Lionel, Sagayaraj Linushiya Ranjani. "Gene Expression Analysis of Loto-Type Toll Receptors in the Onychophoran Euperipatoides kanangrensis." Thesis, Uppsala universitet, Institutionen för geovetenskaper, 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-334158.
Full textAbstract:
The expression and role of Loto genes was previously investigated in arthropods and it was concluded that the morphogenetic functions of Loto genes were conserved in the last common ancestors of arthropods. In this paper, possible orthologs of Loto clade genes are analysed and it was found that they possibly play a conserved role in convergent extension of cells from the blastoderm stage to germ band extension stage. The differences and similarities in the number of and expression of Loto clade genes in arthropods and onychophorans are compared and analysed. Unlike in arthropods, the expression of Euperipatoides Loto is strongest in the head including part of the somewhat enigmatic frontal appendages (the onychophoran antennae). I also find a stripped segmental pattern of expression that is similar to that classic expression in transverse segmental stripes of Loto class genes as seen in arthropods. However, these stripes are only week and appear to be mesodermal rather than ectodermal, as in arthropods. These facts are discussed in regard to current hypothesis about the origin of segmentation in panarthropods.Insects, crustaceans and chelicerates each possess a set of several Loto class genes which are also involved in convergent extension. But the myriapod Strigamia only appears to possess one such gene. I therefore investigated Loto genes in another distantly related myriapod, Glomeris. It appears to only have one Loto gene and this appears to be involved in convergent extension as well. Two Toll genes of Glomeris (Gm-567 and Gm-596) were incomplete and could according to phylogenetic analysis represent Loto genes. I therefore checked their expression and found that they are not expressed like Loto genes. A third potential Glomeris Loto gene (Gm-399) could not be isolated via PCR.My data suggest a somewhat different role for onychophoran Loto than convergent extension, and that the ancestral set of panarthropod Loto genes may be one, rather than a set.<br>Loto-genernas roll och uttryck var tidigare undersökt inom leddjur och slutsatsen var att morfogenetiska funktioner av Loto-gener var konserverade hos närmsta förfäderna till leddjuren. I denna artikel/rapport studerades ortologer till Loto-generna, vilket kunde konstateras att dessa förmodligen har en viktig roll i konvergent förlängning (convergent extension) av celler från blastoderma stadiet till germ band stadiet. Skillnader och likheter i uttryck av Loto-gener inom leddjur och Onychophora (klomaskar) jämfördes och analyserades. Olikt från leddjur så var uttrycket av Euperipatoides Loto som starkast i antennen vid huvudet på Onychophora. Jag kunde också se ett segmenterat mönster av uttrycket som är liknande de uttryck i form av segmentell band som återfinns i klassen Loto-gener hos leddjuren. Dessa är dock svaga och verkar bara vara mesodermala snarare än ektodermala som hos leddjur. Dessa fakta diskuteras kring hypotesen kring ursprunget om segmentering hos Panarthropoda.Insekter, kräftdjur och palpkäkar har alla flera klasser av Loto gener som även de är inblandade konvergent förlängning. Men, myriapod Strigamia har bara en Loto-gen. Därför valde jag att utforska de Loto-gener i en annan långt relaterad myriapod kallad Glomeris. Det verkar som Glomeris har en Loto-gen och den är involverad i konvergent förlängning också. Två Toll-gener från Glomeris (Gm-567 och Gm-596) var inte kompletta och kunde representera Loto-gener enlig analys från phylogenetiskt träd. Därför kollade jag uttrycket på dessa gener och kunde se att de inte var uttryckta i samma grad som Loto-gener. En tredje potentiell Glomeris Loto-gen (Gm-399) kunde inte bli isolerad med hjälp av PCR.Min data tyder på att klomaskars Loto-gener har en annan roll än konvergent förlängning och attpanarthropods kanske bara hade en Loto-gene istället för ett set av gener.

The main objective of the study was to determine the risk(s) associated with lockout/tagout of hazardous energy and propose a new LOTO procedure which tracks the implementation of LOTO to mitigate against identified risks as a basis for promotion of safety. The study focuses on electrical personnel working in PHCN. Only electrical accident risks are examined, not other types of risk e.g. mechanical, chemical, and nuclear.
To gather material for this study, a questionnaire was distributed amongst electrical workers in PHCN and their supervisors were interviewed. Relevant literature and publications were studied as reference.
According to electrical personnel experience, electrocution, arc flash, arc blast, burns and lockout and tagout of the wrong electrical circuit are seen as the biggest electrical safety risk with regards to LOTO of hazardous energy.
The research reveals new information about electrical accident risks. This information is used to create a procedure for tracking LOTO of hazardous energy.

Full textAbstract:
This thesis examines why and how art is collected and used by modern corporations. Primarily, the study is focused on Alcan Aluminium Ltd., but for purposes of comparison and illumination, substantial attention is paid to Martineau Walker, Loto-Quebec and the Banque Nationale du Canada, all Montreal-based companies that have collected art for at least twenty years.<br>An historical introduction outlining the relationship between the arts and business---from the Renaissance in Europe to its place of greatest expansion in the nineteenth and twentieth centuries; in the U.S.A. as well as in Canada---begins the discussion. An attempt is made to position the activities of modern corporate art collecting between two poles---that of the individual collector and that of the institutional art museum.<br>Motives for collecting include, among many, the search for distinction and the desire to create a perception in the community of humanitarian standards guiding the corporation. The ways in which corporate motives contribute to the creation of a positive external corporate art identity, and thus a productive business environment, are examined and developed, as are the principal objections of their chief public detractor, artist-writer Hans Haacke.<br>In three of the four corporations studied, original research on the behavioural and emotional reactions of employees to the corporate art surrounding them has allowed an in-depth analysis of the internal effects of art on employees. Foremost among these are feelings of pride, well-being and the enhancement of self-identity.<br>Finally, a brief discussion of the role of mediators is offered, in particular that of the corporate curator in the modern art world.

