And there’s more to come – the two centres will work even more closely in the future.</b></p><div>Centre Day featured a wealth of interesting speakers, who presented many examples of fruitful collaborations between the business community and Chalmers over the past decade. It was a day for celebrating the past and looking to the future, with many personal reflections on the benefits of collaboration.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330a.jpg" alt="" style="margin:5px" /> </div> <h5 class="chalmersElement-H5">A glimpse of history</h5> <div>Jan Grahn (above, to the left), professor of microwave technology at MC2 and head of the GigaHertz Centre, and Staffan Sjödin (above, to the right), head of Chase, summarised the histories of the two centres.</div> <div>“We’ve been fortunate enough to work in a variety of excellence centres in 20 years at Chalmers,” Grahn said. “This has truly been a joint venture, in which we’ve invested in and carried out research together. We’re grateful to Vinnova for making this all possible.”</div> <div>Grahn also commented on an editorial in Dagens Nyheter on 29 November about the Swedish government’s research proposal, which emphasises collaboration and utilisation. In the article, three researchers in business economics and sociology write that “collaboration is no guarantee for knowledge development or innovative ability.”</div> <div>“Today we’re going to see many examples to the contrary,” Grahn announced.</div> <div> </div> <h5 class="chalmersElement-H5">Praised Per-Simon Kildal</h5> <div>Staffan Sjödin summarised ten years with Chase, declaring that the excellence centre has generated 24 projects and preliminary studies, 693 conference papers, 280 journal articles and 22 doctoral theses so far.</div> <div>“Chase has had an intense impact on R&amp;D at companies,” Sjödin said.</div> <div>He also praised the late Chalmers professor Per-Simon Kildal, who was a key person at Chase. Kildal passed away unexpectedly last spring, and his name came up several times during the course of the day. It was clear how much he meant to the institution.</div> <div>Sjödin also wished the centre good luck with ChaseOn, the continuation of the Chase Centre for the next five years.</div> <div>“But it’s not too early to think about what will happen after 2021,” he said. “Hopefully we’ll be self-sufficient by then in one way or another.”</div> <div><div><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330c.jpg" alt="" style="margin:5px" /> </div> <h5 class="chalmersElement-H5">Eyes to the future </h5></div> <div>Next it was time for Erik Ström (above), professor of communications systems at the Department for Signals and Systems – S2 – to take the stage. He is the head of ChaseOn.</div> <div>“ChaseOn is the future and continuation of Chase. Both ChaseOn and the GigaHertz Centre applied for support from Vinnova. And both got it,” Ström announced, not without some pride.</div> <div>He and Grahn turned their eyes to the future, commenting that their two centres together collaborate with a total of 23 companies. Both the GigaHertz Centre and ChaseOn also work closely with the SP Technical Research Institute of Sweden (which will merge in 2017 with Swedish ICT and Innventia under the name RISE). ChaseOn is also partnered with the Royal Institute of Technology in Stockholm and the Västra Götaland region.</div> <div> </div> <h5 class="chalmersElement-H5">Establishing tighter bonds</h5> <div>The GigaHertz Centre and ChaseOn are now establishing even tighter bonds for the coming five-year period. They will remain separate centres, but will make up a consortium with a common steering committee and a joint international advisory council.</div> <div>“This creates many advantages in terms of technology and research,” Grahn says. “We have a golden opportunity here that will create endless possibilities for the future. It’s truly humbling to bring together such a vast array of skills.”</div> <div>Ström and Grahn saw many advantages to the centres working more closely together. The collective skills of the 23 partner companies create completely new opportunities for collaboration in new projects and teams. More results will become available to everyone, the strategic impact will be greater and the centres will become even more attractive to new partners. All this will enhance synergies within Chalmers in terms of coordination and outreach.</div> <div><div><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330d.jpg" alt="" style="margin:5px" /> </div> <h5 class="chalmersElement-H5">Personal and humorous </h5></div> <div>Rik Jos (above) from the company Ampleon was an adjunct professor of microelectronics at MC2 for 12 years, until 2016. He gave a personal, sometimes humorous story about his collaboration with the GigaHertz Centre and Chalmers over the past decade.</div> <div>“When I was asked to speak here today, I was struck by two things: 1. It was an honour to be asked. 2. Looking back, I realise that I’ve also aged!” he joked.</div> <div>Jos listed several good reasons why he chose to work with Chalmers in the framework of the GigaHertz Centre:</div> <div> </div> <div><ul><li>An enthusiastic and highly skilled team</li> <li>Complete coverage of the chain – from semiconductor processes to linearisation</li> <li>Project teams reach critical mass</li> <li>Research fields are jointly decided by all partners</li></ul></div> <div>He also had several recommendations for the future, and felt that the international advisors have an important role: </div> <div>“They provide calibration with centres in other countries and a connection that shows us what direction to grow in.”