Повний текст джерелаThis thesis investigates closed-loop control for glycemia regulation of Type1 Diabetes Mellitus (T1DM). Two main controller categories are designed: non-model-based and model-based. To test their efficiency, both types are tested in silico on two T1DM simulators. The first is a long-term model that is derived from clinical data of T1DM subjects and the second is the Uva/Padova simulator. Firstly, Model-free Control (MFC) is designed: a variable reference intelligent Proportional (iP) control and a constant reference intelligent Proportional-Integral-Derivative (iPID). Better overall performance is yielded with iPID over iP and over a classic PID. Secondly, a positive Sliding Mode Control SMC is designed for the first time for glycemia regulation. The model-based controller is chosen for glycemia regulation due to its well-known robustness properties. More importantly, our main contribution is that SMC is designed to be positive everywhere in the positively invariant set for the plasma insulin subsystem. Finally, a positive state feedback controller is designed for the first time to regulate glycemia. The largest Positively Invariant Set (PIS) is found. Not only control positivity is respected but rather a tight glycemic control is achieved. When the system initial condition belongs to the PIS, hypoglycemia is prevented, otherwise future hypoglycemia is predicted for any initial condition outside the PIS

Повний текст джерелаThe task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations. The existing metod for controlling the robot is Linear Quadratic Control. To evaluate the SMC-methodology and compare it with the existing solution simulations using SMC and LQ-control are made with uncertainties and modeling imprecision. Our tests show that a control law based on SMC is robust and seems to be a very good alternative to the existing solution.

Повний текст джерелаThe conventional IRIG Instrumentation Tape Recorder has two major disadvantages when used to record and reproduce digital data. Firstly it has a limited number of discrete tape speeds, and secondly the operator has to calculate and then set the tape speed to give the appropriate packing density or clock rate. The use of microprocessors has made it possible to take the majority of these calculations, and also the setting up of the recorder, out of the users hands. Also the tape speeds available are virtually continuous over the range 17/8 ips to 120 ips. There are other facilities available and this paper describes the operation and facilities of an instrumentation recorder which is almost totally automatic.

Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät II, 2012. http://dx.doi.org/10.18452/16514.
Повний текст джерелаThis thesis provides a framework for the evaluation of first and higher-order derivatives and Taylor series expansions through large computer programs that contain numerical linear algebra (NLA) functions. It is a generalization of traditional algorithmic differentiation (AD) techniques in that NLA functions are regarded as black boxes where the inputs and outputs are related by defining equations. Based on the defining equations, structure-exploiting algorithms are derived. More precisely, novel algorithms for the propagation of Taylor polynomials through the QR, Cholesky,- and real-symmetric eigenvalue decomposition are shown. Recurrences for the reverse mode of AD, which require essentially only the returned factors of the decomposition, are also derived. Compared to the traditional approach where all intermediates of an algorithm are stored, this is a reduction from O(N^3) to O(N^2) for algorithms with O( N^3) complexity. N denotes the matrix size. The derived algorithms make it possible to use existing high-performance implementations. A runtime comparison shows that the treatment of NLA functions as atomic can be more than one order of magnitude faster than an automatic differentiation of the underlying algorithm. Furthermore, the computational graph is orders of magnitudes smaller. This reduces the additional memory requirements, as well as the overhead, of operator overloading techniques to a fraction.

Повний текст джерелаIl est possible, bien sûr, d'utiliser une approche empirique pour optimiser un procédé. Néanmoins il y a des avantages à choisir une approche analytique puisqu'on peut en attendre des avancées significatives dans la compréhension des interactions dynamiques présentes dans l'arc. C'est pourquoi nous présentons dans le chapitre 2 les connaissances théoriques de la physique quant au comportement du métal liquide transféré en soudage MIG/MAG.
Ce travail comporte donc également un aspect expérimental nécessaire à l'élaboration des bases de données utilisées pour la construction des modèles. Les différents enregistrements ont été effectués au CTAS sur une plate forme équipée d'un système d'acquisition de données pour les mesures de tension, courant, vitesse fil et d'un système de vidéo rapide. Le chapitre 3 présente notre recherche d'une méthode de segmentation permettant d'obtenir le suivi de variables pertinentes. Nous y proposons un capteur logiciel basé sur la théorie des contours actifs et montrons de bons résultats obtenus sur des vidéos expérimentales.
Une étape d'ajustement de certains paramètres est indispensable. Elle est donnée dans le chapitre 4. Le simulateur créé permet d'interpréter certains phénomènes importants en soudage, de réaliser une étude de sensibilité « sans risque » et de donner les signatures théoriques de défauts.

