ABSTRACT This study tackles two concerns of knowledge engineers in designing and developing a fuzzy rule-based expert system (FES). First is to acquire a knowledge-base that emulates human perception of application domain concept in order to avoid sharp boundary problems. Second is the need for modelling a comprehensive fuzzy rulebased expert system which eliminates redundant rules in order to solve the problem of rule-base unwieldiness and provide for knowledge-base instant updates. This th...
ABSTRACT A number of research efforts had been devoted to forecasting stock price based on technical indicators which rely purely on historical stock price data. However, the performances of such technical indicators have not always satisfactory. The fact is, there are other influential factors that can affect the direction of stock market which form the basis of market experts’ opinion such as interest rate, inflation rate, foreign exchange rate, business sector, management caliber, inves...
ABSTRACT The major aim of this work is to develop an efficient and effective k-means algorithm to cluster malaria microarray data to enable the extraction of a functional relationship of genes for malaria treatment discovery. However, traditional k-means and most k-means variants are still computationally expensive for large datasets such as microarray data, which have large datasets with a large dimension size d. Huge data is generated and biologists have the challenge of extracting useful ...
ABSTRACT This study uses advanced communications and computing technologies to support health care delivery and education. The automated e-Health-based system was designed to eliminate clumsy and tedious treatment procedures associated with manual treatment processes prevalent in care centres, especially in the developing countries. The operations support functionalities of the system are provided within a formal framework to eliminate system errors, improve dependability and enhance its usa...
ABSTRACT The ability of a system to meet the stated requirements affects the success and overall usability of the system. The presence of implicit requirements create difficulties in fulfilling the desires and needs of the stakeholders during software development. Identification of implicit requirements is essential to the functionality of the software as implicit requirements are equally as important as explicit requirements. Although different researchers and practitioners have identified ...
ABSTRACT Conventional grid-enabled portal designs have been largely influenced by the usual functional requirements such as security requirements, grid resource requirements and job management requirements. However, the pay-as-you-use service provisioning model of utility computing platforms mean that additional requirements must be considered in order to realize effective gridenabled portals design for such platforms. This work investigates those relevant additional requirements that must b...
ABSTRACT An Institutional Repository is essentially a web application that is capable of capturing, preserving and disseminating the intellectual output of a University or research institution in digital formats. The advent of the Mobile Web has ushered in a new wave of mobile devices - with multi-touch facilities and thus there has been a shift from Web access to Mobile Web access. This has brought about the need to make web applications accessible via mobile devices. This study investigate...
ABSTRACT The volume of information available on the Internet and corporate intranets continues to increase along with the corresponding increase in the data (structured and unstructured) stored by man organizations. In customer relationship management, information is the raw material for decision making. For this to be effective there is need to discover knowledge from the seamless integration of structured and unstructured data for completeness and comprehensiveness. This study addresses tw...
ABSTRACT Voice-enabled e-Education system is the enabling technology that allows users to access Learning resources on a web using a telephone. Telephony applications in the area of education are developed mainly for the visually impaired to address the limitations of user interface of a mobile learner in accessing web learning resources. However, with the proliferation of learning resources on the web, finding suitable content (using telephone) has become a rigorous task for voice-based onl...
Abstract Fuzzy logic is a paradigm for an alternative design methodology, which can be applied in developing both linear and non-linear systems for embedded control. One of successful application that can use fuzzy control is liquid level control. This control system keeps developing from time to time to replace the ordinary system which applies mechanical functions in its control in order to improve the system reliability. In order to find the best design to stabilize the liquid level, the p...
ABSTRACT This study tackles two concerns of developers of Tourism Information Systems (TIS). First is the need for more dependable recommendation services due to the intangible nature of the tourism product where it is impossible for customers to physically evaluate the services on offer prior to practical experience. Second is the need to manage dynamic user requirements in tourism due to the advent of new technologies such as the semantic web and mobile computing such that etourism systems...
ABSTRACT The University Course Timetabling Problem (UCTP) is a combinatorial optimization problem which involves the placement of events into timeslots and assignment of venues to these events. Different institutions have their peculiar problems; therefore there is a need to get an adequate knowledge of the problem especially in the area of constraints before applying an efficient method that will get a feasible solution in a reasonable amount of time. Several methods have been applied to s...
ABSTRACT Student and computer interaction becomes more salient where visual-auditory hardware and materials are required in classroom environment which are used for formal education. For instance, as a substitute of having classes during sessions, students learn mostly outside the class, by reading, watching videos and listening to podcasts or other audio format. Adaptive flipped classroom model is a learning and teaching approach that inverts the traditional classroom, in other words activi...
Abstract Malaria is one of the planet's deadliest diseases and one of the leading causes of sickness and death in the developing world. Africa has suffered and is still suffering from the adverse socio-economic effects of malaria; It is intimately connected with poverty. Judged as both a root cause and a consequence of poverty, it is most intractable for the poorest countries in the world. According to GSK’s (GlaxoSmithKline) Corporate Responsibility Report 2007, it affects the health and...
The increasing advancement in technology is creating new opportunities that can be incorporated in learning especially in institutions of higher learning. Majority of stakeholders in the institutions of higher learning, preferably the lecturers and students possess smartphones and computers as well as active social media accounts. The increased usage of social media coupled with the necessity to interact with people all over other would is posing a challenge to integrate social media into lea...
