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.

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?

Introduction to the theme autonomous vehicles and robots

Fredrik Tufvesson, Johan Wester

We have learned that cars, boats and vacuum cleaners can now drive by themselves, but how do they really do it? What is it that makes a car know how to drive, and how do you beat a racing driver?

Lars Nielsen, Autonomous vehicles and critical maneuvers

During critical maneuvers, safety is really at the edge, if we turn too little we go off the road, if we turn too much we can get skidded and go off the road as well. With a good combination of gas, brake, and steering, the car can automatically help us avoid many of the fatal accidents we have on the roads today. Professor Lars Nielsen brings us to a new alternative approach to handling critical maneuvers where the car itself plans power and power directions to avoid accidents.

Daniel Axehill, How can a robot make thoughtful movements?

How does it really work when a self-driving car is to pocket park or a self-driving truck with a double trailer is to reverse around a corner? How do the vehicles think and how do they evaluate different options before they go into action? In the world of Assistant Professor Daniel Axehill, the user does not have to think about how the car or robot should get to a certain point, because there the robot or vehicle itself understands how it can move.

Software, software, software… Our whole life depends on the software doing what it should, never failing. How do we actually develop good complex software systems and how do we test that the software does what it is supposed to do? In this episode, we discuss software testing and development of large software systems, but what exactly is good code?

Vi Tran, Software Testing – Who watches the watchers

The software systems around us are growing and we cannot rely on manual software tests, but also these must be automated. How do we actually design automated software tests that test what they’re meant to test. Doctoral student Vi Tran takes us to the world of software testing and explains what good software tests really are.

Jürgen Börstler, Building large software systems — faster, cheaper and better?

What exactly is software quality? Any fool can write code that a computer can understand. Good programmers write code that people can understand. Professor Jürgen Börstler explains software quality to us and why we should not forget the human in the loop when developing software

Introduction to the theme Digital business models and legal aspects

Fredrik Tufvesson, Johan Wester

We have learned that if a service is free, it is really ourselves who are the product. But how does it really work out making money on open data and open source code., and why will digital service-driven growth accelerate as we move towards a more circular economy?

Per Runeson, Open source and open data

We have learned that if a service is free, it is really ourselves who are the product. Does the same apply to companies, or is there a point for companies to give away data to each other? Professor Per Runesson explains what can such a business model can look like and what methods and tools that are needed to support the collaboration.

Christian Kowalkowski, Digitalization and servicification

Companies are trying to create and capture more value, customers are making new demands, service-based business models are emerging, but how and why? Professor Christian Kowalkowski explains why digital service-driven growth will accelerate as we move towards a more circular economy.

5G has just arrived and already the discussions around the next generation communication technology, 6G, are beginning. Why do we really need new systems for wireless communication, what does the future look like and when do I have 6G in my pocket? In this episode, we explain the concepts and look at possible solutions to lower energy consumption, increase capacity and not least to bring secure and reliable wireless communication into the 2030s.

Fredrik Tufvesson, 6G – why do we need all these G:s?

5G is said to open up for augmented reality, mining from the office, remote surgery and much more. Many of us do not benefit from 5G and yet the researchers are starting to discuss the next generation of mobile communication systems, 6G. Professor Fredrik Tufvesson explains why we need to work with 6G now and what we can expect from mobile communication in the 2030s.

Ove Edfors, Large Intelligent Surfaces

Walls and houses covered with antennas, is that what we can expect from 6G? With large intelligent surfaces, we can enable data transfer with a fraction of energy compared to today, we can serve thousands of simultaneous users and perhaps also charge gadgets remotely. Professor Ove Edfors explains how we can meet the requirements for 6G with lots of built-in antennas in our surroundings.
