objective: oral health is one of the basic components of preschool children's health. young children completely depend on their parents, specially their mothers, to have an appropriate oral health. health belief model shows the relationship between some structures related to personal perceptions, barriers and perceived self-efficiency, and behavior. this study aims to determine the oral he...

This paper presents a newly developed hybrid simulation technique for coupled structural-acoustic analysis, which applies a wave based model for the acoustic cavity and a modally reduced finite element model for the structural part. The resulting hybrid model benefits from the computational efficiency of the wave based method, while retaining the finite element method’s ability to model the str...

A comparative study of vibration and acoustic noise reductions via electronic switching controls for switched reluctance motor (SRM) is presented. First, studies concerning the acoustic noise and vibration sources, their effects and the existing mitigation approaches are given. Then five switching control approaches, which belong to the magnetic and electronic remedies, are proposed and applied...

conclusions reduction of surplus production factors through comprehensive planning based on the results of the data envelopment analysis can play a major role in cost reduction of hospitals and health sectors. in hospitals with a technical efficiency score of less than one, the original and projected values of inputs were different; resulting in a surplus. hence, these hospitals should reduce t...
