Abstract Deltaic lateritic soils of the Niger delta region of Nigeria differ markedly fiom the other lateritic soils because of some mode of formation related peculiarities. As the most widely used soil materials for road earthworks in the entire region, their continual exploitation based on properties of the more matured and widely studied lateritic soils of the hinterland has met with mixed degrees of failure and success. In this study, samples of this soil material fiom different locations...
ABSTRACT Clay soil posses a great threat causes problem on civil engineering structures due to its tendency to swell when it is in contact with water and shrinks when they dry out. Stabilization using chemical admixtures is the oldest and popular method of soil improvement. In this study, an investigation was conducted to explore the possibility of using processed termite mound as a stabilizing admixture to improve clay soils. This investigation involves the determination of the swelling pote...
ABSTRACT Security is one thing human should not joke with, especially in today’s world where crime is at a higher rate. One of the ways of providing security is the introduction of security doors in houses, companies, offices and warehouses. Security doors may prevent or control entry or exit, or they may be merely decorative. Larger doors can be used for a whole building, such as a castle or fortified town, or the actual doors that block entry through the gatehouse. Today many doors are ...
ABSTRACT A digitally controlled light dimmer circuit is based on the principle of power control using thyristor. The switch enables light from an electric bulb to be raised from full brilliance down or up to a high range of luminance. Owning to its construction, adequate conservation of energy is achieved. The circuit is made in various patterns depending on the manufacturer. Some have a rotary knob; some have milled edged control while others have a depressing switch or side...
ABSTRACT Relevant literature for the modeling and analysis of failure of GRP composites were reviewed. Samples of GRP composites were prepared by hand-lay up. Composites samples were subjected to compressive tests using a tensometer. Mechanical characteristics, such as modulus of elasticity; compressive strength, proportionality limit, elastic limit and critical strain of composites were evaluated from compression tests results. It was found that the compressive strength of all the samples is...
ABSTRACT An experimental evaluation of the performance of a charcoal stove designed to reduce human labour and health hazards associated with frying in open fire was carried out. The channel- type metallic stove was lagged with 2.54 mm thick glass wool. The charcoal grate is 160 mm from the floor and has 44 holes of 12 mm diameter each to serve as air holes and provide passage for ashes, drilled in it. The charcoal bed is 230 mm from the bottom of the pot and the channel gap is 8mm. A 300 mm ...
ABSTRACT Data warehousing and business intelligence are key enablers in the drive to harness management information and improve decision-making. They underpin the recent wave of interest in data mining and customer relationship management and create opportunities for performance improvements based on quantitative analysis at every level in an organization. Data warehousing is a relatively new field in information technology, and current research centers primarily on data warehousing in busi...
ABSTRACT This research work designs a wireless power transfer system (WPT) for non smart phones as an alternative to existing wired power supply systems for these devices. Initially, the general concept of known WPT systems and methods are introduced and reviewed. It was noted that most existing WPT models do not consider external interferences in their design even though, it is well known that high frequency circuits may interfere with a WPT system. Additionally till date, existing WPT syste...
ABSTRACT The construction industry consumes about forty percent of the world’s energy. The high increasing rate of construction activities has led to exploitation of most of the natural resources. These activities have led to massive deforestation and clearing of green cover for settlement and infrastructure development in Kampala. The repercussions of these activities are catastrophic such as poor air quality, urban heat island effect, toxic gas emission, increased cooling costs, which lat...
ABSTRACT In recent years the entire world is a warring about energy resources limitation, specifically Sudan country confronts critical crises in fossil fuel resources and yet more of electricity energy producing from fired thermal power plants. One from these plants Garri”2” combined cycle producing about 180MW. Exergy analysis in the light second law of thermodynamics is powerful tools to investigate from optimization of engineering devices. Exergy analysis has been carried out analytic...
ABSTRACT Robotic is an electromechanical system, help improve production accuracy, and reduces time and increase production. In this project a study of 3D robotic ARM design, simulation concepts and theories for the painting of cars that deals with the design, construction, operation, and application of robots is conducted. The simulation covers different parameters to evaluate the design. Moreover simulation environment help to test these parameters cost effectiveness of building robots and ...
Abstract In the agricultural projects that use the center pivot irrigation system, which depends on the groundwater wells as a source of water using turbine pumps, which are actuated by internal combustion engines, the suspension of the center pivot irrigation device on the movement when a malfunction occurs with its continuous flow of water is a big problem and waste water, fuel and time, It also damages some crops that are heavily affected by water,this research studies the design of an aut...
Abstract Abstract -This study aimed to use and attempted to apply total quality management TQM in the Sudanese garment manufacturing factories to improve productivity and profitability and product quality and solving the factory's problems to meet customer satisfaction and decrease the garment imported and determined the potential of competition of local factories in the local and global market. The study designed and employed two methods, one for local garments factories in Sudan and the sec...
