SUMMARY Mutual exclusion and general synchronization of concurrent processes ('tasks') are well-known principles for constructing reliable real-time systems. This pap'er shows how to implement these principles under a typical commercial operating system which provides incomplete synchronization operations. The problem of synchronizing erroneous tasks is(More)
Knee joint-related symptoms are frequent and the use of MRI as a diagnostic tool is common. About 25% of MRIs show meniscal degeneration (MD). As the natural history of MD has not been well described, we studied the long-term outcome of 50 MDs. 45 patients were initially evaluated by a MRI, and clinical examination and later by another MRI. After 5 years,(More)
