High Mach number limit of one-dimensional piston problem for non-isentropic compressible Euler equations: Polytropic gas [PDF]
, 2019 We study high Mach number limit of the one dimensional piston problem for the full compressible Euler equations of polytropic gas, for both cases that the piston rushes into or recedes from the uniform still gas, at a constant speed.

Intelligent Fault Diagnosis of Hydraulic Piston Pump Based on Wavelet Analysis and Improved AlexNet
Italian National Conference on Sensors, 2021 Hydraulic piston pump is the heart of hydraulic transmission system. On account of the limitations of traditional fault diagnosis in the dependence on expert experience knowledge and the extraction of fault features, it is of great meaning to explore the

Clear as black and white: the effects of ambiguous rhetoric depend on candidate race [PDF]
, 2018 Campaign advisors and political scientists have long acknowledged the benefits of ambiguous position taking. We argue, however, that these benefits do not extend to black candidates facing nonblack voters.

Numerical Investigation of Sinusoidal and Trapezoidal Piston Profiles for an IC Engine
, 2020 This paper is aimed at a comparative investigation on two different velocity profiles for piston movement namely Sinusoidal and Trapezoidal Profiles for an IC Engine. In conventional IC Engine, velocity profile of piston motion is Sinusoidal. It has many

An absolute continuity for positive operators on Banach lattices
International Journal of Mathematics and Mathematical Sciences, 1991 For positive operators on a Banach lattice, absolute contnuity conditions are considered. An operator absolutely continuous with respect to T is compared to sums of compositions of T together with orthomorphisms or in special cases projections ...

Conventional methods of piston surface treatment for IC engines
Zaštita Materijala, 2014 This paper provides an overview of conventional methods of piston surface treatment for IC engines. One of the most stressed parts of IC engine is the cylinder assembly, i.e., the piston as a component of this assembly.
