The evaluation showed that the participants were satisfied or very satisfied and they particularly emphasized the wide range of prominent speakers who gave different perspectives on the current theme – opportunities and challenges of digitalisation.<br /><br />Our participants also represented a wide range. About 30 percent came from industry or private sector, slightly less than ten percent from the public sector and half of the participants were from Universities or research institutes. The remaining ten percent were students from Chalmers and University of Gothenburg.<br /><br />Chalmers DigiLab, a workshop for school children, which was arranged parallel to the seminar at Chalmers conference center, received 120 children over the two days. Twelve Chalmers students tutored the children under project management from Steve Cook, Norconsult.<br /><br /><strong>What do we take with us from our two days?</strong> A common message from the presentations was that the digitalisation process is here in its full speed. Many technologies exist today and many new are appearing, many of them developed at Chalmers. The question is how to apply and combine these technologies to obtain the best results?  The consequences of digitalisation will be enormous. The society has to deal with it.<br /><br />The seminar was a starting activity of a new initiative Digitalisation@Chalmers. The Area of Advance ICT has initiated an analysis on concrete digitalisation activities, and needs from industry and public sector, mapping them to Chalmers activities in research. The analysis will show the potential for Chalmers advances in the digitalisation process, for the future research, and research education. This will lead to new activities supported by ICT: preparation for new interdisciplinary projects and involvement in new national and international activities.<br /><br /><img src="/en/areas-of-advance/ict/events/digitalisation/PublishingImages/IvicaCrnkovic_250px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><br /><br />Ivica Crnkovic<br />Director of Chalmers Area of Advance Information and Communication Technology<br /><br /><br /><a href="http://www.plmportal.org/en/news-detail/the-interplay-between-digitalization-and-society.html" target="_blank">Read the summary from one of our prominent speakers, Ulrich Sendler &gt;&gt;</a><br /><br /><br />Links:<br /><a href="https://www.youtube.com/playlist?list=PLHXgzqnOl9moeyotLnX6iTj4-DiH3KaGH">All the presentations were filmed and are available here &gt;&gt;</a><br /><span><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/for-schools.aspx"><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/education/chalmers_digilab_200px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></a><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/for-schools.aspx"></a></span><br /><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/programme.aspx">The presentation slides &gt;&gt;</a><br /><br /><a href="https://www.flickr.com/gp/148750671%40N04/9e05ua">Photos from the days &gt;&gt;</a><br /><br /><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/for-schools.aspx"><br />Video from Chalmers DigiLab &gt;&gt;</a><br /><br /><a href="https://flic.kr/s/aHskWoZmhV">Photos from Chalmers DigiLab &gt;&gt;</a><br /><br /><br />Fri, 07 Apr 2017 08:00:00 +0200http://www.chalmers.se/en/departments/s2/news/Pages/Hearing-and-touch-mediate-sensations-via-osseointegrated-prostheses.aspxhttp://www.chalmers.se/en/departments/s2/news/Pages/Hearing-and-touch-mediate-sensations-via-osseointegrated-prostheses.aspxHearing and touch mediate sensations via osseointegrated prostheses<p><b>​ A new study has found that people with a prosthesis attached directly to their skeleton can hear by means of vibrations in their implant. This sound transmission through bones is an important part of osseoperception – sensory awareness of the patient’s surroundings provided by their prosthesis. This discovery sheds new light on the tactile and auditory perception of humans and can be used to develop improved prostheses.</b></p>​How can we help amputees regain tactile sensations and other natural feelings while grasping an object or walking on uneven ground?<br /><br />An international group of researchers in Sweden and Italy offers a new answer. They have demonstrated for the first time that patients with implanted osseointegrated prostheses (ones attached directly to the skeleton) are able to perceive external stimuli better by hearing through their limb implants.<br /><br />The investigation was conducted jointly in Sweden by Chalmers University of Technology, Sahlgrenska University Hospital, and the University of Gothenburg; all collaborating closely with Scuola Superiore Sant’Anna in Italy.