Full textAbstract:
Le concept de carrière, autrefois considéré comme étant un chemin linéaire au sein d'une même entreprise dont les perspectives d'évolution étaient tenues pour acquis, semble aujourd'hui évoluer vers de nouveaux concepts de carrière. La rhétorique organisationnelle depuis la fin des années 1980 a progressivement évolué a d'un concept d'emploi long terme et permanent vers une nécessité claire de prise de responsabilité individuelle en vue d'assurer sa propre progression et son propre développement de carrière (Bolton & Gold, 1994; Baruch, 2006). En outre, les différences générationnelles et les avancées technologiques ont considérablement modifié l'environnement et le marché du travail, facilitant ainsi les échanges au-delà des frontières géographiques et introduisant la nécessité de gérer les différences culturelles (Crepeau et al., 2006). Nous analysons deux concepts de carrière afin de comprendre la vision contemporaine de carrière : en premier lieu, nous avons utilisé la théorie d'ancres de carrière développée par Schein (1978) qui a donné lieu à une compréhension plus large des différences individuelles ainsi que de la culture organisationnelle selon une perspective interdisciplinaire. Schein a défendu le point de vue que l'individu développe un « concept de soi » associé à sa carrière, qui devient une ancre stabilisant et influençant ses décisions liées à sa carrière. Dans une nouvelle conceptualisation de cette analyse, Feldman & Bolino (1996) défendent le point de vue que les ancres de carrière ont des associations les unes avec les autres. Ils proposent un modèle de compatibilité ou d'opposition basé sur le concept des huit ancres de carrière de ScheinCareers that were once conceptualized as life-long linear paths with frequent upward mobility within one organization have increasingly given way to new models of how careers unfold. The organizational rhetoric since the late 1980's has progressively changed from offering long-term and life-long employment, to clear messages concerning the imperative of individual career responsibility for one's progression and development (Bolton & Gold, 1994; Baruch, 2006). In addition, generational differences and technological advances have greatly changed the face of the work place, easily allowing the crossing of borders and the necessity to deal with cultural differences (Crepeau et. al., 2006). To understand how contemporary workers navigate in their careers, we mobilized two main career concepts. First, we used the theory of career anchors developed Schein (1978), which gave rise to wider understanding of both individual differences and organizational culture from an interdisciplinary perspective. Schein postulated that individuals develop a career “self-concept” which becomes an “anchor”, stabilizing and directing individual career decision-making. A re-conceptualization of his work by Feldman & Bolino (1996) postulated that career anchors could be associated with each other, proposing a model of compatibility or opposition in the relationships between the eight career anchors of Schein. Second, we used the boundaryless career concept, which suggested a change from the traditional career ideal of one single employer for the entirety of one's professional life (Arthur & Rousseau, 1996; Sullivan & Arthur, 2006)

Concrete anchors represent an important transition for both the design and construction of a project. Anchors are produced in two main categories: cast-in-place and post-installed. For designers, anchors are used to attach steel members to supporting concrete members. The anchors are designed using the provisions outlined in Building Code Requirements for Structural Concrete, ACI 318-11, Appendix D. These anchors are used to transmit tension and shear forces by using an individual anchor or a multiple anchor group. For contractors, anchor installation marks the transition between concrete and steel construction. Various types of anchors are produced by manufacturers, requiring contractors to be familiar with many installation methods. Careful planning and coordination is necessary to layout and place anchors into their correct location. Once anchors are installed, they must be protected from damage resulting from moving machinery and material. The purpose of this report is to introduce the basics to design concrete anchors by outlining the provisions in ACI 318-11 Appendix D and demonstrating these provisions with design examples. Anchor types, applications and common construction issues important to the structural engineer are also discussed.

Memoria para optar al título de ArquitectoHace ya 30 años que se instauró la figura del Mall en Chile, convirtiéndose en un fenómeno que no ha dejado a nadie indiferente, pues si bien su desarrollo ha sido prácticamente imperceptible para el común de la sociedad, no es menos cierto que ha cambiado, de algún u otro modo, la idiosincrasia del ciudadano chileno. En la actualidad, es una realidad latente e innegable que el Mall es considerado un elemento básico e indispensable para el Chile contemporáneo, llegando al punto de constituir una parte fundamental en el “imaginario de la ciudad”, es decir, a percibirlo como pieza clave que forma parte del contexto social. A pesar de ello, para nuestra profesión es aún un tema tabú, poco discutido, llegando a ser considerado como un espacio no arquitectónico, una estructura “horrorosa” que se empecina en destruir el entorno de la ciudad. Sin embargo, hoy en día, este tema ha generado gran controversia con la llegada del Mall en Castro,Chiloé, construcción que no dejó a nadie exento de opiniones, principalmente por la puesta en peligro de la imagen del patrimonio local dada su imponente morfología. Pese a ello y sumándole las graves falencias urbanas, paisajísticas y, principalmente, legales, el Mall tuvo un gran apoyo por la comunidad chilota, quienes lo consideran como un efecto necesario e imprescindible para el desarrollo local. Es por lo antes mencionado que la empresa que proyectó el Mall de Castro, consideró los deseos y la gran aceptación que el proyecto tuvo entre los habitantes de la Isla, llevándolo a adquirir nuevos terrenos en la zona norte del archipiélago, específicamente en Ancud, con el objeto de construir un inmueble de características similares; no obstante, la construcción tiene como principal falencia, la poca comunicación arquitectónica con la ciudad, pues es un recinto hermético, un espacio indiferente con el contexto chilote. Es en este mismo terreno de Ancud donde ubico el proyecto de título, pues es una oportunidad directa de intervenir en la ciudad, como también es una posibilidad de lograr la articulación entre lo público y lo privado, lo local con lo foráneo, consolidando a la vez la zona comercial, turística, social y urbana más importante de la zona norte de la Isla de Chiloé. Por todo lo anterior es necesario entender que el Mall es un efecto consolidado y que no debemos caer en su rechazo, sino que por el contrario, es indispensable interiorizar y reflexionar sobre este tema; por ello es preciso preguntarse ¿cómo se puede articular un centro comercial de esta tipología en una ciudad con alto carácter como Ancud?

