4. 2. Machine tool vibrations and violin sound fields studied using laser vibrometry

   Author : Kourosh Tatar; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

   Abstract : The knowledge of the dynamic behaviour of a milling process is very important for finding an optimum process window. In today's manufacturing industry the machining parameters are often predicted using experimental data from non-rotating spindles. READ MORE

5. 3. Spindle vibration and sound field measurement using optical vibrometry

   Author : Kourosh Tatar; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Mechanical systems often produce a considerable amount of vibration and noise. To be able to obtain a complete picture of the dynamic behaviour of these systems, vibration and sound measurements are of significant importance. Optical metrology is well-suited for non-intrusive measurements on complex objects. READ MORE

6. 4. Pharmacology and resistance mechanisms of nucleoside analogues and topoisomerase II interactive agents : studies on human leukemia cells with a focus on cross-resistance

   Author : Kourosh Lotfi; Rolf Larsson; Linköpings universitet; []
   Keywords : Nucleoside analogue; cross-resistance; multidrug resistance; deoxycytidine kinase; leukemia; anthracyclines; P-glycoprotein; MEDICINE; MEDICIN;

   Abstract : The purpose of this thesis was to elucidate mechanisms of action and resistance of clinically relevant nucleoside analogues and topoisomerase interactive agents in human leukemia cell lines and leukernia cells isolated from peripheral blood of leukemia patients. Interactions and cross-resistance patterns of these different cytotoxic drug families were also studied since these drugs are usually administrated in combination in the clinic. READ MORE

7. 5. Differential railway track settlement in a transition zone – Field measurements and numerical simulations

   Author : Kourosh Nasrollahi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre Bragg grating sensors; dynamic vehicle–track interaction; heavy haul traffic; non-linear track model; 3MB slab track; Transition zone; empirical settlement model; condition monitoring;

   Abstract : In a transition zone between two different railway track forms, there is a discontinuity in track structure leading to a gradient in track stiffness. Examples include transitions between different superstructures, e.g., slab track to ballasted track, and/or between different substructures, e. READ MORE
