Full textPeru presents various eventualities such as rainfall, which delay different activities that promote the country's economic growth. Urban areas need continuous improvement of the environment with better infrastructure to promote growth and reduce accidents. At present, innovative solutions for the evacuation of high rainfall need to be promoted through the local environment. Permeable concrete is a type of concrete whose technology allows water to flow through its structure due to the high porosity it possesses, unlike traditional concrete. It is made of coarse aggregate and cementitious material, with a low percentage of fines of up to 10%. This research consists in proposing a permeable concrete mix design of f'c = 175kg / cm² applied in sidewalks that satisfies different requirements established by the CE010 standards of Urban Pavements, ACI 211.3R, ACI 522R-10 and those of the area of application. For this, a battery of 12 mixing designs with a / c ratios of 0.30, 0.35 and 0.38; aggregates of HUSO 7 and 67; portland cements type 1 Sol and Quisqueya; and fluidizing Z additive SR. Fresh tests were performed: Slump, volumetric weight and void content; and in a hardened state: resistance to compression and flexion, and permeability. Finally, a prototype was made with the design that presented better characteristics with the purpose of validating the research and a comparison was made between the permeable and traditional concrete sidewalks.

Full textThe present investigation mentions the laboratory analysis regarding the placement of asphalt at a temperature below six degrees centigrade, taking into account that Peru has different types of climates throughout its territory, this makes the asphalt production and its placement is a difficulty for any type of road project, which leads us to a reality in the production of hot asphalt, since knowing the standards we currently have, that makes placement impossible to a temperature below six degrees centigrade. The research is focused on a qualitative - quantitative analysis which must comply with the quality parameters (Tests), road manual (EG - 2013) and constructive process (Marshall method) the realization of the asphalt mix proposal will vary in the percentage of different types of filler that we have considered for the research (lime, portland cement type I and silica). For the tests, test tubes were carried out without any type of additives, once the test tubes were prepared at 140ºC, they were subjected to freezing, resulting, of the three types of filler, that the hot asphalt mix with incorporation of portland cement type I at a 5,90% asphalt cement is the optimal one complying with the parameters and technical specifications of the road manual.

Full textPara evitar estos problemas se ha diseñado un modelo matemático de un motor, que comprende todo el proceso de formación de la mezcla, sensores, la generación del par motor y la dinámica del vehículo. La realización final se ha realizado en el lenguaje de simulación MatLab/Simulink®. Los datos requeridos son fácilmente obtenibles bien por metrología, bien de forma experimental. Se ha validado con un motor SEAT de 1,6 l y 74 kW.
Como primer paso se ha aplicado una estrategia de control convencional bastante simple, consistente en un controlador feedforward estático, más un controlador feedback de tipo PI ó PID. Esto ha permitido el estudio de las principales características del motor desde el punto de vista de control.
Con los resultados obtenidos se ha diseñado un observador basado en una red neuronal, que elimine los retardos puros del sistema y que pueda ser utilizado para cerrar el lazo de control. Primero se ha usado una red feedforward, pero vistos los malos resultados, se ha desarrollado una red neuronal recurrente a partir de la red de Elman, que se ha modificado convenientemente para adaptarla a las dificultades propias del problema. El algoritmo de entrenamiento utilizado se basa en el de retropropagación clásico, y modifica no sólo los pesos entre capas, sino también los correspondientes a las neuronas de contexto, las cuales permiten memorizar estados internos. La principal mejora consiste en separar las neuronas de contexto en tantos grupos como entradas tiene la red, y entrenarlos por separado, de modo que cada grupo se adapte a la dinámica particular de la entrada a la que va asociado. Se muestra mediante simulación el comportamiento del conjunto motor más observador en lazo cerrado, y se compara con el esquema convencional. Se prueba asimismo la robustez del sistema frente a distintas consignas, ruido en la planta y defectos de sintonía.
In the present thesis a control system for the air-fuel mixture in a reciprocating four-stroke engine is developed, based on neural networks. The air-fuel ratio has to be kept within a very narrow window so that the catalyst achieves an acceptable degree of purification simultaneously with all the polluting gases. In steady state, this goal can be fulfilled without difficulties, but the usual operation of a vehicle is in a very transient state, where the conventional systems are not able to avoid important excursions from the set point. They also rely on a great number of look-up tables, which have to be tuned experimentally, thus with an enormous investment of money and time.
To avoid those problems a mathematical model of an engine has been designed, in such a way that it comprises of the whole mixture formation process, sensors, the torque generation and the vehicle dynamics. Finally it has been implemented in the simulation language MatLab/Simulink®. The required data is easily available both from metrology, and experimental work. It has been validated with a 1,6 litre 74 kW SEAT engine.
As a first step, a quite simple conventional control strategy has been applied, consisting of a static feedforward controller, and a PI or PID feedback controller. This has permitted studying the main features of the engine from the control point of view.
With the obtained results an observer based on a neural network has been designed, which eliminates the delays of the system and that can be used to close the control loop. First a feedforward network has been used, but due to the bad results, a recurrent neural network has been developed starting from the Elman network, which has been properly modified in order to adapt it to the characteristic difficulties of the problem. The training algorithm used is based on that of classical backpropagation, and it modifies not only the weights interconnecting different layers, but also those corresponding to the context neurons, which allow the memorising of internal states. The main improvement consists in separating the context neurons in as many groups as the network has inputs, and to train them separately, so that each group adapts to the particular dynamics of the input with which it is associated. The behaviour of the engine plus the observer in closed loop is shown by means of simulation, and is compared with the conventional scheme. It is proven the robustness of system response to different set points, noise in the plant and tuning defects.

