An OFDM Timing Synchronization ASIC

In this paper an OFDM timing synchronization ASIC is presented. The proposed synchronization unit can be used in any OFDM system. The algorithm is based on the correlation introduced by the cyclic prefix, which is exploited in the time domain where the time offset is estimated. Although the algorithm is too complex to be implemented on today's most powerful standard DSP, a hardware architecture th

Professional groupings and customized deliveries in industrial organizations

This paper discusses effects of an increased reliance on professionals in industrial organizations and whether educational background or belongingness to professional groups may be linked to ways of working when supplying highly customized deliveries, and consequently the innovativeness of the organization. The study upon which this paper is based attaches to theories related to traditional indust

Abstract in German Die Untersuchungen von mechanisch-biologisch vorbehandelten Restabfällen haben gezeigt, dass im Rahmen einer 9 wöchigen Rotte im Containersystem die organikreiche Fraktion stabilisiert - und das Emissionspotentials um ca. 95 % verringert werden kann. Darüber hinaus erfolgt durch biologische Abbau- und Umbauprozesse der Aufbau einer Huminstoffmatrix, die einerseits im Feststoff aThe research study on mechanical-biological pre-treated wastes has shown, that the emission potential can be reduced of appr. 95% while the aerobic treatment in a con-tainer system of a large-scale treatment plant. Humification processes can be detected, Humic substances are build up while the aerobic processes and can be analyzed in the organic matter and in the eluate. The humic substances are p

The potential of a parser in a language teaching program

This paper reports on results from studying what a parser can do when combined with Hypercard on a Macintosh computer to form a pedagogical tool for language teaching purposes. The system was applied to Japanese, but the exercises could easily be altered to suit other languages as well. There are exercises for learning vocabulary, hiragana (see Writing system below) and grammar. The focus is on sy
