< A statistical model is developed for estimating GDL thermal conductivity. < The model considers the statistical distribution of GDL geometrical parameters. < Angle and aspect ratio distributions are measured for some GDLs. < The dependency of thermal conductivity on geometrical parameters is considered. < New techniques are introduced for GDL geometrical property measurements. a r t i c l e i...

Responsive or smart contrast agents (SCAs) provide new opportunities in magnetic resonance imaging (MRI) to examine a number of physiological and pathological events. However, their application in vivo remains challenging. Therefore, much research is focused on the optimization of their properties, to enable their use in additional imaging modalities, pre-targeted delivery, or to increase the l...

The game description language GDL has been developed as a logicbased formalism for representing the rules of arbitrary games in general game playing. A recent language extension called GDL-II allows the description of nondeterministic games with any number of players who may have incomplete, asymmetric information. In this paper, we apply model checking to address the problem of verifying that ...

CONTEXT Graduated drivers license (GDL) programs have been shown to reduce motor vehicle fatalities among 15- to 17-year-olds. However, the 20 most rural states have been the least likely to enact more stringent GDL policies. PURPOSE Estimate the relationship of GDL programs and the number of traffic fatalities among 15- to 17-year-olds on rural interstate and noninterstate roadways. METHOD...

The Game Description Language (GDL) is a special purpose declarative language for defining games. GDL is used in the AAAI General Game Playing Competition, which tests the ability of computer programs to play games in general, rather than just the ability to play a specific game. Participants in the competition are provided with a previously unknown game specified in GDL, and are required to dy...

Oxygen transport across the cathode gas diffusion layer (GDL) in polymer electrolyte membrane (PEM) fuel cells was examined by varying the O2/N2 ratio and by varying the area of the GDL extending laterally from the gas flow channel under the bipolar plate (under the land). As the cathode is depleted of oxygen, the current density becomes limited by oxygen transport across the GDL. Oxygen deplet...

GDL-III, a description language for general game playing with imperfect information and introspection, supports the specification of epistemic games. These are characterised by rules that depend on the knowledge of players. GDL-III provides a simpler language for representing actions and knowledge than existing formalisms: domain descriptions require neither explicit axioms about the epistemic ...

An experimental setup to determine thermal conductivity and thickness of a gas diffusion layer (GDL) as a function of compression was developed and calibrated. The actual thermal conductivities, based on compressed thickness, of plain Toray TGP-H gas diffusion layer (GDL) at compression pressures of 0.04 to 1.5 MPa and over temperature range of 25 C to 75 C are reported in this paper. The therm...

The gas diffusion layer (GDL) is an essential element of the electrodes in polymer electrolyte membrane (PEM) fuel cells. The GDL makes electrical contact with the catalyst layers to provide a larger area to carry the electronic current from the catalyst to the bipolar plates reducing the resistance for current flow. The GDL must be porous to permit the flow of reactant gas from the gas flow ch...

This paper presents our new proposition of human body poses and gesture description methodology for Natural User Interfaces. Our approach is based on forward chaining inferring schema performed on the set of rules that are defined with formal LALR grammar. The set of rules is called Gesture Description Language (GDL) script while automated reasoning module with heap-like memory is a GDL interpr...
