Contingency Plan
A contingency plan, or alternate plan, also known colloquially as Plan B, is a plan devised for an outcome other than in the usual (expected) plan. It is often used for risk management for an exceptional risk that, though unlikely, would have catastrophic consequences. Use Contingency plans are often devised by businesses or governments. There are five steps of implementing contingency plan, which are organize a planning team, assess the scope of the problem, develop a plan, test the plan, and keep the plan up-to-date. For example, if many employees of a company are traveling together on an aircraft which crashes, killing all aboard, the company could be severely strained or ruined by such a loss. Therefore, many companies have procedures to follow in the event of such a disaster. The plan may also include standing policies to mitigate a disaster's potential impact, such as requiring employees to travel separately or limiting the number of employees on any one aircraft.

HD Radio
HD Radio (HDR) is a trademark for in-band on-channel (IBOC) digital radio broadcast technology. HD radio generally simulcast, simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by FM broadcasting, FM radio stations in the United States, U.S. Virgin Islands, Canada, Mexico and the Philippines, with a few implementations outside North America. HD Radio transmits the digital signals in unused portions of the same band as the analog AM and FM signals. As a result, radios are more easily designed to pick up both signals, which is why the HD in HD Radio is sometimes referred to stand for "hybrid digital", not "high definition". Officially, HD is not intended to stand for any term in HD Radio, it is simply part of iBiquity's trademark, and does not have any meaning on its own. HD Radios tune into the station's analog signal first and then look for a digital signal. The European DRM system shares c ...

Fallback Font
A fallback font is a reserve typeface containing symbols for as many Unicode characters as possible. When a display system encounters a character that is not part of the repertoire of any of the other available fonts, a symbol from a fallback font is used instead. Typically, a fallback font will contain symbols representative of the various types of Unicode characters. This should not be confused with a Unicode font, which contains a large number of glyphs that actually contain the existing Unicode characters themselves for a large number of characters, such as GNU Unifont. Systems that do not offer a fallback font typically display black or white rectangles, question marks, the Unicode Replacement Character (U+FFFD), or nothing at all, in place of missing characters. Placing one or more fallback fonts at the end of a list of preferred fonts ensures that there are no missing characters. Unicode BMP Fallback font 0 0 2 0 The Unicode BMP Fallback f ...

Fallback Voting
Bucklin voting is a class of voting methods that can be used for single-member and multi-member districts. As in highest median rules like the majority judgment, the Bucklin winner will be one of the candidates with the highest median ranking or rating. It is named after its original promoter, the Georgist politician James W. Bucklin of Grand Junction, Colorado, and is also known as the Grand Junction system. Voting process Bucklin rules varied, but here is a typical example: Voters are allowed rank preference ballots (first, second, third, etc.). First choice votes are first counted. If one candidate has a majority, that candidate wins. Otherwise the second choices are added to the first choices. Again, if a candidate with a majority vote is found, the winner is the candidate with the most votes accumulated. Lower rankings are added as needed. A majority is determined based on the number of valid ballots. Since, after the first round, there may be more votes cast than vot ...

Fast Fallback
Happy Eyeballs (also called Fast Fallback) is an algorithm published by the IETF that makes dual-stack applications (those that understand both IPv4 and IPv6) more responsive to users by attempting to connect using both IPv4 and IPv6 at the same time (preferring IPv6), thus minimizing IPv6 brokenness and DNS whitelisting experienced by users that have imperfect IPv6 connections or setups. The name "happy eyeballs" derives from the term "eyeball" to describe endpoints which represent human Internet end-users, as opposed to servers. Happy Eyeballs is designed to address the problem that many IPv6 networks are unreachable from parts of the Internet, and applications that try to reach those networks appear unresponsive, which frustrates users. Happy Eyeballs solves this problem by determining which transport would be better used for a particular connection by trying them both in parallel. An application that uses a Happy Eyeballs algorithm checks both IPv4 and IPv6 connectivity (with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Withdrawal (military)
A tactical withdrawal or retreating defensive action is a type of military operation, generally meaning that retreating forces draw back while maintaining contact with the enemy. A withdrawal may be undertaken as part of a general retreat, to consolidate forces, to occupy ground that is more easily defended, force the enemy to overextend to secure a decisive victory, or to lead the enemy into an ambush. It is considered a relatively risky operation, requiring discipline to keep from turning into a disorganized rout or at the very least doing severe damage to the military's morale. Tactical withdrawal A withdrawal may be anticipated, as when a defending force is outmatched or on disadvantageous ground, but it must cause as much damage to an enemy as possible. In such a case, the retreating force may use a number of tactics and strategies to further impede the enemy's progress. That could include setting mines or booby traps during or before the withdrawal, leading the enemy in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
