This is the latest in a series of reviews of research on graduated driver licensing (GDL) published in the Journal of Safety Research, covering the period January 1, 2010-June 1, 2012 and work in progress. The intent is to keep researchers and policy makers current regarding the existing state of knowledge about GDL, and to identify information gaps and areas where clarification of research fin...

Distributed Constraint Optimization Problems (DCOPs) are a general framework that can model a large class of Multi-agent Coordination Problems (MCPs). We propose a novel message-passing algorithm, the so-called Action-GDL, as an extension to the Generalized Distributive Law algorithm to efficiently solve MCPs. We show the generality of Action-GDL by proving that it has DPOP, the low-complexity,...

In this paper we made three main contributions (fully detailed in [5]). Firstly, we formulate a new algorithm, the so-called Action-GDL, that takes inspiration from GDL [1], extending and applying it to Distributed Constraint Optimization Problems (DCOPs). Secondly, we show the generality of Action-GDL showing how it generalizes DPOP[4], one of the low complexity, state-of-the-art algorithm to ...

In the current work, we present a comprehensive modeling framework to predict the effective gas diffusivity, as a function of liquid water saturation, based on realistic 3-D microstructures of the uncompressed as well as compressed gas diffusion layer (GDL). The presented approach combines the generation of a virtual microscopic GDL and different physical modeling. We develop a reduced model in...

Study refers comparison of three methods for glucose determination - precision (repeatability, reproducibility), traceability to SRM 965a NIST, comparability in blood-pools and in patients' samples: Electrochemical determination on Super GL (DiaSys, Germany) in hemolyzate - GL method, spectrophotometric determination using hexokinase (Glucose System Reagent 800, Olympus) - HKL method - and usin...

We present an experimental approach to study the three-dimensional microstructure of gas diffusion layer (GDL) materials under realistic compression conditions. A dedicated compression device was designed that allows for synchrotron-tomographic investigation of circular samples under well-defined compression conditions. The tomographic data provide the experimental basis for stochastic modeling...

BACKGROUND Current driver mortality estimates do not consider the great differences in exposure across the population, giving a false impression that driver deaths are lowest in the youngest age group. Interventions to reduce risk among the younger age group include graduated driver licensing (GDL) - a three-phase licensing system for novice drivers consisting of a learner's permit, a provision...

of the Dissertation Recent technological advances have fostered the emergence of Wireless Sensor Networks (WSNs), which consist of tiny, wireless, battery-powered nodes that are expected to revolutionize the ways in which we understand and construct complex physical systems. A fundamental property needed to use and maintain these WSNs is “localization”, which allows the establishment of spatial...

OBJECTIVE To determine the impact on young driver crashes of the three main driving restrictions in the New Zealand graduated driver licensing (GDL) system: night-time curfew, no carrying of young passengers, and a blood alcohol limit of 30 mg/100 ml. METHOD The database for this study was created by linking police crash reports to hospital inpatient records (1980-95). Multivariate logistic r...
