News: Signaler och system, Electrical Engineering related to Chalmers University of TechnologyMon, 13 Aug 2018 10:30:48 +0200 energy system is being tested at Chalmers<p><b>​This week, for the first time, a unique local marketplace for electricity, heat and cooling is being tested at Chalmers University of Technology, campus Johanneberg. The EU funded initiative is a collaboration between nine local partners and is being held to find new ways towards a fossil-free energy supply system at international level.​</b></p>​The Fossil-free Energy Districts (FED) project has been running for a year and a half, and now the digital, IoT-based marketplace is ready to be connected to campus buildings and tested in a sharp spot. The idea is that buildings that both consume and in some cases produce energy should communicate with each other to avoid energy consumption peaks that are both expensive and bad for the environment.<br /><br />– FED's marketplace is unique in several ways, partly because it connects both electricity, heat and cooling, and partly because it allows smaller players, such as a property owner who has installed solar panels on the roof, to participate in energy trading. At the same time, the system is connected to the larger external network, in our case Göteborg Energi, which provides cover when needed, says Claes Sommansson, FED Project Manager at Johanneberg Science Park.<br /><br />The FED system handles large amounts of data, both from property owners own systems and information such as weather and electricity pricing, and is updated hour by hour. But it is not the property owners themselves who have to process the information. This work is done by smart digital agents who make decisions to optimize energy efficiency in the area. The AI agents are programmed by Ericsson and based on machine learning, which means that they will get better at their job over time.<br /><br /><div>– The biggest advantage of FED is that it's a flexible system and that's something we'll need in the future when the share of energy from renewable sources, like solar and wind, grows. The uneven supply of these sources causes price fluctuations to grow, but the agents in the FED system can for example predict a cold spell and decide to start heating a house before it happens. In this way, you can buy energy at a lower price, before demand increases, but you also avoid burning fossil fuels like gas and oil, says Ericsson's Joakim Pontén, who has been in charge of the IT solution within FED.</div> <div><br />Researchers at Chalmers have done simulations and analysis to build the models that will make the energy system and the marketplace work. <a href="/en/departments/e2/news/Pages/Chalmers-is-becoming-a-unique-marketplace-for-energy.aspx">Read more about the work of the researchers.</a><br /></div> <br />The two property owners at Chalmers, Akademiska Hus and Chalmersfastigheter, are obvious partners in the project, and together they are making significant investments that will be rolled out in the autumn, including several new solar cells and a large battery for storing solar power. The entire FED system is expected to be operational at the end of the year, and the tests being carried out now are an important milestone.<br /><br />– A major challenge has been to connect the property owners' systems with Ericsson and Göteborg Energi's systems. The test week we are now completing is confirmation that our property systems linked to the parent FED marketplace are working well, says Per Löveryd, Innovation Coordinator at Akademiska Hus. <div><img class="chalmersPosition-FloatLeft" alt="Joakim Pontén and Per Löveryd" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Chalmers%20blir%20unik%20handelsplats%20för%20energi/FED-Per-Löveryd-Joakim-Ponten_500px.jpg" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><div><br /></div> <div>Joakim Pontén, Ericsson and Per Löveryd, Akademiska Hus. <br /></div> <div><br /></div> <div><strong>Facts about the project</strong></div> <div>The Fossil-free Energy Districts project, FED, is an innovative effort by the City of Gothenburg to decrease the use of energy and the dependence on fossil fuel in a built environment. A unique local marketplace for electricity, district heating and cooling is being developed together with nine strong partners. The City of Gothenburg, Johanneberg Sciene Park, Göteborg Energi, Business Region Göteborg, Ericsson, RISE Research Institutes of Sweden, Akademiska Hus, Chalmersfastigheter and Chalmers University of Technology are all contributing with their expertise and knowledge to make FED attractive for other European cities as well. Johanneberg Science Park has the coordinating role on behalf of the city. During 2017−2019 the FED testbed will be situated on Chalmers Campus Johanneberg. FED is co-financed by the European Regional and Development Fund through the Urban Innovative Actions Initiative, an initiative of the European Commission for cities to test new solutions for urban challenges.</div> <div><br /></div> <div>Read more:<br /><a href="" target="_blank">About FED on the Johanneberg Science Park website</a><br /><a href="" target="_blank">About FED in Urban Innovative Actions</a><br /><br /></div></div>Wed, 27 Jun 2018 13:00:00 +0200 power electronics in propulsion research project<p><b>​Energimyndigheten, the Swedish Energy Agency, has granted CEVT and Chalmers with 12 MSEK for a development within propulsion technology.</b></p>​<span style="background-color:initial">The project is called iTEM - integrated Transmission and Electric Machine, and is focused within the field of power electronics.

