A precise data set describing the kinetics of the free radical copolymn. of acrylamide/acrylic acid (AM/AA) in the range of low total monomer concn. as a function of the pH, total monomer concn., initiator concn., and comonomer ratio is presented. Strong i ...
Chondrules, which are the major constituent of chondritic meteorites, are believed to have formed during brief, localized, repetitive melting of dust ( probably caused by shock waves(1,2)) in the protoplanetary disk around the early Sun. The ages of primit ...
In this paper, we address the problem of scrambling regions of interest in a video sequence for the purpose of preserving privacy in video surveillance. We propose an efficient solution based on transform-domain scrambling. More specifically, the sign of s ...
We consider an optimization problem arising in the design of controllers for OLED displays. Our objective is to minimize amplitude of the electrical current through the diodes which has a direct impact on the lifetime of such a display. Modeling the proble ...
Northwest Africa 479 (NWA 479) is a lunar meteorite recovered in 2000 from Morocco. This unbrecciated low-Ti basalt is paired with NWA 032. The texture of NWA 032/479 indicates a simple crystallization history and a fast cooling, followed by an impact even ...
Using pulsed-laser deposition, a two-step growth technique was applied to epitaxial SrTiO3 (STO) thin films on LaAlO3 substrates providing a way to obtain an effective strain relaxation in these films otherwise strained due to lattice mismatch between film ...
For companies proposing a large offer of products and services, it is important to identify the products for which the forecast quality is critical. The objective of this paper is to propose a strategic analysis of the products in order to determine priori ...
There are many questions in cell biology regarding the combined chemical-mechanical interactions between a cell and its surroundings. The mechanical feedback that a cell receives from its surroundings has a direct impact on its behaviour (eg. differentiati ...
Le chauffage à distance prend de plus en plus d'ampleur en Suisse actuellement. Ce rapport se propose de se concentrer sur les systèmes au bois. Le cas d'étude s'est porté sur l'installation de Porrentruy qui constitue le plus grand réseau de Suisse. Le pr ...
Metamorphic hydration and oxidation of ultramafic rocks produces serpentinites, composed of serpentine group minerals and varying amounts of brucite, magnetite, and/or FeNi alloys. These minerals buffer imetamorphic fluids to extremely reducing conditions ...
