Flexible Framework for Real-Time Embedded Systems Based on Mobile Cloud Computing Paradigm

The development of applications as well as the services for mobile systems faces a varied range of devices with very heterogeneous capabilities whose response times are difficult to predict. The research described in this work aims to respond to this issue by developing a computational model that formalizes the problem and that defines adjusting computing methods. The described proposal combines imprecise computing strategies with cloud computing paradigms in order to provide flexible implementation frameworks for embedded or mobile devices. As a result, the imprecise computation scheduling method on the workload of the embedded system is the solution to move computing to the cloud according to the priority and response time of the tasks to be executed and hereby be able to meet productivity and quality of desired services. A technique to estimate network delays and to schedule more accurately tasks is illustrated in this paper. An application example in which this technique is experimented in running contexts with heterogeneous work loading for checking the validity of the proposed model is described.

Improving the mortality information system in Portugal

The inability to invest in and develop mortality information systems has been considered the single most critical failure in health information systems. Health information systems are an integral part of health systems. This includes strengthening not only the information content but also the information systems themselves, health information platforms and infrastructure. In this article, particular focus has been placed on the regional and inter-sectoral approach to implementation adopted in Portugal. The article shows how legal and operational barriers have been overcome and focuses on the potential of the new system to improve the quality and timeliness of mortality statistics.