<br /><br />In a recent paper in <em>Nature Scientific Reports,</em> the researchers presented a discovery that opens up new scenarios for developing novel artificial limbs. Even though the transmission of sound through skull bones is a well-known phenomenon, widely studied by Professor Bo Håkansson at Chalmers who was a participant in this study, it was not clear whether this also occurs through bones in the arms and legs and thus contribute to osseoperception – “feeling” arising from the mechanical stimulation of an osseointegrated prosthesis.<br /><br /><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Hearing%20and%20touch%20mediate%20sensations%20via%20osseointegrated%20prostheses/Max-Ortiz-Catalan_S8A7544-1_180px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br />“Until now, the consensus was that the sense of touch played the primary role in osseoperception for patients with artificial limbs fixated into their skeletons”, says Max Ortiz Catalan, head of the Biomechatronics and Neurorehabilitation Laboratory (BNL) at Chalmers and supervisor of the research.<br /><br /><br /><br />Francesco Clemente, who conducted the experiments as a visiting PhD student at BNL from the Biorobotics Institute of Scuola Superiore Sant’Anna, comments:<br /><br />“Using four different psychophysical tests, we have demonstrated that even subtle sensory stimuli can travel through the body and be perceived as sound. This hearing increases the individual’s sensory awareness, even in patients with osseointegrated implants in their legs.”<br /><br />These results show that osseointegration, which allows for stable mechanical attachment of robotic prostheses directly to the skeleton through a titanium implant, improves patients’ functionality, comfort, and ability to perceive the world around them.<br /><br />The researchers tested twelve patients with various degrees of amputation, both upper and lower limb amputees. All tests indicated that patients could perceive mechanical vibrations applied to their titanium implants, through hearing as well as touch. In particular, and synchronously with the vibrations in their arms or legs, patients reported audible sound. During the experiments, the researchers found that subjects with osseointegrated prostheses could perceive very small stimuli and react more quickly to them due to additional perception by hearing.<br /><br />“In practice, the stimuli received by the patients are perceived more strongly and carry more information because they are composed of two modalities; touch and hearing,” says Max Ortiz Catalan. “This is an important step forward in understanding the osseoperception phenomenon and, more generally, the tactile and auditory perception of humans. This discovery may offer a new starting point for implementing novel prostheses that provide enriched sensory feedback to the user.”<br /><br />Read the article in <span><em>Nature Scientific Reports:<br /><span style="display:inline-block"></span></em></span><span></span><a href="http://www.nature.com/articles/srep45363" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Touch and Hearing Mediate Osseoperception</a><br /><br /><strong>For more information, please contact:</strong><br />Max Ortiz Catalan, Department of Signals and Systems, Chalmers University of Technology, Sweden.<br />Tel: +46 70 846 10 65, <a href="mailto:%20maxo@chalmers.se">maxo@chalmers.se</a><br /><br /><strong>Facts about the research</strong><br />The investigation was conducted jointly in Sweden by the Signals and Systems Department at Chalmers University of Technology, the Centre for Advanced Reconstruction of Extremities at Sahlgrenska University Hospital, and the Institute of Neuroscience and Physiology at the University of Gothenburg; all collaborating closely with the Biorobotics Institute of Scuola Superiore Sant’Anna in Italy.<br /><br />Read more about the Biomechatronics and Neurorehabilitation Laboratory (BNL) at Chalmers:<br /><a href="http://www.bnl.chalmers.se/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />BNL website</a><br /><a href="https://www.facebook.com/ChalmersBNL/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Chalmers BNL on Facebook</a><br /><br />Thu, 06 Apr 2017 07:00:00 +0200http://www.chalmers.se/en/areas-of-advance/buildingfutures/news/Pages/SmartCities.aspxhttp://www.chalmers.se/en/areas-of-advance/buildingfutures/news/Pages/SmartCities.aspxJoint Area of Advance Workshop on Smart Cities initiated by Building Futures<p><b>​On March 8th 2017 AoA directors and profile leads from Building Futures, Energy, Transport and ICT came together to discuss the concept &quot;Smart City&quot; and identify challenges which can be tackled by joint research initiatives at Chalmers.</b></p>​Smart City has been one of the buzzwords that gained a lot of attention in recent years, yet there is little consensus about what a Smart City actually is or should be. The Area of Advance (AoA) Building Futures began a mapping process in November 2016 to gather information about the concept and systematically map related research activities at Chalmers. On March 8th 2017 AoA directors and profile leads from Building Futures, Energy, Transport and ICT came together to discuss the concept and identify challenges which can be tackled by joint research initiatives at Chalmers.