1. High frequency electronic packaging : SBU-materials, material characterization, simulation and processing
Sammanfattning : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both High Density Interconnects (HDI) and high frequency (HF) devices has led to the search for new: materials, material combinations, methods, processes and production equipment.

2. High-Frequency ECG in Ischemic Heart Disease
Sammanfattning : Analysis of high-frequency QRS components (HF-QRS) is one of the emerging methods for increasing the diagnostic performance of the electrocardiogram (ECG). The overall objective of the thesis is to investigate whether analysis of HF-QRS has the ability to provide information about ischemic heart disease and so serve as an adjunctive diagnostic tool in several clinical situations.

3. Optical interconnects and high frequency electronic packaging : SBU-materials, material characterization, LAP- & microprocessing
Sammanfattning : The main objective of this thesis is to discuss and demonstrate optical interconnect technologies. These can be used to enhance the data throughput capacity of future printed circuit boards and backplanes, i.e. exchange Copper conductors with light conductors. LÄS MER
4. High frequency monoloithic integrated circuits for communication systems
Sammanfattning : The wavelengths of interest in today's communication systemfront-ends are in the same order of magnitude as the availabledevices and circuit sizes. So the wave nature of theinformation can not be neglected. LÄS MER
5. Adjuncts to the Conventional 12-Lead ECG: Assessment of High-Frequency QRS Components and Additional Leads
Sammanfattning : The standard 12-lead electrocardiogram (ECG) is one of the most commonly used methods for diagnosing heart disease. Standard ECG is not always optimal, however, and new ECG methods can provide additional information. Analysis of high-frequency QRS components (HF-QRS) has been shown to increase the diagnostic performance of the ECG. LÄS MER
