Human pose completion in partial body camera shots
Full text linkMany actual images contain partial body camera shots, in which a significant part of the body is not visible. This issue is especially prevalent in film images, where less than 10% are full-body shots. Most 2D human pose estimation methods return incomplete poses when applied to partial body images. This lack of completeness becomes a problem in some situations, for example, when the 2D pose is converted to a 3D pose by a two-stage 3D human pose estimation method since most of these methods require a complete pose to work. This article proposes a new technique, called CompletePose, consisting of completing the missing keypoints when 2D human pose estimation methods are applied to images with partial body camera shots. A Conditional Generative Adversarial Network is used to obtain a complete and plausible pose, realistic enough to predict a 3D pose with a two-stage 3D human pose estimation method. A complete empirical validation has been carried out with the Human3.6 M dataset and a new dataset, called CHARADE, specially built and made public for reproducibility and benchmarking for this research. Quantitative evaluation employing the Fréchet distance shows that the approach manages to approximate the actual data distribution. The qualitative evaluation shows that the completed poses enable obtaining plausible 3D poses from images previously intractable.This work is partially supported by the Spanish Ministry of Science and Innovation under contracts PID2019-107255GB, PLEC2021-007850 and RTI2018-095232-B-C21, and by the SGR programme of the Catalan Government under contracts 2021-SGR00478, 2017-SGR-1414 and 2017-SGR-1742.Peer ReviewedPostprint (author's final draft

Addressing the compositional character of international humanitarian aid delivery in humanitarian hubs: Case applied to CLRAH
Full text linkThe Regional Logistics Centre for Humanitarian Assistance (CLRAH, for its acronym in Spanish), located in Panama, is the first humanitarian hub dedicated to delivering international humanitarian aid to Latin America and the Caribbean (LAC). This study analyses the trends in the delivery of humanitarian assistance from CLRAH between 2017 and 2021. A distinguishing feature of humanitarian aid delivery is the compositional nature of its indicators, which corresponds to the multidimensionality of the strategies adopted to ensure the timely delivery of aid. Within this framework, additive log-ratio, centered log-ratio, and isometric log-ratio transformations were used to assess humanitarian aid delivery from a compositional approach. The findings highlight the growing importance of health supplies and shelter in recent years, as well as the role of air and maritime transport in facilitating humanitarian aid delivery. Cuba, Venezuela, and Haiti stand out among the most aided countries over the analysed period. Additionally, insecurity and corruption were identified as two social problems in recipient countries that should be taken into account in the delivery of humanitarian aid from the CLRAH to LAC. Compositional Data Analysis proves more effective in managing the compositional indicators of CLRAH humanitarian aid delivery than traditional raw data modeling techniques. To the best of our knowledge, this is the first study to address the importance of managing indicators in a humanitarian centre using the Compositional Data Analysis approachThis work was supported by the Ibero-American Programme of Science and Technology for Development (CYTED), through the Network for the Construction and Evaluation of Innovative Capacities in the Academic Sector (CECIAC)Postprint (published version
D4.2 Operational guide for maintaining good indoor air quality and thermal comfort with natural ventilation in educational buildings
No full textThis document presents the natural ventilation operational guide for educational buildings developed by the IAQ4EDU project. Most educational buildings are completely naturally ventilated. This challenges the indoor environmental quality management of schools in terms of balancing the needs of students for indoor air quality and thermal comfort. This guide presents the conditions and methods of using natural ventilation strategies to maintain good air quality and thermal comfort in classrooms. Using the example of Catalonia (Spain), a general ventilation protocol was developed to guide teachers in implementing natural ventilation in different seasons to ensure air quality during school hours. Relevant users can refer to the case in this practical guide to develop ventilation protocols based on the local climate and school conditions.Objectius de Desenvolupament Sostenible::7 - Energia Assequible i No ContaminantObjectius de Desenvolupament Sostenible::3 - Salut i BenestarPreprin

Integració dels ODS 2030 al CFGS projectes d'edificació: un enfocament des dels 5 vectors de sostenibilitat
No full textA partir d'una anàlisi del paradigma del Desenvolupament Sostenible i dels ODS 2030 a nivell global, es proposa la integració dels ODS al currículum previ del CFGS Projectes d'Edificació a l'àmbit legislatiu de l'educació a Catalunya. Primer, es fa una anàlisi de la relació entre els diferents ODS i els objectius pedagògics del Cicle, per tal de fer una proposta de Currículum que hi inclogui els ODS. Després, es fa una proposta de programació i continguts per al nou Mòdul de Sostenibilitat en base als objectius pedagògics que dicta el Real Decreto 659/2023. Per aquest mòdul es proposa un contingut holístic i específic al Cicle, amb continguts disciplinars i profesionalitzadors. Es proposa la formació disciplinar dels alumnes en els 5 Vectors Ambientals, en les 5 Estratègies i en els Indicadors Ambientals. La metodologia pedagògica del Mòdul es basa en una progressió des de las classes inicials més teòriques cap a metodologies que afavoreixin l'Aprenentatge Significatiu, des de l'evocació fins les metodologies ABP. Per últim, es proposa una Activitat Final d'Ensenyament i Aprenentatge Basada en Projectes on els alumnes han de desenvolupar un Projecte d'Edificació i un Producte o Servei, que a més han d'esser capaços d'avaluar utilitzant els Indicadors Ambiental

Més enllà de les cartografies operatives
No full textQuè fa operatius el diagrama i la cartografia? Com representar una ciutat governada per lleis invisibles? On acaba la cartografia i comença el diagrama?
“Més enllà de les cartografies operatives” busca donar resposta o reflexionar, si més no, sobre aquestes tres preguntes. Aquest Treball de Fi de Grau aborda de manera paral·lela l’estudi de les cartografies i els diagrames com a eines operatives en l’arquitectura i l’urbanisme. A partir d’aquestes dues línies d’investigació, es busca entendre el funcionament d’aquests sistemes de representació amb l’objectiu de dur a terme una reavaluació crítica en el context del món contemporani.
En una primera fase conjunta, s’analitza la notació com a tècnica representativa tant en la cartografia com en el diagrama. Seguidament, el TFG es bifurca en dos camins paral·lels, que analitzen de manera específica la cartografia i el diagrama i les seves respectives reavaluacions, reflexionant sobre les transformacions que s’estan produint en l’àmbit de la representació arquitectònica, derivades dels canvis digitals i socials que caracteritzen el món contemporani. Finalment, aquests dos camins acaben confluint en un punt comú, el que rep el nom de cartografies conceptuals o diagrames cartogràfics. En aquest apartat final, es fa una breu reflexió sobre les cartografies conceptuals o diagrames cartogràfics i es presenta una selecció de nou exemples que es consideren pertinents i aplicables en el context contemporani

The peaceful and quiet neighbourhood of Mistrzejowice is surrounded by greenery. Becoming a welcoming place to retire. This greenery was a key point during the design of the place. All the people living here are aware of the wealth of these surroundings that are now threatened by the increase in car use and the need for parking places. They are coming together to defend it and ensure it remains as it is now.
