AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Conventional RF power amplifiers usually give their maximum efficiency near the maximum output power level. When the output power decreases, the efficiency drops sharply. Deep class AB or B PAs improve their efficiency by a self-adaptation of the current d ...
It is widely accepted that metabolic rates scale across species approximately as the 3/4 power of mass in most if not all groups of organisms. Metabolic demand per unit mass thus decreases as body mass increases. Metabolic rates reflect both the ability of ...
Optimal management strategies for a group of bridges that may incur damage from flooding during a 15-year period were determined using three approaches, and then the strategies were compared. The three approaches are the supply and demand system approach a ...
Microstereolithography is a new microfabrication process that evolved from the rapid prototyping industry. The first developments in this technology started in 1993 and different research teams around the world have developed microstereolithography machine ...
A detailed study has been made of the onset and behaviour of (m = 3, n = 2) neoclassical tearing modes (NTMs) on JET, validating many of the underlying concepts in NTM physics. In particular, fitting onset thresholds in terms of the correctly motivated phy ...
As demand increases for positioning rescue crews, military users, and individuals with special needs, miniaturized low-power inertial measurement units (IMUs) coupled with GPS receivers and other sensors can provide accurate position in both indoor and out ...
We present a 3D geometric flow designed to evolve in Diffusion Tensor Magnetic Resonance Images(DT-MRI) along fiber tracts by measuring the diffusive similarity between voxels. Therefore we define a front propagation speed that is proportional to the simil ...
We propose a measure of quality for OD trip tables estimated from link counts. This measure, called the total demand scale is based only on the estimated OD trip table and on the assignment matrix used to estimate it. It is independent of the OD estimation ...
We analyse the optimal Initial Public Offering (IPO) mechanism in a multidimensional adverse selection setting where institutional investors have private information about the market valuation of the shares, the intermediary has private information about t ...
The following work deals with the characterisation of the behaviour of road bases granular material, made of tunnel excavation material and loaded by passing vehicle axles. This granular media, don't correspond generally to the standards demanded for the c ...
