This paper discusses risk perception comparing drivers with and without fines for speeding. The research aimed to show the interaction between speeding laws and speeding behavior. Speeders' explanations for their behavior revealed important factors in the determination of risk perception: control (driver-centered), risk minimization (drivers claimed there was no risk involved in the way they sp...

Truck or heavy vehicle crashes feature regularly in print, online and television media. When a heavy vehicle is involved in a serious crash, particularly one involving loss of human life, this often triggers public debate about the road conditions at the location of the crash, the factors that may have contributed to the crash and how the government is addressing the issue. Recently, there have...

Continuous GRASP (C-GRASP) is a stochastic local search metaheuristic for finding cost-efficient solutions to continuous global optimization problems subject to box constraints (Hirsch et al., 2006). Like a greedy randomized adaptive search procedure (GRASP), a C-GRASP is a multi-start procedure where a starting solution for local improvement is constructed in a greedy randomized fashion. In th...

The interval tree is an optimally eecient search structure proposed by Edelsbrunner 5] to retrieve intervals of the real line that contain a given query value. We propose the application of such a data structure to the fast location of cells intersected by an isosurface in a volume dataset. The resulting search method can be applied to both structured and unstructured volume datasets, and it ca...

Simulating the motion of cloth is an important component in virtual character animation. Believable animations are now expected in feature films. Games and virtual reality are next, but the computational costs are still high. In this thesis we present a number of methods which reduce these costs, without losing accuracy or generality. To this end, we introduce a novel adaptive implicit-explicit...

This dissertation develops approaches to testing the satisfiability and the containment of XPath queries in the presence of XML Schema definitions in order to speed up XML querying. XML provides a simple yet powerful mechanism for information storage, processing and delivery, and is a widely used standard data format. XPath is a basic language for querying XML data, and is embedded into many W3...

Differences to [1] A. fast spectral similarity: adaptive k-means (≤ 30 clusters), centers of the clusters are used as sample [2], likelihood of sample is computed as suggested in [3], with the modification that samples are weighted according to their priors B. Mel spectrogram (before DCT) used for fluctuation patterns C. 12 instead of 20 frequency bands used for the fluctuation patterns D. magn...

Finding a cell that reprograms in a nonstochastic manner without genetic manipulation has proven elusive. In this issue, Guo et al. report the identification of a cell defined by an ultrafast cycle whose progeny reprogram in a synchronous and rapid manner.

Any good medical ultrasound imaging system must be able to resolve anatomical structures properly, and simultaneously provide adequate frame rate so that moving structures can be studied with ease. In a conventional imaging system these properties are related by a trade-off, but is it possible to have one and the other by applying more advanced post-processing to acquired RF data? Two new metho...