Com o objectivo de identificar os determinantes de receitas dos Jogos Sociais do Estado em Portugal, foram recolhidos os dados referentes às vendas dos jogos do tipo Loto nos canais de distribuição mediador e Portal de Jogos, na Internet. Após a aplicação de diversos testes estatísticos concluiu-se que a relação da variação do volume de vendas no Portal face à existência de jackpot no primeiro prémio é estatisticamente significativa, ao contrário do que acontece na rede de mediadores, demonstrando-se a diferença de comportamento dos apostadores nos dois canais. Foi ainda provado que há uma relação estatisticamente significativa entre as vendas do jogo Euromilhões, tanto na rede de mediadores como no Portal de Jogos, e as vendas dos outros jogos nos mesmos canais, provando-se o efeito de complementaridade entre o jogo multi-estatal e os jogos nacionais do mesmo tipo Loto.<br>Social Games are games whose profits are applied on the so-called social causes, or "good cause", supporting disadvantaged population groups or social supporting programmes. With the purpose of identifying the determinants of Social gaming revenue in Portugal, data were collected concerning sales of Lotto type games, in both distribution channels: retailer and the gaming Portal on the Internet. After the application of various statistic tests, it was proved that the ratio of the change in the volume of sales on the Portal, face the existence of jackpot in first prize, is statistically significant, unlike in the network of retailers, showing the difference in the behavior of bettors in this two channels. It was also shown that there is a statistically significant relationship between the Euromillions game sales, both within the network of retailers as well as at the gaming Portal, and the sales of the other games in the same channels. This proves the effect of complementarily between the game multi-state and national games of the same type Lotto.

Full textAbstract:
<p> Along the coastlines of the Hawaiian Islands, there is a valuable and critical resource known for its brackish water habitat – loko i‘a (Hawaiian fishponds). They are dynamic systems dependent on the balance between fresh groundwater inputs from uka (uplands) and landward flow of kai (seawater), which all vary depending on the behavior of our climate, including rainfall, tides, and storms. Nutrient-rich groundwater mixing with the seawater at the coast allows for an abundant growth of limu or primary productivity attracting many of Hawaii’s favorable native brackish water and herbivorous species. Having an intimate relationship with this natural coastal nursery, Hawaiians effectively modified these coastal habitats into loko i’a to provide a sustainable food source for the communities in which they reside. In support of these invaluable resources and practices, this study seeks to understand primary productivity and salinity relationships along the same coastline at Honokea Loko of Waiuli, and Hale o Lono and Waiāhole/Kapalaho of Honohononui, Hawaii. Weekly water quality monitoring by kiai' loko (fishpond steward) and biweekly water column sampling, salinity in the three loko i’a ranged from 3.1 to 18.8 and was significantly different throughout different areas of each pond. Benthic primary productivity experiments, found significantly more growth at higher salinity locations across all sites. Due to these strong correlations, loko i'a communities would greatly benefit from these methodologies to quantify the variability of environmental changes through time and specific impacts of climate phenomena, changes in rainfall and sea level. These factors have the potential to interfere with primary productivity and alter loko i'a systems interactions entirely.</p><p>

Atliktas tyrimas su skirtingomis moksleivių grupėmis, kurio metu buvo nustatyta kad pradedant mokinius mokinti nuo procedūrinio programavimo, skatinamas jų savarankiškumas bei ugdomi konstruktyvaus programavimo įgūdžiai.
Konstravimo mokymąsi gerai apibūdina frazė „mokymasis kuriant“ (angl. Learning by making). Tokį mokymąsi realizuoti padeda informacinės ir komunikacinės technologijos.
Pradininkas – Seymouras Papertas – žymus matematikas, informatikas ir edukologas, vienas iš dirbtinio intelekto teorijos ir Logo programavimo pradininkų. Jau prieš išleidžiant „Minčių audras“ Papretas savo laboratorijoje Masačiusetso technologijos institute tyrinėjo, kokia programinė įranga būtų tinkamiausia vaikams dirbant kompiuteriu. Tada, 7-ajame dešimtmetyje (1967–1968) ir buvo sukurtos pirmosios programos, išreiškiančios S. Paperto Logo idėjas.

The comparative analysis of two programming languages – Logo and Pascal – was done. Their suitability according the pupil’s age was relieved. Nine programming languages were reviewed and their suitability for teaching was investigated.
Olympiad works of the republic of Lithuania were reviewed and the complexity of the tasks for older age pupils was analyzed. The pupils creativity was taken into account also.
The research with different groups of pupils was done and it was determined that while starting to teach pupils from procedural programming the independence and constructive programming skills are encouraged.
The phrase “Learning by making“ is the best description of the construction learning. The information and communication technologies help to realize such type of learning.
Seymour Papert (born February 29, 1928) is well known mathematician, computer scientist, and educator. He is one of the pioneers of artificial intelligence, as well as an inventor of the Logo programming language. Papert in his laboratory at Massachusetts Institute of Technology was searching for the best software for children to work with computer at his researches. Then in 1970-th the first programs that expressed Papert’s ideas were developed... [to full text]

Full textAbstract:
Digital image watermarking is used to protect the copyright of digital images. In this thesis, a novel blind logo image watermarking technique for RGB images is proposed. The proposed technique exploits the error correction capabilities of the Human Visual System (HVS). It embeds two different watermarks in the wavelet/multiwavelet domains. The two watermarks are embedded in different sub-bands, are orthogonal, and serve different purposes. One is a high capacity multi-bit watermark used to embed the logo, and the other is a 1-bit watermark which is used for the detection and reversal of geometrical attacks. The two watermarks are both embedded using a spread spectrum approach, based on a pseudo-random noise (PN) sequence and a unique secret key. Robustness against geometric attacks such as Rotation, Scaling, and Translation (RST) is achieved by embedding the 1-bit watermark in the Wavelet Transform Modulus Maxima (WTMM) coefficients of the wavelet transform. Unlike normal wavelet coefficients, WTMM coefficients are shift invariant, and this important property is used to facilitate the detection and reversal of RST attacks. The experimental results show that the proposed watermarking technique has better distortion parameter detection capabilities, and compares favourably against existing techniques in terms of robustness against geometrical attacks such as rotation, scaling, and translation.

La vente part lots consiste a vendre un ensemble de biens ou de services dans des quantites fixees a la conclusion du contrat, le tout a un prix unique. L'objet de ce travail est, premierement, d'expliquer l'usage de la vente par lots et de comprendre pourquoi les firmes n'ont pas choisi de vendre leurs biens separement sur les marches. Par exemple, nous verrons que la vente par lots est une maniere de mener une politique de discrimination par les prix ou de differenciation des produits. Deuxiemement, d'etudier les implications de la vente par sur la politique de la concurrence. Les differentes cours de justice en europe et aux etats-unis condamnent "per se" (par nature) la vente par lots lorsque les firmes possedent un pouvoir de marche sur l'un des biens lies. On commentera cette jurisprudence avec le recent proces microsoft dans l'industrie des logiciels.

