Texto completoNum mundo industrial cada vez mais competitivo, onde a produção de bens de consumo é constante e o seu ritmo de produção aumenta diariamente, não se aceita nada mais que a pura “perfeição”. É cada vez exigida mais e melhor “performance” do factor humano (representando uma peça fundamental para o funcionamento das industrias) e, os índices de produtividade e de qualidade exigem do trabalhador melhores ritmos de trabalho para que os sistemas automatizados e/ou robotizados tenham um desempenho cada vez mais eficiente. O problema está numa economia de mercado onde a alta produção aliada à qualidade é factor determinante para a sobrevivência da indústria. Devido a esta crescente pressão sobre o factor humano, a indústria tem recorrido à ciência para optimizar este factor, pois é reconhecido que o bemestar de um trabalhador pode condicionar o produto final de uma empresa industrial. Esta investigação é uma contribuição que pretende mostrar que é possível conhecer, numa indústria de grande dimensão, valores de conforto / desconforto em locais onde estão localizados postos de trabalho. São apresentados alguns estudos de caso em diferentes dias e são consideradas as zonas de maior vulnerabilidade. Os resultados obtidos foram valorizados através da aplicação de diferentes índices térmicos de aplicação fácil e através das orientações traçadas pelas ISO 7726/1984, 7730/2005 e ANSI/ASHRAE 55/2004. Também se realizou, num local diferente, um estudo em que se aplicou um balanço energético ao ser humano e valorizou-se valores publicados na literatura da especialidade. Os resultados obtidos mostraram que a metodologia usada é correcta e contribuíram para um melhor conhecimento dos padrões que afectam uma nave industrial e, suscitaram estratégias de intervenção para a melhoria do espaço onde trabalhadores estão presentes.
In an industrial world increasingly competitive where the production of consumption goods is constant and the pace of production increases every day and where cannot be accepted nothing more than sheer “perfection”. It’s increasingly demanded more and better “performance” from the human factor (represents a key factor to the industries function) and the indexes of productivity and quality require from the worker better work rates so that the automated systems and / or robotic systems can have an increasing performance. The problem lies in a market economy where high production is based on quality factor for the survival of the industry. Due to this increasing pressure on the human factor the industry has used science to optimize this factor, because it’s recognized that the welfare of a worker may condition the industry end product. This research is a contribution that aims to evaluate, in a large dimension industry, values of comfort / discomfort in places where jobs are located. There are presented some case studies on different days and are considered the most vulnerable areas. The results were valued through the application of different thermal indices of easy application and through the guidelines of ISO 7726/1984, 7730/2005 and ANSI/ASHRAE 55/2004. It was made also, in a different place, a study in which an energy balance was applied to the human being, and values published in the literature of the specialty were taken into consideration. The results show that the methodology was correct and contributed to a better understanding of the patterns that affect an industrial building and sparked intervention strategies to improve the area where workers are present.

Texto completoThe present research project is entitled "Evaluation of the seismic performance of a mining steel building according to ATC-40" and has the purpose of determining the seismic performance of a mining building defined in the technical report ATC-40. The application of a static nonlinear analysis to the computational model of an existing structure can determine the level of damage and the expected seismic performance. Accordingly, the nonlinear static analysis was successfully applied to the model of an existing structure using SAP2000 software, and through data and graphics provided by the program, the level of damage in the industrial building subjected to great seismic actions was determined. This thesis is divided into seven chapters: the first chapter cover the introduction and the importance of the thesis. The second chapter include the generalities, general objectives and specific objectives of the thesis project; the third reviews the Pushover analysis theoretical framework; the fourth shows the linear and nonlinear static analyses; the fifth includes the design by the LRFD method and its validation; the sixth presents the criteria of seismic performance using the ATC-40 method; the seventh shows the analysis of results; the eighth shows the conclusions and recommendations. From the presented analysis, it is concluded that it was possible to achieve the level of performance desired ensuring continuous ore production, and with this, it can be guaranteed that the structure will have an acceptable behavior for the 3 levels of seismic hazard and that the ore production will not be affected.

Texto completoIndustrial growth in the country is increasing, which generates an increase in the need for new industrial structures. The following thesis has as main objective to represent a guide, through an application example, of analysis and structural design of an industrial building with travelling crane, because Peru doesn´t have exclusive guidelines for this type of structures. A theoretical compilation is presented covering the guidelines for the analysis and structural design of industrial buildings, considering the effects generated by a traveling crane on the structure, and then establishing a clear and concise methodology. It proposes a theoretical project of an industrial building covering an area of 600 m2, whose use will be Warehouse and has a crane bridge of 10 tons of capacity, with the aim of developing the established methodology. The methodology, which includes the analysis and structural design of industrial buildings with Crane bridges, meets the requirements of the regulations: National Building Regulations (RNE), American Institute of Steel Construction (AISC) and the American Concrete Institute (ACI).

