Research has been mostly conducted either on specific sectors, or specific resources. A research field that deals withthese questions is called Urban Metabolism, and the few studies made provide coarse and aggregated description of resource use in cities, indicating the need for further advancements in scientific knowledge. In this opening lecture, a research proposition for Urban Metabolism is going to be presented, showcasing the work done byt he Urban Metabolism group at Chalmers in the past five years and how it contributes to unlocking knowledge to study cities in detail, and how this is useful for society. Emphasis will be put on the need to develop better analytical tools and models, that are,<br />to the extent possible, universal in their nature. defence in mathematics: Christoffer Standar<p>Pascal, Hörsalsvägen 1</p><p>On finite element schemes for Vlasov-Maxwell system and Schrödinger equation</p>​<br />Faculty opponent: Professor Francis Filbet, Université Toulouse III &amp; Institut Universitaire de France Nilsson<p>SB-H4, lecture hall, Arkitektur, Campus Johanneberg</p><p>​Laser Welded Steel Sandwich Panels for Bridge Applications</p><span><div><br />Abstract:</div> <div>The design of steel bridge decks has remained unchanged since the introduction of orthotropic decks. Orthotropic decks are expensive to produce, mainly due to high labor-costs. Furthermore, several joints (within the deck and between the deck and the surrounding structure) are highly fatigue sensitive, and the deck has a low stiffness in the transverse direction (i.e. perpendicular to the longitudinal stiffeners). This has in many cases led to premature deterioration and high maintenance costs. This thesis has a focus on laser-welded corrugated core steel sandwich bridge decks that have an increased stiffness-to-weight ratio and a more industrialized production with less complex detailing compared to conventional orthotropic steel decks. These enhancements lead to a more attractive solution with respect to economic and environmental sustainability. </div> <div> </div> <div>Structural analysis of a three-dimensional corrugated core sandwich panel using numerical methods is computationally heavy. In particular, the structural behavior of such panel in the transverse direction is rather complex. For that reason, this thesis is aimed at developing methods for simplified analysis incorporating homogenized beam and plate theories. Focus is put on predicting the stiffness and load effects in the direction transverse to the corrugation. A second aim of this thesis is to investigate the impact of variation of the production-dependent geometric parameters of the core-to-face joints of corrugated core steel sandwich panels on fatigue-relevant stresses in the vicinity of the laser stake welds. </div> <div> </div> <div>In order to utilize a simplified approach for static analysis of a corrugated core steel sandwich panel, a new analytical formulation for the transverse shear stiffness in the weak direction of the panel is presented in this thesis. To ensure that this stiffness property yields accurate predictions, the rotational rigidity of the weld region is simulated by a rotational spring. The magnitude of this spring is determined by a closed-form solution based on numerical and regression analyses. Both the transverse shear stiffness and the rotational spring is verified by numerical analyses and experiments. Furthermore, the impact of the variation of the production-dependent parameters is studied in this thesis by an extensive parametric study incorporating two-dimensional continuum numerical models. Numerical results are presented and discussed in detail. As an example, the parametric study shows that a misalignment between the weld-line and core direction can lead to a large increase of the fatigue-relevant stresses. </div> <div> </div> <h6 class="chalmersElement-H6">Keywords: laser-welding, sandwich panel, shear stiffness, corrugated core, joint geometry </h6><div> </div> <div><span> </span> </div> <div>Examiner and Main Supervisor : Mohammad Al-Emrani, Structural Engineering, ACE, Chalmers<br />Discussion leader: Sören Ehlers, TU Hamburg<br /></div></span><div><span> <span class="text-normal"> </span></span><span><span class="text-normal ingress"><span></span> </span></span></div> lecture, professorship in Mathematical Statistics: Petter Mostad<p>Pascal, Hörsalsvägen 1</p><p>​On forensic age estimation of asylum seekers and on replacing mathematical statistics with probabilistic data science</p><p>​<br />Abstract: <br />The process currently in use in Sweden for determining the age of asylum seekers has been hotly debated and criticized. I will go through the statistical features of the process, discussing estimation of error rates, but also how better and more optimal procedures can be constructed. </p> <p>In fact, current practices are far from optimal, and are but one example of how probability theory is <br />not used as well as it could be for making probabilistically based decisions in science and in society in general, even in mathematically simple contexts like age determination. I will argue that a root cause <br />of this deficiency is how mathematical statistics has been formulated and taught for generations, and will argue for radical changes. </p> <p>I will end with giving an overview of some of my other research activities and interests, such as exact inference in graphical networks and forensic statistics for both DNA and other types of observations. </p> Almquist, Systems and Synthetic Biology<p>KE, lecture hall, Kemi, Campus Johanneberg</p><p>​“Kinetic models in life science – contributions to methods and applications”</p>​<br /><strong>Opponent</strong>: Prof. Matthias Reuss, Stuttgart Research Center Systems Biology, University of Stuttgart<br /><br /><strong>Supervisor</strong>: Associate Prof. Mats Jirstrand<br /><strong>Examiner</strong>: Prof. Jens Nielsen, Chalmers<br /> Sun<p>SB-H3, lecture hall, Sven Hultins gata 6</p><p>​Contribution of stormwater ponds to aquatic biodiversity</p>​<br />Examiner: Professor Ann-Margret Hvitt Strömvall, ACE, Chalmers<br />Supervisor: Professor Sebastien Rauch, ACE, Chalmers<br />Discussion leader: Professor Thrond Oddvar Haugen, Norwegian University of Life Sciences seminar: Transitions in Practice - Lessons from the Energy Futures Lab in Canada<p>Analysen, meeting room, EDIT trappa D, E och F, EDIT</p><p>​​​It is time for the final CIIST-seminar for this year.

