Pełny tekst źródłaI denna rapport prövas olika viktningsstrategier med målet att prestera bättre i termer av genomsnittlig årlig avkastning, Sharpekvot, aktiv risk, informationskvot och årlig standardavvikelse än det marknadsviktade MSCI USA Index. Rapporten är skriven i samarbete med Öhman och data som används kommer från Bloomberg och består av månadsvis data mellan 1996-2016 av alla aktier som var i MSCI USA Index vid någon tidpunkt mellan 2002-2016. För en given månad används senaste fem åren av historisk data för vår analys. Varje gång som MSCI USA Index ändrar portföljsammansättning så uppdaterar vi vilka värdepapper som ingår i vår portfölj. De traditionella viktningsstrategierna som används i denna avhandling är marknadviktat, likaviktat,risk-justerad alpha viktat, fundamental viktat och minsta varians viktat. De klusterviktade strategierna som används i denna avhandling är konstruerade genom att använda K-medel klustring på aktierna varje månad, tilldela lika vikt till varje kluster och sedan använda traditionella viktningsstrategier inom varje kluster. Dessutom används en GARCH skattad kovariansmatris av klustrena för att bestämma minsta varians optimerade vikter för varje kluster där varje aktie inom alla kluster är likaviktade. Vi konstaterar i detta arbete att den marknadsviktade strategin har lägst avkastning av alla viktningsmetoder. Från resultaten kan vi konstatera att det _nns viktningsmetoder med högre Sharpekvot och lägre standardavvikelse. Risk-justerad alpha viktning använt på traditionellt vis är den strategi som presterar bäst av alla metoder. Alla klusterviktade strategier med undantag av risk-justerad alpha viktning presterar bättre än deras traditionella motsvarighet i termer av avkastning.

This is a critical paper about the incidence of Real State Tax, a municipal tax, in cases where immovable properties and assets held by Federal or States Government are occupied by particular persons, as result of legal use concession contracts or authorized occupation, and its connections with the Mutual Tax Immunity. To achieve these aims, therefore, this study solved the following research problems: in first place, confirmation of the partial unconstitutionality of the National Tax Code in relation to the Constitution of 1946 and its non reception by the current Federal Constitution (1988); construction of the normative matrix rule of the studied tax, since the constitutional level, passing throw the complementary legal settlement, until the local legislation, study that resulted in a doctrinal refinement of the analyzed institute, specially, on its material, personal e quantitative criterions; and, in second place, implications of the Mutual Tax Immunity on the definition of the taxpayer subject, considering the impossibility of transferring the payment responsibility to a non-taxable person, such as the occupant of the public property covered by a concession contract. Furthermore, this research analyzed the Mutual Tax Immunity under the Article 150, VI, ???a???, of the Federal Constitution, in order to identify if it grants a absolute status of protection against the taxation, or if it can be relaxed in cases where the Public Person explore remunerate economic activities. These subjects are under judgment by the Brazilian Supreme Court in the Leading Case number 473 of the general repercussion. Finally, from the theory of the fundamental rights of Robert Alexy, pondering and weighing were developed in order to solve the conflict between the involved constitutional principles: the Free Competition as a key element of an open market economy; and the Mutual Tax Immunity as a guarantor of the Federation Principle.
O objeto de estudo deste trabalho ?? a an??lise da incid??ncia do Imposto Predial e Territorial Urbano (IPTU) sobre os im??veis p??blicos ocupados por particulares por meio de contratos onerosos de concess??o de direito real de uso. No primeiro cap??tulo, a autora fez uma an??lise hist??ria da evolu????o constitucional do estudado imposto e suas rela????es com o C??digo Tribut??rio Nacional (CTN), que resultou no reconhecimento da inconstitucionalidade material de partes dos artigos 32 e 34 do CTN em face da Constitui????o de 1946, bem como a sua n??o recep????o parcial pela Constitui????o Federal de 1988. No cap??tulo subsequente, a norma tribut??ria do IPTU foi estruturada em seus diversos planos normativos, com a constru????o de suas regras-matrizes constitucional, complementar e local, cujos conte??dos se mostraram conflitantes. O terceiro cap??tulo foi direcionado para a constru????o de uma proposta de solu????o para o Tema 437 da Repercuss??o Geral do Supremo Tribunal Federal, que tem como objeto a verifica????o da possibilidade de manuten????o da imunidade tribut??ria rec??proca dos entes p??blicos nas situa????es em que transferem a posse e o uso de seus bens im??veis para particulares mediante o recebimento de contrapresta????o. Nesse contexto, foi necess??rio analisar se a imunidade em quest??o pode ser afastada em raz??o do car??ter oneroso do contrato, bem como se essa atividade de concess??o de bem im??vel p??blico pode ser considerada como h??bil para interferir na livre concorr??ncia do setor imobili??rio local. Para solucionar essas quest??es, utilizou-se a teoria dos direitos fundamentais de Robert Alexy, com a pondera????o e o sopesamento do princ??pio da imunidade tribut??ria rec??proca com o da livre concorr??ncia, a fim de verificar qual deles deve prevalecer no caso concreto. Por fim, foi apresentada uma proposta de solu????o para o leading case que tem a pretens??o tanto de harmonizar o conflito principiol??gico constatado, como de aprimorar a estrutura????o da regra-matriz do IPTU, particularmente no que tange ?? defini????o de seus crit??rios material, pessoal e quantitativo.

