Efficient Implementation of Elliptic Curve Cryptography on FPGAs
(2007)
This work presents the design strategies of an FPGA-based elliptic curve co-processor. Elliptic curve cryptography is an important topic in cryptography due to its relatively short key length and higher efficiency as ...
Dual-Mode Laser for a Photonic Local Oscillator in the Submillimeter Band and The Molecular Composition of an Oxygen-Rich Asymptotic Giant Branch Star
(2007)
Generation of local oscillator power at Terahertz frequencies with conventional techniques is difficult and expensive. In this thesis, I demonstrate steps towards a THz source using the photonic local oscillator technique ...
Sperm competition in the scorpionfly Panorpa communis (Mecoptera, Insecta)
(2007)
The aim of the present study was to investigate the basal mechanism of sperm competition in the European scorpionfly Panorpa communis. Within three laboratory experiments, I used five newly developed microsatellite ...
Rigidity and Exotic Models for the K-local Stable Homotopy Category
(2007)
When two stable model categories C and D are Quillen equivalent, their homotopy categories Ho(C) and Ho(D) are equivalent as triangulated categories. But is the converse also true?
For the stable homotopy category ...
For the stable homotopy category ...
New Approach to Arakelov Geometry
(2007)
This work is dedicated to a new completely algebraic approach to Arakelov geometry, which doesn't require the variety under consideration to be generically smooth or projective. In order to construct such an approach we ...
Landscape ecology
(2007)
This volume of the Colloquium Geographicum is based on a conference meeting held in
Bonn in February 2005. The aim was to summarise current research philosophies in
German landscape ecology. We tried to ascertain if there ...
Persistence and Transformation in the Eastern Hindu Kush: A Study of Resource Management Systems in Mehlp Valley, Chitral, North Pakistan
(2007)
In the vogue of modernisation and economic integration of the peripheral and remote areas, the whole society in Odier, together with its centuries'-old traditional practices, is at a crossroads. In this transitional process, ...
Rockglacier Kinematics in a High Mountain Geosystem
(2007)
The study presents a regional approach for the quantification of rockglacier creep in a high mountain geosystem (Turtmann valley, Swiss Alps).
By a combination of different methods, rockglacier movements were ...

Permafrost und Sedimenthaushalt in einem alpinen Geosystem
(2007)
Große Teile alpiner Permafrostgebiete liegen in einer klimatischen Grenzlage, in der bei fortschreitender Temperaturerhöhung mit dem sukzessiven Abschmelzen der Permafrostvorkommen zu rechnen ist. Die Ermittlung der ...
