In this work, physical phenomena related to the growth and phase formation of alumina, Al2O3, are investigated by experiments and computer calculations. Alumina finds applications in a wide variety of areas, due to many beneficial properties and several existing crystalline phases. For example, the α and κ phases are widely used as wear-resistant coatings due [...]
On optical methods for intracerebral measurements during stereotactic and functional neurosurgery: Experimental studies
Radio frequency (RF) lesioning and deep brain stimulation (DBS) are the two prevailing surgical treatments for movement disorders within the field of stereotactic and functional neurosurgery. For RF-lesioning, a small volume of brain tissue is coagulated and knowledge of the lesion size and growth is of great importance for the safety and outcome of the [...]
Hybrid Free-Space and Radio Frequency Switching
The characterization and switching system for a hybrid Free-Space Optical (FSO) with Radio Frequency (RF) backup link is described. Such hybrid systems are used to take advantage of the large bit rates achieved with FSO while maintaining high reliability with a RF backup. In this project, monitoring and switching are controlled by a program that [...]
