Cryogenic vs. absorption biogas upgrading in liquefied biomethane production – An energy efficiency analysis
(Journal article; Peer reviewed, 2019)Production of liquefied biomethane (LBM) from biogas comprises two major energy intensive processes; upgrading to increase the methane concentration and refrigeration to liquefy the upgraded biogas. Amine-based absorption ... -
Cryptanalysis of a generic one-round key exchange protocol with strong security
(Journal article, 2017)In Public-Key Cryptography (PKC) 2015, Bergsma et al. introduced an interesting one-round key exchange protocol (which will be referred to as BJS scheme) with strong security in particular for perfect forward secrecy (PFS). ... -
Cryptanalysis of a Pseudorandom Generator for Cross-Border E-Commerce
(Journal article; Peer reviewed, 2019)In this paper, we study ciphertext-only cryptanalysis of a cascade of pseudorandom sequence generators employing linear feedback shift registers (LFSRs) with so-called irregular clocking. The cascade of LFSRs is a well-known ... -
Cryptic choice of conspecific sperm controlled by the impact of ovarian fluid on sperm swimming behavior
(Journal article; Peer reviewed, 2013)Despite evidence that variation in male–female reproductive compatibility exists in many fertilization systems, identifying mechanisms of cryptic female choice at the gamete level has been a challenge. Here, under risks ... -
Cryptocurrencies and the threat versus the act event of geopolitical risk
(Peer reviewed; Journal article, 2023)We examine the reactions of the cryptocurrency market to two events that occurred during the escalation of the Russia–Ukraine war in February 2022. Using hourly data, we find that the escalation exerted a negative influence ... -
Cryptographic smooth neighbors
(Peer reviewed; Journal article, 2023)We revisit the problem of finding two consecutive B-smooth integers by giving an optimised implementation of the Conrey-Holmstrom-McLaughlin “smooth neighbors” algorithm. While this algorithm is not guaranteed to return ... -
A Cryptographic Toolbox for Feedback Control Systems
(Peer reviewed; Journal article, 2020)Abstract: Feedback control systems consist of components such as sensory systems, state estimators, controllers, and actuators. By transmitting signals between these components across insecure transmission channels, feedback ... -
Crystal Orientation of Iron Produced by Electrodeoxidation of Hematite Particles
(Journal article, 2013)Electrowinning of iron was conducted in a 50 wt% NaOH-H2O electrolyte with suspended Fe2O3 particles at 110ºC and pure α-Fe films were obtained on a disk cathode with a higher current efficiency than 95%. The Fe2O3 particle ... -
Crystal Phase Mapping by Scanning Precession Electron Diffraction and Machine Learning Decomposition
(Journal article; Peer reviewed, 2018)Analyzing the distribution of crystal phases is required to understand nanostructures. Conventional analysis in the transmission electron microscope (TEM) include acquiring dark-field (DF) images for each expected crystal ... -
Crystal plasticity finite element simulations of pure bending of aluminium alloy AA7108
(Journal article; Peer reviewed, 2015)The crystal plasticity finite element method (CP-FEM) is used to investigate the influence of microstructure on the bending behaviour of the heat treatable aluminium alloy AA7108. The study comprises two materials obtained ... -
Crystal plasticity modeling of microstructure influence on fatigue crack initiation in extruded Al6082-T6 with surface irregularities
(Journal article, 2018)The influence of surface roughness and microstructure heterogeneities in the vicinity of macroscopic stress concentrations are investigated by crystal plasticity simulations. It is shown that in the extruded Al6082-T6 alloy ... -
Crystal Structure Influences Migration along Li and Mg Surfaces
(Peer reviewed; Journal article, 2020)Dendrite formation on Li metal anodes hinders commercialization of more energy-dense rechargeable batteries. Here, we use the migration energy barrier (MEB) for surface transport as a descriptor for dendrite nucleation and ... -
Crystal structure, thermal expansion and electrical conductivity of LaCoxNiyMozO3
(Journal article; Peer reviewed, 2016)The effect of Mo-substitution was investigated for the LaCoxNiyMozO3 system, obtaining single-phase perovskite for Mo-substitutions up to 20 at%. The crystal structure of the perovskite changed from rhombohedral, orthorhombic ... -
Crystalline GaSb-core optical fibers with room-temperature photoluminescence
(Journal article; Peer reviewed, 2018)Glass-clad, GaSb-core fibers were drawn and subsequently laser annealed. The asdrawn fibers were found to be polycrystalline, possess Sb inclusions, and have oxide contamination concentrations of less than 3 at%. Melting ... -
Crystalline symmetry controlled magnetic switching in epitaxial (111) La0.7Sr0.3MnO3 thin films
(Journal article; Peer reviewed, 2015)Mixed-valence manganite thin films are attractive for spintronic devices. Crystalline orientation is a promising route to tailor switching mechanisms, as magnetization reversal depends on the magnetic anisotropy. Here, ... -
