چکیده
It is well-known that news is essential in financial markets. The amount of news releases is continually growing due to the expansion of communication media in today’s computerised world, and the ability to correctly and efficiently interpret financial information has become much more important in trading. Financial news analytics allow the trader to significantly reduce the latency time to react to all market or stock relevant events. The general idea is to automate human economic and financial reasoning when processing news streams at high speed, including collection, extraction, aggregation and categorization of data. Text analytical algorithms are then employed to transform the qualitative content of news feeds to quantitative investment relevant sentiment scores, allowing the trader to predict direction or volatility of price movements. News streams can also provide other financially relevant information to help investors to revise their strategy or rebalance their portfolio. 1 Version: 23 July 2012

متن کاملA Sub-threshold 9T SRAM Cell with High Write and Read ability with Bit Interleaving Capability
This paper proposes a new sub-threshold low power 9T static random-access memory (SRAM) cell compatible with bit interleaving structure in which the effective sizing adjustment of access transistors in write mode is provided by isolating writing and reading paths. In the proposed cell, we consider a weak inverter to make better write mode operation. Moreover applying boosted word line feature ...
