Full textAbstract:
The detection of visual stimuli involves neurons which are selectively responsive to components of a visual scene. In the early stages of visual processing, it is commonly accepted that neurons respond to the changes in luminance associated with objects and object boundaries. However, recent experiments have demonstrated that some neurons can also respond to features which are not defined by luminance variations. These features are termed "second-order" because they require more complex processing, and neurons which respond to second-order features are necessarily nonlinear.In this thesis, I undertook a three dimensional physiological characterization (i.e. tuning of orientation, spatial frequency and temporal frequency) of such nonlinear neurons in order to shed light on their processing capabilities. In particular we sought to address the following issues: (1) whether the temporal and spatial properties underlying second-order motion are similar to those underlying luminance based ("first-order") motion; (2) whether these properties remain constant using different types of second-order stimuli, suggesting that neurons' responses are invariant to the physical attributes comprising the stimulus; and (3) whether second-order processing is a cortical mechanism or can occur at an earlier stage of the visual system (e.g. in the lateral geniculate nucleus). Taken together these results have a dual function; they provide insight into the complex cellular processing of higher order features, and they provide a general framework for the generation of second-order models.

Full textAbstract:
We study mobile systems, i.e. systems with a dynamically changing communication topology, from a process algebras point of view. Mobility can be introduced in process algebras by allowing names or terms to be transmitted. We distinguish these two approaches as first-order and higher-order. The major target of the thesis is the comparison between them. The prototypical calculus in the first-order paradigm is the π-calculus. By generalising its sort discipline we derive an w-order extension called Higher-Order π-calculus (HOπ). We show that such an extension does not add expressiveness to the π-calculus: Higher-order processes can be faithfully compiled down to first-order, and respecting the behavioural equivalence we adopted in the calculi. Such an equivalence is based on the notion of bisimulation, a fundamental concept of process algebras. Unfortunately, the standard definition of bisimulation is unsatisfactory in a higher-order calculus because it is over-discriminating. To overcome the problem, we propose barbed bisimulation. Its advantage is that it can be defined uniformly in different calculi because it only requires that the calculus possesses an interaction or reduction relation. As a test for barbed bisimulation, we show that in CCS and π-calculus, it allows us to recover the familiar bisimulation-based equivalences. We also give simpler characterisations of the equivalences utilised in HOπ. For this we exploit a special kind of agents called triggers, with which it is possible to reason fairly efficiently in a higher-order calculus notwithstanding the complexity of its transitions. Finally, we use the compilation from HOπ to π-calculus to investigate Milner's

Due to the rapid changing environment many organizations are striving to achieve agility and flexibility in internal and external environments. In order for an enterprise to be able to respond to this changing environment, it must integrate the business functions into a distinct system that is capable of exploiting information technology competently. Enterprise Resource Planning (ERP) mainly focused on integrating internal business functions and implementing an ERP system requires a significant amount of time and financial resources. Moreover, ERP systems are complex, non-flexible and are not capable of collaborating with autonomous application leading to difficulty in integration and customization [3]. Enterprise Application Integration (EAI) is an alternate technology to ERP where the integration process is automated without much effort. This research work mainly focuses on designing an order processing system using the concepts of EAI for Intra Organization in any small and medium enterprises (SME’s). As a result of this research work, a five layered architecture has been designed which can be integrated in any enterprise without affecting the existing business workflow. This architecture is categorized into Data Layer, Middleware Layer, Event Generation Layer, Translation Layer and Interface layer. Further to actually test the extent and reliability of this architecture a prototype system implementation is built at Hyundai Mobis Parts- Sweden, using the concepts of EAI. In addition the evaluation of the prototype system is performed to check the above defined layers of the architecture.

Aqueta tesi tracta dues aplicacions dels estadístics d'ordre superior al tractament d'imatges.En primer lloc, es proposa l'ús de mètodes basats en estadístics d'ordre superior per a larestauració d'imatges. Primerament, es consideren imatges degradades per filtres de blurringde fase lineal o zero i soroll Gaussià aditiu. S'examina un segon model de degradació perimatges astronòmiques on el blurring es causat per les turbulències de l'atmosfera i lesaberracions del telescopi. L'estratègia de restauració en amdós casos es basa en el fet de que lafase del senyal original i la dels seus estadístics d'ordre superior no es ditorsionen per lafunció de blurring. Les dificultats associades a combinar senyals de dues dimensions i elsseus estadístics d'ordre superior, es redueixen gràcies a la utilització de la transformada deRadon. La projecció a cada angle de la imatge de dues dimensions és un senyal d'unadimensió que pot ser processada per qualsevol mètode de reconstrucció d'una dimensió. Enaquesta part de la tesi es desenvolupen mètodes que utilitzen el Bicepstrum IterativeReconstruction Algorithm i el Weight Slice Algorithm. Un cop es reconstrueixen lesprojeccions originals, la transformada inversa de Radon ens dóna la imatge restaurada.En la segona part de la tesi es proposa una classe de funcions de cost, basades novament enestadístics d'ordre superior, per estimar el vector de moviment entre imatges consecutivesd'una seqüència. En cas de que les imatges estiguin degradades per soroll Gaussià aditiu decovariancia desconeguda, la utilització d'estadístics d'ordre superior és molt apropiada ja queels cumulants de processos Gaussians són nuls. Per a obtenir estimacions consistents esnecessiten varies realitzacions de la mateixa seqüència, cosa que generalment no és possible.Tanmateix, imatges prèvies de la seqüència on el problema d'estimació del moviment ja s'haresolt, poden ser utilitzades per a obtenir estimacions assimptòticament no esbiaixades. Aixòes possible quan es pot suposar estacionaritat entre les imatges de la seqüència empreades.L'objectiu d'aquesta part del treball d'investigació es l'ús de tècniques basades en estadísticsd'ordre superior que puguin estimar moviment fins i tot per a regions o blocs relativamentpetits. Es defineix també una estimació alternativa quan només es disposa de dues imatges,que supera altres tècniques existents. Finalment es desenvolupa una versió recursiva per casosen què es tingui accés a informació a priori.

