So, there is a need for alternative sustainable solutions. Elise (Electric Aviation in Sweden) is a research project that has investigated how to plan and utilize electric aircraft in Sweden.</b></p>The development of electric aviation is yet in its infancy, but there are already prototypes of electric airplanes flying today. Even though it will take a lot of development before long distance flights can be replaced, this might be a technology that will re-draw the map for transportation. A third of all domestic flights in Sweden are shorter than 400 km. Short-haul flights have been identified as an area where electric airplanes can, not only replace conventional airplanes but also, enable new flight routes to more communities in rural areas. The expansion of new routes can also be a way to sustainably replace transportation on the ground. <br /><div><br /></div> <div><h2 class="chalmersElement-H2">Spin-off aviation company</h2></div> <div>Heart Aerospace is a new small aviation company that is direct spin-off from the research project Elise. Anders Forslund, researcher at Elise, decided to start up the company after receiving funding from the Silicon Valley based Y Combinator. Heart Aerospace are now located in Gothenburg and aims to have a 19-passenger electric airliner certified for commercial flight by 2025 with an operating range of 400 km. </div> <div><br /></div> <br /><div><img src="/SiteCollectionImages/Institutioner/IMS/Produktutveckling/AndersForslund.jpg" alt="Anders Forslund" class="chalmersPosition-FloatLeft" style="margin:5px 30px;width:164px;height:184px" /></div> <div><br /></div> <div>– Sweden has a strong history of research and development in aviation. I think that electric aviation has the potential to be a new big market that can benefit both the climate and Sweden as a country. Norway, where over half of the flights are considered short distance, have decided to electrify all domestic flight before 2040, says Anders Forslund.</div> <br /><br /><br /><br /><div><h2 class="chalmersElement-H2">About Elise</h2></div> <div>Elise is a collaboration between Chalmers University of Technology, RISE Viktoria, QRTECH and the Civil Aviation Administration, with a reference group including SAAB, GKN Aerospace, Volvo Cars and Gothenburg City. </div> <br /><div>Funded by the Swedish innovation agency Vinnova.</div>Thu, 05 Dec 2019 00:00:00 +0100https://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Transports-of-the-future-at-Universeum.aspxhttps://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Transports-of-the-future-at-Universeum.aspxTransports of the future at Universeum<p><b>​On December 4, it is time for Future Day at Universeum. Nearly 400 school students visit Universeum for the final of the Future Transport project, and take part in an exhibition where Chalmers, among others, contributes.</b></p>​<span style="background-color:initial">Future Transport is a recurring school project, and a competition, where school students from grades 7 and 8 create sustainable solutions for the transport of people and goods. This autumn, the project started in September and ends with a fair on the Future Day on Wednesday, December 4. Each class is assigned a booth where they present their solution. A jury consisting of representatives from participating partners will visit the booths and assess the competition entries. The winning class is awarded SEK 10.000.<br /><br /></span><div>During the Future Day, the school students will meet researchers, business leaders, experts, politicians and officials at the fair. Chalmers Transport Area of Advance, represented by Chalmers Formula Student, will be at site to display the formula car built, and driven in competitions, by the students this last year.<br /><br /></div> <div>“We want to inspire future engineers by showing that electric racing cars are faster and just as impressive as petrol driven ones. The motto for Chalmers Formula Student is “We Deliver the Engineers of Tomorrow”, so it’s a good fit for the Future Day, says Adam Olsson, one of five students from the team who staff the booth during the day.<br /><br /></div> <div>The school project Future Transport was first started in 2012, to create interest in transport, transport systems and technology development. The aim is to motivate and inspire students' interest in technology and sustainable development, as well as to show the multitude of professional roles in the transport sector. The project also aim to open up dialogue between young people and adults, while highlighting the interaction between man, nature and technology.<br /><br /></div> <div>Note: <a href="http://www.chalmersformulastudent.se/">Read more about Chalmers Formula Student here</a>.<br /><br /></div> <div>Text: Mia Malmstedt</div> <div>Photo: Universeum</div> <div><br /></div>Thu, 28 Nov 2019 12:00:00 +0100https://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Watch-the-Fulbright-inaugural-lecture-with-Professor-David-Blekhman.aspxhttps://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Watch-the-Fulbright-inaugural-lecture-with-Professor-David-Blekhman.aspxWatch the Fulbright inaugural lecture with Professor David Blekhman<p><b>We are standing in the doorway of a transportation revolution with the advent of electrified and autonomous vehicles&quot;. How can hydrogen be the fuel of the future? Professor David Blekhman is an expert in the field of hydrogen infrastructure and has been selected as a Fulbright Distinguished Chair of Alternative Energy Technology.

