In this paper, we present an approach to easily define flexible and reliable services compositions. We introduce a new concept called transactional patterns to specify flexible and reliable composite Web services. A transactional pattern is a convergence concept between workflow patterns and advanced transactional models. It can be seen as a coordination pattern and as a structured transaction....

A major challenge of Transactional memory implementations is dealing with memory accesses that occur outside of transactions. In previous work we showed how to specify transactional memory in terms of admissible interchanges of transaction operations, and gave proof rules for showing that an implementation satisfies its specification. However, we did not capture non-transactional memory accesse...

Transactional data structures with the same performance of highly concurrent data structures enable performance-competitive transactional applications. Although Software Transactional Memory (STM) is a promising technology for designing and implementing transactional applications, STM-based transactional data structures still perform inferior to their optimized, concurrent (i.e. non-transaction...

In this paper we present CMTJava, a domain specific language for composable memory transactions [7] in Java. CMTJava provides the abstraction of transactional objects. Transactional objects have their fields accessed only by special get and set methods that are automatically generated by the compiler. These methods return transactional actions as a result. A transactional action is an action th...

the purpose of this quantitative correlation study was to determine the extent to which the role of leadership style preferences correlate with employee satisfaction with supervision among employees and leaders of an iranian oil company. this study measured preferences for each of five common leadership styles and examined correlations with measures of employee satisfaction. the styles studied ...

Transactional patterns are used to specify flexible and reliable composite Web services. A transactional pattern is a convergence concept between workflow patterns and advanced transactional models. These are of coordination patterns and as a structured transaction. This project proposes an event-driven approach to validate the transactional behavior of service compositions. The transactional b...

A transactional memory simplifies the concurrency management in multicore systems by permitting sets of load and store instructions to be executed in an atomic way. The correct results for concurrent transactions and the execution time strongly depend on the coherency potentials, rollback capabilities and strategies of the transactional memory. A transactional memory can be implemented as a Har...
