In this paper, Semantic Differential Method was introduced into design segmentation research based on the theory of market segmentation and Kansei engineering, so as to quantitatively study on the measurement of aesthetic differentiation among consumer groups, and discuss related strategies of product design. Through empirical research, the corresponding relationship between consumer groups and Kansei...
As a nascent method of multi-criteria decision-making with uncertainty, DS/AHP is similar to the analytic hierarchy process (AHP) in structure and its analytic processes are based on Dempster-Shafer (DS) theory. However, it is unsuitable to deal with the multi-attribute decision making with incomplete information, especially the attributes with missing values. In this paper, a new method for multiple-attribute...
Diffractive optical elements (DOE) have the special property of minus dispersion which can be used in the optical system instead of lens to improve its performance, lighten its weight, and reduce its volume effectively. Based on a conventional refractive long-length objective, a lightweight Hybrid Diffractive - Refractive (HDR) long-length objective was designed with the CODE V software. The optical...
Wide-angle objective matched with detector can be used for measuring the field of view of sight mirror. In order to obtain the system with good image quality and lightweight, diffractive optical elements are employed for the improvement of their image quality and the reduction of the used element number and the system weight. In this paper, a wide-angle objective was designed. Its optical parameters...
Based on broadband communication technology, this system has solved the problem of remote data acquisition and image monitoring of distribution transformers, realizing timely alarm, real-time data acquisition and timely load detection. By combination of analog image acquisition and digital image processing, we can receive both high-quality initial image data and high-quality storage images from monitoring...
Based on actual problems in power industry, a power quality on-line monitoring system was set up by comprehensively adopting embedded technology of software and hardware platform, GIS (Geographic Information System) information technology and Internet technology. Meanwhile analyzing methods of time domain, frequency domain and mixed domain were used in this system to monitor, evaluate and analyze...
ZYQ-11S/12S voltage switching boxes are important components of PXH-831/801E protection screen. Bus P.T secondary alternating voltage at I and II sections of power substation will be switched in the box and then transmitted to corresponding protective devices. The author has analyzed carefully on several failures under special operating conditions of ZYQ-11S/12S voltage switching boxes. Lay out every...
The independent innovation capability is the key factor that affects the sustainable development of automobile industry. By analyzing the concept of independent innovation capability and considering the traits of automobile industry, an indicator system of independent innovation capability for automobile industry is constructed on the basis of extensive investigation. While the qualitative and quantitative...
The use of two deformable mirrors (DM) with finite conjugate ranges is studied for compensating amplitude and phase distortions due to laser propagation through turbulence atmosphere. The Strehl ratio versus the log-amplitude variance (also known as the Rytov parameter) and the conjugate range of the second deformable mirror are plotted. The conclusion is drawn that an adaptive optics transmitting...
