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.","PeriodicalId":38493,"journal":{"name":"AUS","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47199286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El presente artículo elabora una interpretación de los discursos de las lideresas comunitarias de Los Arenales para contribuir a informar los procesos y los significados detrás de la formación de un asentamiento informal de alta complejidad. Con ello, el artículo ayuda a repensar la política habitacional en Chile desde las comunidades en situación precaria.

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.","PeriodicalId":38493,"journal":{"name":"AUS","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43348914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"4 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74295562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"208 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78248648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"17 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89140406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
