We identify key problems and present corresponding research directions for the incremental construction of timed models for real-time systems. We present a framework that may provide some solutions and an associated methodology for model construction. Timed models of real-time systems are obtained by adding timing constraints to their application software. These constraints take into account ex...

The journal Real-Time Systems publishes papers, short papers and correspondence articles that concentrate on real-time computing principles and applications. The contents include research papers, invited papers, project reports and case studies, standards and corresponding proposals for general discussion, and a partitioned tutorial on real-time systems as a continuing series. The range of cov...

Embedded systems have experienced a dramatic increase in ubiquity and functionality. They have penetrated our life to a degree where we rely heavily on them and at the same time entrust them with vast amounts of personal information. The trust placed in them does not necessarily mean they are trustworthy. Within this chapter we summarise past research of the ERTOS group at NICTA in the area and...

The real time computing systems respond to input immediately therefore there are strict timing constraints that have to be met to get the correct output. Real time applications are expected to generate output in response to stimuli within some upper bound. Real t ime systems change its state in real time even after the controlling processor has stopped its execution. The real time application r...

the purpose of this paper is to review the real options literature, which has provided a promising area of development in the capital budgeting process of the firm, and to emphasize that employing the new theory, as part of the information system, depends heavily on the implementation of computer information systems, as decisions support systems (dsss) . the paper concentrates on two important ...

Last Lecture: • Model of timed behaviour: state variables and their interpretation • First order predicate-logic for requirements and system properties This Lecture: • Educational Objectives: Capabilities for following tasks/questions. • Read (and at best also write) Duration Calculus formulae. • Content: • Classes of requirements (safety, liveness, etc.) • Duration Calculus: Assertions, Terms,...

This study presents empirical evidence concerning the effect of different accounting standard on earnings management. Prior studies have shown that accounting standards influence earnings management. Tighter accounting standards regime restricts management’s descretion to manipulate accruals, and at the same time, induce more costly real earnings management activities. To investigate this iss...
