Este trabalho fornece evidências sobre o papel de ativos e passivos de tributos diferidos como instrumento de tolerância regulatória e arbitragem de capital regulatório por instituições financeiras brasileiras no período de 2004 a 2009. Visando atingir o objetivo da pesquisa, foram desenvolvidas duas hipóteses: a) a tolerância regulatória, visando verificar se os gestores utilizaram tributo diferido para apoiar ou atingir níveis de capital regulatório e quão realistas eram as estimativas sobre a capacidade de realização do tributo diferido, e b) a estratégia de arbitragem de capital regulatório, visando verificar se as escolhas sobre tributos diferidos dos gestores estavam relacionadas com o capital regulatório. Para tanto, este estudo obtêm evidências analisando informações contábeis anuais. As hipóteses são testadas utilizando as técnicas de análise de dados de regressão linear múltipla e regressão com dados em painel. Como resultado, o estudo mostrou que as instituições financeiras brasileiras utilizaram tributo diferido como instrumento de tolerância regulatória. As instituições financeiras não teriam atingido o capital regulatório mínimo sem esses valores. Apesar disso, foram apresentadas evidências de que os gestores foram realistas no reconhecimento de tributo diferido. Também foi mostrado que as decisões dos gestores das instituições financeiras brasileiras estavam orientadas pelo tributo diferido. Conforme apurado, as instituições financeiras com mais fortes posições de capital (maior Nível I) tendem a reportar maior tributo diferido ativo, contrariando a literatura internacional. De maneira geral, revelouse apenas um caso de como a contabilidade pode servir de ferramenta para interferir em questões políticas, econômicas e em setores regulados, buscando atingir fins regulatórios ou cumprir acordos dos quais o país faça parte. / This paper provides evidence on the role of assets and liabilities of deferred taxes as a tool of regulatory forbearance and regulatory capital arbitrage by Brazilian financial institutions in the period 2004 to 2009. In order to achieve the goal of research, two hypotheses were developed: a) the regulatory forbearance in order to verify whether the deferred tax managers used to support or achieve levels of regulatory capital and how the estimates were realistic about the ability to perform the deferred tax, b) the arbitrage strategy of regulatory capital in order to verify that the choices on deferred taxes of managers were related to regulatory capital. Therefore, this study obtained evidence by analyzing annual financial information. The hypotheses are tested using the techniques of data analysis of multiple linear regression and regression with panel data. As a result, the study showed that the Brazilian financial institutions have used deferred tax as a tool of regulatory forbearance. Financial institutions have not reached the minimum regulatory capital without these values. Nevertheless, evidence was presented that the managers were realistic recognition of deferred tax. It was shown that the decisions of the managers of Brazilian financial institutions were guided by deferred tax. As established, the financial institutions with stronger capital positions (higher Tier I) tend to report higher deferred tax asset, contrary to international literature. Overall, it was revealed just a case of how accounting can serve as a tool to interfere in political, economic and regulated industries, seeking to achieve regulatory purposes or to comply with agreements to which the country is part.

Game developers today are putting a lot of effort into their games. Consumers are hard to please and demand a game which can provide both fun and visual quality. This is why developers aim to make the most use of what hardware resources are available to them to achieve the best possible quality of the game. It is easy to use too many performance demanding techniques in a game, making the game unplayable. The hard part is to make the game look good without decreasing the performance. This can be done by using techniques in a smart way to make the graphics as smooth and efficient as they can be without compromising the visual quality. One of these techniques is deferred rendering. The latest version of Microsoft’s graphics platform, DirectX 11, comes with several new features. One of these is the Compute shader which is a feature making it easier to execute general computation on the graphics card. Developers do not need to use DirectX 11 cards to be able to use this feature though. Microsoft has made it available on graphic cards made for DirectX 10 as well. There are however a few differences between the two versions. The focus of this report will be to investigate the possible performance differences between these versions on when using deferred rendering. An application was made supporting both shader model 4 and 5 of the compute shader, to be able to investigate this.

Då scenkomplexitet och ett högre antal ljuskällor blir vanligare inom spel har ett behov av algortimer för att hantera dessa scener, med bra prestanda, uppståt. En allt vanligare algoritm för detta är Deferred Shading. Rapporten utvärderar två olika metoder för Deferred Shading (traditionell Deferred Shading och Light pre-pass rendering).

Deferred shading är en renderingsteknik som har blivit allt mer populär i och med att hårdvaraukraven för tekniken inte längre är ett hinder. Ett problem med deferred shading är fortfarande hur transparenta objekt ska hanteras. Rapporten utvärderar två olika deferred pipelines som hanterar transparent geometri på olika sätt, de två renderingsmetoderna är Inferred Lighting samt Light Pre Pass med framåtrendering för hantering av transparent geometri.

