  1. 1. Multiscale simulations of soft matter: systematic structure-based coarse-graining approach

    Author : Alexander Mirzoev; Alexander Lyubartsev; Nico van der Vegt; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Multiscale modeling; Monte Carlo; Molecular dynamics; ion solution; lipid bilayer; coarse-graining; fysikalisk kemi; Physical Chemistry;

    Abstract : The soft matter field considers a wide class of objects such as liquids, polymers, gels, colloids, liquid crystals and biological macromolecules, which have complex internal structure and conformational flexibility leading to phenomena and properties having multiple spacial and time scales. Existing computer simulation methods are able to cover these scales, but with different resolutions, and ability to link them together performing a multiscale simulation is highly desirable.

  2. 2. Precision measurement instruments for machinery's mechanical compliance: design and operation : Measurement instruments for physics-based calibration of advanced manufacturing machinery

    Author : Nikolas Alexander Theissen; Andreas Archenti; Alexander Slocum; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement instruments; Machine tools; Industrial robots; Production Engineering; Industriell produktion;

    Abstract :  Precision Measurement Instruments (PMIs) for machinery’s mechanical compliance are tools to quantify mechanical load as well as length for measurement ranges of 0.1 µm to 10 m at uncertainty levels of 0.1 µm to 100 µm while exerting mechanical loads. READ MORE

  3. 3. High-Performance Computing For Support Vector Machines

    Author : Shirin Tavara; Alexander Schliep; Alexander Karlsson; Richard Johansson; Högskolan i Skövde; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Skövde Artificial Intelligence Lab SAIL ; Skövde Artificial Intelligence Lab SAIL ; INF301 Data Science; INF301 Data Science;

    Abstract : Machine learning algorithms are very successful in solving classification and regression problems, however the immense amount of data created by digitalization slows down the training and predicting processes, if solvable at all. High-Performance Computing(HPC) and particularly parallel computing are promising tools for improving the performance of machine learning algorithms in terms of time. READ MORE

  4. 4. Target and Laser Pulse Optimization for Laser-Driven Ion Acceleration

    Author : Alexander Permogorov; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Terawatt laser; Target normal sheath acceleration; laser-driven ion acceleration; proton acceleration; double plasma mirror; Thomson parabola spectrometer; Fysicumarkivet A:2021:Permogorov;

    Abstract : The research presented in this thesis is primarily focused on experimental investigations of laser-driven ion acceleration from solid targets via the target normal sheath acceleration mechanism. In particular, ways of optimizing the absorption of the laser pulse energy by free plasma electrons in the target, or modifying the shape of the accelerating electron sheath were addressed.

  5. 5. Modeling and Mechanistic Investigation of α-synuclein aggregation

    Author : Alexander Svanbergsson; Neural plasticitet och reparation; []

    Abstract : Our understanding of the α-synuclein aggregation process and the consequences thereof is currently limited, which in turn prevents the development of targeted therapeutic interventions. The work presented here, as a part of this thesis, is focused on expanding our understanding of the molecular events involved in α-synuclein aggregation. READ MORE