<br /><br /></div> <h5 class="chalmersElement-H5">Chase is a strength </h5> <div>Christian Fager, associate professor in the microwave electronics division at MC2, talked about his experimentation with the MOOC concept (online courses). He ended with the observation: </div> <div>“We’ve got very interesting times ahead.”</div> <div>Mats Andersson was the CEO of Bluetest in 2006–2011. Bluetest was founded by Per-Simon Kildal and currently employs 35 people.</div> <div>“Chase has been a strength for us,” he said, “and a key element of our ability to move from research into industry.”</div> <div><div><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330l.jpg" alt="" style="margin:5px" /> </div> <h5 class="chalmersElement-H5">Fruitful collaboration </h5></div> <div>Lars-Inge Sjökvist (above), CEO of Gapwaves, brought down the house when he announced that the company was listed on the Nasdaq exchange on 18 November.</div> <div>“We’ve had a fruitful collaboration with Chase over the years,” he commented.</div> <div>Gapwaves also demonstrated a gap antenna in the special exhibition of applications that MC2’s industrial relations coordinator Cristina Andersson set up for Centre Day.</div> <div><div><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330f.jpg" alt="" style="margin:5px" /> </div> <h5 class="chalmersElement-H5">International expertise </h5></div> <div>Each of the centres has had its own international advisory council. The plan was that each of those councils would have a representative on site, but due to an airline strike, the GigaHertz Centre’s expert, Fadhel Ghannouchi from the University of Calgary in Canada, couldn’t make it to Gothenburg. Christoph Mecklenbräuker from the University of Vienna in Austria had better luck and was able to provide us his thoughts on Chase.</div> <div>Erik Ström asked him to reply honestly to the question of whether he thought it was a good idea to establish closer bonds between the two centres. “Yes,” Mecklenbräuker said – after asking jokingly if he could phone a friend as in the popular television game show.</div> <div>But a key requirement for success, Mecklenbräuker pointed out, is that the researchers learn to speak and understand each other’s languages. </div> <div>“Chase had examples of extremely interdisciplinary projects that had a very slow learning curve,” he said by way of example. </div> <div>“We in the advisory council wondered if the situation would ever sort itself out – but in the end the projects were hugely successful. But you have to listen to each other; people think in different terms. The GigaHertz people will think in S-parameters, the ChaseOn people will think in bits per second. But your efforts will be rewarded!” </div> <div><div><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330m.jpg" alt="" style="margin:5px" /> </div> <h5 class="chalmersElement-H5">Chalmers an ideal environment </h5></div> <div>Paul Häyhänen, chairman of Chase, and Peter Olanders (above), chairman of the GigaHertz Centre, thanked the organising committee for a well-planned day.</div> <div>“Today we’ve seen a shining example of how this type of centre can contribute to the community,” Häyhänen said, “and also how we can create new start-ups and help big companies to grow even bigger. It’s been a fantastic day.”</div> <div>Olanders described Chalmers as an ideal environment for centres such as these, which is not least confirmed by the fact that Vinnova itself chose to place two of its excellence centres at the university. </div> <div>“Chalmers is definitely a dominant factor for success, but it’s also located in a region with exceptionally strong industry,” he said.</div> <div> </div> <h5 class="chalmersElement-H5">Industry gives extra shine</h5> <div>Vinnova was represented on site by its coordinators Jessica Svennebring and Tommy Schönberg.</div> <div>“My experience of the day is that both centres presented very interesting results from the past 10 years, and while that is certainly good, what gives it a bit of extra shine is the great interest on the part of industry to continue the collaboration,” Schönberg says. </div> <div>“This really confirms that this collaborative form is valuable to all involved parties: academia has the opportunity to publish excellent research results in relevant fields of the future, while industry gains key cutting-edge expertise in its technical field as well as a vital influx of skills in the form of knowledgeable future recruits.”</div> <div>ChaseOn and the GigaHertz Centre have now been granted SEK 70 million in funding from Vinnova for the 2017–2021 period.</div> <div> </div> <h5 class="chalmersElement-H5">Magnificent banquet</h5> <div>Centre Day ended with a magnificent banquet at Wijkanders Restaurang. The organising committee consisted of Cristina Andersson, Agneta Kinnander, Jeanette Träff, Erik Ström, Christian Fager, Jan Grahn and Staffan Sjödin.</div> <div>Chase and ChaseOn also took the opportunity to present a very elegant informational brochure entitled “Celebrating 10 years with Chase and the future with ChaseOn”.