At this age, our kids are already old enough to tell us that we are not leaving them the world in a pristine condition. Rapid climate change, multiple sites of human operation, and rampant exploitation of the Earth’s resources are the drivers for finding solutions that are more humane. Hydrogen is one of the pathways we are exploring to address these challenges. Hydrogen has its positive properties as well as challenges. But it certainly is and will be the technology of interest,” says David Blekhman, ​<span style="font-size:14px"></span></span><span></span><span style="background-color:initial;font-size:14px">professor at California State University Los Angeles and Technical Director of  Hydrogen Research and Fueling Facility, He</span><span style="background-color:initial"> will conduct research an</span><span style="background-color:initial">d teach at the Department of Mechanics and Maritime Sciences at Chalmers for one year.</span><span style="background-color:initial"> </span></p> <p><span style="background-color:initial"><br /></span><span style="background-color:initial">“It means a lot for Chalmers to have David here for one year, participating in education, research collaboration and outreach activities,” says Maria Grahn, associate professor, Director of Energy Area of Advance, and host for David Blekhman.</span><span style="background-color:initial"><br /></span></p> <p>His research fits well into what many researchers already do at Chalmers. Maria Grahn especially highlights his broad network within academia, industry and other actors and appreciates David Blekhman´s natural ability to explain in a pedagogical way:</p> <p>“He is a true inspiration for me and for the researchers he has met. I encourage everyone to register and join the inaugural lecture and take the opportunity to meet David”.</p> <h3 class="chalmersElement-H3">Fulbright Distinguished chair</h3> <p>Professor David Blekhman has been selected as a Fulbright Distinguished Chair of Alternative Energy Technology. He has expectations to establish new collaborations and research projects that he could continue in the future.<br /></p> <p>“Chalmers is a premier European institution with leading researchers in their field. My hope is that my contributions will expand projects already under development here at Chalmers. The university currently is the resource for contacts and my home base from which I am to travel to various hydrogen sites in Scandinavia. I look forward to hosting my colleagues at Chalmers back home at my institution in Los Angeles when visiting California”, says David Blekhman. </p> <p>He looks for projects that result in physical realization and real-world testing in the area of alternative fuels, advanced transportation and variety of topics in renewable energy. </p> <p>David Blekhman´s major focus area for the past ten years has been the construction and operation of the Cal State LA Hydrogen Research and Fueling Facility. </p> <p>“Due to the inherent complexity and being a new technical undertaking, hydrogen infrastructure still has a number of lessons to learn and challenges to overcome. In addition to hydrogen, I have worked in the area of fuel cell and hybrid vehicle development,” says David Blekhman. </p> <h3 class="chalmersElement-H3">Hydrogen – part of a sustainable future</h3> <p>Several years ago, Los Angeles hosted a small conference on the Scandinavian Hydrogen Highway. Ever since David Blekhman wanted to see it for himself. </p> <p>“As a part of my project at Chalmers, I plan to visit and asses the performance of hydrogen stations in Sweden, Norway, Denmark and wherever else that highway leads. I also look forward to forging collaborations with local researchers and industry”.</p> <p>The evolution of hydrogen as a fuel is a complex question with uncertain answers. <br /><span style="background-color:initial">“My general view and the hope for my work is that hydrogen and electricity will co-exist in powering our vehicles very similar to what is happening with gasoline and diesel. I also think that some applications will be better suited for hydrogen and some for electric,” says David Blekhman. </span></p> <p>Recently, energy storage has been adding another dimension to hydrogen as energy storage in intermittent renewable energy generation. David Blekhman thinks that this could be a part of building a circular and sustainable society.<br /></p> <h3 class="chalmersElement-H3">Many applications for hydrogen</h3> <p>Twenty years ago, hydrogen was mainly targeting the light duty transportation, but the electric vehicles are now offering strong competition for short and medium transport. In response, hydrogen is evolving with heavier duty applications where additional range is associated with lighter than battery energy storage on board. Applications are currently developed in marine and heavy duty transport. </p> <p>“The large-scale of hydrogen operations is around the corner. Following the California leadership of the past twenty years, Japan, Korea, Germany and others have been rapidly developing their hydrogen infrastructure. Several stations also operate in Denmark and Norway. I am hoping that there will be several more in Sweden in a short time”.</p> <p>The technology for producing hydrogen on a large scale from natural gas has been well established due to space exploration and other broad technologies. This will be a transitional pathway for some time allowing for the development of the hydrogen infrastructure. As renewable energy resources become more prevalent, electrolysis will be the source of hydrogen.</p> <p>“Another scenario we are not talking about enough is the controlled nuclear fusion leading to a completely new world. That would also be based on hydrogen,” says David Blekhman.</p> <p>David Blekhman will conduct research and teach at the Department of Mechanics and Maritime Sciences during the 2019/2020 semesters. David Blekhman gives a special mention to his host Dr. Maria Grahn and says that her professional network is amazingly broad and she has generously shared her contacts with him, and also to professor Sonia Yeh who a few years ago was a Fulbright chair at Chalmers.</p> <p></p> <p>“My experience at Chalmers is nothing short of amazing. People are warm and genuinely interested in my work and share interesting opportunities that I could engage in”, he concludes.