Yet they still do not truly understand what it is that they know.</b></p>​ <br />Some people are afraid that there will be a time when computers get so smart that they form liaisons and take over the world. Shalom Lappin, Professor of Computational Linguistics at the University of Gothenburg, is not one of them.<br /><br /><a href="https://clasp.gu.se/about/people/shalom-lappin" target="_blank"><img src="https://www.gu.se/digitalAssets/1551/1551090_1543951_shalomlappin.jpg" alt="Shalom Lappin, University of Gothenburg" class="chalmersPosition-FloatRight" style="margin:5px" /></a>“The revolution in artificial intelligence that has arrived with the deep learning technology is still in its infancy, and even though it’s developing fast, I don’t think the idea of malicious super-agents is a real prospect that we have to worry about in the near future.” <br /><br /><strong>Computers only have the ability to reason</strong> about the task for which they are trained. They can find patterns and associations in millions of data, thus become better than humans in playing chess, translating and writing texts and driving a car. But as soon as we leave a specific and defined area and jump to another they are lost.<br /><br />“My personal feeling is that we will never quite get to the point where machines have something that resembles general reasoning power. But I could well be wrong”, says Shalom Lappin.<br /><br /><strong>Computers’ weakness is that they don’t really understand anything</strong>, adds Richard Johansson, Associate Professor at the division of Data Science at Chalmers. But with the help of machine learning, they can be very good at recognizing informative patterns. Therefore, they are very good at understanding languages in both speech and writing.<br /><br /><a href="http://www.cse.chalmers.se/research/lab/people/richard-johansson/" target="_blank"><img src="http://www.cse.chalmers.se/research/lab/wp-content/uploads/2015/01/1593485_img_4469-e1477032356847-237x300.jpg" alt="Richard Johansson, Chalmers" class="chalmersPosition-FloatRight" style="margin:5px;width:220px;height:278px" /></a>“The development is gradual, sometimes in leaps. Google translate is much better now than ten years ago, and today it provides useful translations, but I hardly believe that professional translators use it to any large extent”, says Richard Johansson, and mentions a problem area for machine translation:<br /><br />“The word &quot;it&quot; is translated with &quot;den&quot; or &quot;det&quot; in Swedish, and sometimes you may need to go back a few sentences to understand what “it” refers to to be correct.<br /><br />The improvement of Google's machine translations in recent years is largely due to the switch from statistical translation to a deep learning model. This allows the system to understand the context and thus generate improved translations.<br /><br /><strong>How good can computers get at recognizing patterns and relations?</strong> The sky is the limit, says Shalom Lappin, and mentions the development of facial recognition as an example where the computer is already superior to humans.<br /><br />Translations are the flagship area of machine learning technology today, but how well do computers perform on language processing? Imagine, for example, reading a text to a computer and getting it processed and rewritten. Richard Johansson thinks it’s not impossible.<br /><br />“First, your speech signal will be converted into text, and that technology is relatively good already. Then the text will be rendered into a grammatically well-structured language. I think that is fully operational within a few years.”<br /><br /><strong>Is there a risk that the personal language will disappear?</strong><br />&quot;Yes, should people get lazy and formulate carelessly, the language can certainly get more generic and less personal. On the other hand, I think it will take a long time before computers can make major changes in texts, such as moving paragraphs or sentences to make them well-structured&quot;, says Richard Johansson.<br /><br /><br /><br /><ul><li><strong>Artificial intelligence</strong> refers to computers that imitate human cognitive functions such as learning and problem solving.</li> <li><strong>Machine learning</strong> is, simply put, algorithms that are trained to draw conclusions based on large amounts of data.</li> <li><strong>Deep learning</strong> is machine learning that uses so-called neural networks (see below) as a model for learning.</li> <li><strong>Artificial neural networks</strong> are self-learning algorithms that imitate the model of biological neural networks (such as the brain).

