ABSTRACT Land use/cover change alters the hydrologic response of river catchments. The response depends on the soil characteristics such as; infiltration capacity, porosity, organic matter content and bulk density. Understanding the effect of the land use change on soil hydrologic response in Upper Njoro River catchment is crucial for formulation and adoption of proper soil and water conservation techniques for increased agricultural production. Additionally, the characteristics of extreme ev...
The US Environmental Protection Agency (EPA) issued the first ever federal rule to permanently cap and reduce mercury emissions from coal-fired power plants on March 15, 2005. The rule referred to as The Clean Air Mercury Rule (CAMR) when fully implemented, will reduce utility emissions of mercury from 48 tons a year to 15 tons by 2018, a reduction of nearly 70%. These mandatory declining caps coupled with significant penalties for noncompliance, will ensure that mercury reduction requir...
Some industrial equipment such as electric tranformers and capacitors are located in vaults and substations on flat concrete surfaces. Due to accidents, normal routine maintenance, or replacements, this equipment may spill oil that may contain PCBs on these surfaces. These spills must be cleaned up in accordance with United States Environmental Protection Agency's (USEPA) guidelines. Current cleanup operations are abiotic in nature, encompassing both physical and chemical methods. These metho...
In this research was to highlight the most important sources possessed by any organization to achieve its desired image and increase their rate of production and increase their profits and expand their activities, making the construction industry in Sudan industry with many benefits such as opening business opportunities for human cadres in various specializations and take advantage of them and their energy and experience to the labor market in Sudan and work the establishment of proj...
Light fidelity (Li-Fi) is new technology using lights (LEDs) as transceiver to send and receive data. However, when Light fidelity access points (attocells) placing near to each other in the network, they interfere each other with phenomena called co-channel interference which decreasing quality of the signal. In this thesis, fractional frequency reuse introduced as solution to solve this problem. MATLAB simulator showing the impact of fractional frequency reuse to solve problem.
Radio Frequency based wireless remote control system can be used to control the output load from remote place. In this thesis a circuit of RF module ( Tx/Rx) for wireless remote control has been used for automatic collecting data from energy meter which called Automatic meter reading (AMR) instead of using traditional meter reading system for billing. In thesis AMR has been implemented to send and receive data between energy meter and electrical distribution company system. Simulation mo...
ABSTRACT Due to global competition, many organizations are coming up with ways of sharpening their competitive edge. This has been achieved through cost leadership, differentiation of goods and services and lastly, through quick response to the needs of the customers. To respond to these market requirements, manufacturers are using high-tech equipment. They are also adopting new material control methods such as Just-In-Time philosophy. Set-up costs are also being minimized to a minimum. All ...
Biodiesel is a clean-burning alternative fuel produced from renewable resources. However, it is susceptible to oxidative degradation due to autoxidation in the presence of oxygen, which hinders its widespread use. Antioxidant addition is a prospective solution to this problem. It is expected that antioxidants may affect the clean-burning characteristic of biodiesel. The aim of current study is to investigate the feasibility of biodiesel-diesel blended fuel of (30%, 35% and 40% biodiesel)...
ABSTRACT The Hydrogen sulfide gas released from the geothermal operations has a potential impact on the health of the workers and the community living within the vicinity and also the geothermal equipment. Similarly, this gas is a toxic pollutant when released into the atmosphere. Additionally, this gas is corrosive to metal-based materials including brass and iron when dissolved in water. In this regard, there is need to manage the concentrations of hydrogen sulfide in the atmosphere at acc...
Because of the significant importance of the gas-turbine engines as it is the core of the aircraft, the engine health status should be tested periodically. Testing methodologies are needed to conduct the engine tests required as a part of airworthiness certification. In this project a data acquisition system was developed as a gas turbine engine testing system. This system was developed to monitor the engine parameters to determine its condition and to control the engine starting compo...
ABSTRACT In real situation the physical earth is in three Dimension (3D), a two dimension (2D) and one dimension (1D) earth models may not therefore explicitly explain or characterize the 3-D Earth in all situations. This is a simple and apparent reason why one needs a higher dimensional interpretation of Magnetotelluric (MT) resistivity data in modelling geothermal reservoirs. 2D MT interpretation is frequently applied in geothermal assessment and in many cases has effectively provided accu...
Generally the anti-theft security system becomes very important these days according to the high rate recording of the theft crimes cases around the world. In this project the vehicles security system type will be the focus of the study. The main objective of this vehicle’s anti-Theft Security System project is to design a smart security system to provide the highest level of protection to the owners of the vehicles or the authorized persons for unauthorized usage objects. In the resu...
Abstract The basic goal of manufacturing industries is tomaximize profitability in order be competitive and stay in the market. This is mainly achievedby producing products at low cost to maximize profits. However,low productivity has been the major problem facing most manufacturing companies just like DMKL. Two major sections that are affected by low productivity in DMKL processing plant are Labeling and Parking section. Productivity in these sections stand at an average of 50% the rated ca...
ABSTRACT This research work is aimed at using the energy and exergy analysis with thermodynamic data to suggest improvements in the performance of steam and gas turbine power plants. In this regard, specific data from Egbin steam power plant and Geregu I gas turbine power plant were used for the analysis. In the analysis, scientific tools such as Engineering Equation Solver (EES) programme with built-in functions for most thermodynamic and transport properties was used to calculate the entha...
ABSTRACT This research work on “Modelling and Simulation of Leakage-Induced Pressure drops along oil and gas pipelines tends to develop flow equations that can detect and localize leakages in oil and gas pipelines by modifying the Darcy-weisbach equation for liquid/oil flow, and the Panhandle B equation for natural gas flow in pipelines. These modified equations were simulated using matlab to show how flow rate values for the oil and gas pipelines vary when; the pipeline is working at full...
