A probabilistic expert system provides a graphical representation of a joint probability distribution which enables local computations of probabilities. Dawid (1992) provided a ``ow-propagation' algorithm for nding the most probable connguration of the joint distribution in such a system. This paper analyses that algorithm in detail, and shows how it can be combined with a clever partitioning s...

We address the following problem: Given a simple polygon $P$ with $n$ vertices and two points $s$ and $t$ inside it, find a minimum link path between them such that a given target point $q$ is visible from at least one point on the path. The method is based on partitioning a portion of $P$ into a number of faces of equal link distance from a source point. This partitioning is essentially a shor...

A probabilistic expert system provides a graphical representation of a joint probability distribution which enables local computations of probabilities. Dawid (1992) provided a ‘flow-propagation’ algorithm for finding the most probable configuration of the joint distribution in such a system. This paper analyses that algorithm in detail, and shows how it can be combined with a clever partitioni...

range management needs information on distribution of livestock. the better the distribution of the livestock, the more uniform the use of the rangeland. this study was conducted to record the path of the herd steering by the shepherd. a gps was attached to a three year old ewe which was moving with the flock. the path of flock movement was recorded for three years on a monthly basis during the...

Unlike centralized databases, watermarking of distributed databases faces serious challenges for various reasons, e.g. (i) Distribution of data (ii) Existence of replication (iii) Preservation of watermarks while partitioning and distributing databases, etc. In this paper, we propose a novel watermarking technique for distributed relational databases considering a generic scenario that supports...

This paper presents a pattern language for the perception, design and implementation of distributed application partitioning. The pattern language describes a stepwise development which offers the following qualities: expressiveness and support of a wide range of user models; smooth transformation of an object-oriented model onto a client-server model; selective transparency; customization; inc...

evaluation of any irrigation system consists of analyzing the measurable performance of the system in real conditions as well as during the normal operation of the farm. irrigation evaluation is a management tool that allows the system manager to make the best use of what is available. unfortunately, in most regions of iran, after the implementation of irrigation systems their performance is no...
