Abstract: One of the procedures for obtaining the better understanding of the system by splitting the large system into smaller parts, this procedure is termed as analysis. Manually creating softwareartifacts and building UML models from natural language is a complex job. We represent diagrammatically structure of data by ER diagram. This paper represents the use of heuristics picked up from the syntactic and semantic learning for the automatic formation of database plan, which leads us to the identification and methodology to generate Entity-Relationship(ER) through NLP.

Abstract: This paper presents the pre-processing scheme used for a vision system for a self-navigating mobile robot which relies on straight line detection using the Straight Line Hough transform. The straight line Hough transform is an Image Processing technique for detection of straight lines in an image by transforming points in the image to another image in a way that accumulates evidence that the points from the original image are constituents of a straight line type feature from the original image. The pre-processing presented includes image re-sizing, conversion to gray scale, edge detection using the Sobel edge-detection filters, and edge thinning with a newly developed method that is a slight modification of an existing method. The newly developed method has been found to yield thinned images more suitable for later stages of this work than other thinning methods. Output from the pre-processing scheme presented is used as input for the remainder of the vision-based self-navigation system.

Abstract: In this research two flat glass mirrors is used as concentrator of solar panel system. The mirrors increase's the concentration of sun light ray on the solar module. Anew model of solar panel system is designed by mean of software Zemax in order to find best possible inclination angle of the concentrator that improves the performance of the solar panel. So the efficiency is 59.5% for designed system with inclination angle 60° of the concentrator. Then a practical design for the solar panel system with concentrators is established. The outdoor measurements for the practical design indicated that the output power and efficiency is increasing by increasing the inclination angle of the concentrator and reaches its maximum value at 60o at different times of the date 5-2-2014. Also the results showed that the maximum value of efficiency is 0.85 at 11 o'clock at 60o. While the maximum value of the output power is 72.8w at 12 o'clock of the same day.