<br /><br />By: Ann-Christine Nordin and Anders Ryttarson Törneholm, ​<br /></p> <p><br /></p> <p><a href="/en/about-chalmers/Chalmers-for-a-sustainable-future/sustainability-day2019/Pages/default.aspx" style="outline:0px"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />The lecture is a part of Chalmers Sustainable day</a><br /><a title="link to registration" href="https://ui.ungpd.com/Surveys/59a1c80e-b4ba-42d8-9419-0291efe60eb8" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" style="background-attachment:scroll;background-origin:border-box;background-clip:border-box" />REGISTRATION (Masterclasses, workshops and Fulbright inaugural lecture) ​​</a><br /></p> <p><br /></p> <p><strong>The program for the Inaugural lecture of the 2019-2020 Fulbright Distinguished Chair in Alternative Energy Technology:</strong></p> <p><br /></p> <p><strong>​14:30-14:45</strong> Opening, moderator Maria Grahn, Director of Energy Area of Advance<br /></p> <p>Welcome speech, Stefan Bengtsson, president and CEO</p> <p><strong>14:45-15:00</strong> Sonia Yeh to speak about the Fulbright Distinguished Chair program and value it has had in her case, her research at Chalmers</p> <p><strong>15:00-16:00</strong> David Blekhman, Inaugural Lecture, “If you build it, he will come” – Hydrogen Infrastructure</p> <p><strong>16:00-16:30</strong> Bill Elrick, Director of California Fuel Cell Partnership to speak remotely on Hydrogen Developments in California perspective</p> <p></p> <p><strong>16:30</strong> Reception​​</p>Thu, 31 Oct 2019 09:15:00 +0100https://www.chalmers.se/en/departments/m2/news/Pages/Railway-researchers-awarded-for-societal-impact.aspxhttps://www.chalmers.se/en/departments/m2/news/Pages/Railway-researchers-awarded-for-societal-impact.aspxRailway researchers awarded for societal impact<p><b>​Their research has facilitated for freight transports through Europe, and also made it easier to plan maintenance. For this, the research group now receives Chalmers Impact Award.</b></p>​<span style="background-color:initial">“Exiting and surprising”, says Anders Ekberg, Professor at the Department of Mechanics and Maritime Science and director of Charmec.</span><p>The competence centre Charmec is a national centre that gathers important railway actors – the Swedish Transport Administration, SJ and Bombardier just to mention a few. The researchers at Charmec are now acknowledged for contributing to new European rules that simplify for trains travelling across borders, and also for new ways to predict cracking in rails and wheels.</p> <p>“It’s not always easy to operate in the field between research and industry. When we address industry representatives, some of them believe research to be too theorizing. On the other hand, when we speak to the academy, some view us as consultants. Therefore, it is highly important that someone else now states that what we do is absolutely right”, says Anders Ekberg.</p> <p>“If you find the right balance between industry and academia, that’s when the big impact can occur. This award is a confirmation of that fact.”</p> <h2 class="chalmersElement-H2">Facilitates freight transports on rail</h2> <p>The research impact, for which the group is now awarded, has clearly benefited both train operators and infrastructure. The previous European lack of coordinated alarm limits for wheel loads made it difficult to transport goods through Europe; even to the extent that trains have had to cancel the journey and return to the home country. The new harmonising rules, which are based on the research group’s calculations, facilitate the expansion of freight transports on rail and thereby benefit the climate.</p> <p>The same can be said for the crack formation predictions. With new calculation models, it is easier to predict when a wheel or rail need maintenance, making it possible to schedule maintenance instead of waiting for unexpected stops when something is broken.</p> <p>“One of the challenges for coming decades is to increase the punctuality of train traffic, while at the same time we will have an increasing amount of trains operating the railways. This requires better precision in both train and rail maintenance”, says Anders Ekberg.</p> <h2 class="chalmersElement-H2">Charmec a prerequisite for success</h2> <p>The breadth and weight of the collaborations within Charmec are a prerequisite for the impact of science in society, says Research Professor Elena Kabo.</p> <p>“It creates a long-term perspective – our impact is based on decades of research – and a synergy between industry and academia, which enables us to solve relevant problems while having a strong scientific base. Charmec also provides better opportunities for collaborations between different research disciplines, which make it possible to come a long way”, she says, adding:</p> <p>“I believe the fact that we now receive this award can broaden the view on the benefits of applied research, and the understanding that it is based on more basic research. Both basic and applied research are important. But it is often with the combination of both that a major societal breakthrough can occur.”</p> <h2 class="chalmersElement-H2">Diploma, flowers and speeches at ceremony</h2> <p>Chalmers Impact Award was presented by Fredrik Hörstedt, Vice President of Utilisation, at a ceremony at Veras Gräsmatta.</p> <p>“We build knowledge that finds its way out in society. Most often we do this through our students who enter the society with new skills. But we also work with many other approaches to utilise our knowledge – for example as advisors, close to industrial partners or together with research institutes”, Fredrik Hörstedt said, and continued:</p> <p>“This award puts the spotlight on those who have succeeded in creating great values for society. The researchers at Charmec have really shown the potential; how we at Chalmers can help solve societal challenges and at the same time build a strong industry.”</p> <div><br /></div> <p><strong>Text:</strong> Mia Malmstedt<br /><strong style="background-color:initial">Photo:</strong><span style="background-color:initial"> Charlotte Emlind Vahul</span></p> <p><span style="background-color:initial"><br /></span></p> <h3 class="chalmersElement-H3">FACTS Chalmers Impact Award</h3> <p>Chalmers Impact Award is 2019 given for the second time.

