Full textAbstract:
Ce mémoire de thèse présente un environnement de programmation pour une cellule flexible d'assemblage multi-robots: SAFIR. Il comprend un mode hors-ligne qui correspond à l'interface opérateur (spécification des graphes d'assemblage contenant plusieurs plans d'assemblage d'un même produit; instanciation des bases de données concernant les pièces à assembler et les liaisons existant entre elles) et un mode en-ligne qui gère et supervise l'exécution des tâches d'assemblage de manière dynamique. L'objectif est de s'adapter, en temps réel, à l'évolution de la cellule (retard de pièces, pannes de ressources,. . . ). SAFIR utilise une approche distribuée des connaissances sur les pièces, les ressources, les tâches d'assemblage, etc. . . Son implémentation s'appuie sur les concepts de programmation orientée objet (encapsulation et niveau d'abstraction des données).

Full textAbstract:
This thesis presents a system which employs analogical reasoning to define and manipulate databases. The objective is to model the behavior of naive users who often adapt database relations and queries from documentation examples to the problem at hand. The user has at her disposal a manual that contains examples of database designs with a variety of database queries in some exemplary milieu called the base domain. The manual explains the example queries in simple terms and gives their implementation in a database query language such as SQL. Our user is not a database expert. She can neither define the database nor can she compose query implementations from scratch. At best she can construct simple queries in the base domain by copying them verbatim from the manual. Our system works in two steps: first it defines a target database by building incrementally analogies represented by pairs of object correspondences, base-target. These analogies are built by mapping objects, relationships, and semantic constructs from the base domain into the target domain. The process is then interactive and incremental (i.e. the user can accept or reject the inferred analogies). The second step of the approach consists to derive target domain query's implementation from its specification by reusing queries developed in the base domain. We rely on a weak form of derivational analogy--traces of a planner operating in the base domain are used to derive a target domain query's implementation in SQL from its specification. The very simple planner used builds in the base domain plans that result in particularly simple, prototypical queries. Queries are specified in a high level subset of natural language.

Le Système d'Aide à la Formation Interactive aux Réseaux SAFIR est un outil d'enseignement assisté en Téléinformatique. Il permet une formation pratique aux Protocoles de Communication dans le cadre de l'architecture normalisée ISO. Pour découvrir ce qu'est concrètement un protocole, l'étudiant est confronté à un simulateur qui tient lieu de système distant accessible à travers un service de communication. L'élève doit alors jouer le rôle d'un système local mettant en jeu le protocole d'interconnexion. L'analyse détaillée effectuée par le simulateur distant, émulant le protocole, permet de surveiller le travail de l'étudiant et de lui signaler clairement ses erreurs. Le système permet l'étude de tout protocole grâce à un noyau indépendant du protocole étudié travaillant sur une description du protocole introduite sous forme de structures de données et stockée sur fichiers. Nous avons défini les règles permettant l'implantation de nombreux protocoles, et la première application réalisée porte sur l'enseignement du protocole de transport ISO en classes 0 et 2.

Full textAbstract:
Multi-storey buildings with precast hollowcore concrete floor systems are very common in New Zealand and in many other countries, but the structural behaviour of such systems under fire exposure is not easy to predict because of the complex geometry, composite construction, and a wide range of possible support conditions. The 2006 version of the New Zealand Concrete Standard NZS3101 introduces new details for connection of hollowcore floor units to reinforced concrete supporting beams to improve seismic performance, but the fire performance of the new connection systems is unknown. Currently available methods for simulating fire performance of hollowcore slabs are not suitable for design purposes. Therefore, a simple yet sufficiently accurate simulation method needs to be developed. This study was carried out using a proposed simulation method to investigate the fire performance of hollowcore floor slabs with different connection details between the hollowcore units and their reinforced concrete supporting beams conforming to NZS3101. The proposed simulation method is examined on the platform of SAFIR, a non-linear finite element program that includes both thermal and structural analysis. The proposed simulation method was validated using available experimental results from a limited number of tests. It does not take account of shear and anchorage failures or spalling effects, so designers should consult other studies for this behaviour of hollowcore concrete flooring systems. By using the proposed simulation scheme in SAFIR, it is investigated whether the tensile membrane action established through beams parallel to the hollowcore units and different floor aspect ratios will enhance the fire resistance of hollowcore concrete flooring systems. From the simulation results it is concluded that rigid connections at both the ends and the sides of the hollowcore flooring systems to the supporting beams provide better fire resistance than rotationally flexible connections, and the fire resistance of hollowcore flooring systems can be increased by using stiffer supporting beams at the end of the slabs and also by decreasing the spacing between the beams parallel to the hollowcore units.

Full textAbstract:
En samverkanspelare drar nytta av interaktionen mellan det omslutande stålröret och profilens betongkärna för att därav erhålla en ökad lastkapacitet. För att förstå beteendet och effekterna av interaktionen mellan stål och betong är det viktigt att förstå de enskilda materialens beteende. Betongens huvudsakliga uppgift i en samverkanspelare är att ta upp tryckkrafter medan stålets främsta uppgift är att motverka momentpåkänning och uppta dragkrafter. I normal rumstemperatur samverkar stål och betong för att bära den aktuella lasten. Samverkanspelaren har stor potential med avseende på lastkapacitet. Nedan tas några av de förväntade positiva effekterna av interaktionen mellan stål och betong upp: Förekomsten av buckling för stålet försenas samtidigt som den försämrade bärförmågan efter lokal buckling uppstått dämpas, beroende på betongkärnans återhållande effekt. Förhindrar spjälkning och hållfasthetsnedsättningen för betongen blir inte lika drastisk. Ökad tryckhållfasthet och deformations kapacitet, speciellt för grövre tvärsnitt. Vid ett brandscenario utsätts pelaren för en temperaturhöjning. Värmeöverföringen från brandgaserna till pelaren sker främst genom strålnings- och konvektionsvärme. Lastkapaciteten för pelarens ingående material kommer att reduceras till följd av denna värmeökning. Storleken för reduceringen beror på hur hög temperatur materialen utsätts för, där en högre temperatur medför en kraftigare reducering. För den betongfyllda stålprofilen kommer således det omkringliggande stålet att fort bli mycket varmt medan betongkärnan erhåller en trögare temperaturökning. I brandfallets initialskede expanderar stålet hastigare än betongen, vilket medför att stålet då i princip bär hela den aktuella lasten. Efter en tid förmår inte stålet längre att vara lastbärare och betongkärnan bär då istället lasten. Pelarens slutliga kollaps sker först då betongkärnan slutligen inte förmår belastningen. En jämförande teoretisk undersökning av samverkans-, betong- och stålpelare under termisk påverkan genomfördes i detta arbete. Beräkningsgången följer de dimensioneringsregler som finns för respektive material i Eurocodes. Kapacitetsberäkningar är gjorda för både normal rumstemperatur likväl som för brandutsatthet. För analys och bestämning av pelartvärsnittens temperaturprofil vid de olika tidsstegen 30, 60 och 90 minuter användes ett nominellt brandförlopp. Tvärsnittens temperaturhistoria användes sedan för att reducera de mekaniska egenskaperna som funktion av temperaturen.Undersökningen konstaterade att samverkans- och betongpelarens kapacitet vid 60 minuters brandpåverkan var tillräcklig. Hand- och datorberäkningar påvisade nästintill likvärdig lastkapacitet vid termisk påverkan och normaltemperatur.A concrete-filled steel column is taking advantage of the interaction between the enclosing steel profile and the concrete core to obtain an increased load capacity. In order to understand the behavior and effects of the interaction between steel and concrete, it is important to first understand the individual material behavior. The main task of the concrete in a composite column is to absorb pressure forces while the steel's main task is to counteract stress and the tensile forces. At normal room temperature both steel and concrete interact to carry the current load. Concrete-filled steel column has a great potential according to load capacity. Some of the expected positive effects of the interaction between steel and concrete are: The occurrence of buckling for the steel is delayed and the strength deterioration after the local buckling is moderate, both due to the restraining effect of concrete. Prevents the concrete spalling and strength reduction of concrete core will not be as drastic. Increased compressive strength and deformation capacity, especially for large-diameter cross-section. In a fire scenario the column is exposed to a temperature increase. Heat transfer from the combustion gases to the column occurs mainly through radiation and convection heat. The load carrying capacity of the included materials will be reduced as a result of this heat transfer. The size of the reduction depends on how high temperature the materials are exposed to, where a higher temperature leads to a greater reduction. For the concrete-filled steel column, the surrounding steel profile will quickly become very hot while the concrete core obtains a slower rise in temperature. In the initial stage of the fire case the steel expands faster than the concrete, causing the steel to then basically carry the entire load of the column. After some time the steel will be incapable of carrying the load, then instead the concrete core will be the main load carrier. The final collapse of the column occurs only when the concrete core finally will be incapable to carry the load. A comparative theoretical study of concrete-filled steel column, concrete- and steel columns under thermal effects was carried out in this work. The calculation method followed the design rules that exist for each material in the Eurocode. Column capacity calculations are made for both normal room temperatures as well as for fire exposure. The ISO-standard fire curve was used for analysis and determination of each column cross-section temperature profile at the different time stages 30, 60 and 90 minutes. The mechanical properties were then reduced as a function of the temperature. The survey found that the composite and concrete column load capacity exposed to 60 minutes of the ISO-standard fire curve was adequate. Calculations made by hand and with computer showed almost equivalent load capacity by thermal effects and normal temperature.

