In this paper, we consider sigma-delta (SD) quantization of geometrically uniform (GU) finite frames. In the first part, we prove that under some conditions, the variant I and II permutation modulation (PM) codes, first introduced by Slepian (1968, 1965), ...
Variable block size motion estimation (VBSME) in state-of-the-art video coding standards is one of the key features which improves the coding efficiency significantly compared to the previous standards. VBSME hardware design is a challenging task due to it ...

The Steel Slit Panel (SSP) is studied for its viability as a lateral force resisting system (LFRS) for regions of high seismicity. Anticipated benefits for the SSP are architectural flexibility, as well as repair and retrofit possibilities. This paper is f ...
This book examines experimental design methodologies in the field of architecture and their implementation in academic settings. Theoretical considerations by guest essayists and numerous examples of conceptual designs complement our holistic approach to t ...
This publication compiles the results of the SpaceWatch event 2008. The first edition has taken place in Lausanne on May 15th, 2008. The present book is composed of two parts. Part I presents the scientific comments on the press review highlighting the con ...
We present a novel error-correction scheme for sensor networks called Multi-hop Hybrid ARQ (MHARQ). Rather than immediately discard a received corrupt packet, a node buffers it. When two corrupt versions of a packet have been received, a procedure attempts ...
This work follows from a research project, in which we investigate the underlying mechanisms of human imitation and develop a neural model of its core neural circuits. The present paper presents a model of a neural mechanism by which an imitator agent can ...
For accurate a posteriori error analysis of the reduced basis method for coercive and non-coercive problems, a critical ingredient lies in the evaluation of a lower bound for the coercivity or inf-sup constant. In this short Note, we generalize and improve ...
Micro-system for active vibratory insulation, characterised in that it comprises a stand which includes a frame (1) and at least two beams (2a, 2b) which interlock and carry or are intended to carry an element requiring stabilisation (3), said beams (2a, 2 ...
In this paper, we propose a theoretical model for the error propagation phenomenon generated by a frame loss in a distributed video coding framework. Using rate-distortion functions, we analyze the impact of a frame loss on the average distortion of a grou ...
