Abstract: The shovel-truck system is commonly used in open-pit mining operations. Truck haulage cost constitutes about 26% of open-pit mining costs as the trucks are mostly powered by diesel whose cost is escalating annually. Therefore, reducing fuel consumption could lead to a significant decrease in overall mining costs. Various methods have been proposed to improve fuel efficiency in open-pit mines. Case-based reasoning (CBR) can be used to estimate fuel consumption by haulage trucks. In ...
Abstract: Stringent accuracy requirements need to be met for eLoran deployment in marine navigation and harbour entrance and approach. A good accuracy model is therefore required to predict the positioning accuracy at the user’s receiver locations. Accuracy depends on the variations of additional secondary factors (ASFs) and the primary factor delay. The changes in the air refractive index caused variations in the primary factor (PF) delay of the eLoran signal, and current eLoran accuracy ...
Abstract: The load variation during three-point bending (TPB) tests on prismatic Nestos (Greece) marble specimens instrumented by piezoelectric sensors is predicted using acoustic emission (AE) signals. The slope of the cumulative amplitude vs the predicted load curve is potentially useful for determining the forthcoming specimen failure as well as the indirect tensile strength of the material. The optimum artificial neural networks (ANN) model was selected based on a comparison of different...

Abstract Several procedures have been proposed to overcome various challenges of product-content analysis after manufacturing and downstream automatad recycling pmcesws. These procedures have been restricted by factors such as the inabiiity to determine exactly the physical state of the hidden pm of End-of-Life products. This inhibition among others has rresldted into an explosion of solutions by researchers. This paper presents the initial investigations in the development of imaging softwa...
ABSTRACT A framework for condition monitoring approach that uses the sense of smell was investigated to diagnose the faults of plug-not-firing, loss of compression and carburetor faults from the exhaust fumes of gasoline fuelled automobile engine. An electronic nose based condition monitoring hardware and software was developed using the framework to obtain smell prints that correspond to normal operating conditions and various induced abnormal operating conditions. Fuzzy C-means and K means ...
ABSTRACT Usage of ergonomically unsuitable classroom chairs and desks promotes bad posture while bad postures affect students’ learning, performance and health. Attention is rarely paid to ergonomic fitness of classroom chair and desk used by primary school pupils in Nigeria up till now. This study investigated classroom furniture status in the Staff School, University of Ibadan, Oyo State, Nigeria and developed an automated procedure for designing ergonomically suitable chair cum desk mode...
Abstract Simulation of reliable solutions of nonlinear engineering problems by means of stable numerical algorithms is a frequent and acceptable practice. This study focuses the development and investigation of Range-Kutta coefficients dependent stability polynomial for the second, third and fourth orders Runge-Kutta schemes. The development utilized matrix inversion operation procedure that involves determinant and cofactors computation of relevant matrix. The validation was made referencin...
Abstract This research presents a conceptual procedure for characterizing the essential nature of the diagnostic reasoning process. This computerization of the medical neurological section of the University College Hospital Ibadan in Nigeria leads to effectiveness and efficiency of the existing medical diagnosing process. The main purpose of this project is to design a computerized brain diagnosing system that would be used in carrying out the daily diagnosing activity in the clinic. The dev...
ABSTRACT The One Laptop Per Child project has succeeded in developing a novel computer that is tailored to the particular needs of the developing world. The use of this example of a modern computer systems design challenge can be a valuable case study as a teaching tool in computer science. The OLPC laptop is a multiple-purpose computer that is rugged, low-cost, low-power, mesh networked, and inexpensive. An overview of the technology in the laptops is given, as well as curricula suggestions ...
A paper on Electronic Source Code Plagiarism Checker/Detection This paper covers a few algorithms used in an attempt to detect plagiarism among students’ computer program source codes electronically, that is, using a computer software program. One algorithm proved to meet most of the requirements with acceptable results and was implemented using VB .Net programming language. Keywords: plagiarism detection, source code, kheme, source code plagiarism detection, plagiarism detector, source...
ABSTRACT The rapid growth in the use of wireless communication in mobile network devices has made many engineers and researchers to start to look into ways to enhance data transmission either in form of voice, text, data, streaming multimedia, internet etc. Wireless Services that occur in real time require very little or no bit error during transmission in order for the receiver to get an intelligible information from the transmitting station. Whereas some services require more data to be tra...
INTRODUCTION:Many interconnection device are required in a modern network, from the interface that allows a single computer to communicate with other computers via a LAN cable or a telephone line, to the large and complex switching devices that interconnect two or more entire networks.
ABSTRACT In a developing economy like Nigeria financial resources are scarce commodity. Hence, cheaper means of accomplishing tasks even within the presence of scarce resources are always explored. This paper presents the design and implementation of a software intercom on local area network (LAN). The design provides a solution that eliminates the use of expensive hard-wired intercoms and Private Automatic Branch Exchange (PABX) by making use of only LAN and full multimedia computer allowing...
