Das V-Modell XT hat das etablierte V-Modell 97 als verbindlicher Standard zur Durchführung von IT-Projekten der öffentlichen Hand abgelöst. In diesem Beitrag ziehen wir ein erstes Mal Bilanz über die aktuell laufenden Pilotprojekte. Wir geben einen kurzen Überblick über die Charakteristiken der einzelnen Projekte und deren Umfang. Wir skizzieren die Anpassbarkeit des V-Modell XT anhand der Pilo...

Dienstleistungen für das überbetriebliche Gesundheitsmanagement zu planen, bedarf einer strukturierten Vorgehensweise. Dienstleistern fehlten hierfür bislang geeignete Werkzeuge, die die Auswahl und Bewertung kundenorientierter, sektorspezifischer Dienstleistungen erlauben. In diesem Beitrag wird ein EDV-basiertes Analysetool für Dienstleistungsprozesse im Gesundheitsmanagement dargestellt, das...

It is considered the model of the universe in which the scales of length, time and mass are related by the special relativity constant c, by the Newton gravity constant G and by the quantum mechanics constant ¯ h. The model meets constraints from the current age of the universe, from the high-redshift supernovae data, and from primordial nucleosynthesis. The model predicts the fractal structure...

The following full text is a preprint version which may differ from the publisher's version. Abstract: We study the critical probability p c (M) in two-dimensional M-adic fractal percolation. To find lower bounds, we compare fractal perco-lation with site percolation. Fundamentally new is the construction of an computable increasing sequence that converges to p c (M). We prove that p c (2) > 0....

This paper presents a detailed study of the current-voltage (I-V) and capacitance-voltage (C-V) measurements made on CdS/CdTe based solar cell by numerical modeling. Implementation simulated having superstrate configuration was done with help SCAPS program using defect density model. The I-V characterisation includes window absorber layer optimisation various factors including impurity doping c...

It is well known that the permeability and density of an aggregate decreases with its size, affecting its settling velocity and coagulation rate (rate of particle capture) with other particles. This change in aggregate density with size can be described by fractal scaling relationships. Two distinctly different fractal scaling approaches, however, have been used to describe aggregate permeabili...
