StarLogo TNG (The Next Generation) is a graphical programming environment originally developed by the MIT Scheller Teacher Education Program as a means of improving computer literacy and programming skills in middle and high school students. The original goal of StarLogo TNG was to make computer programming more accessible to students by designing a programming framework, StarLogoBlocks, which could graphically represent the control flow and data structures of a program, and to introduce a "coolness" factor by permitting students to view their program's execution in a 3D game-like environment called SpaceLand. However, after the program was released, the team found that researchers and professionals were using StarLogo TNG for more complex agent-based simulations than it had been originally designed to support. This thesis outlines the design and implementation of a new suite of features, code-named SimLogo, which will improve the simulation capabilities of StarLogo TNG through the addition of true internal parallelism to the virtual machine.

StarLogo TNG is "The Next Generation" in block-based decentralized programming for modeling and simulation software. Its aim is to make computer programming more appealing for students in middle school and high school. Part of the draw of StarLogo TNG is its 3-D rendered world called Spaceland where "agents" live on a terrain made of a grid of "patches". This thesis evaluates and outlines the redesign of Spaceland and its associated terrain editor based on user-task analysis, and discusses the design of new data structures to support the desired features.

StarLogo: The Next Generation aims to introduce students to programming. The StarLogo application is frequently used in a classroom setting, but the effectiveness of StarLogo is limited as long as students cannot interact with each other using the application. This thesis describes the design and implementation of a networked development and runtime environment for StarLogo. Hopefully, students will become more interested in programming when they can collaborate to create and run StarLogo programs. In addition, teachers will have more options available when choosing classroom activities using StarLogo.

StarLogo TNG is a robust graphical programming environment for secondary students. Despite the educational advantages of graphical programming, TNG has sustained criticism from some who object to the exclusion of a textual language. Recognizing the benefits of text processing and the power of controlling software with a keyboard, I sought to incorporate text-processing techniques into TNG's graphical language. The key component of this work is an innovation dubbed "Typeblocking," by which users construct block code through the use of a keyboard.

Full textAbstract:
Grazie alla conoscenza dell'evoluzione stellare e alle isocrone di ultima generazione, l'et\'a degli ammassi aperti (AA) pu'\o essere misurata con accuratezza, in particolare se se ne conosce la composizione chimica.
La possibilit\'a di accurata datazione unita alla loro distribuzione spaziale,
rendono gli OC traccianti ideali del disco galattico: essi infatti si trovano sia
nella zona centrale che in quella esterna del disco, vicino al piano galattico.
Gaia, con la {\it data release 2}, oltre a fornire parallassi precisi, ha portato al rilevamento di molti nuovi ammassi, aprendo una nuova era per lo studio del disco galattico. In seguito a questo, varie campagne osservative, anche all'interno di grandi progetti che usano spettrografi multi-fibra di ultima generazione, si sono concentrate (o si concentreranno) sullo studio della composizione degli AA.
Tuttavia, i dati ottenuti con questi strumenti non consentono una completa caratterizzazione chimica delle stelle degli AA, limitandone l'utilizzo nel sondare l'evoluzione chemo-dinamica del disco.
Questo progetto si inserisce nel progetto {\it Stellar Population Astrophysics (SPA) with TNG}, il cui obbiettivo \'e mappare ed esplorare la chimica del disco della Via Lattea
Parte di questo lavoro prevede l'uso di AA e la derivazione della loro composizione chimica precisa e accurata.
In questo lavoro presentiamo l'analisi di un campione di AA situati entro circa 2 kpc dal Sole, con et\'a da circa 50 Myr a pochi Gyr.
Abbiamo utilizzato HARPS-N al Telescopio Nazionale Gaileo e raccolto spettri ad altissima risoluzione (R = 115\,000) di 40 stelle giganti rosse del {\it Red Clump} in 18 AA (di cui 16 mai o poco studiati, e due di riferimento).
Ne abbiamo misurato le loro velocità radiali e derivato i parametri stellari ($T_{\textrm{eff}}$, log g, v$_{micro}$, e [Fe/H]) utilizzando un approccio 1D - LTE basata sull'analisi delle larghezza equivalente delle righe.
Abbiamo inoltre misurato l'abbondanza degli elementi $\alpha$, O, Mg, Si, Ca, Ti e degli elementi a cattura protonica Na e Al, tutti determinati con il metodo della larghezza equivalente. Abbiamo anche misurato l'abbondanza di Li attraverso il metodo di sintesi.
Abbiamo discusso la relazione tra metallicit\'a e distanza galattocentrica, aggiungendo i dati della letteratura ai nostri risultati per ampliare il campione e tenendo conto anche dell'et\'a.
I risultati ottenuti per Litio, Sodio e Alluminio sono stati discussi nel contesto dell'evoluzione stellare. In particolare, per Na e Al abbiamo confrontato i nostri risultati con i modelli per studiare il loro comportamento in funzione della massa, suggerendo che l'aumento evolutivo di Na nell'atmosfera stellare di giganti potrebbe iniziare addirittura partire da 2\,M$_{\bigodot}$.
Abbiamo poi studiato i {\it trends} delle abbondanze radiali, verticali e per et\'a. trovando gradienti significativi (positivi) solo per [Mg/Fe] e [Ca/Fe].
Infine, i valori di Fe, O e Mg nel campione combinato sono stati confrontati con l'ultima generazione di modelli chemo-dinamici, trovando un buon accordo per i cluster di età intermedia e vecchi.
Per gli ammassi pi\'u giovani, troviamo un forte aumento della dispersione delle composizioni chimiche misurate, accompagnato da un {\it fit} assai pi\'u scadente con i modelli per Fe, O e Mg. Sono state esplorate diverse possibili spiegazioni, comprese le incertezze nella metallicit\'a derivata, confermando la difficolt\'a nella determinazione dei parametri per le stelle giovani (età $<$ 200 Myr), probabilmente a causa di una combinazione di fattori intrinseci (attività, rotazione veloce, campi magnetici, ecc.) che i modelli atmosferici non possono riprodurre facilmente e che influenzano i parametri e incertezza di misura chimica.Context: Thanks to modern understanding of stellar evolution, we can accurately measure the age of Open Clusters (OCs). Given their position, they are ideal tracers of the Galactic disc. Gaia data release 2, besides providing precise parallaxes, led to the detection of many new clusters, opening a new era for the study of the Galactic disc. However, detailed information on the chemical abundance for OCs is necessary to accurately date them and to efficiently use them to probe the evolution of the disc. Aim: Mapping and exploring the Milky Way structure is the main aim of the Stellar Population Astrophysics (SPA) project. Part of this work involves the use of OCs and the derivation of their precise and accurate chemical composition. We analyze here a sample of OCs located within about 2 kpc from the Sun, with ages from about 50 Myr to a few Gyr. Method: We used HARPS-N at the Telescopio Nazionale Gaileo and collected very high-resolution spectra (R = 115\,000) of 40 red giant/red clump stars in 18 OCs (16 never or scarcely studied plus two comparison clusters). We measured their radial velocities and derived the stellar parameters ($T_{\textrm{eff}}$, log g, v$_{micro}$, and [Fe/H]) based on equivalent width measurement combined with 1D - LTE atmospherical model. Moreover, the abundance of $\alpha$-elements O, Mg, Si, Ca, Ti, and the light elements Na and Al, all determined by the equivalent width method. We also measured Li abundance through the synthesis method. Result: We discussed the relationship between metallicity and Galactocentric distance, adding literature data to our results to enlarge the sample and taking also age into account. We discussed the behaviors of lithium, sodium and aluminum in the context of stellar evolution. For Na and Al, we compare our findings with models to investigate their behaviour as a function of mass, suggesting that Na mixing to the surface during the giant phase might start in masses as low as 2\,M$_{\bigodot}$. We study the radial, vertical, and age trends for the measured abundance ratios in a sample combining our results and recent literature for Open Clusters, finding significant (positive) gradients only for [Mg/Fe] and [Ca/Fe] in all cases. Finally, we compare Fe, O and Mg in the combined sample with chemo-dynamical models, finding a good agreement for intermediate-age and old clusters. There is a sharp increase in the abundance ratios measured among very young clusters (age $<$ 300 Myr ), accompanied by a poorer fit with the models for O and Mg. Several possible explanations are explored, including uncertainties in the derived metallicity. We confirm the difficulties in determining parameters for young stars (age $<$ 200 Myr), due to a combination of intrinsic factors (activity, fast rotation, magnetic fields, etc) which atmospheric models can not easily reproduce and which affect the parameters and chemical measurement uncertainty.

