was replaced with GGBFS for various percentages such as 0%, 25%, 30%, 35%, 40%, 45%, 50%, and 55%. The optimum cement replacement was obtained at 45%. Replacements for fine aggregates are 0%, 25%, 30%, 35%, 40%, 45%, 50%, 55%. The optimum for fine aggregate replacement was found to be 45%. In the next stage a combination replacement was carried out i.e. cement replacement is fixed at 45% and fine aggregate replacements were done for various percentages (0%, 25%, 30%, 35%, 40%, 45%, 50%, 55%). In this combination replacement the optimum was obtained at 30% fine aggregate replacements. These optimum replacements for cement and fine aggregates were used to cast beam specimens. These beams were tested under two-point loading to study the flexural behaviour. After conducting flexural strength test the parameters such as first crack load, yield load, displacement ductility index and curvature ductility index were studied and compared with control beams. The results were found to be comparable with control specimens.