In 21 century finned surfaces are used in almost all condensers to enhance their heat transfer capabilities. A lot of different models are presented in the literature: on horizontal and vertical finned tubes, inside finned tubes. The validation method of the theoretical models is based on comparison between measurement of average heat transfer coefficient and one calculated by the model. But in this case it is impossible to validate all approaches made in the theory.\

Full textAbstract:
L’objectif de cette thèse est d’étudier, à travers deux quotidiens libanais, An-Naharet As-Safir, les négociations de paix entre le Liban, la Syrie et Israël, de 1991 à 2000, période sensible de l’histoire contemporaine libanaise, phase d’après-guerre marquée par une forte influence politique syrienne sur le pays et intervalle stratégique quant au processus de paix lancé entre Israël et les pays arabes. Il s’agit d’analyser l’évolution de la couverture de ces deux quotidiens, représentatifs de la presse quotidienne nationale libanaise et des divergences politiques que connaît le pays dans le traitement d’un sujet géopolitique sensible qui touche à la souveraineté du Liban, ainsi qu’aux relations entre la Syrie et Israël. Pour ce faire, nous avons choisi un corpus qui couvre l’ensemble de la décennie, en se limitant à la Une de chaque journal. Afin de réaliser cette étude avec le recul scientifique nécessaire, nous avons mis au point un logiciel de tri spécialement conçu à cette fin. Il permet de mettre en place une grille d’organisation et d’analyse des informations textuelles et de la production médiatique.L’étude du corpus a été faite dans un premier temps de manière horizontale, afin de croiser les propos des différents acteurs et d’effectuer les mises en parallèle entre le traitement des deux quotidiens. Elle a ensuite été poursuivie de manière verticale, au sein de chaque journal et pour chaque auteur, dans le but de déterminer l’évolution des discours politiques et journalistiques retenus, tout en croisant les différents propos pour en faire ressortir les divergences et les convergences, ainsi que les constantes et les variantes au fil du tempsThe main purpose of this thesis is to study, peace negotiations between Lebanon,Syria and Israel from 1991 to 2000, via their coverage in two Lebanese news papers An-Naharand As-Safir. This was a tense period in the recent history of Lebanon; it was marked by thepolitical influence of Syria on Lebanon, and a strategic period during which the peace processbetween Israel and Arab countries began. It consists primarily in an analysis of the changingnature of the coverage and discourse of two major Lebanese daily newspapers - An-Nahar andAs-Safir. The “copy” here analyzed related to a sensitive geopolitical issue affecting Lebanese independence and relations between Syria and Israel. The survey spans à decade: it is limited to front-page coverage of each newspaper. In order to examine the subject scientifically, aspecific software was specially designed and developed for this purpose. A matrix fororganizing and analyzing textual information and media production was devised. First thestudy was affected horizontally, in order to compare various actors and their related newspaper coverage. Then the study was elaborated in a vertical manner, i.e. by handlingeach newspaper and each author separately, in order to establish the evolution of different discourse. This was achieved by cross-comparing differences and similarities in the discourse,and constants and variables over time

During years, the codes that regulate verifications against fire change a lot. They allow the use of engineering methods to approach problems by using Fire Safety Engineering. This thesis keeps in consideration the most recent fire prevention code (DM 16/10/2018) and highlights the difference between a compliant and an alternative solution for fire verification with a performance level III of a prestressed concrete warehouse with an ESFR shutdown system. To do it, has been done a comparison between the ISO 845 curve and a natural fire curve. For the natural fire case has been considered all the factors that influence the propagation or mitigation of the fire scenario (e.g. materials, fire load, ESFR system, type of activity and so on). Once do that, two FDS® simulations has been performed. The first one detects the ESFR time activation and the second has the aim to know time-temperature curves on load bearing elements through the implementation of the assumed final natural fire curve. Then, the behavior of the precast and prestressed concrete structure has been investigated, both with the ISO curve and the natural fire curve. In order to apply time-temperature curves in cross sections, some SAFIR® simulations has been done on the principal structural elements with both the fire curves. On the thinner cross section has been done also some hand-made verifications (from EC 1992-1-2). Then 2D and 3D mechanical analysis has been performed with SAFIR® considering the previous thermal mappings. The case analyzed with the ISO curve present wide displacements and the collapse of secondary beams, instead the case analyzed with the natural fire curve meets the requirements.

