Full textSensory perception is not purely a bottom-up process determined only by sensory stimuli, but is strongly dependent on top-down factors such as attention or expectations.Which neuronal mechanisms underlie the integration of bottom-up and top-down directed processing of sensory information? In the first part of this study this question was addressed by numerical simulations of a neural network model of two simplified cortical areas. The simulated network takes into account recent findings concerning the pronounced functional asymmetry of cortical neurons.The network replicates several important neurophysiological findings: 1) Top-down signals enhance firing rates in hierarchically high and low cortical areas. 2) The processing of two competing stimuli is biased towards one stimulus by selective top-down signals. 3) The reciprocal network architecture results in a bidirectional flow of information. Together with the implemented non-linear somato-dendritic interaction this leads to neuronal bursting behaviour with a high signal to noise ratio. The simulated network demonstrates the critical role of the complex non-linear properties of cortical neurons for the integration of bottom-up and top-down directed sensory processing. The central question of the second part of this study is the functional role of high-frequency synchronization of neuronal activity. The strong interest in the temporal dynamics of neuronal activity is particularly due to the hypothesis of a “synchronization-code” according to which information is not solely encoded by firing rates but also by the synchronization of neuronal ensembles. Is such synchronization observed in awake animals behaving under natural conditions? Are these synchronizations stimulus selective? Is it possible to define a functional frequency band of synchronization based on an objective criterion? These questions were addressed by chronic extracellular recordings of neuronal activity in primary visual cortex of awake behaving cats: 1) Visual stimulation induces neuronal synchronization in a broad and high frequency range. 2) This synchronization is selective for the orientation of a visual stimulus. 3) By analyzing the stimulus selectivity of synchronization a functional band of neuronal synchronization can be defined from about 45 to 120 Hz. These results from animals behaving under natural conditions show a surprisingly broad spectral distribution of synchronization that extends well beyond typically investigated frequency ranges. These results cast doubt on the hypothesis of cortical high-frequency synchronizations as a spectrally sharp and static phenomenon.

In this thesis I present a framework for integrating bottom-up and top-down computer vision algorithms. I developed this framework, which I call the Map-Dictionary Pixel framework, because my intuition is that there is a need for tools that make it easier to build computer vision systems that mimic the way human visual systems process information. In particular, we humans humans create models of objects around us, and we use these models, top-down, to interpret, analyze and discern objects in the information that comes bottom-up from the visual world. After introducing my Map-Dictionary Pixel framework, I demonstrate how it empowers computer vision algorithms. I implement two different systems that extract the pixels of the image that correspond to a human. Even though each system uses different sets of algorithms, both use Map-Dictionary Pixel framework as the connecting pipeline. The two implementations demonstrate the utility of the Map-Dictionary Pixel framework and provide an example of how it can be used.

Full textLiterature has long investigated the contributions of top-down and bottom-up processes in guiding search behavior. Recent findings suggest a modulatory role of top-down processes on attentional capture. However, results are contradictory, and whether and how top-down processes intervene has not been clearly established yet. Here, we approached the issue from the perspective of proactive top-down processes of distractor expectation and leveraged the Distractor Context Manipulation (DCM) paradigm to help characterizing their recruitment in visual search. Thus, we combined a feature search (i.e., search for a high-contrast target among no-contrast distractors) and a conjunction search (i.e., search for a high-contrast target among high-contrast distractors) with the DCM paradigm (Exp 1-4). Accordingly, blocks of trials were of three types: a Pure block containing no distractor-present trials, and two blocks containing frequent distractor-present trials (i.e., Mixed Feature and Mixed Conjunction). Subjects were instructed to look for the target on each trial. The comparison of distractor-absent trials of Mixed vs Pure blocks allowed detecting proactive top-down processes of distractor expectation. First, we investigated whether proactive top-down processes were recruited in distracting contexts of visual search and whether their potential recruitment was modulated by the type of search (Exp 1). Results attested for a proactive recruitment of top-down processes of distractor expectation in both feature and conjunction search. Such recruitment entailed a response time (RT) cost as well as a beneficial enhancement of the detection sensitivity (d’) to the target when distractors were expected, yet not presented. Overlapping results emerged in covert (Exp 1, 3) and overt (Exp 2, 4) variants of visual search. Since previous distracting experience shaped distractor expectation, we, also, sought to disentangle the role of expectation and experience in the activation of top-down processes. Results (Exp 2, 4) showed that the distractor expectation cost occurred regardless of whether or not distractors occurred in the immediately preceding trial. However, the magnitude of the cost was larger after distracting trials suggesting that these processes do not rely only on tonic expectation-based mechanisms but they are also contingently reinstated after a distracting experience occurred. Experiment 3 tried to characterize the implicit vs explicit nature of top-down mechanisms triggered by distracting experience. Results showed that RT-costs and d'-benefits did not change when distraction occurrence was unpredictable and when it was predictable. Therefore, top-down control setting triggered by recent distracting experience seems to be not subjected to explicit control. Experiment 4 further investigated the role of experience and expectations in order to disentangle their relative contributions. Here, also another type of top-down expectation was manipulated: the temporal certainty of incoming potentially distracting event. Results indicated a preponderant role of top-down expectations by showing that RT-costs followed the time course of temporal expectation of incoming potentially distracting events while temporal recency from a previous distracting experience had a smaller weight. Finally, Experiment 4 explored the EEG correlates of distractor expectation. An enhancement of the occipital P1 amplitude was elicited by both search and neutral stimuli but only when a temporal expectation of a potentially distracting event was induced indicating that distractor expectation modulates visual attentional processes in lower sensory areas. Overall, results suggested that in both feature and conjunction search preparatory top-down processes are proactively enrolled to face with expected task demands based on previous distracting experiences. These results help characterizing how top-down mechanisms intervene in different types of visual search.

