abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...

In the present paper, the focus is on the evaluation of steel dual-system frame buildings using four main types of structural analysis (Linear Static, Linear Dynamic, Nonlinear Static and Nonlinear Dynamic Analyses) with regard to "Seismic Rehabilitation Code for Existing Buildings in Iran" (based on FEMA 273 and 356) where the first two authors of the article tend to follow the previous work (...

Introduction: The present study evaluates reliability of functional balance assessment tests in children aged 7-10 and its correlation with selected anthropometric parameters. Methodology: Population of the study includes 80 students aged 7-10 (40 female and 40 male). The Sharpened Romberg Test was used for static balance, while timed up and go test, Tandem walk test, and Y test were used for ...
