That was the result when Chalmers researchers asked passengers on the electric bus route 55 to design an indoor stop where people want to stay.</b></p><img src="/sv/styrkeomraden/transport/nyheter/PublishingImages/PontusWallgren_250px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />At the bus stop at Lindholmen, the bus waits indoors. The <span>quiet and emission-free<span style="display:inline-block"></span></span> electric drive of bus 55 allows the stop to be placed in the middle of a calm and clean environment.<br /><br />&quot;The original plan for the indoor bus stop back in 2015 was to create a place where you want to stay on for a while, to study or meet with friends<span>&quot;<span style="display:inline-block"></span></span>, says Pontus Wallgren, researcher in industrial and material science at Chalmers. &quot;However, when we interviewed passengers it turned out that although the stop is popular, not many people stay there.&quot;<br /><br />This is why a group of passengers were asked to contribute to the further development of the indoor stop, in collaboration with the researchers and the <span>partners <span style="display:inline-block"> in the  </span></span>ElectriCity project .<br /><br /><img src="/sv/styrkeomraden/transport/nyheter/PublishingImages/workshopdeltagare_inomhushållplats.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />&quot;The participants all agreed that they wanted to make the stop more like a living room and less like a garage, and with lots of green plants&quot;, says Pontus Wallgren. Furniture and plants ordered, the passengers can soon start enjoying their new living room.<br /><br />The facelift of the bus stop is part of a study that investigates how drivers and passengers experience the electric buses and the bus stops. According to Pontus Wallgren, both buses and stops received high marks. Among other things, the buses are considered well adapted for persons with reduced mobility, and easy to drive smoothly and comfortably.<br /><br />The time required for charging at end stops is a challenge for public transport planners. Route 55 is relatively short, about 25 minutes, and the buses need to charge for three to four minutes. However, the timetable has a margin of ten minutes between the trips.<br /><br />&quot;The drivers see the break as an advantage. They say it reduces stress and back pain and makes them more alert while driving&quot;, concludes Pontus Wallgren.<br /><br />The results of the study will be presented at a seminar at Chalmers on January 24, 2018. <a href="/en/departments/ims/calendar/Pages/EBSF_2-Gothenburg-demo-showcase.aspx">Sign up here &gt;&gt;</a><br /><br /><strong>FACTS ABOUT THE STUDY</strong><br />The study is part of <a href="">European Bus System of the Future 2</a>, a project led by the <a href="">International Association of Public Transport</a> and partly financed by the EU Horizon 2020 program.<br />The study was conducted by Pontus Wallgren, Oskar Rexfelt, Victor Bergh Alvergren, MariAnne Karlsson and Erik Ohlson, Chalmers.<br /><em>Contact</em>: Pontus Wallgren, +46 31 772 13 97, <a href=""></a><br /><br /><strong>FACTS ABOUT ELECTRICITY</strong><br /><a href="">ElectriCity</a> has run in Gothenburg since 2015 and is a collaboration between industry, academia and society where the participants develop and test solutions for tomorrow's sustainable public transport.

Director Sinisa Krajnovic reflects on what 2017 meant for Area of Advance Transport.</b></p>​<img src="/sv/styrkeomraden/transport/nyheter/PublishingImages/SinisaKrajnovic-inomhus_250x300px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />I hope you have had a well-deserved rest during the holidays. During my leave, I have had the opportunity to reflect on what we have achieved in 2017, and I feel proud that we have accomplished a great deal in transport research and utilization.<br /><br />Much effort has been made to create a better model for interdisciplinary transport research within the Area of Advance Transport. This has led to our thematic areas - Electromobility, Autonomous transportation and the Transition to future transport systems. I think they are a good way of working with transport challenges across disciplinary or institutional boundaries and for Chalmers and University of Gothenburg to collaborate.<br /><br />Another major activity has been to build international partnerships with a few selected universities in the world that can complement us and strengthen our research, utilization and education. This has already led to two strategic partnerships, one in the United States and one in Belgium, and the management group is now working to create a similar partnership in China. These partnerships are carefully selected to complement our resources and competencies. At the same time we expand our existing partnerships across disciplines, and our industrial partnerships or training programs. Our hope is that the effects of these partnerships will soon be felt in the form of new opportunities for exchange of researchers and students, joint workshops and conferences, opportunities for research and education with shared resources and joint research projects.<br /><br />Since the start of the Areas of Advance, Transport has focused on getting new young researchers at Chalmers through postdoc funding. In 2017 we continued this initiative with 17 new researchers in interdisciplinary transport projects.<br /><br />We have arranged a highly appreciated initiative seminar, and received a lot of appreciation for engaging academy, industry and public authorities in the question of the transition to future transport systems. Of course, this is to a great extent thanks to the quality of the research we do at Chalmers and University of Gothenburg. It is important that we strengthen this cooperation even more with joint projects and common working methods in order to get the best effects.<br /><br />No one has probably missed Chalmers's review of the Areas of Advance, and I am pleased that the investigation has shown that the Area of Advance Transport is functioning well, is considered important and will continue without major changes.<br /><br />Now by the end of January, I notice that the gray days begin to get brighter and there is a lot going on in the transport area. We have already begun planning for our research days, lunch seminars and initiative seminars and I hope we will soon meet at one of these activities.