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 on Digitalised Electricity Networks<p><b>​A new cross-disciplinary research project targets the next generation technologies for electricity distribution.

The technology is now finding its way to the market through ZeroPoint Technologies AB,  a startup company founded by professor Per Stenström and his former PhD student Angelos Arelakis.</b></p><img src="/SiteCollectionImages/Institutioner/DoIT/News/Angelos.jpg" class="chalmersPosition-FloatRight" alt="Angelos Arelakis" style="margin:5px" />When Angelos Arelakis began his doctoral studies with Per Stenström at Chalmers in 2010, they sat down to discuss possible topics for the dissertation, and the potential of memory compression came up. Per Stenström suggested &quot;a simple experiment to get things on the road&quot;, and the results of those tests were far beyond all expectations. The research that has followed has now evolved into a promising business concept. <br /><br />Usually the subject of memory compression is about compressing data to be stored or transported without processing. In modern computers arithmetic operations are performed in the CPU, which means that data must be fetched from memory when calculations are to be made, traffic that costs both time and energy. The new technology developed at Chalmers handles active data, while it's being processed. <br /><br />&quot;The benefit of the technology is increased memory capacity, but also increased CPU and memory throughput, which basically will lead to improved performance without affecting the physical size of the memory, or the energy consumption,&quot; says Angelos Arelakis. <br /><br />He left Chalmers earlier this year to become chief system architect at ZeroPoint Technologies AB, the company he founded with Per Stenström in 2015, with the goal of commercializing the technology he developed as a PhD student. The company aims to release its first product on the market in 2017, and as the technology can be applied to all types of data, the potential customers are companies that deal with everything from smartphones to major computer centers. Already in the early research results, Per Stenström anticipated future commercial opportunities, and the first patent application was filed in 2012. Since then, six more applications have been submitted, and the first patent has been granted. <br /><br />Solutions that improve storage capacity through different compression systems and methods are already on the market, some are even fast enough to also provide improved memory capacity. What's unique with the technology from Zeropoint is the combination of speed, intelligent compression and generality. Because the compression algorithms are implemented in hardware logic rather than in the software, they become extremely fast, and the software developers can continue as usual without the need for any adjustments. The company has evaluated various applications in collaboration with several international IT companies. <br /><br />&quot;There is no golden business model, you need to do trial and error. We have taken different applications to some potential customers, and they need to verify that the technology works. If it doesn't make sense, it's not meaningful to proceed. The product we are closest to launching now is a licensed IP core,&quot; says Angelos Arelakis. <br /><br />ZeroPoint Technologies AB has received start-up contributions from, among others, Chalmers Ventures and Qamcom, to take the product to the market. Angelos Arelakis has also been awarded a scholarship from <em>King Carl XVI Gustaf's 50th birthday foundation for science, technology and the environment</em> to further develop his research. The company currently employs about 8 people, but recruits continuously for new positions. The research at Chalmers was conducted within the project Euroserver, in EU FP7. <h3 class="chalmersElement-H3">Contact </h3> <div>Angelos Arelakis, <a href=""></a> <br />Per Stenström, <a href="/en/departments/cse/calendar/Pages/"></a></div> <div><br /></div> <div><h3 class="chalmersElement-H3">Related links</h3></div> <div><a href="">ZeroPoint Technologies AB</a> <br /><a href="">The EU-project Euroserver</a> </div> Mon, 10 Jul 2017 00:00:00 +0200 second call for WASP PhD student positions is now open<p><b>​Wallenberg Autonomous Systems and Software Program (WASP) announces 22 new PhD student positions.

