  1. 1. Nanoindentation characterization of high chromium white cast iron for assessment of machining performance

    Författare :Ling Chen; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanoindentation; FEM; Characterization; High chromium cast iron; Machining; Grid nanoindentation;

    Sammanfattning : As modern production moves towards higher efficiency and cost effectiveness, machining difficult-to-cut materials becomes an increasing challenge. Quickly and reliably characterizing the properties of materials could significantly improve the performance of machining processes in terms of their efficiency and production cost. LÄS MER

  3. 2. p53 Alterations in Human Skin : A Molecular Study Based on Morphology

    Författare :Ling Gao; Christer Bush Bush; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; p53; skin; mutation; carcinogenesis; microdissection; UV; Basal cell cancer BCC ; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Mutation of the p53 gene appears to be an early event in skin cancer development. The present study is based on morphology and represents a cellular and genetic investigation of p53 alterations in normal human skin and basal cell cancer. LÄS MER

  4. 3. Hydrodynamic Modelling of Wave Power using Electrical Equivalent Circuit Theory

    Författare :Ling Hai; Mats Leijon; Rafael Waters; Lars-Göran Westerberg; Uppsala universitet; []
    Nyckelord :wave energy; hydrodynamic modelling; electric circuit; force and power analysis;

    Sammanfattning : Ocean wave energy can be harnessed and converted into electric energy nowadays. This provides a possibility for populations that live on islands or along coastlines to utilize the renewable and safe power produced by ocean waves. LÄS MER

  5. 4. Modelling Wave Power by Equivalent Circuit Theory

    Författare :Ling Hai; Mats Leijon; Rafael Waters; Yongliang Zhang; Uppsala universitet; []
    Nyckelord :Wave energy; hydrodynamics; electric circuit; electrical analogy; energy absorption; force; system modelling; Simulink; engineering science; renewable energy; Teknisk fysik med inriktning mot elektricitetslära; Engineering Science with specialization in Science of Electricity;

    Sammanfattning : The motion of ocean waves can be captured and converted into usable electricity. This indicates that wave power has the potential to supply electricity to grids like wind or solar power. A point absorbing wave energy converter (WEC) system has been developed for power production at Uppsala University. LÄS MER

  7. 5. A value-based indexing technique for time sequences

    Författare :Ling Lin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A time sequence is a discrete sequence of values, e.g. temperature measure ments, varying over time. Conventional indexes for time sequences are built on the time domain and cannot deal with inverse queries on time sequences under some interpolation assumptions (i. LÄS MER