The aim is to increase the mobility between business and academia and thus enriching both environments.</b></p>​In total, 15 million SEK is distributed among 14 applicants. The Strategic Mobility contribution covers the costs corresponding to one year’s full-time work for a person who wishes to do research at a different workplace than his or her regular.<br /><br /><strong>Research on connectivity solutions for the internet-of-things</strong><br /><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/De%20tar%20chansen%20att%20gästforska%20inom%20industrin/Giuseppe_Durisi_200x245px.jpg" class="chalmersPosition-FloatRight" alt="Link to news article." style="margin:5px" />Information theory is the area of research in which Giuseppe Durisi, Professor at the department of Electrical Engineering, is active. It is a mathematical discipline that deals with optimal methods for representing, communicating, and storing digital information. His mobility grant project “Low-Latency Wireless Random Access for IoT connectivity” will be carried out at the company Qamcom in Gothenburg.<br />“One of the most critical research challenges in my field right now is how to provide secure, reliable, and low-latency wireless connectivity to a massive number of devices that want to exchange data”, says Giuseppe Durisi. “Such devices may be traffic and energy monitors, thermostats, smart watches, or other Internet of Things (IoT) sensors.”<br /><br />“I want to identify and test novel promising connectivity solutions”, Giuseppe Durisi continues. ”At Qamcom, we plan to identify the most relevant use-case scenarios together with selected Swedish municipalities. They are the natural stakeholders of my project, because municipalities may benefit significantly from the deployment of IoT solutions in terms of increased efficiency and cost reductions for the society.”<br /><br />Sweden has the ambition of becoming world-leading in using the opportunities brought by digitalisation. Exploiting IoT connectivity is one of the crucial first steps.<br />“Qamcom is a prominent player in the Swedish IoT landscape, and thus a natural partner to team up with, especially given their long history of successful collaboration with Chalmers. I appreciate their holistic system-level view, which complements my academic orientation”, he concludes.<br /><br />Giuseppe Durisi will be working part time for the project for 18 months, starting in June 2018.<br /><br /><strong>Radar systems at very high frequencies</strong><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/tbryllert_anna-lena_lundqvist_220x180.jpg" class="chalmersPosition-FloatRight" alt="Link to news article." style="margin:5px" />Tomas Bryllert is a researcher at the Terahertz and Millimetre Wave Laboratory at the Department of Microtechnology and Nanoscience – MC2. He works very broad with anything from device- and circuit technology all the way up to operating systems.<br />&quot;The last few years I have worked a lot with radar systems at very high frequencies (220 GHz, 340 GHz). These radar systems are then used to take high resolution 3D images and to do spectroscopy. We are interested in several applications of these radar systems – including process control in industrial reactors, security and atmospheric science,&quot; says Tomas Bryllert. <br /><br />He gets a one year’s full-time salary to be a guest researcher at the defence and security company Saab, and is looking forward to this opportunity: <br />&quot;I’m very glad and excited about taking on a new research area and a new workplace, at the same time I’m a bit worried about if I will have enough time for my commitments at Chalmers and for life outside of work.&quot;<br /><br /><strong>Combine Chalmers knowledge with Saab’s expertise in radars</strong><br />At Saab, Tomas Bryllert will investigate the possibilities with MIMO radar, that is, radar systems that consist of several transmit- and receive elements with individual control of each element. This is a continuation of the development of radars from systems based on mechanically scanned reflector antennas to electronically steered arrays. <br />&quot;There are many similarities with the next generation base stations for mobile networks that will also include electronically steered antennas. We hope to combine Chalmers knowledge in experimental radar systems and communications research with SAAB’s expertise in radars to demonstrate, and better understand MIMO radar,&quot; says Tomas Bryllert. <br /><br />Text: Yvonne Jonsson and Michael Nystås<br />Photo: Oscar Mattsson and Anna-Lena Lundqvist<br /><br /><a href="https://strategiska.se/en/receive-2017-strategic-mobility-contribution/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more about the Strategic Mobility contribution</a><br /><br /><a href="https://www.qamcom.se/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more about Qamcom</a><br /><br /><a href="http://saab.com/"><span></span></a><a href="https://www.qamcom.se/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /><span style="display:inline-block"></span></a><span>Read more about Saab</span><br /><br />Fri, 22 Dec 2017 11:00:00 +0100https://www.chalmers.se/en/departments/e2/news/Pages/Erik-Agrell-elected-Fellow-of-IEEE.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/Erik-Agrell-elected-Fellow-of-IEEE.aspxErik Agrell elected Fellow of IEEE<p><b>​From January 2018 Erik Agrell, Professor in Communication Systems at Chalmers, is elected IEEE Fellow for his contributions to coding and modulation in optical communications.