A combination of ion exchange and membrane extraction successfully recovered cadmium and cyanide from simulated cadmium-cyanide rinsewaters. The ion exchange loading was most effective at cyanidetocadmium molar ratios of 4:l or less; when the molar ratio exceeded 4:1, cadmiumcyanlde complexes caused a chromatographic displacement of free cyanide from the resin. Cyanide-to-cadmium molar ratios i...

We simulated the remagnetization dynamics of the ultra-dense and ultra-thin magnetic dot array system with dipole-dipole and exchange coupling interactions. Within the proposed 2D XY superlattice model, the square dots are modeled by the spatially modulated exchange-couplings. The dipole-dipole interactions were approximated by the hierarchical sums and dynamics was reduced to damping term of t...

We provide exact analytical expressions for the magnetic susceptibility function in the high temperature expansion for finite Heisenberg spin systems with an arbitrary coupling matrix, arbitrary single-spin quantum number, and arbitrary number of spins. The results can be used to determine unknown exchange parameters from zero-field magnetic susceptibility measurements without diagonalizing the...

In this note we show how the main result of Lou et al. [2] can be generalized to an unreliable machine with various quality levels. We consider a single machine which can process parts of di erent types. The machine can process at most one part at a time and it needs a setup period whenever it switches from one part-type to another. Parts enter the system in type-speci c input rates and require...

AbstractAn EMI Camera LSI (EMcam) with a 12 x 4 on-chip 250μm x 50μm loop antenna matrix in 65nm CMOS is developed. EMcam achieves both the 2D electric scanning and 60μm-level spatial precision for the first time. The down-conversion architecture increases the bandwidth of EMcam and enables the measurement of EMI spectrum. Shared IF block scheme is proposed to alleviate the increasing power and...

We extend a reciprocity theorem of Stanley about enumeration of integer points in polyhedral cones when one exchanges strict and weak inequalities. The proof highlights the roles played by Cohen–Macaulayness and canonical modules. The extension raises the issue of whether a Cohen–Macaulay complex of dimension d embedded piecewise-linearly in R is necessarily a d-ball. This is observed to be tru...

The advancement in technology has brought a new era in terrorism where Online Social Networks (OSNs) have become a major platform of communication with wide range of usage from message channeling to propaganda and recruitment of new followers in terrorist groups. Meanwhile, during the terrorist attacks people use OSNs for information exchange, mobilizing and uniting and raising money for the vi...

This paper performs tests on several different foreign exchange series using a methodology inspired by technical trading rules. Moving average based rules are used as specification tests on the process for foreign exchange rates. Several models for regime shifts and persistent trends are simulated and compared with results from the actual series. The results show that these simple models can no...

The Single Variable Exchange algorithm is based on a simple idea; any model that can be simulated can be estimated by producing draws from the posterior distribution. We build on this simple idea by framing the Exchange algorithm as a mixture of Metropolis transition kernels and propose strategies that automatically select the more efficient transition kernels. In this manner we achieve signifi...

With the ongoing process of building business networks in today’s economy, businessto-business integration (B2B Integration) has become a strategic tool for utilizing and optimizing information exchange between business partners. Industry and academia have made remarkable progress in implementing and conceptualizing different kinds of electronic intercompany relationships in the last years. Nev...
