Повний текст джерелаGli iniettori di neutri sono e saranno il principale sistema di riscaldamento nelle macchine da fusione. La modellazione numerica gioca un ruolo fondamentale nel predirne le prestazioni ed ottimizare il suo funzionamento, ed un buon design nella fisica e ingegneria può essere raggiunto solo tramite un apporoccio integrato tra i due. Nei tre anni trascorsi, ho svolto la mia attività di ricerca presso il Consorzio RFX, dovesarà installato e testato il più grande iniettore di neutri al mondo, ed il suo design è in corso. Questa tesi di dottorato ha affrontato aspetti critici per il design e le operazioni di questa tipologia di iniettori. Poiché le dinamiche di accelerazione e trasporto del fascio di particelle sono dominate dalla presenza di gas residuo, ho sviluppato un codice robusto ed affidabile per simulare la sua distribuzione e flusso nei sistemi di alto vuoto; questo argomento è strettamente legato alle caratteristiche ed il design della cella di gas dove il fascio deve venire neutralizzato prima di raggiungere il plasma da fusione, di cui ho sviluppato il final design ed ho eseguito le verifiche termomeccaniche, che presentano tutte le difficoltà di componenti affacciati ad un fascio di particelle ad alta energia. Altri aspetti hanno riguardato lo studio di componenti e diagnostiche del fascio. Vengono trattati lo sviluppo e l’applicazione di metodi e modelli, e la loro eventuale validazione sperimentale; i risultati sono valutati nella prospettiva di un uso pratico nella ingegneria degli iniettori di neutri.

Повний текст джерелаThe main objective of this research is to determine which front-of-pack label system has the greatest communication effectiveness according to the perception of consumers of Lima Metropolitan Area. The hypothesis is that the system that complies with the principles of information design is more effective in the perception of consumers in Lima Metropolitan Area. These principles are functional, aesthetic and cognitive. The design established for this research is mixed since it focused on obtaining qualitative and quantitative data. On the one hand, nine labels with greater global relevance were analyzed. On the other hand, key informant interviews to experts in information design and consumers in Lima Metropolitan Area were carried out. Finally, a digital survey was developed for the same consumers. The main findings are that most consumers link the term front-of-pack label system to the warning octagon label. They also consider that this tool manages to influence their perception and purchase decision. As for the perception of the labels, the traffic light label, the warning octagon label and NutriScore are the best considered by users of Metropolitan Lima Area. Conclusively, the traffic light label has the greatest communication efficiency. The characteristics that reinforce this are the application of colors in a consistent manner, text, and neutrality. Also, it is concluded that the labeling manages to influence the perception of consumers. Finally, the consumers have the need to compare products through labelling.

Повний текст джерелаTraffic congestion is the second largest of the limeans problem, this is due to that the current transport system has some shortcomings. However, there are vehicular systems who have had more success, as it is the case of the Metropolitan system of transportation of Lima (Metropolitan). However, this also presents some deficits in its environmental design that not allows that users can manage is correctly in its facilities. Therefore, so the objective of the present study is to identify the main problems encountered in the system Metropolitan Transportation of Lima (Metropolitan) in order to create a proposal for a solution based on tools that provides design Environmental to thus be able to check if it is a good implementation of environmental graphic design, making use of its elements accompanied by the use of branding, Visual codes, and a method of project focused on design in the Metropolitan system of Transportation of Lima will allow that their user experience is improved. This study was an Experimental investigation level exploratory and qualitative approach, since the objective was to find the causes by which the users unable to connect completely with the metropolitan facilities. The proposal was the implementation of a system of environmental design that goes along with a new identity. The result of the test was mostly favourable so we can say that the hypothesis presented was validated in this study.

Повний текст джерела‘Directed Freedom: Formal Analysis of the Videogame as a System, its Structure and its Avatarness’ This dissertation belongs in the field of Game Studies (and, specifically, Game Design Theory). Its main object is the freedom of action within the videogame system, understood as “directed freedom”. This freedom arises from the combination of the “avatarness” (representation of the player) and the flexibility of the game structure (its possibilities and the order engraved in its design). This dissertation develops a theoretical and methodological model for the analysis of these two aspects, describing the authorship of the play process as something shared by the designer and the player. Between them there is a playable pact that delimits the offered freedom. Four cases, corresponding to four combinations, are studied: closed representation and structure in ‘Metal Gear Solid 3: Snake Eater’, closed representation and open structure in ‘Catherine’, open representation and structure in ‘Mass Effect 3’ and open representation and closed structure in ‘3D Dot Game Heroes’

Повний текст джерелаThe development of tourism has been recently characterized by the importance of the natural environment and of the historical and cultural resources. By now, this idea of a common heritage should be shared and permeated by the concepts of sustainability and quality of life. Unfortunately the economic factor is also involved, leading many contradictions and the environment, the landscape, the identity and the cultural traditions, have often suffered the weight of tourism development, rather than grow up with it. The difficulty of coordination between actions of protection and activities of promotion, especially in areas such as the Marche Region, characterized by depopulation, faces another very important aspect: the active involvement of local communities at every levels , seen as a solution to increase the attractiveness of the territory. The research, therefore, is a contribution to address this context, by proposing a methodological reading, interpretation and planning of the territory, considering the development of sustainable tourism and community participation as fundamental elements. This work starts from two basic premises. The first concerns the project of the landscape that, over the years, due to important documents, such as the European Landscape Convention (ELC, Florence, 2000), has started to have a strategic role in the transformation of the territory. The landscape is an essential element to define the cultural identity and the diversity of local and regional authorities. It had to adapt increasingly, through research of new tools for analysis and action, new scales of work, new approaches to the needs generated to the emergency of the concepts of sustainability and development, and by the growing demand for involvement by the community local decision-making. The second consideration is related instead to the importance of the territory as a "tourist element" and the need to set the conditions for the development and the growth of this sector in a sustainable way. The European Charter for Sustainable Tourism (ETSC, Europarc Federation, 2000) is a methodological tool useful for protected areas, which promotes the practical application of the concept of tourism and sustainable use of territory. The challenge is to transform the ETSC into the tourist interest to the area in economic development opportunities and, simultaneously, to link these opportunities with the protection of this natural, historical, cultural, social and symbolic heritage, value that defines its identity. In particular, the research refers to the phases of the "Analysis" and "Diagnosis" in preparation for the definition of "Strategy and Program of Action” and consist in the application of this method to the Regional Natural Park “Gola della Rossa e Frasassi”. The proposed methodology is divided in analysis, diagnosis and prognosis, and represents an important strategic tool for knowledge of the area and for a direct communication with the population. It also allows the consolidation of local identity that is strengthened by the conception and implementation of common projects in all geographical and touristic areas, by promoting a unified vision of the territory no longer considered as the sum of heterogeneous territories, but as a place of synthesis and fitting, with its own character and identity.

