Car sharing has shown to reduce car ownership and reduce driving, and is expected to be part of the solution to achieve a more sustainable mobility system. Car sharing is a well-known concept, but up until today very few cars are shared and car sharing does not seem to compete with car ownership to any large extent. To be able to develop more attractive car sharing services that can compete with car ownership, knowledge of user motives for and against car sharing is needed. </div> <div><br /></div> <div>This study aimed to explore user motives for and against car sharing in comparison to car ownership. Further, it aimed to relate these motives to characteristics of the car sharing service to explore how car sharing services could be improved, from a user perspective, to better compete with car ownership. </div> <div><br /></div> <div>To do so an in-depth, exploratory interview study with current and former car sharing users in the city of Gothenburg was carried out. The interview study and subsequent analysis followed the methodology of Means-End Chain, which explains the user motivation in terms of car sharing attributes, the functional and psychosocial consequences that the user experience from using car sharing, and personal values that are assumed to explain why these consequences are desirable for the user. This gives a detailed understanding of user motives and how they are associated with car sharing characteristics. The results show that motivational patterns to use car sharing are 'Value-seeking', 'Fewer worries', 'Sustainability' and 'Access to modern cars'. Motivational patterns against car sharing are 'Fewer trips', 'Less flexibility, spontaneity and freedom' and 'Additional effort in the travel process'. </div> <div><br /></div> <div>These findings correlate well with motives found in previous research on car sharing and car ownership but gives a more in depth and nuanced picture of user motives. It can be seen that the same car sharing characteristics can both motivate and demotivate car sharing, depending on what the user values and what it is compared to. This emphasizes the importance of an in-depth understanding of user motives when developing more attractive car sharing services. The results can be useful for car sharing operators in developing services that fit the user needs, in designing further research studies on car sharing motives and city planning authorities that are interested in introducing car sharing services in their cities as a way to reduce car ownership.​</div> thesis presentation, Jan Jürgen Eisenmenger<p>Zoom</p><p>​Ground surface classification by stereo polarised image sensors</p><div><div><span style="background-color:initial">Jan Jürgen Eisenmenger presents his master’s thesis work “​Ground surface classification by stereo polarised image sensors”.</span><br /></div> <div><br /></div> <div>Supervisor: Ole Martin Christensen</div> <div>Examiner: Christian Berger​</div></div> <div><br /></div> ​<a href="" style="font-family:calibri, sans-serif;font-size:14.6667px">Presentation via Zoom​</a><span style="font-family:calibri, sans-serif;font-size:14.6667px">. </span> thesis presentation Carlos Cesar Canelada Martinez<p>Online</p><p>​Prosumers’ role in a changing electricity system: the non-individual prosumer perspective</p>​<span style="background-color:initial">Carlos Cesar and Canelada Martinez</span><span style="background-color:initial"> present their master’s thesis work “</span><span style="background-color:initial">​Prosumers’ role in a changing electricity system: the non-individual prosumer perspective</span><span style="background-color:initial">”, at the Department of Space, Earth and Environment.</span><div><span style="background-color:initial"><br /></span></div> <div>Supervisor: Sujeetha Selvakkumaran, Energy Technology</div> <div>Examiner: Erik Ahlgren, Energy Technology</div> <div>Opponent: Maria de Oliveira Loureiro</div> <div><br /></div> <div><span></span><a href="">Online presentation​</a>. ​</div> <div><br /></div> Lecture, Carl Johan Linderholm<p>Online</p><p>​​How carbon capture may yet save us from catastrophic climate change</p><img src="/SiteCollectionImages/Institutioner/SEE/Profilbilder/Carl_Linderholm_170.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Carl Johan L<span style="background-color:initial">inderholm, at the division Energy Technology, </span><span style="background-color:initial">Department of Space, Earth and Environment, </span><span style="background-color:initial">will hold his</span><span style="background-color:initial"> docent lecture (for ”oavlönad docent”) </span><span style="background-color:initial">entitled: ​How carbon capture may yet save us from catastrophic climate change</span><span style="background-color:initial">.</span><div><div><br /></div> <div><div>​Abstract:</div> <div>Climate change is upon us. Reducing emissions is no longer enough – the emissions need to be eliminated, and ultimately reversed. The challenges are enormous, but the good news is that they are manageable from a technological viewpoint. One of the possible solutions is spelled BECCS – Bio-Energy Carbon Capture and Storage. The first step of the BECCS concept is capturing the CO2, and in this presentation I will explain why chemical-looping combustion (CLC) is perhaps the most promising technology for CO2 capture.