Texto completoThe presence of travelling cranes in industrial buildings means an additional effort for the structure of the ship due to the additional loads. Thus, a specific and complete analysis is required, both static and dynamic, to design a structure resistant to the efforts generated by the load coming from the travelling crane. The objective of this article is to elaborate a document that serves as a guide for a correct analysis and design of the beam that supports the travelling crane, known as the rail beam; from the comparison of regulations of some Latin American countries and the North American norms. This analysis includes the set of efforts generated by the operation of a bridge crane. Finally, the proposal or method will be validated with an example of a crane lifting capacity of up to 10 tons.

Texto completoDesarrolla el diseño del drenaje pluvial para la cubierta de la nave industrial del Proyecto Agroforestal de Pijuayo ubicado en el distrito de Caynarachi provincia de Lamas departamento de San Martin, considerando aspectos importantes como las características de la precipitación pluvial, el flujo superficial del agua precipitada y el comportamiento hidráulico en bajadas pluviales. El constante desarrollo económico en Perú, ha permitido que la industria nacional tenga la necesidad imperiosa de tener mayor infraestructura, en muchos casos con el surgimiento de nuevas industrias y en otros en donde requiera de ampliaciones de sus naves industriales del tipo almacén, producción diversa, agro exportación, industria siderúrgica, cementera, minera y demás. Esta infraestructura de tipo nave industrial con cubiertas inclinadas se ven directamente afectadas por las precipitaciones pluviales, por tanto, es necesario e imperioso contar con un drenaje pluvial para poder evacuarlas y así evitar cuantiosos gastos por desbordamiento e inundación. Es común solo considerar como parámetro principal el tamaño o área de una cubierta industrial para estimar un sistema de drenaje pluvial el cual resulta insuficiente para un correcto diseño, ya que las precipitaciones pluviales es otro parámetro necesario de considerar debido a que el Perú cuenta con una diversidad en el comportamiento de las precipitaciones pluviales, por tanto no será lo mismo un sistema de drenaje pluvial para una cubierta industrial que se ubique en la costa que una que se ubique en la sierra o selva.

Texto completo[ES] La formación del arquitecto en España presenta una amplia vertiente técnica, que contempla su capacidad para diseñar y calcular estructuras de edificación. El contexto arquitectónico actual presenta edificios con una complejidad estructural creciente, que requieren necesariamente la utilización de medios informáticos. Los profesionales que buscan un programa de cálculo de estructuras de edificación encuentran serias dificultades en localizar no sólo una relación de los productos comerciales disponibles en el mercado, sino también de estudios rigurosos de sus características, especialmente en aquello relativo a su funcionalidad y su fiabilidad. La legislación nacional actual no regula las prestaciones de este tipo de herramientas informáticas, ni proporciona pautas que permitan comparar sus características y prestaciones o, al menos, que permitan validar el funcionamiento de una de ellas. Paralelamente, la bibliografía internacional disponible es escasa, dispersa y carente de patrones comunes que posibiliten afrontar de manera autónoma tales tareas. Así pues, la presente tesis doctoral asume el reto de elaborar un banco de pruebas que permita a los usuarios conocer e incluso cuantificar la fiabilidad de los programas de cálculo de estructuras de edificación disponibles en el mercado español. El banco de pruebas se configura como un estudio de caso, cuyo planteamiento y metodología se toman del campo de la ingeniería informática, donde sí presenta importantes antecedentes y desarrollo teórico. Su dinámica invita al usuario a evaluar un programa concreto modelizando y calculando la estructura de una nave industrial. Esta tipología, sus características y dimensiones han sido seleccionadas por su representatividad dentro del trabajo diario de los destinatarios de los resultados. Durante el proceso el usuario debe recopilar los resultados para veinte puntos de control en los que se pregunta el valor de reacciones, solicitaciones y movimientos en ciertos puntos e hipótesis de la estructura, así como el valor del dimensionado final de piezas concretas. Los resultados obtenidos serán comparados con aquellos determinados mediante una estricta aplicación de la normativa, utilizando SAP2000 para el análisis y una detallada resolución manual para el dimensionado. Se ha elaborado un manual del usuario del banco de pruebas. Contiene las instrucciones necesarias para el seguimiento del proceso, así como una colección de fichas que permiten recopilar los resultados e incluso determinar una puntuación final de 0 a 10 puntos. Versiones del Generador de Pórticos y del Nuevo Metal 3D de CYPECAD, del Tricalc y del Architrave han sido seleccionadas por su amplia implantación en el mercado estatal actual y han sido sometidas a ensayo. Su estudio ha verificado la validez del banco de pruebas y ha permitido extraer importantes conclusiones. Entre las mismas cabe destacar la notable dispersión de valores en algunos casos. Sorprendentemente, no es consecuencia de una incorrecta computación, sino de las simplificaciones asociadas a la atractiva automatización de tareas que los programas ofrecen a los usuarios y que suelen derivar en sobredimensionados; y también a una insuficiente aplicación de la normativa a considerar, donde la omisión de determinados puntos del articulado puede traducirse en preocupantes infradimensionados. Se pretende que el banco de pruebas elaborado sea una herramienta pública, de acceso y utilización gratuitos. Así pues, los usuarios interesados podrán acceder a la misma con facilidad y compartir sus resultados con la comunidad profesional, empresarial y científica.

