Full textAn implementation of a subband-based BSS system using DFT filter banks is described, and an adaptive algorithm tailored for subband separation is developed. Aliasing present in the filter bank (due to the non-ideal frequency response of the filters) is reduced by using an oversampled scheme. Experiments, conducted with two-input two-output BSS systems, using both subband and fullband adaptation, indicate that separation and distortion rates are similar for both systems. However, the proposed 32-subband system is approximately 10 times computationally faster than the fullband system.

Full textThe neurotransmitter serotonin controls a great variety of physiological and behavioral processes. In humans, mutations affecting the monoamine oxidase or MAO, the serotonin-degrading enzyme, are highly deleterious. Yet, blind cavefish of the species A. mexicanus carry a partial loss-of-function mutation in MAO (P106L) and seem to thrive in their subterranean environ-ment. This thesis describes the effects of this mutation, from the molecular level to the population level, in order to decipher the exact contribution of mao P106L in the evolution of cavefish neuro-behavioral traits, during their adaptation to the cave environment.In a first paper, we established 4 fish lines, corresponding to the blind cave-dwelling and the sighted river-dwelling morphs of this species, with or without the mutation. We found that mao P106L strongly affected anxiety-like behaviors. Cortisol measurements showed lower basal levels and an increased amplitude of stress response after a change of environment in fish carrying the mutation. Finally, we studied the distribution of the P106L mao allele in wild populations of cave and river A. mexicanus, and discovered that the mutant allele was present – and sometimes fixed - in all populations inhabiting caves of the Sierra de El Abra. The possibility that this partial loss-of-function mao allele evolves under a selective or a genetic drift regime in the particular cave environment is discussed.In a second paper, we assessed the structural and biochemical consequences of the mutation. We found that the reduction of enzymatic activity of mutant MAO is probably caused by a decrease of flexibility in one of the three loops forming the entrance of the active site, thus reducing the access of substrates. HPLC measurements in brains of mutant and non-mutant larvae and adult fish showed major disturbances in serotonin, dopamine and noradrenalin (and metabolites) contents, demonstrating that the P106L mao mutation is fully responsible for monoaminergic disequilibrium in the cavefish brain. We also discovered that the effects of the mutation were partially compensated by a decrease in activity of the TPH, the serotonin biosynthesis rate-limiting enzyme. Our results shade light on the specificities of fish monoaminergic systems.Finally in order to aggravate the MAO inhibition, we generated the first fish knockout MAO mutant. The KO homozygous mutants were stunted and died during the first weeks of development. Contrary to the dopaminergic system which seemed normal in the KO homozygous mutants, the serotonergic system was strongly impaired; no serotonin positive neuron was detected in the hypothalamus

Full textThe equalization of communication channels is addressed by using blind techniques based on higher order statistics. A step-size interval is obtained to ensure the convergence of Steepest-Descent Constant Modulus Algorithm. The Shalvi-Weinstein Algorithm (SWA) and Constant Modulus Algorithm (CMA) are revisited and their tracking capabilities are analyzed by using an energy conservation relation. Moreover, a novel blind algorithm named Accelerated Constant Modulus Algorithm (AC-CMA) is proposed. It adjusts the second derivative (acceleration) of the coefficient estimates and presents a more favorable compromise between computational complexity and convergence rate than CMA or SWA. These results are extended to the MIMO (Multiple-Input Multiple-Output) case. By means of simulations, the algorithms are compared and the convergence and tracking analysis are validated. The Decision Feedback Equalizer (DFE) is considered in the SISO (Single-Input Single-Output) case with the Constant Modulus criterion and a concurrent algorithm is proposed. It avoids degenerated solutions and shows better behavior than the others presented in the literature. In order to avoid error propagation, a hybrid DFE is also proposed. It includes a recurrent neural network in the feedback filter and may be advantageously used to equalize linear and nonlinear channels.

Full textAbstract
When immigrants move to Sweden from their native country it is not unusual that they experience some kind of identity crises. Their own experience of their cultural identity can be very problematic and they often lose a part of what they previously saw as their own identity. To handle such crises the immigrants can use different strategies. They can for example accept their disparity, deny it or emphasize it. The aim of this study is to examine how immigrants in Sweden experience that their cultural identity has changed since they moved here from a country that has a culture that is different from the Swedish culture. To reach my goal with this study I interviewed immigrants/refugees from Chile, Lebanon and Thailand. Some of the results are that my presentation of the problem and the aim with the study were not profound enough. I intended to only write about cultural identity but I came to the conclusion that individual identity and different adaptation strategies were no less important. A further conclusion is that these three ingredients are completely different things; an immigrant can have one individual identity, another cultural identity and use a strategy that does not correspond with any of these. Moreover I also found that a person’s identity does not need to change when moving from their native country to Sweden. Finally I want to stress that my study is not about making sweeping statements, it is rather exemplifying. Identity and strategies are different from one person to another.
Keywords: individual identity, cultural identity, adaptation strategies

