Despite the positive impact of information and communication technology (ICT) on an individual, organizational, and societal level (e.g., increased access to information, as well as enhanced performance and productivity), both scientific research and anecdotal evidence indicate that...

The equation of state is discussed for a system of degenerate fermions. The formation of bound states is allowed for; the latter may exhibit the Bose-Einstein condensation. A complex representation is given which includes bound and scattering two-particle states as well. Different (generalized)...

Nonequilibrium Green's function technique is applied to the many-exciton system under the action of an externally driven light field. Starting with Dyson's equation for the nonequilibrium exciton propagator the shift and damping of exciton-levels due to exciton-exciton interaction are calculated...

Many methods to elicit preference models in multi-attribute decision making rely on evaluations of a set of sample alternatives by decision makers. Using orthogonal design methods to create this set of alternatives might require respondents to evaluate unrealistic alternatives. In this paper, we...

The struggle for commercial supremacy through information is being fought on two points: Information management and enabling technologies. Over the last years, there has been an increasing focus on information architecture (IA) to help organisations distinguish and manage information as...

Companies increasingly show that the choice of the right business model is a crucial success factor. Especially the software industry is characterized by a high degree of dynamics within their business activities. For staying competitive within the continuously changing business environment,...

Pressure amongst competitors combined with a rapidly changing economy drive enterprises to continuously adapt their current business models to prevail over competitors. Business models nowadays must be flexible enough to cope with external or internal changes and therefore should be managed and...
