Gnu Data Language (GDL) is an open-source interpreted language aimed at numerical data analysis and visualisation. It is a free implementation of the Interactive Data Language (IDL) widely used in Astronomy. GDL has a full syntax compatibility with IDL, and includes a large set of library routines targeting advanced matrix manipulation, plotting, time-series and image analysis , mapping, and da...

A one dimensional isothermal mathematical modeling of cathode side of a Proton Exchange Membrane (PEM) fuel cell is developed for the water management problem. Water transport is investigated in both cathode Gas Diffusion Layer (GDL) and membrane through solving appropriate equations for fluid flow and mass transport in GDL and water transport within the membrane. The gaseous mixture flowing in...

The over-representation of young novice drivers in road collisions is a public health risk in Great Britain (GB), and worldwide. The key contributory factors to this problem are known and are cross-cultural; they are youth and inexperience. This report reviewed and synthesised evidence of effectiveness for three approaches to tackling young and novice driver safety, for consideration in GB: 1.P...

Understanding multiphase flow and gas transport occurring in electrodes is crucial for improving the performance of proton exchange membrane fuel cells. In present study, a pore-scale model using lattice Boltzmann method (LBM) was proposed to study coupled processes air–water two-phase oxygen reactive porous structures diffusion layer (GDL) fractures microscopic (MPL). Three-dimensional numeric...

We present a first attempt at the compilation of the Game Description Language (GDL) using a bottom-up strategy. GDL is transformed into a normal form in which rules contain at most two predicates. The rules are then inverted to allow forward chaining and each predicate will turn into a function in the target language. Adding a fact to the knowledge base corresponds to triggering a function cal...

In the single-agent case general game playing and action planning are two related topics, so that one might hope to use the established planners to improve the handling of general single-player games. However, both come with their own description language, GDL and PDDL, respectively. In this paper we propose a way to translate single-player games described in GDL to PDDL planning tasks and prov...

The Game Description Language GDL is the standard input language for general game-playing systems. While players can gain a lot of traction by an efficient inference algorithm for GDL, state-of-the-art reasoners suffer from a variant of a classical KR problem, the inferential frame problem. We present a method by which general game players can transform any given game description into a represe...

We describe a multilevel algorithm compiling a general game description in GDL into an optimized reasoner in a low level language. The aim of the reasoner is to efficiently compute game states and perform simulations of the game. This is essential for many General Game Playing systems, especially if they use simulation-based approaches. Our compiler produces a faster reasoner than similar appro...

PROBLEM California's graduated driver licensing (GDL) program was implemented to reduce the high crash risk of teenage drivers. The program enhancements made in 1998 were evaluated in this study using methods that rule out the noticeable downward trend in California teen's fatal/injury crash rates as a possible explanation for any observed crash reductions that could otherwise be mistaken for p...