Full textAbstract:
In a general study of the literature eleven main areas of research were considered relevant to workflow management and its application in the domain of Sales Order Processing (SOP). It was concluded that exception handling may provide a unifying focus on the dynamic behaviour of workflow systems. Indeed this initial study revealed that current workflow approaches: (1) will overly constrain sales order processors as they seek to handle exceptions by imposing unrealistic and thus rigid ways of working onto their end-users; (2) do not support the needs of workflow system developers very well, since their workflow specifications are time-consuming to develop and maintain and are difficult to verify. Having made these observations this study conducted a detailed literature study and identified three main classes of workflow approaches, namely: traditional workflow approaches (i.e. SADT/IDEF0, Grai Nets, IDEF3, IEM and ClMOSA), ECA workflow approaches (i.e. WIDE and Rapide) and transactional workflow approaches (i.e. Sagas, ConTracts, and Partial Rollbacks). Subsequently it was decided to study specific properties of sales order processing exceptions and their effects.

Inefficiencies in a warehouse that operates multiple zones can create bottlenecks in the order fulfillment process. This study’s focuses on the exploration of potential bottlenecks in an agricultural aftermarket company’s order fulfillment process and its multi-zone warehouse. Order fulfillment includes stages of order processing, SKU picking and staging from the conveyor zone and the “H” zone, and the final packaging and shipping of the order within the Truck Freight Department. A review of the company’s EOP program, and the effects of the program, provides additional insight into our understanding of bottlenecks within a dynamic the system. In doing so, the research will extend the existing knowledge on warehouse management with multiple zones. The conclusion of this paper offers solutions that will alleviate the bottlenecks and improve the overall efficiency of the order fulfillment process within a multi-zone warehouse.

Full textAbstract:
Intrinsically conducting polymers (ICPs) with high mechanical strength and electrical conductivity are attractive for several applications spanning the fields of energy, defense, and transportation. Electrochemically processed polythiophene (PTh) films are a class of ICPs that have been demonstrated recently to possess electrical conductivities as high as 1,300 S/cm and be stronger than common types of processed aluminum foils. While these results are promising, the electrical conductivity of PTh is still low compared to metals and the effects of important process conditions such as electrode resistance, distance between working and counter electrodes, and thiophene concentration on the structure and physical properties of electrochemically processed PTh films must be investigated in detail. In this work, electrode resistance and inter-electrode distance were demonstrated to be inversely proportional to the charge efficiency for PTh film growth. A critical concentration of thiophene that produced films with the highest conductivity was also revealed. Anionic surfactants sodium dodecyl sulfate (SDS) and sodium dodeclybenzene sulfonate (SDBS) were used, with and without a proton scavenger, in the Lewis acid boron trifluoride diethyl etherate (BFEE) electrolyte, which allows polymerization of thiophene at low oxidation potentials, to enhance the ordering and conjugation length of PTh through stabilization of the radical cation of thiophene via the dodecyl chain of the anionic surfactants. X-ray diffraction spectra revealed enhanced order and packing when surfactant was used during the processing of PTh films, and measured electrical conductivities were increased by as much as 300% because of the surfactant-mediated structural improvements. Necking behavior observed in tensile test of PTh films with anionic surfactant additives also suggests chain alignment and increased chain length.

