  2. 1. Towards Measurable and Tunable Security

    Author : Reine Lundin; Simone Fischer-Hubner; Stefan Lindskog; Viiveke Fåk; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tunable security; security measures; metrics; entropy; guesswork; privacy; anonymity; selective encryption; Computer science; Datavetenskap; Datavetenskap; Computer Science;

    Abstract : Many security services today only provides one security configuration at run-time, and cannot then utilize the trade-off between performance and security. In order to make use of this trade-off, tunable security services providing several security configurations that can be selected at run-time are needed. READ MORE

  4. 2. Theoretical studies of protein-ligand binding

    Author : Majda Misini Ignjatovic; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein-ligand binding; MD; GIST; GCMC; FEP; Solvation; Entropy; Water; QM MM-FEP; Protein-ligand binding; MD; GIST; GCMC; FEP; Solvation; Entropy; Water; QM MM-FEP;

    Abstract : Understanding how drugs work is of great importance, since it can facilitate drug discovery, both time- and costwise. At the same time, it is important to have methods that can help predict how well does a potential drug molecule bind to its target. Computational methods can in many ways contribute to drug design process. READ MORE

  5. 3. On Bayesian graphical model determination

    Author : Jukka Corander; Carlo Berzuini; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian inference; Entropy; Exponential models; Graphical models; Logarithmic utility; Statistics; Statistik; statistik; Statistics;

    Abstract : A graphical model specifies a graph representation of the independence structure of a multivariate distribution, where nodes represent variables and edges association between variables.This thesis introduces methodology for determination of graphical models for multivariate distributions within the exponential family.

  6. 4. Quantum-Mechanical Modeling of High-Entropy Alloys

    Author : Shuo Huang; Levente Vitos; Yang Wang; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : High-entropy alloys (HEAs) consisting of multi-principal elements open up a near-infinite compositional space for materials design. Extensive attention has been put on HEAs, and interesting structural, physical and chemical properties are being continuously revealed. READ MORE

  7. 5. Development and Application of Software Tools for Mass Spectrometry Imaging

    Author : Patrik Källback; Per E. Andrén; Per Svenningsson; Anna Nilsson; Benjamin Bowen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mass spectrometry imaging; MALDI; DESI; msIQuant; quantitation; neurotransmitters; drugs; derivatization; brain; compression; data entropy reduction;

    Abstract : Mass spectrometry imaging (MSI) has been extensively used to produce qualitative maps of distributions of proteins, peptides, lipids, neurotransmitters, small molecule pharmaceuticals and their metabolites directly in biological tissue sections. Moreover, during the last 10 years, there has been growing demand to quantify target compounds in tissue sections of various organs. READ MORE
