This is Chalmers' contribution to a future method that will make it possible to safely test drive vehicles, even without a driver on board.</b></p>​<span style="background-color:initial">Those who have chosen a test driver profession not only need to have a high tolerance threshold for long and uncomfortable work shifts behind the wheel. It is as important to have the ability to detect early signs that a significant part of the vehicle is becoming malfunctioning.</span><div><br /><span style="background-color:initial"></span><div>But how can this safety-critical professionalism be passed on to a future when more and more vehicles become self-driving? Is it possible to mix self-driving and driver-controlled vehicles on one and the same test track? How is safety affected when there is no longer anyone on board who can break or steer to the side to prevent an accident? These are some of the issues behind ETAVEP (Enablers for testing autonomous vehicles at existing testing grounds), a research project co-financed by Vinnova program Vehicle Strategic Research and Innovation, which takes a closer look at the challenges in vehicle testing that arise as cars become increasingly autonomous.</div> <div><br /></div> <div>Researchers from Chalmers, together with the truck manufacturer AB Volvo and the car manufacturer Volvo Cars, have focused on the part of the project that deals with the fact that vehicles must be able to be monitored even when a person's ears, sensory organs and experience are not in place. </div> <div><br /></div> <div>The task has thus been to create an automated system that in real time can give an indication that some mechanical component that is important for safety is about to fail.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/ETAVEP/Tomas_McKelvey-1.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Tomas McKelvey, Professor in Signal processing at the Department of Electrical Engineering and, who has led the research within the subproject, explains:</div> <div><br /></div> <div>&quot;The problem lies in how to best monitor a vehicle when you do not know in advance what it is that will break.”</div> <div><br /></div> <div>He emphasises that one cannot rely on the systems that need to be on board once the self-driving vehicles come out in normal traffic - this is because test drives can take place even in earlier phases of vehicle development before the autonomous functions are reliable.</div> <div><br /></div> <div>You could say that the approach chosen is somewhat reminiscent of how the human perception works - we are usually quite good at paying attention to sensory impressions that deviate from what is expected. </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/ETAVEP/Picture-11_340x305.jpg" class="chalmersPosition-FloatLeft" alt="" style="background-color:initial;margin:5px" />A few dozen accelerometers, placed in strategically important places in the vehicle, have been allowed to act as the system's tactile rod. They register how the vibrations that occur in the engine and in contact with the road surface propagate further out into the body and components.</div> <div><br /></div> <div>“Our hypothesis has been that the nature of the vibrations will change when an error occurs on board and that the changes can be registered with the help of these instruments.” </div> <div><br /></div> <div>To prevent a changed road surface from triggering a &quot;false alarm&quot;, some of the sensors, located near the vehicle's wheels, are used to register the input signal. The rest of the instruments should then be able to pick up such changes that are due to faults on board.</div> <div><br /></div> <div>But to know how a broken car vibrates, an automatic system must first learn how a faultless car behaves. So, the collection of this data became the researchers' first task once the instrumentation of the two test vehicles - a heavy truck and a passenger car - was completed. </div> <div><br /></div> <div>&quot;We achieve this by creating a so-called transfer function, a mathematical description of how different parts of the car move together.”</div> <div><br /></div> <div>He adds that this type of analysis creates &quot;an awful lot of data&quot; - it is about 1,500 so-called complex numbers (numbers that have a real part and an imaginary part) per second. </div> <div><br /></div> <div>&quot;From these data, we build a stochastic model that describes the normal case, where each value is allowed to have a certain variation.”