O objetivo do presente trabalho foi promover uma análise comparativa do licenciamento e da certificação ambiental, para daí extrair uma fundamentação técnica e jurídica que possibilite verificar a interface entre eles. Utilizou-se uma abordagem teórico-metodológica da pesquisa social aplicada e jurídica, através de uma vertente jurídico-dogmática, bem como uma pesquisa dos fundamentos técnicos e sociais, para avaliação dos processos de certificação ambiental. Objetivou-se comprovar a existência de uma nítida interface entre licenciamento e certificação ambiental, embora não se possa admitir a suplantação da atividade estatal ou sequer a modificação das estruturas básicas da certificação. Recomenda-se um diálogo maior entre o Poder Público e as organizações privadas na busca de um desenvolvimento econômico que concretamente visa a sustentabilidade.

This thesis presents a design for an asynchronous interface to Robotiq adaptive gripper s-model. Designed interface is a communication layer that works on top of modbus layer. The design contains function definitions, finite state machine and exceptions. The design was not fully implemented but enough was so that it can be used. The implementation was done with c++ in linux environment. Additionally to the implementation a simple demo program was made to show the interface is used. Also grippers closing speed and force were measured. There is also a brief introduction into robotics and robot grasping.

Samples from 9 llamas (28 through 36 weeks of gestation) were collected and fixed in 4% buffered paraformaldehyde (light microscopy) and in 2.5% buffered glutaraldehyde (transmission and scanning electron microscopy). The material was processed in paraplast and slides (5mm) were stained with HE, PAS, Masson-Trichrome, acid phosphatase and Perl's. The uteroferrin was immunolocalized. The results show that llama placenta is chorioallantoic, diffuse, folded and epitheliochorial, and the fetus is covered with an epidermal membrane. The trophoblast cells have variable morphology: cubic, rounded and triangular cells, with cytoplasm containing PAS-positive granules. Binucleated cells with large cytoplasm and rounded nuclei, as well as giant trophoblastic cells with multiple nuclei were also observed. Numerous blood vessels were observed beneath the cells of the uterine epithelium and around the chorionic subdivided branches. Glandular activity was shown by PAS, Perl's, and acid phosphatase positive reactions in the cytoplasm and glandular lumen, and by immunolocalization of the uteroferrin in the glandular epithelium. The uterine glands open in spaces formed by the areoles, which are filled by PAS-positive material. The llama fetus was covered by the epidermal membrane, composed of stratified epithelium, with up to seven layers of mono-, bi- or trinucleated cells. The high level of maternal and fetal vascularization surfaces indicates an intense exchange of substances across both surfaces. The metabolic activity shown in the uterine glands suggests an adaptation of the gestation to the high altitudes of the natural habitat of this species.

Commercially available haptic interfaces are usable for many purposes. However, as generic devices they are not the most suitable for the control of heavy duty mobile working machines like mining machines, container handling equipment and excavators. Alternative mechanical constructions for a haptic controller are presented and analysed. A virtual reality environment (VRE) was built to test the proposed haptic controller mechanisms. Verification of an electric motor emulating a hydraulic pump in the electro-hydraulic system of a mobile working machine is carried out. A real-time simulator using multi-body-dynamics based software with hardware-in-loop (HIL) setup was used for the tests. Recommendations for further development of a haptic controller and emulator electric motor are given.
Model-View-Controller architectural pattern and its evolution in graphical user interface frameworks
Resumo:
Model-View-Controller (MVC) is an architectural pattern used in software development for graphical user interfaces. It was one of the first proposed solutions in the late 1970s to the Smart UI anti-pattern, which refers to the act of writing all domain logic into a user interface. The original MVC pattern has since evolved in multiple directions, with various names and may confuse many. The goal of this thesis is to present the origin of the MVC pattern and how it has changed over time. Software architecture in general and the MVC’s evolution within web applications are not the primary focus. Fundamen- tal designs are abstracted, and then used to examine the more recent versions. Prob- lems with the subject and its terminology are also presented.

The main objective of this work is to analyze the importance of the gas-solid interface transfer of the kinetic energy of the turbulent motion on the accuracy of prediction of the fluid dynamic of Circulating Fluidized Bed (CFB) reactors. CFB reactors are used in a variety of industrial applications related to combustion, incineration and catalytic cracking. In this work a two-dimensional fluid dynamic model for gas-particle flow has been used to compute the porosity, the pressure, and the velocity fields of both phases in 2-D axisymmetrical cylindrical co-ordinates. The fluid dynamic model is based on the two fluid model approach in which both phases are considered to be continuous and fully interpenetrating. CFB processes are essentially turbulent. The model of effective stress on each phase is that of a Newtonian fluid, where the effective gas viscosity was calculated from the standard k-epsilon turbulence model and the transport coefficients of the particulate phase were calculated from the kinetic theory of granular flow (KTGF). This work shows that the turbulence transfer between the phases is very important for a better representation of the fluid dynamics of CFB reactors, especially for systems with internal recirculation and high gradients of particle concentration. Two systems with different characteristics were analyzed. The results were compared with experimental data available in the literature. The results were obtained by using a computer code developed by the authors. The finite volume method with collocated grid, the hybrid interpolation scheme, the false time step strategy and SIMPLEC (Semi-Implicit Method for Pressure Linked Equations - Consistent) algorithm were used to obtain the numerical solution.