Studiens syfte var att i samarbete med företaget Vendanor ta fram en produkt som gör nyckelöverlämning mellan två parter kontaktfri och säker. En marknadsundersökning, kundundersökning och litteraturstudie utfördes följt av identifikation av nödvändiga krav med hjälp av en QFD-matris. Tre koncept genererades med hjälp av mind map, morfologisk matris, personas, modeller, brainstorming och kundresa. Av de tre framtagna koncepten ”Box”, ”Pelare” och ”Logo” var de två förstnämnda nyckelskåp för traditionella nycklar och det sistnämnda för nyckelkort. Volymoch CAD-modeller blev skapade för alla tre koncept. Med hjälp av en Pughs matris bestämdes fortsatt iteration av nyckelskåpet ”Logo”. Riskanalys och scenarier skapades för det valda konceptet. Vidareutvecklingen av koncept ”Logo” innefattade även dimensionering av konceptets motorer, strömtillförsel och lager. En numerisk beräkning i COMSOL utfördes för att säkerställa hållfastheten vid upphängningspunkterna. Den slutgiltiga produktens form är inspirerad av Vendanors logotyp. Produkten har plats för 419 kort och väger ca 30,9 kg. Totalt åtta av produktens delar skal tillverkas. För dessa blevtillverkningsunderlag skapade med hjälp av CAD. 67 av produktens komponenter ska köpas in. Dessa komponenter presenteras i en inköpslista. Nyckelautomaten kan användas kontaktfritt via en smartphone alternativt via skärmen som är centrerad på produktens front. Intressenter för produkten är hotell, campingplatser, gym, simhall och övriga aktörer som använder sig utav nyckelkort.<br>The purpose of the study was to, in collaboration with Vendanor develop a product that enables key transactions between two parties contactless and safe. A market research, customer survey and literature study were performed followed by an identification of requirements by the help of a QFD matrix. Three concepts were generated with the help of a morphology matrix, mind map, customer journey, models, brain storming and personas. Of the three concepts ”Box”, ” Pelare” and ”Logo” the two former were key cabinets for traditional keys and the latter for key cards. Volume- and CAD-models were created for all three concepts. With the help of a Pughs matrix, continued iteration of the key cabinet "Logo" was determined. Risk analysis and scenarios were created for the chosen concept. Further iterations of the “Logo” concept included dimensioning of the motors, electricity supply and plain bearings. A numerical calculation in COMSOL was also performed to ensure the strength at the wall mounting points. The shape of the final product is inspired from Vendanors logotype. The product has a capacity of 419 cards and weighs approximately 30.9 kg. There are in total eight parts that will be manufactured. For these parts a manufacturing basis was created with CAD. The remaining 67 parts are going to be purchased. The specifications of these were presented in a Bill of Materials. The key machine can be used contactless via a smartphone or via the screen centered on the products front. Stakeholders for this product are hotels, campsites, gyms and other businesses using key cards.

Dans l’industrie et en particulier dans le domaine de l’automobile, il est aujourd’hui indispensable de maîtriser la fiabilité de ses produits. Une voie pour estimer et valider la fiabilité de manière efficace est d’analyser des mesures de dégradation caractéristique des phénomènes de défaillance. Ce domaine est en plein essor et il existe de nombreuses méthodes répondant à cette problématique. L’objectif de ces travaux de recherche est de proposer une méthodologie d’estimation de la fiabilité basée sur l’analyse de mesures de dégradation dans un contexte où peu de mesures sont disponibles, les temps d’essai sont réduits, les phénomènes physiques de dégradation sont complexes (usure, fissuration, fluage, corrosion) et les profils de mission sont multifactoriels. La première partie de ce travail concerne l’analyse des méthodes utilisées dans l’entreprise Renault. La deuxième partie est l’étude des méthodes présentes dans la littérature, qui répondent également à la problématique. Ensuite une méthodologie de comparaison de ces méthodes est proposée et permet de choisir la méthode d’estimation de fiabilité la plus adaptée aux différentes données représentatives des phénomènes physiques étudiés.

Full textAbstract:
La diversité des problèmes d’agencement a donné naissance à une multitude de travaux et d’applications liés à des domaines différents tels que la conception mécanique, l’urbanisme, l’aménagement d’intérieur, etc. . La résolution des problèmes d’agencement est généralement basée sur le savoir faire et l’expérience des concepteurs et repose sur un processus coûteux et long qui ne répond pas toujours à l’ensemble des contraintes du problème. En outre, dans la plupart des cas, l’agencement est effectué de manière manuelle à l’aide de plans ou des maquettes éventuellement à l’échelle. Dans les cas où des maquettes numériques sont utilisées, peu voir aucune assistance n’est proposée pour aider les concepteurs dans la prise de décision et la réalisation des tâches. Ce travail de thèse repose sur une démarche innovante impliquant une approche interactive générique basée sur l’utilisation conjointe d’outils de formulation et de résolution issus de la programmation par contraintes, et de techniques de réalité virtuelle (visualisation, immersion, et interaction 3D). L’approche proposée offre différents niveaux d’assistance et supporte la prise compte de diverses contraintes. Elle permet également de définir et de résoudre un problème d’agencement complexe de manière automatique. Les assistances offertes permettent de guider le concepteur vers des solutions viables et de prendre en compte ses préférences. Notre approche a été validée à travers différentes expérimentations impliquant la réalisation de tâches d’agencement en environnements virtuels. L’objectif était d’analyser la pertinence de l’approche proposée à travers l’étude de la performance humaine, et d’illustrer les possibilités d’interaction entre l’utilisateur et le système développé. Notre approche est actuellement étendue à différents cas applicatifs impliquant une problématique d’agencement<br>The diversity of layout problems gave rise to a several applications and related works in different areas such as mechanical design, urban planning, interior design, etc. . Solving layout problems is generally based on the designers expertise and involves a costly and tedious process that do not always satisfies the all problem’s constraints. In most cases, the layout is manually carried out using maps or a mock-ups. In cases where numerical mock-ups are used, no assistance is provided to help users in decision making and during the layout tasks. This manuscript proposes an interactive and generic approach based on the use of formulation and resolution tools from constraint programming, and virtual reality techniques (visualization, immersion and 3D interaction). The proposed approach provides different levels of assistance and supports several kinds of constraints. It also allows to define and automatically solve complex layouts. The various provided assistances can guide the user to possible solutions and take into account his/her preferences. Our approach has been validated through several experiments involving various layout tasks in virtual environments. The objectives were to analyze the relevance of the proposed approach through the study of human performance, and to illustrate the possibilities of interaction between the user and the developed system

