But in order for us to be able to use them in a controlled way and maximise utility, we need to understand how they work and what differentiates bacterial communities – something that has previously been difficult to calculate. With the help of a new methodology, researchers from Chalmers have found the solution.</b></p><div>​Bacteria are found almost everywhere, both in nature and in the built environment. Many of them help us stay healthy and some make us sick. Some of them perform important work in our infrastructure, such as in a sewage treatment plant where the function is completely dependent on microorganisms breaking down pollutants, and in drinking water production where microbial growth plays an important role for water quality. But bacteria can also create problems; when it comes to concrete and metal structures, corrosion caused by microorganisms leads to enormous costs for society.<br /><br /></div> <div>  – To make the bacteria work for us, we must design systems that enable them to do what we want. To do that we need to understand the relationships between the systems we design, the bacterial communities that develop and the functions they perform, says Oskar Modin, Professor at the Department of Architecture and Civil Engineering.    </div> <div> </div> <h3 class="chalmersElement-H3">Hill numbers create order in the jumble of indices    </h3> <div> </div> <div>Oskar Modin and his colleagues are now presenting a method for assessing the difference in composition between different communities of microorganisms. The method is described in a recently published article in the scientific journal Microbiome.</div> <div> </div> <div>  – When we develop measures and techniques, we need to understand how they affect the microbial composition. This is usually done using mathematical indices that describe the differences between two microbial communities. There are a number of indices and different researchers have their favorites.    </div> <div> </div> <div>With the study &quot;Hill-based dissimilarity indices and null models for analysis of microbial community assembly&quot;, the research group has tried to bring order to the index chaos. The researchers show that for some data, completely different conclusions are reached depending on which indices they choose to use, but what they now also have been able to show is that there is a solution to the problem.</div> <div> </div> <div>  – By analyzing their data with a family of indices that are based on something called Hill numbers, researchers can draw robust conclusions. We have also developed a freely available software that we and other researchers can use to calculate this type of index, Oskar continues.    </div> <div> </div> <h3 class="chalmersElement-H3">Well-needed methodology  </h3> <div> </div> <div>The results from the group's research are an important piece of the puzzle in order to be able to develop methods for controlling the composition and function of the complex microbial communities that occur in the built environment.</div> <div> </div> <div>  – Right now we are running projects that aim to improve the function of sewage treatment processes and understand corrosion of concrete in tunnels. The new methodology we have developed will give us significantly better opportunities to interpret data from experiments and samples, Oskar Modin concludes.</div> <div> </div> <div>The paper &quot;Hill-based dissimilarity indices and null models for analysis of microbial community assembly&quot; is available in the journal Microbiome: <a href=""><br /></a></div> <div><br /></div> <div><em>The study was performed at the division of Water Environment Technolgy, Department of Architecture and Civil Engineering at Chalmers and University of Gothenburg.<br /></em></div> <div><br /><em></em></div> <div>Text: Oskar Modin / Catharina Björk<br /><br />Contact: <br /><a href="/en/Staff/Pages/oskar-modin.aspx">Professor Oskar Modin</a><br />  Ph. +46 31 7722138 </div>Thu, 17 Sep 2020 00:00:00 +0200 saves Swedish water from oil leakage<p><b>​Some of the 30 most environmentally hazardous wrecks in Swedish water have been investigated and recovered on 360,000 litres of oil during 2017-2019. To prioritize among the wrecks and carry out oil recovery operations where they are most useful, the Swedish Agency for Marine and Water Management (SwAM) has used the risk assessment tool VRAKA, which was developed by Chalmers.