Full textIncludes bibliographical references (p. 69-70).
Many recognizers use bottom-up methods for recognizing each phoneme or feature, and use the cues and the context to find the most appropriate words or sentences. But humans recognize words not just through bottom-up processing, but also top-down. In many cases of listening, one can usually predict what will come based on the preceding context, or one can determine what has been pronounced by listening to the following sounds. Therefore, if some cues to a word are given, it would be possible to refine the recognition by using the top-down method. This thesis deals with the improvement of the performance of recognition by using the top-down method. And most of the work will be concentrated on the problem of vowel recognition, when the adjacent consonants are known.

The embedded systems are present in every aspect of life. They are available in watches, mobile phones, tablets, servers, health aids, home security, and other everyday useful technology. To meet the demand for powering up a rising number of embedded devices, energy harvesters emerged as a solution to provide an autonomous solution to power on low-power devices. With energy autonomy, came energy scarcity that introduced intermittent computing, where embedded systems operate intermittently because of lack of constant input power. The intermittent systems store snapshots of their progress as checkpoints in non-volatile memory and restore the checkpoints to resume progress. On the whole, the intermittent system is an emerging area of research that is being deployed in critical locations such as bridge health monitoring. This research is focused on securing intermittent systems comprehensively. We perform a top-down analysis to identify threats, mitigate them, optimize the mitigation techniques, and evaluate the implementation to arrive at secure intermittent systems. We identify security vulnerabilities that arise from checkpoints to demonstrate the weakness in intermittent systems. To mitigate the identified vulnerabilities, we propose secure intermittent solutions to protect intermittent systems using a generic protocol. Based on the implementation of the generic protocol and its performance, we propose several optimizations based on the needs of the application to securing intermittent systems. And finally, we benchmark the security properties using two-way relation between security and application in intermittent systems. With this research, we create a foundation for designing secure intermittent systems.

Full textDeux voies de fabrication sont envisagées : la lithographie par AFM (Microscope à Force Atomique) et la lithographie électronique. Cette dernière étant plus reproductible, les dispositifs finaux sont fabriqués par cette technique, à partir d'un substrat SOI et plusieurs étapes de gravure et métallisation.
L'étude des nanofils par mesures I(V) nous permet de mettre en évidence une zone déplétée à l'interface Si/SiO2 natif. Grâce à l'utilisation de nanofils de largeurs et de longueurs différentes, nous sommes capables de déterminer la largeur de la zone déplétée, la densité d'états d'interface ainsi que le niveau de dopage des nanofils. L'évolution de la résistance des nanofils avec la température est également étudiée et montre une dépendance associée à la diffusion des phonons de surface.
Trois applications sont ensuite décrites : un décodeur, un commutateur de courant et un capteur biologique. En effet, la gravure locale des nanofils conduit à une modulation de la bande de conduction, rendant possible la réalisation d'un décodeur. D'autre part, la fabrication de croix à base de nanofils et de grilles latérales à proximité des croix qui contrôlent le passage du courant dans les différentes branches permet de former un commutateur de courant. Enfin, grâce au rapport important de la surface par rapport au volume des nanofils et leur bonne fonctionnalisation chimique, ceux-ci sont utilisés pour détecter électriquement des interactions biologiques (détection de l'ovalbumine).