Full textAbstract:
S’inscrivant dans le cadre de l’identification paramétrique, les travaux présentés dans ce manuscrit ont pour but de résoudre des problèmes inverses tridimensionnels de la conduction de chaleur (PICC-3D). Diverses situations thermiques sont traitées : identification du flux de chauffe délivré par une source fixe ou mobile, estimation des coordonnées de centre de deux sources de chauffe fixes, identification des coordonnées de centre d’une ou plusieurs sources fixes en temps réduit, estimation simultanée de la position et du flux de chauffe d’une source fixe, identification de la trajectoire d’une source mobile et estimation simultanée de la trajectoire et de l’intensité du flux d’une source de chauffe mobile. Une difficulté essentielle réside en ce que de tels problèmes inverses de conduction de la chaleur (décrits par un système d’équations aux dérivées partielles non linéaires) sont mal posés au sens d’Hadamard. Considérant les mesures de température fournies par un nombre limité de capteurs placés sur une frontière différente de celle où les sources de chauffe interviennent, ces PICC-3D ont été résolus avec succès par la mise en œuvre d’une méthode de régularisation itérative du gradient conjugué (MGC). La robustesse de la méthode est illustrée en considérant des bruits de mesure réalistes. En outre, un dispositif expérimental a été utilisé afin de mesurer l’évolution du champ de températures dans une plaque soumise à une source chauffante immobile. Les expérimentations réalisées attestent de l’intérêt de la MGC dans le contexte proposé<br>In the context of parametric identification, the work presented in this manuscript is devoted to inverse heat conduction problem resolution in three-dimensional geometries (IHCP-3D). The main objective of the resolution deals with identification of one or more unknown parameters in various situations such as: heat flux identification of a fixed (or mobile source), localization of two fixed heating sources, localizations in minimal time (for one or several heating sources), simultaneous determination of time-varying heat flux and location of a fixed source, mobile source trajectory identification, simultaneous estimation of strength heat flux and source mobile trajectory in a three-dimensional domain. Such an inverse heat conduction problem (described by a set of partial differential equations) is ill-posed in Hadamard’s sense. Considering the measured temperature provided by few sensors (located on a different face from that on which sources heat), IHCP-3D were successfully solved and the unknown parameters are identified considering the implementation of an iterative regularization method: the conjugate gradient method (CGM). The robustness of the proposed identification method is illustrated considering realistic disturbances. Moreover, an experimental bench is used in order to validate the robustness of the CGM in real context

Full textAbstract:
L'altération de la microcirculation sanguine est une anomalie fréquente retrouvée chez les sujets atteints de diabète, d'artérosclérose ou de phénomène de Raynaud. La fluxmétrie laser Doppler (FLD) est alors couramment utilisée pour le suivi de la perfusion microvasculaire en continu. Cependant, la dépendance du signal de FLD par rapport à l'architecture microvasculaire n'est pas encore bien connue. Nous avons donc développé le prototype d'un nouvel appareil de FLD. Ce prototype possède trois diodes laser de longueurs d'onde différentes (635 nm, 785 nm et 830 nm). Les photons de ces sources lumineuses sont transportés jusqu'à la zone cutanée d'étude grâce à une fibre optique. Les photons rétrodiffusés sont récupérés et guidés vers les photodétecteurs à l'aide d'autres fibres optiques distantes de 0,14 mm, 0,25 mm et 1,2 mm de la fibre optique émettrice. Des tests de validation de ce prototype ont été réalisés in vitro sur un fantôme et in vivo sur l'avant-bras et la paume de la main de sujets sains. Des simulations par la méthode de Monte Carlo ont également été réalisées dans le but d'étudier l'influence des longueurs d'onde et des distances entre la fibre optique d'émission et les fibres optiques de réception, sur les signaux acquis sur le fantôme et la peau. Les résultats montrent que la profondeur moyenne de pénétration des photons rétrodiffusés augmente avec la longueur d'onde et la distance entre les fibres. Le prototype permet donc de sonder les tissus à différentes profondeurs. Par ailleurs, en ce qui concerne le fantôme, le premier moment du spectre du photocourant augmente avec la vitesse et la concentration des diffuseurs, ainsi qu'avec la longueur d'onde et la distance entre les fibres. Les résultats obtenus avec le prototype ont ensuite été comparés avec ceux donnés par le fluxmètre Periflux 5000 commercialisé par la société Perimed. Les résultats obtenus avec le prototype sont similaires aux résultats obtenus avec le Periflux 5000. Ces travaux sont le fruit d'une collaboration entre le laboratoire Instrumentation et Électronique de l'université de Coimbra au Portugal, le Laboratoire d'Ingénierie des Systèmes Automatisés (LISA) de l'université d'Angers, et Frits de Mul, chercheur hollandais<br>Altered blood microcirculation is a common abnormality found in subjects with diabetes, arteriosclerosis or Raynaud's disease. Laser Doppler Flow Metering (FLD) is then commonly used for continuous monitoring of microvascular infusion. However, the dependence of the FLD signal on microvascular architecture is not yet well known. We have therefore developed the prototype of a new FLD device. This prototype has three laser diodes of different wavelengths (635 nm, 785 nm and 830 nm). The photons from these light sources are transported to the study skin area via an optical fibre. The backscattered photons are recovered and guided to the photodetectors using other optical fibres spaced 0. 14 mm, 0. 25 mm and 1. 2 mm from the emitting optical fibre. Validation tests of this prototype were performed in vitro on a ghost and in vivo on the forearm and palm of the hand of healthy subjects. Monte Carlo simulations were also carried out to study the influence of wavelengths and distances between the transmitting and receiving optical fibres on the signals acquired on the phantom and skin. The results show that the average penetration depth of backscattered photons increases with wavelength and distance between the fibers. The prototype therefore makes it possible to probe tissues at different depths. In addition, for the phantom, the first moment of the photocurrent spectrum increases with the speed and concentration of the diffusers, as well as with the wavelength and distance between the fibres. The results obtained with the prototype were then compared with those obtained with the Periflux 5000 flowmeter marketed by Perimed. The results obtained with the prototype are similar to those obtained with the Periflux 5000, and are the result of a collaboration between the Instrumentation and Electronics Laboratory of the University of Coimbra in Portugal, the Laboratory of Automated Systems Engineering (LISA) of the University of Angers, and Frits de Mul, Dutch researcher

