    Sammanfattning : The advent of multicore systems spurred great interest in Transactional Memory (TM). TM is a parallel programming paradigm that coordinates concurrent threads by incorporating transactions into programming languages. LÄS MER

  3. 22. Data Abstraction and Pattern Identification in Time-series Data

    Författare :Prithiviraj Muthumanickam; Matthew Cooper; Katerina Vrotsou; Aida Nordman; Jimmy Johansson; Anders Ynnerman; Silvia Miksch; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Data sources such as simulations, sensor networks across many application domains generate large volumes of time-series data which exhibit characteristics that evolve over time. Visual data analysis methods can help us in exploring and understanding the underlying patterns present in time-series data but, due to their ever-increasing size, the visual data analysis process can become complex.

  4. 23. Knowledge elicitation as abstraction of purposive behaviour

    Författare :Anton Axelsson; Anders Arweström Jansson; Mats Lind; Annika Wallin; John Flach; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; knowledge elicitation; expertise; context; human factors; Computer Science with specialization in Human-Computer Interaction; Datavetenskap med inriktning mot människa-datorinteraktion;

    Sammanfattning : Researchers use knowledge elicitation methods to document expert knowledge for the primary purpose of understanding cognitive processes and with this understanding, technical solutions to resolve human factors issues can be produced. This dissertation offers a novel perspective on knowledge elicitation as an abstraction process. LÄS MER

  5. 24. Raising Abstraction of Timing Analysis through Model-Driven Engineering

    Författare :Alessio Bucaioni; De-Jiu Chen; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning :  The complexity of software running on vehicular embedded systems is constantlyincreasing and this negatively affects its development costs and time tomarket. One way to deal with these issues is to boost abstraction in the formof models to (i) ease the reasoning about the system architecture, (ii) automatecertain stages of the development, (iii) early detect flaws in the system architecturethrough fundamental analysis and (iv) take appropriate countermeasuresbefore the system is implemented.

  7. 25. Organomolybdenum Complexes in Organic Synthesis- New methods for the Preparation of Cationic Diene Complexes and Applications to Synthesis

    Författare :Emelie Bjurling; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; indoles; carbenium ions; hexafluoroisopropanol; hydride abstraction; molybdenum; cationic diene complexes;

    Sammanfattning : Indolyl substituted pyranyl- and cyclohexenyl molybdenum complexes were synthesised through stereoselective nucleophilic addition of indoles to the corresponding cationic 2H-pyran or cyclohexadiene molybdenum complex. Decomplexation of an allylic molybdneum complex by treatment with iodine gave 1-(4-iodo-2-cyclohexenyl)-1H-indole-3-carbonitrile in high regio-selectivity. LÄS MER
