✦ Synopsis

Using an established finite-element simulation software suite developed in Tianjin, the authors analysed some factors which influenced the sensing field of an electrical resistance tomography (ERT) system. In order to improve the space evenness of the sensing field and 'focus' its effective measurement space, the authors described a guard electrode scheme, which improved both the quality of the reconstructed image and the delineation of conductive regions within the vessel.

Microdisk electrode arrays constitute an interesting tool for electroanalysis and electrocatalysis due to their increased sensitivity and excellent limits of detection. We first demonstrate that a 2-dimensional simulation based on the diffusion domain approximation can be used to simulate the respon

In this paper, an adapti¨e array algorithm is presented to minimize linear crosstalk in high-speed WDM systems. The algorithm is based on the optimum and the decision-directed algorithm added to the test signal sequences and sampling process. In transmitting data, the speed of algorithm processing r
