Entretanto, tais simula??es exigem alto custo computacional e a sua completa execu??o pode se tornar uma tarefa impratic?vel devido ao vasto n?mero de informa??es estruturais consideradas para representar a expl?cita flexibilidade de receptores. Al?m disso, o problema ? ainda mais desafiante quando deseja-se utilizar modelos de receptores totalmente flex?veis (Fully-Flexible Receptor - FFR) para realizar a triagem virtual em bibliotecas de ligantes. Este estudo apresenta um m?todo inovador para otimizar a triagem virtual baseada em docagem molecular de modelos FFR por meio da redu??o do n?mero de experimentos de docagem e, da invoca??o escalar de workflows de docagem para m?quinas virtuais de plataformas em nuvem. Para esse prop?sito, o workflow cient?fico basedo em nuvem, chamado e-FReDock, foi desenvolvido para acelerar as simula??es da docagem molecular em larga escala. e-FReDock ? baseado em um m?todo seletivo sem param?tros para executar experimentos de docagem ensemble com m?ltiplos ligantes. Como dados de entrada do e-FReDock, aplicou-se seis m?todos de agrupamento para particionar conforma??es com diferentes caracter?sticas estruturais no s?tio de liga??o da cavidade do substrato do receptor, visando identificar grupos de conforma??es favor?veis a interagir com espec?ficos ligantes durante os experimentos de docagem. Os resultados mostram o elevado n?vel de qualidade obtido pelos modelos de receptores totalmente flex?veis reduzidos (Reduced Fully-Flexible Receptor - RFFR) ao final dos experimentos em dois conjuntos de an?lises. O primeiro mostra que e-FReDock ? capaz de preservar a qualidade do modelo FFR entre 84,00% e 94,00%, enquanto a sua dimensionalidade reduz em uma m?dia de 49,68%. O segundo relata que os modelos RFFR resultantes s?o capazes de melhorar os resultados de docagem molecular em 97,00% dos ligantes testados quando comparados com a vers?o r?gida do modelo FFR. / The use of conformations obtained from molecular dynamics trajectories in the molecular docking experiments is the most accurate approach to simulate the behavior of receptors and ligands in molecular environments. However, such simulations are computationally expensive and their execution may become an infeasible task due to the large number of structural information, typically considered to represent the explicit flexibility of receptors. In addition, the computational demand increases when Fully-Flexible Receptor (FFR) models are routinely applied for screening of large compounds libraries. This study presents a novel method to optimize docking-based virtual screening of FFR models by reducing the size of FFR models at docking runtime, and scaling docking workflow invocations out onto virtual machines from cloud platforms. For this purpose, we developed e-FReDock, a cloud-based scientific workflow that assists in faster high-throughput docking simulations of flexible receptors and ligands. e-FReDock is based on a free-parameter selective method to perform ensemble docking experiments with multiple ligands from a clustered FFR model. The e-FReDock input data was generated by applying six clustering methods for partitioning conformations with different features in their substrate-binding cavities, aiming at identifying groups of snapshots with favorable interactions for specific ligands at docking runtime. Experimental results show the high quality Reduced Fully-Flexible Receptor (RFFR) models achieved by e-FReDock in two distinct sets of analyses. The first analysis shows that e-FReDock is able to preserve the quality of the FFR model between 84.00% and 94.00%, while its dimensionality reduces on average 49.68%. The second analysis reports that resulting RFFR models are able to reach better docking results than those obtained from the rigid version of the FFR model in 97.00% of the ligands tested.

