TL;DR: This paper describes the design of a microcomputer-based intelligent under/over-frequency relay, that can adjust the setting points and time delays dynamically, to give a power system a better opportunity to survive an emergency operating condition.
Abstract: According to statistical records, there will be a major system blackout about every ten years. Some of them were because of improper operating of load shedding relays [1]. In order to have a more reliable system, utility engineers should adjust their load shedding relay setting points continually to satisfy the system condition. Unfortunately, they have neither intelligent relays nor convenient means to change the relay settings. As a result, most utilities use a set of frequency settings many years without updating it. This paper describes the design of a microcomputer-based intelligent under/over-frequency relay, that can adjust the setting points and time delays dynamically. This will give a power system a better opportunity to survive an emergency operating condition.

TL;DR: In this article, the authors present an overview of the technical revolution in operations at rural electric utilities and examine off-the-shelf technology that could be applied to operations for the purpose of loss reduction, real-time analysis, automated trouble call processing, and automated mapping/facilities management.
Abstract: The author presents an overview of the technical revolution in operations at rural electric utilities. He begins with a review of the major responsibilities of operations, including power delivery, losses, restoration of power, and planned outages. Next, he reviews incentives that are fueling the revolution, i.e., economics, complexity of loads, quality of service, retiring databanks, conservation, and blackout/brownout. The author examines off-the-shelf technology that could be applied to operations for the purpose of loss reduction, real-time analysis, automated trouble call processing, and automated mapping/facilities management. >

TL;DR: Anterograde amnesia refers to the inability to form new memories in patients with acute transient memory loss.
Abstract: Anterograde amnesia refers to the inability to form new memories. Alcoholic blackout, benzodiazepine-induced amnesia and transient global amnesia are three disorders that result in acute transient memory loss. These disorders may be difficult to recognize, because the memory loss is not usually accompanied by other symptoms of neurologic impairment.

TL;DR: The Palapa B1 satellite veered off its orbital path and caused a complete blackout of communication and television services to two-thirds of the country for three days in 1985 as discussed by the authors.
Abstract: In August 1985, Indonesia’s Palapa B1 satellite veered off its orbital path and caused a complete blackout of communication and television services to two-thirds of the country for three days. Despite such disruptions the Indonesian Government has no intention of replacing the system with other alternatives. This paper examines why this complex and high-risk system was chosen and what its advantages and benefits are.