El context arquitectònic actual presenta edificis amb una complexitat estructural creixent, que requereixen necessàriament de la utilització de mitjans informàtics. Els professionals que busquen un programa de càlcul d'estructures d'edificació troben serioses dificultats a l'hora de localitzar no només una relació dels productes comercials disponibles al mercat, sinó també d'estudis rigorosos de les seues característiques, especialment pel que fa a la seua funcionalitat i fiabilitat. La legislació nacional actual no regula les prestacions d'aquest tipus d'eines informàtiques, ni proporciona pautes que permetin comparar les seues característiques i prestacions o, almenys, que permetin validar el funcionament d'una d'elles. Paral·lelament, la bibliografia internacional disponible és escassa, dispersa i mancada de patrons comuns que possibiliten afrontar de manera autònoma aquestes tasques. Així doncs, la present tesi doctoral assumeix el repte d'elaborar un banc de proves que permeti els usuaris conèixer i, fins i tot, quantificar la fiabilitat dels programes de càlcul d'estructures d'edificació disponibles al mercat espanyol. El banc de proves es configura com un estudi de cas, amb un plantejament i metodologia presos del camp de l'enginyeria informàtica, on sí que presenta importants antecedents i desenvolupament teòric. La seua dinàmica convida l'usuari a avaluar un programa concret modelitzant i calculant l'estructura d'una nau industrial. Aquesta tipologia, les seues característiques i dimensions han estat seleccionades per la seua representativitat dins del treball diari dels destinataris dels resultats. Durant el procés l'usuari deu recopilar els resultats per a vint punts de controls on es pregunta el valor de reaccions, sol·licitacions i moviments a certs punts i hipòtesis de l'estructura, així com el valor del dimensionat final de certes peces. Els resultats obtinguts seran comparats amb aquells determinats mitjançant una estricta aplicació de la normativa, emprant SAP2000 per l'anàlisi i una detallada resolució manual pel dimensionat. S'ha bastit un manual de l'usuari del banc de proves. Conté les instruccions necessàries pel seguiment del procés, així com una col·lecció de fitxes que permeten recopilar els resultats i, fins i tot, determinar una puntuació final de 0 a 10 punts. Versions del Generador de Pórticos i del Nuevo Metal 3D de CYPECAD, del Tricalc i del Architrave han estat seleccionades per la seua ampla implantació al mercat estatal actual i han estat sotmeses a assaig. El seu estudi ha verificat la validesa del banc de proves i ha permès extraure importants conclusions. Entre aquestes cap destacar la notable dispersió de valors en alguns casos. Sorprenentment, no és conseqüència d'una computació incorrecta, sinó de les simplificacions associades a l'atractiva automatització de tasques que els programes ofereixen als usuaris i que solen derivar en sobredimensionaments; i també a una insuficient aplicació de la normativa a considerar, on l'omissió de determinats punts de l'articulat pot traduir-se en infradimensionats preocupants. Es pretén que el banc de proves elaborat siga una ferramenta pública, d'accés i utilització gratuïts.

Texto completoThe U.S. Navy has been utilizing epoxy polyamide and coal tar epoxy coatings to protect waterfront structures such as piers and wharfs for many years. However these particular coatings have become undesirable for use as their VOC levels exceed the newly instituted guidelines published by the EPA in 1999. Therefore the Navy has begun the process of researching other potential coatings which meet the current federal standards. Some of these coatings include fusion bonded epoxy coatings moisture cured urethane coatings epoxy aliphatic polyurethane with polypropylene fiber coatings and glass flake resin coatings. Some preliminary testing suggests that fusion bonded epoxy and moisture cured urethane coatings provide adequate corrosion resistant properties in the harsh marine environment. However more standardized testing must be instituted for these potential coating systems in order to ensure the Navy makes the most informed decision in the future.

