The measurement of natural airflows is challenging, because low pressures involved in ventilation, and their variability. tracer gas decay method the most used to assess airflows. It is, however, not adapted multi-zone dwellings. A protocol based on tested here involving Kalman filter, a correction procedure concentrations. Both intend allow global airflow-rate passive-stack ventilated dwelling...

Stack processing, and in particular stack processing for the least recently used replacement algorithms, may present computational problems when it is applied to a sequence of page references with many different pages. This paper describes a new technique for LRU stack processing that permits efficient processing of these sequences. An analysis of the algorithm and a comparison of its running t...

The stack model of execution uses a stack to hold temporary results during evaluation of a program. Systems such as Java virtual machines that use this model can be implemented so that they have more efficient access to the stack than to local variables. Thus, converting local variable accesses into stack accesses can improve the performance of stack-based programs, as suggested by the experime...

Power optimization is the major problem in digital circuit design. In this paper using MTCMOS and stack techniques are proposed. Multi threshold CMOS sleep stack and logic stack, super cutoff sleep stack and logic stack are proposed. Stacking is introduced in MTCMOS concept which decreases leakage power based on the power dissipation of pMOS and nMO Stransistor. MTCMOS technique uses multiple v...

We study the combinatorial FIFO stack-up problem. In delivery industry, bins have to be stacked-up from conveyor belts onto pallets with respect to customer orders. Given k sequences q1, . . . , qk of labeled bins and a positive integer p, the aim is to stack-up the bins by iteratively removing the first bin of one of the k sequences and put it onto an initially empty pallet of unbounded capaci...

in this research the simulation of an air independent proton exchange membrane fuel cell (pemfc) propulsion system was taken into consideration. the system consists of several parts including pem fuel cell stack, metal hydride and liquid oxygen (lox) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. the heat recovery...

"Multi-Protocol Label Switching (MPLS)" [1] requires a set of procedures for augmenting network layer packets with "label stacks", thereby turning them into "labeled packets". Routers which support MPLS are known as "Label Switching Routers", or "LSRs". In order to transmit a labeled packet on a particular data link, an LSR must support an encoding technique which, given a label stack and a net...

A unidirectional heap is a heap where all pointers go in one direction, e.g. from newer to older objects. For a strict functional language , such as Erlang, the heap may be arranged so that it is unidirec-tional. We here present a compacting garbage collection algorithm which utilizes the fact that a heap is unidirectional. Only one memory space is used in our algorithm. In fact, no extra memor...

There are infinite sequences of graphs {Gn} where |Gn| = n such that the minimal dominating sets for H × Gi fall into predictable patterns, in light of which γ(Gn × H) may be nearly linear in n; the coefficient of linearity may be regarded as the average density of the dominating set in the H-fibers of the product. The specific cases where the sequence {Gn} consists of cycles or path is explore...