Full textAbstract:
This report is the result from a Master of Science Thesis work at the Royal Institute of Technology, and is executed by technology student Kristina Ahlinder for the behalf of Design Company Top Notch Design AB. Top Notch Design wants to expand their range of marine products and look in to the market of boat anchors. The aim of the project is to develop an anchor for small leisure boats for the Swedish market with focus on usability and safety. A detailed informational study was executed at the beginning of the project. To collect information regarding how potential users experience current anchors on the market, a user test and a digital questionnaire was done. Through the questionnaire, the user test, requirements from the company and the informational study a criteria specification was made. Some of the criteria were that it should be an easy to stow day anchor designed for leisure boats up to 27 feet and have a maximal weight of 8 kg. Other important criteria were good usability and innovative and interesting design. The ideation stage of the project was mainly based upon brainstorming sessions. 11 concepts were sketched and prototyped in paper and wood. Ten of the concepts were manufactured in small-scale and welded together in steel, in order to evaluate the functionality. The anchors were dragged in a sandbox, and the drag-force was measured with a nanometer. The anchor that performed best in the drag test was a kind of foldable plow anchor. This is the concept that was chosen to be developed.The anchor was further developed and tested before being modeled in the CAD-program SolidWorks. The final design consists of a fluke and a shaft connected by a joint, and a handle for usability, ease of recovery and for getting it in the right angle on the seafloor. The anchor has an automatic locking mechanism in the joint, and rubber details. The anchor’s material is mainly aluminum and weighs 3.8 kilos and has a length of 48 centimeters.The anchor fulfills the criteria specification and most of the preferences and according to calculations the joint will hold for forces higher than 2000 N. The anchor will, according to calculations, have an approximate selling price of slightly over 500 SEK. According to feedback given by potential users, 40 % has a good impression of the anchor and 26 % could imagine buying it. The outcome is a new and innovation type of anchor that suits the modern small-boat owner. The anchor has to be tested in full scale with the correct materials to fully be evaluated. The anchor would contribute to the conservative marine market. The anchor would be a brave and interesting addition to the current anchor market, as well as to TND’s current marine products.Denna rapport redovisar resultatet av ett examensarbete vid Kungliga Tekniska Högskolan, utfört av teknologstudent Kristina Ahlinder för företaget Top Notch Design AB. Top Notch Design vill utöka sitt sortiment av marina produkter och undersöka marknaden för båtankare. Syftet med projektet är att utveckla ett ankare för små fritidsbåtar för den svenska marknaden, med fokus på användarvänlighet och säkerhet. En detaljerad informationssökning genomfördes i början av projektet. För att samla in information om hur potentiella användare upplever nuvarande ankare på marknaden utfördes ett användartest och en enkätundersökning. Genom resultat från enkäten, användartestet, krav från företaget samt informationssökningen kunde en kravspecifikation tas fram. Några av kriterierna var att det skulle vara ett stuvbart dagsankare avsett för fritidsbåtar upp till 27 fot och har en maximal vikt på 8 kg. Andra viktiga kriterier gällde avändbarhet och design. Den idégenerering som utfördes i projektet var huvudsakligen baserad på brainstorming. 11 koncept modellerades i papper och trä. Tio av de koncepten tillverkades som skalmodeller i stål för att utvärdera funktionaliteten. Modellerna drogs sedan i en byggd sandlåda och dragkraften mättes med en nanometer. Ankaret som visade sig bäst i dragtestet var ett slags hopfällbart plogankare. Detta var det koncept som valdes för vidareutveckling. Ankaret vidareutvecklades och testades vidare innan det slutgiltiga konceptet modellerades i CAD-programmet SolidWorks. Den slutliga konstruktionen består av ett fly och ett skaft förbunden med en led, samt ett handtag/peke. Ankaret har en automatisk låsmekanism i leden samt gummidetaljer för att förbättra användarvänligheten. Ankaret är huvudsakligen i aluminium och väger 3,8 kilo och har en längd av 48 centimeter.Ankaret uppfyller kravspecifikationen och de flesta av de önskemål som ställts upp. Enligt beräkningar utförda kommer ledens axel att klara krafter högre än 2000 N. Ankaret kommer, enligt beräkningar, ha ett ungefärligt försäljningspris på drygt 500 kronor. Enligt feedback från potentiella användare har 40 % ett bra intryck av ankaret och 26 % kan tänka sig att köpa det. Resultatet är ett nytt och innovativt ankare som passar den moderna småbåtsägaren. Ankaret är ett modigt och intressant komplement till det nuvarande ankarutbudet, liksom till TND nuvarande marina produkter.

Full textAbstract:
.This project is a synthesis of, on the one hand, the interventionist architect curiously and deliberately plotting form and visualising construction and, on the other hand, the human being often wilfully retreated and joyfully observing the uninterrupted and the conflicting. It is this dialectic - rather than immovable theoretical principles - that has informed not only my process, but also my design. In this sense this project represents what I believe to be the most important feature of my architectural education: the inexplicable joy in the constant re-evaluation of the imprecise nexus between the deliberately mediated and the uninterrupted. This impulse is also what (perhaps unknowingly at the time) attracted me to Three Anchor Bay - a site of untameable swells, impenetrable rhythms, ebb and flow. It is a site that necessitates decisiveness in a counterintuitive form; boundaries. Any frontier, however versatile and accommodating, requires commitment (few are capable of confidently kayaking beyond an otherwise parameter-defining promenade). Drawing a line is not only the problem of the architect, but the human being. Although this paper is largely a personal essay instead of a coherent treatise (I reserve the right to remain sceptical of every decision), it is important to make a few general observations. The first is supremely personal: I am decidedly fallible. Although harsh introspection is generally more valuable and courageous than the resolute defence of personal conviction, I often found myself passionately defending lines I have drawn (especially ones that I have spent a lot of time re- drawing and erasing). Redrawing can be a counterintuitive struggle and it has often been difficult to regard it as a necessary and unpredictable process rather than as emblematic of some sort of failure. Although common sense urges us to "learn from our mistakes", it is never quite that simple. This project has, in short, caused me to constantly mediate between conviction and perpetual self-criticism. Secondly, these ideas are by no means new and have been repeated (and often ignored) in various contexts. Karl Popper, for instance, believed that "any idea of Utopia is necessarily closed owing to the fact that it chokes on its own refutations. The simple notion of a good model for society that cannot be left open for falsification is totalitarian” (Taleb, 2004, p.128-129). The same is true of architecture - particularly those projects that are resolutely planted in a pre-determined style, ideology or “balance”.

Mucolli, Gent. "Fuzzy modeling of suction anchor behavior based on cyclic model tests data." Digital WPI, 2016. https://digitalcommons.wpi.edu/etd-theses/1313.
Full textAbstract:
This paper proposes a novel model that can predict the displacement of suction caisson anchors under monotonic and cyclic loading. Failure is assumed to occur when the accumulative monotonic and cyclic displacement along the load attachment point is over 60% of the diameter of the anchor. The anchors will go through lateral failure when the accumulative monotonic and cyclic displacement along the loading direction at the load attachment point is over 30% of the diameter. Hence, it is important to predict this displacement and therefore determine the expected failure of the anchor. However, it is difficult to predict displacement using the modern software without knowing the material properties of the soil and piles. Hence a new model that relies only on the normalized static load (Fa/Ff), normalized cyclic load (Fcy/Ff ), loading angle (Θ), and the number of cycles (N) is proposed. The inputs for training of the proposed model are (Fa/Ff), (Fcy/Ff), (Θ), (α) and (N). The output of the model will be the displacement normalized by the diameter of the anchor. To generalize the trained model, unused sets of data are used to validate the model. Furthermore, a comparative study is performed to evaluate the effectiveness of the proposed model. It is shown from extensive simulation that the model can accurately predict the normalized displacement of suction caisson anchors.

Full textAbstract:
The research objectives for this project were to explicitly define the anchor bolt corrosion problem in the state of Georgia and recommend action to the Georgia Department of Transportation. The bearing assembly of concern is the plate bearing assembly, in which carbon steel and/or bronze plates are anchored by either carbon steel or stainless steel anchor bolts. Inspection report data revealed that anchor bolt corrosion was ubiquitous for all environments in Georgia; the problem was reported for 27% of the steel girder bridges throughout the state. Based on a synthesis of the field investigations, bolt failure analyses, laboratory experimental testing, and review of GDOT inspection report surveys, the corrosion of carbon steel anchor bolts is caused universally by concentration cell corrosion. Other corrosion mechanisms of concern are galvanic and crevice corrosion, which are both enhanced by the current bearing design.
Corrosion protection provided through zinc galvanization cannot sufficiently protect the carbon steel bolt for its entire service life. Corrosion potential and cyclic polarization data confirmed that ASTM Type 304, Type 316, Type 2101, and Type 2205 were protected from concentration cell and localized corrosion in the simulated bearing environment. Therefore, it is recommended that the stainless steel anchor bolts of these types be use in future designs and that the bolts should be electrically separated from all dissimilar metals using a Nylon or Teflon washer to prevent preferential corrosion of carbon steel. It is further recommended that the bronze lube plate should be eliminated entirely and that the bearing type should be a reinforced elastomeric bearing. Maintenance of existing sliding plate bearings should include regular cleaning by brushing away debris from the bearing surfaces, and bridges with carbon steel anchor bolts should be retrofitted to provide additional lateral restraint according to current maintenance procedures.

