The effect of particle size of date palm seed ash (DPSA) on concrete properties was investigated through the use of different fineness of date palm seed ash (600um, 300um, 150um and 75um) at 2.5% replacement of cement with date palm seed ash and tested for compressive strength at 7, 21, 28 and 56 days curing duration. The consistency and setting times of cement-DPSA paste was also researched to determine the amount of water required to prepare hydraulic cement paste for testing. The date palm...
The suitability of palm kernel shell as a partial replacement of fine aggregate in concrete was researched to verify if concrete made with palm kernel shells meet some minimum standard prescribed for strength and density. Based on British standard classification of fine aggregate as aggregates passing the number 4 sieve of 4.75mm size or slightly higher sizes depending on local requirement, crushed palm kernel shells of particle diameter not greater than 5.0mm was used to replace river sand a...
In this paper, the simplicity of the convectional Histogram in-motion mapping for obstacle avoidance technique which is now modified and modeled to Hybrid histogram in-motion mapping (HHIM) for autonomous mobile robot navigation and obstacle avoidance was primarily developed by AKWARA UCHENNA C. to solve robot navigation problems for completely unknown environment particularly for a static wave concave shaped obstacle. The developed model is to address the problem associated with a static wav...
In this paper, the research study on velocity heat conductivity (VHC) model for two autonomous mobile robots in energy workspace is adopted. The model is applied to solve and address; the conversion of heat energy conductivity into kinetic (internal) energy conductivity of the robots, to obtain the velocity energy placement and to derive a velocity heat conductivity mathematical model for algorithm simulation drive using specific heat capacity and thermal diffusivity response in energy worksp...
In this paper, the research on virtual force vibration concept for four resonance autonomous mobile robots navigation is welcome. This concept is adopted and applied to solve and address; the behaviour of four autonomous mobile robots without initial force of vibration, the amplitude frequency of the vibrating medium, the effect of inapplicable resonance, the wavelength of vibration and the vibrating amplitude length of the four mobile robots. Robot 1 is set into motion at an amplitude freque...
In this paper, the virtual thermodynamic temperature concept (VTTC) proposed for 2D obstacle environment for autonomous mobile robot is welcome. The concept emphasis on the heat transfer and temperature measurement of an obstacle and robot workspace with reference to the virtual target concept (VTC) for Lengthy, Concave and Wave concave shaped obstacle. This method is used to address the heat transfer (internal) and the temperature incremental area that occur in 2D workspace for autonomous ...
TABLE OF CONTENT Definition of Bearing Various types of Bearing and Features Classification of bearing Uses of types of bearing Criteria for bearing selectio DEFINITION OF BEARING A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as well as by the directions of applied loads they can handle.
TABLE OF CONTENT Introduction Brake System Types of Brake System Applications of Brake System Performance Parameters of Brake System INTRODUCTION A brake is a device which inhibits motion. Its opposite component is a clutch. The rest of this article is dedicated to various types of vehicular brakes. Most commonly brakes use friction to convert kinetic energy into heat, though other methods of energy conversion may be employed. For example regenerative braking converts much of the energy to e...

A clear insight into the affinity of biochar towards water is critical for its intended application. The state of the biochar would govern its use for a particular application. For example, hydrophilic biochar is preferred when sorption or organic contaminants are concerned. It is, at present, not clearly established the factors that govern the hydrophilicity and/or hydrophobicity of a biochar. Comprehension of the factors that affect the affinity of biochar towards water would aid to create ...
African locust bean is a leguminous plant that is rich in nutrients and is used as food condiment. The traditional method of processing this food condiment is mostly unhygienic; consume a lot of fire wood, human energy and time. Using traditional methods for boiling 33.7Kg of locust bean would take about 12 hours. This study attempts to mechanize the existing traditional methods of boiling locust bean by designing, constructing, and evaluating electrically powered locust bean boiler. The...

Nowadays, consumption of rice is increasing that leads to the greater demand in the production of it. After harvesting and shelling, husk remains and comes in great volume. Thus this rice husk is one of the big problems to be considered. Some studies suggested a solution to put rice husk ash as partial substitute to cement in concrete mixing in order to minimize the large quantity of rice husks build up as time goes by. Reinforced concrete is concrete in which reinforcing bars or other typ...
Impact of Information and Communications Technology (ICT) in Northern Nigeria: Ojie Moses Okim Department of ICT Cross River State University, Cross River Abstract The main constraints to the use of information and communications technology (ICT) in Northern Nigeria are identified, argued and related to the setting up of a common computerized system based on the National Bureau of Statistics’ (NBS) report which places mostly northe...
ABSTRACT The Student Industrial Working Scheme (SIWES) is a program that was designed by the Industrial Training Fund (ITF) with the aim of aiding young science and engineering university students to have an experience of working in industries and companies based on their fields of study in order to extend their learning outside the classrooms and lecture halls. This is a report which contains information about my SIWES experience. It contains details on the company I worked in which wa...