Full textThis thesis evaluates and analyzes the behavior and physical and mechanical properties of the use of the recycled coarse aggregate obtained from the reuse of a concrete removed on site for the preparation of a new mixture that complies with the Peruvian technical standard and with minimum quality standards. This new mixture was obtained from a sampling of different percentages of replacement of the coarse aggregate (25%, 50% and 100%) where the most optimal will be chosen through the performance obtained from the laboratory tests and thus apply the mixture design chosen for the construction of a sidewalk. In addition, it proposes a management system through a generic flow-gram of how recycled aggregates and other waste could be obtained in a much larger dimension than the current one in order to reduce the amount existing in our capital and therefore help reduce the environmental pollution.

Full textOne of the problems in the transport sector of the city of Lima, is the terrible state in which the pavements are found, due to the high vehicular traffic and the climatic conditions, since in the last years the automobile park has increased in a way exponential, generating the deterioration of the pavements and as a consequence when carrying out the maintenance operations, it causes chaos and vehicular traffic. This thesis seeks the solution to this problem, proposing the design of an asphalt mixture that has the property of self-repair, taking as a starting point the design of the conventional asphalt mixture, to which polymers and fibers of steel wool are incorporated, with the purpose to improve the physical and mechanical behavior, and find the recuperative capacity, controlling the fissures by inducing heat and extending the useful life of the pavements.

Full textPervious concrete is a special type of concrete which allows the passage of water through its structure due to its high percentage of voids unlike traditional concrete. This quality of pervious concrete allows to end the lack of permeability in traditional concrete structures thus preventing structural failures due to flooding and water runoff. This research will seek to find a mix design for pervious concrete to apply it as an alternative road surface for pavements. To verify the above, different mix designs were performed in laboratory to find the design that give us a compressive strength of 210 kg/cm2, the chosen design had the following features: water - cement ratio of 0.38, 13% air content, 1.5% additive superplasticizer and 7% of sand. To validate the research, a prototype was built with the chosen mix design, this prototype had an area of 2 m2 (1m x 2m). The fresh concrete was analyzed for its consistency, density, and void percentage; the hardened concrete was analyzed for its compressive strength, permeability and flexural strength, finally the prototype was load tested. The results indicated that the mix design used in the prototype with compressive strength of 261.58 kg/cm2 and a permeability of 0.01744 m/s can be used as an alternative rolling surface for pavements.