This thesis outlines a 10-unit biology curriculum implemented in StarLogo TNG. The curriculum moves through units on ecology, the DNA-protein relationship, and evolution. By combining the three topics, it aims to highlight the similarities among different scales and the relationships between them. In particular, through the curriculum, students can see how small-scale changes in molecular processes can create large-scale changes in entire populations. In addition, the curriculum encourages students to engage in problembased learning, by which they are trained to approach questions creatively and independently.

Full textAbstract:
Nous avons étudié les mécanismes enzymatiques impliqués dans la bioconversion de la trinitroglycérine (TNG) par un champigon filamenteux : Phanerochaete chrysosporium ainsi que sa métabolisation par des extraits de cellules hépatiques. Les résultats suivants ont été mis en évidence : - Le mycelium dégrade la TNG en 2-MNG avec un rendement de 90% et une régiosélectivité de 80%. Les spectres RPE effectués au cours de l'incubation de la TNG mettent en évidence la formation de complexes hémoprotéine-NO et protéine Fe-S-NO intracellulaires. - La dégradation de la TNG par P. Chrysosporium met en jeu différents systèmes enzymatiques composés de plusieurs activités solubles et membranaires. L'activité cytosolique est constituée d'une activité glutathion-transférase et d'une hémoprotéine de type cytochrome P-450. Une hémoprotéine semble intervenir au niveau des activités liées aux membranes et plus particulièrement de type cytochrome P-450 dans la fraction microsomiale. - Des microsomes de foie de rat induit au phénobarbital interagissent avec la TNG pour donner un spectre UV-visible de type I alors qu'en anaérobie et en présence de NADPH apparaît un spectre caractéristique d'une interaction cytochrome P-450-NO. Ces microsomes dégradent la TNG en ses dérivés di et mononitrés. Parmi les inducteurs de cytochromes P-450 étudiés, la dexaméthasone augement nettement la concentration des cytochromes P-450 efficaces dans la dégradation réductive de la TNG. Ce résultat, de même que les effets d'inhibiteurs spécifiques, permet d'impliquer la forme IIIA du cytochrome P-450We have studied the eniymatic mechanisms involved in the bioconversion of glyceryl trinitrate (GTN) by a filamentous fungus : Phanerochaete chrysosporium and in the GTN metabolization by hepatic cells extract. The following resuits have been pointed out - The fungus degrade GTN in 2-GMN with a rate of 90% and 80% of regioselectivity. EPR spectra made during GTN incubation show the formation of intracellular complexes identified like hemoprotein-NO and protein Fe-S-NO. - The GTN degradation by P. Chrysosporium involved enzymatic systems_ constituted by soluble and membrane activities. The cytosolic activity is constituted by a glutathion-transferase and by an hemoprotein like cytochrome P-450. Hemoproteins seems to be involve in membrane activities and in particular a cytochrome P-450 in microsomal fraction. - Hepatic rat microsomes, induced by phenobarbital, interact with GTN to form a type I spectrum. In presence of NADPH and in anaerobic condition, a spectrum appeared, caracteristic of an interaction cytochrome P-450-NO. These microsomes degrade GTN in di and mononitrated derivatives. Amongst the cytochrome P-450 inducer tested, dexamethasone increases stongly the concentration of cytochrome P-450 involved in the reductive degradation of GTN. This result and the effect of specific inhibitors allow us to involve the IIIA form of cytochrome P-450

