  1. Actor-Based Concurrent Language

    Actor Based Concurrent Language ABCL is a family of programming language s, developed in Japan in the 1980s and 1990s. ABCL 1 ABCL 1 Actor Based Concurrent Language is a prototype based programming prototype based concurrent programming language for the ABCL MIMD system, created in 1986 by Akinori Yonezawa , of the Department of Information Science at the University of Tokyo . ABCL 1 uses asynchronous message passing among object programming objects to achieve concurrency. It requires Common Lisp . Implementations in Kyoto Common Lisp KCL and Symbolics Lisp are available from the author. ABCL R ABCL R is an object oriented reflection computer science reflective subset of ABCL 1, written by Professor Akinori Yonezawa of Tokyo Institute of Technology in 1988. ABCL R2 ABCL R2 is a second generation version of ABCL R, designed for the Hybrid Group Architecture. It was produced at the Tokyo Institute of Technology in 1992, and has almost all the functionality of ABCL 1. It is written in Common Lisp . As a reflective language, its programs can dynamically control their behavior, including scheduling policy, from within a user process context. ABCL c ABCL c is an object oriented concurrent language, a variant of ABCL 1 based on C programming language C instead of Lisp programming language Lisp .

  1. Object-based language

    Unreferenced date August 2009 The term object based language may be used in a technical sense to describe any programming language that uses the idea of encapsulating state and operations inside object computer science objects . Object based languages need not support Inheritance computer science inheritance or Subtype subtyping , but those that do are also said to be object oriented programming object oriented . Object based languages that do not support inheritance or subtyping are usually not considered to be true object oriented languages. Examples of object oriented programming language object oriented languages include Simula , Smalltalk , C whose object model was based on Simula s , Objective C whose object model was based on Smalltalk s , Eiffel programming language Eiffel , Python programming language Python , Ruby programming language Ruby , Java programming language Java , C Sharp programming language C , Visual Basic .NET and REALbasic an object oriented BASIC dialect . An example of a language that is object based but not object oriented is Visual Basic VB . VB supports both objects and classes, but not inheritance, so it does not qualify as object oriented. In practice, the term object based is normally applied only to those object based languages that are not also object oriented. Although all object oriented languages are also object based, by definition, they are not normally referred to as such. Fact date June 2008 Instead the terms object based and object oriented ... other template objects. An example of a commonly used prototype based language is JavaScript .

  1. Task-based language learning

    Task based language learning TBLL , also known as task based language teaching TBLT or task based instruction TBI focuses on the use of authentic language and on asking students to do meaningful tasks using the target language. Such tasks can include visiting a doctor, conducting an interview, or calling customer service for help. Assessment is primarily based on task outcome in other words the appropriate completion of tasks rather than on accuracy of language forms. This makes TBLL especially popular for developing target language fluency and student confidence. TBLL was popularized by N. Prabhu while working in Bangalore, India ref Harmer, Jeremy.

  1. Actor (programming language)

    Refimprove date April 2010 The Actor programming language was invented by Charles Duff of The Whitewater Group in 1988. It was an offshoot of some object oriented extensions to the Forth language he had been working on. Actor would be categorized as a pure object oriented language in the style of Smalltalk . Like Smalltalk, everything was an object, including small integers. A Baker semi space Garbage collection computer science garbage collector was used, along with in memory constrained Windows 2.1 days a software virtual memory system that swapped objects. A token threaded Interpreted language interpreter , written in 16 bit x86 assembly language, was the execution mechanism for compiled code. Actor only was released on the Microsoft Windows 2.1 and 3.0 operating system. Actor used perhaps the first pure object oriented framework over native operating system calls as its basic GUI architecture. This allowed an Actor application to look and feel exactly like a Windows application written in C, but with all the advantages of an interactive Smalltalk like development environment. Both a downside and upside to this architecture was a tight coupling to the Windows OS architecture, with a thin abstraction layer into objects. This allowed direct use of the rich Windows OS API, but also made it nearly impossible to support any other OS without a significant rewrite of the application framework.