Full textThis project aims to inform the reader about a way in which wasted glass can be used in the construction sector providing benefits for civil engineering. This investigation is carried out using recycled ground glass as an addition to concrete and achieving a mix design with a required compressive strength of 210 kg / cm2 after 28 days of curing and a 3-4 inch slump. To find out the advantages of using recycled ground glass as an addition to concrete, it is necessary to make a comparison between a standard concrete and those added with glass powder. Three types of concrete were proposed with different doses of partial replacement of Type I cement with glass dust, these are 0%, 10% and 20%. Multiple mixing designs were made until reaching the final designs, which comply with a 3 to 4 inch slump and a f’cr of 210 kg / cm2 at 28 days. Then, a unit price analysis for the final designs is carried out and these are compared. Finally, the results show that concrete with 20% replacement has a lower production cost than the rest. Another important result is that, the more glass added to the concrete, the lower its resistance at an early age. In summary, by replacing 20% of the cement with glass dust, an economic benefit can be obtained.

Full textThe subject of this research focuses on the design and evaluation of concrete made from domestic wastewater treated by two different types of biological processes (activated sludge and artificial wetlands) as an alternative to the use of drinking water in the city of Lima. Currently, it is known that the availability of drinking water in the city of Lima is not abundant and future projections indicate that the demand due to population increase will generate water shortage problems. Because of this, it is important to take measures to save this valuable resource in industries that consume more water, such as concrete production. Given this problem, the use of treated wastewater is shown as a possible option to replace drinking water in concrete production. This thesis is developed in 7 chapters detailed below: In Chapter 1, the theoretical framework is presented, which includes the main theoretical bases used. Chapter 2 defines the characteristics of the materials used and the methodology of this investigation. Chapter 3 shows the results of the tests and evaluations carried out. In Chapter 4, the results are verified and then discussed. In Chapter 5 the conclusions are presented and in Chapter 6 the recommendations are detailed. Chapter 7 shows the references of other research cited in this Thesis and, finally the annexes of the thesis are shown. At the end of the investigation, it was determined that concrete made with domestic wastewater treated by the biological process of activated sludge is a feasible alternative to the use of potable water when presenting results similar to those of the control group.

Full textThe accelerated growth of cities and the use of waterproof materials have negatively impacted the hydrological cycle. Heavy rainfall during the rainy season leads to the collapse of sewerage networks in cities with inadequate infrastructure. Such runoff accelerates the deterioration of pavements, in addition to the discomfort and danger due to hydroplaning that impacts pedestrians. Pervious concrete is a suitable material to mitigate these problems due to its property of running water through its pores, in addition to being ecological and sustainable. Since its resistance is less than that of conventional concrete, its use is limited in rigid pavements, therefore the incorporation of fibers would provide better mechanical performance. Through a qualitative analysis of various factors, it was determined that basalt fibers would optimize the behavior of pervious concrete for application in urban pavements. In addition, it was taken into consideration that the soil of the study area is gravel and the required infiltration is 192.22 mm/h. The reference mix design corresponds to similar characteristics with the study area and finally the quantities required in the design of this research are 443.12 kg/m3 of cement, 130.43 l / m3 of water, 135.16 kg/m3 of fine aggregate, 1312.04 kg/m3 of coarse aggregate, 3.99 kg/m3 of superplasticizer additive; added to basalt fibers in percentages of 0%, 0.1%, 0.2% and 0.3% with respect to the mix design.