Повний текст джерела[CAT] El desenrotllament tecnològic ha canviat la forma en què els usuaris es relacionen amb els productes deixant de ser tresorers passius de funcions per a interactuar amb sistemes cada vegada més complexos. El creixent avanç de les noves tecnologies aplicades en el mercat del retail, permet que la venda de productes s'efectue sense el contacte personal entre venedor i comprador, sent el registre i pagament efectuats en equips electrònics d'autoservici cridats de self-checkout. La utilització a gran escala d'estos equips obliga el consumidor a participar en el procés d'atenció realitzant tots els passos de la compra, des de pesar els productes, registrar-los i efectuar el pagament. No obstant això, esta participació no sempre satisfà l'usuari, podent causar experiències negatives relacionades amb falles d'interacció. Una vegada que la introducció de les tecnologies autoservicis depén de la capacitat de l'usuari per a comprendre el sistema i adoptar l'ús del servici, és important identificar els requisits de disseny que permeten una bona interacció. No obstant això, els estudis sobre el disseny de la interacció dels equips electrònics, especialment dels self- checkouts, són escassos en l'àrea del disseny, així com els estudis que se centren en l'adopció del sistema pels usuaris. El present estudi pretén verificar quina és la necessitat de millorar la interacció a través de la identificació d'atributs i factors situacionals d'interactivitat, així com l'impacte en la satisfacció i intenció de l'usuari de tornar a usar el sistema. Les dades sobre l'avaluació realitzada pels usuaris del sistema d'autopagament, es van arreplegar a Portugal a través d'un qüestionari realitzat en persona. L'estudi analitza el grau de satisfacció quant a la qualitat i interacció amb el sistema, el grau de motivació per a la seua adopció, així com el perfil dels usuaris i la tendència a adoptar en el futur noves tecnologies de registre i pagament de productes basats en una mostra de 400 consumidors. L'anàlisi de les dades de la mostra revela que la majoria dels usuaris tenen formació escolar mitja / alta i utilitzen amb molta regularitat noves tecnologies. A més, presenten un fàcil aprenentatge i un domini elevat del sistema. El motiu per a utilitzar el self-checkout es deu principalment a les cues d'espera en les caixes amb operador i al xicotet volum de productes. En general, l'anàlisi revela un alt grau de satisfacció amb el servici i amb la qualitat, no obstant això, en termes comparatius, les caixes d'autoservici no es consideren millors que les caixes tradicionals. L'avaluació de la interacció amb el self-checkout va ser classificada segons vint-i-sis atributs del sistema. L'anàlisi identifica quatre grups amb característiques semblants, de les quals dos presenten una avaluació baixa. L'anul·lació d'articles registrats, el registre d'articles sense codi de barres, el registre manual, l'àrea d'ensacat, els missatges d'error, el sensor de pes i la sol·licitud de factura són set atributs crítics del sistema. Es va verificar que el grau de concordança sobre la introducció en el self-checkout recau sobre les tecnologies RFID (identificació per radiofreqüència). Finalment, s'assenyalen algunes bones pràctiques d'aproximació a l'arreplega d'informació per a projecte, sobretot a les dades que es referixen a l'usuari - com observar, com investigar i quines proposades pràctiques disposar en el període proyectual. Els resultats indiquen que l'anàlisi de la interacció orientada al servici self- checkout pot ser determinant per a la satisfacció de l'experiència de l'usuari. Les implicacions derivades de les constatacions empíriques es discutixen junt amb orientacions per a futures investigacions.
[EN] Technological development has changed the way users relate to products from being passive recipients of functions to interacting with increasingly complex systems. The increasing advance of the new technologies applied in the retail market allows the sale of products to be made without the personal contact between seller and buyer, and the registration and payment are made in self-service electronic equipment called self-checkout. The large-scale use of these types of equipment obliges the consumer to participate in the service process by performing all the steps of the purchase, from weighing the products, registering them and making the payment. However, this participation does not always satisfy the user, and may cause negative experiences related to interaction failures. Since the introduction of self-service technologies depends on the user's ability to understand the system and adopt the use of the service, it is important to identify the design requirements that allow for good interaction. However, studies on the design of interaction of electronic equipment, namely self-checkouts, are scarce in the area of Design, as well as studies that focus on users' adoption of the system. The present study aims to verify the need to improve interaction through the identification of attributes and situational factors of interactivity, as well as the impact on user satisfaction and intention to reuse the system. The data related to the evaluation made by the users of the self-checkout system were collected in Portugal through a questionnaire carried out in person. The study examines the degree of satisfaction with the quality and interaction with the system, the degree of motivation for its adoption, as well as the profile of users and the tendency to adopt new technologies for registration and payment of products based on a sample of 400 consumers. Analysis of the sample data shows that most users have medium to high school education and regularly use new technologies. In addition, they present easy learning and a good understanding of the system. The reason for using self-checkout is mainly due to not having to wait in queues at the manned checkout and the small quantity of products. In general, the analysis reveals a high degree of satisfaction with the service and quality, however, in comparison, self-checkouts are not considered better than traditional manned checkouts. The evaluation of the interaction with the self-checkout was classified according to twenty-six attributes of the system. The analysis identifies four groups with similar characteristics, two of which present low scores. Withdrawal of registered items, registration of articles without bar code, manual registration, bagging area, error messages, weight sensor and invoice request are seven critical attributes of the system. It was also verified that the degree of agreement on the introduction in the self-checkout relies on RFID (radio frequency identification) technologies. Finally, some good practices for approaching the collection of information for the project are pointed out, especially the data that concerns the user - how to observe, how to inquire and what practical proposals to have in the design period. The results indicate that the analysis of the interaction oriented towards the self-checkout service can be a determining factor in user experience satisfaction. The implications of empirical findings are discussed together with guidelines for future research.

