DacEasy
DacEasy, Inc., originally Dac Software, Inc., was an American developer and publisher of productivity and accounting software active from 1985 to 2000 and based in Dallas, Texas. They were best known for their namesake DacEasy suite of accounting software for the IBM Personal Computer and IBM PC compatibles. The DacEasy software was launched in April 1985 as the least expensive integrated accounting software package on the market, at under US$50. At the time, all others on the market were at least several hundred US dollars per module. In 1987, the DacEasy company was acquired by Insilco Corporation, a conglomerate based in Connecticut, who kept DacEasy around as an independently run subsidiary. In 1991, Insilco sold DacEasy to Sage Software (later known as the Sage Group) of the United Kingdom. Like Insilco, Sage kept DacEasy around as a subsidiary, until 1999. Sage continued to develop an accounting package with the DacEasy name until 2019. History DacEasy, Inc., was founded as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dota Auto Chess
''Dota Auto Chess'' is a strategy video game mod for the video game ''Dota 2''. Developed by Drodo Studio and released in January 2019, the game features teams of automated ''Dota 2'' heroes fighting battles on a chessboard. The mod had over eight million players by May 2019 and its popularity led to the rapid creation of the auto battler genre. Later in 2019, Drodo Studio developed a standalone version known simply as ''Auto Chess'', while Valve, the developer of ''Dota 2'', developed their own standalone version known as ''Dota Underlords''. Gameplay This elimination style game features elements derived from ''Dota 2''. Up to eight players are assigned to their own chessboard upon which their "home" battles are fought. Each player controls a character called a courier, which tracks the player's health, gold (displayed as the courier's mana), and experience level. At the beginning of every round, an enemy team appears on the player's board (home games) and the player's team a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocar DAC
Rocar DAC was a series of buses and trolleybuses produced by the Autobuzul (later Rocar) company of Bucharest, Romania, between 1979 and 2000. They were available in both standard 12-meter models and articulated, 17-meter models. The first examples to enter service were DAC 117UDs that were made towards the end of 1978 and entered service with the ITB in Bucharest in April 1979. For much of the 1980s and early 1990s, these buses and trolleybuses were the backbone of the urban transportation network of Romania since, throughout the 1980s, public transportation companies were not allowed to import any type of vehicle. The buses were designed and built in a period of severe shortages, the main emphasis being put on economizing material usage and simplicity of the design. Most buses of this type did not have power or assisted steering, and only a small number of buses, built in the early part of the project (1979-1982) employed automatic gearboxes, which were abandoned as soluti ...

DAC (vehicle Manufacturer)
DAC, is a Romanian commercial vehicle brand produced since 1971 in the Brașov area, at Brasov Truck Factory. The brand origin stands in the initialism for Diesel Auto Camion, but same time DAC brand served as a reminder of the Romania’s history, the historic region of Dacia, once the land of the ancient dacian kingdom. Under DAC brand, the company manufactured a variety of vehicles, including trucks, special-purpose vehicles, buses, and trolleybuses, along with advanced engines developed in-house. History Brasov Truck Factory (Întreprinderea Autocamioane Brașov) was established after World War II on the foundation of the old ROMLOC automotive factory built in 1921. In the spirit of the communist days, the industrial plant was named ''Steagul Roșu'' (''The Red Flag''). As of 2000, 750,000 trucks had been produced. DAC trucks share the same construction platforms with the company's other brand - Roman (vehicle manufacturer), Roman - but it was not part of the 1971 venture be ...

DAC (automobile)
The D.A.C. was an automobile manufactured in Detroit, Michigan by the Detroit Air-Cooled Car Company from 1922 to 1923. The car debuted at the Detroit Automobile Show in early 1922, with the company planning on producing 10,000 cars a year. Production never reached these figures. Approximately 25 cars were built in the Detroit factory on Cass Avenue. A new factory was built in 1923, at Wayne, Michigan, where 100 cars were built before the company failed. Both open and closed models were produced. Prices ranged from $1250 for the tourer, to $1700 for the coupe and $1750 for the sedan.