Pour évaluer les performances des systèmes de communications sans fil, un simulateur matériel de canal MIMO (Multiple-Input Multiple-Output) est réalisé pour les nouveaux systèmes de communication. Il fournit la vitesse de traitement nécessaire et permet d’évaluer les performances en temps réel. Il permet de comparer les différents systèmes dans les mêmes conditions souhaitées. Les objectifs de ce travail concernent principalement les modèles de canal MIMO et l'architecture de bloc numérique du simulateur matériel.Le simulateur matériel conçu peut être configuré avec les nouveaux réseaux radio-mobiles (LTE) et les réseaux locaux sans fil (WLAN 802.11ac). Il utilise des modèles de canaux standardisés, comme le TGn IEEE 802.11n et le 3GPP-LTE, ou des résultats de mesures effectuées avec un sondeur de canalMIMO conçu et réalisé dans notre laboratoire. Récemment, le sondeur de canal a été utilisé au cours de campagnes de mesure pour des environnements à bord d’un navire et de l’extérieur-vers-l’intérieur (outdoor-to-indoor). Un algorithme est proposé pour que les réponses impulsionnelles mesurées soient compatibles avec la bande des signaux LTE. En outre, le modèle de Kronecker avec des évanouissements de Rayleigh est utilisé pour obtenir un canal variant dans le temps.Le simulateur doit être capable de reproduire différents types d'environnement. Dans ce contexte, de nombreux scénarios ont été proposés. Ils considèrent le mouvement à l'intérieur et à l'extérieur pour des environnements et des réseaux hétérogènes. Un algorithme est proposé et analysé pour basculer entre les environnements d’une manière continue. Ces réseaux offrent des services à travers un réseau cellulaire à l'aide du LTE et sont capables de maintenir le service lors du passage à un réseau local sans fil WLAN 802.11ac.Deux architectures pour le bloc numérique du simulateur matériel sont proposées. La première opère dans le domaine fréquentiel en utilisant des modules de transformée de Fourier rapide (FFT/IFFT). Dans ce contexte, une nouvelle architecture fréquentielle améliorée qui fonctionne avec des signaux d'entrée de longue durée est proposée. La seconde opère dans le domaine temporel en utilisant des filtres à Réponse Impulsionnelle Finie (FIR).Les architectures ont été implémentées sur des circuits programmables (FPGA : Field Programmable Gate Array) Virtex-IV de Xilinx. Leurs occupations sur FPGA, la précision des signaux de sortie et leur latence sont analysées et comparées. De plus, une solution basée sur un facteur d’échelle automatique (ASF: Auto-Scale Factor) est introduite pour augmenter la précision des signaux de sortieTo evaluate the performance of the emerging mobile and wireless communication systems, a Multiple-Input Multiple-Output (MIMO) channel hardware simulator is designed and implemented using the recent communication standards. It provides the processing speed required to the real-time performance evaluation and allows comparing various systems in the same test conditions. The objectives of this work mainly concern the MIMO channel models and the digital block architecture of the hardware simulator. The hardware simulator can be configured with Long Term Evolution (LTE) and Wireless Local Area Network (WLAN) 802.11ac signals. It uses standard channel models, as 3GPP LTE and TGn IEEE 802.11n. It also allows replaying measurement results obtained with the MIMO channel sounder designed and realized at our laboratory. In fact, data obtained during measurement campaigns onboard a ship and for outdoor-to-indoor environments were used. The measured impulse responses are pre-processed in order to make them compatible with LTE or 802.11ac signals. Moreover, timevarying channel models are obtained using Kronecker model with Rayleigh fading.The simulator must be able to reproduce different types of environment. In this context, many scenarios considering realistic people movements have been proposed. They involve movements in outdoor, indoor, outdoor-to-indoor or heterogeneous environments. An algorithm is proposed and described to switch between the environments in a continuous manner. Heterogeneous wireless communication systems are also considered. These systems provide service through a cellular network using LTE standard and are able to maintain the service when switching to a WLAN 802.11ac, for example.Two architectures for the digital block of the hardware simulator are proposed. The first operates in the frequency domain using Fast Fourier Transform (FFT/IFFT) modules. A new improved frequency architecture that works for streaming mode input signals is proposed. The second operates in time domain using Finite Impulse Response (FIR) filters.The architectures of the digital block of the hardware simulator are implemented on a Field Programmable Gate Array (FPGA) Virtex-IV from Xilinx. Their occupation on the FPGA, the accuracy of the output signals and their latency are analyzed and compared. Moreover, a new algorithm, based on an Auto-Scale Factor (ASF), is added for the time domain architecture. This algorithm improves the precision of the output signals

The purpose of this thesis is to evaluate the performance and cost effectiveness of a Peroxone Groundwater Treatment Plant (PGTP) designed and operated by Montgomery Watson, in support of the Defense Evaluation Support Agency's independent analysis for the United States Army Environmental Center (USAEC). Many Department of Defense installations have sites that contain groundwater contaminated with explosive materials. Primary methods for the removal of explosive materials involve the use of Granular Activated Carbon (GAC). This process, however, requires additional waste disposal and treatment of explosive laden GAC, thereby incurring additional costs. An alternate method for the treatment of contaminated groundwater involves the use of hydrogen peroxide (H2O2) in conjunction with ozone (03). This method is referred to as the Peroxone oxidation process. A demonstration of the PGTP was conducted from 19 August to 8 November, 1996, at Cornhusker Army Ammunition Plant (CAAP), Grand Island, Nebraska using a small scale version with a maximum flow rate of 25 gallons per minute. The explosive contaminants analyzed during the demonstration include 2,4,6-Trinitrotoluene (TNT), 1,3,5-Trinitrobenzene (TNB), 1,3,5-Triazine (RDX), and Total Nitrobodies. Peroxone cost effectiveness was evaluated using a 30 year life cycle cost comparison to GAC and Ultraviolet/Ozone processes

Humanity has always dreamed about a better world. These dreams has manifested themselves in the vision of Utopia - the good place, but also the non-existing place. Up until World War II man still wrote optimistic descriptions of this ideal world, and spread the idea through literature. In the aftermath of the atomic bomb and under the influence of the cold war, these publications seized to surface in literary surroundings. Despite this utopia did not die - it has only changed. Today you can find utopia, not primarily in books, but in Science Fiction. TV’s biggest Science Fiction-series, Star Trek, is perhaps the best example of this. The Master's thesis "Utopia Trek - a travel through Star Trek with the concept of utopia" takes you through the history of utopia and into its new habitat, Star Trek, where the essence of a utopia for the 21th century is found, discussed and reevaluated.