The partnership entails cooperation both in research and education. “An extremely important partnership,” says Stefan Bengtsson, President at Chalmers.​</b></p><div><div>The renewed agreement, which states that Volvo Group will continue to be one of Chalmers’ so-called strategic partners, was celebrated with a ceremony on October 9. This marks the continuation of a long-term cooperation that was started back in 2009.</div> <div>Significant for a strategic partnership is – among other things – an extensive collaboration in research, expanded job opportunities for recently graduated Chalmers alumni, a diversity in collaboration over Chalmers different research disciplines, as well as focus on highlighted topics of interest.</div> <div>“For us, the partnership with Volvo Group is extremely important. Chalmers strives for highest possible quality in both education and research, but that is not enough – we must also collaborate with both industry and society as a whole. Collaborations make us better and give us relevance”, says Stefan Bengtsson.</div> <div>“Volvo is a very important partner, perhaps the most important one. We have extensive cooperations of great significance.”</div> <br /><strong>Long-term collaboration</strong></div> <div><div>In 2009, Volvo Group started the programme VG APP, Volvo Group Academic Partner Program. Within this framework, the company currently has nine partner universities around the world.</div> <div>“VG APP is a strategic and long-term Volvo Group initiative, and consists of three modules: Research, Talent and Learning. We see the word partner as significant. A partnership entails building a long-term relationship that benefit both, and where we can both grow together”, says Lars Stenqvist, Executive Vice President Volvo Group Trucks Technology, and continues:</div> <div>“Chalmers has an exclusive position within Volvo Group, as it is one of only two universities with which we work within all three modules of the VG APP.”<br /><br /></div> <div>The collaboration between Chalmers and Volvo Group has, over the years, led to a large number of national as well as international research projects, which in turn have resulted in a multitude of scientific publications. The partnership has also entailed joint doctoral students, guest lectures, development of competence and projects for students; including both thesis projects and international student projects.

Among the topics were self-driving vehicles, block-chain and adaptations to a new market.</b></p>​<span style="background-color:initial">Approximately 300 representatives from industry and academia had gathered when Sinisa Krajnovic, Head of the Transport Area of Advance, entered the stage to welcome all.</span><div>“We always try to choose a theme of current interest for our Initiative seminars. Right now, we are discussing automation and mobility, but also shared economy”, he said.</div> <div>New technology makes it possible to label goods, in order to keep track not only on its location, but also the surrounding’s temperature and humidity. Trucks are also able to transfer data, which shows the vehicles current status. So:</div> <div>“The entire traffic system is becoming more and more automated. Transport is no longer just about having enough buses in the city network, but about what apps we use.”<br /><br /><strong>Impossible to foresee the future</strong></div> <div>Robin Teigland, Professor in Management of Digitalisation, gave the Key note lecture and talked about how society and economy is changing. She quoted Bill Gates:</div> <div>“We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. So how will we be able to work, when we don’t even know what we don’t know?”</div> <div>One way to view market demands, is to think about what we need and answer the question with a verb instead of a noun, Robin Teigland said. To illustrate, she showed a picture of a woman waving at a taxi.</div> <div>“Think about what she wants to do, instead of what she wants to have! Where does she want to go? And why? View technology as a means, not as an answer.”<br /><br /><strong>Topics varied throughout the day</strong></div> <div>Henrik Sahlin, from Ericsson, talked about autonomous cars, the technology needed and challenges to solve. The car must be able to “talk” to other cars, with infrastructure, pedestrians and networks. What happens if the car loose internet connection? Do we need to wait for 5G in order for this to work?</div> <div>Chalmers Professor Maria Ljunggren Söderman gave an insight into necessary metals for the automotive industry – 25 different ones – which are not currently being recycled. MariAnne Karlsson, also a Professor from Chalmers, talked about MaaS; Mobility as a Service.</div> <div>“We see a paradigm shift coming. In the future, actors will present their offers together. And this can make people change their behavior, for example make them not buy a car”, she said, and was replaced on stage by Hans Arby, whose company Ubigo offers exactly this kind of service.</div> <div>During the afternoon, Érika Martin's Silva Ramos from Gothenburg University spoke about user preferences, Klas Hedvall from Volvo GTT talked about vehicle maintenance in the connected future, and Jonas Flodén from Gothenburg University about block-chain.</div> <div>Last on stage, before the closing panel discussion, was Ikea’s Stefan Holmberg, who presented the company’s challenges in a new market.</div> <div>“We started at a time when people had more time than money. Today it’s the other way around; people have money, but not time. Our department stores provide inspiration, but most visitors immediately start looking for the shortcuts. They do not have the time and desire to walk around the store for several hours.”<br /><br /><strong>Important to ensure future competences</strong></div> <div>The panel discussed how to ensure the competence needs in the future. Industry needs are difficult to foresee, which means that competences of the students who are currently being educated is already in demand. This is just one of several factors that will make closer cooperation between academia and industry increasingly important in the future.</div> <div>Head of Area of Advance Sinisa Krajnovic ended the day with a story about his friend, retired truck driver Peter. Peter worked alone and was often away on long tours. He had a difficult time finding a replacement if he fell ill, and sometimes he had to wait several days for spare parts on site in Europe. Over the years, he lost a lot of time that could have been spent with his family. But future truck drivers will work differently, Krajnovic said:</div> <div>“The trucks will be in a plutoon, and the driver in the first truck will be the only one actually driving. The others can spend the time on other things, like skype calls to the family. Or they can even sit at home and drive their trucks remotely.”</div> <div>The participants seemed content as they left Chalmers’ conference hall Runan. Next year, it is time again for an Initiative seminar.

