ANALYSIS OF AERODYNAMIC NOISE CHARACTERISTICS OF HIGH-SPEED TRAIN PANTOGRAPH WITH DIFFERENT INSTALLATION BASES

Analysis of Aerodynamic Noise Characteristics of High-Speed Train Pantograph with Different Installation Bases

The high-speed-train pantograph is a complex structure that consists of different rod-shaped simply southern cat shirt and rectangular surfaces.Flow phenomena around the pantograph are complicated and can cause a large proportion of aerodynamic noise, which is one of the main aerodynamic noise sources of a high-speed train.Therefore, better underst

Best PEEP trials are dependent on tidal volume

Abstract Determining the optimal positive end-expiratory pressure (PEEP) in patients with acute respiratory distress syndrome remains an area of active investigation.Most trials individualizing PEEP optimize one physiologic parameter (e.g., driving pressure) by titrating PEEP read more while holding other ventilator settings constant.Optimal PEEP,

Multivariate return periods in hydrology: a critical and practical review focusing on synthetic design hydrograph estimation

Most of the hydrological and hydraulic studies refer to the notion of a return period to quantify design variables.When dealing with multiple design variables, the well-known univariate statistical analysis is no longer color touch 7/97 satisfactory, and several issues challenge the practitioner.How should one incorporate the dependence between var
