Deep learning methods are widely used in the domain of change de- tection in remote sensing images. While datasets of that kind are abundant, anno- tated images, specific for the task at hand, are still scarce. Neural networks trained with Self supervised learning aim to harness large volumes of unlabeled satellite high resolution images to help in finding better solutions for the change detection problem. In this paper we experiment with this approach by presenting 4 dif- ferent change detection methodologies. We propose a fusion method that under specific parameters can provide better results. We evaluate our results using two openly available datasets with Sentinel-2 satellite images, S2MTCP and OSCD, and we investigate the impact of using 2 different Sentinel 2 band combinations on our final predictions. Finally we conclude by summarizing the benefits of this approach as well as we propose future areas of interest that could be of value in enhancing the change detection task’s outcomes. Keywords: Change Detection · Self Supervised Learning · Satellite images 1 Introduction The history of change detection can be traced back to the early days of remote sensing with one of the first examples being the use of aerial photography to identify agricul- tural land use changes [13]. Change detection is the process of comparing two images of the same area at different times to identify changes, such as urban growth and de- velopment, deforestation events and vegetation evolution. Those changes are depicted onto a change mask where usually a white pixel represents a change and a black pixel that nothing has changed. Despite the large amount of data that is now available from programs like Coperni- cus and Landsat, there is still a lack of open labelled datasets using these images. This makes it difficult to compare and evaluate new proposed change detection algorithms. Sufficient labelled datasets are essential for developing supervised learning methods with deep neural networks. A promising candidate in tackling this problem is Self Supervised Learning(SSL), a subset of Unsupervised Learning. The term supervision means that labels do exist

ABSTRACT • We present an update of the MulChem chemical evolution model applied to the Milky Way Galaxy, by using the most recent stellar yields for low and intermediate mass stars and for massive stars. • We study the role of the different type Ia supernova (SN Ia) rate prescriptions, using 15 different Delay Time Distribution (DTD) functions, depending on the binary stars able to create a SN Ia scenario • Simultaneously, 12 tables of yields of elements produced by different explosion mechanisms for SN-Ia are explored. The chemical abundances derived from these 180 models, resulting from the combination of different set of SN Ia yields and DTDs, are analized. • The results of the Solar Region for [Fe/H] and [a/Fe] vs. Stellar age and for [a/Fe] vs. [Fe/H] (where a-elements are O, Mg, Si, S, and Ca) are compared with an extensive observational dataset coming from the most recent surveys and compiled for this work. • Then, the best model able to reproduce the observational data is selected by means of a c2 technique. • We analyse the results obtained for relative abundance of a-elements (O, Mg, Si, S, Ca) with Fe as a function of the galactocentric distance and stellar ages for the disc and the halo. • In agreement with previous works, we find that a significant fraction of type Ia SNe must take place at short delay times in order to reproduce these observed abundance ratios [α/Fe], as a function of both stellar age and Fe abundance • The large dispersion of data could be explained by a mix of stars located at different spatial regions or that moved after their birth. A mix of different DTD’s or explosión mechanims may also justify part of this dispersion SUPERNOVA RATES AND [a/Fe] ABUNDANCES IN MWG: THEIR VARIATIONS IN TIME AND SPACE M.Mollá1, O.Cavichia2, J.J.Bazán1, A.Castrillo3, L.Galbany4,I.Millán-Irigoyen1 1CIEMAT, 2Univ.

1 The Ideation Capacity Guided by an Intercultural Experience During the Concept Designing Process, a Case Study Dirk van Gogh* Hiroko Yamazaki ** * Chairman of Design Study Group of KASK,-Royal Academy Fine Arts Ghent, Belgium, dirk.vangogh@hogent.be ** Homeopath, VGC association, Antwerp, Belgium, hiroko_ymzk@yahoo.co.jp Abstract: The present paper evaluates the concept designing process among Belgium students of the course ‘Product Development’ and the students of the course ‘Multimedia Design’. Examining 4 projects during the design workshop, named: “Inspired by Japanese Home Cooking”, we discuss how the ideation capacity was activated by intercultural experience. Key words: Culture, Ideation, Cooking 1. Introduction As one of the trainings to optimize students’ design capacity in an international context, the Higher Institute for Product Development, Design Sciences, University College of Antwerp holds a workshop-week in the year of 2009 under the theme of “Products and Services for Food and Drinks”. A similar workshop was held in the Royal Academy of Fine Arts, University College of Ghent during the course ‘Multimedia Design’ in May 2010. In this paper, a brief report is presented of one workshop, named “Inspired by Japanese Home Cooking” and run by, a Belgian doctor in product development Dirk van Gogh and a Japanese homeopath Hiroko Yamazaki. The main objectives of the workshop were: to activate students’ ideation capacity by giving inspirations from authentic Japanese home-style cooking and to make it possible for students to develop innovative products or eating environments based on Western and Asian cultural viewpoints. 2. Methods 2.1. Participants Twenty students participated, including 4 from first-year master course, 6 from third-year bachelor course, 5 from second-year bachelor course, and 5 from international students of the European Erasmus program. 2.2. Procedure The workshop especially focused on the following aspects: Introduction of Japanese home cooking: First of all, some key characters of Japanese home cooking were presented. One of the characters is its variety; that is, Japanese has introduced many other cultures’ cooking into their daily eating while respecting their own