Tell us a bit about the arrangement!</strong></span><div>&quot;We will start the day with a master class session, where some of Chalmers' own researchers, leading in their respective fields, give lectures about their research linked to the theme of circular economics. We want to give a broad perspective on the concept, ranging from business models, materials, product development to future civil society. The first talk of the day will be held by an invited speaker who can give a broad understanding and background to the theme.&quot;</div> <div><br /></div> <div><strong>Circular economy - how would you describe it?</strong></div> <div>&quot;Oh, there are many descriptions of it. To me it is about being able to dare to change from linear to circular business models. To achieve true sustainability, we not only need to change our technical conditions, but also the ways we consume. Everything has to be linked, from business value for those who produce and deliver products and services, to the actual customer benefit.&quot;</div> <div><br /></div> <div><strong>What do you hope Chalmers Sustainability Day will bring?</strong></div> <div>&quot;I want more people to be inspired and take circular economics into account in their research, in a wider sense than today. Chalmers vision to make the future more sustainable is reinforced by paying attention to all research internally. I hope this will create awareness of ongoing activities, so that synergies are found in various research areas.&quot;</div> <div><br /></div> <div><strong>Is it still time to propose something for the programme?</strong></div> <div>&quot;We have closed the agenda for the master class session but there are still a few slots open in the afternoon progamme. If you have a suggestion – talk to us! We hope for a greater participation of researchers and teachers this year. A possibility that not so many have reacted to is the poster exhibition. We would like to see more proposals here!&quot;</div> <div><br /></div> <div><strong>The collaboration with the Student Sustainability Week Act! Sustainable is new this year! How will they contribute? </strong></div> <div>&quot;Above all, they can contribute with their perspective. The students have high demands on Chalmers as a university to work more with sustainability internally, but they also push to steer their education towards the circular perspective. We hope many students will show up and be able to take part in research and be inspired to make their own circular choices in the future.&quot;</div> <div><br /></div> <div><br /></div> <div><br /></div> <div><div><b><img src="/SiteCollectionImages/Areas%20of%20Advance/Production/750x340_Lars-Nyborg_SDG12.jpg" alt="Picture of Lars Nyborg, director of Production Area of Advance" style="margin:5px;width:680px;height:312px" /></b><br /><br /><span></span><em>This year's theme is broad and embraces much of the research within the Areas of Advance, says Lars Nyborg, Director for Production Area of Advance and the organizer 2019 for Sustainability Day.

Why the choice of circular economy as a theme?</b></div> <div></div> <div>- We chose to focus on circular economics, as it is a theme that unites many of Chalmers Areas of Advance. The solutions of the future lie in how we implement circularity in society and here we have an opportunity to discuss it thoroughly. The theme can work both for big issues and in the small perspective as an individual citizen. We believe the theme can inspire and provide new knowledge for everyone - students, researchers and other staff at Chalmers.</div> <div><br /></div> <div><strong> What does circular economy mean to you?</strong></div> <div>- It's a quite difficult concept and theme. There is not only one answer, but many. I would like to compare the concept of circular economy to an umbrella, under which several different contexts and definitions can be gathered.</div> <div><br /></div> <div><strong>What do you hope visitors will bring home from the event? </strong></div> <div>- I hope for increased commitment and an understanding of what circular economics is. I also wish for a broadened understanding that a sustainable future is a matter of creating solutions. I would also be interesting if the discussions include a questioning attitude regarding suggested solutions. A sharper dialogue and debate are important for showing a sustainable way forward. Here, Chalmers can really contribute.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Production/SDG-9-11-12.jpg" alt="Picture of the logos of sustainable goals 9, 11 and 12" style="margin:5px;width:690px;height:345px" /><br /><br /><br /></div> <div><strong>FACTS:</strong></div> <div>Chalmers Sustainability Day takes place on 8 November at the Chalmers Conference center.

The question is relevant not only to humans but also to self-driving cars that must be confident about their own position. Researchers at Chalmers University of Technology are developing smart algorithms for so-called visual localisation based on machine learning of large amounts of data collected from photos.</b></p>​<img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smart%20bildteknik%20bygger%20artificiellt%20lokalsinne/FredrikKahl_250x300px.jpg" class="chalmersPosition-FloatRight" alt="Fredrik Kahl" style="margin:5px" /><span style="background-color:initial">“Visual localisation means that a robot or car should be able to determine its current position using camera images that are compared to a map of the surroundings”, says Fredrik Kahl, professor of computer vision and image analysis at the department of Electrical Engineering at Chalmers. &quot;It is about identifying distinct features and comparing them to already known characteristics in the surroundings, which are positioned on a three-dimensional map.&quot;</span><div><br /><span style="background-color:initial"></span><div>Of the methods currently available to determine your position, camera is the most promising in this context.</div> <div><br /></div> <div>”Camera technology is comparatively cheap and provides access to a lot of information”, Fredrik Kahl continues. “There are several possible applications for the technology, where self-driving cars and unmanned vehicles probably are the most prevalent. Research is also underway in areas such as smart camera technology used in mobile phone navigation apps, in industrial production processes and in flexible systems for inspection of various environments.”</div> <div><br /></div> <div>One example, where the technology is now being demonstrated in a supermarket setting for later transfer to other applications, is the research project ‘Semantic Mapping and Visual Navigation for Smart Robots’, funded by the Swedish Foundation for Strategic Research. The project is headed by Fredrik Kahl and involves researchers from Chalmers and Lund University among others.</div> <div><br /></div> <div>”Semantic mapping means training the system to be able to recognise named physical objects in pictures and link them to a geographical position”, Fredrik Kahl says. “In the supermarket setting, the system first gets to learn how selected products look like and what they are called, and then it should be able to register where these products are located on the shelves in the store. To fulfill the task, various subsystems in machine learning, computer vision and robotics need to work together.”</div> <div><br /></div> <div>This technology will be tested in a supermarket in Stockholm, where a drone will fly along the shelves to identify which and how many products of each kind that are in stock. One challenge is that the products on the shelves can block each other.</div> <div><br /></div> <div>There are significantly more difficulties to overcome when transferring this technology outdoors and incorporating it into a self-driving car. Then, factors such as weather, daylight and time of the year also need to be considered.