Evaluation of Efficiency and Performances of Building Materials used in Sudan Combined with Lead as the Gamma Ray Shieldings

In this study the linear attenuation coefficient µ and the half value layer HVL of some building materials like iron, concrete, cement and clay used in Sudan as a combined with the lead have been investigated, the results have been experimentally determined using Cs 137 and Co 60 source and compared with the theoretical values. The measurements were performed for radiation intensity without shielding and with specific thickness of selected samples using ion chamber placed at 2 meters from Cs 137 and Co 60. An obtained results showed that the linear attenuation coefficient µ has a linear relationship with the corresponding densities of the samples studied and inversely with photon energy, and the half value layer HVL was proportional directly with photon energy. As a results of this evaluation the lead combined with the selected materials as indicated above showed an improvement the efficiency of building materials as the gamma ray shielding.

Electronegativity A Force or Energy

Electronegativity as force or energy leads to new ansatz at critical point in binding or bonding state in between two similar atoms or dissimilar atoms. Electronegativity as a quantum mechanical entity energy or non quantum entity force is yet to be answered. The dual approach to electronegativity has been discussed in this paper. The aim of this paper is to prove that Electronegativity as Hellman Feynman Force is more accurate and absolute. Electronegativity has been computed using the Hartree Fock and Rothan Hrtree Fock energy equations and equivalent electrostatic force equation.

Determination of Drying Constants of Some Selected Roots and Tubers

In an attempt to easily determine the desired moisture content at any time t , of selected freshly harvested roots and tubers yellow cassava, carrot, cocoyam and yam of economic importance subjected to drying under unsteady temperature conditions such as sun drying, especially in the rural areas where there is no electricity or funds availability to acquire suitable drying equipment by local farmers the drying constants based on established model that is anchored on mass of the material

at any time t was carried out. In this study, three mass classifications, namely small, medium and large were prepared for each material and subjected to oven drying at a given temperature till bone dry mass. The experimental values obtained were computed and graphs plotted to obtain the slopes as drying constants of values 0.3114, 0.1092, 0.3736 and 0.3790 for bulk samples of yellow cassava, carrot, cocoyam and yam respectively.

A two Stage Fuzzy Logic Adaptive Traffic Signal Control for an Isolated Intersection Based on Real Data using SUMO Simulator

In this paper, a two stage fuzzy logic system has been proposed to control an isolated intersection adaptively. The aim of this work is to minimize the average waiting time for a different traffic flow rates in real time means. In the first stage, the system consists of two modules named next phase selection module and the green phase extension module. In the second stage the system consists of the decision named module. The study was performed using SUMO traffic simulator. A comparison is made between a fuzzy logic controller and a conventional fixed time controller. As a result, fuzzy logic controller has shown better performance.

Face Recognition Based Intelligent Door Control System

This paper presents the intelligent door control system based on face detection and recognition. This system can avoid the need to control by persons with the use of keys, security cards, password or pattern to open the door. The main objective is to develop a simple and fast recognition system for personal identification and face recognition to provide the security system. Face is a complex multidimensional structure and needs good computing techniques for recognition. The system is composed of two main parts face recognition and automatic door access control. It needs to detect the face before recognizing the face of the person. In face detection step, Viola Jones face detection algorithm is applied to detect the human face. Face recognition is implemented by using the Principal Component Analysis PCA and Neural Network. Image processing toolbox which is in MATLAB 2013a is used for the recognition process in this research. The PIC microcontroller is used to automatic door access control system by programming MikroC language. The door is opened automatically for the known person according to the result of verification in the MATLAB. On the other hand, the door remains closed for the unknown person.

Child Rescue System from Open Borewells

In present time, children fall in the Borewell due to the carelessness nature of the people in society. The currently available systems to save the child are less effective and costly too. Thus the society is in need of a new technique which is more efficient and effective. In most cases reported so far, a parallel hole is dug and then horizontal path is made to reach the child. It is not only a time taking process, but also risky in various ways. The borewell rescue system is capable of moving inside the same borewell where the child has been trapped and performs various actions to save the child. CCTV camera is used to continuously monitor the child's condition. This system has a high power LED which acts as a light source since light intensity inside the hole will be less. The advancement in the field of automation along with the mechanical design has a great impact on the society. This project includes series of process development from hand drawn sketches to computer generated design. The modern equipments are implemented for various parts of the system, since the system performs a life rescuing activity. The light weight servomotors are implemented for the system's operations. Borewell rescue System is a human controlled computerized system embedded with additional safety devices.

Harmonics Reduction and Power Factor Improvement of Switch Mode Power Supply by Using Zeta Converter

This article describes the topology of a DC DC converter operating in switching mode on off . During the completion of the switching cycle, the entire current flow may be resolved and the load may be left. Under these conditions, the initial conventional upconverter switches are heavily loaded and result in large power losses. Switches with boost converters provide low loss, high output voltage, high efficiency, small size, reduced electromagnetic interface EMI , and low voltage components for power supplies.