L‘interculturel est un concept souvent partagé mais rarement défini dans la recherche alors que ses compréhensions, interprétations et applications sont variées, ce qui mène à des malentendus et des positionnements épistémologiques et méthodologiques ambigus. En parallèle, de nombreuses critiques et propositions de réorientations de la notion voient le jour. Nous entendons faire le point sur la notion et son intégration potentielle dans l‘enseignement de la communication interculturelle (ECI). Notre étude se base sur l‘analyse de six groupes focalisés d‘enseignants (-chercheurs) impliqués dans l‘enseignement de l‘interculturel du niveau supérieur en Finlande, pays du nord de l‘Europe. Nous avons recours aux paradigmes postmodernes et aux sciences du langage (analyse du discours inspirée d‘auteurs français, et plus particulièrement de l‘école française de la deuxième génération (les théories de l‘énonciation (Kerbrat-Orecchioni, 2002 ; Marnette, 2005) et une approche du dialogisme inspirée par Bakhtine (1977))). Ces méthodes permettent de mettre en avant la complexité identitaire en posant l‘hétérogénéité du discours comme principe, c‘est-à-dire qu‘elles considèrent que tout discours inclut la « voix » de l‘autre. Repérer la présence de ces voix dans les discours des enseignants/chercheurs nous a permis de démontrer comment celles-ci participaient à la construction de leur identité pendant l‘interaction. Nous avons pu observer comment les relations entre ces interactions verbales donnaient lieu à des instabilités (contradictions, omissions), dont l‘étude nous a aidée à déduire leur(s) façon(s) de concevoir l‘interculturel. Les discours analysés révèlent a) que la définition de l‘interculturel est partagée sans être perçue de la même manière et b) que les différentes représentations du concept peuvent varier dans le discours d‘un même enseignant, mettant en évidences des contradictions qui posent problème s‘il s‘agit de communiquer un savoir-être aux apprenants. Nous nous sommes efforcée de trouver la place d‘un interculturel renouvelé parmi ces discours et de dissocier l‘image de l‘éducation interculturelle qui est promue en Finlande de ce qui est proposé en réalité : les changements actuels semblent avoir un minimum d‘impact sur la façon dont les enseignants traitent l‘interculturel. Nous nous demandons alors comment l‘Etat finlandais peut promouvoir un enseignement interculturel cohérent sans proposer aux enseignants/chercheurs une formation qui leur permettrait de reconnaitre les diverses diversités impliquées par l‘interculturel. Mots clés : Communication interculturelle, diversité, culture, enseignement supérieur finlandais.

Designing user interfaces for novel software systems can be challenging since the usability preferences of the users are not well known. This thesis presents a usability study conducted for the development of a user interface for game developers to enter game specific information. By conducting usability testing, the usability preferences of game developers were explored and the design was shaped according to their needs. An assessment of the overall usability of the final design is provided together with the main findings that include the usability preferences and design recommendations. The results showed that the most valuable usability preferences are quickness, error tolerance and the ability to constantly inspect the entered information.

Technological innovations, the development of the internet, and globalization have increased the number and complexity of web applications. As a result, keeping web user interfaces understandable and usable (in terms of ease-of-use, effectiveness, and satisfaction) is a challenge. As part of this, designing userintuitive interface signs (i.e., the small elements of web user interface, e.g., navigational link, command buttons, icons, small images, thumbnails, etc.) is an issue for designers. Interface signs are key elements of web user interfaces because ‘interface signs’ act as a communication artefact to convey web content and system functionality, and because users interact with systems by means of interface signs. In the light of the above, applying semiotic (i.e., the study of signs) concepts on web interface signs will contribute to discover new and important perspectives on web user interface design and evaluation. The thesis mainly focuses on web interface signs and uses the theory of semiotic as a background theory. The underlying aim of this thesis is to provide valuable insights to design and evaluate web user interfaces from a semiotic perspective in order to improve overall web usability. The fundamental research question is formulated as What do practitioners and researchers need to be aware of from a semiotic perspective when designing or evaluating web user interfaces to improve web usability? From a methodological perspective, the thesis follows a design science research (DSR) approach. A systematic literature review and six empirical studies are carried out in this thesis. The empirical studies are carried out with a total of 74 participants in Finland. The steps of a design science research process are followed while the studies were designed and conducted; that includes (a) problem identification and motivation, (b) definition of objectives of a solution, (c) design and development, (d) demonstration, (e) evaluation, and (f) communication. The data is collected using observations in a usability testing lab, by analytical (expert) inspection, with questionnaires, and in structured and semi-structured interviews. User behaviour analysis, qualitative analysis and statistics are used to analyze the study data. The results are summarized as follows and have lead to the following contributions. Firstly, the results present the current status of semiotic research in UI design and evaluation and highlight the importance of considering semiotic concepts in UI design and evaluation. Secondly, the thesis explores interface sign ontologies (i.e., sets of concepts and skills that a user should know to interpret the meaning of interface signs) by providing a set of ontologies used to interpret the meaning of interface signs, and by providing a set of features related to ontology mapping in interpreting the meaning of interface signs. Thirdly, the thesis explores the value of integrating semiotic concepts in usability testing. Fourthly, the thesis proposes a semiotic framework (Semiotic Interface sign Design and Evaluation – SIDE) for interface sign design and evaluation in order to make them intuitive for end users and to improve web usability. The SIDE framework includes a set of determinants and attributes of user-intuitive interface signs, and a set of semiotic heuristics to design and evaluate interface signs. Finally, the thesis assesses (a) the quality of the SIDE framework in terms of performance metrics (e.g., thoroughness, validity, effectiveness, reliability, etc.) and (b) the contributions of the SIDE framework from the evaluators’ perspective.