McGovern, Donna. "Salvinorin A: Fragment Synthesis and Modeling Studies." VCU Scholars Compass, 2009. http://scholarscompass.vcu.edu/etd/1862.
Full textAbstract:
Salvinorin A is a non-nitrogenous, selective kappa opioid receptor agonist with potent hallucinogenic properties. Because Salvinorin A has no basic nitrogen, it does not readily adhere to the “message-address” concept of selectivity for the opioid receptors. Therefore, a better understanding of how salvinorin A and its analogs interact with the kappa opioid receptor may shed some light on how salvinorin A obtains its potency and selectivity. The structure-affinity relationships (SAFIR) of salvinorin A and its analogs along with a discussion of the selectivity of the opioid receptors, is presented. A fragment of salvinorin A, methyl-3-acetoxy-4-oxocyclohexanecarboxylate, was synthesized to determine if the B, C and D rings are or are not necessary for binding to the opioid receptors. The fragment was found not to bind to the kappa, delta or mu receptor which reinforces the importance of the B, C and D rings in the binding of salvinorin A to the kappa opioid receptor. Homology models of the kappa, delta and mu opioid receptors were constructed based on inactive bovine rhodopsin, light-activated bovine rhodopsin and the human beta-2 adrenergic receptors. The program MODELLER was also used to construct the kappa opioid receptor. Two comparative molecular field analysis (CoMFA) studies are then presented which compared three different types of alignment methods. The alignment methods employed included a receptor-docked alignment in which the salvinorin A analogs were docked into a model of the kappa opioid receptor using the program GOLD. The docked poses for this alignment were chosen based on their similarity to our postulated model of salvinorin A in the kappa opioid receptor. In our model the furan oxygen forms hydrogen bonds with Q115(2.60) and Y320(7.43), the methoxy oxygen of the C-4 position ester group may form a hydrogen bond with Y312(7.35) and the methyl group of the C-2 position acetoxy moiety forms a hydrophobic interaction with Y313(7.36). These interactions are consistent with mutagenesis studies. The other alignment methods employed were a FlexS alignment and a realignment of the receptor-docked poses using the Fit Atoms function within SYBYL. Only the receptor-docked alignment method resulted in robust and predictive CoMFA models which indicates that the analogs may bind to the kappa opioid receptor in a similar but non-identical way. In addition, information from the CoMFA models based on the receptor-docked alignment led to a postulated binding mode for a set of amine analogs of salvinorin A which were not part of the original data set. Docking studies have the positively charged C-2 position amine group interacting with E209(XL2.49) while the furan oxygen and C-4 position ester group interacts with the same residues as in our model of salvinorin A in the kappa opioid receptor. The studies presented here not only support our postulated model of salvinorin A binding to the kappa opioid receptor but may also explain the trend of the beta epimers of the amine analogs to have a higher affinity than the corresponding alpha epimers. Site-directed mutagenesis studies could provide data to support or refute the postulated models of the amines docked in the kappa opioid receptor presented here.

Mestrado em Engenharia CivilNos dias que correm, a projeção de estruturas cada vez mais leves e resistentes, por razões de ordem económica e/ou estética, tem levado os engenheiros a elegerem a solução metálica como a solução estrutural mais eficiente. Os perfis de aço estrutural presentes na construção encontram-se em três formas: (i) perfis laminados a quente; (ii) perfis soldados; (iii) perfis enformados a frio. Os perfis enformados a frio têm como característica a reduzida espessura das paredes da secção transversal, possibilitando a ocorrência de fenómenos de instabilidade (local de placa, distorcional e global). Os fenómenos de instabilidade, para este tipo perfis, são modos de colapso. No caso de incêndio (elevadas temperaturas) estes fenómenos são intensificados. A presente dissertação tem como objetivo aumentar o conhecimento do comportamento estrutural dos perfis enformados a frio em situação de incêndio, nomeadamente madres (vigas de cobertura) de secção Z. Para isso, é elaborada uma simulação numérica, com base em análises numéricas não lineares da resistência ao fogo das madres, através do programa de elementos finitos SAFIR. Na presente análise é avaliada ainda a influência das imperfeições geométricas e imperfeições estruturais (tensões residuais) na resistência última das madres. Os resultados obtidos são comparados com as cargas últimas fornecidas pelas prescrições do Eurocódigo 3.
Nowadays, the design of increasingly lighter and stronger structures, for economic and/or aesthetic reasons, has led engineers to select metal structures as the most effective structural solution. One can find structural steel profiles in three ways: (i) hot rolled profiles; (ii) welded profiles; (iii) cold formed profiles. Cold-formed profiles are characterized by a reduced cross section wall thickness, allowing the occurrence of instability phenomena (local plate, distortional and global). For this profiles type, the instability phenomena is a collapse mode. In case of a fire (high temperature) this phenomena is intensified. This dissertation aims to increase the knowledge of the structural behavior of cold-formed profiles in case of a fire, in particular purlins (roof trusses) of Z section. For this study, a numerical simulation was developed, based on non-linear numerical analysis to obtain the ultimate fire resistance of beams, through the finite element program SAFIR. In the present analysis is also evaluated the influence of geometric and structural imperfections (residual stresses) on the ultimate strength of purlins. The obtained results are compared with the ultimate resistance provided by the requirements of Eurocode 3.

L’objectif principal de ce travail est l'étude de la planification de trajectoires pour les robots parallèles en prenant en considération les collisions et les singularités. Les développements ont été intégrés dans le logiciel SMAR du LMS. Ce logiciel, à l’origine limité aux robots sériels, a été enrichi en changeant sa structure pour permettre la modélisation et l’analyse des robots parallèles. Une étude des robots parallèles et des notions qui s'y rapportent, ainsi que les différentes structures de robots et les types de maillons et de liaisons qui les composent sont décrites. Les chaînes fermées sont modélisées à l’aide de différents types de contraintes entre maillons. Une méthode pour générer les équations du modèle cinématique en séparant les variables actives, passives et opérationnelles est présentée. Une méthode de planification de trajectoires permettant d’éviter les singularités et les collisions internes et externes est proposée. Cette méthode combine deux modes: un mode de recherche en profondeur et un mode de recherche en largeur. Un exemple de robot 3-RPR est traité pour illustrer les développements de cette méthode. Des résultats expérimentaux sont présentés pour valider le modèle. La première expérimentation est réalisée sur le robot translateur conçu au LGM Monastir et construit au L. M. S. La seconde expérience a été conduite à l’Université de Cassino sur un robot à câbles. Enfin, la dernière expérimentation est originale puisqu’elle a été menée sur un robot chien, qui a été traité comme un robot parallèle. Les résultats obtenus ont servi à valider les modèles développés dans la thèseThe main objective of this work is the analysis and the modeling of parallel robots. The problem of path planning avoiding collisions and singularities is studied. The software SMAR, developed in LMS, was used to implement the different algorithms. This software, initially limited to serial robots, was modified in order to cope with parallel robots. First, an analysis of the parallel structures and their different links and joints, is described. Closed kinematic chains are modeled using different types of geometry constraints, which led us to propose a method to generate automatically the kinematic model and separate the passive, active and operational parameters. Second, a method of path planning avoiding both singularities and collisions is proposed. This method combines two modes: a depth search mode and a width search mode. A 3-RPR example is given to illustrate the obtained results. The second part of this thesis presents some experiments to validate the proposed models. The first experiment used a translational robot designed in LGM Monastir and built in LMS. The second experiment was done at the University of Cassino on a 4-cable-driven-robot. The last experiment using a dog robot, showed how this type of structures can be treated as a parallel one. This approach turned out to be an effective way to control such complex structures in a simple and effective way

