  2. 1. Wheels, Rails and Insulated Joints - Damage and Failure Probability at High Speed and Axle Load

    Author : Johan Sandström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail breaks; probability; railway mechanics; contact mechanics; insulated joints; defects; fatigue;

    Abstract : The thesis deals with some fatigue related problems in railway mechanics related to increased axle loads and speeds. The focus is on defects and discontinuities in the wheel--rail system that affect the risk of fatigue and fracture of railway components such as wheels, rails and insulated joints. READ MORE

  4. 2. Statistical modelling in chemistry - applications to nuclear magnetic resonance and polymerase chain reaction

    Author : Halfdan Grage; Teknisk mikrobiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; operationsanalys; programmering; aktuariematematik; programming; actuarial mathematics; Statistics; operations research; experimental design.; logistic regression; detection probability; region of operability; sampling. Diagnostic PCR; Cramér-Rao bounds; maximum likelihood estimation; NMR spectroscopy; Gaussian noise;

    Abstract : This thesis consists of two parts with the common theme of statistical modelling in chemistry. The first part is concerned with applications in nuclear magnetic resonance (NMR) spectroscopy, while the second part deals with applications in polymerase chain reaction (PCR). READ MORE

  5. 3. A new approach for considering the interference impact on digital radio systems from complex interference environments

    Author : Kia Wiklundh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; minimum shift keying; class A; amplitude probability distribution; bandwidth conversion; Gaussian approximation; emission; non-Gaussian interference; performance estimation; man-made noise; measurement; emission requirements; micro-wave oven; MSK; coding gain; APD; interference;

    Abstract : Interference from electrical equipment can severely degrade aco-located digital radio receiver. To avoid such performance degradation, it isnecessary to have estimation methods to predict the influence of an interferenceenvironment on a radio receiver. READ MORE

  6. 4. On Performance of Digital Radio Receiver in Non-Gaussian Interference

    Author : Kia Wiklundh; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bandwidth conversion; performance estimation; APD; interference; minimum shift keying; man-made noise; Gaussian approximation; measurement; emission requirements; non-Gaussian interference; micro-wave oven; MSK; amplitude probability distribution; emission;

    Abstract : Interference from electrical equipment can degrade a co-located digital radio receiver severely. To avoid this performance degradation it is necessary to have estimation methods to predict the influence from an interference environment on a radio receiver in advance. READ MORE

  7. 5. Statistical Analysis of Crests and Maxima in Gaussian Seas

    Author : Jesper Rydén; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; physical oceanography; meteorology; Geofysik; programmering; aktuariematematik; fysisk oceanografi; meteorologi; Statistik; operationsanalys; actuarial mathematics; programming; Statistics; operations research; Mathematics; Matematik;

    Abstract : An important problem in ocean engineering is to find distributions for characteristic wave parameters. For wind-generated water waves at deep water, a Gaussian distribution for the wave-surface elevation is considered a reasonable model. READ MORE
