This paper describes a method to achieve a vision-cued swaying task in unknown environments utilizing adaptive visual servoing. The proposed method has a hybrid structure consisting of a controller to keep the distances between feet constant (a stance servo-ing controller), and an adaptive visual servoing controller. Making use of the method, the motion of(More)
In the ubiquitous computing environment, we believe that P2P-based context-aware application utilizing sensing data is important. However, since sensors are not placed under the control of one specific entity, it is difficult to retrieve appropriate information from the distributed sensors. In addition , when the same queries are sent by different users,(More)
In this paper, we propose an overlay network called HDOV, a hierarchical extension of Delaunay overlay network for data collection with multiple spatial resolutions. By using HDOV, spatial data with at least specified spatial resolution can be collected reducing the redundant messages for data collection from wide area peer-to-peer network. The proposal in(More)
AIM The objective of this study was to analyze the oral health among Japanese adults, with and without diabetes mellitus. METHODOLOGY The subjects were 518 community residents aged 20 to 91 years in Japan, who participated in the "Akita health and nutrition survey" and the "Akita dental disease survey", conducted in 2006. The surveys comprised a(More)
In this paper, we propose a P2P user search method based on movement records that can be automatically obtained by location detection devices. We assume movement records are treated as a sequence of pairs of spot-ID and time and they are stored in a peer for each user. In our proposal, a Bloom Filter is applied to each spotID and time to combine all(More)
Mammalian target of rapamycin (mTOR) inhibitors have anti-tumor effects against renal cell carcinoma, pancreatic neuroendocrine cancer and breast cancer. In this study, we analyzed the antitumor effects of mTOR inhibitors in small cell lung cancer (SCLC) cells and sought to clarify the mechanism of resistance to mTOR inhibitors. We analyzed the antitumor(More)
—In the location dependent information services, not only estimation of the coordinates of a user (coordinate estimation), but also existence check of a user whether he/she exists in a certain area or not (area estimation) are required. However, no existing research on location estimation method using wireless communication treats both coordinate estimation(More)
