Araracuara Airport
Araracuara Airport is an airport serving Araracuara, Colombia, Araracuara, in the Caquetá Department of Colombia. Araracuara was the site of a former penal colony for Colombia's worst and most dangerous criminals. The town and airport are on the north bank of the Caquetá River, an eventual tributary of the Amazon River. The Araracuara non-directional beacon (Ident: ARA) is located just south of the airport.

Contrast Ratio
The contrast ratio (CR) is a property of a display system, defined as the ratio of the luminance of the brightest shade (white) to that of the darkest shade (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display. It has similarities with dynamic range. There is no official, standardized way to measure contrast ratio for a system or its parts, nor is there a standard for defining "Contrast Ratio" that is accepted by any standards organization so ratings provided by different manufacturers of display devices are not necessarily comparable to each other due to differences in method of measurement, operation, and unstated variables. Manufacturers have traditionally favored measurement methods that isolate the device from the system, whereas other designers have more often taken the effect of the room into account. An ideal room would absorb all the light reflecting from a projection screen or emitted by a cathode-ray tube, and the on ...

List Of Cruisers Of The United States Navy
This list of cruisers of the United States Navy includes all ships that were ever called "cruiser", either publicly or in internal documentation. The Navy has 9 cruisers in active service, as of 10 October 2024, with the last tentatively scheduled for decommissioning in 2029. With the cancellation of the CG(X) program in 2010, the Navy currently has no cruiser replacement program planned.Defense News The Navy is looking to the Aegis Combat System, Aegis-equipped destroyers to increasingly fill the role of the cruiser in the protection of the carrier strike group, as it could be well into the 2030s before any possible cruiser replacement program is up and running. Ship status is indicated as either currently active [A] (in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steyr ACR
The Steyr ACR was a prototype flechette-firing assault rifle built for the US Army's Advanced Combat Rifle program of 1989/90. Although the Steyr Steyr (; ) is a statutory city (Austria), statutory city, located in the Austrian federal state of Upper Austria. It is the administrative capital, though not part of Steyr-Land District. Steyr is Austria's 12th most populated town and the 3rd lar ... design proved effective, as did most of the weapons submitted, the entire ACR program ended with none of the entrants achieving performance 100% better than the M16A2, the baseline for a successful ACR weapon. Design The Steyr ACR has some superficial resemblance to the Steyr AUG, although it is rounder and the barrel is covered for almost its entire length, as opposed to the AUG where much of the barrel was exposed. Like the AUG, the ACR is a bullpup design with the 24-round magazine located quite close to the buttstock of the gun. The stock was "split" from the magazine forward to a ...

Armored Cavalry Regiment
An armored cavalry regiment (ACR) is a regiment of the United States Army (Active Component, or Reserve Component (Army Reserve or Army National Guard)) organized for the specific purposes of reconnaissance, surveillance, and security. The regiments can be equipped with Cavalry Fighting Vehicles, tanks and Military helicopter, helicopters. The light armored cavalry regiment was developed in the United States Army in the first years of the Cold War to replace the mechanized cavalry groups used during World War II. The new regiments primarily tasked with providing reconnaissance and security capabilities at the corps level, although also able to attack and defend either mounted or dismounted. The structure of each regiment included a Headquarters and headquarters company (United States), headquarters and headquarters company and three reconnaissance battalions, each of which included a headquarters and service company, three reconnaissance companies, and a medium tank company. 1 ...

Advanced Combat Rifle
The Advanced Combat Rifle (ACR) was a United States Army program, started in 1986, to find a replacement for the M16 assault rifle. Under the stress of battle the average soldier with an M16 may shoot a target at 45 meters, but hit probability is reduced to one out of ten shots on target by 220 meters. Because of this, the ACR program was initiated in the late 1980s to create a weapon that could double the hit probability. None of the weapons tested met the criteria, and the program ended in 1990 after an expenditure of approximately US$300 million. The ACR program was preceded by older programs such as the Special Purpose Individual Weapon. Phase I and II Phase I of the program started in February 1986 when development contracts were placed with six companies: AAI Corporation, Ares Incorporated, Colt's Manufacturing Company, Heckler & Koch (H&K), McDonnell Douglas Helicopter Systems (MDHS), and Steyr Mannlicher. Two weapons were cut from the list before Phase II started. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adaptive Combat Rifle
The Adaptive Combat Rifle (ACR) (known initially as the Masada) is a modular assault rifle designed by Magpul Industries of Austin, Texas. In late January 2008, Bushmaster Firearms International entered into a licensing agreement with Magpul whereby Bushmaster would take over production, future development, and sales of the Masada. It was then known as the Bushmaster ACR. However, Remington Arms is contracted to manufacture the rifle for the US military and US law enforcement agencies, in which it is known as the Remington ACR. Hence, Remington Arms is responsible for the selective-fire version of the ACR, while Bushmaster Firearms International is responsible for the semi-automatic only version. The Remington ACR was one of the weapons displayed to U.S. Army officials during an invitation-only Industry Day on November 13, 2008. The goal of the Industry Day was to review current carbine technology prior to writing formal requirements for a future replacement for the M4 Carbin ...

Copper Tubing
Copper tubing is available in two basic types of tube—plumbing tube and air conditioning/refrigeration (ACR) tube, and in both drawn (hard) and annealed (soft) tempers. Because of its high level of corrosion resistance, it is used for water distribution systems, oil fuel transfer lines, non-flammable medical-gas systems, and as a refrigerant line in HVAC systems. Copper tubing is joined using flare connection, compression connection, pressed connection, or solder. Types Soft copper Soft (or ductile) copper tubing can be bent easily to travel around obstacles in the path of the tubing. While the work hardening of the drawing process used to size the tubing makes the copper hard or rigid, it is carefully annealed to make it soft again; it is, therefore, more expensive to produce than non-annealed, rigid copper tubing. It can be joined by any of the three methods used for rigid copper, and it is the only type of copper tubing suitable for flare connections. Soft copper is the m ...

Automatic Content Recognition
Automatic content recognition (ACR) is a technology used to identify content played on a media device or presented within a media file. Devices with ACR can allow for the collection of content consumption information automatically at the screen or speaker level itself, without any user-based input or search efforts. This information may be collected for purposes such as personalized advertising, content recommendations, or sale to companies that aggregate customer data. How it works To start the process, a short media clip (audio, video, or both) is selected from within a media file or captured as displayed on a device such as a smart TV. Using techniques such as fingerprinting and watermarking, the selected content is compared by the ACR software with a database of known recorded works. If the fingerprint of the media clip finds a match, the ACR software returns the corresponding metadata regarding the media as well as other associated or recommended content back to the client a ...
