Communication mechanisms and middleware for distributed video surveillance

A new generation of advanced surveillance systems is being conceived as a collection of multi-sensor components such as video, audio and mobile robots interacting in a cooperating manner to enhance situation awareness capabilities to assist surveillance personnel. The prominent issues that these systems face are: the improvement of existing intelligent video surveillance systems, the inclusion of wireless networks, the use of low power sensors, the design architecture, the communication between different components, the fusion of data emerging from different type of sensors, the location of personnel (providers and consumers) and the scalability of the system. This paper focuses on the aspects pertaining to real-time distributed architecture and scalability. For example, to meet real-time requirements, these systems need to process data streams in concurrent environments, designed by taking into account scheduling and synchronisation. The paper proposes a framework for the design of visual surveillance systems based on components derived from the principles of Real Time Networks/Data Oriented Requirements Implementation Scheme (RTN/DORIS). It also proposes the implementation of these components using the well-known middleware technology Common Object Request Broker Architecture (CORBA). Results using this architecture for video surveillance are presented through an implemented prototype.

Developing children and young people’s participation in strategic processes: the experience of the Children’s Fund Initiative

The extent of children’s and young people’s participation activities has increased considerably among statutory, voluntary and community sector organisations across the UK in recent years. The Children’s Fund, a major government initiative launched in 2000, represents a systematic drive towards promoting children and young people’s participation in planning, implementing and evaluating preventative services within all 149 local authority areas in England. Based on research carried out by the National Evaluation of the Children’s Fund, this paper explores the experience of Children’s Fund partnerships of engaging children and young people in strategic processes.
