    Thesis abstract: This thesis aims to investigate the efficacy and applicability of Wireless Backhaul Network (WBN) in two divergent contexts: ultra-dense urban networks for 5G and connectivity solutions for rural or digitally divided areas. WBN offer an adaptable and resilient framework for data transmission, making them an attractive option for the next generation of wireless networks, particularly 5G. In dense urban settings, where the demand for high data rates is pressing, wireless mesh backhauls can serve as a strategic asset in achieving the promised data throughput for 5G networks. These networks inherently require a dense deployment of nodes to deliver on their promise of high-speed, low-latency communication. Therefore, we analyze the role that wireless mesh backhauls can play in such densely populated areas, emphasizing their potential to meet or even exceed 5G¿s high data rate expectations.Conversely, in rural or digitally divided areas, the economic feasibility of deploying traditional last-mile copper or fiber-optic networks often proves to be prohibitive. In such cases, WBN, deployed either as Wireless Community Network (WCN) or as part of a Wireless Internet Service Provider (WISP)¿s infrastructure, can offer a viable alternative. This technology could bridge the digital divide by providing robust, cost-effective internet connectivity to underserved regions.To substantiate my findings, I leveraged Geographic Information Systems (GIS) technology and GPU-based computational methods together with graph analysis and simulations. GIS technology, leveraging different open datasets such as Digital Surface Models (DSM) and vectorial maps, make a detailed understanding of the geographical landscape possible, crucial for building detailed feasibility models in various environments. GPU-based computational methods accelerate the model analysis, enabling an in-depth evaluation within a reasonable timeframe. As a result I was able to optimize various network aspects, such as node placement, network topology and energy consumption, which are critical parameters for the effective deployment of these networks.This work integrates these computational methods and technologies to offer a comprehensive view of how wireless mesh backhauls can be efficiently deployed in both urban and rural settings. The results offer valuable insights into the network architecture best suited for each context, with particular attention to scalability and resiliency. In summary, this thesis contributes to a broader understanding of the potential that wireless mesh backhauls hold in addressing the connectivity requirements of diverse settings, ranging from the ultra-dense urban environment required for 5G to the unique challenges posed by rural and digitally divided regions.

    Thesis abstract: This doctoral thesis examines the process of adaptation of Modern Architecture in Quito over a period of twenty years (1960-1980). The city's location at latitude 0 and an elevation of 2850 meters above sea level determines the unique solar light that influences both the natural and artificial contexts.There are no studies on light under these conditions, nor one that compiles the most important references for those interested in architecture in Quito, especially students. Another motivation is to highlight the efforts of the most influential generation of architects in the country, unknown to most young people, an aspect that this work seeks to address.The methodology includes an extensive bibliographic source, field visits, interviews, and photographic resources, as well as the redrawing of all the projects (38) to establish a common basis for analysis using current technical visualization and modeling resources.The study begins with a description of the Andean mountains in general, the Andes in Ecuador, and concludes with the Guayllabamba Basin, where the city of Quito is located, along with its volcano, Pichincha. This first part is complemented by the research of Alexander von Humboldt, who in the 19th century led an expedition to study the flora and fauna of various Latin American countries, including Ecuador.The second part of the thesis presents the city of Quito in three moments: the pre-Columbian city, the colonial city, and the modern city.In the third part, the influence of Humboldt on landscape painting is revisited, followed by landscaping in Ecuador and painting in the mid-20th century. Painting, along with photography and watercolor, contributes to understanding the light of Quito, as well as the particular descriptions of it in literature.The following section organizes specific aspects of light in terms of principles, spaces, and relevant lighting elements in the urban environment of Quito.In the fourth section, the process of learning and adaptation of modern architecture in Quito is addressed.The analysis of three selected works for their relationship with the landscape reveals the value of the study. As a complement and context to these works, the systematic analysis of 38 works considered in this work is presented, serving as a very useful reference.In conclusion, this doctoral thesis highlights the importance of a comprehensive approach in architecture, focused on light and the environment. The findings of this work provide valuable information for architecture in harmony with Quito's environment, promoting identity and suggesting possible directions for future research.