</div> <div> </div> <div>Text and photo: Michael Nystås</div> <div> </div> <h5 class="chalmersElement-H5">Read earlier news:</h5> <div><a href="/en/departments/mc2/news/Pages/Centre-Day-summarizes-ten-years-of-successful-research.aspx">Centre Day summarizes ten years of successful research</a></div> <div> </div> <div><a href="/en/areas-of-advance/ict/news/Pages/Strong-recognition-for-Chalmers-industry-collaboration-within-wireless.aspx">Strong recognition for Chalmers industry collaboration within wireless</a><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330b.jpg" alt="" style="margin:5px" /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330e.jpg" alt="" style="margin:5px" /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330g.jpg" alt="" style="margin:5px" /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330h.jpg" alt="" style="margin:5px" /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330i.jpg" alt="" style="margin:5px" /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330j.jpg" alt="" style="margin:5px" /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/centre_day_665x330k.jpg" alt="" style="margin:5px" /><br /></div>Mon, 16 Jan 2017 11:00:00 +0100http://www.chalmers.se/en/departments/ppd/news/Pages/dont-waste-the-trash.aspxhttp://www.chalmers.se/en/departments/ppd/news/Pages/dont-waste-the-trash.aspxDon&#39;t waste the trash<p><b>​Most people can agree that it would be more sustainable to reuse materials in the trash that we throw away to make new products. Even though, it’s not that much of the waste that is being used again. What is it that makes recovering resources from waste so difficult? In the doctoral thesis ”Designing out waste: exploring barriers for material recirculation” by Isabel Ordonez Pizarro we find out what some of the common problems are when it comes to recirculating materials in society and suggestions for how to overcome them.</b></p>​Since the topic is so broad, Isabel has done several studies where she has looked at three different stages that might be needed to recirculate materials in society, and the material flow between these. The stages are production, use of products and disposal of products.<br /><br />– By comparing the results found in all these studies together, we could see that there were six main problems common for all stages. For example lack of reliable information on secondary materials and unclear responsibilities. The results gave us a better understanding of the difficulties for material recirculation in society. To be able to work in waste management, production systems or sustainable consumption, you need to be aware that these are stages inside a larger recirculation system, and that all stages need to move towards the same goal of material recirculation, Isabel says.<br /><br />To be able to reach the goal of material recirculation, Isabel has four suggestions for policy instruments and argues that designers working in the waste management branch would facilitate collaboration with production and waste sorting for users.  <br /><br />Most of the research done in this field have been about how to change the production, for example with ”designing for recycling” or by implementing leasing systems in industry that allows producers to get their products back for remanufacturing and recycling. In Isabel’s research, she chose to see if it is possible to recirculate materials that are discarded today. Starting with waste management instead of production.<br /><br />– Resource recovery from waste has been covered by the waste management branch, but not specifically with the goal of making new products. So, to look at this problem with my professional perspective as an industrial designer is something different and my results are both expected and unexpected. For example, it was expected to see that designing with waste materials is difficult to do. With all the available sustainable design methods I expected more designers to actively include ”End-of-life” considerations when they do product development. I was also surprised to learn how much recyclable or bio-degradable material is being incinerated due to a lack of waste sorting, she says.<br /><br />– In general, I think that people who are interested in circular economy or material recirculation will find my work useful. But I still think that it’s much work left to do. I would like to establish material recirculation hubs in urban areas, where local producers, secondary material providers, waste managers and makers can meet and create new ways of collaborating to enable material recovery. I also find it interesting to develop more efficient, decentralized waste management solutions and I believe that it would help users to sort their waste better, Isabel says.<br /><br />Isabel will be presenting her doctoral thesis ”<a href="http://publications.lib.chalmers.se/publication/246393-designing-out-waste-exploring-barriers-for-material-recirculation">Designing out waste: exploring barriers for material recirculation</a>” on January 27 at 13.00 in Virtual Development Laboratory.<br /><br />After the defence, Isabel would like to apply for new project funding to continue doing research that may help material recirculation. She is also looking forward to finally get some time to do her own design again, with discarded material of course.<br /><br /><span><em>During her doctoral studies, Isabel have collaborated with other PhD students from Borås University, KTH and India.