<br /><br />Today, over 50 % of the world’s population live in cities, a proportion that the United Nations (U.N.) expects to increase to 66 % in 2050. The main question here is how functionality and resilience in growing cities can be assured? To many the answer seems to be “by making them smarter”. But how exactly do we make it happen? What technologies are needed and which city dimensions are affected? And finally, how can Chalmers’ Areas of Advance contribute to addressing this important challenge? <br /><br />The purpose of the mapping process initiated by Building Futures in November was to find answers to the above questions and to identify a structured way to utilize the concept of Smart Cities at Chalmers. AoA Building Futures director Henriette Söderberg explains that “often researchers are not aware of the fact that their projects directly contribute to the wide domain of Smart Cities. Our goal is to make the Smart City debate tangible for our researchers.”<br /><br />After laying the groundwork through literature review, several interviews with stakeholders from research, industry and the public sector were conducted. With respect to the <a href="/en/areas-of-advance/Pages/default.aspx">challenge-driven character of the Areas of Advance</a> 144 different Smart City challenges in 9 dimensions were collected and visualized on a large map. <br /><br />The Smart City challenge map was the point of departure for the AoAs workshop held on the 8th of March 2017. As a result of the workshop, five possible fields of action for the Areas of Advance were identified:<br /><br /><ul><li>Cyber security</li> <li>Circular economy</li> <li>Multimodal transport</li> <li>Virtual cities</li> <li>New urban planning</li></ul> <br />In the weeks to come, further strategic discussions within the Areas of Advance will take place and concrete next steps on how to anchor the Smart City topic at Chalmers will be taken. <br /><br /><img src="/en/areas-of-advance/buildingfutures/news/Documents/Workshop%208%20mars%202.jpg" alt="Workshop 8 mars 2.jpg" style="margin:5px" /><br /><br /><br />Fri, 31 Mar 2017 17:00:00 +0200http://www.chalmers.se/en/areas-of-advance/ict/news/Pages/Launching-GHzCentre-ChaseOn-joint-consortium.aspxhttp://www.chalmers.se/en/areas-of-advance/ict/news/Pages/Launching-GHzCentre-ChaseOn-joint-consortium.aspxSweden&#39;s largest research effort in microwave and antenna technology<p><b>​Two Vinnova competence centres, ChaseOn and GigaHertz Centre, now launch a joint consortium for research in microwave and antenna technology.

It leads to a transformation of virtually all elements of our life – the way of working, the way of living, the way we communicate, build knowledge, do business. Digitalisation affects our healthcare, welfare, democracy, environment. <br /><br />It can be compared with the greatest changes in the history of civilisation, such as the invention of writing. The new opportunities are extensive and not yet imaginable – digitised artefacts and their management enable radically new business opportunities, optimisation of production and resource usage, automated transport with autonomous vehicles, living in smart cities, efficient and reliable services of public sector, etc. <br /><br />At the same time, digitalisation brings many new challenges. A sustainable digitalisation requires capable handling of issues relating to privacy, security, democracy, as well as issues related to the transition that takes place when jobs disappear due to automation in production and services.<br /><br />To meet the challenges and create a sustainable future requires new knowledge and close collaboration between the various actors in the society. Our initiative seminar Digitalisation – opportunities and challenges, brings together experts from research, industry and the public sector to discuss the digitalisation progress and its potential consequences. <br /><br />Prominent researchers, experts and managers from industry and society will present and discuss perspectives on digitalisation, future, threats and promises for the society of today and tomorrow. A broad audience from academia, industry, the public sector, and general public are invited to the seminar.<br /><br />The two-day seminar will be organised in four broad themes offering new perspectives on digitalisation: Digital sustainability – how can we make our new digital world sustainable? Connected world – what are the abilities to connect and integrate artefacts, processes, technologies, and people? Data-driven innovation – how omnipresent information and knowledge can be enabled and optimally used? Automated society – how new intelligent systems can provide better services, without jeopardising important values like freedom and human relations?