Unreferenced date December 2009 In computer programming , the scheduler pattern is a software design pattern . It is a Concurrency computer science concurrency pattern used to explicitly control when thread software engineering thread s may execution computers execute single threaded source code code , like write operation to a file. The scheduler pattern uses an object that explicitly sequences waiting threads. It provides a mechanism to implement a scheduling policy , but is independent of any specific scheduling policy &mdash the policy is encapsulated in its own class and is reusable. The Read write lock pattern read write lock pattern is usually implemented using the scheduler pattern to ensure fairness in scheduling. Note that the scheduler pattern adds significant overhead beyond that required to call a synchronized method computer science method . The scheduler pattern is not quite the same as the scheduled task pattern used for real time systems.

The wedge pattern is a commonly found pattern in the price chart s of financially traded assets stocks , Bond finance bonds , Futures contract futures , etc. . The pattern is characterized by a contracting range in prices coupled with an upward trend in prices known as a rising wedge or a downward trend in prices known as a falling wedge . A wedge pattern is considered to be a temporary halt of primary trend. It is a type of formation in which trading activities are confined within converging straight lines which form a pattern. It should take about 3 to 4 weeks to complete the wedge. This pattern has a rising or falling slant pointing in the same direction. It differs from the triangle in the sense that both boundary lines either slope up or down. Price breaking out point creates another difference from the triangle. Falling and rising wedges are a small part of intermediate or major trend. As they are reserved for minor trends, they are not considered to be major patterns. Once that basic or primary Trend lines technical analysis trend resumes itself, the wedge pattern loses its effectiveness as a technical indicator.

The patterns serve as an aid to design city cities and building s. The concept of having collections of patterns , or typical samples as such, is much older. One can think of these collections as forming a pattern language , whereas the elements of this language may be combined, governed by certain rules. Alexander s idea of patterns Alexander s patterns seek to provide a source of proven idea s for individuals and communities to use in constructing their living and built environment working environment . As such their aim is both aesthetic and political to show how beautiful, comfortable and flexible built environments can be constructed, and to enable those people who will inhabit those environments to challenge any solution forced upon them. A pattern records the design decisions taken by many builders in many places over many years in order to resolve a particular problem.

Pattern bargaining is a process in labour relations, where a trade union gains a new and superior entitlement from one employer and then uses that agreement as a precedent to demand the same entitlement or a superior one from other employers. In the United States, pattern bargaining was pioneered by unions such as the United Auto Workers and the Teamsters . The first step of the bargaining process is the identification of a target employer that is most likely to agree to a favorable employment contract. For the selected company, this provides an opportunity to influence the contract for the industry, while the downside is the risk of a labor disruption if negotiations stall or fail. Once this contract has been successfully negotiated and ratified by the unionized workers, the union declares it a pattern agreement and presents it to the other employers as a take it or leave it offer. In Australia , pattern bargaining was specifically outlawed under the now repealed WorkChoices legislation. The law was repealed by the Labor party after their victory in the Australian federal election, 2007 2007 election , but Labor s Fair Work Act, which came into force on 1 July 2010, still outlaws pattern bargaining.