Full textNowadays the Roller Compacted Concrete (RCC) is a technology that is used around the world for the construction mainly of small dams and the repair of these. The rapidity of the putting in work, the relatively low content of cement and the utilization of mineral additives (fly ashes, fillers, mining residues, etc.) explain the reason for which this material is economically interesting for the construction industry. In the development of this technology and of the RCC mix design, two philosophies have arisen, the Soils or Geotechnical philosophy and the Concrete philosophy. In this Investigation there has been in use the Geotechnical philosophy which considers that the RCC can be treated as a soil tried from the phase of design to its placement and the accomplishment of the field tests of the material, using equipments and familiar procedures to the Soils Mechanics; after placed the RCC should be cured and treated as if it were conventional concrete. On the basis of this principles and bearing in mind that in Peru this technology has not developed widely, a program of investigation was elaborated in order to provide information orientated to know the attributes of the RCC and the basic procedures to conduct the mix design for Compactation's methods of Soils and to identify its possible applications in our country. This research was developed in the laboratories of Structures and Geotechnics of CISMID of the Universidad Nacional de Ingeniería, where the Soil philosophy was used for the RCC mixtures design and tests were developed to determine several of their properties, adapting new equipments to obtain the preparation and compactation of the mixture, similar to the one that will be obtained in the field. The characteristics of the agreggates used in the design were determined in the laboratories of Material Testing and of Soils Mechanics of the Universidad Nacional de Ingenieria. For the diverse designed mixtures different proportions of Portland Type I and Puzolanic Type IP were used, compressive strength and durability tests were done in order to compare the obtained results and to determine the most ideal mix design. In the same way, values of the modulus of elasticity were obtained in different ages, values that will be used as guide of the behavior of this material for other calculations and to evaluate the use of the RCC mixtures in different projects. Test results indicate that the mixtures proportion using geotechnical methodologies provides a viable alternative for RCC design mixtures, an option of solution being created to problems related to the construction of new dams and the rehabilitation of existing dams. The mixtures obtained in this investigation will be used as a model to implement this technology in our country, demonstrating his development on a simple way

Full textTThe tendency to use explosive of great power makes that it is also a necessity the application of new techniques to design the drilling patterns, because is necessary to know the use of the relative bulk strength (RBS) in the present investigation. This theory has it{s base in that the energy of an explosive compared to each other is very different, in the same hole volume, that is why changing in a mine operation, an explosive in use for another of more energy has to keep in mind the difference about the energy of each explosive. This approach also implies that the use of the energy factor should be a daily factor instead of the use of the load factor or power factor, which is used in most of the mining units of our country however the energy factor has many years of validity in the developed countries up to date because it allows to quantify the yield of the energy of the explosive correctly. The RBS allows to modify the original dimensions of the burden (B) and spacing (S) quickly and in this way it allows us to save time and cost in the test rehearsals and error for the implementation of the new dimensions in the field. In the work is carried out a change from ANFO to heavy Anfo 50/50 and it was determined that it can decrease the drilling and blasting costs with a more energetic explosive, as well as it improved the fragmentation obtained using ANFO

Algunos de los ensayos realizados se utilizan para el diseño y control de calidad de mezclas convencionales, tal es el caso del Marshall, Tracción Indirecta o Flexotracción, pero también se utilizaron algunos ensayos menos conocidos pero que aportan información muy valiosa como el UCL , o el Barcelona Tracción Directa BTD.
A través del análisis de toda la información obtenida en este trabajo se ha podido comprobar que las mezclas recicladas pueden alcanzar un comportamiento prácticamente equivalente al de las mezclas convencionales, siempre y cuando se tenga el suficiente cuidado en su diseño, y proceso de fabricación. Por otra parte, se han podido establecer algunos parámetros que serán de gran ayuda para el diseño y control de calidad de las mezclas recicladas en caliente en planta, ayudando al impulso del empleo de esta técnica en los proyectos de construcción y rehabilitación de firmes bituminosos en España.

This research is developed experimentally and includes trials with national and international standards (NTP, ASTM and NTC) in the aggregates, water, concrete in fresh state and concrete in hardened state. In order to analyze the increase of certain properties of the structural elements in contact with aggressive agents, such as sulphates, the benefits of incorporating nanosilica in the concrete mixture with 0.2%, 0.225% and 0.25% are evaluated. Being the second percentage of addition, which shows better workability for a water / cement ratio of 0.45. As a result, it was obtained that the nanosilica concrete (NSC) presents lower air content than the simple concrete mixture (SC). In addition, the resistance to compression and tensile increase in 3.41% and 19.48%, respectively, at the age of 28 days with the addition of nanosilica. Likewise, for the sulphate exposure test, the specimens with nanosilica showed an average deterioration of 50% lower in all its edges compared to the simple concrete specimens. Additionally, the permeability coefficient (k) for both mixtures was analyzed and it was determined that the NSC has a low permeability and the SC a medium permeability.