D-acetylcarnitine
Acetyl-L-carnitine, ALCAR or ALC, is an acetylated form of L-carnitine. It is naturally produced by the human body, and it is available as a dietary supplement. Acetylcarnitine is broken down in the blood by plasma esterases to carnitine which is used by the body to transport fatty acids into the mitochondria for breakdown and energy production. Biochemical production and action Carnitine is both a nutrient and made by the body as needed; it serves as a substrate for important reactions in which it accepts and gives up an acyl group. Acetylcarnitine is the most abundant naturally occurring derivative and is formed in the reaction: :acetyl-CoA + carnitine CoA + acetylcarnitine where the acetyl group displaces the hydrogen atom in the central hydroxyl group of carnitine. Coenzyme A (CoA) plays a key role in the Krebs cycle in mitochondria, which is essential for the production of ATP, which powers many reactions in cells; acetyl-CoA is the primary substrate for the Krebs c ...

Pneumatic Cylinder
Pneumatic cylinder, also known as air cylinder, is a mechanical device which uses the power of compressed gas to produce a force in a reciprocating linear motion. Like in a hydraulic cylinder, something forces a piston to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved. Engineers sometimes prefer to use pneumatics because they are quieter, cleaner, and do not require large amounts of space for fluid storage. Because the operating fluid is a gas, leakage from a pneumatic cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement. For example, in the mechanical puppets of the Disney Tiki Room, pneumatics are used to prevent fluid from dripping onto people below the puppets. Operation General Once actuated, compressed air enters into the tube at one end of the piston and imparts force on the piston. Consequently, th ...

Discretionary Access Control
In computer security, discretionary access control (DAC) is a type of access control defined by the Trusted Computer System Evaluation Criteria (TCSEC) as a means of restricting access to objects based on the identity of subjects and/or groups to which they belong. The controls are discretionary in the sense that a subject with a certain access permission is capable of passing that permission (perhaps indirectly) on to any other subject (unless restrained by mandatory access control). Discretionary access control is commonly discussed in contrast to mandatory access control (MAC). Occasionally, a system as a whole is said to have "discretionary" or "purely discretionary" access control when that system lacks mandatory access control. On the other hand, systems can implement both MAC and DAC simultaneously, where DAC refers to one category of access controls that subjects can transfer among each other, and MAC refers to a second category of access controls that imposes constr ...

10 Gigabit Ethernet
10 Gigabit Ethernet (abbreviated 10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10GbE defines only full-duplex point-to-point links which are generally connected by network switches; shared-medium CSMA/CD operation has not been carried over from the previous generations of Ethernet standards so half-duplex operation and repeater hubs do not exist in 10GbE. The first standard for faster 100 Gigabit Ethernet links was approved in 2010. The 10GbE standard encompasses a number of different physical layer (PHY) standards. A networking device, such as a switch or a network interface controller may have different PHY types through pluggable PHY modules, such as those based on SFP+. Like previous versions of Ethernet, 10GbE can use either copper or fiber cabling. Maximum distance over copper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital-to-analog Converter
In electronics, a digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal. An analog-to-digital converter (ADC) performs the reverse function. DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals. These two applications use DACs at opposite ends of the frequency/resolution trade-off. The audio DAC is a low-frequency, high-resolution type while the video DAC is a high-frequency low- to medium-resolution type. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including: resolution, maximum sampling frequency and others. Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has insignificant errors in terms of the application. Due to the complexity ...

Diamond Anvil Cell
A diamond anvil cell (DAC) is a high-pressure device used in geology, engineering, and materials science experiments. It permits the compression of a small (sub- millimeter-sized) piece of material to extreme pressures, typically up to around 100–200 gigapascals, although it is possible to achieve pressures up to 770 gigapascals (7,700,000 bars or 7.7 million atmospheres). The device has been used to recreate the pressure existing deep inside planets to synthesize materials and phases not observed under normal ambient conditions. Notable examples include the non-molecular ice X, polymeric nitrogen and metallic phases of xenon, lonsdaleite, and potentially metallic hydrogen. A DAC consists of two opposing diamonds with a sample compressed between the polished culets (tips). Pressure may be monitored using a reference material whose behavior under pressure is known. Common pressure standards include ruby fluorescence, and various structurally simp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