The winners later on received their awards from the hand of Nobel laureate Sir James Fraser Stoddart.</b></p><div>​<img src="/SiteCollectionImages/Institutioner/MC2/News/agget_2016_665x330c.jpg" alt="" style="margin:5px" /><br />It was the 14th consecutive year for Chalmers popular technology competition for tricky fifth graders. During two days the entrance hall of the MC2 house murmured of happy children and their teachers. This year, 1 900 students from 50 schools with a total of 150 entries participiated.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/agget_2016_665x330d.jpg" alt="" style="margin:5px" /><br /><strong>Ingenious crafts</strong> </div> <div> </div> <div>The challenge is to design a solution that makes it possible to release a normal egg from 15 meters height without cracking. Prizes are awarded in three categories: The technically smartest solution, best-looking solution and best presentation.</div> <div> </div> <div>To meet the challenge you have to protect the egg as smart as possible. This year, the children had put their eggs into ingenious crafts, representing everything from Pokémon Figures to minions from the world of film.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/agget_2016_665x330e.jpg" alt="" style="margin:5px" /><br /><strong>Started in 2003</strong> </div> <div> </div> <div>Save the egg was started by the chalmerists Per-Anders Träff and Lars Ragnar Nerelius in 2003. They call themselves jokingly &quot;äggledare&quot; (oviduct) and &quot;äggstra project manager&quot;. The interest for the event has increased every year since its inception.</div> <div> </div> <div>&quot;There were so many notifications that we had to expand with an additional group of cempetitors. Also, the activities in the Concrete Hall is extended by a few hours&quot;, says Per-Anders Träff (picture below).</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/agget_2016_panne_665x330b.jpg" alt="" style="margin:5px" /><br /><strong>Third year at MC2</strong> </div> <div> </div> <div>For the third consecutive year the event took place in the entrance hall at the Department of Microtechnology and Nanoscience – MC2.</div> <div> </div> <div>&quot;It actually works better than in the Copper Bowl, where we were before. The fact that it was a climbing facility they had dampening mats on the floor, which we didn't were allowed to remove. The mats gave the crafts a more easy landing, and more eggs survived. Here the height is better and the environment is more challenging&quot;, says Per-Anders Träff.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/agget_2016_665x330i.jpg" alt="" style="margin:5px" /><br />The competition is organized by Chalmers University of Technology and Tekniska Samfundet, which manages the information and administration. At their side are around 50 students who act as functionaries. Per-Anders Träff also mentions Barbara Lindgren who has made invaluable contributions over many years. She belongs to the department Communications and Marketing at Chalmers. From Tekniska Samfundet Dorotea Blank is involved. </div> <div>In addition to the challenging competition part, it also contains an exciting experimental workshop, Experience Engineering, in which the kids see and test various technical smart devices at close range in a total of twelve stations. They also get the opportunity to do their own experiments. </div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/agget_2016_665x330g.jpg" alt="" style="margin:5px" /><br /><strong>Uncertain future</strong> </div> <div> </div> <div>But the future of the race is uncertain. Per-Anders Träff retires in February, and a decision on the continuation of Save the egg has not yet been taken.</div> <div> </div> <div>&quot;I can set up this more times if Chalmers wants me to. I think it is important that the competition is maintained in order to get interest in technology at this age. My motto is to arouse interest and also that children should know about Chalmers&quot;, he says.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/agget_2016_665x330l.jpg" alt="" style="margin:5px" /><br />On 14 December, it was time for the award ceremony in conjunction with the Chemistry Prize winner Sir James Fraser Stoddart's lecture at the Conference Centre Wallenberg.

The contribution has a consistent theme and a well-made construction in the shape of a blue figure with arms and legs. The egg was kept in a little holder on the front of the figure, which protected from hits caused of the fall. The construction fell down safely with its well-made parachute. The figure was colourful and the design was excellent, for that reason the team is awarded the aesthetic price. </div> <div> </div> <div> </div> <div> </div> <div><strong>Best presentation</strong></div> <strong> </strong><div><strong> </strong></div> <strong> </strong><div><strong>Silver Bird</strong></div> <strong> </strong><div><strong> </strong></div> <strong> </strong><div><strong>Karl Johansskolan, Gothenburg</strong></div> <div> </div> <div>The presentation of &quot;Silver Bird&quot; begins by explaining the underlying thoughts: &quot;Hypothesis&quot; and also &quot;Method,&quot; which are both described individually. Then the components are described clearly under the headline &quot;Material&quot;. The heading &quot;What happened&quot; describes the tests conducted in the class room. Everything is then presented on a large sheet where a nice-drawn picture of the craft is central. Also, there are additional pictures, blocks of text and clairfying arrows with text that explains it all.

This is something that Chalmers researcher Kristina Liljestrand wants to do something about. She is now giving companies in the food supply chain specific tools that can reduce both food waste and the environmental impact of food transport.</b></p><div>​It is hard to grasp the true scale of food waste in Sweden. Chalmers researcher Kristina Liljestrand uses an illustration of 23,000 trucks lined up in a row – filled with all the unnecessary food waste from producers, retailers and households each year. If you wanted to take a walk past all of the trucks, you would need a good pair of walking shoes because you would cover 430 kilometres.</div> <div> </div> <div>“The amount of food that is thrown away nowadays is incredible. Most food waste comes from consumers, but the amount lost in the logistics systems comes in a close second. By tweaking the logistics systems, we can ensure that the food maintains good quality and lasts as long as possible when it reaches the store,” she says </div> <h2 class="chalmersElement-H2">Unique research on food waste in the logistic systems</h2> <div>This is where Kristina Liljestrand's research comes into play. In recent years, she has figured out how companies in the food supply chain can work to reduce their environment impact in terms of both food waste and emissions from transports.</div> <div> </div> <div>Her work is unique in many ways since logistics improvement actions to combat the waste problem is a relatively unexplored area. There is no overview of ways that the companies in the supply chain can reduce waste – but this is something that Kristina delivers in her doctoral thesis.</div> <div> </div> <div><div>“The logistics systems are what bind everything together, from production of the food products to the products sitting on the store shelves.

