    A Colour Design Tool Based on Empirical Studies

    A colour design tool targeted at both unskilled consumers and professional designers is currently under development, on the basis of psychophysical studies into semantic associations of colour, the cultural influences and colour harmony. From experimental results for single-colour associations, 3 underlying factors were identified: “warm-cool”, “heavy-light” and “active-passive”, which were found to agree well with those identified by earlier research. For colour-combination associations, an “additive property” of colour association was discovered: the semantic score of a colour combination can be determined by averaging semantic scores of each constituent colour in that combination. According to the experimental results, there were 4 general patterns of colour harmony: similarity in hue and chroma, difference in lightness, high lightness and the hue effects. While the proposed colour design tool is still in its development stage and has a number of shortcomings, the system is believed to provide practical assistance and support not only for unskilled users but also for designers.

    Colour Design for Carton-Packed Fruit Juice Packages

    The present research studies the relationships between observers’ expectations for 7 fruit juice packages and the colour design of the package. To do this, a two-stage experiment was conducted. At the first stage, we studied perceived colours for the fruit images shown on each package. At the second stage, fruit juice packages with 20 package colours were rated using 5 bipolar scales: colour harmony, preference, freshness, naturalness and product quality. The experimental results show that the observers tended to perceive fruit image colours lighter and more saturated than those measured using colour measuring instruments. Using factor analyses, we classified the 5 bipolar scales into 2 factors: Product Preference and Freshness. Package colour design was found to have significant impacts on both factors: similarity in chroma and hue between package colour and perceived fruit colour would lead to high product expectations. Keywords: colour design; colour harmony; product expectation; perceived image colour</p

    Influencing factors and stage characteristics of intelligent construction of rural tourism in Fujian

    With the help of qualitative analysis software Nvivo11, this paper makes a rooted analysis on the field text data of six rural tourism spots in Fujian Province. It shows that the influencing factors of the intelligent construction of rural tourism mainly including human capital, performance expectation, effort expectation, social impact, market demand and capital conditions. In the initial construction stage of rural tourism, the influence of capital conditions and human capital is stronger; in its development and construction stage, the impact of performance expectation is the most critical, followed by effort expectation and capital conditions; In its relatively mature stage, performance expectation and effort expectation are the dominant factors, followed by social influence. To promote the intelligent construction of rural tourism, effective measures should be taken according to the key factors in different development stages. It should be guided by the actual needs of tourists, pay attention to the fit with the positioning of rural tourism destination and target market, and avoid being intelligent for the sake of intelligence

    Effects of losses in the hybrid atom-light interferometer

    Get PDF
    Enhanced Raman scattering can be obtained by injecting a seeded light field which is correlated with the initially prepared collective atomic excitation. This Raman amplification process can be used to realize atom-light hybrid interferometer. We numerically calculate the phase sensitivities and the signal-to-noise ratios of this interferometer with the method of homodyne detection and intensity detection, and give their differences between this two methods. In the presence of loss of light field and atomic decoherence the measure precision will be reduced which can be explained by the break of the intermode decorrelation conditions of output modesComment: 9 pages, 7 figure

    Alimentary canal of fifth instar larvae of Lymantria dispar (Lepidoptera: Erebidae, Lymatriinae)

    Here, the alimentary canal of fifth instar larvae of the gypsy moth (Lymantria dispar) was re-investigated with light microscopy (LM), and for the first time with laser scanning confocalmicroscopy (LSCM) and scanning electronmicroscopy (SEM). We describe morphological characteristics and provide morphometric data. Well-developed dilator muscles and Malpighian bladders suggest a high capacity for food propulsion, excretion, absorption, and detoxification. The epithelium of the alimentary canal of L. dispar is histologically simple and that of the midgut is composed of columnar, goblet, and regenerative cells. Particular arrangement of the intima of crop with a central ventral region recalling a ladder and numerous folds was detected, indicating the capability for a large increase in volume to store food. Numerous spinules were observed on the cuticular intima of pylorus and spinules of a different type were observed on the pyloric valve, and these might assist in propelling the feces