Full textIn Peru, the most important routes are terrestrial, among which, the most common are roadways, these present many deficiencies due to different factors related to errors in design, construction process and maintenance. Nowadays, in Lima, which has almost a third of the population of Peru, presents a large traffic volume, and this significantly affects the roads, especially in the South, where the pavement is highly exposed to sulfates and the natural subgrades have a relatively low bearing capacity. Considering this, in the south region of Lima appropriate constructions of concrete pavements are necessary, using the correct technology and with optimal materials, so they can provide a quality service with low maintenance. On the other hand, industrial processes should be applied to improve the quality and optimize the investment with efficiency. For all of this, the use of CRCP with pozzolanic cements is proposed. This research carried out the design of eight concrete mixtures with pozzolanic cements type HS and IPM, within which one of them was chosen to be applied as an alternative to improve the durability of rigid pavements in this zone. This design ensures a compressive strength of 310 kg / cm2, a rupture modulus of 35 kg / cm2, a water/cement ratio of less than 0.45 and a slump of 2½” in the workplace, which is ideal for a constructive process with a slip formed paving machine. To validate these main characteristics of the concrete, experiments took place in the laboratory for the concrete in fresh and hardened state. In addition, a cost – benefit analysis comparing different types of pavement (flexible, JPCP y CRCP) was made using the optimal mixture obtained in this research.

