The application of Han Dynasty cultural elements to modern product design
Chinese Han Culture, as Chinese nation's "core culture", is the cultural symbol of Chinese nation, and played an important role in the history of Chinese cultural development, even in the history of world cultural development. Designing in the Han Dynasty, while inheriting Chinese traditional culture, but also having its unique style, are appreciated and respected by the people nowadays. In a modern society where the design is becoming more diversified, the innovative design based on traditional culture and art has its unique charm and vitality. This paper presented our recent research on the application of Han Dynasty cultural elements to modern product design, reflected the local design connotation of Han Dynasty cultural elements
Non-Volatile Magnonic Logic Circuits Engineering
We propose a concept of magnetic logic circuits engineering, which takes an
advantage of magnetization as a computational state variable and exploits spin
waves for information transmission. The circuits consist of magneto-electric
cells connected via spin wave buses. We present the result of numerical
modeling showing the magneto-electric cell switching as a function of the
amplitude as well as the phase of the spin wave. The phase-dependent switching
makes it possible to engineer logic gates by exploiting spin wave buses as
passive logic elements providing a certain phase-shift to the propagating spin
waves. We present a library of logic gates consisting of magneto-electric cells
and spin wave buses providing 0 or p phase shifts. The utilization of phases in
addition to amplitudes is a powerful tool which let us construct logic circuits
with a fewer number of elements than required for CMOS technology. As an
example, we present the design of the magnonic Full Adder Circuit comprising
only 5 magneto-electric cells. The proposed concept may provide a route to more
functional wave-based logic circuitry with capabilities far beyond the limits
of the traditional transistor-based approach
Acoustic demands and influencing factors in facilities for the elderly
The aim of this study was to examine the characteristics of the elderly individuals’ acoustic demands and the effects of six influencing factors, categorized into the following three types: activity type, objective environment (number of people in a room, sound pressure level), and demographic factors (age, sex, and occupation type). In addition, we sought to identify relationships between sound preference and acoustic demands. The study was based on a semi-structured interview survey and objective measurements recorded in six facilities for the elderly in China. The results suggested that almost half of the interviewees chose not to add or abate any sound. For the remaining participants, the addition of mainly soothing music to the environment was required, indicating a considerable preference for it over natural sounds, stimulating music, and other sounds. Activity type was an important factor influencing acoustic demands, in that playing ball games and sitting still tended to engender demands for the addition of sounds, while people who were playing or watching Chinese chess did not wish to hear any sounds including soothing music. An analysis of the number of people in a room showed that if that number reached 12, demands for the abatement of sounds increased sharply, particularly for the sound of people talking. In addition, sound pressure level, age, sex, and occupation type (mental or physical work) influenced the demand for acoustic abatement, which involved the abatement of the sound of people talking or other noises and ‘no need to abate’. Natural sounds were seldom required during most activities, with the exception of chatting and sitting still, which is inconsistent with the extent to which people enjoy such sounds. However, there was a significant positive correlation between the elderly individuals’ preference for the overall acoustic environment and their demands for the addition of natural sounds. Furthermore, women were more likely to demand the addition of natural sounds, relative to men
