Practical Jamming of a Commercial 5G Radio System at 3.6 GHz
(2022-09-22)Fifth-generation (5G) mobile technology has attracted interest from armed forces worldwide due to its many new possibilities for communication. Military operations may face threats in the electromagnetic spectrum, such as ... -
Spin-vibronic interaction induced reverse intersystem crossing: A case study with TXO-TPA and TXO-PhCz molecules
(2022-11-01)We highlight the important roles the direct spin–orbit (DSO) coupling, the spin-vibronic (SV) coupling, and the dielectric constant of the medium play on the reverse intersystem crossing (RISC) mechanism of TXO-TPA and ... -
NATO Core Services profiling for Hybrid Tactical Networks -Results and Recommendations
(2021-07-21)The NATO Research Task Group IST-150 "NATO Core Services profiling for Hybrid Tactical Networks" had Federated Mission Networking (FMN) as the main context and motivation for its work. IST-150 intended to investigate Core ... -
Understanding the Threat of Nuclear, Biological and Chemical Warfare
(2021)Weapons of mass destruction are not merely Cold War relics. Recent years have seen the use of biological and chemical agents in the United States, Syria, Malaysia and the United Kingdom. The faltering of strategic arms ... -
Effects of Cultural Diversity on Trust and its Consequences for Team Processes and Outcomes in Ad Hoc Distributed Teams
(2011)This quasi-experimental study explores trust as a mediator, explaining how cultural diversity may affect team processes and outcomes in distributed ad hoc teams. Data were collected both through self-report and direct ... -
Organizational flexibility from a network organizational perspective: a study of central predictors and moderating factors in military contexts
(2013-10-28)Purpose – The purpose of this paper is to focus on organizational flexibility and explore its antecedents, organizational structure, and processes, as proposed by network organization theories. The study also explores the ... -
Comparison of simulated and measured ISAR images flow of a ship at sea
(2021-07-02)The aim of this work is to simulate a flow of ISAR images for a ship at sea seen from an airborne radar, in rigorously the same configuration as it has been measured by a real SAR using the recorded motion data of both ... -
A Status Update on Quantum Safe Cryptography
(2021-07-20)There is an ongoing effort to standardize asymmetric cryptography that should not be attackable by a quantum computer. The process is now into its final rounds. From 69 initial submissions from academia and industry, a ... -
Modeling potential masking of echolocating sperm whales exposed to continuous 1-2 kHz naval sonar
(2021-04-30)Modern active sonar systems can (almost) continuously transmit and receive sound, which can lead to more masking of important sounds for marine mammals than conventional pulsed sonar systems transmitting at a much lower ... -
Colliding Pulse Mode Locking and Nonequilibrium Carrier Dynamics within Vertical External-Cavity Surface-Emitting Lasers
(2022-08-02)The complex nonlinear dynamics of colliding counterpropagating ultrashort laser pulses circulating in a vertical external-cavity surface-emitting ring laser cavity are captured by a first-principles quantum-mechanical ... -
3D Rendering of Shipwrecks from Synthetic Aperture Sonar
(2021-10-25)Synthetic aperture sonar (SAS) bathymetric mapping provides centimeter-scale horizontal resolution of the seafloor. Typically, SAS data has been visualized as 2D images or gridded 2.5D surfaces, but it can also be plotted ... -
Ultrafast Pulse Compression in Bulk with > 20 Times Spectral Broadening Factor from a Single Stage
(2021-11-01)We introduce the combination of multi-pass cell and multi-plate spectral broadening. We demonstrate the compression of 110-μJ pulses from 900-fs to 60-fs in a single stage and report broadening to 38-fs transform-limit by ... -
Discrete Fourier Transform with Neural Networks
(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 ... -
