Abstract: The lecture will present the aesthetics of Yoko Taro’s Nier : Automata (Square Enix, 2017), the culmination of the legendary DrakeNier series (encompassing the three Drakengard titles plus Nier : Replicant, Nier : Automata, and the mobile »gacha« game Nier : Reincarnation).If contemporary »quality art video-games«—by analogy to »quality art television«—are to be understood as artworks, than one most show how they inherited not only the modern but also the classical art-forms in developing their own aesthetical language in the function of interactivity, thus allowing us to baptize them as a veritable Ottava Arte. Thus, by taking as our starting-point the understanding of video-games as Gesamtkunstwerk (»total work of art«), encompassing all the previous classic and modern art-forms (architecture, sculpture, painting, music, dance, literature, film), we will focus on these aesthetical aspects of Nier : Automata, broken down into the technical elements of its: world-building (»architecture«), character-design (»sculpture«), level-design (»painting«), soundtrack (»music«), gameplay (»dance«), story-telling (»literature«) and, last but not least, the role of cut-scenes (»film«). The main underlining idea of this analytical endeavor is that Nier : Automata managed to attain not only a devoted cult status among its followers but also to make a name for itself in the pantheon of contemporary quality art video-games precisely because it managed to develop at its fullest all of the mentioned elements in order to provide an immersive interactive experience like no other, thus embodying the aesthetical ideal of a video-game Gesamtkunstwerk.

Abstract: Der jüngste Bericht des Weltklimarates IPCC ist klar: der menschgemachte Klimawandel ist in vollem Gang. Schleichende Veränderungen sowie die Häufung und das Ausmaß von Extremereignissen nehmen signifikant zu. Bereits die seit „Paris“ angestrebten Klimaziele werden mit großen Schäden einhergehen und sehr teuer werden. Und es schaut nicht danach aus, dass man sie überhaupt erreichen will: die ursächliche Emission von Treibhausgasen ist global und hierzulande, trotz einiger Rückgänge, anhaltend sehr hoch. Erste Hinweise auf das Auslösen irreversibler Veränderungen und beschleunigender Rückkoppelungen im Klimasystem machen sich in der Zwischenzeit bereits alarmierend bemerkbar. Gleichzeitig werden die zeitlichen Handlungsfenster zur Anwendung durchaus bekannter Handlungsoptionen immer kleiner. Gesellschaftliche Veränderungen müssen sehr schnell, tiefgreifend und konsequent umgesetzt werden.

Bio: Georg Kaser ist Univ. Professor für Klima und Kryosphärenforschung i.R. und arbeitete seit 2003 zweimal als Leitautor und dann als Review Editor an insgesamt drei Berichtszyklen des Weltklimarates (Intergovernmental Panel on Climate Change – IPCC) mit.

Dr. Stefan Schauer | Austrian Institute of Technology

Abstract: The technical and processual interconnection among critical infrastructures (CIs) has drastically increased over the last decade, amplified by the ongoing digitalization in this sector. With the application of Industrial Control Systems (ICS) and Supervisory Control and Data Acquisition (SCADA) systems, CIs have evolved into highly complex ecosystems, becoming more and more dependent on each other. In such ecosystems, an incident happening within one infrastructure is no longer limited to this infrastructure alone but can have wide-ranging effects on dependent CIs as well as the society as a whole. The cascading effects of such incidents show that it is nowadays no longer sufficient to analyze and assess risks from the perspective of one organization alone. In this talk, we will take a closer look at these interdependencies within and among CIs and how to capture them in a structured way. Further, we will discuss a modelling and simulation approach that is able to describe on an abstract level, how much a critical entity (either a technical component or an entire infrastructure) is affected by an incident. This approach will set the basis for describing how the effects can propagate through the network of interdependent critical systems and infrastructures and for assessing the overall consequences of an incident as part of CI risk management.

Dr. Farzad Tashtarian | Department of Information Technology (ATHENA Christian Doppler (CD) Laboratory)

Abstract: In today’s digital landscape, video streaming has become a cornerstone of online content delivery, with applications spanning entertainment, education, teleconferencing, and live broadcasting. The importance of optimizing video streaming cannot be overstated, as Quality of Experience (QoE) directly impacts user engagement and satisfaction. However, the video streaming pipeline faces significant challenges, including maintaining high QoE, minimizing latency, and managing costs effectively. This talk addresses these critical issues by exploring holistic strategies that enhance the video streaming experience from source to destination. We will delve into the complexities of content provisioning, content delivery, and content consumption, emphasizing the necessity of an end-to-end approach. Additionally, by considering the entire streaming pipeline, we will discuss novel algorithms designed for optimizing end-to-end video streaming and demonstrate how these approaches can more effectively tackle the primary challenges of QoE, end-to-end latency, and video streaming costs.

