  1. Abstraction inversion

    examplefarm Original research date May 2009 In computer programming , abstraction inversion is an anti pattern arising when users of a construct need functions implemented within it but not exposed by its interface. The result is that the users re implement the required functions in terms of the interface, which in its turn uses the internal implementation of the same functions. Possible ill effects are The user of such a re implemented function may seriously underestimate its running costs. The user of the construct is forced to obscure his implementation with complex mechanical details. Many users attempt to solve the same problem, increasing the risk of error. Abstraction inversion in practice Unreferenced section date March 2009 Ways to avoid this anti pattern include For designers of lower level software If your system offers formally equivalent functions, choose carefully which to implement in terms of the other. Do not force unnecessarily weak constructs on your users. For implementers of higher level software Choose your infrastructure carefully.

  1. Water abstraction

    reflist Refimprove date August 2009 Water abstraction , water extraction , or groundwater abstraction is the process of taking water from any source, either temporarily or permanently. Most water is used for irrigation or treatment to produce drinking water . Depending on the environmental legislation in the relevant country, controls may be placed on abstraction to limit the amount of water that can be removed. Over abstraction can lead to river s drying up or the level of groundwater aquifer s reducing unacceptably. The science of hydrogeology is used to assess safe abstraction levels. In some U.S. industries, the terminology for water use describes the removal of water from the environment as water withdrawal , and the conversion of fresh water into water vapor or wastewater as water consumption . ref http www.ucsusa.org clean energy technology and impacts impacts energy and water.html?utm source SP&utm medium more&utm campaign SP more nuke water 4 21 11 ref ref http neinuclearnotes.blogspot.com 2008 03 nei fact sheet on water consumption at.html ref References references Category Hydrology Industry stub ...   more details

    Abstraction of Synchrony is the proposed ability to generically call a Service Operation without regard to whether the target service is configured as a Synchronous or Asynchronous protocol. The user may then call all services and expect a reply which may be utilized generically. This architectural abstraction is made necessary due to Functional logic business logic abstraction , which is the capability of separating business logic implementation code from the service protocol implementation calling it. The fact that business logic implementations operations may be implemented in Synchronous or Asynchronous manners and that these business logic implementations may be interchangeable can cause problems when not addressed.

  1. Hypostatic abstraction

    technical date May 2011 Hypostatic abstraction in mathematical logic , also known as hypostasis or subjectal abstraction , is a formal calculation formal operation that transforms a Predicate mathematical logic predicate into a Relation philosophy relation for example Honey is sweet is transformed into Honey possesses sweetness . The relation is created between the original subject and a new term that represents the Property philosophy property expressed by the original predicate. Hypostasis changes a propositional formula of the form X is Y to another one of the form X has the property of being Y or X has Y ness . The logical functioning of the second subject Y ness consists solely in the truth values of those propositions that have the corresponding concrete term Y as the predicate. The object of thought introduced in this way may be called a hypostatic object . The above definition is adapted from the one given by Charles Sanders Peirce CP 4.235, The Simplest Mathematics 1902 , in Collected Papers , CP 4.227 323 . As Peirce describes it, the main point about the formal operation of hypostatic abstraction, insofar as it operates on formal linguistic expressions, is that it converts an adjective or predicate into an extra subject, thus increasing by one the number of subject slots called the arity or adicity of the main predicate. The transformation of honey is sweet into honey possesses sweetness can be viewed in several ways Image Hypostasis diagram.png 400px The grammatical trace of this hypostatic transformation is a process that extracts the adjective sweet from the predicate ...

  1. Abstraction (linguistics)

    The term abstraction has a number of uses in the field of linguistics . It can denote a process also called object abstraction in the development of language, whereby terms become used for concepts further removed from the objects to which they were originally attached. It can also denote a process applied by linguists themselves, whereby phenomena are considered without the details that are not relevant to the desired level of analysis. Object abstraction Object abstraction, or simply abstraction , is a concept wherein terms for objects become used for more abstract concepts, which in some languages develop into further abstractions such as verbs and grammatical words grammaticalisation . Abstraction is common in human language, though it manifests in different ways for different languages. In language acquisition, children typically learn object words first, and then develop from that vocabulary an understanding of the alternate uses of such words. For example the word book refers objectively to a physical object constructed with bound pages, but in abstraction refers to a particular literary creation &mdash regardless of how many physical copies of the book there are, it is one book. ref Example taken from Chomsky , BBC interview titled Silent Children, New Language ref The word book then developed more abstract uses, such as in keeping a record bookkeeping , or to keep a record of betting booking , or as a verb for entering persons into a record to book .

  1. Predicate abstraction

    In logic , predicate abstraction is the result of creating a Predicate logic predicate from an open sentence . If Q x is any formula with x free then the predicate formed from that sentence is x.Q x , where is an abstraction operator . The resultant predicate x.Q x is a monadic predicate capable of taking a term t as argument as in x.Q x t , which says that the object denoted by t has the property of being such that Q. The law of abstraction states x.Q x t Q t x where Q t x is the result of replacing all free occurrences of x in Q by t. This law is shown to fail in general in at least two cases i when t is irreferential and ii when Q contains modal operator s. In modal logic the de re     de dicto distinction is stated as 1. DE DICTO math Box A t math 2. DE RE math lambda x. Box A x t math . In 1 the modal operator applies to the formula A t and the term t is within the scope of the modal operator. In 2 t is not within the scope of the modal operator.