A prototype for wireless charging of city buses is constructed by researchers at Chalmers. The first round of tests is promising.</b></p><div>​<img class="chalmersPosition-FloatRight" alt="Yujing Liu" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Prototypen%20som%20laddar%20bussen%20trådlöst/Yujing_Liu_300x388px.jpg" style="margin:5px;width:200px;height:259px" />In the laboratory at the division of Electric Power Engineering several prototypes for charging electrical vehicles are under construction and testing. <br /><br />In this project, the researchers focus primarily on charging of electric buses operated in cities as they traffic pre-determined routes with specified stops that offer good charging possibilities. Frequent charging allows for substantial reductions in battery size, which lowers the weight and cost of the bus. Alternatively, frequent charging can be used to reduce the depth of discharge, which prolongs the lifetime of the batteries.<br /><br />“The first round of tests on our 50 kW module has been completed in our laboratory and the results are promising so far”, says Yujing Liu, Professor at the department of Electrical Engineering. “The results show a transfer efficiency, from DC to DC, of about 95 percent at the desired power level, across an airgap of 20 centimetres, which is really good.” <br /><br /><strong>Charging the bus from the ground</strong><br />The wireless charging, or inductive power transfer (IPT) as the researchers call it, allows for contactless transfer of power across an air gap that extends from a charging unit in the ground, located at the bus stop, to a similar unit integrated in the vehicle frame of the electric bus. <br /><br />The charging unit in the ground contains a coil which creates a magnetic field. In turn, this magnetic field induces a voltage in a similar coil embedded in the unit placed beneath the vehicle and this induced voltage yields a current that charges the batteries in the electric bus. <br /><br /><span><img class="chalmersPosition-FloatRight" alt="Thomas Rylander" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Prototypen%20som%20laddar%20bussen%20trådlöst/Thomas_Rylander_300x388px.jpg" style="margin:5px;width:200px;height:259px" /><span style="display:inline-block"></span></span>“Essentially, this part of the system is a conventional transformer but, as opposed to a typical transformer, the primary and secondary coils are separated by a relatively large air gap. The gap yields a rather low magnetic coupling and this is compensated for by adding capacitors to the coils such that we get resonance circuits on both the primary and secondary side”, says Thomas Rylander, Professor at the department of Electrical Engineering.<br /><br />To charge the batteries in a bus would require about 200 kW, which will be made possible by connecting charging modules in parallel. <br /><br />The possibility to charge city buses at bus stops, so called opportunity charging, may reduce the size of the battery in the bus, perhaps by as much as 70 percent. About 30 seconds charging at every other bus stop will be enough to keep the batteries at a sufficient charging level – just about the time it takes for passengers to get on or off the bus.<br /><br />Thus, this charging method is different from the one used for the well-known <a href="" target="_blank">Electricity bus trafficking route 55 in Gothenburg</a>. Bus 55 is charged at the end stops using physical connectors on the roof.<br /><br /><strong>Higher efficiency and reduced battery size</strong><br />“The two major challenges that may limit the applications of inductive power transfer in electrical vehicles are the transfer efficiency and the size of the equipment”, says Yujing Liu. “However, the progress in fast-switching power electronics and high-frequency electromagnetic materials has led to new opportunities. We want to explore the benefits of using these kinds of new technology and high-quality materials for reducing losses and the size of the equipment.”<br /><br />Using high electric frequency, it is possible to reduce the magnetic energy and leakage field, which is important for applications in public places like city buses.<br /><br /><span><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Prototypen%20som%20laddar%20bussen%20trådlöst/powerelectronics_transformer_750px.jpg" alt="" style="margin:5px" /><span style="display:inline-block"></span></span><br /><br /><span><em>The pictures show the first prototype of power electronics (to the left) and the primary side transformer (to the right) used for inductive power transfer.