<br /><br /><br /><br /><br />Wed, 10 Jan 2018 00:00:00 +0100 thesis could make a more fuel efficient aircraft possible<p><b>Lowering of fuel consumption and emissions is of paramount importance in the aerospace industry but the aircraft engine is a complex system. The different parts are dependent on each other and it’s difficult to determine which component to take care of first and foremost to make the aircraft engine more efficient. Oskar Thulin deals with this in his PhD thesis ”On the analysis of energy efficient aircraft engines”</b></p><div><div>The aircraft engine consists of many integral components and each component will influence the overall performance of the system. Furthermore, the aircraft engine has weight and contributes to drag that must be compensated for by the engine. Using the regular way to assess performance, it is impossible to compare one component's loss to another or to directly relate an individual component's loss to the overall loss. Oskar Thulin has developed an analytical method that makes it possible to directly compare component losses in a system perspective. The method also makes it possible to include weight or caused drag in the analysis.</div> <div><br /></div> <div>&quot;This gives a much more clear picture of how big the losses are for the various components, as well as for each component type&quot; says Oskar Thulin.</div> <div><br /></div> <div>The developed framework is used to study various aircraft engines. In general, it can be said that the hot exhaust gases that leave the engine, the combustion process in itself, and the part of the kinetic energy in the exhaust that is not used to propel the aircraft forward, are the main sources of the overall loss.</div> <div><br /></div> <div>&quot;Based on the analysis you can discuss different technologies that can do something about these dominant losses. This enables a future more fuel-efficient airplane, says Oskar Thulin, who will present his PhD thesis at Chalmers University of Technology<a href="/en/departments/m2/calendar/Pages/On-the-analysis-of-energy-efficient-aircraft-engines.aspx"> on December 6 at 10:00 in HB4. </a></div></div> <div>​<br /></div> Fri, 01 Dec 2017 15:00:00 +0100 study: Chalmers a top maritime university<p><b>The maritime education and research provided at Chalmers University of Technology is of the highest international standard, according to the first global study undertaken in the field.  ​</b></p>​<span style="background-color:initial">This comes as no surprise to those in the division of Maritime Studies on Campus Lindholmen at Chalmers University of Technology. </span><div><br /><span style="background-color:initial"></span><div>“We’ve always hoped and believed that we would be placed high on the list and this is our confirmation. In Sweden we have long had high-quality maritime education and training, and our sailors have a reputation for competence. Over the past ten years we have also worked hard to further develop and improve the quality of the educational programmes,” says Fredrik Olindersson, Head of the Division for Maritime Studies at Chalmers.</div> <div><br /></div> <div><a href="">The International Association of Maritime Universities (IAMU) </a>, an organisation whose members include more than sixty of the most prominent universities in the field, is behind the study. Chalmers was elected to IAMU in 2016.</div> <div><br /></div> <div>“It took over a year to become a member. You have to send in masses of documents, and they carry out site visits to make sure you live up to their high standards. Not just anyone can join. At the last Annual Meeting a couple of new universities joined, but several also applied and were not accepted,” Olindersson says. </div> <div><br /></div> <div>The study is intended to give IAMU’s member universities an idea of where their strengths lie and what they could develop. So the organisation does not provide traditional rankings but confines itself to listing, in alphabetical order, the universities that fall in the upper quartile (top 25%) in the three areas studied. </div> <div>“Chalmers University of Technology came out top in all the areas studied – global exchange, strength of research and quality of education. What is most striking about the study is that Chalmers is the most well-balanced university. That is Chalmers’ strength and one that should be nurtured and further developed,” says Takeshi Nakazawa, Executive Director of IAMU.</div> <div><br /></div> <div>Olindersson explains that Chalmers is often used as a model for a maritime educational institution around the world and that is why there are so many international visits to Chalmers. </div> <div><br /></div> <div>So what is the strength of maritime education and training in Gothenburg?</div> <div><br /></div> <div>“In addition to having competent teachers, we are one of the few educational institutions which invests a great deal in simulator education and in the work of simulator instructors. We want to maximise the impact of the expensive time spent in the simulator that forms part of the training.”</div> <div><br /></div> <div>According to Olindersson, Chalmers University of Technology is far ahead of most others in the world in its educational work on sustainability and the environment. All maritime training in the world complies with the International Convention on Standards of Training, Certification, and Watchkeeping for Seafarers (STCW) which governs the minimum standards of training, but like other IAMU members, Chalmers offers education and training at a significantly higher level.</div> <div><br /></div> <div>“The Heads of Programmes have continuously extended the programmes and have placed much greater emphasis on leadership, communication, critical thinking, and sustainability. To improve the eligibility of students, and their employability in the long term, we have also introduced a number of elective courses to the programmes. On the Master Mariner programme, students can choose to specialize in passenger and cruise ships, tanker shipping or the offshore sector. The Marine Engineer programme now includes a high voltage element, and there are elective courses in advanced ship operations, marine risks, and marine ergonomics.”</div> <div><br /></div> <div>On the research side, maritime environmental sciences, maritime human factors and marine technology are strong Chalmers areas. Read more about Maritime Studies here.</div> <div><br /></div> <div>“Global exchange mainly involves student and teacher exchanges, where we’ve increased the options in recent years by teaching the final year in English. What sets us apart is that many other universities don’t do this. However, we’ve got several exchange agreements that are working well and another couple is under way that will hopefully lead to more exchanges,” Olindersson says.</div> <div><br /></div> <div><strong>Swedish simulator centre for shipping</strong></div> <div>Campus Lindholmen houses <a href="/en/departments/m2/simulator-labs/simulators/Pages/default.aspx">Sweden’s most extensive simulator centre for education and research in shipping</a>.