Full textAbstract:
The topic of this thesis is modeling and simulation of anchor handling vessels. Computer simulations of anchor handling vessels can be used to evaluate the forces acting on them, and to gain valuable insight into their operational limitations. Introductorily, an overview containing important aspects of anchor handling operations is presented. The objective is to highlight important subjects that must be considered before a simulator is developed. A simulator of an anchor handling vessel is successfully implemented in Matlab and Simulink. The simulator contains modules for ballast tanks, anti-roll tanks, cables, seabed and anchor interaction, winch systems and guide pins. The vessel model is matched up against a real anchor handling vessel to give realistic thrust characteristics. The simulator is capable of simulating both anchor deployment and anchor recovery operations in real time. Catenary equations are used to model cables. A quasi-static polynomial approach with look-up tables is used for implementation. The method allows the use of different catenary models to simulate different phases of the anchor handling operation. A catenary model of two cables with a point load, imitating the effect of an anchor, is developed based on existing catenary models in the literature. The simulator is verified through simulations. A set of case studies is used to evaluate the vessel performance during anchor deployment and recovery. The case studies consider operation in ideal and rough weather conditions, and it is shown how equipment failures and poor vessel configuration can lead to decreased vessel stability and loss of maneuvering capabilities.

Full textAbstract:
Piste maps have been used as navigational aids by winter sports enthusiasts for decades. These maps are often hand drawn and are designed to be visually pleasing while still providing an overview of the terrain of a ski resort. As smartphones have become the go-to tool when satisfying our daily navigational needs, the expectations of a digital map have changed. One of these expectations is being able to position yourself and others on the map. With the existing GPS functionality of smartphones, there is a great potential for bringing classical piste maps into the digital age. This project proposes a solution which can position a user given their geographical position on a piste map. The solution includes a process for identifying anchor points which tie geographical coordinates to piste map coordinates, a suitable method of triangulating these points, combined with an algorithm that finds the most suitable triangle to use for finding the transformation parameters, and finally an affine transformation that yields the corresponding piste map coordinates for a given geographical position. The solution also proposes a method to find the smallest but sufficient set size of anchor points for a resort to create a useful and cost efficient model of transformation. The thesis work also presents possible implementations of the positioning algorithm, such as creating a smooth transition between a piste map view and a satellite map view in an Android device. This includes automatic panning and rotation of the satellite map in response to the centering of the piste map on the device screen. Geo-enabling piste maps enables many more interesting applications, such as recording and displaying skiing statistics, providing suggestions of new unexplored areas, keeping track of family or friends, selective location sharing, location-tagged weather and disaster information, and in the wake of the COVID-19 pandemic, providing a user- friendly interface for displaying localized congestion levels.Skidåkare och andra vintersportsentusiaster har använt pistkartor som standarden för navigering i skidorter i flera decennier. Dessa kartor är ofta handritade av en konstnär, och är designade för att vara visuellt tilltalande samtidigt som de förser användaren med en abstraherad översikt av skidanläggningen. När mobiltelefonen tog över våra dagliga navigeringsbehov har också förväntningarna av en digital karta förändrats. En av dessa förväntningar är att kunna positionera sig själv och andra på kartan. Med hjälp av den nuvarande GPS teknologin som finns tillgänglig i mobiltelefoner finns ett stort potential för att vidareutveckling och digitalisering av den klassiska pistkartan. Detta projekt beskriver en digital lösning som kan positionera en användare givet deras geografiska koordinater på en pistkarta. Lösningen består av en process för att identifiera ankarpunkter som binder samman geografiska koordinater och pistkarte-koordinater, samt en metod för att triangulera dessa punkter. Detta är kombinerat med en algoritm som hittar den mest passande triangeln vars transformationsmatris kan användas för att transformera de givna geografiska koordinaterna till pistkarte-koordinater. Lösningen föreslår också en metod för att hitta det minsta tillräckliga antalet ankarpunkter som krävs för att skapa en användbar och kostnadseffektiv transformationsmodell. Examensarbetet föreslår också möjliga implementationer av positioneringslösningen, som att skapa en sammanhängande transition mellan pistkarta och satellit-vy i en Android app. Detta innefattar automatiska förflyttningar och rotationer av satellit-kartan beroende på hur pistkartan är positionerad i relation till skärmens centrum. Positioneringsalgoritmen möjliggör flera andra intressanta tillämpningar, som att visualisera inspelade åk-statistik, ge förslag på tidigare outforskade backar och skidområden, visa upp var vänner och familj befinner sig, selektiv platsdelning, platsrelaterad väder- och snödata, samt förutsättningar för att skapa en användarvänlig visualisering av områdesspecifika trängselnivåer.

