The aim of this PhD thesis is to contribute to a better understanding of turbulent mixing in lakes. This research is focused on the response dynamics of the stratified Lake of Geneva to strong wind forcing. We especially investigated the dynamics of small ...
In this paper an objective metric to measure the perceptual quality of watermarked 3D meshes is presented. The metric, which is based on a black-box approach, relies on the measurement of the roughness of 3D meshes before and after the insertion of the wat ...
Manageability directly influences a system's reliability, availability, security, and safety, thus being a key ingredient of system dependability. Alas, we do not have today a good way to measure manageability or reason quantitatively about it, and this is ...
This paper presents a new approach for the design of a full reference objective quality metric for the assessment of color pictures. Our goal is to build a multi-channel metric based on the perceptual weighting of single-channel metrics. A psycho-visual ex ...
Accurate assessment of the macromolecule contributions in short echo-time proton MRS spectra is important for a reliable quantification of the neurochemical profile. The aim of the present study was to assess two approaches based on using LCModel, which ta ...

This paper presents a measurement system design methodology that incorporates damage scenarios. One of the goals of a measurement system is to detect damage for safety and for management of maintenance activities. This study builds upon previous research a ...
A weak metric on a set is a function that satisfies the axioms of a metric except the symmetry and the separation axioms. The aim of this paper is to present some interesting weak metrics and to study some of their properties. In particular, we introduce a ...
Ultrasonic machining is performed using closed-loop Z-axis position and force control. Micromachining requires tools smaller than 100 micrometers in diameter, necessitating the use of forces in the low mN range. ...

We consider the problem of determining the “closest”, or best Internet host to connect to, from a list of candidate servers. Most existing approaches rely on the use of metric, or more specifically Euclidean coordinates to infer network proximity. This is ...
Evaluation is a central issue in the design, implementation, and performance assessment of all systems. Recently, a number of metrics have been proposed to assess the performance of segmentation algorithms for image and video data. This paper provides an o ...
