Algebraic decoding of the (23,12,7) Golay code (Corresp.)

Abstract: It is shown that the algebraic method for decoding three-error-correcting BCH codes is also applicable to complete decoding of the (23,12,7) Golay code.

Scaling behaviour for the water transport in nanoconfined geometries.

Abstract: The transport of water in nanoconfined geometries is different from bulk phase and has tremendous implications in nanotechnology and biotechnology. Here molecular dynamics is used to compute the self-diffusion coefficient D of water within nanopores, around nanoparticles, carbon nanotubes and proteins. For almost 60 different cases, D is found to scale linearly with the sole parameter θ as D(θ) = D(B)[1+(D(C)/D(B)-1)θ], with DB and DC the bulk and totally confined diffusion of water, respectively. The parameter θ is primarily influenced by geometry and represents the ratio between the confined and total water volumes. The D(θ) relationship is interpreted within the thermodynamics of supercooled water. As an example, such relationship is shown to accurately predict the relaxometric response of contrast agents for magnetic resonance imaging. The D(θ) relationship can help in interpreting the transport of water molecules under nanoconfined conditions and tailoring nanostructures with precise modulation of water mobility.

An efficient approach to noise analysis through multidimensional physics-based models

Abstract: The paper presents a general approach to numerically simulate the noise behavior of bipolar solid-state electron devices through a physics-based multidimensional device model. The proposed technique accounts for noise sources due to carrier velocity and population fluctuations. The power and correlation spectra of the external current or voltage fluctuations are evaluated through a Green's function, linear perturbation theory equivalent to the classical Impedance Field Method for noise analysis and its generalizations. The numerical implementation of the method is performed through an efficient technique, which allows noise analysis to be carried out with negligible overhead with respect to the small-signal simulation. Some case studies are analyzed in order to compare the present approach with theoretical results from the classical noise theory of p-n junctions and bipolar transistors.

Synthetic function analysis of large printed structures: the solution space sampling approach

Abstract: This work proposes an algorithm based on the numerical definition of entire domain basis functions to be used in the full-wave method of moments (MoM) solution for large printed antennas. After a block partitioning of the structure, entire domain basis functions are generated and then employed in the global solution process. The generation algorithm and a possible selection model is presented in detail. The method permits a strong reduction of memory occupation and computation time. A numerical example for a 4 /spl times/ 2 array of stacked patches is presented.
