Image registration is a key operation to spatially align two or more images for comparing the difference between them or exploiting complementary information from those images. The main objective regarding automatic registration of satellite images is to obtain an accurate set of tie points and then apply the transformation function which is most suitable to the pair of images to be registered....

With the continuous increase in proportion, renewable energy sources have brought great challenges to traditional protection based on fundamental frequency, due their complex short-circuit current characteristics which are different from synchronous generators. As main of tie line (outgoing line) station, differential will also be seriously affected terms its operation performance, and even fai...

The regional power system is an essential mechanism to solve the unbalanced distribution of resources and achieve more efficient resource allocation. In this paper, optimal scheduling model developed, maximize social welfare minimize clean energy electricity curtailment. This can realize allocation generation maximum accommodation multiple types energy, by minimizing sum purchase cost dynamic p...

Reservoir recovery processes involve complex mass and heat transfer between the injected fluid and the resident rock-fluid system. Thermal-compositional reservoir simulators can be used to plan such displacement processes, in which the phase behavior is computed with an Equation of State (EoS). These thermodynamic-equilibrium computations include phase-stability tests and flash calculations, an...

Strut and tie models consist of axial force members which react on one another and on external supports through nodes, i.e. they are trusses. An analysis of a truss problem is normally entered by reducing it to a line diagram of member centrelines representing the lines along which the stress resultants in the members are intended to act. When forces are concentrated in a line diagram the nodes...
