On the Structure of the Capacity Region of Asynchronous Memoryless Multiple-Access Channels
Bixio Rimoldi, Ninoslav Marina
The asynchronous capacity region of memoryless multiple-access channels is the union of certain polytopes. It is well-known that vertices of such polytopes may be ap- proached via a technique called successive decoding. It is also known that an extension o ...
2009Unitary descent properties
Let k be a field of characteristic /=2 and let W(k) be the Witt ring of k and L a finite extension of k. If L/k is a Galois extension, then the image of rL/k is contained in W(L)Gal(L/k) where rL/k:W(k)→W(L) is the canonical ring homomorphism. Rosenberg an ...
2009Visual contracts (VCs)
Model-Driven Engineering (MDE) harbors the promise of developing software-based systems with little or no coding. Instead of coding, it is envisioned that software engineers build models that are automatically translated into code. The modeling notation of ...
EPFL2008Feed-Oriented Awareness Services for eLogbook Mobile Users
Denis Gillet, Christophe Salzmann
The eLogbook is a collaborative Web-based environment deployed by Swiss Federal Institute of Technology in Lausanne (EPFL). It consists of an activity- oriented space where a community of educators, teaching assistants and students can form groups, conduct ...
2007Symmetry breaking in mechanical systems
The first part of this thesis studies the problem of symmetry breaking in the context of simple mechanical systems with compact symmetry Lie group G. In this part we shall assume that the principal stratum of the G-action on the configuration space Q of a ...
EPFL2005Réseaux idéaux sur des corps CM et des corps totalement réels
This thesis deals with the study of ideal lattices over number fields. Let K be a number field, which is assumed to be CM or totally real. An ideal lattice over K is a pair (I,b), where I is a fractional ideal of K and b : I × I → R is a symmetric positive ...
EPFL2005Anneau de Witt des G-formes et multiples de G-formes trace
This thesis deals with the study of G-forms and particulary the trace form of a G-Galois algebra. Let k be a field of characteristic not two. Let G be a finite group and L a G-Galois algebra over k. We define the trace form qL by qL(x, y) = TrL/k(xy) for a ...