Повний текст джерелаThe construction industry sector in Peru, unlike other industries, is characterized by high variability due to the little industrialization it has, and the growth of this sector is directly associated with the economic growth of the country, since which is a source of employment generation. One of the favorable aspects of this sector is shown when public or private investment increases, as it reacts almost immediately. However, the construction sector has always been associated with poor performance. Construction has always been seen as a poorly productive and dubious quality sector given the low specialization of workers in the sector; Currently this perspective of the construction worker is changing because those workers who want to be part of the sector need to be in the RETCC (Civil Construction Workers Registry); which seeks the formalization of the worker, training, specialization and exercise union positions within the sector. In addition, the sector has been classified as a high-risk activity due to the numerous accidents that from time to time come to public light and are caused by the unsafe conditions in which the workers work, creating uncertainty about the working conditions in which workers perform. The principal characteristic of the sector is the pressure of work that all workers must endure, including the construction team, which means that appropriate solutions to the problems that arise on the ground are not always given, mainly because they live day to day. In addition to the aforementioned problems, poor or little planning of works generates low productivity, for example, it is very common in works that the materials or equipment necessary for the execution of an activity do not arrive in a timely manner. , a completely predictable situation if there is adequate planning. The purpose of this research is to demonstrate that construction planning using a tool such as Lean Construction (a tool that comes from the Lean Production methodology of the Toyota automotive industry of the 1950s, which has been adapted to the automotive industry). construction), can help increase productivity and therefore reduce work execution times, production costs, as well as improve quality and safety in the work execution process. It is therefore the final objective of this work to demonstrate how applying “Lean Construction” tools such as the “Last Planner” to a specific project in this case to the structural part of the construction project of the Cayetano Heredia medical clinic extension can be achieved better planning of the work that in turn will achieve compliance or reduction of the work deadline, as well as improvement in production costs (savings in materials by reducing waste, saving in labor by having planned logistics needs and processes) , the latter (economic results) demonstrated by measuring the improvement of the financial indicators (Van and Tir) applied both to the traditional programming and to the programming resulting from the use of the “Last Planner”.

Повний текст джерелаThe research is aimed at presenting a new integrated approach to aid operators and designers to manage the design process as a whole in refurbishment interventions of recent existing building stock, through the use of innovative technological envelope solutions. The study requires the acquisition of a selection of typological and constructive envelope solutions, as a starting point for the development of design solutions to be used for architectural renovation of schools built after the Second World War, in reinforced concrete and mostly prefabricated. The project identifies sustainable construction processes for the design of “active”, adaptive, efficient and dry assembled envelope components, in accordance with the performance requirements prescribed by current regulations. The purpose of the research is to manage the whole design process with the support of geometrical survey, connected to parametric programming software for modelling surfaces which can be adapted to the morphology of existing buildings. These computerized CAD-CAM tools are connected to CNC machines for “customized” industrialized production. To illustrate this innovative approach, two envelope solutions are proposed, according to the research paradigms and the principles of sustainability, meant as modularity, speed of setup, reversibility, recycling and reuse of materials with low environmental impact. In particular, the innovative solutions have in common the application of a technique based on the assembly of prefabricated components, the adoption of hexagonal patterns for the tessellation of the new surface of the façade, and the use of the same plastic and inorganic, recycled and sustainable, thermal insulation material (AAM-Alkali Activated Materials).The design solutions proposed are developed at the two sites involved in the joint

Повний текст джерела[CA] Els sistemes d'enginyeria o físics solen ser incerts. La seua incertesa es manifesta quan el sistema mostra comportaments que són relativament diferents als que el seu model prediu; sent principalment causada per: errors de modelatge; dinàmiques desconegudes; canvis en les propietats del sistema; interaccions aleatòries amb altres sistemes; o canvis en les condicions d'operació. Durant els últims 40 anys, s'ha demostrat reiteradament que les incerteses dels sistemes poden tindre efectes molt negatius sobre el comportament d'un controlador si aquestes no es consideren adequadament les seues formulacions matemàtiques. Per aquesta raó, una part important de la investigació actual està centrada en aquest tema; buscant les formes mes adequades per a representar matemàticament les incerteses dels sistemes, així com buscant noves tècniques matemàtiques que permeten fer ús d'aquesta representació de la incertesa amb l'objectiu de dissenyar algorismes de control robustos. En aquesta tesi es presenten noves aportacions en aquesta línia. Concretament, es desenvolupen noves metodologies per a dissenyar controladors (DOBCs) i predictors (DOBPs) per a sistemes dinàmics incerts basats en observadors de pertorbacions. La principal aportació és demostrar que els DOBCs es poden sintetitzar des d'un punt de vista de control òptim; sent el seu principal criteri de disseny el d'aproximar la -irrealitzable- senyal de control òptima que minimitza un índex de cost quadràtic restringit a un model dinàmic lineal (LTI). Aquest nou plantejament és indistintament vàlid per a models SISO/MIMO amb múltiples o úniques pertorbacions. A més permet un ajust del controlador molt intuïtiu gràcies a les matrius de ponderació del cost. De manera similar; els DOBPs es construeixen amb l'objectiu d'aproximar la solució temporal un sistema dinàmic pertorbat. Amb l'objectiu de contextualitzar l'aportació, el document també inclou un breu resum dels principals mètodes de control robust i l'impacte que han tingut en la revolució tecnològica del segle XXI; algunes discussions sobre la utilitat dels models LTI pertorbats per a representar sistemes dinàmics incerts; i algunes relacions, comparacions i simulacions numèriques dels mètodes proposats amb altres tècniques de control.
[EN] Engineering or physical systems are used to be uncertain. Its uncertainty is manifested whenever the system shows behaviors that are relatively different than the ones predicted by its model; being mostly caused by: modeling errors; unknown dynamics; changes in the system properties; random interactions with other systems; or changes in the operating conditions. Through the last 40 years, it has been persistently proved that the system uncertainties could have very negative effects in the performance of a feedback regulator if they are not properly considered in the mathematical formulations of the employed algorithms. Thus, an important part of the recent research is focused on this topic; searching for the most appropriate ways to mathematically represent the system uncertainties and looking for new mathematical-tools that permit to make use of such uncertainty-representation in order to design robust control algorithms. In this thesis, new contributions in this line are provided. Concretely, novel methodologies to design Disturbance Observer-Based Controllers (DOBCs) and Predictors (DOBPs) for uncertain dynamic systems are developed. The main contribution is to show that the DOBCs can be constructed from an optimality-based approach, with the main objective of approximating the -unrealizable- optimal control signal that minimizes a quadratic-cost performance index subject to a LTI disturbed model constraint. This novel robust control design is indistinctly valid for SISO/MIMO models with single/multiple matched/mismatched disturbances; offering also a highly intuitive and versatile tuning through the weighting matrices. Similarly, the DOBPs are synthesized in order to approximate the time-domain solution of LTI disturbed models. For the sake of completeness, the document also includes a brief review of the main robust control methods and the impact that they have had on the technological revolution of the 21st century; some discussions about the usefulness of the LTI disturbed models for representing uncertain dynamic systems; and different relationships, comparisons and numerical simulations, of the proposed methods with other control approaches.

