With the large-scale deployment of smart grids, scheme grid data aggregation has gradually enriched in recent years. Based on principle protecting user privacy, existing schemes usually choose to introduce a trusted third party (TTP) participate collaboration. However, this also increases risk privacy exposure as attacker can target TTP which provides services operators. In addition, many do no...

Abstract Wearable body weight support systems can assist individuals with mobility impairments in performing daily living activities greater ease and independence. However, existing have limitations terms of balancing their strength, compact size, interaction the ground, driving. In this paper, we present High-Strength Flexible Mechanism (HSFM) designed for support. The HSFM utilizes a coiling ...

BACKGROUND The frontal plane projection angle (FPPA) is frequently used as a measure of dynamic knee valgus during functional tasks, such as the single leg squat. Increased dynamic knee valgus is observed in people with knee pathologies including patellofemoral pain and anterior cruciate injury. As the foot is the primary interface with the support surface, foot and ankle mobility may affect th...

In many domains, users from varying backgrounds (and with varying conceptualisations of the domain) seek advice from an expert and the expert adapts their reasoning and explanation for the background of each user, using stereotypical categories of user (for example physicist or engineer). In earlier papers, the viewpoints mechanism was presented as a means of replicating this behaviour in knowl...

This work presents a synchronous collaborative graphical editor that implements a proposal of an awareness mechanism of a collaborative artifact evolution. The graphical editor allows real-time, highly interactive collaborative work, using the mask metaphor to help participants in creating new diagram versions without interrupting the interaction as also to provide awareness of the diagram vers...

The high speed network becomes an important indicator of national power in information society. The bandwidth of LAN and WAN are over the Gbps but bandwidth of subscriber access network is dozens of Mbps. Task Force team for IEEE 802.3ah has accomplished the standardization of EPON which is one of next generation subscriber access networks but it doesn’t still have the bandwidth wide enough to ...