Full textAbstract:
In this thesis, advanced robust estimation methodologies for signal processing are developed and analyzed. The developed methodologies solve problems concerning multi-sensor data, robust model selection as well as robustness for dependent data. The work has been applied to solve practical signal processing problems in different areas of biomedical and array signal processing.
In particular, for univariate independent data, a robust criterion is presented to select the model order with an application to corneal-height data modeling. The proposed criterion overcomes some limitations of existing robust criteria. For real-world data, it selects the radial model order of the Zernike polynomial of the corneal topography map in accordance with clinical expectations, even if the measurement conditions for the videokeratoscopy, which is the state-of-the-art method to collect corneal-height data, are poor.
For multi-sensor data, robust model order selection selection criteria are proposed and applied to the problem of estimating the number of sources impinging onto a sensor array. The developed criteria are based on a robust and efficient estimator of the covariance of the r-mode unfoldings of a complex valued data tensor. Both in the case of Gaussian noise and for a brief sensor failure, the proposed robust multi-dimensional schemes outperform their matrix computation based counterparts.
In the context of robustness for multi-sensor data, we next investigate the problem of estimating the complex-valued amplitude of sinusoidal signals in a completely unknown heavy-tailed symmetric spatially and temporally independent and identically distributed (i.i.d.) sensor noise environment. A selection of non-robust and robust estimators are compared to a proposed semi-parametric robust estimator.
A third research focus in the area of multi-sensor data is that of analyzing the robustness of spatial time-frequency distribution (STFD) estimators. We provide a robustness analysis framework that is based on the influence function. The influence function is a robustness measure that describes the bias impact of an infinitesimal contamination at an arbitrary point on the estimator, standardized by the fraction of contamination. In addition to the asymptotic analysis, we also give a definition of the finite sample counterpart of the influence function. Simulation results for the finite sample influence function confirm the analytical results and show the insensitivity to small departures in the distributional assumptions for some recently proposed robust STFD estimators.
A large part of this thesis concerns the topic of obtaining and analyzing robust estimators in the dependent data setup. First, some practical issues concerning the detection, and robust estimation in presence of patient motion induced artifacts in biomedical measurements are addressed. In particular, we provide an artifact-cleaning algorithm for data collected with an electrocardiogram (ECG). This is especially important for the monitoring of patients with portable ECG recording devices, since these devices suffer severely from patient motion induced artifacts. A second real-world problem addressed in this doctoral project is that of forecasting the intracranial pressure (ICP) levels for patients who suffered a traumatic brain injury. This enables active and early interventions for more effective control of ICP levels. We propose a methodology which uses combined artifact detection and robust estimation after a data transformation into the empirical mode domain.
Motivated by plethora of practical applications, we then focus on deriving and analyzing sophisticated robust estimation and model selection techniques for autoregressive moving-average (ARMA) models. A fast algorithm as well as a detailed statistical and robustness analysis of a novel robust and efficient estimator is given. For the proposed estimator, which is termed the bounded influence propagation (BIP) τ-estimator, we compute a complete statistical robustness analysis, which includes conditions for the consistency, as well as a proof of qualitative and quantitative robustness. The robustness is measured by means of the influence function, the maximum bias curve and the breakdown point. The fast algorithm of the proposed estimator is based on first computing a robust initial estimate of an autoregressive (AR) approximation from which the ARMA model parameters are derived. In this way, the ARMA model parameters are derived from the long AR approximation without further use of the outlier-contaminated observations. The estimator is very suitable and attractive for ARMA model selection purposes, since the computational cost of estimating all the candidate ARMA models approximately reduces to that of computing one long AR model. In the area of model selection for ARMA models, we propose and compare different robust model order selection criteria that are based on the BIP τ-estimator.

Full textAbstract:
Page segmentation is one of the important and basic research subjects of document analysis. Traditionally, there are two major kinds of page segmentation approaches. One is the top-down approach and the other is the bottom-up approach. Though these two approaches are been used till now, they are not effective for processing documents with high geometrical complexity and the process of splitting document needs iterative operations which is time consuming. The Modified Fractal Signature (MFS) approach which was presented in recent years can overcome the above weaknesses, however it needs to calculate modified fractal signature which makes the theory and the algorithm very complex. In this thesis, we present two new page segmentation approaches (one is the Maximum Order Statistic Filter (MaxOSF) approach, the other is the Median Order Statistic Filter (MexOSF) approach) based on the order statistic filter (OSF) which is more direct and much simpler. We use the MedOSF to remove the salt-pepper noise of the document and use the MaxOSF to do the page segmentation. In practice, they not only can adaptively process the documents with high geometrical complexity, but also save a lot of computing time.

Full textAbstract:
Eigenstructure based techniques have been studied extensively in the last decade to estimate the number and locations of incoming radiating sources using a passive sensor array. One of the early limitations was the computational load involved in arriving at the eigendecompositions. The introduction of VLSI circuits and parallel processors however, has reduced the cost of computation A tremendously. As a consequence, we study eigendecomposition algorithms with highly parallel and A localized data flow, in order to take advantage of VLSI capabilities.
This dissertation presents a fast Recursive/Iterative Toeplitz (Hermitian) Eigenspace (RITE) algorithm, and its extension to the generalized strongly regular eigendecomposition situation (C-RITE). Both procedures exhibit highly parallel structures, and their applicability to fast passive array processing is emphasized. The algorithms compute recursively in increasing order, the complete (generalized) eigendecompositions of the successive subproblems contained in the maximum size one. At each order, a number of independent, structurally identical, non-linear problems is solved in parallel. The (generalized) eigenvalues are found by quadratically convergent iterative search techniques. Two different search methods, a restricted Newton approach and a rational approximation based technique are considered. The eigenvectors are found by solving Toeplitz systems efficiently. The multiple minimum (generalized) eigenvalue case and the case of a cluster of small (generalized) eigenvalues are treated also. Eigenpair residual norms and orthonormality norms in comparison with IMSL library routines, indicate good performance and stability behavior for increasing dimensions for both the RITE and C-RITE algorithms.
Application of the procedures to the Direction Of Arrival (DOA) identification problem, using the MUSIC algorithm, is presented. The order-recursive properties of RITE and C-RITE permit estimation of angles for all intermediate orders imbedded in the original problem, facilitating the earliest possible estimation of the number and location of radiating sources. The detection algorithm based on RITE or C-RITE can then stop, thereby minimizing the overall computational load to that corresponding to the smallest order for which angle of arrival estimation is indicated to be reliable.
Some extensions of the RITE procedure to Hermitian (non-Toeplitz) matrices are presented. This corresponds in the array processing context to correlation matrices estimated from non-linear arrays or incoming signals with non-stationary characteristics. A first—order perturbation approach and two Subspace Iteration (SI) methods are investigated. The RITE decomposition of the Toeplitzsized (diagonally averaged) matrix is used as a starting point. Results show that the SI based techniques lead to good approximation of the eigen-information, with the rate of convergence depending upon the SNR ar1d the angle difference between incoming sources, the convergence being faster than starting the SI method from an arbitrary initial matrix.Ph.

