Concurrence
In Western jurisprudence, concurrence (also contemporaneity or simultaneity) is the apparent need to prove the simultaneous occurrence of both ("guilty action") and ("guilty mind"), to constitute a crime; except in crimes of strict liability. In theory, if the does not hold concurrence in point of time with the then no crime has been committed. Discussion Suppose for example that the accused accidentally injures a pedestrian while driving. Aware of the collision, the accused rushes from the car only to find that the victim is a hated enemy. At this point, the accused joyfully proclaims his pleasure at having caused the injury. The conventional rule is that no crime has been committed. The ''actus reus'' is complete, and no rule of ratification applies in the criminal law. Whereas in the law of agency, a principal may retrospectively adopt a transaction as if the agent had originally been authorised to conclude an agreement with a third party ("ratification" of the age ...

Concurring Opinion
In law, a concurring opinion is in certain legal systems a written opinion by one or more judges of a court which agrees with the decision made by the Majority opinion, majority of the court, but states different (or additional) reasons as the basis for their decision. When no absolute majority of the court can agree on the basis for deciding the case, the decision of the court may be contained in a number of concurring opinions, and the concurring opinion joined by the greatest number of judges is referred to as the plurality opinion. As a practical matter, concurring opinions are slightly less useful to lawyers than majority opinions. Having failed to receive a majority of the court's votes, concurring opinions are not binding precedent and cannot be cited as such. But concurring opinions can sometimes be cited as a form of persuasive precedent (assuming the point of law is one on which there is no binding precedent already in effect). The conflict in views between a majority op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concurrent Estate
In property law, a concurrent estate or co-tenancy is any of various ways in which property is owned by more than one person at a time. If more than one person owns the same property, they are commonly referred to as co-owners. Legal terminology for co-owners of real estate is either co-tenants or joint tenants, with the latter phrase signifying a right of survivorship. Most common law jurisdictions recognize tenancies in common and joint tenancies. Many jurisdictions also recognize tenancies by the entirety, which is effectively a joint tenancy between married persons. Many jurisdictions refer to a joint tenancy as a joint tenancy with right of survivorship, but they are the same, as every joint tenancy includes a right of survivorship. In contrast, a tenancy in common does not include a right of survivorship. The type of co-ownership does not affect the right of co-owners to sell their fractional interest in the property to others during their lifetimes, but it does affect ...

Concurrent Resolution
A concurrent resolution is a resolution (a legislative measure) adopted by both houses of a bicameral legislature that lacks the force of law (is non-binding) and does not require the approval of the chief executive ( president). Concurrent resolutions are typically adopted to regulate the internal affairs of the legislature that adopted them, or for other purposes, if authority of law is not necessary (such as in the cases of awards or recognitions). United States Congress In the United States Congress, a concurrent resolution is a resolution passed by both the House of Representatives and the Senate but is not presented to the President for signature and does not have the force of law. In contrast, joint resolutions and bills are presented to the President and, once signed or approved over a veto, are enacted and have the force of law. Concurrent resolutions are generally used to address the sentiments of both chambers or to deal with issues or matters affecting both hous ...

Concurrent Sentence
In criminal law, a sentence is the punishment for a crime ordered by a trial court after conviction in a criminal procedure, normally at the conclusion of a trial. A sentence may consist of imprisonment, a fine, or other sanctions. Sentences for multiple crimes may be a concurrent sentence, where sentences of imprisonment are all served together at the same time, or a consecutive sentence, in which the period of imprisonment is the sum of all sentences served one after the other. Additional sentences include intermediate, which allows an inmate to be free for about 8 hours a day for work purposes; determinate, which is fixed on a number of days, months, or years; and indeterminate or bifurcated, which mandates the minimum period be served in an institutional setting such as a prison followed by street time period of parole, supervised release or probation until the total sentence is completed. If a sentence is reduced to a less harsh punishment, then the sentence is said to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concurrency (computer Science)
Concurrency refers to the ability of a system to execute multiple tasks through simultaneous execution or time-sharing (context switching), sharing resources and managing interactions. Concurrency improves responsiveness, throughput, and scalability in modern computing, including: * Operating systems and embedded systems * Distributed systems, parallel computing, and high-performance computing * Database systems, web applications, and cloud computing Related concepts Concurrency is a broader concept that encompasses several related ideas, including: * Parallelism (simultaneous execution on multiple processing units). Parallelism executes tasks independently on multiple CPU cores. Concurrency allows for multiple ''threads of control'' at the program level, which can use parallelism or time-slicing to perform these tasks. Programs may exhibit parallelism only, concurrency only, both parallelism and concurrency, neither. * Multi-threading and multi-processing (shared ...