Full textAlso presented are the issues behind the design of an audio-band, single bit switched capacitor delta-sigma modulator with 16 bits of performance. This begins with the filtering function design, continues with the realization in a low voltage standard CMOS process, and concludes with experimental measurements to gauge performance. The creation of the modulator was carried out using the proposed top-down design methodology, and its experimental performance is used to help validate the procedure.
In addition, the design and fabrication of a multibit DeltaSigma modulator including a novel internal DAC was carried out. The multibit DAC is based on encoding DC levels into digital PDM bitstreams, which are then decoded by a single analog filter. The use of a single filtering path reduces mismatch effects in the DAC. The functionality, performance, and limitations are explored by examining the experimental results of a 2.5 V, audio-band, 2nd order, 3-bit DeltaSigma modulator in a 0.25 mum CMOS process.

Distractibility and impulsivity have long been thought of as two separate psychological processes; however, there is currently evidence that suggests otherwise. The aim of this study was to gain a better understanding on the behavioral level of the interaction between these two traits. I proposed a model in which some individuals have a higher than average threshold for activation of the top-down cognitive control resources that are important for directing and maintaining attention as well as for regulating impulsive behaviors. To test the strength of this model I used an experimental paradigm that combined two different types of tasks—a spatial working memory task and a delay discounting of a primary reward (juice) task. Participants were administered the Conners’ Adult ADHD Rating Scale in order to be classified in terms of their trait distractibility and trait impulsivity subscale scores. The results suggest that there is indeed an association between the traits of distractibility and impulsivity, and that they may be linked by a common mechanism involving a variable threshold of activation of top-down control resources to regulate these behaviors

Full textThis work focuses on the study of silicon nanowires made by a top-down approach. The context of the study is the miniaturisation of the components and the understanding of the transport in 1D systems. Two fabrication approaches are studied : AFM lithography (Atomic Force Microscope) and e-beam lithography. The latter being more reproducible, the final devices are fabricated by this technique using a SOI substrate and multiple steps of etching and metallization.Transport characterization of the Si nanowires allows us to highlight a depleted area at the interface Si/native SiO2. Using nanowires with different widths and lengths, we can determine the depletion width, the surface state density as well as the doping level of the nanowires. The evolution of the nanowires resistance with temperature is also investigated, showing a dependence associated with surface phonons scattering. In the last chapter, three applications are described : a decoder, a current switch and a biosensor. The use of a local etching allows the modulation of the conduction band of the nanowires, opening the way to build a decoder using two local gates. Crossbar structures, where lateral gates which can derive the current in the di_erent branches, lead to the fabrication of a current switch. Finally, thanks to the large surface to volume ratio in these structures, the nanowires are used to detect electrically the interactions between molecules (ovalbumine detection)

Full textThere is two ways to understand goodwill. Number one, internally generated goodwill and number two, acquired purchase goodwill. The main topic for this research is acquired purchase goodwill. Many people believe that goodwill is a sort of black box. It is unclear what goodwill actually is. There is no limit on how you can define acquired purchase goodwill. In academia we talk about two perspectives, top-down perspective and bottom-up perspective. The first perspective sees goodwill as a residual and the second perspective sees goodwill as a sum of its components. When you put on these two glasses, the idea is that you may be able to see how businesses account for their goodwill. It is easier said than done, many times theory and practice does not get along. There is a big space between the theories on how you work with goodwill in the reality. Only a few have studied the definition of goodwill. Because of that we really wanted to investigate this phenomenon. We have analyzed if the gap between theory and reality has been reduced. The purpose of this study is to investigate if the staffing companies define goodwill different in their annual reports. The tool we have used is to interview professional accountants to get their opinion. The conclusion is that the annual report is quite standardized which means it is difficult to understand what goodwill actually is. Everybody we interviewed have the same opinion, that goodwill is a residual. They made no reflections or additions on that subject. In summary, we know now that after our study, no big change has been made between theory and practice.

Està esbiaixada per regions cerebrals d’ordre superior que anticipen estímuls rellevants per a la tasca i augmenten la sensibilitat neuronal a l’escorça sensorial. Sovint, es creu que això es produeix mitjançant l'excitació de neurones seleccionades, però alguns estudis han suggerit que no és la descripció completa del procés. Cada vegada més, l’evidència apunta cap a un mecanisme alternatiu de polarització inhibitiva de dalt a baix. Aquí hem investigat, aleshores, un model d’atenció inhibitori. Primer, vam demostrar com es redueix la sensibilitat a les funcions d’estímul irrellevants per tasques mitjançant la supressió de dalt a baix. En segon lloc, vam demostrar la capacitat d’un model d’espiga basat en la biologia per modular el processament de la informació i l’hem comparat amb la fisiologia. Per últim, hem explorat la interacció entre els models excitadors i inhibidors d’atenció de dalt a baix en un agent de cerca d’aliments. Els nostres resultats donen suport al model inhibitori de l’atenció de dalt a baix com a mecanisme d’atenció biològica i mostren com s’adapta al ‘zeitgeist’ actual dels mecanismes d’atenció de dalt a baix.
