The Future of The COSPAR Planetary Protection Guidelines: Space Governance and Astrobiology
The developing of questions of Outer Space has only been greatly enhanced by the increase of technology and greater involvement by states, private actors and people seeking to use space above the typical uses i.e., satellites. Such an approach has carried on the original views of space delivered by the Apollo programme, which has inspired entrepreneurs, scientists, politicians, and lawyers to challenge and develop hypothetical opinions and business strategy. Nevertheless, outer space is a free for all without jurisdiction. This thesis will consider both the future of space governance and the Committee on Space Research (COSPAR) planetary protection policy.
The uptake of scientific missions through the solar system has formed an enhanced interest as more than ever space exploration is pushing the boundaries are political and legal certainty. The Outer Space Treaty presents a number of fundamental and core elements within space and promotes cooperation through the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS). As such the future of space governance will be considered as to whether the current practice is âfit for purposeâ, or whether a new governance regime should be considered for the benefit of space cooperation. Moreover, appropriate discussions around the understanding of astrobiology and how such a road map sets out the need for a planetary protection resource during exploration of space will be examined in detail. COSPARs planetary protection policy will be examined in order to be able to justify whether there is any legal basis for such an implementation or whether the policy remains a recommendation

Seamless Multimodal Biometrics for Continuous Personalised Wellbeing Monitoring
Artificially intelligent perception is increasingly present in the lives of
every one of us. Vehicles are no exception, (...) In the near future, pattern
recognition will have an even stronger role in vehicles, as self-driving cars
will require automated ways to understand what is happening around (and within)
them and act accordingly. (...) This doctoral work focused on advancing
in-vehicle sensing through the research of novel computer vision and pattern
recognition methodologies for both biometrics and wellbeing monitoring. The
main focus has been on electrocardiogram (ECG) biometrics, a trait well-known
for its potential for seamless driver monitoring. Major efforts were devoted to
achieving improved performance in identification and identity verification in
off-the-person scenarios, well-known for increased noise and variability. Here,
end-to-end deep learning ECG biometric solutions were proposed and important
topics were addressed such as cross-database and long-term performance,
waveform relevance through explainability, and interlead conversion. Face
biometrics, a natural complement to the ECG in seamless unconstrained
scenarios, was also studied in this work. The open challenges of masked face
recognition and interpretability in biometrics were tackled in an effort to
evolve towards algorithms that are more transparent, trustworthy, and robust to
significant occlusions. Within the topic of wellbeing monitoring, improved
solutions to multimodal emotion recognition in groups of people and
activity/violence recognition in in-vehicle scenarios were proposed. At last,
we also proposed a novel way to learn template security within end-to-end
models, dismissing additional separate encryption processes, and a
self-supervised learning approach tailored to sequential data, in order to
ensure data security and optimal performance. (...)Comment: Doctoral thesis presented and approved on the 21st of December 2022