Even traditionally simple objects such as step counters, thermostats, and light bulbs begin to enjoy wireless communication. On the other hand, many applications are not simple, they are extremely mission and safety-critical. A wireless glucose sensor must quickly and reliably exchange information with, for example, an insulin pump to ensure a patient’s well-being, and two autonomous vehicles approaching an intersection must coordinate and decide within a split second which car shall cross first.<br /><br /><div><img src="/SiteCollectionImages/Institutioner/DoIT/News/olaf.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:160px;height:212px" />Olaf Landsiedel, associate professor in the Networks and Systems division at Computer Science and Engineering, was recently awarded the SSF grant “Framtidens forskningsledare” for the project “Ultra Low-Latency, Low-Power Wireless Mesh Networks”. Current approaches in wireless networking maintain routes in the network, and external factors such as interference and mobility affect these routes, and will force the network to constantly repair them. If a route cannot be repaired sufficiently fast, messages will be delayed, and potentially lost. </div> <div> </div> In the project, which is based on many years of research, Olaf Landsiedel and his colleagues will work on a novel approach, taking on the challenge of exploiting the physical phenomena of the capture effect (the fact that when two signals are present, one will with a higher probability catch the stronger of the two) to design a communication scheme that will ensure that if there is a route towards a destination, it will be found instantly, regardless of the external factors. <div> </div> <div>“With this approach, we want to take existing algorithms that work in, for example, the data center world, where they have significantly more compute power, bandwidth and energy, and redesign these algorithms so they can be employed in the much smaller sensor networks, and operate – on batteries – with very limited compute power and bandwidth” says Olaf Landsiedel. </div> <div> </div> <div> </div> <div> </div> <div><strong>Contact</strong></div> <div>Associate Professor Olaf Landsiedel, Networks and Systems division, Computer Science and Engineering.</div> <div><a href=""></a>​​​</div> <div>Phone: +46 31 772 10 96<br /><br /><a href="">Swedish Foundation for Strategic Research</a><br /><a href="">Press Release in Swedish &quot;Framtidens forskningsledare&quot;</a><br /><br /></div> <div> </div> Wed, 21 Dec 2016 00:00:00 +0100 awards Chalmers web security research<p><b>Facebook has acknowledged the work of Chalmers researcher Andrei Sabelfeld and his team, supporting research on improving the security of browser extensions.</b></p><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/DoIT/News/FacebookAndrei5.gif" alt="" style="margin:5px;width:400px;height:273px" />Chalmers researcher Andrei Sabelfeld received an e-mail reading &quot;We have decided to give you an unrestricted gift of <span></span><span style="display:inline-block"></span>$ 30,000&quot;. 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=""></a>​​​<div>Phone: +46 31 772 10 18</div> Sun, 11 Dec 2016 00:00:00 +0100 WASP Industrial PhD student positions<p><b>​WASP will open the second call for Industrial PhD student positions 24 January 2017.</b></p>​<strong>Timetable</strong><br />Opening date:  2017-01-24<br />Application due date:  2017-03-31<br />Date of decision:  2017-06-08<br />Earliest start:  2017-08-01<br />Preliminary 15-20 industrial PhD positions are foreseen for this call.<br />Details concerning the application process will be posted in connection with the opening of the call.<br /><br />Source: <a href=""></a><br />Chalmers contacts: David Sands &lt;<a href=""></a>&gt; and Christian Berger &lt;<a href=""></a>&gt;<br />Fri, 02 Dec 2016 08:00:00 +0100 approach to computing boosts energy efficiency<p><b>​A European research project led by Chalmers University of Technology has launched a set of tools that will make computer systems more energy efficient – a critical issue for modern computing. Using the framework of the project programmers has been able to provide large data streaming aggregations 54 times more energy efficient than with standard implementations.</b></p>Energy consumption is one of the key challenges of modern computing, whether for wireless embedded client devices or high performance computing centers. The ability to develop energy efficient software is crucial, as the use of data and data processing keeps increasing in all areas of society. The need for power efficient computing is not only due to the environmental impact. Rather, we need energy efficient computing in order to even deliver on the trends predicted. <br /><br />The EU funded Excess project, which finishes August 31, set out three years ago to take on what the researchers perceived as a lack of holistic, integrated approaches to cover all system layers from hardware to user level software, and the limitations this caused to the exploitation of the existing solutions and their energy efficiency. They initially analyzed where energy-performance is wasted, and based on that knowledge they have developed a framework that should allow for rapid development of energy efficient software production. <br /><br />“When we started this research program there was a clear lack of tools and mathematical models to help the software engineers to program in an energy efficient way, and also to reason abstractly about the power and energy behavior of her software” says Philippas Tsigas, professor in Computer Engineering at Chalmers University of Technology, and project leader of Excess. “The holistic approach of the project involves both hardware and software components together, enabling the programmer to make power-aware architectural