关键词： 交易行情   花卉拍卖   价格上涨   节日市场   供货量   圣诞节  

摘要： 2015年12月至2016年1月总体交易概况。2015年12中旬．日供货量在160-220万枝．受到“圣诞节”影响．节前交易价格上涨。12月17日起交易均价大幅上涨．到19日时交易均价达到了163元／枝，创下了月度均价最高值。到12月下旬供货量大幅增加，这主要是因为受到“元旦”节日市场的影响。

摘要： Spectral analysis using Fourier techniques is popular with gene prediction because of its simplicity. Model-based autoregressive (AR) spectral estimation gives better resolution even for small DNA segments but selection of appropriate model order is a critical issue. In this article a technique has been proposed where Yule-Walker autoregressive (YW-AR) process is combined with principal component analysis (PCA) for reduction in dimensionality. The spectral peaks of DNA signal are used to detect protein-coding regions based on the 1/3 frequency component. Here optimal model order selection is no more critical as noise is removed by PCA prior to power spectral density (PSD) estimation. Eigenvalue-ratio is used to find the threshold between signal and noise subspaces for data reduction. Superiority of proposed method over fast Fourier Transform (FFT) method and autoregressive method combined with wavelet packet transform (WPT) is established with the help of receiver operating characteristics (ROC) and discrimination measure (DM) respectively.
