Collecting size-selectivity data for Antarctic krill (Euphausia superba) with a trawl independent towing rig. [PDF]
PLoS ONE, 2018 For the development of efficient trawls to minimize catch loss, escape mortality and potential negative ecosystem impacts from the fishery, the understanding about trawl selectivity processes are crucial.

Influence of Variable Side-Stay Geometry on the Shimmy Dynamics of an Aircraft Dual-Wheel Main Landing Gear [PDF]
, 2013 Commercial aircraft are designed to fly but also need to operate safely and efficiently as vehicles on the ground. During taxiing, take-off, and landing the landing gear must operate reliably over a wide range of forward velocities and vertical loads ...

Enhanced algorithm for gear calculation for justified selection of materials of gears and wheels
Izvestiya MGTU MAMI, 2014 This paper proposes a new improved algorithm for gear calculating allowing justified selection of sizes and heat treatment of the material for manufacture of gears and wheels, considering service life and operational mode. On the basis of the proposed algorithm, a program for gear calculation is developed.

Estimating the selectivity of unpaired trawl data: a case study with a pelagic gear
Scientia Marina, 2016 Most selectivity experiments employ either the covered codend or paired gear methods. It is not always possible, however, to use these methods. Owing to operational, biological and/or environmental considerations, there may be no obvious way or it may be
