ABSTRACT In Multiple Input Multiple Output (MIMO) Radar every antenna element transmits different waveforms, these waveform diversity enhanced MIMO Radar system dramatically. Coherent MIMO radar array elements are close enough so that every element sees the same target radar cross section (RCS). The target response is mainly interrupted by the unwanted signals (Noise, Clutter, and Jamming) associated with receiving signal that degrades Probability of detection as well as performance of MIMO r...
Abstract: Several new techniques are developed within the previous couple of years that convalesce results on special filters by take away the noise additional with success whereas protective the sides within the information .Image de-noising plays an important role in satellite communication and signal processing applications. In this research , I suggest an median filter ,NLmeansfilter ,Total Variation (TV) ,Hybrid Median Filtering (hmedian), Speckle Reducing Anisotropic Diffusion Filterin...
Abstract Most variable speed wind turbines have pitch angle control mechanisms and one of their objectives is to extract maximum power from available wind speed, by adjusting pitch angles of wind turbine. In this research, the use of pitch angle control using PI controller is presented for wind turbines equipped for a three turbines with self-exited induction generators (SEIGs). The converters are used to extract the maximum available power from the wind. All machines are connected to a dc b...
Abstract The manufacture of plastic bags (HDPE, LDPE, LLDPE) is one of the leading industries in the world and has a strong consumer demand for packaging and packaging. The research examined the design of the film machine by analyzing the model of the bag blowing machine. Since the emergence of the rough and the formation of the balloon focus on the cooling area when the formation of the balloon and to make the roll to be ready for the stage of cutting (finished product). And compared this a...
Abstract The Vierendeel girder definition is open-frame N-truss without diagonal members, with rigid joints between the top and bottom chords and the verticals are known also as open-frame girder, this research is conducted to study the structural performance of different Vierendeel frame. Three models of the Vierendeel (1, 2& 3) were studied for their structural performance using approximate method and structural analysis programs such as SAP2000 and ROBOT STRUCTURAL for different loadings ...
ABSTRACT Cavitation is the appearance of vapor cavities inside an initially homogeneous liquid medium, occurs in very different situations. According to the flow configuration and the physical properties of the liquid, cavitation is the most commonly required one in all the researches on the pumps and flow systems but they are too hard to manipulate with the primary methods. In this research was study the effects of rotational speed (rpm); flow rate (Q); fluid temperature (T) and pressure (P...
Abstract This research presents the results of numerical study of heat transfer and pressure drop behavior in a compact heat exchanger (CHE) designed with drop-shaped pin fins. The heat exchanger used for thisresearch consists of a rectangular duct fitted with different drop-shaped pin fins dimensions with the same heat transfer wetted surface area.A three dimensional finite volume based numerical model using ANSYS FLUENT 14.5 has been conducted to select the optimum pin fin dimension conside...
Abstract Abrasive Water Jet Machining – (AWJM) become one of popular and growing processes among Advanced Machining Processes. It has high material flexibility and advantages of geometric, and ability to cut materials that are hard to machine using conventional technologies, it reduces the time necessary for secondary operations like programming, tool changing, or clamping. this allows a significant optimization of the overall manufacturing process chain. All these Advantages lead to (AWJM)...
Abstract The highway system of a developed country contains thousands center line kilometers of streets. Such systems consist of asphalt, concrete or composite streets ranging in condition, in recent years, several road network monitoring and maintenance programs have been established in order to monitor the on-going performance of the road network, to predict future road conditions and assess long term needs, to support investment planning and decision making, and to identify rehabilitation...
Abstract Modern power systems networks consist of a number of utilities interconnected together. Power is exchanged between utilities over tie-lines by which they are connected. Automatic generation control (AGC) plays a very important role in power system. Its main role is to maintain the system frequency and tie-line flow at their scheduled values during normal period and also when the system is subjected to small step load perturbations. The most commonly used controller is the PID contro...
ABSTRACT The main purpose of this project is to design a motorized, voice controlled wheelchair by using speech recognition module The objective of this project is to facilitate the movement of people who are disabled or handicapped and elderly people who are not able to move well. The result of this design will allow certain people to live a life with less dependence on others. The design supports voice activation system for physically disabled persons. Arduino microcontroller and speaker d...
Abstract: Through centuries, the man try to optimize jobs, and reduce the costs. In transportations system, the compact one is more desirable. In this research the sand pneumatic conveying system, used in Garri-4 power plant CFB (Circulating Fluidized Bed) boiler, a problem of high rate erosion studied. And the research aiming to find optimum and reliable solution for it. Experimental test done by using sand-blasting machine to simulate and to test the proposed solution, which is the change ...
Abstract In this thesis a method based on Particle Swarm Optimization (PSO) algorithm, which represents one type of modern optimization techniques is presented to determine the optimal parameters of Power System Stabilizers (PSSs) found in Sudanese National Grid, instead of classical control approaches. In addition TCSC is implemented in the National grid to increases the performance of the system by decreasing reactance of the transmission lines and hence increases the power flow in the lin...
Abstract: This study was dealing with assessment of groundwater quality and its fitness for agriculturaland domestic uses for Umbada district in western Omdurman, Sudan. The objectives of the study were to determine the groundwater quality through chemical and microbiological analyses for the samples taken from the studied boreholes in the area under investigation. Water samples for five groundwaterwells were collected in poly ethylene bottles and analyzed physically, chemically and bacterio...