Researchers from Chalmers now have succeeded in developing models to avoid premature aging of batteries, models which can also provide the car with higher performance in terms of shorter charging time, longer mileage and faster acceleration. The research has been rewarded the Volvo Cars Technology Award.</b></p>​An increasing number of car owners consider replacing their fossil-fueled cars with vehicles that are powered entirely or partly by electricity. However, the batteries used in electric vehicles are still comparatively expensive, and there is still a lack of knowledge concerning how the battery life-span can be kept as long as possible.<br /><br />”If you charge lithium-ion batteries correctly and use them in a smart way, you can avoid premature aging of the batteries,” says Torsten Wik, Professor and research group leader in automatic control at Chalmers. “It may sound simple but there are many factors to consider, and it is important to understand how battery life and function are affected.”<br /><br /><strong>More precise and adaptive calculations</strong><br />One of the difficulties is that it is not possible to measure the condition of the battery, it must be calculated. Also, the factors are constantly changing, depending on the temperature, current and cell voltage, as well as the age of the battery. This means that the algorithms must be adaptive in order to constantly adjust to the changing conditions.<br /><br />“The novelty is that the algorithms we have developed constantly depend on the behaviour of the individual battery cells, instead of having to assess the condition of the battery in advance,” says Torsten Wik. “This makes our calculations much more accurate. The capacity of the battery is thus being used more efficiently, and you can avoid putting a strain on the battery that causes it to age prematurely.”<br /><br />Tests show that the battery thus can deliver an additional 10 percent in peak power and that the actual maximum power can be estimated at an accuracy of 2 percent.<br /><br /><span><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Forskarna%20förlänger%20livet%20för%20elbilsbatterier/Drive-E-T5-Twin-Engine-Lithium-ion-battery_400px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:400px;height:222px" /><span style="display:inline-block"></span></span><br /><br /><br /><br /><br /><br /><em>Caption: Lithium-ion batteries are central components in electric cars and have major impact on performance and costs for the future development of electrified vehicles.</em><br /><br /><br /><strong>The automotive industry shows great interest</strong><br />Research has been ongoing since 2012 and is financed by the Swedish Energy Agency. Volvo Cars is participating as a partner, and Björn Fridholm, industrial doctoral student, has an active role in the project.<br /><br />“The battery is the most expensive component in an electric car,&quot; says Björn Fridholm. “If we can use the batteries more efficiently, it would be of great economic significance and a strategically important driving force for the continued development of electric vehicles. The cooperation with Chalmers has built up important knowledge, that we at Volvo Cars now are implementing in our products.”<br /><br />Recently, the researchers in the project have been awarded the Volvo Cars Technology Award in the category Research. The project has so far resulted in three patent applications.<br /><br />“It's great that the results of the research have come to use so quickly,” Torsten Wik says. “Now we proceed to refine our calculation models even more. In the next step, we will focus on what is physically happening in the battery cells. This will require a large extent of computational power in the vehicle, but in return it is likely to provide additional potential of cost reductions and improved performance.<br /><br /><span><em>Text: Yvonne Jonsson</em></span><br /><span><em>Photo: Volvo Cars</em></span><br /><br /><strong>Contact</strong><br /><a href="/en/Staff/Pages/torsten-wik.aspx">Torsten Wik</a>, Professor, Department of Electrical Engineering, Chalmers<br /><a href=""></a><br /><br />Fri, 04 May 2018 10:00:00 +0200 self-driving bus in operation at Chalmers<p><b>​For four weeks, anyone interested can take free rides with a minibus running between Chalmers main entrance and the university library at campus Johanneberg.

