Abstract: Since the integration of technology in teaching and learning, it has been observed that there is improvement in the acquisition and retention of knowledge. There is also existing body of research on adoption of e-learning platforms by students in institutions of Higher Education across the world. However, few of the existing studies has involved students in private tertiary education institutions in Botswana. Therefore, this study has set out to explore student usage of e-learning ...
Abstract: Increase in global population places a demand on fuel and protein sources therefore putting a strain on their supply. The demand for fuel products is currently met by increased usage of fossil fuel, a nonrenewable energy source. However, burning of fossil fuel has challenges such as the release of greenhouse gases associated with negative environmental impacts. To overcome these challenges, attention has been given to renewable energy sources as biodiesel, a biofuel that has...
Abstract: Abstract The purpose of this study was to reviews the effects of the technology acceptance model on internet banking adoption at Barclays bank, Tsabong (Botswana). The primary objective of the study was to investigate the factors which influence the customer‟s behavioral intention to accept internet banking. This research adopted a descriptive research design, following a survey design strategy. A positivism research philosophy was adopted, where the data collection was done foll...
Abstract: In the world, the man matters, not the machine, people need to be care, not data. There is transition from information technology to human technology. The answer is internet of everything (IoE). The int ernet of everything (IoE) is a concept that extends the internet of things (IOT) by encompassing the machine-to-machine (M2M) communication, machine-to-people (M2P) and technology-assisted people-to-people (P2P) with expended digital features. It includes different types of devices,...
Abstract: Traditional frequent itemsets mining (FIM) suffers from the vast memory cost, small processing speed and insufficient disk space requirements. FIM assumes only binary frequency value for items in the dataset and assumes equal importance value for items. In order to target all these limitations of FIM, high-utility itemsets (HUIs) mining has been presented. HUIs mining is more complicated and difficult than FIM. HUIs mining algorithms spend more execution time because of large searc...
Abstract: Antimicrobial resistance (AMR) is regarded as a global health threat, characterized by rising resistant bacteria and rapid development of resistance genes to existing antibiotics used in clinical and veterinary settings. AMR has negative impacts and affects human, animal, and the environment. In Botswana, Africa, AMR is not well understood, particularly in rural settings with poor sanitation. The misuse and overuse of commonly used antibiotics like ß-lactam antibiotics, combi...
Abstract: Strychnos is a widely varied genus from the Loganiaceae family with over 200 species identified worldwide. Most of these species are drought tolerant and used for many things such as food, medicine, tools, and ornaments. In Botswana, 7 Strychnos species have been reported, two of them (S. cocculoides and S. spinosa) have been declared as endangered. In this study, five Strychnos species were identified morphologically and through molecular genetics. Their distribution and abun...
Abstract: The Motloutse Complex to the southwestern margin of Zimbabwe Craton is a medium-grade terrane in northeastern Botswana. Some studies consider it as part of the Limpopo Complex high-grade terrane between the Kaapvaal and Zimbabwe cratons, while others argue it as an allochthonous terrane separate to the Limpopo Complex. A number of shear zones are postulated to delineate the extents of Motloutse Complex. Except the northern margin (the Shashe shear zone), the rest of the terran...
Abstract: In the healthcare system, the Internet of Things (IoT) based distributed systems play a vital role in transferring the medical-related documents and infor mation among the organizations to reduce the replication in medical tests. This datum is sensitive, and hence security is a must in transforming the sensational contents. In this paper, an Evolutionary Algorithm, namely the Memetic Algo rithm is used for encrypting the text messages. The encrypted information is then inserted int...
Abstract: Vehicle-to-Vehicle (V2V) transmission is utilized for most security-related programs targeting Vehicular Ad-hoc Networks (VANETs) to disseminate safety-related knowledge to nearby cars. However, the traditional broadcasting networks have broadcast winds, contributing to intolerable pauses in transmission and loss of packets. This paper proposes an important transmission scheme for distributing protection signals throughout the sensitive region called the Enhanced Probabilistic-b...
Abstract: Nowadays, when collecting data, it has become almost unavoidable to end up with missing data due to various reasons. Very often, these reasons are out of the control of the investigator. For regression settings, data can be missing in the response space, covariate space, or in both the response and covariate spaces. Such missingness can be related to different missing data mechanisms. The most commonly encountered missingness mechanisms in the literature include missing completely ...
Abstract: The bioecology of large branchiopods in Central District, Botswana, was analysed to determine if genetic relatedness or environment of origin determined the thermal physiology of large branchiopods. Two temporary wetland types (Rock-pools and Pans) were identified and their thermal conditions characterised. Temperatures experienced in each wetlands type were measured for synchronised periods spanning both dry phases and hydroperiods of the temporary wetlands. Anostraca and Spinicau...
Abstract: Lemmatization is an important task which is concerned with making computers understand the relationship that exists amongst words written in natural language. It is a prior condition needed for the development of natural language processing (NLP) systems such as machine translation and information retrieval. In particular, Lemmatization is intended to reduce the variability in word forms by collapsing related words to a standard lemma. There is a limited research on lemmatization o...
Abstract: In this thesis, we use the theory of minimal Sullivan models in rational homotopy theory to study the partial computation of the Lie bracket structure of the string homology on a formal elliptic space. In the process, we show the total space of the unit sphere tangent bundleS2m−1 → Ep→ Gk,n(C) over complex Grassmannian manifolds Gk,n(C) for 2 ≤ k ≤ n/2, where m = k(n − k) is not formal. This is done by exhibiting a non trivial Massey triple product. On the other hand, l...
Abstract: We introduce the exponentiated odd Nadarajah-Haghighi-G (EO-NH-G) family of distributions and the exponentiated odd exponential Topp-Leone-G (EOE-TL-G) family of distributions as well as the exponentiated odd exponential Topp-Leone-G power series class of distributions. We obtain the series expansions of the probability density functions, hazard rate functions, quantile functions, moments, conditional moments, Bonferroni and Lorenz curves, Renyi entropy and distribution of order st...
