Hablar de urbanismo contemporáneo es entender la actual ciudad latinoamericana, es decir, comprender que el fenómeno de ocupación de la ciudad está expuesto a un sinnúmero de externalidades y que el impacto sobre los bordes y las áreas suburbanas solo ha dejado marginalidad, segregación y altos índices de precariedad social, ambiental y humana. Alcanzar el desarrollo sostenible como el “deber ser” para el territorio nos demanda un estudio consiente con el fin de encontrar estrategias que permitan la implementación y alcanzar metas para ciudades más prosperas para el año 2030. A partir de la deducción “practica” del urbanismo como disciplina, se han logrado identificar cuatro indicadores relevantes que permiten hablar de desarrollo sostenible desde una visión más social, con ideas de valor, dentro de un marco de fortalecimiento comunitario, y superando el grado de fragmentación que constantemente muestra la ciudad en su periferia. La prosperidad, la inclusión, la apropiación y la adaptación han sido definidas como índices alternativos para medir la sostenibilidad del territorio y la capacidad de innovación en pro del crecimiento y el desarrollo social y urbano. Al final se encuentra un instrumento que permite cuantificar con más profundidad el impacto que los asentamientos de borde tienen sobre las áreas suburbanas para así planificar la ciudad desde un modelo prospectivo.

Los Arenales大营地是一个聚集区，到2022年，它已经聚集了2000多个家庭，其中大多数是定居在安托法加斯塔市北部地区的移民。这一复杂的领土实体已成为其社区组织在争取住房权的斗争中所强调的国际城市空间，尽管存在复杂性。这篇文章解释了洛斯阿雷纳莱斯社区领导人的讲话，以帮助了解形成高度复杂的非正式定居点的过程和意义。因此，这篇文章有助于从处境不稳定的社区重新思考智利的住房政策。成功地确定了生境的创造性社会生产能力，这可能是一项住房政策的基础，该政策的重点是向社区提供资源，使社区能够在技术援助下合作生产自己的空间。

Esta investigación busca verificar la huella de carbono (HC) en envolvente térmica de los cerramientos para proyectos de rehabilitación en infraestructura educacional, utilizando el análisis de ciclo de vida (ACV). El análisis comparativo de los casos se enfoca en materiales aislantes de origen vegetal, mineral y sintético. Los resultados indican que los valores de HC en soluciones comparadas disminuyen solo ahí donde se utiliza aislante térmico local, como el caso de celulosa proyectada y poliestireno expandido (EPS). Las soluciones con aislantes importados de HC negativa en la fase de extracción-fabricación (como losa de corcho o lana de roca), aumentan su huella en la fase de construcción hasta en tres veces respecto de soluciones locales debido a la incidencia del transporte. Se concluye que el impacto del transporte en la construcción de envolventes aumenta considerablemente las emisiones de CO2 en el ciclo de vida del proyecto, siendo los aislantes locales la solución más sustentable.

Shifting the mobility paradigm from fossil fuel to electric propulsion system poses several challenges to a large extent attributed to the low energy density of storage systems. However, technology improvements and an accurate combination of new propulsion systems can facilitate the electrification of the mobility sector. For the first time, a hybridization algorithm is developed to evaluate the optimal configuration of future Energy Storage System (ESS) to facilitate the design of systems such as aircrafts or ships. The algorithm is based on operational behaviors and high-level performances to determine the optimal solution through a standard random search of the input variables. To feed the algorithm, forecasts including estimated performances are carried out on new energy storage technologies such as Fuel Cells (FCs), batteries, and hydrogen storage. The hybridization algorithm is then applied to the design of a 50 passengers' regional electric aircraft in 2040. The results suggest that the best ESS includes a Solid-State Battery (SSB) of 457 kWh, a 1788 $mathbf{kW}$ Solid-Oxide Fuel Cell (SOFC) plant and consumes 190.9 kg of hydrogen. This configuration appears to be the optimal trade-off to minimize weight, volume, and costs.

