Transactional memory systems trade ease of programming with runtime performance losses in handling transactions. This paper focuses on starvation effects that show up in systems where unordered transactions are committed on a demand-driven basis. Such simple commit arbitration policies are prone to starvation. The design issues for commit arbitration policies are analyzed and novel policies tha...

----------------------------------------------------------------------ABSTRACT----------------------------------------------------------The steady growth in electronic transactions has promoted the Automated Teller Machine (ATM) thereby making it the main transaction channel for carrying out financial transactions. However, this has also increased the amount of fraudulent activities carried out...

The amount of online transactions is growing these days to a large number. A big portion of these transactions contains credit card transactions. The growth of online fraud, on the other hand, is notable, which is generally a result of ease of access to edge technology for everyone. There has been research done on many models and methods for credit card fraud prevention and detection. Artificia...

In this paper, we present formalization and an implementation of a linear hashing algorithm in nested transaction environment to handle large amount of data with increased concurrency. Nested transactions allow parallel execution of transactions, and handle transaction aborts in our system. First, We formalize the nested transaction model in a linear has structure environment using wellknown I/...

In this paper we analyze the Ancona wholesale fish market (MERITAN) where transactions take place in three simultaneous Dutch auctions. Our objective is to characterize the behavior of market participants and, in particular, buyers in such a market structure. Our analysis of the data shows that buyer-seller relationships are less important than in a pairwise bargaining market such as the Marsei...

transaction cost economics (tce), as a subset of new institutional economics (nie), is the combination of economics, organization and law. noble prize in 2009 was dedicated to oliver williamson who was the most popular face in the economics as tce main contributor. in tce, the main issues on the one hand is how institutions follow characteristics of transactions, on the other hand, the making o...

Micropayments are electronic payments of small amount. Given their low value, the cost of the corresponding electronic transactions should also be kept low. Current micropayment schemes allow a regular amount of money withdrawn from a bank to be split into fixedvalue coupons, each of which is used for one micropayment. A more flexible mechanism is proposed in this paper, whereby coupons of vari...

Bitcoin is an online distributed ledger in which coins are distributed according to the unspent transaction output (UTXO) set, and transactions describe changes to this set. Every UTXO has associated to it an amount and signature verification key, representing the quantity that can be spent and the entity authorized to do so, respectively. Because the ledger is distributed and publicly verifiab...