Повний текст джерелаEn aquesta tesi doctoral, s’han descobert nous pèptids com a lligands del factor de creixement endotelial (EGF) i com a noves llançadores peptídiques, usant les tècniques de phage display i la síntesi química de pèptids. EGF es troba sobre-expressat en diversos càncers i, mitjançant la seva inhibició, la proliferació d’aquestes cèl·lules es podria reduir. Amb phage display es poden trobar aquests lligands, però els fags només poden expressar pèptids L, els quals són degradats per proteases. En el mirror image phage display, la selecció es duu a terme contra la imatge especular de la diana original i, després de la selecció i la síntesi dels enantiòmers dels millors candidats, s’obtenen pèptids D com a lligands. En aquest context, l’enantiòmer de EGF s’ha sintetitzat usant una combinació de síntesi en fase sòlida i lligació química nativa. Després del procés de selecció amb dos biblioteques de fags contra la proteïna immobilitzada, nou seqüencies s’han seleccionat i sintetitzat amb aminoàcids D. Tres d’aquests pèptids presenten altes estabilitats i afinitats per EGF. La majoria de fàrmacs pel tractament de malalties del sistema nerviós central no creuen la barrera hematoencefàlica. Una alternativa és l’ús de llançadores, que tenen la capacitat de transportar fàrmacs al cervell. La metodologia de phage display s’ha aplicat en un model humà de la barrera hematoencefàlica i, després del cribratge, la seqüència SGVYKVAYDWQH (SGV) s’ha seleccionat. Estudis de validació s’han dut a terme confirmant que SGV és capaç d’incrementar el transport d’una proteïna en cèl·lules endotelials. Hi ha casos en que la modificació del fàrmac amb una sola llançadora no és suficient per creuar la barrera hematoencefàlica. En aquest sentit, s’ha explorat la dimerització d’una llançadora (THRre) per incrementar el transport de proteïnes. Els resultats obtinguts suggereixen un moderat increment en el transport, el qual pot no compensar l’esforç sintètic requerit. La clorotoxina (CTX), pèptid trobat en el verí d’un escorpí, i versions reduïdes d’aquesta (MiniCTXs), s’han estudiat com a nova font de llançadores. Les propietats d’aquests pèptids de creuar la barrera hematoencefàlica han estat avaluades. Al final d’aquest procés, dos MiniCTXs han estat seleccionades, amb uns valors de transport semblants a les millors llançadores.

Por ello, la presente tesis doctoral se centra en el diseño de una novedosa solución de carácter general para gestionar el entorno de un vehículo que cubra tanto los aspectos teóricos como prácticos relacionados con la percepción del contexto vehicular. Esta nueva solución Context-Awareness dentro del contexto vehicular ha sido llamada Intra-vehicular Context Awareness (IvCA). En este sentido, la linea de trabajo ha tenido dos vertientes. Por un lado, se diseñó un modelo de carácter general del contexto de un vehículo. Por otro lado, se ha realizado un enfoque práctico con el fin de desarrollar diferentes soluciones para percibir dicho modelo contextual.
The development of on-board services in the vehicular scope is an important line of work in the ITS field. In this scope, the perception of the context is a paramount factor so as to come up with more complex and advanced services. Thus, the present PhD thesis pursues to define a general-purpose platform to perceive the context related to a vehicle given a familiar scope. In that sense, the line of work has been twofold. On the one hand, a general model for the context of a vehicle has been designed. On the other hand, a practical approach has been carried out to develop several solutions to perceive the target context model. These solutions have been implemented by mainly taking advantage of low-cost equipments a common vehicle includes by default.

Повний текст джерелаIn this research the notion of desire presented in Plato’s, Freud’s and Lacan’s works will be thoroughly examined. The hypothesis considered here is that the Freudian and lacanian approaches offer a potential answer to the current return of the individual and the human in contrast to the use of universal knowledge which pretends subjugate desire by means of referring to those notions of normality and the pathological. Due to this, the aim in this research is to update the notion of desire in the current crisis of the contemporary subject, as well as analyze its possible relation with the other – that is, the otherness existing within the social and political arena. The point of departure has been the analysis of the erotic dialectics to be found in Plato’s Symposium. We have developed the criticisms of Plato towards the oral tradition, as well as towards sophistics, medicine, comedy and tragedy, due to the fact that this allows us establishing a close connection between politics and knowledge, good government and truth. Once the techniques of control typical of the platonic era are presented –enkrateia – we have established a close relation between Plato’s notions and the more contemporary notion of biopolitics introduced by Foucault. We have also developed the freudian and lacanian conceptions concerning the linguistic structure of desire and the unconscious subject –in contrast to the classical cartesian subject. This allowed us to establish the difference between desire – as a notion which is constitutive of the individual as such– and the factory of desires that the consumer society actually is –and which is analyzed as a result of departing of the notions of fetishism and merchandise.

