This thesis presents the development of an interactive programming system for the IBM 7545 robot. Various methods of robot programming are discussed, and the reasons for the development of such an interactive programming system are provided. The development of this system was divided into five phases, namely, the development of the pseudo-compiler, development of the "system control" program, integration of ASSEMBLY routines, development of the "motion control" program, and the development of test programs. The approach used for each of these five stages are outlined, and a reference to the use of the system is given. A description of the development of each stage is then given, and the logic associated with all programs are described, and the purpose and operation of all subroutines are also presented. Some assumptions and limitations of the system are explained, and the operational aspects of the system are described. Additional work needed to improve this system is outlined, and the feasibility of using the concept of this system on other robot programming languages on the IBM 7545 robot are also discussed. / M.S.

Many milestones have been passed in computer science and currently we are on our way to pass yet another: artificial intelligence. One of the characteristics of AI is to be able to interpret so-called unstructured data, i.e., data that lacks structure. Unstructured data can be useful and with the new tools within AI is it possible to interpret it and use it to solve problems. This has the potential to be useful in practical applications such as processing and decision support. The work has been done at Apendo AB, which has the Swedish National Land Survey as a customer. The work is to investigate how AI-driven cognitive services through IBM Watson can be applied to the Swedish National Land Survey. The goal is to answer the following questions: Is it possible to apply cognitive services through Watson's services to give decision support to the Swedish National Land Survey already? In what ways can you use Watson's services to create a decision support? How effective can the solution for the Swedish National Land Survey be, i.e. how much time and costs can they save by using Watson's services on the chosen concept? As a practical part of the AI study, a perceptron was developed and evaluated. Through an agile approach, tests and studies about IBM Watson have taken place in parallel with interviews with employees at the Swedish National Land Survey. The tests were performed in the PaaS service IBM Bluemix with both Node-RED and an own built web application. Though the interviews, the Watson service Retrieve and Rank became interesting and examined more closely. With Retrieve and Rank you can get questions answered by ranking selected corpus pieces that are then trained for better answers. Uploading the corpus with related questions resulted in that 75% of the questions was answered correctly. Applications for the Swedish National Land Survey can then be a cognitive search function that helps administrators to search information in manuals and the law book. / Många milstolpar har passerats inom datavetenskapen och just nu håller vi på att passera en till: artificiell intelligens. En av de egenskaper som kännetecknar AI är att kunna tolka s.k. ostrukturerad data, alltså sådan data som saknar struktur. Ostrukturerad data vara användbar och med de nya verktygen inom AI är det möjligt att tolka för sedan använda det till att lösa problem. Detta har potential att vara användbart inom praktiska applikationer såsom handläggning och beslutsstöd. Arbetet har skett på företaget Apendo AB som har Lantmäteriet som kund. Arbetet går ut på att undersöka hur AI-drivna kognitiva tjänster genom IBM Watson kan tillämpas på Lantmäteriet. Målet är att besvara följande frågor: Är det möjligt att tillämpa kognitiva tjänster genom Watsons tjänster för att ge beslutsstöd åt Lantmäteriet redan i dagsläget? På vilka sätt kan man använda Watsons tjänster för att skapa ett beslutsstöd? Hur effektiv kan lösningen för Lantmäteriet bli, d.v.s. hur mycket tid och kostnader kan de tänkas spara genom att använda Watsons tjänster på valt koncept? Som praktisk del av studien om AI utvecklades och utvärderades en perceptron. Genom ett agilt förhållningssätt har tester och studier om IBM Watson skett parallellt med intervjuer med anställda på Lantmäteriet. Testerna utfördes i PaaS-tjänsten IBM Bluemix med både Node- RED och egenbyggd webbapplikation. Av intervjuerna blev Watson-tjänsten Retrieve and Rank intressant och undersöktes noggrannare. Med Retrieve and Rank kan man få frågor besvarade genom rankning av stycken av valt korpus som sedan tränas upp för bättre svar. Uppladdning av korpus med tillhörade frågor gav att 75 % av frågorna besvarades korrekt. Tillämpningarna Lantmäteriet kan då vara en kognitiv uppträningsbar sökfunktion som hjälper handläggare att söka information i handböcker och lagboken.

