Abstract: In this paper, innovative design of printing-like effect digital jacquard fabric based on layered-combination design mode is introduced with proper design illustrations. Directly borrowed from layered design method of digital image and corresponding color theory, the innovative design method theoretically can be divided into colorless mode and colorful mode two parts. Following design method of full-color compound structure invented specially for layered-combination design mode, several colorless single-layer structures can be combined to form a full-color compound structure, which enables digital jacquard fabric to express printing-like effect with mega-level mixed colors. The results of study provided the possibility of opening creative horizon and aesthetical dimension for jacquard fabric design.

Abstract: SINS algorithm and its application have made rapid development. The application of hardware simulation of strap-down navigation algorithm consumes too highly and the research phase in the laboratory is difficult to achieve, so this paper adopts computer simulation to test the algorithm. This article firstly constructed a track simulator which provides the information of the inertia device (the force and angular velocity). The data gained from the simulator is the source of SINS algorithm. In this paper, a Graphical User Interface was designed .We can enter different parameters for different trajectory to test the Euler angle algorithm, direction cosine algorithm ,quaternion algorithm and rotary normal vector algorithm .This method is simple and flexible .

Abstract: Mass Customization (MC) has already become a main production mode of enterprises. In this production mode, enterprises can meet the requirement of individuals at the same price and time of delivery as mass production did. Parametrical rapid design is the key technology in realizing MC. The paper proposed a parametric design method based on database system and Solidworks API function, applying VC++ and Access, a parametric design application system based on Solidworks is developed. As an example, this method is applied to bearing part product, and the method is verified

Abstract: For the lack of the traditional calibration methods of the sensor static and dynamic characteristic parameters, the software of parameter calibration was designed by using the graphical programming language, that is, LabVIEW. The USB-based data acquisition card controlled by software is used to obtain the output voltage of the sensors, displaying a characteristic curve in the real time, and the static parameters (sensitivity, linearity, etc.) and dynamic parameters (natural frequency, damping ratio, etc.) were calculated and analyzed automatically on-line by using mathematical tools such as the least square fitting, spline interpolation, etc.. Experimental results show that the software has a good interface, is easy to operate, the results are accurate and efficient, which can fully meet the needs of industrial testing.Introduction

Abstract: In order to obtain good starting performance of the electric scooter driven by brushless permanent-magnet direct circuit motor(BLPMDCM)，modules of RMxprt and Maxwell 2D in Ansoft software are used to build finite element simulation model of BLPMDCM. We simulated and studied the basic features and starting process of BLPMDCM. The results of internal magnetic field distribution and dynamic performance simulation are obtained when the motors are in different positions. The results provide a theoretical basis to further optimize the design, improve the starting torque and reduce torque ripple for this new type of permanent magnet motor and its control system.

Abstract: Based on the spectral absorption/reflection principles, a home-made optic sensor which included substrate, filtration membrane, reaction film and absorbent pad has been proposed and established to detect vitamin C rapidly. In the experiment, ferric ion was reduced to ferrous ion by vitamin C in samples, the reaction film color turned from yellow to orange-red upon the binding reaction of ferrous ion to phenanthroline. Results demonstrated that vitamin C concentrations were proportional to L values of the L a b color system. A good linearity was presented in the range of 0.25-2500 μg/mL. The correlation coefficient(r) was 0.980 and the testing time was about 2 min at room temperature.

Abstract: Both the industrial sector and the academic study is the single-arc and double-arc gear at present, that is, tooth profile curve are composed by one or two arc. This paper propose a new arc gear —, which tooth profile curve are composed by four arcs, and gain a invent patent (patent number is 200810212732.1). Finite element analysis and tests conformed that qssuadruple-arc gear carrying capacity is more than 30% higher than double-arc gear. Tests also confirmed that quadruple-arc gears are smooth and have less noise compared with double-arc gears when running.

Abstract: MIR/NIR micro-imaging can supply not only the spectra information but also the spacial distribution information, which is superior to the traditional MIR/NIR spectroscopy analysis. The definition of near/min-infrared micro-imaging is one of the important factors which will influence the correctness of imaging result. In this thesis, two kinds of plastic film which were similar to each other in appearance were regarded as the research object, of which the MIR and NIR micro-images were collected. The raw compare correlation images, 2^nd derivative compare correlation images, raw chemimap images and 2^nd derivative chemimap images of the MIR/NIR micro-images of the two materials were studied respectively. The result indicated that not only can the preprocessing of 2^nd derivative enhance the discrimination of the spectra so as to enhance the image feature but also eliminate the nonuniformity of the compare correlation images. Both the MIR and NIR chemimap images will be inverted after the preprocessing of 2^nd derivative. This study will, to some extent, provide some reference to the manufacturing process quality inspection and control and rapid discrimination of the safety of agricultural products and food packaging and the imaging methods of MIR/NIR micro-image.
