Productivity of a system is one of the key factors that affects overall competitiveness of an organisation. Productivity is the measure of the effective use of resources which is expressed as the ratio of output to inputs. Therefore productivity is the relationship between result and the time it takes to accomplish them and it is used to examine efficiency and effectiveness of any activity that is conducted in an economy,business or an individual hence it refers to the measure of the efficie...
ABSTRACT In this thesis, the objective is to determine the steady state operating condition of thirteen bus Ogui- Enugu Radial power distribution network. The steady-state was determined by finding out, for a given set of loading conditions, the flow of active and reactive powers throughout the network, the voltage magnitudes and phase angles at all buses of the network. This was achieved using Newton- Raphson power flow algorithm written in MATLAB environment. A critical analysis of the net...
ABSTRACT This project involves research on loss reduction in a distribution system. The Enugu distribution system is the case study. The type of losses, the causes of losses and methods of loss reduction in distribution system were presented. A method based on a heuristic technique for reactive loss reduction in distribution system is chosen for this work because it provides realistic sizes and locations for shunt capacitors on primary feeder at a low computational burden. The Gauss-siedel m...
Abstract Due to intense global competition and increasing demands from stakeholders, companies are striving to improve and optimize their productivity in order to stay competitive. The performance and competitiveness of manufacturing companies is dependent on the reliability and availability of their production facilities. Therefore, it is the objective of the maintenance department to maximize the machine availability. The use of effective maintenance policies is one of the methods that hav...
ABSTRACT A research was carried out at the Ngongongeri Farm Kenya to determine effects of tillage depth and speed on drawbar power and performance of disc and mouldboard ploughs so as to develop a mathematical model that would assist farmers, machinery managers and policy makers to properly match implements to tractors and the size of tractors to import based on soil types and conditions. The implements used were a standard 2-bottom mouldboard plough and a 3-bottom disc plough. Tillage depth...
The use of technology in communication has proliferated in the last decade, more so with the advancement of mobile technology which has made information dissemination and reception more instantaneous. With the advancement in mobile communication technology, platforms have come up and have been adopted by many who find them appealing. One of these platforms is WhatsApp, whose adoption rate has enormously grown from its inception in 2009, with the current number of users surpassing 1 billion in...
The purpose of this project was to build a motion detector. The main components used were the Arduino microcontroller and the PIR sensor. The project also used an LED and a Piezo buzzer to indicate when motion was detected. The group sought to demonstrate the workings of each component as well as how they work together to carry out the task. The group also drew up a circuit from which the components were connected. The main objective for the project was to practice the skills learnt over t...
ABSTRACT This research work undertakes the development of water pumping system (with emphasis on Irrigation) that is capable of automatically managing water budgets from a reservoir through a microcontroller subsystem. The water pumping for irrigation system can be used in gardens, farms, urban/rural water supply systems, and in fact, general water management systems for both domestic and industrial applications. The key objective of this research is to develop a user-friendly and efficient ...
ABSTRACT This thesis presents the performance characteristics of a Transfer Field (TF) machine. In this machine, the two component fields revolving in the airgap are of the same pole number and the speed of operation is inversely proportional to the sum of the two pole numbers, that is, half the synchronous speed 𝜔2 of a normal induction motor. There is thus, a close relationship between the self-cascaded induction machine and the TF machine. It is shown that if the reactance of the...
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...