Anwendungen maschinellen Lernens fĂŒr datengetriebene PrĂ€vention auf Populationsebene
Healthcare costs are systematically rising, and current therapy-focused healthcare systems are not sustainable in the long run. While disease prevention is a viable instrument for reducing costs and suffering, it requires risk modeling to stratify populations, identify high- risk individuals and enable personalized interventions. In current clinical practice, however, systematic risk stratification is limited: on the one hand, for the vast majority of endpoints, no risk models exist. On the other hand, available models focus on predicting a single disease at a time, rendering predictor collection burdensome. At the same time, the den- sity of individual patient data is constantly increasing. Especially complex data modalities, such as -omics measurements or images, may contain systemic information on future health trajectories relevant for multiple endpoints simultaneously. However, to date, this data is inaccessible for risk modeling as no dedicated methods exist to extract clinically relevant information. This study built on recent advances in machine learning to investigate the ap- plicability of four distinct data modalities not yet leveraged for risk modeling in primary prevention. For each data modality, a neural network-based survival model was developed to extract predictive information, scrutinize performance gains over commonly collected covariates, and pinpoint potential clinical utility. Notably, the developed methodology was able to integrate polygenic risk scores for cardiovascular prevention, outperforming existing approaches and identifying benefiting subpopulations. Investigating NMR metabolomics, the developed methodology allowed the prediction of future disease onset for many common diseases at once, indicating potential applicability as a drop-in replacement for commonly collected covariates. Extending the methodology to phenome-wide risk modeling, elec- tronic health records were found to be a general source of predictive information with high systemic relevance for thousands of endpoints. Assessing retinal fundus photographs, the developed methodology identified diseases where retinal information most impacted health trajectories. In summary, the results demonstrate the capability of neural survival models to integrate complex data modalities for multi-disease risk modeling in primary prevention and illustrate the tremendous potential of machine learning models to disrupt medical practice toward data-driven prevention at population scale.Die Kosten im Gesundheitswesen steigen systematisch und derzeitige therapieorientierte Gesundheitssysteme sind nicht nachhaltig. Angesichts vieler verhinderbarer Krankheiten stellt die PrĂ€vention ein veritables Instrument zur Verringerung von Kosten und Leiden dar. Risikostratifizierung ist die grundlegende Voraussetzung fĂŒr ein prĂ€ventionszentri- ertes Gesundheitswesen um Personen mit hohem Risiko zu identifizieren und MaĂnah- men einzuleiten. Heute ist eine systematische Risikostratifizierung jedoch nur begrenzt möglich, da fĂŒr die meisten Krankheiten keine Risikomodelle existieren und sich verfĂŒg- bare Modelle auf einzelne Krankheiten beschrĂ€nken. Weil fĂŒr deren Berechnung jeweils spezielle Sets an PrĂ€diktoren zu erheben sind werden in Praxis oft nur wenige Modelle angewandt. Gleichzeitig versprechen komplexe DatenmodalitĂ€ten, wie Bilder oder -omics- Messungen, systemische Informationen ĂŒber zukĂŒnftige GesundheitsverlĂ€ufe, mit poten- tieller Relevanz fĂŒr viele Endpunkte gleichzeitig. Da es an dedizierten Methoden zur Ex- traktion klinisch relevanter Informationen fehlt, sind diese Daten jedoch fĂŒr die Risikomod- ellierung unzugĂ€nglich, und ihr Potenzial blieb bislang unbewertet. Diese Studie nutzt ma- chinelles Lernen, um die Anwendbarkeit von vier DatenmodalitĂ€ten in der PrimĂ€rprĂ€ven- tion zu untersuchen: polygene Risikoscores fĂŒr die kardiovaskulĂ€re PrĂ€vention, NMR Meta- bolomicsdaten, elektronische Gesundheitsakten und Netzhautfundusfotos. Pro Datenmodal- itĂ€t wurde ein neuronales Risikomodell entwickelt, um relevante Informationen zu extra- hieren, additive Information gegenĂŒber ĂŒblicherweise erfassten Kovariaten zu quantifizieren und den potenziellen klinischen Nutzen der DatenmodalitĂ€t zu ermitteln. Die entwickelte Me-thodik konnte polygene Risikoscores fĂŒr die kardiovaskulĂ€re PrĂ€vention integrieren. Im Falle der NMR-Metabolomik erschloss die entwickelte Methodik wertvolle Informa- tionen ĂŒber den zukĂŒnftigen Ausbruch von Krankheiten. Unter Einsatz einer phĂ€nomen- weiten Risikomodellierung erwiesen sich elektronische Gesundheitsakten als Quelle prĂ€dik- tiver Information mit hoher systemischer Relevanz. Bei der Analyse von Fundusfotografien der Netzhaut wurden Krankheiten identifiziert fĂŒr deren Vorhersage Netzhautinformationen genutzt werden könnten. Zusammengefasst zeigten die Ergebnisse das Potential neuronaler Risikomodelle die medizinische Praxis in Richtung einer datengesteuerten, prĂ€ventionsori- entierten Medizin zu verĂ€ndern
MetaOmniCity: Towards urban metaverse cyberspaces using immersive smart city digital twins
The movie - The Matrix (1999) - boosted our imagination about how further we can be immersed within the cyber world, i.e., how further the cyber world can be indistinguishable from the real world with the metaverse space travel. Nobody had expected involving the creators that the aspirational fictional virtual worlds such as "ActiveWorlds (1995)", and ``Second Life (2003)'' with many urban experiences embedded into a rich featured 3D environment would impact the way of experiencing our real urban environments. Are we going to feel/become ourselves - our cyber-physical presence (e.g., our augmented avatars) - in other mirror worlds doing many other things? Are the created imaginary worlds becoming a part of the real worlds or vice versa? The recent once-in-a-lifetime pandemic has confirmed the importance of location and time-independent Digital Twins (DTs) (i.e., virtual scale models) of cities and their automated services that can provide everybody with equity and accessibility by democratising all types of services leading to increased Quality of Life (QoL). This study analyses how the metaverse (3D elevation of linear Internet), that aims to build high-fidelity virtual worlds with which to interact with the real world, can be engaged within the Smart City (SC) ecosystem with high immersive Quality of Experiences (QoE) and an urban metaverse ecosystem framework â MetaOmniCity â that is designed to demonstrate a variety of insights and orchestrational directions for policymakers, city planners and all other stakeholders about how to transform data-driven SCs with DTs into virtually inhabitable cities with a network of shared urban experiences from a metaverse point of view. MetaOmniCity, allowing the metaversification of cities with granular virtual societies, i.e., MetaSocieties, and eliminating the boundaries (e.g., time, space and language) between the real world and their virtual counterparts, can be shaped to the particular requirements and features of cities. This can pave the way for immersive globalisation with the bigger and richer metaverse of Country (MoC) and metaverse of World (MoW) being an immersive DT of the broader universe with digitally connected cities by removing physical borders. MetaOmniCity is expected to accelerate the building, deployment, and adoption of immersive urban metaverse worlds/networks for citizens to interface with as an extension of real urban social and individual experiences

Sonic heritage: listening to the past
History is so often told through objects, images and photographs, but the potential of sounds to reveal place and space is often neglected. Our research project âSonic Palimpsestâ1 explores the potential of sound to evoke impressions and new understandings of the past, to embrace the sonic as a tool to understand what was, in a way that can complement and add to our predominant visual understandings. Our work includes the expansion of the Oral History archives held at Chatham Dockyard to include womenâs voices and experiences, and the creation of sonic works to engage the public with their heritage. Our research highlights the social and cultural value of oral history and field recordings in the transmission of knowledge to both researchers and the public. Together these recordings document how buildings and spaces within the dockyard were used and experienced by those who worked there. We can begin to understand the social and cultural roles of these buildings within the community, both past and present
