The instrument package SEIS (Seismic Experiment for Internal Structure) with the three very broadband and three short‐period seismic sensors is installed on the surface on Mars as part of NASA's InSight Discovery mission. ... -
Determination of an arrival time cut for the separation of electrons and muons in extensive air showers
(Univ. Siegen, 2006)Extensive air showers measured by the KASCADE-Grande experiment at the Forschungszentrum Karlsruhe are studied with respect to the arrival times of electrons and muons at observation level. KASCADE-Grande is a ground based ... -
Determination of Spatial Scale in Martian Landscape Images Acquired by the Curiosity Rover, and Viewing Image Scale and Target Chemistry Using the ASIC Website
; ; ; ; (Earth and Space Science, 2023-05-11)
Abstract In this paper we describe a method to compute spatial scales for images acquired by ...

Determination of the lunar body tide from global laser altimetry data
; ; ; ; ; ; (Journal of Geodesy, 2020-12-23)
We use global data from the Lunar Orbiter Laser Altimeter (LOLA) to retrieve the lunar tidal Love number h2 and find h2 = 0.0387 ± 0.0025. This result is in agreement with previous estimates from laser altimetry using ... -
Determining the Origin of Tidal Oscillations in the Ionospheric Transition Region With EISCAT Radar and Global Simulation Data
; ; ; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2022-09-30)
At high‐latitudes, diurnal and semidiurnal variations of temperature and neutral wind velocity can originate both in the lower atmosphere (UV or infrared absorption) and in the thermosphere‐ionosphere (ion convection, EUV ... -
Developing a ground-based search system for transits of extrasolar planets
(Univ. Berlin, 2006)The search for extrasolar planets is a relatively new field in astronomical and astrophysical sciences that was boosted by the first discovery of the exoplanet 51 Peg b in 1995 by radial velocity measurements. The short ... -
Development and application of 2D and 3D transient electromagnetic inverse solutions based on adjoint Green functions - a feasibility study for the spatial reconstruction of conductivity distributions by means of sensitivities
(Univ. Köln, 2009)To enhance interpretation capabilities of transient electromagnetic (TEM) methods, a multidimensional inverse solution is introduced, which allows for a explicit sensitivity calculation with reduced computational effort. ... -
Development and Emplacement of Ana Slide, Eivissa Channel, Western Mediterranean Sea
; ; ; ; ; ; (Geochemistry, Geophysics, Geosystems, 2022-11-20)
Submarine landslides can destroy seafloor infrastructures and generate devastating tsunamis. In spite of decades of research into the functioning of submarine landslides there are still numerous open questions, in particular ... -
Development of a methodology for real-time retrieving and viewing of spatial data in emergency scenarios
; ; (Applied Geomatics, 2021-08-06)
Quick response in emergency situations is crucial, because any delay can result in dramatic consequences and potentially human losses. Therefore, many institutions/authorities are relying on development of strategies for ... -
Development of a novel balloon-borne optical sonde for the measurement of ozone and other stratospheric trace gases
(Univ. Bremen, 2005)Ozone, balloon-borne measurements, atmospheric trace gases, concentration profiles, climate change. - In the frame of this work, a new small-size balloon-borne sonde was developed. A miniature grating spectrometer in the ... -
Development of a wide bandwidth array acousto optical spectrometer for the Herschel Satellite Mission
(Univ. Köln, 2005)The Herschel satellite observatory will explore the universe at far-infrared, submillimetre, and millimetre wavelengths. This regime of the electromagnetic spectrum is difficult to observe, because water vapour in the ... -
Development of pull apart basins and associated structures by the Riedel shear mechanism - insight from scaled clay analogue models
(Univ. Bochum, 2006)Die physikalischen und mechanischen Eigenschaften von tonartigen Materialien, die für die Skalierung von Analogexperimenten relevant sind, werden mit Hilfe von Konzepten der modernen Bodenmechanik analysiert. Ein Verfahren ... -
Development of ultrathin niobium nitride and niobium titanium nitride films for THz hot-electron bolometers
(Univ. Köln, 2005)The main focus of this work is the development of ultrathin NbN and NbTiN films. A reproducible and reliable deposition process for ultrathin NbN and NbTiN films for the use in phonon-cooled HEB devices was established. ... -
Diagenetic imprints on magnetic mineral assemblages in marine sediments
(Univ. Bremen, 2006)Diagenesis, Rock magnetism, Marine sediments. - Sediments and sedimentary rocks are important sources for paleomagnetic studies of the geomagnetic field behaviour and of environmental changes. These studies are greatly ... -
Diagnosis of Model Errors With a Sliding Time‐Window Bayesian Analysis
; ; ; (Water Resources Research, 2022-02-17)
Deterministic hydrological models with uncertain, but inferred‐to‐be‐time‐invariant parameters typically show time‐dependent model errors. Such errors can occur if a hydrological process is active in certain time periods ... -
Die Bildung SiO2-reicher Phasen im frühen Sonnensystem
(Univ. Köln, 2003)In meiner Arbeit untersuche ich die Bildung SiO2-reicher Objekte (SRO) in chondritischen Meteoriten (--> Chondrite). Diese Phasen werden nach den heutigen Modellen des frühen Sonnsystems nicht in diesen erwartet. Trotzdem ... -
Die Geothermie-Bohrung Hamburg-Allermöhe - eine Analyse mit Hilfe reaktiver Transportsimulation
(Univ. Aachen, 2006)Die Bohrung Allermöhe 1 bei Hamburg wurde im Jahr 1998 abgeteuft, um aus dem dort in 3300m Tiefe anstehenden Rhät-Sandstein Thermalwasser für geothermische Heizzwecke zu fördern. Porosität und Permeabilität des Speichergesteins ... -
Die Kalenderbriefe des Georg Albrecht Hamberger - im Kontext der Kalenderreform von 1700
(Univ.-Verl. Göttingen, Göttingen, 2012)Mit der päpstlichen Bulle Inter Gravissimas wurde 1582 der nach Papst Gregor XIII. benannte Gregorianische Kalender eingeführt. In Deutschland wurde dieser Kalender anfangs nur von katholisch regierten Ländern übernommen. ...