Context. Reaching photo realistic results when rendering 3D graphics in real-time is a hard computational task. Ray-tracing gives results close to this but is too expensive to be run at real-time frame rates. On the other hand rasterized methods such as deferred rendering are able to keep the tight time constraints with the support of modern hardware. Objectives. The basic objective is to merge deferred rendering and ray-tracing into one rasterized pipeline for dynamic scenes. In the thesis the proposed method is explained and compared to the methods it merges. Image quality, execution time and VRAM usage impact are investigated. Methods. The proposed method uses deferred rendering to render the result of the primary rays. Some pixels are marked, based on material properties for further rendering with ray-tracing. Only reflections are presented in the thesis but it has been proven that other global illumination effects can be implemented in the ray-tracing framework used. Results and Conclusions. The hybrid method is proved through experiments to be between 2.49 to 4.19 times faster than pure ray-tracing in the proposed pipeline. For smaller scenes it can be run at frame rates close to real-time, but, for larger scenes such as the Crytek Sponza scene the real-time feeling is lost. However, interactivity is never lost. It is also proved that a simple adjustment to the original framework can save almost 2/3 of the memory spent on A-buffers. Image comparisons prove that the technique can compete with offline ray tracers in terms of image quality.

Against the background of increasing tension between the need for additional disclosure and an information overload in financial statements, this study investigates the relevance of specific tax accounting information in an experimental setting. Participants make judgments on the financial performance, investment attractiveness and tax position of the firm, in absence or in presence of detailed tax information in the other comprehensive income statement. Our results do not support the notion that such deferred tax information has an effect on the judgment of experts, as long as the amounts of deferred tax are normal. However, when the detailed amounts of deferred tax are abnormally high, judgment differs significantly. Our result is important for standard setters, as they may consider further developing guidance in standards (such as IAS 1 and IAS 12) and in the Practice Statement for how to judge materiality of information, in accordance with the materiality principle set forth in IAS 1.31. By doing so, the risk of information overload can be reduced. Our study thus contributes to the current debate on the extent of disclosure. Our results are novel and the method used allows for the isolation of effects and the identification of causal relationships. / Series: WU International Taxation Research Paper Series

The goal is to become familiar with deferred tax concept - explain the nature and bring this accounting term near on a few selected areas. The thesis deals with two different accounting frameworks, Czech legislation and transnational concept in form of International Financial Reporting Standards with the motive to try to explain true nature of deferred tax and to conclude which of the accounting system sufficiently regulates this area so, that it could reflect all important differences with tax system and leads to fair distribution of profits among owners. In other words, not to awarded disposable earnings to those who do not belong solely because of differences between taxes and accounting. Thus, in a situation where these differences did not exist, the belonging amount of allocation of the profit would be else. The thesis is complemented with descriptive examples and illustrations created from real financial statements of two chosen companies. Representative of the Czech framework is Skanska a.s., and for a framework of IFRS the company Unipetrol a.s. The thesis concludes that a more elaborate treatment of deferred tax includes International Financial Reporting Standards, and therefore the financial statements prepared under them provide truer view of an analyzed company to user.

The topic of this thesis is the principle of prudence. The chapters are devoted to the tools (impairment, provisions, depreciation, deferred tax). The thesis is focused on Czech legislation, but it also contains the basic view of International Financial Reporting Standards.

The thesis is focuses on the principle of prudence. Describes in detail the tax and accounting point of view of its instruments. The first chapter is devoted to generally accepted accounting principles and their description. Other chapters have directly target specific tools. At the end of each chapter, which is devoted to the tools of the precautionary principle, are indicative examples.

While real-time applications are nowadays routinely used in visualizing large nu- merical simulations and volumes, handling these large-scale datasets requires high-end graphics clusters or supercomputers to process and visualize them. However, not all users have access to powerful clusters. Therefore, it is challenging to come up with a visualization approach that provides insight to large-scale datasets on a single com- puter. Explorable images (EI) is one of the methods that allows users to handle large data on a single workstation. Although it is a view-dependent method, it combines both exploration and modification of visual aspects without re-accessing the original huge data. In this thesis, we propose a novel image-based method that applies the concept of EI in visualizing large flow-field pathlines data. The goal of our work is to provide an optimized image-based method, which scales well with the dataset size. Our approach is based on constructing a per-pixel linked list data structure in which each pixel contains a list of pathlines segments. With this view-dependent method it is possible to filter, color-code and explore large-scale flow data in real-time. In addition, optimization techniques such as early-ray termination and deferred shading are applied, which further improves the performance and scalability of our approach.