</b></p>​IEEE Fellow is the highest grade of membership in the world’s largest technical professional organization, given to persons with an outstanding record of accomplishments in any of the IEEE fields of interest.<br /><br />“I regard this honour as a recognition of the truly interdisciplinary research we have been pursuing for many years”, says Erik Agrell. “When I started to work on fibre-optic communications in 2003, other researchers with my background, which is communication theory, were very much focused on wireless applications, at Chalmers as well as worldwide. Conversely, progress in optical communications relied largely on photonic hardware improvements. There was practically no interaction between communication theory and photonics.”<br /><br />Nowadays, this picture has changed completely. The internet and our whole information-dense society relies on a backbone network of optical fibres, supporting several terabits per second on a single fibre. <br /><br />“It is now widely recognized that the demands for ever-increasing data rates can only be met by including advanced digital communication techniques in the fibre networks. My team and our collaboration partners in the research centre FORCE were among the first to push this development, and we still have a leading role. We are bringing the worlds of photonics and digital communications closer together!” Erik Agrell concludes.<br /><br /><a href="/sv/personal/redigera/Sidor/erik-agrell.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about Erik Agrell and his research</a><br /><a href="/en/departments/e2/research/Communication-systems/Pages/Optical-communications.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Optical communications</a><br /><a href="/en/centres/force/Pages/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Fibre Optic Communications Research Centre, FORCE</a><br /><a href="https://www.ieee.org/membership_services/membership/fellows/index.html" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Information about the IEEE program</a><br />Tue, 05 Dec 2017 13:00:00 +0100https://www.chalmers.se/en/departments/mc2/news/Pages/New-report-highlights-the-first-decade-of-GigaHertz-Centre.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/New-report-highlights-the-first-decade-of-GigaHertz-Centre.aspxNew report highlights the first decade of GigaHertz Centre<p><b>​A fresh report highlights the first ten years of the GigaHertz Centre at Chalmers. &quot;During one decade, Chalmers has in GHz Centre collaborated with seventeen companies vastly differing in size, business and location,&quot; centre director Jan Grahn writes in his introduction.</b></p><img src="/SiteCollectionImages/Institutioner/MC2/News/ghz_centre_10%20yr-report_cvr_500px.jpg" class="chalmersPosition-FloatRight" width="251" height="355" alt="" style="margin:5px" />The GHz Centre report delivers a ten-year perspective of what research in microwave electronics between Chalmers and industry has resulted in. The impact is both educational, academic and industrial.<br />&quot;Using our partnership in GHz Centre, we have learned how to combine academic curiosity with the entrepreneurial mind-set in industry. As a result, we advance education, new knowledge and innovation in microwave technology for both university and multiple industries ranging from spin-off companies to large system houses&quot;, Jan Grahn writes.<br /><br />The GHz Centre is a centre hosted by MC2. Director Jan Grahn is a professor of microwave technology, at the Microwave Electronics Laboratory at MC2.<br /><br />The Vinnova funded centre is funded for another five-year term for the period 2017-2021.

The larger of these involves an investment into machine learning, deep learning and the next generation of AI. This has been termed “eXplainable AI” and involves asking the system how it reached a particular answer, whereby the system can justify its answers and use them in a general situation. The second pathway deals with increasing our understanding of the mathematical principles behind AI.<br /><br />Each of the two branches has resources to recruit 14 senior researchers and 40 research students, where the research students will become members of graduate schools and take specialist courses in relevant fields. The two new graduate schools will coordinate with the graduate school that has already been established within the framework of WASP, where just over 100 research students are currently studying. Both the senior researchers and the research students will be recruited at the universities that are participating in WASP, primarily Chalmers University of Technology, the Royal Institute of Technology, Linköping University and Lund University. Further Swedish universities, however, may also benefit from the research grant.<br /><br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/DavidSands_170x220px.jpg" class="chalmersPosition-FloatRight" alt="David Sands" style="margin:5px" />&quot;This expansion of WASP is a fantastic opportunity for Chalmers and Sweden to build on our existing strengths in AI, but also recruit and train the next generation of AI experts,&quot; says David Sands, Chalmers representative in the WASP Program Management Group.<br /><br /><br />The grant also provides SEK 70 million to reinforce computing infrastructure.<br /><br />“This is a unique investment, even in an international perspective. WASP will in this way obtain the resources needed to create the knowledge platform that Sweden requires if it is to continue to hold its position at the forefront of research and remain competitive,” says Mille Millnert, chair of the WASP board.