This paper presents a method based on neural networks to detect broken rotor bars and end rings in squirrel cage induction motors. In the first part, detection methods are reviewed and traditional methods of fault detection as well as dynamic&#10model of induction motors are introduced using the winding function method. In this method, all stator and rotor bars are considered independently in o...

II. Aetna considers computer-aided detection for chest radiographs experimental and investigational for screening or diagnosis of lung cancer and for all other indications. There is presently inadequate evidence in the medical literature that population-based mass lung cancer screening with computer-aided detection for chest radiographs will contribute substantially to the detection of smaller ...

Sketches, with their flexibility and suggestiveness, are in many ways ideal for expressing emerging design concepts. This can be seen from the fact that the process of representing early designs by free-hand drawings was used as far back as in the early 15th century [1]. On the other hand, CAD systems have become widely accepted as an essential design tool in recent years, not least because the...

Modeling of products (objects) form a critical task in design and manufacturing. CAD–CAM techniques based on solid/geometric modeling have been developed for this purpose. Primarily, these methods capture the shape of the object. However, recent developments in diverse fields demand modeling schemes, which extend beyond the shape to include other relevant attributes of the object. In this paper...

This paper describes a new approach to solve the problem of intersecting features extraction. Feature extraction is important from several standpoints—automated process planning, NC machining, automated assembly and virtual prototyping. Feature extraction reported in the literature indicates limited success mostly in extracting a partial list of non-intersecting features. There has not been muc...

Loose fitting garments can accommodate a greater number of different bodyshapes but close fitting garments cannot. The assumption is that stretch garments will automatically stretch in the right places to give an acceptable fit and provide comfort as well as ease of movement. But this is a fundamental misunderstanding of stretch fabric characteristics and garment pattern geometry. To date the g...

Many computer-aided diagnosis (CAD) methods, including 2D and 3D approaches, have been proposed for solitary pulmonary nodules (SPNs). However, the detection and diagnosis of SPNs remain challenging in many clinical circumstances. One goal of this work is to investigate the relative diagnostic accuracy of 2D and 3D methods. An additional goal is to develop a two-stage approach that combines the...

The basis of Knowledge Intensive CAD (KIC) is that “intensive life-cycle knowledge regarding products and design processes must be incorporated in the center of the CAD architecture.” We would like to extend this concept slightly by concentrating on the presentation of designs and design information to the designer. In this we argue that knowledge about some aspects of the design process must b...

Who could have imagined a decade ago what an enormous range of possibilities CAD/CAM systems would offer to the dental laboratory of today? The development of equipment and software, and also the materials which can be processed, has advanced at an unexpected rate in recent years. Anyone who as a manufacturer does not “go along with it”, or even worse lets the competition overtake him, has no c...

Multidisciplinary optimization systems rely increasingly on parametric CAD engines to supply the geometries required by their analysis components. Such parametric geometry models usually result from an uneasy compromise between high flexibility, that is, the ability to morph into a wide variety of topologies and shapes, and robustness, the ability to produce feasible, sensible topologies and sh...
