This paper first provides a general introduction to Computer Aided Process Planning (CAPP). In second section, a brief review of Computational Intelligence (CI) applications in machining process planning and related methods and problems will be presented. The overall applications can be classified as knowledge representation, features extraction, part classification for group technology, machin...

In this paper we propose a variational approach to a path planning problem in 2 dimensions using a level set framework. After defining an energy integral over the path, we use gradient flow on the defined energy and evolve the entire path until a locally optimal steady state is reached. Unlike typical level set implementations where the interface being tracked is a codimension-1 set, we allow f...

This paper describes an algorithm for minimizing the non-productive time or ‘airtime’ for a tool by optimally connecting the toolpaths for that tool. This problem is formulated as a generalized traveling salesman problem with precedence constraints and is solved using a heuristic method. The performance of the heuristic algorithm and the amount of improvement obtained for different problem size...

In video games and robotics, one often discretizes a continuous 2D environment into regular grid with blocked unblocked cells then finds shortest paths for the agents on resulting graph. Shortest paths, of course, are not necessarily true in environment. this article, we therefore study how much longer path can be than corresponding all grids that tessellate environments. We 5 different vertex ...

aim: level of physical activity as key determinant of healthy lifestyle is less than what isrequired in individuals particularly women. applying theories of behavioral change aboutcomplex behaviors such as physical activity leads to identify effective factors and their relations.the aim of this study was to determine predictors of exercise behavior based on developedtheory of planned behavior w...

one of the most important factors in the development of societies, consider to traning. identification and training needs analysis, is a prerequisite for a successful educational system and determine the training needs is considered the first step of educational planning. the purpose of this study was to investigate educational needs of engineers, rice supervisors engineering agricultural engin...

Path planning for an autonomous vehicle can occur at two different times. First, path planning might occur at mission specification time when the vehicle’s initial path is determined and used to specify other mission factors. This task makes use of some model of the environment in planning a path that will avoid obstacles and hazardous areas. A second type of path planning might occur while the...