Previous issue date: 2009-07-10<br>Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior<br>This thesis aims to enable a wider comprehension on thought operation as well as suggest alternatives for the formation of reflexive, critical, autonomous and creative individuals. The research defends the idea that it is possible for an individual to develop vigilant attention that makes thought flexibilization and change in the course of action, possible. This operation is called Internal Dialogue and is essentially characterized by a continuous openness towards novelty and learning. This makes it possible to minimize the usual way thought operates, in a automatic fashion (automatism). The research was based on theoretical references and ideas of David Bohm (1989;1994;2005) and Michael Polanyi (1983). The main emphasis was the understanding that a crisis situation enables awareness and state of alert that favors a more flexible thought pattern (Arag?o Gomes, 1994, 1997). The methodology used was presentation and analysis of these moments through autobibliographical records with indication of crisis on behalf of the subjects. Other criteria were also used that enabled the composition of the analyzed material such as the fact that: the subjects were public and real, the data was available through accessible material; the subjects identified themselves as in crisis; these crisis were of varied kinds; they had different social, cultural and professional profiles. Thus, three auto-bibliographical elements were selected: the Infidel: the story of a woman that challenged Islam (2007), written by the political Muslim author Ayaan Hirsi; Still me: memories (2001), of the actor Christopher Reeve as well as Confessions of a Philosopher (2001), by the philosopher Bryan Magee. In these books an analysis was made related to parts that stated action an though operation that express internal dialogue. These were organized into categories that were pointed out as relevant for the identification of internal dialogue such as: Perceptions of physical reaction; emotions, beliefs and issues, individual actions, self judgment and thought, self questioning, comprehension, observation and empirical investigation, perception of the changes they performed in the world, escape of conditioning as well as action that resulted in new meaning. The analysis performed reinforces our goal once it sated that internal dialogue is an important tool that allows thought awareness, minimizing common automatism and making consciousness possible as well as favoring the occurrence of critical and reflexive thought. Thus, final considerations deal with the need for the development of teaching methodologies that address internal dialogue as a counterpoint to the many daily action that reinforce the automatism of thought<br>Esta tese tem como objetivo permitir maior compreens?o sobre a opera??o do pensamento e sugerir alternativas para a forma??o de indiv?duos reflexivos, cr?ticos, aut?nomos e criativos.

Denominada Di?logo Interno, esta opera??o caracteriza-se essencialmente pela abertura ao novo e cont?nua disposi??o para o aprendizado, minimizando o modo como o pensamento opera, na maior parte do tempo (automatismo). Este estudo teve como principais refer?ncias te?ricas as id?ias de David Bohm (1989;1994;2005) e Michael Polanyi (1983) e como pressuposto fundamental o entendimento de que situa??es de crise propiciam momentos de tomadas de ci?ncia e estado de alerta que favorecem o pensamento a operar de modo mais flex?vel. (Arag?o Gomes, 1994, 1997). Metodologicamente, optamos por apresentar e analisar estes momentos atrav?s de relatos autobiogr?ficos, cujo autor indicava vivenciar momentos de crise. Outros crit?rios foram utilizados para comporem o material a ser analisado: tratava-se de pessoas reais e p?blicas; os relatos estavam dispon?veis em obras de f?cil acesso; tratava-se de pessoas em situa??o de crise por elas identificadas; apresentavam situa??es de crise de naturezas distintas; eram pessoas com perfis s?cio-culturais, profissionais e de g?nero distintos. Assim, foram selecionados tr?s relatos autobiogr?ficos: Infiel: a hist?ria de uma mulher que desafiou o Isl? (2007), da escritora e pol?tica mu?ulmana Ayaan Hirsi; Ainda sou eu: mem?rias (2001), do ator Christopher Reeve e; Confiss?es de um fil?sofo (2001), do fil?sofo Bryan Magee. Nestas obras foram analisados diversos trechos nos quais identificamos opera??es e a??es de pensamento que expressam tra?os do Di?logo Interno, organizadas nas categorias que identificamos como relevantes para a identifica??o do Di?logo Interno: percep??o de rea??es f?sicas, percep??o dos pr?prios sentimentos, percep??o das pr?prias cren?as e pressupostos, percep??o das pr?prias a??es, percep??o e julgamento do pr?prio pensamento, a??o de questionamento, busca da compreens?o, observa??o e investiga??o emp?rica, percep??o de sua mudan?a de a??o no mundo, sa?da do condicionamento e a??o de ressignifica??o.

Dessa forma, as considera??es finais desta tese apontam para a necessidade do desenvolvimento de metodologias de ensino que contemplem o Di?logo Interno como contraponto ?s diversas viv?ncias cotidianas que refor?am o automatismo do pensamento e a??o