The communication problem found was an interface design that did not contribute to the motorcycle taxi user experience and nor did it solve the problem of informality in the district. Taking into account that currently more than 8,000 thousand smaller vehicles circulate, of which only 2,800 are formal. This problem becomes relevant for graphic design because we find flaws in the UI design and also the need for a graphic system where the user can visually identify a formal motorcycle taxi. The solution proposal is an improvement to the application, giving it the main function of ordering a motorcycle taxi, and creating a whole graphic system that supports the identification of formal vehicles. The results yielded a better user experience, making it a faster and safer option.

It seeks to analyze the characteristics of the system, identify the needs regarding its mobility and the mode of impact. It was proposed as a hypothesis that the environmental signage and graphic design system has deficiencies that have a social impact on the lives of people with visual disabilities. The most functional for this research is a qualitative approach, a space and a certain group are analyzed, through observation, field research, visual analysis and experiences. Visual documentation and frequency lists and checklists were collected. The main findings were that the system does indeed have deficiencies that make it a limited and non-inclusive service, causing inaccessibility to transportation. Consequently, there is a restriction of social participation, difficulty of being able to satisfy daily needs and desires. To conclude, the system does impact on the mobility of these people, affects their personal development by not being able to meet daily needs and their social and inclusive development since, through mobility in spaces there is interaction, such as doing activities or meet, talk, be with another. In addition, it is proposed to create a solution with a universal design, which is not exclusive to people with physical disabilities, but is suitable for everyone.

Повний текст джерелаAbstract. Currently, there is an increase in the demand for tall buildings in the city of Lima. This research proposes to reduce the dynamic amplification factor through the seismic design of tall buildings based on the requirements of Peruvian code considering that they are regular in plan and height. Mini-mum base shear values according to the comparison of static seismic shear and dynamic shear from spectral modal analysis were reviewed for cases of buildings larger than 120 meters. The study of 28 reinforced concrete build-ings was proposed, with different heights - varying from 24 to 36 floors, with different floor configurations, as well as the arrangement of the walls considering as a rigid core structural system. Additionally, the characteristics of the materials, the loads and combinations were defined. The responses of these buildings were determined by the response spectrum analysis (RSA) and then compared with those obtained by the lineal response history analy-sis (LRHA), for the last analysis, five Peruvian seismic records were used and scaled to 0.45g. The seismic responses of the LRHA procedure were taken as benchmark. The result of this study is the analysis and proposal of the C / R factor for high-rise buildings, as well as obtaining the base shear and drift verification. Minimum base shear values can be reduced for high or long-term buildings, being regular in plan and height.

Para acceder a estos sistemas se han desarrollado dos metodologías sintéticas para la obtención de 2-amino-6-aril-5,6-dihidropirido[2,3-d]pirimidin-4,7(3H,8H)-dionas y de 6-aril-2-metiltio-5,6- dihidropirido[2,3-d]pirimidin-4,7(3H,8H)-dionas. Posteriormente, se ha puesto a punto una estrategia sintética para la derivatización de estos sistemas pirido[2,3-d]pirimidínicos en las posiciones C2, C4, C6 y N8 y la deshidrogenación del enlace entre las posiciones C5 y C6 del sistema. Una vez se ha desarrollado satisfactoriamente esta ruta de síntesis que permite la obtención de pirido[2,3-d]pirimidinas con hasta cuatro puntos de diversidad, se ha procedido a acceder a una quimioteca amplia de estos tipos de sistemas los cuales se han evaluado la actividad biológica frente al VHC. Los valores de EC50 y CC50 determinados han permitido modular la estructura de los compuestos con el fin de mejorar el valor de actividad y disminuir, a la vez, la toxicidad de los compuestos. Así se ha obtenido la 2-(fenilamino)-6-(4-fluorofenil)pirido[2,3-d]pirimidin- 4,7(3H,8H)-diona con una EC50 = 23 nM y un índice de selectividad de 393.
In the present work a family of 7-oxopyrido[2,3-d]pyrimidines has been developed as potential inhibitors against the Hepatitis C Virus (HCV). To achieve such systems, two synthetic methodologies were developed for the synthesis of 2- amino-6-aryl-5,6-dihydropyrido[2,3-d]pyrimidine-4,7(3H,8H)-diones and 6-aryl-2-(methylthio)- 5,6-dihydropyrido[2,3-d]pyrimidine-4,7(3H,8H)-diones. Subsequently, a synthetic strategy was developed to derivatize these pyrido[2,3-d]pyrimidines at C2, C4, C6, and N8 positions and carry out the dehydrogenation of the C5-C6 bond. After the successful development of such synthetic route allowing the preparation of pyrido[2,3- d]pyrimidines with up to four diversity centers, a wide library of these compounds was prepared and, subsequently, their biological activity against HCV was evaluated. The EC50 and CC50 values determined have allowed the modulation of the structure of these compounds in order to improve the activity value and lower the toxicity. Thus, the 6-(4-fluorophenyl)-2- (phenylamino)pyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione was obtained presenting a EC50 = 23 nM and a selectivity index of 393.

The project aimed to increase the satisfaction of operators by reducing the time of attention of Human Capital service. The present study becomes the first example of the application in the area of Human Resources (HR) of Peru's consumer goods industry, due to no evidence of application of DT in projects designed for operators was found. Applied research were used, applying the case study under a mixed approach. Which includes the qualitative when using DT techniques, which avoids falling into the error of building a solution based on ungrounded premises. The information collection techniques used were: observation, in-depth interviews and the analysis of documents. Regarding the quantitative approach, it applied through surveys and perception tests. Among the limitations of the research is the lack of documentation on the application of the DT in HR projects, as well as the difficulty of quantifying results (creativity / financial return). Results obtained shows that DT applied to the design of an Information System increased employee satisfaction from 51.5% to 79.4%. Therefore, it is concluded DT increased employee satisfaction and improved productivity by prioritizing human interaction. Likewise, it propitiated spaces of co-creation and vectors of change that accelerated the creation of value.

