Abstract: Quality of Surface is an important factor to decide the performance of a manufactured product. Surface quality affect product performance like assembly fit, aesthetic appeal that a customer might have for product. The nominal surfaces of the object are represented by perfect straight line, perfect circles, round holes, straightness and absolute perpendicularity A variety of processes are used to make the designed parts. The characteristics of surfaces includes surface texture, surface integrity which is always related with manufacturing processes for maintain quality of surfaces. For better quality surface finish the main factor is surface roughness. The lower value of roughness gives higher surface finish for the manufactured product. Now in present scenario different processes like grinding, honing, super finishing, polishing, burnishing etc are used to reduce the value of surface roughness. Burnishing is one of the processes which majorly affect the surface roughness. In conventional machining processes the tensile residual stresses are induced on the surface of material, which reduces the fatigue strength of material, this can be prevented by inducing residual compressive stresses on the surface of material. Burnishing is a cold working process in which initial asperities are compressed beyond yield strength against load. The surface of the material is progressively compressed, then plasticized as resultant stresses reach a steady maximum value and finally wiped a superfine finish. The highly finished processes find the application in aerospace and aircraft industry.

Abstract: Particulate Matter (PM) is one of the major harmful substances in diesel exhaust gas. Technologies like the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC) have been positioned at the exhaust to reduce the quantity of harmful substances released to the environment. This paper highlights the factors that affect combustion in diesel engines and the potential of the introduction of electromagnetic field in the combustion chamber on the improvement of the diesel engine efficiency and reduction in the quantity of Particulate Matter (PM) produced.

Abstract: Auto rickshaws are tiny, three-wheeled vehicles which are used extensively in many Asian countries for transport of people and goods. The vehicles are small and narrow allowing for easy maneuverability in congested Asian metropolises. In Bangladesh, auto rickshaws are commonly used as taxis. This is due to the use of an engine, typically a 2 or 4 stroke, with almost no pollution control. Usually fuels are used in auto rickshaws. But a few years ago some auto rickshaws have been imported from china which is run by battery. The numbers of battery powered auto rickshaws are increasing day by day. This research paper includes comparison study of battery operated easy bike with CNG (Compressed Natural Gas) operated auto rickshaw in terms of cost (operating cost, manufacturing cost, maintenance cost), user friendly and environmental issue.

Abstract: This study was undertaken in order to highlight and compare the curricula of the different Library Schools in the tertiary institutions, South East, Nigeria. This is a descriptive survey, using a checklist (the minimum academic standards provided by the different regulatory bodies – NUC and NBTE). All the ten Library Schools in South-East, Nigeria, were used for the study. The results of the study reveal that there are no uniformity and conformity in the curricula run in the Universities, but there are uniformity in the Polytechnics curricula. In spite of the uniformity & conformity with its regulatory body's minimum standard, the Polytechnic curriculum is not suitable for registerable status as Librarians to be accorded to its products. The regulatory bodies rely heavily and wholly on professional bodies to provide their different professional and academic programmes standards. The NLA and LRCN are not doing much yet in the area of standardization and harmonization of the curricula so as to train Librarians/Information Scientists of this 21st century.

Abstract: Public transport plays an important role in providing easy and affordable accessibility and mobility for dwellers in a city. This demand for transportation is brought about by the increased population of connecting nodes, cities, the rural-urban migration, and the scope for socio-economical facilities i.e. better opportunities for jobs, health facilities and educational scope etc. thus the economic viability of the people which leads to an increase in the usage of private vehicles. Dhaka is an over densely populated city and its transport system comprised of many different modes of travel – both motorized and non-motorized - using the same road space – resulting in a high level of operational disorder, that significantly diminishes the efficiency and effectiveness of the existing transport uses. Dhaka is experiencing lots of traffic congestion and a great lack of traffic management. There has been no study dedicated to overcome the situation. Therefore, there is an urgent need to introduce a well-organized, properly scheduled rapid mass transit system minimizing the existing deficiencies. In this paper, an attempt has been made to identify the deficiencies of existing public transport system to put forward for an appropriate rapid mass transit system to recover the huge demand. An overview of the existing modes of travel and operation characteristics has been described. Finally, some proposals for integrated hierarchical transport network options are highlighted with the context of prevailing land use and transport characteristics, socio-economic context of Dhaka Metropolitan city. The findings of this research help planners and decision makers to optimize the investment in transport infrastructure.

Abstract: The shoulder of friction stir welding tool influences properties of welded or processed zone from appearance to internal microstructural features. The main function of the tool shoulder is the control of work piece material towards the probe by rotational flow generated by the tool and the force distribution under the shoulder generating required temperature and hydrostatic pressure to ensure proper containment and consolidation in forming defect free weld. The efficiency of the shoulder in this regard may be evaluated by the surface appearance and uniformity of the weld bead. In the present study, the images of weld bead surface of friction stir welded specimens produced using different process parameters is analyzed using image processing technique. The images are digitally processed and analyzed by defining suitable region of interest along good and defect weld region based on X-Ray radiography results of friction stir welded specimens. The line profile plot along the weld line and contour plot of weld bead images are plotted using MATLAB. The variation in the slope of line profile plot and appearance in the contour plot along good and defect weld regions are observed which enables to assess the quality of weld using image processing.

Abstract: This paper presents results of the Electrochemical Machining (ECM) process, which was used to machine the SS AISI 202. Specifically, the Material Removal Rate (MRR) and Surface Roughness (SR) as a function of ECM were determined. The experimental work was based on the Taguchi approach of experimentation and table L32 was used. Furthermore, a theoretical and computational model is presented to illustrate the influence parameter variations in results. In addition to this the influence of independent parameters such as time of electrolysis, voltage, current, concentration of electrolyte, feed rate and pressure upon the amount of material removed and SR. The results indicated that MRR was remarkably affected by variation in current and Surface Roughness decreased with increase in current. Hence, it was apparent that irregular MRR was more likely to occur at high currents. The results showed that MRR increased with increasing electrical voltage, molar concentration of electrolyte, time of electrolysis and feed rate. However, the time of electrolysis was the most influential parameter on the produced surface finish.