Dissertação apresentada à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em ArqueologiaLa présente étude archéologique vise à l’analyse et à la caractérisation de chacune des 44 ancres qui composent le gisement du Parc Archéologique Sous Marin du Cimetière des Ancres de la Baie d’Angra et qui, à ce jour, restent encore méconnues. Nous souhaitons, grâce à une intervention sous-marine systématisée, enregistrer de façon exhaustive toutes les données archéologiques présentes sur le site et sur chacune des ancres, afin d’étudier chaque pièce de façon individuelle. L’objectif de cette première phase de terrain est de proposer une méthodologie permettant de décrire une ancre en contexte sous-marin, en définissant notamment les protocoles de mesures à réaliser. Les éléments constitutifs de la pièce seront ainsi évalués et ses spécificités morphologiques enregistrées (la prise des mesures sera enrichi par des photographies et dessins archéologiques).Nous souhaitons, à l’issue de cette campagne de terrain, réaliser une typologie des ancres de la Baie d’Angra, mettant en évidence l’évolution formelle des amarres au fil des siècles. L’élaboration d’un tel outil d’analyse, couplé à une étude bibliographique exhaustive des traités de construction navale, nous permettra alors de déduire une datation présumée des pièces, ainsi que leur potentielle origine géographique, tout en témoignant de l’évolution des emplois et techniques de fabrication des ancres. L’interprétation de ces données inédites nous aidera à mieux comprendre quels types de navires pouvaient être susceptibles de transporter ces ancres, tout en tentant d’expliciter les raisons ayant pu les pousser à abandonner leurs amarres à cet endroit. Ce sera également l’occasion de mieux appréhender le rôle joué par l’ancien port d’ancrage de la ville d’Angra et plus largement de l’archipel des Açores dans la géopolitique et les échanges internationaux du XVI° au XIX° siècle. Enfin nous prétendons proposer un outil de comparaison susceptible d’aider à l’analyse d’autres sites ou ancres similaires, tout en apportant de nouvelles clefs de valorisation, en vue d’une exploitation plus efficace de ce type de gisement archéologique et de celui d’Angra en particulier. O presente estudo arqueológico visa a análise e a caracterização de cada uma das 43 âncoras que compõem o conjunto do Parque Arqueológico Subaquático do Cemitério das Âncoras da Baia de Angra do Heroísmo as quais, até à data, se encontram por estudar. Desejamos, graças a uma intervenção subaquática sistematizada, registar de forma exaustiva todos os dados arqueológicos presentes no sítio e em cada uma das âncoras, a fim de estudar cada peça individualmente. O objectivo desta primeira fase de campo, será de propor uma metodologia que permita descrever uma âncora em contexto subaquático, definindo os protocolos das medidas à realizar. Os elementos constituintes de cada ferro, serão assim avaliados e as especificidades morfológicas registadas. Após a conclusão dos trabalhos de campo, o objectivo será realizar uma tipologia das âncoras da Baia de Angra, com a finalidade de evidenciar a evolução morfológica das amarras ao longo dos séculos. A elaboração dessa ferramenta de análise, complementada por o estudo bibliográfico exaustivo dos tratados de construção naval, permitirá deduzir uma datação relativa das peças, como também as suas potenciais origens geográficas, testemunhando a evolução dos usos e técnicas de fabrico das âncoras. A interpretação destes dados inéditos ajudaram-nos a compreender melhor quais os tipos de navios que possivelmente transportariam estas âncoras, e quando possível tentar explicar os motivos pelos quais elas foram abandonadas neste contexto particular. Permitirá simultaneamente esclarecer o papel desempenhado pelo antigo porto de ancoragem da cidade de Angra, e de um modo mais abrangente do arquipélago dos Açores, na geopolítica e nos intercâmbios internacionais dos séculos XVI ao XIX. Conclusivamente, pretendemos propor uma ferramenta de comparação susceptível de ajudar a análise de outros sítios ou âncoras similares, tal como trazer novas chaves de valorização para permitir uma rentabilização mais eficiente deste tipo de conjunto arqueológico e do caso de Angra em particular. The present archaeological study aims to the analysis and the characterization of each of the 43 anchors which compose the layer of the Archaeological Submarine Park of the Cemetery of the Anchors of Bay of Angra and which, to date, remain still ignored. We wish, thanks to a systematized underwater intervention, to record in an exhaustive way all the archaeological data present on the site and each anchor, in order to study each part in an individual way. The objective of this first field phase is to propose a methodology making it possible to describe an anchor in submarine context, particularly by defining the protocols of measures to be undertaken. The components of the part will be thus evaluated and its morphological specificities recorded. We wish, at the conclusion of this field work, to carry out a typology of the anchors of Bay of Angra, highlighting the formal evolution of the mooring ropes along the centuries. The elaboration of such a tool for analysis, together with an exhaustive bibliographical study of the treaties of naval construction, will then enable us to deduce a presumable dating for the parts, as well as their potential geographic origin, while testifying the evolution of the uses and techniques of manufacturing of the anchors. The interpretation of these unpublished data will help us to better understanding which types of ships could be likely to transport these anchors, while trying to clarify the reasons that drove them to give up their mooring ropes at this place. It will be also the occasion to better understand the role played by the old anchoring port of the town of Angra and on a larger scale of archipelago of the Azores in the international geopolitics and the exchanges from the 16th to the 19 th century. Finally we claim to propose a tool of comparison likely to help with the analysis of other sites or similar anchors, while bringing new keys of valorization, for a more effective exploitation of this kind of archaeological layer and that of Angra in particular.

Full textAbstract:
Topic modeling is an effective tool for analyzing the thematic content of large collections of text. However, traditional probabilistic topic modeling is limited to a small number of topics (typically no more than hundreds). We introduce fine-grained topic models, which have large numbers of nuanced and specific topics. We demonstrate that fine-grained topic models enable use cases not currently possible with current topic modeling techniques, including an automatic cross-referencing task in which short passages of text are linked to other topically related passages. We do so by leveraging anchor methods, a recent class of topic model based on non-negative matrix factorization in which each topic is anchored by a single word. We explore extensions of the anchor algorithm, including tandem anchors, which relaxes the restriction that anchors be formed of single words. By doing so, we are able to produce anchor-based topic models with thousands of fine-grained topics. We also develop metrics for evaluating token level topic assignments and use those metrics to improve the accuracy of fine-grained topic models.

Full textAbstract:
Inflatable dams are flexible, cylindrical structures anchored to a foundation. They are used for a variety of purposes, e.g. diverting water for irrigation or groundwater recharging, impounding water for recreational purposes, and raising the height of existing dams or spillways.
The vibration behavior of such dams is analyzed. Single-anchor inflatable dams with fins are considered. First, a static analysis is performed which yields the equilibrium shapes of the dam, both in the presence and absence of water. Then, a dynamic analysis is undertaken which analyzes the small vibrations of the inflatable dam about the equilibrium configuration, both in the presence of water (hydrostatic water as well as parallel flowing water) and absence of water.
The dam is modeled as an elastic shell. It is assumed to be air-inflated and resting on a rigid foundation. The cross-sectional perimeter, material thickness, modulus of elasticity, and Poisson's ratio are given. The analysis is performed for different values of internal pressure and external water heads.
Initially, the dam is assumed to lie flat. The internal pressure is then increased slowly until it reaches the desired value. Then the external water is applied and the equilibrium configuration is obtained. Small vibrations about this configuration are considered. The water is assumed to be inviscid and incompressible, and potential theory is used. The infinite-frequency limit is assumed on the free surface. A boundary element technique is utilized to determine the behavior of the water, and the finite element program ABAQUS is used to analyze the structural behavior. Both the cases of fluid at rest and flowing parallel to the dam are considered. The vibration frequencies and mode shapes are computed. The effect of the internal pressure of the dam is investigated, and the results are compared to those for the dam in the absence of external water.

Full textAbstract:
Wireless sensor networks are composed of sensor nodes, which can monitor an environment and observe events of interest. These networks are applied in various fields including but not limited to environmental, industrial and habitat monitoring. In many applications, the exact location of the sensor nodes is unknown after deployment. Localization is a process used to find sensor node's positional coordinates, which is vital information. The localization is generally assisted by anchor nodes that are also sensor nodes but with known locations. Anchor nodes generally are expensive and need to be optimally placed for effective localization. Passive localization is one of the localization techniques where the sensor nodes silently listen to the global events like thunder sounds, seismic waves, lighting, etc. According to previous studies, the ideal location to place anchor nodes was on the perimeter of the sensor network. This may not be the case in passive localization, since the function of anchor nodes here is different than the anchor nodes used in other localization systems. I do extensive studies on positioning anchor nodes for effective localization. Several simulations are run in dense and sparse networks for proper positioning of anchor nodes. I show that, for effective passive localization, the optimal placement of the anchor nodes is at the center of the network in such a way that no three anchor nodes share linearity. The more the non-linearity, the better the localization. The localization for our network design proves better when I place anchor nodes at right angles.

In this paper I present ANCOR Dashboard, a front end web framework that interfaces with ANCOR. ANCOR Dashboard aims to provide ANCORs users with an easy to use front end interface for accomplishing various use-cases against the ANCOR framework. ANCOR Dashboard was developed mainly in AngularJS, a lightweight JavaScript framework. This dashboard is able to accomplish everything that the ANCOR Command Line Interface, or ANCOR-CLI, is able to do. This framework also needed to provide some information about the state of the system through various data gathered from ANCOR in a human readable format. Not only should it be able to inform the user about the state of ANCOR but it needs to be able to perform operations against ANCOR just like the command line interface can do.This report documents the design and implementation of ANCOR Dashboard. It will detail the necessary background of the project, and overview of the framework, and discus- sion of implementation and component breakdown. I will also provide an evaluation of the dashboard and a discussion about future work with ANCOR Dashboard.

