In this paper we present the utilization bound for Earliest Deadline First (EDF) scheduling on homogeneous mul-tiprocessor systems with partitioning strategies. Assuming that tasks are pre-emptively scheduled on each processor according to the EDF algorithm, and allocated according to the First Fit (FF) heuristic, we prove that the worst-case achievable(More)
Sixty-one children with insulin-dependent diabetes mellitus and twenty-three healthy subjects were investigated. The patients with diabetes mellitus aged 4 to 20 years (13.4 +/- 4.0) had had diabetes for 1 to 16 years (6.4 +/- 3.5). There were no cardiovascular risk factor other than diabetes. Patients received no medication other than insulin. The(More)
OBJECTIVE To ascertain the factors affecting the time between the initiation of treatment and obtaining three negative sputum smears. DESIGN In a study of 109 patients with pulmonary tuberculosis, the main variable was the period during which the patients had sputum smears once treatment was initiated. Multivariate analysis (multiple linear regression)(More)
In this paper we extend Liu & Layland's utilization bound for fixed priority scheduling on uniprocessors to homogeneous multiprocessor systems under a partitioning strategy. Assuming that tasks are pre-emptively scheduled on each processor according to fixed priorities assigned by the Rate-Monotonic policy, and allocated to processors by the First Fit(More)
Nowadays, enterprises providing services through Internet often require online services supplied by other enterprises. This entails the cooperation of enterprise servers using Web services technology. The service exchange between enterprises must be carried out with a determined level of quality, which is usually established in a service level agreement(More)
Web services are becoming an essential technology for the development of current distributed applications. Therefore, the organizations must be aware of the possibilities and limitations of the web services and their enabling technologies related to interoperability, performance, security, etc. Benchmarking techniques can provide very useful insights about(More)
