Computing the output of fuzzy systems usually passes through three stages i.e. fuzzification, inference, and defuzzification. The computation of the output requires too many operations and considerable time. This apparently discourages the use of fuzzy systems in time-critical applications. In this paper, a new two-stage representation of fuzzy systems, which reduces the operations needed to co...

Real-time systems are being increasingly used in several applications which are time-critical in nature. Fault tolerance is an essential requirement of such systems, due to the catastrophic consequences of not tolerating faults. In this paper, we study a scheme that guarantees the timely recovery from multiple faults within hard real-time constraints in uniprocessor systems. Assuming earliest-d...

Many applications require computational systems to respond to queries by a particular deadline. Failure to meet the deadlines may render the returned solution useless. Moreover, the deadlines of such time-critical applications are often uncertain at system design time. Anytime algorithms have been suggested to cope with these challenges by trading the quality of the solutions for the reactivene...

In this paper, we propose a superior technique for distributed time-critical communication using AIDA, a novel elaboration on Michael O. Rabin's IDA 19]. We show that using a small dynamically-controlled amount of redundancy, stringent timing constraints imposed on periodic as well as sporadic communication requests in a distributed real-time system can be fulllled up to any degree of conndence...

Many time-critical applications require dynamic scheduling with predictable performance. Tasks corresponding to these applications have deadlines to be met despite the presence of faults. In this paper , we propose an algorithm to schedule dynamically arriving real-time tasks with resource and fault-tolerant requirements on to multiprocessor systems. The tasks are assumed to be non-preemptable ...

This paper focuses on the Firm Real-Time requirements of Time-Critical Wide Area Measurement and Control systems, that are expected to play a major role in future Smart Grids. It analyses the operation of these systems and identifies their communication traffic characteristics. It shows that these characteristics are significantly different to those of the current Near Real-Time Wide Area Measu...

Digital convergence is precipitating the addition of soft real-time applications to mainstream desktop and server operating environments. Most traditional debuggers for mainstream systems lack a notion of temporal correctness, making them unsuitable for real-time system design and analysis. We propose leveraging complete system simulation to build a temporal debugger capable of analyzing mixed ...

Background: There is limited research on the association between opportunity cost of time and sports and exercise due to lack of data on opportunity cost of time. Using a sample of 14142 adults from Health Survey for England (2006), we develop and test a composite index of opportunity cost of time (to address the current issues with data constraint on opportunity cost of time) in order to explo...
