The subject of the thesis is to study the reasons why the GE Money Bank is not the most preferred provider of banking services from the client point of view. In the first part of the thesis, a theoretical basis will be established for the subsequent processing of practical knowledge. The second part is devoted to comparison of the GE Money bank and two other selected banks. The comparison includes areas such as bank product offers, the quality of the services offered on the Internet, Bank Branch and Customer Care Line. Subsequent findings are complemented with the results of marketing research. Finally, recommendations for GE Money Bank are set out, by implementation of those, the bank could become more preferred provider of banking services from the client point of view.

Studien består av en jämförelse av det traditionella arbetssättet,vattenfallsmodellen, och den agila modellen. Studiens fokus ligger påatt undersöka skillnaderna som finns mellan modellerna när detkommer till kravhanteringen och hur man arbetar med att uppfyllakraven. Fokus ligger också på att undersöka varför vissa projektföredrar att arbeta efter vattenfallsmodellen, istället för att använda denagila modellen.Undersökningen består av en litteraturförstudie och semistruktureradeintervjuer med personer som har erfarenhet av båda modellerna.Resultatet av de semistrukturerade intervjuerna sammanställs ochjämförs med resultatet från undersökningen, detta för att kunna besvarafrågeställningarna.Resultatet visar att de skiljer sig markant i kravhanteringen och hur manarbetar med att uppfylla kraven i det olika modellerna.Detta bidrar till att det skiljer sig mycket vilken modell som föredras.Ett exempel som kom fram under intervjuerna är att inom vissa delar avmedicinbranschen så krävs det ett omfattade förarbete då det är olikalagar i olika länder.Det visa sig att statliga och privata verksamheter inte spelar in i valet avmodell utan att det som avgör vilken modell som föredras är vilken typav projekt. Vilken typ av miljö som projektet utförs i spelar också en storroll.Vattenfallsmodellen föredras i projekt som styrs av lagar och regelverkeller om det är väldigt specifika krav. Agila modellen föredras då det ärfriare projekt där lagar och regler inte måste tas i hänsyn på samma sätt. / The study consists of a comparison on the traditional way of working,the waterfall model, and the agile model. The focus of the study is toexamine the differences that exist between the models when it comes torequirements management and how to work to meet the requirements.The focus will also be on examine why some projects prefer to workaccording to the waterfall model, instead of switching to the agilemodel.The survey consists of a literature pre-study and semi-structuredinterviews with people who have experience of both models. The resultsthat where collected from the semi-structured interviews have beencompiled and compared whit the results which were collected from thesurvey in order to be able to answer the questions.The results show that they differ markedly in the requirementsmanagement and how to work with meeting the requirements in thedifferent models. This contributes to the fact that there is a lot ofdifference in which model that is preferred. An example that emergedduring the interviews was that in certain parts of the medical industry,extensive preparatory work is required as there are different laws indifferent countries.It turned out that government and private activities do not play a role inthe choice of model, but that what determines which model is preferredis the type of project. The type of environment in which the projectconsists also plays a major role.The waterfall model will be preferred in projects governed by laws andregulations or if there are very specific requirements. The agile model ispreferred when the projects is freer and where laws and regulations donot have to be taken into account in the same way.

