Abstract:

Au cours des dernières années, les réseaux de type (NDN) sont devenus une des architectures réseau les plus prometteuses. Pour être adopté à l'échelle d'Internet, NDN doit résoudre les problèmes inhérents à l'Internet actuel. La fuite d’informations fait partie de ces problèmes, et il est très important d’évaluer ce risque pour les réseaux de type NDN. La thèse se propose d'évaluer ce risque. En supposant (i) qu'un ordinateur appartient au réseau d'une entreprise basée sur une architecture NDN, (ii) que l'ordinateur a déjà été compromis par un support malveillant, et (iii) que la société insta

Abstract:

This Thesis applies complex spatial filters to the front end filtering to a computer vision framework for object recognition and scene categorization. This involves careful filter design in the Fourier domain based on discrete frame properties. Biological plausibility of the suggested filtering is compared against a common model found in the computer vision literature. The designed complex filter bank is equipped with focus-of-attention operators. Specifically, two possible keypoint detection methodologies are examined and compared with state of the art keypoint detection methods. This include

Abstract:

The adaptation of an IIR filter is a very difficult problem due to its non-quadratic performance surface and potential instability. Conventional adaptive IIR algorithms suffer from potential instability problems and a high cost for stability monitoring. Therefore, there is much interest in adaptive IIR filters based on alternative algorithms. Genetic algorithms are a family of search algorithms based on natural selection and genetics. They have been successfully used in many different areas. Genetic algorithms applied to the adaptation of IIR filtering problems are studied in this thesis, and

Abstract:

In digital radio systems, a large number of finite impulse response filters are typically used. Due to their nature of operation, such filters require many multiplication operations, leading to great costs in terms of both chip area and power consumption. For cost reduction reasons, there is a strong business case for implementing these filters without general multipliers so as to reduce the area and power consumption of the overall system.This thesis explores a method of implementing finite impulse response halfband filters without general multipliers, by using a special filter structure and

Abstract:

A digital filter is a system or a device that modifies a signal. This is an essential feature in digital communication. Using optical fibers in the communication has various advantages like higher bandwidth and distance capability over copper wires. However, at high-rate transmission, chromatic dispersion arises as a problem to be relieved in an optical communication system. Therefore, it is necessary to have a filter that compensates chromatic dispersion. In this thesis, we introduce the implementation of a new architecture of the filter and compare it with a previously proposed architecture.

This dissertation presents algorithms for restoring some of the major corruptions observed in archived film or video material. The two principal problems of impulsive distortion (Dirt and Sparkle or Blotches) and noise degradation are considered. There is also an algorithm for suppressing the inter-line jitter common in images decoded from noisy video signals. In the case of noise reduction and Blotch removal the thesis considers image sequences to be three dimensional signals involving evolution of features in time and space.

The use of HVDC has many benefits over HVAC for some specific power transmission purposes. However, two major problems with HVDC links are that the converters produce harmonics and consume reactive power. Electrical filters are used to compensate for this and are a major cost driver of HVDC links. An accurate analysis of the modulation makes it possible to design an optimal filter solution in order to make the link financial viable. This report investigates how the complex cross-modulation phenomenon affects the harmonics. The investigation is limited to line-commutated converter technology (L

Generic visual object tracking is the task of tracking one or several objects in all frames in a video, knowing only the location and size of the target in the initial frame.

Utilizing both spectra can result in a more diverse tracker since visual tracking in infrared imagery makes it possible to detect objects even in poor visibility or in complete darkness. However, infrared imagery lacks the number of details that are present in visual images. A common metho

This type of filter does not exhibit the drawbacks normally associated with its passive counterpart, and a large number of harmonics can be compensated

Abstract:

Šiame darbe yra tiriamos atrankiojo aplinkos 3D geometrijos atstatymo galimybės panaudojant Kinect jutiklio kombinuotą vaizdo-gylio kamerą: pateikiamas matematinis atstatymo modelis, jo parametrizavimui reikalingi koeficientai, apibūdinama tikėtinų paklaidų apimtis, siūloma aktualių scenos duomenų išskyrimo iš scenos procedūra, tiriamas gaunamo modelio triukšmas ir jo pašalinimo galimybės ir metodai. Atstatyta geometrija yra pateikiama metrinėje matų sistemoje, ir kiekvienas 3D scenos taškas papildomai saugo savo spalvinę informaciją. Praktinėje dalyje pateikiama sukurta taikomoji programa yra

Abstract:

Mestrado em Actuarial Science<br>Este trabalho propõe novos métodos para inferir a competitividade das apólices de seguro automóvel quando a informação disponível sobre preços é limitada. Funcionalidades do espaço dos espaços são utilizadas para filtrar o ruído das observações, introduzindo dependências temporais para a transição entre seguradoras ou para conversão. Foram recolhidos dados sobre transições entre companhias de seguros no mercado português para estimar as probabilidades de transição entre seguradoras. O modelo binomial oculto de Markov mostrou-se algo limitado ao pressupor um esp