    Thesis abstract: This doctoral thesis aims to develop an Additive Manufacturing technique for the production of Ceramic Building Elements with controlled variable density. The research seeks to provide an alternative to the currently available building elements in the construction industry, focusing on the design of construction elements with specific characteristics through the manipulation of porosity.The hypothesis suggests that Additive Manufacturing technologies can be used to produce ceramic materials with controlled variable density, which could replace conventional systems composed of ceramics and complementary layers of different materials. Unlike other works, this proposal allows for the establishment of pore size and connectivity.The work methodology is divided into two complementary parts. On one hand, it focuses on developing the manufacturing means, including hardware and software, while on the other hand, it studies the resulting product, namely, the printed ceramics with variable density. A research, design, and construction process are carried out, which includes different steps such as studying the state of the art in additive manufacturing and materials with gradient function, selecting and constructing a 3D printer, developing a clay extrusion system adapted to the machine, calibrating the manufacturing process, defining porosity limits, creating design strategies, and manufacturing demonstration pieces.The results of this research will have broader implications in the field of architecture and construction. The additive manufacturing technique with controlled variable density will enable the creation of mono-material systems with improved properties, opening new possibilities in the design and construction of building elements. Furthermore, the use of a single constituent material with density variations can contribute to optimizing the management of construction waste and reducing the environmental impact of the industry. This research can also drive the advancement of additive manufacturing in producing materials with gradient function in various sectors, including aerospace and materials engineering.In summary, this doctoral thesis aims to develop an Additive Manufacturing technique for producing Ceramic Building Elements with controlled variable density. The methodology is based on research, design, and construction of manufacturing means, as well as the study of the resulting product. The results of this research will have implications in the design and construction of building elements, as well as in the advancement of additive manufacturing in other industrial sectors.

    Thesis abstract: The main objective of this thesis is to develop and validate simple but sufficiently accurate mathematical models for single-phase and three-phase transformers, by estimating their parameters from simple laboratory tests and field measurements, in particular, from the information obtained from the inrush current. The energizing process of a transformer results in the generation of a high inrush current due to the saturation of the transformer core. This current can cause several problems, such as protections tripping and consequently being out of service. Clearing faults in the transmission network can also lead to transformer saturation. A part of this work aims to develop methodologies for the reduction of these high inrush currents.In the literature, a great effort has been dedicated to the modeling, identification and analysis of electrical transformers. The representation of a transformer can be very complex due to the different types of core configurations and the large number of transformer parameters, as well as the fact that some of these parameters are nonlinear and even frequency dependent. These include core and coil configurations, self and mutual inductances among coils, dispersion fluxes, skin and proximity effects in coils, magnetic core saturation, hysteresis cycles, losses due to eddy currents, and capacitive effects.The materials commonly used in transformer cores, like ferromagnetic materials, exhibit non-linear magnetic permeability, and usually work slightly saturated. The behavior of a non-linear core is given by the relationship between the magnetic field and magnetic induction, known as the magnetization or saturation curve. There are different ways to model the nonlinear operation of a magnetic core, ranging from finite elements to single-valued functions, through especially complex models such as Jiles-Atherton or Preisach hysteretic models.This work is focused on low frequencies models (up to a few kHz), whose parameters reproduce in detail those situations in which the nonlinearity of the magnetic circuit significantly influences its dynamic behavior. For example, inrush current can be predicted, for which modeling or estimation of the residual flux is necessary. The adjustment of the parameters will be based on experimental measurements to which the developed adjustment algorithms will be applied. These measurements will be obtained both in specific laboratory tests and in transient connection records in transformers connected to the distribution network.Although articles on transformers have been published for more than seventy years, the high number of current publications on their modeling and on the problems derived from their non-linear behavior is an indication that the issue has not been resolved satisfactorily and which is still relevant.

    Thesis abstract: The subject of the thesis focuses on landscape, including how it relates to gardens, architecture, the environment, and how different areas are used over space and time. Natural spaces have a high potential to be developed in the new smart cities, and the fusion of the physical environment and digital information is undergoing a fundamental transition. In this, the composition of the landscape can open the way to the renewal of culture, a characteristic searched in the Victorian era and slightly forgotten after the First World War. The characteristics to be considered in green areas planning to maximize the rising of culture can include the use of the same along the various hours of day and night. In this research, the hypothesis is that parks are positively correlated with the establishment of social activities, and provide the opportunity for promoting the release of stress in a behavioral setting. The implication of this study may assist urban and landscape designers, planners, and architects in creating a sociable green environment. After reviewing existing literature in this field and identifying a scientific gap, a set of theoretical frameworks was conducted to facilitate the grasp of notions developed in this study. Afterward, by describing of implemented methods, the process of applying different procedures was explained, including questionnaires and interviews with key figures in the field. Subsequently, the obtained findings were presented and discussion and conclusions were presented, joined with a simulation project presented within the annexes, to visually express the high potentiality discovered with the research. All this, therefore, can be the basis for further research oriented towards a new type of ecological design. The goal is to guide knowledge and innovation in green design through the use of new technologies, going beyond the process of traditional design production. In envisioning the future of urban parks, the study proposes a transformative direction, advocating for parks to evolve beyond recreational spaces into vital hubs for education, culture, sustainability, and technological innovation. The research, conducted in newly built parks in Barcelona compared to Vancouver's model, offers insights into potential new uses for these spaces. Acknowledging its geographical and historical limitations, the study emphasizes its relevance to contemporary parks, highlighting the need for specific studies to explore how modern technologies can be integrated into historic parks: without compromising their heritage value.
