conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. in the recovery system, super-critical an co2 is employed as the working fluid operating in a brayton cycle. low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes the hot gases lea...

This paper presents a composition method for stack-attributed tree transducers. Stackattributed tree transducers extend attributed tree transducers with a pushdown stack device for attribute values. Stack-attributed tree transducers are more powerful than attributed tree transducers due to the stack mechanism. We extend the existing composition method for attributed tree transducers to the comp...

Software testing is an integral part of modern software engineering practice. Past research has not only underlined its significance, but also revealed multi-faceted nature. The practice and adoption influenced by many factors that go beyond tools or technology. This paper sets out to investigate the context from practitioners’ point view mining analyzing sentimental posts on widely used questi...

We show the compactly supported motive of moduli stack degree n rational curves on weighted projective $${\mathcal {P}}(a,b)$$ is mixed Tate type over any base field K with $$\hbox {char}(K) \not \mid a,b$$ and has class $${\mathbb {L}}^{(a+b)n+1}-{\mathbb {L}}^{(a+b)n-1}$$ in Grothendieck ring stacks. In particular, this improves upon results (Han Park Math Ann 375(3–4), 1745–1760, 2019) regar...

Stack layouts and queue layouts of undirected graphs have been used to model problems in fault tolerant computing and in parallel process scheduling. However, problems in parallel process scheduling are more accurately modeled by stack and queue layouts of directed acyclic graphs (dags). A stack layout of a dag is similar to a stack layout of an undirected graph, with the additional requirement...

Programmable Thermal Dissociation (PTD) has been used to investigate the chemical speciation of Reactive Gaseous Mercury (RGM, Hg). RGM was collected on denuders and analyzed using PTD. The technique was tested in a field campaign at a coal-fired power plant in Pensacola, Florida. Stack gas samples were collected from ducts located after the electrostatic precipitator and prior to entering the ...

Any gray-scale image can be represented as a \stack" of a decreasing sequence of binary images, obtained by thresholding the gray-scale image at each level. Stack lters are a special class of gray-scale image operators whose ltered images can be represented as the stack of binary images resulting of applying an increasing binary operator for each image of the stack. A classical example of stack...

Background A previous study has demonstrated the feasibility of 3D phase-resolved functional lung (PREFUL) MRI in healthy volunteers and patients with chronic pulmonary disease. Before clinical use, repeatability ventilation parameters derived from PREFUL must be determined. Purpose To evaluate to compare testing (PFT). Study Type Prospective. Population Fifty-three subjects 13 obstructive dise...

conclusions treatment of neonatal respiratory failure with high rate mechanical ventilation may reduce some complications. results intraventricular hemorrhage (ivh) and air leak (e.g. pneumothorax) were less in hfppv group than conventional group (p = 0.012 and p = 0.038). the mean time needed for mechanical ventilation was lower in hfppv group, but this difference was not statistically signifi...
