Title : Fabrication of Catalytic Convertor for Automibile Authors : G.Balasubramanian, P.Balashanmugam, D.Karthikeyan
Abstract : Diesel power inevitably finds a very important role in the development of the plant’s economy and technical growth. In spite of their high thermal efficiency, one cannot ignore the fact about the effect of their exhaust, in the atmosphere. It is a well-known fact that the toxic gases emitted in diesel engines are less than the engines. Due to the high cost of petrol, diesel engines are more in use. Anticipating the use of diesel engines, even more in the near future; this system developed can be used to control the toxic gases, coming out of the diesel engines. These toxic gases are harmful not only to the atmosphere, but also to the human & animal race. The objective of this project is to design & fabricate a simple system, where the toxic levels are controlled through chemical reaction to the more agreeable level. This system acts itself as a silencer; there is no need to separate the silencer. The whole assembly is fitted in the exhaust pipe; it does not give rise to any complications in assembling it. This system is very cost effective and more economical. The rapid growth in the energy consumption at the individual level has given rise to a dramatic increase in both air and water pollution problems. The automobile is probably the most notorious source of atmospheric air pollution on a total mass basis. Under the Indian Conditions two and four wheelers have become the most popular mode of transport. In the present work catalytic converter was chosen for CI engine emission control, to reduce CO, HC and NOx emission. A catalytic converter has to be designed and introduced in the exhaust line of the CI engine. In the present work Kirloskar TV-I engine is chosen for emission control study using a catalytic converter. The objective of the catalytic converter is to reduce the cold start emission of CO, HC and NOx in the exhaust gas of the engine. The catalytic converter is made of stainless steel plate. The plate is coated with copper, Nickel and Chromium catalytic materials. These emission levels will be measured using the AVL exhaust gas analyzer and the results will be analyzed.

Title : Effect of heat treatment on the microstructure and mechanical properties of High Manganese Steel 15Mn2Cr1V Authors : Nguyen Duong Nam, Le Thi Chieu, Pham Mai Khanh, Pham Hữu Kien
Abstract : In this work, we want to propose the method to increase the abrasion of the High Manganese Steel (HMS) 15Mn2Cr1V, which is heat treated by the different processes, i.e. the HMS is intermediate heated and without intermediate heating treated before austenizing. The obtained experimental result reveals that with intermediate heating, the austenite is uniform, small size grain (level 6 according to ASTM) and no carbides at the grain boundary. The obtained hardness value is equal to 98 HRB and much larger than one for the process without intermediate at 6500C. The obtained average impact toughness is equal to 115 J.cm-2. This value is also larger than one for the process without intermediate (17 J.cm-2).

Title : Design Optimized Framework for Migrating a Legacy System to Cloud Environment Authors : C.Udaya Shankar, P.T.Ajith, N.Naveen Kumar, S.Pushpalatha
Abstract : Cloud computing have attracted more and more enterprises to migrate their legacy applications to the cloud environment because of its high-scalability, on-demand nature. Although the cloud platform itself promises high reliability, ensuring high quality of service and high reliability is still one of the major concerns, since the enterprise applications usually consist of a large number of distributed components. Thus, improving the reliability of an application during cloud migration is a challenging and critical research problem. To address this problem, we propose a reliability-based Reliability Optimization Cloud (ROCloud) and consider all the constraint factors such as cost, etc., to improve the application reliability by fault tolerance. ROCloud includes two ranking algorithms. The first algorithm performs ranking of all the components, for an application, that will be migrated to the cloud. The second algorithm ranks components for hybrid applications that only part of their components are migrated to the cloud. Both algorithms employ the application structure information as well as the historical reliability information for component ranking. Based on the ranking result, optimal fault-tolerant strategy will be selected automatically for the most significant components with respect to their predefined constraints. The experimental results show that the reliability of the application can be greatly improved by refactoring a small number of error-prone components and tolerating faults of the most significant components

Title : Design and Control of Multi Level Inverter with Single DC Source Authors : Agnihotram srinivas kumar , M.Sridhar
Abstract : In this project six rules for designing hybrid cascaded multilevel inverters with simplified supply and low switching losses have been derived. These design rules constrain the ratio between the dc voltages of the supplied cells and the dc voltages of the unsupplied cells. They allow one to design single- and three-phase inverters that can be operated either with staircase or with PWM. New configurations that increase the flexibility for choosing suitable switches. The concept of energy balance domain has been introduced to characterize the achievable operating modes and power factor.
Hybrid asymmetrical cascade multilevel inverters, they combine cells of different voltage ratings different topologies, or even combine switch converters with linear amplifiers. So, in this project mainly focused on the design and control of high-resolution, high-efficiency multilevel inverters with simplified dc power supplies. It introduces several rules for systematically designing the dc voltages of the cells, for which all unsupplied capacitor voltages can be regulated. Six classes of inverters are obtained covering single and three phase, staircase and pulse width-modulated (PWM) inverters.
New configurations of hybrid cascade multilevel inverters are obtained for each class. A double modulation strategy with two different frequencies is proposed that allows switching losses of PWM inverters to be reduced. Decoupled mechanisms are proposed for the total and internal energy balances. It is shown how to make the design robust by taking into account conversion losses and large dc-voltage imbalances in the design and control. The entire proposed system will be tested using MATLAB/SIMULINK.