Full textAbstract:
Globally, approximately 1.2 million people die each year due to trac accidents. Upperextremity injuries account for 18% to 25% of all car accident injuries. In order to beable to analyze these crash-related injuries, Human body models(HBMs) are used as acomplement to FE simulations. An example of a HBM is the THUMS SAFER that isbased on a 50 percentile American male. The aim of this study was to improve the upperextremity of the THUMS SAFER with respect to Autoliv's requirements to better predictfractures. In addition, this was validated against the Forman experiment(Forman, et al.,The journal of trauma and acute care surgery, vol. 77, 2014) where human cadavers ofthe upper extremity were axially impacted to replicate a car collision. This was done bygenerating the upper extremity geometry with segmentation of medical images of a righthuman hand in combination with the complete STL-geometry of the forearm from thePiper project. The STL-geometry of the segmented human hand and Piper forearm wasintegrated and a complete STL-geometry of the upper extremity was obtained. Basedon the complete STL-geometry, the FE-arm HEX 4.0 was built with modelling of bones,ligaments, soft tissue and skin with corresponding material choice in accordance withAutoliv's requirements.The model HEX 4.0 was improved considering an increased mesh density from an averageof 94% to 98%. HEX 4.0 was also validated against the data from the Forman experimentfor experiments 5, 6 and 15. It showed a good correlation with the acceleration curvesbetween the simulated and experimental values for the three experiments. The reactionforce in the elbow was compared for experiment 15, where the simulated value 5.7 kNdivided by a factor of 1.4 from 4 kN for the experiment. Furthermore, the rst principalstrains that occurred in HEX 4.0 were analysed by 17 ms were the highest accelerationwas achieved for experiments 5 and 6. Both experiments were shown to be close to thefailure threshold of bones. However, the highest value 5=9.8E-03 occurred in the radiusfor experiment 5, while 6=9.3E-03 in a ligament for experiment 6. In addition, thefailure threshold for experiment 15 exceeded 5 ms in lunate, schapoid and triquetrum.This indication of fractures is in good agreement with the experimental results where thecorresponding bones resulted in fractures in experiment 15. HEX 4.0 was an improvedupper extremity of the THUMS SAFER considering an increased mesh density. It isalso capable of indicating fractures and corresponding positions in the form of analyzesof occurring stresses and strains. Nevertheless, improvements and further validation ofHEX 4.0 has been proposed in the future work section.Globalt, dör varje ar ungefär 1.2 miljoner personer på grund av trafikolyckor. Övre extremit skador utgör 18% till 25% av alla skador inom bilolyckor. För att kunna analysera dessa krockrelaterade skador används humanmodeller (HBM) som komplement för FE-simuleringar. Ett exempel på en HBM är THUMS SAFER som är baserad på en 50 percentile amerikans man. Målet med denna studie är att förbättra uppre extremiten av THUMS SAFER med avseende på Autolivs krav för att bättre kunna förutspå frakturer Dessutom validerades detta mot Forman experiment (Forman, et al., The journal of trauma and acute care surgery, vol. 77, 2014) där övre extremitet av människokadaver blev axiellt påverkade för att replikera en bil kollsion. Detta gjordes genom att generera STL-geometrin av den övre extremitet med segmentering av medicinska bilder av en höger människohand i kombination med färdig STL-geometri av underarmen från Piperprojektet STL-geometrin av den segmenterande människohanden och Piper underarmen integrerades och en komplett STL-geometri av övre extremiteten erhölls. Baserad på den kompletta STL-geometrin byggdes FE-armen HEX 4.0 med modellering av ben, ligament, mjukvävnad samt hud med motsvarande materialval i enighet med Autolivs krav. Modellen HEX 4.0 förbättrades i form av en ökad mesh densitet från medelvärdet 94% till 98%. Den validerades även gentemot data från Forman experimentet för experiment5, 6 och 15. Det påvisade en god korrelation på accelerations kurvorna mellan de simulerade och experimentella värdena för de tre experimenten. Reaktionskraften i armbågen jämfördes för experiment 15 där den simulerade värdet 5.7 kN skiljde sig med en faktor 1.4 från 4 kN för experimentet. Ytterligare analyserades första huvudtöjningarna som uppkom i HEX 4.0 vid 17 ms, då den högsta accelerationen uppnåddes för experiment 5 och 6. Det visades att båda experimenten låg nära failure tröskeln av ben, däremot uppkom den högsta värdet 5=9.8E-03 i radius för experiment 5, medan 6=9.3E-03 i ett ligament för experiment 6. Dessutom överskred failure tröskeln för experiment 15 efter 5 ms i lunate, schapoid och triquetrum.

Full textAbstract:
Operationell risk inom banksektorn är ett område under utveckling. Utredningen har behandlat ett ramverk för hantering av operationell risk kallat A Systemic Approach Framework for Operational Risk (SAFOR). Syftet har varit att konkretisera detta ramverk och inom detta utvärdera en metod kallad Damage Evaluation and Effective Prevention (DEEP-metoden) i kombination med ett datoriserat beslutsverktyg benämnt DecideIT. SAFOR hanterar operationell risk som är nära kopplat till företagets processer, personer och system. Dess utformning grundar sig i general system theory, en holistisk verksamhetssyn som minskar risken för överlappning mellan olika riskhanteringsområden. Ramverket är uppde-lat i fyra moduler som hanterar identifiering av risker och riskhanter-ingsstruktur, värdering av olika handlingsalternativ, hantering av riskmått och intervalluppskattningar. DEEP-metoden hanterar identifie-ring av risksituationen och rangordning av olika framtidscenarier. Beslutsverktyget DecideIT är en implementering av DELTA metoden som hanterar intervallskattningar av sannolikheter och värden tillsammans med känslighetsanalyser. Utredningen har genomförts genom litteratur-studie och eget test. Resultatet visar en ökning av ramverkets tillämp-barhet genom införandet av ett processperspektiv där en kartläggning av arbetsflödet visar att DEEP-metoden berör flera moduler inom ramverket. Vid närmare beaktan av ramverkets osäkerhetsmodul klargörs dess syfte till rangordning av alternativ för beslutstagande. Metod och beslutsverktyg inom osäkerhetsmodulen bör hantera osäker-heter, framtidscenarier och vara lättanvänt. Detta visar sig stämma för DEEP-metoden och DecideIT när tillämpbarhetstest utförs. SAFOR anses fungera som grund för helhetsförståelse. Ramverket kan sedan implementeras genom för verksamheten passande metod vilket ökar flexibiliteten mot olika typer av organisationer. Målen för studien anses vara uppfyllda. Fortsatt arbete finns i utformning av tydligare avgräns-ning mellan ramverkets moduler och testning av metoder inom dessa.The investigation deals with a framework named A Systemic Approach Framework for Operational Risk (SAFOR). The aim is to concretize SAFOR and Evaluate the proposed method of Damage Evaluation and Effective Prevention (DEEP) in combination with the decision tool DecideIT. SAFOR deals with operational risk which is linked to the company's processes, people and systems. The framework is based on a holistic approach, which reduces overlap in risk management and consists of four modules which deal with; identification of risk and risk manage-ment structure, risk-reducing alternatives, risk measurement and interval estimates. The DEEP-method handles Identification of risk and Evalua-tion of future scenarios. DecideIT implements the DELTA-method which handles interval assessments for probabilities and values together with Sensitivity Analysis. The investigation was by Literature Studies and a test. A process perspective is proposed to increase the applicability of SAFOR. It discovered that the DEEP-method intersects the framework´s modules. Investigation of the framework´s uncertainty module reveals its aim to sort decision alternatives and that the method and decision tool applied in it should deal with uncertainties, future scenarios and be easy to use. This proved to be true for the DEEP-method and DecideIT by a test. SAFOR is suited to be a source for understanding the whole-ness and various methods can be implemented inside the framework to increase flexibility. The objective of the study is achieved but there is a need for further effort with interfaces and Testing methods within the framework.

