We present a systematic way of studying state machine based design spaces and apply it to the study of asynchronous pipelines. Starting with the specification of the most concurrent behaviour as a state machine, all possible valid smaller designs may be generated by systematically removing structured patterns of output states (L cuts) and input states (R cuts). Taking the cartesian product of c...

Buried pipeline systems are commonly used to transport water, sewage, oil, natural gas and other materials. In the conterminous United States, there are about 77,109 km (47,924 miles) of crude oil pipelines, 85,461 km (53,114 miles) of refined oil pipelines and 67,898 km (42,199 miles) of natural gas pipelines (FEMA, 1991). The total length of water and sewage pipelines is not readily available...

Scheduling product batches in pipelines is a very complex task with many constraints to be considered. Several papers have been published on the subject during the last decade. Most of them are based on large-size MILP discrete time scheduling models whose computational efficiency greatly diminishes for rather long time horizons. By introducing an MILP continuous representation in both time and...

Hartmann’s procedure, first described by the French surgeon Henri Albert Hartmann in 1921, is one of the most commonly performed operations. This paper examines the history behind this operation and assesses its significance in modern surgical practice.

We present opinion recommendation, a novel task of jointly generating a review with a rating score that a certain user would give to a certain product which is unreviewed by the user, given existing reviews to the product by other users, and the reviews that the user has given to other products. A characteristic of opinion recommendation is the reliance of multiple data sources for multi-task j...

We present opinion recommendation, a novel task of jointly predicting a custom review with a rating score that a certain user would give to a certain product or service, given existing reviews and rating scores to the product or service by other users, and the reviews that the user has given to other products and services. A characteristic of opinion recommendation is the reliance of multiple d...
