2. Rheology of cement grout : Ultrasound based in-line measurement technique and grouting design parameters
Sammanfattning : Grouting is performed in order to decrease the permeability and increase the stiffness of the material, especially soil and rock. For tunnelling and underground constructions, permeation grouting is done where cement based materials are pumped inside drilled boreholes under a constant pressure, higher than the ground water pressure.

Sammanfattning : This thesis presents some new techniques that were developedfor continuous chemical analysis of a paper furnish. First, ageneral background is presented, covering topics from theorigins of papermaking to present day. LÄS MER
4. Experimental Studies of Separated Flow and Heat Transfer in a Ribbed Channel
Sammanfattning : The main concern of this thesis is to experimentally investigate the turbulent flow and heat transfer in a ribbed channel. Such flows are encountered in many engineering applications, e.g., gas turbine cooling. LÄS MER
5. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg
Sammanfattning : The purpose of this thesis was to validate a new non-invasive photoplethysmography (PPG) method for measuring relative changes in local muscle blood flow (MBF) in the human leg. Experimental conditions expected to impede or increase local MBF were used to test responsiveness of the PPG. LÄS MER