decisions early. This allows for larger energy savings than previous approaches, where software power optimization was often applied as a secondary step, after the initial application was written.” <br /><br />The Excess project has taken major steps towards providing a set of tools and models to software developers and system designers to allow them to program in an energy efficient way. The tool box spans from fundamentally new energy-saving hardware components, such as the Movidius Myriad platform, to sophisticated efficient libraries and algorithms. <br /><br />Tests run on large data streaming aggregations, a common operation used in real-time data analytics, has shown impressive results. When using the Excess framework, the programmer can provide a 54 times more energy efficient solution compared to a standard implementation on a high-end PC processor. The holistic Excess approach first presents the hardware benefits, using an embedded processor, and then continues to show the best way to split the computations inside the processor, to even further enhance the performance. <br /><br />Movidius, a partner in the Excess project and developers of the ​<a href="">Myriad</a> platform of vision processors, has integrated both technology and methodology developed in the project into their standard development kit hardware and software offering. In the embedded processor business, there has been a gradual migration of HPC class features getting deployed on embedded platforms. The rapid development in autonomous vehicles such as cars and drones, driving assist systems, and also the general development of home assist robotics (e.g. vacuum cleaners and lawnmowers) has led to the porting of various computer vision algorithms to embedded platforms. Traditionally these algorithms were developed on high performance desktop computers and HPC systems, making them difficult to re-deploy to embedded systems. Another problem was that the algorithms were not developed with energy efficiency in mind. But the Excess project has enabled and directed the development of tools and software development methods to aid the porting of HPC applications to the embedded environment in an energy efficient way.<br /><br /> <h4 class="chalmersElement-H4">About EXCESS</h4> EXCESS consortium unites Europes leading experts in both HPC and embedded computing.

The project, Securing Practical Web Applications, will attempt to deal with two of the most common methods of attack on the web today.</b></p><p>OWASP (Open Web Application Security Project) is an open, global organization working for the security of software applications, with a focus on web applications. At the top of the organization's list of risks on the internet is code injection, where an attacker injects untrusted data as part of a command or query. The hostile data can then trick the service to execute commands, or provide access to the data without proper authentication. Another common method of attack is Cross Site Scripting (XSS), when the attacker sends text-based scripts that exploit the browser. Almost any source of data can be attacked, including internal sources such as data from a database.</p> <p><img src="/SiteCollectionImages/Institutioner/DoIT/Profile%20pictures/ST/Andrei-S-0216.png" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />&quot;A problem with today's web is that it is based on &quot;all or nothing&quot;. Code on a web page has the same rights regardless of where it comes from; from the web page itself, from a third party, such as advertising or statistics, or as the result of an attack&quot;, says Andrei Sabelfeld.</p> <p>In the project <strong>Securing Practical Web Applications</strong>, Andrei Sabelfeld and his research group will, among other things, work to enable web developers to restrict a site's access to external resources, through mechanisms that will define security policies to verify that the code comes from an approved source. The collaboration with Google also implies that there will be opportunities for experiments with security policies for Google's web services and products, as well as opportunities for support in web browsers for the developed security policies.</p> <p>In another part of the project, general techniques for modular and secure sandboxing of untrusted code will be designed. The scenario is that of untrusted code that needs to be loaded in the browser, and used for rendering the results of computation to the user while preventing network communication.</p> <p>&quot;There are many independently interesting applications scenarios for this type of sandboxing, such as loan or tax calculators, that need access to private financial information, which should not leave the browser. We will explore the limits of what can be achieved to isolate untrusted components of a web application&quot; says Andrei Sabelfeld.</p> <p>As an additional challenge, these security measures need to be adapted to be implemented with little to no impact on the systems performance noticeable to the user. </p> <strong>​<br />Contact</strong><br />Professor Andrei Sabelfeld, Software Technology division, Computer Science and Engineering.<br /><a href=""></a>​​​<div>Phone: +46 31 772 10 18</div> ​<br /><strong>About the grant</strong><br />Google received 950 applications in this year's call, and granted 151 of them.<br />The grant for &quot;Securing Practical Web Applications&quot; is 67,845.00 USD<br /><a href="">Information about Google Research Awards</a><br />Tue, 16 Feb 2016 00:00:00 +0100 award to Chalmers master thesis in space electronics<p><b>​Earlier this year, the master thesis project &quot;SEU Mitigation Techniques for Advance Reprogrammable FPGA in Space&quot; carried out by Fredrik Brosser and Emil Milh was awarded the 2014 scholarship from the Swedish Society of Aeronautics and Astronautics.

