The study aims to manufacture modeled building green bricks with different cheap solid additives having a high heating values [industrial and agricultural], petro-coke, animal dung, and saw-dust as an internal fuel. Model samples were manufac...
ABSTRACT A heat exchanger is a medium that transfers heat energy from a high temperature fluid to another low-temperature fluid without mixing the fluid together. Thermal exchange is one of the most important applications in many fields, such as food processing engineering, especially in the manufacture of materials that are highly sensitive to high temperatures, as well as difficult to heat or raise their temperature by direct methods and other materials. Heat exchangers are used in many en...
ABSTRACT . The surface charge density (σo) of colloidal alpha-alumina suspended in various 1:1 electrolytes was measured using acid-base titration. An auto titrator capable of dispensing accurately 25 ± 0.1 µL of titrant was used. The pH and temperature in the titration cell were monitored using single-junction electrodes and platinum resistance thermometers, respectively. A constant supply of nitrogen gas in the cell was used to maintain inert conditions. The whole set-up was interfaced w...
ABSTRACT According to the definition of Third Generation Partnership Program (3GPP), Machine Type Communication (MTC) is a new type of data communication between machines and devices without human interactions. Long Term Evolution (LTE) is a recent 3GPP cellular standard and is a promising technology to support future MTC data traffic. One of the main goals of LTE is to provide fast and seamless handover from one cell to another to meet strict performance requirements while simultaneously ke...
ABSTRACT A means of providing radio broadcasting services by using Frequency Modulation (FM) technique is called FM Broadcasting. Aeronautical Communication Service refers to radio communication service intended for the safety operations of aircrafts. Aeronautical communication service is categorized by International Telecommunication Union (ITU) as a primary service. This service needs to be offered under frequency interference free environment for ensuring aircrafts navigation safety. Howe...
Abstract Fusarium wilt considered as one of the most important diseases of tomato in Sudan. The present investigation was undertaken under laboratory conditions to study the effect of different neem oil concentrations, and synthetic fungicide,(AmistarTop 200ml/100L Water), on growth of the fungus Fusariumoxysporumf. sp. Lycopersicithe causal agent of wilt disease on tomato. Three concentrations of neem oil (1.5, 2.5 and 3.5 %) and fungicide as recommended dose were tested in addition to cont...
Abstract Ever since the invention of cars accident was introduced as a major cause of death and car manufactures has been developing new ways to prevent death by accident. Time is very important factor when it comes to saving a person’s life, any delay in detecting an accident or failing to locate its position life. The solution proposed by this thesis is to use a combination of collision detection unit and identify an accident and report it to the appropriate authorities and clear the roa...
ABSTRACT A Mobile Ad-Hoc Network (MANET) is a popular type of wireless network that is formed by a collection of mobile nodes. Each node in such network has the capability to communicate with its neighbors and nonneighbors through a wireless medium designed to accommodate the properties of a self-organized environment without protection against any inside or outside network attacks. In addition to, it does not have any central authority to ensure that any node in the network it is not malici...
Abstract The purpose of this project is to study the effects of turbocharger technology in a diesel engine. The Perkins diesel six cylinders 4 stroke Stationary CI Engine (case study) comes without a turbocharger. The Study is based on predict the effects of using this technology in the performance of engine, air pollution and global warming by calculations and simulation. After the calculations and simulation found that Recovering technology is decreasing the temperature of exhaust gas from...
The exponential growth of mobile data traffic affects not only the capacity requirements of the mobile networks, but even the expected quality of service. The introduction of LTE improved the situation to some extent. However, as a high percent of mobile data traffic is generating from indoors, LTE operating at higher frequencies cannot really meet the ever-increasing demand of data traffic and reasonable quality of service. This Thesis provides an analysis of the network throughput with LTE ...
ABSTRACT Being able to assess the hydrologic ability of Abu Habil catchment to satisfy its future water demands is crucial in order to plan for the future and make wise decisions. In this study a Scenario Analysis approach was used by utilizing NB-DSS model for water resource management, evaluation allocation and planning, in order to assess the impacts of possible future water demands on the water resources of Khour Abu Habil catchment. For each scenario, the main outputs of the model were ...
Abstract: Kaplan Hydraulic Turbines defined as prime movers that transform the kinetic energy for the flow rate of water and head to mechanical energy and electrical energy by electric generator shaft. And knowing the efficiency of a hydraulic turbine has important operational and financial benefits to those who operate in power plant stations. This research focused on the analysis of the effect of the head and the rate of discharge on the energy produced and compared with the other theoret...
Abstract A Long Term Evolution (LTE) technology is the most possible candidate for next generation mobile wireless communications. One impairment of LTE is an interference from neighboring cells, so called Inter-Cell Interference (ICI). In this thesis Fractional soft FFR technique has been introduced for better utilization of frequency spectrum. In addition, beamforming technique is considered to be the solution to improve the performance of wireless communication systems, this thesis propos...
Abstract With the growing population rate, the amount of waste being produced is also increasing at a very fast rate. These days in our environment waste management is one of the major problems, the best solution has been proposed to solve this problem is segregating this waste and recycle it. But segregating it manually is complex, dangerous and utilizes more human efforts, cost and time. The proposed system designed to separate five types of wastes into respective bins automatically by the...