Concurrent Computing
Concurrent computing is a form of computing in which several computations are executed '' concurrently''—during overlapping time periods—instead of ''sequentially—''with one completing before the next starts. This is a property of a system—whether a program, computer, or a network—where there is a separate execution point or "thread of control" for each process. A ''concurrent system'' is one where a computation can advance without waiting for all other computations to complete. Concurrent computing is a form of modular programming. In its paradigm an overall computation is factored into subcomputations that may be executed concurrently. Pioneers in the field of concurrent computing include Edsger Dijkstra, Per Brinch Hansen, and C.A.R. Hoare. Introduction The concept of concurrent computing is frequently confused with the related but distinct concept of parallel computing, Pike, Rob (2012-01-11). "Concurrency is not Parallelism".

Concurrence (quantum Computing)
In quantum information science, the concurrence is a state invariant involving qubits. Definition The concurrence is an entanglement monotone (a way of measuring entanglement) defined for a mixed state of two qubits as: : \mathcal(\rho)\equiv\max(0,\lambda_1-\lambda_2-\lambda_3-\lambda_4) in which \lambda_1,...,\lambda_4 are the eigenvalues, in decreasing order, of the Hermitian matrix :R = \sqrt with :\tilde = (\sigma_\otimes\sigma_)\rho^(\sigma_\otimes\sigma_) the spin-flipped state of \rho and \sigma_y a Pauli spin matrix. The complex conjugation ^* is taken in the eigenbasis of the Pauli matrix \sigma_z. Also, here, for a positive semidefinite matrix A, \sqrt denotes a positive semidefinite matrix B such that B^2=A. Note that B is a unique matrix so defined. A generalized version of concurrence for multiparticle pure states in arbitrary dimensions (including the case of continuous-variables in infinite dimensions) is defined as: : \mathcal_(\rho)=\sqrt in which \r ...

Concurrent Computer Corporation
Concurrent Computer Corporation was an American computer company, in existence from 1985 to 2017, that made real-time computing and parallel processing systems. Its products powered a variety of applications including process control, simulators, data acquisition, and video-on-demand. It was based in Monmouth County, New Jersey, initially, and then later in Fort Lauderdale, Florida and Duluth, Georgia. Origins and initial efforts The company was created in November 1985 when the computing division of Perkin-Elmer, the Data Systems Group, was spun off as a separate company. The computing group, which had started out as the company Interdata before Perkin-Elmer acquired it in 1974, had been profitable with sales of $259 million, but had tended to have reduced visibility within the computing industry due to being owned by a diversified parent. At first, the new company was a wholly owned subsidiary of Perkin-Elmer, but with the intentions of putting a minority ownership in the comp ...

Concurrent DOS
Multiuser DOS is a real-time multi-user multi-tasking operating system for IBM PC-compatible microcomputers. An evolution of the older Concurrent CP/M-86, Concurrent DOS and Concurrent DOS 386 operating systems, it was originally developed by Digital Research and acquired and further developed by Novell in 1991. Its ancestry lies in the earlier Digital Research 8-bit operating systems CP/M and MP/M, and the 16-bit single-tasking CP/M-86 which evolved from CP/M. When Novell abandoned Multiuser DOS in 1992, the three master value-added resellers (VARs) DataPac Australasia, Concurrent Controls and Intelligent Micro Software were allowed to take over and continued independent development into Datapac Multiuser DOS and System Manager, CCI Multiuser DOS, and IMS Multiuser DOS and REAL/32. The FlexOS line, which evolved from Concurrent DOS 286 and Concurrent DOS 68K, was sold off to Integrated Systems, Inc. (ISI) in July 1994. Concurrent CP/M-86 The initial version of CP/M-86 ...

Lighthouse Design
Lighthouse Design Ltd. was an American software company that operated from 1989 to 1996. Lighthouse developed software for NeXT computers running the NeXTSTEP operating system. The company was founded in 1989 by Alan Chung, Roger Rosner, Jonathan Schwartz, Kevin Steele and Brian Skinner, in Bethesda, Maryland. Lighthouse later moved to San Mateo, California. In 1996, Lighthouse was acquired by Sun Microsystems. History Two of the first products developed at Lighthouse were Diagram! and Exploder. Diagram! was a drawing tool, originally called BLT (for Box-and-Line Tool) in which objects (boxes) are connected together using "smart links" (lines) to construct diagrams such a flow charts. Exploder was a programming tool for storing Objective-C objects in a relational database. Lighthouse marketed Diagram! directly, and in 1991 spun off the Exploder into a new startup, Persistence Software. Persistence Software went public with an IPO on June 25, 1999. Lighthouse went on to deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concurrent Engineering
Concurrent engineering (CE) or concurrent design and manufacturing is a work methodology emphasizing the parallelization of tasks (i.e. performing tasks concurrently), which is sometimes called simultaneous engineering or integrated product development (IPD) using an integrated product team approach. It refers to an approach used in product development in which functions of design engineering, manufacturing engineering, and other functions are integrated to reduce the time required to bring a new product to market. By completing the design and manufacturing stages at the same time, products are produced in less time while lowering cost. Although concurrent design and manufacturing requires extensive communication and coordination between disciplines, the benefits can increase the profit of a business and lead to a sustainable environment for product development. Concurrent design and manufacturing can lead to a competitive advantage over other businesses as the product may be produ ...
