Density functional theory is applied to ion-induced nucleation of dipolar molecules. The predicted reversible work shows a sign preference, resulting in a difference in the nucleation rate by a factor of 10–10, for realistic values of model parameters. The sign effect is found to decrease systematically as the supersaturation is increased. The asymmetry of a molecule is shown to be directly res...

This paper investigates the controller synthesis of uncertain linear time-delay systems. Stabilizability criteria are derived based on a discretized Lyapunov functional approach. A new controller design method is developed. Numerical examples show that the results using the proposed method are less conservative than some existing ones.

This study differs from previous ones applying multivariate statistical analysis and multiple criteria decision-making (MCDM) methods. We use the Variable Consistency Dominance-based Rough Set Approach (VC-DRSA) to formulate airline service strategies by generating airline service decision rules thatmodelpassengerpreferences for airline servicequality. Flowgraphsare applied to inferdecision rul...

The “reproduction theory” was conceived and born in the research into educational inequalities in Western countries. Famous as the theory is, when it is to be applied in the research into education in China, a few factors must be taken into consideration: the subjects investigated must be educational inequalities that have come into being in the context of China; a shift in theoretical approach...

The concept of presence, i.e. the sensation of ‘being there’ in a mediated environment, has received substantial attention from the virtual reality community, and is becoming increasingly relevant both to broadcasters and display developers. Although research into presence is still at an early stage of development, there is a consensus that presence has multiple determinants. To identify and te...

We propose a pattern-based software development method comprising analysis (using problem frames) and design (using architectural and design patterns), of which especially evolving systems benefit. Evolution operators guide a pattern-based transformation procedure, including re-engineering tasks for adjusting a given software architecture to meet new system demands. Through application of these...

This study aims to explore visual complexity in streetscape composition using RMS contrast information and Fractal Analysis. The dataset was composed of 74 streetscape images, taken in Algeria and Japan in daytime and nighttime. The evaluation and analysis covered two phases: (1) Subjective quantification of perceived complexity using ranking method. (2) Visual complexity measurement based on R...

Transforming real-world requirements into specifications which are appropriate for subsequent software development is at the heart of Requirements Engineering. Doing it systematically remains an open challenge. In this paper we present a formal approach to systematise the move from requirements to specifications in the context of Jackson’s Problem Frames.

During the last half decade, various theories, concepts, and models have been established to make organizations more environmentally sustainable. The IS community had their share with the Green IS/IT domain. As it turned out most of these concepts took a very functional approach, not making a good fit for business process oriented organizations. To fill this gap the research stream of Green Bus...