Повний текст джерелаAt present, the coverage of drinking water in the country is still insufficient, especially in rural areas of the country; similarly, this problem occurs in the peri-urban areas of Lima. Such as the La Rinconada area of Pamplona Alta which is located in the San Juan de Miraflores district that does not have a basic potable water service, the supply of this resource is done by tank trucks and stored in tanks, drums, buckets, etc. It is for this reason that the present investigation proposes a design proposal for the potable water supply system for the study area, for which it is taken into consideration that the required flow will be provided by SEDAPAL. Because the topography of the study area presents steep slopes, it is necessary to use pressure reducing valves, which are localized through the application of the Multiobjective Genetic Algorithm, which in its coding includes the use of the Epanet Programmer's Toolkit, which comes to be a dynamic library (DLL) of functions that allows programmers to customize the EPANET calculation engine for their specific needs. In this sense, the method used proposes a proposal for improvement in the design process of the potable water supply system in La Rinconada de Pamplona Alta in the district of San Juan de Miraflores. For which, the EPANET program was used in the simulation and hydraulic calculation of the distribution network as it is a program of proven effectiveness and free use. On the other hand, the result of the hydraulic analysis of drinking water projects carried out in the country either by iterative manual methods or with the help of simulation programs, often does not meet the requirements of the range of admissible pressures established by the Regulation. National Building, which translates on the one hand in costs of carrying out maintenance programs that supply these deficiencies and on the other hand possible pipe breaks or water leaks due to high pressures. That is why it seeks to meet the requirements of the design standards and at the same time provide adequate service pressure, for which the Multiobjective Genetic Algorithm is used in the design of the network for the study area, which it would lead to savings in operation and maintenance costs. Finally, the proposed design for the drinking water supply system in La Rinconada de Pamplona Alta is made up of the RAP-1 reservoir that supplies four pressure zones through an adduction line and the RRP-3 reservoir that supplies another line of water. adduction to three pressure zones because the topography presents considerable differences in level. Additionally, with the use of a subprogram included in the Multiobjective Genetic Algorithm, it was possible to assign the demand flows automatically in all nodes of the distribution network contributing to the improvement in the design process through the EPANET program.

En aquest context, les empreses, organitzacions i institucions es veuen obligades a treballar la seva pròpia imatge i comunicació de forma eficaç, des de la disciplina de la identitat visual corporativa. També les organitzacions no governamentals (ONG) s'han sumat a aquesta dinàmica impulsades per l'augment de la competència en el sector i la necessitat de recaptar recursos que els permeten continuar amb la seua tasca. El present treball es situa en el marc de la identitat visual corporativa de les ONG espanyoles, baix el context que des de 2015 assenyala a les institucions i als individus un repte universal cap a la millora de la vida: els Objectius de Desenvolupament Sostenible de l'Agenda 2030. En aquest escenari es proposen dos objectius generals: analitzar i valorar la situació actual de les marques i generar propostes de millora en el camp del disseny i la gestió de la marca. Per a això, amb el binomi marca i ONG com a eix central, s'ha desenvolupat un model sistèmic per al disseny i creació d'una marca, s'ha avaluat l'eficàcia de les marques tant dels noms de marca a partir de criteris lingu¿ístics com del seu aspecte formal, s'ha analitzat l'ús de la marca com a imatge de perfil en xarxes socials i s'ha estudiat la utilització i viabilitat dels manuals d'identitat visual corporativa com a instrument de coordinació de l'ús de la marca. Els resultats mostren que les ONG espanyoles presenten, en general, un compliment insuficient dels criteris d'eficàcia d'una identitat visual, tant des del punt de vista del nom i marca gràfica com per la gestió i aplicació a diferents suports. Per tot això es plantegen un seguit de recomanacions per millorar l'eficàcia del disseny, ús i gestió de la identitat visual corporativa de les marques de les ONG que permeten augmentar l'eficàcia de la seua comunicació corporativa i de les seues actuacions en l'àmbit solidari.
[EN] Currently we are surrounded by endless messages and visual stimuli that change at a frenetic pace that require immediate interactivity. In this context, companies, organizations and institutions are forced to work theirb own image and communication effectively, from the discipline of corporate visual identity. Non-governmental organizations (NGOs) have also joined this dynamic driven by increased competition in the sector and the need to raise resources to enable them to continue their work. This work is situated within the framework of the corporate visual identity of Spanish NGOs, in the context that since 2015 indicates to institutions and individuals a universal challenge towards the improvement of life: the Sustainable Development Goals of the 2030 Agenda. In this scenario, two general objectives are proposed: to analyze and assess the current situation of the brands and to generate proposals for improvement in the field of brand design and management. To do this, with the brand and NGO binomial as the central axis, a systemic model for the design and creation of a brand has been developed, the effectiveness of brands has been evaluated, both of brand names based on linguistic criteria and their formal aspect, the use of the brand as a profile image in social networks has been analyzed and the use and viability of corporate visual identity manuals as an instrument for coordinating the use of the brand have been studied. The results show that Spanish NGOs manifest, in general, insufficient compliance with the criteria for the efficacy of a visual identity, both from the point of view of the name and graphic brand and by the management and application to different media. For all these reasons, a series of recommendations are made to improve the effectiveness of the design, use and management of the corporate visual identity of NGO brands that allow for greater efficiency in corporate communication and actions in the field of solidarity.

