Der selektive Regressionstest ist eine aus der Softwaretechnik stammende Methodik zur (Re-)Verifikation von geänderten (Software-)Systemen innerhalb von Releasezyklen. Da es in der Praxis oft an Zeit mangelt den kompletten Verifikationsumfang erneut durchzuführen, werden unter anderem Priorisierungsverfahren angewendet diesen zu reduzieren. Diese sind jedoch ungeeignet, da sie keine systematisc...

Dancing en pointe requires the ballerina to stand on her toes, which are protected only by the pointe shoe toe box. This protection diminishes when the toe box loses its structural integrity. The objectives of this study were 1) to quantify the comparative structural static and fatigue properties of the pointe shoe toe box, and 2) to evaluate the preferred shoe characteristics as determined by ...

Zusammenfassung Geometric models are the basis of computer graphics. Due to the growing computing power and hardware support more and increasingly complex models are created. In order to efficiently store, evaluate, manipulate, and match these, it is necessary to capture and extract the essence of shape. In particular for polygonal models, a concept is developed that allows adaptation of the no...

Metal forming processes, compared with machining ones, reduce production steps and increase manufacturing speed in addition to saving raw material. In this paper, forming process of column of a steering mechanism is investigated by finite element analyses and experimental tests; and optimum die design parameters are found. Forming process parameters including die opening angle, bearing length, ...

We present a novel approach that exploits shape context to recognize emotion from monocular dance image sequences. The method makes use of contour information as well as region-based shape information. The procedure of the method is as follows. First, we compute binary silhouette images and its bounding box from dance images. Next, we extract the quantitative features that represent the quality...

In HCI (Human-Computer Interaction), the camera is often with wide angle lens and the captured image is usually distorted. The infrared image is more blurred than general image, so the contrast and the brightness is lower. In this paper, a cross shape mask is used to get the preliminary chessboard internal corners. And the adaptive threshold is put forward to remove outliers and align the corne...

The modern engineering design optimization process often replaces laboratory experiments with computer simulations, which leads to expensive black-box optimization problems. Such problems often contain candidate solutions which cause the simulation to fail, and therefore they will have no objective value assigned to them, a scenario which degrades the search effectiveness. To address this, this...
