Orientation‐based edge‐colorings and linear arboricity of multigraphs

Finally, we show that the (g,h) u2010oriented chromatic index is always equal to its list coloring analogue.

Artificial neural network and dataset optimization for implementation of linear system models in resource‐constrained embedded systems

In situations where real time data are needed for model preparation, On u2010board or on-u2010board training is extremely useful. Considering the model's functionality parameters, such as model parameters, memory specifications, precision, and processing time, it is expected that the model be mounted on commercially available microcontrollers with very little on-board memory. For increased success, minimum data requirements for creating ANN models of linear systems are also investigated. When Bayesian Regularization training function is used alongside Log Sigmoid Activation, it is shown that for linear systems, 1u20133u20131 architecture achieves best results against u2264100 data points. According to the results, averaging with 25 data points results in overu2010all higher results than other datasets. A large dataset requires more training time and memory, while a smaller dataset achieves less accuracy. Clustered data and uniformly distributed results are also explored.

Simultaneous inference for linear mixed model parameters with an application to small area estimation

Linear mixed models have drew significant interest in various areas of applied statistics over the past two decades. Despite that, statistical methods for comparing simultaneous inference for mixed parameters are rare. For example, there is an interest in a comparative analysis of cluster-u2010level variables or subject-specific estimates in studies with repeated measurements. Given a linear mixed model, we discuss the appropriateness of simultaneous inference. Specifically, we design simultaneous prediction intervals as well as multiple testing procedures for mixed parameters. We're using a consistent bootstrap approximation of the delivery of max-u2010type statistics to build our machines.

Deciphering the Role of (Anti)Aromaticity in Cofacial Excimers of Linear Acenes

As key examples of polycyclic aromatic hydrocarbons, we examine some of the latest findings of unprecedented aromatic stability in spin singlet excimer and through u2010space aromatic form in triplet excimer and through-u2010space aromatic character in a series of linear [n]acenes. The antiaromaticity of the sandwich spin singlet and triplet benzene excimers was also investigated by decomposing the excimer wave function as a linear combination of local exciton and charge transfer diabats, as well as determining their contribution to the nucleus independent chemical shift of the two six-member rings.

Overcoming non‐convexity of the robust nonlinear output feedback problem: An adaptive linear matrix inequality solution

This paper discusses a novel approach for adaptive output feedback of uncertain nonlinear structures; it employs nonlinear control and observation loops to propel a time-variant function as a Lyapunov one, ensuring asymptotic stability of the system states and measurement error.

Numerical Study of Non‐linear Buckling Analysis for Steel and Partial Concrete Encased Composite Columns

The new Eurocodes effectively constrain engineering designs that can be directly ported to classical structural analysis, but many of them do not adequately describe advanced numerical methods. The present study examines the buckling analysis of steel and partial encased composite columns. The residual stresses are based on prEN1993[2] and ECCS U2013 Pub. The goal is to review non-u2010linear finite element analysis, as well as the impact of additional reinforced concrete encasements. The numerical analysis of steel and composite columns is being developed by a guidance.

A method for estimating the aging state of lithium‐ion batteries based on a multi‐linear integrated model

Summary The state of the lithium-u2010ion battery's stability is a key parameter in the battery control scheme. We provide a new SOH estimation scheme in this paper based on incremental capacity estimation and empirical mode decomposition, as well as a gated recurrent unit for fitting. We first integrate IC curves and real characteristics from the input feature map and use EMD to identify high-frequency capacity regeneration fluctuations. The feature maps are integrated into the DAG-u2010GRU framework to accommodate multiple EMD decomposition steps and build SOH prediction models, which are compared to other neural network prediction tools, which are compared with different neural network prediction methods. SOH's minimum mean square error and mean absolute error of SOH are reduced to 0. 65 and 1. 6 percent, respectively, according to the experimental findings, which also exhibits excellent generalization capabilities.