O presente estudo descreve as alterações metalúrgicas e topográficas do cilindro de blocos de motor de combustão interna fabricados em ferro fundido cinzento, após a realização de testes de durabilidade em dinamômetro. O motor testado tem tecnologia Flex-Fuel, e pode ser operado com qualquer proporção de mistura gasolina comum/etanol. Um motor foi testado com combustível etanol e o outro com gasolina comum, buscando-se assim representar duas condições extremas de trabalho em termos de combustível. A pesquisa constituiu-se da revisão bibliográfica e da parte prática que envolveu: a realização de testes de durabilidade de motor em dinamômetro; a caracterização metalúrgica e topográfica do cilindro após teste com ambos os combustíveis, utilizando técnicas de microscopia eletrônica de varredura, metalografia por microscopia óptica, perfilometria e quantificação de parâmetros de rugosidade, entre outros; a análise crítica, discussão dos resultados e apresentação da conclusão. / The present study approaches the metallurgical and topographical alterations on the cylinder of an internal combustion engine block made of gray cast iron, after durability dynamometer tests. The tested engine has flexible fuel technology (Flex-Fuel), and is capable to work with both gasoline/ethanol fuels, in any mixture proportion. One engine has been tested with ethanol and another one tested with gasoline, and so representing two extreme conditions on which the engine may work in terms of fuel. The research has been developed basically through the conceptual approach by the bibliographic review and the experimental steps that involved: general engine durability test at dynamometer bench; metallurgical and topographic characterization analysis at laboratory, after the test with both fuels, applying Scanning Electronic Microscopy SEM, optical microscopy metallography, profilometer and roughness parameters quantification, and so forth; critical analysis on the results, discussion and final conclusion.

Field studies were conducted during 2006 and 2007 to evaluate control of saw greenbriar and southern dewberry by various pasture herbicides and to assess forage tolerance of Tifton 85 bermudagrass to these herbicides. Herbicides evaluated in each study included triclopyr, picloram, 2,4-D, fluroxypyr, dicamba, aminopyralid, metsulfuron methyl and various combinations of the above. Visual ratings were taken on each herbicide efficacy experiment. Visual evaluations of phytotoxicity, measurements of dry matter yield, and forage quality were quantified for each of the bermudagrass tolerance trials. Saw greenbriar was best controlled at approximately one year after treatment by triclopyr at 10.9% ae v/v with diesel as the carrier (88-98%), although the lower rate of triclopyr + diesel at 0.87% ae v/v + 5% v/v and triclopyr alone at 0.87% ae v/v provided 49 to 86% control. Triclopyr + fluroxypyr at 0.25% ai v/v + 0.086% ai v/v gave best control of southern dewberry in both years when applied as an individual plant treatment (IPT) six weeks after shredding. In general, shredding 45 days prior to herbicide application gave an advantage to southern dewberry control versus not shredding. In 2006, triclopyr + fluroxypyr (IPT) was the only treatment to decrease Tifton 85 dry matter yield at the first harvest, with no effect observed at the second harvest. In 2007, both broadcast treatments containing triclopyr + fluroxypyr and the IPT treatment of triclopyr decreased dry matter yield at the first harvest, with triclopyr (IPT) being the only treatment to lower dry matter yield at the second harvest. Field studies were also conducted in 2006 and 2007 to assess sharppod morningglory control in Roundup Ready Flex® and LibertyLink® cotton systems. Herbicides evaluated included glyphosate, glufosinate, prometryn, fluometuron, and diuron. Visual ratings of percent weed control and sharppod morningglory plant counts were taken to assess control. Prometryn at 1.8 kg ai ha⁻¹ and fluometuron at 1.8 kg ai ha⁻¹ provided significant preemergence control (33-81%) of seedling sharppod morningglory. All rates of glyphosate (1.06 and 1.54 kg ai ha⁻¹) and glufosinate (0.45 and 0.6 kg ai ha⁻¹) controlled sharppod morningglory from 55 to 100% at both application timings. The addition of diuron at 1.12 kg ai ha⁻¹ to glyphosate and glufosinate at the late season application enhanced sharppod morningglory control by 3 to 16%. Additionally, in both years, no reduction in cotton yield was observed in the morningglory infested treatment when compared to the weed free treatment.