The interest in cooperation within the field has increased, both in the automotive industry and from other universities, in the Gothenburg region as well as internationally.<br /><br />&quot;It is great that our research is gaining recognition,&quot; says Jonas Sjöberg. “I have been able to form a research group with young researchers, who have taken on new research challenges in a new and growing field.”<br /><br /><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Aktiv%20trafiksäkerhet%20gav%20Volvostipendium/Jonas_Sjöberg_300px.jpg" alt="Jonas Sjöberg" class="chalmersPosition-FloatRight" style="margin:5px;width:230px;height:300px" />In the justification for the scholarship, it is emphasized that Jonas Sjöberg successfully has developed the field of electromobility and autonomous driving. Together with his research group, and often in cooperation with other researchers at the Department of Electrical Engineering, he has worked with system aspects, dimensioning, modeling and control of hybrid drive lines. The results have enabled more exact calculations of the &quot;best&quot; design for challenges in electromobility and how to control the energy management in the vehicle, which previously relied on rough estimates.<br /><br />One of the industrial PhD student projects that Jonas has been engaged in, within the Intelligent Vehicle Safety System Program, has resulted in a patent, which subsequently has been applied in newer Volvo cars where a system of emergency braking helps avoiding accidents in left-hand turns. <br /><br />His research in recent years has been focused on issues concerning autonomous driving.<br /><br />&quot;What appeals the most to me within this research area is that we constantly are faced with so multifaceted and complex problems, that for every new progress there is always more to understand,&quot; says Jonas Sjöberg. “It is also important to constantly have the interaction between human beings and technology in focus.”<br /><br /><strong>Prize ceremony and seminar</strong><br />On 29 May, the prize ceremony will be held where Jonas Sjöberg is awarded the 2017 Håkan Frisinger scholarship.

The first MOOC (Massive Open Online Course) in the MicroMasters programme introduced by Chalmers University of Technology focuses on the ongoing technology transition. You will not only learn how to design both electric and conventional powertrains, but to analyze their performance.</b></p><p>​– To make you capable of working with many of the interesting challenges in developing future vehicle powertrains, this course will deal with both electric and engine based powertrains, with a focus on how to analyze and design them, says Sven B Andersson who is one of the teachers you will meet in the course.</p> <p>Since the conventional powertrain is dominating today, it makes sense to use this as the starting point for the course &quot;Electric and Conventional Vehicles&quot;. The conventional powertrain has another set of strengths and weaknesses than the electric powertrain. Therefore it is not a question of which powertrain is the best. Rather, it is important to match each vehicle type to a suitable powertrain.</p> <p>– Electric powertrains are becoming more and more used, but also the conventional powertrain is undergoing a strong development, not to mention the electric hybrids. There are several reasons for this, says Anders Grauers who is co-teaching the course. He provides a list of reasons:<br /><br /></p> <ul><li>Concerns for greenhouse gases and air quality in cities have led to more and more stringent emission and fuel economy limits.</li> <li>Lithium Ion batteries have enabled better performance than previous battery technologies.</li> <li>Cost for batteries and electric drive components have dropped drastically in recent years. </li> <li>Also, the first generation of electric vehicles have generally exceeded expectations leaving only a few major concerns, like the cost for providing long driving range and battery life length under harsh conditions. <br /></li></ul> <p><br />– In the ongoing technology transition period, it is important to not only learn how a powertrain is designed now, but to learn methods to analyze and compare different powertrain solution, as the powertrains will continue to develop for many years to come, says Anders Grauers. </p> <p><br /></p> <a href="">Enroll at edX</a><br /><br /><p></p> <h4 class="chalmersElement-H4">Facts about the MOOC Electric and Conventional Vehicles</h4> <div><strong>Start date: </strong></div> <div>1 March 2018</div> <p></p> <p><strong>Teachers: </strong><br /><a href="/en/Staff/Pages/svan.aspx">Sven B.