Full textAbstract:
The latest generation of semiconductor wafer fabs produce Integrated Circuits (ICs) on silicon wafers of 300mm diameter. In this dissertation, we address the following two types of (new) scheduling problems that are encountered in this generation of wafer fabs: multiple-lots-per-carrier scheduling problem (MLCSP) and integrated automated material handling and lot scheduling problem (IMHLSP). We consider several variations of the MLCSP depending upon the number of machines used, the prevailing processing technology of the machines, and the type of objective functions involved. For the IMHLSP, we study two instances, one with infinite number of vehicles and the other with finite number of vehicles.
We begin by introducing a single-machine, multiple-lots-per-carrier with single-wafer-processing-technology scheduling problem for the objective of minimizing the total completion time (MLCSP1). The wafer carrier is a front-opening unified pod (FOUP) that can hold a limited number of wafers. The problem is easy to solve when all the lots are of the same size. For the case of different lot sizes, we first relax the carrier (FOUP) capacity and propose a dynamic programming-based algorithm, called RelaxFOUP-DP, which enables a quick determination of its optimal solution that serves as a lower bound for the problem with limited FOUP capacity. Then, a branch-and-bound algorithm, designated as MLCSP1-B&B, is developed that relies on the lower bound determined by the RelaxFOUP-DP algorithm. Numerical tests indicate that MLCSP1-B&B finds optimal solutions much faster than the direct solution of the MLCSP1 model by the AMPL CPLEX 10.1 Solver. In fact, for the medium and low density problems, the MLCSP1-B&B algorithm finds optimal solutions at the starting node (node zero) itself.
Next, we consider a single-machine, multiple-lots-per-carrier with single-carrier-processing-technology scheduling problem for the objective of minimizing total completion time (MLCSP2). As for the case of MLCSP1, the optimal solution for the case in which all the lots are of the same size can be obtained easily. For the case of different lot sizes, we determine a lower bound and an upper bound for the problem and prove the worst-case ratios for them.
Subsequently we analyze a two-machine flow shop, multiple-lots-per-carrier with single-wafer-processing-technology scheduling problem for the objective of minimizing the makespan (MLCSP3). We first consider a relaxed version of this problem, and transform the original problem to a two-machine flow shop lot streaming problem. Then, we propose algorithms to find the optimal capacitated sublot sizes for the case of lots with (1) the same ratio of processing times, and, (2) different ratios of processing times on the machines. Since the optimal solutions obtained from the lot streaming problem may not be feasible to the MLCSP3, we develop heuristic methods based on the heuristic procedures for the bin packing problem. We develop four heuristic procedures for lots with the same ratio of processing times, and another four procedures for lots with different ratios of processing times on the machines. Results of our numerical experimentation are presented that show that our heuristic procedures generate almost optimal solutions in a matter of a few seconds.
Next, we address the integrated automated material handling and lot scheduling problem (IMHLSP) in the presence of infinite number of vehicles. We, first, propose a new strong hybrid model, which has the advantages of both segregate and direct models. In the segregate model, a job is always transferred to the stocker after its completion at a station, while in the direct model, it is transferred to the next machine in case that machine can accommodate the jobs; otherwise, the job will stay at current station. The decisions involved in the strong hybrid model are the sequence in which to process the lots and a selection between the segregate and direct models for each lot, whichever optimizes system performance. We show that, under certain conditions about the processing times of the lots, the problem can be approximated by the cases of either infinite buffer or zero-buffer at the machines. Hence, we consider all three cases of the IMHLSP in this chapter, namely, infinite buffer, zero-buffer, and limited buffer sizes. For the strong hybrid model with limited buffer size, we propose a branch-and-bound algorithm, which uses a modified Johnson's algorithm to determine a lower bound. Two upper bounds for this algorithm are also determined. Results of our numerical investigation indicate that our algorithm finds optimal solutions faster than the direct solution of the IMHLSP model by the AMPL CPLEX 10.1 Solver. Experimental results also indicate that for the same problem size, the times required to solve the IMHLSP model with interbay movements are larger than those for intrabay movements.
Finally, we investigate the IMHLSP in the presence of limited number of vehicles. Due to the complex nature of the underlying problem, we analyze small-size versions of this problem and develop algorithms for their solution. For some of these problems, we can find optimal solutions in polynomial time. Also, based on our analysis on small-size systems, we have shown why some real-time dispatching (RTD) rules used in real fabs are expected to perform well while not the others. In addition, we also propose some new and promising RTD rules based on our study.<br>Ph. D.

The thesis consists of two parts. The first part provides basic theory on fractals. It begins with a simple explanation of what a fractal is using examples of self-similarity and recursive process and going into a more mathematical definition of fractals, introduced by B. Mandelbrot. After a brief history of fractals, a more in-depth analysis of Mandelbrot and Julia sets, the two well-known fractals arising from very simple sequences of complex numbers defined by the relation z_{n+1} = z_n^2 + c is given. The last chapter of the first part points out the reasons how fractals are useful and why they should be taught at school – fractals are fun; fractals are beautiful; anyone can play with them; fractals promote curiosity; computers, when used to explain fractal theory, enhance learning. The second part focuses on using Logo to generate fractals. It provides a few Logo programs of various complexity ranging from simple recursive functions to handling operations with complex numbers. Examples of Logo programs include generation of fractal trees, Koch snowflake and Sierpinski gasket, implementation of chaos game and iterated function systems, and manipulating complex numbers...

Previous issue date: 2012-03-26<br>Introduction: As a chronic disease which is highly prevalent, epilepsy has an important impact on the affected person's psychic/cognitive functioning and their family and social relationships. Among refractory epilepsies, epilepsy of the temporal lobe (ETL) is the most frequent in adults. Studies about lesions on the hippocampus and their effects found that patients with ETL presented verbal and visual memory deficits, depending on the affected hemisphere. Refractoriness to clinical treatment leads to the recommendation of surgery when it is seen that up to that point there have not been any other therapeutic alternatives available. In this context, there is a glimpse of a new treatment possibility for refractory epilepsies, using stem cells. These present a large capacity for proliferation and auto-renovation and the capacity to respond to external stimuli and give rise to different, more specialized cell lines. Objectives: To evaluate the effect of autologous stem cell transplants of bone marrow on the memory functions of patients with refractory epilepsy of the mesial temporal lobe. Patients and Methods: The selection of patients was done at the Outpatient Center for Clinical Epilepsy Research at PUCRS S?o Lucas Hospital [Ambulat?rio de Pesquisa Cl?nica em Epilepsia do Hospital S?o Lucas da PUCRS]. The 13 patients submitted themselves to therapy, and they were evaluated before and after the stem cell treatment (3 and 6 months after). The tests utilized for neuropsychological evaluation (pre and post-therapy) include the Wechsler Memory Scale revised (WMS-R), the Rey Auditory Verbal Learning Test (RAVLT) and the Taylor Complex Figure. Results and Conclusions: The results indicate a significant increase in the neuropsychological scores over time. In six out of seven utilized tests, the increase of average score obtained was significant. In only one test (visual reproduction I WMS R), the increase showed limitrofe statistical significance (between 5% and 10%). Given the favorable evolution of those patients analyzed, the stem cell transplant showed itself to be feasible, safe and with important perspectives for rehabilitation as well as psychosocial and professional reinsertion.<br>Introdu??o: A epilepsia, enquanto condi??o cr?nica de alta preval?ncia tem impacto importante no funcionamento ps?quico/cognitivo e nas rela??es familiares e sociais da pessoa acometida. Entre as epilepsias refrat?rias, a epilepsia do lobo temporal (ELT) ? a mais freq?ente em adultos. Estudos sobre les?es no hipocampo e seus efeitos, constataram que pacientes com ELT apresentam d?ficits de mem?ria verbal e visual, dependendo do hemisf?rio acometido. A refratariedade ao tratamento cl?nico, leva ? indica??o cir?rgica, visto que at? o momento, n?o est?o dispon?veis outras alternativas terap?uticas. Neste contexto, se vislumbra uma nova possibilidade de tratamento para as epilepsias refrat?rias, utilizando-se c?lulas-tronco (CT). Estas apresentam grande capacidade de prolifera??o e auto-renova??o e capacidade de responder a est?mulos externos dando origem a diferentes linhagens celulares mais especializadas. Objetivos: Avaliar o efeito do transplante aut?logo de c?lulas-tronco da medula ?ssea (CTMO) nas fun??es de mem?ria de pacientes com epilepsia refrat?ria do lobo temporal mesial. Pacientes e M?todos: A sele??o dos pacientes foi realizada no Ambulat?rio de Pesquisa Cl?nica em Epilepsia do Hospital S?o Lucas da PUCRS. Os 13 pacientes que se submeteram ? terapia, foram avaliados antes e ap?s o tratamento com c?lulas-tronco (3 meses e 6 meses depois). Os testes utilizados para avalia??o neuropsicol?gica: Escala de Mem?ria Wechsler-revisada (WMS-R), Teste de Aprendizado de Mem?ria Verbal de Rey (RAVLT) e Figura Complexa de Taylor. Resultados e Conclus?es: Os resultados indicam um aumento significativo nos escores neuropsicol?gicos ao longo do tempo. Em seis dos sete testes utilizados, o acr?scimo no escore m?dio obtido foi significativo e, em apenas um teste (WMS R visual imediato), o acr?scimo apresentou signific?ncia estat?stica lim?trofe (entre 5% e 10%). Dada a evolu??o favor?vel dos pacientes analisados, o transplante de CTMO mostrou-se fact?vel, seguro e com perspectivas importantes para a reabilita??o e reinser??o psicossocial e profissional.

