This study deals with predicting nonlinear time history deflection of scallop domes subject to earthquake loading employing neural network technique. Scallop domes have alternate ridged and grooves that radiate from the centre. There are two main types of scallop domes, lattice and continuous, which the latticed type of scallop domes is considered in the present paper. Due to the large number o...

introduction: exercise training increases skeletal muscle capillary density, but the molecular mechanisms of this process are not yet clear. the aim of the present study was to investigate the effect of acute long- term submaximal exercise on serum vascular endothelial growth factor (vegf) as the main angiogenic factor, and matrix metalloproteinases 2 and 9 ( mmp-2 and mmp-9), as the degrading ...

In order to study the impact on China-Europe freight trains when three main passages including Alashankou Port (Khorgos), Manzhouli, and Erenhot were attacked, Count running routes of trains, make into an adjacency matrix, calculate changes network average degree, isolated node ratio, efficiency, distance under background interruption channels analyze trains. The train operation, research shows...

Abstract The electric power industry is going through a relatively large transformation period of energy development, and new equipment such as distributed supply has emerged the times require. However, there often problem insufficient coordination between grid frame in main distribution network. This paper starts with two stakeholders, namely, generation operator system operator, to build two-...

Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...

Providing a fresh and cool airflow in underground mines is one of the main concerns during mining. Destruction of support systems, the presence of undesirable objects in the airway and distortion of airflow are the parameters involved that would result in pressure loss, which would affect the ventilation network. There are a lot of research works about the ventilation network planning that cons...
