Statistical and Fourier analysis methods of time series representing fluctuations of stock market in general and Indian stock markets in particular are well known. This work is motivated by a recent paper by Guharay [Operations Research and Financial Engineering, Princeton University, Princeton, NJ, preprint, 2002] where he has studied trends in the S & P 500 for various time periods using wavelet tools. Our paper deals with a few Indian and Saudi stock prices and return fluctuation for a certain period of time. The main objective of the analysis is to understand the dynamics of the Indian and Saudi stock markets. We look for similarities, point of abrupt changes, normalized data, return, volatility, graph, pure and noise part, correlation lengths, and signal-to-noise ratio. 相似文献

Library consortia are under increasing scrutiny regarding their value to member libraries. Most consortia offer a suite of services which can be valued either quantitatively or qualitatively to determine a return on investment for money and time put into consortial activities. Various common consortial activities are discussed with thoughts regarding their value to local libraries. Recommendations and suggestions are provided on how to perform a Cost Benefit Analysis (CBA)/Return on Investment (ROI). 相似文献

财政部2018年7月颁发的《知识产权会计信息披露规定(征求意见稿)》将知识产权信息披露的规范化提上了日程。本文首先建立了知识产权信息披露指数来反映上市公司知识产权信息披露状况,并以信息技术业为例进行了实证分析。在此基础上,对知识产权信息披露指数的价值相关性进行了分析。实证研究表明：上市公司知识产权信息披露状况间存在较为明显的差异,信息披露状况对公司价值有显著性影响并呈现出正相关关系。 相似文献

在哈代的小说中，视象被巧妙地安排在小说的整体结构中，以喻指人物关系，暗示人物命运，构造出严密有效的隐喻体系。《还乡》中，哈代借助视点、位置、角度等要素，充分调动了视觉隐喻的功能，这对于塑造人物形象、烘托小说主题有重大意义。 相似文献