Ziel der vorliegenden Arbeit ist es, die Auswirkungen exogener Schocks auf das Handeln der Unternehmer und die daraus resultierende Entwicklung des Unternehmenserfolges unter Rückgriff auf Modelle der Sozialökonomischen Verhaltensforschung sowie der Industrieökonomik branchenspezifisch zu analysieren. Unter einem exogenen Schock ist dabei eine aus dem System bzw. Modell heraus nicht erklärbare Veränderung der handlungsexogenen Einflußfaktoren der Unternehmen zu verstehen. Aufgrund der Betrachtung von Zeitreiheninnovationen lassen sich diese exogenen Schocks auch als stochastische Prognosefehler der Wirtschaftssubjekte interpretieren. Die Kenntnis der Intensität der Abhängigkeit des Unternehmenserfolges einzelner Branchen von exogenen Schocks ist insbesondere für die Durchführung von Branchenratings von großer Bedeutung. Auf der Basis der gewonnenen Untersuchungsergebnisse können u.a. empirisch fundierte Aussagen über die branchenspezifische Ausprägung zentraler Ratingkriterien getroffen werden, wie beispielsweise über die Konjunkturempfindlichkeit, Fixkostenbelastung, Verhandlungsmacht der Lieferanten, aktuelle Profitabilität, Preisempfindlichkeit sowie das Marktwachstum bestimmter Branchen.

of the paper: Historiography pays different attentions to cadet branches of sovereign dynasties. Because of that some of them are well known to the public, while others are almost forgotten. Generally, they are considered less important. In my work I am paying attention to cadet branches of the Premyslid dynasty and cadet branches of other sovereign dynasties in central Europe. What were their relations with their ruling relatives? What were their marriage policies and their domains? Can we find any general tendencies in cadet branches of sovereign dynasties and were they really less important? I am trying to answer these and other questions in my work. Also, I am trying to introduce life stories of cadet branches. Key words: Middle Ages, cadet branch, Central Europe, Premyslides, Babenberger, Silesian Piasts

This master's thesis describes how to develop loable kernel module for operating system Linux. Module can be use like driver for concrete hardware device. In this case for telecommunication hardware. The second part of this thesis describes how to implement support for this hardware in Asterisk PBX. Support in Asterisk is realized by channel module. In that channel module are implemented functions for process incoming and dialed calls.

Real-time aspects are becoming more important in standard desktop PC environments and x86 based processors are being utilized in embedded systems more often. While these processors were not created for use in hard real time systems, they are fast and inexpensive and can be used if it is possible to determine the worst case execution time. Information on CPU caches (L1, L2) and branch prediction architecture is necessary to simulate best and worst cases in execution timing, but is often not detailed enough and sometimes not published at all. This document describes how the underlying hardware can be analysed to obtain this information.

This thesis deals with the exact solution of large-scale minimum bisection problems via a semidefinite relaxation in a branch-and-cut framework. After reviewing known results on the underlying bisection cut polytope a study of new facet-defining inequalities is presented. They are derived from the known knapsack tree inequalities. We investigate strengthenings based on the new cluster weight polytope and present polynomial separation algorithms for special cases. The dual of the semidefinite relaxation of the minimum bisection problem is tackled in its equivalent form as an eigenvalue optimisation problem with the spectral bundle method. Implementational details regarding primal heuristics, branching rules, so-called support extensions for cutting planes and warm start are presented. We conclude with a computational study in which we show that our approach is competetive to state-of-the-art implementations using linear programming or semidefinite programming relaxations. / Diese Dissertation befasst sich mit der exakten Lösung großer Minimum Bisection Probleme über eine semidefinite Relaxierung in einem Branch-and-Cut Zugang. Nachdem bekannte Resultate zum zugrundeliegenden Bisection Cut Polytop dargestellt wurden, wird eine Studie neuer facettendefinierender Ungleichungen präsentiert. Diese werden von den bekannten Knapsack Tree Ungleichungen abgeleitet. Wir untersuchen Verstärkungen basierend auf dem neuen Cluster Weight Polytop und zeigen polynomiale Separierungsalgorithmen für Spezialfälle. Die Duale der semidefiniten Relaxierung des Minumum Bisection Problems wird in ihrer äquivalenten Form als Eigenwertoptimierungsproblem mit dem Spektralen Bündelverfahren bearbeitet. Details der Implementierung bezüglich primaler Heuristiken, Branchingregeln, sogenannter Supporterweiterungen für die Schnittebenen und Warmstart werden präsentiert. Wir beenden die Arbeit mit einer numerischen Studie, in der wir zeigen, dass unser Zugang konkurrenzfähig zu aktuellen Implementationen basierend auf linearen und semidefiniten Relaxierungen ist.

