  2. 1. Some new results concerning general weighted regular Sturm-Liouville problems

    Author : Mervis Kikonko; Lars-Erik Persson; Peter Wall; Angelo B. Mingarelli; Alexey Karapetyants; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Partial differential equations; Sturm-Liouville problem; Right-definite; left-definite; non-definite; indefinite; Dirichlet problem; spectrum; eigenvalues; non-real eigenvalues; Richardson number; Richardson index; turning point; Mathematics; Matematik;

    Abstract : In this PhD thesis we study some weighted regular Sturm-Liouville problems in which the weight function takes on both positive and negative signs in an appropriate interval [a,b]. With such  problems there is the possible existence of non-real eigenvalues, unlike in the definite case (i.e. READ MORE

  4. 2. End-of-life care in a Swedish county : patterns of demographic and social conditions, clinical problems and health care use

    Author : Eva Jakobsson; Högskolan i Skövde; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; End-of-life; end-of-life care; demographics; social conditions; health care utilization; places of death; clinical problems; turning point; Nursing; Omvårdnad; Humanities and Social sciences; Humaniora-samhällsvetenskap; end-of-life; end-of-life care; demographics; social conditions; health care utlization; places of death; clinical problems; turning point;

    Abstract : There is broad consensus in both international and national policy statements that care provided at end-of-life should be different from care provided during other periods of life. There is a need for comprehensive knowledge about the broad population of individuals who access the public health care system during the last period of life. READ MORE

  5. 3. Performance Testing of Cutting Fluids and Tool Holders in Metal Cutting

    Author : Varun Nayyar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip Microstructure; Torque; Drilling; Compressed air; Turning; Tool-holding; Force.; Tapping; Keyword: Cutting Fluid;

    Abstract : ABSTRACTThe metal cutting industry has evolved over the last century to the point where an increasing range and complexity of tool holding systems and cutting fluids are available for metal machining in the market. Most of the companies report their cutting fluid cost to be between 7 -17 % of the manufacturing cost. READ MORE

  6. 4. Hard Turning of Bearing Steels. Controlling residual stress and improving fatigue life

    Author : Michael Jacobson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray diffraction; bearing steel; residual stress; fatigue life; cutting conditions; hard turning;

    Abstract : There are many different precision mechanical components such as bearings, fuel injectors, gears and hydraulic components, which are made of hardened steels, and have to be machined to a high degree of precision. Traditionally these components are being ground. READ MORE

  7. 5. On Turning Point Detection in Cyclical Processes.With applications to the monitoring of business cycles

    Author : Eva M. Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Business cycles; Turning point detection; Monitoring; Non-parametric regression; Statistical surveillance; Likelihood ra;

    Abstract : In many areas it is important to detect the turning points in an on-going process. The main application in this thesis is detection of turns in business cycles. READ MORE
