Abstract:
Due to the growing importance of condition monitoring in industries, lots of condition monitoring techniques abound in today’s engineering literature. Actually, recent trends indicate that more condition monitoring strategies are being developed or proposed; this trend currently shows no signs of slowing down and is likely to continue for a long time. A majority of the condition monitoring methodologies are developed specifically for rotating machinery problems; fortunately, this has led to an improved understanding of the observed machineries and what to look out for while these machineries a

The aim of this work is to produce X-ray laser source from a plasma produced by focusing a pulsed laser beam on a solid target.

Detailed simulations of Ni-like Mo X-ray laser media are undertaken using the EHYBRID code which is a hydrodynamic code. X-ray resonance lines between 25 &Aring<br>and 40 &Aring<br>emitted from the molybdenum plasma have been obtained and analysed.

Abstract:
The monograph is devoted to the study of nonlinear first order systems in the plane where the principal term is the gradient of a positive and positively 2-homogeneous Hamiltonian (or the convex combination of two of such gradients). After some preliminaries about positively 2-homogeneous autonomous systems, some results of existence and multiplicity of T-periodic solutions are presented in case of bounded or sublinear nonlinear perturbations. Our attention is mainly focused on the occurrence of resonance phenomena, and the corresponding results rely essentially on conditions of Landesman-Laz

Despite this, the diagnosis and prognosis of some conditions associated with sudden cardiac death remain challenging or indeed uncertain.

Although the PI controller is well established and easy to use under normal grid conditions, it leads to system instability under abnormal grid conditions.

One of the most extreme situations can be found for NMR spectra of samples from metabolomics studies, from which approximately fifty compounds can be detected in a single measurement.

Abstract:
La conservation longue duree d'organes a basses temperatures est un des parametres qui permettront le developpement des greffes. Cette cryopreservation necessite de perfuser l'organe avec un cryoprotecteur, plus ou moins toxique, qui va gener l'organisation des molecules d'eau en cristaux de glace. En refroidissant suffisamment rapidement l'organe, il est alors possible de le vitrifier totalement. Dans ce travail les etudes ont ete realisees sur des solutions cryoprotectrices a base de 26 et 30% de 2,3-butanediol. Leurs conditions de vitrifications et de rechauffement sans cristallisation ont

Abstract:
L'attraction d'ondes dans des systèmes contra-propagatifs est un phénomène général, établi initialement en Physique dans le contexte de l'attraction de polarisation entre deux ondes contra-propagatives se propageant dans des fibres optiques. Ce phénomène a été observé expérimentalement, et ses propriétés étudiées via des simulations numériques. Les modèles qui s'y rattachent sont des systèmes hyperboliques d'équations aux dérivées partielles, avec des conditions aux bords dépendant du temps sur un intervalle fini. Le mécanisme sous-jacent peut être expliqué par l'existence de tores singuliers

Abstract:
Dans une 1ere partie, on construit des formulations variationnelles associées aux équations de Maxwell résonantes. Les équations dégénèrent dans le domaine, entraînant la non-unicité et la singularité des solutions. L’ajout de viscosité permet de les désingulariser, et par un procédé d’absorption limite, lorsque ce paramètre de viscosité tend vers zéro, on identifie la solution physique. Mais la dégénérescence sépare le problème à la limite en deux équations sur des domaines différents couplées par leur interface, le long de laquelle les solutions explosent. Ce travail caractérise la solution

Abstract:
Master's thesis deals with influence of various factors on the concrete compressive strength and modulus of elasticity. This work concentrates mainly on the influence of early curing and air entrainment of concrete. One part of this work is the evaluation of laboratory measurement, which was carried out on cubes of standard and norm prisms. The development of elastic moduli was monitored in time to 730 days of age with respect to air entrainment and curing conditions. The second part of the experiment deals with a comparison of theoretical creep curves depending on the value of the modulus of

Abstract:
[EN] Phononic crystals are artificial materials formed by a periodic arrangement of inclusions embedded into a host medium, where each of them can be solid or fluid. By controlling the geometry and the impedance contrast of its constituent materials, one can control the dispersive properties of waves, giving rise to a huge variety of interesting and fundamental phenomena in the context of wave propagation. When a propagating wave encounters a medium with different physical properties it can be transmitted and reflected in lossless media, but also absorbed if dissipation is taken into account.

碩士<br>國立東華大學<br>電機工程學系<br>94<br>The mixed-acid is defined as the mixture solution of many kinds of acid, such as nitric acid, acetic acid, phosphoric acid etc., they are mainly used in semiconductor and flat panel display manufacturing process as to etch Cr, Al, and ITO. In the process, the normal setting of the system will shift as the batch processing keep going, which will cause critical dimension and yield variation, therefore it is necessary to set up a monitor system to monitor the mixed-acid system to avoid normal condition shift. The monitor system should have the flexibility to integr