Повний текст джерела[CAT] L'aprenentatge automàtic (ML per les seues sigles en anglés) és conegut com la branca de la intel·ligència artificial que reuneix algorismes estadístics, probabilístics i d'optimització, que aprenen empíricament. ML pot aprofitar el coneixement i l'experiència que s'han generat durant anys en les empreses per a realitzar automàticament diferents processos. Per tant, ML s'ha aplicat a diverses àrees d'investigació, que estudien des de la medicina fins a l'enginyeria del programari. De fet, en el camp de l'enginyeria del programari, el manteniment i l'evolució d'un sistema abasta fins a un 80% de la vida útil del sistema. Les empreses, que s'han dedicat al desenvolupament de sistemes programari durant molts anys, han acumulat grans quantitats de coneixement i experiència. Per tant, ML resulta una solució atractiva per a reduir els seus costos de manteniment aprofitant els recursos acumulats. Específicament, la Recuperació d'Enllaços de Traçabilitat, la Localització d'Errors i la Ubicació de Característiques es troben entre les tasques més comunes i rellevants per a realitzar el manteniment de productes programari. Per a abordar aquestes tasques, els investigadors han proposat diferents enfocaments. No obstant això, la majoria de les investigacions se centren en mètodes tradicionals, com la indexació semàntica latent, que no explota els recursos recopilats. A més, la majoria de les investigacions s'enfoquen en el codi, descurant altres artefactes de programari com són els models. En aquesta tesi, presentem un enfocament basat en ML per a la recuperació de fragments en models (FRAME). L'objectiu d'aquest enfocament és recuperar el fragment del model que realitza millor una consulta específica. Això permet als enginyers recuperar el fragment que necessita ser traçat, reparat o situat per al manteniment del programari. Específicament, FRAME combina la computació evolutiva i les tècniques ML. En FRAME, un algorisme evolutiu és guiat per ML per a extraure de manera eficaç diferents fragments d'un model. Aquests fragments són posteriorment avaluats mitjançant tècniques ML. Per a aprendre a avaluar-los, les tècniques ML aprofiten el coneixement (fragments recuperats de models) i l'experiència que les empreses han generat durant anys. Basant-se en l'aprés, les tècniques ML determinen quin fragment del model realitza millor una consulta. No obstant això, la majoria de les tècniques ML no poden entendre els fragments dels models. Per tant, abans d'aplicar les tècniques ML, l'enfocament proposat codifica els fragments a través d'una codificació ontològica i evolutiva. En resum, FRAME està dissenyat per a extraure fragments d'un model, codificar-los i avaluar quin realitza millor una consulta específica. L'enfocament ha sigut avaluat a partir d'un cas real proporcionat pel nostre soci industrial (CAF, un proveïdor internacional de solucions ferroviàries). A més, els seus resultats han sigut comparats amb els resultats dels enfocaments més comuns i recents. Els resultats mostren que FRAME va obtindre els millors resultats per a la majoria dels indicadors de rendiment, proporcionant un valor mitjà de precisió igual a 59.91%, un valor mitjà d'exhaustivitat igual a 78.95%, una valor-F mig igual a 62.50% i un MCC (Coeficient de Correlació Matthews) mig igual a 0.64. Aprofitant els fragments recuperats dels models, FRAME és menys sensible al coneixement tàcit i al desajustament de vocabulari que els enfocaments basats en informació semàntica. No obstant això, FRAME està limitat per la disponibilitat de fragments recuperats per a dur a terme l'aprenentatge automàtic. Aquesta tesi presenta una discussió més àmplia d'aquests aspectes així com l'anàlisi estadística dels resultats, que avalua la magnitud de la millora en comparació amb els altres enfocaments.
[EN] Machine Learning (ML) is known as the branch of artificial intelligence that gathers statistical, probabilistic, and optimization algorithms, which learn empirically. ML can exploit the knowledge and the experience that have been generated for years to automatically perform different processes. Therefore, ML has been applied to a wide range of research areas, from medicine to software engineering. In fact, in software engineering field, up to an 80% of a system's lifetime is spent on the maintenance and evolution of the system. The companies, that have been developing these software systems for a long time, have gathered a huge amount of knowledge and experience. Therefore, ML is an attractive solution to reduce their maintenance costs exploiting the gathered resources. Specifically, Traceability Link Recovery, Bug Localization, and Feature Location are amongst the most common and relevant tasks when maintaining software products. To tackle these tasks, researchers have proposed a number of approaches. However, most research focus on traditional methods, such as Latent Semantic Indexing, which does not exploit the gathered resources. Moreover, most research targets code, neglecting other software artifacts such as models. In this dissertation, we present an ML-based approach for fragment retrieval on models (FRAME). The goal of this approach is to retrieve the model fragment which better realizes a specific query in a model. This allows engineers to retrieve the model fragment, which must be traced, fixed, or located for software maintenance. Specifically, the FRAME approach combines evolutionary computation and ML techniques. In the FRAME approach, an evolutionary algorithm is guided by ML to effectively extract model fragments from a model. These model fragments are then assessed through ML techniques. To learn how to assess them, ML techniques takes advantage of the companies' knowledge (retrieved model fragments) and experience. Then, based on what was learned, ML techniques determine which model fragment better realizes a query. However, model fragments are not understandable for most ML techniques. Therefore, the proposed approach encodes the model fragments through an ontological evolutionary encoding. In short, the FRAME approach is designed to extract model fragments, encode them, and assess which one better realizes a specific query. The approach has been evaluated in our industrial partner (CAF, an international provider of railway solutions) and compared to the most common and recent approaches. The results show that the FRAME approach achieved the best results for most performance indicators, providing a mean precision value of 59.91%, a recall value of 78.95%, a combined F-measure of 62.50%, and a MCC (Matthews correlation coefficient) value of 0.64. Leveraging retrieved model fragments, the FRAME approach is less sensitive to tacit knowledge and vocabulary mismatch than the approaches based on semantic information. However, the approach is limited by the availability of the retrieved model fragments to perform the learning. These aspects are further discussed, after the statistical analysis of the results, which assesses the magnitude of the improvement in comparison to the other approaches.

