This study used archived remote sensing images to depict the history of changes in soil salinity in the Hetao Irrigation District in Inner Mongolia, China, with the purpose of linking these changes with land and water management practices and to draw lessons for salinity control. Most data came from LANDSAT satellite images taken in 1973, 1977, 1988, 1991, 1996, 2001, and 2006. In these years s...

Distributed organizations increasingly rely on new video-supported communication technologies that may be subject to transmission delays. These delays systematically misalign the feedback one side receives from the other. Through microanalysis of video data from a video-supported' meeting in a geographically distributed company, we examine the impact of delay in such communication systems We sp...

A remotely controlled microgripper has been developed as an end-eeector for a six-degree-of-freedom force-reeecting motion-scaling system. The microgrip-per is small and lightweight, and features relatively high force and stroke compared to other designs. Furthermore , force sensing enables the accurate measurement and control of tool-tissue forces, and the em-ulation of diierent mechanical dev...

This paper examines the role of visual information in a remote help-giving situation involving the collaborative physical task of designing a prototype remote control. We analyze a set of video recordings captured within an experimental setting. Our analysis shows that using gestures and relevant artefacts and by projecting activities on the camera, participants were able to discuss several des...
