Computers are one of the most popular kinds of electronic devices in the world today. Whether kid or adult, male or female, everyone wants to learn how to operate the computer. People use computers for different purposes such as typing papers, creating websites, making presentations, browsing on the internet, playing games, etc. In fact, many people are still confused about choosing what kind of computer they want to buy. In the world today, there are two types of computers: notebook/laptop a...
According to the U.S. Census "Forty-four million households, or 42 percent, had at least one member who used the Internet at home in 2000" (Home Computers 2). Today, no doubt, even more family members in the United States use computers. Most people are aware of the desktop computers which can be found in the home and in the workplace. What are the different types of computers and what are their purposes? Computers can be classified into three different categories of home computers, portable c...
ABSTRACT The on-going fusion between Computer education and mass media has transformed the world in which we live into a “global village” where students can easily get in touch, see or speak to one another and exchange information is multimedia, electronically, from any point on the globe to another. This important development of computer education has been acknowledged as the practical tool for national development. This paper examines ways to enhance computer education through the a...
AbstractThis work titled The Role of Chemistry Teacher in the Development of Science Education in Nigeria is specifically designed to find out and discuss the various ways science education has been lagging in Nigeria and how chemistry education can help to remedy the situation. In the course of this, some issues were discussed such as the concept of chemistry, chemistry education, science education, objectives of chemistry education, problems facing science education in Nigeria and ways to...
BACKGROUND OF STUDY Chandrasekhar (2001). Information Communication Technology are defined, for the purposes of this primer, as a “diverse set of technological tools and resources used to communicate, and to create, disseminate, store, and manage information.” These technologies include computers, the Internet, broadcasting technologies (radio and television), and telephony. Information and communications technology is often used as an extended synonym for information technology , but...
What is computer? Computer can be defined as an electronic device that operates under the control of instruction that is installed in its memory units. It can also mean an electronic device that receive data as an input, process and bring out the result as an output. With the definition above, one can understand that computer is just a device (electronic device) which operate and control other parts. What is computer system? Computer system like any other system is the combination of interna...

Biometrics is seen by many as a solution to a lot of the user identification and security problems in todayUs networks. Password abuse and misuse, intentional and inadvertent is a gaping hole in network security. This results mainly from human error, carelessness and in some cases maliciousness. Biometrics removes human error from the security equation. Our project will examine all the technological and feasibility aspects as well as the practical applications. Biometric systems allow ...
Abstract This study investigates the Effect of Computer- Instructional Package (COMPUTER INSTRUCTIONAL PACKAGE) on the Performance of Senior Secondary Students in Quadratic Equation in Bida Educational Zone of Niger State, Nigeria. The study examined the significant of performances of students thought using computer instructional package andLecture method. The sample consisted of 120 senior secondary school students drawn from four secondary schools. Stratified random sampling was used to se...
ABSTRACTCarbon –U (C-11) radiotracers are widely used for the early diagnosis of cancer, monitoring therapeutic response to cancer treatment and pharmacokinetic investigations of anticancer drugs. PET imagining permits non-invasive monitoring of metabolic processes and molecular targets, while carbon-II radiotracers allow a “hot-for cold” substitution of biological active molecules. Advance in organic synthetic chemistry and radiochemistry as well as improved automated techniques for ra...
ABSTRACT. In this paper, we present and analyze a cholera epidemiological model with control measures incorporated. This model is extended from the one proposed in [16] by including the effects of vaccination, therapeutic treatment, and water san- itation. Equilibrium analysis is conducted in the case with con- stant controls for both epidemic and endemic dynamics. Opti- mal control theory is applied to seek cost-effective solution of multiple time-dependent intervention strategies against ...
ABSTRACT In this paper, a non–linear mathematical model is proposed to study the effects of irresponsible infected immigrants on the spread of HIV/AIDS in a heterogeneous population with a constant recruitment of susceptible receptors. Theequilibrium points, stability analysis, and numerical solution on the model are presented. The Routh–Hurwitz stability condition was employed to examine the stability of the disease– free equilibrium and Next Generation matrix was adopted to g...
Abstract Data Stream Mining is one of the area gaining lot of practical significance and is progressing at a brisk pace with new methods, methodologies and findings in various applications related to medicine, computer science, bioinformatics and stock market prediction, weather forecast, text, audio and video processing to name a few. Data happens to be the key concern in data mining. With the huge online data generated from several sensors, Internet Relay Chats, Twitter, Face book, Online B...
Abstract Pattern recognition is seen as a major challenge within the field of data mining and knowledge discovery. For the work in this paper, we have analyzed a range of widely used algorithms for finding frequent patterns with the purpose of discovering how these algorithms can be used to obtain frequent patterns over large transactional databases. This has been presented in the form of a comparative study of the following algorithms: Apriori algorithm, Frequent Pattern (FP) Growth algorith...
Abstract Concepts like gentelligent products, smart objects or cyber-physical systems have already proven a high potential especially for decentralized production planning and control. In this context, decentralized communication, new sensor technologies and the increased application of simulation and monitoring systems lead to an enormous increase of manufacturing data. Additionally, a new approach for the assessment of manufacturing quality based on process signals from the machine tool is ...
