The aim of our study is to analyze the impact of insertion holes in the middle of obstacles on the flow around a surface-mounted cube, In order to do this; we studied four configurations of obstacles in a channel with a Reynods number based on obstacle height ReH = 40000. The hexahedral structured meshes were used to solve the fluid dynamics equations .The finite volume method are employed to s...

An analytical technique is proposed for estimation of the radiation pattern of inverted-F antenna (IFA) which is mounted on the side wall of a long cylinder. The method can be applied to describe the IFA radiation in a lot of practical cases. It is indicated that this radiation pattern is a combination of radiation patterns of a horizontal and a vertical small radiator, near the cylinder with a...

We explain how to adapt a construction of M. Sageev’s to construct a proper action on a CAT(0) cube complex starting from a proper action on a wall space.

Three-dimensional kinematics of body targets are frequently tracked during vehicle impact tests using instrumented cubes. While the components of linear acceleration and angular velocity are recorded in a cube local coordinate system, transformation to a global coordinate system is required to reconstruct the whole body motions. This paper presents a methodology for local-to-global kinematic tr...

In this paper, we propose several results about trajec-tory generation by visual servoing. The approach consists in deening a speciic task function which allows us to take into account the time varying aspect of the reference feature and we synthesize a control law in the sensor space. This control law ensures the trajectory control in the image space and reduces the tracking error. Under speci...

Abstract

The classic obstacles in the digital augmentation of everyday objects and appliances are usually situated around batteries, communication, size, and weight. Wired communication is often not possible, changing or charging batteries is generally considered a nuisance, and augmenting an appliance is usually not worth it if it means increasing its size or weight. For the subclass of devices an obje...

Since operating room departments are among the costliest resources at a hospital, much attention is devoted to maximize their utilization. Operating room activities are however notoriously hard to plan in advance. This has to do with the unpredictable, problem-solving nature of the work and that the work is carried out by a multidisciplinary team of health personnel, members of which also have ...