Steve will discuss the implications of the lessons learned - and the surprises along the way - for the design of participatory processes aimed at facilitating systems transition and ways of approaching energy systems transition.<br /><br />Registration is not mandatory but appreciated.<br /><strong>Contact:</strong> Hans Hellsmark, <a href=""></a> Moona<p>SB-M022, Sven Hultins gata 6</p><p>​​Modification of Granular Activated Carbon Filter used in Drinking Water Treatment</p><div>​</div> <div>Abstract:</div> <div>Drinking water is widely collected from surface water sources. In these water sources, both the quantity and quality of natural organic matter (NOM) have been affected around the world during the last decades, especially in Northern Europe and North America. This increasing NOM and its composition change challenge the drinking water treatment plants (DWTPs) due to e.g. increased coagulant demand, and because NOMs constituents act as precursors for potentially harmful disinfection by-products. Many DWTPs employing conventional treatment are currently struggling to maintain sufficient NOM removal, and are facing significant investments to upgrade existing treatment processes. </div> <div> </div> <div>In this thesis, a modification strategy to improve NOM removal by existing biological activated carbon (BAC) filters was tested. Analytical techniques like dissolved organic carbon, spectroscopic methods (absorbance and fluorescence) were used to monitor the performance of the modified filters in comparison to reference filters. In the second phase of the study, the modification strategy was employed in a different DWTP with different source water and coagulation treatment in order to validate the effectiveness of the proposed strategy under diverse conditions. </div> <div> </div> <div>Results show that replenishment of about 10% activated carbon media with new carbon media in BAC filters resulted in improved performance. The modified biofilters showed improved organic matter removal lasting for 10-20 days, depending on surface loading. In addition to improving the adsorption of humic-like NOM fractions, biological removal by the saturated filter media was enhanced. A subsequent validation study showed that improvement of biodegradation and adsorption mechanisms occurred in different DWTPs regardless of differences in NOM composition and coagulation processes prior to the BAC filters.</div> <div> </div> <h6 class="chalmersElement-H6">Keywords: Biofiltration, Drinking water treatment, Fluorescence, Granular activated carbon filter, Natural organic matter, Online monitoring, Spectroscopic properties <span></span></h6>,-Electrical-Engineering.aspx,-Electrical-Engineering.aspxSrikar L.

This challenge can be solved by increasing the transmission capacity through AC and DC solutions, and/or by introducing more energy storage in the grids to balance the fluctuations in wind and solar energy. All these applications require high-voltage, high-power electronic converters to connect generation and storage to the grid, or to compensate active and reactive power fluctuations. <br />This lecture will give an overview of the historical development of power electronics in grid-connected applications, including FACTS and HVDC transmission. Further, the current state of the art and topics for future research will be discussed. <br /><br /><strong>Short biography:<img src="/SiteCollectionImages/Institutioner/E2/Kalendarium/Jan_Svensson_150px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></strong><br />Jan Svensson received the Ph.D. degree from Chalmers University of Technology, Göteborg, Sweden, in 1998.

We live in dark times – climate crisis, economic regression, war and conflicts of political, ethnical and religious reasons. What used to be unrecognized by traditional planning debates can be useful to respond to contemporary planning problems. In-between spaces, insurgencies and untold stories can be rethought and re-explored to energize planning debates and practice. The challenges should be considered as triggers for transformations to a sustainable future.