</div> <div><br /></div> <div>In the next stage, the researchers let the two test cars roll on the same surface as before, but now with various intentional errors introduced in the vehicles. </div> <div><br /></div> <div>Data from the accelerometers were analysed again - this time with the hope that the monitoring system could perceive changes in vibrations as an indication of the faults. </div> <div><br /></div> <div>Did it work? </div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/ETAVEP/Picture-4_750x340px.jpg" alt="" style="margin:5px;width:685px;height:314px" /><br /><br /><span style="background-color:initial">&quot;Yes,</span><span style="background-color:initial"> the system could quite easily detect errors - even such errors that according to the test drivers are very difficult to detect.”</span><br /></div> <div><br /></div> <div>&quot;Only one of the intentional faults did the system bite on - a nut on a shock absorber attachment that had been loosened a few turns on the heavy truck. But on the other hand, it was a fault that the test drivers could not feel either.”</div> <div><br /></div> <div>The automatic monitoring system that the Chalmers researchers have developed reacts to something being wrong - but the system cannot tell exactly where the fault is. </div> <div><br /></div> <div>&quot;You could probably work on this fur<span style="white-space:pre"> </span>ther, but we have not had time for that in this study. From a safety point of view, the most important thing is to find out that an error has occurred, so that the vehicle can be taken off the test track.”</div> <div><br /></div> <div>The practical experiments with the monitoring system took place last autumn at Volvo's test track in Hällered outside Borås, where the test facility AstaZero, run by Chalmers and RISE, is also located.</div> <div><br /></div> <div>In addition to monitoring vehicle status, which the Chalmers researchers worked on in this sub-project, ETAVEP also includes methods and systems for traffic monitoring and vehicle control, including using radar, light radar (lidar) and camera surveillance. The systems are linked to communication based on 5G technology. </div> <div>According to Tomas McKelvey, the methodology developed within the overall ETAVEP project is the first among test facilities around the world, when it comes to allowing autonomous and driver-controlled vehicles to coexist. </div> <div><br /></div> <div>&quot;The hope is that the methods developed will become a kind of international standard for test tracks.” </div> <div><br /></div> <div>He adds that representatives of other test facilities have shown great interest in the project. The reason is that there are both economic and environmental benefits from being able to use existing facilities, rather than having to sacrifice land and resources to build new test tracks only for autonomous vehicles. </div> <div><br /></div> <div>&quot;In addition, the test driver's working life as it looks today is very physically stressful. So even from that aspect there is a sustainability perspective,” Tomas McKelvey concludes.</div> <div><br /></div> <div><br /></div> <div>Written by: Sandra Tavakoli</div> <div><br /></div> <div><br /></div> <div><strong>Facts about the research: </strong></div> <div><ul><li>The two-year research project ETAVEP (Enablers for testing autonomous vehicles at existing testing grounds) is part of the Vinnova program Vehicle Strategic Research and Innovation. </li> <li>In addition to AB Volvo and Volvo Cars and Chalmers, the project participants consist of the research institute RISE, the test facility AstaZero and the research company SafeRadar. </li> <li>Final report from the project will be written in the spring. </li> <li>In addition to Tomas McKelvey, those who worked on the sub-project on automatic monitoring have been Project Manager Patrik Nordberg from Volvo Cars and Daniel McKelvey, a student in Engineering mathematics and computational science at Chalmers, who had the project as his master thesis. </li></ul></div> <div><br /></div> <div><strong>Facts / Accelerometer</strong></div> <div>An instrument that measures acceleration in relation to free fall, often in three dimensions, and which is found in every modern mobile phone, among other things.