Efter hotet från atombomben och under påverkan av det kalla kriget, slutade dessa publikationer att dyka uppi litterära sammanhang. Trots detta dog inte drömmen utopia - det har bara förändrats. Idag kan man finna utopia, inte företrädesvis i böcker, utan i science fiction. Tv:s största science fiction-serie, Star Trek, är kanske det bästa exemplet på detta. Magisteruppsatsen "Utopia Trek - utopibegreppets resa genom Star Trek" tar dig genom utopias historia och in i dess nya hemvist, Star Trek, där essensen av ett utopia för 2000-talet upptäcks, diskuteras och omvärderas.

Full textAbstract:
This dissertation constitutes a detailed investigation of the history of the Lok Sin Tong Free School. It discusses how benevolent societies expanded their service scope in Hong Kong, as well as how the reforms in the education system and teaching curriculum of mainland China affected those in Hong Kong in the 1930s.
Lok Sin Tong, one of the most remarkable charitable organizations in pre-war Hong Kong, formally expanded into the education field in 1929 with the establishment of the Lok Sin Tong Free School. The School was located at 32 Dai Tit Street, and its aim was to provide free education to children from Kowloon City who had formerly been deprived of schooling. The School began accepting male applicants in 1930. The first principal was Tam Kit-Sang, and the second was Wong Bun-Po. The School offered primary education and a four-year curriculum focusing on Chinese education. By 1938, when a new campus was established, the School’s number of students exceeded 300. However, soon after the outbreak of the Pacific War and Japanese occupation of Hong Kong in December 1941, the School was forced to close its doors.
This dissertation comprises six chapters. The first defines the term “free school” and reviews the history of research on the Lok Sin Tong Free School. The second chapter outlines the historical development of Kowloon City and the Kowloon Walled City prior to 1941, and discusses how the local Kowloon City culture was key to the reestablishment of Lok Sin Tong’s services in the late 1920s following a suspension of services early in the century. The third chapter traces the origins and narrates the development of Lok Sin Tong from 1880 to 1941, with an emphasis on the improvement in its services under the leadership of Tam Kit-Sang and Chan Cho-Chak. The fourth chapter investigates the Lok Sin Tong Free School between 1929 and 1941, with special attention paid to its size, the quality of its teachers, its administration, curriculum and pedagogy, and student performance. An evaluation of the School’s overall effectiveness on the basis of these criteria follows. The fifth chapter presents a comparative study of the teaching and learning activities of the Lok Sin Tong Free School and those of the (1) Long Jin Free School and (2) Tung Sin Tong Free School. This comparison reveals the transformation of and changes in Chinese education in Hong Kong. The last chapter concludes the dissertation with a discussion of the interactions among free schools, benevolent societies, and the local community and culture in Hong Kong.published_or_final_version

This thesis examines the roost selection preferences of bat species present in the Yugar tunnel. The aim of this study is to increase knowledge of bats roosting in artificial structures in anthropogenically modified landscape. The Yugar Tunnel in South-East Queensland is thought to be inhabited by three species of insectivorous bats. Little is known about the bats roosting there, and this project aimed to study three key aspects of their roosting and foraging behaviour. In doing so, this thesis examines the bat species and population size, along with the emergence and return patterns, and the roosting selection preferences.

Full textAbstract:
ZBLAN glass shows great potential in the application of long-haul telecommunication cables. However, during processing in the fibre-drawing temperature region, the material tends to crystallize, resulting in large transmission losses. In this study, ZBLAN glass was processed with different cooling rates to discern how the rate of cooling affects the process of crystallization. The results of this study revealed that by rapidly cooling ZBLAN test samples, it was possible to completely impede all crystallization phenomena and yield a fully amorphous glass suitable for use as an optical waveguide.

Full textAbstract:
This thesis studies Tang sancai, a multi-coloured lead-glaze ceramic decorated ware which emerged in the Tang dynasty (AD 618 - AD 907), attaining mass production in the middle of the Tang era and declining towards its end. It examines the functions of sancai in its different aspects, namely as burial objects, as containers for ritual offerings and as architectural material. I argue that Tang sancai ware as burial objects were employed exclusively by the Tang imperial and elite families. The approach to my argument is made, in a first stage, through the observation of the physical locations of tombs that contained Tang sancai wares to demonstrate that these tombs belonged to the Tang imperial and elite family members. In a further step, I bring up two Tang decrees which laid down regulations for burials, to indicate that there was a strict hierarchical system for the allocation and utilization of burial land. These two Tang texts enable us to establish that the tombs located around the area of the imperial tombs belonged to the Tang officials and elite, and therefore not to ordinary people. In addition, the study I undertake of the structure of the tombs, with layout and organization mirroring palatial environments, reinforces my argument to that end. Lastly, I look at the cost of production of Tang sancai showing that it was higher than that of unglazed ceramics and that, consequently, sancai wares were, from an economical point of view, inaccessible to the common people. This thesis also reflects on the agency of Tang sancai, considering its aesthetic qualities and its suitability in the functions for which it served, as a force in engaging the viewers. The lasting debate on whether Tang sancai utensil-shaped wares were used for everyday eating and drinking is dealt with in this thesis by carefully examining the locations of the shards that were excavated at the sites of imperial palaces. My research enables to point out that this data is not sufficient to ascertain that this type of Tang sancai was used as daily wares. On the contrary, on the grounds that these locations were the places where ritual performances took place, I argue that sancai utensil wares were used as presentation containers for ritual performances. In the absence of records in Tang texts which could have informed about the relationship between Tang sancai and religious practice, I borrow an evidence from Japan, in the form of the hand-brush writing on a couple of Nara sancai dishes, which were copies of Tang sancai made in Japan during the time of Tang, mentioning that these vessels were specifically for use for ritual ceremonies. Furthermore, on the basis of analyses made on lead-glazed ware, some scholars assert that such ware is poisonous and could not have been used to contain food or drink, as much as no evidence exists to show that ancient Chinese had used lead-glazed wares for that purpose. This leads to the clarification that Tang sancai utensil-shaped wares were not produced for everyday use, their purpose having actually been to serve as vessels for offerings in rituals. I further observe that this connection between sancai and ritual-themed objects, initiated by the Tang, has in fact pervaded through the succeeding dynasties affirming its role in religious ceremonials. Finally, this thesis also looks at Tang sancai as an architectural material to show that it was skillfully used in decorating buildings, not only as tiles and tile-ends, but also as large-sized roof ornaments. The research reveals, in the process, the possible dates when sancai architectural material started to be used popularly during the Tang era.