Texto completoENGLISH ABSTRACT: The South African Navy (SAN) intends to reinstate Naval Station Durban (NSD) as a fully operational support base for a new class of Offshore Patrol Vessels (OPV’s) which the SAN intends to purchase. These acquisitions must be seen against the background of strategic and political considerations in general, and in particular threats to South Africa’s maritime security, due to the possibility of the piracy, along particularly the West African coast, reaching our territorial waters. The aim of this thesis is the development of a cost-optimization model, intended to provide optimal locations for the SAN’s support facilities, given the SAN’s operational obligations, present and future. In the first part, a literary review of facility location formulation and strategic management principles is an attempt to lay the foundations for the proposed model. The review of this literature is primarily based on extracts of the comprehensive research of other authors. Consequently, the research problem was contextualized and classified as a hierarchical location-allocation problem. The second part of the thesis aims to describe the SAN’s environment from a maritime security perspective. Within this framework, formulation was identified and modified to develop a theoretical mechanism to solve the research question. The final part will see the application of the developed model to a case study specific to the situation of the SAN. Validation of the inputs and the model itself proceeded in conjunction with the application of the model. The results and the model itself were validated through visual inspection and independent mathematical validation. This thesis comes to the conclusion that the SAN cannot cost-effectively meet its future obligations by splitting its maintenance capability between Naval Base Durban (NBD) and Naval Base Simon’s Town (NBS). Future research may build upon the results of this thesis in order to facilitate a more comprehensive optimization of preventative networks.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse Vloot (SAV) beoog om die vlootstasie in Durban weer op te gradeer na ’n volwaardige vlootbasis vir die beoogde aanskaffing van ’n nuwe klas van patroleringsvaartuie. Die motivering vir die opgradering van Durban kom uit dieper strategiese en politieke behoeftes maar word tans toegeskryf aan plaaslike bedreigings van seerowery en die gevolglike verkryging van nuwe patrollievaartuie om hierdie bedreiging, onder meer, te bekamp. Die doel van hierdie meesters tesis, is om ’n koste optimerings model te vind, of te ontwikkel, wat optimale liggings vir ondersteunings fasilitieite sal lewer, gegewe die toekomstige of huidige verpligtinge van die SAV. Die eerste gedeelte van hierdie tesis bevat ’n literatuuroorsig van fasiliteitsligging-formulering en strategiese bestuursbeginsels. Hierdie literatuuroorsig beoog om die grondslag vir die voorgestelde model te lê. Die oorsig van sodanige literatuur is hoofsaaklik gebaseer op uittreksels uit veelomvattende opsommings deur ander outeurs. Gevolglik is die navorsingsprobleem gekontekstualiseer en geklassifiseer as ’n hiërargiese ligging-toekenningsprobleem. Die tweede deel van die tesis beoog om die omgewing van die SAV vanuit ’n maritieme sekuriteitsperspektief te beskryf. Binne hierdie raamwerk is formulering geïdentifiseer en só gemodifiseer om ’n teoretiese meganisme te ontwikkel om die navorsingsvraag op te los. Die finale deel pas die ontwikkelde model op die spesifieke situasie van die SAV toe. Validasie van die insette sowel as die model self is gedoen in samewerking met die toepassing van die model. Die resultate tesame met die model self is deeglik bekragtig deur visuele inspeksie en onafhanklike wiskundige validasie. Hierdie tesis het tot die gevolgtrekking gekom dat die SAV nie koste-effektief aan sy toekomstige operasionele verpligtinge sal kan voldoen met die verdeling van sy onderhoudsvermoë tussen ’n vlootbasis in Durban en Simonstad nie. Toekomstige navorsing kan op die resultate van hierdie tesis bou ten einde ’n meer omvattende optimalisering van voorkomende instandhoudingsnetwerke te fasiliteer.

Texto completoStudies about management in organizational context are significant for understanding the relationships between business and organizational development. Consequently, management practices must be analyzed in order to better understand how more accurate management influences the organizations performance, improving and making them thereby achieve their goals and desired results. Implementation of Public Policies is one of the ways by which the State seeks to achieve its results. In the study about management, it is crucial to seek the balance of political, organizational, and legal processes and to provide more complex assessment of Science Administration. This research aims to check the current management system used by Arsenal de Marinha do Rio de Janeiro (AMRJ) (the Navy Arsenal of Rio de Janeiro), a Service Provider Military Organization (Organização Militar Prestadora de Serviço-OMPS) that, although considered an industrial OMPS (OMPS-I), has as assignment maintenance of naval assets, support of grassroots, and shipbuilding. Thus, the current obstacles of its management will be checked, as well as their capabilities at the strategic level, and the applicability of management tool that can support the strategic management of that Military Organization. The question is: What aspects in the form of threats and weaknesses do influence the management of AMRJ and what alternatives could be proposed to optimize management and minimize the found dysfunctions? Thus, examination of the current system of management is critical, regarding the execution of its business, in order that AMRJ fulfills its mission with efficiency, effectiveness, and economy. This is an exploratory, descriptive, qualitative, and deductive research, using the case study method, field research, and literature. Despite many limitations and threats found, strengths and opportunities are significant. The survey sought to maximize the overall result of the Military Organization, seeking to adjust the set of organizational elements that compose the organizational structure of AMRJ, in order to achieve synergy of isolated action, but under the same strategic direction to allow a range of effectiveness and higher efficiency for this important Brazilian Navy Military Organization.

