Doctor (title)
Doctor is an Academic degree, academic title that originates from the Latin word of the same spelling and meaning. The word is originally an Agent noun, agentive noun of the Latin verb 'to teach'. It has been used as an academic title in Europe since the 13th century, when the first doctorates were awarded at the University of Bologna and the University of Paris. Having become established in European universities, this usage spread around the world. Contracted "Dr" or "Dr.", it is used as a designation for a person who has obtained a doctorate (commonly a Doctor of Philosophy, PhD). In past usage, the term could be applied to any learned person. In many parts of the world today it is also used by medical practitioners, regardless of whether they hold a doctoral-level Academic degree, degree. Origins The doctorate () appeared in Middle Ages, medieval Europe as a license to teach (licentia docendi) at a medieval university. The roots of the term doctor can be traced to the ...

Debits And Credits
Debits and credits in double-entry bookkeeping are entries made in account ledgers to record changes in value resulting from business transactions. A debit entry in an account represents a transfer of value ''to'' that account, and a credit entry represents a transfer ''from'' the account. Each transaction transfers value from credited accounts to debited accounts. For example, a tenant who writes a rent cheque to a landlord would enter a credit for the bank account on which the cheque is drawn, and a debit in a rent expense account. Similarly, the landlord would enter a credit in the rent income account associated with the tenant and a debit for the bank account where the cheque is deposited. Debits typically increase the value of assets and expense accounts and reduce the value of liabilities, equity, and revenue accounts. Conversely, credits typically increase the value of liability, equity, and revenue account and reduce the value of asset and expense accounts. Debit ...

IT Disaster Recovery
IT disaster recovery (also, simply disaster recovery (DR)) is the process of maintaining or reestablishing vital infrastructure and systems following a natural or human-induced disaster, such as a storm or battle. DR employs policies, tools, and procedures with a focus on IT systems supporting critical business functions. This involves keeping all essential aspects of a business functioning despite significant disruptive events; it can therefore be considered a subset of business continuity (BC). DR assumes that the primary site is not immediately recoverable and restores data and services to a secondary site. IT service continuity IT service continuity (ITSC) is a subset of BCP, which relies on the metrics (frequently used as key risk indicators) of recovery point/time objectives. It encompasses IT disaster recovery planning and the wider IT resilience planning. It also incorporates IT infrastructure and services related to communications, such as telephony and data communi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Radiography
Digital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also, less radiation can be used to produce an image of similar Contrast (vision), contrast to conventional radiography. Instead of X-ray film, digital radiography uses a digital image capture device. This gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving for over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display quality of the image.

Open Shortest Path First
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single Autonomous system (Internet), autonomous system (AS). OSPF gathers link state information from available routers and constructs a topology map of the network. The topology is presented as a routing table to the internet layer for routing packets by their destination IP address. OSPF supports Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) networks and is widely used in large enterprise networks. IS-IS, another LSR-based protocol, is more common in large Network service provider, service provider networks. Originally designed in the 1980s, OSPF version 2 is defined in RFC 2328 (1998). The updates for IPv6 are specified as OSPF version 3 in RFC 5340 (2008). OSPF supports the Classless Inter-Domain Routing (CIDR) addressing model. ...

Design Rationale
A design rationale is an explicit documentation of the reasons behind decisions made when designing a system or artifact. As initially developed by W.R. Kunz and Horst Rittel, design rationale seeks to provide argumentation-based structure to the political, collaborative process of addressing wicked problems. Overview A design rationale is the explicit listing of decisions made during a design process, and the reasons why those decisions were made.Jarczyk, Alex P.; Löffler, Peter; Shipman III, Frank M. (1992), "Design Rationale for Software Engineering: A Survey", ''25th Hawaii International Conference on System Sciences'', 2, pp. 577-586 Its primary goal is to support designers by providing a means to record and communicate the argumentation and reasoning behind the design process.Horner, J.; Atwood, M.E. (2006), "Effective Design Rationale: Understanding the Barriers", in Dutoit, A.H.; McCall, R.; Mistrík, I. et al., Rationale Management in Software Engineering, Spr ...

Demand Response
Demand response is a change in the power consumption of an electric utility customer to better match the demand for power with the supply. Until the 21st century decrease in the cost of pumped storage and batteries, electric energy could not be easily stored, so utilities have traditionally matched demand and supply by throttling the production rate of their power plants, taking generating units on or off line, or importing power from other utilities. There are limits to what can be achieved on the supply side, because some generating units can take a long time to come up to full power, some units may be very expensive to operate, and demand can at times be greater than the capacity of all the available power plants put together. Demand response, a type of energy demand management, seeks to adjust in Real-time computing, real-time the demand for power instead of adjusting the supply. Utilities may signal demand requests to their customers in a variety of ways, including simple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dead Reckoning
In navigation, dead reckoning is the process of calculating the current position of a moving object by using a previously determined position, or fix, and incorporating estimates of speed, heading (or direction or course), and elapsed time. The corresponding term in biology, to describe the processes by which animals update their estimates of position or heading, is path integration. Advances in navigational aids that give accurate information on position, in particular satellite navigation using the Global Positioning System, have made simple dead reckoning by humans obsolete for most purposes. However, inertial navigation systems, which provide very accurate directional information, use dead reckoning and are very widely applied. Etymology Contrary to myth, the term "dead reckoning" was not originally used to abbreviate "deduced reckoning", nor is it a misspelling of the term "ded reckoning". The use of "ded" or "deduced reckoning" is not known to have appeared earlier th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
