Data warehouses (DW) are built by gathering information from distributed information sources (ISs) and integrating it into one customized repository. In recent years, work has begun to address the problem of view maintenance of DWs under concurrent data updates of diierent ISs. Popular solutions such as ECA and Strobe achieve such concurrent maintenance however with the requirement of quiescenc...

In many industrial environments, systems are required to perform a sequence of operations (or missions) with finite breaks between each operation. During these breaks, it may be advantageous to perform repair and replace on some of the system’s components. However, it may not be possible to perform all desirable maintenance activities prior to the beginning of the next mission due to limitation...

This paper describes the development of a computerized line maintenance simulation model for strategic manpower planning at Continental Airlines for one of their major maintenance stations at Newark airport. The simulation model provides guidelines to the development of enhanced staffing models and a better understanding of resource requirements on a daily basis. The proposed simulation model c...

Postoperative analgesia, once established initially by the titration method, is sustained with a flexible regime of papaveretum, infused continuously with a portable syringe pump. The initial analgesic requirement (TAR) for titrating the pain threshold level, was between 4 and 10 mg of papaveretum and the maintenance dose between 1 and 1-66 mg/hr for the first 24 hr and between 083 and 1 mg/hr ...

Acceptance testing is a kind of testing performed prior to software delivery. In the agile approach, acceptance test suites are specified by analysts and customers during the requirement elicitation phase and used to support the development/maintenance activities. This paper reports an experiment with master students that investigates on the usefulness of executable acceptance test cases, devel...

A comparative slaughter trial was conducted to estimate the phosphorus (P) requirement for maintenance and growth of crossbred lambs of Dorper with a Chinese indigenous sheep breed, thin-tailed Han sheep. Thirty-five Dorper×thin-tailed Han crossbred, noncastrated ram lambs (20.3±0.22 kg of shrunk body weight (SBW)) were used. Seven lambs were randomly chosen and slaughtered at 20 kg SBW as the ...