Researchers at Chalmers University of Technology, Sweden, have developed a new form of AI, which, by observing human behavior, can adapt to perform its tasks in a changeable environment. The hope is that robots which can be flexible in this way will be able to work alongside humans to a much greater degree.​</b></p><div>“Robots that work in human environments need to be adaptable to the fact that humans are unique, and that we might all solve the same task in a different way. An important area in robot development, therefore, is to teach robots how to work alongside humans in dynamic environments,” says Maximilian Diehl, Doctoral Student at the Department of Electrical Engineering at Chalmers University of Technology and main researcher behind the project.</div> <div><br /></div> <div>When humans carry out a simple task, such as setting a table, we might approach the challenge in several different ways, depending on the conditions. If a chair unexpectedly stands in the way, we could choose to move it or walk around it. We alternate between using our right and left hands, we take pauses, and perform any number of unplanned actions.</div> <div><br /></div> <div>But robots do not work in the same way. They need precise programming and instructions all the way to the goal. This approach makes them very efficient in environments where they constantly follow the same pattern, such as factory processing lines. But to successfully interact with people in areas such as healthcare or customer facing roles, robots need to develop much more flexible ways of working.</div> <div><br /></div> <div>“In the future we foresee robots accomplish some basic household activities, such as setting and cleaning a table, placing kitchen utensils in the sink, or help organizing groceries,” says Karinne Ramirez-Amaro, Assistant Professor at the Department of Electrical Engineering.</div> <div><br /></div> <div>The Chalmers University researchers wanted to investigate whether it was possible to teach a robot more humanlike ways to approach solving tasks – to develop an ‘explainable AI’ that extracts general instead of specific information during a demonstration, so that it can then plan a flexible and adaptable path towards a long-term goal. Explainable AI (XAI) is a term that refers to a type of artificial intelligence where humans can understand how it arrived at a specific decision or result.</div> <div><br /></div> <div style="font-size:16px"><strong>Teaching a robot to stack objects under changing conditions</strong></div> <div><br /></div> <div>The researchers asked several people to perform the same task – stacking piles of small cubes – twelve times, in a VR environment. Each time the task was performed in a different way, and the movements the humans made were tracked through a set of laser sensors.</div> <div><br /></div> <div>“When we humans have a task, we divide it into a chain of smaller sub-goals along the way, and every action we perform is aimed at fulfilling an intermediate goal. Instead of teaching the robot an exact imitation of human behavior, we focused on identifying what the goals were, looking at all the actions that the people in the study performed,” says Karinne Ramirez-Amaro.</div> <div><br /></div> <div>The researchers' unique method meant the AI focused on extracting the intent of the sub-goals and built libraries consisting of different actions for each one. Then, the AI created a planning tool which could be used by a TIAGo robot – a mobile service robot designed to work in indoor environments. With the help of the tool, the robot was able to automatically generate a plan for a given task of stacking cubes on top of one another, even when the surrounding conditions were changed. </div> <div><br /></div> <div>In short: The robot was given the task of stacking the cubes and then, depending on the circumstances, which changed slightly for each attempt, chose for itself a combination of several possible actions to form a sequence that would lead to completion of the task. The results were extremely successful.</div> <div><br /></div> <div>&quot;With our AI, the robot made plans with a 92% success rate after just a single human demonstration. When the information from all twelve demonstrations was used, the success rate reached up to 100%,&quot; says Maximilian Diehl.</div> <div><br /></div> <div>The work was presented at the robot conference IROS 2021, one of the world’s most prestigious conferences in robotics. In the next phase of the project, the researchers will investigate how robots can communicate to humans and explain what went wrong, and why, if they fail a task.</div> <div><br /></div> <div style="font-size:16px"><strong>Industry and healthcare</strong></div> <div><br /></div> <div>The long-term goal is to use robots in the industry to help technicians with task that could cause long-term health problems, for example tightening bolts/nuts on truck wheels. In healthcare, it could be tasks like bringing and collecting medicine or food. </div> <div><br /></div> <div>“We want to make the job of healthcare professionals easier so that they can focus on tasks which need more attention,” says Karinne-Ramirez Amaro.  </div> <div><br /></div> <div>&quot;It might still take several years until we see genuinely autonomous and multi-purpose robots, mainly because many individual challenges still need to be addressed, like computer vision, control, and safe interaction with humans. However, we believe that our approach will contribute to speeding up the learning process of robots, allowing the robot to connect all of these aspects and apply them in new situations”, says Maximilian Diehl.</div> <div><br /></div> <div>By: Sandra Tavakoli and Karin Wik</div> <div><br /></div> <div><div>The research was carried out in collaboration with with Chris Paxton, a research scientist at NVIDIA.