En la búsqueda de una solución, se ha optado por la exploración de sistemas basados en superficies digitales interactivas, también conocidas como "tabletops". Este tipo de dispositivos ofrece una interfaz natural mediante la cual los usuarios pueden interaccionar con el sistema realizando gestos con sus propias manos, de manera similar a como se trabajaría sobre una mesa o superficie de trabajo real. Adicionalmente, este tipo de sistemas resulta idóneo en tareas de aprendizaje colaborativo, gracias a que permiten el trabajo simultáneo de varios estudiantes facilitando una comunicación en la forma "cara a cara", de igual modo a como se establecería sobre una mesa de trabajo convencional. Aunque este tipo de dispositivos ha sido previamente utilizado en entornos educativos, su integración en las aulas no ha sido transparente, lo cual sigue generando interferencias. En este sentido, uno de los principales objetivos de la tesis ha sido integrar este tipo de tecnología en las propias aulas de forma ubicua. Para ello se han diseñado y desarrollado sistemas que permiten implementar Espacios de Realidad Mezclada, un subconjunto del concepto más amplio de computación ubicua, los cuales permiten integrar la tecnología en las aulas consiguiendo al mismo tiempo que pase desapercibida. Adicionalmente, se ha desarrollado una arquitectura que permite la extensión de estos espacios de trabajo colaborativo en un modelo distribuido, que permite la interconexión simultanea de distintos dispositivos, los cuales se pueden encontrar en ubicaciones remotas. A diferencia de otras soluciones, el modelo propuesto permite diseñar complejas orquestaciones de aula de forma sencilla y natural, ocultando la complejidad del sistema tanto a alumnos como a profesores. A este respecto, con el objetivo de simplificar los procesos de manejo e intercambio de información entre los distintos grupos de trabajo, se ha dotado al sistema de la capacidad de interacción mediante la utilización de manipuladores tangibles de información. De forma paralela, se ha desarrollado un novedoso método y tecnología que permite definir y utilizar elementos tangibles pasivos sobre superficies digitales interactivas implementadas mediante marcos ópticos. Por otra parte, con el objetivo de lograr la máxima simplificación en los procesos de manejo de la información, el sistema ofrece múltiples vías de introducción de nuevos contenidos, ofreciendo formas y métodos que permiten la digitalización de la información de una forma sencilla y natural, estableciendo una relación sencilla y transparente entre el mundo real y el virtual, contribuyendo de este modo a la generación de los Espacios de Realidad Mezclada. En la misma línea, siguiendo una estrategia BYOD ("Bring Your Own Device"), el sistema permite la utilización de cualquier dispositivo smartphone, o similar, para la adición de nueva información. Finalmente, un aspecto destacable de la tesis ha consistido en la evaluación de forma rigurosa de los anteriores sistemas sobre numerosos contextos educativos reales, desde el punto de vista de tres parám
[CAT] El desenrotllament de la tecnologia ha repercutit indubtablement de forma positiva en els processos educatius, oferint principalment noves formes d'accés, organització i enteniment de la informació, i noves vies de comunicació entre alumnes i professors que faciliten la implementació de paradigmes educatius basats en idees constructivistes i aprenentatge col¿laboratiu. No obstant això, la tecnologia pot suposar al mateix temps una barrera en el procés d'enseñanza/aprendizaje, en el fet que pot crear interferències en el mateix. En resposta a esta problemàtica, en esta tesi es pretén aportar solucions basades en la utilització d'Interfícies Naturals d'Usuari, que permeten un aprofitament de les possibilitats de la tecnologia en el procés educatiu, evitant al màxim qualsevol tipus d'interferència en el mateix. En la busca d'una solució, s'ha optat per l'exploració de sistemes basats en superfícies digitals interactives, també conegudes com "tabletops". Este tipus de dispositius oferix una interfície natural per mitjà de la qual els usuaris poden interaccionar amb el sistema realitzant gestos amb les seues pròpies mans, de manera semblant a com es treballaria sobre una taula o superfície de treball real. Addicionalment, este tipus de sistemes resulta idoni en tasques d'aprenentatge col¿laboratiu, gràcies a què permeten el treball simultani de diversos estudiants facilitant una comunicació en la forma "cara a cara", de la mateixa manera a com s'establiria sobre una taula de treball convencional. Encara que este tipus de dispositius ha sigut prèviament utilitzat en entorns educatius, la seua integració en les aules no ha sigut transparent, la qual cosa continua generant interferències. En este sentit, un dels principals objectius de la tesi ha sigut integrar este tipus de tecnologia en les pròpies aules de forma ubiqua. Per a això s'han dissenyat i desenrotllat sistemes que permeten implementar Espais de Realitat Mesclada, un subconjunt del concepte més ampli de computació ubiqua, els quals permeten integrar la tecnologia en les aules aconseguint alhora que passe desapercebuda. Addicionalment, s'ha desenrotllat una arquitectura que permet l'extensió d'estos espais de treball col¿laboratiu en un model distribuït, que permet la interconnexió simultanieja de distints dispositius, els quals es poden trobar en ubicacions remotes. A diferència d'altres solucions, el model proposat permet dissenyar complexes orquestracions d'aula de forma senzilla i natural, ocultant la complexitat del sistema tant a alumnes com a professors. A este respecte, amb l'objectiu de simplificar els processos de maneig i intercanvi d'informació entre els distints grups de treball, s'ha dotat al sistema de la capacitat d'interacció per mitjà de la utilització de manipuladors tangibles d'informació. De forma paral¿lela, s'ha desenrotllat un nou mètode i tecnologia que permet definir i utilitzar elements tangibles passius sobre superfícies digitals interactives implementades per mitjà de marcs òptics. D'altra banda, amb l'objectiu d'aconseguir la màxima simplificació en els processos de maneig de la informació, el sistema oferix múltiples vies d'introducció de nous continguts, oferint formes i mètodes que permeten la digitalització de la informació d'una forma senzilla i natural, establint una relació senzilla i transparent entre el món real i el virtual, contribuint d'esta manera a la generació dels Espais de Realitat Mesclada. En la mateixa línia, seguint una estratègia BYOD ("Bring Your Own Device") , el sistema permet la utilització de qualsevol dispositiu smartphone, o semblant, per a l'addició de nova informació. Finalment, un aspecte destacable de la tesi ha consistit en l'avaluació de forma rigorosa dels anteriors sistemes sobre nombrosos contextos educatius reals, des del punt de vista de tres paràmetres: eficiència, motivació i usabilidad.