Full textAbstract:
Globally, approximately 1.2 million people die each year due to traffic accidents. Upper extremity injuries account for 18% to 25% of all car accident injuries. In order to be able to analyze these crash-related injuries, Human body models(HBMs) are used as a complement to FE simulations. An example of a HBM is the THUMS SAFER that is based on a 50 percentile American male. The aim of this study was to improve the upper extremity of the THUMS SAFER with respect to Autoliv's requirements to better predict fractures. In addition, this was validated against the Forman experiment(Forman, et al., The journal of trauma and acute care surgery, vol. 77, 2014) where human cadavers of the upper extremity were axially impacted to replicate a car collision. This was done by generating the upper extremity geometry with segmentation of medical images of a right human hand in combination with the complete STL-geometry of the forearm from the Piper project. The STL-geometry of the segmented human hand and Piper forearm was integrated and a complete STL-geometry of the upper extremity was obtained. Based on the complete STL-geometry, the FE-arm HEX 4.0 was built with modelling of bones, ligaments, soft tissue and skin with corresponding material choice in accordance with Autoliv's requirements. The model HEX 4.0 was improved considering an increased mesh density from an average of 94% to 98%. HEX 4.0 was also validated against the data from the Forman experiment for experiments 5, 6 and 15. It showed a good correlation with the acceleration curves between the simulated and experimental values for the three experiments. The reaction force in the elbow was compared for experiment 15, where the simulated value 5.7 kN divided by a factor of 1.4 from 4 kN for the experiment. Furthermore, the fi rst principal strains that occurred in HEX 4.0 were analysed by 17 ms were the highest acceleration was achieved for experiments 5 and 6. Both experiments were shown to be close to the failure threshold of bones. However, the highest value e5=9.8E-03 occurred in the radius for experiment 5, while e6=9.3E-03 in a ligament for experiment 6. In addition, the failure threshold for experiment 15 exceeded 5 ms in lunate, schapoid and triquetrum. This indication of fractures is in good agreement with the experimental results where the corresponding bones resulted in fractures in experiment 15. HEX 4.0 was an improved upper extremity of the THUMS SAFER considering an increased mesh density. It is also capable of indicating fractures and corresponding positions in the form of analyzes of occurring stresses and strains. Nevertheless, improvements and further validation of HEX 4.0 has been proposed in the future work section.Globalt, dör varje år ungefär 1.2 miljoner personer på grund av trafi kolyckor. Skador på övre extremitet utgör 18% till 25% av alla skador inom bilolyckor. För att kunna analysera dessa krockrelaterade skador används humanmodeller(HBM) som komplement för FE-simuleringar. Ett exempel på en HBM är THUMS SAFER som är baserad på en "50 percentile" amerikans man. Målet med denna studie är att förbättra över extremiten av THUMS SAFER med avseende på Autolivs krav för att bättre kunna förutspå frakturer. Dessutom validerades detta mot Forman experiment(Forman, et al., The journal of trauma and acute care surgery, vol. 77, 2014) där övre extremitet av människokadaver blev axiellt påverkade för att replikera en bilkollsion. Detta gjordes genom att generera STL-geometrin av en övre extremitet med segmentering av medicinska bilder av en höger människohand i kombination med färdig STL-geometri av underarmen från Piper projektet. STL-geometrin av den segmenterande människohanden och Piper underarmen integrerades och en komplett STL-geometri av övre extremiteten erhölls. Baserad på den kompletta STL-geometrin byggdes FE-armen HEX 4.0 med modellering av ben, ligament, mjukvävnad samt hud med motsvarande materialval i enighet med Autolivs krav. Modellen HEX 4.0 förbättrades i form av en ökad mesh densitet från medelvärdet 94% till 98%. Den validerades även gentemot data från Forman experimentet för experiment 5, 6 och 15. Det påvisade en god korrelation på accelerations kurvorna mellan de simulerade och experimentella värdena för de tre experimenten. Reaktionskraften i armbågen jämfördes för experiment 15 där den simulerade värdet 5.7 kN skiljde sig med en faktor 1.4 från 4 kN för experimentet. Ytterligare analyserades första huvudtöjningarna som uppkom i HEX 4.0 vid 17 ms, då den högsta accelerationen uppnådes för experiment 5 och 6. Det visades att båda experimenten låg nära gränsen för benfraktur, däremot uppkom det högsta värdet e5=9.8E-03 i radius för experiment 5, samt e6=9.3E-03 i ett ligament för experiment 6. Dessutom överskred gränsen för benfrakturer för experiment 15 efter 5 ms i lunate, schapoid och triquetrum. Denna indikation av frakturer stämmer väl med resultatet av experimentet där motsvarande benen resulterades i frakturer i experiment 15. HEX 4.0 är en förbättrad övre extremitet av THUMS SAFER i form av förbättrad meshdensitet. Den är även kapabel att indikera frakturer och motsvarande position i form av analyser på förekommande spänningar och töjningar.

Full textAbstract:
Studien är en källstudie vars syfte är att undersöka huruvida SARA B-SAFER fungerar som riskbedömningsinstrument och om brottsutvecklingen för våld mot kvinnor i nära relationer har ökat eller minskat under tidsperioden, åren 2000-2012. Urvalet för studien är Kalmar polismyndighet och Södertörn polismästardistrikt. Underlaget för studien är tidigare forskning från hur Polisen har arbetat med SARA B-SAFER och offentlig statistik på antalet anmälda brott från Brottsförebyggande rådet (BRÅ). Resultaten i studien visar på en ökning av antalet anmälda brott för våld mot kvinnor i nära relationer, samtidigt som anmälningarna ligger på en förhållandevis jämn nivå. Vidare indikerar studien på att det finns en komplexitet kring SARA B-SAFER som riskbedömnings-instrument, då det finns indikationer på att instrumentet har en prediktiv validitet. Åtgärder för att skydda brottsoffren hamnar i skymundan och SARA B-SAFER fungerar då inte preventivt, vilket kan förklara antalet ökade anmälningar för att instrumentet predicerar rätt.This study aims to appose if the SARA B-SAFER are successful as a risk-assessment tool and if the crime development for spousal against women have risen or declined between the years 2000-2012. Kalmar Police County and Södertörn Manor are participating and statistics over crimes for spousal violence against women are studied in these areas. The material for the study is earlier research and statistics from Brottförebyggande rådet (BRÅ). The result in the study show that the crimes for spousal violence against women have increased but lay on a stable level. Further there is a complexity about SARA as a risk-assessment tool, when it seems to work on a predictive level, but not as much on a preventive stage, as wishes. The predictive factor on SARA can explain the increased numbers of crimes.