During the past 10-15 years his research has increasingly focused on urban freight and logistics.<br /><br />“Most of my research has considered the interaction between public policies and business decisions”, he says. “I am particularly interested in the way that research can influence public policy and organizational behavior.”<br /><br />As profile coordinator Michael Browne wants to play a part in continuing and extending the collaboration between University of Gothenburg and Chalmers building on the work of Dan Andersson, previous profile coordinator. He points out that there are already many areas where the two universities collaborate very well, and takes autonomous transport as an example of a field where technology, engineering and social sciences benefit from working together.<br /><br />“The transition to future transport provides many challenges and is an opportunity for researchers to work together on providing insights and potential solutions”, he says. “Combining our expertise in fields including psychology, geography, urban form, technology developments and logistics opens many possibilities.” <br /><br />Sinisa Krajnovic, Director of Area of Advance Transport, welcomes the strengthened connection between the universities. <br /><br />“Chalmers and University of Gothenburg need to increase their cooperation in the field of transport in order to meet the interdisciplinary challenges of society and industry.

Like many other fluids, engine oil becomes thicker at low temperatures. This also leads to a significant increase of the unwanted engine friction and makes the engine consume more fuel when cold. Thermal engine encapsulation is a combination of shells, mounted around the engine, that insulate it from the cold environment and keep it warm for a long time after we turn it off. This way it is more likely that the engine will be warm and efficient next time we start it. </div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">To design an engine encapsulation is a complex engineering task, which requires knowledge of the energy transport through the entire powertrain of the vehicle. Blago Minovski has applied an effective way to calculate the variation of the temperatures of the parts and the oil in the engine after we turn it off. This is central for the correct prediction of the potential benefits from encapsulating the engine.</span></div> <div><span style="background-color:initial"> </span></div> <div>- Every gram of fuel that we can avoid burning for transportation reduces our environmental footprint. Thermal engine encapsulation is a technical solution which offers a step in this direction.

The one who finds the smartest method to quickly verify a system becomes highly sought after. Carl-Johan Seger is one of those people.</b></p>​ <br />In 1995, Carl-Johan Seger received a phone call with an offer that would change the direction of his research career at the University of British Columbia. He had only a few days earlier taken up a professor's appointment with so-called tenure, a meriting position.<br />&quot;I started my new position in June 1995 and in September I resigned,&quot; says Carl-Johan Seger, laughing at the memory.<br /><br />The phone call came from the American semiconductor company Intel, who was in great need of his skills.<br />&quot;There was a crisis at Intel. They had just rolled out a new generation of Pentium processors when a serious error in the construction was discovered. The error had escaped Intel's very extensive verification procedures. The final bill landed somewhere in the neighbourhood of 475 million dollar&quot;, he says.<br /><br />The problem was that the traditional verification method did not allow testing of all conceivable values, it could simply not be done within the time frame, even though very extensive verification was carried out.<br /><br /><strong>Mathematical tools for verification</strong><br />Carl-Johan Seger's research is on formal methods, i.e., mathematical tools for analysis and verification of systems. Very useful for verifying hardware – in this case silicon circuits. The tools that Carl-Johan Seger worked with in his research could offer the solution to the precise problems that Intel suffered.<br /><br />&quot;With formal methods, we developed a verification tool that was not only more reliable, we could also perform the verification faster.&quot;<br /><br />As a result, Carl-Johan Seger introduced early formal verification in the development process at Intel. <br />&quot;Early formal verification is extremely important for achieving good results. It is only after we verify that we can know for sure, and can draw conclusions from the work. It is usually said that we learn by our mistakes, and I couldn’t agree more.&quot;<br /><br />At Intel, he created the Forte Formal Verification System, based on his previous research, and the same verification system is still used today, over 20 years later.<br />&quot;If you buy a computer today with an Intel processor, large parts of the processor are verified by this method.