The paper introduces mathematical models of a skid steered mobile platform for robotics. The platform consists of a rectangular steel construction with four wheels. Two banks of two drive wheels on each side are linked to two DC electrical motors via chain on sprocket drive and gearing. The two drive assemblies for the left and right banks are identical but they operate independently to steer t...

The use of retention gifts in clinical trials has been controversial, with some ethicists maintaining that such gifts represent undue inducement to the trial participants. A study was conducted at TREAD Research, a site-managed organisation based at Tygerberg Hospital, in which 302 participants completed a questionnaire that focused on their opinion with regard to such gifts. The results sugges...

It has been observed that denoising of ECG is done in stationary condition i.e. when the patient under scanner is lying on bed or in rest condition. This is very common case and the noise added in this condition can be removed by many different methodologies like FFT, wavelet, ICA etc. However, when the ECG is monitored in dynamic condition e.g., on tread mill testing, the noise inserted due to...

Several studies have been proposed to adopt memory prefetching schemes to reduce performance impact of long latency memory operations in GPUs. By leveraging a simple intuition that the consecutive warps are likely to have spatial locality, prior approaches prefetch two or four consecutive cache lines when there is a cache miss. Other approaches predict striding accesses by detecting base addres...

Maternal stress during pregnancy affects negative impact on health of offspring. In the present study, we compared the effects of maternal treadmill exercise and offspring treadmill exercise on prenatal stress-induced apoptosis and serotonin expression in offspring. Stress to the pregnant rats was induced by exposure of maternal rats to the hunting dog in an enclosed room. Exposure time was 10 ...
