Many new kinds of protocols, e.g. for information sharing, security, etc., are being developed day-to-day which often leads to rapid, premature developments. Many protocols have not scaled to satisfy important properties like deadlock and livelock freedom, since MDA focuses on the rapid development rather than on the quality of the developed models. In order to fix the above, we introduce a 2-Phase strategy based on the UML state machine and sequence diagram. The state machine is converted into PROMELA code as a protocol model and its properties are derived from the sequence diagram as Linear Temporal Logic (LTL) through automation. The PROMELA code is interpreted through the SPIN model checker, which helps to simulate the behavior of protocol. Later the automated LTL properties are supplemented to the SPIN for the verification of protocol properties. The results are compared with the developed UML model and SPIN simulated model. Our test results impress the designer to verify the expected results with the system design and to identify the errors which are unnoticed during the design phase.展开更多

A total of 248 studies were read and nine included. The papers were analysed and data were extracted by categorizing the four components of rehabilitation: assessment, goal setting, intervention and reassessment. The results revealed that interdisciplinary teamwork was a prerequisite for rehabilitation and that nurses’ position in post-stroke care was unclear and limited. In addition, rehabilitation strategies, interdisciplinary cooperation, education and training are important aspects of the rehabilitation process. This study highlights the need for one valid and reliable assessment tool that incorporates communication problems. In conclusion, persons with aphasia should be more involved in their own rehabilitation, which means that the interdisciplinary team members must be educated to communicate appropriately with them.展开更多

In most of the distributed environments, the message is the way that they are communicated α with each other. But they can not be guaranteed to arrive at the right time. In this paper, we discuss the save functions in the Specification and Description Language (SDL) language. With these functions, a new way of transferring message can be realized reliably and efficiently. Finally, we give the simulation result according to the tools—? 玈DT .展开更多
