This paper uses a PSOPC model based non-destructive damage identification procedure using frequency and modal data. The objective function formulation for the minimization problem is based on the frequency changes. The method is demonstrated by using a cantilever beam, four-bay plane truss and two-bay two-story plane frame with different scenarios. In this study, the modal data are provided nume...

background: currently, orofacial sequelae are recognized as very influential on the qualityof- life for a victim of orofacial damage. therefore, correct forensic assessment for indenisation purposes is mandatory. however, orofacial damage is frequently reduced to organic components, which results in a forensic assessment process, which are inadequate. this study aims to improve the orofacial da...

in this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in euler-bernoulli beams are assessed. static response of a beam is obtained using the finite element modeling. in order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...

this paper presents new sensitivity-based methods for detection of structural damage using incomplete noisy modal data. these methods are based on the first-order derivative of modal parameters. changes of natural frequency do not usually provide spatial information on the structural damage. they are also not sensitive to the local damage. in this paper, a new sensitivity function is proposed u...

introduction: according to the high incidence of bell's palsy (ifp) and lack of clinical data regarding different aspects of disease, the present study investigated 121 iranian patients with peripheral facial paralysis referred to the emergency department. methods: in this retrospective study, all patients with peripheral facial paralysis, referred to the emergency department of poursina hospit...

premenstrual syndrome is a common disorder experienced by up to 50% of women during reproductive age. the prevalence of severe form of pms (pmdd) is 3% to 8 %. psychiatric disorders in pms patients have resulted in significant morbidity and in some cases caused resistance to the treatment process.390 participants (264 with pms/pmdd, and 126 healthy students of university of guilan) who complete...

the aim of this study was to investigate c-reactive protein (crp) level in preeclampsia (pe) and its association with the severity of the disease. this cross-sectional study included 43 women with mild pe, 43 women with severe pe, and 43 healthy pregnant. they were selected in the third trimester of pregnancy in the afzalipour hospital, kerman, iran, from march 2006 to march 2007. mean diastoli...