<br /><br />With this extension, WASP will have a budget of SEK 3 billion between now and 2026. At least 250 research students will be educated, at least 75 of them being industry-based research students. This is a powerful investment with connections to many different parts within artificial intelligence, software development and principles of autonomy. The new grant will also enable the recruitment of 46 senior researchers, the construction of demonstrators (arenas in which the research and commercial worlds can meet in concrete projects), investment into computer infrastructure, guest researcher programmes, and international collaboration.<br /><br />For more information about WASP at Chalmers, contact:<br />David Sands, Professor of Information Security, <a href="mailto:dave@chalmers.se">dave@chalmers.se</a><br />Mats Viberg, First Vice President with responsibility for research, <a href="mailto:mats.viberg@chalmers.se">mats.viberg@chalmers.se<br /></a><br /><a href="https://liu.se/en/news-item/miljardsatsning-pa-svensk-ai-forskning">Read the full press release from Linköping University &gt;</a>Thu, 16 Nov 2017 11:00:00 +0100https://www.chalmers.se/en/news/Pages/Engineering-of-a-Swedish-quantum-computer-set-to-start.aspxhttps://www.chalmers.se/en/news/Pages/Engineering-of-a-Swedish-quantum-computer-set-to-start.aspxEngineering of a Swedish quantum computer set to start<p><b>​A SEK 1 billion research initiative is setting Sweden on course to a global top position in quantum technology.

The EU launches a ten-year venture of one billion euros in 2019. Even larger programmes exist in North America, Asia and Australia. IT companies like Google, IBM, Intel and Microsoft are also making significant investments. Safe and fast communication is a strong driving force for quantum technology.

We also present research at Chalmers that uses reinforcement learning.</b></p>​ <br />A grand challenge for artificial intelligence is to develop an algorithm that learns complex concepts from a blank slate and with superhuman proficiency. To beat world-champion human players at the classic strategy game Go, Google DeepMInd developed a program AlphaGo, trained through a combination of supervised learning based on millions of human expert moves and reinforcement learning from self-play. This program defeated Go champion Lee Sedol in a tournament in March 2016.<br /><br />A new version of the AlphaGo computer program, called AlphaGo Zero, was able to teach itself to rapidly master Go, starting from a blank slate and without human input, as reported in <a href="https://deepmind.com/blog/alphago-zero-learning-scratch/" target="_blank">a new paper published in Nature on 19 October</a>. It learns solely from the games that it plays against itself, starting from random moves, with only the board and pieces as inputs and without human data. And defeated its predecessor by 100 games to 0 after training for only 36 h.<br /><br />AlphaGo Zero uses a single neural network, which is trained to predict the program’s own move selection and the winner of its games, improving with each iteration of self-play. As the program trained, it independently discovered some of the same game principles that took humans thousands of years to conceptualize and also developed novel strategies that provide new insights into this ancient game.The new program uses a single machine and 4 TPUs while the previous version of AlphaGo was trained over several months and required multiple machines and 48 TPUs (specialized chips for neural network training).<br /><br />We will discuss the main principles and new extensions of reinforcement used in this work and at the end we will  briefly discuss research at Chalmers that uses reinforcement learning in autonomous driving and natural language technology research. <br /><br /><br /><strong>The seminar was held on 10 November 2017</strong><br /><span>Speakers: Devdatt Dubhashi, Mikael Kågebäck and others, Department of Computer Science and Engineering, Chalmers<span style="display:inline-block"></span></span><br />Location: RunAn, Chalmers Student Union Building, Chalmersplatsen 1, Johanneberg<br /><br /><br /><strong>Media coverage:</strong><br />The research paper from DeepMind caused a lot of media attention, also in Swedish media. <br />Chalmers machine learning experts have commented in Swedish media (in Swedish).<br /><ul><li><a href="https://svenska.yle.fi/artikel/2017/10/18/googles-ai-program-larde-sig-sjalv-att-spela-det-svara-bradspelet-go-finlandskt" target="_blank">Devdatt Dubhashi in Yle.</a></li> <li><a href="http://sverigesradio.se/sida/artikel.aspx?programid=406&amp;artikel=6801347" target="_blank">Mikael Kågebäck in Vetenskapsradion i P1</a>, and in <a href="http://sverigesradio.se/sida/artikel.aspx?programid=104&amp;artikel=6801896" target="_blank">P4 Göteborg</a>, also partly available <a href="https://www.facebook.com/P4SRGoteborg/videos/10155704848598529/" target="_blank">on Facebook</a>.  </li> <li><a href="https://www.svt.se/nyheter/vetenskap/artificiell-intelligens-tar-ett-stort-kliv-framat" target="_blank">Mikael Kågebäck in SVT vetenskap.</a>  </li></ul>Mon, 23 Oct 2017 17:00:00 +0200https://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/New-research-opportunities-as-ElectriCity-grows.aspxhttps://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/New-research-opportunities-as-ElectriCity-grows.aspxNew research opportunities for Chalmers researchers as ElectriCity grows<p><b>​ElectriCity, best known for the electric bus 55 in Gothenburg, is much more than just the bus.