Mallam states that contemporary naval architecture prioritizes a ship’s technical aspects, its construction costs and overall operational efficiency, while issues regarding the human element and detailed work environment design are often neglected. However, research reveals that inadequate design contributes to increased human error and accidents in maritime operations, thus revealing the importance of user-centred design and detailed work environment features.</span></div> <div><br /></div> <div>The main objective of Steven Mallam’s thesis is to better understand how ergonomic solutions can be effectively integrated into naval architecture and ship construction practices. Mallam argues that the design and layout of a ship's work environment influences how the onboard crew execute their work tasks, and ultimately needs to be addressed during conceptual design development.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SMT/Personporträtt%20intervjubilder/Steven%20Mallam.png" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" />Results from Mallam’s research have been used to develop new ergonomics integration methods and tools specifically tailored for naval architecture. This research has developed a visualization software program called E-SET (Ergonomic Ship Evaluation Tool). E-SET was developed to facilitate participatory practices in ship design and construction processes between multidisciplinary, geographically distributed stakeholders; and it particularly focuses on the increased inclusion and participation of crewmembers and ergonomists throughout ship development.</div> <div><br /></div> <div>Mallam’s thesis argues that improved design solutions can be achieved by better utilizing crew knowledge and experience in ship design and construction processes. However, the future success of ergonomics and user-centred design applications in new ship development requires a culture shift within the shipping industry itself and a champion within the industry to help promote and apply ergonomics across ship design and operations.</div> <div><br /></div> <div>For more information please refer to Steven Mallam’s published thesis<a href="http://publications.lib.chalmers.se/publication/244994"> “Distributed Participatory Design in Multidisciplinary Engineering Projects: Investigating a Sustainable Approach for Ship Design &amp; Construction”.​</a></div> <div> </div>Wed, 21 Dec 2016 09:00:00 +0100http://www.chalmers.se/en/news/Pages/Carbon-label-2016.aspxhttp://www.chalmers.se/en/news/Pages/Carbon-label-2016.aspxCarbon labelled lunches lowers emissions caused by Chalmers&#39; restaurants by 25 percent<p><b>​What’s for lunch – and why is your choice of food important? Through a unique collaboration a masters’ student, a group of scientists and the Student Union Restaurant have found a way to calculate a visualise food’s climate impact – and lower the greenhouse emissions caused by the lunch restaurant by 25 percent.</b></p><div>​The food we eat accounts for a fifth of the total amount of greenhouse gas emissions in Sweden, conversely the same amount as is caused by the transport sector. Meanwhile, it is difficult for consumers and kitchen staff to make informed choices with respect to climate impact every day while shopping for dinner, writing menus or ordering at restaurants. To make is easier to choose greener alternatives, a group of scientists, a master’s student and the Student Union Restaurant at Chalmers have worked together on an ambitious project that combines emission calculations, graphic design, psychology and cooking.</div> <div> </div> <div>The project was launched by Florentine Brunner’s Master’s thesis in Industrial Ecology at the department of Energy and Environment. Aided by her supervisor David Bryngelsson she investigated the level of emissions caused by the lunches served at the Student Union Restaurant – and designed a carbon label for the menu that illustrates the difference between lunch alternatives for the customers. In addition, she measured which courses the guests paying with their Student Union cards chose before compared to after the label was introduced.</div> <div>“I’m interested in consumer behaviour and was interested to see if a carbon label would impact the guest’s lunch choices,” says Florentine Brunner.</div> <h3 class="chalmersElement-H3">Certain popular options<img src="/SiteCollectionImages/20160701-20161231/Florentine%20Brunner%20i%20text.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /></h3> There is a plethora of factors that influence what we choose to eat: personal taste, old habits, allergies, health concerns, hunger, what we ate yesterday and so on. That being said, the statistics that Florentine Brunner analysed as part of her master’s thesis show that there are types of food that get more people to go for the greener alternatives. <div>“Overall, fast food-types of dishes are very popular – hamburgers, tacos and such – regardless of if they include meat, fish or are vegetarian. If you look only at the veggie alternatives, Asian dishes stand out as especially well liked: Thai food, noodle dishes of different varieties and Indian dishes are always a hit,” says Florentine Brunner.</div> <div> </div> <div>The carbon label for lunches had been received positively by guests of the restaurant and by the kitchen staff. The guests have become more prone to choose greener alternatives. As for the Student Union Restaurant, they have opted to continue using the carbon label and also taken the results of the calculations to heart, making the menus more environmentally friendly. They have, for example, stopped purchasing beef from parts of the world were emissions from the cattle industry are of particularly large scale.</div> <div>“The carbon label has inspired us to make certain changes in regard to purchasing ingredients. As of now, we are observing how our guests react to the label to get indications on how to plan our menus in the future. We hope to be able to present some statistics soon showing our guests how their choices have affected carbon emissions,” says Marcus Danielsson, assistant CEO of Chalmers Conference and Restaurant.</div> <h3 class="chalmersElement-H3">Emissions lowered by a fourth </h3> <div>How much of the impact that, in the end, can be attributed to the customers’ or the restaurant’s changed behaviour respectively is hard to break down, but the point still stands: the visualisation offered by the carbon label has made possible the gathered result of a 25 percent drop in emissions caused by the food served at the Student Union Restaurant.</div> <div> </div> <div>David Bryngelsson, post doc at the Department of Energy and Environment, is the one responsible for the research data at the core of the new carbon label. Together with a team of fellow researchers he has devised the program which calculates the amount of greenhouse gas emissions accumulated per lunch portion.</div> <div>“The label shows us qualities in the food that otherwise remain invisible to the lunch guests. Additionally, the climate impact of the food is highlighted – but not solely as something problematic. The guests can also see which alternatives are the least harmful to our climate. It’s easy to make a positive choice,” says David Bryngelsson.</div> <div> </div> <div>David Bryngelsson sees great potential in the emission calculation method and the carbon label outside of Chalmers as well. Together with colleagues he’s taking the concept further.</div> <div>“We’ve recently founded the company CarbonCloud to be able to target a wider range of parties within the restaurant sector by providing our program as a web based service. Several lunch restaurants on Chalmers’ two campuses have already signed up, and we’re bringing a group of new restaurants in Uppsala into the fold,” says David Bryngelsson.</div> <div> </div> <h3 class="chalmersElement-H3">Calculations based on peer reviewed data</h3> <div>The calculations of the amount of emissions caused per food portion are based on data provided in a paper published by earlier this year: <a href="http://www.sciencedirect.com/science/article/pii/S0306919216000129">How can the EU climate targets be met?