The paper describes the constitution of the Engineering Research Center for the Aerial Mobility of the Future (ERC-AMF) having ITA as the host institution, Embraer as the industrial partner, and researchers from the University of São Paulo and the University of Campinas. The objective of the ERC-AMF is the realization of R&D to contribute to overcoming challenges to the shaping of aerial mobility in the upcoming decades. These challenges arise from the necessity of reducing pollutant and noise emissions, and the need for increased efficiency of manufacturing processes, besides the trend of introducing in the market novel aircraft adapted for operation in urban environments and short-range travels. Five research areas are focused on the first operation phase of the Center: Machine Control for Electric Propulsion; Aeropropulsion Integration in Electric Aircraft; Methods for Decision Making in Autonomous Systems; Advanced Design for Metallic Additive Manufacturing; and Intelligent Aircraft Final Assembly. Each line will be developed by researchers from partner universities and engineers from Embraer. It is expected that the Center will contribute to the appropriation, by the Brazilian aeronautical industry, of scientific and technological knowledge generated, and, as a result, increase its preparedness to face challenges that shall be overcome in the process of shaping the aerial mobility of the upcoming decades.

This paper presents a fully analytical procedure for the computation of the no-load characteristic of salient-pole wound field synchronous machines. The proposed method consists of applying the Ampere's law to the magnetic circuit along the d-axis divided into five different parts. The procedure considers the magnetic shunt of the stator slots and the distortion of the air gap flux density caused by the lamination saturation. Moreover, the waveform of the air gap flux density also takes into account the anisotropic shape of the rotor pole. The procedure has been validated by means of finite elements simulations on two different machines.

Current climate change policies require the reduction of both greenhouse gas and pollutant emissions of the marine sector. To achieve such a goal, the use of non-fossil fuels is one of the proposed solutions. Specifically, methanol has several advantages in respect to other fuels (both fossil and non-fossil), providing a feasible near-term solution for a more sustainable maritime transport. However, since methanol presents different characteristics in respect to actual fossil fuels, it is required to carefully evaluate the effect of its onboard integration on a ship to determine both the technical and economic feasibility of transitioning the onboard power production to such a fuel. The study presented in this paper analyzes the consequences deriving from equipping a modern all electric expedition cruise ship with methanol fuel, considering both technical and economic aspects.

This paper presents a closed form analytical model for semiconductor and capacitor currents in a 5-Level Active Neutral Point Clamped Converter (5L-ANPC) topology. This model enables device selection, performance prediction, and design optimization of the topology. Models for the switch and FC currents are derived based on the topology's switching states. A model for input capacitor current is derived by analyzing the interaction of three phase legs of the topology. The model is verified using conventional time-domain switching simulation of the topology.

The motivation of this work is given by the search for alternative solutions for the energy supply in aerial platforms, in a way that they are based on clean fuels and do not throw polluting emissions into the atmosphere. In this way, a hybrid electrical propulsion system has been designed, consisting of a polymer electrolyte membrane fuel cell (PEMFC) and a LiPo-type battery pack. The hydrogen-based propulsion system meets the take off and flight requirements of the aerial platform, improving the characteristics provided by previous versions. Therefore, the inclusion of hydrogen technology in the aeronautical field, despite presenting certain difficulties, arises as a viable solution with a long-term path, thanks to not only eliminate the fossil fuels dependence but also to increase endurance, reduce noise footprint and eliminate polluting emissions throw into the atmosphere.

Electrification significantly increases the complexity of aerospace electric power systems (EPS), as there is a transition from conventional aircraft to more electric aircraft (MEA) and all electric aircraft (AEA) [1]. This publication shows a novel method to use Power Hardware-in-the-Loop (PHIL) based inverter emulator (PHIL-IE) as an efficient test tool along the product life cycle. In early R&D phase the PHIL-IE can already fully emulate the future target inverter with full power under real life conditions. The same PHIL-IE with a modified HIL model can be used to test the target inverter. Finally, the PHIL-IE with a more complex HIL model can function as test unit to emulate batteries, H2-Systems, machines and more within an iron bird. In addition, this method is perfectly suitable for co-simulations of real electric components and digital twins.
