Investigating the occurrence of defects in structures is currently a major issue significant interest. In this paper, we present experimental research findings on relationship between moments power spectrum and presence damage bridge beam structures. The study based analysing random oscillation signal structure under effect displacement loads. results demonstrate that value spectral moment sens...

in this research a new approach is proposed for elasto-plastic analysis of structures with truss elements. this method covers both perfectly plastic and hardening properties. the proposed technique uses substituting virtual loads instead of modifying the stiffness matrix. to solve this kind of problems, complementary programming is utilized. numerical examples demonstrate that elastoplastic ana...

background: work-related musculoskeletal disorders (wmsds) are a leading cause of disability and workers compensations. objectives: the research was done in tehran pars-electric factory to prevent inducing wmsds. rapid entire body assessment (reba) was carried out to assess musculoskeletal loads on workers due to their postures, repetition, and force. nordic musculoskeletal questionnaire (nmq) ...

Due to the growth of renewable resources in electrical power systems, it is essential study and analyze possible events that impact safety system. One these abnormal islanding distributed generators. The consists an isolated operation generators their respective loads, hence, part system disconnected from utility, but still operation. This can bring numerous negative consequences: both for elec...

Distributed energy resources and demand-response initiatives are expected to increase the flexibility of future power systems. This paper presents new models individual photovoltaic systems, batteries, thermostatically controlled loads that can be used propose validate coordination schemes. Unlike previous works focus on aggregate representations, these make it possible represent more accuratel...

in this paper, the mean value of strain energy density criterion has been used to predict the critical fracture load in specimens with u-shaped notch under bending loads. an equation for calculation of averaged strain energy density in this zone has been presented. bending loads under mode i have been considered. two cases have been studied: 1) the control volume only includes the semicircular ...

background: aub is a common cause of women’s referring to gynecologists. although hysteroscopy is known as the gold standard technique for diagnosing the cause of aub, sonohysterography is less invasive, and it is performed by general gynecologists. the purpose of this study was to evaluate the diagnostic performance of sonohysterography compared to the results of the endometrial biopsy, guided...

1.Introduction Following several methods of some past publications, among these we refined an important idea that related queries could be derived from queries submitted within the same session. As the browsers not just provide the previous queries but more informations,so we could use these informations to build a expert database for a special user, base on the database ,we could analysis some...

This paper presents an insole FSR (Force Sensing Resistor) to dynamically detect weight variations in an exoskeleton system. The proposed methodology is intended for tasks of lifting and lowering heavy weights with an industrial exoskeleton to substantially reduce spinal loads during these manual handling activities. Instead of extensively placing high-dense force sensors by covering the whole ...
