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...
Rampant cyber incidences in Kenya targeting banks call for mediations beyond existing cybersecurity principles. This quantitative study sought to collate multi-domain variables from previous works to develop a framework for measuring cyber-resilience in Kenyan banks known as the Cyber-resilience Framework for Banks (CRF4Banks). The framework consists of eight key cyber-resilience constructs and their constituent variables, identified from empirical research and literature. Cyber-resilien...
This study sought to assess the existing state of Waste Electrical and Electronic Equipment in Kenya, to improve on the methods of disposal, recycling, and facilitation of a circular economy by households through the use of ICT. The study was driven by the following objectives on how they influence a circular e-waste economy; sociodemographic factors, consumer behaviour, level of access to information and ICT infrastructure. The target population for the study was households within Nairobi Co...
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...
Light-Emitting Diodes (LEDs) are used in a variety of devices ranging from watches to solar home systems, as status indicators or communicative tools. They are typically designed to produce light in different colors andintensities. However, the communicative output varies across devices of similar or different functions. This variation and the sense that there is a wide array of expressions that can be employed, makes it hard for users of the devices to deduce the feedback easily. This rese...
ABSTRACT Commercial banks face severe concerns over mobile banking security issues due to substantial monetary losses on customers’ accounts. Most customers of commercial banks in the Democratic Republic of Congo have been losing vast amounts of money from their accounts to fraudsters and hackers, who are taking advantage of weak security controls. This has necessitated the present study to be conducted by proposing a mobile banking security framework based on Octave-small approach for com...
ABSTRACT The rapid increase of smartphone proliferation in Kenya has resulted in users being dependent on their phones for everyday activities. This increased interaction with smartphones has posed a significant threat to users’ privacy and security. The exposure to threats demonstrates a need to understand users’ security awareness and behavior when using their mobile phones. Therefore, this study sought to establish the level of security risk awareness and user behaviour among smartpho...
The power consumption of physical and virtual machines is a major challenge for small to large scale cloud computing data centers. Tow states of the virtual machine, active state if selected by cloudlet and idle state ifnot selected. Two typed of works applied which are existing work and proposed work. In existing work non-power aware data center, the power consumption used time-shared data center that discarded cloudlet file size to selected VMs. To performance enhanced of power consu...
