Memory-mapped transactions
Memory-mapped transactions combine the advantages of both memory mapping and transactions to provide a programming interface for concurrently accessing data on disk without explicit I/O or locking operations. This interface enables a programmer to design a complex serial program that accesses only …

An investigation into remote transactions
Remote transactions globally transfer trillions of dollars annually. Many of these information exchanges are mediated, implicitly or explicitly, by a complex web of agencies that add to costs and introduce additional opportunities for error or misconduct. Further, additional records are created as …

Coordinating Transactions For Data Services
… to handle. Traditional techniques to handle transactions in DDBS were not designed with Web services in mind and when applied to Web services need to establish coordination amongst them to process the transactions and maintain data consistency. This thesis presents the design and development …

Essays in Corporate Equity Transactions
… two essays dealing with corporate equity transactions. The first essay concerns an equity issuing transaction, the initial public offering (IPO), and specifically lockups, which restrict sales by pre-IPO shareholders. We improve upon the methodology for testing theory related to lockup …

Parallel execution for conflicting transactions
… databases only obtain parallel performance when transactions do not conflict. Conflicting transactions are executed one at a time in order to ensure that they have serializable effects. Sequential execution on contended data leaves cores idle and reduces throughput. In other parallel programming …

Optimal execution for portfolio transactions
In my thesis I explore the problem of optimizing trading strategies for complex portfolio transitions. Institutional investors run into this issue during periodic portfolio rebalancing or transition between asset managers. The costs of rebalancing can be broadly broken into trading costs (both the …

Three Essays On Odd-Lot Transactions
… dissertation consists of three essays on odd-lot transactions. The first essay investigates the role odd lot trades play in equity markets, as well as how this role has changed over three distinct time periods- 2010, 2007, and 2005. In each of these time periods, we document the determinants of …

Using ethereum transactions to deanonymize senders
… In this thesis, we perform timing analysis on transactions propagated through Ethereum networks to identify the origin nodes. We build a tool called TxSniper to verify our approach on Ethereum's main network. We find that we can identify the origin with a 70% probability; this method is not …

Scheduling Memory Transactions in Distributed Systems
… and Sun's dataflow execution model, where transactions are immobile and objects are migrated to invoking transactions, relying on directory-based cache-coherence protocols to locate and move objects. Within this execution model, the proposed schedulers target different DTM models. …

Managing malicious transactions in mobile database systems
… not fully protect occurrence of these malicious transactions. These requires human intervention in some form or other to detect malicious transactions. In a database, a transaction can affect the execution of the subsequesnt transactions thereby spreading the damage and hence making the attack …

Fast transactions for multicore in-memory databases
… the overhead of concurrency control for most transactions (at the cost of increasing it for cross-partition transactions)? Or should cores access a shared data structure instead? We investigate this question in the context of a fast in-memory database. We describe a new transactionally …

Long Running Transactions Within Enterprise Resource Planning Systems
… organiational process and ensure that completed transactions in a business process are not processed in any other process. Practically, LRTs models have various problems, such as the rollback and check-pointing activities. This led to the use of Communication Closed Layers (CCLs) for decomposing …

Hybrid STM/HTM for nested transactions in Java
… of hardware capacity issues (causing large transactions to fail), or compatibility restrictions on the processor instructions permitted within hardware transactions (causing transactions that execute those instructions to fail). In such cases, programs must include failure-handling code to …