After having defended his doctoral thesis in high voltage engineering in 1987 he started working at ABB in Västerås. During his 13 years at the company he had several positions and worked as head of research, developing technology for measurements of diagnostics and monitoring of insulation systems and electrical power devices. In addition, he has invented and developed products in power generation. Most known is perhaps the Powerformer, a high voltage generator for connection to the grid without any intermediate transformer.<br /><br /><strong>Developing renewables</strong><br />Since 2000, Mats Leijon is a Professor in electrical science at Uppsala University. He has got about 1500 patents and has published more than 300 scientific articles. Developing renewable energy sources by using waves, wind and tidal currents have become his specialty. In parallel he has started the company Seabased, which plans, builds and installs complete, grid-connected wave parks at sea. Research and demonstration facilities are located outside Lysekil.<br /><br />He is now phasing out part of his many commitments to be able to take on the assignment at Chalmers.<br /><br />&quot;I look forward to combining theory and practice to a larger extent than I have been able to do previously in academia&quot;, says Mats Leijon. “Here at the division of Electrical Power Engineering, there are good laboratory activities.”<br /><br />In his opinion, setting high goals is crucial to success.<br /><br />“First of all, I'm going to familiarise myself with the research activities here, and then apply for funding to do exciting research, but it is still too early to say in what areas this will be.”<br /><br /><strong><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/E2/Profilbilder%20Elkraftteknik/Mats-Leijon_300x300px.jpg" alt="" style="margin:5px;width:250px;height:250px" />Important to do one´s homework</strong><br />“As a researcher, it is important not to limit your mind. One prerequisite is that you have done your homework and have a solid and stable knowledge base founded in basic theory”, Mats emphasises. “That gives you qualifications to take responsibility for development in society.”<br /><br />&quot;In order to implement your ideas, as an engineer, you can´t ignore what is possible to put into practice and what is commercially viable”, he states. “It is important to understand how your own research fits into the big picture.”<br /><br />He sees the conformity within academia as a problem.<br /><br />”People of the same type tend to choose the same type of solutions. The question is then if the right solutions really are highlighted? At Uppsala University, women account for about 40 percent in the field of electrical engineering. Perhaps I have some lessons learnt, that I could bring here”, Mats Leijon concludes.<br /><br />Text: Yvonne Jonsson<br /><br /><strong>Contact: </strong><a href="/en/Staff/Pages/Mats-Leijon.aspx">Mats Leijon</a>, Professor, Department of Electrical Engineering, Chalmers Fri, 16 Feb 2018 08:30:00 +0100 for new paradigm in pulping technology<p><b>​The Arne Asplund Mechanical Pulping Award 2018 has been granted to Professor Anders Karlström, Head of the department Electrical Engineering at Chalmers.</b></p>​The award is given out every two years by Arne Asplund Mechanical Pulping Award Foundation to promote the development of new technology for the manufacture of high-yield pulp. It is awarded in recognition of outstanding achievement in research and development of mechanical pulping technology.<br /><br /><span>“To receive this award is a great honor for me”, Anders Karlström says. “I have been working with this for many years and it feels fantastic to get a confirmation that the struggle really has been worthwhile.”<span style="display:inline-block"></span></span><br /><br />The justification for the award reads as follows: “Based on his deep understanding of the fundamentals of refining in mechanical and chemimechanical pulping, Anders Karlström has initiated a paradigm shift regarding the theory of refining by introducing the entropy model. This new approach offers tools to understand the interplay in the refining zone with regards to refiner operation, plate patterns and the produced pulp quality. These new findings are already in use in several production lines offering a set of possible ways to optimise quality and specific energy input.”<br /><br />The award consists of a gold medal and an honorarium of SEK 25,000. The prize ceremony will take place at the International Mechanical Pulping Conference, IMPC, in Trondheim on 29 May. <br /><br />Regarded as the &quot;Nobel Prize&quot; in the field of mechanical pulping, the Arne Asplund Mechanical Pulping Award was established in 1985 to commemorate the Swedish engineer Arne Asplund’s contribution to the pulp and paper industry worldwide. He was the inventor of the thermomechanical pulping technique, known as the defibrator-method, also called the Asplund-method, for pulping wooden chips.<br /><br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release</a><br /><br /><strong>Contact:</strong> <a href="/sv/personal/Sidor/anders-karlstrom.aspx">Anders Karlström</a>, Professor and Head of the Department Electrical Engineering, Chalmers<br />Thu, 15 Feb 2018 13:00:00 +0100 computers learn how to diagnose brain diseases?<p><b>​Imaging technology has revolutionized healthcare and is widely used for diagnosis before treatment or surgery. Despite these advances, routine clinical MRI data interpretation is mostly performed by medical experts. Is it possible to use deep learning to teach computers to diagnose brain diseases as well as or in some aspect even better than medical doctors?