In the last two decades, an increasing interest has been observed in the development of effective bilateral teleoperation systems. One of the biggest challenges encountered however is the presence of time delay, which can cause instability and poor transparency to the system. Researchers have been trying to tackle this problem from different angles and various control schemes have been proposed...

In bilateral telemanipulation algorithms based on enforcing time-domain passivity, internal friction in the devices poses an additional energy drain. This can severely decrease the obtainable transparency of these algorithms when high amounts of friction are present in the slave device. Based on a model of the friction, the dissipated energy can be estimated and reclaimed inside the energy bala...

Telecooperation receives increasing importance in a globalized information and work infrastructure. Among others, teleconferencing and workflow management are technological areas being studied and developed to support telecooperation scenarios. I.e. real-time collaboration tasks are being supported by teleconferencing systems, asynchronous tasks are being supported by workflow management system...

equate public trust. In this study, we analyze Chinese grassroots organizations’ level of transparency with respect to four aspects: basic information, governance, finance, and activity transparency. We examine factors that may influence transparency and test the effects of transparency on organizations’ donation and grant income. Our findings suggest that Chinese grassroots human service organ...