<br /><br />Digitalisation is here, but what about the future? We must also care for the future. To show this, our initiative seminar will additionally offer activities for school children.<br /><br />The initiative seminar is organised by Chalmers Area of Advance Information and Communication Technology, supported by Chalmers University of Technology and University of Gothenburg.<br /><br />We hope you will enjoy these two fantastic days, listen to our experts, and participate in the discussions.<br /><br /><img src="/en/areas-of-advance/ict/events/digitalisation/PublishingImages/IvicaCrnkovic_250px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br />Welcome!<br /><br />Ivica Crnkovic<br />Director of Chalmers Area of Advance Information and Communication Technology<br /><br />Go to event webpage:<br /><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/default.aspx">Chalmers Initiative Seminar: Digitalisation - opportunities and challenges, 15-16 March 2017</a><br /><br /><br />Thu, 09 Mar 2017 11:00:00 +0100http://www.chalmers.se/en/departments/s2/news/Pages/Microwave-helmet-yields-fast-and-safe-evaluation-of-head-injuries.aspxhttp://www.chalmers.se/en/departments/s2/news/Pages/Microwave-helmet-yields-fast-and-safe-evaluation-of-head-injuries.aspxMicrowave helmet yields fast and safe evaluation of head injuries<p><b>​Results from a clinical study demonstrates that microwave measurements can be used for a rapid detection of intracranial bleeding in traumatic brain injuries. A recently published scientific paper shows that health care professionals get vital information and can quickly decide on appropriate treatment if patients are examined using a microwave helmet.</b></p>​The study demonstrates a new health care application for microwave measurements. Previously, microwave measurements have been used to distinguish stroke caused by bleeding in the brain from stroke caused by cloth.<br /><br />The new study shows that the technology also applies to patients affected by traumatic brain injury, which is the most common cause of death and disability among young people. This type of injuries are often caused by traffic accidents, assaults or falls. An estimated 10 million people are affected annually by traumatic brain injuries.<br /><br />The study compared 20 patients hospitalized for surgery of chronic subdural hematoma – a serious form of intracranial bleeding – with 20 healthy volunteers. The patients were examined with microwave measurements which were compared to traditional CT scans. The results show that microwave measurements have great potential to detect intracranial bleeding in this group of patients.<br /><br />“The result is very promising even though the study is small and only focused on one type of head injury. The microwave helmet could improve the medical assessment of traumatic head injuries even before the patient arrives at the hospital”, says Johan Ljungqvist specialist in neurosurgery at the Sahlgrenska University Hospital. “The result indicates that the microwave measurements can be useful in ambulances and in other care settings.”<br /><span><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Strokefinder/MikaelPersson_200px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></span><br />Further studies of acute head injury patients are ongoing and planned in Sweden and abroad.<br /><br />“Microwave technology has the potential to revolutionize medical diagnostics by enabling faster, more flexible and more cost-effective care”, says Mikael Persson, professor of biomedical engineering at Chalmers University of Technology. “In many parts of the world microwave measurements systems can become a complement to CT scans and other imaging systems, which are often missing or have long waiting lists.”<br /><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Strokefinder/Mikael_Elam_200px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br />“It is challenging to develop a new clinical methodology, from early tests to a device for clinical use in a hyperacute clinical environment where routine care of patients cannot be delayed.