As obras de construção de tubulações e dutovias para o transporte de matéria, principalmente na indústria do petróleo e gás, apresentam na atualidade constante crescimento, causando relevantes impactos econômicos e produtivos para o desenvolvimento do país. Neste tipo de obra, as etapas de soldagem são um fator determinante para melhores produtividades, em relevância, o passe de raiz. Atualmente, a soldagem manual com Eletrodo Revestido e TIG ainda são predominantes, porém este cenário vem mudando à medida que equipamentos e procedimentos automatizados são desenvolvidos. Dentre as tecnologias presentes, a soldagem TIG orbital mecanizada tem se apresentado como uma boa solução para os passes de raiz e preenchimento, principalmente na soldagem de ligas especiais. Contudo, o Brasil ainda não detém a tecnologia de fabricação de equipamentos desta natureza e tampouco existem metodologias e banco de informações referentes a procedimentos de soldagem para estas aplicações. A fim de contribuir para o desenvolvimento científico-tecnológico, o presente trabalho abrange as duas carências citadas. Primeiramente, buscou-se a otimização do sistema orbital (cabeçote e fonte de soldagem) a partir de melhorias no sistema AVC (Arc Voltage Control), programa da fonte de soldagem, dispositivos mecânicos do cabeçote, etc., capacitando o equipamento protótipo às operações orbitais. A segunda parte do trabalho concerne aos ensaios de bancada. Estes foram realizados sobre juntas chanfradas de tubulações de aço baixa liga com 406,4 mm (16") de diâmetro e parede de 12,7 mm (1/2"). O estudo abrange desde as etapas de fabricação dos corpos de prova à levantamento de procedimento em 360°. Foram analisadas questões quanto à geometria do cordão nas diferentes posições de soldagem, técnica de alimentação de arame, descontinuidades, geometria do bisel, entre outras. Para isto, alguns equipamentos foram utilizados tais como câmera filmadora, sistema de aquisição de dados e software para edição de imagens e modelagem 3D. Os resultados obtidos mostraram competência do equipamento, bem como o levantamento e compreensão da problemática e de fatores determinantes e influentes na soldagem TIG orbital.
Abstract: The construction of pipelines for matter transportation, mainly in the Oil & Gas industry, has shown constant growth, causing significant economics and productive impacts on the country's development. In this kind of building, the determining factors for best yields are welding stages, in relevance, the root pass. Currently, manual welding with Stick Welding or TIG are still prevalent, but this scene is changing as automated equipment and procedures are developed. Among these technologies, mechanized orbital TIG welding has emerged as a good solution for the root pass and filling passes, especially for the welding of special alloys. However, Brazil still does not have the manufacturing technology of these equipments, nor are methodologies and knowhow for welding procedures for these applications. In order to contribute to the scientific and technological development, this paper covers the two aforementioned shortcomings. First, the optimization of orbital system (head and welding source) from improvements in AVC (Arc Voltage Control), power source program, mechanical devices, weldhead, etc., enabling the prototype equipment for orbital operations. The second part concerns the welding tests. These were carried out on beveled joints of low alloy steel pipes with 406.4 mm (16 ") in diameter and 12.7 mm wall (1/2"). The study covers from the manufacturing stages of the specimens to the specification of a 360° root pass procedure. Questions regarding the bead geometry in the different welding positions, wire feeding technique, discontinuities, bevel geometry, among other factors were analyzed. For this purpose, some devices have been used such as camcorder, data acquisition system and software for image editing and 3D modeling. The results showed the reliability of the equipment, technical and operational knowhow of orbital TIG welding.

