Artificial Intelligence (AI) engineer, also commonly referred to as machine learning (ML) is a relatively new job category, which has been gaining increasing popularity.1 In fact, within the past few years, AI and ML engineers have started making top lists for most popular roles hire, though software full stack developer, product manager, architect still lead list.2

The creation of new technologies that serve humanity holds the potential to help end global poverty. Unfortunately, relatively little is done in engineering education to support engineers' humanitarian efforts. Here, various strategies are introduced to augment the teaching of engineering ethics with the goal of encouraging engineers to serve as effective volunteers for community service. First...

We described preliminary work on designing a “robot engineer”. Somewhat similar to the idea of a robot scientist, the robot engineer is a closed-loop system that designs tools for a robot, and even complete robots, that are tested in simulation, manufactured and realised using 3D printing. The artefact is then evaluated on real-world tasks, feeding back to the original design. The system builds...

Multiple-choice tests play a large role in determining academic and professional outcomes. Performance on these tests hinges not only on a test-taker’s knowledge of the material but also on his willingness to guess when unsure about the answer. In this paper, we present the results of an experiment that explores whether women skip more questions than men. The experimental test consists of pract...

Different scoring rules can result in the selection of any of the k competing candidates, given the same preference profile, Saari (2001). It is also possible that a candidate, and even a Condorcet winning candidate, cannot be selected by any scoring rule, Saari (2000). These findings are balanced by Saari’s result (1992) that specifies the necessary and sufficient condition for the selection o...

The current exposure limits of mineworkers to physical pollutants, under the Mine Health and Safety Act3 is 85 dB LAeq,8h, with a peak sound pressure level of 135 dB(A). However, the sound pressure level (SPL) of machines is generally determined according to the methods and procedures defined in SABS-ISO 3744 under free field conditions as defined in Appendix 3 of the same standard. While SPL a...

The hypothesis that thermal plumes contribute to the Cenozoic magmatism in East Africa is now widely accepted. The controversy lies on how many plumes exist and where they may be located. In this study we show numerical experiments of mantle convection models for a number of thermal plume models and discuss the implications for the melt generation in East Africa. We investigate how the plume(s)...

INTRODUCTION The desire for a child in Ethiopian society is normal. Among HIV positive women, due to the risk of MTCT, it is imperative to understand factors influencing women's desire for children. This study aimed at assessing factors associated with desire for children among HIV-positive women in two selected hospitals of Afar Regional State, Ethiopia. METHODS A facility based case-control...
