SQL:2007, die sich momentan noch in Entwicklung befindende nächste Version der SQLNorm, erweitert den aus SQL:2003 bekannten SQL-Datentyp ” XML“. Als Instanzen dieses Datentyps sind nun auch komplette XQuery-Sequenzen erlaubt. Infolgedessen können SQL:2007-Anfrageergebnisse vollständige XQuery-Sequenzen als Attributwerte besitzen. Damit stellt sich die Frage, wie XQuery-Sequenzen, die im Anfrag...

Using transaction data from the Jakarta Stock Exchange, I nd three pieces of evidence which indicate that domestic investors have an information advantage over foreign investors. First, foreign investors systematically buy at higher and sell at lower intra-day prices than domestic investors. Second, foreign investors tend to sell prior to large positive returns. Finally, the permanent impact of...

Vanderhorstia mertensi Klausewitz, 1974, is a recently acknowledged alien fish in the Mediterranean Sea, hitherto observed only from Fethiye Bay, Turkey. To explore its distribution, trawl bycatch from eastern Antalya and Iskenderun was examined and an underwater survey was performed off Kas (western Antalya). An established population was found off Güvercin Island, Kas, and six specimens were ...

Many stocks of Atlantic cod (Gadus morhua) on both sides of the North Atlantic are currently at much reduced levels of biomass, but this situation is not in all instances the result of long, continuous decline. Most Northwest Atlantic stocks declined to low levels during the 1970s, but increased during the 1980s before declining even more severely during the late 1980s and early 1990s. Several ...

This paper considers view-dependent rendering method for 3D models represented as binary volumetric octree (BVO) together with reference images and corresponding cameras locations. This representation was proposed and accepted to MPEG-4 AFX (Animated Framework eXtension) as Octree Image Node in the Depth-Image Based Representations (DIBR) group. Originally DIBR-objects were assumed to be diffus...

Time synchronization is critical to modern electrical power systems. Based on the lessons learned from the postdisturbance analysis of the August 14, 2003, northeast blackout, NERC (North American Electric Reliability Corporation) recommendations place a high priority on implementing time synchronization in data-recording devices. This eliminates or reduces the effort involved in comparing even...

Simultaneous genetic evaluations for bulls and cows obtained by mixed model procedures with an animal model incorporating all numerator relationships for artificially sired Holstein cows in northeastern United States were compared with separate (Northeast) mixed model evaluations of cows and sires for predicting genetic evaluations of progeny from dam, sire, and maternal grandsire evaluations. ...

One of the most promising applications of the family of electronic devices called Flexible AC Transmission System (FACTS) devices is to better regulate power flow in transmission grids. In particular, the Unified Power Flow Controller (UPFC) is the best choice for complete control of power flow control. By selecting proper installation locations and control techniques, UPFCs may be able to prev...
