1. 1. N-body simulations of exoplanets and their moons

   Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Lydia Schollmeier; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. LÄS MER

3. 2. Supply Chain Resilience within the Automotive Industry - A single-case study on the importance of Supply Chain Resilience practices for an automotive MNC as a result of the COVID-19 pandemic and the Russia-Ukraine war

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Kawi Ali; Kevin Aslani; [2023-07-18]
   Nyckelord :Supply Chain Resilience; Supply Chain Management; automotive industry; COVID-19; Russia-Ukraine war; Volvo Cars–Polestar; disruptions; strategies;

   Sammanfattning : Background: The automotive industry is a complex industry and sensitive to the business environment surrounding it. This has been shown by the last years, which have been dominated by disruptions and economic turbulence due to the COVID-19 pandemic and the war between Russia and Ukraine. LÄS MER

4. 3. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Svante Rosenlind; [2023]
   Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

   Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER

5. 4. Exploring the Issues with ESG assessments in Investment Decision-Making : Insights from the Swedish Fund Market

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Victoria Engström Kindmark; Ellen Surtevall; [2023]
   Nyckelord :ESG assessment; ESG rating; issues; challenges; sustainable investing; investment decision; mutual funds; ESG-bedömning; ESG betyg; utmaningar; svårigheter; hållbara investeringar; investeringsbeslut; fonder;

   Sammanfattning : Sustainable investing has seen a significant increase in the past years and is continuing to gain momentum with the constant rise of awareness and concern of the climate crisis. It is necessary for modern mutual fund companies to conduct ESG assessments as it provides a comprehensive understanding of a firm's sustainability performance, and identifies potential risks and opportunities which lay ground for investment decisions.

7. 5. Discover patterns within train log data using unsupervised learning and network analysis

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Zehua Guo; [2022]
   Nyckelord :Log analysis; Natural language processing; Unsupervised learning; Clustering; Network analysis; Logganalys; Bearbetning av naturligt språk; Oövervakat lärande; Clustering; Nätverksanalys;

   Sammanfattning : With the development of information technology in recent years, log analysis has gradually become a hot research topic. However, manual log analysis requires specialized knowledge and is a time-consuming task. Therefore, more and more researchers are searching for ways to automate log analysis. LÄS MER
