Application of Internet techniques into online collaborative design and manufacture

A research project in Web-enabled collaborative design and manufacture has been conducted. The major tasks of the project include the development of a Web-enabled environment for collaboration, online collaborative CAD/CAM, remote execution of large size programs (RELSP), and distributed product design. The tasks and Web/Internet techniques involved are presented first, followed by detail description of two approaches developed for implementation of the research: (1) a client-server approach for RELSP, where the following Internet techniques are utilized: CORBA, Microsoft’s Internet information server, Tomcat server, JDBC and ODBC; (2) Web-Services supported collaborative CAD which enables geographically dispersed designers jointly conduct a design task in the way of speaking and seeing each other and instantaneously modifying the CAD drawing online.

'Grooming' and the Sexual Abuse of Children:Institutional, Internet and Familial Dimensions

‘Grooming’ and the Sexual Abuse of Children: Institutional, Internet and Familial Dimensions critically examines the official and popular discourses on grooming, predominantly framed within the context of on-line sexual exploitation and abuse committed by strangers, and institutional child abuse committed by those in positions of trust.

Set against the broader theoretical framework of risk, security and governance, this book argues that due to the difficulties of drawing clear boundaries between innocuous and harmful motivations towards children, pre-emptive risk-based criminal law and policy are inherently limited in preventing, targeting and criminalising ‘grooming’ behaviour prior to the manifestation of actual harm. Through examination of grooming against the complexities of the onset of sexual offending against children and its actual role in this process, the author broadens existing discourses by providing a fuller, more nuanced conceptualisation of grooming, including its role in intra-familial and extra-familial contexts. There is also timely discussion of new and emerging forms of grooming, such as ‘street’ or ‘localised’ grooming, as typified by recent cases in Rochdale and Oldham, and ‘peer-to-peer’ grooming.

The first inter-disciplinary, thematic, and empirical investigation of grooming in a multi-jurisdictional context, ‘Grooming’ and the Sexual Abuse of Children draws on extensive empirical research in the form of over fifty interviews with professionals, working in the fields of sex offender risk assessment, management or treatment, as well as child protection or victim support in the four jurisdictions of the United Kingdom and the Republic of Ireland. Impeccably presented and meticulously considered, this book will be of interest to criminologists and those working and studying in the field of policing and criminal justice studies, as well as policy makers and practitioners in the areas of child protection and sex offender management.

Loss-of-Mains Detection by Internet Based ROCOF

This paper considers the enhancement of loss-of-mains detection by use of a differential rate-of-change-of-frequency relay to reduce nuisance tripping and improve sensitivity to small excursions in frequency. The telecommunications media which might carry the differential ROCOF signal are reviewed with a focus on channel latency, bandwidth and security.

Internet Based Loss-of-Mains Detection for Distributed Generation

This paper discusses methods of using the Internet as a communications media between distributed generator sites to provide new forms of loss-of-mains protection. An analysis of the quality of the communications channels between several nodes on the network was carried out experimentally. It is shown that Internet connections in urban environments are already capable of providing real-time power system protection, whilst rural Internet connections are borderline suitable but could not yet be recommended as a primary method of protection. Two strategies of providing loss-of-mains across Internet protocol are considered, broadcast of a reference frequency or phasor representing the utility and an Internet based inter-tripping scheme.
