The magnitude of provider uncompensated care has become an important public policy issue. Yet existing measures of uncompensated care are flawed because they compare uninsured payments to list prices, not to the prices actually paid by the insured. We address this issue using a novel source of data from a vendor that processes financial data for almost 4000 physicians. We measure uncompensated ...

The security of the Bitcoin system is based on having a large amount of computational power in the hands of honest miners. Such miners are incentivized to join the system and validate transactions by the payments issued by the protocol to anyone who creates blocks. As new bitcoins creation rate decreases (halving approximately every 4 years), the revenue derived from transaction fees start to h...

The need for secure data transactions has become a necessity of our time. Medical records, financial records, legal information and payment gateway are all in need of secure data transaction process. There have been several methods proposed to perform secure, fast and scalable data transactions in web services. As the web servers deals with the huge amount of query it becomes really difficult t...

Financial transactions increase according to the economic growth of the nation. As India’s economy is growing rapidly large amount of money transactions are increasing rapidly. Apart from currency notes and credit/debit cards cheques plays very vital role in transaction of large amount of money for their ease and convenience. Due to this cheques are vulnerable to forgeries by anti-social elemen...

As in other application areas, there is an increasing need for managing a large amount of data in the real-time area. This need gave birth to a system called a real-time database system (RTDBS) that provides database operations with timing constraints. One typical timing constraint in an RTDBS is temporal consistency that states that a transaction must read temporally valid data objects. This r...

National Economic Input-Output (EIO) data describes the monetary transactions among economic sectors. The monetary transactions among these sectors form a weighted bi-directional network from a supply sector to a demand sector and the weight is equivalent to the transaction value between them. In this research, we study the properties of this network and identify patterns of inter-sector depend...

Supporting transactions processing over wireless broadcasting environment has attracted a considerable amount of research in a mobile computing system. To allow more than one conflicting transactions to be committed within the same broadcast cycle, the main broadcast cycle need to be decompose into a sub cycles. This decomposition contains both the original data to be broadcast in Rcast cycle a...
