To achieve timeliness for transactions in a distributed real-time main memory database, we store each database replica at every node, allowing all transactions to be executed locally. With detached replication, updates are not replicated to other nodes within the execution of the transaction, but are logged and replicated at low priority when system resources allow that. In such a system concur...

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...

The effects of the Covid-19 pandemic process on sectoral distribution card payment transactions made over internet in country were analyzed with variance decomposition model, and differences between pre-Covid (June 2019 - March 2020) period post-Covid (April 2020 January 2022) revealed. sectors highest increase domestic use (transaction amount) cards (in terms their share total usage) electrica...

Mining frequent itemsets over high speed, continuous and infinite data streams is a challenging problem due to changing nature of data and limited memory and processing capacities of computing systems. Sliding window is an interesting model to solve this problem since it does not need the entire history of received transactions and can handle concept change by considering only a limited range o...

the concept of dhimma and ‘uhda (obligation and undertaking) comprises one of the very important subdivisions of commitments in shī‘a jurisprudence. the application of these two terms is very common in legal texts, both in discourses on devotional acts and the discourses concerning transactions (including transactions in specific sense and delictual liability - ḍimān). some contemporary jurispr...

the choice of which products to stock among numerous competing products and how much space to allocate to those products are central decisions for retailers. this study aimed to apply data mining approach so that, we got needed information from large datasets of sale transactions to find the relations between products and to make product assortments. thus, we represented a model for product ass...

trade relationships built through production chains appear to be lasting due to relation-specific nature of the transactions, compared with the usual transactions of goods sold on the open market. this paper aims to verify such stability of international production networks at the global level, with special emphasis on intra-east asian trade. a series of survival analyses provide an evidence su...

In a stylized continuous-time model of a small open economy with perfect capital mobility and a pegged exchange rate, I analyze an experiment in which domestic residents expect a future devaluation. Taking the public’s expectations as exogenous and allowing them to be divergent, I analyze in a short time period before the expected devaluation takes place how transactions of short-term collatera...