Full textAbstract:
Human identification systems are commonly used for security issues. Most of them are based on ID card. However, using an ID card for identification may not be safe enough since people may not have any protection against the theft. Another solution to the identification problem is to use iris or fingerprints. However, systems based on the iris or fingerprints need close interaction to identification machine. Identifying someone from his photograph overcomes all these problems which can be called as face recognition.
Common face recognition systems are based on the 2D image recognition but success rates of these methods are strictly depending on the environment. Variations on brightness and pose, complex background are the main problems for 2D image recognition systems. At this point, three dimensional face recognition techniques gain importance. Although there are a lot of methods developed for 3D face recognition, many of them assume that face is not rotated and there is not any destructive (i.e. beard, moustache, hair, hat, and eyeglasses) on the face. However, identification needs to be done though these destructives. Basic step for the face recognition is the determination of the anchor points (i.e. nose tip, inner eye points). In this study, the goal is to implement previously proposed four face recognition methods based on anchor point detection&ldquo

Full textAbstract:
Double-nut anchor bolt systems are used in the erection of traffic signal poles, high-mast luminaries, and other highway appurtenances. An absence of a tightening standard for such systems decreases the confidence in their performance under fatigue loading. Past research has shown that a tightening standard should include the development of preload in the anchor bolt sufficient to provide adequate resistance to fatigue failure. Preload should be measured by a turn-of-the-nut method.
Laboratory progressive tightening tests were performed in order to monitor the stress ranges occurring in the bolt at various locations of interest at various degrees of turn-of-the-nut tightness. Tests were performed on six diameters of anchor bolt ranging from 1 to 2-1/4 inches in diameter and two different categories of thread pitch: UNC and 8UN. Plots of stress range versus degree of tightness were developed for each test and evaluated to find the minimum degree of turn-of-the-nut at which stress range inside the nuts dropped below that outside the nuts. This shift was considered to be the principle theoretical indication of adequate performance. A fatigue test which saw failure outside the double-nut connection was set down as the practical indicator of adequate fatigue performance.
The 2 inch 8UN bolt was chosen as the critical specimen due to its overall low generation of preload during tightening tests. Theoretical testing showed that 1/24 turn-of-the-nut would guarantee sufficient fatigue performance. Two practical fatigue tests of the bolt at that tightness saw one positive and one negative failure.
After actual lab tests, finite element modeling was used to investigate the behavior of the bolt. It was found that performance did not see improvement until 1/12 turn-of-the-nut.
After all results were considered, a standard of 1/6 turn-of-the-nut or refusal of tightening by specified methods was recommended, provided a minimum of 1/12 turn-of-the-nut was achieved. This value allows for ease of measurement, sufficient tightness, degree of safety, and has been shown in past testing not to cause failure through over-tightening. However, tightening to only 1/12 turn-of-the-nut still provided adequate performance.

Resumo: Agitação e mistura são o coração da indústria química, e provavelmente os equipamentos para esses fins são os mais antigos que se possa imaginar quando se fala em processamento de matérias primas visando-se a obtenção de produtos. Devido à sua grande importância para a indústria, os processos vem se desenvolvendo ao longo do tempo e, nas últimas décadas, técnicas computacionais tem sido utilizadas para o projeto e otimização desses equipamentos. Em especial destaca-se a fluido-dinâmica computacional - CFD (Computational Fluid Dynamics). Este trabalho tem como objetivo a aplicação de técnicas de CFD para o estudo de sistemas com agitadores tipo âncora, utilizados em geral para fluidos altamente viscosos e, portanto com alto consumo de energia. O estudo por sua vez, através do entendimento dos fluxos no interior do tanque, tem como objetivo propor soluções e modificações a fim de melhorar a mistura e minimizar o gasto de energia no processo. O pacote computacional CFX 4.4. foi empregado como ferramenta de CFD para a realização dos estudos contidos neste trabalho, tendo sido obtidos resultados esclarecedores dos fenômenos envolvidos e coerentes com os dados experimentais disponíveis em literatura. Conclui-se que as ferramentas utilizadas são apropriadas para o estudo de tanques agitados e que possibilitam tanto o projeto como também a otimização de sistemas existentes, com economia de tempo e dinheiro. Quando comparada à técnicas experimentais, a técnica provou fornecer resultados precisos e confiáveis. A sugestão para estudos futuros é o cálculo simultâneo de reações químicas, para o entendimento de reatores químicos, especialmente em reações onde a viscosidade varia com o tempo
Abstract: Stirred vessels and mixing systems are the core of the chemical industries, and probably they are the oldest equipment in chemical processing for desired products. Due its great importance to the industry, these processes have been developed through the time, and in the last decades, computational techniques have been used in the project and optimization of these equipments. Particularly the Computational Fluid Dynamics - CFD. The objective of this work is to apply CFD techniques in the study of systems agitated by anchor impellers, generally used for higWy viscous fluids and therefore with high power consumption. The study has the objective to propose changes in the system so mixing can be optimized and the power consumption minimized, through the understanding of the flow pattems inside the tank. The computational package CFX 4.4. has been used as a CFD tool to generate the numerical results, which are useful to clarify the phenomena and are coherent with experimental data available in the literature. The study showed that the tools that have been used are appropriated to the study of stirred vessels and are able to design new systems and optimize actual systems, leading to money and time saving. .When compared to experimental techniques, the tools used showed that it is able to provide precise and reliable results. The suggestion for future studies is the simultaneous calculus of chemical reactions, which can lead to a better understanding of chemical reactors, especially those in which viscosity varies along time

Full textAbstract:
Topic models are useful tools for exploring large data sets of textual content by exposing a generative process from which the text was produced. Anchor-based topic models utilize the anchor word assumption to define a set of algorithms with provable guarantees which recover the underlying topics with a run time practically independent of corpus size. A number of extensions to the initial anchor word-based algorithms, and enhancements made to tangential models, have been proposed which improve the intrinsic characteristics of the model making them more interpretable by humans. This thesis evaluates improvements to human interpretability due to: low-dimensional word embeddings in combination with a regularized objective function, automatic topic merging using tandem anchors, and utilizing word embeddings to synthetically increase corpus density. Results show that tandem anchors are viable vehicles for automatic topic merging, and that using word embeddings significantly improves the original anchor method across all measured metrics. Combining low-dimensional embeddings and a regularized objective results in computational downsides with small or no improvements to the metrics measured.

