1. 16. From Multiple Scale Modeling to Multiscale-Modeling

   Författare :Fabian Årén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-scale modeling; AIMD; DFT; MD; lithium-ion batteries; electrolytes; machine learning;

   Sammanfattning : To power a sustainable future, interest in battery research and technology is at an all time high. In order to enable a transition to green tech many applications, such as the automotive industry, is in need of higher power densities, energy densities, longer life-times, and safer batteries.

3. 17. Perspectives on the role of digital tools in students' open-ended physics inquiry

   Författare :Elias Euler; Bor Gregorcic; Cedric Linder; Konrad Schönborn; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; digital learning environments; modeling; semi-formalisms; microworlds; social semiotics; embodied cognition; disciplinary-relevant aspects; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

   Sammanfattning : In this licentiate thesis, I present detailed case studies of students as they make use of simulated digital learning environments to engage with physics phenomena. In doing so, I reveal the moment-to-moment minutiae of physics students’ open-ended inquiry in the presence of two digital tools, namely the sandbox software Algodoo and the PhET simulation My Solar System (both running on an interactive whiteboard).

4. 18. Atomistic modeling of materials under extreme pressure

   Författare :Tymofiy Lukinov; Anatoly Belonoshko; Levente Vitos; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

   Sammanfattning : This thesis is dealing with simulation of polycrystalline materials underthe conditions of anisotropic pressure and temperature. Work has been carriedout in three steps:ˆ Research of the inuence of point defects and grain boundaries on theprocess of melting. LÄS MER

5. 19. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling

   Författare :Ramin Ghorbani; Florian M. Schmidt; Anders Blomberg; Christoffer Boman; Staffan Schedin; Jonathan Beauchamp; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon monoxide CO ; pulmonary gas exchange; computational modeling; real-time breath gas analysis; single-exhalation profile; laser absorption spectroscopy; nonlinear least-squares fitting; breath sampling; baseline level; diurnal variation; healthy population; exposure study; fysik; Physics; Physiology; fysiologi;

   Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

7. 20. Modeling Oil Exploration and Production : Resource-Constrained and Agent-Based Approaches

   Författare :Kristofer Jakobsson; Kjell Aleklett; Rob Hart; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oil production; forecasting; modeling; Engineering physics; Teknisk fysik; Engineering Science with specialization in the Science of Global Energy Resources; Teknisk fysik med inriktning mot globala energiresurser;

   Sammanfattning : Energy is essential to the functioning of society, and oil is the single largest commercial energy source. Some analysts have concluded that the peak in oil production is soon about to happen on the global scale, while others disagree. LÄS MER
