Stability analysis of static solutions in a Josephson junction

, 2000
We present all the possible solutions of a Josephson junction with bias current and magnetic field with both inline and overlap geometry, and examine their stability. We follow the bifurcation of new solutions as we increase the junction length.

Investigation of propeller slipstream effects on lateral and directional static stability of transport aircraft

Engineering Applications of Computational Fluid Mechanics, 2022
The aerodynamic characteristics of turboprop aircraft are greatly affected by the running propellers. In this paper, propeller slipstream effects on the static lateral-directional stability characteristics of a typical twin-engine turboprop aircraft with

Effect of stand segmentation on growth and development of Norway spruce stands

Journal of Forest Science, 2009
Segmentation of stands by tracks is often the first phase of forest tending. However, a suitable track width is still discussed in forest practice in the Czech Republic.

Method of static stability dominant identification

IET Generation, Transmission & Distribution, 2023
Two extreme cases of static stability are voltage stability and power angle stability. The general stability analysis only focuses on one of the voltage stability or power angle stability.

Vertical stability of circular orbits in relativistic razor-thin disks [PDF]

, 2016
During the last few decades, there has been a growing interest in exact solutions of Einstein equations describing razor-thin disks. Despite the progress in the area, the analytical study of geodesic motion crossing the disk plane in these systems is not

Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters [PDF]

, 2016
This paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference frame phase locked loop (PLL).

Nonlinear perturbations of the Kaluza-Klein monopole

, 2006
We consider the nonlinear stability of the Kaluza-Klein monopole viewed as the static solution of the five dimensional vacuum Einstein equations.

Extended flight evaluation of a near-term pitch active control system [PDF]

Fuel savings can be achieved by moving the center of gravity of an aircraft aft which reduces the static stability margin and consequently the trim drag. However, flying qualities of an aircraft with relaxed static stability can be significantly degraded.

Linearized stability analysis of thin-shell wormholes with a cosmological constant

, 2003
Spherically symmetric thin-shell wormholes in the presence of a cosmological constant are constructed applying the cut-and-paste technique implemented by Visser.

Classical Stabilization of Homogeneous Extra Dimensions [PDF]

, 2001
If spacetime possesses extra dimensions of size and curvature radii much larger than the Planck or string scales, the dynamics of these extra dimensions should be governed by classical general relativity. We argue that in general relativity, it is highly