Повний текст джерелаSevere brain injuries may lead to the disruption of long-range inter-region brain communications resulting in chronic Disorders of Consciousness (DoC). Electrical Deep Brain Stimulation (DBS) of the Thalamus has been reported to modulate arousal and ameliorate behavior in Minimally Conscious State (MCS) patients. However, there is no clear demonstration of the cerebral mechanisms for the specific and causal restoration of conscious access, i.e. awareness, with DBS. Here we hypothesized that specific thalamic DBS might restore both arousal and awareness through the restoration of thalamo-cortical activity and the subsequent reorganization of cortical dynamics. We first designed an experimental set-up combining DBS and functional Magnetic Resonance Imaging (fMRI) in Non-Human Primate (NHP) and applied finely tuned anesthesia to suppress consciousness. We recorded whole brain activity and developed a preprocessing pipeline, Pypreclin, to tackle the electrode-induced artifact. During deep sedation, Centro-Median Thalamic (CMT) DBS robustly induced arousal in an ON-OFF fashion. When CMT DBS was switched ON, fMRI signal increased in prefrontal, parietal and cingulate cortices, and gradually returned to baseline seconds after the stimulator was turned OFF. Moreover, CMT DBS led to a reconfiguration of Resting State cortical dynamics bydecreasing the function-structure similarity, previously described as a consciousness signature. Finally, CMT DBS restored a broad hierarchical response to global auditory regularities that was disrupted under general anesthesia. Thus, CMT DBS restored the two main dimensions of consciousness, i.e. arousal and awareness, paving the way to its therapeutical translation in patients with chronic DoC

Des commandes non linéaires par modes glissants d'ordre supérieur mono et multi variables sont appliquées sur le système électropneumatique lui assurant une convergence en temps fini et la robustesse face aux incertitudes paramétriques et aux perturbations, ce qui constitue une des principales contributions de ce travail. Par ailleurs, dans le but de minimiser le nombre de capteurs et/ou pallier à leur défaillance, la synthèse d'observateurs pour cette plateforme expérimentale a été étudiée. Ainsi, une étude de l'observabilité, une synthèse d'observateurs à grands gains et par modes glissants a été effectuée.

Повний текст джерелаSen, Sagar. "Automatic effective model discovery." Rennes 1, 2010. http://www.theses.fr/2010REN1S042.
Повний текст джерелаScientific discovery often culminates into representing structure in nature as networks (graphs) of objects. For instance, certain biological reaction networks aim to represent living processes such as burning fat or switching genes on/off. Knowledge from experiments, data analysis and mental tacit lead to the discovery of such effective structures in nature. Can this process of scientific discovery using various sources of knowledge be automated? In this thesis, we address the same question in the contemporary context of model-driven engineering (MDE) of complex software systems. MDE aims to grease the wheels of complex software creation using first class artifacts called models. Very much like the process of effective structure discovery in science a modeler creates effective models, representing useful software artifacts, in a modelling domain. In this thesis, we consider two such modelling domains: metamodels for modelling languages and feature diagrams for Software Product Lines (SPLs). Can we automate effective model discovery in a modelling domain? The central challenge in discovery is the automatic generation of models. Models are graphs of inter-connected objects with constraints on their structure and the data contained in them. These constraints are enforced by a modelling domain and heterogeneous sources of knowledge including several well-formedness rules. How can we automatically generate models that simultaneously satisfy these constraints? In this thesis, we present a model-driven framework to answer this question. The framework for automatic model discovery uses heterogeneous sources of knowledge to first setup a concise and relevant subset of a modelling domain specification called the effective modelling domain. Next, it transforms the effective modelling domain defined in possibly different languages to a constraint satisfaction problem in the unique formal specification language Alloy. Finally, the framework invokes a solver on the Alloy model to generate one or more effective models. We embody the framework in two tools: Cartier for model discovery in any modelling language and Avishkar for product discovery in a SPL. We validate our framework through rigorous experiments in test model generation, partial model completion, product generation in SPLs, and generation of web-service orchestrations. The results qualify that our framework consistently generates effective findings in modelling domains from commensurate case studies

Повний текст джерелаThe aim of this thesis is to propose a speech emotion recognition (SER) system for application in classroom. This system has been built up using novel features based on the amplitude and frequency (AM-FM) modulation model of speech signal. This model is based on the joint use of empirical mode decomposition (EMD) and the Teager-Kaiser energy operator (TKEO). In this system, the discrete (or categorical) emotion theory was chosen to represent the six basic emotions (sadness, anger, joy, disgust, fear and surprise) and neutral emotion.Automatic recognition has been optimized by finding the best combination of features, selecting the most relevant ones and comparing different classification approaches. Two reference speech emotional databases, in German and Spanish, were used to train and evaluate this system. A new database in French, more appropriate for the educational context was built, tested andvalidated

Повний текст джерелаSoftware can be tested either manually or automatically. The two approaches are complementary: automated testing can perform a huge number of tests in short time or period, whereas manual testing uses the knowledge of the testing engineer to target testing to the parts of the system that are assumed to be more error-prone. Despite this contemporary, tools for manual and automatic testing are usually different, leading to decreased productivity and reliability of the testing process. Auto Test is a testing tool that provides a “best of both worlds” strategy: it integrates developers’ test cases into an automated process of systematic contractdriven testing. This allows it to combine the benefits of both approaches while keeping a simple interface, and to treat the two types of tests in a unified fashion: evaluation of results is the same, coverage measures are added up, and both types of tests can be saved in the same format. The objective of this paper is to discuss the Importance of Automation tool with associate to software testing techniques in software engineering. In this paper we provide introduction of software testing and describe the CASE tools. The solution of this problem leads to the new approach of software development known as software testing in the IT world. Software Test Automation is the process of automating the steps of manual test cases using an automation tool or utility to shorten the testing life cycle with respect to time.

