Tracks är ett utbildningskoncept som utvecklar både lärandet och lärandemiljöerna på Chalmers. Tracks betyder spår och det är just det Chalmers studenter erbjuds – spår mellan olika utbildningar i form av valbara kurser, där valen styrs av eget intresse. Inom ramen för Tracks finns möjligheter till individualiserad studiegång och samverkan mellan näringsliv, samhälle och akademin.
Tracks is a unique educational initiative regarding learning and learning environments that prepares the university for the needs of tomorrow.
Tracks are exactly what Chalmers students are offered – tracks between different programmes in the form of elective courses, where the choices are guided by personal interest. The framework of Tracks provides opportunities for individualised study and collaboration between students, industry, the community and academia.

- PostA sustainable marine transport sector(2021) Alvelid, Carl; Schmidt, Daniel; Ljunge, Jonna; Gutke, Julia; Pai, Rahul Rajendra; Muthukrishnan, Shruthik Krishnan; Chalmers tekniska högskola; Sjöblom, Jonas; Sjöblom, JonasIn today’s highly globalised world, marine transport accounts for an important mode of travel as well as a key means of enabling transcontinental trade. There is an urgent need for a shift towards a more sustainable marine sector as the demand for at sea transport and shipping increases annually with rising levels of harmful emissions as a result. Moreover, the future of the fossil fuels currently employed for marine vessel propulsion is most unclear. The widely used Heavy Fuel Oil might become subject to highly volatile pricing as the global market moves towards reducing its fossil dependence. Also, stricter emission norms intended to bring the marine transport sector closer to the legislative levels already developed in land-based transportation are to be expected. This report introduces and discusses a selection of emissions-reducing measures which could contribute to a more sustainable marine transport sector, namely, biofuels, solar panels and electrification, hydrogen, fuel cells, methanol, speed reductions and wind power. Ultimately, wind power is chosen as a final suggestion with respect to lowering marine emissions. Wind is a free, renewable, and abundant form of energy especially suitable for marine transport and its extraction for marine vessel propulsion does not induce resource scarcity in other sectors. Biofuels are more expensive than the current fuels in use and pose environmental and ethical dilemmas related to land use change with the potential of creating distributional conflicts. When compared to other options, fully wind powered ships have the unparalleled benefit of zero emissions in theory. In contrast to solar power, wind power alone is sufficient for vessel propulsion although there is need for alternative methods if the wind direction and magnitude does not meet the requirements. Electric vessels struggle with low energy density in batteries and a complete lack of charging infrastructure, only permitting shorter voyages inadequate for meeting the demand for worldwide transport. Hydrogen fuels cause a considerable loss of usable shipping volume, and thus profit, due to its low volumetric density. Finally, from a stakeholder perspective it is argued that although initial investments may be high due to re-equipping or replacing of ships, wind power is a viable economic solution long-term as the “fuel” is inherently abundant and free. Also, a zero-emissions option like wind power is likely to be favourable in the eyes of authorities which are able to introduce policy instruments supporting the transition to a wind-powered marine future.
- PostAutomating Qubit Tune-up and Mixer Calibration(2021) Abram, Hari; Jirlow, Martin; Heuts, Olivia; Chalmers tekniska högskola; Geresdi, Attila; Eriksson, Axel; Castillo Moreno, ClaudiaIn this project we write scripts to automate qubit tune-up and mixer calibration, with the aid of the Labber instrument software and the Labber Python API. The python scripts are written to perform the measurements on two microwave platforms, Vivace and Keysight. The scripts then process the data from the measurements to extract the desired measures for qubit tuneup and mixer calibration. To conclude we note that although the scripts are able to perform there is still much room for improvement.

