Zhundong coal is rich of alkali metals, and coal ash contains large amounts of Na and K element, which can easily lead to slagging and contamination problems, and affect the normal operation of the boiler. This paper focused on the slagging character

The ratcheting effect of the liner wall structure in the thrust chamber of liquid rocket engine under cyclic load is studied, and its service life is predicted. Firstly, the 3-D heat transfer analysis of the wall of the thrust chamber is carried out

We present two sharp empirical Bernstein inequalities for symmetric random matrices with bounded eigenvalues. By sharp, we mean that both inequalities adapt to the unknown variance in a tight manner: the deviation captured by the first-order $1/\sqrt

Abstract Cerebral venous sinus thrombosis (CVST) is a rare and devastating complication of inflammatory bowel disease (IBD). Early diagnosis and prompt treatment could improve prognosis. The aim of our study was to investigate the clinical data and p

Combining the existing slat cusp extension with the noise reduction technique proposed in this paper, based on the 30P30N multi-segment aerofoil, unsteady flow of three-dimensional airfoil structure is simulate by DDES algorithm.Firstly, the pressure

Testing by betting has been a cornerstone of the game-theoretic statistics literature. In this framework, a betting score (or more generally an e-process), as opposed to a traditional p-value, is used to quantify the evidence against a null hypothesi

Slat aerodynamic noise is largely dependent on its structure parameters(geometric position and variable outline). The analysis of the effects of these two parameters on the features of flow and aerodynamic noise for an airfoil is an effective method

Leading edge slat configurations can affect the flow field features of multi-element airfoil, and also have an impact on the distributions of slat noise sources. Based on LES(large eddy current simulation) simulations and FW-H integration equation, t

Although it is not rare in research to consider Heidegger’s thoughts in the light of the relationship between theory and practice, Heidegger behaves himself against this dichotomy. In order to understand Heidegger’s criticism of this dichoto

We present new concentration inequalities for either martingale dependent or exchangeable random symmetric matrices under a variety of tail conditions, encompassing now-standard Chernoff bounds to self-normalized heavy-tailed settings. These inequali
