A standard operational requirement in power systems is that the voltage magnitudes lie within prespecified bounds. Conventional engineering wisdom suggests that such a tightly-regulated profile, imposed for system design purposes and good operation of the network, should also guarantee a secure system, operating far from static bifurcation instabilities such as voltage collapse. In general howe...

This paper presents an AC Transmission system power flow controlled by injecting a compensating voltage in series with the line and injecting reactive power in shunt with the bus. Static Synchronous Series Compensator (SSSC) and Static Synchronous Compensator (STATCOM) are utilized as a series and shunt compensation, respectively while Unified Power Flow Controller (UPFC) is considered as a shu...

Voltage instability has recently become a challenging problem for many power system operators. This phenomenon has been reported to be responsible for severe low voltage condition leading to majo r blackouts. This paper presents the application of Artificial Immune Systems (AIS) for online voltage stability evaluation that could be used as early warning system to the power system operator so th...

An all-digital True Random Number Generator (TRNG) harvesting entropy from the collapse of 2 edges injected into one even-stage ring is fabricated in 40nm CMOS. A configurable ring and tuning loop provides robustness across a wide range of temperature (-40 to 120°C), voltage (0.6 to 0.9V), process variation, and external attack. The dynamic tuning loop automatically configures the ring to meet ...

In plasma immersion ion implantation (PIII), a high voltage pulsed bias is applied to a substrate to accelerate ions from a surrounding plasma for implantation beneath the surface. This technique is often used to modify the surface properties of materials. For example, the intrinsic stress of thin films can be lowered, resulting in improved adhesion. For conducting samples, the energy of the in...

One of the major impediments to successful recovery of function after a spinal cord injury is thought to be the reaction of the neuronal growth cone to inhibitory influences in the local environment in or around the site of the injury. The growth cones of locus coeruleus neurons studied in vitro collapsed upon contact with an extract of CNS myelin but did not collapse on contact with an extract...
