New knowledge on the temperature-entropy saturation boundary slope of working fluids

Energy, 2017
The slope of temperature-entropy saturation boundary of working fluids has a significant effect on the thermodynamic performance of cycle processes. However, for the working fluids used in cycles, few studies have been conducted to analyze the saturated slope from the molecular structure and mixture composition.

Information Entropy Analysis of Rainfall Deformation of Talus Slope

Advanced Materials Research, 2011
The large talus landslide of is very complicated and difficult to deal with. In order to make a good research on the influence of rainfalls to the high talus slope deformation, the method of information entropy is employed by using the principle of information transfer and relativity to analyze and calculate the rainfall influence on the deformation ...

An adaptive slope entropy combined with hierarchical entropy applied to rolling bearing fault diagnosis

Structural Health Monitoring
This article proposed an improved slope entropy (Islope) algorithm. In the original algorithm, the state mode is determined by parameters α and β. However, the wide range of parameter choices and strong randomness in the original algorithm may decrease slope entropy capability when unreasonable parameters are selected.

Entropy dissipation scheme and minimums‐increase‐and‐maximums‐decrease slope limiter

International Journal for Numerical Methods in Fluids, 2011
SUMMARYIn this paper, we continue to study the entropy dissipation scheme developed in former. We start with a numerical study of the scheme without the entropy dissipation term on the linear advection equation, which shows that the scheme is stable and numerical dissipation and numerical dispersion free for smooth solutions.

Applicability of the permutation largest slope entropy to strange nonchaotic attractors

Nonlinear Dynamics, 2016
We extend the permutation largest slope entropy (PLSE) to the detection of strange nonchaotic attractors (SNA). The initial time series derived from a quasi-periodically forced chaotic map is first transformed into a series of symbols using the order relation.
