Differential Graded Algebra
In mathematics, in particular abstract algebra and topology, a differential graded algebra is a graded associative algebra with an added chain complex structure that respects the algebra structure. __TOC__ Definition A differential graded algebra (or DG-algebra for short) ''A'' is a graded algebra equipped with a map d\colon A \to A which has either degree 1 (cochain complex convention) or degree −1 (chain complex convention) that satisfies two conditions: A more succinct way to state the same definition is to say that a DG-algebra is a monoid object in the monoidal category of chain complexes. A DG morphism between DG-algebras is a graded algebra homomorphism which respects the differential ''d''. A differential graded augmented algebra (also called a DGA-algebra, an augmented DG-algebra or simply a DGA) is a DG-algebra equipped with a DG morphism to the ground ring (the terminology is due to Henri Cartan). ''Warning:'' some sources use the term ''DGA'' for a DG-alge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diego Garcia
Diego Garcia is an island of the British Indian Ocean Territory, a disputed overseas territory of the United Kingdom. It is a militarised atoll just south of the equator in the central Indian Ocean, and the largest of the 60 small islands of the Chagos Archipelago. The Portuguese were the first Europeans to find it and it was then settled by the French in the 1790s and transferred to British rule after the Napoleonic Wars. It was one of the "Dependencies" of the British Colony of Mauritius until the Chagos Islands were detached for inclusion in the newly created British Indian Ocean Territory (BIOT) in 1965. In 1966, the population of the island was 924. These people were employed as contract farm workers primarily on copra plantations owned by the Chagos-Agalega company. Although it was common for local plantation managers to allow pensioners and the disabled to remain in the islands and continue to receive housing and rations in exchange for light work, children after the ...

Société Des Designers Graphiques Du Québec
The (SDGQ) is the provincial graphic design association in the Canadian province of Quebec. Its stated aim is to advance the profession of graphic design in Quebec and to help its members develop both professionally and financially. Its activities include professional development, co-organizing the Grafika design awards competition, lobbying, and the DGA certification program. The SDGQ has a reconciliatory role in the debate on graphic design certification in Canada. History The history of the SDGQ can be traced back to 1972 when Quebec graphic designers, Georges Beaupré and Roger Lafortune, formed a committee to found the (SGQ). However, SGQ was not officially founded until 1974 when the new association was incorporated. In 1995 the SGQ replaced the word “” (graphic designers or graphic artists) in its name with “” (graphic designers), changing its name to (SDGQ). On June 14, 2011, during its annual general meeting, the SDGQ officially launched its certification pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Governance Act
The Data Governance Act (DGA) is a legislative proposal of the European Commission that aims to create a framework which will facilitate data-sharing. The proposal was first announced within the 2020 European strategy for data and was officially presented by Margrethe Vestager in 25 November 2020. The DGA covers the data of public bodies, private companies, and citizens. Its main aims are to safely enable the sharing of sensitive data held by public bodies, to regulate data sharing by private actors. On 30November 2021, the EU Parliament and Council reached an agreement on the wording of the DGA. Formal approval by those bodies is still required but that should be procedural. The proposed legislation has been analyzed by independent parties. See also * Data Act (European Union) * General Data Protection Regulation The General Data Protection Regulation (GDPR) is a European Union regulation on data protection and privacy in the EU and the European Economic Area (EEA).

