The burst allocation algorithm is responsible about calculating the appropriate dimensions and location of each user’s data to construct the bursts in the downlink subframe in term of the number of slots for each user. Burst allocation is one of the performance parameter which influences the mobile WiMAX systems, due to resource wastage in the form of unused and unallocated slots per frame whic...
An outstanding problem for evolutionary biology is the maintenance of anisogamous sex in the face of the ostensible twofold reproductive advantage accruing to parthenogenetic females that do not produce male offspring (Williams, 1975; Maynard Smith, 1978; Bell, 1982). Conventional solutions are sought in terms of cryptic advantages to sex involving variable environments, genetic load, and DNA d...
Multiculturalism and its associated plurality of value systems is rapidly becoming the norm in modern medical practice. Given this increasing diversity, greater emphasis upon cultural and ethical competence in physician training is necessary in order to provide culturally sensitive and ethically sound care. Religious values shape ethical codes and are expressed in the cultural norms of subcommu...
One of the influential tools concerning the rangeland and vegetation sciences isthe technology of remote sensing and satellite data. Satellite data have played essentialroles in preparing the needed information for studying the vegetation. Vegetation has beenwidely recognized as one of the best indicators for determining the land conditions. Usingvegetation indices is one of the techniques of r...
The turbidity of lakes is generally considered to be a smooth function of their nutrient status. However, recent results suggest that over a range of nutrient concentrations, shallow l&es can have two alternative equilibria: a clear state dominated by nquatic vegetation, and a turbid state characterized by high algal biomass. This bi-stability has important implications for the possibilities of...
Gully erosion is one of the most significant erosion types. This type of erosion is one of the most important sources of sediment in different regions of the world. Gullies often have different dimensions and complex characteristics and these characteristics may affect the distribution of vegetation. Topographic characteristics of gullies provide complex ecosystem for vegetation establishment. ...
Determination of vegetation and soil interaction is necessary for sustainable use of rangeland ecosystem. Soil-vegetation interrelationships in galbanum (Ferula gummosa) habitats of Ataeeye and Shoorrud- Khorasan-e- Razavi Province, Iran were studied using multivariate analysis. The stratified- random system of sampling was employed to randomly collect vegetation and soil samples from 46 quadra...
IoT has been a great use in the modern world; the importance and usage of IoT’s are increasing day by day. There is lots of research going into IoT based power management systems. The increase in power requirement has pushed the researchers and industrialist to design low power systems. The wastage of energy is a very serious concern; this paper proposes a novel method to reduce the wastage of ...
Student w astage during basic nursing programmes has been estimated at between 20% and 47% per annum over the last 10 years (Kotze, 1987; SANA. 1983). The training of every student costs the state approximately R13 500 per annum according to an investigation done by the SA Nursing Association in 1987. The economic loss due to the student wastage is therefore significant. At the same time studen...