This research focuses on developing sensors for properties of aerodynamic interest (i.e., flow and pressure) based on low-cost polymeric materials and simple fabrication processes. Such sensors can be fabricated in large arrays, covering the surface of airfoils typically used in unmanned vehicles, allowing for the detection of flow separation. This in turn potentially enables, through the use of closed-loop control, an expansion of the flight envelope of these vehicles. A key advance is compensation for the typically inferior performance of these low cost materials through both careful design as well as new readout methods that reduce drift, namely a readout methodology based on aeroelastic flutter. An all-polymer micromachined piezoresistive flow sensor is fabricated, based on a flexible polyimide substrate and an elastomeric piezoresistive composite material. The flow sensor comprises a cantilever that is extended into the embedding flow; flow-induced stress on the cantilever is sensed through the piezoresistive composite material. Increasing the sensitivity of the sensor is achieved by either utilizing a long single-cantilever beam or using a dual-cantilever beam supporting a flap extending into the flow. In the latter case, the sensor demonstrates increased sensitivity with a reduced cantilever length. The increase in sensitivity helps to reduce sensor drift, which in turn is further reduced by a new measurement method, the vibration amplitude measurement method. In this drift reduction measurement method, the flow-induced vibration amplitude of the sensor structure (i.e., the amplitude of the aeroelastic flutter induced by the flow), instead of the absolute value of cantilever deflection, is measured in order to find the flow rate. Measurement of this relative resistance change instead of the absolute resistance in the piezoresistor rejects common-mode drift and greatly reduces overall drift. Experimental results verify the expected drift reduction. Sensor drift is also reduced when the elastomeric piezoresistive material is replaced by a Pt thin film piezoresistor. Development of pressure sensors based on polymers proceeds by encapsulating a reference cavity within a multilayer polymer structure and forming capacitor plates on the polymeric membranes encapsulating the cavity. Measuring the capacitance change induced by changes in the embedding pressure (which cause changes in the positions of the bounding polymeric membranes) enables calculation of the pressure. The use of polymeric membranes requires understanding the leakage rate of gas into the reference cavity, which is a source of pressure drift. Developing a polymer-based pressure sensor that solves the problem of sensor drift as a result of gas permeation entails the fabrication of a silicon pressure reference cavity embedded in the polymer substrate, which results in a more hermetic and lower drift sensor while preserving the flexibility of the embedding polymer. Both wired and wireless versions of pressure and flow sensors of these types were developed and characterized. Further, the sensors were characterized on airfoils and their performance in a wind tunnel was determined.

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 / 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.

[EN] Modern architecture in Valencia and some of its most important figures, have not been given to know in depth in the specialized literature. This Thesis aims to be a first approach to the work of one of these architects, Mauro Lleó Serret (1914- 2001) who left a great heritage but due to proximity, due to ignorance, or for not having recognized its value has been often undervalued. While it's true that his work begins in the era of autarchy, with formal expressions inspired by solutions of the past, he will soon be interested in architecture that is being done outside of Spain, of the great Masters as Mies, and will begin to incorporate details of it in their work. Thus, seven of his projects mark the passage to modernity in terms of compositional, technical and materials solutions. These will be two orders for the "Federación Sindical de Agricultores Arroceros de España": the project for the pavilion at the 1st International Fair of the field for the Rice National Cooperative in the Casa de Campo of Madrid (1953) and the project of rice factory in Sueca (1954), three industrial projects: project for a bottling plant of "Coca Cola" (1958) and the building for the metal fabrications factory FLEX (1961) , both in Quart de Poblet and the project for the S.E.A.T. branch in Valencia (1965), and finally two educational projects: the project of school in Valencia for the religious Institute of Purity (1962-1964) and the project of a building for Social Institute of Women (1966). Drawings, photographs of buildings in its current state, interviews with their users or the personal archive of the architect, among others, have been light, in addition to the possibility of a work of comprehensive analysis of certain works, to an approach to his career in the field of building from 1940 until 1976. This work doesn't forget neither the important contribution made by Mauro Lleó Serret in the field of urban planning and rehabilitation, but focuses on its role as an architect of buildings that did arouse the concern of the modern