    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Solid phase peptide synthesis; solid phase organic chemistry; linkers; self-scavenging; safety catch linker; cyclic peptides; reductive acidolysis; disulfides; reduction; metallic zinc; multi-component condensations; combinatorial chemistry; Neurochemistry; Neurokemi;

    Sammanfattning : Solid phase synthesis has become an increasingly important tool in the synthesis of oligopolymers and small organic molecules. This thesis covers three important areas in the solid phase synthesis technique: linker strategies, reduction methods and novel routes to complex heterocycles. LÄS MER

  4. 3. Component Synthesis of Machine Tool and Cutter for Process Optimisation

    Författare :Anders Liljerehn; Chalmers University of Technology; []
    Nyckelord :State-space models; Component synthesis; Experimental modal analysis; System Identification; Receptance coupling; Metal Cutting; Chatter stability;

    Sammanfattning : Metal cutting is today one of the leading forming processes in the manufacturing industry. The metal cutting industry houses several actors providing machine tools and cutting tools with a fierce competition as a consequence. Extensive efforts are made to improve the performance of both machine tools and cutting tools. LÄS MER

  5. 4. Towards decision-making to choose among different component origins

    Författare :Deepika Badampudi; Claes Wohlin; Lech Madeyski; Blekinge Tekniska Högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Component-based software development; component origin; decision-making; snowballing; database search; Bayesian synthesis;

    Sammanfattning : Context: The amount of software in solutions provided in various domains is continuously growing. These solutions are a mix of hardware and software solutions, often referred to as software-intensive systems. Companies seek to improve the software development process to avoid delays or cost overruns related to the software development. LÄS MER

  7. 5. High-Level Synthesis for SiLago : Advances in Optimization of High-Level Synthesis Tool and Neural Network Algorithms

    Författare :Yu Yang; Ahmed Hemani; Zhonghai Lu; Madhura Purnaprajna; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic Design Automation EDA ; Computer Aided Design CAD ; Algorithm-level Synthesis; SiLago; Optimization Techniques; Neural Network; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Embedded hardware designs and their automation improve energy and engineering efficiency. However, these two goals are often contradictory. The attempts to improve energy efficiency often come at the cost of engineering efficiency and vice-versa. High-level synthesis (HLS) is a good example of this challenge. LÄS MER
