ABSTRACT Security is a very vital factor for human growth and development. It has also become a major recent issue in buildings and especially, school buildings. Ensuring security in buildings is a collective endeavour with each individual, government, organization, and community having its own role to play. The architect, who is the master builder, is chiefly responsible in ensuring that the built environment meets requirements of security. This report studied the various techniques of ach...
ABSTRACT A number of phenomena in modern science can be conveniently described in terms of problem for hyperbolic equation with Carleman estimates to the solution of inverse problem. The purpose of this study is to give a survey of the solution of the inverse problems for hyperbolic equation by Carleman estimates. We extend the results and prove the Carleman estimate focusing on an inverse problem for a simple hyperbolic equation. Also we derive the Lipschitz's stability by energy estimate; w...
ABSTRACT Geophysical survey techniques have successfully been applied to near-surface limestone detection in karstic terrains. A magnetic geophysical survey to delineate the karstic structure of the Nyanda Mountains, Masvingo, was carried out in the interest of mapping out limestone deposits required for cement production. The magnetic-total-field-anomaly maps helped reveal the metamorphic and sedimentary units in the study area. Although only part of the mountain range was surveyed for this ...
Among other atmospheric region, ionosphere, which is the ionized region of the atmosphere, is considered to impose serious limitation on radio wave transmission while the effect of other layers, more especially, the troposphere is often treated as negligible. At higher frequency, radio waves pass through the ionosphere and are attenuated due to the free electrons present in it. However, recent studies have shown that while the ionospheric disturbances can be predicted on a global scale, trop...
This study explores the threats of climate change on agriculture and food security globally, focusing on Nigeria. Nigeria, as the most populous country in Africa, is highly vulnerable to the impacts of climate change on its agricultural sector. The research conducts a comprehensive literature review and synthetic analysis to identify the key factors that make Nigeria's food production systems susceptible to climate change. Nigeria's diverse climate, influenced by latitude, topography, win...
ABSTRACTNew interactive computing applications are continually being developed in a bidto support people’s changing work and recreational activities. As research focuses on oneparticular class of interactive systems, high level models of interaction are formulated andrequirements emerge that reflect shared features or common functionality among those systems.Within this seminar a new class of interactive syst...
Computer is a machine that is invented and developed by mimicking the functionality of the human brains. Several human abilities are utilized in writing the programs that run this excellent device. As a result the computer could be applied to solve virtually all problems of man (except spiritual problems).My question is: "Would it not be very beneficial to be educated on how to use this problem solving device?"
ABSTRACT Empirical investigations on students’ conception of cell division in Biology indicated a major misunderstanding of some scientific concepts even after being thoroughly taught. Therefore the main aim of this study was to investigate the impact of computer-based instructional simulations in the teaching and learning of cell division. The target population was the form two Biology students of the Seventh Day Adventist Senior High School, Asokore, Koforidua. Two Home Economics c...
ABSTRACT Traditionally, the concept of teaching mathematics has always been a teacher – student relationship; in which the teacher explains the concept of the topic to the student and illustrates it with some examples. The student is then left to understand the topic on his or her own using the tools given by the teacher. A problem often results when the student needs a guide while practicing and the teacher is not available. In that case, learning becomes slow and hindered. As we are in a ...
ABSTRACT This study sought to investigate the challenges of information and communication technology integrated in education in Nakuru County, Kenya. This was following the ministry of education emphasis on adoption of electronic learning in educational institutions. While this policy is being implemented, the problem facing it is the slow up take of ICT integration in secondary school education. The specific objectives of the study were to: analyze the students‟ enrolment rate of computer ...
ABSTRACT Cloning of Computer System is very essential in a computing area. This project focuses more on how computer system could be coupled and maintained effectively and efficiently without any fault during assembling of the system. Throughout this project we shall focus on each and every components needed for assembling and also there functions. The main reason why people go for assembling of system instead of buying a new system is to allow them to have good and satisfactory q...
Dell Computers was founded by Michael Dell, who started selling personal computers out of his dorm room as a freshman at the University of Texas. Michael Dell would buy parts wholesale, assembled them into clones (exact replicas) of IBM computers, and sold them by mail order to customers who did not want to pay the higher prices charged by retailers. Michael Dell was soon making 80,000 dollars a month profit and in 1984 Michael dropped out of university to found Dell Computers. Michael formed...
ABSTRACT Spinal Tuberculosis is considering the most clinically important extra pulmonary form of disease. Early recognition is therefore necesaary to minimize residual spinal deformity and/or permanent neurological deficit. In this study we intended to Evaluate the CT and MRI images, morphology of spinal TB and correlated the imaging features of these two modalities. A total of 30 patients, (CT:10 patients) and (MRI: 20 patients) images were retrospectively analyzed in 30 patients with prove...
ABSTRACT Plain abdominal radiographs are commonly requested for acute medical emergencies on patients with non-specific abdominal symptoms and signs. Whether plain abdominal radiography contributes to therapeutic decision making or disposition remains questionable particularly in the case of a negative result, the additional value of plain abdominal radiographs most especially in emergency situations is disputed. The study is a retrospective research design aimed at evaluating the common ...
Computers have become a way of life for today’s high society. Many aspects of modern life that we have come to accept as common place would not be possible if there were no computers. Today computers are use extensively in many areas of business, industry, science, education etc. The major advantage of computer is its speed that makes it able to give some useful information very quickly. This speed also opens new approaches to problem so...
