Abstract Serious uneven settlement of the tunnel may directly cause safety problems. At this stage, the deformation of the
tunnel is predicted and analyzed mainly by numerical simulation, while the commonly used finite element method
(FEM) uses low-order continuous elements. Therefore, the accuracy of tunnel settlement prediction is not enough.
In this paper, a method is proposed to study the vertical deformation of the tunnel by using the combination
of isogeometric analysis (IGA) and Bézier extraction operator. Compared with the traditional IGA method, this
method can be easily integrated into the existing FEM framework, and ensure the same accuracy. A numerical… More >

Abstract Isogeometric analysis (IGA) is introduced to establish the direct link between computer-aided design and analysis.
It is commonly implemented by Galerkin formulations (isogeometric Galerkin, IGA-G) through the use of
nonuniform rational B-splines (NURBS) basis functions for geometric design and analysis. Another promising
approach, isogeometric collocation (IGA-C), working directly with the strong form of the partial differential
equation (PDE) over the physical domain defined by NURBS geometry, calculates the derivatives of the numerical
solution at the chosen collocation points. In a typical IGA, the knot vector of the NURBS numerical solution is only
determined by the physical domain. A new perspective… More >

Abstract Problems: For people all over the world, cancer is one of the most feared diseases. Cancer is one of the major
obstacles to improving life expectancy in countries around the world and one of the biggest causes of death before
the age of 70 in 112 countries. Among all kinds of cancers, breast cancer is the most common cancer for women.
The data showed that female breast cancer had become one of the most common cancers. Aims: A large number of
clinical trials have proved that if breast cancer is diagnosed at an early stage, it could give patients more… More >

Abstract After the excavation of the roadway, the original stress balance is destroyed, resulting in the redistribution of stress
and the formation of an excavation damaged zone (EDZ) around the roadway. The thickness of EDZ is the key
basis for roadway stability discrimination and support structure design, and it is of great engineering significance
to accurately predict the thickness of EDZ. Considering the advantages of machine learning (ML) in dealing with
high-dimensional, nonlinear problems, a hybrid prediction model based on the random forest (RF) algorithm is
developed in this paper. The model used the dragonfly algorithm (DA) to optimize two hyperparameters… More >

Abstract This study investigates the scheduling problem of multiple agile optical satellites with large-scale tasks. This problem
is difficult to solve owing to the time-dependent characteristic of agile optical satellites, complex constraints, and
considerable solution space. To solve the problem, we propose a scheduling method based on an improved sine
and cosine algorithm and a task merging approach. We first establish a scheduling model with task merging
constraints and observation action constraints to describe the problem. Then, an improved sine and cosine
algorithm is proposed to search for the optimal solution with the maximum profit ratio. An adaptive cosine factor
and… More >

Abstract With the rapid development of deep learning, the size of data sets and deep neural networks (DNNs) models are also
booming. As a result, the intolerable long time for models’ training or inference with conventional strategies can
not meet the satisfaction of modern tasks gradually. Moreover, devices stay idle in the scenario of edge computing
(EC), which presents a waste of resources since they can share the pressure of the busy devices but they do not.
To address the problem, the strategy leveraging distributed processing has been applied to load computation tasks
from a single processor to a group of… More >

Abstract This paper discusses the significance and prospects of low altitude small satellite aerial vehicles to ensure smooth
aerial-ground communications for next-generation broadband networks. To achieve the generic goals of fifthgeneration and beyond wireless networks, the existing aerial network architecture needs to be revisited. The detailed
architecture of low altitude aerial networks and the challenges in resource management have been illustrated in
this paper. Moreover, we have studied the coordination between promising communication technologies and low
altitude aerial networks to provide robust network coverage. We talk about the techniques that can ensure userfriendly control and monitoring of the low altitude aerial… More >

Abstract Most developing countries such as Afghanistan, Pakistan, India, Bangladesh, and many more are still fighting
against poliovirus. According to the World Health Organization, approximately eighteen million people have
been infected with poliovirus in the last two decades. In Asia, still, some countries are suffering from the virus.
The stochastic behavior of the poliovirus through the transition probabilities and non-parametric perturbation
with fundamental properties are studied. Some basic properties of the deterministic model are studied, equilibria,
local stability around the stead states, and reproduction number. Euler Maruyama, stochastic Euler, and stochastic
Runge-Kutta study the behavior of complex stochastic differential equations. The… More >

Abstract The ablation of ultra-high-temperature ceramics (UTHCs) is a complex physicochemical process including
mechanical behavior, temperature effect, and chemical reactions. In order to realize the structural optimization
and functional design of ultra-high temperature ceramics, a coupled thermo-chemo-mechanical bond-based
peridynamics (PD) model is proposed based on the ZrB2 ceramics oxidation kinetics model and coupled thermomechanical bond-based peridynamics. Compared with the traditional coupled thermo-mechanical model, the
proposed model considers the influence of chemical reaction process on the ablation resistance of ceramic materials.
In order to verify the reliability of the proposed model, the thermo-mechanical coupling model, damage model and
oxidation kinetic model are… More >