Domain Generation Algorithm
Domain generation algorithms (DGA) are algorithms seen in various families of malware that are used to periodically generate a large number of domain names that can be used as rendezvous points with their command and control servers. The large number of potential rendezvous points makes it difficult for law enforcement to effectively shut down botnets, since infected computers will attempt to contact some of these domain names every day to receive updates or commands. The use of public-key cryptography in malware code makes it unfeasible for law enforcement and other actors to mimic commands from the malware controllers as some worms will automatically reject any updates not signed by the malware controllers. For example, an infected computer could create thousands of domain names such as: ''www..com'' and would attempt to contact a portion of these with the purpose of receiving an update or commands. Embedding the DGA instead of a list of previously-generated (by the command and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Graphics Access
Direct Graphics Access is a plug-in for the X display servers that allows client programs direct access to the frame buffer. Graphics hardware communicates via a chunk of memory called a frame buffer. This is an array of values that represent pixel color values on the screen. Writing the appropriate values into the frame buffer therefore allows a program to ''paint'' areas of the screen. However, as with any shared resource, problems occur when multiple programs attempt to access the same resource, as they tend to write over each other's work. In the X Window System, this is solved by having a central display server that mediates between programs that want to draw on the screen. The display server also used to perform a lot of the drawing work, allowing programs to say ''Draw me a circle of this radius filled with this pattern'' or ''draw this text in this font''. The X server does all this work, freeing programmers from having to write their own drawing code. Another advantag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dissolved Gas Analysis
Dissolved gas analysis (DGA) is an examination of electrical transformer oil contaminants. Insulating materials within electrical equipment liberate gases as they slowly break down over time. The composition and distribution of these dissolved gases are indicators of the effects of deterioration, such as pyrolysis or partial discharge, and the rate of gas generation indicates the severity. DGA is beneficial to a preventive maintenance program. The collection and analysis of gases in an oil-insulated transformer was discussed as early as 1928. , many years of empirical and theoretical study have gone into the analysis of transformer fault gases. DGA usually consists of sampling the oil and sending the sample to a laboratory for analysis. Mobile DGA units can be transported and used on site as well; some units can be directly connected to a transformer. Online monitoring of electrical equipment is an integral part of the smart grid. Oil Large power transformers are filled with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diglycolic Acid
Diglycolic acid is an aliphatic dicarboxylic acid, its acidity is between the one of acetic acid and oxalic acid. It is formed in the oxidation of diethylene glycol in the body and can lead to severe complications with fatal outcome. Preparation Oxidation of diethylene glycol with concentrated nitric acid was described by A. Wurtz in 1861 In parallel, W. Heintz reported the synthesis of diglycolic acid from chloroacetic acid by heating with sodium hydroxide solution. In a version with barium hydroxide solution as an alkaline medium, diglycolic acid is obtained in 68% yield after acidification. The yields of the described reactions are unsatisfactory for use on a technical scale. The single-stage nitric acid process gives even in the presence of an oxidation catalyst ( vanadium(V)oxide) yields of only 58-60%. In a multi-stage process of nitric acid oxidation at 70 °C and multiple crystallization steps, evaporation of the residues and return of the diethylene glycol-c ...

Howard Aircraft Corporation
Howard Aircraft Corporation was a small United States aircraft manufacturer in the 1930s and 1940s. The factory was initially on the south side of Chicago Municipal Airport at 5301 W. 65th Street; during World War II a second plant was opened at DuPage Airport west of Chicago. Early history Designer Ben "Benny" Howard, after his success with smaller aircraft, designed and built the ''Mister Mulligan'', a successful 4-seat cross-country racer that also proved a worthy closed-course mount. While Beechcraft had designed and produced their Staggerwing for the private market, that aircraft was mechanically and structurally complex; Howard instead chose to emulate (on a larger scale) the simpler Monocoupe design. After winning both the Bendix and Thompson trophies in 1935, Howard turned to the formation of the Howard Aircraft Company - later Howard Aircraft Corporation on January 1, 1937, to produce commercial versions of the now-famous DGA cabin monoplanes, each custom-built by Ben Ho ...

Dagaare Language
Dagaare is the language of the Dagaaba people of Ghana, Burkina Faso, and Ivory Coast. It has been described as a dialect continuum that also includes Waale and Birifor. Dagaare language varies in dialect stemming from other family languages including: Dagbane, Waale, Mabia, Gurene, Mampruli, Kusaal, Buli, Niger-Congo, and many other sub languages resulting in around 3 million Dagaare speakers. Throughout the regions of native Dagaare speakers the dialect comes from Northern, Central, Western, and Southern areas referring to the language differently. Burkina Faso refers to Dagaare as Dagara and Birifor to natives in the Republic of Côte d’Ivoire. The native tongue is still universally known as Dagaare. Amongst the different dialects, the standard for Dagaare is derived from the Central region’s dialect. Southern Dagaare (or Waale) also stems from the Dagaare language and is known to be commonly spoken in Wa and Kaleo. ''Ethnologue'' divides Dagaare into three l ...
