Topographiemessungen technischer Oberflächen mit einer Streulichtanordnung (Topography Measurements of Engineering Surfaces with Optical Scatterometry)

Autor: Albrecht Dipl.-Ing. Dr. Hertzsch, H. Truckenbrodt, K. Hehl, Knut Kröger

Publikováno v: tm - Technisches Messen. 70:4-9

Gedrehte Oberflächenprofile besitzen periodische und zufällige Rauheitskomponenten. Um den Drehprozess und damit den Werkzeugverschleiß zu überwachen, ist prozessnah der mittlere periodische Profilanteil zu messen. Es wird eine optische Messmetho

Airborne gravimetry used in precise geoid computations by ring integration

Autor: A. Gidskehaug, A. H. W. Kearsley, René Forsberg, Uwe Meyer, K. Hehl, Arne Vestergaard Olesen, Luísa Bastos

Publikováno v: Technical University of Denmark Orbit

Two detailed geoids have been computed in the region of North Jutland. The first computation used marine data in the offshore areas. For the second computation the marine data set was replaced by the sparser airborne gravity data resulting from the A

Energy loss in a planar waveguide caused by a high refracting and absorbing overlay

Autor: W. Karthe, B. Gotz, B. Martin, K. Hehl

Publikováno v: Journal of Lightwave Technology. 11:1447-1452

An explanation of the mode behavior in dielectric waveguides with an absorbing, high-refractive-index cladding is given. By considering the total waveguiding system as two separate waveguides, it is possible to attribute the behavior of the complex r

Chondrom im Bereich des Felsenbeines

Autor: K. Hehl, Klaus Kraft, U. Kunz, Heinz Maier, Matthias Tisch

Publikováno v: Laryngo-Rhino-Otologie. 76:371-373

INTRODUCTION Cartilaginous tumors of the mid-face and the skull base are rare. CASE REPORT For the first time, a case report of a chondroma of the base of the ear in a 56-year-old woman is presented. In 1974 the patient developed a facial nerve paral

Rekonstruktion des weichen Gaumens mit dem mikrovaskularisierten Radialislappen*

Autor: K. Hehl, H. Maier

Publikováno v: Laryngo-Rhino-Otologie. 75:769-771

BACKGROUND A new technique for reconstruction of the soft palate using a folded microvascularized radial forearm flap is described. PATIENTS The method has been used in 16 patients to date. RESULTS There was no loss of the transplant. Only three pati
