Senadin Alisic: Smart Cities and digital ecosystems
Cities face unprecedented pressures as populations boom and infrastructure systems are stretched. Development of smart cities and ecosystems around them is emerging as a strategy to mitigate the challenges for cities, especially those related to urbanization and climate. Although cities concentrate societal problems, they are also the world’s best laboratories for solutions. There is increased usage of sensors and connected devices to collect and analyse data. Today, cities are moving beyond the pilot stage and using data and digital technologies to deliver results that are more relevant and meaningful to residents. Crossways Växjö is an interesting project that shows how future cities will develop and which ecosystems will emerge, and which are the driving forces behind it.
Senadin Alisic works with digitalization and digital transformations at a strategic level. He has about 20 years of experience from IT and Business from Global players such as Capgemini, Ericsson, Sony Ericsson and IKEA.
Senadin received his master's degrees from Chalmers University of Technology in IT in applied Information Technology and in business administration (MBA) from Blekinge Institute of Technology. Today, Senadin works as a strategic advisor at Combitech and is an industrial doctoral student at Linnaeus University within the Industry graduate school DIA with a focus on the challenges of smart cities.
Mauro Caporuscio: Building the Digital Twin of the Organization
Cyber-Physical Systems, IoT, and Data-driven technology are the cornerstone of the Digital Twin of the Organization (DTO): e.g., an accurate digital representation of the organization, including physical devices, processes, services, people, and other elements. Employing a DTO would help organizations to change and innovate, thus enhancing their sustainability. However, building a DTO is perceived as a slow, resource-demanding, and extremely expensive process whose outcome is still uncertain. This talk introduces ALADINO (Aligning Architectures for Digital Twin of the Organization), a research project that aims at establishing a set of sound engineering methodologies, and tools for building and evolving DTOs.
Mauro Caporuscio is Associate Professor (Docent) in Computer Science at Linnaeus University (Växjö, Sweden). He has published several papers in the most important international journals/conferences and is serving on the program committee of international conferences and workshops. His research interests mainly focus on the application of Model-Based Software Engineering methodologies and techniques to the field of Self-adaptive Systems, with particular emphasis on decentralization and resilience.
Joel Cramsky and Manoranjan Kumar: Digital Twin - Data intensive applications at VCE
Volvo group has a vision that 50% of the revenue comes from customer services . Hence Volvo CE has also aligned to virtualize all products, systems, and components. With this Volvo CE aims to predict and verify their performance in the virtual space. To realize this vision, we started working into the directions of implementing a digital twin technology. This digital twin is the virtual representation of the physical machines which feeds the twins with data from sensors and edge-based algorithms.
One of the major tasks involved creating the accurate simulation models of the physical machines. Therefore, work is carried out to simulate customer use cases on AH and WLO.
Physical machines are providing the sensor data and further offline computations are done to find out the best sequence of simulation cases to represent the physical machines and their working environment. Other sensors are used for online calculations intended for services regarding safety and driver information or assistance.
Steps are also taken to build predictive models to solve customer problems. One of those problems is clogging to the engine where detailed studies are carried out to find a predictive model and corresponding online algorithms are being developed and deployed to the machine. This allows support or information to be given to the driver when the problem start to occur.
Joel Cramsky work as an R&D engineer at Volvo CE, has a Master in engineering physics from LTH Faculty of Engineering, and is an industrial PhD student at Linnaeus University. For the last ten years he has been working within simulation driven product development. Current research topics are digital twins, driver feedback and individual service intervals, among other interests.
Manoranjan Kumar is a Specialist Data analytics at Volvo CE, Braås, and is now pursuing an Industrial PhD at Linnaeus University, and has worked more than 15 years in automotive developments which includes trucks, buses and construction equipment. Has previously worked in the area of FE analysis, complete vehicle simulations and signal processing. Is currently involved in digital twin development for Volvo CE which focus mainly using Artificial intelligence (AI), Machine learning (ML) and data visualizations.
Per-Olof Danielsson: Data analytics at Volvo CE - purpose and future applications

Kobra (Farzaneh) Etminani: Information-driven care, taking steps towards the near future of healthcare!
We are entering a new era of health. Healthcare systems around the globe are facing value challenges. The most recent one was the virus pandemic and the sudden need for healthcare services. The second one is an escalating demand from long-term, chronic diseases and the ageing population and limited resources. Healthcare system, with all the longitudinal data it collects around patients across their lifecycles, is now in a place where it can take advantage of what data science and AI have to offer: endless opportunities such as diagnostics, and prognostics, to care personalization, in other words Information-driven care. The question is less whether AI can have impact, and more how to increase the impact while improving the user experience and adoption as well as solving the ethical challenges around its design and use.
Information-driven care is the vision of making healthcare decisions based on processed data (information) in real-time. Information-driven care provides an extraordinary opportunity to deliver significant benefits for patients, the regions, the municipalities, and the society. Reaching that vision, however, requires showing that data analytics can be trusted, demonstrating the value of using it, and showing how the transformation to information-driven healthcare should be done.
Kobra (Farzaneh) Etminani is an Associate Professor in Machine Learning, working at the Center for Applied Intelligent Systems Research (CAISR), Halmstad University, Sweden. She has a PhD in Computer Engineering from Ferdowsi University of Mashhad in 2013. She has worked on various topics and application areas within Machine Learning (ML), Artificial Intelligence (AI), Data Mining, and Deep Learning (DL) in the last decade, focused on healthcare, district heating, and mobility. Her main research interest is focused on solving real-world problems, which is focused on a healthier society, with the help of AI and ML, if possible and applicable. Her recent research focus is on patient trajectories and eXplainable AI (XAI) in precision healthcare at CAISR-Health research profile, where she serves as the Deputy Profile Leader for this center.
