Mapping of software onto hardware elements under platform resource constraints is a crucial step in the design of embedded systems. As embedded systems are increasingly integrating both safety-critical and non-safety critical software functionalities onto a shared hardware platform, a dependability driven integration is desirable. Such an integration(More)
CONTEXT Foot infection is the most common complication of diabetes mellitus in the Caribbean. Diabetic foot infections place a heavy burden on health care resources in the Caribbean. OBJECTIVE To evaluate the treatment-related costs for diabetic foot infections in a Caribbean nation. METHODS We identified all patients with diabetic foot infections in a(More)
Embedded systems increasingly encompass both dependability and responsiveness requirements. While sophisticated techniques exist, on a discrete basis, for both dependability/fault-tolerance (FT) and real-time (RT), the composite considerations for FT+RT are still evolving. Obviously the different objectives needed for FT and RT make composite optimization(More)
Moving from the traditional federated design paradigm, integration of mixedcriticality software components onto common computing platforms is increasingly being adopted by automotive, avionics and the control industry. This method faces new challenges such as the integration of varied functionalities (dependability, responsiveness, power consumption, etc.)(More)
Automotive software systems are becoming increasingly complex, driven both by advances in technology and by demands for more powerful applications. The design of such complex systems calls for advanced techniques in requirements engineering. This paper is concerned with developing and validating a new concept in order to elicit and specify user requirements(More)
Embedded systems increasingly entail complex issues of hardware–software (HW–SW) co-design. As the number and range of SW functional components typically exceed the finite HW resources, a common approach is that of resource sharing (i.e., the deployment of diverse SW functionalities onto the same HW resources). Consequently, to result in ameaningful(More)
Active Queue Management (AQM) is receiving wide attention as a promising technique to prevent and avoid congestion collapse in packet-switched networks. By providing advanced warning of incipient congestion, end nodes can respond to congestion before router buffer overflows and hence ensure improved performance. Random Early Discard (RED) is an IETF(More)
AIMS To examine the microbiologic profile of diabetic foot infections in order to guide empiric antibiotic choices. METHODS All patients with moderate-severe diabetic foot infections at a tertiary care facility were identified from July 2011 to June 2012. Culture samples were routinely collected before empiric antibiotics were commenced. Retrospective(More)
The integrated EU-project DECOS aims at the provision of enabling technologies to move from federated to integrated distributed architectures in order to reduce development, validation and maintenance costs, and to increase the dependability of embedded applications in various application domains. A major concern is the development of an integrated(More)
INTRODUCTION This study evaluates the epidemiology of diabetic foot infections in an Eastern Caribbean nation in order to direct public health preventive measures. METHODS We prospectively identified all patients with diabetic foot infections who were admitted to tertiary care hospitals across Trinidad and Tobago from July 2011 to June 2012. A(More)
