1. On Median and Ridge Estimation of SURE Models
Abstract : This doctoral dissertation is a progressive generalization of some of the robust estimation methods in order to make those methods applicable to the estimation of the Seemingly Unrelated Regression Equations (SURE) models. The robust methods are each of the Least Absolute Deviations (LAD) estimation method, also known as the median regression, and the ridge estimation method. READ MORE

2. Ridge alterations following tooth extraction and implant placement
Abstract : The purpose of the present series of investigations was to study the healing following tooth extraction and implant placement. In an animal model, the healing sequence of tooth extraction sites (Study I), the influence of the periodontal ligament (PDL) on the healing of extraction sockets and the effect of various biomaterial on the healing of bone defects (Study II), and the healing of different bone block grafts placed on the surface of a narrow ridge (Study III) were investigated.

4. Dielectrically Loaded Quad-ridge Flared Horns for Ultra Wideband Reflector Feed Applications in Radio Astronomy
Abstract : Reflector-based radio telescopes are used as tools for observations in both radio astronomy and space geodesy. To observe the weak sources in space, highly sensitive receivers, fronted by optimized reflector feeds, are therefore needed. READ MORE

5. Characterization of losses in ridge, groove and microstrip gap waveguides
Abstract : The gap waveguide is a new technology that recently has been presented as an attractive candidate for applications at millimeter and sub millimeter waves. The waveguide is generated in the gap between a smooth upper metal plate and a ridge (or a groove) in a textured lower metal plate. READ MORE