An open-source solution for the implementation of scenario planning with an interactive visualisation tools Liam Webb1, Mitchel Langford1 and Gary Higgs1 GIS Research Centre, Wales Institute of Social and Economic Research and Data (WISERD), Faculty of Computing, Engineering and Science, University of South Wales, Pontypridd, CF37 1DL, UK December 12, 2022 *Liam.webb@southwales.ac.uk Summary KEYWORDS: Predictive analysis, API’s, Accessibility, PSS Summary This research will provide insight into scenario planning in GIS and how when mixed with interactive visualisation tools it can be used to provide unique insight into geospatial data and provide policymakers with more insightful data, which, in turn, can lead to better and more deliberated decisions. 1. Introduction Too often policymakers and decision-makers rely on outdated procedures and systems to undertake analyses and interrogation of spatial data, there is a danger in doing this that resources and results generated this way are not always as accurate when compared to current and modern techniques (Huang, et al., 2020). Despite this, there is scant evidence for the uptake of newer systems being created despite their increasing availability (Tsalamanis, 2018). By implementing multiple open- source techniques and technologies together, current visualisation tools have the potential to build in- depth analysis systems that provide a more portable and user-friendly approach that could increase uptake from policymakers and increase data effectiveness as a result. 1.1. AIMS AND OBJECTIVES  Implementation and investigation of scenario planning within GIS  Development and integration of visualisation tools and technologies  Creation of web-platform that allows users to have visualised results from scenario planning analysis The main goal of this research will be to investigate scenario planning and how it can be implemented within an accessibility tool that utilises visualisation tools and techniques to present temporal accessibility data through live calculations (not pre-stored data). With the creation of this tool policy makers could exploit data to predict what could happen if a certain scenario was carried out. 1.2. PREDICTIVE ANALYSIS AND PSS Planning support systems are systems that are created with the intent of providing planning data for specific tasks (Batty, 1995; Klosterman, 1997). By utilising temporal travel data as well as other supply-side variables predictive analysis within web-GIS can be used as a planning support system to assist policymakers in the planning of urban development. For example, by measuring the accessibility of supply-side variables such as banks and the effect that changing travel networks can
EUROPRO Digital Corpus Description The EUROPRO Digital Corpus is a collection of digital texts that reflect the discursive and linguistic practices of international research projects financed by the Horizon2020 European framework for excellence science and research innovation. As such, it is regarded as a specialized corpus of texts that is static, implying that it was compiled at one specific point in time. The EUROPRO Digital Corpus is divided into two sub-corpora focusing on specific objects of inquiry, namely the EUROPROwebs Corpus (European Project Websites) and the EUROPROtweets Corpus (European Project Twitter Accounts). Overall, the corpus allows us to analyse digital academic discourse and, through its analysis, insights can be gained into international research group’s evolving discursive and professional practices. Additionally, as the figure below displays, the EUROPRO Digital Corpus is part of a holistic network of genres, texts and documents that we have labelled as EUROPRO Repository and that go deeper into the academic, professional and contextual aspects that surround international research projects. Thus, this repository comprises the EUROPRO Database, which is an extension of the EUROPRO Digital Corpus and include a total of 100 Horizon2020 international research projects. Much as the EUROPRO Digital Corpus, two collections of texts make up this database: the EUROPROwebs Database containing 100 research project websites and the EUROPROtweets Database collecting the existing Twitter accounts derived from projects in the database. Lastly, the EUROPRO Repository has also a branch devoted to EUROPRO Documentation, where materials and resources are gathered to gain understanding into how international research projects are created and developed and how scientific knowledge is expected to be communicated, disseminated and exploited.
Promoting A Physical Security Mental Model For Personal Firewall Warnings Abstract We used an iterative process to design personal firewall warnings in which the functionality of a firewall is visualized based on a physical security mental model. We performed a study to determine the degree to which our proposed warnings are understandable for our participants, and the degree to which they convey the risks and encourage safe behavior as compared to warnings based on those from a popular personal firewall. Initial results show that our warnings facilitate the comprehension of warning information, better communicate risk, and increase the likelihood of safe behavior. Moreover, they provided participants with a better understanding of both the functionality of a personal firewall and the consequences of their actions.