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smart%20bildteknik%20bygger%20artificiellt%20lokalsinne/kamerabilder_750px.jpg" class="chalmersPosition-FloatLeft" alt="camera images" style="margin:5px" /><br /><br /><br /></div> <div><br /></div> <div>“A picture taken on a beautiful summer day differs quite a lot from a picture taken at the same place on a wintry evening in January”, says Fredrik Kahl. “Without leaves on bushes and trees, the view can be completely changed, and other objects appear in the picture instead. Fog, snow and rain, in turn, are blurring the recognition marks.”</div> <div><br /></div> <div>Therefore, in order to build the visual localisation system, you need to have access to many photos taken under different exterior circumstances from the same geographical location.</div> <div><br /></div> <div>The researchers are putting labels, annotations, for various types of phenomena on the images that they want the system to recognise, such as ‘road’, ‘pavement’, ‘building’ etc. Often, subdivisions are needed for the annotations to be useful, for example ‘vegetation’ becomes a too comprehensive label. Annotations are needed, but the work is time-consuming, and it is therefore important to find a balanced level for the number of classifications. </div> <div><br /></div> <div>Machine learning in artificial neural networks is used to train the system, bit by bit improving the ability of the self-driving car or robot to recognise the surroundings and to orient itself.</div> <div><br /></div> <div>”As our algorithms become more accurate and the three-dimensional map is being built up, fewer images will be needed for the system to be able to locate itself”, Fredrik Kahl says. “A lot of tricky problems still remain to be solved, but that is what makes this field so exciting and fun to work with.”</div> <div><br /></div> <div><strong>Website to test the accuracy of the localisation</strong></div> <div>The Chalmers researchers have launched a website, that up till now contains more than 100 000 collected images. On the website, like-minded research teams can compare and test the accuracy of their algorithms by downloading images, performing calculations and then uploading their results to get them corrected and ranked on a top list.</div> <div><a href="https://www.visuallocalization.net/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />To the website Long-term Visual Localisation ​</a><br /></div> <div><br /></div> <div><div>Text: Yvonne Jonsson</div> <div>Photo of Fredrik Kahl: Malin Ulfvarson​</div></div> <div><br /></div> <div><strong>More about the research and researchers</strong></div> <div>The research team behind the research and the film &quot;Localization using semantics&quot;: Måns Larsson, Lars Hammarstrand, Erik Stenborg, Carl Toft, Torsten Sattler and Fredrik Kahl</div> <div><span style="background-color:initial">The research team behind the project <a href="https://research.chalmers.se/en/project/?id=7658">Semantic Mapping and Visual Navigation for Smart Robots</a>, and the film from the supermarket: Patrik Persson, Marcus Greiff, Sebastian Hanér, Olof Enqvist and Fredrik Kahl</span></div> <div><br /></div> <div><strong>For more information contact</strong></div> <div><a href="/en/Staff/Pages/fredrik-kahl.aspx">Fredrik Kahl</a>, professor of computer vision and image analysis at the department of Electrical Engineering at Chalmers University of Technology</div> <div><a href="mailto:%20fredrik.kahl@chalmers.se">fredrik.kahl@chalmers.se </a></div> <div><br /></div> </div>Tue, 24 Sep 2019 00:00:00 +0200https://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Self-driving-cars-increase-safety-but-require-trust.aspxhttps://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Self-driving-cars-increase-safety-but-require-trust.aspxSelf-driving cars increase safety but require trust<p><b>​In just ten years, self-driving cars could make traffic both safer and more environmentally friendly. But lack of legislation and trust can put this development at a halt, says Professor Erik Ström at Chalmers.</b></p>​<span style="background-color:initial">Heavy traffic of autonomous vehicles driving at a very close range. It might be hard to grasp that this future scenario – which is actually not very distant – equals enhanced traffic safety and lower emissions. But it does, says Erik Ström, professor at the Department of Electrical Engineering at Chalmers University of Technology, who is attending Chalmers’ seminar on future transport next week.</span><div><img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_bilder-utan-fast-format/Erik-Strom_profile-picture.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 10px;width:200px;height:264px" /><div><br /></div> <div>“When we share data, certain types of accidents are reduced; in the long run there should be no accidents at all. The efficient driving also reduces fuel consumption and exhaust emissions. In addition, we can make better use of the roads, driving closer together and in narrower lanes. This is a huge benefit as construction of new roads is expensive and has a major environmental impact.”</div> <div><br /></div> <div>The technology of self-driving cars has come a long way. Erik Ström describes autonomous driving as a step-by-step process, where step one is manual driving and step five is completely self-driving cars. Many cars already have, for example, cruise control, warning signals if the car departs from the lane, or automatic braking if you come to close to the car in front of you. But the implementation of the technology depends on other factors, such as commercial interests and legislation.</div> <div><br /></div> <div>“If an accident were to occur: Who is responsible? Are you responsible, sitting in your car even though you are not driving? Or is it the car manufacturer, or the provider of data sharing technology?” says Erik Ström.<br /></div> <div>“Trust is also an issue. Car manufacturers have to rely on each other in order to share data. And the public need to trust the technology.”</div> <div><br /></div> <div>For example: In order for us to trust the autonomous cars, communication between cars and pedestrians is necessary. Today, a person crossing the street makes eye contact with the driver, and a nod or gesture indicates that it’s safe to pass. But what will happen in the future? Most likely, the cars need to be able to “wink” or “smile” to show that the pedestrian is registered.</div> <div><br /></div> <div>Also, there is the question of privacy. How will the large amounts of data be handled, without compromising personal privacy? And how do you protect the system from being hacked?</div> <div><br /></div> <div>“There is always a risk of hacking, but we can make it difficult enough to not be worth the trouble. We have to balance benefits and risks. It’s like the Internet; being online always entail the risk of hacking, but to most of us it’s worth the risk,” says Erik Ström, adding that it’s still unclear who should pick up the bill of data security.</div> <div><br /></div> <div>The self-driving cars will probably run slower than cars today. But it doesn’t matter. We will still arrive faster, as cars can interact better on the roads. And:</div> <div><br /></div> <div>“You don't have to spend time parking. You will be able to step out of the car at your destination, and the car will park itself,” says Erik Ström.</div> <div><br /></div> <div>Note: <a href="/en/areas-of-advance/Transport/calendar/initiative-seminar-2019/Pages/default.aspx">Chalmers Area of Advance Transport organises the Initiative seminar Transportation in the Age of Digitalisation on September 26.

