In this paper, we study the reactive scheduling problems in a stochastic manufacturing environment. Speci®cally, we test the several scheduling policies under machine breakdowns in a classical job shop system. In addition, we measure the e€ect of system size and type of work allocation (uniform and bottleneck) on the system performance. The performance of the system is measured for the mean tar...

This paper presents two examples that use sensors implemented in Java to build distributed applications. At rst, the design of sensors based on the reactive system model and the implementation of these sensors in Java are outlined. After a brief description of the performance analysis, the two application examples that use these sensors are presented. The two examples show the advantage of usin...

We present a new approach to reinforcement learning in which the policies considered by the learning process are constrained by hierarchies of partially specified machines. This allows for the use of prior knowledge to reduce the search space and provides a framework in which knowledge can be transferred across problems and in which component solutions can be recombined to solve larger and more...

Recently, CEBP published a new editorial policy for association studies of genetic variants and disease (1). The policy gives high priority to studies that meet several criteria. The studies must (a) evaluate a variant in light of its possible interaction with other genes in a pathway and with exogenous exposures: (b) consider the biological plausibility of the reported association(s), and the ...

Experimental biology is a dynamic and rapidly evolving area of research. Consequently, new techniques and concepts are constantly appearing. As this occurs, The Journal of Experimental Biology (JEB) also adapts to keep pace as we see manuscript submissions increasingly using new approaches to better understand the mechanisms that underlie organismal function and diversity. In recent years, two ...

publicpolicies are the functions of the political systems for the national sovereignty. governments govern national wills under public policies. if the legislative version of these public policies be provided upon the scientific and political considerations it still remains useless unless it could pass the implementation stage successfully. the implementation of the public policies is the main ...

abstract background: at present study, acid modified banana leaf ash was used as an adsorbent for the successful removal of reactive black 5 (rb5) dye from aqueous environments. materials and methods: the effect of various operating parameters such as ph of solution, dye concentration, contact time, adsorbent dosage, and the temperature was investigated. results: maximum adsorption capacity of ...

results seminal plasma tac level in normospermic men was significantly higher than asthenoteratospermic men (p < 0.001) and oligasthenoteratospermic men (p < 0.001) and had posetive correlation with sperm count, motility and morphology. in contrast mda levels in normospermic men were significantly lower than in asthenoteratospermic men (p = 0.049) and oligoasthenoteratospermic men (p = 0.001) a...