Complex systems such as commercial aircraft are difficult for operators to manage. Designers, intending to simplify the interface between the operator and the system, have introduced automation to assist the operator. In most cases, the automation has helped the operator, but at times operator confusion as to what the automation is doing has created dangerous situations that lead to property damage or loss of life. This problem, known as mode confusion, has been difficult to analyze and thus solutions tend to be reactive instead of proactive. This thesis examines mode confusion as an emergent property of the operator and the automation. It develops models of the automation and the operator and then studies their emergent behavior. It then applies the model in a case study.

Повний текст джерелаThe safety verification of distributed programs, that are based on reliable, unbounded fifo communication, leads in a straight line to model checking of infinite state systems. We introduce the family of (q)ueueing (c)oncurrent (p)rocesses (QCP): local transition systems, e.g., (pushdown-)automata, that are globally communicating over fifo channels. QCP inherits thus the known negative answers to the control-state reachability question from its members, above all from communicating automata and multi-stack pushdown systems. A feasible resolution of this question is, however, the corner stone for safety verification.We present two solutions to this intricacy: first, an over-approximation in the form of an abstract-check-refine algorithm on top of our novel notion of path invariant based refinement. This leads to a \cegar semi-algorithm that is implemented with the help of QDD and realized in a small software framework (McScM); the latter is benchmarked on a series ofsmall example protocols. Second, we propose restrictions for QCP with local pushdowns that untangle the causal interaction of local data, i.e., thestack, and global synchronization. We prove that an existential boundedness condition on runs together with an architectural restriction, that impedes the synchronization of two pushdowns, is sufficient and leads to an EXPTime-complete decision procedure (thus subsuming and generalizing known results). The underlying construction relies on a control-state reachability equivalent simulation on a single pushdown automaton, i.e., the context-freeness of the runs under the previous restrictions. We can demonstrate that our constraints arise ``naturally'' in certain classes of practical situations and are less restrictive than currently known ones. Another possibility to gain a practicable solution to safety verification involves limiting the decision question itself: we show that bounded phase reachability is decidable by a constructive algorithms in 2ExpTime, which is complete.Finally, trying to directly extend the previous positive results to model checking of linear temporal logic is not possible withouteither sacrificing expressivity or adding strong restrictions (i.e., that are not usable in practice). However, we can lift our context-freeness argument via hyperedge replacement grammars to graph-like representation of the partial order underlying each run of a QCP. Thus, we can directly apply the well-known results on MSO model checking on graphs (of bounded treewidth) to our setting and derive first results on verifying partial order properties on communicating (pushdown-) automata

Повний текст джерелаIn the modern world, Internet has become a popular place, people with speech hearing disabilities and search engines can't take part of speech content in podcast les. In order to solve the problem partially, the Sphinx decoders such as Sphinx-3, Sphinx-4 can be used to implement a Auto Transcript Generator application, by coupling already existing large acoustic model, language model and a existing dictionary, or by training your own large acoustic model, language model and creating your own dictionary to support continuous speaker independent speech recognition system.

Повний текст джерелаun rôle primordial dans l'amélioration de la disponibilité opérationnel le
des équipements. Dans les systèmes industriels, une part importante
(jusqu'à 80%) est consacrée à la maintenance, test et diagnostic. Pour
des systèmes complexes, la résolution des problèmes liés au diagnostic
et d'une manière générale de la supervision nécessite la mise en oeu-
vre d'une approche générique. Le diagnostic concerne les deux phases
indissociables de détection et de localisation. Dans cette thèse nous
proposons une approche dynamique de diagnostic pour les systèmes à
événements discrets. L'approche proposée basée sur l'exploitation du
temps, est applicable à tout système dont l'évolution dynamique dépend
non seulement de l'ordre des événements discrets mais aussi de la durée
des tâches associées comme pour les processus de communication ou les
processus batch. Dans cette thèse, le diagnostic des fautes est réalisé
grâce à l'implémentation d'un modèle basé sur l'utilisation des auto-
mates temporisés. L'objectif est de concevoir un observateur pour un
système donné, qui permet de détecter et localiser les éventuel les dé-
fail lances du procédé. Cet observateur est appelé “diagnoser”. Une
défail lance est constatée lorsque le séquencement temporel en sortie est
incorrect. Nous présentons donc les différentes étapes de la démarche
de diagnostic : la construction du diagnoser, la vérification du modèle
ainsi qu'une l'application de la démarche sur un exemple réel avec son
extension aux systèmes hybrides.