    Skill based theories of second language acquisition are theories of second language acquisition theories of second language acquisition based on models of skill acquisition in cognitive psychology . These theories conceive of second language acquisition as being learned in the same way as any other skill, such as learning to drive a car or play the piano. That is, they see practice learning method practice as the key ingredient of language acquisition.

  1. Namespace-based Validation Dispatching Language

    Onesource date March 2009 Namespace based Validation Dispatching Language NVDL is an XML schema language for XML Validation validating XML documents that integrate with multiple XML Namespace namespaces . It is an International Organization for Standardization ISO International Electrotechnical Commission IEC standard, and it is Part 4 of the Document Schema Definition Languages DSDL schema specification. Much of the work on NVDL is based on the older Namespace Routing Language . Validation Most XML languages are based on a single XML namespace. The expectation in these cases is that XML elements in a particular namespace belong to that language, and elements in another namespace belong to another language. Many XML languages allow the use of arbitrary elements from other namespaces. The problem arises during the attempt to validate these hybrid documents. Each language is defined by a specific XML schema, but there is no linkage between the schemas. The purpose of NVDL is to provide that linkage, based on namespaces. By associating a schema validator with an NVDL schema, the validator can use multiple schemas to validate a single document, switching between them based on the namespaces used in that document. Format NVDL documents contain a list of rules, each of which has one or more actions to take when that rule is true. Rules include a specific namespace and a mode setting. NVDL recognizes the mode as a particular piece of state that changes as the document is processed. Actions occur when a rule is true. Actions can include validating a schema, declaring the instance document invalid, accepting this part of the instance document as valid, and continue validating as the parent did. Actions can also change the current NVDL mode. Multiple actions can be taken when a rule ...

  1. Concurrent Pascal

    Unreferenced date February 2007 Concurrent Pascal also known as PASCAL FC was designed by Per Brinch Hansen for writing concurrent computing programs such as operating system s and real time monitoring systems on shared memory computers. A separate language, Sequential Pascal , is used as the language for applications programs run by the operating systems written in Concurrent Pascal. Both languages are extensions of Niklaus Wirth s Pascal programming language Pascal , and share a common threaded code interpreter . The following describes how Concurrent Pascal differs from Wirth s Pascal. Language description Several constructs in Pascal were removed from Concurrent Pascal for simplicity and security variant records the goto statement and labels Subroutine procedures as parameter s packed array s pointer computer programming pointer types file types and associated standard input output procedures . These omissions make it possible to guarantee, by a combination of compile time checks and minimal run time checking in the threaded code interpreter, that a program can not damage itself or another program by addressing outside its allotted space. Concurrent Pascal includes class, monitor, and process data types. Instances of these types are declared as variables, and initialized in an init statement. Classes and monitors are similar both package private variables and procedures with public procedures called procedure entries . A class instance can be used by only one process, whereas a monitor instance may be shared by processes. Monitors provide the only mechanism for interprocess communication in a Concurrent Pascal program. Only one process can execute within a given monitor ..., and monitor procedures. Processes communicate through monitor procedures. Language rules prevent ... hang up through programming errors.

As a result, there is no risk of invalidating the logic as with systems where logical specification must first be translated to a lower level implementation. The root of the MetateM concept is Gabbay s separation theorem any arbitrary temporal logic formula can be rewritten in a logical equivalence logically equivalent past  &rarr   future form. Execution proceeds by a process of continually matching rules against a history, and firing those rules when antecedent s are satisfied. Any instantiated future time consequents become commitments which must subsequently be satisfied, iteratively generating a model for the formula made up of the program rules. Temporal Connectives The Temporal Connectives of Concurrent MetateM can divided into two categories, as follows Strict past time connectives weak last , strong last , was , heretofore , S since , and Z zince, or weak since . Present and future time connectives next , sometime , always , U until , and W unless . The connectives , , , , , , are unary the remainder are binary. Strict past time connectives Weak last is satisfied now if was true in the previous time. If is interpreted at the beginning of time, it is satisfied despite there being no actual previous time. Hence weak last. Strong last is satisfied now if was true in the previous time. If is interpreted at the beginning of time, it is not satisfied because there is no actual previous time. Hence strong last. Was is satisfied now if was true in any previous moment in time. Heretofore is satisfied now if was true in every previous moment in time ... intelligence Comp sci stub DEFAULTSORT Concurrent Metatem ...   more details



