  3. 2. Conformationally Constrained Nucleosides : Design, Synthesis, and Biochemical Evaluation of Modified Antisense Oligonucleotides

    Författare :Oommen P. Varghese; Lars Engman; Jacek Stawinski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; chemically modified oligonucleotides; azetidine; aza-ENA-T; cyanomethylene locked; free energy of activation; diaxial interactions; chair conformation; stable duplex; human serum; snake venom phosphodiesterase; antisense agents; RNase H; Organisk kemi; Chemistry; Kemi;

    Sammanfattning : This thesis is concerned with synthesis, structure and biochemical analysis of chemically modified oligonucleotides with potential therapeutic applications. The three types of chemical modifications described here are: (a) A North-East locked 1',2'-azetidine nucleoside (b) A North locked 2',4'-cyanomethylene bridged nucleoside and (c) A 2',4'-aza-ENA-T nucleoside.

  4. 3. Crystallization in Constrained Polymer Structures : Approaching the Unsolved Problems in Polymer Crystallization

    Författare :Eugenia Núñez; Ulf W. Gedde; Bernard Lotz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crystallization; Constrained structures; poly ε–caprolactone ; poly ethylene oxybenzoate .; Polymer chemistry; Polymerkemi;

    Sammanfattning : The knowledge regarding certain issues in polymer crystallization e.g. the possible existence of short–lived mesophases remains inconclusive due to experimental limitations. Polymers undergo chain folding upon crystallization, which introduces some complications that are not found in crystallization of low molar mass materials. LÄS MER

  5. 4. Methods for Constrained Optimisation of Propellers

    Författare :Florian Vesting; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cavitation; constrained optimisation; genetic algorithm; propeller geometry; response surface methodology; propeller hull interaction; Kriging; artificial neural network; RANS;

    Sammanfattning : Global market development, increasing environmental concerns and incessant risingfuel prices demand for high-grade efficient propulsion systems. This puts high pressureon the propeller designer to develop well-engineered and customized propellerdesign in a short timeframe. LÄS MER

  7. 5. Decentralized Constrained Optimization: a Novel Convergence Analysis

    Författare :Firooz Shahriari Mehr; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constrained optimization; Decentralized optimal transport; Distributed optimization; Multi-agent systems; Convergence analysis; Convex optimization;

    Sammanfattning : One reason for the spectacular success of machine learning models is the appearance of large datasets. These datasets are often generated by different computational units or agents and cannot be processed on a single machine due to memory and computing limitations. LÄS MER