Full textAbstract:
Financial data is often represented with rows of values, contained in a dataset. This data needs to be transformed into a common format in order for comparison and matching to be made, which can take a long time for larger datasets. The main goal of this master’s thesis is speeding up these transformations through parallelization using Python multiprocessing. The datasets in question consist of several rows representing trades, and are transformed into a common format using rules known as filters. In order to devise a parallelization strategy, the filters were analyzed in order to find ordering constraints, and the Python profiler cProfile was used to find bottlenecks and potential parallelization points. This analysis resulted in the use of a task-based approach for the implementation, in which the transformation was divided into an initial sequential pre-processing step, a parallel step where chunks of several trade rows were distributed among workers, and a sequential post processing step. The implementation was tested by transforming four datasets of differing sizes using up to 16 workers, and execution time and memory consumption was measured. The results for the tiny, small, medium, and large datasets showed a speedup of 0.5, 2.1, 3.8, and 4.81. They also showed linearly increasing memory consumption for all datasets. The test transformations were also profiled in order to understand the parallel program’s behaviour for the different datasets. The experiments gave way to the conclusion that dataset size heavily influences the speedup, partly because of the fact that the sequential parts become less significant. In addition, the large memory increase for larger amount of workers is noted as a major downside of multiprocessing when using caching mechanisms, as data is duplicated instead of shared. This thesis shows that it is possible to speed up the dataset transformations using chunks of rows as tasks, though the speedup is relatively low.Finansiell data representeras ofta med rader av värden, samlade i en datamängd. Denna data måste transformeras till ett standardformat för att möjliggöra jämförelser och matchning. Detta kan ta lång tid för stora datamängder. Huvudmålet för detta examensarbete är att snabba upp dessa transformationer genom parallellisering med hjälp av Python-modulen multiprocessing. Datamängderna omvandlas med hjälp av regler, kallade filter. Dessa filter analyserades för att identifiera begränsningar på ordningen i vilken datamängden kan behandlas, och därigenom finna en parallelliseringsstrategi. Python-profileraren cProfile an- vändes även för att hitta potentiella parallelliseringspunkter i koden. Denna analys resulterade i användandet av ett “task”-baserat tillvägagångssätt, där transformationen delades in i ett sekventiellt pre-processingsteg, ett parallelt steg där grupper av rader distribuerades ut bland arbetar-processer, och ett sekventiellt post-processingsteg. Implementationen testades genom transformation av fyra datamängder av olika storlekar, med upp till 16 arbetarprocesser. Resultaten för de fyra datamängderna var en speedup på 0.5, 2.1, 3.8 respektive 4.81. En linjär ökning i minnesanvändning uppvisades även. Experimenten resulterade i slutsatsen att datamängdens storlek var en betydande faktor i hur mycket speedup som uppvisades, delvis på grund av faktumet att de sekventiella delarna tar upp en mindre del av programmet. Den stora minnesåtgången noterades som en nackdel med att använda multiprocessing i kombination med cachning, på grund av duplicerad data. Detta examensarbete visar att det är möjligt att snabba upp datamängdstransformation genom att använda radgrupper som tasks, även om en relativt låg speedup uppvisades.

Full textAbstract:
This thesis presents accounts of a range of linguistic phenomena in an extended categorial framework, and develops proposals for processing grammars set within this framework. Linguistic phenomena whose treatment we address include word order, grammatical relations and obliqueness, extraction and island constraints, and binding. The work is set within a flexible categorial framework which is a version of the Lambek calculus (Lambek, 1958) extended by the inclusion of additional type-forming operators whose logical behaviour allows for the characterization of some aspect of linguistic phenomena. We begin with the treatment of extraction phenomena and island constraints. An account is developed in which there are many interrelated notions of boundary, and where the sensitivity of any syntactic process to a particular class of boundaries can be addressed within the grammar. We next present a new categorial treatment of word order which factors apart the specification of the order of a head's complements from the position of the head relative to them. This move has the advantage of allowing the incorporation of a treatment of grammatical relations and obliqueness, as well as providing for the treatment of Verb Second phenomena in Germanic languages. A categorial treatment of binding is then presented which integrates the preceding proposals of the thesis, handling command constraints on binding in terms of relative oliqueness and locality constraints using the account of linguistic boundaries. Attention is given to the treatment of long distance reflexivization in Icelandic, a phenomenon of interest because of its unusual locality behaviour. Finally, a method is developed for parsing Lambek calculus grammars which avoids the efficiency problems presented by the occurrence of multiple equivalent proofs. The method involves developing a notion of normal form proof and adapting the parsing method to ensure that only normal form proofs are constructed.