Full textAbstract:
Plasmodium falciparum est responsable de la forme la plus grave de paludisme avec plus de 600 000 décès par an. L'absence de vaccin efficace, combinée à l'émergence de résistances aux traitements récurrents, exige le développement de nouvelles molécules. Afin de limiter ces résistances, il est nécessaire de cibler de nouvelles voies métaboliques indispensables à la survie du parasite. Ce travail de thèse repose sur l'étude de deux voies métaboliques essentielles au parasite que sont la voie de recyclage des bases puriques et la voie de biosynthèse des ancres glycosylphosphatidylinositol (GPI).En ce qui concerne la voie de recyclage des bases puriques, la détermination des structures cristallines de l' « IMP specific 5‘-nucleotidase » (PfISN1) associée aux études biochimiques et biophysiques (SAXS, EM, MALS…), a permis de préciser le mécanisme d'action fournissant ainsi une base solide pour la mise au point d'inhibiteurs. Une banque de plus 3000 composés a été criblée par Fluorimétrie à Balayage Différentiel et les effets des molécules sélectionnées seront évalués sur l'enzyme et sur la croissance du parasite en culture.Quatre cibles thérapeutiques potentielles appartenant à la voie de biosynthèse des ancres GPI ont été sélectionnées. L'utilisation de plusieurs systèmes d'expression disponibles au laboratoire (bactérie, levure, acellulaire en germe de blé) ou via des plateformes européennes pour l‘expression en cellules de mammifères HEK293T (Oxford), de cellules BHK21 transfectées avec le virus de la vaccine modifié, T7-MVA, (Strasbourg) ou la plateforme ESPRIT (Grenoble) ont permis de passer outre les difficultés rencontrées pour exprimer les protéines d'intérêt. L'une des quatre cibles, la mannose-1-phosphate guanylyltransférase (PfMPG), a pu être exprimée de manière suffisante quantitativement et qualitativement pour une caractérisation biochimique et structurale. Une analyse par SAXS et cristallographie aux rayons X a été réaliséePlasmodium falciparum is responsible for the most severe form of malaria with more than 600,000 deaths per year. The lack of an effective vaccine, combined with the emergence of drug resistant parasites, necessitates the development of new drugs. In order to limit these resistances, it is necessary to target new metabolic pathways essential for parasite survival. This thesis work is based on the study of two metabolic pathways essential to the parasite, the purine salvage pathways and the glycosylphosphatidylinositol (GPI) anchor biosynthesis pathway.Concerning the purine salvage pathway, the determination of the crystal structures of the IMP -specific 5'-nucleotidase (PfISN1) associated with biochemical and biophysical studies (SAXS, EM, MALS, etc.) have allowed to propose a reaction mechanism, thereby providing a solid basis for the conception and development of inhibitors. A library of more than 3000 compounds was screened by Differential Scanning Fluorimetry and the selected molecules will be evaluated for their inhibitory effect on the enzyme and on the growth of parasites in culture.Four potential therapeutic targets belonging to the GPI anchor biosynthesis pathway were selected. The use of several in-house available expression systems (bacteria, yeast, and acellular wheat germ) as well as European platforms for the expression in HEK293T mammalian cells (Oxford), in BHK21 cells transfected with the modified vaccinia virus, T7-MVA, (Strasbourg) or the ESPRIT platform (Grenoble) has allowed us to overcome the difficulties encountered on obtaining the selected protein targets. One of the four targets has been expressed in sufficient amount and quality for biochemical- and structural characterization, namely the mannose-1-phosphate guanylyltransferase (PfMPG). SAXS and X-ray crystallography analyses have been carried out

Full textAbstract:
Renewable energy is likely to be of great importance in decades to come due to increased energy consumption. Kinetic energy from wind is expected to cover a part of this need, and wind farms are so far built onshore or at shallow water. On the other hand wind turbines are not always wanted close to land due to both the visual aspects and bird life. An alternative may therefore be to place wind turbines offshore. However, large water depths are causing problems for existing bottom fixed structures and floating wind turbines may therefore be a solution. In this thesis feasibility of tension leg anchor systems for floating wind turbines is investigated. A literature study including tension leg principles, relevant load parameters and methods for calculating motions on tension leg structures are looked into. Preliminary calculations of motion based on a one degree of freedom model are coded and executed in Matlab. Finally, a model in scale 1:100 has been built and further exposed to regular waves in a laboratory test. Numerical and experimental results are investigated and compared for different wave parameters in order to reveal potential weaknesses of the concept. Numerical and experimental results coincide quite well for structure motion in the wave direction, and in most cases the structure get small motion amplitudes which generate negligible vertical motions in form of set down. The overturning moment calculations also coincide well, and show that there are limitations in the mooring feasibility when exposed to large waves. The pretension is proven to be a very important parameter for the concept. Measurement of tendon forces from laboratory test show that the model is loaded differently and in larger order of magnitude than expected. For the scaled model a simplified tendon attachment arrangement in form of a steel plate is used. The strange force distribution may therefore represent loading on this plate. The results however show that tension leg anchoring can be a relevant alternative type of anchor system for floating wind turbines if sufficient system pretension is obtained. In addition, if also a reasonable magnitude and distribution of mass are obtained, the structure is expected to handle quite large waves. The design presented in this thesis is far from optimized. For further work it is therefore advised to model the structure in software where structural analysis can be executed in order to decide upon an optimized structural weight, seeing this as an important parameter.

Full textAbstract:
Wireless sensor networks allow us to instrument our world in novel ways providing detailed insight that had not been possible earlier. Since these networks provide an interface to the physical world, it is necessary for each sensor node to learn its location in the physical space. The availability of location information at individual sensor nodes allows the network to provide higher layer services such as location stamped event reporting, geographic routing, in-network processing etc. A wide range of these sensor network protocols do not require absolute node coordinates and can work with relative node positions. This motivates for the need of anchor free localization algorithms that localize the individual sensor nodes with respect to each other in a local coordinate system. Such algorithms allow the sensor networks to be decoupled from external infrastructure and become truly place and play systems. The primary contributions of this thesis include two anchor free localization algorithms and one location refinement algorithm for ad-hoc wireless sensor networks. Our distributed anchor free localization algorithms do not require any external infrastructure in the form of landmark or manually initialized anchor nodes. These algorithms use measured inter-node distances among some node pairs and localize the entire network in a local coordinate system up to a global translation, rotation and reflection. The relative or virtual coordinates assigned by these algorithms can be readily used with a range of sensor network services like geographic routing, data aggregation, topology control etc. Our first localization algorithm is based on a distributed collaborative approach where all of the nodes in the network collaborate with each other to select a set of nodes. These nodes are localized and then used as reference nodes for the remaining sensor nodes. The novelty of this approach is that instead of solving the localization problem for the entire network upfront, first a small well-formed localization problem is solved and then these results are used to solve the localization problem for the remaining nodes in the network. Our second localization algorithm borrows ideas from the data visualization field and exploits the general undirected graph drawing theory to solve the sensor network localization problem. This algorithm divides the network into a large number of small overlapping clusters and creates local coordinate systems for each of the clusters. These clusters are then merged together in a single coordinate system using a novel distributed algorithm that seeks to minimize the error during this merge process. Our final contribution is a distributed location refinement algorithm that can be used with any of the range based localization algorithms to refine the sensor node coordinates to conform to the measured inter-node distances. We model this coordinate refinement problem as an unconstrained non-linear optimization problem and then transform this optimization problem into an aggregate computation problem. We propose two different approaches to solve this aggregate computation problem in a distributed manner. We evaluate our algorithms with detailed simulations using both Matlab and TinyOS simulator TOSSIM. We also validate our simulation results with experimentation carried out on a real network of MIT Cricket motes. We conclude this thesis with lessons learned during this research and discuss some future directions which can be explored to advance the research in sensor network localization.

Ancrer l'interaction: Gestion des connaissances pour la robotique interactive Avec le développement de la robotique cognitive, le besoin d'outils avancés pour représenter, manipuler, raisonner sur les connaissances acquises par un robot a clairement été mis en avant. Mais stocker et manipuler des connaissances requiert tout d'abord d'éclaircir ce que l'on nomme connaissance pour un robot, et comment celle-ci peut-elle être représentée de manière intelligible pour une machine. Ce travail s'efforce dans un premier temps d'identifier de manière systématique les besoins en terme de représentation de connaissance des applications robotiques modernes, dans le contexte spécifique de la robotique de service et des interactions homme-robot. Nous proposons une typologie originale des caractéristiques souhaitables des systèmes de représentation des connaissances, appuyée sur un état de l'art détaillé des outils existants dans notre communauté. Dans un second temps, nous présentons en profondeur ORO, une instanciation particulière d'un système de représentation et manipulation des connaissances, conçu et implémenté durant la préparation de cette thèse. Nous détaillons le fonctionnement interne du système, ainsi que son intégration dans plusieurs architectures robotiques complètes. Un éclairage particulier est donné sur la modélisation de la prise de perspective dans le contexte de l'interaction, et de son interprétation en terme de théorie de l'esprit. La troisième partie de l'étude porte sur une application importante des systèmes de représentation des connaissances dans ce contexte de l'interaction homme-robot : le traitement du dialogue situé.