Para a escolha do melhor extrator de caracterÃsticas, foram comparados os seus desempenhos de classificaÃÃo em termos de taxa de acerto e de tempo de extraÃÃo, atravÃs do classificador k-Vizinhos mais PrÃximos utilizando distÃncia euclidiana. O extrator de caracterÃsticas baseado nos momentos de Zernike obteve as melhores taxas de acerto, 98.00%, e tempo relativamente baixo de extraÃÃo de caracterÃsticas, 0.3910 segundos. Os dados gerados a partir deste, foram apresentados a diferentes heurÃsticas de classificaÃÃo. Dentre os classificadores testados, o classificador k-Vizinhos mais PrÃximos, obteve a melhor taxa mÃdia de acerto, 98.00% e, tempo mÃdio de classificaÃÃo relativamente baixo, 0.0040 segundos, tornando-se o classificador mais adequado para a aplicaÃÃo deste estudo.
In this work, the problem of recognition of objects using images extracted from a 3D industrial sensor is discussed. We focus in 9 feature extractors (where seven are based on invariant moments -Hu, Zernike, Legendre, Fourier-Mellin, Tchebichef, BesselâFourier and Gaussian-Hermite-, another is based on the Hough transform and the last one on independent component analysis), and 4 classifiers (Naive Bayes, k-Nearest Neighbor, Support Vector machines and Artificial Neural Network-Multi-Layer Perceptron). To choose the best feature extractor, their performance was compared in terms of classification accuracy rate and extraction time by the k-nearest neighbors classifier using euclidean distance. The feature extractor based on Zernike moments, got the best hit rates, 98.00 %, and relatively low time feature extraction, 0.3910 seconds. The data generated from this, were presented to different heuristic classification. Among the tested classifiers, the k-nearest neighbors classifier achieved the highest average hit rate, 98.00%, and average time of relatively low rank, 0.0040 seconds, thus making it the most suitable classifier for the implementation of this study.

Texto completoInnan företag ska penetrera en marknad är det viktigt att de har tillräckligt med information om vilka möjligheter och hot marknaden står inför samt vilka behov företagen på marknaden har. Denna magisteruppsats syftar till att utreda framtids-utsikterna inom branscherna solenergi och vågkraft samt identifiera OEM-företagens behov inom dessa branscher. Det verktyg vi har använt för att utreda branschernas framtidsutsikter är delar av SWOT-modellen, där fokus har lagts på externa faktorer som påverkar en marknad. För att identifiera OEM-företagens behov har vi använt teorier kring OEM-marknaden och OEM-företags köpkriterier samt ABB:s egen erfarenhet och kunskap om denna marknad.
För att ge en informationsrik och heltäckande bild har vi genomfört intervjuer med Energimyndigheten och OEM-företag inom branscherna solenergi och vågkraft, då de besitter kunskap om vilka möjligheter och hot branscherna står inför. Vidare har intervjuer genomförts med OEM-företagen för att få information om vilka behov företag inom dessa branscher har.
Med anledning av ett ökat intresse och medvetenhet kring klimat-förändringarna har politiska målsättningar satts upp och åtgärder vidtagits för att hejda klimat-förändringarna och öka användningen av förnyelsebara energikällor. Det innebär att gynnsamma förutsättningar för förnyelsebara energikällor har skapats.
Studien visar att den avgörande faktorn för fortsatt tillväxt på solenergimarknaden är olika former av ekonomiska stödsystem. Eftersom investeringsstödet i Sverige kommer att förlängas och även utökas till att omfatta privatpersoner samt att flertalet länder har ekonomiska bidrag för att stödja marknaden ser framtidsutsikten för solenergi-branschen positiv ut. Ur ett långsiktigt perspektiv krävs det dock politiskt och juridiskt stöd både nationellt och internationellt under en längre period till dess att marknaden har utvecklats till att kunna stå på egna ben. Därtill behöver tekniken och tillverknings-processerna förbättras ytterligare för att företagen ska kunna erbjuda en prisvärd och konkurrenskraftig produkt. Studien visar att på grund av att marknaden befinner sig i ett tidigt skede har OEM-företagen de primära behoven kvalitet, pris och leverans-säkerhet. När marknaden mognat kommer sannolikt andra köpkriterier som leverantörens varumärke bli av större vikt.
Framtidsutsikten för branschen vågkraft är osäker eftersom vågkraftskoncept inte har etablerats kommersiellt ännu samt att det inte finns fullskaliga vågkraftskoncept som varit i drift över en längre tid. Det betyder att tekniken idag inte är tillräckligt beprövad och därmed inte kan ses som tillförlitlig. OEM-företagens främsta behov är kvalitets-komponenter, kringtjänster och hög leveranssäkerhet. Det bör även tas hänsyn till att denna marknad är i utvecklingsstadiet och därmed är i behov av leverantörer som tillhandahåller prisvärda och anpassade komponenter som OEM-företagen i dagsläget inte har tillgång till.
It is important, when penetrating a market, that companies have sufficient information about the opportunities and the threats on a market as well as the relevant needs for the purchasing companies in the market. The purpose of this master thesis is to investigate the prospects of solar and wave energy systems and identify the needs of the OEM companies within these businesses. To investigate the future market opportunities we have applied parts of the theoretical model SWOT, focusing on external elements that impact the market. The theoretical framework is based upon theories about the OEM market and used to identify the needs of the OEM companies. ABB has also contributed with their experience and knowledge of the OEM market.
We have interviewed the Swedish Energy Agency and OEM companies in the solar and wave energy business, since they have knowledge about the opportunities and threats of the markets. The information aim to give a complete and comprehensive picture of market opportunities and threats. We have also interviewed the OEM companies to receive information about their specific needs.
Because the interest in and awareness of environmental change has increased, favorable political systems have been created for a continuing positive market development in renewable energy sources.
For a continuing market growth of the solar energy market, the study demonstrates the importance of financial funding. The economical funding in Sweden will be extended and involve private persons which means that the future of the market is positive. Several countries also support the market with financial funding. Due to the fact that the technology and production processes needs continuing improvement before it can manage on its own, it is important that the market get extended national and international political and legal support. The study demonstrates that OEM companies due to the fact that the market is in an early state the market have the primary needs quality, price and on-time-delivery. When the market reaches a mature level other purchasing criterions, such as the brand of the supplier, will probably be of greater importance.
Since the wave energy concepts not yet have been commercially established and that full scale wave energy concepts have been installed over sufficient time the prospects of wave energy is unsure. That means that the technology still not properly has been tested and can be seen as not yet reliable. The importance of the OEM companies is quality components, service and support and high on-time-delivery. It should be taken in consideration that the market is under development and therefore is in need of suppliers that provide customized components to the right price, which the OEM companies do not have access to today.

