TEWI Colloquium

Prof. Qing Xu | College of Intelligence and Computing |  Tianjin University – China

Abstract: Visual scanning and gaze behavior are fundamental to everyday sensorimotor activities such as walking and driving. The coordination of the eyes and head plays a foundational role in visual scanning, and a deep understanding of the spatiotemporal dynamics of this coordination is undoubtedly important. However, relatively little is known about the computational and higher-order interactions between eye and head movements during visual scanning in sensorimotor tasks. Moreover, eye gaze directly reflects attention and its allocation. Data-driven measurements of gaze behavior provide a quantitative assessment of visual attention, revealing the mental and physical states of individuals. Situational awareness offers a robust and semantically rich framework for interpreting gaze behavior during sensorimotor activities. Nevertheless, few works have measured eye gaze data specifically from the perspective of situational awareness.

In this talk, I will present two closely related studies. In the first part, we apply a recent information-theoretic tool, Partial Information Decomposition (PID), to quantify higher-order components — uniqueness, redundancy, and synergy — in the spatiotemporal interactions between eye movements and head motion time series during a VR/AR-based walking experience. To our knowledge, this is the first data-driven approach leveraging an information-theoretic framework to characterize higher-order interactions in eye–head coordination during sensorimotor activities. In the second part, we propose four novel computational measures of gaze behavior grounded in the concept of situational awareness. These measures effectively assess the efficiency of visual scanning and sensorimotor performance, exemplified here using a driving task. Our results demonstrate that the proposed measures are effective and outperform closely related existing methods.

Bio: His current research focuses on the application of theoretical tools in information theory and complexity systems, based on employing VR/AR techniques. Since 2018, he has been doing interdisciplinary research relevant to data-driven analysis and modeling of human behavior in a computational manner, mainly based on using eye gaze and behavioral data (including head motion data, muscle data, and so on) and employing probability and information theoretic tools. In a nutshell, he does research related to understanding, explaining and modeling of human behavior (eye gaze and eye movement), by the exploitation of theoretical tools, mainly in information theory and complexity systems. He utilizes and extends the latest Partial Information Decomposition (PID) and Assembly Theory (AT), from the perspective of higher-order interactions of complex systems. Also, he works on low-level signal (image/video) processing, visualization and Monte Carlo adaptive sampling based image synthesis.

Learning from Software Engineering: leveraging retrospective and self- improvement in programming education

TEWI Colloquium

Prof. Tullio Vardanega | University of Padua

Monday, July 21, 2025 at 02:00 p.m. @ B01.0.204 | Lakeside Park |  University of Klagenfurt

Abstract: This talk focuses on the teaching of programming from an angle arguably applicable to any level of training, the more fully, the more advanced the level. Said angle is inspired by two sources, seemingly different from each other, but featuring very clear points of contact:

(1) the understanding of how learning works; and

(2) the transposition of some powerful practices of Software Engineering into

the instructional design of programming education.

The spinal cord of this talk is the idea that learning requires “reconciling with errors

to be able to leverage from them”.

 

Bio: Tullio Vardanega holds an MSc from the University of Pisa, IT (1986), and a PhD from the Technical University of Delft, NL, 1998. After working as PI for an R&D firm at Pisa between 1987 and 1991, he moved to the European Space Agency in the Netherlands, where he stayed until the end of 2001. Since January 2002, he is at the University of Padua, IT. Owing to his fabric of industrial and academic contacts, he has run numerous collaborative projects on international and national research funding. In addition to being a long-time member of IEEE and ACM, he is the Italian delegate in technical expert groups of ISO/IEC JTC1/SC22: WG9 (Ada) and WG23 (Programming Language Vulnerabilities). From February 2004 until February 2024, he was the chairperson of Ada-Europe. He now is the chair of the Ada User Society that oversees the continuation of Ada as international standard.

Battery energy storage systems for supporting electrical power distribution networks availability in Palestine

The Colloqium is CANCELLED!