Alexander Darin Mattsson: The National E-infrastructure for Aging Research (NEAR)
This presentation will introduce the National E-infrastructure for Aging Research (NEAR) and inform how to apply for NEAR-data. Since the 1970s, Swedish longitudinal population-based studies have played a major role in geriatric research by exploring health-related conditions in older adults. Most of these studies are now part of NEAR, which is a unique project with the overall aim to build and run a National E-infrastructure for Aging Research. NEAR comprises 15 major longitudinal population-based studies on aging and health in Sweden and is financially supported by the Swedish Research Council (Vetenskapsrådet, VR). It is a collaboration between eight universities including Karolinska Institutet, University of Gothenburg, Lund University, Umeå University, Jönköping University, Uppsala University, Stockholm University and Blekinge Institute of Technology. Overall, NEAR is a multidisciplinary resource including 180.000 individuals aged 50 years or over who have been assessed by direct interview and clinical examination. NEAR integrates rich medical and social data, providing unique opportunities for researcher to identify sustainable intervention strategies for better health and to develop more effective care of the older population.
Alexander Darin Mattsson has a Ph.D. in social epidemiology and is presently working as a database coordinator within the National E-infrastructure for Aging Research (NEAR). The NEAR-project coordinates the existing databases from major population-based longitudinal studies on aging and health in Sweden. The aims of NEAR are to promote and facilitate aging research in Sweden, to increase international exchange and collaboration, and to enhance research quality and generalizability of research findings (NEAR).
Johnny Fägersten: After Sales Digital Twin - A revolution for a product maintenance!
Our perspective is aftermarket; from the time the product leaves the factory until it is phased out and scrapped. In Automotive, this area is changing in record time, and the technical answer is a digital twin that keeps a copy of each car and based on these, different services; spare parts, service instructions, diagnostics, etc. are offered.
As one of the first systems that goes live and are used in day to day business, we tell about our journey together with a car manufacturer in Gothenburg.
Johnny Fägersten is CEO of Sigma Technology Origo, a product company with a focus on delivering aftermarket solutions. Johnny has developed solutions for technical documentation and aftersales for 21 years in a variety of different industries, and now he’s finally see the big rapid change so many hoped for in our business.
Anders Logg: Creating Digital Twins of Cities
Digital Twins are digital replicas of physical things. They help to
make better-informed decisions, lowering costs and the chances of
failing in the real world. Recent advances in technology have already
enabled the creation of digital twins of cars or airplanes that can
now be modelled, simulated and optimised before they even leave the
This progress is about to become reality for something as complex as
whole cities. Digital Twins can simulate and visualize the pulse of
the city in real-time with layered data sources of buildings, urban
infrastructure, utilities, businesses, movement of people and
vehicles. Utilising this technology in the right way has enormous
potential for tackling some of the most pressing urban challenges,
such as segregation, flooding, pollution, traffic congestion,
spreading of fire & diseases.
In this talk, I will present an overview of our activities at the
Digital Twin Cities Centre, a Vinnova Competence Centre hosted by
Chalmers University of Technology in Gothenburg, including our most
recent results on automatic city model generation, simulation and
Anders Logg is Professor of Computational Mathematics at Chalmers and
Director of the Digital Twin Cities Centre. He has published an
extensive list of highly cited research papers and books within
computational mathematics with a special interest in automated
high-performance simulation of physical systems. Logg is founder
and CEO of ReSpace, a company providing cloud-based solutions for

Didem Gürdür Broo: Human-centred Cyber-physical Systems: How can we build better intelligent systems
High quality, trustworthy data can help organizations build strategies, capture value, increase the potential of automation and enable insightful and fast decision-making. Data could change the cities we inhabit through real-time solutions to challenges such as traffic congestion, air quality, energy distribution and monitoring. It can help us to build better ecosystems that support human flourishing. Data could enable us to be more effective, efficient, and sustainable. And it is already changing the world one industry at a time.
At the same time, data is often referred to as “the new oil”. We are, on one hand, benefitted from the revolutions that oil fuelled. Yet, on the other hand, one of the biggest threats that the earth is facing today is the unanticipated results of this revolution – climate change. Now that we are at the beginning of another new era, which many call the fourth industrial revolution, it is vital to understand how data-related decisions of today can affect the future and we focus on understanding the cause-effect relationships of our design decisions. Therefore, it is essential to not only focus on the opportunities of data but also understand the challenges around it.
This talk aims to provide an overview of the important characteristics of cyber-physical systems, common challenges related to data usage in cyber-physical systems. We will discuss strategies to deal with these challenges and have a brief introduction to three mindsets that can help us to do not only design intelligent systems but also do this in a human-centred and sustainable way.
Didem cares about the future of the world and nature. She is a computer scientist with a PhD in mechatronics, which can give you an idea about how much she loves to talk about the future and emerging technologies. She is a data person, always finds a way to talk about how important it is to know your data, use it to make decisions, and at some point, expect her to talk about art, visualizations, and visual analytics. Didem is a person who does not hesitate to talk about inequalities and point out her ethical concerns. She dreams of a better world and actively works on improving inequalities regardless of their nature. She is an analytical thinker with a passion for design thinking, a researcher with a future perspective, an engineer who likes problems more than solutions, and a teacher who likes to play during lectures. She is a good reader, sailor, divemaster, photographer, and drone pilot.
Currently, Didem is Marie Skłodowska-Curie Fellow on Human-centered and Sustainable Cyber-physical Systems. This fellowship will enable her to undertake a new research project in the designX research lab at Stanford University.
