bundling transaction management into a dedicated language or recoverable object manager, Quicksilver exposes the basic commit protocol and log recovery primi-tives, allowing clients and servers to tailor their recovery techniques to their specific needs. Servers can implement their own log recovery

In agent-based social simulation, crowd models are used to generate agent behaviors that should correspond closely to human crowds. Despite significant progress in this area, many existing crowd models do not yet account for important cultural factors in crowd behavior, and even more so, for mixed-culture crowds. Moreover, evaluation of crowd models accounting for culture is particularly difficult, e.g., as controlled experiments are more difficult to set up, due to lack of subjects from different cultures. In this paper we examine the impact of cultural differences on crowd dynamics in pedestrian and evacuation domains. We account for micro-level cultural attributes: personal spaces, speed, pedestrian avoidance side and group formations. We then quantitatively validate the macro-level predictions of an agent-based simulation utilizing these against data from web-cam movies of human pedestrian crowds recorded in five

ABSTRACT. The focus of the work was to investigate dependency between reindeer density and lichen (Cladonia spp.) ranges in the Finnish semidomesticated reindeer management area. Secondly, we formed a model on the recovery rate of ungrazed woodland lichen ranges (29 sites) after forest fires

ABSTRACT: During 1996–1999, hunters killed an estimated 24–30 % of the pre-hunt bull moose (Alces alces) in Game Management Unit 20A. As a result, the 1999 post-hunt bull:cow ratios declined to 24:100, well below the management objective of 30:100. During 2000 and 2001 we shortened the hunting

Abstract 13 Counteracting the worldwide trend of coral reef degeneration is a major challenge for the 14 scientific community. A crucial management approach to minimizing stress effects on healthy 15 reefs and helping the recovery of disturbed reefs is reef protection. However, the current rapid

Abstract By assuming that images of interest can be sparsely modelled by some transform, the sparsity-based regularization has been one promising approach for solving many ill-posed inverse problems in image recovery. One often-used type of systems for sparsifying images is wavelet tight frames

Abstract. Using structural geometric arguments, Whiteley showed that a line drawing is a correct projection of a spherical polyhedron if and only if it has a cross-section compatible with it. We here enlarge the class of drawings to which this test applies, including those of polyhedral disks

Abstract. Running the key-management service of cryptographic sys-tems in the cloud is an attractive cost saving proposition. Supporting key-recovery is an essential component of every key-management service. We observe that to verifiably support key-recovery in a public cloud, it is essential
