Distributed systems are employed in countless applications such as information systems, robotics, etc. Lack of central control makes the design of such systems a challenging task because of possible unwanted behavior at runtime, commonly known as emergent behavior. Developing a methodology to detect emergent behavior in the pre-implementation stages of the(More)
A Hybrid Mutation Particle Swarm Optimisation (HMPSO) technique for improved estimation of Available Transfer Capacity (ATC) as a decision criterion is proposed in this paper. First, this is achieved by comparing a typical application of the Particle Swarm Optimisation (PSO) technique with conventional Genetic Algorithm (GA) methods. Next, a multi-objective(More)
We study the notion of safe realizability and implied scenarios for Message Sequence Chart (MSC) specifications with the following contributions: (1) We investigate the cause of implied scenarios and show that even though implied scenarios are an artifact of the distributed and global system behaviour, nevertheless, they are the result of the nondeterminism(More)
A flexible data input layer architecture (FDILA) has been designed and developed by Tavakoli et al. for providing a generic tool to transfer data from a wide series of data acquisition devices into higher levels of information processing systems. Data collected by mobile devices such as GPS and PDA applications are among important inputs for evaluating(More)
Multi-agent systems (MAS) are efficient solutions for commercial applications such as information retrieval and search. In a MAS, agents are usually designed with distribution of functionality and control. Lack of central control implies that the quality of service of MAS may be degraded because of possible unwanted behavior at the runtime, commonly known(More)
The purpose of this paper is in two folds; the first is to undertake a thorough appraisal of the existing input variable selection (IVS) methods in the context of time-critical and resource-limited dimensionality reduction problems. The second is to demonstrate further improvements and the application of a recently proposed time-critical sensitivity(More)
Efficient feature extraction strategies play an important role in palmprint recognition systems. Among various feature extraction methods, orientation methods such as Competitive Code and Half Orientation Code are the baseline ones. They encode responses of a bank of orientational filters into a binary representation and can match a test palmprint sample in(More)
Safe realizability of Message Sequence Charts (MSCs) specifications is a measure of whether or not there exists a distributed implementation of the specification such that it is deadlock free and shows exactly the behaviours specified in the specification. There are also some works that given a specification, can answer whether it is safely realizable or(More)