</b></p><p>​There are about 17 000 shipwrecks along the coasts of Sweden and the Swedish Maritime Administration, in collaboration with among others Chalmers and SwAM classified 300 of them as hazardous for the environment. About 30 of the shipwrecks pose an acute environmental threat. They contain large amounts of oil that may leak. Shipwrecks leaking oil pose risk to marine life in Swedish waters. Organisms living in the vicinity of the shipwreck are mainly affected but the oil can also spread to other areas with the water currents. </p> <p><br /></p> <p>SwAM has since 2016 had the responsibility to coordinate the investigations and the recovery of oil and ghost nets (old fishing gear that has remained in the sea and lakes that can continue to fish and catch birds, and other marine animals) from shipwrecks. With the help of Chalmers model, they have been able to prioritize among the wrecks. </p> <p><br /></p> <p>“Before we decide which shipwreck to be recovered from oil, we can use the model to estimate the probability of a leak, the volume of oil in the wreck and where the oil is likely to end up in case of an oil leakage” says Fredrik Lindgren, an analyst at SwAM who previously worked on VRAKA during his doctoral studies at Chalmers. </p> <p></p> <h2 class="chalmersElement-H2"><span>To date, 360,000 litres of oil have been </span><span>recovered </span></h2> <p></p> <p><span style="background-color:initial">Since 2017, the model has been used for investigation and oil recovery operations of the six wrecks Thetis, Skytteren, Sandön, Hoheneichen, Lindesnäs and Finnbirch. They are all close to sensitive natural areas where oil leaks could have major, negative impacts on the environment, outdoor life and tourism. </span></p> <p><span style="background-color:initial"><br /></span></p> <p><span style="background-color:initial">Sandön and Hoheneichen proved to be empty of oil but from Thetis, Lindesnäs and Finnbirch they managed to recover a total of about 360,000 litres of oil and a large amount of ghost net. From Thetis, they also manage to recover 12 tonnes of purse seine (a kind of fishing gear) and during the recovery operation of Lindesnäs, a 46-meter long ghost net was found which was stuck to the wreck. The ghost net was recovered and left ashore for recycling or destruction. </span></p> <p><span style="background-color:initial"><br /></span></p> <p><span style="background-color:initial">The purpose of the investigation of Skytteren was, among other things, to get data to VRAKA for assessment. SwAM's assessment, however, was that an oil recovery operation is very likely to cost more than SwAM's annual budget for environmentally hazardous shipwrecks in Swedish waters. SwAM has requested funding from the government to increase the budget during a financial year, so that they can recover oil from Skytteren as well. </span></p> <p><span style="background-color:initial"><br /></span></p> <p><span style="background-color:initial">From 2018, SwAM was granted SEK 25 million per year until 2027 for research and oil recovery operations. Starting in 2020, the budget is SEK 30 million per year. VRAKA made the funding possible. Carrying out oil recovery operations is costly, from five to hundreds of millions. It is important to make qualified assessments of which wrecks that should be prioritized for oil recovery operations. VRAKA made the prioritization possible and SwAM can now use the funds to make the greatest environmental benefit by removing the threats to the environment from the wrecks that pose the greatest risk.</span></p> <p><span style="background-color:initial"><br /></span></p> <p><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/eulogo.jpg" class="chalmersPosition-FloatLeft" alt="Logotypes from the EU" style="margin:5px" /><br /><br /><br /></span></p> <p></p>Fri, 29 May 2020 08:00:00 +0200 virtual kick-off for the Digital Twin Cities Centre<p><b>​​With over 80 participants representing 30 partners from academia, industry and the public sector, the new Digital Twin Cities Centre (DTCC) was launched in a virtual kick-off event.</b></p><div>Due to the Covid-19 situation, the kick-off took place in the form of a large video conference. <br /></div> <div><br /></div> <div><div> – We were looking forward to meeting physically to really engage in discussions, but under these circumstances we all have to change the way we work and luckily we are well prepared to do most DTCC activities online”, says Bernd Ketzler, Centre Coordinator.  </div> <div> </div> <div>Besides introducing all partners to the operations of the centre, the main purpose of the event was to start the discussions on concrete research activities.