No âmbito dos processos de soldagem, a capacidade inerente do ser humano de perceber erros e atuar para corrigi-los torna segura a adoção de processos manuais. Por outro lado, a produtividade destes processos já não é mais compatível com as exigências do mundo atual. O desenvolvimento de equipamentos com implementações que aumentem o grau de automatização e reduzam a influência do operador têm sido um requisito para a busca contínua da melhoria da produtividade. Situação diferente ocorre no Brasil, cuja indústria se caracteriza pelos elevados custos de mão de obra, decorrentes da baixa produtividade, que dificilmente alcança o nível obtido no contexto internacional. No campo da soldagem, melhorias em termos de produtividade vêm sendo conseguidas por países com grande desenvolvimento industrial que souberam elevar o nível de produção por trabalhador utilizando dois princípios básicos: o investimento em equipamentos e o estudo de novas técnicas aliadas a procedimentos de soldagem. Em vista disto, o presente trabalho tem como objetivo geral o desenvolvimento de técnicas para a realização da soldagem TIG orbital de tubos que resultem no aumento da produtividade, visando aplicações do setor de petróleo e gás. Fazem parte do trabalho não somente a definição de procedimentos de soldagem, mas também a realização de melhorias no equipamento, utilizando uma versão do processo TIG com alimentação dinâmica de arame. Neste caso, a alimentação do arame é feita automaticamente, mas de forma análoga às ações de um soldador, com a introdução de um movimento de avanço e recuo em frequência próxima de 1Hz. Para isto, foi desenvolvido um novo modelo de cabeçote alimentador capaz de sincronizar a movimentação do arame com o estágio de pulsação da corrente, um sistema de medição da velocidade de alimentação, e um dispositivo direcionador. Na etapa de caracterização do processo, ensaios comparativos entre a alimentação contínua e dinâmica de arame foram realizados, com avaliação da variação do gradiente térmico em função de diferentes frequências de oscilação. Em seguida, deu-se início aos ensaios de soldagem orbital em seções de tubos de aço ASTM-A139 Grau D, com diâmetro de 16? (406,4 mm) e espessura de 15 mm. Os procedimentos propostos enfatizaram o aumento da produtividade do passe de raiz, com a adoção de umchanfro tipo ?U?, com 3 mm de ?nariz?, maior que o utilizado usualmente, de 2 mm. Como resultado, obteve-se penetração total ao longo de 180°, com velocidade média de soldagem de 27,8 cm/min, valor este que é bastante superior aos 10 cm/min do processo TIG com alimentação contínua, e similar à verificada no MIG/MAG, cujo valor médio é de 29,5 cm/min. A dimensão média da solda (altura da área fundida) foi de 4,5 mm, também maior se comparada às dos demais processos (2,9 mm do MIG/MAG e 2,8 mm do TIG convencional). A relação de equilíbrio entre velocidade de alimentação e potência não é um requisito para a estabilidade, o que permitiu adicionar pouco material com o intuito de favorecer a penetração. Os resultados obtidos demonstraram o potencial da versão desenvolvida sob o ponto de vista de produtividade. No entanto, foi constatado o fato de que algumas juntas não cumpriram todos os critérios prescritos pelas normas internacionais de forma repetitiva. Na posição sobre cabeça (8h, 7h e 6h) identificou-se a presença de algumas descontinuidades como concavidade e mordedura. Em função disto, tendo em vista o grande potencial sob o aspecto de produtividade na aplicação de soldagem orbital, entende-se ser oportuno dar sequência ao aprimoramento do processo em outros trabalhos de pesquisa, de forma a superar as limitações observadas até o presente momento.
Abstract : Regarding welding processes, human ability to detect errors and correct them enables manual process execution. On the other hand, productivity is no longer compatible to new world requirements. The development of welding equipments with higher automation level and less operator dependence have been crucial for continuous improvement of productivity. A different scenario is found in Brazil. Its industry has high labor costs due to low productivity, which rarely reaches international levels. In the welding field, productivity have been accomplished in countries with high industrial development. They have raised output per worker through two basic principles: equipments and new techniques combined with welding procedures. Because of this, the main objective of this work is to develop techniques for orbital TIG welding focused on productivity increase in the oil and gas sector. The work covers procedure specifications as well as equipment upgrade, using a TIG process with dynamic wire feeding. In this case, there is an automatic feeding that mimics welder operation, with a forward and backward movement near 1 Hz. We developed a new model of wire feeder, able to synchronize wire movement with current pulse. In the characterization phase, comparative tests were executed between continuous and dynamic wire feeding, with thermal gradient evaluation as a function of oscillation frequency. Then, orbital welding tests were performed in pipe sections of ASTM-A139 Grade D, with 16? diameter (406,4 mm) and 15 mm thickness. Productivity increase of root pass was emphasized through ?U? geometry bevel and ?nose? thickness of 3 mm, greater the usual one of 2 mm. The results show that penetration was reached over 180°, with average welding speed of 27,8 cm/min, better than 10 cm/min from TIG process with continuous feeding, and similar to MIG/MAG, which average value is 29,5 cm/min. Average weld dimension (fusion zone height) was 4,5 mm, also greater than other processes (2,9 mm from MIG/MAG and 2,8 mm from continuous feeding TIG). The balance between feed speed and power is not required for process stability, and allowed less material deposition to favor penetration. The above outcomes showed considerable potential from productivity perspective. However, we noted that some joints did not satisfy all requirements prescribed in international standards repetitively. Inoverhead position (8h, 7h e 6h), there were some discontinuities such as concavity and undercut. Therefore, taking into account the great orbital welding potential to increase productivity, is convenient to start process upgrade through new research projects to overcome present limitations.

Följande arbete är en undersökning om specifikt vad vardagsrummet är för rum, vad innehåller det och vad har det för funktion. Hur kan detta speglas i föremål och möbler? Hur kan kunskap om hur vi människor relaterar oss till föremål utvecklas i skolan? Vardagsrummet är ett rum där de ”finare” möblerna finns. Där vi umgås när vi har besök. Undersökningsmetoden bygger på en gestaltande undersökningsmetod. Genom litteraturstudier av etnologisk och sociologisk litteratur skrivna av Åke Daun, Eva Londos, Pierre Bourdieu mfl., fotodokumentation och egna erfarenheter har jag analyserat likheter och skillnader då det gäller två generationers olika vardagsrum. Resultatet av denna undersökning är att vardagsrummet och dess föremål förstärker den man är eller vill vara. Två generationers vardagsrum kan se väldigt olika ut. Men de speglar var och en på sitt sätt två olika individer. Jag ser mitt arbete som en undersökning som man kan överföra till elevers vardag och verklighet, ett tillfälla att reflektera över sina egna rum och saker. Eleverna fick i uppgift att välja ut ett föremål att ta med till skolan för att berätta om sin relation till föremålet genom att teckna av det och berätta minnen kring det. Något som jag kom fram till är att eleverna identifierar sig med föremålen. Eleverna använder föremålen för att förstärka sin självbild.

Le facteur tnf alpha (tumor necrosis factor-alpha) est une cytokine pluripotente qui stimule les cellules a l'aide de deux recepteurs membranaires distincts, tnf-r55 et tnf-r75. Cette these a eu pour objectif de definir le role de chaque recepteur du tnf, en particulier sur les cellules endotheliales et les fibroblastes. L'activation des cellules endotheliales et des fibroblastes par le tnf alpha, est essentiellement orchestree par le recepteur tnf-r55. Ce recepteur controle l'induction des proprietes adhesives de ces cellules a l'egard des leucocytes en stimulant l'expression de molecules d'adhesion a leur surface; il stimule leur activite secretoire, influence leur vitesse de proliferation et declenche l'activation du facteur nucleaire nf-kappab. A l'inverse, bien que demontree, la fonction du tnf-r75 s'integre mal au sein d'un processus biologique. Cependant, plusieurs resultats suggerent une collaboration entre les recepteurs tnf-r55 et tnf-r75, qu'elle soit de type ligand passing a la surface des cellules ou intracellulaire au niveau de la transduction du signal. L'activation du recepteur tnf-r75 peut egalement etre conditionnelle, dependant d'une costimulation avec l'interferon-gamma. De maniere generale, la fonction du recepteur tnf-r75 est tres specifique du type cellulaire considere. En conclusion, c'est le recepteur tnf-r55 qui apparait comme le plus important au niveau du processus inflammatoire et probablement aussi lors de maladies inflammatoires

