-This paper proposes a method to stabilize a power hardware-in-the-loop (PHIL) simulation of inductor coupled systems, in which real time simulator causes instability due to the introduced time delay of the system. The configuration of the PHIL simulation is described and the focused issue is the instability problem of the PHIL simulation. The causes for the instability are analyzed and a solut...

To investigate the effect of instability on the remodelling of a minor articular surface offset, we created a 0.5 mm coronal step-off of the medial femoral condyle in 12 New Zealand white rabbits and transected the anterior cruciate ligament (ACL). A control group of 12 rabbits had only ACL resection and the opposite knee was used as the non-operated control. The osteoarthritic changes at 6, 12...

Consider a network whose inputs change rapidly, or are subject to frequent faults. This is expected often to be the case in the foreseen huge sensor networks. Suppose, that an algorithm is required to output the majority value of the inputs. To address such networks, it is desirable to be able to stabilize the output fast, and to give guarantees on the outputs even before stabilization, even if...

Weak vertical coupled bunch instability with oscillation amplitude at μm level has been observed in SPEAR3. The instability becomes stronger when there is a vacuum pressure rise by partially turning off vacuum pumps and it becomes weaker when the vertical beam emittance is increased by turning off the skew quadrupole magnets. These confirmed that the instability was driven by ions in the vacuum...

Conduction characteristics of amorphous InGaZnO thin-film transistors were investigated by applying constant drain current with gate bias (V GS) modulation. Constant drain current in the off-current (I off) level from the transfer characteristic was applied to the drain electrode and the measured drain voltage with the gate bias sweep. The normalized channel conductance (G d) characteristics we...

Some general properties of the advective-acoustic instability are described and understood using a toy model which is simple enough to allow for analytical estimates of the eigenfrequencies. The essential ingredients of this model, in the unperturbed regime, are a stationary shock and a subsonic region of deceleration. For the sake of analytical simplicity, the 2D unperturbed flow is parallel a...