The simulations provide information about plasma turbulence and transport of plasmas that would be impossible or too expensive to study experimentally.</b></p>​The Plasma Physics and Fusion Energy group is involved in several international projects with the aim of realizing fusion as an energy source. The research is mainly done in collaboration with the Joint European Torus (JET), the largest fusion experiment currently in operation, and is focused on the preparation for the start of the experimental fusion reactor ITER that is being built in Cadarache, France. One of the current projects is focused on understanding how the hydrogen nuclei taking part in the fusion reaction can be replenished by injection of hydrogen pellets.<br /><br />JET is uniquely suitable for the study of ITER issues because of its size and since it shares many features of the ITER design such as a metallic (beryllium and tungsten) wall and tritium capability. The Chalmers research group uses data from JET experiments in order to run large scale computer simulations of the plasma turbulence and the associated transport of particles and energy.<br /><br />– These numerical experiments let us study the turbulence at a level of detail which is not possible in the actual experiment. We also look at the impact of changes in plasma parameters that would be impossible or too expensive to study experimentally. The tool we use for this is the GENE code, a so-called gyrokinetic code that evolves the particle distribution function in five space and velocity dimensions, explains Daniel Tegnered, PhD student in the Plasma Physics and Fusion Energy group.<br /><br />One of the crucial issues for ITER is how the plasma refuelling should be achieved. Particles of the plasma will unavoidably be lost, both to the wall, since the particle confinement will not be perfect, and also through the fusion reactions themselves which consume hydrogen nuclei. This makes continuous fuelling of the plasma a necessity. For ITER, so-called pellet fuelling is foreseen, whereby pellets containing appropriate hydrogen isotopes are injected at high speeds into the plasma. However, the pellets will not be able to reach the central part of the plasma with the highest densities and temperatures before being ablated. This will perturb the plasma’s temperature and density profiles, causing a “bump” in the plasma density as shown in the image. These particles must then be transported inwards by diffusion and convection caused by the turbulence.<br /><br />– Our simulations of pellet-fuelled JET discharges has shown that the turbulence under certain conditions can be stabilized in this region due to the “bump” in density and temperature says Daniel Tegnered.<br /><br />Further simulations of conditions more similar to ITER has also shown that a higher ratio of plasma pressure to magnetic pressure, a parameter important for the economic viability of future fusion reactors, also serves to stabilize the turbulence in this region. This in turn reduces the inward particle flux, potentially making pellet fuelling less efficient. Further analysis and simulations of ITER-like JET discharges will be crucial for the successful development of plasma scenarios for ITER.<br /><br /><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:8pt"><span style="font-family:calibri;font-size:14.66px;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;background-color:transparent"></span>The research was presented at <a href="https://kuleuvencongres.be/eps2016">the 43rd European Physical Society Conference on Plasma Physics</a> in Leuven, Belgium, 4 to 8 July 2016. </p> <p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:8pt">The paper by D.