Full textAbstract:
Tumor necrosis factor α (TNFα) is a pleiotropic cytokine that is predominantly produced by activated macrophages. The effects of TNFα are as diverse as the cells with which it interacts, e.g., stimulating fibroblast growth, exerting cytotoxic/cytostatic; activity against various human and murine cell lines, promoting inflammation through upregulation of endothelial adhesion molecules and IL-8 production. Yet TNFα is best known, and in fact was originally described, for its role in the bacterial-induced hemorrhagic necrosis of tumors and exacerbation of septic shock in which aberrant TNFα production leads to vascular collapse, cachexia, multiple organ failure, and ultimately death in as many as 100,000 people each year in the United States alone. LPS, a component of the outer cell wall of gram-negative bacteria, is the principal inducer of macrophage TNFα production. TNFα production can be enhanced by IFNγ which also induces upregulation of TNFα receptors allowing for the establishment of a TNFα autocrine loop. It has been hypothesized that autocrine TNFα stimulation plays a critical role in the induction of macrophage effector function, e.g., nitric oxide production. This dissertation represents efforts to evaluate the respective roles of the TNFα receptors in the induction of macrophage effector function, in addition to examining the mechanism by which autocrine TNFα exerts its effects on macrophages. Exploiting the species specificity of the murine TNFα receptor type 2 (TNF-R2), splenic macrophages were stimulated with human TNFα (which binds to TNF-R1 but not TNF-R2), in the presence of IFNγ. Human TNFα was effective in the induction of nitric oxide production, albeit at concentrations 12.5-fold greater than those required by murine TNFα to achieve the same result. Addition of anti-TNF-R1 completely inhibited the murine TNFα mediated induction of macrophage effector function. However, treatment with anti-TNF-R2 resulted in partial inhibition of macrophage activation. Taken together this data suggests that the primary TNFα mediated signals involved in macrophage activation are transduced through TNF-R1, although TNF-R2 appears to contribute to the intensity of the macrophage response. To evaluate the role of autocrine TNFα signaling in the induction of macrophage effector function, immortalized macrophages from normal C57Bl/6J mice (B6/J2) and C57Bl/6J mice containing gene targeted disruptions of the TNF-R1 and TNF-R2 genes (TRN) were stimulated under CD14-dependent and CD14-independent conditions. Although the B6/J2 and TRN clones mounted similar NO responses to LPS in the presence of serum, the TRN macrophages generated a weak nitric oxide response as compared to B6/J2 when stimulated with LPS under serum-free conditions. The involvement of TNFα autocrine stimulation in the CD14-independent activation was corroborated by the ability of soluble TNF-R1 to inhibit the response of B6/J2 macrophages to LPS in serum-free medium. CD14-independent LPS stimulation of TRN and B6/J2 resulted in equivalent levels of IL-1β, TNFα, and NOS gene expression, as determined by RT-PCR, and in release of equivalent amounts of biologically active TNFα. However, western blot analysis revealed that NOS protein production by TRN was as much as 50% less than that produced by B6/J2. These results indicate that autocrine TNFα stimulation contributes to the signaling pathways initiated by ligation of CD14-independent LPS receptors and may be involved in NOS post-transcriptional regulation.

O TNF atua diretamente sobre a pineal inibindo a via biossintética da melatonina. De forma semelhante o LPS, potente ativador da resposta imune inata, tem efeito inibitório sobre a produção de melatonina e seu precursor. A supressão da síntese noturna de melatonina é admitida de forma a permitir a montagem da resposta inflamatória, tanto durante o dia como à noite. Dados do grupo tem demonstrado que o NFKB é um fator constitutivamente expresso na glândula pineal e que o ritmo diário de translocação pode ser determinante para o início da síntese de melatonina. A inibição de sua ativação potencia a síntese de melatonina enquanto que fatores que classicamente promovem a sua ativação inibem esta produção. Nesta dissertação, verificamos as moléculas envolvidas no reconhecimento e na de sinalização desta citocina na pineal. Demonstramos que a pineal está apta a responder ao TNF, células gliais da pineal e as células secretoras, os pinealócitos, expressam constitutivamente o receptor TNF-R1. O TNF promove a translocação nuclear dos dímeros p50/p50 e p50/RelA do NFKB em glândulas pineais em cultura. Confirmamos a ativação desta via em pinealócitos pela análise da proteína inibitória IKB. Vimos que a ativação desse fator é essencial para expressão da iNOS e a produção de NO induzida por TNF em pinealócitos isolados. Além disso, mostramos que o TNF promove a redução da expressão do receptor TNF-R1 na membrana de pinealócitos. Em resumo, mostramos neste trabalho que a pineal está instrumentalizada a responder ao TNF, e que os pinealócitos são alvos diretos para o seu reconhecimento. Confirmamos a relevância do fator NFKB na resposta da pineal em situações de injúria, ampliando o conceito de que a pineal está apta a detectar moléculas do processo inflamatório.TNF acts directly on the pineal gland by inhibiting the biosynthesis of melatonin. Similarly, LPS, a potent activator of the innate immune response has an inhibitory effect on the production of melatonin and its precursor. The suppression of nocturnal melatonin synthesis is admitted to allow the full mounting of the inflammatory response both during the day and night. Data from our laboratory have shown that the NFKB is constitutively expressed in the pineal gland and that the daily rate of translocation can be determinant for the onset of melatonin synthesis. Inhibition of their activation potentiates melatonin synthesis whereas factors that promote its activation classically inhibit this production. In this dissertation we find the molecules involved in recognition and signaling of this cytokine in the pineal. We demonstrated that the pineal is responsive to TNF, the pineal glial cells and secretory cells, the pinealocytes, constitutively express the TNF-R1. TNF promotes nuclear translocation of p50/RelA and p50/p50 NFKB dimers in the pineal glands in culture. We confirmed the activation of this pathway in pinealocytes by analyzing the inhibitory protein IKB. We have seen that the activation of this factor is essential for iNOS expression and NO production induced by TNF in isolated pinealocytes. Furthermore we show that TNF promotes the reduction of the expression of TNF-R1 receptor on the membrane of pinealocytes. In summary, we show here that the pineal is instrumented to respond to TNF and that the pinealocytes are direct targets for its recognition. We confirm the relevance of NFKB in the pineal response in situations of injury extending the concept that the pineal is able to detect molecules in the inflammatory process and respond accordingly.

