The concept of quasi-coincidence of a fuzzy interval value with an interval valued fuzzy set is considered. In fact, this is a generalization of quasi-coincidence of a fuzzy point with a fuzzy set. By using this new idea, the notion of interval valued (∈,∈ ∨q)-fuzzy filters in BL-algebras which is a generalization of fuzzy filters of BL-algebras, is defined, and related properties are investiga...

OBJECT The treatment of hydrocephalus requires insight into the intracranial dynamics in the patient. Resistance to CSF outflow (R0) is a clinically obtainable parameter of intracranial fluid dynamics that quantifies the apparent resistance to CSF absorption. It is used as a criterion for the selection of shunt candidates and serves as an indicator of shunt performance. The R0 is obtained clini...

In this paper, the analysis of a schistosomiasis infection model that involves human and intermediate snail hosts as well as an additional mammalian host and a competitor snail species is studied by constructing Lyapunov functions and using a Krasnoselkii sublinearity trick. We derive the basic reproduction number R0 for the deterministic model, and establish that the global dynamics are comple...

More general form of the notion of quasi-coincidence of a fuzzy point with a fuzzy subset is considered, and generalization of fuzzy fated of R0-algebras is discussed. The notion of an (∈,∈∨ qk)-fuzzy fated filter in a R0-algebra is introduced, and several properties are investigated. Characterizations of an (∈,∈∨ qk)-fuzzy fated filter in an R0-algebra are discussed. Using a collection of fate...

We investigate the merit of deriving an estimate of the basic reproduction number R0 early in an outbreak of an (emerging) infection from estimates of the incidence and generation interval only. We compare such estimates of R0 with estimates incorporating additional model assumptions, and determine the circumstances under which the different estimates are consistent. We show that one has to be ...

Two main causes of such induced voltages in the shield are: time-varying magnetic flux and potential difference at the cable connections with the earthing system. It has been shown in that both components of the voltage along shield, due to ground potential difference and field coupling, are significant and moreover that they cancel each other. As a consequence, it is possible to optimize the d...

Dual polarization is a typical operational mode of polarimetric synthetic aperture radar (SAR). However, few studies have considered the scattering mechanism extraction of dual-polarization SARs. A modified Cloude-Pottier decomposition is proposed to investigate the performance of the scattering mechanism extraction of dual-polarization SARs. It is theoretically demonstrated that only HH-VV SAR...

In Übereinstimmung mit der vorangegangenen, theoretischen Ableitung hängen der Widerstand (R0) und die Stromspannungs [i-E) -Kurven von Mikropipetten, die als Elektroden in der Elektrophysiologie verwendet werden, vom Radius r0[cm] und der Konzentration c[Äq./cm 3] des Elektro­ lyten ab. Große Werte von r0 c [Äq./cm2] entsprechen Volumenleitung in der Öffnung. /?0vol ^ 1/ r0 c Abb. 3; die i-£-K...

A specially designed hemispherical deflector analyzer (HDA) with 5-element input lens having a movable entry position R0 suitable for electron energy analysis in atomic collisions was constructed and tested. The energy resolution of the HDA was experimentally determined for three different entry positions R0 = 84, 100, 112 mm as a function of the nominal entry potential V(R0) under pre-retardat...

This paper presents a mathematical model of the HIV/AIDS epidemic in Kunming, the provincial capital of Yunnan, China. The population is divided into several groups, with individuals possibly changing group. Two transmission routes of HIV are considered: needle sharing between injecting drug users (IDUs) and commercial sex between female sex worker (FSWs) and clients. The model includes male ID...
