Aircraft body-axis rotation measurement system [PDF]
, 1983 A two gyro four gimbal attitude sensing system having gimbal lock avoidance is provided with continuous azimuth information, rather than roll information, relative to the magnetic cardinal headings while in near vertical attitudes to allow recovery from ...

Numerical Analysis of Roll Hydrodynamic Coefficients of 2D Triangular Cylinder Using OpenFOAM
Journal of Marine Science and EngineeringPredicting the roll damping coefficient of a ship is a crucial factor in determining the dynamic stability of the vessel. However, a nonlinear analysis that considers the viscosity of the fluid is required to accurately estimate the roll damping ...

Study on the Steepness of Landslide-Induced Wave and Nonlinear Motion of Container Ships
Applied Sciences, 2020 Large-scale instability of a landslide body, sliding down a bank slope and entering water at a high speed, arouses landslide surges. Taking the water entry point as a source point, they spread rapidly to surrounding areas, increasing the danger risk of ...

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Index on Censorship, 2001 Vladimir Bukovsky was first arrested in 1963 for the possession of anti-Soviet literature and interned in a special psychiatric hospital for 14 months. In 1965, he was rearrested for co-organising a Moscow human rights demonstration in defence of writers Andrei Sinyavsky and Yulii Daniel, and sent to a series of mental hospitals.

CMB quadrupole suppression: II. The early fast roll stage [PDF]
, 2006 Within the effective field theory of inflation, an initialization of the classical dynamics of the inflaton with approximate equipartition between the kinetic and potential energy of the inflaton leads to a brief fast roll stage that precedes the slow ...

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...
