Distribution is a well-known solution to increase performance and provide load balancing in case you need optimal resource utilization. Together with replication it also allows improved reliability, accessibility and fault-tolerance. However since the amount of data is large there is a problem of maintaining meta-information about distribution and finding needed data fragments during execution ...

Caching of frequently accessed data in ad hoc networks is a potential technique that can improve the data access, performance and availability. A cooperative cache-based data access framework lets mobile node cache the data or the path to the data to reduce query delays and improve data accessibility. Due to mobility and resource constraints of ad hoc networks, cooperative caching techniques de...

In this paper, the authors use a mixed methods study, including a survey and follow up interviews, to investigate the concerns that elementary educators in a school district in British Columbia have regarding the diffusion and integration of Information and Communication Technologies (ICT) in their teaching. The research participants identified four major categories of concerns: the philosophy ...

The Median-Path problem consists of locating a path on a network, minimizing a function of two parameters: accessibility to the path and total cost of the path. Applications of this problem can be found in transportation planning, water resource management and fluid transportation. The Central-Path problem is defined similarly. In this paper, we give a construction on a graph G which produces a...

Ad hoc networks are formed opportunistically as mobile devices come within wireless communication range of each other. Since individual devices are typically subject to severe resource limitations, it is both possible and desirable for a device to enhance its functionality by taking advantage (in a cooperative manner) of capabilities available on other devices. Service provision refers to the p...

Case study libraries have emerged from the development of educational resource tools as a potent contender due to their accessibility and flexibility in supporting various aspects of a learning curriculum. However, despite their advantages, the effective realization of such a tool presents a number of design challenges in its implementation. This study explores the ability of a collection of su...

The Harvesting Day is an initiative to ensure the visibility, accessibility and description of language resources by means of a basic and metadata schema. This initiative believes in a change of strategy: resource and technology providers must be aware of the importance of ensuring the visibility of their resources, as well as the documentation thereof. Once language resources descriptions are ...

The disparities in prostate cancer incidence and mortality continue to be a global public health problem. Efforts to address the prostate cancer disparity in black men have been met with a number of challenges, specifically in the accessibility to biospecimens in the context of global prostate cancer collaborations. During the International Educational Workshop at the Science of Global Prostate...

An educational resource targeting children with learning difficulties should be based on special teaching aids to achieve its educational purposes. Teaching supported by new technologies should guarantee the accessibility of the contents introduced over the web, as well as through the use of software applications. In this paper, we present a methodology for creating such resources and its appli...

This study focuses on the intellectual accessibility of information in indigenous languages, using Zulu, one of the main indigenous languages in South Africa, as a test case. Both Cross-Lingual Information Retrieval (CLIR) and metadata are discussed as possible means of facilitating access and a bilateral approach combining these two methods is proposed. Popular CLIR approaches and their resour...