This is normal and usually not dangerous, as the reinforcement prevents the cracks from growing too much. However, these cracks open up the inside of the structure for potentially harmful substances, which can cause corrosion of the reinforcement. This negatively affects the durability of the structure and is highly undesired from the sustainability point of view. Unfortunately, we cannot totally prevent cracking. We would therefore like to be able to model the cracking process, to be able to predict and control crack widths.</div> <div><br /></div> <div>Even though the actual physical phenomena involved in the cracking process are quite complicated, models exist which can give us accurate predictions. These models simulate what's happening to the material when forces, like e.g., gravity or traffic loads, act on it. In practice, we create computer models of the engineering structures we want to analyse. To facilitate the computations, the computer model is divided into small pieces called finite elements. Cracks can have lengths in the order of decimetres, and are thus much smaller than the structure, which usually ranges from tens to hundreds of metres. In terms of crack modelling, this means that the finite elements must also be very small, which results in very large computer models requiring a long time to produce results. Fortunately, there exist multiscale modelling techniques, which are able to provide detailed small-scale results even if the structure is modelled with fairly large finite elements. </div> <div><br /></div> <div>In this thesis, steps are taken to extend the existing multiscale modelling techniques to reinforced concrete structures. This way, detailed results such as crack widths and patterns can be obtained even for very large structures such as bridges or nuclear reactor containment buildings. More specifically, this is achieved by analysing the material response at different length scales, and connecting these scales to each other in an appropriate way. Additionally, thanks to parallel computing, the methods proposed in this thesis can potentially shorten the time it takes to analyse reinforced concrete structures with computer models.</div></div> <div><br /></div> <div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the thesis</a></div> <div><a href="/en/staff/Pages/adam-sciegaj.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />More about Adam Sciegaj​​</a></div> <div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Adam Sciegaj​ on Linkedin</a><br /></div> <div><br /></div> <div><strong>Dissertation:</strong> March 6 2020, at 9.00 in <a href="/en/areas-of-advance/production/society-industry/laboratories/csilab/Pages/map-and-address.aspx">Virtual Development Laboratory VDL ​</a></div> <div><br /></div> ​Mon, 10 Feb 2020 00:00:00 +0100 Student Competition 2020 &quot;Hotel Chalmers - a new hotel at Chalmersplatsen<p><b>​​Ella Davidsson won the 1st Prize in the Melchior Wernstedt Student Competition 2020.</b></p><h2 class="chalmersElement-H2">​<span>​1st Prize  </span></h2> <div>Motto: BRIQUE</div> <div> </div> <div>Author: Ella Davidsson, Student MPARC Prize: 7001 SEK</div> <div> </div> <div><br /></div> <div> </div> <div><a href="/en/departments/ace/education/School-of-Architecture/Courses-and-projects/Wernstedt%20Sketch/Pages/2020.aspx">See the winning entries here &gt;&gt;</a></div> <div> </div>Fri, 07 Feb 2020 14:00:00 +0100 floodings in cities with green roofs<p><b>​The amount of rain and extreme rainfall is expected to increase on our northern latitudes because of climate change.

For example, it can contribute to generally reduced well-being, respiratory difficulties, heat cramps, fatigue and heat stroke”, says Gaetano Sardina, assistant professor in the Division of Fluid Dynamics at the Department of Mechanics and Maritime Sciences.<p></p> <p>In densely populated areas, temperatures become higher and the air quality deteriorates due to lower wind speeds as buildings act as a wind trap and shut in the hot and polluted air. This effect is known as &quot;Urban Heat Islands&quot; and is most noticeable during the summer and winter months. Also, the effects of heatwaves in the urban areas are heightened with increased air temperature. Sensitive individuals such as children, the elderly and people with certain illnesses are particularly exposed to such events.</p> <h2 class="chalmersElement-H2">Bad air increases deaths</h2> <p>The combination of severe heat and high levels of air pollution can be very problematic. The Centers for Disease Control and Prevention estimates that between 1979 and 2003, heat waves contributed to more than 8,000 premature deaths in the United States. It is more than the deaths caused by hurricanes, lightning, tornadoes, floods and earthquakes altogether.</p> <p>The large-scale effects on society are evident in the increase in costs for health care, lost working days and reduced productivity. But researchers expect that economic losses due to increased temperatures in urban areas can be reduced by up to 200 per cent in cities that have implemented appropriate measures.</p> <p>“Our goal is to find out how the cities of the future will be built to improve thermal comfort and air quality for its inhabitants.

The long-term goal is to enhance Egnahemsfabriken’s support structure to make it working well also for young people, so that youths are reached when the support structure in the long run is scaled up to other municipalities in the country.</span><div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">More information</span></div> <div><a href="/en/Staff/Pages/jenny-stenberg.aspx">Jenny Stenberg</a>, Associate Professor, Architecture and Civil Engineering, Architectural Theory and Methods</div>Thu, 31 Oct 2019 11:00:00 +0100's-William-Chalmers-lecturer-to-the-paradise-of-clay-–-Gothenburg.aspx's-William-Chalmers-lecturer-to-the-paradise-of-clay-%E2%80%93-Gothenburg.aspxFollow this year&#39;s William Chalmers lecturer to the paradise of clay<p><b>​Professor Minna Karstunen was already clinging to clay as a child - and it finally led her to Chalmers.

I ran away into a field and made bears out of mud. When I got home covered in dirt my mom got very angry and had to clean me with the garden hose…”</div> <div>The clay was rinsed from the clothes, but her interest in the material has lived on. After studying geotechnics, and almost 20 years in the UK –  first as a doctoral student in Swansea, Wales and then as academic in Glasgow, Scotland – it was once again the clay that guided her steps. This time to Chalmers.</div> <div>“For research on clay, Gothenburg is a paradise.

