Interoperable and transparent dynamic deployment of web services for service oriented grids

Dynamic deployment of Web services is a term used frequently when describing the selection and deployment of a service to a grid host. Although current grid systems (such as Globus) provide dynamic deployment, the requirements of the service being deployed are not considered. Therefore truly dynamic deployment cannot be achieved as the services deployed are restricted to the grid system used. We present a dynamic deployment mechanism as part of self configuration in a service oriented grid environment. The dynamic deployment mechanism takes the requirements of the service into consideration, including parameters such as the operating system required to execute the service, the required software libraries, any additional required software packages, price and Quality of Service (QoS) parameters.

Being a ‘wog’ in Melbourne – young people's self-fashioning through discourses of racism

The Greek community in Melbourne, Australia, is large and has a long history in the city. It is diverse and associated with a range of cultural, social and political structures. It has strong transnational links and in many ways exemplifies ‘diasporic’ in contradistinction to ‘migrant’. This paper focuses on young people from this community, particularly those who attend schools established to promote Greek language and cultural maintenance. In this paper, we examine such students’ explorations of their cultural identifications, most specifically how they adopt the term ‘wog’. This term is complex and its place in Australian discourse has shifted over time. Tracking these shifts and considering them as a context for these young people's use of the term allows us to consider the processes involved in their self-fashioning. We argue that their uptake of ‘wog’ involves the deployment of irony, given their awareness of its strong association with racism. We are also interested in the potential for women's experience to be silenced through the common association between ‘wog’ and protest masculinities. We argue that these students’ use of the term illustrates self-fashioning that provides insights into the complexities that surround cultural identification at the micro level, including schooling, but also in the broader context of globalisation.

An alternative node deployment scheme for WSNs

© 2001-2012 IEEE. Sensing coverage is a fundamental design problem in wireless sensor networks (WSNs). This is because there is always a possibility that the sensor nodes may function incorrectly due to a number of reasons, such as failure, power, or noise instability, which negatively influences the coverage of the WSNs. In order to address this problem, we propose a fuzzy-based self-healing coverage scheme for randomly deployed mobile sensor nodes. The proposed scheme determines the uncovered sensing areas and then select the best mobile nodes to be moved to minimize the coverage hole. In addition, it distributes the sensor nodes uniformly considering Euclidean distance and coverage redundancy among the mobile nodes. We have performed an extensive performance analysis of the proposed scheme. The results of the experiment show that the proposed scheme outperforms the existing approaches.