Similar to other industries, our welfare sector benefit from new technologies and innovation, which radically can improve healthcare, education and create more sustainable societies. <br /><br />But innovative solutions are sometimes difficult to scale for the welfare sector, due to incentive structures set by how the welfare state is organized, and the rapid development is a challenge to several of the structures currently in place. <br /><br />I will talk about how digitalization can create opportunities for the welfare state, and what challenges we see. Are there any key solutions to assure a benign development of innovation for all, in a society aiming for equal access? I will highlight examples I believe are important lessons to build upon for digital democracies with a focus on welfare for all.”<br /><br />Darja Isaksson is a member of the Swedish Government Innovation Council, where she focuses on matters related to how to use digitalisation for increased sustainability. She’s founded three successful agencies and has been rewarded Sweden’s most influential opinion maker for her efforts to increase awareness of the opportunities and challenges to society through digitalisation.<br /><br /><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/register.aspx">Register here for the seminar &gt;&gt;</a>Thu, 23 Feb 2017 11:00:00 +0100http://www.chalmers.se/en/centres/chaseon/news/Pages/Two-centres-together-meet-the-entire-need.aspxhttp://www.chalmers.se/en/centres/chaseon/news/Pages/Two-centres-together-meet-the-entire-need.aspxTwo centres together meet the entire need<p><b>​Today’s wireless communications systems have practically reached their maximum capacity. The next step, towards a terabit level, requires new technology. At Chalmers, a unique Massive MIMO testing environment is being built, a project in which Ericsson are pleased to be involved.</b></p>​In simple terms, future wireless communication requires two improvements: higher frequency spectrum and new antenna systems. Chalmers has the skills to achieve both – organised through two research centres, Chase and GigaHertz Centre, both funded by Vinnova. Through collaboration in the project MATE, they are jointly developing a test bed for Massive MIMO antenna technology.<br /><br />Björn Johannisson, research manager at Ericsson, is impressed with how the project has succeeded.<br />“It’s not always easy to create collaborative projects of this kind. The researchers need to get along, the partners have to find mutual interests, and the practical parts needs to be addressed. I’m impressed with how it has succeeded, and we see a great value in our collaboration with Chalmers,” he says.<br /><br /><img src="/en/centres/chaseon/PublishingImages/News/BjornJohannisson-quote_350px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />MIMO, or “multiple input-multiple output”, is a technology that improves transfer capacity by adding a large number of antennas in both transmitters and receivers, making it possible to transmit multiple data streams simultaneously. Future systems may involve hundreds, or even thousands, of antennas.<br />“It means that you transmit several streams of information that mix in the air and must then be separated at the receiving end. We are currently developing technology to handle this effectively, but in the MATE project we also want to enable higher frequencies, which adds to our challenge. This requires collaboration because the signal processing must be adapted to the properties of the hardware.”<br /><br />Chalmers and MATE are at the forefront of the research, Johannisson claims.<br />“There are a number of test beds developed at companies, but this is one of the first being created for high frequencies in an academic environment. Which is important to us since the academic research is more transparent, and we want the technology to become globally acknowledged.”<br /><br />To Ericsson, the technology is interesting for the next generation of mobile systems, 5G. Massive MIMO will, however, have a significantly wider area of use than simply mobile phones – everything from connected cars and production environments in factories to small gadgets with communication features. Within the MATE project, a rough draft of how it will work has been drawn up, but many issues remain to be resolved regarding the precise design of the technology.<br /><br />“The test bed that is soon completed will be an important platform for further work. When Chase continues in ChaseOn, we will collect measurement data in order to test algorithms and to provide insights into how high-performance antenna systems can be designed,” concludes Johannisson.<br /><br />Text: Lars Nicklason<br />Photo: Henrik Sandsjö<br /><br /><br /><img src="/en/centres/chaseon/PublishingImages/News/MATE_350px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:150px;height:225px" /><br /><br />More about the MATE project:<br /><a href="/en/projects/Pages/Massive-MIMO-test-bed.aspx">Massive MIMO test bed, project start</a><br /><a href="/en/areas-of-advance/ict/news/Pages/test-bed-for-multi-antenna-systems.aspx">Short interview with Thomas Eriksson at the start of the MATE project</a> (Feb 2015)<br /><br />Fri, 10 Feb 2017 09:00:00 +0100http://www.chalmers.se/en/areas-of-advance/ict/news/Pages/CatherineMulligan.aspxhttp://www.chalmers.se/en/areas-of-advance/ict/news/Pages/CatherineMulligan.aspxBlockchain – Trust for the 21st Century?<p><b>​A big challenge of today is to develop reliable technology that can bring trust to our increasingly digital society.

