How is the digitalization of Swedish industry going? What is happening in the public sector? Is Sweden a forerunner or not? What is needed going forward? In this episode, we give an introduction to ELLIIT tech talks, and why digitalization is vital for Sweden as a nation of knowledge and innovation.

Introduction to the theme industry 4.0 Fredrik Tufvesson, Johan Wester

Maria Kihl, The world is full of clouds, and there will be more

Clouds – What are they and where are they? Why do we use clouds? How does a distributed cloud infrastructure look like in 5G and the upcoming 6G as examples? How do they affect energy consumption?

Charlotta Johnsson, What are the pieces of the puzzle in smart industry?

What exactly is smart industry? What are the advantages, how does it work and what are the challenges? The choice of computer between the cloud server and the smartwatch matters greatly for performance, energy consumption and privacy – for both humans and machines. We discuss design decisions and priorities.

Fredrik Heintz, Privacy-Preserving Machine Learning

The use of AI and machine learning in different areas increase, but how can we ensure that we have ethical, reliable and privacy-preserving AI? Fredik Heintz guides us to how to avoid bias, get sufficient data for training and ensure that our privacy is preserved even when we use AI together with health data.

Gunnar Cedersund, Digital twins in health care

What exactly are digital twins, and how can we use them in the healthcare of the future? Gunnar Cedersund explains how it works. How we can make a digital model of ourselves and test different treatments on our personal artificial twin before the treatment is performed in reality.

Kalle Åström, Mapping and positioning with images, sound and radio

With the help of information from satellites, radio waves, images and sound, we can soon let robots catch a hair in the air, but how does it work? How can we really figure out where things are? Professor Kalle Åström explains how different positioning techniques work, what we can use them for and the mathematics behind.

Bo Bernhardsson, Navigation and radio channel estimation, – A story about a PhD Thesis

Professor Bo Bernhardsson explains radio-based navigation. We dive into the background of a doctoral thesis by the former PhD student Anders Mannesson. What does it mean to do a PhD, how does a thesis come about, what does it contain, and what was the problem that Anders solved?

Liang Liu, System-architecture-device codesign to bridge theory and practice

Associate professor Liang Liu leads us through the world of digital processing. What are the trends and requirements and how can we actually meet the processing demands of 6G and AI without running out of power using efficient techniques such as hybrid computing and in-memory computing?

Yousra Alkabani, Acceleration: From the General to the Specific

Accelerators can have many meanings, but what are accelerators for digital processing and how can we take advantage of them in order to improve performance by orders of magnitude? Associate Professor Yousra Alkabani discusses accelerators, data flow graphs and how application specific solutions can be used to meet processing requirements of the future.

Introduction to the theme Next-generation software technology – more than just text
Fredrik Tufvesson, Johan Wester

In robotics, movements have long been “recorded” and then based the programming of the robot on the recording. With machine learning and other AI techniques, steps are not being taken towards using recorded eye movements to give programmers better support in programming. With similar thinking, perhaps a future 1177 could let your voice mode reveal how you feel.

Johan Sanmartin Berglund, Your voice tells you when you are ill?

The voice can be a tool for the diagnosis of diseases. Professor Johan Sanmartin Berglund explains how we can use technical aids and AI to analyze what the voice really says about our health. By following the patient’s voice, the researchers hope to be able to follow up on treatment and control medication in a better way.


Emma Söderberg, Eye movements give us more effective programming

Software is everywhere, it grows and easily becomes complex. We need tools for building good software, tools for programmers. Associate Professor Emma Söderberg talks about software development, code review and how our eye movements can give us better programming.

Fast computers, large amounts of data, machine learning, logs from large systems and smarter algorithms allow us to identify dependencies that we have never been aware of before. Dependencies that could be cause and effect and thus provide invaluable knowledge previously being invisible to us. How does it work, how do we make it visible and is it really secure?

Zheng Chen, When Complex Networks Meets Decentralized Machine Learning

The voice can be a tool for the diagnosis of diseases. Professor Johan Sanmartin Berglund explains how we can use technical aids and AI to analyze what the voice really says about our health. By following the patient’s voice, the researchers hope to be able to follow up on treatment and control medication in a better way.

Ingrid Hotz, Big data science from numbers to insight

Seeing is believing you often say, but how can we visualize complex processes to create new insights? Professor Ingrid Hotz takes us to the world of visualization to show us how we can make sense of the data is around us.

AI-enabled digitalization of both good and evil intentions challenges how we handle justice, integrity, security, transparency and the division of responsibilities. We give examples of problems and explain principles for how they can be tackled – but also show that we sometimes have to choose what we mean by justice, convenience and security before we move on.

Introduction to the theme Design for security, privacy, and trust, I

Fredrik Tufvesson, Johan Wester

Christian Gehrmann, Why don’t the hackers leave our systems alone, and what can we do about it?

Every leap in the history of technology usually leads to consequential problems. Digitalization opens up fantastic opportunities but unfortunately also for the hackers who do not leave our systems alone. Professor Christian Gehrmann explains the paths to a safer digital future where we plan very carefully before creating a new digital service, where we use the latest protection mechanisms and also have a plan for how problems that nevertheless arise will be handled.

Elena Pagnin, Enhancing Data Authentication

We live in a digital era where almost everybody owns and uses a couple of digital devices. Every time we send some digital information we take for granted that it will be received precisely as it was sent, but how can we be sure of that? Assistant Professor Elena Pagnin brings us to the world of digital signatures and explains how they can be used to prevent hackers from changing the data we all are sending around.

Introduction to the theme Design for security, privacy, and trust, II

Fredrik Tufvesson, Johan Wester

A new car can call 112 itself if it crashes,  with vehicular communication we can even avoid crashes and see around corners. However, to make sense the vehicle must tell where it is. We want to protect our personal data and privacy, but we also want efficient, secure and smart IT. Sometimes, in fact, we simply have to choose between integrity and security. The choice can partially be made when developing the hardware, but even the most sophisticated systems can leak data and reveal information. How does it really work? How can we as consumers take a stand on the issue, and are we prepared to sell out our privacy?

Mark Dougherty, Analysis of Electromagnetic Emissions from IoT Devices

Encryption has changed digital forensics. At the moment data are often unencrypted, some information leaks out through the side channel, and we may be able to determine something about it by looking at the behaviour of the physical device using the data. Professor Mark Dougherty explains how we can find out things going on inside the chips by measuring electromagnetic emmissions.

Johan Thunberg, Traffic safety for connected and cooperative cars

Vehicle communication is the way forward to get more efficient and safer transports. Associate Professor Johan Thunberg explains different levels of autonomy and how communication can get road users to drive together instead of against each other. What could go wrong? How can we help vulnerable road users and how do we avoid collisions?
