Objective: Market anomalieschange with economic conditions, stock markets, selected samples, time periods and differences between industries. Revision of past forecasts leads to forecast error. The revisions result from new information. On the other hand, some managers slowly revise their forecasts in responding to new information. Therefore, the purpose of this research is to investigate the r...

Stock price synchronization is an important index to measure the content of idiosyncratic information in a company's stock price. Taking increasingly fierce market competition as background, this paper discusses relationship between strategic difference and China's with more noise trading, considers influence property right nature ownership concentration on relationship. The results show that: ...

Accurate and reliable time is necessary for financial and legal transactions, transportation, distribution systems, and many other applications. Time synchronization protocols such as NTP (the Network Time Protocol) have kept clocks of such applications synchronized to each other for many years. Nowadays there are many commercial GPS based NTP time server products at the market but they almost ...

This paper provides evidence on price rigidity at the product- and firm-level in Norway. A strong within-firm synchronization is found supporting theory of economies scope menu costs. The industry effects are to be small suggesting that firms either have some monopoly power, or a firm’s costs changing their own prices may larger than benefit responding competitors’ changes. These findings poten...

Two topics are presented: synchronization games and synchronization costs. In a synchronization game on a deterministic finite automaton, there are two players, Alice and Bob, whose moves alternate. Alice wants to synchronize the given automaton, while Bob aims to make her task as hard as possible. We answer a few natural questions related to such games. Speaking about synchronization costs, we...

The initial cell search procedure of a terminal in an asynchronous wideband CDMA (WCDMA) system is discussed. The procedure consists of the following steps (not necessarily in this order): chip and frame synchronization; identification and synchronization of the long scrambling code; and determination of the target base station identity. Higuchi et al. [1] proposed a cell search method for such...

The audio and video Synchronization is extremely necessary. The synchronization loss between image and sound continues to disturb observers and irritate telecasters. The demand is to assure synchronization without adjusting content at the same time as still retaining price low. The objective of the synchronization is to line up both the audio and video signals that are processed individually. T...