Prof. Tamer Khatib

University of Klagenfurt | An-Najah National University, Nablus, Palestine,

Thursday, June 26, 2025

Abstract: The Palestinian electricity grid faces significant challenges concerning ampacity limitations within its electrical network due to the current political situation. These limitations are particularly problematic during peak demand periods when the current demand exceeds the network’s capacity. Furthermore, shortages in electrical supply, exacerbated by regional and geopolitical factors, often strain the network, leading to inconsistent power availability in certain areas. In addition to ampacity limitations and supply shortages, the Palestinian electricity grid also grapples with the challenges associated with integrating new PV system installations into the grid. The current electrical infrastructure often lacks the capacity and flexibility to efficiently incorporate these new energy resources. This integration requires significant upgrades to the existing topology of the grid to be capable of handling bidirectional energy flows, especially as IEC does not accept reverse power flow at the injection points. Moreover, the intermittent nature of solar power necessitates the development of robust energy storage solutions to ensure stability and reliability. Thus, integrating renewable energy resources into electrical distribution networks necessitates using battery energy storage systems to manage intermittent energy generation, enhance grid reliability, and prevent reverse power flow.  However, the intermittent energy generation from RE sources makes it necessary to have a battery energy storage system to control the supply, prevent reverse power flow, and enhance the grid’s voltage. Moreover, in some situations, BESS can support loads in the case that the main power supply cannot fulfill these loads. This lecture shows a real case of integrating battery energy storage systems into an electrical power distribution network with a capacity of 25 MVA/33 kV capacity with 7 MWp photovoltaic plants.

Bio: Tamer is a photovoltaic power systems professional. He holds a B.Sc. degree in electrical power systems from An-Najah National University, Palestine as well as a M.Sc. degree and a Ph.D degree in photovoltaic power systems from National University of Malaysia, Malaysia. In addition he holds Habilitation (the highest academic degree in German speaking countries) in Renewable and sustainable energy from Alpen Adria Universitat, Klagenfurt, Austria. Currently he is a Full Professor of renewable energy at An-Najah National University. He is also the director of An-Najah Company for Consultancy and Technical Studies. So far, he has 2 patents, 4 books and 140 research articles, while his current h-index is 42. He has supervised 5 Ph.D researches, 19 master researches and 65 bachelor researches. He is a senior member of IEEE, IEEE Power and Energy Society, The International Solar Energy society, Jordanian Engineers Association, and International Association of Engineers. His research interests mainly fall in the scope of photovoltaic systems and solar energy fundamentals. These interests include PV systems design and optimization, modeling and control of PV systems, hybrid PV/Wind systems, hybrid PV/diesel systems, Grid connected PV systems, sun trackers, MPPT technology, inverters in PV system, solar chargers, batteries and charge controllers, solar energy fundamentals, solar energy prediction, AI applications for solar energy and PV systems, wind power systems, wind chargers, wind energy modeling and prediction.

Fostering blockchain in Cloud and Fog environments with a Smart Contract recommender system

TEWI Colloquium

 Dr. Sandi Gec | Laboratory for Data Technologies | University of Ljubljana  | Guest Researcher @ ITEC

Wednesday, June 25, 2025 at 09:00 a.m. @ S.2.42 | University of Klagenfurt

Abstract: Public Smart Contracts enabling ledgers such as Ethereum may be used to automate the operation of Cloud computing applications in various contexts. This may contribute to fine-grained Cloud and Fog computing operations addressing important high-level functional requirements. However, integrating blockchain and Smart Contracts with Cloud and Fog computing architectures is still manual and often challenging. Software engineers must manually map their use cases‘ requirements with or without using available Smart Contract templates. This presentation comprehensively introduces a new Blockchain recommender system that helps facilitate the integration of Ethereum Virtual Machine-based Smart Contracts in Cloud and Fog computing architectures where the data flow includes off-chain mechanisms such as Smart Oracles that can further contribute to the seamless integration of applications and their deployment in Cloud and Fog computing architectures. The presentation first focuses on the primary motivation and the selected domains. Further, the recommender system main building blocks are presented. Finally, the evaluation of the system is not limited to experimental studies but also outlines further possibilities for tailoring the recommender system to specific target groups (e.g. students, DeFi developers, Cloud and Fog system developers, and others).

Bio: Dr Sandi Gec is a teaching assistant and senior researcher at the University of Ljubljana, where his main research domains are Cloud-to-Edge computing and software engineering focused on blockchain-related technologies. Between the bachelor’s and master’s degrees, he gained experience in the industry. He was one of the developers involved in the production phase of introducing the new „paperless“ Information System in 2011 for the biggest Slovenian Pediatric Clinic. Because of the industrial aspect, his research is often tailored with novel software engineering approaches focused on smart contracts and other related technologies. During his work in academia, he had the opportunity to work on many international research projects, primarily European, such as SWITCH, ENTICE, OntoChain, TrustChain, BuildChain (ongoing) and intercontinental, such as DECENTER which included European and Asian (e.g. South Korea) project partners.

