Complex numerical modeling of dynamics and crashes of wing-in-ground vehicles [PDF]
, 1993 The Wing-In-Ground craft (WIG), a vehicle flying in the ground effect, is a promising transportation means of the near future. This paper describes mathematical modeling of WIG motion in all regimes, such as planing, take-off, transition to flight ...

All-Optical Broadband Excitation of the Motional State of Trapped Ions
, 2012 We have developed a novel all-optical broadband scheme for exciting, amplifying and measuring the secular motion of ions in a radio frequency trap. Oscillation induced by optical excitation has been coherently amplified to precisely control and measure ...

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation
Advanced Engineering Materials, EarlyView.This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

Effects of visual and motion simulation cueing systems on pilot performance during takeoffs with engine failures [PDF]
Data are presented that show the effects of visual and motion during cueing on pilot performance during takeoffs with engine failures. Four groups of USAF pilots flew a simulated KC-135 using four different cueing systems. The most basic of these systems

Numerical simulation of flow past a cylinder in orbital motion [PDF]
, 2004 A finite difference solution is presented for 2D laminar unsteady flow around a circular cylinder in orbital motion placed in a uniform flow for Re = 130, 160, and 180. Four cases displaying full lock-in are presented.

Inertia and chiral edge modes of a skyrmion magnetic bubble
, 2012 The dynamics of a vortex in a thin-film ferromagnet resembles the motion of a charged massless particle in a uniform magnetic field. Similar dynamics is expected for other magnetic textures with a nonzero skyrmion number.

Advanced Engineering Materials, EarlyView.This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Measures of pilot performance during V/TOL aircraft landings on ships at sea [PDF]
Simulation experiments to determine the feasibility of landing V/TOL aircraft on ships at sea were studied. The motion and attitude of the aircraft relative to the landing platform was known at the instant of touchdown.