L'elaborato, dopo aver elencato sommariamente i principali punti cardine della cosmologia, come le equazioni di Friedmann e le tipologie di modelli, si dedica alla descrizione dei parametri cosmologici.
Vengono trattati: Legge di Hubble, costante di Hubble, parametro di Hubble, parametro di espansione, parametro di curvatura, parametro di decelerazione, parametri di densità ed età dell'universo. Si fa riferimento ai metodi per calcolare il parametro di Hubble, dall'utilizzare il grafico di Hubble fino a confrontare i dati della CMB e di altre surveys, con relativi grafici. Si parla del modello critico e della densità critica, arrivando a definire il parametro di densità per la costante cosmologica, con i conseguenti casi per determinare il parametro di curvatura k. Viene trattata brevemente l'età dell'Universo e definito il parametro di decelerazione, con l'utilizzo delle supernovae di tipo Ia per calcolarlo, senza entrare però nei dettagli. In seguito viene presentato un excursus sulla CMB e in particolare sullo spettro di potenza angolare, concentrandosi sulle anisotropie della temperatura e dando una spiegazione fisica del grafico. Ci si occupa in seguito dell'impatto della densità di materia nello spettro di potenza, mostrando l'andamento del parametro di materia barionica e non barionica con i relativi grafici. Come ultima cosa, si utilizzano i risultati ottenuti dall'ultima missione Planck, VI, pubblicati nel 2018, per fornire la stima più aggiornata e veritiera dei parametri trattati. Vengono dati valori per: costante di Hubble, Densità di materia, Densità di energia oscura, Curvatura dell'Universo ed Età dell'Universo. Breve conclusione con riflessione sul modello Lambda-CDM.

Full textAbstract:
Il presente elaborato ha lo scopo di trattare il significato dei principali parametri cosmologici e di analizzare a fondo uno dei metodi con cui alcuni di questi sono ottenuti.
Inizialmente vengono discusse la curvatura dell'universo K, la legge di Hubble-Lemaître (da cui emerge il parametro di Hubble) e le equazioni di Friedmann dalle quali si ricavano i relativi modelli, che forniscono gli andamenti del fattore di scala a(t) per differenti fasi dell'universo. Essi sono utili per far emergere alcuni importanti parametri cosmologici: la densità delle differenti componenti dell'universo (radiazione, materia ed energia oscura) rapportata alla densità critica. In seguito viene trattato il modello Lambda-CDM, attualmente in vigore in cosmologia e vengono forniti i valori di alcuni parametri cosmologici misurati dal satellite Planck, analizzando per alcuni il metodo di determinazione. Viene quindi illustrata approfonditamente la radiazione cosmica di fondo, i suoi meccanismi primari di anisotropia, lo spettro di potenza angolare ed il suo utilizzo nella misurazione di alcuni parametri cosmologici.

In questa tesi si vogliono discutere in maniera generale alcuni parametri cosmologici
fondamentali. Nella prima parte si vedrà come si possono derivare analiticamente
le equazioni di Friedmann (sotto le opportune ipotesi di universo omogeneo e isotropo)
e come da esse si possono ricavare alcuni dei parametri più importanti. Si
presentano inoltre alcuni modelli di Universo e una breve introduzione al modello
CDM. Nella seconda sezione, introdotto il concetto di candele standard e di distanza
di luminosità, si vuole, tramite le Supernovae di Tipo Ia (rese candele standard
attraverso una opportuna "standardizzazione"), ricavare empiricamente i parametri
di densità di materia
m ed energia oscura e la costante di Hubble H0, e questo
sarà possibile mettendo in relazione il modulo di distanza ed il redshift cosmologico,
per vincolare i parametri cosmologici e riprodurre teoricamente una funzione
che approssima al meglio i dati osservativi. Si concluderà infine con considerazioni
riguardo le conclusioni derivate in merito.

In questa tesi si vuole fornire una descrizione generale dei principali parametri cosmologici e di come questi possano essere determinati attraverso osservazioni. In particolare saremo interessati alla natura dei parametri di densità, che hanno un ruolo fondamentale nella geometria dell'Universo, e al parametro di Hubble, che stabilisce una relazione lineare tra la distanza e la velocità di recessione, garantisce quindi una legge generale di espansione per l'Universo.

