A considerable amount of research has been conducted to demonstrate the development of bioreactor landfills promoted by leachate recirculation [1-10]. The effectiveness of leachate recirculation has been well documented in lysimeter studies [1, 5, 11, 12], test cell studies [2, 13, 14-16] and full-scale studies [17-20]. However, the results from these investigations might not be applied appropr...

Air distribution in commercial airliner cabins is very important for the comfort and health of passengers and crew. Experimental measurements, CFD simulations, and inverse modeling are state-of-the-art methods available for studying the air distribution. This paper gave an overview the different experimental models, such as scale models, simplified models, full-scale mockups, and actual air cab...

We investigate the effective stress-strain behavior of cellular elastomers, structured with a periodic pattern of elliptic holes by means of full scale simulations under small deformations. First, we show that the elastic response behaves non trivially with the pore geometry. In particular, we show that auxetic and anistropic responses arise for a broad range of parameters, when the microstruct...

The aim of this symposium is to initiate the discussion on learning with simulations in the medical sector. Indeed, this domain represents a very complex and dynamic environment dealing with a great variety of knowledge (declarative, pragmatic, procedural, gestural, etc.) that can be learned under diverse pedagogical forms. The four presentations describe various forms of computer-based technol...

This paper describes a method of comparing two acceleration time histories to determine if they describe similar physical events. The method can be used to assess the repeatability of full-scale crash tests and it can also be used as a criterion for assessing how well a finite element analysis of a collision event simulates a corresponding full-scale crash test. The method is used to compare a ...

The possibility of using window comparators for onchip (and potentially on-line) response evaluation of analogue circuits is investigated. No additional analogue test inputs are required and the additional circuitry can be realised either by means of standard digital gates taken from an available library or by full custom designed gates to obtain an observation window tailored to the applicatio...

In this paper, an effective and computationally efficient method for the recovery of lost motion vectors in video codecs is proposed. The method clusters motion vectors into groups exhibiting coherent motion. The cluster with the majority of motion vectors is selected and a statistical method is applied to the group to estimate the lost motion vector. Simulation results are presented, including...

We consider the problem of finding known asteroids in a given region of space and time. Each asteroid’s trajectory is known precisely at any given point in time, but evaluation of the model describing its location is prohibitively expensive at query time. We propose a framework for sampling the base model and indexing the resulting “observations.” Our system includes 11 million simulated astero...

We introduce a high-performance implementation of a loosely coherent statistic sensitive to signals spanning a finite-dimensional manifold in parameter space. Results from full-scale simulations on Gaussian noise are discussed, as well as implications for future searches for continuous gravitational waves and related searches for slowly modulated signals, such as emitted by radio pulsars. We de...

Obstacle detection is an important visual task for pedestrians. An experiment was carried out to measure the ability to detect peripheral obstacles under variations of illuminance and scotopic/photopic luminance ratio and with older and younger test participants. The LED array used in this work enabled scotopic/photopic ratio to be varied whilst chromaticity was held constant. The tests employe...
