Notched Fatigue Behaviour of Additively Manufactured Inconel 718
(Master thesis, 2018)Fatigue behavior for different notch geometries of additively manufactured Inconel 718 produced by Selective Laser Melting is investigated at room temperature. Additive manufacturing enables complex geometries in components ... -
Notched graphite under multiaxial loading
(Journal article; Peer reviewed, 2017)Cylindrical specimens made of polycrystalline graphite and weakened by circumferential V-notches under mixed mode I/III loading were studied in this research. Different geometries of V-notches varying the notch opening ... -
Notched Ti-6Al-4V titanium bars under multiaxial fatigue: Synthesis of crack initiation life based on the averaged strain energy density
(Journal article; Peer reviewed, 2018)The fatigue life of notched components subjected to multiaxial loading conditions may be influenced by extrinsic mechanisms operating during crack propagation phase, such as sliding contact, friction and meshing between ... -
A note on Bohr’s theorem for Beurling integer systems
(Journal article; Peer reviewed, 2023)Given a sequence of frequencies , a corresponding generalized Dirichlet series is of the form . We are interested in multiplicatively generated systems, where each number arises as a finite product of some given ... -
Note on estimating bed shear stress caused by breaking random waves
(Peer reviewed; Journal article, 2021)This note presents a method of how the bed shear stress caused by breaking random waves on slopes can be estimated. This is obtained by adopting the Sumer et al. (2013) bed shear stress formula due to spilling and plunging ... -
A note on Real line bundles with connection and Real smooth Deligne cohomology
(Peer reviewed; Journal article, 2024)We define a Real version of smooth Deligne cohomology for manifolds with involution which interpolates between equivariant sheaf cohomology and smooth imaginary-valued forms. Our main result is a classification of Real ... -
Note on seabed shear stress beneath bichromatic and bidirectional waves for large bed roughness
(Peer reviewed; Journal article, 2023)The seabed shear stress beneath bichromatic and bidirectional waves is presented. The approach is analytical using the constant time-invariant eddy viscosity representation of Christoffersen and Jonsson (1985) for rough ... -
A note on the mean values of the derivatives of ζ/ζ
(Peer reviewed; Journal article, 2022)Assuming the Riemann hypothesis, we obtain a formula for the mean value of the -derivative of , depending on the pair correlation of zeros of the Riemann zeta-function. This formula allows us to obtain new equivalences ... -
Note on the resonance method for the Riemann zeta function
(Journal article; Peer reviewed, 2018)We improve Montgomery’s Ω-results for |ζ(σ + it)| in the strip 1/2 σ 1 and give in particular lower bounds for the maximum of |ζ(σ+it)| on √ T ≤ t ≤ T that are uniform in σ. We give similar lower bounds for the maximum of ... -
A note on the zeros of approximations of the Ramanujan Ξ−function
(Peer reviewed; Journal article, 2020)In this paper we review the study of the distribution of the zeros of certain approximations for the Ramanujan Ξ-function given by Ki (Ramanujan J 17(1):123–143, 2008), and we provide new proofs of his results. Our approach ... -
Note Taking and Sharing with Digital Pen and Paper.: Designing for Practice Based Teacher Education.
(Master thesis, 2006)This thesis is a continuation of my previous work `Supporting Notetaking with Digital Writing System: the case of teacher education . The main goal of this thesis is to design a customized digital pen and paper based note ... -

Notes on Computational Uncertainties in Probabilistic Risk/Safety Assessment
(Journal article; Peer reviewed, 2018)In this article, we study computational uncertainties in probabilistic risk/safety assessment resulting from the computational complexity of calculations of risk indicators. We argue that the risk analyst faces the fundamental ... -
Notes on Early Land Plants Today*. 81. Lectotypification of some names in Frullania
(Peer reviewed; Journal article, 2023)Five names in Frullania, F. convoluta Lindenb. et Hampe, F. herzogiana Steph. 1911 (= F. rio-janeirensis (Raddi) Ångstr., syn. nov.), F. herzogiana Steph. 1916 (= F. convoluta), F. convoluta var. ampliata Herzog (= F. ... -
Notes on Early Land Plants Today. 82. Frullanoides chinantlana (Gottsche) comb. nov., an older name for Frullanoides tristis (Steph.) van Slageren
(Peer reviewed; Journal article, 2023)Frullanoides tristis (Steph.) van Slageren is a well-established taxon and the name has been used frequently since the revision of the genus by van Slageren (1985). But there is a nomenclature problem with the name as van ... -
Notes on Early Land Plants Today. 83. Re-instatement of Lejeunea parvisaccata
(Peer reviewed; Journal article, 2023)Mizutani (1970) introduced a new name, Lejeunea micholitzii Mizut., when transferring Hygrolejeunea parvisaccata Steph. to Lejeunea Lib. since Lejeunea parvisaccata (Steph.) Steph. was blocking the name in Lejeunea. The ... -
Notes on Early Land Plants Today. 84. Cheilolejeunea solariae, nom. nov. for Strepsilejeunea subcrenulata Herzog
(Peer reviewed; Journal article, 2023)Grolle (1989) united Strepsilejeunea subcrenulata Herzog with the younger name Cheilolejeunea papillata Solari. However, transferring the former name to Cheilolejeunea was blocked by the existence of the earlier name ... -
Notes on Early Land Plants Today. 85. Metzgeria warnstorffii, an earlier name for the African Metzgeria madagassa
(Journal article; Peer reviewed, 2023)Kuwahara (1984) synonymized Metzgeria madagassa Steph. and Metzgeria thomeensis Steph. under the name Metzgeria australis Steph. So (2004) rejected this synonymy and recognized Metzgeria madagassa from Africa (excluding ... -