— 707 711 Celebration & Contemplation, 10th International Conference on Design & Emotion 27 — 30 September 2016, Amsterdam Abstract In the Western world we tend to neglect our mental wellbeing. We ignore feelings of stress, anxiety or sadness until the point that these develop themselves into burnouts, depressions and other mental issues… ‘We never saw coming…’ After problems have escalated treatment is expensive, lengthy and bureaucratic. Treatment is also ‘disease’ oriented, reducing a person to a ‘patient’ and not focusing on possibilities. As much as one out of every four westerners may develop a mental issue during their lifetimes. In many of these cases, escalation towards severe mental illness can be prevented by a greater awareness and basic care of ones own mental health. Very much like we are supposed to keep our bodies fit, thereby preventing to become obese or heart diseased. Mindkeeper is a multidisciplinary collaborative design project that is doing just that: Psychologists, psychiatrics, patients, insurers, coders and designers have teamed-up to develop a digital tool that provides people agency regarding matters concerning their own mental health. Mindkeeper will do that by coaching the user in seeking emotional fulfillment on the basis of the users emotional state and context. This emotional state is monitored by Mindkeeper thus building a personal mental health record. The data making up this record is visualized in a coherent and pleasing way providing the user with an idea of what is going on in ones mind. This results in a clear and attractive overview of an area that is usually shrouded in mysteries and folklore. The user empowered with this mental insight, may use Mindkeeper to connect with a community. Once connected, people can post queries, receive answers, compare ones situation with selected others and receiving and reviewing tips and tricks in getting or keeping oneself on track. The basic idea is that Mindkeeper is aimed at relatively mental healthy people and that by using Mindkeeper, people remedy slight issues themselves, thereby staying in control and keeping the responsibility of their own mental well being in their own hands.

Page | 1 Using secondary data to examine whether a programme of interventions in urban forests enhances community health and wellbeing. Ogletree S*1, Ward Thompson C1, Clemens T1, Pearce J1, and Mitchell R2 1University of Edinburgh 2University of Glasgow GISRUK 2023 Summary There is a growing demand for better evidence on the importance of forests for human health, as this may be a key element of future forestry strategies. Combining data from the Scottish Census, Public Health Scotland, and Scottish Forestry this research sought to address specific questions about the impact of urban woodlands in deprived areas on mental health and child development. Spatial data on woodland interventions and residential location allowed for a unique level of analysis to investigate outcomes. KEYWORDS: Greenspace, Secondary data, Woodlands, Mental health 1. Introduction Globally, there is an increasing burden of non-communicable disease (NCD), particularly mental illness, which is experienced inequitably (with those poorest suffering most) and potentially affects all stages of life. For example, poor mental health in childhood has implications for health and wellbeing throughout life. In the short term, school attainment may be impaired (Trout et al., 2003) while, in the longer term, persistent mental health issues, higher mortality rates and wider inequalities may result (Dube et al., 2003, Jokela et al., 2009). More recently there have been substantial increases in the prevalence of childhood social, emotional, and behavioural problems (Layard and Dunn, 2009). To address this upward trend, and the consequent growing societal burden now and in the future, it is imperative to identify the determinants of these childhood problems as well as to address poor mental health in adults. At the same time, across the UK, Europe and beyond, there is a demand for better evidence on the importance of forests for human health, as this may be a key element of future forestry strategies (World Commission on Protected Areas, 2018, Marušáková et al., 2019). The climate emergency means tree planting is poised to expand in the UK and this offers an opportunity to establish and maintain forests that are productive and multifunctional, delivering ecosystem services while benefiting human health and wellbeing. In this context, those responsible for urban and peri-urban land management are asking: what does urban forestry mean for human use, social benefit and wellbeing in the context of health inequities? (Marušáková et al., 2019)? Scottish Forestry have identified an urgent need to understand the value of forests for health and wellbeing in order to target scarce resources most effectively. For the first time, we have an opportunity to link secondary data on mental health, child development and a decade-long national urban forest intervention programme to offer the kind of evidence being * scott.ogletree@ed.ac.uk
