A bit full adder is a very important component in the digital system. Design of a full-adder circuit, as an example, by changing its output function expression in the form of expression, use the gates, decoder, multiplexer etc 74 series devices, the eight circuits realization form are given respectively, and briefly analyzed the advantages and disadvantages of the various circuit implementation. The example show that the design of combinational logic circuits has mobility and variety, it could give the instructiveness and the guiding for other design of combinational logic circuits.

Steam-exploded cotton stalk was used as raw material in ethanol production through simultaneous saccharification and fermentation by Penicillium Q59 and Saccharomyces cerevisiae P1. The fermentative conditions were firstly examined by single factor experiments to determine the central point in Box-Behnken design, which was explored with expectation to get optimized fermentative conditions for enhancement of ethanol production. The results of optimized fermentative conditions were determined as follows: fermentation time was 10.5 days, bran added percent was 15%, initial pH value was 5.5. Under the optimal conditions, the experimental yield of ethanol was 99.85 ± 4.21 g·kg-1SECS (steam-exploded cotton stalk), which was close to the theoretical predicting value, it showed the model was feasible. The research results will provide technical reference for further exploitation of cotton stalk.

Based on the study of fish lateral line sensing mechanism, integrated fluid dynamics, boundary layer theory, coupling theory and so on. To establish a neural network model similar to the fish neuromas model. After the numerical calculation and simulation analysis to simulate fish lateral line system, we can get the conclusions to apply to autonomous underwater vehicle (AUV) navigation and target recognition. Provided a new method for AUV navigation and environment perception. Computer simulation results presented that based on the fish lateral line sensing mechanism to build a perception model, AUV can identify a new water condition distinguishably. This discovery can be used in navigation and positioning of AUV.

The development of computational thinking ability is an important part of college computer education domestically and overseas. It is a new direction and goal of college computer language teaching reform and construction. Based on computational thinking combined with teaching experience, this paper introduces a new teaching model for college VB programming courses, which adopts modularization and case teaching project.

A prototype of video detection system applied to traffic flow inspection is developed, which uses CMOS linear image sensor with high resolution 2K pixels and wide dynamic range as the core of imaging device. It combines FPGA with DSP as the core of acquisition and processing of massive image data. Moreover, a novel multiscale and hierarchical clustering algorithm for image segmentation is presented. Based on the theory of graph spectral, the algorithm can construct a new graph by analyzing the feature of an original image at different clustering scales, so that image segmentation can be accomplished easily to segment the image. The simulation results show that the row scan speed of this system can reach to 1000 lines per second, the resolution being 2048 pixels.