I was the very first assistant professor recruited from abroad to Chalmers’ Transport Area of Advance. Over these more than ten years, I have really enjoyed growing up in, and contributing, to the Transport Area of Advance. The mentorship, the internal and external networks and the leadership have all been very valuable“, says Balázs Kulcsár.</div> <div><br /></div> <div><strong>What experiences will you bring?<br /><br /></strong></div> <div>“Firstly, I know well from my own experience how it is to be a researcher within the Transport Area of Advance and what research support means. Secondly, since I first arrived at Chalmers, I have experienced how vital it is to belong to this kind of strong network that embraces researchers with connected interests. This is a message I have emphasized in different national and international forums and through research, teaching and evaluations. With my experiences, I believe I can continue to contribute to the Transport Area of Advance but now at different level.”</div> <div><br /></div> <div><strong>What opportunities and priorities do you see going forward?<br /><br /></strong></div> <div>“I have many ideas on how to continue to develop the Area of Advance. One important thing to note is that transportation research currently is witnessing a paradigm shift. Transportation is becoming a sustainable mobility service requiring the synergy of complex research profiles. This, more than ever, requires a strong network of collaborative researchers,” says Balázs.</div> <div><br /></div> <div>“Taking a wider perspective, transport research projects contribute to Chalmers’ excellence in Sweden and internationally. Inspiring our researchers to reach higher and higher with funding from Transport Area of Advance while introducing them to the mobility service concept is my aim. Hopefully my journey can serve as an inspiration to other researchers.”</div> <div><br /></div> <div><strong>What is your view on collaboration with other Areas of Advance?<br /><br /></strong></div> <div>“Research trends call for more and more interdisciplinarity approaches. This is true for transportation sciences as well, where the vehicle is considered a central part of a mobility service. However, it is not the only part of the service. Therefore, I hope to collaborate with other Areas of Advance to create quality-oriented research in the transportation themes covered by the Area of Advance and to add value to each other.”</div> <div><br /></div> <div>“Additionally, to continue building strong strategic partnerships outside Chalmers is vital to reach our objectives”, says Balázs Kulcsár.</div> <div><br /></div>Thu, 03 Mar 2022 18:00:00 +0100​Time to inaugurate all-wise computer resource<p><b>​Alvis is an old Nordic name meaning &quot;all-wise&quot;. An appropriate name, one might think, for a computer resource dedicated to research in artificial intelligence and machine learning. The first phase of Alvis has been used at Chalmers and by Swedish researchers for a year and a half, but now the computer system is fully developed and ready to solve more and larger research tasks.​</b></p><br /><div><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/300x454_Alvis_infrastructure_1.png" alt="A computer rack" class="chalmersPosition-FloatRight" style="margin:10px;width:270px;height:406px" />Alvis is a national computer resource within the <strong><a href="">Swedish National Infrastructure for Computing, SN​IC,</a></strong> and started on a small scale in the autumn of 2020, when the first version began being used by Swedish researchers. Since then, a lot has happened behind the scenes, both in terms of use and expansion, and now it's time for Chalmers to give Swedish research in AI and machine learning access to the full-scale expanded resource. The digital inauguration will take place on <span style="font-weight:normal"><a href="/en/areas-of-advance/ict/calendar/Pages/Alvis-inauguration-phase-2.aspx">February 25, 202</a>2.</span></div> <div><br /></div> <div><b>What can Alvis contribute to, then? </b>The purpose is twofold. On the one hand, one addresses the target group who research and develop methods in machine learning, and on the other hand, the target group who use machine learning to solve research problems in basically any field. Anyone who needs to improve their mathematical calculations and models can take advantage of Alvis' services through SNIC's application system – regardless of the research field.</div> <div><span style="background-color:initial">&quot;Simply put, Alvis works with pattern recognition, according to the same principle that your mobile uses to recognize your face. What you do, is present very large amounts of data to Alvis and let the system work.

