Intelligent system for extraction of product data from CADD models
نویسندگان
چکیده
This paper reports a system for automatic extraction of geometric and non-geometric part information from `engineering drawings' created using computer-aided design and drafting (CADD) tools. A heuristic search is employed to interpret the characteristic attributes of dimension sets that denote linear, diametrical, radial and angular dimensions. Textual callouts are processed using natural language processing (NLP) techniques to interpret information related to part/feature function and related processes. The part information so recognized is represented using object oriented paradigm (OOP) suitable for linking to the downline CAD/CAM activities of the product cycle. The system, thus provides an effective alternative for design automation using CADD models.

Design and Implementation of a Fuzzy Intelligent System for Predicting Mortality in Trauma Patients in the Intensive Care Unit
Introduction: The intensive care unit is one of the most costly parts of the national health sector. These costs are largely attributable to the length of stay in the intensive care unit. For this reason, there are significant benefits in predicting patients' length of stay and the percentage of deaths in intensive care units. Therefore, in this study, a fuzzy logic based intelligent system was...