Full textAbstract:
Encoding time is one of the most important features of the mammalian brain. The visual system, comprising almost half of the brain is of no exception. Time processing enables us to make goal-directed behavior in the optimum “time window” and launch a ballistic eye movement, reach/grasp an object or direct our processing resources (attention) from one point of interest to another. In addition, encoding time is critical for higher cognitive functions, enabling us to make causal inferences. The limitations of temporal individuation in the visual stream seem to vary across the visual field: the resolution gradually drops as objects become farther away from the center of gaze, where little differences were found in terms of resolution for objects in the upper versus lower visual field. This resolution of temporal individuation is vastly different from the resolution ascribed to spatial individuation. If individuation is mediated through attention, as some researchers have proposed, the general term ”attention” seems to possess different properties, at least regarding temporal and spatial processing. Next we looked at another aspect of encoding time: Temporal Order Judgments (TOJ), where animals had to judge the relative timing onset of two visual events. After training two monkeys on the task, we recorded from neurons in the lateral intraparietal area (LIP), while the animals reported the perceived order of two visual stimuli. We found that LIP neurons show differential activity based on the animal’s perceptual choice: when the animal reports the stimulus inside the receptive field of the neuron as first, the cells show an increased level of activity compared to when the animal reports he same stimulus as second. This differential activity was most reliable in the tonic period of the response \((\sim100 ms\) after stimulus onset). However, no difference in visual response latencies was observed between the different perceptual choices. The parietal cortex has previously been implicated in temporal processing based on patient studies as well as neuroimaging investigations. Physiological studies have also suggested the involvement of parietal area in encoding elapsed time. However, our study is the first to demonstrate parietal neurons encoding relative timing.Psychology

Neurons in early visual cortex respond to luminance variations occurring at objects' boundaries. However, visual stimuli that are defined by non-luminance cues, such as texture or contrast, have been demonstrated to evoke neuronal responses in recent years. These stimuli have been termed as second-order stimuli, since they require more complex processing which involves essential nonlinear operations.In this thesis, I tested neuronal responses to various second-order stimuli in order to shed light on the underlying mechanisms. In particular, we addressed the following issues: (1) whether abutting gratings can be processed nonlinearly, as illusory contours formed by abutting lines; (2) Whether a single mechanism can mediate responses to two distinct second-order stimuli: abutting gratings and contrast envelopes; (3) whether cat A18 is a cortical locus for form-cue invariant boundary perception. Altogether, these results provide insight into higher order neuronal processing at early visual cortex and have some important indications for future studies.

This habilitation thesis has to primary goals. First, the often mentioned prejudice against higher order statistics, that a great number of data is necessary for accurate parameter estimation, should be proven. In fact, we show by theoretical analysis of different applications for higher order statistics that this prejudice is not true in general. The main conclusion is that the use of higher order statistics has to be proven case-by-case. The second goal is to present a new concept - so-called modulated cumulants - for identification of linear time invariant system. We show by simulations that these concept leads to very accurate estimates compared to known methods.

Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2006.This research investigates the ordering process between small suppliers and retailers and the role of the Internet in this process. Product ordering and fulfilment are both important components of a supply chain, of which suppliers and retailers are members. The Internet as an enabling technology has an important role to play in supply chains and therefore also in order processing. Internet technology facilitates Business-to-Business (B2B) transactions. Retailers and their suppliers collaborate to align production with customer demands. Internet-enabled B2B supports this collaboration between businesses, allowing them to gain knowledge about customer demands real-time. This enables them to determine the impact of these demands on their operations. Using the Internet has the advantage that it provides an ever present link that is less costly than private networks and Electronic Data Interchange (EDI). When the Internet is used to facilitate trade and commerce between businesses, ecommerce is established. With Internet-enabled B2B (or B2B e-commerce), multiple suppliers are connected to multiple customers. This reduces production cycle times, reduces inventory, improves speed and quality of communications and reduces costs. This research investigates suppliers in the retail supply chain and focuses more specifically on small businesses due to their reported importance in the South African economy. They provide employment to a large portion of the country's population and contribute almost half to the economic activity. Small suppliers form part of supply chains and have to adhere to the demands exerted by larger supply chain members in order to be included in such supply chains. Small suppliers have just as an important role to fulfil in supply chains as larger companies. Small suppliers are also responsible for connecting and integrating supply chain members and in so doing, reduce costs.

