Abstract : The important performance parameter such as material removal rate(MRR) and surface roughness(SR) are influenced by various machining parameters namely voltage, feed rate of electrode and electrolyte flow rate in electrochemical machining process(ECM). In machining, the process of modelling and optimization are challenging tasks to qualify the requirements in order to produce high quality of products. There are a lot of modelling techniques that have been discovered by researchers. In this paper, the optimize settings of performance parameters; surface roughness and MRR are done by the Taguchi technique and the experimental result of MRR and SR was predicted by the Multi-layer Feed forward Neural network (MFNN) and Least square support vector machine (LSSVM). For Taguchi analysis three process parameters and two responses, MRR and SR were considered by L18 orthogonal array design and ANOVA result were performed. EN19 material used as the work piece for the experiment. After evaluating MFNN and LSSVM models, the best network found to be Least square support vector machine with RBF kernel. The mean square errors (MSE) between actual and predicted response obtained in both LSSVM model and MNFF model for the training and for testing datasets were concluded that LSSVM as more powerful machine learning tool and predict the MRR and SR successfully compared to other models. The performance of LSSVM is depend different kernel function that can separate the data from hyper plane for better prediction however we use Linear and RBF kernel. RBF kernel gives better prediction of MRR and SR with minimum MSE.

Abstract : The purpose of this paper is to discuss the effect of implementation of total quality management (TQM) in manufacturing industry (Mohindra Fasteners Ltd.) . Very few service companies have been able to reap full benefits of TQM. One major reason for its inadequate success is that of trying to implement in service companies techniques that have been successful in manufacturing. In manufacturing, emphasis of TQM is on "zero defects". Control charts and sampling are the major tools of quality control. However, in services, emphasis is on "zero defections". Focus is on customer satisfaction and team approach. TQM can boost profits and improve customer satisfaction by reducing deffects.

Abstract: The objective of this research was to gain a better understanding of Mechanical properties of epoxy resin composites reinforced with carbon fiber. The effect of fiber orientation of laminates has been investigated & experimentation was performed to determine property data for material specifications, the laminates were obtained by hand layup process .The laminates were cut to obtain ASTM standards. This investigation deals with the testing of tensile and flexural strength on a universal testing machine. The graphs that are obtained from the tests are documented. This research indicates that the mechanical properties are mainly dependent on the fiber orientation of laminated polymer composites.

Abstract:Industrialized Building System (IBS) is the new method of constructing building in the construction industry as a solution to improve construction image and performance. However this concept is generally accepted and applied in developed countries and some developing countries as well, does not have appropriate position in the construction industry in Iran. Most of construction companies in Iran still consist on conventional method instead of using IBS. This paper is attempting to find out the benefits and problems of applying IBS in construction projects, to identify the easiness of IBS usage for construction companies, to explore level of usefulness of IBS for Iranian construction companies and finally to recommend some solutions to promote IBS concept in developing countries. To collect data for this study, a questionnaire survey was conducted among the construction companies in Iran. A total of 827 questionnaires were sent out through mail and 117 of them answered. The respondent rate was 14.1%. It was perceived that, there is an acceptable range of knowledge on IBS among the construction professionals, but the level of the IBS implementation in construction projects was extremely low. Because higher cost, lack of expertise and lack of supportive rules and regulations.
