Assuming that the "platform": (processors, networks, and operating systems) are specified by the designer, a good "configuration" (the allocation of tasks to processors, priorities, and other aspects of the(More)
The time it takes to develop telecommunication standards must be reduced to allow companies to get features to the market faster. In order to achieve this objective, a process based on the combination of a set of modeling techniques has been proposed by Nortel Networks in the context of the Wireless Intelligent Network (WIN) standard development.

UNLABELLED Our patient had drainage of a large amoebic liver abscess. This got complicated by a severe degree of hypotension, which required aggressive fluid resuscitation and hydrocortisone support. Computerised tomography (CT) of the abdomen revealed bilateral adrenal gland haemorrhage (BAH) resulting in primary adrenal gland failure, which was the cause(More)
Synovial sarcoma accounts for about 10% of adult soft tissue sarcomas, with 80–90% located in the limbs. Gastrointestinal tract involvement is rare. Synovial sarcoma has a propensity for local recurrence and lung metastases, which can be delayed beyond 5 years. The t(X;18) translocation resulting in the expression of a SYT–SSX fusion protein is commonly(More)
