Narrow Results

In this paper, the notions of L-fuzzy soft quantales and L-fuzzy soft ideals over quantales are proposed. Some properties of L-fuzzy soft quantales (ideals) related to operations of L-fuzzy soft sets are investigated. In the case of fixed parameters, order properties of all L-fuzzy soft quantales (ideals) over a given quantale are discussed. Moreover, the concept of L-fuzzy soft quantale homomorphisms is introduced. It is proved that inverse images of L-fuzzy soft quantales (ideals) under L-fuzzy soft quantale homomorphisms are L-fuzzy soft quantales (ideals). It is also proved that under some certain conditions, images of L-fuzzy soft quantales (ideals) under L-fuzzy soft quantale homomorphisms are L-fuzzy soft quantales (ideals).

Image reconstruction is a kind of signal reconstruction. It has been widely discussed to use wavelet modulus maxima to reconstruct signal. This paper extends this technique to use two-dimensional wavelet modulus maxima to reconstruct image. An image's two-dimensional wavelet modulus maxima at various scales can compose a wavelet frame. By calculating wavelet coefficients at the modulus maxima points at various scales, we can approximately compute the frame operator, and then we use frame pseudo inverse computation on the frame operator to reconstruct image. Example shows it can efficiently reconstruct image.

With the advances in technology underpinning the design of armaments, unmanned combat platform has been developing rapidly in recent years. Using Finite Element Analysis (FEA) module of the SolidWorks software, Static and Model analysis could be performed by setting thickness of parts as variables, to study the stress distribution and natural frequencies, so as to obtain the optimal design, in terms of reliable performance for frame structural and lightweight frame.

For a cleaning frame with an engine, a loading and restraint scheme is proposed and the stress and deformation of the whole frame under low cycle rotation rate is analyzed, based on ANSYS software. The maximum stress and strain during the working process are obtained, and the variation rule for the maximum stress is discovered. According to the analysis result, the design for cleaning frame is optimized.
