Three works on religious themes : psalmus 150, string quartet on the life of Saint John Paul II and symphony “The Redemption”

Dans cette dissertation, je présente trois pièces sur des thèmes religieux composées au cours de ma maîtrise, ainsi que leur analyse : Psalmus 150 pour chœur de jeunes à trois voix, chœur d'adultes à huit voix et orgue ou piano ; Quatuor à Cordes sur la vie de Saint Jean-Paul II ; et la Symphonie « La Rédemption » pour orchestre et chœur. Malgré les particularités de chacune, elles présentent des aspects communs. L'idée principale des compositions fut d'éviter la rupture avec la tradition tout en apportant des nouvelles idées aux pièces, et de souligner l'importance de ma recherche sur la beauté. À cet égard, certaines techniques contemporaines, ainsi que les sonorités médiévales des quintes et octaves parallèles, furent utilisées en accord avec un langage tonal / modal qui demeure la base des trois compositions. Le chant Grégorien fut aussi une importante caractéristique de ces compositions. Pour mieux comprendre les analyses des œuvres, deux techniques seront expliquées, la douce toile de dissonances linéaires et l'harmonie d'accords parfaits majeurs. L'analyse de chaque pièce est divisée en deux parties. La première est une vision générale et la deuxième est plus détaillée. À la fin, les connaissances acquises par la composition des ces œuvres seront résumées et l'importance intemporelle de la beauté sera réaffirmée.

Beweisführung am seidenen Bit-String?

Seit über zehn Jahren wird in der rechtswissenschaftlichen Literatur der Beweiswert elektronischer Signaturen diskutiert. Alle bisherigen Abhandlungen sind jedoch rein theoretischer Natur. Auch beschäftigen sie sich nur mit einem Teil der Problematik, indem sie lediglich einen relativ kurzen Zeitpunkt nach der Signaturerzeugung betrachten. Praktische Erfahrungen mit der Beweisführung mittels elektronisch signierter Dokumente fehlen vollständig. Im Forschungsprojekt "ArchiSig" konnten nun erstmals praktische Erfahrungen gewonnen werden, die zur Schließung beider Lücken beitragen können. Der vorliegende Aufsatz stellt die aus einer Simulationsstudie gewonnenen Erkenntnisse tatsächlicher Beweiserhebungen mit elektronisch signierten Dokumenten dar und zeigt Konsequenzen für die sichere Langzeitaufbewahrung auf.

Virginia Apgar and string music

Virginia Apgar (1909-1974) is one of the most recognized American doctors, worldwide known by his contribution as the developer of the "Apgar test" a method used for the evaluation of newborns all over the world. She had many interests. She was anesthesiologist, a brilliant teacher and researcher, but she also loved lecture, basketball, fishing, golf, philately, and music. She played violin and cello and she interpreted that instruments in various chamber groups. Being motivated by one of her patients, Carleen Hutchinson, a science and music teacher, she made four instruments, viola, violin, cello, and mezzo violin. Nearly twenty years of her death, on October 24 1994, on the occasion of the annual meeting of the American Academy of Pediatrics and the issue by American Postal Service of a stamp honoring her, some of the preferred Dr. Apgar music pieces where performed with the instruments she made. Her life mixed different activities and let invaluable contributions for humanity.

Distributed parallelization of greedy Mobile Network Optimization algorithms

The Mobile Network Optimization (MNO) technologies have advanced at a tremendous pace in recent years. And the Dynamic Network Optimization (DNO) concept emerged years ago, aimed to continuously optimize the network in response to variations in network traffic and conditions. Yet, DNO development is still at its infancy, mainly hindered by a significant bottleneck of the lengthy optimization runtime. This paper identifies parallelism in greedy MNO algorithms and presents an advanced distributed parallel solution. The solution is designed, implemented and applied to real-life projects whose results yield a significant, highly scalable and nearly linear speedup up to 6.9 and 14.5 on distributed 8-core and 16-core systems respectively. Meanwhile, optimization outputs exhibit self-consistency and high precision compared to their sequential counterpart. This is a milestone in realizing the DNO. Further, the techniques may be applied to similar greedy optimization algorithm based applications.

An integer linear programming approach for approximate string comparison

We introduce a problem called maximum common characters in blocks (MCCB), which arises in applications of approximate string comparison, particularly in the unification of possibly erroneous textual data coming from different sources. We show that this problem is NP-complete, but can nevertheless be solved satisfactorily using integer linear programming for instances of practical interest. Two integer linear formulations are proposed and compared in terms of their linear relaxations. We also compare the results of the approximate matching with other known measures such as the Levenshtein (edit) distance. (C) 2008 Elsevier B.V. All rights reserved.

Fermion perturbations in string theory black holes

In this paper we study fermion perturbations in four-dimensional black holes of string theory, obtained either from a non-extreme configuration of three intersecting five-branes with a boost along the common string or from a non-extreme intersecting system of two two-branes and two five-branes. The Dirac equation for the massless neutrino field, after conformal re-scaling of the metric, is written as a wave equation suitable to study the time evolution of the perturbation. We perform a numerical integration of the evolution equation, and with the aid of Prony fitting of the time-domain profile, we calculate the complex frequencies that dominate the quasinormal ringing stage, and also determine these quantities by the semi-analytical sixth-order WKB method. We also find numerically the decay factor of fermion fields at very late times, and show that the falloff is identical to those showing for massless fields in other four-dimensional black hole spacetimes.

Comments on regularization of identity based solutions in string field theory

We analyze the consistency of the recently proposed regularization of an identity based solution in open bosonic string field theory. We show that the equation of motion is satisfied when it is contracted with the regularized solution itself. Additionally, we propose a similar regularization of an identity based solution in the modified cubic superstring field theory.