Full textAbstract:
Many systems take inputs, which can be measured and sometimes controlled, and outputs, which can also be measured and which depend on the inputs. Taking numerous measurements from such systems produces data, which may be used to either model the system with the goal of predicting the output associated with a given input (function approximation, or regression) or of finding the input settings required to produce a desired output (optimisation, or search). Approximating or optimising a function is central to the field of computational intelligence. There are many existing methods for performing regression and optimisation based on samples of data but they all have limitations. Multi layer perceptrons (MLPs) are universal approximators, but they suffer from the black box problem, which means their structure and the function they implement is opaque to the user. They also suffer from a propensity to become trapped in local minima or large plateaux in the error function during learning. A regression method with a structure that allows models to be compared, human knowledge to be extracted, optimisation searches to be guided and model complexity to be controlled is desirable. This thesis presents such as method. This thesis presents a single framework for both regression and optimisation: the mixed order hyper network (MOHN). A MOHN implements a function f:{-1,1}^n →R to arbitrary precision. The structure of a MOHN makes the ways in which input variables interact to determine the function output explicit, which allows human insights and complexity control that are very difficult in neural networks with hidden units. The explicit structure representation also allows efficient algorithms for searching for an input pattern that leads to a desired output. A number of learning rules for estimating the weights based on a sample of data are presented along with a heuristic method for choosing which connections to include in a model. Several methods for searching a MOHN for inputs that lead to a desired output are compared. Experiments compare a MOHN to an MLP on regression tasks. The MOHN is found to achieve a comparable level of accuracy to an MLP but suffers less from local minima in the error function and shows less variance across multiple training trials. It is also easier to interpret and combine from an ensemble. The trade-off between the fit of a model to its training data and that to an independent set of test data is shown to be easier to control in a MOHN than an MLP. A MOHN is also compared to a number of existing optimisation methods including those using estimation of distribution algorithms, genetic algorithms and simulated annealing. The MOHN is able to find optimal solutions in far fewer function evaluations than these methods on tasks selected from the literature.

Full textAbstract:
Numbers convey different meanings when used in different contexts (Wiese, 2003). In a cardinal context, a number will tell us how many entities are in a set and convey quantity meaning. In an ordinal context, a number will refer to the relative position (or rank) of one element within a sequence; non-numerical ordered series (e.g. the letters of the alphabet) can also be used to provide meaningful order information. Because quantity and order are linked up with each other in the cognitive number domain (the larger the quantity a number refers to, the later it is located in the conventional number sequence), the question of whether they rely on some common or distinct underlying mechanism(s) is theoretically relevant and was addressed in the present thesis. Experimental studies showed evidence of both similarities (similar distance and SNARC effects, recruitment of parietal and frontal regions, and conjoint impairment or preservation after brain damage) and dissociations (different developmental course, dissociation after cerebral lesion, and specific behavioural markers) between quantity and order neuro-functional processes. The aim of the present thesis was to clarify the relationship between numerical quantity and order processing and to test the hypothesis that they rely on (at least partially) dissociated mechanisms. We tested this hypothesis in a single case study, an electrophysiological study and in two behavioural experiments. In the neuropsychological study, we reported the case of patient CO, who showed Gerstmann syndrome after bilateral parietal damage and became unable to process sequence order relations (e.g. he couldn't recite the number sequence backwards, nor decide whether a number, letter, day or month comes before or after a given target in the corresponding sequence, and he was unable to verify the order of items in a pair). Nonetheless, the patient had largely preserved quantity processing abilities (he could compare numbers and dot patterns to find the smaller or larger, and showed a standard distance effect, he could produce a number smaller or larger than a given target, and match dot patterns with Arabic numerals). Overall, CO's pattern of performance was interpreted as reflecting the involvement of different mechanisms when processing quantity or sequence order relations. Our electrophysiological study corroborated this finding since different spatio-temporal patterns of the distance effect were observed when subjects had to process numbers in a quantity comparison task or in an order judgment task. Quantity processing elicited an early distance effect over the P2p component on left parietal sites, whereas the distance effect was slightly delayed and bilaterally distributed in the numerical order judgment task; and this latter task additionally recruited prefrontal regions on a later (P3-counterpart) component. Finally, our behavioural study further emphasized the involvement of different mechanisms underlying the processing of quantity and numerical order and provided some evidence about the nature of these specific mechanisms. In the number comparison (quantity) task, the standard distance effect was proposed to reflect the involvement of a magnitude comparison mechanism; whereas the reverse distance effect observed in the numerical order verification task was taken as evidence for the recruitment of a serial search (recitation) process. Besides, the pair-order effect was also found to specifically affect order but not quantity judgments. Taken together, the data collected in the present thesis lend further support to the hypothesis that quantity and numerical order rely on distinct processing mechanisms that can be damaged selectively after cerebral lesions, that recruit similar brain areas but with a different spatio-temporal course and that show specific behavioural markers.