At the same time, corporations and cities are struggling to manage large data sets and to find appropriate ways to ensure appropriate and reliable decision-making using them in an increasingly digital world,” says Catherine Mulligan. <br /><br />“At the core of these issues is the notion of trust – how do we engender new models of trust in a digital world? Digital disruption therefore creates both great opportunity for society – but also increases the demands we must make on ourselves to assess when and how we should apply digital solutions.” <br /><br />A relatively new technology – Blockchain – has emerged as a potential answer to these questions and offers the opportunity to redefine how our governments, economy and society work through redefining the role of trust in these institutions. <br /><br />“Indeed, many claim that Blockchain will remove the need for intermediaries such as central banks, land registries and insurance agencies altogether and place trust back into the hands of individuals. A radically new world is promised – one that dismantles the established economic system that has been around since the industrial revolution and replaces it with a world where individuals can flourish and work together on an ad-hoc basis redefining how companies are owned and operate, how security solutions are built and maintained in democracies and how digital networks themselves are designed and delivered.<br /><br />Can Blockchain rise to these challenges or are we investing too much faith in a relatively new technology?  In her talk Catherine Mulligan will investigate these issues from a variety of perspectives building on over 30 proofs of concept delivered by Imperial College London’s Blockchain research team.<br /><br />Dr Catherine Mulligan is a Research Fellow in Innovation and Entrepreneurship with a joint appointment to the Department of Computing where she is Co-Director of the <a href="http://www.imperial.ac.uk/cryptocurrency" target="_blank">Imperial College Centre for Cryptocurrency Research and Engineering</a>.  <br /><br /><br /><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/default.aspx">Read more about our initiative seminar, and register today!</a>Thu, 02 Feb 2017 16:00:00 +0100http://www.chalmers.se/en/departments/tme/news/Pages/Maria-massaro-researches-radio-spectrum-regulation.aspxhttp://www.chalmers.se/en/departments/tme/news/Pages/Maria-massaro-researches-radio-spectrum-regulation.aspxWho is in charge of the radio waves in Europe?<p><b>​Mobile internet has become the backbone of our society, yet the regulatory framework of the radio spectrum has remained quite unexamined. Chalmers PhD student Maria Massaro has taken an international approach to the question, and shows how the EU exerts its influence on radio spectrum regulation at all levels – nationally, regionally and internationally.</b></p><div>​She chose her research area because it was unknown for her, and has spent the past years focusing on the policy and regulatory aspects of radio spectrum. Now Maria Massaro, PhD student at Chalmers Department of Technology Management and Economics, Division of Science, Technology and Society, has published her Licentiate Thesis: <em>Radio Spectrum Regulation in the European Union - A three-level context.</em></div> <div> </div> <h5 class="chalmersElement-H5">You examine the role the EU plays in radio spectrum regulation at international, regional and national level. Why is this so interesting - and important to shed light on?</h5> <div> </div> <div>&quot;When I heard about this area for the first time I could not really capture the importance of this “radio spectrum” for mobile operators, and why it was regulated. Therefore, I decided to dig deeper into the topic on radio spectrum regulation during my PhD&quot;.</div> <div> </div> <div>&quot;Mobile internet has become the backbone of our society. If radio spectrum was not regulated, it would not be possible to use mobile internet. The importance of regulating the radio spectrum has been increasingly acknowledged, in conjunction with the widespread use of mobile internet devices such as smartphones and tablets, but also machine-to-machine communications - The Internet of Things&quot;.</div> <div> </div> <h5 class="chalmersElement-H5">Is there a lack of knowledge in this area today?</h5> <div> </div> <div>&quot;Technical issues of radio spectrum use have constantly been addressed by engineering researchers, but the regulatory framework for radio spectrum has remained mostly unobserved. Only recently, radio spectrum regulation has revealed its potential as an interesting and challenging research area. In particular, the widespread use of mobile data has uncovered the need to revise existing regulation. It is common knowledge that mobile internet has become an essential component of our lives. Well, mobile internet is one among several public and commercial services reliant upon radio spectrum. In this context, the novelty of my research work stands on focusing on regulatory issues of radio spectrum - which have passed unnoticed so far - in a unique institutional setting, that of the European Union&quot;.</div> <div> </div> <h5 class="chalmersElement-H5">How would you describe your main conclusions? </h5> <div> </div> <div>&quot;Radio spectrum is considered a national resource, and national authorities define the rules for the use of the radio spectrum in their national territories. Nevertheless, when it comes to EU member states, the responsibility of regulating the radio spectrum is, to some extent, shared between national and EU authorities. My licentiate thesis illustrates the role the EU plays in radio spectrum regulation, looking at international, regional and national rules. It shows how the EU does exert its influence on radio spectrum regulation at all levels, although regulating the radio spectrum is a national responsibility&quot;.</div> <div> </div> <h5 class="chalmersElement-H5">What do you hope your research will lead to? </h5> <div> </div> <div>&quot;Firstly, I hope my research work will encourage more systematic research on radio spectrum regulation, in particular with respect to the potential positive or negative consequences of allocating responsibilities between national and EU authorities. Secondly, I hope that policy makers and regulators will recognize the crucial contribution that research can have for designing successful regulatory interventions&quot;.</div> <div> </div> <h5 class="chalmersElement-H5">How do you want to proceed with your research?</h5> <div> </div> <div>&quot;My plan for the next phase is to examine into more depth the distribution of responsibilities between national and EU authorities. A fundamental EU public policy priority is to create the so-called EU single market, which would require to transfer more power to EU authorities. Pursuing such policy objective requires to overcome the opposition of EU member states, which tend to safeguard their national prerogatives in many policy areas. My aim is to understand more about this power game in radio spectrum regulation and assess potential benefits and drawbacks of centralising or decentralizing responsibilities between EU and national authorities&quot;.<br /><br /><strong>Text: Ulrika Ernström</strong></div> <div><div> </div> <h4 class="chalmersElement-H4"><span>FACTS, RESEARCH AND MORE INFORMATION</span></h4> <div><span><span><div>More about <a href="/en/Staff/Pages/maria-massaro.aspx">Maria Massaro</a></div></span></span></div> <div><span><span>Read Marias </span></span><span>Licentiate Thesis: <a href="http://publications.lib.chalmers.se/publication/247685-radio-spectrum-regulation-in-the-european-union-a-three-level-context">Radio Spectrum Regulation in the European Union - A three-level context.</a></span></div> <div><span><span></span></span> </div></div> <strong> </strong><div><strong>ABOUT THE RADIO SPECTRUM:</strong></div> <div>The <a href="https://en.wikipedia.org/wiki/Radio_spectrum">radio spectrum</a> is a range of electromagnetic frequencies, also called radio waves, widely used in modern technology - particularly for mobile telecommunications.