Jameison, Gary. "Inventory estimation for inherently safer design." Thesis, Loughborough University, 2005. https://dspace.lboro.ac.uk/2134/35803.
Full textAbstract:
Traditional approaches to safety in process plants tend to rely on 'added-on' safety measures as a means of minimising risk. During the design process the first stage at which safety is considered in detail is the HAZOP study. Inherent safety, where safety is designed into a plant has been found to have great benefits with regards to both safety performance and operating costs. In order to implement inherent safety fully it must be considered as early as possible in the design process, before decisions have been made which are fixed and costly to change. The major barrier to this is the lack of data available in the early design stage, which prevents different options being assessed for safety. The most important variable is that of inventory, as the quantity of material present is a major factor in determining the hazard posed by that material. The use of short-cut design methods together with simplifying assumptions was investigated to determine if they could be used in an inventory estimation study. It was found that such methods could be used. Although there are uncertainties in the available data it would be possible to use the methods to estimate the inventory of a process at the route selection stage of the design study. This would enable the comparison of different process routes in order to select the route that is the safest in relation to hazardous inventories and also to pinpoint which areas of a process have the greatest effect on safety. This would aid the design engineer to focus on the most hazardous items in a process plant and minimise that hazard.

Desenvolvedores evoluem linhas de produtos de software (LPSs) manualmente ou usando Ferramentas típicas de refatoração de programas. No entanto, quando a evolução de uma Linha de produtos é feita para introduzir novas características, ou para melhorar o seu projeto, é importante ter a certeza de que o comportamento dos produtos existentes não é modificado. Programas típicos de refatoração de software não podem garantir isso porque o contexto de LPS vai além de código, e outros tipos de artefatos de código, e envolve artefatos adicionais, tais como modelos de feature e configuration knowledge. Além disso, em uma LPS, normalmente temos que lidar com um conjunto de possíveis artefatos de código-fonte alternativos que não constitui um programa bem formado. Como resultado, mudanças manuais e ferramentas de refatoração de software existentes podem introduzir mudanças comportamentais ou invalidar configurações de produtos existentes. Para evitar isso, propomos abordagens e implementamos ferramentas para tornar a evolução de linhas de produtos mais segura; essas ferramentas verificam se transformações em LPS são refinamentos no sentido de que preservam o comportamento dos produtos originais da LPS. Elas implementam aproximações diferentes e práticas de uma definição formal de refinamento de LPS. Avaliamos as abordagens em cenários concretos de evolução de LPS, onde o comportamento do produto existente deve ser preservado. No entanto, nossas ferramentas constataram que algumas transformações introduziram mudanças comportamentais. Além disso, avaliamos refinamentos defeituosos, e o conjunto de ferramentas detectou as mudanças de comportamento.

Esta dissertação teve por objeto delinear alguns fatores relativos ao processo de emergência da leitura dos trabalhos do linguista e antropólogo norte-americano Edward Sapir (1884-1939) como um dos proponentes de um conjunto de afirmações acerca da natureza das línguas naturais, agrupadas sob o rótulo relativismo linguístico, cujo debate recebeu bastante atenção dos antropólogos linguistas estadunidenses, na primeira metade do século XX. Costuma-se afirmar que o relativismo linguístico seja uma hipótese, que alega que a língua pode moldar a percepção da realidade, o pensamento ou a cultura. Visto o nome de Sapir estar associado ao de Whorf, como o rótulo hipótese Sapir-Whorf indica, e que este rótulo tem sido bastante utilizado atualmente para se referir ao relativismo linguístico, efetuou-se o rastreamento de alguns conceitos fundamentais nesta discussão, dentro do quadro teórico proposto por Sapir, tal como suas concepções acerca da língua, da cultura e do pensamento, com vistas a avaliar a procedência de sua recepção como um relativista. Havido sido este trabalho conduzido sob a metodologia da Historiografia Linguística, buscamos também resgatar os fatores contextuais nos quais tais proposições teóricas emanaram. Por fim, propomos a discussão da configuração do termo relativismo no horizonte teórico do autor, visando fornecer uma perspectiva de leitura diferente da proposta, atualmente, por inúmeros manuais de História da Linguística.This dissertation had as its objective to outline some factors related to the emergence process of reading the American anthropologist and linguist Edward Sapirs (1884- 1939) papers as one of the proponents of a set of assertions about the nature of natural languages, grouped under the label linguistic relativity, whose debate received much attention from American linguistic anthropologists, during the first half of the twentieth century. It is often said that the linguistic relativity is a hypothesis, which argues that language can shape the perception of reality, thought or culture. Since Sapirs name has been associated with Whorfs, as the label Sapir-Whorf hypothesis indicates, a term widely used today to refer to linguistic relativity, we carried out tracking of some fundamental concepts in this discussion, within the theoretical framework proposed by Sapir, as his conceptions of language, culture and thought, in order to assess the merits of its reception as a relativist. As this research was conducted under the methodology of Linguistic Historiography, we have also sought to rescue the contextual factors in which such theoretical propositions have emanated. Finally, we propose to discuss the setting of the term relativism in the author\'s theoretical horizon, aiming to provide a reading perspective fairly different from the ones proposed currently by numerous handbooks on the History of Linguistics.

Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?
In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires – most of them would have survived if there had been a functioning smoke detector.
Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing. The smoke detector has in these cases unfortunately been removed because of unwanted alarms in connection with e.g. cooking and therefore been disassembled and forgotten about. Another major problem is the lack of power supply to the smoke detector i.e. the batteries run out and have not been replaced by new ones. Therefore, the project team has put the focus in the users when developing a new smoke detector, Safire, in order to eliminate the causes of having a non-functioning smoke detector at home. Safire is a unique solution that combines high security with simple using. Additionally it has a pleasant design that favors overall impression and enhances safety.
Kan du garantera att din brandvarnare larmar om det börjar brinna inatt?
I 80 procent av de fall där räddningstjänsten rycker ut saknas det brandvarnare i bostaden där branden uppstått. År 2009 omkom 118 personer i Sverige i bränder – merparten av dem hade överlevt om det hade funnits en fungerande brandvarnare.
Tidigare utveckling av brandvarnare har främst inriktats på att förbättra de komponenter som känner av rök och larmar vid brand. Men i de flesta fall har inte problemet legat i huruvida brandvarnaren fungerat eller inte som färdigmonterad, utan snarare att den inte funnits på plats alls. Brandvarnaren har i dessa fall tyvärr övergått till att bli ett irritationsobjekt då den exempelvis har reagerat på oset vid matlagning, tjutit och monterats ned, för att sedan falla bort i glömskan. Ett annat stort problem är att det saknas strömförsörjning till brandvarnaren; batterierna tar slut och man glömmer att sätta i nya.
Därför har projektgruppen arbetat med användaren i fokus vid utvecklingen av en ny brandvarnare, Safire, för att eliminera orsakerna till att man har en icke fungerande brandvarnare i bostaden. Safire är en unik lösning som kombinerar hög säkerhet med enkelt användande. Dessutom har den en snygg design som gynnar helhetsintrycket och förstärker säkerheten.

