Based on only MSP430F169 chip, a digital chaotic generator for a grid-like JERK chaotic system is designed, from which grid-like [Formula: see text] chaotic attractors are generated. By analyzing the nonlinear functions of the gird-like chaotic system, the saddle focal balance points are respectively extended in [Formula: see text],[Formula: see text] direction. According to the hardware requirements of MSP430F169 chip, using Euler algorithm to discretize the chaotic system, the values of 36 saddle focal balance points need to be recalculated. The numerical values of the focal balance points which are involving iterative operations are given by the proposed comparative piece-wise method, their analysis and numerical simulations are also performed. The software and hardware design ideas are given for implementation, the experiment results are verification of the feasibility of the scheme.

Traditional fighter electrical boxes detection system can not be efficient and accurate implementation in detecting electrical boxes, in order to achieve accurate detection of the electrical box, this paper had designed a detection device consists of upper machine and lower machine system. The system is based on the C8051F120 single chip microcomputer as the core. It is controlled by a machine on and off of the FPGA to drive the relay array to detect the safety status of electric box, through the communication between upper machine and lower machine to display the measurement results. The integrated test system can detect various fighter electrical control boxes, which overcomes the shortcoming of a test equipment in the past can only test a class of products, improves test accuracy and efficiency.

At present, the college English testing system has become an indispensable system in many universities. However, the English test system is not highly humanized due to problems such as unreasonable framework structure. This paper combines data mining technology to build a college English test framework. The college English test system software based on data mining mainly realizes the computer program to automatically generate test papers, set the test time to automatically judge the test takers’ test results, and give out results on the spot. The test takers log in to complete the test through the test system software. The examination system software solves the functions of printing test papers, arranging invigilation classrooms, invigilating teachers, invigilating process, collecting test papers, scoring and analyzing test papers in traditional examinations. Finally, this paper analyzes the performance of this paper through experimental research. The research results show that the system constructed in this paper has certain practical effects.

Abstract There are growing efforts to mine public and common-sense semantic network databases for engineering design ideation stimuli. However, there is still a lack of design ideation aids based on semantic network databases that are specialized in engineering or technology-based knowledge. In this study, we present a new methodology of using the Technology Semantic Network (TechNet) to stimulate idea generation in engineering design. The core of the methodology is to guide the inference of new technical concepts in the white space surrounding a focal design domain according to their semantic distance in the large TechNet, for potential syntheses into new design ideas. We demonstrate the effectiveness in general, and use strategies and ideation outcome implications of the methodology via a case study of flying car design idea generation.
