possible against the spread of the little ...
A cornerstone in the modeling of wireless communication is MIMO systems, where a complex matrix variate normal assumption is often made for the underlying distribution of the propagation matrix. A popular measure of ...
BACKGROUND : The assessment of fetal blood flow using Doppler waveform can be used to identify placental
insufficiency, and hence is a tool to identify fetuses at risk of stillbirth due to fetal growth restriction (FGR). ...
BACKGROUND : South Africa is experiencing an increasing burden of cardiovascular diseases, including coronary heart disease (CHD) and stroke. We aimed to obtain overall national prevalence estimates of CHD and stroke in ...
BACKGROUND : Blood pressure (BP) is known to increase
inevitably with age. Understanding the different ages at which
great gains could be achieved for intervention to prevent and
control BP would be of public health ...
Food composition databases (FCDBs) provide the nutritional content of foods and are
essential for developing nutrition guidance and effective intervention programs to improve nutrition
of a population. In public and ...
This dissertation proposes the development of a new quantile-based generalized logistic distribution GLDQB, by using the quantile function of the generalized logistic distribution (GLO) as the basic building block. This ...