&quot;<br /><br /><strong>Return to academia</strong><br />He stayed at Intel for 22 years, and during that time he has published his research with great impact.<br />&quot;It has been fun working in industry, but there is not much long-term research done. In 2006-2007, I was given the opportunity to be a visiting researcher at Oxford&quot;, he says. <br /><br />Perhaps that is where the thoughts of returning to academia took shape? So, when Intel last year announced staff cuts, and launched a retirement package, he took the offer.<br />&quot;Intel's offer turned to those who with x number of years in the company, added with one's own age, summed to the number 75 or higher. And it included me with a 3-month margin.&quot;<br /><br />Carl-Johan Seger is pleased with his choice to return to academia and Chalmers, and the mood is on top during the interview. We wonder, of course, how he experiences the transition.<br />&quot;It's a big change, I cannot say it's neither better nor worse, but on the other hand – it takes a lot of effort and renewal and it makes me feel younger.&quot;<br /><br /><strong>Important part of autonomous systems</strong><br />Carl-Johan Seger is recruited as part of Chalmers activities in the Wallenberg project WASP – <a href="/en/areas-of-advance/ict/research/automated-society/wasp/Pages/default.aspx">Wallenberg Autonomous Systems and Software Program</a>. An important trend along with the development of autonomous systems is the decreasing gaps between hardware and software, we are seeing much more of programmable hardware. There are two very big benefits to doing so – increased performance and reduced energy consumption.<br /><br />&quot;When a large number of sensors are introduced to enable an autonomous system, and all sensors are sending their data to a central processor, it becomes inefficient and slow. Through programmable hardware, or FPGA, Field-Programmable Gate Array, we can introduce more intelligence closer to the sensors&quot;, says Carl-Johan Seger.<br /><br />FPGA are circuits in which the function of the circuit is determined by software. It provides flexibility, you do not necessarily need to re-design your hardware to introduce new functionality – just rolling out new instructions is enough. But there's a big challenge, it gets a lot more difficult to design and verify.<br />&quot;Look at cars for example, they contain many computer-powered features, and it's crucial that the systems respond quickly, never fail and are secured. This is what we are testing using formal methods&quot;, says Carl-Johan Seger. <br /><br />So, what does Carl-Johan Seger think about the future of self-driving vehicles out of a safety perspective? He says that there are several layers of technology in the vehicles – all are not critical systems.<br />&quot;There is a core in the systems that we need to find solutions for, in order for the self-driving vehicles to succeed. The future is about robust technology, but it's also about working out the regulations and what the consequences are if anything goes wrong. The market will determine how big risks that are reasonable to take. If the cost of errors becomes too large then we will not see any self-driving vehicles on the roads.&quot;<br /><br />Carl-Johan Seger points out that autonomous systems are not just about vehicles. We will see all sorts of new services, inspections, deliveries, window cleaning, and a host of applications in industry.<br />&quot;The development of autonomous systems leads to an increasing need to do right from the start – and thus it gets more and more important with verification. It is simply faster and less of a business risk to do it right the first time.&quot;<br /><br /><strong>Back at Chalmers</strong><br />Carl-Johan Seger is now recruited to Chalmers as Professor of Computer Science. Which means he is back at Chalmers where he started his studies in 1981, after nearly 34 years in Canada, the United States and Britain.<br />&quot;I don’t say I'm moving <em>back </em>to Sweden. I've been away for so long, so I say I'm moving to Sweden. It actually makes it a little easier for me.&quot;<br /><br />The first task at Chalmers is to build a verification system. Intel has proprietary ownership of the Forte system, so Carl-Johan Seger could not bring it to Chalmers for further research.<br />&quot;My wife usually says Forte is my fourth child, and maybe there is something to it. I have spent at least as many hours with Forte as with my three children.&quot;<br /><br />However, he has the old system to build on, the one he developed during his time as a researcher before leaving for Intel.<br />&quot;Now we are rebuilding, and this time, of course, it will go much faster because we already know the target.&quot;<br /><br /><br />Contact details: Carl-Johan Seger, <a href=""></a><br /><br /><em>Text: Malin Ulfvarson</em><br /><em>Photo: Anneli Andersson</em>Tue, 17 Oct 2017 09:00:00 +0200 cars can become more eco-friendly through life cycle assessment<p><b>​It is time to stop discussing whether electric cars are good or bad.