</div></div></div> <div><br /></div> <div><a href="">Presentation online​</a>. ​<br /></div> thesis presentation, Gustav Tellwe<p>Online</p><p>​A Bayesian machine learning approach to geostationary infrared precipitation retrievals</p>​<span style="background-color:initial">Gustav Tellwe</span><span style="background-color:initial"> presents his master’s thesis work “​A Bayesian machine learning approach to geostationary infrared precipitation retrievals</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial">”, at the Department of Space, Earth and Environment.</span><div><div><br /></div> <div>Supervisor: Patrick Eriksson</div> <div>Examiner: Simon Pfreundschuh​ </div> <div>Opponent: Selma Tabakovic</div></div> <div><br /></div> <div></div> <div><span></span><span></span><a href="">Presentation online</a>.​​</div> <div><br /></div> Fogasy, Space, Earth and Environment<p>Online</p><p>​High-redshift  active galactic nuclei and their environment</p>​<span style="background-color:initial">Judit Fogasy</span><span style="background-color:initial"> will defend her </span><span style="background-color:initial">thesis: &quot;​High-redshift active galactic nuclei and their environment</span><span style="background-color:initial">​</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial">&quot;. </span><div>Judit Fogasy​ is a PhD Student at the division of <span style="background-color:initial">Astronomy and Plasma Physics, </span><span style="background-color:initial">at the Department of Space, Earth and Environment.</span></div> <div><br /> </div> <div>Supervisor: Kirsten Kraiberg Knudsen, <span style="background-color:initial">Astronomy and Plasma Physics</span><span style="background-color:initial"> </span></div> <div></div> <div>Examiner: Hans Olofsson, <span></span><span style="background-color:initial">Astronomy and Plasma Physics​</span></div> <div>Faculty examiner: Alexandra Pope, associate professor, University of Massachusetts, Amherst</div> <div><br /> </div> <div><a href="">Read the thesis and find zoom link for online defense here</a>.</div> thesis presentation, Renesteban Forero Franco<p>Online</p><p>​Creating a digital clone of a Process Plant using Neural Networks​</p>​<span style="background-color:initial">Renesteban Forero Franco presents his master’s thesis work “​Creating a digital clone of a Process Plant using Neural Networks”, at the Department of Space, Earth and Environment.</span><div><br /></div> <div>Examiner: Fredrik Normann​, Energy Technology</div> <div>Opponent: Shravan Kumar and Pinayur Kannan </div> <div><br /></div> <div><span style="font-size:11pt;font-family:calibri, sans-serif"><a href="">Presentation Online</a>.</span><br /></div> Shavalieva, Space, Earth and Environment<p>Online</p><p>​Environmental, health and safety assessment of phase-change solvents for post combustion CO2 capture</p>​<span style="background-color:initial">Gulnara Shavalieva presents her licentiate thesis “Environmental, health and safety assessment of phase-change solvents for post combustion CO2 capture”.

In this project, alternative route generation and robustness analysis were conducted for common road networks and off-road terrains. This was done using Open Street Map data and high-resolution terrain data provided by Vricon. Alternative routes were generated using a constructed 2-way search algorithm. Robustness analysis was split into a physical robustness-index and a non-physical robustness simulation. The generated routes conform to the constructed robustness-index, which is sensitive to weather conditions when traversing terrain. The simulation is applied to the generated routes to visualize additional penalty times where the user can identify critical points along said route. This is done using a robustness simulation which creates obstacles along the chosen path and calculates the additional time needed. The final result is a complete Java program connected to Carmenta Engine, a map engine provided by Carmenta. The resulting program showed conceptually promising routes, providing reasonable alternatives while accounting for current weather conditions.</span><br /></div></div> <div><br /></div> Talks with Maja Rosén<p>Live stream via Zoom!</p><p>​​When COVID cut our wings</p><em>​</em><span style="background-color:initial"><em>​With planes on the ground and society homebound, what is the future of mobility?<br /><br /></em></span><div><div>In a matter of days, Coronavirus achieved what many climate activists and scientists have spent years striving towards; it brought aviation to a standstill across the globe. As flying flatlined and carbon emissions dropped in Sweden, an industry on the brink cut costs and requested bailouts. Despite the cautious optimism from within the climate community, there are also larger signs of uncertainty for the future of mobility; COVID-19 may have profound implications for not only flying, but also how we travel and move on a daily basis. What may this sudden moment of transformation mean for long-term transitions? Can practices developed or curbed during the pandemic lead to lasting societal norms? Is this simply a momentary lapse in the act of flying and the systems that support it? In this seminar we discuss the role of aviation in the climate transition and explore what may await aviation in a post-corona world.</div> <div><br /></div> <div><strong>Keynote</strong></div> <div>Maja Rosén, climate activist and the co-founder of the organisation <em>We Stay on the Ground</em>, and the campaign <em>Flight-Free 2020</em>.