Perhaps it was in the background when <a href="http://ait.gu.se/kontaktaoss/personal/bo_dahlbom">IT Professor Bo Dahlbom from the University of Gothenburg</a> took to the stage as the first speaker.</p> <p>Dahlbom said that in around 1900 Sweden was the poorest country in Europe, but just a few decades later it had become one of the richest countries in the world – thanks to the industrial revolution. Today we have leisure activities, major cities and transport options that were unimaginable just over 100 years ago.</p> <h3 class="chalmersElement-H3">Drones, chips and Siri in the digital revolution</h3> <p><img src="/SiteCollectionImages/Centrum/Wingquist%20VINN%20Excellence%20Center/Karusell%20WQL-dagen2016/Bo%20Dahlbom_WQL-dagen2016_340x340.png" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:250px;height:250px" /> Dahlbom believes that we are now in the digital revolution. Can we dream about the possibilities of the future now? Will they include autonomous cars that park themselves outside of town at night? Drones that fill the sky and take care of all transport runs? Chips implanted under the skin (like a form of digital tattoo) that update us on our health? Or that all your wishes can come true at the touch of a button – or via Siri? Dahlbom says that Swedish strategies for digitalisation are currently lagging behind and are based on the past rather than the future.</p> <p>Reindustrialisation of Sweden is not enough; instead we need to think in an entirely new way and Dahlbom highlights examples such as several companies with platforms where ownership of the product does not constitute the focal point – for instance, Apple, Uber and Airbnb. In Dahlbom’s opinion, in the same way that the major company Ford and the oil companies were the driving forces in the industrial revolution, today major companies such as Google, Amazon and Facebook are creating the global playing field. How do Swedish companies such as Atlas Copco, Sandviken and Volvo fit into that development? Dahlbom urged the companies to increase their visibility and urged everyone with children to buy this year’s Christmas present: a VR headset.

The team has developed the software, RD&amp;T, which can be used to perform statistical simulation of how much a product varies in shape and size, for example. The software can also show the degree of stability of a combination of several components and its sensitivity to variation. <a href="https://www.chalmers.se/en/staff/Pages/Soner-Camuz.aspx">Soner Camuz</a> demonstrated an example from industry partner Sandvik Coromant, which develops cutting tools.

In order to reduce fuel consumption, the aircraft needs to reduce its weight, which is why the ambition is to be able to weld components together to create a product that was previously cast in one piece. That entails a combination problem. In what sequence must you select parts to weld them together for the best result? Eleven parts produce more than three million different combinations. Forslund presented how he has succeeded in simulating the best sequence. <a href="https://www.chalmers.se/en/staff/Pages/julia-madrid.aspx">Julia Madrid</a> researches within the same area and presented a generic model for quality assurance of welded structures in an aircraft engine.

This team uses mathematical tools and algorithms to produce efficient and collision-free movements for operators and robots in manufacturing industries.<a href="http://www.fcc.chalmers.se/departments/geo/"> Jonas Kressin</a> gave a live demonstration during the seminar, in which the IPS software performed automatic, collision-free track planning for a welding station with four robots. <a href="http://www.fcc.chalmers.se/departments/geo/">Daniel Gleeson</a> then took over the demonstration and showed examples of how the robot movements can be optimised to save as much time as possible.

Surface treatment is the process in an automotive factory that uses the most energy, chemicals and water, while also producing the most waste. Previously the painting process itself was in focus, but Edelvik now demonstrated the virtual oven. Heat is used to dry the paint, but it also has a major impact on the size and shape of a product. It is therefore very important to be able to simulate what happens in the oven. “We have now addressed the painting and the oven. The next step is the ED coating process, and then we’ll take it step by step until we manage to simulate the entire factory,” said Edelvik.</p> <h3 class="chalmersElement-H3">Smart Assembly 4.0</h3> <p>The day concluded with <a href="https://www.chalmers.se/en/staff/Pages/rikard-soderberg.aspx">Professor Rikard Söderberg</a> Director of the centre, returning to the stage to talk about a prestigious project that the centre has been assigned responsibility for: <strong>Smart Assembly 4.0</strong>.

This fall, the Material &amp; Detail studio at Chalmers University of Technology is addressing the urgent need for sustainable compact housing for urban migrants with integrated storage. Through a partnership with the HSB Living Lab and the Smart Storage project, the studio has crafted future scenarios for domestic environments. The scenarios are rethinking the problem of storage which in some sense can be considered a luxury of the urban dweller and even more so in the future.</b></p>​<img src="/SiteCollectionImages/Institutioner/arch/nyheter/2016/framtidens_förvaring_3_340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />To design the storage units, the studio has chosen to work with two very different materials; sheets made of recycled PETG plastic and the vegetative part of a fungus; mycelium. The plastic sheets are formed using a robotic arm and a specific technique called Single Point Incremental sheet Forming (SPIF). To add rigidity to the structure, the plastic sheets are combined with mycelium which is a growing, organic material. Focus has been on how digital geometry undergoes a transition when applied to a material.<br /><br />The students have articulated their scenarios for the future through experimental furniture pieces that are now being built full-scale and will be installed in the HSB Living Lab at Chalmers campus Johanneberg. In an exhibition at the Living Lab the full-scale proposals will be displayed together with seven competing design entries and the experimental research the studio has done during the semester on both mycelium and robotic forming of plastic sheets.<br /><br /><strong><a href="/en/departments/arch/calendar/Pages/The-Future-of-Domestic-Storage.aspx">A warm welcome to the opening of the exhibition on Tuesday the 20th of December from 16.00 in the HSB Living Lab located at Chalmers University of Technology.</a> </strong>Presentation and various talks will take place at 17.00.

