In a no-bend orthogonal drawing of a plane graph, each vertex is drawn as a point and each edge is drawn as a single horizontal or vertical line segment. A planar graph is said to have a no-bend orthogonal drawing if at least one of its plane embeddings has a no-bend orthogonal drawing. Every series-parallel graph is planar. In this paper we give a linear-time algorithm to examine whether a ser...

The stability in the operation of insulated gate bipolar transistor (IGBT) modules plays a crucial role wind power generation. It is essential to improve thermal performance heat sink IGBT converters and reduce consumption liquid cooling systems, order optimize dissipation converters. In this paper, simulation model liquid-cooled module established three different series flow channel structures...

s Normal mode Rossby waves are simulated with an efficient Double Fourier Series (DFS) spectral model, and their structures are investigated by the Empirical Orthogonal Function (EOF) analysis. By selecting appropriately the wave-vector component for EOF analysis among the geopotential height and velocity fields of wavenumber one, it was possible to get the EOFs from the time series data whose ...

Applying the theorems of Mobius inverse and Dirichlet inverse, a general algorithm to obtain biorthogonal functions based on generalized Fourier series analysis is introduced. In the algorithm, the orthogonal function can be not only Fourier or Legendre series, but also can be any one of all orthogonal function systems. These kinds of biorthogonal function sets are used as scramble signals to c...