Full textAbstract:
The career anchors concept is an approach to understanding career orientation and motivation. The original career anchor model was introduced by Schein in 1974. Several investigators have created revisions of the model to make it more useful. This dissertation is a continuation of the quest to evaluate the original model and the revised models with respect to empirical support. This study is the first of two studies in which measurement methods are devised to solve the psychometric problems of previous measures. In this study we create and test an "economic exchange" model to correct the problem of acquiescent bias. We test five career anchor models and this new scaling method against two sets of data. The first consists of data from 330 participants we collect in the present study, and the other is a set of correlation matrices from Barclay's dissertation meta-analysis of six previous studies from the literature. We find that the economic exchange method creates greater variances in the ratings (both within each person and across persons) as predicted, but the hypothesis of predicted increase in the range of correlation coefficients for this method is not supported. In its present form the economic exchange method is not found to be superior to the standard Likert scale method. In addition, the oppositionality of career anchor choices does not increase for older respondents as expected. From a confirmatory factor analysis test of goodness of fit of the five models against the six datasets of this dissertation and the six studies from Barclay's meta-analysis, we find no evidence for one best career anchors model. That is, the five competing theoretical models seem to each be "best" in some situations or populations.

Full textAbstract:
An important aspect of upcoming fifth-generation (5G) cellular communication systems is to improve the accuracy with which user equipments can be positioned. Accurately knowing the position of a user equipment is becoming increasingly important for a wide range of applications, such as automation in industry, drones, and the internet of things. Contrary to how existing techniques for outdoor cellular positioning deal with multipath propagation, in this study the aim is to use, rather than mitigate, the multipath propagation prevalent in dense urban environments. It is investigated whether it is possible to position a user equipment using only a single transmitting base station, by exploiting position-related information in multipath components inherent in the received signal. Two algorithms are developed: one classical point-estimation algorithm using a grid search to find the cost function-minimizing position, and one Bayesian filtering algorithm using a point-mass filter. Both algorithms make use of BEZT, a set of 3D propagation models developed by Ericsson Research, to predict propagation paths. A model of the signal received by a user equipment is formulated for use in the positioning algorithms. In addition to the signal model, the algorithms also require a digital map of the propagation environment. The algorithms are evaluated first on synthetic measurements, generated using BEZT, and then on real-world measurements. For both the synthetic and real-world measurement sets, the Bayesian point-mass filter outperforms the classical algorithm. It is observed how, given synthetic measurements, the algorithms yield better estimates in non-line-of-sight regions than in regions where the user equipment has line-of-sight to the transmitting base station. Unfortunately, these results do not generalize well to the real-world measurements, where, overall, neither algorithm is able to provide reliable and robust position estimates. However, as multipath-assisted positioning, to the best of our knowledge, has not been used for outdoor cellular positioning before, there are plenty of algorithm extensions, modifications, and problem aspects left to be studied - some of which are discussed in the concluding chapters.

Full textAbstract:
Suture or bone anchors are used to reattach a tendon or ligament after it has been torn away from the bone. Anchors provide secure attachments to bone during trauma or reconstructive surgery, holding the ligament or tendon in place and potentially allowing greater mobility during recovery. Computer modelling techniques are used to investigate both established bone anchor technology, such as threaded implants, and emerging technologies such as cement augmentation or sonic-fusion. Sonic fusion is an ultrasound-assisted anchoring method which has recently been introduced in low load maxillofacial applications, and is expected to be used in other low load applications such as hallux valgus alignment procedures and suture attachment. Threaded anchors were examined using two Finite Element (FE) models of human cancellous bone, representing both “normal” and “weaker” bone. Simulation and analysis revealed the critical nature of modelling the microstructure of bone. Changing the direction of loading in the model leads to significant changes in the response of the construct, and this cannot be represented in continuum models, or in physical models using artificial cancellous bone. Rapid prototyping (RP) using 3d printing was used for validation of the FE models. While this method has previously been implemented to create physical bone models, testing an assembly model and comparing it to FE results for inclined loading had not been attempted. RP models were created of the threaded anchor in both “normal” and “weaker” bone, and a sonic fusion model in the normal bone was also created. These models were then subjected to mechanical testing. Results produced from the simulation correlated with the physical results. The importance of a cortical layer was re-confirmed. At the apparent densities simulated, engagement with the cortical layer increases pull-out force dramatically. Engaging the anchor even with a thin cortical layer can produce a significant improvement to pull-out strength. Novel sonic fusion FE models were created from a CT scan of animal bone, and the geometry for both the sonic-fusion pin and bone were taken from the CT scan. Computer generated geometry was used to build pin concepts of varying shapes. It was shown that if good engagement is made with bone, as in the case of all of the concepts created, then sonic fusion can produce a good holding power - comparable with that of a threaded anchor. The results showed that sonic-fusion requires less drill penetration into the bone, meaning less of the inherent bone structure is removed – vital for patients with poor bone quality. Bone cement models were investigated. Bone augmentation models were created, and the addition of cement demonstrated an improvement in anchor holding power. The research showed that there are benefits to using FEA as a tool to evaluate the mechanical aspects of cement distribution. The results proved the hypothesis that augmentation will likely increase the holding power of anchor, and its distribution will affect pull-out significantly. This work has created a method for modelling and evaluating both established and novel bone anchor technology in CT bone geometry, a procedure which could be expanded to other bone implants. It has been validated using the innovative approach of rapid prototyping.

Due to recent fractures in grade 70 anchor chains in the fish farming industry, chain supplier Erling Haug AS has initiated an examination of a sandblasted anchor they sell today. The sandblasted anchor chain is of the same strength category as the chains associated with the mentioned accidents. The mechanical properties of the sandblasted chain were characterized in 2010 in a student project work[1]. The report expressed concern about the sandblasted grade 70 chains since the material fulfilled requirements to be susceptible to hydrogen induced stress cracking (HISC). Therefore, further research on the material was needed. Another grade 70 chain, of an unknown origin, was obtained to make a comparison. This chain had fractured in-service. It was therefore necessary to characterize the mechanical properties of the fractured chain before examining the two chain grades susceptibility to HISC. The fractured chain was examined in terms of its microstructure, hardness, transition temperature and strength. An attempt was made to explain why the fractured chain failed in-service.The tensile test of the fractured chain revealed that its yield strength was 140MPa lower than that of the sandblasted chain. It was considered possible that the fracture chain were weaker than they should have been and that the reason it failed in-service was due to overload.The susceptibility of the two chains to HISC was tested by submerging tensile specimens into a 3.5% NaCl solution in CorTest Proof rings, while exposed to hydrogen. Specimens were either hot dip galvanized (HDG), protected by an external potential of -1050mV vs. Ag/AgCl or freely exposed at their corrosion potential. Some specimens were pulled in steps till fracture, while others were held at a constant load for 14 days.Different loading and corrosion potentials were applied to the two chain qualities during the HISC test, but the experiment was unable to provoke brittle fractures in either of them. No cracking was observed in the SEMivfor any of the HDG tensile specimens. It was found that hydrogen have no influence the mechanical properties of the HDG tensile specimens, while hydrogen appear to assist in the development of cracks on the polarized specimens.

