To achieve an efficient utilization of cluster systems, a proper programming and operating environment is required. In this context, mobile agents are of growing interest as base for distributed and parallel applications. As mobile and autonomous software units, mobile agents can execute tasks given to the system and allocate independently all the needed(More)
The UML Testing Profile provides support for UML based model-driven testing. This paper introduces a methodology of how to use the testing profile in order to modify and extend an existing UML design model for test issues. As a case study, a new roaming algorithm for bluetooth devices has been develped at the University of Lübeck, is modelled using UML. The(More)
The diuretic effect of the supine position was evaluated in six patients with cirrhosis and ascites and six with congestive cardiac failure. After fasting overnight in bed the patients received bumetanide 1 mg intravenously and were then immediately randomly assigned to either bed rest in the supine position or normal daily activity in the upright position(More)
In a double-blind group comparative study, 36 adult, birch pollen-allergic outpatients with seasonal rhinoconjunctivitis, were treated with either oral prednisolone 7.5 mg daily for 3 weeks or an injection with 2 ml suspension of betamethasone dipropionate and betamethasone disodium phosphate (Diprospan) immediately prior to the birch pollen season. Both(More)
The possibility that verapamil might increase the sensibility of colorectal carcinomas to doxorubicin was studied in 24 patients without previous cytotoxic chemotherapy. The treatment started with oral verapamil, which was escalated up to the individual maximum tolerable dose (defined by prolongation of P-Q in ECG, fall in blood pressure, or dizziness). The(More)
In late 2001, the Object Management Group issued a Request for Proposal to develop a testing profile for UML 2.0. In June 2003, the work of UML Testing Profile has finally been adopted by the OMG. The Testing Profile provides support for UML based model-driven testing. This paper introduces a methodology of how to use the testing profile in order to modify(More)
An attempt was made to study the efficacy in and one of the errors of randomized multicenter clinical trials. Efficacy was defined for the present purpose as a statistically significant clinical difference between at least 2 of the treatment arms studied. The error studied was defined here as non-excluded protocol deviations found during a systematic record(More)