Context. Theoretical studies predict that the length scale of convection in stellar atmospheres isproportional to the pressure scale height, which implies that giant and supergiant stars should have convection granules of sizes comparable to their radii. Numerical simulations and the observation of anisotropies on stellar discs agree well with this prediction. Aims. To measure the characteristic sizes of convection structures of models simulated with the CO5BOLD code, to look at how they vary between models and to study their limitations due to numerical resolution. Methods. Fourier analyses are performed to frames from the models to achieve spatial spectral power distributions which are averaged over time. The position of the main peak and the averagevalue of the wavevector are taken as indicators of these sizes. The general shape of the intensity map of the disc in the frame is fitted and subtracted so that it does not contaminate the Fourier analysis. Results. A general relationship of the convection granule size being more or less ten times larger than the pressure length scale is found. The expected wavevector value of the time-averaged spectral power distributions is higher than the position of the main peak. Loose increasing trends with the characteristic sizes by the pressure scale height increasing against stellar mass, radius, luminosity,temperature and gravity are found, while a decreasing trends are found with the radius and modelresolution. Bad resolution subtracts signals on the slope at the side of the main peak towards larger wavevector values and in extreme cases it creates spurious signal towards the end of the spectrum due to artifacts appearing on the frames. Conclusions. The wavevector position of the absolute maximum in the time-averaged spectral power distribution is the best measure of the most prominent sizes in the stellar surfaces. The proportionality constant between granule size and pressure length scale is of the same order ofmagnitude as the one in the literature, however, models present sizes larger than the ones expected, likely because the of prominent features do not correspond to convection granules but to larger features hovering above them. Further studies on models with higher resolution will help in drawing more conclusive results. Appendix. The SIA pipeline takes a set of time-dependent pictures of stellar disks and uses a Fourier Analysis to measure the characteristic sizes of their features and other useful quantities, such as standard deviations or the spatial power distributions of features. The main core of the pipeline consists in identifying the stellar disc in the frames and subtracting their signal from the spatial power distributions through a general fit of the disc intensity. To analyze a time sequence, the SIA pipeline requires at least two commands from the user. The first commandorders the SIA pipeline to read the .sav IDL data structure file where the frame sequence is stored and to produce another .sav file with information on the spectral power distributions, the second command orders the reading of such file to produce two more .sav files, one containing time-averaged size measurements and their deviations while the other breaking down time-dependant information and other arrays used for the calculations. The SIA pipeline has been entirely written in Interactive Data Language (IDL). Most of the procedures used here are original from the SIA pipeline, but a small handfull like ima3_distancetransform.pro, power2d1d.pro, extremum.pro and smooth2d.pro from Bernd Freytag and peaks.pro and compile opt.pro amongst others are actually external. / <p>The report consists in two parts:</p><p>1.- The main project, where we apply our pipeline and get scientific results.</p><p>2.- The appendix, where a technical description of the pipeline is given.</p>

Während der Flutkatastrophe im August 2002 wurde auch das Tharandter Badetal durch das Hochwasser der Wilden Weißeritz geflutet. Die dort im so genannten Altbau des Campusgeländes befindliche Zweigbibliothek (ZWB) Forstwesen der Sächsischen Landesbibliothek - Staats- und Universitätsbibliothek Dresden (SLUB) wurde von den Wassermassen, die sich mit 170 Kubikmeter Wasser pro Sekunde den Weg talabwärts suchten, umschlossen und schwer geschädigt.

This masters thesis is focused on the issue of processor architecture. The ground of this project is a design of a simple processor, which is enriched by modern components in processor architecture such as pipelining, cache memory and branch prediction. The processor has been made in VHDL programming language and was simulated in ModelSim simulation tool.
