Although, in literature various results can be found claiming that fuzzy rule-based systems (FRBSs) possess the universal approximation property, to reach arbitrary accuracy the necessary number of rules are unbounded. Therefore, the inherent property of FRBSs in the original sense of Zadeh, namely that they can be characterized by a semantic relying on linguistic terms is lost. If we restrict ...

AIM To determine whether differing policies with regard to the control of oxygen saturation have any impact on the number of babies who develop retinopathy of prematurity and the number surviving with or without signs of cerebral palsy at one year. METHODS An examination of the case notes of all the 295 babies who survived infancy after delivery before 28 weeks gestation in the north of Engla...

This paper provides the qualitative analysis on a diffusive SIRS epidemic model with logistic source and saturated incidence rate. We first establish uniform boundedness of parabolic system, then explore extinction/persistence infectious disease via basic reproduction number. The effects source, dispersal, saturation, spatial heterogeneity asymptotic behaviors endemic equilibrium are also inves...

in this paper, a non-isothermal two-phase flow in the cathode gas diffusion layer (gdl) of pem fuel cell is modeled. the governing equations including energy, mass and momentum conservation equations are solved by numerical methods. also, the optimal values of the effective parameters such as the electrodes porosity, gas diffusion layer (gdl) thickness and inlet relative humidity are calculated...

a total of 148 groundwater samples were collected from bore wells from thirumanimuttar sub-basin for two seasons to identify major geochemical process activated to alter groundwater chemistry. the study revealed relationships with the lithology and anthropogenic process. groundwater in the region was dominated by na – ca – mg and cl and hco3 types. the (ca +mg) versus tz+ plot for both seas...

The SuperParaMagnetic particles (SPM particles) are used as contrast agents in MRI and produce negative contrast with conventional T2 or T2(∗)-weighted sequences. Unfortunately, the SPM particle detection on images acquired with such sequences is sometimes difficult because negative contrast can be created by artifacts such as air bubbles or calcification. To overcome this problem, new sequence...

In the classical parking problem, unit intervals (“car lengths”) are placed uniformly at random without overlapping. The process terminates saturation, i.e. until no more can be stowed. this paper, we present a generalization of problem in which with an exponential distribution rate parameter $$\lambda $$ . We show that mathematical expectation number saturation satisfies certain integral equat...