Texto completoThe purpose of this study is to find the critical design area in industrial buildings that combine the premise of different free heights with the location of different load capacities of an overhead crane. A total of nine symmetrical models were proposed in plan with a gabled portico arrangement. The structural system includes frames at the moment and braced frames. The span of the overhead crane longitudinally and transversely determined between 10 to 90 locations where the overhead crane load is concentrated for the analysis. The loads considered for the analysis and design were those produced by dead load, live load, wind and earthquake. For the design of the elements of the industrial buildings, Standard E.090 of the National Building Regulations has been considered and as a complement the following standards have been used: ASCE and AISC. The design of the structural elements was based on the LRFD method. The result of the investigation found a critical design zone on the left and right margins of each model. The values of both margins corresponding to the load capacity of the overhead crane are equal in each of their symmetrical positions. It was found that in the critical zone there is a single location that generates the maximum performances in the elements of the industrial buildings. The cost ratios of the profiles of the industrial buildings were determined; which, vary between 51 and 190 dollars per square meter.

In the last decades, the transformation industry has provided the introduction of increasingly faster and more energy efficient products for residential, commercial and industrial use, however these loads due to their non-linearity have contributed significantly to the increase of distortion levels harmonic of voltage as a result of the current according to the Power Quality indicators of the Brazilian electricity distribution system. The constant increase in the levels of distortions, especially at the point of common coupling, has generated in the current day a lot of concern in the concessionaires and in the consumers of electric power, due to the problems that cause like losses of the quality of electric power in the supply and in the installations of the consumers and this has provided several studies on the subject. In order to contribute to the subject, this thesis proposes a procedure based on the Knowledge Discovery in Database - KDD process to identify the impact loads of harmonic distortions of voltage at the common coupling point. The proposed methodology uses computational intelligence and data mining techniques to analyze the data collected by energy quality meters installed in the main loads and the common coupling point of the consumer and consequently establish the correlation between the harmonic currents of the nonlinear loads with the harmonic distortion at the common coupling point. The proposed process consists in analyzing the loads and the layout of the location where the methodology will be applied, in the choice and installation of the QEE meters and in the application of the complete KDD process, including the procedures for collection, selection, cleaning, integration, transformation and reduction, mining, interpretation, and evaluation of data. In order to contribute, the data mining techniques of Decision Tree and Naïve Bayes were applied and several algorithms were tested for the algorithm with the most significant results for this type of analysis as presented in the results. The results obtained evidenced that the KDD process has applicability in the analysis of the Voltage Total Harmonic Distortion at the Point of Common Coupling and leaves as contribution the complete description of each step of this process, and for this it was compared with different indices of data balancing, training and test and different scenarios in different shifts of analysis and presented good performance allowing their application in other types of consumers and energy distribution companies. It also shows, in the chosen application and using different scenarios, that the most impacting load was the seventh current harmonic of the air conditioning units for the collected data set.
Nas últimas décadas, a indústria de transformação, tem proporcionado a introdução de produtos cada vez mais rápidos e energeticamente mais eficientes para utilização residencial, comercial e industrial, no entanto essas cargas devido à sua não linearidade têm contribuído significativamente para o aumento dos níveis de distorção harmônica de tensão em decorrência da corrente conforme indicadores de Qualidade de Energia Elétrica do sistema brasileiro de distribuição de energia elétrico. O constante aumento dos níveis das distorções, principalmente no ponto de acoplamento comum, tem gerado nos dias atuais muita preocupação nas concessionárias e nos consumidores de energia elétrica, devido aos problemas que causam como perdas da qualidade de energia elétrica no fornecimento e nas instalações dos consumidores e isso têm proporcionado diversos estudos sobre o assunto. Com o intuito de contribuir com o assunto, a presente tese propõe um procedimento com base no processo Knowledge Discovery in Database - KDD para identificação das cargas impactantes das distorções harmônicas de tensão no ponto de acoplamento comum. A metodologia proposta utiliza técnicas de Inteligência computacional e mineração de dados para análise dos dados coletados por medidores de qualidade de energia instalados nas cargas principais e no ponto de acoplamento comum do consumidor e consequentemente estabelecer a correlação entre as correntes harmônicas das cargas não lineares com a distorção harmônica no ponto de acoplamento comum. O processo proposto consiste na análise das cargas e do layout do local onde a metodologia será aplicada, na escolha e na instalação dos medidores de QEE e na aplicação do processo KDD completo, incluindo os procedimentos de coleta, seleção, limpeza, integração, transformação e redução, mineração, interpretação, e avaliação dos dados. Com o propósito de contribuição foram aplicadas as técnicas de mineração de dados Árvore de Decisão e Naïve Bayes e foram testados diversos algoritmos em busca do algoritmo com resultados mais significativos para esse tipo de análise conforme apresentado nos resultados. Os resultados obtidos evidenciaram que o processo KDD possui aplicabilidade na análise da Distorção Harmônica Total de Tensão no Ponto de Acoplamento Comum e deixa como contribuição a descrição completa de cada etapa desse processo, e para isso foram comparados com diferentes índices de balanceamento de dados, treinamento e teste e diferentes cenários em diferentes turnos de análise e apresentaram bom desempenho possibilitando sua aplicação em outros tipos de consumidores e empresas de distribuição de energia. Evidencia também, na aplicação escolhida e utilizando diferentes cenários, que a carga mais impactante foi a sétima harmônica de corrente das centrais de ar condicionado para o conjunto de dados coletados.

