Nonlinear Stability Analysis of Area-Preserving Integrators

SIAM Journal on Numerical Analysis, 2000
Linear stability analysis is inadequate for integrators designed for nondissipative systems such as Hamiltonian systems in which nonlinear effects are often decisive. Mathematical theory exists (KAM theory) for rigorous analysis of small perturbations from equilibria, but it needs to be expressed in a form that is more easily applicable to the study of

Visual closed-loop tracking with area stabilization

Proceedings of the 2010 American Control Conference, 2010
We present a technique that combines image segmentation with nonlinear control to achieve closed-loop visual tracking. Camera rotation and zoom are used as the controls. The approach uses an analysis of admissible curve evolution flows generated by changes in projective scaling and angular velocity.

A policymaker’s guide to a Euro area stabilization fund

Economia Politica, 2016
In 2012, several reports were published advocating the creation of a genuine fiscal capacity at the European level, to strengthen the foundations of the Economic and Monetary Union (EMU) by helping member countries to adjust to asymmetric shocks. The design of a common stabilization fund should be well thought, though: what would be stabilized?

The accessible surface area and stability of oligomeric proteins

Nature, 1987
Protein structures are stabilized by hydrophobic and van der Waals forces, and by hydrogen bonds. The relation between these thermodynamic quantities and the actual three-dimensional structure of proteins can not be calculated precisely. However, certain empirical relations have been discovered.

Restoring Financial Stability in the Euro Area

SSRN Electronic Journal, 2011
The pricing of sovereign credit risk is a necessary component of the financial architecture of the European Monetary Union. However, unnecessarily high and volatile risk premia on government bonds are currently preventing effective financial intermediation within the euro area, thereby inhibiting its economic recovery.

Surface area stability of aluminas

Journal of Catalysis, 1990
Abstract Measurements were made of the surface area of aluminas steamed for various times up to 1000 h, at constant temperature and water partial pressure. The data were fitted to the integrated form of the equation −dS/dt = kSn, as a smoothing operation; this accounts for the strong effect of area on the rate of area loss.

Stability Analysis of Landfills in Seismic Area

Geo-Congress 2013, 2013
T he design of landfills includes stability analyses based on appropriate mechanical characterization of soil and Municipal Solid Waste (MSW). Particular attention must be devoted to MSW landfills in seismic areas, where the waste fill and liners can be damaged by the seismic loading, as documented by recent earthquakes.

Stabilization of broad area semiconductor lasers

SPIE Proceedings, 2017
Broad Area Semiconductor edge-emitting lasers typically display self-focusing nonlinearity due to the refractive index dependence on the population inversion. It induces the homogeneous solution instability, multi-transverse mode operation and filamentation.

Operation of Stabilization Ponds in a Tropical Area

1974
Abstract : This study's objective is to provide operating parameters for design of stabilization ponds in tropic areas. Such ponds have the potential to provide a relatively easy to prepare, simple to operate and maintain, method of partial secondary wastewater treatment at low cost.

Area-preserving diffeomorphisms and the stability of the atmosphere

Classical and Quantum Gravity, 1990
It is shown that Arnol'd's estimate for the maximum period of weather predictability is altered if a sphere is used for the Earth's surface rather than a torus.
