We investigate leading twist transverse momentum dependent origins of transverse spin asymmetries in hadron-hadron collisions. The chiral-odd T-odd distribution function with intrinsic transverse momentum dependence, which would signal an intrinsic handedness of quarks inside a hadron, could account for single spin asymmetries and at the same time for the large cos 2φ asymmetry in the unpolariz...

the prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. this has motivated researchers to develop cognitive radio (cr) as a smart and dynamic radio access promised solution. a major challenge to this new technology is how to make fair assignment of available spectrum to unlicensed users, particularly for smart grids communication. this paper introduces an i...

In this paper we introduce an abstract data type for the distributed representation and eecient handling of sparse grids on parallel architectures. The new data layout, implemented by means of the PVM message passing library, provides partitioning and dynamic load balancing transparent to the application making use of it. This enables parallelization of sequential partial diierential equations ...

The packet routing problem plays an essential role in communication networks. It involves how to transfer data from some origins to some destinations within a reasonable amount of time. In the (`, k)routing problem, each node can send at most ` packets and receive at most k packets. Permutation routing is the particular case ` = k = 1. In the r-central routing problem, all nodes at distance at ...

The East China Power Grid (ECPG) is the biggest regional power grid in China. It has the biggest installed capacity of pumped storage power plants (PSPPs) and is responsible to coordinate the operation of its five provincial power grids. A recent challenge of coordinating operations is using PSPPs to absorb surplus energy during off-peak periods and generate power during peak periods. Differing...

The work presented in this paper employs multiscale subspace grids for pattern recognition applications. The proposed approach addresses the curse of dimensionality problem often associated with this task. The paper uses a multi-scale approach where coarse scale, being stable and generic in nature, suits well for small sample sizes, and fine scales, being more specialized in nature, enhance cla...

Convergence of multigrid and defect-correction iterations is comprehensively studied within different incompressible and compressible inviscid regimes on high-density grids. Good smoothing properties of the defectcorrection relaxation have been shown using both a modified Fourier analysis and a more general idealizedcoarse-grid analysis. Single-grid defect correction alone has some slowly conve...

The variation of inductance with frequency in high performance power distribution grids is discussed in this paper. The impedance characteristics of the power grid need to be well understood for the design of efficient and robust high performance power distribution grids. The physical mechanisms underlying the dependence of inductance on frequency are discussed. The variation of inductance with...

In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4),  ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...

The mathematical model of a piezoelectric transformer the transverse-transverse type and describes method its construction has been presented. Although modeling programs for devices can achieve any predetermined accuracy, simulation results cannot be directly used in development electronic equipment, because are not integrated with CADs, this reason most often calculations circuits based on pie...
