ABSTRACT This research work focus on the evaluation of water-based eggshells powder as a quenching medium for hardening medium steel. Medium carbon steel sample with original diameter of 12.00mm and gauge length of 50m was quenched in both the agitated and non-agitated water-based eggshell powder quenchant. The medium carbon steel samples were initially normalized and […]

ABSTRACT The paper contains the design, construction and testing of a parabolic reflector system. Using concentrating collector, the rays from sun is concentrated at the focus point of the reflector in which different experiments are carried out to estimate the temperatures at the focal point. It also describes the sun tracking system unit by keeping […]

ABSTRACT A TD 110-TD 115 single cylinder four-stroke compression ignition engine test bed, and  incorporated with a hydraulic dynamometer  was used to conduct the engine performance analysis to study the influence of marula oil methyl ester (MOME)- diesel fuel(DF) on engine performance The engine performance experiments of  DF samples  and MOME –DF blended fuel samples; […]

ABSTRACT Tracking is a process of determining current and past locations of a unique item or property. It is used to detect and locate targets when they moved and report new position. Another approach is to report the arrival or departure of the object and record the identification of the object, the location where observed, […]

ABSTRACT The design steps of cellular manufacturing systems (CMS) are usually performed sequentially without considering interactions between stages. There needs to be a certain feedback among different parts of CMS design so that the system can be designed simultaneously for a better functionality. In this paper, an intuitive approach to eliminate congestions in CMS was […]

ABSTRACT Heavy duty tasks such as engine replacement and dropping, involves engine rebuilds or upgrades, repairs, engine bay rehabs, and other complex operations that involves the movement of heavy engine parts in the workshop from one place to another. The entire process usually takes time depending on the hoisting device employed. For example, chain hoist […]

ABSTRACT In data-mining, many algorithms can’t process continuous value, so, discretization is an important method in data-mining application. Discretization describes converting some continuous data into some discrete values. In our paper firstly, we will try to implement three discretization techniques on a dataset, namely, Equal Width, Global Equal Width and Equal Frequency. Secondly we will […]

ABSTRACT A motorized tuber chipping machine was designed, constructed and tested for its efficiency using yam and cassava tubers. The purpose is to reduce the thickness and increase the surface area thereby improving drying. It consists of rotary blades, feeding chutes and electric motor. It is powered with the aid of a 2hp, 1800 rpm […]

ABSTRACT In this study aim to investigate traditional mud brick has been used in South of Turkey. The population in the rural area of Turkey has been increased due to back to village project of Government. Most of the buildings in the area made out of limestone and adobe. But this material is not sufficient […]

ABSTR This paper proposes an improved Two Phase Clocked Adiabatic Static CMOS logic (2PASCL) circuit. The proposed circuit is based on energy recovery adiabatic principle which consumes less power. The number of transistor required in proposed circuit is same as that of reported 2PASCL. Various combination circuits such as inverter, NAND, NOR, XOR has been […]