It is no problem to build it if you have good predictions and plans for what to do if you encounter foreseen and unforeseen problems”.</div> <div>Then, what is so special about the Gothenburg clay, this controversial soil that some claim is impossible to build through?</div> <div>“First of all, there is a lot of clay. It is soft and, in some places, it is also a possible natural hazard. This isn’t a material to play with, and we do not yet fully understand why it behaves the way it does”.</div> <div>“The Gothenburg clay is special – but not so special. In Mexico City there is a much softer clay and there they have been able to build a subway. Oslo, Helsinki and Saint Petersburg also have similar conditions as here.

Here, flesh implies thickness. It is explored in pliable casts and moulds made from silicone that engage the visitor and provoke a response. The exhibited interactive pieces, hybrid artefacts, graphic animations and tactile samples have been developed through the encounter between mechanical and human, precision and imprecision. What appears to be a highly predictable process in the digital realm, is in fact the result of fluid artistic investigation: architect and researcher <a href="/en/staff/Pages/malgorzata-zboinska.aspx">Malgorzata Zboinska</a> and her interdisciplinary team have extended the field of computational innovation by introducing imprecision, unpredictability, craft and co-creation with the machines into their research. </span><div><br /></div> <div>Hence, the artefacts on display arise from collaborative making and generate an alternative perspective on what contemporary digital architecture could become. Collectively, these works seek to embody a wider understanding of architectural flesh. They speculate on the kind of digitalized environments that could emerge in the future and push the realm of digital architecture by including artistic and corporeal conditions. In so doing, they invite us to reflect on the future dialogue between craftsmanship and digital design in a way that also embraces their relationship with nature. </div> <div><br /></div> <div><div></div></div> <h2 class="chalmersElement-H2">Special Events  </h2> <div><strong>Opening Vernissage 5 November 2019, 18:00-21:00</strong>, tours with Artist November 6.​<br /></div> <div>Date of Exhibition: 5-16 November, 2019</div> <div>Location: Färgfabriken, Lövholmsbrinken 1, 117 43 Stockholm (Metro: Liljeholmen, Tram: Trekanten).<br /></div> <div><br /></div> <div><div>Curated by: Anna Maria Orrù, <span style="background-color:initial">t</span><span style="background-color:initial">el</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial">: 0720 162 162</span><span style="background-color:initial">​, </span><span style="background-color:initial">e</span><span style="background-color:initial">mail: <a href=""></a>  </span></div> <div></div> <div><br /></div> <div><span></span><span></span><div>More information:</div> <div>Malgorzata Zboinska, phone: +46 31 772 65 27, email: <a href="">​</a>​​​</div></div></div> <div><br /></div> <div>The exhibition culminates from an artistic research project &quot;<a href="/en/projects/Pages/Architectural-Convertibles.aspx">Architectural Convertibles: Towards an alternative artistic approach to designing interactive architectural Environments​</a>&quot;, funded by the Swedish Research Council Vetenskapsrådet.<br /></div>Wed, 25 Sep 2019 16:00:00 +0200 and Economy united in new professorship<p><b>​Sweden&#39;s first interdisciplinary professorship in architecture and economy is being appointed at Chalmers University of Technology in Gothenburg. The Austrian architect Walter Unterrainer is the professor who will link architecture with knowledge in business, and thereby develop the role of the architect for generations to come.</b></p>– We are very pleased to announce that Walter Unterrainer will be assuming the post in September. Walter's solid experience, both theoretical and practical, provides an opportunity for quicker knowledge development in the vital connection between architecture and economy. This is an exciting component that we are adding to Chalmers' faculty, says Fredrik Nilsson, Head of Department of Architecture and Civil Engineering.     <br /><br />Born and raised in Austria, Walter Unterrainer has previously run his own architectural firm and has long-standing experience from the academic world. His work emphasises on environmental sustainability, and by building on his own behalf, he has developed a number of innovative solutions for energy efficiency as well as cost reduction. The move to Chalmers, where he has previously given lectures, goes from Aarhus School of Architecture in Denmark.     <br /><br />– I consider questions regarding economics as fundamental for architecture as well as for the architectural profession. Economy decides if and how an architectural idea can be turned into a concrete, material reality. In my opinion, economics in architecture consists of responsible management of all resources, which can refer to environmental assets, funds, a specific location, existing buildings, residue, and human resources. The discussion about the actual cost, and more importantly value, connects a pragmatic view on architecture with the bigger questions we face today regarding climate change, the depletion of natural resources, and social development, says Walter Unterrainer.    <br /><br />In Germany and many other European countries, academic posts that connect economics and architecture already exist. However, in Sweden, the professorship, which is financed by Maria and Magnus Månsson's Trust, will be the first of its kind.      <br /><br /><div>– As architects, we need to possess a greater knowledge of business if we want to add value to what we design. This is vital whether we are working with a private client, or establishing a zoning plan with the City Planning Office. This is why I'm excited Walter, a highly-skilled and internationally renowned colleague, is coming to Chalmers. We will now be incorporating the economic understanding as a segment of the education, and I look forward to seeing how it will affect and change the architectural role overtime, says Magnus Månsson, group president at Semrén &amp; Månsson, Adjunct Professor at Chalmers and founder of The Maria and Magnus Månsson Trust.<em></em><span><em></em></span><br /></div>Thu, 29 Aug 2019 08:00:00 +0200 in Digital Twins will revolutionise urban development<p><b>​With today’s technology that enables the creation of digital twins, a car or airplane can be modeled, simulated and optimized before it leaves the drafting table.  A progress that is about to become reality even for something as complex as whole cities. Swedish innovation agency Vinnova have recently announced a grand and long-term investment into a Chalmers based competence centre that will lead the development.</b></p>​Cities are the largest and most complex human artifacts, and also the most resource consuming and waste producing.  The share of the world’s population living in cities is increasing every year, which also increases the need for a transformation into sustainable design of our cities. The integration of digital methods can be of great support in this challenge. Like the process of designing an airplane or a car based on mathematical modeling, simulation and optimisation, cities could be designed to become more livable, efficient and resilient as they may be analysed and experienced before they are built. The undertaking from Vinnova makes the basis of a total investment of SEK 100 million to create opportunities to analyze and test the components of urban development in a completely new way.    <br /><br /> – We are extremely happy and proud. Behind our application is very hard and long-term work from a committed team at Chalmers in close collaboration with our partners, says Professsor <a href="/en/staff/Pages/logg.aspx">Anders Logg</a>,  Department of Mathematical Sciences and one of two designated directors of the centre. <br /><div><h3 class="chalmersElement-H3">Copies improves the original</h3></div> <div>Digital twins is a concept that have revolutionized the manufacturing industry and is used daily to construct increasingly refined products. The technology has spread to include the planning and development of our cities but is usually limited to visual representation. Digital Twin Cities will develop the concept of digital twins for cities by modeling and simulating the city as a complex multi-physics system based on real-time data.    </div> <br /> – Digital Twin may be a well-established concept, but what’s unique about our concept compared to those elsewhere, is that we aim to integrate what is underground, treating the city as a four-dimensional complex system in our simulations, says Professor <a href="/en/staff/Pages/minna-karstunen.aspx">Minna Karstunen</a>, Department of Architecture and Civil Engineering and designated director of the centre.    <br /><br />The uniqueness of the concept was something Vinnova noted in their assessment, expressed in their motivation as follows: ”The novel approach in an otherwise well addressed field was deemed impressive by the evaluators, combining open source, smart city developments and public sector linkages, convincing the evaluators of the potential of the application.”   <br /><div><br /></div> <div><h3 class="chalmersElement-H3">Gathers a diversity in competencies</h3></div>  – We now have the possibility to fulfill and scale up our pilot VirtualCity@Chalmers, which will make the cornerstone in the development of our centre. At the same time, we will now be able to take advantage of the strong competence already existing at Chalmers within modeling, simulation and visualization of cities, by combining our competencies in architecture, engineering, mathematics and computer science, with experience and current challenges from our partners, Anders Logg concludes.    <br /><br />A broad consortium of 28 Swedish and international stakeholders with the base in Chalmers will cooperate in Digital Twin Cities. Cutting-edge research will be conducted in eight different research areas, covering all aspects needed to develop the large-scale digital twin technology, and to harvest the opportunities it brings in new approaches to urban planning &amp; design, architecture and digital construction. To facilitate uptake and implementation for Sweden to spearhead the necessary digitalization of the built environment sector, a particular focus will be on knowledge transfer to industry and public actors.    <br /><br /> – It is a fantastic opportunity and very exciting.
