Distributed RBAC for subscription-based remote network services
The problems of identity management inherent in distributed subscription-based resource sharing are investigated in this thesis. The thesis introduces a concept of authentication delegation and distributed RBAC (DRBAC) to support fine granular access control across multiple autonomous resource …

An investigation into information security in general medical practice
… with general practice as the cornerstone of this distributed environment. In this progressively more electronic state, general practice is charged with the responsibility to ensure confidentiality and privacy of patient infonnation. However, evidence suggests that protection of patient information …

Distributed data management for large scale applications
… computing centres around the world. Worldwide distributed data management is particularly important when there is a lot of data, more than can fit in a single computer or even in a single data centre. Designing systems to cope with the demanding requirements of these applications is the focus …

A distributed system architecture for spatial data management to support engineering modeling
… Modeling Language. The second level examines the distributed environment that enables such collaboration, and proposes a three-tier distributed system architecture. The interdisciplinary Urban Respiration project provides a context and examples illustrating the need for such design. A prototype …

AdaTAD - a debugger for the Ada multi-task environment
… implemented in Ada it becomes portable among all environments which support the Ada language. This offers the advantage that a single debugger is portable to many different machine architectures. Therefore, separate debuggers are not necessary for each implementation of Ada. Moreover, since AdaTAD …

A control framework for distributed (parallel) processing environments
A control framework for distributed (parallel) processing environments is introduced. The control framework supplies a centralized control sub-system within a distributed environment to manage the resources available on a network of computers. Special attention is centered on the execution …

OODSF: an object-oriented data specification framework in a heterogeneous computing environment
… to facilitate programming in a heterogeneous distributed environment. Using the OODSF, C++ language bindings of commonly used specification languages, such as Abstract Syntax Notation 1 (ASN.l) and Interface Definition Language (IDL), can be defined. The OODSF defines C++ class libraries for …

Mobile Collaborative Virtual Environments: A Paradigm Shift from Desktop to Mobile Online Communities
… are myriad examples of virtual communities and environments available for collaborative activities. However, most of these environments are confined to the desktop and thus preclude collaboration while users are on the move. Through a scenario-based design process, this article establishes the …

Advances in parallel overset domain asembly
… boundaries. Performing Domain Assembly in a distributed environment is computationally expensive and inherently poorly load balanced due to the solver partitioning. Dynamic load balancing is therefore required to alleviate the imbalance and make very large Overset problems feasible. In this …

SDTDMn0 : a multidimensional distributed data mining framework supporting time series data analysis for critical care research
… areas in hospitals. The multidimensional and distributed nature of the data further adds another layer of complexity as physiological changes can occur in one data stream or can be cross-correlated between several streams. With the collection and storage of electronic data becoming a global …

Distributed Denial of Service Attack Detection
<p>Distributed Denial of Service (DDoS) attacks on web applications has been a persistent threat. Successful attacks can lead to inaccessible service to legitimate users in time and loss of business reputation. Most research effort on DDoS focused on network layer attacks. Existing approaches on …

Distributed coordination in network information theory
… very little about efficient communication in a distributed environment. In distributed wireless networks, there appears to be an interesting and complex trade-off between trying to take advantage of independent noisy signals at different relays and closely coordinating relay transmissions to a …

Distributed problem solving environments for scientific computing
… is to research the issues involved in creating distributed problem solving environments for scientific computing. As part of our evaluation, we have developed a distributed problem solving environment called DPSolve which combines a very high level language, an interactive X Windows interface …

Speedes: A Case Study Of Space Operations
… Operations Flow using the Synchronous Parallel Environment for Emulation and Discrete-Event Simulation (SPEEDES), an object-oriented multi-computing architecture. SPEEDES is a unified parallel simulation environment, which allocates events over multiple processors to get simulation speed up. Its …

Mobile agent-based attack-resistant architecture for Distributed Intrusion Detection system
The majority of the Distributed Intrusion Detection systems lack measures for providing security and integrity to their own components. The hierarchical organization and the static nature of the intrusion detection components in a largely distributed environment make them the likely targets of …

Scaling data mining activities on very large datasets
… perform itemset extraction in a parallel and/or distributed environment, is also described. To address the manageability of frequent itemsets, a concise disk-based representation, with a set of querying techniques, is proposed. This work has been preliminarly validated in the Semantic Web domain, …