Simulation and Behaviour Analysis Approaches of the Cloud-to-Thing Continuum

TEWI Colloquium

Ph.D. Attila Kertesz | University of Klagenfurt | University of Szeged

Monday, June 23, 2025 at 08:30 a.m. @ S.2.69, University of Klagenfurt

Abstract: The latest evolution in Information Technology has led to the appearance of the Cloud-to-Thing Continuum, which combine the Internet of Things (IoT), Cloud Computing and Fog Computing. IoT systems are composed of possibly up to billions of smart devices, sensors and actuators connected through the Internet, and these components continuously generate large amounts of data. Cloud and fog services assist the data processing and storage needs of IoT applications, while Blockchain services can support accountability and verification of certain actions. The location and behaviour of IoT devices can change dynamically, which calls for multicriteria optimization methods to be applied during the execution of these applications. The investigation and detailed analysis of such application and their underlying complex systems can be fostered by simulation solutions.
The DISSECT-CF-Fog simulator can be used to model a complex IoT-Fog-Cloud infrastructure, and a generic IoT application on top of it. It also supports the analysis of arbitrary actuator events and mobility capabilities of IoT devices in IoT-Fog-Cloud systems. The main metrics it considers for system analysis: execution time, resource/network usage, energy usage, and service pricing.
This talk presents a general overview of the simulation capabilities of the DISSECT-CF-Fog simulator, and discusses them through various application scenarios. It recent development directions will also be presented, which are triggered by the issues raised by the Swarmchestrate EU-funded research project. It aims to combine emerging technologies to create a completely decentralised autonomous and self-organised application management system suitable to manage hyperdistributed applications that span across different layers of the dynamic compute continuum.

Bio: Attila Kertesz is an associate professor leading the IoT Cloud research group at the Department of Software Engineering, University of Szeged, Hungary. He is also the Vice Dean of Public Relations of the Faculty of Science and Informatics of the University of Szeged. He graduated as a program-designer mathematician in 2005, received his Ph.D. degree at the SZTE Doctoral School of Computer Science in 2011, habilitated at the University of Szeged in 2017, and received the Doctor of the Academy (DSc) degree of the Hungarian Academy of Sciences in 2024. His research interests include the federative management of Blockchain, IoT, Fog and Cloud systems, and interoperability issues of distributed systems in general. He is the European PI of the SO-SMART EIG-CONCERT EU-Japan project, and a group leader at the Swarmchestrate EU HORIZON project. He has coordinated the FogBlock4Trust sub-grant project of the TruBlo EU H2020 project, and participated in several successful national and European projects, including NKFIH-FK 131793, GINOP Internet of Living Things, COST Actions CA19135, CA17136 and IC1304, ENTICE EU H2020, COST IC0805, SHIWA, S-Cube EU FP7 NoE and the CoreGRID EU FP6 NoE. He has more than 150 publications with more than 2500 citations.

Engineering Secure Socio-Technical Systems

TEWI Colloquium

Dr. Mattia Salnitri | University of Klagenfurt | University of Bergamo

Monday, June 16, 2025 at 05 p.m. @ S.2.05, University of Klagenfurt

Abstract Socio-technical systems are pervasive, comprising human, organisational and technical components that interact with each other to achieve common objectives. Examples of socio-technical systems are smart cities, airports, and hospitals. Each of these systems manages a large number of assets, such as the data that is stored and shared and the infrastructure itself. Security issues in socio-technical systems might lead to severe consequences: a security issue in a hospital might compromise the health of people, or a security issue in an airport might threaten the lives of passengers and staff. My research work consists of creating methods that support the engineering of secure socio-technical systems to prevent, detect and mitigate security issues. Given the intrinsic heterogeneity of the components involved, a mere technical solution is frequently not enough, while methods that consider technical, social and organisational perspectives are considered more effective.  In this presentation, I will provide an overview of such holistic methods that I have designed and validated. The methods allow the engineering of secure socio-technical systems, connecting and facilitating the design of aspects such as the objectives of actors, their procedural execution and implementation. On the technical side, I will present a method for the enforcement of security requirements using technologies such as blockchain. On the organisational and social side, I will present a method that strengthens what has been considered the weak link of the security chain, i.e., the people and their (un)secure behaviours.