in Valencia. / [ES] La arquitectura moderna en Valencia y algunas de sus figuras más relevantes, no han sido dadas a conocer en profundidad en la bibliografía especializada. Esta Tesis pretende ser un primer acercamiento a la obra de uno de estos arquitectos, Mauro Lleó Serret (1914-2001) que dejó un gran patrimonio construido pero que, por cercanía, por desconocimiento, o por no haber reconocido su valor ha quedado en muchas ocasiones infravalorado. Si bien es verdad que su obra se inicia en la época de la autarquía, con manifestaciones formales inspiradas en soluciones del pasado, pronto pasará a interesarse por la arquitectura que se está haciendo fuera de España, la de los grandes maestros como Mies, y empezará a incorporar detalles de la misma en su trabajo. Así pues, siete de sus proyectos marcarán el paso hacia la modernidad en cuanto a soluciones compositivas, técnicas y materiales. Estos serán dos encargos para la Federación Sindical de Agricultores Arroceros de España: el proyecto de pabellón en la I Feria Internacional del campo para la Cooperativa Nacional del arroz en la Casa de Campo de Madrid (1953) y el Proyecto de factoría arrocera en Sueca (1954), tres proyectos industriales: el Proyecto de planta de embotellar "Coca-Cola" (1958) y el de edificio para fábrica de transformados metálicos FLEX (1961), ambos en Quart de Poblet y el Proyecto de filial de S.E.A.T. en Valencia (1965), y por último dos proyectos docentes: el proyecto de Colegio de Enseñanza en Valencia para el Instituto Religioso de la Pureza (1962-1964) y el Proyecto de edificio para Instituto Social de la Mujer (1966). Planos, fotografías de los edificios en su estado actual, entrevistas con sus usuarios o el archivo personal del arquitecto, entre otros, han dado luz, además de a la posibilidad de un trabajo de análisis exhaustivo de determinadas obras, a una aproximación a su trayectoria profesional en el campo de la edificación desde 1940 hasta 1976. Este trabajo no olvida tampoco la importante contribución de Mauro Lleó Serret en el campo del urbanismo y la rehabilitación, pero se centra en su papel como arquitecto de edificios que hicieron despertar la inquietud de lo moderno en Valencia. / [CAT] L' arquitectura moderna a València i algunes de les seues figures més rellevants, no s'han donat a conéixer amb profunditat a la bibliografia especialitzada.

Plànols, fotografies dels edificis al seu estat actual, entrevistes amb els seus usuaris o l'arxiu personal de l'arquitecte, entre d'altres, han donat llum, a més de a la possibilitat d'un treball d'anàlisis exhaustiu de determinades obres, a una aproximació de la seua trajectòria professional al camp de l'edificació des de 1940 fins a 1976. Aquest treball no oblida tampoc la important contribució de Mauro Lleó Serret al camp de l'urbanisme i la rehabilitació, però es centra amb el seu paper com arquitecte d'edificis que feren despertar la inquietud del modern a València. / Martinez Gregori, C.

Utveckling av teknik skapar ständigt nya möjligheter men innebär också stora förändringar för företag och organisationer. Mobiltelefoner, surfplattor, bärbara datorer, mobilkommunikation och molnteknik gör det möjligt idag att inte längre vara bunden av tid, plats eller en enhet för att kunna arbeta. Förändringen innebär att en ny typ av flexibla och yteffektiva kontor med inga fasta arbetsplatser blir allt vanligare. Problemet med de så kallade flexkontoren är att veta var eller när en kollega befinner sig på kontoret är inte lika självklart, framförallt om det är stort kontor med flera våningsplan. Målsättningen med detta arbete är att ta fram och implementera en inomhuspositioneringstjänst eller en så kallad Location-Based Service, till företaget Connecta AB. Tjänsten ska göra det möjligt för användare att med hjälp av sin mobiltelefon dela med sig av sin nuvarande arbetsplats i en kontorsmiljö. Resultatet av arbetet är en Location Based Service som gör det möjligt för en användare att med hjälp av en Androidtelefon med stöd för kortdistanskommunikationstekniken Near Field Communcication att dela med sig av sin nuvarande arbetsplats. Den molnbaserade serverlösningen Windows Azure används för att lagra registrerade arbetsplatser. / Development of technology constantly creates new opportunities but it can also mean major chang-es for companies and organizations. Today phones, tablets, laptops, mobile communications and cloud technology make it possible to be no longer bound by the time, location or device in order to work. The change means that a new office type that is more flexible and space efficient due to no fixed workplaces, is becoming more common. A problem with this type of offices that are known as flex-offices is that it is not obvious where or when a colleague is in the office, especially if it is large office with multiple floors. The aim of this work is to develop and implement a Location-Based Service for the company Connecta AB. The service will enable users to use their mobile phone to share their current workplace location in an office environment. The result of this work is a Location-Based Service that enables a user to use an Android phone with support for Near Field Communcication to share their current workplace position. The cloud-based server solution, Windows Azure is used to store indexed workplace positions.

