A Process Sensor for Locating the Liquid-Solid Boundary through the Mold of a Casting
Accurate process control of single-crystal and directionally-solidified castings requires knowledge of the exact location of the solidifying front. If the front advances too rapidly, single crystal growth in a preferred orientation degenerates into the formation of polycrystals. A solidification front which moves more slowly than necessary is wasteful of the casting resources. A sensing technology is being developed which determines the location of the boundary between a solidifying crystal and liquid metal. The sensing method utilizes the ordered pattern of x-rays diffracted from the solid as an absolute indicator of the liquid-crystal interface.</p
The Epsilon Calculus and Herbrand Complexity
Hilbert's epsilon-calculus is based on an extension of the language of
predicate logic by a term-forming operator . Two fundamental
results about the epsilon-calculus, the first and second epsilon theorem, play
a role similar to that which the cut-elimination theorem plays in sequent
calculus. In particular, Herbrand's Theorem is a consequence of the epsilon
theorems. The paper investigates the epsilon theorems and the complexity of the
elimination procedure underlying their proof, as well as the length of Herbrand
disjunctions of existential theorems obtained by this elimination procedure.Comment: 23 p
Syndrome respiratoire aigu après inhalation de sprays imperméabilisants
Au cours de l'hiver 2002-2003, le Centre suisse d'information toxicologique a enregistré une augmentation inhabituelle de troubles respiratoires après exposition à des sprays imperméabilisants utilisés pour l'imprégnation du cuir et des textiles. Plus de 150 cas ont ainsi été rapportés. De telles épidémies sont déjà survenues au cours des vingt dernières années dans divers pays. Sur le plan clinique, des symptômes de toux, dyspnée et fièvre apparaissent dans le minutes ou les heures qui suivent l'exposition. Certains patients présentent une détresse respiratoire aiguë nécessitant une hospitalisation en soins intensifs. L'évolution clinique est favorable en quelques jours dans la majorité des cas, mais une dyspnée ou une toux chroniques pourraient persister chez certains patients. Un récent changement de formulation chimique semble être la cause de l'épidémie survenue en Suisse. Les produits incriminés ont été retirés de la vente. De nouveaux cas pourraient toutefois survenir à l'avenir en lien avec l'utilisation accrue de sprays imperméabilisants durant l'hiver et la possible commercialisation de nouveaux produits. [¨Résumé des Auteurs] A la suite de l'épidémie survenue en Suisse, l'Office fédéral de la santé publique a fait classer tous les sprays imperméabilisants pour cuirs et textiles dans la classe de toxicité 5S. Leurs emballages comporteront donc davantage d'avertissements aux utilisateurs. Il est actuellement recommandé d'employer ces sprays à l'air libre, d'éviter de s'exposer au brouillard de vaporisation (ne pas employer le spray contre le vent), et de bien laisser sécher les articles imperméabilisés à l'extérieur. L'emploi à l'intérieur est à éviter. Il ne suffit pas d'ouvir une fenêtre. Les personnes atteintes de maladies respiratoires (par exemple, asthme) devraient éviter d'utiliser elles-mêmes ces produits et ne pas se tenir à proximité d'un endroit où ils sont employés.

<![CDATA[This book presents a thorough discussion of utility cycling, cycling in the urban environment, and everyday mobility. It is based on large survey answered by 14,000 participants in the bike to work action in Switzerland, and quantifies the various dimensions of utility cycling.
It proposes an innovative theoretical framework to analyse and understand the various dimensions of the uses of bikes and their diversity. It addresses the factors that motivate commuters to get on their bike, and highlights the barriers to this practice between deficient infrastructures and lack of legitimacy. This research makes a diagnosis and discusses the way to develop this sustainable mode of transportation.
By combining quantitative results in the form of tables, figures, and maps, and including qualitative results in the form of quotations from survey participants, this book provides a thorough and enjoyable read. It will be of interest to researchers, policy makers, advanced students in the field of urban planning, social sciences, and transportation
Consolidation of Belief in Two Logics of Evidence
Recently, several logics have emerged with the goal of modelling evidence in a more relaxed sense than that of justifications. Here, we explore two of these logics, one based on neighborhood models and the other being a four-valued modal logic. We establish grounds for comparing these logics, finding, for any model, a counterpart in the other logic which represents roughly the same evidential situation. Then we propose operations for consolidation, answering our central question: What should the doxastic state of a rational agent be in a given evidential situation? These operations map evidence models to Kripke models. We then compare the consolidations in the two logics, finding conditions under which they are isomorphic. By taking this dynamic perspective on belief formation we pave the way for, among other things, a study of the complexity, and an AGM-style analysis of rationality of these belief-forming processes
Octahedral conversion of a-SiO2-host matrix by pulsed ion implantation
This is the abstract. The results of measurements of X-ray photoelectron
spectra (XPS) of a-SiO2-host material after pulsed implantation with [Mn+] and
[Co+, Mn+]-ions as well as DFT-calculations are presented. The low-energy shift
is found in XPS Si 2p and O 1s core-levels of single [Mn+] and dual [Co+, Mn+]
pulsed ion-implanted a-SiO2 (E = 30 keV, D = 2*10^17 cm^-2) with respect to
those of untreated a-SiO2.The similar changes are found in XPS Si 2p and O 1s
of stishovite compared to those of quartz. This means that the pulsed
ion-implantation induces the local high pressure effect which leads to an
appearance of SiO6-structural units in alpha-SiO2 host, forming
"stishovite-like" local atomic structure. This process can be described within
electronic bonding transition from the four-fold "quartz-like" to six-fold
"stishovite-like" high-pressure phase in SiO2 host-matrix. It is found that
such octahedral conversion depends on the fluence and starts with doses higher
than D = 3*10^16 cm^-2.Comment: 15 pages, 6 figures, 1 table, accepted in phys. stat. solidi (b
Monte Carlo simulation of kilovolt electron transport in solids
A Monte Carlo procedure to simulate the penetration and energy loss of low¿energy electron beams through solids is presented. Elastic collisions are described by using the method of partial waves for the screened Coulomb field of the nucleus. The atomic charge density is approximated by an analytical expression with parameters determined from the Dirac¿Hartree¿Fock¿Slater self¿consistent density obtained under Wigner¿Seitz boundary conditions in order to account for solid¿state effects; exchange effects are also accounted for by an energy¿dependent local correction. Elastic differential cross sections are then easily computed by combining the WKB and Born approximations to evaluate the phase shifts. Inelastic collisions are treated on the basis of a generalized oscillator strength model which gives inelastic mean free paths and stopping powers in good agreement with experimental data. This scattering model is accurate in the energy range from a few hundred eV up to about 50 keV. The reliability of the simulation method is analyzed by comparing simulation results and experimental data from backscattering and transmission measurements