Pełny tekst źródłaThree dimensional digitization of built heritage is involved in a wide range of applications (documentation, visualization, etc.), and may take advantage of the diversity of measurement techniques available. In order to improve the completeness as well as the quality of deliverables, more and more digitization projects rely on the combination of data coming from different sensors. To this end, the knowledge of sensor performances along with the quality of the measurements they produce is recommended. Then, different solutions can be investigated to integrate heterogeneous point clouds within a same project, from their registration to the modeling steps. A global approach for the simultaneous registration of multiple point clouds is proposed in this work, where the introduction of individual weights for each dataset is foreseen. Moreover, robust estimators are introduced in the registration framework, in order to deal with potential outliers or measurement noise among the data

802.15.3c is a new indoor wireless communication technique. It operates at the 60Ghz unlicensed band and provides high data rates of more than 1.5 Gbps to satisfy the command of high-speed data transmission such as high definition video stream transmission. There are two transmission modes in 802.15.3c: OFDM mode and SCBT mode. The sampling timing/carrier frequency tracking part of SCBT mode has been designed in this thesis according to the frame format and the characteristics of the channel environment at 60GHz. The main contents in this thesis are carrier frequency offset (CFO) estimation, sampling timing offset estimation and compensation. For CFO estimation, an effective method based on Golay code is proposed to estimate frequency offset. It has low complexity compared to traditional correlation method. In sampling timing and carrier frequency offset tracking problem, unlike conventional tracking method in time domain, here we propose a frequency domain timing offset estimation methods. The proposed methods using the data after equalization and decision to detect their phase difference. By the phase difference, sampling timing and carrier frequency offset could be estimated. The offset estimation is started by using a threshold to select a number of signal samples in frequency domain which have higher SNR than most of received signal samples Second, we use the power of the selected signal samples as a weighting factor to enhance the estimation accuracy. The compensation is done by interpolating the new data sample base on the new sampling time instant. We found out that 8-time interpolation has very good performance by simulation. Here we compare different interpolation structure, including 1, 2 and 3stages design and two design methods: Least square and Equiripple. By adopting these interpolation designs to real tracking application, one can select suitable designs in 15.3c system. With the timing offset estimation method, high-accuracy timing offset can be estimated and compensated so as to maintain the system performance.

Nowadays, digital images are easy to access, and high-resolution images are often required for later image processing and analysis. However, the spatial resolution of images captured by digital cameras is limited by principles of optics and the size of imaging sensors. While constructing optical components that can capture very high-resolution images is prohibitively expensive and impractical, image super-resolution (SR) provides a convenient and economical solution. Image super-resolution aims to generate a high-resolution (HR) image from a low-resolution (LR) input image. It is an essential task in image processing and can be utilized in many high-level computer vision applications, such as video surveillance, medical diagnosis and remote sensing. Super-resolution is an ill-posed problem since multiple HR images could correspond to the same LR image. In this thesis, we propose two algorithms for image super-resolution. The first one is to combine and take advantage of different image super-resolution methods while the second one is based on deep learning. Conventional image super-resolution methods, including bilinear interpolation and cubic convolution interpolation, are intuitive and simple to use. However, they often suffer from artifacts such as blurring and ringing. To deal with this problem, we propose a weighting-based algorithm that takes advantage of three different image super-resolution methods and generates the final results from the combination of these methods. We extract features of the input LR image and investigate the performance of the chosen methods under different features. Results from the candidate methods are combined using a weighted average based on the statistical values of the training data. As the development of convolutional neural networks and deep learning in recent years, models trained on large scale of datasets achieve favorable performance on many computer vision applications. In this thesis, we propose another deep learning-based approach for image super-resolution. We use the wavelet transform to separate the input image into four frequency bands, and train a model for each sub-band. By processing information from different frequency bands via different CNN models, we can extract features more efficiently and learn better LR-to-HR mappings. In addition, we add dense connection to the model to make better use of the internal features in the CNN model. Furthermore, geometric self-ensemble is applied in the testing stage to maximize the potential performance.
