Grid Computing: Experiment Management, Tool Integration, and Scientific Workflows

Editura: SPRINGER PG

Anul aparitiei: 2007

Grid computing has become a topic of significant interest in the scientific community as a means of enabling application developers to aggregate resources scattered around the globe for solving large-scale scientific problems. This monograph addresses four critical software development aspects for the engineering and execution of applications on parallel and Grid architectures. A new directive-based language called ZEN is proposed for compact specification of wide value ranges of interest for arbitrary application parameters, including problem or machine sizes, array or loop distributions, software libraries, interconnection networks, or target execution machines. Based on the ZEN language, a novel experiment management tool called ZENTURIO is developed for automatic experiment management of large-scale performance and parameter studies on parallel and Grid architectures. This tool has been validated with respect to functionality and usefulness on several real-world parallel applications from various domains, including theoretical chemistry, photonics, finances, and numerical mathematics. Depending on the ZENTURIO experiment management architecture a generic optimization ...

Is There a Difference in the Weather Effect Between Developed and Emerging Markets

Editura: KESSINGER PUB LLC

Anul aparitiei: 2013

Master's Thesis from the year 2012 in the subject Economics - Other, grade: 1, VU University Amsterdam, language: English, abstract: One renowned and frequently researched anomaly over the last two decades is the weather effect - the impact of weather on stock market returns. The extensive literature on the weather effect fails to converge towards a unique, systematic and robust relationship between the weather and the stock market. Therefore, the aim of this paper is to explain the contradictory results in the literature by testing whether stock prices are affected by the weather in a significantly different manner depending on the level of market development and explaining how this difference behaves over time. In order to test for this, city-by-city, pooled and binary regressions are employed using data of 10 developed and 10 emerging countries over the period 1996-2011 by using two different means of seasonal adjustment. The results show that weather has a very small impact on the worldwide stock market returns and that the significance of the weather effect is decreasing over time with a cyclical pattern in terms of its recurrence. We identify the year 2001 as the cut-off ...

Michelangelo's Christian Mysticism: Spirituality, Poetry and Art in Sixteenth-Century Italy

Editura: CAMBRIDGE UNIV PR

Anul aparitiei: 2014

In this book, Sarah Rolfe Prodan examines the spiritual poetry of Michelangelo in light of three contexts: the Catholic Reformation movement, Renaissance Augustinianism, and the tradition of Italian religious devotion. Prodan combines a literary, historical, and biographical approach to analyze the mystical constructs and conceits in Michelangelo's poems, thereby deepening our understanding of the artist's spiritual life in the context of Catholic Reform in the mid-sixteenth century. Prodan also demonstrates how Michelangelo's poetry is part of an Augustinian tradition that emphasizes mystical and moral evolution of the self. Examining such elements of early modern devotion as prayer, lauda singing, and the contemplation of religious images, Prodan provides a unique perspective on the subtleties of Michelangelo's approach to life and to art. Throughout, Prodan argues that Michelangelo's art can be more deeply understood when considered together with his poetry, which points to a spirituality that deeply informed all of his production.

Saving My Assassin

Editura: BIBLIOBAZAAR

Anul aparitiei: 2016

"I should be dead. Buried in an unmarked grave in Romania. Obviously, I am not. God had other plans."A must-read for all generations, Saving My Assassin is the unforgettable account of one woman's search for truth, her defiance in the face of evil, and a surprise encounter that proves without a shadow of a doubt that nothing is impossible with God.At just under five feet tall, Virginia Prodan was no match for the towering 6' 10" gun-wielding assassin the Romanian government sent to her office to take her life. It was not the first time her life had been threatened―nor would it be the last.As a young attorney under Nicolae Ceausescu's brutal communist regime, Virginia had spent her entire life searching for the truth. When she finally found it in the pages of the most forbidden book in all of Romania, Virginia accepted the divine call to defend fellow followers of Christ against unjust persecution in an otherwise ungodly land.For this act of treason, she was kidnapped, beaten, tortured, placed under house arrest, and came within seconds of being executed under the orders of Ceausescu himself. How Virginia not only managed to elude her enemies time and again, but how she also ...

Bulk and Boundary Invariants for Complex Topological Insulators: From K-Theory to Physics

Editura: SPRINGER VERLAG GMBH

Anul aparitiei: 2016

This monograph offers an overview of rigorous results on fermionic topological insulators from the complex classes, namely, those without symmetries or with just a chiral symmetry. Particular focus is on the stability of the topological invariants in the presence of strong disorder, on the interplay between the bulk and boundary invariants and on their dependence on magnetic fields.The first part presents motivating examples and the conjectures put forward by the physics community, together with a brief review of the experimental achievements. The second part develops an operator algebraic approach for the study of disordered topological insulators. This leads naturally to the use of analytical tools from K-theory and non-commutative geometry, such as cyclic cohomology, quantized calculus with Fredholm modules and index pairings. New results include a generalized Streda formula and a proof of the delocalized nature of surface states in topological insulators with non-trivial invariants. The concluding chapter connects the invariants to measurable quantities and thus presents a refined physical characterization of the complex topological insulators. This book is intended for ...

A Computational Non-Commutative Geometry Program for Disordered Topological Insulators

Editura: SPRINGER VERLAG GMBH

Anul aparitiei: 2017

This work presents a computational program based on the principles of non-commutative geometry and showcases several applications to topological insulators. Noncommutative geometry has been originally proposed by Jean Bellissard as a theoretical framework for the investigation of homogeneous condensed matter systems. Recently, this approach has been successfully applied to topological insulators, where it facilitated many rigorous results concerning the stability of the topological invariants against disorder.In the first part of the book the notion of a homogeneous material is introduced and the class of disordered crystals defined together with the classification table, which conjectures all topological phases from this class. The manuscript continues with a discussion of electrons' dynamics in disordered crystals and the theory of topological invariants in the presence of strong disorder is briefly reviewed. It is shown how all this can be captured in the language of noncommutative geometry using the concept of non-commutative Brillouin torus, and a list of known formulas for various physical response functions is presented. In the second part, auxiliary algebras are introduced ...
