It is known (see e.g. Weibull (1995)) that ESS is not robust against multiple mutations. In this article, we introduce robustness against multiple mutations and study some equivalent formulations and consequences.

In this paper we discuss the stability of heterodyne terahertz receivers based on small volume NbN phonon cooled hot electron bolometers HEBs . The stability of these receivers can be broken down in two parts: the intrinsic stability of the HEB mixer and the stability of the local oscillator LO signal injection scheme. Measurements show that the HEB mixer stability is limited by gain fluctuatio...

The response mechanism of an economic model under imposed disturbance is an insightful way of looking at the stability properties of the system being modeled. It should show the quantitative magnitude of fluctuations or movements that are generated by the shock and might also indicate policies that would serve to reduce the severity of the fluctuations. In the case of national models, there has...

The parametric resonance of the axial vibrations of a cantilever pipe conveying harmonically perturbed two-phase flow is investigated using the method of multiple scale perturbation. The nonlinear coupled and uncoupled planar dynamics of the pipe are examined for a scenario when the axial vibration is parametrically excited by the pulsating frequencies of the two phases conveyed by the pipe. Aw...

Improving transient voltage stability is one of the most important issues that must be provided by doubly fed induction generator (DFIG)-based wind farms (WFs) according to the grid code requirement. This paper proposes adjusted DC-link chopper based passive voltage compensator and modified transient voltage controller (MTVC) based active voltage compensator for improving transient voltage stab...

based on the “aggregate demand” theory, monetary policies are designed with the aim of achieving desirable level of macroeconomic goals through affecting the stock of money supplyand income velocity of money. thus, the velocity (v)-as well as money supply - has significant impact, particularly on rate of inflation through expansionary or contractionary monetary policy. to focus on the velocity ...

This research was aimed to determine the effect of different concentrations maltodextrin on antioxidants and stability natural dye powder sappan wood under various pH temperature conditions. study used a completely randomized experimental design with five treatments three replications. The in this were: A (addition 5%), B 10%), C 15%), D 20%), E 25%). Before drying process, added extract that h...

Future’s penetration of more distributed generation will have an effect on the power system’s stability and controllability. In general, wind power as a distributed generator does not have inertial response and does not supply control power. A third characteristic of wind power is that it is not conventionally controlled and its main resource is fluctuating. This paper describes a methodology t...