L'idea di sostituire un singolo satellite con sistemi satellitari formati da più unità, in generale, ha il risultato di ridurre i costi di sviluppo, di garantire maggiore robustezza alle avarie, un maggiore livello di flessibilità e migliori prestazioni di misura. In aggiunta, la prospettiva di estendere il periodo operativo di sistemi satellitari attualmente in orbita attraverso operazioni di ispezione, manutenzione e riparazione, apre la possibilità di ottenere grandi vantaggi da un punto di vista economico. Tuttavia, i citati vantaggi si scontrano con la necessità di sviluppare adeguate strategie di Guida, Navigazione e Controllo (GN&C) con requisiti non solo sulla dinamica assoluta di ogni satellite, ma anche sul loro stato relativo. Questo aspetto spinge ricercatori e istituzioni allo sviluppo di adeguate tecniche di GN&C che permettano l'esecuzione autonoma e affidabile di manovre coordinate tra più satelliti in orbita. Perché una nuova proposta o strategia sia considerata matura per essere impiegata in uno scenario spaziale, è necessario dimostrarne l'affidabilità e l'efficacia in un ambiente rappresentativo di quello spaziale. Una delle più interessanti metodologie per raggiungere questo obiettivo prevede l'utilizzo di simulatori satellitari di terra. Il presente lavoro si focalizza sullo sviluppo di strategie di stima basate su sistemi di visione per la gestione delle fasi di navigazione relativa tra satelliti nell'ambito del volo in formazione e, più generale, delle operazioni di prossimità che coinvolgano due o più satelliti. Con il fine di validare le strategie di GN&C sviluppate, parte delle mie attività ha riguardato lo sviluppo e la realizzazione del simulatore satellitare di terra, chiamato SPARTANS, in sviluppo dal 2010 presso il Centro di Ateneo di Studi e Attività Spaziali (CISAS) "G. Colombo" dell'Università di Padova. Questo simulatore satellitare presenta unità robotiche che permettono di simulare a terra moti relativi, sia rotazionali che traslazionali, tra unità satellitari operanti in formazione o in prossimità. Questa caratteristica fondamentale permette la validazione, da un punto di vista sperimentale, delle strategie di GN&C sviluppate. La prima attività svolta durante il mio dottorato riguarda la caratterizzazione, da un punto di vista metrologico, di un sistema di visione monoculare utilizzato per stime di posa relative nel contesto di satelliti cooperanti. Un contributo originale consiste nella proposta di un set di 'fiducial markers' per i quali è stata sviluppata un apposita procedura di analisi d'immagine con lo scopo di estrarre punti salienti dalle immagini acquisite. La procedura di stima della posa si basa sulla soluzione del problema noto come 'Perspective-from-Three Points' (P3P), soluzione che successivamente viene raffinata per via di una procedura iterativa, seguita a sua volta da un'ottimizzazione non lineare. La caratterizzazione dell'algoritmo di misura proposto segue un approccio sperimentale: un modello semplificato, rappresentativo della geometria di un satellite è impiegato come satellite target la cui posa, in relazione al sistema di visione, rappresenta l'incognita da stimare. Al satellite target, in questo contesto, sono imposti spostamenti noti sia in termini traslazionali che rotazionali e, attraverso il confronto tra gli stati imposti e quelli misurati, viene determinato l'errore di stima. Infine un'analisi di incertezza è stata effettuata fornendo indicazioni, supportate dai risultati della campagna di test sperimentali, sull'accuratezza media di stima che risulta essere dell'ordine di 1 cm e di 1° sulla posizione e sull'orientazione relativa rispettivamente. La seconda attività del mio dottorato riguarda lo sviluppo e l'implementazione di nuove funzionalità per il simulatore SPARTANS. All'inizio del mio dottorato, il setup sperimentale consisteva di una sola unità satellitare capace di effettuare manovre d'assetto a tre assi utilizzando come dati di navigazione le misure fornite da un sistema di encoder ottici in quadratura, e eseguendo azioni di controllo grazie a un sistema di thrusters a gas freddo. In una prima fase, ho fornito un piccolo contributo allo sviluppo del Modulo di Traslazione (TM), che abilita spostamenti planari a basso attrito per le unità satellitari, e alla progettazione e sviluppo di una tavolo piano per il laboratorio che fornisce di fatto la base su cui le unità satellitari possono traslare. Successivamente, il mio apporto si è focalizzato sull'implementazione delle componenti hardware per di laboratorio. In particolare l'attività principale in questo contesto riguarda la progettazione, l'implementazione e la caratterizzazione di un sistema di navigazione globale con lo scopo di stimare la posizione e l'orientazione delle unità satellitari all'interno del volume operativo del laboratorio. Quest'attività consiste di due fasi principali. Dapprima un prototipo a basso costo è stato realizzato utilizzando come sensori un sistema di visione monoculare accoppiato a un set di tre sensori ottici di tipo mouse (Optical Flow Sensors - OFS) per stimare la posa planare del TM. La strategia di stima si basa su due set di misure, fornite con diverse frequenze di acquisizione, le quali sono fuse opportunamente per mezzo di un filtro di Kalman esteso (Extended Kalman Filter - EKF). La seconda fase di sviluppo estende lo schema di stima sviluppato adattandolo al setup complessivo del laboratorio. Nel fare questo, il sistema monoculare è sostituito da un sistema di Motion Capture composto da sei camere operanti nell'infrarosso e da una Control Station. In questo contesto, una strategia per la stima della posa delle unità satellitari è proposta assieme alla definizione di una procedura di calibrazione per il sistema di Motion Capture. I risultati ottenuti attestano la capacità dell'approccio di misura di fornire stime di posa con incertezze inferiori al millimetro sulla posizione e al grado sull'orientazione. Nella parte finale del mio dottorato, le mie attività si sono incentrate sullo sviluppo di una strategia di stima per la navigazione relativa tra due spacecraft basata su un filtro di Kalman esteso (EKF), il quale incorpora solamente le misure fornite da un sistema di visione stereo montato a bordo del satellite chaser. L'approccio alla stima presuppone che la geometria del target sia nota nel momento in cui le manovre di prossimità hanno inizio. Nell'ottica di una futura implementazione dello schema di filtraggio a bordo delle unità satellitari del simulatore di terra, il filtro è stato scritto in linguaggio C/C++. Le prestazioni del filtro di navigazione sviluppato sono quindi valutate in due differenti scenari. Nel primo scenario, il filtro è applicato ad un contesto spaziale nel quale il moto orbitale di due satelliti è riprodotto per via numerica. Nel secondo caso invece, le condizioni operative del setup di laboratorio sono modellate in un ambiente di simulazione 3D. La strategia di navigazione è in ultima istanza testata per via sperimentale grazie all'utilizzo del simulatore satellitare. L'algoritmo di navigazione proposto dimostra di essere capace di stimare lo stato relativo tra i due satelliti con accuratezze dell'ordine del centimetro sulla posizione e del grado sull'orientazione. Nello stato attuale, il simulatore satellitare di terra SPARTANS si compone di un'unità satellitare completa, di un tavolo di test con una superficie di 3x2 m, di un sistema di navigazione globale basato sul sistema di Motion Capture e di una Control Station esterna. Nel momento in cui la costruzione della seconda unità satellitare sarà ultimata, il simulatore permetterà l'esecuzione di manovre coordinate per l'investigazione e lo studio di problematiche relative a volo in formazione, rendez-vous and docking e, in generale, manovre di prossimità.
