WEA is our implementation of a new architectural model for virtual memory access, the WorkSpace. It relies on a generalisation of client / server model and enables to build new distributed applications. The workspace supplies uniform access to a distributed persistent object store. This paper describes several ways of building multi-workspace architecture, and an implementation of this architec...

UNLABELLED The article examines which subjectively evaluated indoor environmental parameters and building features mostly affect occupants' satisfaction in mainly US office buildings. The study analyzed data from a web-based survey administered to 52,980 occupants in 351 office buildings over 10 years by the Center for the Built Environment. The survey uses 7-point ordered scale questions perta...

Isometric force generation and kinematic reaching in the upper extremity has been found to be represented by a limited number of muscle synergies, even across task-specific variations. However, extent generalizability synergies between these two motor tasks within arm workspace remains unknown. In this study, we recorded electromyographic (EMG) signals from 13 different arm, shoulder, back musc...

We present a perception system, called Artisan, that semi-automatically builds 3-D models of a robot’s workspace. Range images are acquired with a scanning laser rangefinder and then processed, based on a systematic sensor characterization, to remove noise and artifacts. Complex 3-D objects represented as surface meshes are subsequently recognized in the range images and inserted into a virtual...

this paper presents the kinematic analysis and the development of a 4-degree-of-freedom serial-parallel mechanism for large commercial vehicle driving simulators. the degrees of freedom are selected according to the target maneuvers and the structure of human motion perception organs. several kinematic properties of parallel part of the mechanism under study are investigated, including the inve...

We propose a novel low-cost method for quantitative assessment of upper extremity workspace envelope using Microsoft Kinect camera. In clinical environment there are currently no practical and cost-effective methods available to provide arm-function evaluation in three-dimensional space. In this paper we examine the accuracy of the proposed technique for workspace estimation using Kinect in com...

One of the weak aspects of the parallel robots is ratio between the workspace and the dimension of the mechanical structure, if compared with the serial one. Hence the shape of the workspace of a parallel manipulator is one of the most important aspects to reflect its working capacity. This paper introduces two innovative methods to analyze the workspace of some family of parallel robots, with ...