</b></p>​<span><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Kan%20datorer%20lära%20sig%20att%20diagnosticera%20hjärnsjukdomar/Inrene_Gu_200px.jpg" alt="" style="margin:5px" /><span style="display:inline-block"></span></span>Deep learning is about using powerful computers with embedded artificial intelligence to resemble the human brain's way of interpreting new information and draw conclusions in relation to what is already known. The difference is that computers, amongst other things, are able to analyse much larger amounts of data, which can be used to find better methods for solving difficult mathematical and technical problems.<br /><br />“Using a large amount of brain image data, deep learning methods can be used to find characteristic features related to some diseases, and provide powerful diagnostic tools to medical doctors”, says Irene Gu, Professor in the signal processing group at Chalmers. <br /><br />So far, only preliminary research work on deep learning is reported in the medical area. In computer vision, deep learning has reached or even surpassed human performance when it comes to face recognition. <br />Recently, Irene Gu has started a research initiative on brain image analytics using deep learning methods in close collaboration with medical doctors at Sahlgrenska University Hospital and several students. The question is: Would it be possible for artificial intelligence technology to diagnose Alzheimers’ disease, or to find brain tumors’ grading, by only using a large amount of brain image data?<br /><br />“We have obtained some initial promising results. Our ambition is to reach the performance of medical experts and yet in much simpler ways”, says Irene Gu.<br /><br /><strong>Detection of Alzheimer’s disease</strong><br />Alzheimer’s disease is a chronic neuro-degenerative disease currently incurable, its cause is not yet completely understood. According to WHO’s statistics in 2015, roughly 30 million people in the world suffer from Alzheimer’s. The symptoms consist of disorientation, language difficulties, memory loss, mood swings and many more. Early diagnosis and treatment can potentially slow down the development of the disease.<br /><br />Brain scans by magnetic resonance imaging, MRI, is a commonly used diagnostic method for detecting Alzheimer’s disease. This is often used in combination with other diagnostic methods involving a set of clinical exams, by observing the progression of dementia symptoms.<br /><br />“In this project, two dedicated deep learning methods, simple yet effective, have been developed for detection of Alzheimer’s disease. One method is based on 3D convolutional networks, another on 3D multiscale residual networks. We use a large amount of brain MRI scans to learn our computers the features of Alzheimer’s disease, and subsequently to detect Alzheimer’s patients from unseen scans”, Irene Gu explains. <br /><br />The study involved 340 subjects and about 1200 MR images, obtained from a public available dataset, Alzheimer’s Disease Neuroimaging Initiative (ADNI).<br /><br />“The proposed schemes have yielded high accuracies. For example, one method has reached an accuracy of 98,74 % on previously unseen MRI scans, and 90,11 % from MRI scans of unseen patients in the study. This almost reaches the highest state-of-the-art research results”, Irene Gu says. “This indicates that the method that we have developed is useful in this type of studies.”<br /><br />One of the projects was conducted by <a href="">Mahmood Nazari and Karl Bäckström as a master's thesis project</a>.<br />A paper submitted on this work has recently been accepted by IEEE International Symposium on Biomedical imaging (ISBI) 2018. Another MSc project is still ongoing.<br /><br /><strong>Brain tumor grading</strong><br />Encouraged by the good deep learning results using MR images, Irene Gu has started another project based on similar technology, performed by Karl Bäckström in 2017. <br /><br />“Thanks to the interest in computer-assisted brain tumor diagnostics shown by medical doctors at Sahlgrenska, and seed funding from the department of Electrical Engineering at Chalmers, we could perform a study on brain tumor (glioma) grading using deep learning”, says Irene Gu.<br /><br />A glioma is a type of tumor that starts in the glial cells of the brain or the spine. Gliomas comprise about 30 percent of all brain tumors and central nervous system tumors. About 80 percent of all malignant brain tumors are gliomas.<br /><br />The broad international collaboration networks, which the medical doctors are engaged in, have provided the researchers with brain tumor datasets from USA, France and Austria.<br />We have already obtained some promising results, though on relatively small datasets”, says Irene Gu. “Now we are conducting further in-depth research, where more students and researchers from Chalmers participate in close collaboration with Sahlgrenska University Hospital.”<br /><br />Text: Yvonne Jonsson<br /><br /><strong>More information</strong><br /><a href="/sv/personal/Sidor/Irene-Yu-Hua-Gu.aspx">Irene Gu</a>, Professor, Department of Electrical Engineering, Chalmers<br /><a href=""></a><br /><a href=""></a><br /><a href="/en/departments/e2/research/Signal-processing-and-Biomedical-engineering/Pages/Image-and-video-analysis.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about computer vision and medical image analysis</a><br />Thu, 08 Feb 2018 08:00:00 +0100
