The kinematical accuracy of robot is very important. It is induced by the rigidity of each mechanism of the robot. The paper presents a numerical method to evaluate the rigidity of worm-gearing teeth. The software, including setting-up and graphic display, could be adopted of any kind of cylindrical worm-gear drive or for spur gear drives and bevel gear drives, mechanisms which are in the robot...

Cockpit moving-maps have provided heightened situation awareness to Navy fighter pilots for over ten years. The Navy now plans to install a moving-map into its multifunction MH-60S helicopter, which will perform sea-based missions such as combat search and rescue and mine countermeasures. The authors surveyed 49 Navy helicopter aircrew for their preferences with respect to four map types and si...

In this paper, we propose a new concept of visual/haptic interfaces called WYSIWYF display. The proposed concept provides correct visual/haptic registration using a visionbased object tracking technique and a video keying technique so that what the user can see via a visual interface is consistent with what he/she can feel through a haptic interface. Using Chroma Keying, a live video image of t...

Noninvasive measurements of regional cerebral blood flow (rCBF), using the Xe-133 clearance technique and a two-compartment open model for data analysis, may produce false numerical results when distinction between compartments is poor. For rapid detection of error conditions of that kind, we propose a three-dimensional graphic display of the quality of fit to the original clearance curve, base...

A simple, standardised procedure was used for processing data from External Quality Assessment Schemes and for producing performance charts. A graphic presentation of cumulative performance is generated for each test, using an integrated software package to display results in a standardised format. This permits interpretation of satisfactory and poor performances and facilitates identification ...

Xa-lan is a computer program written in Common-LISP to generate music scores with a high level of notational/symbolic expressivity. Generation is driven by audio-analysis of melodic profiles. Once a melodic contour is input to the software, graphic transformations of the original profile stochastically control the different notational elements of the score. The Xa-lan routines display their fin...

Spatial haptic displays, such as electrostatic vibration (electrovibration) based friction displays, augment flat panels and surfaces with spatially arranged tactile content. Such devices can be useful for the visually impaired to translate visual images to tactile ones on demand. In this paper, we explore a tactile palette that consisted of a set of six perceptually distinct tactile stimuli co...

For the issue of the lack in plotting analysis method in the research of DEA, this paper introduces a new graphic method—Co-Plot. It can demonstrate DMUs and variables visually in two-dimensional space, and enable the analysis of them at the same time. By applying the ratio relationship among variables, Co-Plot can be combined with DEA in a way to display the results of DEA easily and intuitive...

We propose here an approach of the morphophonological treatment of borrowed lexical items in the general French lexicon, through the mecanims of the functionning of the TTS Toph. We will show how the methodology we adopted in this TTS allows us to distinguish two levels of processing, adapted to the nature of the items. After the display of the typology of phonetic transfers we will focus on th...
