The Intel® ItaniumTM architecture provides a virtual register stack of unlimited size for use by software. New virtual registers are allocated on a procedure call and deallocated on return. Itanium processors implement the register stack by means of a large physical register file, a mapping from virtual to physical registers, and a Register Stack Engine (RSE) that saves and restores the content...

Leakage power consumption of current CMOS technology is already a great challenge. ITRS projects that leakage power consumption may come to dominate total chip power consumption as the technology feature size shrinks. We propose a novel leakage reduction technique, named “sleepy stack,” which can be applied to general logic design. Our sleepy stack approach retains exact logic state – making it...

variability of tidal volume and respiratory rate in normally breathing man has long been demonstrated [1]. however because of lack of knowledge and technology primary ventilators could only deliver a fixed tidal volume in a fixed rate the so called volume controlled ventilation (vcv). vcv was volume preset time triggered and cycled and there was no synchronization with patient’s breaths. at tha...

abstract background: different modes of mechanical ventilation are used for respiratory support after coronary artery bypass graft (cabg). this study aimed to compare the effect(s) of using adaptive support ventilation (asv) and synchronized intermittent mandatory ventilation (simv) on the length of mechanical ventilation (intubation duration) and hospital stay after coronary artery bypass graf...

More than a few failures of Transportation System Networks are caused by kernel stack overflow. Transportation System Networks use operating systems like Android that employs the Linux kernel which has a fixed size kernel stack. Unfortunately, nowadays there is no mechanism to avert the kernel from overflowing the stack. With the purpose of putting a stop to this fault, we present a dynamically...

We consider the stack of coherent algebras with proper support, a moduli problem generalizing Alexeev and Knutson's stack of branchvarieties to the case of an Artin stack. The main results are proofs of the existence of Quot and Hom spaces in greater generality than is currently known and several applications to Alexeev and Knutson's original construction: a proof that the stack of branchvariet...

The four different types of stack filters, type-0 through type-3, are determined by four different shapes of the on-set of the positive Boolean function from which the stack filter is constructed. Under all three appending strategies commonly considered in the literature---first and last value carry-on strategy, constant value carry-on strategy, and the circular approach--stack filters of type-...
