Up to 75 % of the overall work piece error can be caused by thermo-elastic behavior machine tool. Therefore, correction methods based on machine-integrated sensors were intensively researched during last years, in order determine Tool Center Point (TCP) parallel process. One these includes integral deformation sensor (IDS), which detects along length a structural component machine. The TCP is m...

Applications of vision-based remotely operated robotic systems range from planetary exploration to hazardous waste remediation. For space applications, where communication time lags are large, the target selection and robot positioning tasks may be performed sequentially, differing from conventional telerobotic maneuvers. For these point-and-move systems, the desired target must be defined in t...

Wireless indoor positioning has been a popular research topic for years because it provides the basis for a broad domain of location-based applications. Especially the usage of WLAN (Wireless Local Area Network) technology is widespread to build an indoor positioning system due to the reuse of existing and almost ubiquitous WLAN infrastructure worldwide lowering the costs. However, these WLAN s...

Position information is often one of the key requirements for a wireless sensor network (WSN) to function as intended. Due to drawbacks in using GPS or having to manually setting sensor positions, extracting the position information by means of the network itself has been extensively studied in the literature. In this approach, it is commonly assumed that there are a few sensor nodes with known...

in this paper, a new method based on branch placement for the optimal positioning of phasor measurement units (pmus) in power systems is proposed. in this method, the pmus are in type of single-channel and are installed at the beginning of the branches. therefore, they are able to measure the bus voltages. also, the installation of the pmus on the branches increases the security of observabilit...
