High resolution hydrographic reconstructions from the Southeast Pacific spanning Antarctic Warming event A2 (44-48 Kyr BP)
(Master thesis, 2022-10-03)Knowledge about and reconstructions of past climate change is important to distinguish between natural climate variability on various time scales and the more recent man-made climate changes. In this thesis, sub-millennial ... -
High resolution Late-glacial and early-Holocene summer air temperature records from Scotland inferred from Chironomid assemblages
(Peer reviewed; Journal article, 2012-05-18)Lateglacial and early-Holocene mean July air temperatures have been reconstructed, using a chironomid-based inference model, from lake-sediment sequences from Abernethy Forest, in the eastern Highlands of Scotland, and ... -
High resolution sea ice monitoring using space borne Synthetic Aperture Radar
(Doctoral thesis, 2017-12-06)Sea ice represents a major factor in the climate system and updated knowl- edge about sea ice conditions is important for shipping and offshore industry, local communities and others. Due to its remote location and strong ... -
High resolution seismic stratigraphic analysis: An integrated approach to the subsurface geology of the SE Persian Gulf
(Doctoral thesis, 2006-06-30) -
High resolution weather forecasting and predictability - applications in complex terrain
(Doctoral thesis, 2006-11-17) -
High Voltage Direct Current Transmission
(Master thesis, 2019-07-02) -
High voltage electrical discharges in the laboratory
(Master thesis, 2014-12-18)A new phenomenon called terrestrial gamma-ray flashes (TGFs) was discovered early in the 1990s by the NASA satellite Compton Gamma-Ray Observatory. The short-duration bursts of highly energetic gamma-rays are caused by ... -
High Voltage Laboratory Development: An in-depth Description and Report on the Process of Fabricating a Faraday Cage
(Master thesis, 2022-12-16)This thesis examines the quality of protection a Faraday cage provides against electromagnetic fields. The necessary theory to examine and calculate the shielding effectiveness of a Faraday cage, discuss obtained results ... -
High-accuracy phase-field models for brittle fracture based on a new family of degradation functions
(Peer reviewed; Journal article, 2018-02)Phase-field approaches to fracture based on energy minimization principles have been rapidly gaining popularity in recent years, and are particularly well-suited for simulating crack initiation and growth in complex fracture ... -
High-Dimensional Bayesian Network Inference From Systems Genetics Data Using Genetic Node Ordering
(Journal article; Peer reviewed, 2019)Studying the impact of genetic variation on gene regulatory networks is essential to understand the biological mechanisms by which genetic variation causes variation in phenotypes. Bayesian networks provide an elegant ... -
High-elevation limits and the ecology of high-elevation vascular plants: legacies from Alexander von Humboldt
(Journal article; Peer reviewed, 2021)Alexander von Humboldt and Aimé Bonpland in their Essay on the Geography of Plants discuss what was known in 1807 about the elevational limits of vascular plants in the Andes, North America, and the European Alps and suggest ... -
High-frequency internal wave observations in the marginal ice zone
(Journal of Geophysical Research: Oceans;92(C7), Journal article, 1987-06-30) -
A high-granularity digital tracking calorimeter optimized for proton CT
(Journal article; Peer reviewed, 2020)A typical proton CT (pCT) detector comprises a tracking system, used to measure the proton position before and after the imaged object, and an energy/range detector to measure the residual proton range after crossing the ... -
High-latitude cold ion outflow inferred from the Cluster wake observations in the magnetotail lobes and the polar cap region
(Journal article; Peer reviewed, 2021)Cold ions with low (a few eV) thermal energies and also often low bulk drift energies, dominate the ion population in the Earth’s magnetosphere. These ions mainly originate from the ionosphere. Here we concentrate on cold ... -
High-latitude magnetic fields and their time derivatives: interhemispheric similarities
(Peer reviewed; Journal article, 2013-02-19)There are two simple and objective measures of geomagnetic activity: the daily range of field components, and the daily maximum of the time derivative of the field. We study these using data from the geomagnetic latitude ... -
High-order harmonic generation from graphene: Strong attosecond pulses with arbitrary polarization
(Peer reviewed; Journal article, 2013-05-03)We explore high-order harmonic generation (HHG) from a graphene sheet exposed to intense femtosecond laser pulses based on the Lewenstein model. It is demonstrated that the HHG cutoff frequency increases with graphene size ... -
High-performance design patterns for modern Fortran
(Peer reviewed; Journal article, 2015)This paper presents ideas for using coordinate-free numerics in modern Fortran to achieve code flexibility in the partial differential equation (PDE) domain. We also show how Fortran, over the last few decades, has changed ... -
High-precision limits on W–W′and Z–Z′ mixing from diboson production using the full LHC Run 2 ATLAS data set
(Journal article; Peer reviewed, 2020)The full ATLAS Run 2 data set with time-integrated luminosity of 139fb−1 in the diboson channels in hadronic final states is used to probe a simple model with an extended gauge sector (EGM), proposed by Altarelli et al., ... -
High-quality draft genome of the methanotroph Methylovulum psychrotolerans Str. HV10-M2 isolated from plant material at a high-altitude environment