O objetivo do presente trabalho foi determinar, através de medidas de Ressonância Fluorescente Nuclear (RFN) para o núcelo deformado de 153Eu, a intensidade integrada de ressonâncias localizadas de dipolo associadas a modos de movimento como o modo tesoura Ml (ressonâncias anãs). Foi utilizado o feixe de elétrons do acelerador Dynamitron da Universidade de Stuttgart (Eo = 4,3 MeV) e detetores de Ge(HP) e Ge(Li) de alta resolução para a obtenção de informações detalhadas acerca das energias de excitação, larguras de decaimento, probabilidades de transição e razões de ramificação. Os resultados obtidos para o 153Eu são comparados com os obtidos recentemente para seus vizinhos ímpares (161,163Dy, 155,157Gd e 159Tb) e com as previsões do Modelo de Bósons e Férmions Interagentes (MBFI). Enquanto os isótopos ímpares de Dy apresentam uma certa concentração de intensidade de dipolo ao redor de 3MeV, os isótopos ímpares de Gd apresentam uma extrema fragmentação de intensidade de dipolo (25 transições para o 155Gd e 90 transições para o 157Gd), na faixa de energia de 2-4 MeV. O núcleo de 153Eu quando comparado aos isótopos ímpares de Dy, Gd e Tb, apresenta uma pequena fragmentação, com baixa intensidade de dipolo. Em geral, a intensidade de dipolo total em núcleos ímpares é menor (por um fator 2-3), quando comparada com seus vizinhos pares. Esta diferença de intensidade entre os isótopos ímpares de Eu, Dy, Gd e Tb é inexplicável até agora. / The aim of this work was to perform Nuclear Resonance Fluorescence (NRF) measurements for the 153Eu deformed nucleus associated to Ml scissors mode. Using the bremsstrahlung photon beam of the Stuttgart Dynamitron (endpoint energy 4.3 MeV) and high resolution Ge spectrometers, detailed information was obtained on excitation energies, decay widths, transition probabilities, and branching ratios. The results are compared to those observed recently for the neighboring odd nuclei 161,163Dy, 155,157Gd and 159Tb and with the Interacting Boson Fermion Model (IBFM). Whereas in the odd Dy isotopes the dipole strength is rather concentrated, both Gd isotopes show a strong fragmentation of the strength into about 25 (155Gd) and 90 transitions (157Gd) in the energy range 2-4 MeV. The nucleus 153Eu as compared to these odd Dy, Gd and Tb isotopes exhibits a small fragmentation with low strength. In general the observed total strength in the odd nuclei is reduced by a factor of 2-3 as compared to their neighboring even-even isotopes. The different fragmentation behavior of the dipole strengths in the odd Dy, Gd, Tb and Eu isotopes is unexplained up to now.

Dans une première partie, nous proposons un nouveau modèle de chemostat dans lequel la population bactérienne est représentée de manière individu-centrée, structurée en masse, et la dynamique du substrat est modélisée par une équation différentielle ordinaire. Nous obtenons un processus markovien que nous décrivons à l'aide de mesures aléatoires. Nous déterminons, sous une certaine renormalisation du processus, un résultat de convergence en loi de ce modèle individu-centré hybride vers la solution d'un système d'équations intégro-différentielles. Dans une seconde partie, nous nous intéressons à des modèles de dynamiques adaptatives du chemostat. Nous reprenons le modèle individu-centré étudié dans la première partie, auquel nous ajoutons un mécanisme de mutation. Sous des hypothèses de mutations rares et de grande population, les résultats asymptotiques obtenus dans la première partie nous permettent de réduire l'étude d'une population mutante à un modèle de croissance-fragmentation-soutirage en milieu constant. Nous étudions la probabilité d'extinction de cette population mutante. Nous décrivons également le modèle déterministe associé au modèle individu-centré hybride avec mutation et nous comparons les deux approches, stochastique et déterministe; notamment nous démontrons qu'elles mènent au même critère de possibilité d'invasion d'une population mutante dans une population résidente.Nous présentons des simulations numériques illustrant les résultats mathématiques obtenus. / In the first part, we propose a new chemostat model in which the bacterial population is mass structured and individual-based and the substrate dynamics are modelized by an ordinary differential equation. We obtain a Markovian process which we describe as random measures. We determine, under a certain normalization of the process, a result of convergence in distribution towards the solution of a system of integro-differential equations. In the second part, we are interested in adaptive dynamic models of the chemostat. We add a mutation mechanism to the individual-based model which was studied in the first part. Under rare mutations and large population size hypotheses, the asymptotical result of the first part allows us to reduce the study of the mutant population to a growth-fragmentation-washout model in a constant environment. We study the extinction probability of this mutant population. We also describe the deterministic model related to the hybrid individual-based model with mutations and we compare these two approaches (stochastic and deterministic). In particular we prove that the two approaches lead to the same invasion criteria of a mutant population in a resident population.We present numeric simulations in order to illustrate the mathematical results.
