In recent years, designing “energy-aware manufacturing scheduling and control systems” has become more and more complex due to the increasing volatility and unpredictability of energy availability, supply and cost, and thus requires the integration of highly reactive behavior in control laws. The aim of this paper is to propose a Potential Fields-based flexible manufacturing control system that...

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...

Agricultural waste management is one of the important issues that agricultural producers should consider to increase their income and environmental protection. Therefore, the investigation of factors that reduce the rate of agricultural production wastage as well as citrus production wastage is of utmost consequence in order to manage wastes, reduce environmental degradation and ecosystem destr...

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...

Background: Excessive ordering of blood components imposes heavy costs to blood transfusion centers and increases the amount of blood product wastage due to lack of their use. In recent years, attempts have been made against unnecessary blood and blood product requests in our country. We aimed to investigate the frequency of blood and blood product wasting in healthcare centers of Yazd city in ...

Results: The overall wastage factor for BCG vaccine was 1.83, for OPV was 1.33, for DPT was 1.19, for Hepatitis B vaccine was 1.26 and for Measles vaccine was 1.39. The WF was highest for sessions held at ICDS for BCG vaccination (3.38) followed by sessions held at mobile sites for BCG vaccination (2.50). The WF was lowest for sessions held at UHC for DPT vaccination (1.11) followed by sessions...
