These articles discuss Earth's many dynamic processes and their interactions.
One of the most interesting findings of hypertension research in the past 10 years has been that the cardiovascular protective effects of antihypertensive drugs depend not only on the mean blood pressure (BP) values achieved during treatment but also on the consistency of BP control between on-treatment visits. This was suggested in 2007 by the observation that in patients with hypertension and...

The locomotive assignment and the freight train scheduling are important problems in railway transportation. Freight cars are coupled to form a freight rake. The freight rake becomes a train when a locomotive is coupled to it. The locomotive assignment problem assigns locomotives to a set of freight rakes in a way that, with minimum locomotive deadheading time, rake coupling delay and locomotiv...
Railway scheduling is a complex task of rail operators that involves the generation of a conflict-free train timetable. This paper presents a discrete-event simulation-based optimization approach for solving the train timetabling problem to minimize total weighted unplanned stop time in a hybrid single and double track railway networks. The designed simulation model is used as a platform for ge...
Support Vector Machine (SVM) is one of the important classification techniques, has been recently attracted by many of the researchers. However, there are some limitations for this approach. Determining the hyperplane that distinguishes classes with the maximum margin and calculating the position of each point (train data) in SVM linear classifier can be interpreted as computing a data membersh...
Background: one of the most essential components in patient- physician relationship is the length of visit. Short time visit can affect visit quality and patient- physician relationship. This study aimed at comparing specialists visit length with standards in general hospitals of Qazvin. Materials and Methods: This cross-sectional study conducted in general hospitals of Qazvin in 2013. 428 ...
train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. on the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. first, we propose a fuzzy energy ...
