Virtual re-embedding, i.e., adding social cues to a website, has been suggested as a possible strategy to increase consumer trust in online-vendors. Numerous online retailers meanwhile incorporate this strategy, for example by adding photographs and names of customer service agents or by creating chat and callback opportunities. Yet, little is is known(More)
New technologies for distributed object computing (DOC) challenge new approaches to integrate Geographical Information Systems (GIS) and simulation tools for spatio-temporal modeling. Several standardization initiatives work on specifying interfaces and defining service architectures for appropriate components. Currently, the most promising attempts are(More)
This paper presents an extension of the process-dissociation procedure with wordstem completion, which makes possible the measurement of the stochastic relationship between consciously controlled and automatic processes. By means of an indirect wordstem completion test, the conditional probabilities of conscious remembering with and without automatic(More)
The goal of the study was to examine connections between ion channel activity and the proliferation of human chondrocytes. Chondrocytes were isolated form human osteoarthritic knee joint cartilage. In this study the concentration-dependent influence of the ion channel modulators tetraethylammonium (TEA), 4-aminopyridine (4-AP), 4',4'(More)
OBJECTIVE To evaluate the apical sealing ability of 2 epoxy resin-based root canal sealers used with 2 different warm gutta-percha obturation techniques and cold lateral condensation. METHOD AND MATERIALS The root canals of 72 freshly extracted single-root incisors were prepared and randomly assigned to 6 experimental groups. Root canal fillings were(More)
A point-to-point routing algorithm with three new features is presented. First, the router makes optimal use of oversized, rectangular contacts. Second, it allows different wire width on different layers, with the layers having complete freedom as to routing direction. These two features make the algorithm attractive for MOS layout applications. Finally it(More)
This paper looks at the use of drop-on-demand technology in automated life science laboratories. One significant feature of the droplets generated is the enormously high uniformity under constant conditions. However, there is also a relatively strong dependency on environmental conditions. Many different kinds of liquids are used in laboratory applications,(More)
An expanded nonlinear model inversion flight control strategy using sliding mode online learning for neural networks is presented. The proposed control strategy is implemented for a small unmanned aircraft system (UAS). This class of aircraft is very susceptible towards nonlinearities like atmospheric turbulence, model uncertainties and of course system(More)
An expanded model inversion flight control strategy using sliding mode online learning is presented and implemented for an small unmanned aircraft system (UAS). These low-cost aircraft are very susceptible towards nonlinearities like atmospheric turbulence, model uncertainties or system failures, so adaptive flight control strategies possess a high(More)
