ABSTRACT Construction industry has complexity in it nature because it contains large number of parties such as clients, consultants and contractors. The factors that influence construction management practice differ from country to country, due to prevailing conditions. The objective of this project is to identify factors that influence construction management practice in Nigeria construction industry and elicit perceptions/ranking of the severity using relative importance index of the vari...
ABSTRACT Contamination of existing and potential agricultural lands is a major problem associated with the processing and distribution of crude and refined petroleum products in many oil producing countries like Nigeria. Hydrocarbon contaminants in soil are potentially phytotoxic to plants and interfere with plant establishment and growth as well as other land uses. The problems of pollution have led to the exploration of many remedial approaches to effect the clean-up of the polluted soils....
ABSTRACT Glass mat reinforcement, which can be easily shattered, is widely used across the world in military, automobile, civil, railway and electronic engineering among others. This research investigated the fracture mechanics of reinforced polyester composites on exposure to sudden impact force, using experimental and analytical methods based on impact and Linear Elastic Fracture Mechanics (LEFM) test procedures, to study the stress distribution around crack tip and zone. Plies of randomly...
Just an overview.
Abstract Construction and use of electric cars have increased dramatically in recent years. It's totally silent, productive, wasteful to a minimum, and needs zero care. Although electric vehicles might help cut down on carbon dioxide emissions, the charging stations required to keep their batteries at an adequate level would put a significant strain on the country's electrical grid. Renewable energy sources, such as solar power, have the potential to lessen the burden on the power system. Ass...
ABSTRACT The quality of satellite communication link can be seriously affected by variable climatic phenomena such as rain, gases, and scintillation. As the frequency of operation increases 8 beyond 10GHz, the effect of rain becomes very severe with the growing need for high bandwidth frequencies such as frequencies in the Ku-band and Ka- band hence the need for better fade mitigation becomes necessary. In order to identify the appropriate rain fade mitigation technique, there is need to qu...
Abstract The utilization of solar energy is most concerned source in energy sector nowadays. The building integrated photovoltaic solar panels are increasingly constructed in dense urban areas because they brought many advantages to the society along with energy saving features. However, at the same time, they raise tensions in capital investments and overall returns. In this project, the BIPV systemis integrated on a multi-stair building consists of 6 floors, this building is located in...
ABSTRACT Automatic plant irrigation system rise as a good choice and alternative to traditional irrigation methods since it is saving time and effort that are consumed by traditional methods where people are compelled to stop doing their important activities. The aim of this thesis is to develop a microcontroller-based automatic irrigation system. This system will run automatically by referring to the level of soil moisture. The humidity sensor type connected to the microcontroller is soil m...
Abstract The focus of this research work is to derive a model that will be used to obtain the adsorption efficiency of an adsorbent for the removal of lead and copper from waste water. To date, the prevalence of adsorption separation remains an aesthetic attention and consideration abroad the nations owning to its low cost, simplicity of design, ease of operation, insensitivity to toxic substances and complete removal of pollutants even from solutions. The data points for this work were col...
ABSTRACT SWAT was applied a large watershed (3,765km2 ) in south-eastern Nigeria, to predict streamflow and sediment discharge from the Ebonyi River Watershed using globally available data downloaded from the internet. Digital elevation, land-use and soil maps of the study area from global databases and historical weather data measured locally were used. SWAT model was setup to use the MapWindow GIS interface. The model predicted an average daily streamflow and sediment discharge of 24.32m3 ...
ABSTRACT In the study of the influence of saliency ratio (L /L ) on the performance of a synchronous reluctance generator (SRG), this project investigates two typical generator rotor designs: Generator with cage and without cage otherwise known as cage and cageless rotor respectively. A special attention had been paid to the possible rotor geometries of synchronous reluctance machine, SRM. This ratio can directly influence our insight into the machine’s potential abilities. From the studi...
Predictive Analysis using Decision Tree, Random Forest and K-Nearest Algorithm
This project involves the use of an inductive sensor to control a robotic arm system. The signals generated in the induction coil will help in controlling the manipulator to perform certain gripping and grabbing actions. Also, the report describes the method used to acquire and process these induced signals before they are sent (induced signals) to the manipulator through the help of two programmed microcontrollers.
The main content of this project is to mathematically use the method of bilinear transformation to design a digital bandpass IIR filter, which will cut off frequencies below 20Hz and above 500Hz, since in electromyography the dominant frequencies for myopic signals lie between the frequency range of 20Hz and 500Hz.
ABSTRACT It would seem that hearing is a secondrate sense when compared to vision in our visually oriented modern society. People with hearing loss delay a decision to get hearing help because they are unaware of the fact that receiving early treatment for hearing loss has the potential to literally transform their lives. Research by the National Council on the Aging on more than 2,000 people with hearing loss demonstrated t...
