The Classification Of Lateritic Soils In Ikole As A Road Construction Material

ABSTRACT The performance of a pavement depends on the quality of its base, sub-base layers and sub grade. As the foundation for the pavement's upper layers, the subgrade layer plays a key role in mitigating the detrimental effects of static and dynamic stresses generated by traffic. Therefore, building a stable base course is vital for constructing an effective and long lasting pavement system. This study proceeds from the basis that, construction of foundations of most engineering structure...

Evaluation Of The Relative Difference Between The Provisions Of Bs 8110 And Eurocodes For The Design Of Reinforced Concrete Structures In Nigeria

Abstract The conventional method of design of reinforced concrete structures commonly used in Nigeria is the BS 8110 method. This project shO\S a comparative stud~ of BS 8110 and Eurocode 2 for the design or reinforced concrete elements of a building Vith the aim of determining "hich of the two codes provides the most economic design is carried out using manual calculations. A library complex of three storey building was selected and designed taking into account dead and live loads and assumi...

Development Of A Spur Gear From Carburised Cast Iron For Application In Bottling Machine

ABSTRACT Spur gears are components used in power transmission in bottling machines. Bottling machine breakdowns are often the result of spur gear failure, and the cause of gear failure can stem from many issues, of which the most common is failure due to wear. This study, therefore, developed a spur gear with adequate mechanical properties that can function in such an environment. Pareto and metallurgical techniques were used to characterise the failure and its effects on the production proc...

Comparison Between Two Grades Of Cements For The Stabilization Of Ikole-Ekiti Soils

ABSTRACT The performance of a pavement depends on the quality of its sub-base and subgrade layers. As the foundation for the pavement's upper layers, the subgrade layer plays a key role in mitigating the detrimental effects of static and dynamic stresses generated by traffic. Therefore, building a stable subgrade is vital for constructing an effective and long lasting pavement system. This project work, review the investigation carried out on the strength characteristic of laterite in its na...

Mechanical And Microstructural Characterization Of Aluminium Metal Matrix Composite Reinforced With Particulate Periwinkle Shells

ABSTRACT This study is about the production and characterization of aluminium alloy-Particulate periwinkle shell composite. Composites were produced at 1 %, 5%, 10% and 15% weight fraction of Particulaf'e periwinkle shell (PPS) fillers and the aluminium alloy was cast neat at 0%PPS which served as the control. The microstructures of the composites were studied with Optical Microscopy. Mechanical properties of the composites such as tensile properties (tensile strength, Young's modulus, ...

Development Of A Pedal Powered Washing Machine

ABSTRACT The PEDAL POWERED WASHING MACHINE is a project, which is undertaken to solve the problem of electric supply to people in rural areas. To run a washing machine, the source of power is electricity. In Nigeria most of the villages are suffering from shortage of electricity. So to overcome above problem we select the washing machine, which is operated manually. It requires no electric power supply or diesel supply. This project is low weight & portable can be easily transported. We�...

Development Of A Low Cost Biomass Briquetting Machine For Rural Communities

ABSTRACT The decrease in availability of fuel wood and rise in prices of fo~sil foels in Nigeria calls for considering alternative sources of energy for domestic and industrial use. This project was carried out in order to design and develop a low cost briquetting machine for rural communities. It involves the modificaion of hand use in producing briquettes by employing the use of hydraulic jack, moulds, pistons etc. This method is faster and easier. The agricultural residue used was 80% saw...

Development Of Autonomous Lawn Mower From Locally Sourced Materials

ABSTRACT A lawnmower is a machine that uses a revolving blade or blades to cut a lawn grass. Many designs have been made, each suited to a particular purpose. Manual grass cutter has environmental issues regarding pollutions and also require the need of man power to operate and has a great maintenance to its engine. This robot is design to be environment friendly and operated by a rechargeable battery and can be describe as an intelligent robot because the microcontroller receives information...

Design And Implementation Of A Mobile Surveillance Robot With Night Vision Camera

ABSTRACT Mobile surveillance robot is a robot which is used for the purpose of surveillance. monitoring, analysis of data and gathering of information with or" ithout the approved know ledge or the holder of the in formation and the timely d issem i nation nf in format ion to those who need to know so that action can be taken. The designed mobile survei I lance robot has a night vision camera with the ability to monitor its surrouncling. environment and collect data from it. The need to surve...

Design And Construction Of A Fan And Light Automation System

ABSTRACT Electricity is one of the foremost necessary resources during this century which needs to be conserved otherwise the next generations might be deprived of the opportunity. However there is tendency we leave our various rooms and offices and forget to switch off the lights and fan, so electricity is wasted. Additionally in most cases, switches of lights and fan are situated in places where we might need to search for them in the dark and just in case of guests, it becomes tougher. Th...

Determination Of The Mechanical And Microstructural Properties Of An Armour Steel For High Impact Performance

ABSTRACT The research evaluates the chemical, mechanical and microstructural characterization of an armour steel sourced from a scraped armoured vehicle in order to develop local content in the armouring technology. Chemical analysis, optical microscopy and mechanical tests were employed to examine the microstructural and mechanical properties of a low carbon armour steel. Chemical analysis showed the elemental constituents and the exact weight per percentage of each element present in the t...

Heat And Mass Transfer Analysis Of Potato Drying In A Kerosene Heated Oven

ABSTRACT Majority of small scale farmers and homes are still using open-sun and/or non-convective methods for drying due to either high cost of gas/electric dryer or lack of electricity in their locations. These methods are time consuming and exposed the products to rain and contamination. A maintenancefriendly and properly enclosed dryer is therefore desired. The batch kerosene heated dryer was studied and adapted to suit the need of these people. In this work, the heat and mass transfer an...

Derivation Of The Bandwidth Resource Allocation In An Atm-Based Network

 ABSTRACT Asynchronous Transfer Mode (ATM) technology is the transfer mode for implementing a Broadband-Integrated Services Digital Network (B-ISDN). ATM defines multiplexing and switching techniques for broadband signals. Synchronous Optical Network (SONET) is employed in the B-ISDN backbone. The main objective of an ATM is to guarantee Quality of Service (QoS) in transfer of cell streams across networks. This technology recommended as the transport vehicle for the B-ISDN offers a great fl...

Motivational Factors In Human Resource Management (Hrm) In Construction Projects –A Case Study Of South-South Nigeria

Abstract The primary objective of this study was to investigate the rank importance or most significant motivating factors on construction employees in South-South Nigeria.
