For some time, regulatory reforms in Europe have aimed at electricity market liberalisation. One of the many consequences is that increasingly spot market transactions replace long- term contracts, thus redefining the way wholesale electricity prices are f ...
We study changes in chief executive officer (CEO) contracts when firms transition from public ownership with dispersed owners to private ownership with strong principals in the form of private equity sponsors. The most significant changes are that a signif ...
Chaque année, plus de 300 projets sont réalisés par des étudiants de la section d’architecture de l’École polytechnique fédérale de Lausanne. Si la quantité d’idées et de ressources générées dans ce lieu d’enseignement et de recherche est considérable, ces ...
The study of biochemical dynamics by ultrafast spectroscopic methods is often restricted by the limited amount of liquid sample available, while the high repetition rate of light sources can induce photodamage. In order to overcome these limitations, we de ...
Scaling exponents for the conductivity and stiffness of replicated microcellular materials exceed commonly predicted values of 1 and 2. We show here that this is caused by the fact that, in replicated microcellular materials, the solid architecture varies ...
The special linear group G = SLn(Z[x(1), ... , x(k)]) (n at least 3 and k finite) is called the universal lattice. Let n be at least 4, and p be any real number in (1, infinity). The main result is the following: any finite index subgroup of G has the fixe ...
Increasingly detailed consumer information makes sophisticated price discrimination possible. At fine levels of aggregation, demand may not obey standard regularity conditions. We propose a new randomized sales mechanism for such environments. Bidders can ...
We propose a novel approach to synthesizing images that are effective for training object detectors. Starting from a small set of real images, our algorithm estimates the rendering parameters required to synthesize similar images given a coarse 3D model of ...
We formulate fuel optimal conflict free aircraft trajectory planning as a hybrid optimal control problem. The discrete modes of the hybrid system capture the air traffic procedures for conflict resolution, e. g., speed and turn advisories. In order to solv ...
Tracing the diffusion of legal concepts between different countries is at the core of comparative law. However, this diffusion is not limited to statutes and cases, but pervades through public spheres. This is visible in published materials of all sorts. H ...
