Instruction Level Parallelism (ILP) of applications is typically limited and variant in time, thus during application execution some processor Function Units (FUs) may not be used all the time. Therefore, these idle FUs can to execute replicated instructions, improving reliability. However, existing approaches either schedule instructions based on compiler or consider processors with identical ...

Network Function Virtualization (NFV) can support customized on- demand network services with flexibility and cost-efficiency. Virtual (VNF) instances need to be scaled out, in, reallocated across the NFV infrastructure (NFVI) avoid a violation of service agreements when traffic changes. However, selecting new placement VNFs for migrating function chain (SFC) is an issue efficient control. We p...

This article refers to ‘The significance of left ventricular ejection time in heart failure with reduced fraction’ by A.S. Alhakak et al., published this issue on pages 541–551. ‘Time present and past are both perhaps future contained past’—Thomas S. Eliot Cardiac function is continuous without a beginning or end, thus one phase the cardiac cycle, certain degree, dependent from previous phase. ...