Texto completoEn el periodo 2015 2016, a raíz de un convenio del Ministerio de la Vivienda y Urbanismo MINVU y el Instituto de la Construcción IC, se realizó una revisión de la norma NCh 2369. Of. 2003 Diseño sísmico de estructuras e instalaciones industriales. Los textos finales propuestos aún se deben someter al proceso de validación del Instituto Nacional de Normalización INN. La siguiente memoria aborda las modificaciones en el Capítulo 9: Disposiciones especiales para estructuras de hormigón. El objetivo del Trabajo de Título es verificar con ejemplos y una comparación teórica, la aplicación de los nuevos requisitos en estructuras industriales típicas construidas con prefabricados de hormigón, como se resuelven los problemas observados durante el sismo del 27 F, y en algunos casos si los límites para las nuevas deformaciones son posibles de cumplir en la práctica. Se incluirán en el estudio las naves estructuradas con sistemas de: Pilares en voladizo y Pilares con vigas que forman marcos de momento. También se incluirán los sistemas de arriostramiento y los paneles de cerramiento exterior y de divisiones interiores. Con las modificaciones propuestas los resultados más importantes obtenidos consisten en que las estructuras tipo pilar en voladizo con estructura de techo de acero (estructuras mixtas) y sólo algunas estructuras livianas de hormigón prefabricado, podrán construirse en suelo tipo II y III. Mientras que, en el caso de estructuras tipo marco rígido fundadas sobre suelos tipo II y III, se obtiene un aumento de la deformación considerable de casi el doble. La conclusión principal es que las estructuras tipo marco rígido serán preferidas en la práctica por sobre las de tipo pilar en voladizo. Además, se propone un amortiguamiento unificado para ambos tipos de estructuras de 3% y un nuevo límite sobre la cantidad de momento traspasado en la cabeza de los pilares para poder diferenciar cuantitativamente las estructuras tipo marco rígido de las pilar en voladizo. Se deja planteado que es necesario realizar un nuevo análisis en los límites de deformación ahora que las deformaciones calculadas son más cercanas a las deformaciones reales de las estructuras.

Texto completoFrom 1871 to 1961, the French Navy underwent changes of all kinds which were at the origin of the emergence of a new system of production of naval weapons. This transformation was caused by a continuous need to strengthen the fleet, by successive and rapid technological innovations, and by the triumph of industrial capitalism. From the 3rd to the 5th Republic, the construction of naval weapons therefore passed from industrial practices centered on the traditional arsenals and factories of the Navy, to the command of warships entrusted to private industry

Texto completoThis thesis aims to understand the obstacles to the purchase of generic drugs in patients-consumers. More specifically, it aims, through a qualitative and a quantitative study, to improve the efficiency of communication of health actors to reduce the perceived risk in buying generics. More precisely, it intends to examine the variables that explain the patients-consumers attitudes towards the substitution, to understand the mechanisms involved in this process and to highlight the most likely variables that explain the intention of purchasing a generic (vs brand name) drug. Thus, we aimed to explore the factors that explain the perception and reduction of risks towards the generic drugs by conducting individual semi-structured interviews with 24 patients-consumers. The results of the quantitative study of 303 individuals point out that (1) the perceived risk towards the substitution and the attitude towards generic drugs mediate the relationship between the perceived risk towards generic drugs and attitude towards substitution, (2) the trust in the information source (pharmacist and physician) moderates the relationship between the attitude towards substitution and the intention of purchasing a generic (vs brand name) drug and (3) the interaction effect between the brand equity of generic drug : low (vs strong ), the chronicity of disease : non chronic (vs chronic) and the repayment rate : 65% (vs 100%) on the intention purchase generic (vs brand name) drug is validated. Theoretically, the research sheds light on the literature on the perceived risk in health, including mobilizing a concept from the medicine "Nocebo effect". The managerial implications are manifold for generic pharmaceutical industry as well as for pharmacists, physicians, and, finally government makers of communications policies for generic drugs