A study from Chalmers now shows that the new system reduces fatigue and pain in drivers.</b></p>​<br /><span style="background-color:initial">Heavy steering is a recurring problem among heavy vehicles and buses, and can cause the drivers discomfort and pain in shoulders and arms. In the summer of 2017, Volvo Dynamic Steering (VDS) was installed in the electric buses on route 55 in Gothenburg. The result of a long-term study done in conjunction with this now clearly shows that work-related physical problems can be reduced with the help of the new system, which is a further developed, advanced power assisted steering.</span><div><br /><span style="background-color:initial"></span><div>The study was done by Chalmers researchers and conducted over 1.5 years. It shows that the drivers who reported moderate to very severe problems prior to the study, either experienced a reduction to weak or no pain, or did not experience any increase in symptoms when driving with VDS.</div> <div>“It is clear that VDS has had a positive impact on the bus drivers' work environment,” says researcher Lars-Ola Bligård at the Department of Industrial and Materials Science, and continues:</div> <div>“We investigated how bus drivers’ perceived physical problems were affected over time. We conducted a survey study over 1.5 years and supplemented the surveys with interviews. On average, 14 drivers participated in each of the four survey rounds, and six of the drivers could be followed across all four surveys. In their answers, the drivers estimated how much symptoms they experienced in different body parts.”</div> <div><br /> </div> <div>Volvo Dynamic Steering removes vibrations and thrusts that otherwise propagate through the steering wheel. At the same time, maneuvering in confined spaces is facilitated, as steering wheel resistance is reduced by up to 70 percent at low speeds. The steering wheel also automatically returns to its original position when the grip is relieved.</div> <div><br /> </div> <div>In general, the drivers are very positive about VDS.</div> <div>“To drive a bus in a safe way, on time and in a difficult traffic situation, the bus driver profession makes for a sometimes stressful work environment. Solutions such as Volvo Dynamic Steering are a welcome and important development for our drivers to get a better working environment,” says Karl Orton, IT and fleet director at Keolis, the operator of route 55.</div> <div>The results of the study now open for further research, and Lars-Ola Bligård says:</div> <div>“It would be good to further clarify the validity of the relationship between VDS and reduced symptoms, as there were quite few participants in this study. It would also be interesting to study whether drivers who drive a lot with VDS develop fewer and less serious physical problems than drivers who do not drive with this new steering system.”</div> <div><br /> </div> <div>Text: Mia Malmstedt / Olof Nordangård</div> <div>Photo: Tina Koohnavard</div> <div><br /> </div> </div>Wed, 28 Aug 2019 16:00:00 +0200https://www.chalmers.se/en/departments/m2/news/Pages/European-railway-harmony-better-for-the-climate.aspxhttps://www.chalmers.se/en/departments/m2/news/Pages/European-railway-harmony-better-for-the-climate.aspxEuropean railway harmony is better for the climate<p><b>​Transporting goods by train instead of by truck is one of the keys to more sustainable transports within Europe. But the transition to rail is difficult, and one major problem is that alarm limit values for wheel loads are not coordinated between European countries. But thanks to researchers at Chalmers, new European rules have been introduced that will make it easier to transport goods by train.</b></p><p>“Our research was the scientific basis that convinced the rest of Europe to adapt to our Swedish proposal for alarm limit levels. The alternative for us in Sweden would have been the continuing lack of clarity on the matter. This would most likely have diminished our competitiveness for goods by rail”, says Anders Ekberg, professor at the Department of Mechanics and Maritime Sciences and director of Charmec*.</p> <h2 class="chalmersElement-H2">More environmentally friendly transports</h2> <p>To achieve the overall climate targets, one of Sweden’s milestones is to double the share of goods transported by train by the year 2030. If that amplification is to become a reality, three important measures are needed – to increase both the operational safety as well as the capacity of the railway and to promote cross-border freight traffic ¬– something that today is difficult because alarm limit values for rail loads vary widely between countries in Europe.</p> <p>About half of the freight traffic in Europe is already crossing borders and that trend is expected to increase as the European freight corridors are gradually put into operation. This measure is necessary to enable railway freight to compete with freight on the road.</p> <p>The lack of coordinated alarm limits means that a damaged wheel can produce wheel load magnitudes that are allowed in one country, but not in another. For example, a Swedish train can travel through Europe just to have to turn around at the border of Switzerland, which today has the lowest permissible level, something that has occurred. This type of inefficient management of alarm levels also has consequences for passenger traffic as operational disruptions spread in the rail system – which leads to high costs for both railway managers and train operators in addition to the nuisance it causes to passengers.</p> <h2 class="chalmersElement-H2">Sensitive system</h2> <p>The railroad is an interlinked system where the “weakest link” often dictates how the system can be used to transport goods. Other modes of freight transport can operate at higher levels of interference. It is easier to quickly redirect a truck when there are obstacles on the road than to redirect a train that often only has one way to go. For this reason rail traffic needs to put more efforts into avoiding interferences. Having the same alarm limits in all European countries is a step towards avoiding disturbances.</p> <p>“To be able to agree on common alarm limits, a solid, scientific basis is required. At the heart of the now common alarm limits is our research of forces from out-of-round wheels and how these affect the risk of rail breaks and disruptions​. The work has now also been accepted and established internationally in a so-called International Railway Solution (IRS) which the International Railway Union (UIC) has approved. Of course, we are very pleased with that”, says Anders Ekberg.</p> <div><br /></div> <p>* <em>Charmec (Chalmers Railway Mechanics) is a national centre in the field of railway mechanics with twelve business and administration stakeholders.

