Abstract:

“After the COVID-19 epidemic and the consequent humanitarian crises that devastated the planet, there is a need to claim the role of investigative journalism as a watchdog and permeation system of social justice and democracy through public exposure. We are witnessing a sharp decrease in investment in this journalism specialty, either because of its impertinence in dealing with public management issues or because of the time spent on this type of investigation, which fundamentally takes longer than current journalism to produce results. In this sense, we perceive the influence of automation and artificial intelligence in information production processes to highlight all human tasks with the possibility of being carried out in less time by technological systems. Considering this possibility, there was an interest in studying, in-depth, how robotics and the application of artificial intelligence through platforms that support the usual procedure of journalism can help and even improve the global state of investigative journalism practice, nowadays. The Connect-the-Dots platform and the DODO assistant emerge as a hypothetical digital solution for some of the problems that investigative journalism currently faces. It could be a way to practically implement investigative journalism in its scope of innovation by integrating tools and open-source practices in a Design-Based-Research approach to knowledge archaeology.”

Abstract
The growing amount of research data and the recognition of their value in the scientific community has led to the development of policies, infrastructures, tools and services. Researchers are encouraged to open their data and make them FAIR (Findable, Accessible, Interoperable and Reusable) to ensure the verifiability of results and transparency of research, while increasing their value. In this context, Research Data Management (RDM) becomes a vital component of high-quality research and a regular activity for researchers. The Data Management Plan (DMP), provision of quality metadata, repository selection, and data publication are some of the activities that researchers need to undertake when following the Open Science policies. However, these activities are time-consuming and not obvious to researchers, requiring specific knowledge, effort and experience. To support researchers, institutions are looking for solutions and developing workflows, tools, systems and services that aim to meet RDM requirements of both researchers and funding agencies. Implementing any information system, tool or service at a research institution requires their development, testing and evaluation, as well as adaptation to existing regulations. In this work, we present the development of a DMP support system that meets RDM requirements and researcher needs. We also propose its implementation in the institutional infrastructure and workflow. We explore various aspects related to the DMP support system development, namely RDM and DMP requirements and legislation at the international and national levels, institutional project management and RDM workflows, existing initiatives, recommendations and tools. We introduce a collaborative DMP-building method based on collaboration between researchers and a data steward. We describe its application to case studies from different scientific domains, analyze the results and propose its systematic evaluation. We also propose a path that simplifies the DMP creation process, to make plans more standard, high-quality, and detailed, by implementing controlled vocabularies in the DMP support system. To this end, we apply the collaborative method on projects from the same scientific domain, identifying specific aspects for this domain and proposing terms that can be used with controlled vocabularies and possibly contributing to the design of Domain Data Protocols. The proposed DMP support system also considers the existing mechanisms of automation and interoperability, namely the machine-actionable DMP (maDMP) standard. We analyze the maDMP standard and existing tools created according to this standard and propose a DMP structure and a DMP workflow that can help to make the DMP machine-actionable. Finally, we suggest the implementation of the DMP support system in the institutional RDM workflow, and the interface to support researchers in DMP creation and RDM activities in general. Moreover, this work concludes that the DMP support system can be implemented in any institution, and used for projects in different scientific domains. The results constitute a guide for institutions that are still at the beginning of the development of the RDM infrastructure. The feedback from researchers shows that they need support in DMP creation and monitoring, not only at the planning stage of the project but also during its course and sometimes even after. They are very positive about the implementation of the proposed system, highlighting its importance and necessity. Along with researchers, institutions also benefit from the implementation of such a system by providing support to researchers in RDM issues, reducing the time to create plans, improving the quality of DMPs and making projects comply with the RDM and funders’ requirements, thereby contributing to the prestige of the institution.

Abstract

Generally speaking, a large-scale socio-technical system is formed up of individual entities that are distributed along with the system’s space and act asynchronously in their decision making processes. Each of the individuals bears its own goals and tends to behave rather “selfishly” and “greedily” to maximise self-welfare utilities. However, this characteristic will generally affect negatively the global efficiency and the designed (expected) emergent behavior of the system. Indeed, private road transport imposes negative externalities on society, such as road capacity restrictions, accidents, congestion, etc. An efficient mobility model must take into account the real costs of transport, and its regulatory framework will need to produce the conditions for people to make sustainable transport choices. Economic theories offer two types of instruments for addressing the problem of transport externalities: command-and-control and incentive-based policies.

