  2. 1. Maximum spacing methods and limit theorems for statistics based on spacings

    Author : Magnus Ekström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Estimation; spacings; maximum spacing method; consistency; ^-divergence; goodness of fit; unimodal density; entropy estimation; uniform distribution;

    Abstract : The maximum spacing (MSP) method, introduced by Cheng and Amin (1983) and independently by Ranneby (1984), is a general estimation method for continuous univariate distributions. The MSP method, which is closely related to the maximum likelihood (ML) method, can be derived from an approximation based on simple spacings of the Kullback-Leibler information. READ MORE

  4. 2. The bentonite barrier : microstructural aspects on colloid filtration and radiation effects on bentonite colloid stability

    Author : Michael Holmboe; Mats Jonsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry;

    Abstract : In many countries a multi-barrier concept in a deep geological repository is planned for final disposal of nuclear waste. Many of these different concepts, for example the Swedish KBS-3 model, include an engineered barrier consisting of compacted bentonite. READ MORE

  5. 3. Microfabrication and evaluation of piezoceramic actuators

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Miniature motor; piezomotor; piezoelectric; actuator; assembly; piezoceramic; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : There is an increasing interest for miniaturised actuators in a number of technological fields such as automation or medicine (e.g. prostheses, medical pumps etc.). READ MORE

  6. 4. Experimental Studies of Effusion Cooling

    Author : Bernhard Gustafsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; laser-Doppler anemometry; infrared thermography; film cooling; flow visualization; full coverage film cooling; jet in crossflow; effusion cooling;

    Abstract : The desire to increase the efficiency of jet engines, has led to an increase in the temperature in the combustion chambers and in the turbine stage. There is thus an interest in efficient cooling methods. Film cooling and effusion cooling are often used where there is a great heat load. READ MORE

  7. 5. Experimental Investigations of Heat Transfer in a Channel with Ribs and Obstacle

    Author : Zahra Ghorbani-Tari; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid crystal thermography; ribs; entrance region; control the heat transfer around an obstacle by rib;

    Abstract : This thesis presents experimental investigations of local heat transfer in a rectangular channel (aspect ratio AR = 4) with continuous transverse ribs as well as an obstacle. Liquid crystal thermography (LCT) is employed to obtain the temperature fields in the heat transfer experiments. READ MORE
