A new model of wall pressure fluctuations

Turbulent Wall-Pressure Fluctuations: New Model for Off-Axis Cross-Spectral Density

Models for the distribution of the wall-pressure under a turbulent boundary layer often estimate the coherence of the cross-spectral density in terms of a product of two coherence functions. One such function describes the coherence as a function of separation distance in the meanow direction, the other function describes the coherence in the cross-stream direction. Analysis of data from a larg...

Providing a model for predicting blood pressure fluctuations after induction of general anesthesia with data mining: a brief report

Background: Fluctuations in blood pressure after induction of general anesthesia have played a significant role in complications of surgery. Therefore, the present study was performed by identifying the causes of blood pressure fluctuations after induction of anesthesia, predicting and preventing them. Methods: For this study which is a retrospective cohort, data mining methods in the data set...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Investigation of vessels pressure effect on PEM electrolyzer performance by using a new OneDimensional Dynamic Model

In recent years energy shortage and environmental impacts due to consuming fossil fuels have led to developing renewable energy sources systems. Since these sources are not reliable and are usually time dependent, an energy storing system like hydrogen production is required. In this regard, PEM electrolyzer can be efficiently used to decompose liquid water into hydrogen and oxygen. Because of ...