- PostQuantum Limited Amplifier: Design, Fabrication and Characterization of a Superconducting NbTiN Kinetic Inductance Travelling Wave Parametric Amplifier(2021) Alcalde-Herraiz, Núria; Andersson, Linus; Hagström, Ivan; Jamet Suria, Paul; Chalmers tekniska högskola; Geresdi, Attila; Geresdi, Attila; Gasparinetti, SimoneThe aim of this project was to design, fabricate and characterize a kinetic inductance travelling wave parametric amplifier (KI-TWPA) for cryogenic temperatures (10 mk) by adapting the design of Malnou et.al PRX Quantum (2020) [1] for a sapphire substrate of 430 μm. By utilizing the properties of periodic structures in a transmission line, the dispersive properties of the device could be modified, enabling phase matching of the signal and pump frequencies. The pattern was designed on Klayout, simulated in Sonnet[2] and fabricated in Chalmers MC2 cleanroom by sputtering of NbTiN, Electron beam lithography and Reactive ion etching. Additionally, a cryogenic microwave packaging was designed and fabricated. The packaging consists of a PCB designed in KiCad and a copper box designed in Autodesk Inventor. The PCB consists of two copper layers with Rogers RO4350B dielectric material in between the layers. The transmission line showed good matching in the frequency region of importance. When designing the copper box, the dominant cavity and chip resonant frequencies were engineered to exist outside the band of operation. The microwave properties of the PCB and copper box were simulated using COMSOL[3]. The superconductive device was measured at cryogenic temperatures and important device parameters were characterised. In particular, the kinetic inductance of the sample was characterised as well as the critical current of the device. The order of non-linearity was found to be I∗ = 7.33 - 8.26 mA and the critical current Ic = 2.2 mA. Through measurements of the transmission, the passband and stopband characteristics of the periodic structure were obtained. Thus, acquiring key parameters for the device. Due to fabrication issues, only one of the samples with a shorter amplification path could be measured. Therefore, signal gain could not be observed on the measured device since the gain is heavily dependant on the length of the transmission line.
- PostCompiling Quantum Conditionals in a Functional Language(2021) Botö, Nicklas; Forslund, Fabian; Chalmers tekniska högskola; Geresdi, Attila; Geresdi, AttilaWe present the functional quantum programming language Signe. The language features type inference, quantum conditionals, and compiles to multiple low-level representations. A compiler for Signe is presented with an implementation in Haskell. The compiler uses a Hindley-Milner type system, linearity checking, compilation to circuit and matrix data types, and a modern, user-friendly syntax in the functional style. The operational semantics are described in terms of the category of finite quantum computations FQC. Signe’s semantics and the FQC category are based on the QML language by Altenkirch and Grattage [1, 5, 4].

- PostEstablishing a Primary Healthcare Center for Students in Gothenburg: An investigation of the needs, possibilities and designs of a primary healthcare center for university students(2022) Steffner, Alva; von Sydow, Anna; Trinh, Thomas; Chalmers tekniska högskola; Hellström, Andreas; Alexandersson, PatrikAttending university is for most students a challenging period in life, often in combination with being a young adult and experiencing new mental and physical situations. Having access to support within healthcare and student health service is important to maintain a healthy life as a student. This report aims to investigate the healthcare needs and current healthcare services for university students in Gothenburg. Furthermore, this report aims to investigate the possibilities and propose solutions and design ideas for opening a primary healthcare center owned by Gothenburg’s Students Company Group and targeted at university students of Gothenburg. The suggestions are also based on investigating the healthcare needs and current services of university students in Gothenburg. This study is a literature review as well as an interview study with key persons and companies. The results show that there seems to be an increased prevalence of mental illness among young adults, where university students may be particularly susceptible to mental health issues, which indicates a need for more preventative care and adjusted healthcare. The suggested solutions for a primary healthcare center for students include adjustments in the organizational design and a location close to the students. The conclusion is that there is a need for more preventive care and adjusted healthcare for students, and by utilising all possibilities when opening a primary healthcare center for students, it has the potential to not only help students in need of healthcare but also make the students of Gothenburg healthier.

- PostIncorporation of phase changing materials (PCMs) with solar cells(2022) Smita, Smita; Mandeya, Andrew; Levin, Erik; Lizzmatz van de Laak, Marion; Chalmers tekniska högskola; Albinsson, Bo; Albinsson, BoThe increased use and scale of solar Photo-voltaic (PV) systems area increasing in the world and so are the global temperatures. As PV cells are heated, the cells lose efficiency due to a decrease in energy bandgap. Passive cooling using PCMs may counteract this effect and improve the PVs electrical power output. This report aims to investigate PV-PCM systems by performing an experimental labotary set-up and by reviewing existing theoretical models. The conducted experiment could not with any scientific certainty identify a difference although a 3.6 % increase using PCM would be observed in some instances. The theoretical model, using a day in Gothenburg with a simplified heat flux model, resulted in a 5.3 % increase in total power production during the day. While no part holds any real scientific value on its own, the results do indicate to some degree that a PV-PCM system can improve the output and further experiment and researched should be conducted to determine these effect. Finally, the report aims to reflect on the potential impact that PCMs have on the environment and the existing challenges that prevent the technology from reaching commercial scalability.