A presente dissertação trata dos romances Memória de Elefante, Os Cus de Judas e Conhecimento do Inferno do escritor português António Lobo Antunes. Para tal, a perspectiva assumida foi tentar entender as obras por parâmetros detectáveis nas mesmas e em outros meios pelos quais o autor dirige-se ao público como crônicas e entrevistas. Essa perspectiva permitiu destacar um aspecto essencial da obra do autor que a crítica em geral chama de uma certa tendência à autobiografia. Esse caráter autobiográfico não só é afirmado por Lobo Antunes como ele propõe sua expansão a todos os livros; só não se sabe se exclusivamente os literários ou não. A partir dessa expansão e de experimentações que algumas falas permitem é possível dissociar a idéia do autor estudado da idéia de autobiografia tradicionalmente demarcada que é estudada por Philippe Lejeune em Le Pacte Autobiographique. Além do que se torna aceitável dizer que, para o escritor português, autobiografia seria uma escrita que provasse a existência de um narrador. Baseando-se na hipótese de que Lobo Antunes deseja, de um modo geral, garantir sua existência e, desse modo, marcar a presença do humano no planeta, a dissertação buscou estabelecer uma outra autobiografia possível deste narrador a fim de destacá-lo e destacar o humano que ele expõe<br>This dissertation deals with the novels Memória de Elefante, Os Cus de Judas
and Conhecimento do Inferno from the portuguese writer António Lobo Antunes. To that end, the view taken was to try to understand the work by parameters detectables in the same and others ways by which the author turns to the public like chronicles and interviews. That prospect highlights an essential aspect in the work of the author, that criticism in general calls "a certain tendency toward autobiography." This autobiographical character is not only claimed by Lobo Antunes as he proposes to expand to all books, but it is not known whether only the literature, or not. From this expansion and experimentation that allowed by some discourses is possible to separate the idea of an author studied from the idea of autobiography traditionally demarcated this subject is studied by Philippe Lejeune in Le pacte Autobiographique. In addition to what is acceptable to say, for the portuguese writer, autobiography is a writing that would prove the existence of a narrator. Based on the hypothesis that Lobo Antunes want, in general, ensure their existence and thus mark the presence of humans on the planet, the dissertation sought to create another possible autobiography of this narrator to highlight it and the humans he explains

This thesis aims to investigate the reading and writing scene in António Lobo Antunes based on an analysis of his war letters, articles and of the episodes of the three novels that make up his autobiographical memory, Memória de elefante (1979), Os cus de Judas (1979), Conhecimento do inferno (1980). These texts show that reading and writing are ruled by a
reversibility and that they are not, therefore, distinct and independent processes in the author´s work. The complex war situation as scene and condition of production is implicated in his first novels and chronicles which, associated with the letters that brand that cycle, are an important research material in order to verify this reversibility. It is worth noted the urgency of a project (the books to come), the awakening of his endless work of observation and sieving of the reader Lobo Antunesmemory corroborating the composing of his writing. In this regard, the cultural references along his work that point out a reading scene ratified by his
writing (integrating that readers memory either as research topic for his literary project, or as an element for the elaboration of his work) will be investigated as well as it will be considered the construction of a virtual circular library. Based on this proposition and according to Walter Benjamin, it is argued that the term cultural reference can be taken as trace, vestige, trail of the presence of something that has already become absent.<br>Esta tese pretende investigar a cena da leitura e da escrita em António Lobo Antunes partindo da análise das cartas de guerra, das crônicas e de episódios dos três romances que compõem a guinada autobiográfica, Memória de elefante (1979), Os cus de Judas (1979),
Conhecimento do inferno (1980). Tais textos evidenciam que a leitura e a escrita são regidos por uma reversibilidade, não sendo, portanto, processos distintos e independentes na construção da obra do autor. A complexa situação da guerra como cenário e condição de produção está implicada nos romances iniciais e nas crônicas, que, conjugados com as cartas que marcam esse período, são um importante material de pesquisa para verificar essa reversibilidade. Percebe-se nesse material a urgência de um projeto (os livros por vir), o despertar do seu trabalho contínuo de observação e filtragem da memória do leitor Lobo Antunes a corroborar a composição de sua escrita. Nesse sentido, serão detidamente investigadas as referências culturais que atravessam sua obra e que indicam a cena da leitura ratificada pela escrita (integrando aquela memória, ora como objeto de pesquisa do seu projeto literário, ora como matéria de elaboração da obra), bem como será verificada, em seu diálogo com as outras artes, a construção de uma biblioteca circular virtual. A partir desse argumento e de acordo com Walter Benjamin, defende-se que o termo referência cultural possa ser tomado como traço, vestígio, rastro, da presença de algo que já se tornou ausente.

Full textAbstract:
LOTOS (Language Of Temporal Ordering Specification) is a Formal description Technique (FDT) based on the temporal ordering of observational behaviour. It was developed by ISO (International Organization for Standardization) for the specification of OSI (Open System Interconnection) services and protocols. This thesis presents a method of translating a LOTOS specification written in any given style into either of two simpler forms, known as the Monolithic Style Specification and the Parameterized Tree. A method of applying LOTOS expansion theorems to derive an intermediary form, known as the Behaviour Tree, is described first. A Reduction Algorithm, based on a subset of congruence rules, has been developed to provide a means to eliminate superfluous internal events and branches in the Behaviour Tree prior to conversion to either of the two simpler forms. Methods of transforming the reduced Behaviour Tree to either the Monolithic Style Specification ar Parameterized Tree have been developed. A tool has been developed to demonstrate these concepts. To show the application of this tool, we discuss a method for obtaining test cases from a Monolithic Style Specification. Finally, a method to translate such test cases into TTCN form has been outlined.

Timethreads are a new notation for visual description of the different causality paths of a system. They illustrate causality sequences of activities through systems. A design process based on the use of timethreads has already been defined. The Formal Description Technique LOTOS (Language Of Temporal Ordering Specification) is a specification language based on the temporal ordering of observational behaviour. This thesis aims at the integration of formal methods in the design of real-time and distributed systems by presenting a LOTOS interpretation of timethreads. With the help of a timethread grammar and a suite of techniques, LOTOS specifications are derived from timethread maps. The designer can then 'play' with the design by validating the specifications during the early stages of requirements capture and analysis.

Full textAbstract:
The dynamic behaviour of a LOTOS specification can be described as a tree, called behaviour tree, where the nodes represent the states of the behaviour, and the branches represent the possible next actions. Unfortunately, the behaviour tree for a realistic size LOTOS specification can be very large and often has no finite representation. This is the major limitation for the existing LOTOS verification techniques. The main goal of this thesis is to provide a new behaviour tree exploration technique, called Goal-Oriented Execution, that can be used to check properties of LOTOS specifications by narrowing exploration to a meaningfully selected subset of the tree. In this execution technique, the system derives traces (i.e paths in the behaviour tree) satisfying certain assertions that express temporal ordering of actions and data values properties. Goal-Oriented Execution is a combination of three techniques. The first technique is an automatically generated ADT evaluator/narrower engine. It is capable of evaluating an expression based on a rewriting rule approach, borrowed from functional programming, and deriving solutions to a set of constraints using a narrowing technique, borrowed from logic programming. The second technique is a static analyzer that determines where the given assertions are likely to hold, producing static information called static derivation paths. The third technique, called guided-inference system, involves a new type of inference rules that derive traces using static derivation paths to resolve most non-determinism. Implementation issues of this technique are also discussed, and examples of its usage are provided. The technique is now included in ELUDO, the University of Ottawa LOTOS interpreter.
