The paper deals with applications of interval analysis methods to a special practical problem of parameter identification of a real chemical catalytic process. Several possible models of the process are given. The measured data of the process are corrupted by both usual fluctuation errors and chaotic disturbances. Samples of the input information are short. Any characteristics (including probab...

Various studies have reported the effect of severe malnutrition on electrolyte levels and electrocardiographic parameters. However, only a few have reported these findings in mild and moderate grades of malnutrition in children. Therefore, the objective of this study was to assess the effect of malnutrition (mainly mild and moderate grades) on corrected QT interval (QTc) and QT dispersion (QTcd...

Abstract Uncertainties are unavoidable in practical engineering, and phononic crystals no exception. In this paper, the uncertainties treated as interval parameters, an crystal beam model is established. A perturbation-based finite element method (P-IFEM) affine-based (A-IFEM) proposed to study dynamic response of beam, based on which vibration transmission analysis can be easily implemented sa...

In this paper, we define Some domination parameters on IVIFG and derive some relations and then verify by using Interval valued intuitionistic fuzzy graphs and discussed some properties. Also, we introduced Immoderate semi-complete IVIFG and its properties.

background : identifying the sources of variation in qtc measurements is important for preventing arrhythmias during and after hemodialysis. the present study was designed to determine the correlation between the type of hemodialysis buffer and the changes in qtc interval in patients on chronic hemodialysis.   methods: fifty-nine patients on chronic hemodialysis who referred in winter 2007 to h...