As more of the world moves towards online technologies, users are exposed to the increasing threat of cyberattacks. Studies show that most of these attacks begin with a phishing attack. Phishing emails and websites may compromise user credentials or download unsolicited and malicious software. This thesis presents the design and implementation of Quboid, a workstation for safer web interaction. Quboid helps users better defend against phishing attacks by providing several security mechanisms. The design of Quboid is based on the principle of isolation and restricted communication. The system enforces isolation by using virtualization to restrict browser instances to show dierent websites in separate virtual machines. For example, Quboid isolates a user's bank website and social networking website in separate VMs. It uses deep-packet inspection to implement a HTTP/HTTPS proxy filter to ensure virtual machines only communicate with specfic web servers. It also provides users with a secure interface and provides cues to help them recognize phishing attacks.

Resumo: o diamante possui um conjunto único de propriedades desejáveis para uma grande variedade de aplicações na eletrônica, áptica, química, mecânica, etc.O potencial de aplicações possíveis do diamante tem aumentado consideravelmente devido ao desenvolvimento de técnicas para a síntese de filmes cristalinos de diamante a baixas pressões a partir de misturas de gases com metano, acetileno, e outros hidrocarbonetos. Para poder atingir toda a potencialidade do diamante é preciso entre outras coisas, obter o crescimento dos cristais de diamante sobre diferentes tipos de substrato de uma maneira economicamente viável. Este trabalho resume nossos resultados experimentais no crescimento de filmes de diamante sobre substratos de safira, empregando comparativamente como fonte de carbono tanto o metano quanto misturas de etanol e acetona. A técnica de crescimento utilizada foi o método da deposição química a partir da fase de vapor assistida por filamento quente(HFCVD). Foram encontradas condições de crescimento de filmes de diamante sobre safira, pressão de 100 a 120 Torr, temperatura do substrato de 500 a 650°C e fluxo do gás reagente entre 150 e 200 cm3/min, obtendo-se filmes de diversas morfologias. Os filmes foram caracterizados quanto à morfologia da superfície pela Microscopia de Força atômica e quanto à sua natureza química pela espectroscopia Ramano

Full textAbstract:
L'objectif principal de notre étude est de saisir le contenu social des mutations que "l'œuvre industrialisatrice" peut entrainer sur la société et l'espace urbain marocains, et cela à travers l'analyse de la croissance industrielle et urbaine de Safi (Maroc sud). L'examen de la situation du logement fait apparaitre en premier lieu, un décalage de l'offre par rapport à la demande. Ce décalage n'est en fin de compte qu'une des conséquences du fonctionnement même du système urbain qui entretient de façon permanente les conditions de ce déséquilibre. Il s'agit d'abord du mouvement d'industrialisation entame à partir des années 60, dont le fait majeur réside dans la mise en place d'un ensemble industriel moderne (le complexe chimique) basé exclusivement sur une technique importée de l'occident. Safi cité portuaire et artisanale est désormais appelée à devenir un "pôle de développement industriel". En effet la croissance des besoins en logement du fait de l'accroissement urbain et des implantations industrielles, dépasse de loin les capacités de production de logements et les systèmes de traitement économique et institutionnel du problème. L'office chérifien des phosphates arrive à résoudre le problème pour une partie de son personnel (cadres et certains ouvrier spécialisés) la capacité d'intervention des organismes d'état et du groupe O. C. P. Apparait assez modeste par rapport à la demande de plus en plus grande. Les opérations entreprisent par L'E. R. A. C. à Safi restent limitées.

Full textAbstract:
When is it acceptable to make fun of religion, and when does it become disrespectful? On January 7, 2015, the headquarters of the French satirical news paper Charlie Hebdo was subjected to a terrorist attack that claimed the lives of 12 staff members, due to the publishing of caricatures picturing the prophet Muhammed. The reactions that followed the attack circled around two perspectives; the importance of freedom of expression and the obligation to show respect for certain institutions and traditions in society. How come the caricatures can elicit such completely different reactions? This is the question that this thesis uses as a starting point for the examination of the subject caricatures and satire. The thesis examines caricatures and satire from a rhetorical perspective. It distinguishes four rhetorical aspects of caricature, and discusses if these rhetorical aspects can be what makes the difference regarding how provocative a drawing is considered. The thesis then uses the four rhetorical aspects found, to analyze two caricatures from the French satiric magazine Charlie Hebdo.

Full textAbstract:
Uppsala University Hospital aims to automate its drug management and distribution system in order to increase the speed and accuracy of the prescription process and reduce prescription errors. In order to achieve those goals, the hospital plans to introduce Closed-Loop- Medication (CLM). CLM enforces digitalization and automation of the entire drug management process. Studies show that CLM can reduce prescription errors. The Closed Loop Medication Management System is an electronic drug management process that automates drug management and disease management and documents all relevant patient history information. Drug prescription verification is one of the prerequisites in order to implement CLM.The purpose of this thesis is to find solutions to support and improve the prescription verification routines at Uppsala University Hospital. The first part of the report consists of a literature review about CLM and its impact. The second and main part describes a solution that can facilitate the implementation of CLM at the hospital with focus on the prescription verification process. More specifically, I developed an interface prototype with the name VerifyPro. User-Centred Design (UCD) method was followed for the development of VerifyPro. UCD is an iterative design process in which designers focus on the users and their needs in each phase of the design process. Finally, user requirements for the new interface were gathered by performing interviews at the hospital. Analysis on the responses from the interviews illustrated some problems on the hospital’s information system (COSMIC). On top of that the user needs became clear. Healthcare professionals need a support decision system that can supplement and facilitate their decision process. Last but not the least, they desire a customisable interface where users view only what they need to view about a patient. VerifyPro was designed to work supplementary to COSMIC. Its goal is to improve the prescription verification process, improve the communication between the health professionals, and lastly to provide a better and customisable overview of patient data.

Emergency first responders are the great heroes of our day, having to routinely risk their lives for the safety of others. Developing robotic technologies to aid in such emergencies could greatly reduce the risk these individuals must take, even going so far as to eliminate the need to risk one life for another. In this role, humanoid robots are a strong candidate, being able to take advantage of both the human engineered environment in which it will likely operate, but also make use of human engineered tools and equipment as it deals with a disaster relief effort.
The work presented here aims to lessen the hurdles that stand in the way through the research and development of new humanoid robot technologies. To be successful in the role of an emergency first responder requires a fantastic array of skills. One of the most fundamental is the ability to just get to the scene. Unfortunately, it is at this level that humanoid robots currently struggle.
This research focuses on the complementary development of physical hardware, digital controllers, and trajectory planning necessary to achieve the research goals of improving the locomotion capabilities of a humanoid robot. To improve the physical performance capabilities of the robot, this research will first focus on the interaction between the hip and knee actuators. It is shown that much like the human body, a biped greatly benefits from the use of biarticular actuation. Improvements in efficiency as much as 30% are possible by simply interconnecting the hip roll and knee pitch joints.
Balancing and walking controllers are designed to take advantage of the new hardware capabilities and expand the terrain capabilities of bipedal walking robots to uneven and non-stationary ground. A hybrid position/force control based balancing controller stabilizes the robot's COM regardless of the terrain underfoot. In particular two feedback mechanisms are shown to greatly improve the stability of bipedal systems in response to unmodelled dynamics. The hybrid position/force approach is shown through experiments to greatly extend humanoid capabilities to many types of terrain.
With robust balancing ensured, walking trajectories are defined using an improved linear inverted pendulum model that incorporates the swing leg dynamics. The proposed method is shown to significantly reduce the control authority (by 50%) required for satisfactory trajectory following. Three parameters are identified which provide for quick manual or numerical solutions to be found to the trajectory problem.
The walking and balance controller were operated on four different terrains successfully, strewn plywood, gravel, and high pile synthetic grass. Furthermore, SAFFiR is believed to be the first bipedal robot to ever walk on sand. The hardware enabled force control architecture was very effective at modulating ground reaction torques no matter the ground conditions. This in combination with highly accurate state estimation provided a very stable balance controller on top of which successful walking was demonstrated.Ph. D.