A new type of bone conduction speaker, easily attached behind the ear, can make the diagnosis more efficient and safer – especially for patients who also suffer from hearing problems. The technology has been developed by researchers at Chalmers University of Technology, Sweden, and is now ready for manufacturing.</b></p>​<span style="background-color:initial">Hearing and balance are closely related. For patients with dizziness, this relationship is used for diagnosis. Commonly, a ‘VEMP’ test (Vestibular Evoked Myogenic Potentials) is performed. A VEMP test uses loud sounds to evoke a muscle reflex contraction in the neck and eye muscles, triggered by the vestibular system – the system responsible for our balance. Instead, the Chalmers University researchers are using bone-conducted sounds to achieve better results.</span><div><br /><span style="background-color:initial"></span><div><span style="background-color:initial"></span><div><img src="/en/departments/e2/news/Documents/Bo%20Håkansson2.jpg" alt="Bo Håkansson2.jpg" class="chalmersPosition-FloatLeft" style="margin:5px;width:125px;height:188px" />&quot;We have developed a new type of vibrating device called B250 that is placed behind the ear of the patient during the test,&quot; says Bo Håkansson, a professor in the research group 'Biomedical Signals and Systems' at Chalmers. </div> <div><br /></div> <div>“The vibrating device is small and compact in size and optimised to provide an adequate sound level for triggering the reflex at frequencies as low as 250 Hz, which we have found to be optimal for VEMP stimulation. Previously, no vibrating device has been available that was directly adapted for this type of test of the balance system.”</div> <div><br /></div> <div>In bone conduction transmission, sound waves are transformed into vibrations through the skull, stimulating the cochlea within the ear, in the same way as when sound waves normally go through the ear canal, the eardrum and the middle ear. This can be used in various technologies, and Bo Håkansson has over 40 years of experience in this field – he has previously developed hearing aids using this technology.</div> <div><br /></div> <div><strong>Dizziness a common problem in older patients</strong></div> <div>Every other person over 65 year suffer from dizziness, but the causes can be difficult to diagnose for several reasons. In 50 precent of those cases, dizziness is due to problems in the vestibular system. But today's VEMP methods have major shortcomings and can cause hearing loss and discomfort for patients. The VEMP test uses very high sound levels and can in fact cause permanent hearing damage itself. And, if the patient already suffers from certain types of hearing loss, it can sometimes be impossible to draw any conclusions from the test. </div> <div><br /></div> <img src="/en/departments/e2/news/Documents/Karl-Johan%20Freden%20Jansson_400px.jpg" alt="Karl-Johan Freden Jansson_400px.jpg" class="chalmersPosition-FloatRight" style="margin:5px;height:170px;width:170px" /><div>&quot; The previous test was like a machine gun going off next to the ear – with this bone-conduction method it will<span style="background-color:initial"> be much more comfortable. The sound levels to which patients are exposed can be minimised. The test can be performed at 40 decibels lower than today's method, which uses air-conducted sounds through headphones. This eliminates the risk that the test itself could cause hearing damage,” says researcher Karl-Johan Fredén Jansson, who made all the measurements in the project.</span></div> <div><br /></div> <div>“The benefits also include safer testing for children, and that patients with impaired hearing function due to chronic ear infections or congenital malformations in the ear canal and middle ear can still be diagnosed for the origin of their dizziness,” says Bo Håkansson.</div> <div><br /></div> <div>A prototype of the vibrating device was first developed by the researchers in 2018, and it has now been tested and developed in several patient studies that have been published internationally, both with healthy individuals to obtain normal data, and in patients suffering from various types of dizziness. The device is compatible with standardised equipment for balance diagnostics in healthcare, which makes it easy to use. In addition to the benefits for patients, the cost of the new technology is also judged to be lower than the corresponding equipment used today, and discussions are ongoing with companies wishing to commercialise the technology.</div> <div><br /></div> <div><div><strong>B250 can also detect tumors</strong></div> <div>A research group in Germany hopes to be able to use the technology in patients with a benign tumor on the balance organ (Vestibular Schwannom). With B250, you can detect the tumor at an early stage. At Karolinska Institutet, B250 is used to develop a method and with the help of vibrations on the ankle, be able to diagnose patients with so-called &quot;skylight syndrome&quot; who suffer from dizziness problems caused by a hole in the upper arch of the balance organ.