This paper addresses the problem of assessing distortions produced by watermarking 3D meshes. In particular, a new methodology for subjective evaluation of the quality of 3D objects is proposed and implemented. Two objective metrics derived from measures o ...
We present a quality management method for multimedia applications. The method takes as input an application software composed of actions. The execution times of actions are unknown increasing functions of quality level parameters. The method allows the co ...
Networks need to accommodate diverse applications with different Quality-of-Service (QoS) requirements. New ideas at the physical layer are being developed for this purpose, such as diversity embedded coding, which is a technique that combines high rates w ...
In several industrial case studies, we put in evidence that microsystem manufacturing costs skyrocket because of low yields. Sometimes product functionalities are badly defined ; sometimes metrology systems, in spite of their high cost, happen not to measu ...
Optimization in the process industry has received a lot of attention in recent years because, in the face of growing competition, it represents a natural choice for reducing production costs, improving product quality, and meeting safety requirements and e ...
Very large mol. systems can be calcd. with the so called CNDOL approx. Hamiltonians that have been developed by avoiding oversimplifications and only using a priori parameters and formulas from the simpler NDO methods. A new diagonal monoelectronic term na ...
The design, fabrication and experimental investigation of 21MHz MEM Bulk Lateral Resonators (BLR) on 1.5 mu m Silicon-On-Insulator (SOI) Fragmented Membranes with 100nm air-gaps are reported(#). Quality factors as high as 33'000 are measured under vacuum a ...

Artificial immune systems (AIS) use the concepts and algorithms inspired by the theory of how the human immune system works. This document presents the design and initial evaluation of a new artificial immune system for collaborative spam filtering. Collab ...
In this paper, we propose a probabilistic framework targeting three important issues in the computation of quality and trust in decentralized systems. Specifically, our approach addresses the multi-dimensionality of quality and trust, taking into account c ...
The Direct Metal Laser Sintering process (DMLS) is a Rapid Manufacturing (RM) technique. A 3D object is built layer by layer through laser consolidation of metallic powders. Several industrial DMLS stations are commercialised. The current performances of t ...