systems, mostly due to their welldefined structure and blockwise encoding. Among the main challenges encountered by mobile applications, there is an inherent interblock interference, due to superpositions of delayed signal copies, which is commonly eliminated with the addition of redundancy between adjacent data blocks. In addition to that, channel equalization is also usually employed, in order to further mitigate channel interferences. However, the amount of redundancy may be overestimated, which opens an opportunity for reduced-redundancy superfast transceivers, whose features include high spectral efficiency and low computational cost. Although the superfast approach aims at achieving low complexity, equalizer-coefficient updates are still very complex tasks due to channel variations, and most designs do not employ methodologies for computational-effort reduction. The present work addresses this problem and proposes a new design strategy for block-based transceivers, which provides semiblind equalization with data-selective update, besides the possibility of a generalized approach, based on the fast Fourier transform and diagonal matrices. Simulation results show that our approach updates less than 60% of the equalizer coefficients duringsupervised and blind period and maintain a competitive throughput for single-carrier and multicarrier transmissions.
Atualmente, os transceptores multicanais baseados em blocos são largamente utilizados em sistemas de comunicação sem fio, muito devido a sua estrutura bem definida e ao blockwise encoding. A respeito dos principais problemas encontrados em aplicações móveis, podemos destacar a interferência entre blocos, em decorrência da superposição de cópias atrasadas do sinal, a qual é usualmente eliminada com a adição de uma quantidade de redundância entre blocos de dados adjacentes. Adicionalmente, a equalização é comumente aplicada para mitigar o efeito do canal. Entretanto, a quantidade de redundância pode estar superestimada, abrindo oportunidade para a utilização de transceptores multicanais super-rápidos e com redundância reduzida, que possuem como característica uma alta eficiência espectral e baixa complexidade computacional. Entretanto, a abordagem super-rápida ainda possui uma alta complexidade para atualizar os coeficientes de equalização e a maioria das arquiteturas propostas não utilizam metodologias visando à redução do número de operações. O trabalho atual trata este problema e propõe uma nova arquitetura para tranceptores multicanais com transmissão em blocos, que se utiliza de uma equalização semi-cega com seleção de dados, além da abordagem generalizada, baseadas em transformadas rápidas de Fourier e matrizes diagonais. Os resultados das simulações demonstram que a abordagem permite atualizar menos de 60% dos coeficientes de equalização durante o período supervisionado e não supervisionado de equalização e manter a taxa de saída competitiva para sistemas monoportadora e multiportadora.

Full textThe ultrasonic imaging knows a continuous advance in the aspect of increasing the resolution for helping physicians to better observe and distinguish the examined tissues. There is already a large range of techniques to get the best results. It can be found also hardware or signal processing techniques. This work was focused on the post-processing techniques of blind deconvolution in ultrasound imaging and it was implemented an algorithm that works in the time domain and uses the envelope signal as input information for it. It is a blind deconvolution technique that is able to reconstruct reflectors and eliminate the diffusive speckle noise. The main steps are: the estimation of the point spread function (PSF) in a blind way, the estimation of reflectors using the assumption of sparsity for the examined environment and the reconstruction of the image by reconvolving the sparse tissue with an ideal PSF. The proposed method was tested in comparison with some classical techniques in medical imaging reconstruction using synthetic signals, real ultrasound sequences (1D) and ultrasound images (2D) and also using two types of statistically different images. The method is suitable for images that represent tissue with a reduced amount or average scatters. Also, the technique offers a lower execution time than direct competitors

Full textThe goal of blind image deconvolution is to restore a degraded image without using information from the actual image or from the point spread function. The mapping of the gray levels of an image into a communication signal enables the use of blind equalization techniques for image restoration. In this work, we use a blind image deconvolution scheme based on the convex combination of a blind equalizer with an equalizer in the decision-directed mode. The combination is also blindly adapted, which enables automatic switching between the component filters. Thus, the proposed scheme is able to achieve the performance of a supervised adaptive filtering algorithm without prior knowledge of the original image. The performance of the combination is illustrated by simulations, which show the efficiency of this scheme when compared to other solutions in the literature.