Command-and-control policies are government regulations which force users to change their behavior. In that sense, recent approaches to optimise the traffic network throughput and reduce traffic congestion basically rely on “road pricing”. However, this approach ends up penalising the user and creating social inequalities as it imposes a tax to be paid. Only those who are insensitive to the price will benefit. Also, a population may not be responsive to the defined penalties, and thus, the regulation may not be efficient.

On the other hand, an approach that has gained the community’s attention is based on the implementation and design of incentive schemes in public policy. Incentives are seen as those external measures that try to motivate a behavior change towards the objective of the system. It appears to be a “fairer” vision, as it does not discriminate the user but rather tries to bring the society into equilibrium.

The domain area on which this PhD thesis is focused concerns open and competitive multiagent systems, such as the Intelligent Transportation Systems (ITS) and the electricity markets. This thesis intends to address the issue of whether or not incentive-centred designs can favour the emergence of social-aware behavior in agents that have selfish tendencies for a (global) optimal evolution of a socio-technical system. Traditional transport planning tools using the four-step model combined with standard economic appraisal methods are not able to provide such analysis. Instead, a multi-agent system (MAS) social simulations can be used as it is argued in the literature of complex systems.

Abstract

The aim of this thesis is to connect people with underwater environments while creating awareness for the problem of anthropogenic noise pollution through artistic creation. This dissertation addresses the lack of information on underwater noise discourse, especially on the vibrational aspect of underwater sound. By asking how to convey the experience of underwater soundscapes and their human disruption, it proposes two major directions that inform and complement each other. First, several underwater soundscape recordings were realised. They provide an understanding of the ambience of places and allow attunement with the natural world. Second, six practice-based research artworks based on the soundscape recordings and methods from acoustic ecology and ecoacoustics, focusing on anthropogenic sounds aimed at improving inclusion with nature while creating awareness of the noise pollution problem. The revised strategies and concepts included place attachment, emotional affinity, nature-connectedness and ecology of æffect. These artworks provide the setting for challenging audiences to bond with underwater environments by listening to their soundscapes while revealing a particular aspect of underwater sound. Moreover, they explore creative strategies for developing sonic experiences with the introduction, experience and performance of underwater sounds in artistic creation. Additionally, the artworks introduce and approach a natural phenomenon related to underwater sound (Luciferina – bioluminescence; SINØ III – cymatics; #switchoffandlisten – noise awareness campaign; DIS_turbation – bioturbation; Munda – cavitation; 2182kHz – auditory masking). The insights from the artistic experiences proved critical to continue producing innovative contributions and to create knowledge while influencing the communities. The significance of this study is that it informs the theoretical understanding of noise pollution impacts on aquatic fauna and underwater acoustics by introducing a focus on the vibrational aspect of underwater sound: particle motion. In addition, it informs the empirical understanding of the practice-based research on developing the proposed artworks. The novelty lies in addressing biological phenomena as a creative resource to intervene in underwater noise dialogue, reveal hidden qualities of vibroscape ecology (such as particle motion) and translate them in a more grasping way through the artistic artworks. As underwater soundscapes are increasingly a topic of concern globally, they become crucial to fostering an emotional affinity between people and natural environments, promoting inclusion with nature.

Keywords: ecological sound art, acoustic ecology, underwater soundscapes, anthropogenic noise, vibroscape ecology, nature-connectedness, ecology of æffect.