Full textAquesta tesi doctoral sorgeix davant la necessitat creixent per part de la majoria d'em-preses, i especialment (però no únicament) d'aquelles dins dels sectors farmacèutic, químic, alimentari i de bioprocessos, d'augmentar la flexibilitat en el seu rang operatiu per tal de reduir els costos de fabricació, mantenint o millorant la qualitat del producte final obtingut. La tesi se centra en l'aplicació dels conceptes del Quality by Design per a l'aplicació i extensió de diferents metodologies ja existents i el desenvolupament de nous algorismes que permeten la implementació d'eines adequades per al disseny d'ex-periments, l'anàlisi multivariada de dades i l'optimització de processos en l'àmbit del disseny de mescles, però sense limitar-se exclusivament a aquest tipus de problemes. Part I- Prefaci, en què es presenta un resum del treball de recerca realitzat i els objec-tius principals que pretén abordar i la seua justificació, així com una introducció als conceptes més importants relatius als temes tractats en parts posteriors de la tesi, com ara el disseny d'experiments o diverses eines estadístiques d'anàlisi multivariada. Part II - Optimització en el disseny de mescles, on es duu a terme una recapitulació de les diverses eines existents per al disseny d'experiments i anàlisi de dades per mit-jans tradicionals relatius al disseny de mescles, així com d'algunes eines basades en variables latents, tals com la Regressió en Mínims Quadrats Parcials (PLS). En aquesta part de la tesi també es proposa una extensió del PLS basada en kernels per a l'anàlisi de dades de dissenys de mescles, i es fa una comparativa de les diferents metodologies presentades. Finalment, s'inclou una breu presentació del programari MiDAs, que ofe-reix la possibilitat als usuaris de comparar de forma senzilla diverses metodologies per al disseny d'experiments i l'anàlisi de dades per a problemes de mescles. Part III- Espai de disseny i optimització a través de l'espai latent, on s'aborda el problema fonamental dins de la filosofia del Quality by Design associat a la definició de l'anomenat 'espai de disseny', que comprendria tot el conjunt de possibles combina-cions de condicions de procés, matèries primeres, etc. que garanteixen l'obtenció d'un producte amb la qualitat desitjada. En aquesta part també es tracta el problema de la definició del problema d'optimització com a eina per a la millora de la qualitat, però també per a l'exploració i flexibilització dels processos productius, amb l'objecte de definir un procediment eficient i robust d'optimització que s'adapti als diversos pro-blemes que exigeixen recórrer a aquesta optimització. Part IV- Epíleg, on es presenten les conclusions finals i la consecució d'objectius i es plantegen possibles línies futures de recerca arran dels resultats de la tesi. En aquesta part s'inclouen a més els annexos.
The present Ph.D. thesis is motivated by the growing need in most companies, and specially (but not solely) those in the pharmaceutical, chemical, food and bioprocess fields, to increase the flexibility in their operating conditions in order to reduce production costs while maintaining or even improving the quality of their products. To this end, this thesis focuses on the application of the concepts of the Quality by Design for the exploitation and development of already existing methodologies, and the development of new algorithms aimed at the proper implementation of tools for the design of experiments, multivariate data analysis and process optimization, specially (but not only) in the context of mixture design. Part I - Preface, where a summary of the research work done, the main goals it aimed at and their justification, are presented. Some of the most relevant concepts related to the developed work in subsequent chapters are also introduced, such as those regarding design of experiments or latent variable-based multivariate data analysis techniques. Part II - Mixture design optimization, in which a review of existing mixture design tools for the design of experiments and data analysis via traditional approaches, as well as some latent variable-based techniques, such as Partial Least Squares (PLS), is provided. A kernel-based extension of PLS for mixture design data analysis is also proposed, and the different available methods are compared to each other. Finally, a brief presentation of the software MiDAs is done. MiDAs has been developed in order to provide users with a tool to easily approach mixture design problems for the construction of Designs of Experiments and data analysis with different methods and compare them. Part III - Design Space and optimization through the latent space, where one of the fundamental issues within the Quality by Design philosophy, the definition of the so-called 'design space' (i.e. the subspace comprised by all possible combinations of process operating conditions, raw materials, etc. that guarantee obtaining a product meeting a required quality standard), is addressed. The problem of properly defining the optimization problem is also tackled, not only as a tool for quality improvement but also when it is to be used for exploration of process flexibilisation purposes, in order to establish an efficient and robust optimization method in accordance with the nature of the different problems that may require such optimization to be resorted to. Part IV - Epilogue, where final conclusions are drawn, future perspectives suggested, and annexes are included.

