Abstract: The main purpose of this study is to develop a comprehensive success model for real estate projects considering both external and internal factors. In this respect, a wide range of success criteria are identified based on an extensive literature survey, and these criteria are classified into their respective sub criteria. In this context, a questionnaire was developed to facilitate systematic data collection in this study. In this survey, experts’ opinion from professionals and academicians of civil engineering field is taken through questionnaire. Top level managers, Senior civil engineer and Professors were involved for data gathering and finalizing the project Success Criteria and their respective sub Criteria. Further attempt has been made to formulate a fuzzy set numbers and employing Fuzzy Multiple Criteria Decision Making technique with a view to determine success potential of real estate project. The two main objectives achieved from this study, first, to provide a success potential index for completed projects in order to compare them with each other and to establish for improvement in future projects. Real estate companies may benefit from the findings of the proposed model in assessing the performance of their projects and may take the necessary actions to achieve better success in their projects to make a reputation in market.

Abstract: The solution of one or more control optimization problems regarding automatic generation control (AGC) through the efficient techniques are required in interconnected areas of power system. Heuristic optimization methods have replaced the analytical methods to tune the parameters of controllers used in power system since the analytical methods suffer from slow convergence and the curse of dimensionality. In the same direction, the Particle Swarm Optimization (PSO) technique among the swarm intelligence family has been applied in order to improve the performance of the two area interconnected thermal power plants. Proportional Integral Derivative (PID) controllers and Proportional Integral (PI) controllers have been employed in the system under study and the PSO optimization technique has been used to optimize the parameters of PI and PID controllers by considering the Integral Time Multiplied by Absolute Error (ITAE) as the objective function. Both the approaches PSO/PI and PSO/PID have been compared for the same system under investigation to show the superiority of the PSO/PID approach. The results have been simulated with the MATLAB /SIMULINK environment and it has been shown that PSO optimized PID controllers for the LFC provides the better dynamic responses than PSO optimized PI controllers for same system.

Abstract: The performance, reliability and load transferring capabilities of bearing elements are very important in industrial applications. The newer design of high speed machines demands better bearing system. The reliability is of primary importance in case of bearing elements used in aerospace industries. Exhaustive studies have been carried out by different researchers under two extreme conditions. One is using a fluid as lubricants which do not bear shear loads. The other extreme were using hard coatings which bears enormous amount of shear loads. In the present investigation an attempt has been made to understand the kinematics of deformation of balls and coatings which are not as hard as conventional coatings without lubricants. Different ball materials like case hardened carbon steel, high carbon high chromium steel and stainless steel, case hardened carbon steel and high carbon high chromium steel balls were coated with tin and case hardened carbon steel and stainless steel balls were coated with zinc by electroplating coating technique. The thickness of the coating was maintained at 25 µm. Four ball test rig was used to simulate the field condition. The experiments were conducted without lubricants. The normal loads were 100N, 300N and 500N respectively for case hardened carbon steel and high carbon high chromium steel, run for a period of 5 minutes. The normal loads were 50N, 75N and 100N respectively for stainless steel and run for a period of 5 minutes. The frictional load and normal load were monitored and co-efficient of friction was estimated. The wear scar was studied under scanning electron microscope. The co-efficient of friction was found to be dependent on normal load and type of coating material. The coefficient of friction was found to be minimum of value 0.27 for a maximum normal load of 500N for tin coatings and 0.41 for a maximum load of 500N for zinc coatings. The morphology of wear scar studied in scanning electron microscope explains the dependency of co-efficient of friction on normal load and different coating materials.

Abstract: Groundwater level fluctuation in aquifer system plays the main role in quantitative water management especially in semi arid and arid areas. In practice, due to aspects of time and cost, data monitoring of water levels is conducted at a limited number of sites, and interpolation technique such as kriging is widely used for estimation of this variable in unsampled sites. The main objective of this study is to get a better understanding of the temporal and spatial variability of the groundwater level fluctuation in regular monitoring wells constructed by the ministry of water resources in zahrez basin, Algeria. In this study, seasonal groundwater level data for 57 wells were collected from 1994 to 2011 and analyzed using the geostatistical approach. The Kolomogorov–Semirnov test revealed that all data followed normal or log-normal distribution. Experimental variograms are fitted by variogram models and computed to be used in the kriging estimations. The results of variographic analysis indicate that experimental variograms are best fitted by the gaussian model and the exponential model. Nugget-sill ratio (<25%) revealed that the groundwater levels have strong spatial dependence in the area. Kriging interpolation techniques have indicated the groundwater flow directions remained almost constant over the years.

Abstract: Different fall-recognition arrangements have been already proposed to make a dependable observation framework for elderly individuals with high necessities on exactness, affectability and specificity. In this paper, an improved fall recognition framework is proposed for elderly individual observing that depends on keen sensors worn on the body and working through purchaser home systems. With treble limits, inadvertent falls can be distinguished in the home social insurance environment. By using data assembled from an accelerometer, cardio tachometer and shrewd sensors, the effects of falls can be logged and recognized from ordinary every day exercises. The proposed framework has been conveyed in a model framework as itemized in this paper
