The polarization is the true measure of the degree of ferroelectricity. Generally, ceramic materials with high value of remanent polarization show usable piezoelectric effects. Accordingly, electric poling is one of the crucial intermediate stages of the manufacturing process of the piezoceramics devices. In this thesis, the ferroelectric, pyroelectric and piezoelectric properties and aftereffects in soft and hard PZT are studied. The properti...

In order to achieve interactive rendering of complex models comprising several millions of polygons, the amount of processed data has to be substantially reduced. Two of the most common approaches, orthogonal between each other, to accomplishing this task are: level-of-detail and occlusion culling. This thesis mainly aims at combining these two approaches. A novel error metric is presented which takes visibility information gathered from Hardw...

In the last two decades insulin signalling and protection in brain has emerged as a novel field of research.Although growing evidence supports the hypothesis that dysfunction of neuronal glucose utilization and metabolism and/or in insulin receptor signal transduction cascade is involved in Alzheimer's disease pathogenesis, the role of insulin on oxidative stress- and diabetes-induced neuronal dysfunction and death has been less investigated.T...

The relationship between organisational behaviour research and commercial companies is complex, primarily because academic researchers and companies expect different outcomes from participation in the research. Businesses are usually looking to improve organisational performance and seek immediate, practical and applicable outcomes. Academic researchers seek an extension of theoretical knowledge and a contribution to the advancement of their f...

Seit dem 17. Jahrhundert gibt es Bestrebungenchinesische Klassiker auf christliches oderbiblisches Gedankengut hin zu untersuchen. Damals wares eine spezielle Gruppe der Jesuiten, diesogenannten Figuristen, die eine christlicheInterpretationslinie verfochten. Doch auch in neuererZeit weckt dieses höchst interessante Thema denForschungswillen verschiedenster Menschen. Könntendie alten Chinesen an den biblischen Gott geglaubthaben? Hat dieser si...

This book describes two categories of work, i.e., the finite-difference full-vectorial beam propagation method (FD-FV-BPM) development and microlens design for single-mode fiber (SMF) to laser diode (LD) coupling. Chapter 2 gives a review of the general formula to solve the FV-BPM equation of electric formula by using the FD method. The FD-FV-BPM based eigenmode solver is then successfully employed to investigate the effective index of the fun...

This thesis examines the links developing between the universities and their regions in the globalising knowledge economy as observed in the UK. It examines institutional responses to two realms of policies, namely, higher education policy and regional development policy. The diversifying missions of universities, especially, the 'third stream activities' promoted by the UK government since the late 1990s, are set against the dynamics of the m...

This book evaluates whether Catholics are swing voters, how their voting behavior has changed from 1992 to 2004, and what issues are influencing their voting behavior. Despite much discussion by the U.S. media about the Catholic swing vote, Lori Gula Wright finds that Catholics are not swing voters and that their voting patterns are more similar to the general electorate than ever before. Although religious, class and cultural issues have sig...

Research relating salivary cortisol levels withinternalizing and externalizing behavior problems inyouth has yielded inconsistent results, likely due tothe high day-to-day variation in stress regulation.Understanding stability in this changing system mayrequire an analytical strategy that separatesvariance in cortisol levels attributable to trait- or"basal" versus state- or "situationally-specific"sources. Early morning saliva samples were obt...

This study aimed to investigate how principals in Stockholm as recruiters talked about the recruitment process and ethnic diversity and how these statements could affect the possibilities of a Romany acquiring a Student Aid position within the school in question. The statements are interpreted through a discursive perspective inspired by Foucault and Laclau & Mouffe with a special focus on the power aspect and its consequences in terms of incl...

One of the great challenges facing the international oil and gas industry in the near future is how it will cope with the financial and environmental issues associated with the decommissioning of its oil and gas infrastructures. And in these days where transparency is called for in every aspect of governments' activities relating to their management of public assets this book is perhaps timely in that it addresses the decommissioning problem f...

Although it is widely believed that high quality judgements and operational readiness involve experiential as well as analytical processing, field studies are rare in decision research. A series of empirical studies were therefore directed at studying the underlying affective and cognitive processes in risk, feelings, and operational readiness within a military setting. Three different projects are reported, and altogether 8 different military...

Collisions between a bird and an aircraft, also known as a bird-strike event, are very common and dangerous.In order to predict the damage of the components of a turbine fan blade in a bird-strike, it is necessary to create an appropriate model for the blade and the bird. Several simulations were carried out using the Lagrange equations to simulate this impact. This work presents alternative standard practices for the modeling of bird-strike e...

Every century since the first, the United States has undergone a sometimes violent change in our economic structure. Populations in the U.S. greatly fear a major economic shift. The time has come to change our economic base, and once again, this frightens people. The U.S. has to compete globally to stay economically strong. What do we have to offer the world? Currently, one commodity is found in the degrees in higher education from the U.S. Ju...

Which cost of capital should I use when valuing an investment?" The aim of this book is to provide an answer for corporate finance managers, industrial managers, MBA or finance students who have faced this very dilemma. Finance theory explicitly advocates that firms use a project-specific discount rate when valuing investment projects, or at least a rate specially tailored to each division within a multidivisional firm. Practitioners and schol...

Kommunikation ist ein wesentlicher, immaterieller Erfolgsfaktor für die Führung von Unternehmen. Um den Beitrag dieser zum Unternehmenserfolg anhand von relevanten Steuerungsgrößen messen zu können, wird ein effizientes und effektives Kommunikationsmanagement benötigt, das Intangible Performance Management (IPM). Die Autorin Ariane C. D. Gramm untersucht, wie unter Verwendung einer Portaltechnologie Daten zur Erfolgsmessung erhoben werden könn...

Die vorliegende Arbeit befasst sich mit der selbstregulierenden hydrodynamischen Axiallagerung eines gedeckten Kreiselpumpenlaufrades am Beispiel des Laufrades einer Herzunterstützungspumpe. Die Druckdifferenzen im Radseitenraum zwischen Rotordeckel und Gehäuse regeln die axiale Position des gedeckten Laufrades in Abhängigkeit vom axialen Versatz selbstständig, das heißt ohne Sensoren oder sonstige Regelsysteme. Mit Hilfe geeigneter Experiment...

While a variety of software tools for the recovery of information from formatted, overwritten, or deleted computer hard drives and other magnetic storage media already exist, none of these technologies are capable of recovering information from de-magnetized (aka degaussed) magnetic storage media. The main objective of the research study presented herein was to examine the residual magnetic structures left by a degaussing device (aka degausser...

Das sogenannte soziale Europa zählt zu den größten Herausforderungen der europäischen Integration. Dabei fragt sich, ob es überhaupt ein Europäisches Sozialmodell gibt, und ob die Europäische Union die notwendigen Regelungskompetenzen besitzt. Die vorliegende Arbeit untersucht systematisch den Umfang, die Zielsetzung, die Kompetenzbefugnis und die Erfolgsaussichten eines Europäischen Sozialmodells. Die Autorin definiert einführend die Konture...