This means exciting opportunities for several research areas, Per Lövsund explains. Self-driving vehicles, safety, community planning, noise, thermal optimization, control algorithms, vehicle dynamics, development and recycling of batteries and fuel cells, and charging station requirements are some examples of questions from different research fields, all of which can be studied within the framework of ElectriCity.<br /></p> <p><br /></p> <p>Researchers involved in ElectriCity have access to research platforms such as buses and other vehicles. The project’s demo arena also includes the new urban area Frihamnen and the development of south Chalmers Johanneberg Campus, with a stop for the ElectriCity bus. Here, safety aspects and new innovative solutions at the stop and interactions between vehicles and unprotected road users can be studied.<br /></p> <p><br /></p> <p>The fact that ElectriCity enters a new phase has already generated new research at Chalmers.<br /></p> <p><br /></p> <p>“One project about bus trains and one about autonomous docking at bus stops are just about to take off”, says Per Lövsund. “Another project investigates how bus drivers experience the effects of the Volvo Dynamic Steering system.”<br /></p> <p><br /></p> <p>A workshop is planned to be held at Chalmers to formulate projects on low-frequency noise in urban environment, modeling of noise impact and safety issues regarding quiet buses at bus stops.<br /></p> <p><br /></p> <p>“In the long run, perhaps other sectors could be included as well.

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="mailto:secarl@chalmers.se">secarl@chalmers.se</a><br /><br /><em>Text: Malin Ulfvarson</em><br /><em>Photo: Anneli Andersson</em>Tue, 17 Oct 2017 09:00:00 +0200https://www.chalmers.se/en/departments/mc2/news/Pages/Packed-Centre-Day-for-ChaseOn-and-GigaHertz-Centre.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/Packed-Centre-Day-for-ChaseOn-and-GigaHertz-Centre.aspxPacked Centre Day for ChaseOn and GigaHertz Centre<p><b>​On 14 November, Chalmers excellence centres ChaseOn and GigaHertz Centre will arrange their joint day in Palmstedtsalen.

For example, forecasts for energy use will be included, as well as any restrictions affecting the transmission possibilities.</div> <div> </div> <div>“Our project partner Akademiska Hus is already working actively to reduce energy consumption in the premises. Therefore, it will be an additional challenge for us to reach the goal of reducing energy imports by as much as 30 percent,&quot; says David.</div> <div> </div> <div>This autumn, construction work will start on campus and in December 2017, the first version of the energy marketplace will be launched. From autumn 2018, everything is planned to be fully operational and after one year of operation, conclusions will be drawn, useful for EU cities wanting to implement the system on a larger scale.</div> <div> </div> <div><strong>Continued research on the future energy system</strong></div> <div>“It's really an exciting project to work in”, says David. “We all contribute with different competences in the cooperation. In addition, it gives us the opportunity to continue our research about local energy systems and to further develop the models we have created. Small local energy systems will be increasingly important for fossil-free and renewable energy supply in the future. There is an increasing interest in this, which benefits the society and also means a profitable development for different types of property owners.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Chalmers%20blir%20unik%20handelsplats%20för%20energi/FED-forskare-DSC_6669_340px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /><em>Small local energy systems will be increasingly important for fossil-free and renewable energy supply in the future, according to </em><span><em> Kalid Yunus<span style="display:inline-block">,  </span></em></span><em>Anh Tuan Le, Zack Norwood and David Steen, Chalmers</em><span>'<span style="display:inline-block"></span></span><em> researchers in the FED-project.