DFT methods were used to evaluate the type of Jahn-Teller distortion in the low spin d⁷ bis(terpyridine)nickel (III) doublet. The strain of the tridentate terpyridine ligand in bis(terpyridine)nickel(III) leads to longer Ni(III)-N terminal bond lengths than the Ni(III)-N central bonds. In addition, in all DFT optimized bis(terpyridine)nickel (III) molecules, the one set of Ni(III)-N ...

We establish 2-jet determinacy for the symmetry algebra of the underlying structure of any (complex or real) parabolic geometry. At non-flat points, we prove that the symmetry algebra is in fact 1-jet determined. Moreover, we prove 1-jet determinacy at any point for a variety of non-flat parabolic geometries—in particular torsion-free, parabolic contact, and several other classes.

We review computations of joint invariants on a linear symplectic space, discuss variations for an extension of group and space and relate this to other equivalence problems and approaches, most importantly to differential invariants.

Deep embedded clustering has become a dominating approach to unsupervised categorization of objects with deep neural networks. The optimization of the most popular methods alternates between the training of a deep autoencoder and a k-means clustering of the autoencoder’s embedding. The diachronic setting, however, prevents the former to beneft from valuable information acquired by the latter. In ...

Determining the timing of post-Caledonian brittle faulting in northern Norway is important for the understanding of the extensional tectonic evolution of the north Norwegian continental margin. Fault gouges from the Troms and Vesterålen regions of northern Norway yield Carboniferous to Permian and Carboniferous to Cretaceous K–Ar illite ages, respectively. The results show a contrast in fault activity ...

A clustering method that combines an advanced statistical distribution with spatial contextual information is proposed for multilook polarimetric synthetic aperture radar (PolSAR) data. It is based on a Markov random field (MRF) model that integrates a K-Wishart distribution for the PolSAR data statistics conditioned to each image cluster and a Potts model for the spatial context. Specifically, the ...

We report the discovery of three pulsating subdwarf B stars in binary systems observed with the <i>Kepler</i> space telescope during Campaign 5 of K2. EPIC 211696659 (SDSS J083603.98+155216.4) is a g-mode pulsator with a white dwarf companion and a binary period of 3.16 d. EPICs 211823779 (SDSS J082003.35+173914.2) and 211938328 (LB 378) are both p-mode pulsators with main-sequence F companions. The ...

I løpet av de siste årene har en erfart usedvanlig mange flombaserte hendelser i Norge. Vi kan samtidig forvente ytterligere eksponering for flombaserte hendelser i framtiden. Ulike klimaframskrivinger og prognoser viser blant annet at havnivået vil stige og ekstreme regnværsperioder vil komme oftere. I denne oppgaven har jeg undersøkt følgende problemstilling: På hvilken måte kan forebyggende arbeid ...

Landbruket er blant de mest ulykkeutsatte næringene i Norge og gårdsbruk som små bedrifter har særlige utfordringer med å gjøre arbeid knyttet til både regulering av sikkerhet og sikkerhetsstyring. Forståelse for regulerings- og sikkerhetsarbeidet, lange arbeidsdager, mye alenearbeid og at én person ofte har ansvar for hele kjeden av sikkerhetsrelaterte aktiviteter er noen av forklaringene på hvorfor ...
