The present aim of this study is to investigate the effect of different parameters influencing pounding in highway bridges. Pounding is the result of a collision between two parts of the deck and/or the deck and abutments at the separation distance during the earthquake.  In the present study, the period ratio of the adjacent frames, ground motion spatial variation, and soil-structure interacti...

Low-carbon economic development is at the heart of post-pandemic green recovery scheme worldwide. It requires without compromising on environment, implying a critical role that productivity plays in achieving carbon neutrality goal. Green measures quality growth with consideration for energy consumption and environmental pollution. This study employs slacks-based measure directional distance fu...

this paper proposes a control strategy for a cable-suspended robot based on sliding mode approach (smc) which is faced to external disturbances and parametric uncertainties. this control algorithm is based on lyapunov technique which is able to provide the stability of the end-effecter during tracking a desired path with an acceptable precision. the main contribution of the paper is to calculat...

1. introduction one of the main characteristics of azadegan plain in the west of khuzestan province is active instability of geomorphic features of karkheh river this instability caused extensive variations in the sedimentary setup in the western parts of this plain, such as buried and abandoned river beds, which are repeated over time. therefore, these variations should be studied in more deta...

COVID-19 has seriously threatened people’s health and well-being across the globe since it was first reported in Wuhan, China late 2019. This study investigates mechanism of transmission different periods within between cities to better understand nature outbreak. We use Moran’s I, a measure spatial autocorrelation, examine dependency dynamic autoregressive model explore mechanism. find that de...

the present study seeks to investigate users’ perception and evaluation of the function of designed environments and highlights a deeper understanding of man-environment relationship. the study tries to answer the question: “is there any relationship between the physical features of environment and users’ perception and evaluation of the environment and their spatial behaviors?” such investigat...