The symposium highlights what is at the forefront when it comes to research in vehicle dynamics both on rail and road&quot;, says Bengt Jacobson, professor of vehicle dynamics at Chalmers.</div> <div><br /></div> <div>Hosts for the symposium are the Department of Mechanics and Maritime Sciences at Chalmers as well as the Chalmers Railway Mechanics (Charmec) and the Vehicle and Traffic Safety Center at Chalmers (Safer) with the support of the Transport area of advance at Chalmers.</div> <div><br /></div> <div>* <em>IAVSD is an abbreviation for the International Association for Vehicle System Dynamics, which is an organization that works to develop vehicle dynamics.</em></div></div> <div> </div> <h3 class="chalmersElement-H3">Read more:</h3> <div><div><a href="https://iavsd2019.se/">IAVSD2019</a></div> <div><a href="http://www.charmec.chalmers.se/">Charmec</a></div> <div><a href="https://www.saferresearch.com/">Safer</a></div> <div><br /></div> <div>Text: Anders Ryttarson Törneholm<a href="https://www.saferresearch.com/">​</a></div></div> <h3 class="chalmersElement-H3"> </h3>Tue, 13 Aug 2019 00:00:00 +0200https://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Broad-approach-with-theme-projects.aspxhttps://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Broad-approach-with-theme-projects.aspxBroad approach with theme projects<p><b>​A total of 28 applications were sent in as Transport Area of Advance’s made a call for theme projects. Of these, 19 were granted support. &quot;Very successful&quot;, says Kajsa Hulthén, Co-Director of the Area of Advance.</b></p>​<span style="background-color:initial">Early this spring, the Transport Area of Advance announced two calls: one for one-year projects in the fields of Electromobility and Autonomous transport, and one for two-year projects within Transition to the transport system of the future.</span><div>“With these calls, we wanted to encourage new interdisciplinary collaborations,” says Kajsa Hulthén.</div> <div><br /></div> <div>To nurture interdisciplinary collaborations lies in the nature of the Area of Advances. And the result was successful, she says:</div> <div>“It’s amazing to see that the research projects span a very wide range – from technology oriented to projects more oriented to social science – and gather researchers from 7 of Chalmers’ 13 departments. We also note that people who have never worked together before, will now do so in these projects.”</div> <div><br /></div> <div><strong>Logistics, ferries and e-commerce</strong></div> <div><br /></div> <div>The projects focus on, for example, electric ferries, obstacles and opportunities in the implementation of self-driving vehicles, new gearbox technology in electric cars, safety for electric bicycles you rent on the streets, environmental impact of coastal boats, integration of transport and electrical systems, the introduction of automated logistics systems, challenges in getting people to share vehicles, segregation due to growing e-commerce, lack of materials for future cars – and much, much more.</div> <div><br /></div> <div>Incoming projects were evaluated by three persons from each profile area within the Area of Advance – Sustainable Vehicle Technologies, Transport Efficiency and Customer Adapted Logistics, Traffic Safety – including the profile leaders. Based on this evaluation, decisions were then made by the management team of the Transport Area of Advance.</div> <div><br /></div> <div><strong>Four criteria for assessment</strong></div> <div><br /></div> <div>The assessments were made on the basis of four criteria: the contribution of the project to the Area of Advance Transport’s vision – for example regarding expected benefits, possibilities to promote research collaborations, or potential for obtaining future external funding – how the project relates to the thematic areas, the addition to the research area made by collaborations between researchers, and the clarity of the interdisciplinary aspect.</div> <div>“Although there’s a big difference in project scopes, the assessment group had a relatively large consensus on which projects to fund,” says Kajsa Hulthén.</div> <div><br /></div> <div>The projects will be made available on the website research.chalmers.se, and followed up through a mid-term and a final report.</div> <div>“We also hope to take part of some interesting results along the way, as the researchers present their work on various events arranged by the Area of Advance, such as lunch seminars, our “alla-forskar-dagar” and Initiative seminars,” Kajsa Hulthén concludes.</div> <div><br /></div> <div>Text: Mia Malmstedt</div> <div>Picture: Boid</div> <div><br /></div>Thu, 27 Jun 2019 09:00:00 +0200
