The aim of the present paper is to define and study (IC)$LM$-fuzzytopological spaces, a generalization of (weakly) induced $LM$-fuzzytopological spaces. We discuss the basic properties of(IC)$LM$-fuzzy topological spaces, and introduce the notions ofinterior (IC)-fication and exterior (IC)-fication of $LM$-fuzzytopologies and prove that {bf ICLM-FTop} (the category of(IC)$LM$-fuzzy topological ...

Target maneuver trajectory prediction plays an important role in air combat situation awareness and threat assessment. To solve the problem of low accuracy traditional method model, a target model based on phase space reconstruction-radial basis function (PSR-RBF) neural network is established by combining characteristics with time continuity. In order to further improve performance rival penal...

Generalized frequency division multiplexing (GFDM) is one of the candidate waveforms beyond 5G for wireless communication. Channel estimation challenging in transmission because inherent interference. It based on a pilot signal that uses Least Square (LS) and Normalized Mean (NLMS) to perform estimation. This paper used Artificial Neural Network (ANN) as channel method, considered novel process...

We describe and analyse Levenberg–Marquardt methods for solving systems of nonlinear equations. More specifically, we first propose an adaptive formula for the Levenberg–Marquardt parameter and analyse the local convergence of the method under Hölder metric subregularity. We then introduce a bounded version of the Levenberg–Marquardt parameter and analyse the local convergence of the modified m...

Hard turning has replaced conventional grinding in production processes recent years as an emerging technique. Nowadays, coated carbide tools are replacing expensive CBN inserts turning. Wear is a significant concern when with carbide; it immediately affects the acceptability of machined surface, which causes machine downtime and loss due to wastage parts. Online tool condition monitoring (TCM)...

The composition of self-compacting concrete (SCC) contains 60–70% coarse and fine aggregates, which are replaced by construction waste, such as recycled aggregates (RA). However, the complexity its structure requires a time-consuming mixed design. Currently, many researchers studying prediction properties using soft computing techniques, will eventually reduce environmental degradation other ma...

Gaussian decomposition of images leads to many promising applications in computer graphics. Gaussian representations can be used for image smoothing, motion analysis, and feature selection for image recognition. Furthermore, image construction from a Gaussian representation is fast, since the Gaussians only need to be added together. The most optimal algorithms [3, 6, 7] minimize the number of ...