Full textThe present investigation was elaborated with the purpose of studying the influence of the addition of rice husk ash (RHA) and polypropylene fibers (PPF) on the plastic shrinkage cracking of concrete. The research study took place in the city of Lima, where we focused on investigating the plastic and mechanical properties of a concrete f´c = 210 kg / cm2, which is commonly used in the manufacture of solid slabs, with partial replacement of the cement by RHA in percentages of 5%, 10% and 15% respect to its weight and PPF in yield of 900 g / m3. The main properties in the hardened state were investigated, the compressive strength and flexural strength and the property in the plastic state that developed was cracking due to plastic shrinkage through the ASTM C1579 test. Taking into account that there is no agreement regarding the maximum width in a structural element, it was decided to use limits between 0.2 to 0.4 mm, for normal environments, suggested by Mg. Eng. Gianfranco Ottazzi. According to the results obtained, the mixture added with RHA in replacement of cement in percentages of 5%, 10% and 15% together with PPF in yield of 900 gr / m3, we can infer that the RHA will reduce, not significantly, the strength properties of a concrete f´c = 210 kg / cm2, however, reduce the average occurrence of cracks produced in solid slabs due to the plastic shrinkage of the same.

Full text[EN] This thesis research the supply logistics in an automobile assembly lines, which ranges from the arrival of the material to the reception docks until its subsequent consumption in the assembly line, from an efficiency and safety point of view. In the current factories, the amount of references to manage due to the greater customization of the final product, increases the complexity of the logistics management in the factories. Tens of miles of material deliveries to the final assembly line have an impact in in-plant efficiency, safety and traffic, where their management becomes very important during the supply and its design designs. This thesis proposes a methodology for evaluating the safety and traffic of the material flow during the material supply in multi-model assembly plants. This methodology consists of several stages and includes quantitative evaluation tools, such as optimization and discrete evento simulation and qualitative events, through an audit questionnaire proposal. The proposed methodology arises from the review of the literature on internal logistics, safety and traffic in-plant, and then is validated and improved iteratively through its application in three real case studies in different european assembly plants.
[CA] Aquesta tesi investiga la logística d'aprovisionament en una llínia de muntatge d'automòbils, que abasta des de l'arribada de l'material als molls fins al seu consum posterior en la llínia de muntatge, des d'un punt de vista d'eficiència i també de seguretat. A les fàbriques actuals, on la quantitat de referències a gestionar a causa de la creixent personalització del producte final, augmenta la complexitat de gestió en les fàbriques. Les desenes de millers d'enviaments de material a la llínia de muntatge provoquen que l'eficiència, la seguretat i la gestió de l'trànsit passen a ser de vital importància durant la gestió i el disseny dels sistemes de subministrament. En aquesta tesi es proposa una metodologia d'avaluació de la seguretat i el tràfic del flux de material durant el subministrament de material en plantes de muntatge multimodel. Aquesta metodologia consta de diverses etapes i inclou eines d'avaluació quantitativa, com és l'optimització i la simulació per events discrets i també qualitativa, a través d'una proposta de qüestionari d'auditoria. La metodologia proposada sorgeix de la revisió de la literatura sobre la logística interna, la seguretat i el trànsit a la planta, i es valida i millora iterativament a través de la seua aplicació en tres casos d'estudi real en diferents plantes de muntatge europeu.
