On‐site non‐destructive determination of the remanent magnetization of archaeological finds using field magnetometers
; ; ; ; ; ; (Archaeological Prospection, 2021-09-30)
The determination of the natural remanent magnetization (NRM) of archaeological features can be used for magnetic modelling, joining of shards, archaeomagnetic dating or the investigation of the firing–cooling–collapsing ... -

Operation and Cost Analysis of a Partly Mechanized Small Scale Gold Mine in Ghana
(2013-09-02)The economically successful operation of partly mechanized small scale mines in Ghana could fill the gap between large scale, industrial and foreign controlled mining operations and the artisanal (or "galamsey") small scale ... -
Operator-splitting methods for wave-equations
(Humboldt-Univ., Berlin2007)The motivation to our studies came from simulation of earth-quakes, that are modeled with elastic wave equations. In our paper we focus on the study of the stiff problems for the wave-equations. Due to this contribution ... -
Opportunistic Constant Target Matching—A New Method for Satellite Intercalibration
; ; ; ; ; (Earth and Space Science, 2020)
Opportunistic constant target matching is a new method for satellite intercalibration. It solves a long-standing issue with the traditional simultaneous nadir overpass (SNO) method, namely, that it typically provides only ... -
Opportunities and Challenges for Paleoaltimetry in “Small” Orogens: Insights From the European Alps
; Ehlers, T. A.; Mutz, S. G.; ; Krsnik, E.; (Geophysical Research Letters, 2020-02-10)
Many stable isotope paleoaltimetry studies have focused on paleoelevation reconstructions of orogenic plateaus such as the Tibetan or Andean Plateaus. We address the opportunities and challenges of applying stable isotope ... -
Optical clock technologies for global navigation satellite systems
; ; ; ; ; ; ; ; ; ; ; ; ; ; (GPS Solutions, 2021-04-05)
Future generations of global navigation satellite systems (GNSSs) can benefit from optical technologies. Especially optical clocks could back-up or replace the currently used microwave clocks, having the potential to improve ... -
Optical variability of counterparts of ROSAT X-ray sources near the north ecliptic pole
(Univ. Berlin, 2005)Optical counterparts of X-ray selected sources to a large part consist of active galactic nuclei (AGN). A large proportion of these counterparts turns out to be optically variable, and because the timescales and manner of ... -

Optimising the Design of Fe0-Based Filtration Systems for Water Treatment: The Suitability of Porous Iron Composites
Rahman, Mohammad Azizur; Karmakar, Shyamal; Salama, Heba; Gactha-Bandjun, Nadège; Btatkeu, Brice Donald; (Journal of Applied Solution Chemistry and Modeling, 2013-08-31)
This study assessed the functionality of metallic iron (Fe0) filtration systems using porous iron composite (PIC) as an alternative to granular Fe0/aggregate mixtures. The usage of PIC for water treatment has many challenges ... -
Optimization-based decision-making models for disaster recovery and reconstruction planning of transportation networks
(Natural Hazards, 2020-07-26)The purpose of this study is to analyze optimization-based decision-making models for the problem of Disaster Recovery Planning of Transportation Networks (DRPTN). In the past three decades, seminal optimization problems ... -
Optimized extraction of dimension stone blocks
(Environmental Earth Sciences, 2010)The profitable production of dimension stone mainly depends on the extractable block size. The regularity and volume of the blocks are of critical importance, and are controlled by the three-dimensional pattern of the ... -
Optimized reconstruction of the crystallographic orientation density function based on a reduced set of orientations
(Journal of Applied Crystallography, 2020)Crystallographic textures, as they develop for example during cold forming, can have a significant influence on the mechanical properties of metals, such as plastic anisotropy. Textures are typically characterized by a ... -