Dr. Daniel Thilo Schroeder | Researcher at SINTEF

Abstract: In an era where efficient processing of complex graph structures is increasingly vital across various domains, such as social networks and biological system modeling, there arises a need for robust computational architectures. This Kolloquium introduces a novel approach that incorporates a higher-order pipeline architecture, aiming to enhance graph data processing. Integrating functional programming with object-oriented principles facilitates complex data processing through an intuitive, modular system. Central to this system is the notion of treating computation units as first-class entities, which promotes modular and type-safe environments. Additionally, the system includes a higher-order traversal abstraction to support flexible data manipulation strategies, a directed data-transfer protocol for efficient data flow management, and an operator model that enhances the robust lifecycle management of operations. The adaptability and performance of this system are further augmented by its capability to incorporate various graph computation models, such as vertex-centric and edge-centric processing. This approach contributes to scalable solutions that meet diverse computational needs without overcomplicating the user interface by offering a structured yet adaptable method for graph data handling.

Bio: Daniel Thilo Schroeder is a Research Scientist at SINTEF’s Smart Data group, where he develops high-performance, scalable platforms for processing and analyzing extreme data using massive graph representations, facilitated by serverless computing.

Alexandru Iosup | University Research Chair and Full Professor at the Vrije University of Amsterdam

Abstract: Our society has turned digital: From science to business, from online shopping to online gaming, from education to government, digital applications depend every moment on Information and Communication Technology (ICT) infrastructure. To pilot this infrastructure and navigate through it, we need detailed information and decision-making support, provided on-time, cheaply, and reliably. (We briefly argue non-data-driven approaches are currently unable to cope with real conditions.) In this talk, we argue that Operational Data Analytics (ODA) can provide these capabilities, with advances not only in monitoring and observability, but also in data sourcing and ontology mapping, data cleaning and filtering, data characterization and modeling, and process management. Furthermore, we argue a digital twin, capable of simulating both the current conditions and making long-term predictions, should be integrated with the ODA system – providing an advanced form of A – to help with resource management and scheduling, pipeline optimization, energy awareness, general system tuning, capacity planning, etc. We present a reference architecture for ODA, a partial analysis of the state of the art, and experience with data collection and its use in the digital twinning of datacenters. This work aligns with and benefits from collaboration with the SPEC RG Cloud Group and, among others, the EU Graph-Massivizer project, and the OffSense and 6G Future Network Services projects in the Netherlands.

Ana Lucia Varbanescu | Assoc. Prof. Dr. ir. at the University of Twente and University of Amsterdam

Abstract: “Computation” has become a massive part of our daily lives: in science, a lot of experiments and analysis rely on massive computation, in AI we use vast resources to train and use massive models, and in engineering we use complex simulations and digital twins to increase efficiency and productivity. Under the assumption that computation is cheap, and time-to-result is the only relevant metric, we often use significant computational resources at low efficiency. In this talk, I argue this approach is an unacceptable waste of computing resources, and demonstrate we can do better! By means of a couple of case-studies, I will show how performance engineering can be used for zero-waste computing, proving how efficiency and time-to-result can be happily married. I will further propose a co-design methodology that leverages such performance engineering methods to enable the selection of algorithms _and_ their effective deployment on suitable infrastructure. The approach relies on design-space exploration, driven by efficient search methods and compositional performance models. I will conclude by reflecting on the next steps and open questions that need answers to make this co-design approach feasible and applicable for more applications and systems.

Friday, March 15, 2024 | 10:00 am (CET) | Room: S.2.69 | Universität Klagenfurt Matteo Zavatteri | Assistant Professor  in computer science at the Department of Mathematics of University of Padua, Italy Abstract: A recent direction in Business Process Management studied methodologies to control the execution of Business Processes under several sources of uncertainty in order to always get to the end by satisfying all constraints. Current approaches encode business processes into temporal constraint networks or timed game automata in order to exploit their related strategy synthesis algorithms. However, the proposed encodings can only synthesize single-strategies and fail to handle loops. To overcome these limits I will discuss a recent approach based on supervisory control. The approach considers structured business processes with resources, parallel and mutually exclusive branches, loops, and uncertainty. I will discuss an encoding into finite state automata and prove that their concurrent behavior models exactly all possible executions of the process. After that, I will introduce tentative commitment constraints as a new class of constraints restricting the executions of a process. Finally, I will discuss a tree decomposition of the process that plays a central role in modular supervisory control.
