Red Flag (signal)
The term ''red flag'' could mean either a literal flag used for signaling or, as a metaphor, a sign of some particular problem requiring attention. Background The term and the expression "to raise the red flag" come from various usages of real flags throughout history. A red flag is frequently flown by armed forces to warn the public of live fire exercises in progress, and is sometimes flown by ships carrying munitions (in this context it is actually the flag for the letter B in the international maritime signal flag alphabet, a red swallow-tailed flag). In many countries a red flag is flown to signify that an outdoor shooting range is in use. The United States Air Force refers to its largest annual exercise as Red Flag operation. Red flags are used for various signals in team sailing races (see Racing Rules of Sailing). A red flag warning is a signal of high wildfire danger, and a red flag on the beach warns of dangerous water conditions (double red flags indicate beach c ...

Red Flag F1
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the ...

Racing Rules Of Sailing
The Racing Rules of Sailing (often abbreviated to RRS) govern the conduct of yacht racing, windsurfing, kitesurfing, model boat racing, dinghy racing and virtually any other form of racing around a course with more than one vessel while powered by the wind. A new revision is published every four years (after the Olympic Games) by World Sailing, the sport's world governing body. Full information on the rules can be viewed at World Sailing. Contents of the Rules Racing Rules of Sailing were most dramatically simplified in 1997 since the 1940s. The new document contains four main rules art 2, Section A # Boats on a port tack shall keep clear of boats on starboard tack (Rule 10). # When boats are on the same tack and overlapped, the boat to windward (the boat closest to the wind) shall keep clear of a leeward boat (Rule 11). # When boats are on the same tack and not overlapped, the boat that is astern shall keep clear of the boat ahead. (Rule 12). # When a boat is tacking (chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Flags Rule
The Red Flags Rule was created by the Federal Trade Commission (FTC), along with other government agencies such as the National Credit Union Administration (NCUA), to help prevent identity theft. The rule was passed in January 2008, and was to be in place by November 1, 2008. But due to push-backs by opposition, the FTC delayed enforcement until December 31, 2010. In December 2010, the Red Flags Rule was clarified by the Red Flag Program Clarification Act of 2010 to exclude most doctors, lawyers, and other professionals who do not receive full payment at the time when their service is furnished. History The Red Flags Rule was based on section 114 and 315 of the Fair and Accurate Credit Transactions Act The Fair and Accurate Credit Transactions Act of 2003 (FACT Act or FACTA, ) is a United States federal law, passed by the United States Congress on November 22, 2003, and signed by President George W.

Racing Flags
Racing flags are traditionally used in auto racing and similar motorsports to indicate track condition and to communicate important messages to drivers. Typically, the starter, sometimes the grand marshal of a race, waves the flags atop a flag stand near the start/finish line. Track marshals are also stationed at observation posts along the race track in order to communicate both local and course-wide conditions to drivers. Alternatively, some race tracks employ lights to supplement the primary flag at the start/finish line. Summary While there is no universal system of racing flags across all of motorsports, most series have standardized them, with some flags carrying over between series. For example, the chequered flag is commonly used across all of motorsport to signify the end of a session (practice, qualifying, or race), while the penalty flags differ from series to series. FIA-sanctioned championship flags are the most commonly used internationally (outside of North Amer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spam Filter
Email filtering is the processing of email to organize it according to specified criteria. The term can apply to the intervention of human intelligence, but most often refers to the automatic processing of messages at an SMTP server, possibly applying anti-spam techniques. Filtering can be applied to incoming emails as well as to outgoing ones. Depending on the calling environment, email filtering software can reject an item at the initial SMTP connection stage or pass it through unchanged for delivery to the user's mailbox. It is also possible to redirect the message for delivery elsewhere, quarantine it for further checking, modify it or 'tag' it in any other way. Motivation Common uses for mail filters include organizing incoming email and removal of spam and computer viruses. Mailbox providers filter outgoing email to promptly react to spam surges that may result from compromised accounts. A less common use is to inspect outgoing email at some companies to ensure that emplo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Alamo
The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna reclaimed the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States), killing most of the occupants inside. Santa Anna's refusal to take prisoners during the battle inspired many Texians and Tejanos to join the Texian Army. Motivated by a desire for revenge, as well as their written desire to preserve a border open to immigration and the importation and practice of slavery, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the rebellion in favor of the newly formed Republic of Texas. Several months previously, Texians, who were primarily recent immigrants from USA, had killed or driven all Mexican troops out of Mexican Texas. About 100 Texians were then garrisoned at the Alamo. The Texian force grew sl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonio López De Santa Anna
Antonio de Padua María Severino López de Santa Anna y Pérez de Lebrón (; 21 February 1794 – 21 June 1876),Callcott, Wilfred H., "Santa Anna, Antonio Lopez De,''Handbook of Texas Online'' Retrieved 18 April 2017. usually known as Santa Anna or López de Santa Anna, was a Mexican politician and general. His influence on post-independence Mexican politics and government in the first half of the nineteenth century is such that historians of Mexico often refer to it as the "Age of Santa Anna". He has been called "the Man of Destiny", "a quintessential ''caudillo'' trongman. Although initially in the post-independence period he identified as a federalist and participated in a coup that ousted the conservatives in 1833, he became increasingly conservative. Elected President in 1833, López de Santa Anna declined to serve and retired to his home state and power base of Veracruz, a pattern that was to repeat itself until his ouster in 1855. López de Santa Anna's military and poli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Risk
In simple terms, risk is the possibility of something bad happening. Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences. Many different definitions have been proposed. The international standard definition of risk for common understanding in different applications is “effect of uncertainty on objectives”. The understanding of risk, the methods of assessment and management, the descriptions of risk and even the definitions of risk differ in different practice areas (business, economics, environment, finance, information technology, health, insurance, safety, security etc). This article provides links to more detailed articles on these areas. The international standard for risk management, ISO 31000, provides principles and generic guidelines on managing risks faced by organizations. Definitions ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Red Flag Warning
A red flag warning is a forecast warning issued by the National Weather Service in the United States to inform the public, firefighters, and land management agencies that conditions are ideal for wildland fire combustion, and rapid spread. After drought conditions, when humidity is very low, and especially when there are high or erratic winds which may include lightning as a factor, the Red Flag Warning becomes a critical statement for firefighting agencies. These agencies often alter their staffing and equipment resources dramatically to accommodate the forecast risk. To the public, a Red Flag Warning means high fire danger with increased probability of a quickly spreading vegetation fire in the area within 24 hours. The weather criteria for fire weather watches and red flag warnings vary with each Weather Service office’s warning area based on the local vegetation type, topography, and distance from major water sources. They usually include the daily vegetation moisture cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Flag (USAF)
Exercise Red Flag (also Red Flag – Nellis) is a two-week advanced aerial combat training exercise held several times a year by the United States Air Force. It aims to offer realistic air-combat training for military pilots and other flight crew members from the United States and allied countries. Each year, four to six Red Flag exercises are held at Nellis Air Force Base, Nevada, while up to four more, dubbed Red Flag – Alaska, are held at Eielson Air Force Base, Alaska. First held on 29 November 1975, Red Flag exercises bring together aircrews from the United States Air Force (USAF), United States Navy (USN), United States Marine Corps (USMC), United States Army (USA) and numerous NATO and allied nations' air forces. Red Flag exercises are conducted under the control of the United States Air Force Warfare Center (USAFWC) at Nellis. They are run by the 414th Combat Training Squadron (414 CTS) of the 57th Wing (57 WG). They use "enemy" hardware and live ammunition for b ...
