Using a general approach for discretization of continuous life distributions in the univariate & bivariate situations, we have proposed discrete Rayleigh distribution. This distribution has been examined detail with respect to two measures failure rate. Characterization results also studied establish direct link between distribution, and its counterpart. not only expands scope reliability modeling, but provides method approximating probability integrals arising out setting. As an example,...

Synthetic data generation has recently emerged as a substitution technique for handling the problem of bulk needed in training machine learning algorithms. Healthcare, primarily cardiovascular domain is major area where synthetic physiological like Photoplethysmogram (PPG), Electrocardiogram (ECG), Phonocardiogram (PCG), etc. are being used to improve accuracy algorithm. Conventional approach using mathematical formulations lack interpretability. Hence, aim this paper generate PPG signal...

Starting small number measured PPG data, used synthesize healthy as well time-series pertaining coronary artery disease (CAD) by...

The rheological properties of a polyisobutylene (PIB) having molecular weight five times its entanglement were measured, along with interrupted shear flow experiments to quantify the time required for structural recovery following steady state shearing in non-Newtonian regime. reentanglement kinetics was substantially slower (by more than an order magnitude) expectations based on linear relaxation fully entangled material. This result is accord published results concentrated polymer...

This paper introduces a new discretizing approach for evaluating reliability of any complex system where analytic methods fail to offer closed-form solution. Numerical analyses on 4 important engineering items have been used examine the closeness between proposed estimators and simulated values. A comparative study English et al. (1996) ours indicates that our is in no way less efficient. It can also retain TFR, DFR, IFRA properties original distribution.

Automatic identification of genes has been an actively researched area bioinformatics. Compared to earlier attempts for finding genes, the recent techniques are significantly more accurate and reliable. Many current gene-finding methods employ computational intelligence that known be robust when dealing with uncertainty imprecision. In this paper, a detailed survey on existing classical based gene is carried out. This includes brief description before discussing their applications finding....

This article presents a geometrical region-based shape control methodology for navigating cohesive swarm-robotic structure toward the goal even in field occluded by unknown obstacles. In this approach, initially, robotic swarm is conceived to lie within well-defined virtual circular region thus preserving strict interagent cohesiveness among them. However, during progression, evading severely constricted obstacles, circle has been allowed change its and process, varied elliptical shapes are...

Valvular heart diseases are a prevalent cause of cardiovascular morbidity and mortality worldwide, affecting wide spectrum the population. In-silico modeling system has recently gained recognition as useful tool in research clinical applications. Here, we present an in-silico cardiac computational model to analyze effect severity valvular disease on general hemodynamic parameters. We propose multimodal multiscale simulate understand progression associated with mitral valve. The developed...

This paper presents a switching strategy of region-based shape controller for swarm-robotic framework to overcome the traditional obstacle-avoidance problem in virtual structure methodology. In this control approach, initially, robots move as group inside circular region which we conceive be initial structure, while preserving specific pattern, say triangular formation, among them. order avoid static/dynamic obstacles, approaching towards target without any prior knowledge about environment,...

Swarm robots cooperating in a group offer plentiful benefits and can accomplish several jobs that could be otherwise challenging either for human beings or single robot. Here we have considered two evolutionary based control algorithms, namely Bacterial Foraging (BFOA) Particle swarm optimization (PSO), flocking of to predefine objective along an optimum path while avoiding obstacles. During the movement swarm, attraction, repulsion formation coefficients all agents are evaluated using above...