Abstract:

In this artistic research we start from the idea that digital works can be utilized for imagining and playing with yet impossible realities, for asking questions, and for portraying aspects of life such that we can explore these from a distance. This dissertation consists of three browser-based artworks programmed by myself in HTML, Javascript and CSS. These art experiences unfold on the screen, asking the person to interact with them in order to complete their meanings. The works incorporate, among other things, voice interaction through synthetic speech and speech input, the uses of which form an essential component of the works meanings. Each work is concerned with very different types of questions around migration, but overall, and as a triptych, the works explore what the movement brought about by migration implies from a human standpoint. The themes encompassed extend from exploring perspectives on language, where movement results in linguistic accent which provokes a notion of the Other through external difference (in We cannot take them all), or exploring the movement induced by the tension between our body and our personal needs and desires, but that is governed by (shifting) borders (in Speak out) and finally, at exploring migratory movement through the ambivalent relationship between the here and the there, the simultaneous processes of (re-)rooting and of living with homesickness (in Transplanted). While this research may not depart from clear research questions, it nevertheless arrives at observations about the artistic strategies that emerge when migration is explored through notions of voice/interaction. The works themselves open up a space of contemplation about the respective themes, inviting participation through voice.

Abstract:

The 4th industrial revolution is characterized by the digitization of industrial environments, based on the use of Internet of Things, Cloud/Edge Computing and Artificial Intelligence technologies. This technological advances are pushed by the ever-changing market that besides posing new business challenges, further increase the already existing complexity and related issues faced by industries at the operational environments. In this context, Cyber-Physical Systems (CPS) have been considered the new paradigm to develop the next generation of intelligent and distributed industrial automation systems that can achieve higher levels of flexibility and dynamic adaptation. Although data analysis has shown to be a key enabler of industrial CPS in the development of smart machines and products, the traditional Cloud-centric solutions are not suitable to attend the data and time-sensitive requirements. Aiming to cope with that, Edge Computing has been adopted to enable the data processing capabilities at or close to the physical components, complementing the Cloud solutions. However, defining what data analysis capabilities should be deployed along Cloud-Edge computational layers is not a straightforward task. Motivated by this challenge, this work proposes a conceptual framework that defines a modular agent-based architecture to design and develop cyber-physical components, together with a general guideline to support the system engineers to evaluate and determine the most suitable computing layer to deploy a given data analysis task. The proposed framework was implemented and evaluated considering some experiments based on a smart machine CPS testbed, and different scenarios that illustrate the benefits of distributing the data analysis capabilities along Cloud-Edge layers. The modular structure of the agent-based cyber-physical component architecture shown to be suitable, enabling to easily configure and distribute data analysis tasks along the CPS components and their deployment in the different computing layers, also providing a seamless and transparent interaction between the components. In addition, the proposed guideline and the Fuzzy Logic decision-making systems were used to recommend, in a less ad-hoc manner, the most suitable layer to deploy three data analysis tasks identified in the case study.

Abstract

 Photogrammetry is a technology increasingly used in games for modelling 3D characters and natural environments, with the potential of time-efficient generation of realistic meshes with a higher level of detail than is normally achieved via hand-modelling. In architectural environments, however, although textures are photoscanned, meshes are still hand-modelled. A key challenge is that architecture for games tends to rely on modular meshes, which require high precision and standardisation, whereas photoscans of real-world architecture tend to output irregular meshes that are hard to conform to modularity. This investigation aims to address this lack of integration with a focus on high granularity modular architecture for 1st and 3rd person 3D games. It starts with a review of 3D game graphics production and modular architectural assets for games, as well as the integration of photogrammetry in the creation of 3D assets for games and for 3D environment art in particular. This is followed by a theoretical contribution, consolidating the principles of modular architecture for games within the game development lifecycle. Next, it identifies the inherent incompatibilities preventing the integration of photogrammetry with modular architecture for games and postulates solutions, implemented and tested via a series of controlled experiments using commonly available software. It concludes that integration is possible, but that a manual process is presently required due to the lack of tools designed to conform detailed surfaces to the profile of standardised reference meshes. The investigation proposes a workflow to achieve sectional modularity of architectural photoscans via tileable borders to which mesh variations can be integrated via modular swapping. It proposes a modified game development lifecycle with longer pre-production and potentially multiple photoscanning sessions to incorporate architectural photoscans into modular game environment art production. Via this workflow, a wide range of types of photoscanned architectural surfaces and types of geometry were standardised into the requirements optimal for modular meshes for 3D environment art, indicating its viability as a workflow for game development in general.
