Diplomarbeit aus dem Jahr 2009 im Fachbereich Medien / Kommunikation - Multimedia, Internet, neue Technologien, Note: 1,0, FH JOANNEUM Kapfenberg (Fachhochschul-Studiengang Internettechnik und -management), Sprache: Deutsch, Abstract: Web Application Frameworks stellen eine besondere Form der Wiederverwendung von Software dar, die folgende Vorteile bieten kann: Verringerung des Entwicklungsaufwands und -kosten, als auch Erhöhung von Qualität der damit entwickelten Anwendungen. Im ersten Teil dieser Arbeit werden zunächst theoretische Grundlagen für Frameworks und Software-Patterns betrachtet, um die Basis für den zweiten, praktischen Teil - der Evaluierung von MVC-Frameworks für die Erstellung von Webanwendungen in der Skriptsprache PHP zu schaffen. Die Zielsetzung bestand darin, dass am besten geeignete PHP-MVC-Framework für die Internet Solutions Abteilung der MOTIONDATA Software GmbH zu bestimmen. Als Vorgehensweise wurde eine Evaluierung anhand der QSOS-Methode gewählt. Diese iterative Methode besteht aus vier Stufen: (1) Der Definition, (2) der Evaluierung, (3) der Qualifikation und (4) der Auswahl des Frameworks. Es existiert eine Vielzahl an lizenzkostenfreien PHP-MVC-Frameworks, deren gesamte Evaluierung den Rahmen dieser Arbeit sprengen würde, daher wurde eine Vorauswahl mittels einer Analyse des Verbreitungsgrades der Frameworks getroffen. Daraus resultierend wurden CakePHP, Symfony und das Zend Framework für die Evaluierung ausgewählt. Als nächstes wurde ein Kriterienkatalog festgelegt, der aus drei Kategorien besteht: (1) Funktionale Abdeckung, (2) Risiken aus Sicht des Anwenders und aus (3) Sicht des Providers. Auf Basis des Kriterienkatalogs wird die Evaluierung durchgeführt. Danach folgt die Qualifikation durch Gewichtung der Kriterien, um so die Auswahl des geeigneten Frameworks zu ermöglichen.

Master's Thesis from the year 2018 in the subject Business economics - Controlling, grade: 2.0, Berlin School of Economics and Law, language: English, abstract: This thesis aims at elaborating fundamental valuation techniques for crypto assets. Since research in this field is still at the very beginning this work intends to provide investors, financial analysts, token issuers, researchers or crypto enthusiasts a framework of how to determine the fundamental value of this emerging asset class. To do so, three main research questions are formulated: 1. How can the fundamental value of crypto assets be determined? 2. Which valuation techniques can be applied to the different token types? 3. What is the fundamental value of the IOTA token? In order to answer the questions, the thesis will progress in the following manner: First, the reader will be introduced to distributed ledger technology (DLT) and blockchain, which represent the underlying technology of crypto assets. In the next step the term ‘crypto asset’ will be defined. It will be elaborated to what extent crypto assets can be considered as a new asset class and how crypto assets can be classified into different types. The terminological part will end up with a discussion of the fundamental value of this new asset class. The main body of the thesis consists of two parts, a theoretical (conceptual) and a practical (applicational) part. The theoretical part aims to collect and evaluate all current valuation methods for crypto assets. Different absolute as well as relative valuation techniques will be elaborated, namely the Discounted Cash Flow (DCF) model and CAPM, the asset rotation theory, the Equation of Exchange, the NVT ratio, Metcalfe’s Law, the cost of production approach as well as the accessibility discount. The second part of the main body comprises a case application of one valuation model, namely the Equation of Exchange, to the IOTA token.

Inhaltsangabe:Abstract: In today s companies changes happen very fast. On the one hand more and more new technologies are arising, on the other hand business processes have to change because of mergers and acquisitions, new regularities, changing customer requirements and so forth. As business processes are supported by information technology, information technology has to cope with both types of changes. From a business perspective on-demand adaptation of information technology to business is required. Service-oriented architecture (SOA) is currently discussed as an opportunity to better adapt to those changes. According to Gartner's hype cycle for emerging technologies SOA already crossed the peak and is now in the trough of disillusionment. But SOA is far from being unfashionable as it would be expected during this phase. There is still high media coverage and a lot of SOA books have been published recently or will be published during the next months. What is true, however, is that the expectations are getting more realistic and people start to think about the real benefits. This is probably due to the fact that companies experienced, that implementing an SOA is not as fast and easy as the marketing hype might have given the impression. Although the hype surrounding SOA is immense, the concept is still in its early childhood with regards to concrete implementations. According to a survey conducted by Experton Group only three percent of 110 German enterprises, all with over 100 Employees, have a SOA based solution in place. Besides high costs expected from migration to SOA the lack of SOA know-how is identified as a main reason. As the survey reveals 45 percent of the interviewed enterprises have nearly no knowledge or no knowledge about SOA at all. Another 38 percent have only basic knowledge. The lack of knowledge is confirmed by a survey from the research company Quocirca, which found out, based on a sample size of 1500, that 30 percent of respondents have absolutely no knowledge about SOA and 25 percent have only minimal knowledge. Similar results are found among enterprises using SAP software. The results of an online survey conducted by the German speaking SAP User Group (DSAG) shows that 64 percent of 344 enterprises are just a little or not at all familiar with enterprise SOA and only every fifth enterprise has developed a platform strategy. Furthermore, enterprise SOA is still a topic of the IT department, although it would be [...]

Master's Thesis from the year 2017 in the subject Business economics - Investment and Finance, grade: 12/12, Copenhagen Business School (Department of Finance), language: English, abstract: Within this thesis, we develop and apply a comprehensive, yet tractable framework comprising 10 sequential steps for the evaluation of claims on corporations suffering from distress. While traditional industry approaches yield consistent and unbiased valuations for claims on a healthy firm’s assets, we find encumbering evidence that results may be distorted if the valuation object experiences severe financial or economic difficulties. Standard present value, multiple, or accrual based equity valuation methods are deterministic in nature and hence, fail to properly account for the elevated idiosyncratic uncertainties surrounding distress. Initiated by Merton (1974), on the other hand, asset pricing research has suggested structural models as a theoretically superior alternative explicitly incorporating the optionality features and asymmetric payoff-profiles of limited liability claims. However, these models have been rarely adopted by industry professionals for their proclaimed complexity, lack of transparency and stylized assumptions on the valuation object’s capital structure. Accordingly, the proposed framework aims to overcome the above shortcomings of the original Merton (1974) model and eventually allows for an intuitive, seamless pricing of multiple claims with diverse maturity and coupon profiles based on their absolute priority ranking in bankruptcy. First, we provide a thorough characterization of both economic and financial distress and accompanying (firm) characteristics based on which a framework applicability assessment can be performed. Besides, we stress a comprehensive discussion how model input parameters can be estimated reliably. Subsequently, we perform a holistic application of the framework to the distressed German air carrier Air Berlin. Model outputs imply a current market undervaluation of common equity by 52%. While our analysis demonstrates remarkable upsides of the framework compared to traditional valuation procedures, we conclude that a separate estimation of a going concern- and a liquidation value only partially circumvents frictions associated with the computation of a distressed firm’s overall asset value. Moreover, we find that model results are highly sensitive to changes in input factors in general and the expected asset drift rate in particular, implying a considerably low robustness to estimation errors.
