Geometric nonlinearities of aircraft systems [PDF]
, 2008 Nonlinearities due to geometric effects, in particular, via angular variables that are not small, are important for aircraft operation. Geometric nonlinearities have a strong effect on the dynamics of the aircraft system under consideration, and they are

Shimmy in a nonlinear model of an aircraft nose landing gear with non-zero rake angle [PDF]
, 2008 This work concentrates on the lateral oscillations in vehicles, also called shimmy, with a particular emphasis on aircraft. A mathematical model of a nose landing gear is discussed with geometric detail that has been mostly neglected in the past research.

Bifurcation Analysis of a Coupled Nose Landing Gear-Fuselage System [PDF]
, 2014 Under certain conditions during takeoff and landing, pilots may sometimes experience vibrations in the cockpit. Because the cockpit is located right above the nose landing gear, which is known to potentially be prone to self-excited vibrations at certain

Artificial Runway Design for Shimmy Testing on Nose Landing Gear [PDF]
, 2023 This report proposes a novel design for general experimentation of shimmy on the nose landing gear of aircraft. Shimmy is known to cause excessive wear on the landing gear, discomfort to occupants, and potential safety hazards.

Stability analysis of nose gear shimmy with nonlinear characteristics of damper [PDF]
, 2023 The shimmy of the front landing gear of an aircraft usually occurs in the process of taking off or landing,which endangers the stability and maneuverability of the aircraft and is a serious aircraft fault.

Embedding Optimization of Layouts via Distortion Minimization
Computer Graphics Forum, EarlyView.Abstract Given an embedding of a layout in the surface of a target mesh, we consider the problem of optimizing the embedding geometrically. Layout embeddings partition the surface into multiple disk‐like patches, making them particularly useful for parametrization and remeshing tasks, such as quad‐remeshing, since these problems can then be solved on ...

Diabetic Medicine, EarlyView.Abstract Introduction Insulin autoantibodies (IAA) are key predictors of type 1 diabetes, particularly in young children. Micro‐radiobinding assays (RBA) are the gold standard for IAA measurement but have limitations. We assessed whether a luciferase immunoprecipitation system (LIPS) assay improved diabetes risk assessment.

Shimmy model for electric vehicle with independent suspensions [PDF]
, 2017 A 5-degrees-of-freedom shimmy model is established to analyse the dynamic responses of an electric vehicle with independent suspensions. Tyre elasticity is considered by means of Pacejka's magic formula.