Title : Performance Analysis of Lithium-Bromide Water Absorption Refrigeration System Using Waste Heat of Boiler Flue Gases Authors : B.Babu, G. Maruthi Prasad Yadav
Abstract : Vapor absorption refrigeration is a low grade thermal input device, which is mostly used along side with industries, which have high thermal waste and also simultaneously requires cooling parts of the plant. For air-conditioning in which refrigeration below 00c are not needed, an absorption refrigeration using lithium-bromide and water, has been successfully developed and has achieved great commercial success.
Owing to the threat of global warming due to high thermal disposal and to compensate the energy crisis, VAR is likely to gain immense prominence in near future. Main theme is to utilize the waste heat of the flue gases generated in thermal power stations. Before leaving these gases to the atmosphere through the chimney necessary mass of flue gases is by passed and is made to deliver it generator so as to run the vapour absorption refrigeration system there by conserving the energy.
The aim of the project is to perform analysis on absorption refrigeration system using lithium-bromide and water as refrigerant and to find out the influence of operating temperatures on the thermal loads of components and their co-efficient of performance. Finally come up with the operating conditions where it can run by effectively utilizing the waste heat of the flue gases.

Title : Promoting Appropriate Technology for Sustainable Development: Case of Agro-processing SMEs in Tanzania Authors : Jafari Mwanza, Bashira Majaja, Elias Erasto
Abstract : The present status of agro-processing SMEs in Tanzania is largely informal, under-performing and in need of considerable assistance to overcome barriers to its growth. Agro-processing SMEs use labour-intensive technologies to compensate for the lack of technical capacity in order to perform well. The strength of the Tanzanian agricultural sector lies in the ability of the farmers to produce high quality produce and products. This will only be possible through the use of appropriate technology right from the farming stage through processing to marketing. The transformation process of changing raw agricultural material to consumable value added product must require the use of appropriate technology in one form or another. In fact technology are the key to improving efficiency in agro processing and value addition industry to compete against imported produce from countries with developed industry. This paper focuses on how to promote appropriate technology and overcome barriers for sustainable development and growth of agro-processing SMEs in Tanzania. The discussion of the findings is based on the data collected from questionnaires and interviews which was administered to 120 Small-scale Agro-processing Enterprises in nine regions of Tanzania.

Title : Fertility and Its Proximate Determinants of Bangladesh Authors : Dr. Md. Roshidul Islam
Abstract : The study of determinants of fertility in a population is a complex process. While fertility behaviour influences population growth, which has consequences towards pressure on resources, employment situations, health and other social facilities, and saving and investment, such consequences, in turn, have great bearing on the socio-economic variables that affect fertility behaviour. The issues are further complicated because the factors that are perceived to influence fertility are highly interrelated. The conceptualization of the determinants of fertility involves a multitude of factors that vary greatly in the intensity and direction of force they exert on fertility. The study of the relationship of fertility levels to specific economic, social and cultural variables in the low as well as high fertility countries has “led to the hypothesis that for the most part the same factors which are thought to account for the decline of fertility in the low fertility countries are, in a reverse sense, also responsible for the continued high levels of fertility in the high fertility group” (UN, 1973).

Title : Assessment of the Global Solar Energy Potential at Auchi Area of Nigeria Authors : Ebunilo, P. O. B., Izah, L. A.
Abstract : This paper assessed the global solar radiation potential in Auchi area of Nigeria, for the period of January, February, March and April, 2014. Auchi lies between latitude 7014’ North and 7034’ North of the equator and longitude 6014’ East and 6043’ East of the Greenwich Meridian. The climate is subhumid and the average temperature is about 330C in the rainy season and about 420C in the dry season. Procedure employed involved the use of Hargreaves-Samani’s equation as a method of estimating solar radiation using minimum climatological data. The method or model makes use of recorded daily maximum and manimum temperatures for the four months while weather station parameters (sunset hour angle, extraterrestrial solar radiation, etc) were directly derived from the latitude of the area. The model provides a simple and low cost system for estimating solar radiations because it does not require expensive hardware for data processing nor information from neighbouring meteorological stations for spatial interpolation. The global solar radiation at Auchi area of Nigeria within the period of study exhibits monthly variation but an average or mean of 22.61MJ/m2/day was obtained for the four months. The information from the study conducted will go a long way to establish solar irradiation data on the area which will then form a baseline for any planned application of solar irradiation in the area, such as in the design of solar photovoltaic systems.

Title : Natural resource abundance and Structural Change: The Dutch disease in Algeria Authors : S.M. Chekouri, A. Chibi, M. Benbouziane
Abstract : This study investigates the evidence of the Dutch Disease in Algeria by observing the structural change in the Algerian economy since independence. The paper argues that the Dutch disease in Algeria may be hypothesised. The main justifications behind it are the relative deterioration of manufacturing and agricultural sectors, and the relative improvement of service sector and oil sector performance. Furthermore, the Algerian hydrocarbon exports still dominate the total exports and account for more than 98 percent of export receipts in the last fifteen years. Thus, the work in hand has given more consideration to the Dutch Disease explanations to the oil curse. However, recent studies have mentioned that institutions have a powerful explanation of the curse in oil rich countries.

Title : Control Strategy with Voltage Support Capability for Distributed Generation Inverter under Voltage Fluctuations Authors : B.Manmadha Rao, A.Tejasri
Abstract : This paper proposes a voltage controller under voltage sags based on the current scheme,which restores the dropped voltages to its continuous operation limits, Voltage sags are one of the main problems in transmission and distribution grids with high penetration of distributed generation.This paper proposes a voltage support control scheme for grid-connected power sources under voltage sags.
The control is based on the injection of reactive current with a variable ratio between positive and negative sequences. The controller determines, also, the amount of reactive power needed to restore the dropped voltage magnitudes to new reference values confined within the continuous operation limits required in grid codes.These reference values are chosen in order to guarantee low current injection when fulfilling the voltage support objective.Selected experimental results are reported in order to validate the effectiveness of the proposed control.