Since FPGAs are reconfigurable, the circuit implementation process is very flexible which is important from a cost perspective. However, since FPGAs are based on aggressively scaled fabrication process technologies, they are sensitive to the radiation that space electronics inevitably is exposed to. <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/DoIT/News/Lilla-Polhem-m-UB.gif" class="chalmersPosition-FloatRight" alt="Fredrik Brosser and Emil Milh with award presenter Ulf Bengtsson, chairman of the Swedish Association of Graduate Engineers. &lt;br /&gt;&lt;i&gt;Foto: Pernilla Pettersson&lt;/i&gt;" style="margin:5px" />&quot;This thesis project can pave the way for a new type of space electronics&quot;, the award committee noted. &quot;Brosser and Milh have shown how conventional FPGAs can replace the custom technology used today, which can lead to cost reductions as well as higher performance and extended lifetime of the systems.&quot; </div> <div><br /></div> <div>The thesis was carried out within the Embedded Electronic System Design master's program at the Department of Computer Science and Engineering and at RUAG Space i Gothenburg. <div><br /></div> <div>Fredrik Brosser and Emil Milh accepted the Lilla Polhemspriset award at the Polhem festivities in Stockholm November 17, when Sveriges Ingenjörer also conferred Polhemspriset 2015. </div> <div><p><br /></p> <p>The report is available for download here:<br /><a href=""></a><br /></p> <p>The work also provides the basis for an article that was presented at the &quot;2014 International Conference on Field-Programmable Technology (FPT)&quot;: <br /><a href=""></a> </p> <p><br /></p> <p><strong>Contact: </strong><br />Fredrik Brosser, +44 7477 28 5431, <a href="" rel="nofollow"></a><br />Emil Milh, +1 412 587 3140, <a href="" rel="nofollow"></a> <br />Per Larsson-Edefors, handledare och examinator, +46 31-772 17 00, <a href="" rel="nofollow"></a><br /></p> <p><br /></p> <p><br /></p></div></div> Tue, 08 Dec 2015 00:00:00 +0100 Report on Data Driven Innovation<p><b>The OECD report “Data Driven Innovation: Big Data for Growth and Well-Being” was recently released. Professor Devdatt Dubhashi from the Computer Science and Engineering department was an expert consultant during the preparation of the report.​</b></p>Professor Devdatt Dubhashi’s contribution especially involved the issue of education to support data driven innovation. One of the highlighted considerations in the report concerns the shortage of data specialist skills, and the need of education.<br /><br />The OECD report improves the evidence base on the role of Data Driven Innovation for promoting growth and well-being, and provide policy guidance on how to maximise the benefits of DDI and mitigate the associated economic and societal risks.<br /><br />Main policy considerations:<br />1. Recognise that infrastructure in the digital economy includes not only broadband networks, but also data<br />2. Encourage investments in data, data sharing and reuse, and reduce barriers to data flows that could disrupt Global Value Chains (GVCs)<br />3. Balance between the benefits of openness and legitimate concerns over privacy and intellectual property rights<br />4. Focus on SMEs which face severe barriers to the adoption of DDI-related technologies<br />5. Address shortages of data specialist skills, which point to missed opportunities for job creation<br />6. Anticipate and address the disruptive force of Data Driven Innovation (DDI) that could lead to a new digital data divide<br />7. Take a whole-of-government strategic approach that leverages data as the “new R&amp;D” in innovation systems <br /><br />Devdatt Dubhashi was also part of the panel &quot;Developing skills for Data Driven Innovation&quot; at the Global Forum on the Knowledge Economy 2014, arranged by OECD, and participated in a panel at the Science Technology and Society (STS) Forum 2014, a gathering of Nobel laureates, CEOs and scientists from all over the world.<br /><br /><br />The OECD report: <a href="" target="_blank">Data Driven Innovation: Big Data for Growth and Well-Being</a><br />Thu, 22 Oct 2015 15:00:00 +0200
