Abstract: During earthquake, the building undergoes various random motions of the ground at its base, which induces inertia forces in the structure. Different types of irregularities are considered in the building viz. Mass irregularities and geometric irregularities in urban India, which are subjected to several types of forces. Earthquake load mainly induce lateral forces which causes lateral displacement of the structure. The effect of gravity load acting on the structures lateral displacement is called the P-delta effect. Due to P-delta effect, geometric nonlinearity induces in the building which creates additional moment and shear. It is generally observed that the regular buildings have a dominant fundamental results participation in their seismic responses and as the irregularity increases the contribution of it. Hence, In the present study, modelling and analysis of Regular and Irregular RCC building is carried out in SAP2000V16 considering P-delta effect using Time history analysis. Various parameters such as base shear, storey drift and overturning moment are obtained. It is found that p delta effect in building needs to be considered and controlled..

Abstract: In this project development of Micro gas turbine with three different materials are tested and designed using Autodesk inventor and Autodesk nestron software. Generally micro gas turbine is a size so they are compactable and easy maintains compared to large turbines. in this project three different materials like Aluminium and Stainless steel and Tiatanium are used for turbine blade .the solid model is created using Auto desk inventor software and analysis is is done by using Autodesk nestron Software. the micro gas turbine are few rotating parts so the frictional losses and pollution is less compared to other power generating elements. the micro gas turbine are quicker to respond to output power requirements and also more efficient than other machine elements. Micro turbine being small in size as compared to large turbine, such that less weight which reflects on pressure ratio, low cost and easy maintenance.

Abstract: This article's main function is to analyze the possibilities and applications of numerical-computational analysis (in this case, the Abaqus software) to drawing considering both problem solving and project definition related to the manufacturing process. Therefore, this work starts with a comparison between analytical and numerical analysis of the process, mentioning the advantages and disadvantages, as well as the indicated application of each; and with a presentation of the Abaqus software potential and limitations. Next, a theoretical case study is proposed to better analyze this problem, testing the differences between the two methods (analytical and computational) of a specific problem solving in drawing process. The results are, finally, compared generating further conclusions.

Abstract: The objective of this study is to evaluate the effect of adding Road bond EN-1 to the asphalt cement and their asphalt mixtures properties, and the long term performance. The variables considered are the effect of adding different ratios of EN-1 to suej 60/70 Asphalt cement properties . The added ratios are 0.3, 0.4 and 0.57 by weight for 60/70 A.C. For asphalt mixtures, the variables considered are the effect of the above modified asphalt cement on Marshall Properties. The results of this study indicate that the addition of EN-1 to suez A.C and its asphalt mixtures at all ratios improved all properties. The addition of EN-1 to seuz A.C improves its thermal characteristics by increasing its penetration index. Increasing the percentages of EN-1 increases stability and Marshall Stiffness and decreased the flow of Asphalt concrete mixtures.

Abstract: In this research, three different tool geometries (pinless, cylindrical and square pin) were developed to study the effect of friction stir processing (FSP) tool geometry on microstructure and mechanical properties of metal inert gas (MIG) welds 5083-H111 aluminum alloy. MIG welds and FSP specimens were evaluated using microstructure examination, tensile, and hardness tests. The microstructure investigation of FSP specimens reveals a very fine grain size in the processed zone, and reduction of welds defects compared to MIG welds. FSP of weld surface without reinforcement improved the tensile strength when compared with MIG welds, when pinless tool is used. In addition, the processed zone record higher hardness values than the base metal as well as the MIG welds.

Abstract: This article reports the results of comparative analysis of the significance of categorical factors with two to five levels influencing safety on interstate highways. The study used the Highway Safety Information System (HSIS) accident data observed on interstate highways in the State of Ohio for the five years period ranging from 2010-2014. The analysis considered about thirteen potential variablesincluding roadway design elements, environmental conditions, drivers' demographic factors, time of the day, and day of the week. The results suggest that among the variables considered, only about half of the factors appeared to have significant differences in crash rates across their respective categories. The identified explanatory variables are mainly associated with highway design elements such as median type, number of lanes, access control and contour of the roadway; and the drivers' age and gender..

Abstract: This research integration of lean manufacturing and six-sigma was carried out in the Nigerian Breweries Enugu Plant where management strategies were not so developed. The main objective of this work was focused on the minimization of the line wastes such as time, over-processing, over-production or defects. The DMAIC (Define-Measure-Analyse-Improve-Control) was the methodology used for the identification of compatible lean techniques and strategies for the reduction of defects and rejects bottles in the company. Data were collected and analyzed using statistical methods. The result showed the production line A rejects 0.37% of the produced bottles against 0.23% of the production line B. This showed that production line A rejects one bottle in every 271 bottles against one bottle from 435 bottles in the production line B. The result also showed that minimum and maximum value for extraction...........

Abstract: Productivity is a measure of the effective use of resources.It is the relationship between result and the time it takes to achieve the results. Leather processing is a high labour intensity process of converting hides and skins to leather which is a source of employment. However, leather production in Kenya has not reached full potentialas a result of low productivity by individual tanneries. This paper evaluated productivity level Key Performance Indicators(KPIs'), sought knowledge by analysing the OEE, throughput analysis, cycle time analysis and labour productivity analysis. The study was done through observation,assesment of company records and documents and...........
