Remote seismic nodes frequently experience failure because of the short lifecycle of lead–acid batteries. Even the use of solar cells is insufficient because these cells have low energy conversion and requires the deployment ...

In Botswana crop production has been the most vulnerable component of the agricultural sector due to its heavy reliance on rainfed agriculture. At the same time, the availability of rainfall is uncertain due to natural ...

Lepidopteran stemborers are key destructive insect pests of cereal crops in sub-Saharan Africa with the indigenous noctuids Busseola fusca (Fuller) and Sesamia calamistis Hampson and the exotic crambid Chilo partellus ...

The increase in the number of linked technological devices, coupled with devices with new multimedia based services has resulted in the growing demand for high data rate communication and a spectrum crisis. Non-orthogonal ...

The open nature of radio propagation enables ubiquitous wireless communication, which allows seamless data transmission. However, unauthorized users may pose a threat to the security of the data being transmitted leading ...

Plasmids are extra-chromosomal mobile DNA elements found in bacteria, and often serve as vectors for accumulation and transfer of antibiotic resistance genes (ARGs) within bacterial populations in different environments. ...

Internal erosion and development of seepage pathways is an ever present concern in earth fill dams, and are a major reason for many dam failures. Internal erosional progresses that are responsible for many dam failures are ...

The explosive growth of biological sequences over the last decade has consequently led to a lot of research on effective techniques for storing and analysing this big data. Generating Deoxyribonucleic Acid (DNA) sequences ...

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 ...

Parental magma composition to layered ultramafic to mafic intrusions are commonly studied using rocks occurring along their contact with the surrounding country rock. These include sills, dykes and/or rare chill margins. ...
