Sub-Saharan Africa is currently the most homophobic place in the world in terms of both state institutions and public opinions. Many scholars have blamed this on the former colonial powers of Africa who imposed homophobic policies on their landholdings. In order to explain variations in African homophobia, this study conceptualizes homophobia in two forms: institutional, using a measure of the ...

This paper presents a new version of an EMG-based, hands-free, cursor control system, and compares its performance to that of a previous version. Both systems use classification algorithms that rely on the periodogram estimation of the power spectral density (PSD) of electromyogram (EMG) signals from muscles in the face. The older system requires three electrodes for EMG input, and utilizes an ...

C urrent controversies over presidential power suggest. that significant separation of powers depends on the existence of some effective counterweight to the executive ruler, which in turn presupposes a disposition to restrain the ruler that does not come from the ruler himself. One might conclude that schemes for separation of powers grow out of either a fundamental opposition to ruling or at ...

A theory based renewable energy sources course was complemented with seven hands-on laboratory experiments. The course was designed for engineering and non-engineering undergraduate students and did not require any advanced mathematics or physics background. Each laboratory experiment introduced a miniature version of an energy conversion device that mimicked the insights and workings of a real...

Myoelectric prostheses are generally not provided in the United Kingdom for children before the age of 3 1/2 years. Following the introduction of a smaller sized electric hand in the United Kingdom in 1993 the authors decided to introduce electrically powered hands for a group of congenital upper limb deficient children at a much younger age compared to normal practice. Eleven children were int...

The first triboelectric-nanogenerator (TENG)-based self-powered implantable drug-delivery system is presented. Pumping flow rates from 5.3 to 40 µL min-1 under different rotating speeds of the TENG are realized. The implantable drug-delivery system can be powered with a TENG device rotated by human hand motion. Ex vivo trans-sclera drug delivery in porcine eyes is demonstrated by utilizing the ...

Based on the ergonomics evaluation of existing non-powered hacksaws with original/horizontal and conventional/market handles, ergonomically designed hacksaw handles are proposed. To accommodate the entire male and female populations, the hand dimensions are categorized into three groups: small, medium and large. The proposed handles give special emphasis to hand size, length, cross-section dime...

introduction: brain computer interface (bci) systems based on movement imagination (mi) are widely used in recent decades. separate feature extraction methods are employed in the mi data sets and classified in virtual reality (vr) environments for real-time applications. methods: this study applied wide variety of features on the recorded data using linear discriminant analysis (lda) classifier...

philosophers from one hand take the “al-vahed” axiom for granted, and on the other hand, they assume that the almighty to be of absolute power. now the question is whether: this is at odds with the “al- vahed” axiom? how can we accept at the same time the absolute power of the almighty and the “al-vahed” axiom? we should say here: majority of philosophers, mystics and kalam specialists have cla...