Full textAbstract:
In the last decades, considerable improvements have been achieved in the seismic design of buildings thanks to the implementation of concepts such as ductility and energy dissipation. Consequently, new structures are not only able to perform better during seismic events, but are also more efficient in terms of balance between life safety and costs. Conversely, historic centres are still considerably affected by earthquakes. To understand the extent of seismic-related damage in historic centres, it may suffice to think that the ICOMOS World Report 2008-2010 on Monuments and Sites in Danger reports no less than five earthquakes, Chile 2010, Sichuan 2008, Haiti 2010, L’Aquila 2009 and Christchurch 2010, all of which impacted and endangered heritage buildings and assets. The lack of good quality connections among structural elements greatly affects the dynamic performance of heritage masonry structures and is the cause of out-of-plane failures of masonry panels, which are most frequently recurring, most dangerous in terms of human lives and most damaging from the point of view of conservation. Although it is recognised that the strengthening of connections is of capital importance for damage reduction and prevention, ad-hoc solutions are missing from the technical literature. Furthermore, design codes are vague when it comes to define the assessment and design procedures to be followed when implementing innovative strengthening system in historic structures. This dissertation aims to tackle such technical gaps by developing a new strengthening system and compiling a draft protocol for its validation and design. Two typologies of dissipative devices are designed to address the out-of-plane mechanisms of wall panels and limit cracking in the historic substratum, in accordance with both the principles of multilevel performance design and of the preservation of historic assets. The prototypes are validated through experimental assessment, on-site application to a case study and computational modelling. The recurring structural features and issues surveyed in the aftermaths of major seismic events feed into the validation process; the weakness of historic structural connections, the characteristics of original materials, traditional construction techniques as much as current practice are all taken in due consideration. Throughout the validation process, great importance is given to the relevance of experimental and computational results to the task of creating a systematic process, which can provide guidance to those facing the challenge of creating and implementing innovative structural solutions through a broad variety of methodologies. The research project contributes to the collection of quantitative data and, even more importantly, it amounts to a first step towards the development of validation and design procedures. These, although not exhaustive of the broad variety of scenarios typical of heritage structures, constitute the basis for further developments and research challenges, as highlighted in the conclusions. Ultimately the thesis aims to address the missing link between research, market and practice. In spite of the peculiarities and limits of each case, research should indeed strive to provide targeted, yet flexible solutions that end users will be able to apply in compliance with the requirements of current codes.

Both numerical analyses and field tests were accomplished to elucidate the anchorage behavior of frictional anchor groups in gravel. A series of triaxial tested results was adopted, based on the constitutive model for the cohesionless soil that named SHASOVOD (A continuous strain hardening-softening and volumetric dilatancy model), to obtained the parameters of the model. In conjunction with FLAC3D software, behaviors of single anchors and anchor groups in gravel were analyzed. In addition, to verify the suitability of the numerical program, filed tests on the single anchor and the dual anchors were conducted within an excavating site of gravel. A succession of parametric analyses was carried out to study the anchorage behaviors of single anchors and anchor groups in gravel formation. According numerical results, the load-displacement relationship and the ultimate load analyzed numerically agree closely with those determined from field test measurements not only for the single anchor but also for the dual anchors. When a 2*2 anchor group with a spacing Sh of 6.5D (D: anchor diameter), the efficiency of the anchor group was calculated to be only 53%~ 84%. As the Sh was 13D, the efficiency of an anchor group could more than 90%, even there is no obvious interference. The yielding zone of the anchor group increases as the overburden depth increases. The interference of a 2*2 anchor group decreased with an increase in overburden depth, but increased with an increase in fixed length. However, interference can be eliminated as the anchor spacings greater than 26D. It can be found from the numerical results, the interference of a 3*3 anchor group is greater than that of a 2*2 anchor group.

In Western, many television networks always expend largely to mold the star anchor for raising rating. They believe that the more attractive the anchor’s image, the higher the rating. Since the first cable television station has established in Taiwan in 1993, the competition among television stations to attractive the audience become intense. The way to make up anchor’s image is changed; we can read anchor’s stories in newspaper in various ways. General speaking, the only one purpose for publicizing is rating. The main purpose of this study is in connection with news report and anchor’s image. The experimental design is to figure out audiences’ reactions between different newspaper contents (the love & marriage life news and the family life news) and the different aspects (the positive, the negative and the neutral reports). Therefore, the study will also focus on the relationship between anchor’s image and audiences’ television news choices. The study uses questionnaire to collect the data and infers the following results: 1.News report is remarkable to influence anchor’s image. 2.The news report about anchor’s love and marriage has the stronger influence with anchor’s image than the news report about anchor’s family life. 3.It influences with anchor’s “personal glamour”, “professional ability to cover news item”, “trusty” and “authoritative” when audiences read the news report about anchor’s love and marriage. 4.The audiences’ imaging evaluations for the news anchor that come from” negative report” is apparently higher than other evaluations (which come) from positive and neutral reports. 5.There is the highly positive relationship between the imaging index of the news anchor and the intention of the audience.

Corrosion of ground anchors had caused many failures of tied-back slope in Taiwan. To deal with the corrosion problem of anchors, the Taiwan Geotechnical Society suggested that the seal between fixed and free ends of ground anchor be removed from the tendon assembly. The behaviour of anchors with seal removed was examined with suitability test procedure and good anchorage results were observed. To facilitate the process of filling up the annular space outside the plastic sheath and under the anchor head, a specially designed bearing plate assembly is used here. The effectiveness of this fill up grouting can be visually inspected from the bearing plate assembly. An electrical resistance test on the complete anchors confirmed the integrity of corrosion protection measures. A simple and reliable method for measuring the long-term load changes of ground anchors was studied also. This method operates in a similar concept to that of the tell-tale load cell. It only requires the components used in a typical anchor assembly and consists of only one extra strand as the reference strand, which is not engaged by the anchorage. The suitability of this method was confirmed by stressing tests performed on field anchors. Finally, the accuracy of load cell measurement can be significantly improved by using positioning screws on the bearing plates to ensure the alignment of the stressing assembly including the load cell, hydraulic jack, and anchor head.

The trajectory and capacity are key components of the design of drag embedment anchor and drag-in vertically loaded anchors. This experimental testing program quantifies two factors that describe the anchor trajectory and capacity: the equilibrium bearing factor (Ne) and the tangential bearing factor (Ne). These factors can aid in the development of a numerical model of anchor behavior. A magnetometer device is used to track the orientation and location of the anchor during drag embedment. The results of the experimental testing program were compared with the results from a predictive model. The experimental program consisted of drag embedment tests with various testing conditions including different anchor line diameters and different initial pitch orientations. The results with the different anchor lines indicated that thinner anchor lines cause the anchor to dive deeper in the soil. The different initial pitch results indicate that regardless of the initial pitch of the anchor, the anchor rotates to a unique pitch trajectory within 2 fluke lengths.text

There have been many researches proved that the cluster of research or the cooperation between school and company can increase the efficiency of R&D. That’s why many nations encourage the happening of cluster to enhance the nation’s competitiveness. But if there is an activity can help the process of cluster more efficient and effective? Agrawal and Cockburn (2003) developed anchor tenant hypothesis who test anchor tenant can enhances the regional innovation system such that local university research is more likely to be absorbed by and to stimulate local industry R&D. In this research, we use patent counts to measure industrial R&D, use publication counts to measure university research activity. We separate Taiwan into seven metropolitan areas, and correct the data from 1994~2002. We define the anchor tenant as “In Taiwan, the listed electrical firm with at least one patent from the set of specified technology, and at least 500 patents granted to that firm.” After the analysis we conclude that1. The research activity in information technology industry is not evenly dispersed across Taiwan. The counts of patents and papers are highly concentrated within Taipei-Keelung area and HsinChu area.2. The co-location exist between university research and industrial R&D in a given technology across seven metropolitan areas.3. The existence of anchor tenant will help the efficiency and effect of industrial R&D.4. There is no obvious evidence to say that anchor tenant can enhance the regional research system.