My result address the problem that getting back up in the boat after one have fallen in can be very difficult. My research led me to focus on the very smallest boats, rowing boats and open motorboats under 6 meters in length. My solution to the problem is to provide an easily attached footstep that can be reached and pulled down from water level. The product can be adapted to different boats. For the smallest boats, manually activated flotation units can be integrated to prevent the boat from tipping.

Abstract: Common bean (Phaseolus vulgaris L.) of great socioeconomic importance for Brazil, being the second largest producer and main consumer worldwide. The objective of this work was to understand the available methodologies for the management and evaluation of water use in irrigated crops and to estimate current evapotranspiration (ETa) and to determine crop coefficients in areas cultivated with winter bean using techniques based on remote sensing SAFER - Simple Algorithm for Retrieving Evapotranspiration), comparing them with estimates of crop evapotranspiration (ETc) recommended by FAO Bulletin 56. The study was conducted under central pivot irrigation conditions with seven winter bean sowing seasons in the municipalities of Rubinéia and Pereira Barreto. Each sowing season received an irrigation management, performed by the irrigator and a suggested irrigation simulation, maintaining the same ETo and rainfall data. The images of the LandSat 8 satellite were used to execute the SAFER algorithm to obtain the relation between the current evapotranspiration and the reference evapotranspiration. The water productivity was analyzed according to the production obtained for each sowing season. For the autumn / winter bean sowing in Rubinéia, the irrigant has the option to use data from the Ilha Solteira and Marinópolis Stations, a fact that ETo are similar. Results obtained from the irrigations used by the irrigator overestimated the water storage in the soil, so it was necessary to carr... (Complete abstract click electronic access below)

Resumo: A partir da perspectiva da História das Idéias Lingüísticas, investigam-se as filiações ao filósofo Friedrich W. Nietzsche (1844-1900) nas Ciências da Linguagem. Perguntando-se sobre os pontos de contato entre as diversas teorias lingüísticas e o pensamento do filósofo, propõe-se a filiação da chamada hipótese Sapir-Whorf à filosofia de Nietzsche. Desse modo, procura-se compreender a constituição das teorias e dos métodos lingüísticos a partir do campo heterogêneo que caracteriza as Ciências da Linguagem. Apresenta-se com esse fim um panorama do problema da linguagem em Nietzsche e, em seguida, defendem-se os graus de consonância e dissonância entre os autores. Desse modo, argumenta-se que Nietzsche é uma condição de possibilidade para o pensamento de E. Sapir e B. Whorf. No jogo entre memória e esquecimento, é sempre lembrado o nome de W. von Humboldt enquanto "precursor" da hipótese. Percebe-se, entretanto, que no gesto epistemológico de "olhar para trás" em busca de bases, muitas vezes os autores, quando "voltam" desse gesto, o fazem já afetados por toda uma gama de outras idéias que modificaram a primeira, e é nesse sentido que se apresenta a filiação da hipótese a Nietzsche
Abstract: As from the point of view of History of Linguistic Ideas, the research investigates the filiations to the philosopher Friedrich Nietzsche (1844-1990) on the Language Sciences. By questioning the contact points between the various linguistic theories and the philosopher's thoughts, the filiation of the so-called Sapir-Whorf hypothesis to Nietzsche's philosophy is proposed. Thus, It seeks the understanding on the linguistic theories and methods constitution, as from the heterogeneous field that characterizes the Language Sciences. In order to do so, it presents an overview on the matter of language at Nietzsche and, thereafter, the levels of consonance and dissonance among the authors are endorsed. Hence, it is defended that Nietzsche represents a condition of possibility for E. Sapir and B. Whorf's reasoning. As in the play-off between memory and forgetfulness, the name of W. von Humboldt is always recalled as the "forerunner" of the hypothesis. It can be perceived, however, that on the epistemological act of "looking back" in search for ground, the authors often "return" from this gesture rather affected by a whole other range of ideas that have, thus, modified the previous ones, and it is in that sense that the hypothesis filiation to Nietzsche presents itself

Full textAbstract:
Since the 1950s, men and women, mainly Rastafari from the West Indies, have moved as repatriates to Shashamane, Ethiopia. This is a spiritually and ideologically oriented journey to the promised land of Ethiopia (Africa) and to the land granted by His Imperial Majesty Emperor Haile Selassie I. Although migration across regions of the global south is less common than migration from the global south to north, this move is even more distinct because it is not primarily motivated by economic concerns. This thesis - the first in-depth ethnographic study of the repatriate population - focuses on the conceptual and pragmatic ways in which repatriates and their Ethiopian-born children “rehome” this area of Shashamane that is now called Jamaica Safar (or village in the Amharic language). There is a simultaneous Rasta identification of themselves as Ethiopians and as His Majesty’s people, which is often contested in legal and civic spheres, with a West Indian social inscription of Shashamane. These dynamics have emerged from a Rastafari re-invention of personhood that was fostered in West Indian Creole society. These ideas converge in a central concern with the inalienability of the land grant that is shared by repatriates, their children and Rastafari outside Ethiopia as well. Accordingly, the repatriate population of Shashamane becomes the centre of international social and economic networks. The children born on this land thus demonstrate the success of their parents’ repatriation. They are the ones who will ensure the Rastafari presence there in perpetuity.

Denna undersöknings syfte är att redogöra för den finlandssvenska satirens skildring av språkstriden i Finland under mellankrigstiden. Huvudkällan för detta ändamål är skämttidningen Garm som innehar en unik position i den finska skämtpressens historia. Genom att analysera tidskriftens årgångar från perioderna 1927-1931 och 1934-1939 besvaras frågan: ”Hur representeras språkstriden i relation till finlandssvensken?”. Det läggs vikt på vilken typ av samtidsfrågor som uttryckligen är relaterade till aktuella händelser rörande språkstriden, hur äktfinskheten och finsk nationalism representeras och hur språkliga skillnader skildras. Undersökningens resultat visar att Garm anser att språkstriden, i och med förträngningen och begränsningen av det svenska språket, var ett hot för samhällets enighet. I både nationellt och internationellt hänseende skulle det finska samhället splittras och mer eller mindre gå under.
