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.

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.

The latter is a necessity for these systems, as their inherently varying (and often big) volumes of data, generated to provide autonomous functionality, demand instantaneous, real-time processing, often as close to the sensing devices as possible. </p> <p><img src="/SiteCollectionImages/Institutioner/DoIT/News/DEBS.gif" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />In the paper, <strong>DEBS Grand Challenge: Deterministic Real-Time Analytics of Geospatial Data Streams through ScaleGate Objects</strong>, the team showed how its ScaleGate method, combined with their new algorithm for constant time-processing of the required functions can solve the challenge (more info here <a href=""></a>). </p> <p>&quot;With our methods it became possible to achieve impressive results, we were able to run the given queries and process one year of data, 173 million tuples, generated by 43,000 taxis at a rate of approximately 260,000 tuples/second. That is one year of data in approximately ten minutes&quot;, says Vincenzo Gulisano. </p> <p>The team expresses that they are happy to see that research and industry, with this award, is acknowledging the impact that of work in real-world, real-time analytics. Real-time analytics are accelerating transformation of business and society to smarter ones. The change is a dramatic one with changes also on the models that business and society has adopted so far. </p> <div><strong>The authours:</strong><br />Vincenzo Gulisano<br />Yiannis Nikolakopoulos<br />Ivan Walulya<br />Marina Papatriantafilou<br />Philippas Tsigas </div> <div><br /></div> <div><br /></div> <div><a href="">Link to the extended technical report &gt;&gt; </a></div> <div><br /></div> <div><a href="">Link to the poster presented at the conference &gt;&gt;</a></div>Tue, 07 Jul 2015 07:30:00 +0200 investment in autonomous systems and software development<p><b>​Chalmers is one of four Swedish universities in a comprehensive 10-year commitment to research in autonomous systems and software development – strategically important areas for Swedish industry, and part of a paradigm shift affecting our society as a whole.</b></p>​ <div>The Wallenberg Autonomous Systems Program, WASP, is funded with an enormous SEK 1.8 billion – a powerful investment in basic research, education, training and recruitment.</div> <div> </div> <div>The Wallenberg Foundation underlines that the investment will give Sweden an internationally leading position in the program's scientific fields and thus ultimately contribute to Sweden's competitiveness as a technological and industrial nation.</div> <div> </div> <div><img class="chalmersPosition-FloatRight" alt="Mats Viberg, First Vice President of Chalmers" src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/MatsViberg_170x220px.jpg" style="margin:5px" />Research within WASP will provide fundamental knowledge, and foster progress in a number of areas where vehicles, robots, and complex software-intensive systems with intelligence achieve autonomy in interaction with humans.</div> <div> </div> <div>“Chalmers is well equipped to handle this type of initiative, spanning several departments and research groups.

