Correlation and regression in this paper were employed as analytical tools to study the degree of relationship as well as the nature and strength of the relationship between green concrete properties and percentage replacement of cement with civil engineering materials. Pearson product-moment method and Spearman’s correlation coefficient were extensively used to show how correlation analysis can be practically applied in green concrete research. Least square regression line method for b...

Abstract The aim of this work is to characterize properties and microstructure of stainless steel used as a coating on welding of carbon steel sheets. Two carbon steel plates were set as the metal base and the stainless steel coating was applied on the weld bead. The applied process used was the submerged arc welding (SAW) and tests were carried out for the tensile strength and Vickers hardness, in addition to observation of the microstructure by optical microscopy. The results indicated that...

ABSTRACT This project shows the construction of a microcontroller based security door using Smart card. It is aimed towards programming the microcontroller to control the Hardware in sliding door. The system consists of a microcontroller 89S52 which Sends a signal to the multiplexers on insertion of the smart card in the card slot. The multiplexers consist of ICS which prompts for a display of the identity of the Card user in the liquid crystal display (LCD). The LCD displays the status of th...
Abstract My project is to improve JIT store management system from manual to automated system. Which is used to avoid problem faced by store keeper when store material manually. Store is the place where many varieties of materials are kept for the purpose of work. So at a time of storage is hard to write in document all material listing by their name, id, model, price and quantity; and is also boring to search specific material from whole material for human being but is easy for computer ...
Abstract: Technology in our contemporary world has a whole lot of applications and has completely revolutionized the way we do things. Almost every quarter of a year something new that helps humans carry out activities in a simpler and efficient way is developed. With the level of advancement in the area of internet and computing, one can now successfully stay at home and learn or learn while on transit. This paper contains important information on how online learning otherwise known as E-lea...
ABSTRACT Automatic water level controller circuit automatically switches ON and OFF a domestic water pump set depending on the tank water level. This motor driver circuit can be used at home, industry, school or even in agriculture. The approximated cost of the project is very less. The main advantage of this water level controller circuit is that it automatically controls the water pump without any user interaction. The main controller component is a NE 555 IC. We have manipulated the flip f...
ABSTRACT This work investigated the variation of top loss heat transfer coefficient with the emittance of the absorber plate, the collector tilt angle and air gap spacing between the absorber plate and the cover plate. The effects of the emittance of the absorber plate, the collector tilt angle and air gap spacing between the plate and the cover on the collector performance were also considered. Data collected from the thermosyphon solar water heater constructed by the National Centre for En...
ABSTRACT Sugarcane as an agricultural product is a readily available source of food for its sugar content. However, Sugarcane Bagasse Ash (SCBA) is the bi- product formed at sugar industries from the burning of sugarcane after the sugar content has been extracted. Sugarcane Bagasse Ash (SCBA) is a fibrous waste product containing mainly aluminum and silica, calcium ions to produce calcium aluminate hydrate (CAH) and calcium silicate hydrate (CSH) shown in the pozzolanic reaction below. Ca2+ +...
ABSTRACT This project involves the design and implementation of an intelligent obstacle-avoiding robot car. The objective of this project is to implement a robot car, which while moving should have the ability to detect obstacles in its path and change direction where obstacles are present without any form of external influence. The new direction to be taken to avoid collision is the direction that has the most distance between the obstacle and the sensor and this is determined by the robot b...
ABSTRACT When comparing with other manufacturing technologies, the extrusion technology always stands out as it is known to be highly efficient in terms of producing products of superior quality with the least possible amount of wastage. With the ever-increasing cost of materials, energy and the competition in the market, it becomes almost necessary to device a model with the minimum number of trials and shortest lead time. A multi-hole extrusion process was hence devised to serve the above n...
This research investigates the improvement of the mechanical and durability properties of concrete using Date Palm Seed Ash (DPSA) as partial replacement of cement. The DPSA used was obtained by controlled burning of date palm seed in a kiln at a maximum temperature of 630oc for eight hours and after cooling, it was sieved through 75um sieve and its oxide composition analysis was conducted using X-ray fluorescence (XRF) procedures. DoE method of mix design was used to produce concrete ingredi...
Wind energy is abundant, inexhaustible, affordable, environmentally preferable, and equally sustainable. More researches are emerging in the analysis of wind energy in Nigeria and each have proven that great potential exist for wind power generation in Nigeria but sufficient results is yet to be achieved in terms of application. The present research is intended to apply the technology of wind energy for pumping of water in rural Nigeria. To achieve this, a Savonius vertical axis wind turbine ...
Human necessities are increasing day by day where as the factories are running out of resources. To ameet these demands industries need to improve the quality and quantity of their production. Programmable logic controllers (PLCs) have been used for many decades for standard control in industrial and factory environments. Over the years, PLCs have become computational efficient and powerful, and a robust platform with applications beyond the standard control and factory automation. This pa...