Chapter 1 starts with providing the theoretical background against which the experimental work in this thesis can be viewed. It provides the main approaches, theories and views on consciousness and the main challenges in the field. Specifically, it does so in relation to first-order and second- order neuronal processing, which will be explained later on. Furthermore, Chapter 1 discusses the conscious brain in its larger context of an embodied mind and the environment in which the agent lives. Lastly, the final section reviews the possibility of consciousness being a social construct. Chapter 2 continues with examining what happens when information-processing is limited to first-order processing, which is the case when information remains subliminal. Subliminal information does get processed up to a certain level, since brain activity in response to the stimulus can be measured. Yet, it is not processed up to the level that renders the stimulus conscious. The study presented in Chapter 2 aims to answer whether perceptual information presented below the conscious threshold can still affect behaviour? The outcome of this and similar studies would tell us more about the possible functions of consciousness. If subliminal stimuli are not able to influence behaviour, it would suggest that consciousness is necessary in order to guide or regulate human behaviour. Chapter 3 discusses how (changes in) perceptual content influences the subjective experience of time, a concept that is highly related to consciousness. Consciousness inevitably needs a reference or content to be conscious of. Similarly, time needs external physical events to occur to have any meaning, since time is generally only defined in terms of changes of state, mass or energy. Atomic clocks measure time by detecting changes in energy levels of electrons in atoms and are the most accurate timekeepers we have with an error rate of only 1 second per 30 million years. Therefore, no matter how small the event is, without any such event like a change in physical state of the electron the concept of time would be meaningless. Thus, the concept of time would be completely irrelevant in a universe without mass or matter. In such a universe the passing of a single nanosecond would be exactly the same as a billion years. This dependence on external events is what makes time perception such an interesting topic to study in the field of consciousness. The critical question here is how subjective experience of time relates to conscious (changes in) perceptual content.Chapter 4 further explores the relationship between perceptual content and consciousness. The study described in this chapter examines the transition of first-order information to second-order processing. Does a gradual increase in first-order perceptual evidence result in similarly gradual judgments of subjective experience? This chapter discusses levels of representation, perceptual evidence and their effect on subjective judgments. The key question here is whether increasing perceptual evidence while maintaining a fixed level of representation will result in higher levels of subjective measures as well or whether such measures only increase with higher levels of representation. In short, can you be more or less conscious in a graded manner or is consciousness an all-or-none type of phenomenon? This answer will have important consequences for distinguishing between the main theories on consciousness since their predictions about graded consciousness differ and therefore could be strongly challenged by the answer to this question. Chapter 5 tests the idea of consciousness being an acquired ability rather than an innate property of the brain by examining the possibility of training or improving second-order processing, which is one of the key assumptions of the Radical Plasticity Theory. The study described in this chapter explores plasticity of consciousness by performing a perceptual learning study of multiple sessions over several days. The effects of this training paradigm on both first- and second order processing will be discussed in this chapter. Chapter 6 looks deeper into such second-order subjective judgments and what kinds of first- order information is used to make such judgments. It has been suggested that such measures of conscious experience not only incorporate sensory information but also includes information from non-sensory brain areas such as the motor cortex. In light of the sensorimotor accounts of consciousness the influence of motor cortex, and thus action, on the subjective experience of visual stimuli would be an important result and would support such accounts wherein perception and action are tightly intertwined. Finally, chapter 7 summarizes the main findings and discusses the results within the larger framework or first- and second order processing. It also addresses the consequences or implications of these findings for some of the most promising theories on consciousness, and Radical Plasticity thesis in particular.Doctorat en Sciences psychologiques et de l'éducation

Full textAbstract:
The wide spread use of limit states design procedures in both the Canadian and American
steel design codes has created a need for a better understanding of how structures behave. Current design practice, however, allows and often encourages engineers to use an approximate linear analysis to determine the member forces in a structure. This is then followed by an even more approximate amplification of forces through the use of several design equations. It is believed that this practice is no longer acceptible as more accurate second-order computer programs have become a very practical alternative.
With this as motivation, this thesis will provide a comparison between a second-order computer program available at the University of British Columbia called ULA (Ultimate Load Analysis) and the Canadian and American building code designs, CAN3-S16.1-M84 and LRFD 1986 respectively.
It was felt that ULA should be verified, even though the theory it is based on is well established. Thus, ULA was used to generate a load versus L/r curve for a pin ended column (with the parameters modified slightly to allow direct comparison with the curves available in the codes). ULA was then used to predict load-deflection curves for two existing test frames. The resulting curves compared well with the test data.
To ensure simplicity, the building codes make several approximations in the derivation of their design equations. This results in the equations being applicable to a very narrow range of structures. Specifically, the equations apply to rigidly connected frames in which all of the columns reach their critical buckling load simmultaniously. Consequently, the results from ULA were compared to the codes for structures of this type. It was found that the codes were conservative for these structures in relation to the results from ULA,
yet the amount of conservatism varied greatly between structures. That is, the codes are not consistant in how conservative they are. Results from ULA were then compared to the codes for structures that do not satisfy all of the code limitations. Alhough using the codes to design structures beyond the limit of applicability is not a recommended practice, engineers do use the codes to design all types of structures, with little appreciation for the applicability limits. Consequently, it was deemed appropriate to extend this study to such structures. Though only a few were investigated, it was found that the codes were unreliable, being highly conservative, very accurate, or in one case highly unconservative when compared to the results from ULA.Applied Science, Faculty of