</div></div> <div><strong style="background-color:initial"><br /></strong></div> <div><strong style="background-color:initial">More about Diagnostics for Dizziness</strong><br /></div> <div>A common method of diagnosing the cause of dizziness is a VEMP test – Vestibular Evoked Myogenic Potentials. The test uses sound stimulation to evoke a muscle contraction in the neck and eye muscles, triggered by a reflex from the vestibular system – the system that is responsible for our sense of balance. The muscular response is measured and provides information on whether the disorders responsible for the patient’s dizziness are in the vestibular system, or in its pathways to the brain.</div> <div><br /></div> <div>In a traditional vestibular investigation, two variants of VEMP tests are used today: air transmitted sound through headphones or bone conducted sounds via a vibrating device attached to the head. When air transmitted sounds are used, high sound levels are required, which is uncomfortable for the patient and risks hearing damage. For bone conducted sound, the sound levels are lower, but the equipment currently available on the market is large and cumbersome, and therefore difficult to use. The new method uses new transducer technology, is smaller in size and generates bone conducted sound at a lower frequency than has been possible before (around 250 Hz). At this level, the muscle reflexes are more efficiently evoked.</div> <div><br /></div> <div>The muscle contractions in both the neck and the eye muscles are measured using fairly standardised equipment, so it should be easy to start incorporating it into healthcare systems.</div> <div><br /></div> <img src="/en/departments/e2/news/Documents/Sabine_Reinfeldt-2.jpg" alt="Sabine_Reinfeldt-2.jpg" class="chalmersPosition-FloatRight" style="margin:5px;height:170px;width:250px" /><div>​&quot;In the long term, we hope to offer an alternative for bone-guided stimulation of the balance organ in VEMP measurements and especially on improving the diagnosis of dizziness problems in patients who also suffer from conduction obstruction, says Sabine Reinfeldt, Associate Professor at Chalmers Department of Electrical Engineering.<br /></div> <div><br /></div> <div>Skrivet av Sandra Tavakoli och Karin Wik</div> <div><div><br /></div> <div></div></div> <div><strong style="background-color:initial">For more information contact</strong><br /></div> <div>Bo Håkansson</div> <div>Professor in Biomedical Engineering, Department of Electrical Engineering +46-(0)31-772 18 07,</div> <div><br /></div> <div>Karl-Johan Fredén Jansson </div> <div>Researcher, Department of Electrical Engineering , +46- (0)31-772 17 83,​</div></div></div> <div><br /></div> <div><div><span style="font-weight:700">More about the research</span></div> <div>A case series shows independent vestibular labyrinthine function after major surgical trauma to the human <a href="">cochlea</a></div> <div><a href="">“VEMP using a new low frequency bone conduction transducer” </a> </div> <div><br /></div> <div><span style="font-weight:700">Bone Conduction Stimulated VEMP Using the B250 Transducer</span></div> <div><a href=""></a></div> <div><br /></div> <div>The research is performed in cooperation with Sahlgrenska academy at the University of Gothenburg, and the sound companies Ortofon and Interacoustics.

Researchers at Chalmers University of Technology, Sweden, have developed tools to help electric delivery-vehicles navigate strategically to use as little energy as possible. The secret lies in looking beyond just the distance travelled, and instead focusing on overall energy usage – has led to energy savings of up to 20 per cent.​</b></p><div>&quot;We have developed systematic tools to learn optimal energy usage. Additionally, we can ensure that electric<img src="/en/departments/e2/news/Documents/Balazs_Kulcsar_0006,1B.jpg" alt="Balazs_Kulcsar_0006,1B.jpg" class="chalmersPosition-FloatRight" style="margin:5px;width:224px;height:296px" /><br /> vehicles are not running out of battery or charging unnecessarily in complex traffic networks”, says Balázs Kulcsár, Professor at the Department of Electrical Engineering at Chalmers University of Technology.</div> <div><br /></div> <div>The research is the latest result from a joint project between Chalmers and Volvo Group that investigates how electric vehicles can be used for distribution tasks, and the new algorithm for learning and planning the optimal path of electric vehicles is so efficient that it is already being used by Volvo Group.