We propose a multi-point correction method to design a CMOS current-mode function with high input dynamic range. The dynamic range is dependent on the number of correcting circuits. Consider the accuracy, we can properly select the turn-on current in the correcting circuit. The exponential circuit for a design example, equipped with six correcting circuits, has a linearity of 39.5dB for linearity...
We propose a multi-segment approximation method to design a CMOS current-mode hyperbolic tangent sigmoid function with high accuracy and wide input dynamic range. The dynamic range is dependent on the number of segments and the accuracy is related to the dividing point. From mathematical results, we can observe the proposed method outperforms traditional methods. We implement the multi-segment approximation...
Based on the kind of phenomenon that the research of the rural travel characters almost blank, this paper focus on the travel features of the Dafeng city rural residents, it builds the quality evaluation index system of the travelling of the Dafeng city rural resident from four aspects which include: travel destination is accessibility, Travel road is comfortable, travel facilities are perfective,...
It is convenient and useful to use the Monte Carlo simulation (MCS) in project schedule management, but at the same time, it provides very few management indexes for schedule risk analysis. Therefore, based on PERT network assumption, the shortcomings of current construction schedule management indexes are summarized and new construction schedule management index is put forward to calculate the criticality...
The novel decoration was used at urban tracks and traffic line, overhead roads, railway roads, cloverleaf intersections, cooling towers, outdoors high voltage direct current converter stations, and concrete mixing sites and so on. And it can conduct sound-shielding function by sucking in sound, isolating sound, and eliminating sound to equipment like diesel engines, generators, electric motors, freezers,...
This paper develops a robust image watermarking algorithm based on Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT). With the use of masking peculiarity of human visual system, we firstly decompose host image through the three-layer wavelet, and secondly embed the watermark image into the lowest approximation components of the gray image according to the Discrete Cosine Transform...
