Planning by Rewriting (PbR) is a paradigm for efficient high-quality planning that exploits declarative plan rewriting rules and efficient local search techniques to transform an easy-to-generate, but possibly suboptimal, initial plan into a high-quality plan. In addition to addressing planning efficiency and plan quality, PbR offers a new anytime planning algorithm. The plan rewriting rules ca...

The ability of a planner to reuse parts of old plans is hypothesized to be a valuable tool for improving eeciency of planning by avoiding the repetition of the same planning eeort. We test this hypothesis from an analytical and empirical point of view. A comparative worst-case complexity analysis of generation and reuse under diierent assumptions reveals that it is not possible to achieve a pro...

PURPOSE Three different techniques of low-dose-rate seed implantation for prostate cancer have been used since its use started in our hospital. The purpose of this study was to compare the results of the three different techniques. MATERIAL AND METHODS The data of 305 prostate cancer patients who underwent low-dose-rate seed implantation were retrospectively analyzed. Pre-plan technique (n = ...

We develop an optimization model based on Markovian approach to determine the optimum value of thresholds in a proposed acceptance sampling design. Consider an acceptance sampling plan where items are inspected and when the number of conforming items between successive defective items falls below a lower control threshold value, then the batch is rejected, and if it falls above a control thresh...

background: presentation of course plan were advised but presentations of  lesson plans were useful too. these items can introduce the course and lessons of each session to students.  the objective of this study was the determination of the effects of educational planning on learning of occupational diseases. methods: this study was a semi experimental study which was conducted by using the cur...

In this paper we first describe the stochastic optimal control algorithm called ((OPTCON)). The algorithm minimizes an intertemporal objective loss function subject to a nonlinear dynamic system in order to achieve optimal value of control (or instrument) variables. Second as an application, we implemented the algorithm by the statistical programming system ((GAUSS)) to determine the optimal fi...

This paper discussed the threats from farm animals to food and human security. In response to these threats, a radical reform plan was adapted by several countries and the plan includes restructure of the organization of governing agencies, implementation of a traceability system from the farm sector to end users, application of hazard control measures, as well as tightening the food import con...
