  3. Spring Web Flow - Wikipedia

    en.wikipedia.org/wiki/Spring_Web_Flow

    In 2005 the project was introduced into the Spring portfolio by Keith Donald and grew into the official Spring sub-project it is now. The first production ready 1.0 release was made on 2006-10-26. Version 2.0, first released on 2008-04-29, saw a major internal reorganization of the framework to allow better integration with JavaServer Faces.

  4. Spring Integration - Wikipedia

    en.wikipedia.org/wiki/Spring_Integration

    It is a lightweight [clarify] framework that builds upon the core Spring framework. It is designed to enable the development of integration solutions typical of event-driven architectures and messaging-centric architectures [clarify]. [4]: 691–722, §16 Spring Integration is part of the Spring portfolio.

    General scheme of content-based image retrieval. Content-based image retrieval, also known as query by image content and content-based visual information retrieval (CBVIR), is the application of computer vision techniques to the image retrieval problem, that is, the problem of searching for digital images in large databases (see this survey [1] for a scientific overview of the CBIR field).

    Direct image sheaf, the pushforward of a sheaf by a map; Fiberwise integral, the direct image of a differential form or cohomology by a smooth map, defined by "integration on the fibres" Transfer operator, the pushforward on the space of measurable functions; its adjoint, the pull-back, is the composition or Koopman operator

  7. Spring (company) - Wikipedia

    en.wikipedia.org/wiki/Spring_(company)

    Spring (previously known as SpringSource) was a software company founded by Rod Johnson, who also created the Spring Framework, an open-source application framework for enterprise Java applications. VMware purchased Spring for $420 million in August 2009.

  8. Exponential backoff - Wikipedia

    en.wikipedia.org/wiki/Exponential_backoff

    For example, if the ceiling is set at i = 10 in a truncated binary exponential backoff algorithm, (as it is in the IEEE 802.3 CSMA/CD standard [14]), then the maximum delay is 1023 slot times, i.e. 2 10 − 1. Selecting an appropriate backoff limit for a system involves striking a balance between collision probability and latency.

  9. Observer pattern - Wikipedia

    en.wikipedia.org/wiki/Observer_pattern

    Below is an example written in Java that takes keyboard input and handles each input line as an event. When a string is supplied from System.in , the method notifyObservers() is then called in order to notify all observers of the event's occurrence, in the form of an invocation of their update methods.
