In this paper three different formulations of a Bernoulli type free boundary problem are discussed. By analyzing the shape Hessian in case of matching data it is distinguished between well-posed and ill-posed formulations. A nonlinear Ritz-Galerkin method is applied for discretizing the shape optimization problem. In case of well-posedness existence and convergence of the approximate shapes is ...

This article proposes a deformable water-mobile robot that can be used for rescue work. The body adopts an open-motion chain structure with two degrees of freedom, including drive modules and one main control module. three are connected through deformation joints, each module is equipped underwater thruster. obtain triangle, linear shape, curved U-shape have types motion: shape motion, U-shaped...

Nailfold capillaroscopy is a reliable way to detect and analyze microvascular abnormalities. It safe, simple, noninvasive, inexpensive. Among all the capillaroscopic abnormalities, nailfold microhemorrhages are closely associated with early vascular damages might be present in numerous diseases such as glaucoma, diabetes mellitus, systemic sclerosis. Segmentation of provides valuable pathologic...

A suitable initial point for understanding multiphase flows is a phenomenological description of the mechanism geometric distributions or flow patterns that are observed. The challenge however prediction combination operating conditions and characteristics phases as well points transition from one pattern to other. Different occur in different pipeline configurations which U-shape risers part. ...

This paper presents a novel technique for Shape from Light Field (SfLF), that utilizes deep learning strategies. Our model is based on a fully convolutional network, that involves two symmetric parts, an encoding and a decoding part, leading to a u-shaped network architecture. By leveraging a recently proposed Light Field (LF) dataset, we are able to effectively train our model using supervised...

There is a large amount of cross-sectional evidence for a midlife low in the life cycle of human happiness and well-being (a 'U shape'). Yet no genuinely longitudinal inquiry has uncovered evidence for a U-shaped pattern. Thus, some researchers believe the U is a statistical artefact. We re-examine this fundamental cross-disciplinary question. We suggest a new test. Drawing on four data sets, a...

Although the relationship between stress intensity and memory function is generally believed to follow an inverted-U-shaped curve, strikingly this phenomenon has not been demonstrated under the same experimental conditions. We investigated this phenomenon for rats' performance in a hippocampus-dependent learning task, the radial arm water maze (RAWM). Variations in stress intensity were induced...