But they entered it from two different directions. Mr Brosser completed the computer technology programme and Mr Milh completed the electrical engineering programme.<br />“We didn’t meet until the end of the master’s programme and the time had come for a degree project,” Mr Milh says.<br /><br /><strong>Difficult choice for awards committee</strong><br />The SSAA scholarship goes to the best project of the year associated with aeronautics and astronautics. Patrik Dammert of the Saab Group and Torbjörn Hult of Ruag Space, both of whom are on the awards committee, conferred the award.<br />They had a difficult choice this year.<br />“All of the papers we received were top class,” Mr Dammert says. “Winnowing them down to the very best was no easy task.”<br />The committee bases its assessment of the projects on the criteria of industrial utility, academy quality and writing style.<br />“Mr Brosser and Mr Milh were high up on all three, but they faced stiff competition,” Mr Dammert says.<br /><br /><strong>Happy prizewinners</strong><br />We got together with the two prizewinners at Hotel Novotel adjacent to the Klippan Cultural Reservation.<br />“We’re thrilled,” Mr Milh says. “Receiving this kind of acknowledgement is a wonderful feeling. We had to pinch ourselves to realise that we had done such a good job even though we knew that we had tried our very best. The response has been excellent.” <br /><strong>What is your degree project all about?</strong><br />“We studied ways of using a static random-access memory (SRAM)-based Field Programmable Gate Array (FPGA) for space applications,” Mr Milh says. “The highly flexible platform is not ordinarily used for space applications due to its sensitivity to radiation environments. We examined whether FPGA technology can be used in space and, if so, what methods are available for neutralizing negative effects of radiation. It became evident that substantial benefits could be obtained. For example, the system’s logical function can be reprogrammed while it is running. Ruag was also interested in that.”<br /><br /><strong>May be used for precision landings on Mars</strong><br />Mr Hult believes that the degree project can lay the foundation for exciting new applications. <br />“Groundbreaking technology like this would be highly suitable for future Mars missions, an area that we have launched studies about,” he says. <br />“Right now we’re working on a vehicle that will roam the surface of the planet. All the programming is in ordinary software. As of 2024, we’re considering the possibility of testing more sophisticated approaches that will permit precision landing. A programmed image recognition algorithm may be desirable during the actual landing but unnecessary afterwards. At that point it might be more appropriate to collect and analyse scientific data or manipulate a robotic arm. The FPGA platform will enable that kind of functionality. It can be used as an image processor while landing and a robotic arm controller afterwards. That flexibility offers tremendous advantages. Instead of two separate computers, we will need only one.”<br /><br /><strong>Fast lane to the real world</strong><br />The prizewinning paper was finished in June 2014. Both Mr Brosser and Mr Milh dived headlong into their careers. Mr Milh is stationed abroad as a trainee at Bombardier Transportation. <br />“I’ll be there until March 2016,” he says. “I’m at a production site in Katowice, Poland for the moment but will soon be leaving for Pittsburgh, Pennsylvania to take a job as a project manager. It’s something like a three-stage rocket -Sweden to Poland to the United States.”<br />Mr Brosser is working at Arm in Cambridge, UK. The company designs low-energy processors for smartphones, tablets and other devices.<br />“I help customers develop their system-on-chip systems with Arm processors,” he says.<br /><strong>Last but not least—what will you be doing with the money?</strong><br />“It will certainly cover airline tickets from England and maybe a beer or two at the airport,” Mr Brosser smiles.<br />“Probably not to fly home,” Mr Milh says. “Perhaps a little adventure over the summer holidays.”<br /><br /><strong>Gothenburg’s unique position</strong><br />One of the most important purposes of the scholarship is to spur interest in the airline and space industry.<br />“We have had to put up with the traditional view that it is a boring sector,” Mr Hult says. “We need to attract bright young minds to study these fascinating questions. We contend with the lure of gaming development and other more trendy areas but we hope that the scholarship will help bring more awareness.”<br /><br />Mr Dammert is quick to mention Gothenburg’s unique position in the field.<br />“We have a microwave hub with Saab, which develops radar, and Ruag, which stands pretty much all alone in its area,” he says. “There are a number of incredibly exciting tasks and problems to tackle.”<br />“We collaborate very closely with Chalmers University of Technology,” Mr Hult says.<br /><br />Per Larsson-Edefors, a professor at the Department of Computer Science and Engineering at Chalmers and the examiner for the scholarship winners, attended the awards ceremony at Hotel Novotel in Gothenburg.<br /><br /><strong>Text and photo:</strong> Michael Nystås<br /><br /><strong>Caption:</strong> Scholarship recipients Fredrik Brosser and Emil Milh flanked by Per Larsson-Edefors (left) and Torbjörn Hult (right), Ruag Space, and, at the far right, Patrik Dammert, Saab Group<br /><br /><a href="">Read the prizewinning degree project of Mr Brosser and Mr Milh</a> &gt;&gt;&gt;<br /><br /><strong>Swedish Society of Aeronautics and Astronautics &gt;&gt;&gt;</strong><br />The Swedish Society of Aeronautics and Astronautics (SSAA) is a nationwide, nonprofit and nonpartisan organisation with approximately 2,000 members. Established in 1933, it promotes aeronautics and astronautics development in Sweden. Among the members are professionals in the airline and space industries, as well as those who have a general interest in the technologies.<br /><a href=""></a> <br /><br /><strong>Citation of the prize committee &gt;&gt;&gt;</strong><br />Fredrik Brosser and Emil Milh have completed a degree project entitled, ”SEU Mitigation Techniques for Advanced Reprogrammable FPGA in Space.”<br />The purpose of the project was to evaluate options for using commercial SRAM-based FPGAs in space applications and assess the methods that may be needed. <br /><br />The effort was both theoretical and practical. The project began with a very basic review of various techniques for handling faulty circuits, both those used in current industrial applications and those that have emerged from recent research. The report describes the theoretical background very well.<br /><br />The next step was to develop a general test connection to inject, detect and repair defects in physically programmed circuits. The connection was used to fully test the basic techniques that had been identified and to try out a series of variations. The results were analysed in terms of vital technical performance parameters, and performance was estimated for a typical space application.<br />The report is well-structured, easy to understand and academically superior. It can serve as guidance during the next stage, when SRAM-based FPGAs are first used by the space industry. Mr Brosser and Mr Milh carried out the project independently, demonstrating strong initiative, collaborative abilities and the determination to test new ideas, all of which combined to generate a highly laudable effort.Mon, 25 May 2015 07:00:00 +0200
