Small Sample Confidence Intervals for Multivariate Impulse Response Functions at Long Horizons [PDF]

Existing methods for constructing confidence bands for multivatiate impulse response functions depend on auxiliary assumptions on the order of integration of the variables.

Reactive high power impulse magnetron sputtering

, 2019
Reactive magnetron sputtering is essential in many industrial processes where it is applied to deposit compound films or coatings. Reactive sputtering is attractive because a range of compounds can be prepared from a low-cost metal target by addition of ...

Stochastic impulse control with discounted and ergodic optimization criteria: A comparative study for the control of risky holdings [PDF]

We consider a single-asset investment fund that in the absence of transactions costs would hold a constant amount of wealth in the risky asset. In the presence of market frictions wealth is allowed to fluctuate within a control band: Its upper (lower ...

Impulse Grounding Resistance Reduction Measures for Transmission Line Towers in Desert, Gobi, and Barren Land Regions

Energies
The high soil resistivity in desert, Gobi, and barren land regions limits the lightning current dissipation capability of conventional needle-type grounding electrodes, thereby increasing the lightning-related risk to transmission lines.

High power impulse magnetron sputtering under industrial conditions

, 2011
In this thesis, the recent development step of magnetron sputtering, termed high power impulse magnetron sputtering (HiPIMS) has been studied. Compared to conventional magnetron sputtering HiPIMS provides a higher plasma density which can ionise the sputtered material.

Extreme scenario-based risk assessment of landslide-induced impulse wave from spoil disposal slope instability in hy-dropower projects

Frontiers in Earth Science
In the development of hydropower projects in high-mountain gorge regions, the insta-bility of high-position spoil disposal areas under extreme scenarios and the subsequent disaster chains triggered by landslide-induced impulse waves pose serious threats ...

Physics of high power impulse magnetron sputtering discharges

, 2019
The most striking difference between HiPIMS and other magnetron sputtering discharges, in terms of the plasma process itself, lies in the high-power discharge pulses applied and the large discharge currents generated.
