In Finland, coronary artery disease (CAD) is the main cause of death among the middle-aged population. The exercise electrocardiographic (ECG) test is the most widely used non-invasive method of assessing CAD. However, ...

An organization is a system of activities that consists of two or more persons, organizations or both. It has certain goals it is aiming to achieve. An organization is continuously and in most cases consciously coordinated ...

Multiphase flows are present in numerous industrial processes. Knowledge of multiphase flow phenomena makes it possible to control and optimize the process parameters. Process optimization saves energy costs, improves ...

Finnish multi-storey residential buildings have been built of precast concrete panels since the 1960’s. Half of these buildings, which for the most part are located in suburbs, were built in the fairly short period 1960-1979. ...

The purpose of this thesis is to study properties of the EEG signal recorded during anesthesia or sedation. The main emphasis was put on the regularity/complexity analysis of the EEG during gradually deepening sedation and ...

Tissue engineering is expected to fulfill its promises to produce knowledge, methods, and products that would benefit the health care sector. The need of a degradable construct is a necessity when trying to grow a living ...

This thesis concentrates on mathematical modelling of a grinding system consisting of a grinding machine-tool and a thin-walled roll as a work piece. In this system the roll is subjected to process, grinding forces produced ...

New insulation materials can be tailored by compounding nanofillers and polymer materials. The advantageous changes in properties of polymer nanocomposites can be explained by the large interface area of the nanofillers. ...

The unique and tailorable properties of metal nanostructures show great prospects for future nanophotonics applications. However, the complicated interaction between the nanostructures and the electromagnetic field has ...

Photoinduced intermolecular energy and electron transfers in organic multilayered thin films were studied using electrical and spectroscopic methods. Intra- and interlayer processes were mainly investigated by the time-resolved ...
