With the growth of the Internet and the increase in number of online devices, IPv4 address space approaches exhaustion. This has led to the deployment of IPv6. However, IPv6 has not been widely adopted, particularly in Kenya. According to Akamai (2016) IPv6 has an adoption rate of 0.02% in Kenya despite recent studies showing that adoption is increasing in some parts of the world. Some of the shortcomings of the current methods of measuring IPv6 adoption are: (a) There is limited informa...
ABSTRACT A study was carried out to assess the safety of selected vegetables grown in urban areas, focusing on a case of heavy metals in Dar es salaam, Tanzania. The study investigated the concentration of three heavy metals, namely Lead (Pb), Cadmium (Cd) and Copper (Cu) in the edible portions of selected leafy vegetables, and the effect of blanching on the possible reduction of heavy metals concentration. The study also compared the levels of metal in selected matured leafy vegetables acro...

Word processors are one of the most widely used software applications in our time and have greatly contributed to the shift of paperless office. It has brought drastic changes in the way business documents are created, edited and stored. However word processors have over the years proven to be susceptible and have been successfully exploited to launch catastrophic attacks which have been costly to various states (countries), organizations and individuals. The main objective of this resea...
E-learning has enhanced the way students think and learn over time. Different studies show that students appreciate facilities offered through the e-learning process. It has also proven to be a very useful tool by bringing education closer to the learner, hence, learner-centred. A point to note about e-learning is the ability to offer a wide range of information access, storage and education curriculum. Institutions of higher learning moderate and harmonize this information between instr...
Abstract The major lithostratigraphic units of the eastern Dahomey Basin are the Araromi, Ewekoro and Akinbo Formations. Field studies show that the Araromi and Akinbo Formations contain shaly facies, while the Ewekoro Formation contains essentially fossiliferous limestones. The Araromi shales are dark and bituminous, while those of the Akinbo are fissile and concretionary. Selected subsurface and outcrop samples of these lithotypes were analysed to ascertain their palaeodepositional environm...
The proliferation of Android smartphones has propagated negative societal issues that resulted in successful arrests of the culprits, forensic examination and prosecution. Other such cases have collapsed due to alteration of forensic evidence as a result of inadequate forensic sound frameworks. The purpose of this study was to develop and evaluate an enhanced forensic framework for Android smartphones with a key focus on data integrity. The research objectives included exploration of roo...

ABSTRACT Using multiple enrollment can improve recognition performance in fingerprint recognition systems; but there are several technical and operational challenges to implementing multiple enrollment based fingerprint recognition systems. Multiple enrollment based fingerprint recognition systems still have low recognition accuracies, poor matching speeds, and consume a lot of memory making it difficult to implement them in real world scenarios. Also, most of multiple enrollment based finge...