  1. Concurrent validity

    Concurrent validity is a parameter used in sociology, psychology, and other psychometric or behavioral sciences. Concurrent validity is demonstrated where a test correlates well with a measure that has previously been Validity statistics validated . The two measures may be for the same construct, or for different, but presumably related, constructs. The two measures are taken at the same time. This is in contrast to predictive validity , where one measure occurs earlier and is meant to predict some later measure. ref McIntire, S.A. and Miller, L.A., Foundations of Psychological Testing,2nd Edition, Sage Publishing Co., 2005. ref Concurrent validity and predictive validity are two types of criterion related validity. The difference between concurrent validity and predictive validity rests solely on the time at which the two measures are administered. Concurrent validity applies to validation studies in which the two measures are administered at approximately the same time. For example, an employment test may be administered to a group of workers and then the test scores can be correlated with the ratings of the workers supervisors taken on the same day or in the same week. The resulting correlation would be a concurrent validity coefficient. Predictive validity differs only in that the time between taking the test and gathering supervisor ratings is longer, i.e., several months or years. In the example above, predictive validity would be the best choice for validating an employment test, because employment tests are designed to predict performance.

  1. Concurrent lines

    Refimprove date March 2011 In geometry , two or more line mathematics lines are said to be concurrent if they Line line intersection intersect at a single point geometry point . In a triangle , four basic types of sets of concurrent lines are Altitude triangle altitudes , Bisection Angle bisector angle bisectors , Median geometry medians , and perpendicular bisectors A triangle s altitudes run from each Vertex geometry vertex and meet the opposite side at a right angle . The point where the three altitudes meet is the orthocenter . Angle bisectors are rays running from each vertex of the triangle and bisecting the associated angle . They all meet at the incenter . Medians connect each vertex of a triangle to the midpoint of the opposite side. The three medians meet at the centroid . Perpendicular bisectors are lines running out of the midpoints of each side of a triangle at 90 degree angles. The three perpendicular bisectors meet at the circumcenter . Other sets of lines associated with a triangle are concurrent as well. For example, any median which is necessarily a Bisection Triangle area bisectors bisector of the triangle s area is concurrent with two other area bisectors each of which is parallel to a side. ref Dunn, J. A., and Pretty, J. E., Halving a triangle, Mathematical Gazette 56, May 1972, 105 108. ref Compare to Line geometry collinear .

  1. Concurrent jurisdiction

    Concurrent jurisdiction exists where two or more court s from different systems simultaneously have jurisdiction over a specific case. This situation leads to forum shopping , as parties will try to have their lawsuit civil or criminal law criminal case heard in the court that they perceive will be most favorable to them. United States In the United States , concurrent jurisdiction exists to the extent that the United States Constitution permits United States federal court federal courts to hear actions that can also be heard by State court United States state courts . For example, where a party from Alabama sues a party from Florida for a breach of contract , the Alabama party can sue in either the federal court located in Florida under its diversity jurisdiction or in the state court located in Florida under its personal jurisdiction over the defendant . Concurrent jurisdiction may also be created where the United States Congress , in creating a cause of action, permits the courts of the states to hear cases alleging that cause of action. For example, a state court may hear a claim for trademark infringement under the Lanham Act . Concurrent jurisdiction in the United States can also exist between different levels of state courts, and between courts and other government agencies with judicial powers. Different countries can also share concurrent jurisdiction over a case, where different countries have authority over the parties or events giving rise to the cause of action. Title 28 of the United States Code , sections 1331 & 1332 give federal courts concurrent jurisdiction with the state courts over federal question and diversity cases. Medieval Church jurisdiction In the Middle Ages , the Catholic Church Church expanded its jurisdiction in many areas of Europe widely beyond the original scope of ecclesiastical court s concerning spiritual or religious matters, thereby creating concurrent jurisdiction in many civil cases with the courts instituted by secular authorities ...   more details
