New Internet applications integrates data, voice and video forwarding. These applications need Quality of Service (QoS) to control their traffic. Additional services in the TCP/IP (Transfer Control Protocol / Intemetworking Protocol) architecture were proposed to assure this requirement. Additionally, ATM is an important transmission technology in high speed networks due to its capability to send integrated data, voice, and video with QoS. This paper reports the use of ATM technology to support new IP services. This work proposes to study an IP/ATM switching model and simulates the basic characteristics of this architecture.
The Coronary Cardiac Disease (CCD) is considered as the primary cause of death in many countries, including Brazil. Considering the steadily increase of cases and the high cost of coronariopathy treatment, early diagnosis and investments in preventive measures have become a priority.For the reasons exposed above, a virtual environment called Virtual Medical Office (VMO) is being developed, which simulates the process of decision making in a clinical surgical judgment for the definition of a therapeutic conduct for patients with coronariopathy.The VMO is being supported to the definition of a therapeutic conduct in patients: clinical conduct, myocardial revascularization or coronary angioplasty. For this project, several modules are being developed in the construction of the VMO, including an Educational Module that supports learning interactions on the Cardiology area.The Educational Module is being developed on the bases of MATHEMA architecture. This architecture and its knowledge modelling framework are being used in the development of a multi-agent tutoring system that integrates to other VMO modules. For this tutoring system, a domain ontology covering the coronary cardiac disease related to cardiology knowledge is being developed using the Protégé knowledge editor.Buscar na Web
