Controlled islanding is the last countermeasure for a bulk power system when it suffers from severe cascading contingencies. The objective of controlled islanding is to maintain the stability of each island and to keep the total loss of loads of the whole system to a minimum. This paper presents a novel integrated wide-area measurement systems (WAMS)-based adaptive controlled islanding strategy...

This paper presents: (i) an operational semantics, based on a functional framework, for a concurrent and distributed extension of the Scheme programming language, (ii) a coherency protocol taking care of shared mutable objects, (iii) a new coherency protocol to imperatively control hierarchical groups of cooperating tasks. These two protocols do not require broadcast, nor FIFO communications, n...

Plaids are ambiguous stimuli that can be perceived either as a coherent pattern moving rigidly or as two gratings sliding over each other. Here we report a new factor that affects the relative strength of coherency versus transparency: the global direction of motion of the plaid. Plaids moving in oblique directions are perceived as sliding more frequently than plaids moving in cardinal directio...

We demonstrate the use of a binary diffractive optical element in a very simple setup to convert the multilobed beam from a low fill factor array of coherent laser diodes into a quasi-Gaussian beam. The phase profile of the grating is determined with a phase retrieval algorithm. Experimentally, the conversion efficiency reaches more than 44%. We also establish that this setup can be used to mak...

human milk contains all of the constituents that are required for the optimal growth and development of a neonate. it supports the development of brain, immune, and physiological systems. this study aimed to consider the significance of breast milk in preventing oxidative stress by comparing total antioxidant capacity (tac) in breast and formula milk for premature infants, demonstrating the rel...

Traditional lightning detection and location networks use the time of arrival (TOA) technique to locate events with a single stamp. This contribution introduces simulation study lay foundation for new concepts. Here, novel interferometric method is studied which expands data maps into an area by using coherency. The amplitude waveform bank, consists averaged waveforms classified their propagati...
