(2021-12-10)The discrete Fourier transform is an important computational tool to retrieve the frequency distribution of a sampled signal. Recent years have also witnessed considerable research activity in neural networks as a mean to ... -
Typical Products for Outside Audiences: The Role of Typicality When Products Traverse Countries
(2022-12-02)While organization theorists have established the importance of typicality, most studies examine situations where producers and audiences dwell within the same category system (e.g., a country, industry, or market). ... -
The Motivation to Serve in the Military Among Swedish and Norwegian Soldiers. A Comparative Study
(2020)The geographic location of Sweden and Norway, combined with a deteriorated security situation in the Nordic Region and a renewed focus on national defense, makes the development of their armed forces a hot topic. In ... -
Small-scale fire performance assessment of intumescent coatings on metal tubes containing ammonium nitrate. A stepping-stone towards their application as a fire safety measure on road transportation tanks?
(2021-11)Ammonium nitrate is used in vast amounts globally, first and foremost as a component of fertilizers and explosive formulations. This usage necessitates its transportation which, as for most hazardous materials, involves ... -
Responsible Research and Innovation Associated With Risk Communication and Public Engagement on Health Emergency Preparedness at the Local Level
(2022-04-05)Responsible Research and Innovation (RRI) associated with public health emergency preparedness (PHEP) and response pose major challenges to the scientific community and civil society because a multistakeholder and ... -
SARS-CoV-2 in the Air Surrounding Patients during Nebulizer Therapy
(2022-09-17)Nebulizer therapy is commonly used for patients with obstructive pulmonary disease or acute pulmonary infections with signs of obstruction. It is considered a “potential aerosol-generating procedure,” and the risk of disease ... -
Damper models and their impact on shock response
(2022-10-26)Mechanical vibration and shocks may be devastating, in particular to military equipment. Therefore, vibration and shock damping are of crucial importance to military hardware. Vibrations can cause material fatigue. They ... -
Et tidsskille i europeisk sikkerhetspolitikk. Hvordan krigen i Ukraina bidrar til et nytt grunnlag for det transatlantiske sikkerhetsfellesskapet
(2022-11-14)Med Russlands angrep på Ukraina endres grunnlaget for europeisk sikkerhet og den europeiske sikkerhetsordenen. Tyskland inntar en særstilling i europeisk sikkerhet og med forbundskansler Olaf Scholz’ tale til Forbundsdagen ... -
Equipment to tag, track and collect biopsies from whales and dolphins: the ARTS, DFHorten and LKDart systems
(2022-10-21)Of all animals considered subjects for instrumentation for behavioral or physiological studies, cetaceans probably represent the greatest challenge to the engineer and biologist. The marine environment being harsh to ... -

Vibrational Corrections to NMR Spin-Spin Coupling Constants from Relativistic Four-Component DFT Calculations
(2022-09-22)Zero-point vibrational (ZPV) corrections to the nuclear spin–spin coupling constants have been calculated using four-component Dirac–Kohn–Sham DFT for H2X (where X = O, S, Se, Te, Po), XH3 (where X = N, P, As, Sb, Bi), and ... -
Molecular properties of energetic materials and the use of quantumchemical methods for their determination
(2022-11-11)Energetic materials find countless applications of relevance to the defence sector, as typical classes of energetic materials are propellants, explosives and fuels. To ensure safe handling of such materials, obtaining ... -
Target detection in radars using small neural networks
(2022-08-17)Target detection is an essential part of radar systems. An important objective in radar target detection is to satisfy two often contradictory requirements: a high probability of detection with a low false alarm rate. ... -
