System Integrity Protection Scheme for Enhancing Backup Protection of Transmission Lines
IEEE Systems Journal, 2021Contingencies such as faults, loss of generation or load may produce undesirable relay operations which can lead to cascade tripping causing system catastrophic failure. Thus, security of power system protection is a major concern for utilities. In this article, an approach based on system integrity protection scheme is proposed for enhancing the ...

Protecting and Enhancing American Security
2023Abstract UNCLOS enhances American security in multiple ways. These include enhanced navigational regimes in the territorial sea, through straits and archipelagoes, and full protection of navigational freedom in the 200-mile economic zone and on the high seas.

Protecting and Enhancing American Sovereignty
2023Abstract This chapter describes how the UNCLOS Convention protects and expands American sovereignty. Thus, the Convention creates a new area of United States sovereign rights over natural resources of the seafloor and water column to 200 nautical miles off America’s coasts, and it massively expands the legal continental shelf of the ...

Enhancing SIEM Technology to Protect Critical Infrastructures
2013Coordinated and targeted cyber-attacks on Critical Infrastructures (CIs) and Supervisory Control And Data Acquisition (SCADA) systems are increasing and becoming more sophisticated. Typically, SCADA has been designed without having security in mind, which is indeed approached by reusing solutions to protect solely Information Technology (IT) based ...

Protection and Enhancement of Hearing in Noise
Reviews of Human Factors and Ergonomics, 2006Humans are subjected to noise in many occupational, military, transportation, recreational, and other settings, sometimes with attendant ill effects. Some noises may pose the threat of inducing hearing loss; most noises compromise one's ability to hear signals and other desirable sounds, as well as to communicate via speech. In this chapter, we review

International Journal of Critical Infrastructures, 2011
Argonne National Laboratory in partnership with the US Department of Homeland Security (DHS) has developed a methodology to systematically evaluate the protection posture and vulnerability of critical infrastructure and key resources (CIKR). This vulnerability methodology is part of a larger effort by DHS called the Enhanced Critical Infrastructure ...

Out-of-step protection enhancements
Eighth IEE International Conference on Developments in Power System Protection, 2004Power systems are subjected to a wide range of small or larger disturbances during operating conditions and they are designed to survive disturbances caused by faults, loss of a large generator, or line switching. The power system typically adjusts to these disturbances and continues to operate satisfactorily and within the desired bounds of voltage ...

Reflex-mediated enhancement of airway protective mechanisms
The American Journal of Medicine, 2000The upper esophageal sphincter (UES) and lower esophageal sphincter (LES) comprise the basal mechanisms against entry of gastric content into the aerodigestive tract and the airway. There are, however, other mechanisms referred to here as "response mechanisms" that become activated after certain stimulation, such as distention of the esophagus or ...

Topologically protected sound enhancement
Applied Physics LettersThe pursuit of robust and enhanced acoustic sensing has garnered significant attention across multiple fields of acoustic engineering. Here, we propose a feasible approach to realizing sound energy enhancement along the interface of two topologically distinct materials in an acoustic topological waveguide (ATW) with a gradient gap width.
