Abstract In this paper, we introduce modied degenerate polyexponential Cauchy (or poly-Cauchy) polynomials and
numbers of the second kind and investigate some identities of these polynomials. We derive recurrence relations
and the relationship between special polynomials and numbers. Also, we introduce modied degenerate unipolyCauchy polynomials of the second kind and derive some fruitful properties of these polynomials. In addition,
positive associated beautiful zeros and graphical representations are displayed with the help of Mathematica. More >

Abstract Clustering analysis identifying unknown heterogenous subgroups of a population (or a sample) has become
increasingly popular along with the popularity of machine learning techniques. Although there are many software
packages running clustering analysis, there is a lack of packages conducting clustering analysis within a structural
equation modeling framework. The package, gscaLCA which is implemented in the R statistical computing
environment, was developed for conducting clustering analysis and has been extended to a latent variable modeling.
More specifically, by applying both fuzzy clustering (FC) algorithm and generalized structured component analysis
(GSCA), the package gscaLCA computes membership prevalence and item response probabilities… More >

Abstract The combination of Precision Point Positioning (PPP) with Multi-Global Navigation Satellite System (MultiGNSS), called MGPPP, can improve the positioning precision and shorten the convergence time more effectively
than the combination of PPP with only the BeiDou Navigation Satellite System (BDS). However, the Inter-System
Bias (ISB) measurement of Multi-GNSS, including the time system offset, the coordinate system difference, and
the inter-system hardware delay bias, must be considered for Multi-GNSS data fusion processing. The detected
ISB can be well modeled and predicted by using a quadratic model (QM), an autoregressive integrated moving
average model (ARIMA), as well as the sliding window strategy… More >

Abstract Personal protective equipment (PPE) donning detection for medical staff is a key link of medical operation safety guarantee and is of great significance to combat COVID-19. However, the lack of dedicated datasets makes the scarce research on intelligence monitoring of workers’ PPE use in the field of healthcare. In this paper, we construct a dress codes dataset for medical staff under the epidemic. And based on this, we propose a PPE donning automatic detection approach using deep learning. With the participation of health care personnel, we organize 6 volunteers dressed in different combinations of PPE to simulate more dress situations… More >

Abstract A soft, rough set model is a distinctive mathematical model that can be used to relate a variety of real-life data. In the
present work, we introduce new concepts of rough set based on soft pre-lower and soft pre-upper approximation
space. These concepts are soft pre-rough equality, soft pre-rough inclusion, soft pre-rough belonging, soft predefinability, soft pre-internal lower, and soft pre-external lower. We study the properties of these concepts. Finally,
we use the soft pre-rough approximation to illustrate the importance of our method in decision-making for
Chikungunya medical illnesses. In reality, the impact factors of Chikungunya’s medical infection were determined.… More >

Abstract Based on the analyses of existing preference group decision-making (PGDM) methods with intuitionistic fuzzy
preference relations (IFPRs), we present a new PGDM framework with incomplete IFPRs. A generalized multiplicative consistent for IFPRs is defined, and a mathematical programming model is constructed to supplement
the missing values in incomplete IFPRs. Moreover, in this study, another mathematical programming model is
constructed to improve the consistency level of unacceptably multiplicative consistent IFPRs. For group decisionmaking (GDM) with incomplete IFPRs, three reliable sources inuencing the weights of experts are identified. Subsequently, a method for determining the weights of experts is developed by simultaneously considering… More >

Abstract Recently, Siamese-based trackers have achieved excellent performance in object tracking. However, the high speed
and deformation of objects in the movement process make tracking difficult. Therefore, we have incorporated
cascaded region-proposal-network (RPN) fusion and coordinate attention into Siamese trackers. The proposed
network framework consists of three parts: a feature-extraction sub-network, coordinate attention block, and
cascaded RPN block.We exploit the coordinate attention block, which can embed location information into channel
attention, to establish long-term spatial location dependence while maintaining channel associations. Thus, the
features of different layers are enhanced by the coordinate attention block. We then send these features separately
into… More >

Abstract The integrated energy systems, usually including electric energy, natural gas and thermal energy, play a pivotal role in the energy Internet project, which could improve the accommodation of renewable energy through multi-energy complementary ways. Focusing on the regional integrated energy system composed of electrical microgrid and natural gas network, a fault risk warning method based on the improved RelieF-softmax method is proposed in this paper. The raw data-set was first clustered by the K-maxmin method to improve the preference of the random sampling process in the RelieF algorithm, and thereby achieved a hierarchical and non-repeated sampling. Then, the improved RelieF… More >

Abstract In this paper, we considered the improved element-free Galerkin (IEFG) method for solving 2D anisotropic steady-state heat conduction problems. The improved moving least-squares (IMLS) approximation is used to establish the trial function, and the penalty method is applied to enforce the boundary conditions, thus the final discretized equations of the IEFG method for anisotropic steady-state heat conduction problems can be obtained by combining with the corresponding Galerkin weak form. The influences of node distribution, weight functions, scale parameters and penalty factors on the computational accuracy of the IEFG method are analyzed respectively, and these numerical solutions show that less computational… More >

global matrix using a transformation matrix that varies from element. Then the derivatives of Gauss integral points
are computed in parallel, the results of which can be stored in a global matrix. And a middle layer is constructed to
assemble the final stiffness matrices in parallel. The numerical example results… More >

Abstract The static aeroelastic effect of aircraft ailerons with high aspect ratio at transonic velocity is investigated in this paper
by the CFD/CSD fluid-structure coupling numerical simulation. The influences of wing static aeroelasticity and
the ‘scissor opening’ gap width between aileron control surface and the main wing surface on aileron efficiency are
mainly explored. The main purpose of this paper is to provide technical support for the wind tunnel experimental
model of aileron static aeroelasticity. The results indicate that the flight dynamic pressure has a great influence
on the static aeroelastic effect of ailerons, and the greater the dynamic pressure, the… More >

Abstract Water quality analysis is essential to understand the ecological status of aquatic life. Conventional water quality
index (WQI) assessment methods are limited to features such as water acidic or basicity (pH), dissolved oxygen
(DO), biological oxygen demand (BOD), chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N), and
suspended solids (SS). These features are often insufficient to represent the water quality of a heavy metal–polluted
river. Therefore, this paper aims to explore and analyze novel input features in order to formulate an improved
WQI. In this work, prospective insights on the feasibility of alternative water quality input variables as new
discriminant features… More >

Abstract Multi-scale object detection is a research hotspot, and it has critical applications in many secure systems. Although the object detection algorithms have constantly been progressing recently, how to perform highly accurate and reliable multi-class object detection is still a challenging task due to the influence of many factors, such as the deformation and occlusion of the object in the actual scene. The more interference factors, the more complicated the semantic information, so we need a deeper network to extract deep information. However, deep neural networks often suffer from network degradation. To prevent the occurrence of degradation on deep neural networks,… More >
