Of course, setting up a summarization model that ensures smooth integration with human thinking is a relatively long process. Fig. 1 shows where the researchers are located in such a research strategy: An empirical model describing the intellectual strategies of human expert summarizers has been elaborated and published (most comprehensively in Endres-Niggemeyer 1998). The empirical model has b...

Travel fatigue is associated with long haul flights, and jet lag is experienced when flights entail transmeridian travel. Symptoms are linked with disturbance of the body’s circadian rhythms. Exercise performance may be affected until the body clock is adjusted to the new time zone. Methods of speeding up the adjustment include pharmacological and behavioral methods. Emphasis is placed on behav...

The unprecedented growth in industrial motor drives over the past decade resulted from the process improvements demanded by the automation industry. With the increased speed of modern micro-controllers and digital signal processors and the reduced Insulated Gate Bipolar Transistor (IGBT) drive package size, coupled with the low maintenance of ac motors, multiple machine configurability has been...

In this paper, we address the problem of scrambling regions of interest in a video sequence. We target applications such as video surveillance preserving privacy, anonymous video communications, or TV news safeguarding the anonymity of a source. We propose an efficient solution based on transform-domain scrambling. More specifically, the sign of selected transform coefficients is flipped during...

Prior studies have shown that the IT innovation capability, a company's ability to innovate systematically with IT, is not easily replicated (persistent), and the persistence tends to be more pronounced during periods when economy-wide IT budgets are declining (hard IT budgets), such the post-Y2K period. Building on resource based view we argue that companies that systematically innovate with I...

This publication proposes a strategy to enhance the compression performance of Motion-JPEG2000 by the reduction of interframe redundancies. This is achieved by a new frame structure allowing to remove redundancies and to reconstruct the original stream without loss. The introduced advancement is able to increase the compression e ciency and keeps other bene cial property of the traditional code...

Y2K presented a formidable (albeit welldefined) challenge: find the date problems and fix them (see our “Congratulations” in the accompanying sidebar). Post-Y2K presents a more formidable challenge: a...

Image transmission with JPEG2000 can be speeded up by using regions of interest (RoIs). By such a mechanism, parts of an image not belonging to RoIs can be transmitted later or encoded at a lower bit rate. This paper describes a flexible dynamic RoI-scheme which supports the definition and handling of arbitrarily-shaped RoIs in JPEG2000. The scheme supports the dynamic definition and prioritiza...

Mainstream Information Technology professionals have misunderstood the Pick environment for many years. The Pick environment has been conceived, designed and built with business solutions as its key driver. At its heyday there were over 3,000 business applications available across a very wide range of hardware platforms supporting from 1 to thousands of real time users. The tentative economic r...

With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the speci®c area of still image encoding, a new standard is currently being developed, the JPEG2000. It is not only intended to provide rate-distortion and subjective image quality performance superior to existing standards, but also to provide funct...
