Fast transients in mesoscopic systems

AIP Conference Proceedings, 2011
We study fast transient dynamics of an open quantum system at the initial stage of its equilibration starting far from equilibrium from correlated initial conditions reflecting entanglement with the environment. These correlations rapidly decay and the process enters the non‐equilibrium quasi‐particle mode controlled by a generalized master equation ...

Simple fast transient digitizer

Review of Scientific Instruments, 1981
The design and operation of a simple transient digitizer are described, capable of digitizing repetitive analog–transient signals with 30 ns, 8 bit resolution, at repetition rates of at least 300 Hz. The 2 μs maximum transient width (64 samples at 30 ns intervals per transient) can easily be extended.

Fast Transient Stability Solutions

IEEE Transactions on Power Apparatus and Systems, 1972
Techniques are described for improving the speed of large transient stability studies without sacrificing accuracy. A fast iterative method for solving the algebraic network equations, including the effect of generator saliency, is explained. A new technique for solving the differential equations with the implicit trapezoidal rule of integration is ...

Very fast transients in GIS

IEEE Transactions on Power Delivery, 1989
Different types of very fast transients (VFTs) are classified and their characteristic parameters are summarized based on measurements in a 800 kV SF/sub 6/ gas-insulated pilot installation and 420 kV GIS (gas-insulated switchgear) in service. The electromagnetic field between the enclosure and earth results in a transient enclosure voltage of up to ...

Fast Transient Security Assessment

IEEE Power Engineering Review, 1983
The growth of large interconnected power systems demands a high degree of security for normal operation. This requirement emerges from the fact that the possible disturbances in large power systems could have catastrophic results. Therefore it is the duty of power system control center to retain the operating point within secure boundaries. In order to

Transient Lens Spectroscopy in a Fast Timescale

Israel Journal of Chemistry, 1994
AbstractUsing the thermal lens experimental configuration, many types of fast molecular dynamics besides the density variation (the normal thermal lens signal) are reflected by the lens signal. Various transient lens techniques in a fast timescale are reviewed.

Fast-decoupled transient stability

Canadian Journal of Electrical and Computer Engineering, 1989
Presents an improved method for computing transient stability using a fast-decoupled formulation of the transient energy function. The new formulation offers significant savings in computer time as compared to the existing Newton-Raphson formulation.

Detection and modeling of fast attack transients

2001
Attack transients or simply attacks, are zones of short duration and fast variation of the sound signal short-time spectrum such as at the attack of percussion instruments. There are many motivations for attack detection and modeling; improving general analysis techniques is one of them.

Electrically Fast Transient (EFT)

2014
High-frequency transients and impulses such as electrically fast transients (EFT) are caused by light switches, relay chatter, or motor start-up transients on the power line. These transients often occur in bursts and can cause upset to your product if the power line filtering is inadequate.
