Object-based attention would result if target appearing at an invalid location on the same object is detected more quickly than target on an equidistant location on different object (e.g., Egly, Driver, & Rafal, 1994). Three experiments examined the form of object-based attention typical object-based attention paradigms elicit (object-based benefits from the spread of attention across objects o...

VAR support should be supplied as close to the load as possible to minimize transmission losses. For voltage control and for improvement of total power factor in a distribution system the circuit- breaker switched capacitor banks can be used. The problems with this solution are the voltage steps caused by the large sizes of the capacitor banks as well as the transients caused on insertion. Thyr...

We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...

Several heterogeneous positioning systems are more and more widespread among client wireless terminals, thus leveraging the market relevance of Location Based Services (LBSs). Positioning techniques are very differentiated, e.g., in terms of precision, accuracy, and battery/bandwidth consumption, and several of them are simultaneously available at clients. That motivates novel middleware soluti...

Previous studies have shown conflicting data as to whether it is possible to sequentially shift spatial attention among visual working memory (VWM) representations. The present study investigated this issue by asynchronously presenting attentional cues during the retention interval of a change detection task. In particular, we focused on two types of sequential attention shifts: (1) orienting a...
