Timestamps in Message-Passing Systems That Preserve the Partial Ordering

C. Fidge
Computer Science
1988

This paper presents algorithms for timestamping events in both synchronous and asynchronous n1essage-passing programs that allow for access to the partial ordering in herent in a parallel system. Expand

Logical time in distributed computing systems

Computer Science
Computer
1 August 1991

The partial ordering of events as defined by their causal relationships, that is, the ability of one event to directly, or transitively, affect another is defined. Expand

Current Research in Risk-aware Business Process Management―Overview, Comparison, and Gap Analysis

This paper compares and classifies current approaches in the area of risk-aware business process management in order to identify and explain relevant research gaps. Expand

Partial orders for parallel debugging

C. Fidge
Computer Science
PADD '88
1 November 1988

We explore use of the partially ordered relation "happened before" to augment both centralized and distributed parallel debuggers to ensure that such errors are always detected and that the results produced by the debugger are unaffected by the non-determinism inherent in the partial ordering.

1 September 2009

We present a new way of creating a simulation model for a business process supported by a workflow management system, in which we integrate design, historic, and state information. Expand

Access Control Requirements for Processing Electronic Health Records

B. Alhaqbani, C. Fidge
Engineering, Computer Science
Business Process Management Workshops
24 September 2007

We review the traditional security models for access control, Discretionary Access Control, Mandatory Access Control and Role-Based Access control, and use a case study to demonstrate that no single one of them is sufficient in a federated healthcare environment. Expand

Security Metrics for Object-Oriented Designs

B. Alshammari, C. Fidge, Diane Corney
Computer Science
21st Australian Software Engineering Conference
6 April 2010

We focus on the design of an object-oriented application and define a number of information security metrics derivable from a program’s design artifacts. Expand

Further evidence of a relationship between explaining, tracing and writing skills in introductory programming

R. Lister, C. Fidge, Donna Teague
Computer Science
ITiCSE '09
6 July 2009

We found that students who tend to perform reasonably well at code writing tasks have also usually acquired the ability to both trace code and explain code. Expand

Business Process Simulation for Operational Decision Support

Engineering, Medicine
Business Process Management Workshops
24 September 2007

We investigate the requirements for a process simulation environment that allows simulation experiments to start from an intermediate execution state. Expand

Workflow Simulation for Operational Decision Support Using Design, Historic and State Information

Computer Science
BPM
2 September 2008

We present a new way of creating a simulation model for a business process supported by a workflow management system, in which we integrate design, historic, and state information. Expand
