The relaxation of two-dimensional rolls in Rayleigh–Bénard convection [PDF]
, 2004 Large aspect ratio, two-dimensional, periodic convection layers containing a Boussinesq fluid of finite Prandtl number bounded by rigid or free horizontal surfaces are investigated numerically.

Optimal Universal Controllers for Roll Stabilization [PDF]
, 2020 Roll stabilization is an important problem of ship motion control. This problem becomes especially difficult if the same set of actuators (e.g. a single rudder) has to be used for roll stabilization and heading control of the vessel, so that the roll ...

, 2021 <p>During the final months of 2011 the New Zealand government revisited a 50 year old proposal to move the inter-island ferry terminal, currently located in Picton, to a site bordering on both Lake Grassmere and the Clifford Bay coastline. This thesis is based around the design of the new terminal facilities.The primary goal of this research is ...

The precision of slow-roll predictions for the CMBR anisotropies [PDF]
, 2000 Inflationary predictions for the anisotropy of the cosmic microwave background radiation (CMBR) are often based on the slow-roll approximation. We study the precision with which the multipole moments of the temperature two-point correlation function can ...

The technique of determining the small angular deviations by an electrostatic sensor
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022 Some methods for determining small angular deviations have been considered on the example of building objects. The design of an electrostatic cylindrical sensor was put forward, and the use of force action of an electric field was proposed in order to ...

Rudder roll stabilization for ships [PDF]
, 1990 This paper describes the design of an autopilot for rudder roll stabilization for ships. This autopilot uses the rudder not only for course keeping but also for reduction of the roll. The system has a series of properties which make the controller design

Roll, roll, roll me away [PDF]
Canadian Medical Association Journal, 2013 When Shelley Stoddart applied for a nursing position with the mobile eye care clinic run by CNIB, there was one job requirement she didn’t understand: the need for an AZ license. So she called her father. “When he heard, he said: ‘You’re going to have to become a truck driver’.”
