Tracking and identifying persons in videos are important building blocks in many applications. For interactive investigation of surveillance footage it is often not even necessary to uniquely identify a person. It rather suffices to find occurrences of a person indicated by the user with an exemplary image sequence. We present a system in which the search for a specific person can be initiated ...

In this paper, we consider GI/M/c queues with two classes of vacation mechanisms: Station vacation and server vacation. In the first one, all the servers take vacation simultaneously whenever the system becomes empty, and they also return to the system at the same time, i.e., station vacation is group vacation for all servers. This phenomenon occurs in practice, for example, when the system con...

A bilateral teleoperation experiment with ETS-VII was conducted on November 22, 1999. Round-trip time for communication between the NASDA ground station and ETS-VII was approximately six seconds. We constructed a bilateral teleoperator that is stable even under such a long time delay. Several experiments, such as slope tracing task and peg-in-hole task, were carried out. Experimental results sh...

Major furnace explosions have resulted in the deaths of personnel, extremely expensive repair costs and, in most cases, loss of revenue during the repair period. For a large power station boiler the total cost of a furnace explosion could easily be in the $10M to $20M range. The protection systems fitted to a modern boiler have been developed to the stage where boiler explosions are a rare occu...

We introduce a new concept of general $G$-$eta$-monotone operator generalizing the general $(H,eta)$-monotone operator cite{arvar2, arvar1}, general $H-$ monotone operator cite{xiahuang} in Banach spaces, and also generalizing $G$-$eta$-monotone operator cite{zhang}, $(A, eta)$-monotone operator cite{verma2}, $A$-monotone operator cite{verma0}, $(H, eta)$-monotone operator cite{fanghuang}...

This article presents the modeling of a disturbance on a public transportation line. The suggested model must ensure the synthesis, the evaluation and the update of information available in order to facilitate the task of the operator ensuring the monitoring of the network. In order to achieve this goal, we propose a formal modeling of the concept of disturbance. This modeling makes it possible...

An experiment to tele-operate a robot arm on a satellite from an onground control station was conducted by an astronaut who has extensive on-orbit experience in operating the Space Shuttle’s robotic arm. This experiment aimed to evaluate / compare a teleoperation system, which we developed, with the teleoperation system of the Space Shuttle Remote Manipulator System (SRMS). There was a time del...

This paper focuses on the description and the performance analysis of a new type of force feedback handle with special features. This handle has the shape of a cylindrical stick whose upper part can move with respect to the lower part. The operator seizes both parts of this handle with his hand and can move around in the surrounding space, feeling reaction forces from the upper part. This manip...

We prove that a spectral gap-filling phenomenon occurs whenever Hamiltonian operator encounters coarse index obstruction upon compression to domain with boundary. Furthermore, the spectra contribute quantised current channels, which follow and are localised at possibly complicated This is shown be insensitive deformations of boundary, so generic for magnetic Laplacians modelling quantum Hall sy...