Fem år har gått sedan hela världens strålkastare riktades mot länder i Mellanöstern och Nordafrika. Storögda och förväntansfulla var världspubliken när de såg hur tiotusentals människor samlades runt flera gator och torg och krävde att få sina röster hörda och att de styrande diktatorerna skulle avgå. Det skanderades då, år 2011, om demokrati och frigörelse från decennielånga förtryck. Men i dagens Egypten vittnar människor om att det under de här fem åren regredierat till ett lika illa, om inte värre, samhälle än innan. Oppositionella röster motverkas och tystas genom att sprida skräck hos dem som en gång vågat tala. En oförutsägbar statsapparat fängslar, griper och styr. Tunisien lyckades som det enda land att reformera statsskicket och gå från diktatur till ett demokratiskt styre. Men däremot är vissa viktiga institutioner, som polisväsendet, kvar i det gamla och påverkar de som redan är utsatta då landet befinner sig i ett politisk och ekonomisk limbo. I flera andra länder i regionen, brinner det än i dag fullbordade inbördeskrig. Vilka var det som så hängivet stod där på torgen och dessutom inspirerade fler till att ansluta sig? Och hur gick det sen för dem och deras länder?

This thesis project aims to develop an active Radio Frequency Identification tag (RFID) which uses an interesting method for positioning and ID detection. In this project, rather than classical ways of positioning methods such as triangulation or radio maps, infrared light and a camera with an infrared filter was used for the positioning. Tag identification detection is done by applying image analysis on camera images. When a specific part is wanted from the warehouse, this part is addressed through the active RFID system and the tag attached to that part starts to blink with the tag ID. A camera with an infrared filter above the goods in the ceiling finds the blinking infrared led, detects the tag’s position by image analysis, and confirms the ID with the requested ID number. A led transmitting visual light is used to ensure the tag also can be seen by the forklift driver in the warehouse environment when he is in close range of the part. First of all, related work and scientific papers were examined mostly from the IEEE database, which was instrumental in constructing this thesis project. Under the circumstances of low power consumption and the demands from the tag, additional possible components for an RFID tag such as an infrared led, a visual led, transistors for the LED amplifier stage and an LDO (Low-dropout) voltage regulator are chosen. Necessary technical calculations such as gain, power consumption are calculated. The RFID tag is built with these components, and transferred into the software environment .First the schematic is drawn and footprints created for the each component and the case styles are decided for transferring the circuit into the layout environment. For the radio circuit part which is used for the communication between the server and the tag, transmission lines of PCB demands are examined and the necessary calculations are made for impedance matching to prevent any disorder. After preparation of the PCB, gerber files are sent for the manufacturing process and the hardware part is completed. The components are mounted and the LED’s blinking time interval is set depending on the camera’s applicable frame speed, relevant tests for the ID detection and positioning (see fig.1). With optimisation of the time interval for recognition of the ID, an algorithm for the positioning of the RFID tag is developed and the related ID detection algorithm is developed for the real time applications by using a camera. As a result of this thesis project, instead of using complex systems for the positioning, such as triangulation or creating a radio map with multiple readers etc. a basic solution is produced as an alternative. The efficiency of the system, the distance that allows the positioning and how applicable the system is are examined.

Full textAbstract:
This report describes how we made a dynamic website combined with statical
web pages and a web shop for the Swedish company Tyger & Ting.
The employer Tyger & Ting wish to run a working web shop on their site but
they want to keep their old system of updating pages with their old application
from Intellyweb1, which creates statical HTML pages.
The goal of this exam paper has been to learn to create a functional web shop
with user friendly layout and appealing design and also to take orders and
fulfill wishes from a real employer.
The report is describing how Intellyweb’s application and its statical web pages
has been implemented on a dynamic web page. The report does also describe
how this site has been build and how the problems with the coding have been
solved. The coding has been made with HTML, PHP and MySQL. CSS has
also been used. The report will describe how management and storage of data
in databases has been handled.
Apart from the demands the employer has given us, a complete revamp of
Tyger & Ting’s design has been made and the result of the exam paper is now a
complete and working web site with additional web shop that supports static
web pages. The website contains 20 dynamic and static pages coded in about
1900 rows of PHP and HTML. A database with five tables of varying size has
been made to contain pictures and information about products, users and
orders.
As soon as all the products has been put into the database the web shop will be
found here: http://www.tygeroting.com

Full textAbstract:
Developing and maintaining software is a difficult task, and finding effective methods of understanding software is more necessary now than ever with the last few decades seeing a dramatic climb in the scale of software. Appropriate visualisations may enable greater understanding of the datasets we deal with in software engineering. As an aid for sense-making, visualisation is widely used in daily life (through graphics such as weather maps and road signs), as well as in other research domains, and is thought to be exceedingly beneficial. Unfortunately, there has not been widespread use of the multitude of techniques which have proposed for the software engineering domain.
Tag clouds are a simple, text-based visualisation commonly found on the internet. Typically, implementations of tag clouds have not included rich interactive features which are necessary for data exploration. In this thesis, I introduce design considerations and a task set for enabling interaction in a tag cloud visualisation system. These considerations are based on an analysis of challenges in visualising software engineering data, and the perceptive influences of visual properties available in tag clouds.
The design and implementation of interactive system Taggle based on these considerations is also presented, along with its broad-based evaluation. Evaluation approaches were informed by a systematic mapping study of previous tag cloud evaluation, providing an overview of existing research in the domain. The design of Taggle was improved following a heuristic evaluation by domain experts. Subsequent evaluations were divided into two parts - experiments focused on the tag cloud visualisation technique itself, and a task-based approach focused on the whole interactive system. As evidenced in the series of evaluative studies, the enhanced tag cloud features incorporated into Taggle enabled faster visual search response time, and the system could be used with minimal training to discover relevant information about an unknown software engineering dataset.