<br /></em></div> <div><br /><em></em></div> <div><strong>Text and photo:</strong> Yvonne Jonsson<br /> </div> <div><br /></div> <div><br /></div> <div><strong>Some objectives for the project</strong></div> <ul><li>Reduce the import of energy to the campus area by 30 percent</li> <li>Cut the energy peaks, when fossil energy is used, by 80 percent</li> <li>10 000 transactions on the local energy market</li></ul> <div> </div> <div> </div> <div><strong>About the project</strong></div> <div>The Fossil-free Energy Districts project, FED, is an innovative effort by the City of Gothenburg, Sweden, to decrease the use of energy and the dependence on fossil fuel in a built environment. A unique local market for electricity, district heating and cooling is being developed together with eight strong partners. Johanneberg Science Park, Göteborg Energi, Business Region Göteborg, Ericsson, RISE Research Institutes of Sweden, Akademiska Hus, Chalmersfastigheter and Chalmers University of Technology are all contributing with their expertise and knowledge to make FED attractive for other European cities as well. During 2017−2019 the FED testbed will be situated on Campus Johanneberg. FED is co-financed by the European Regional and Development Fund through the Urban Innovative Actions Initiative, an initiative of the European Commission for cities to test new solutions for urban challenges.</div> <div><br /></div> <a href="http://www.uia-initiative.eu/en/uia-cities/gothenburg" target="_blank"><div>Read more about FED at the homepage for UIA</div></a><div><br /></div>Wed, 27 Sep 2017 09:00:00 +0200https://www.chalmers.se/en/departments/e2/news/Pages/The-project-that-sets-the-standard-for-5G-in-vehicles.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/The-project-that-sets-the-standard-for-5G-in-vehicles.aspxThe project that sets the standard for 5G in vehicles<p><b>​The development of 5th generation mobile broadband systems, 5G to replace today&#39;s 4G, is in full swing. Chalmers is part of a two-year project that brings together industry and academia to develop a common global standard for future vehicle communication.</b></p>​“It's about using telecommunications to increase traffic safety and transport efficiency through connected and collaborative systems”, says Professor Erik Ström, Head of Communication and Antenna Systems at the Department of Electrical Engineering. “Today's wireless mobile system is not powerful enough to be used for vehicle communication, where safety always must be put first.”<br /><br />For traffic safety applications, very high demands are imposed on the reliability of the data being transmitted. In some cases, more than 99.999 percent of the transmitted information must also be delivered to the recipient.<br /><br />“In addition to the demands of high reliability, it is also crucial that data communication is fast and not delayed”, he continues. “In order to be traffic-safe, transmission times have to be as short as 5 milliseconds in certain use cases. This is very challenging.”<img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Projektet%20som%20sätter%20standarden%20för%205G%20i%20fordon/Erik_Strom_200x280px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><strong>Creates consensus among competitors</strong><br />In the project, competitors like Ericsson, Nokia and Huawei side by side, along with vehicle manufacturers like Volvo Cars and PSA, work out the common prerequisites for the 5G system and a global standard for vehicle communication.<br /><br />The work is about creating consensus and to agree on matters that need to be standardized. The telecom industry requires a common system platform to start from, when the manufacturers in the next step separately develop their products for the market.<br /><br />&quot;I am very pleased that we at Chalmers are taking part in setting the standard”, says Erik Ström. “It is an important and highly sought-after network to participate in, including both industry and other universities. We contribute, among other things, with knowledge from our fundamental research on positioning and wireless systems. In total, we expect the project to involve 46 month´s work for our researchers.”<br /><br />A part of the project is about vulnerable road users, such as pedestrians and cyclists. When the 5G technology is available in each person's mobile phone, data collection for example about position, direction and speed could be used to further enhance traffic safety in different situations.<br /><br />The project started in June 2017, and Chalmers made the first part-delivery in early September. By mid-2019, selected technology components will be demonstrated and project results incorporated into the 5G standard. The overall goal of 5GCAR is that vehicles connected with 5G technology will be out on the roads from 2020.<br /><br /><strong>Renewed confidence</strong><br />&quot;We are very pleased to, once more, been given the confidence to use our research in the development of technology that enables 5G in vehicles&quot;, says Erik Ström. “For us, this is the second project within 5GPPP. We have long and fruitful partnerships in the past with Ericsson and Volvo Cars and other 5GCAR partners.”<br /><br /><br /><strong>Facts about 5GCAR</strong><br /><ul><li>5GCAR stands for &quot;Fifth Generation Communication Automotive Research and Innovation&quot;.</li> <li>The project is funded by the EU and has a budget of EUR 8 million.