This will mainly be ensured by the antennas of tomorrow.</b></p>​ <br />If you are at home watching a film and the TV picture suddenly freezes, it’s probably not a disaster. But in the future, if you are driving towards a junction, in which a cloud-based automated driving application optimally guides you and other vehicles through the junction at full speed – well, in that situation communication must always work,” says Mikael Nilsson at Volvo Cars.<br /><br />Of course, it will be a while before this becomes a reality, but other new communication applications are already being developed that demand a very high level of reliability.<br /><br />Volvo’s Road Friction Information is one example. The idea is that cars ahead share information about road conditions to nearby vehicles through the cloud, for example about icy or slippery conditions, which is intended to make the surrounding cars to take precautions in time. In such circumstances, a stable link can mean the difference between life and death. The same applies to E-call, the service for automatic electronic emergency calls from cars to emergency call centres that will become standard in all new cars in Europe by 2018.<br /><br /><img class="chalmersPosition-FloatRight" src="/en/centres/chaseon/PublishingImages/News/ChaseOn-Volvo-citat2_270px.jpg" alt="" style="margin:5px" />What happens if a car flips over and the antenna on the roof breaks?<br />“Within Chase we have examined various concepts for how to best position antennas on cars,” says Nilsson.<br /><br />The aim has also been to develop the antennas of tomorrow.<br />“You can build better receivers, switch to better cables between the antenna and the receiver, but that is much more expensive than building better antennas. They will be the most crucial element that affects the performance of the communications system.”<br /><br />Within ChaseOn, Volvo aims at developing an antenna concept that supports new 5G technology. It requires higher frequencies, which in turn demands more of the antenna’s performance and position.<br /><br />“We also plan to develop antennas that are compatible with cars made of materials such as carbon fibre and plastic, which lack a ground plane.”<br /><br />For Volvo Cars, the Chase collaboration has also had what Mikael Nilsson describes as “softer values”.<br />“It is important for us to be part of research hubs, to be visible in these contexts, for instance at conferences around the world at which Chalmers’ researchers participate. It gives us a good reputation and spark enquiries about new projects and collaborations. This exchange between Volvo and universities is perhaps the most important of all.”<br /><br /><img src="/en/centres/chaseon/PublishingImages/News/Chaseon-Volvo-MikaelNilsson_750px.jpg" alt="" style="margin:5px" /><br /><em>Mikael Nilsson, Technical Expert Wireless Communication at Volvo Cars</em><br /><br /><br />Text: Lars Nicklason<br />Photo: Henrik Sandsjö<br /><br /><br /><img class="chalmersPosition-FloatRight" src="/en/centres/chaseon/PublishingImages/ChaseOn_Logo_220x120px.jpg" alt="" style="margin:5px" /><strong>Antenna systems research centre ChaseOn</strong><br />ChaseOn is a continuation of the very successful Chase centre.

