Zusammenfassung Die komplexen Strukturen der vorhandenen Krankenhaus-Patient*innen-Schnittstelle sowie zugehörige IT-Systeme, eingesetzte Speichermedien und die dezentralen Kontaktkanäle begründen häufig hohe administrative Aufwände im Gesundheitswesen. Diese Schnittstelle für Patient*innen sind meist unabhängig voneinander organisiert auf Daten- bzw. Systemebene nicht verbunden – sie unterlieg...

G-induced loss of consciousness (G-LOC) has emerged as an important operational problem of high-performance aircraft. Since it appears that G-LOC will continue to be a problem, a requirement exists to detect its occurrence in pilots so that the aircraft may be placed on autopilot. One excellent method of detecting G-LOC physiologically, one would assume, would be based on the oxidative status o...

The purpose of this study was to identify characteristics of everyday listening situations that influence user preferences for omnidirectional versus directional hearing aid microphones. Eleven experienced hearing aid users were fitted with digital hearing aids featuring switchable omnidirectional (OMNI) and adaptive-directional (DIR) modes (programs). For 6 weeks, their task was to identify an...

Autosophy, an emerging new science, explains "Self-assembling Structures", such crystals or living trees, in mathematical terms. This research provides a new mathematical theory of "Learning" and a new "Information Theory" which permits the growing of self-assembling data network in a computer memory similar to the growing of uData Crystals" or "Data Trees" without data processing or programmin...

Broadcast has been widely used in mobile ad hoc networks (MANETs) as a communication means to disseminate information to all reachable nodes. However, the conventional broadcast scheme that broadcast packets omni directionally suffers from several drawbacks: excessive amount of redundant traffic, exaggerated interference/contention among neighboring nodes, and limited coverage (as a result of c...
