Study of declination methods while forming the appearance of the surface-to-air unmanned aerial vehicle with a vertical start

open access: yesНаучный вестник МГТУ ГА, 2021
The problem of choosing a rational declination system from alternative variants at the stage of forming the appearance of an unmanned aerial vehicle (UAV) with a vertical launch is considered.

Paleomagnetism of Phanerozoic Geological Complexes in Tuva

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020
The authors have investigated palaeomagnetically the Ordovician, Upper Devonian and Lower Carboniferous strata in Tuva. In the rocks, postfolding secondary and prefolding magnetization components were isolated.

The Geometer: A New Device for Recording Angles in Visual Surveys

open access: yesNAMMCO Scientific Publications, 2020
The Geometer is a new handheld USB device that facilitates a relatively accurate measurement of the declination to a target with instantaneous recording of this and other data.

No evidence for the use of magnetic declination for migratory navigation in two songbird species

open access: yesPLoS ONE, 2020
Determining the East-West position was a classical problem in human sea navigation until accurate clocks were manufactured and sailors were able to measure the difference between local time and a fixed reference to determine longitude.

Declination as a Metric to Detect Partisan Gerrymandering [PDF]

open access: yesElection Law Journal, 2018
We explore the Declination δ, a new metric intended to detect partisan gerrymandering. We show that when vote share is fixed, δ = 0 allows for a wide array of possible seat shares, even when turnout in each district is equal. In particular, if δ = 0, the

Characterization of Machined Surface Topography Based on the Normal Declination Angle of Microfacets

open access: yesMicromachines, 2021
It is important to characterize surface topography in order to study machined surface characteristics. Due to the features of periodicity and randomness of machined surface topography, the existing topographical parameters may not describe its features ...

Search for astrophysical sources of neutrinos using cascade events in IceCube [PDF]

open access: yes, 2017
The IceCube neutrino observatory has established the existence of a flux of high-energy astrophysical neutrinos inconsistent with the expectation from atmospheric backgrounds at a significance greater than $5\sigma$.

Design and research of single‐sided slotted waveguide antenna with a large beam declination

open access: yesIET Microwaves, Antennas & Propagation, 2021
The slot of the conventional longitudinal slot antenna is alternately opened on both sides of the broadside. A novel single‐sided slot array with a large‐declination (biased towards the load) is proposed, in which the slots are only biased to the same ...

Geomagnetic measurements in Latvia

open access: yesGeodesy and Cartography, 2012
The knowledge of the Earth's magnetic field elements and their dynamic fluctuations over the area concerned are important and can be used for many practical purposes in various fields, including Geodesy and Cartography. Earth's magnetic field tends to