Texto completoThe study of the contribution agreement dynamizes the classic contractual scheme of intellectual property exploitation based on the pair licence- assignment and provides a detailed analysis of the mechanism of the contribution to a company. Despite a certain similarity to conventional intellectual property exploitation contracts, the contribution agreement is an original contract. This originality is reflected legally by a hybrid nature as well as a heterogeneous applicable system. Regarding intellectual property, the contribution agreement is a specific act of exploitation of intellectual goods. Regarding company law, it is the agreement which enables delivery of the intellectual goods to the company and constitutes an essential element of the company¿s constitution. This duality directly affects the conditions of contract formation as well as its effects. Although the applicable system is based on the traditional contracts of exploitation of intellectual goods, in particular the articles of civil law relating the sale and lease of tangible assets, there is no further similarity. On the one hand, the formation of the contribution agreement follows numerous constraints posed by company law and competition law. On the other hand, the understanding of the parties¿ rights and obligations differs. The relationship between the company and the contributor is imbued with the intuitu personae attached to intellectual goods as well as the affectio societatis resulting from the nature of the partnership agreement. Given the lack of regulation adapted to the specificity of intellectual property contribution agreements, the emphasis has been put on contract drafting. Such a legal deficiency must be supplemented by contractual freedom without breaking the principles of public policy

Esta parceria resultou numa mais-valia qualitativa tanto na análise e dimensionamento estrutural como no aprofundamento do conhecimento dos métodos e instrumentos de fabrico e suas particularidades, através da orientação providenciada em várias visitas às instalações da Fametal. Devido à impraticabilidade de analisar as inúmeras soluções estruturais possíveis, limitou-se o campo de aplicação do estudo aqui realizado a estruturas constituídas por pórticos simples, estabilizados por contraventamentos transversais. Esta decisão fundamenta-se no facto desta solução estrutural ser reconhecida como uma das mais utilizadas e eficazes, no contexto dos edifícios industriais em estrutura metálica. Primeiramente foram abordadas as várias fases de projecto e de fabrico e a sua importância na qualidade global do projecto, e em seguida realizada uma análise qualitativa às soluções mais comummente adoptadas neste tipo de edifícios. Apresentaram-se os principais parâmetros que influenciam o dimensionamento deste tipo de estruturas: o vão a vencer pelos pórticos; o afastamento entre estes; a altura do edifício; o tipo de perfil adoptado, as dimensões dos esquadros de ligação, e a sua gama de variação, resultando na análise e dimensionamento de mais de 600 estruturas, tendo em conta os princípios constantes nos Eurocódigos estruturais. Os resultados demonstraram que as colunas em perfil IPE e as travessas em perfil HEA se revelam mais económicas. Verificou-se que o aumento da altura provoca um incremento exponencial do peso da estrutura e que maiores afastamentos entre pórticos se traduzem numa maior economia global. O esquadro de ligação revela-se pouco influente, em relação aos demais parâmetros analisados. O aumento do vão provoca um incremento exponencial do peso da estrutura, estando esta tendência sujeita a variações conforme a altura do edifício. Todo o processo de modelação e dimensionamento foi realizado com auxílio do software de cálculo Robot Structural Analysis 2013.
This paper’s objective is to determine the most effective and economical geometry of steel structures for industrial buildings. The work developed in order to present this study had the support from the Civil Engineering Department of the University of Coimbra and from the company Fametal – Fábrica Portuguesa de Estruturas Metálicas, merging synergy and knowledge. This partnership provided a quality boost of the structural analysis and design, as well as a deeper knowledge of manufacturing procedures, through orientation in several visits to Fametal. Due to the impossibility of covering the vast structural solutions avaliable, the study’s field of application was limited to structures constituted by simple frames with solid section beams, stabilized by cross bracings. This decision was based in the recognized efficiency and vastly use of that solution. Firstly, the several phases of a project and manufacturing were described, as well as their importance in the global quality of the project, followed by a qualitative analysis of the most common solutions adopted in this type of buildings. The study and its results were demonstrated, product of the systematic variation of the key parameters taken into account in a project: floor plan; height; frame spacing; cross-section and bracket’s geometry. The structural design for each variation was done according to European regulations (Eurocode), wich enabled the study of the relations between their variation and influence on the final design and weight of the structure. As a result of the considered parameters and its variation more than 600 structures were calculated. Frames constituted by columns with IPE section and beams with HEA section were the most economical structures. An exponential growth was observed in structural weight as a result of height increasing and tighter frame spacing. The influence of the bracket’s geometry was not significant, when compared to the other variables. Longer spans were associated to an exponential increase of weight, being this tendency subject to variations mainly due to the height of the building. All the modeling process and structural analysis and design were performed with the software Robot Structural Analysis 2013.
