2. 1. Kinetic and Thermodynamic Modeling of Nanowire Growth

   Author : Erik Mårtensson; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nanowire; GaAs; InAs; Monte Carlo; Kinetics; Thermodynamics; III-V; Simulation; Fysicumarkivet A:2021:Mårtensson;

   Abstract : This thesis aims to expand on the fundamental knowledge of crystal growth, selectively focusing on the area of particle-seeded nanowire growth in the III-V materials system. The growth process is complex. READ MORE

4. 2. Some Notes on Post-Quantum Cryptanalysis

   Author : Erik Mårtensson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cryptography; Post-quantum cryptography; LWE; BKW; Cryptanalysis; Lattice sieving; SVP; Lattice-based cryptography; Code-based cryptography;

   Abstract : Cryptography as it is used today relies on a foundational level on the assumptionthat either the Integer Factoring Problem (IFP) or the DiscreteLogarithm Problem (DLP) is computationally intractable. In the 1990s PeterShor developed a quantum algorithm that solves both problems in polynomialtime. READ MORE

5. 3. Catalysts for Oxygen Production and Utilization : Closing the Oxygen Cycle: From Biomimetic Oxidation to Artificial Photosynthesis

   Author : Erik Karlsson; Jan-Erling Bäckvall; Björn Åkermark; Jerker Mårtensson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxygen; catalytic oxidation; biomimetic oxidation; artificial photosynthesis; water oxidation; DFT calculations; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Abstract : This thesis describes the development and study of catalysts for redox reactions, which either utilize oxygen or hydrogen peroxide for the purpose of selectively oxidizing organic substrates, or produce oxygen as the necessary byproduct in the production of hydrogen by artificial photosynthesis.The first chapter gives a general introduction about the use of environmentally friendly oxidants in the field of organic synthesis, and about the field of artificial photosynthesis.

6. 4. Organisational Adoption of Innovations : Management Practices and IT

   Author : Erik Lundmark; Alf Westelius; Nils-Göran Olve; Pär Mårtensson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Innovation; adoption; Non Profit Organisations; NPO; SME; ISO 9000; information technology; IT; ICT; communication; Technology Acceptance Model; TAM; Sport; Information technology; Informationsteknik; Economic Information Systems; Ekonomiska informationssystem;

   Abstract : This thesis describes effects of use and reasons for using three different organisational innovations: ISO 9000, Information and Communication Technologies (ICT) and an administrative tool (the YAF-module) in the Swedish Sports Confederation’s system Swedish Sports Online. This is done through three separate studies. READ MORE

7. 5. Decentralized Optimal Control for Multiple Autonomous Vehicles in Traffic Scenarios

   Author : Fatemeh Mohseni; Erik Frisk; Björn Olofsson; Jonas Mårtensson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : New transport technologies have the potential to create more efficient modes of transport and transforming cities for the better by improving urban productivity and increasing efficiency of its transport system to move consumers, labor, and freight. Traffic accidents, energy consumption, pollution, congestion, and long commuting times are main concerns and new transport technologies with autonomous vehicles have the potential to be part of the solution to these important challenges.