That is one of many questions researchers want to have answers to when new implants are developed, before they eventually can be approved for general use in healthcare.</b></p>​Patients who are suffering from conductive or mixed hearing loss can gain normal hearing with a new implant that replaces the middle ear. Over 200 000 people worldwide have this type of hearing aids that uses the skull bone to transmit sound vibrations to the inner ear via so-called bone conduction.<br /><br />The Bone Conduction Implant (BCI) is a new type of hearing aid with several improved features developed by <span>researchers at Chalmers´ department of signals and systems, in collaboration with </span><span><span>Senior Physician <span style="display:inline-block"></span></span></span><span>Måns Eeg-Olofsson and his team at the ENT department, Sahlgrenska University Hospital.</span> The first patient received the BCI implant in December 2012 in Gothenburg, and it is today worn by 16 patients in a clinical study.<br /><br /><strong>Milestone celebrated </strong><br />Recently, a milestone was reached on the way to the goal of launching the BCI to the market in the future. The bone conduction implant has been kept “listening” to radio in an age-acceleration test chamber that accelerates the exposure time with a factor of approximately six times. <br /><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ny%20unik%20benförankrad%20hörapparat%20klarade%20långtidstest/Bo_Håkansson_320px.jpg" alt="" style="margin:5px" /><br />“The performance of the implant has been verified and monitored corresponding to ten years of normal usage time for patients who are using the hearing aid for eight hours on a daily basis”, says Professor Bo Håkansson, originator of the bone conduction hearing aids and a pioneer in the field with 40 years´ research experience.<br /><br />The long term endurance test shows that the life span of the implant is longer than the desired minimum time for implants in the human body, often considered to be ten years.<br /><br /><br /><br /><br />“Once a month, for twenty months, we have monitored the implant performance at different frequencies”, says PhD-student Karl-Johan Fredén Jansson, who is responsible for these validations, which also is an important part of his coming doctoral thesis. “We are pleased to note that we during this time haven’t seen any impairment in the implant function.”<br /><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ny%20unik%20benförankrad%20hörapparat%20klarade%20långtidstest/Karl-Johan-Freden-Jansson_320px.jpg" alt="" style="margin:5px" /><br /><strong><br />Simulating conditions in the human body</strong><br />The test chamber was constructed about two years ago by the student Helga Jóna Harðardóttir, who started the project during her master thesis project at Chalmers.<br /><br />To simulate the real conditions in the human body, the temperature in the test chamber is kept at 37 degrees Celsius. The Swedish national radio P1 has proved to be the best radio channel to use in the test, since the broadcasts resemble a good mix of the sounds you are exposed to during an ordinary day at work, comprising both spoken words and other sounds.<br /><br />The researchers can whenever they want connect and listen how the sound would be perceived inside of the head of the patient using the implant, through a so called skull simulator.<br /><br /><strong>Valuable meetings with patients </strong><br />Evaluations are also done concerning how the patients in the study experience the life with their new hearing aid and they regularly come to Chalmers to do follow-up visits and hearing tests.<br /><br />”So far we have received good responses from the participants and haven’t had any serious complications”, says Professor Bo Håkansson. “To meet grateful patients, who feels a higher quality of life, gives us a very strong motivation to carry on with our work.”<br /><br /><strong>Heading for long term goal</strong><br />In the meantime the implant continues to “listen” to radio in the test chamber. The aim is to collect more data, which gives information about how the implant reacts if the hearing aid is used for more years and over eight hours on a daily basis.<br /><br />The long term goal is to get CE-mark in the EU and approval from the US Food and Drug Administration, FDA. Important information to qualify for these requirements, concerns for example safety issues towards the patient, technical function and hearing rehabilitation. These are essential steps on the way of launching the BCI as a new hearing aid for general use in healthcare, and to offer improved hearing rehabilitation for more people.<br /><br />Text: Yvonne Jonsson<br />Photo: Oscar Mattsson<br /><br /><br /><strong>This is how the Bone Conduction Implant (BCI) works</strong><br /><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ny%20unik%20benförankrad%20hörapparat%20klarade%20långtidstest/BCI-implantat+processor_i_hand_320px.jpg" alt="" style="margin:5px" />The implant is slightly less than six centimeters long. By a surgical procedure, it is implanted in the skull bone under the skin at a position behind the ear. Sound is transmitted wirelessly from an externally worn sound processor to the implant by an induction link, comprising one transmitter coil in the sound processor and one receiver coil in the implant. The patient can easily attach or remove the sound processor from the head as it is magnetically attached over the implant. <br /><br />The audio signal is transmitted to a tiny quadratic loudspeaker anchored to the bone near the auditory canal.
