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 ...
Tribal engagement strategies in the Islamic Emirate of Azawad
(2022-09-02)
The Tuareg uprising in northern Mali in 2012 culminated in the establishment of the Islamic Emirate of Azawad, a proto-state run jointly by Tuareg Islamists in Ansar Dine and foreign jihadists with connections to al-Qaida ...
VErsatile RAdar – RFSoC based radar demonstrator for multiple applications
(2022-10-04)
The Norwegian Defence Research Establishment (FFI) VeRa (Versatile Radar) is a radar demonstrator for multiple applications based on the 1st generation Xilinx RF System on Chip (RFSoC). This paper describes the hardware ...
A Computational Protocol for Vibrational Circular Dichroism Spectra of Cyclic Oligopeptides
(2022-08-05)
Cyclic peptides are a promising class of compounds for next-generation antibiotics as they may provide new ways of limiting antibiotic resistance development. Although their cyclic structure will introduce some rigidity, ...
Towards Using Reinforcement Learning for Autonomous Docking of Unmanned Surface Vehicles
(2022-06-10)
Providing full autonomy to Unmanned Surface Vehicles (USV) is a challenging goal to achieve. Autonomous docking is a subtask that is particularly difficult. The vessel has to distinguish between obstacles and the dock, and ...
Multiteam Systems Handling Time-Sensitive Targets: Developing Situation Awareness in Distributed and Co-located Settings
(2022-08-04)
There is an increasing interest in how to organize operations carried out by multiteam systems (MTS). Large MTS typically operate with a dedicated integration team, responsible for coordinating the operation. We report a ...
Long-Term Measurements of Tropospheric Scintillation at Very Low Elevation Angles - Initial Analysis
(2022-05-11)
Four years of scintillation measurements at very low elevation angles at Kjeller, Norway are analyzed and compared with the ITU-R model. One year is at Ka band with an elevation angle of 3°, and three years are of simultaneous ...
Adaptive suppression of smart jamming with FDA permutation
(2022-05-03)
By adding a frequency increment to the carrier
frequency of the pulses transmitted from an antenna array, it
becomes possible to make the beam dependent on both frequency
and range. This is called a frequency diverse ...
