Abstract: A five-point non-stationary interpolating scheme is proposed in this paper. The limit curve of the scheme is C1. The scheme can reproduce all original function curves spanned by exactly. Comparison experiments are also given to better demonstrate it.

Abstract: This paper presents an inclinometer-based deflection curve reproduction system which can reconstruct the deflected shapes of bridges directly. Because the conventional deflection-measuring methods are performed by collecting the deflection data at just a few discrete points along the bridges, the bridges’ deflected curves are not smooth enough. The operation of the proposed system is performed by utilizing the displacement transducer to determine the measuring intervals, using inclinometer to collect the angles of the measured points, calculating the deflection values, further applying Gradient Mean Prediction Filtering (GMPF) algorithm to filter the deflection data, and finally reproducing the deflection curves of bridges. The precision, feasibility, reliability, and effectiveness are verified by laboratory tests and field applications.

Abstract: Growth and reproduction of Porphyra kuniedae from the southern coast of Korea were investigated. Biomass, plant size and occurrence of reproductive structures were monitored every other week from November 2001 to March 2002. Release of zygotospores and monospores from the plants was induced and the number of spores was counted in the laboratory culture every month. Biomass and plant size were found to be inversely correlated with water temperature. The maximum values in biomass and plant size were observed in mid-January with the lowest water temperature, and the values decreased with the increase of water temperature. Based on the cohort analysis, three cohorts started in late November, one to two cohorts were added every other week, and the maximum was eight in mid-January. The percentage of matured plants in the field was the highest in January. In the laboratory culture test, zygotospores were released more than monospores from large plants in late December while monospores were released much more than zygotospores since late January.

Abstract: Image halftoning is the core technique of digital image output, which determines the quality of the color and tonal gradation reproduction. In this paper, the existing halftoning techniques were analyzed and evaluated, such as FM halftoning and AM halftoning, etc. And a new halftoning mode, frequency conversion amplitude modulation (FCAM), was proposed. This method is still based on AM halftoning, but it uses the different screen frequency for halftoning image of the different color version, so as to avoid moiré fringes on the smaller superposition angle. The use of new halftoning model can achieve halftoning image output which is more than 4 colors (such as 6 colors or 7 colors) without visual moirè pattern when overprinting. By the new technique, high-fidelity printing is achieved, and the color gamut of the output image is expanded, and we can get more vivid realistic effect of image transmission. We tested color gamut expansion of 6 colors and 7 colors high-fidelity printing, and obtained the expected conclusion by quantitative analysis.

Abstract: With the rapid development of the economy, the automotive industry and road transport have also been rapidly developed. Road traffic accidents occur frequently, which not only brings a lot of inconvenience to road traffic management but also threatens people's lives and property. In many road accidents, vehicle collisions are the most serious and dangerous also the largest. So having a comprehensive, systematic study of the car's collision is becoming the world's most pressing subject. The whole process of the collision of moving vehicle is inseparable from the role of the force. So in order to better analyze vehicle collisions and reproduce this process, a lot of mechanical knowledge should be required. This paper studies the vehicle accident reconstruction mechanical problems, laying the foundation of further research.