</div> <div><br /></div> <div><strong>Shortest distance not always the least energy</strong></div> <div>In the study, the researchers investigated how a fleet of electric trucks can deliver goods in a complex and crowded traffic network. The challenge is how delivery vehicles carrying household goods, such as groceries or furniture to several different addresses, should best plan their routes. By working out the optimal order to deliver to customers, the vehicles can be driven for as long as possible without needing to interrupt the work to recharge unnecessarily. Route planning for electric vehicles has normally tended to assume that the lowest mileage is also the most efficient, and therefore focused on finding the shortest route as the priority. Balázs Kulcsár and his colleagues focused instead on overall battery usage as the key goal, and looked for routes with the lowest possible energy consumption. </div> <div><br /></div> <div>&quot;In real traffic situations a longer distance journey may require less energy than a shorter one, once all the other parameters that affect energy consumption have been accounted for”, Balázs Kulcsár explains.</div> <div><br /></div> <div><strong>A significant reduction in energy consumption</strong></div> <div><img src="/en/departments/e2/news/Documents/T2021_74571.jpg" alt="T2021_74571.jpg" style="margin:5px;width:680px;height:459px" /><br />Caption: Route planning<br /></div> <div><br /></div> <div>The researchers modeled the energy consumption of distribution trucks moving in a city by looking into many factors; speed, load, traffic information, how hilly different routes were, and opportunity charging points. </div> <div>The energy consumption model was then entered into a mathematical formula, resulting in an algorithm for calculating a route that allows the vehicles to make the deliveries using as little energy as possible. And, if charging is needed out on the road, the vehicle can save time by taking the most energy efficient route to a fast charging point. By accounting for extra factors such as these, the researchers’ new method allowed the vehicles to reduce their energy consumption by between 5 and 20 per cent.</div> <div><br /></div> <div>Because the electric delivery vehicles operate in complex real-world situations, there can often be unforeseen complications that are difficult to account for even if the algorithm is accurate from the beginning. The energy usage forecasts will therefore be further optimised through machine learning, with data collected from the vehicles being sent back to the tool for further input and analysis. </div> <div><br /></div> <div>&quot;Taken together, this will allow us to adapt route-planning to uncertain and changing conditions, minimising energy consumption and ensuring successful urban distribution”, Balázs Kulcsár says.</div> <div><br /></div> <div>Text: Sandra Tavakoli and Karin Wik</div> <div><br /></div> <div><div><strong>More about the research </strong></div> <div><ul><li>​The scientific article <a href="">Dynamic Stochastic Electric Vehicle Routing with Safe Reinforcement Learning</a> has been published in the journal Transportation Research Part E: Logistics and Transportation Review <br /><a href=""></a></li> <li>The article was written by researchers Balázs Kulcsár, Ivan Sanchez and Xiaobo Qu at Chalmers University of Technology in collaboration with Rafael Basso, senior researcher, Volvo Group.</li> <li>​The research has mainly been funded by Vinnova, project ELFORT I-II and co-funded by Chalmers Transport Area of Advance.</li></ul></div></div> <div><strong>Connected literature:</strong></div> <div><div><span style="background-color:initial">Electric Vehicle Routing Problem with Machine Learning for Energy Prediction published in the journal Transportation Research Part B: Methodological, 2021.</span><br /></div> <div><a href="">Paper I</a></div> <div><a href="">Paper II</a></div> <div><br /></div> <a href=""><div>Energy consumption prediction and routing for electric commercial vehicles, PhD Thesis, 2021</div> ​</a><div><strong style="background-color:initial">Contact information</strong><br /></div></div> <div><strong>Balázs Kulcsár</strong>, Professor at the Department of Electrical Engineering, Chalmers</div> <div>​</div>Fri, 10 Dec 2021 08:00:00 +0100 lab will provide better diagnosis and treatment of diseases<p><b>Better diagnosis and treatment of a wide range of diseases – everything from stroke and epilepsy to cancer and trauma.

This means that we will be able to cool with liquid nitrogen instead. Then we can move the sensors closer to the skull and thus capture weaker magnetic signals than has been possible so far,&quot;</span><span style="background-color:initial"> Justin Schneiderman </span><span style="background-color:initial">explains</span><span style="background-color:initial">.</span></div> <div><span style="background-color:initial"><br /></span></div> <div>At the inauguration, it emerged that in the longer term, it is also hoped to be able to use similar detection of magnetic fields to study diseases of the human heart, such as arrhythmias.</div> <div><br /></div> <div>Text: Sandra Tavakoli</div> <div><br /></div> <div><div><strong>Contact information</strong></div> <div><strong>Andreas Fhager</strong>, Associate Professor at the Department of Electrical Engineering and Head of unit at Biomedical Electromagnetics, Chalmers.</div> <div> </div></div>Tue, 30 Nov 2021 10:00:00 +0100