Bio: Mattia Salnitri is an Associate Professor at the Management Information and Production Engineering department of the University of Bergamo (IT) and a Visiting researcher at the Engineering and Social Informatics Research Group of the University of Bournemouth (UK). Before that, he was an assistant professor at the Department of Electronic, Computer Science and Biotechnology (DEIB) of the Politecnico di  Milano (IT), and a post-doctoral research fellow at the University of Trento at the Department of Information Engineering and Computer Science (DISI), where he also earned his Ph.D.  in 2016.  Mattia’s main research interest is the design of secure socio-technical systems. He investigated various aspects of this research field, including security requirements elicitation and definition, security requirements enforcement, secure business process definition, verification of procedural constraints, and generation of secure code.

Connecting Competencies: Models for Teaching Informatics

Thursday, June 05, 2025 at 10.00 a.m. – @ B01.0.203, Lakeside Park Klagenfurt

Mag.Dr. Stefan Pasterk | Department of Informatics Didactics | University of Klagenfurt

Abstract: Competencies and competency models are key aspects of modern education and play a decisive role in the design of lessons. They provide teachers with a framework to define the skills and knowledge that students should acquire. Competency-based education is particularly relevant in a subject like computer science, which is rapidly evolving and where practical skills are often just as important as theoretical understanding. It is therefore not surprising that in various educational systems, competency orientation plays a role in educational standards or curricula for computer science. When looking at international models, the different forms and structures used to represent them are striking. For example, a three-dimensional competency model is defined in the educational standards for computer science teaching of the German Informatics Society. Switzerland’s Curriculum 21 describes a progressive development of competencies that together lead to an overarching competency. Austria’s curricula also rely on competency orientation, whereby lists are used for enumeration. A structured and standardized form of presentation is required to be able to carry out analyses or comparisons. A graph-based approach, in which competences are represented as nodes and their interdependencies as edges, helps to avoid the differences. This allows new metrics to be measured and compared, and practical information such as learning paths with start and end points can also be read out.

In this presentation, some competency models of computer science and of digital education will be compared, advantages and disadvantages will be discussed, and the graph-based approach will be presented, with the help of which differently structured models can be compared and analyzed.

Bio: Mag.Dr. Stefan Pasterk is assistant professor at the University of Klagenfurt, where he is conducting research on informatics didactics and in particular on competency models and their quality. He is involved in various projects such as the DigiFit4All project, which he is currently managing. In addition to the project, he is involved in the conception and implementation of the ‘Informatics Lab’, a laboratory for all people to get in touch with informatics topics. For the recent years, Mr. Pasterk has been actively involved in the training of future informatics teachers. Besides competency models, his research interests focus on technology enhanced and individual learning and computational thinking.

Unlocking nature’s secrets: Swarm intelligence for the optimization of production processes and other cyber-physical systems

Tuesday, July 08, 2025 at 01.00 p.m. – @ B02.2.05, Lakeside Park Klagenfurt

Dipl.-Ing. Dr. Melanie Schranz Bsc. | Lakeside Labs GmbH | Universität Klagenfurt

Abstract: Swarm intelligence is the collective behavior of decentralized, self-organized systems, inspired by natural phenomena like bee hives and ant colonies. This approach demonstrates that numerous small entities can collaboratively solve complex problems more effectively than a single large entity. The talk will explore the fundamental principles of swarm intelligence and bottom-up system design. Melanie Schranz from Lakeside Labs, Austria, will present their current research focusing on agent-based modeling and swarm-inspired algorithms. This bottom-up approach leverages the benefits of nature-inspired swarms, including robustness, adaptivity, and scalability. Their work aims to develop local, highly reactive rules for solving complex problems, like we have in production process optimization, but also in the edge-fog-cloud continuum.

Bio: Dr Melanie Schranz is a senior researcher and project lead at Lakeside Labs, specializing in the study of swarm intelligence and agent-based systems. With a PhD in information technology, her work focuses on developing decentralized algorithms for the coordination of autonomous cyber-physical systems of any kind, inspired by natural swarm phenomena like observable in ant colonies and bird flocks. Dr Schranz has contributed extensively to the field through numerous publications in high-impact journals and conferences, and her research has been pivotal in advancing practical applications of swarm in areas such as swarm robotics, bottom-up optimization in production processes or resource allocation in the edge-fog-cloud computing. She actively collaborates with academic and industrial partners, leading innovative projects that bridge the gap between theoretical research and real-world implementations.