This thesis is in the field of information design with a focus on spatial design. The study has been conducted to investigate how theories and methods in information design can be applied to digitally communicate activity zone functions in an activity-based flex office. Previous research indicates that one of the biggest challenges with the transition from celloffice to activity-based flex office is that the new way of working is not used as planned. A zoning that is obvious to everyone is recommended. The thesis includes a study of how employees relate to the workplace and how they interact with the digital tool Campuskartan, which has been applied to facilitate the everyday work. The methodological work includes a physical and digital site analysis that describes and evaluates visual elements and functions. It also includes an analysis of the factors that indicate strengths and challenges in terms of the interaction between the physical and the digital space. Employees at Mälardalen University have functioned as a focus group to capture needs from a user perspective and a qualitative interview with an expert have contributed good insights to the study. Subsequently, a participatory observation has been implemented to understand the university's communication work and overall goals with the transition to a new way of working. The study also has a scientific theoretical basis that includes previous research in activitybased flex office and how the digitalization has affected how we work. The study highlights theories in, among other things, visual communication and cognition as well as interaction design. With support from the methodological work, previous research and theories, a visual concept has been created in order to digitally communicate the functions of the activity zones and how employees can relate to them. / Detta är ett examensarbete inom informationsdesign med inriktning rumslig gestaltning. Studien har genomförts för att undersöka hur teorier och metoder inom informationsdesign kan tillämpas för att digitalt kommunicera aktivitetszoners funktioner på ett aktivitetsbaserat flexkontor. Tidigare forskning tyder på att en av största utmaningarna med övergången från cellkontor till aktivitetsbaserat flexkontor är att det nya arbetssättet inte nyttjas som planerat. En zonindelning som är tydlig för alla är även att rekommendera. Studien inkluderar en undersökning av hur medarbetare förhåller sig till arbetsplatsen samt hur de interagerar med det digitala verktyget Campuskartan som har tillämpats för att underlätta arbetsvardagen. Det metodiska arbetet inkluderar en fysisk och digital platsanalys som beskriver och värderar visuella element och funktioner. Det inkluderar även en analys av vilka faktorer som tyder på styrkor och utmaningar vad gäller samspelet mellan det fysiska och det digitala rummet. Medarbetare på Mälardalens högskola har fungerat som en fokusgrupp för att fånga upp behov ur ett användarperspektiv och en kvalitativ intervju med sakkunnig har genomförts i syfte att bidra med goda insikter till studien. Därefter har en deltagande observation genomförts för att förstå högskolans kommunikationsarbete och övergripande mål med övergången till ett nytt sätt att arbeta på. Studien har även en vetenskaplig teoretisk grund som inkluderar tidigare forskning inom aktivitetsbaserat flexkontor och hur digitaliseringen har påverkat hur vi arbetar. Studien lyfter teorier inom bland annat visuell kommunikation och kognition samt interaktionsdesign. Med stöd i det metodiska arbetet, tidigare forskning och teorier har ett visuellt koncept skapats i syfte att digitalt kommunicera aktivitetszonernas funktioner samt hur medarbetare kan förhålla sig till dem.