Not an entirely unusual sentence in the days of frequent Internet fraud, but this time it proved to be true. The mail came from Facebook, and the research project which they have taken an interest in aims to develop tools that will enable websites to detect whether visitors have browser extensions installed. <br /><br />“Browser extensions provide a powerful platform to enrich browsing experience. At the same time, they raise important security questions. From the point of view of a website, some browser extensions are invasive, removing intended features and adding unintended ones” says Andrei Sabelfeld. <br /><br />In some aspects the interests of the involved parties (users, website owners and providers of browser extensions) collide. The user installs extensions for their needs and wants, which may be the use of smileys, to block ads, keep track of passwords for different sites and services and so on. The provider of extensions may want to be able to assure the user that the extension works to, for example, block all ads. On the other hand, anyone with a website that provides a service may want to be able to control what happens in the visitor's browser. A bank or authority may not want an extension to handle their data, and Facebook, for example, may not want an extension to take control over which ads should be displayed. <br /><br />“We will develop the dual measures of making extension detection easier in the interest of websites and making extension finding more difficult in the interest of extensions” says Andrei Sabelfeld “and in the next step we will investigate a browser architecture that allows a user to take control in arbitrating the conflicting security goals.” <br /><br />This means that for example a bank may request to be very restrictive, and only allow certain extensions, denying all others. In that case, the browser will present the user with the option to run only the permitted extensions, and disable all others for that site. <br /><br /><strong>​<br />Contact</strong><br />Professor Andrei Sabelfeld, Software Technology division, Computer Science and Engineering.<br /><a href="mailto:andrei@chalmers.se">andrei@chalmers.se</a>​​​<div>Phone: +46 31 772 10 18</div> Sun, 11 Dec 2016 00:00:00 +0100http://www.chalmers.se/en/departments/mc2/news/Pages/New-method-leads-one-step-closer-to-quantum-computer.aspxhttp://www.chalmers.se/en/departments/mc2/news/Pages/New-method-leads-one-step-closer-to-quantum-computer.aspxNew method leads one step closer to quantum computer<p><b>​Researchers at MIT and Chalmers, with collaborators, have developed a new method to improve superconducting quantum electronic circuits, and thus get one step closer to the future quantum computers. The findings were published on 8 December in the renowned scientific journal Science, with Jonas Bylander, assistant professor at the Quantum Device Physics Laboratory at the Department of Microtechnology and Nanoscience – MC2 – at Chalmers as one of the co-authors.</b></p>In their work, the researchers at MIT (Massachusetts Institute of Technology) and Chalmers designed and applied a technique to pump unpaired electrons, called quasiparticles, away from an electronic device. The result is a three-fold improvement in performance and a substantial reduction of noise and time variations.<br />&quot;We can now pump away the electron charges, quasiparticles, which are loose and disturb our qubit. This makes the qubit very stable, so that it becomes easier to use in a quantum computer. We made the life of a quantum state three times longer by pumping away the quasiparticles&quot;, says Jonas Bylander (picture below).<br /><img src="/SiteCollectionImages/Institutioner/MC2/News/jbylander_665x330b.jpg" alt="" style="margin:5px" /><br />The idea of constructing a quantum computer – which can solve some complex computational problems that a conventional computer cannot – appeared in the early 1980s. A quantum computer uses quantum mechanical interference to perform computations. The basic unit of quantum computers is the quantum bit, or &quot;qubit,&quot; which can be both one and zero simultaneously, in a &quot;coherent superposition&quot;.<br /><br />So far, quantum computing has been realized only in systems with a small number of qubits, but over the last ten years there has been a steady increase in the size and complexity of these devices.<br /><br />Some of the most promising candidates for implementing a quantum computer involve superconducting circuits, which have now been made to serve 100,000 times better than when they were first invented. In a superconductor, cooled below its critical temperature, electrons pair up into so-called Cooper pairs allowing currents to flow without any resistance. This means that the circuits can be driven without any heat dissipation, which is crucial for maintaining quantum coherence.<br /><br />Up until now, however, the performance of qubits in superconducting circuits has been limited by residual, left-over unpaired electrons (quasiparticles) present in the devices. These non-superconducting electrons jump around, and their charge disrupts the functioning of the circuit. By instead pumping away these quasiparticles, the life of a quantum state can be extended.<br />&quot;We expect that these results will be important in the understanding of larger-scale superconducting circuits for quantum computing&quot;, says Jonas Bylander.<br /><br />With the project are also researchers from the Peter Grünberg Institute in Germany, the University of California, US, The Institute of Physical and Chemical Research (RIKEN), the Center for Emergent Matter Science (CEMS) and the University of Tokyo in Japan.<br /><br />Text and photo: Michael Nystås<br />Illustration: Philip Krantz, Krantz NanoArt<br /><br /><a href="http://science.sciencemag.org/content/early/2016/12/07/science.aah5844">Read the article &quot;Suppressing relaxation in superconducting qubits by quasiparticle pumping&quot; in Science</a> &gt;&gt;&gt;<br />Fri, 09 Dec 2016 06:00:00 +0100
