BACKGROUND Assessment of the nociceptive withdrawal reflex (NWR) is frequently applied to probe the excitability level of the spinal nociceptive circuitry. In humans, the NWR threshold (NWR-T) is often estimated by applying electrical stimulation over the sural nerve at the lateral malleolus. Such stimulation may be associated with substantial pain and discomfort rendering completion of the ass...

The paper proposes a novel paradigm for accurate reliability estimation of ubiquitous systems. The proposed prototype differs from all conventional software reliability models as it does not rely on any kind of post failure data, questionable assumptions or statistical distributions. The paradigm instead is based on software state to state transition at runtime. Using this state to state transi...

When navigating through the environment, our brain needs to infer how far we move and in which direction we are heading. In this estimation process, the brain may rely on multiple sensory modalities, including the visual and vestibular systems. Previous research has mainly focused on heading estimation, showing that sensory cues are combined by weighting them in proportion to their reliability,...

Damage scenarios for large networks are considered. The cascade scenario is described by means of powers of adjacency matrix. More difficult probabilistic variants of the large network damage are modeling by Markov’s chains. For reliability augmentation of networks we add a set of random intermediate agents with big dimensionality. It provides high reliability of all system even with low reliab...

Reliability is one of the most important quality dimensions for web services. Current reliability models for composite web service assume the statistical independence of its component web services, which is often not the case. In this paper, we research on the reliability correlation of component web services by identifying common-cause failures (CCF) and propose a tree-based reliability model ...

Mobile Agent based Systems (MAS) is one of the fastest growing and emerging areas for application development in recent past. A mobile agent is a computer program that acts autonomously on behalf of a user or application moving in the heterogeneous communication environment. To ensure fault and failure free operation of mobile agent based commercial applications, reliability issues need to be a...

-One critical issue for routing in mobile ad hoc networks (MANET) is how to select a reliable path that can last longer since mobility may cause radio links to break frequently. To answer this question, a criterion that can judge path reliability is needed. The reliability of a path depends on the availability of the links1 constituting the path. However, how to measure link availability to ans...

In this paper, Exponential Power (EP) model is proposed to analyze the software reliability data and the present work is an attempt to represent that the model is as software reliability model. The approximate MLE using Artificial Neural Network (ANN) method and the Markov chain Monte Carlo (MCMC) methods are used to estimate the parameters of the EP model. A procedure is developed to estimate ...

Software reliability models play a dominant role in the analysis of failure data for real time command and control software systems. Goel and Okumoto model is a non homogenous Poisson Process software reliability growth model which has gained a lot of importance in software reliability analysis and prediction. The process of parameter estimation is the major drawback of this model because the i...
