The present study aims to investigate the association between political connections and related-party transactions for the firms listed on the Tehran Stock Exchange (TSE). Sample includes the 485 firm-year observations from companies listed on the Tehran Stock Exchange during the years 2013 to 2017 and research hypothesis was tested using multivariate regression model based on panel data.We fin...

W the fi rst issue of volume number C57, the IEEE Transactions on Computers (TC) will enter a new year of publication, a long journey started more than 50 years ago. If you are an old timer like me who enjoys navigating through dusty paper copies of TC in your institutional library, you will be surprised to fi nd that, initially, volumes were numbered EC1 through EC16. This refl ects the origin...

as the e-commerce sites are being more secure and reliable in recent years and the number of transactions is rising rapidly, parallelism can help us to reduce response time and increase throughput for e-commerce transactions. this paper will investigate parallelism in on-line transaction processing. it aims to specify those aspects of e-commerce transactions that would profit from parallel proc...

The value of using a higher radix for modular multiplication in the context of RSA is investigated. The main conclusion is that for algorithms which perform the multiplication via repeated addition, there is, broadly speaking, a direct trade-off between space and time provided by change of radix. Thus chip area utilised is roughly proportional to speed. However, initially as the radix is increa...

In this paper, we propose a new concurrency control algorithm based on multi-agent systems which is an extension of majority protocol. Then, we suggest a clustering approach to get better results in reliability, decreasing message passing and algorithm’s runtime. Here, we consider n different transactions working on non-conflict data items. Considering execution efficiency of some different...

transaction per second. contrasts the Several companies intend to provide general-purpose processing systems capable of one thousand transactions This paper surveys the need for such systems and approaches being taken by three different groups. This paper appears in the proceedings of IEEE COMPCON-85, held in San Francisco in February 1985.
