Prediction of mechanical properties of carbon nanotube-based composite is one of the important issues which should be addressed reasonably. A proper modeling approach is a multi-scale technique starting from nano scale and lasting to macro scale passing in-between scales of micro and meso. The main goal of this research is to develop a multi-scale modeling approach to extract mechanical propert...

This paper introduces a multi-rate hidden Markov model (multi-rate HMM) for multi-scale stochastic modeling of non-stationary processes. The multi-rate HMM decomposes the process variability into scale-based components, and characterizes both the intra-scale temporal evolution of the process and the inter-scale interactions. Scales are organized in a hierarchical manner from coarser scales to f...

INTRODUCTION Stroke is recognized as the third cause of mortality after cardiovascular and cancer diseases, so that lead to death of about 5 million people, annually. There are several scales to early prediction of at risk patients and decreasing the rate of mortality by transferring them to the stroke center. In the present study, the accuracy of Cincinnati pre-hospital stroke scale was assess...

Landscape metrics are widely used in landscape planning and land use management. Understanding how respond with scales can provide more accurate prediction information; however, ignoring the interference of multi-scale interaction may lead to a severe systemic bias. In this study, we quantitatively analyzed scaling sensitivity based on predict their optimal scale ranges. Using big data method, ...

objective: the purpose of this study was to investigate on relationship between spiritual intelligence, resilience, and perceived stress. methods: the study sample consisted of 307 students of sistan and baluchistan university. the connor– davidson resilience scale (cd-risc), the spiritual intelligence self-report inventory (sisri) and the perceived stress scale (pss) are used as a research ins...

objective: the purpose of this research was to investigate the role of the media, perfectionism, and difficulties in emotion regulation in prediction of muscle dysmorphia symptoms.  methods: in this research, 240 male body-builders were selected from five gyms in gorgan (north of iran). they were required to answer muscle dysmorphia disorder inventory (mddi), multidimensional perfectionism scal...

a nonlocal beam model based on the bernoulli–euler beam theory is presented to investigate the dynamic stability of embedded single-walled carbon nanotubes (swcnts) in thermal environment under combined static and periodic axial loads. the dynamic stability analysis is carried out by including the effects of small-scale parameter, temperature change and elastic medium. the equation of motion is...
