1. 6. Spinning Gold: Unraveling the Secrets of Value Creation from Spin-offs

   University essay from Handelshögskolan i Stockholm/Institutionen för marknadsföring och strategi

   Author : Andreas Groth; Fabian Bevanda; [2023]
   Keywords : Spin-Offs; Corporate Focus Hypothesis; Optimal Leverage Hypothesis;

   Abstract : This thesis explores the dynamics of value creation in American corporate spin-offs between 1995-2019 from the dual perspectives of the corporate focus and optimal leverage hypotheses. The research employs a comprehensive dataset of 164 cases, examining the impacts of spin-offs on long-term abnormal stock returns and both unadjusted and industry-adjusted operating performance.

3. 7. Wet spinning of carbon fiber precursors from cellulose-lignin blends in a cold NaOH(aq) solvent system

   University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

   Author : Landmér Alice; [2022]
   Keywords : Carbon fiber; cellulose; cold NaOH aq ; lignin; precursor; sodium hydroxide; solution spinning; wet spinning;

   Abstract : Carbon fiber (CF) is predominantly produced from fossil-based sources and is therefore an area of interest for further development towards a more sustainable society. The purpose of this thesis work was to investigate the possibility of producing precursor fibers (PFs) for CF production from a blend of renewable cellulose andlignin. READ MORE

4. 8. Laser Scattering for Fast Characterization of Cellulose Filaments

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
   Keywords : Cellulose nanofibrils; Fibers; Sustainable development; Bio-based material; Characterization; Microscale; Microscopy; Small-angle light scattering; Laser diffraction; Cellulosananofibriller; Fiber; H˚allbar utveckling; Biobaserade material; Karakterisering; Mikroskala; Mikroskopi; Ljusspridning; Laserdiffraktion;

   Abstract : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.

5. 9. Modeling and Control of a PMSM Operating in Low Speeds

   University essay from Linköpings universitet/Fordonssystem

   Author : Robin Helsing; Tobias Sanchez; [2022]
   Keywords : PMSM; BLDC; low speed; EKF; UKF; MPC; Extended Kalman Filter; Unscented Kalman Filter; PI; Control; FOC;

   Abstract : A permanent magnet synchronous motor is a type of motor that is used in several different application areas, not least in an autonomous robots where it is the motor that drives the wheels. Today, many actors choose simulation as a tool to save money and time when product tests are performed. READ MORE

6. 10. Spinning a Budding Industry

   University essay from Lunds universitet/Internationella miljöinstitutet