Full textAbstract:
The Interface Hypothesis (Sorace and Filiaci, 2006) conjectures that adult second language learners (L2 learners) who have reached near-native levels of proficiency in their second language exhibit difficulties at the interface between syntax and other cognitive domains, most notably at the syntax-discourse interface. However, research in this area was limited, in that the data were offline, and thus unable to provide evidence for the nature of the deficit shown by L2 learners. This thesis presents online data which address the question of the underlying nature of the difficulties observed in L2 learners at the syntaxdiscourse interface. This thesis has extended work on the syntax-discourse interface in L2 learners by investigating the acquisition of two phenomena at the syntax-discourse interface in German: the role of word order and pronominalization with respect to information structure (Experiments 1-3), and the antecedent preferences of anaphoric demonstrative (the der, die, das series homophonous with the definite article) and personal pronouns (the er, sie, es series) (Experiments 4- 8). Crucially, this work has used an on-line methodology, the visual-world paradigm, which allows an insight into the incremental interpretation of interface phenomena in real-time processing. The data from these experiments show that L2 learners have difficulty integrating different sources of information in real-time comprehension efficiently, supporting the Interface Hypothesis. However, the nature of the processing difficulties which L2 learners demonstrate in on-line processing was not determined by these studies, resulting in the question: are L2 learners’ difficulties a result of a limitation of processing resources, or the inability to deploy those resources effectively? A novel dualtask experiment (Experiment 9), in which native speakers of German were placed under processing load simulated the results previously obtained for L2 learners. It is concluded that syntactic dependencies were constrained by resource limitation, whereas discourse based dependencies were constrained by processing resource allocation.

Full textAbstract:
Research within the Competition Model has shown that different language speakers use different strategies to interpret sentences. Despite the fact that crosslinguistic studies have incorporated a variety of cues in the experiments, studies investigating Mandarin used mostly word order and animacy cues only. Modifying experiment designs of the previous studies and adding agreement cues in the research, the present study presented subjects a series of both grammatical and ungrammatical English sentences and asked them to identify the "actor" of these sentences. One group of English native speakers and two groups of Taiwanese English learners with different English proficiency were recruited. Three research questions were investigated in the present study: (1) Which cues, word order, agreement and animacy, would be used most for the three different groups of subjects? (2) What kind of language transfer would be found in nonnative learners of English, especially Taiwanese high school students? (3) Would learners of English with different levels of proficiency differ in their use of cues in sentence processing? Findings of the present research indicated that English native speakers used word order as the primary cues, while intermediate and advanced Taiwanese English learners used mainly animacy and word order cues respectively, which demonstrated that a different length of exposure to a foreign language did influence learners' strategies in sentence processing. In addition, results of the present study also revealed a pattern of forward transfer in sentence processing by intermediate nonnative subjects, while the advanced group of subjects did not show this transfer. Interestingly, after modifying previous research designs, the effect of animacy cues in the group of English native speakers did not reach significance in the present study. This may shed light on the influence of real world bias in the previous studies.xv, 133 leaves

Full textAbstract:
This thesis first presents a pole-zero placement algorithm for the systematic design of high-order phase-locked loops (PLL) serving as anti-imaging and anti-aliasing filters for time-mode signal processing applications. A 6th order PLL is designed and fabricated on a printed circuit board and is interfaced to a production mixed-signal tester. The correct filtering operation and large-signal transfer characteristic of the PLL are verified with an all-digital DFT solution. The digital test input is driven by a single clock, which can be programmed directly from an ATE high-speed digital pattern generator. As application of these high-order PLLs, an accurate and low-cost clock delay generation system is presented. With proper compensation and calibration, a delay resolution of 15 ps is achieved over an 8.4 ns range. This technique is shown experimentally to be a viable solution for clock alignment and for measuring jitter at a 50 GHz effective sampling rate.Ce mémoire présente tout d'abord une approche systématique descendante pour la conception de boucles à verrouillage de phase (PLL) ayant un ordre arbitraire et opérant comme filtre anti-image ou anti-repliement pour le traitement de signal dans le domaine temporel. Un PLL de 6e ordre a été conçu et fabriqué sur une carte de circuit imprimé montée sur un tester à signaux-mixtes (ATE). La fonction de filtrage et la caractéristique de transfert de grands-signaux sont vérifiées à l'aide d'une solution de conception pour test (DFT) entièrement numérique. Le signal d'entrée numérique est cadencé par une horloge unique. Par conséquent, le signal de test peut être programmé sans effort à partir de l'instrument numérique à haute-vitesse (HSD) d'un testeur à signaux-mixtes (ATE). De plus, un système précis et économique de génération de délai d'horloge est présenté comme une application du PLL construit. A l'aide de calibration et compensation appropriées, une résolution de délai de l'ordre de 15 ps est réalisée pour un intervalle de 8.4 ns. Cette technique est démontrée expérimentalement comme étant une solution viable pour l'alignement d'horloge et pour mesurer le vacillement d'horloge à un rythme de sous-échantillonnage de 50 GHz.