  1. Abstraction (mathematics)

    Refimprove date April 2010 Abstraction in mathematics is the process of extracting the underlying essence of a mathematical concept, removing any dependence on real world objects with which it might originally have been connected, and generalising it so that it has wider applications or matching among other abstract descriptions of equivalent phenomena . Many areas of mathematics began with the study of real world problems, before the underlying rules and concepts were identified and defined as abstract structure s. For example, geometry has its origins in the calculation of distances and areas in the real world statistics has its origins in the calculation of probabilities in gambling and algebra started with methods of solving problems in arithmetic . Abstraction is an ongoing process in mathematics and the historical development of many mathematical topics exhibits a progression from the concrete to the abstract. Take the historical development of geometry as an example the first steps in the abstraction of geometry were made by the ancient Greeks, with Euclid s Elements being the earliest extant documentation of the axioms of plane geometry though Proclus tells of an earlier axiomatisation by Hippocrates of Chios . ref http www gap.dcs.st and.ac.uk history Extras Proclus history geometry.html Proclus Summary ref In the 17th century Descartes introduced Cartesian co ordinates which allowed the development of analytic geometry .

  1. Payload abstraction

    Payload abstraction is the ability to send a payload the document or request object sent to a Service without regard to what protocol might be configured. This architectural abstraction is made necessary due to Transport protocol abstraction , which is the capability of switching protocols at runtime through the use of a configuration file. The fact that different protocols allow different data types may lead to problems in payload definition. That is, a system must either determine at design time all possible service protocol implementations that might be used by their service for all time, or a payload must be designed with least common denominator data types. For example, a Java based direct call Service Protocol implementation would likely allow any Java type to be sent. A JMS Service Protocol implementation might allow only a subset of these types. An XML RPC Service Protocol implementation might allow an even more limited subset of types. In order to dynamically switch from one protocol to another, the payload design must implement only the simplest types which all protocols will accept without error, or use Payload Abstraction. A description of example implementations of Payload Abstraction, from the elemenope User Guide blockquote Doppelganger extension Doppelganger is an extension to the elemenope Framework which requires an XML schema definition for the payload. This schema is used to dynamically generate Java classes which may be used to marshall data to XML and back. The payload is the generated XML. In this manner, all protocols at least all protocols implemented at this time may pass the marshalled XML without error. The Services and their configured Operation implementations only ever see the objects of the classes generated by Doppelganger. Doppelganger uses ....

  1. Metalinguistic abstraction

    Unreferenced date December 2009 In computer science , metalinguistic abstraction is the process of solving complex problems by creating a new language or vocabulary to better understand the problem space. It is a recurring theme in the seminal Massachusetts Institute of Technology MIT textbook, the Structure and Interpretation of Computer Programs , which uses Scheme programming language Scheme as a framework for constructing new languages. Explanation For example, consider modelling an airport inside a computer. A procedural language procedural e.g. C programming language C programmer would create data structures to represent the elements of an airport and functions to operate on those data structures. An object oriented e.g. C programmer would create object computer science object s to represent the elements of the airport with Method computer science method s which represent their behaviors. A functional programming functional e.g. Scheme programmer would create functions representing both elements and behaviors of the airport. A metalinguistic programmer would abstract the problem by creating a new language for modelling an airport with its own primitives and operations. The language could then encompass any or all of the above techniques as required by the problem at hand. Because the creation of functional metalinguistic abstractions in non functional languages can be cumbersome and also because of the syntactic flexibility of functional Macro computer science macros , metalinguistic programming is most often performed on a functional base.

  1. Abstraction (sociology)

    Unreferenced date October 2007 Sociological Abstraction refers to the varying levels at which theoretical concepts can be understood. This idea is very similar to the philosophical understanding of abstraction . There are two basic levels of sociological abstraction sociological concepts and operationalized sociological concepts. A sociological concept is a mental construct that represents some part of the world in a simplified form. An example of a mental construct is the idea of class, or the distinguishing of two groups based on their income, culture, power, or some other defining characteristic s . Concepts can remain abstract or can be operationalized. Operationalizing a sociological concept takes it to the concrete level by defining how one is going to measure it. Thus, with the concept of class one could operationalize it by actually measuring people s income. Once operationalized, you have a concrete representation of a sociological concept. In addition to the basic levels of sociological abstraction, sociological concepts are often understood at multiple levels as a result of sociological theorizing. Sociological theories postulate relationships between sociological concepts. It is generally understood that there are three levels of sociological theorizing The most abstract level of sociological theory is often referred to as Grand Theory . Grand Theory attempts to explain the inter relationships among numerous concepts and intends to be independent of time and space. In other words, it intends to be universally applicable. An example would be Talcott Parsons Action Systems Theory , which attempted to explain the workings of society at a very abstract level. Another example would be Marx s Historical Materialism , which argued economic relations were the foundation of social structure. Middle range theories are also explanations of human behavior that go beyond one particular observation but are limited in scope and do not attempt to explain all of society.
