This paper proposes a technique, GALAXY, to speed up multicircuit simulation, where each circuit under simulation is identical in schematic but different in some parameters. GALAXY is based on the successive chord method, where the inverse Jacobian matrix (${J} ^{{-1}}$ ) is reused to simulate many circuits whose solutions are similar. GALAXY also speeds up single-circuit simulation by reusing ${J} ^{{-1}}$ ...
ARINC specification 653-2 describes the interface between application software and underlying middleware in a distributed real-time avionics system. The real-time workload in this system comprises of partitions, where each partition consists of one or more processes. Processes incur blocking and preemption overheads and can communicate with other processes in the system. In this work we develop compositional...
Wireless visual sensor networks have been implemented in several different fields such as environment monitoring, military applications, and robotic applications. Limiting by node's specification, the bandwidth and energy become critical issues for sensor nodes. For target tracking applications, robot can be used as a mobile sink. In this paper, we propose a mode scheduling mechanism, mobile sink,...
In this paper, we propose a novel state space model for the drum boilers with natural recirculation. The states of this model are the total mass and energy inventories. The main advantage of the model is that it has an affine structure in control variables. A passivity based inventory controller is developed, which ensures the asymptotic stability of the closed- loop boiler system. Numerical simulations...
