Abstract The Moon is the only celestial body that human beings have visited. The design of the Earth-Moon transfer orbits is a critical issue in lunar exploration missions. In the 21st century, new lunar missions including the construction of the lunar space station, the permanent lunar base, and the Earth-Moon transportation network have been proposed, requiring low-cost, expansive launch windows and a fixed arrival epoch for any launch date within the launch window. The low-energy and low-thrust transfers are promising strategies to satisfy the demands. This review provides a detailed landscape of Earth-Moon transfer trajectory design processes, from the traditional patched… More >

Abstract Accurate precipitation nowcasting can provide great convenience to the public so they can conduct corresponding
arrangements in advance to deal with the possible impact of upcoming heavy rain. Recent relevant research
activities have shown their concerns on various deep learning models for radar echo extrapolation, where radar
echo maps were used to predict their consequent moment, so as to recognize potential severe convective weather
events. However, these approaches suffer from an inaccurate prediction of echo dynamics and unreliable depiction
of echo aggregation or dissipation, due to the size limitation of convolution filter, lack of global feature, and less
attention to… More >

Abstract The purpose of this paper is to present the class of atomic basis functions (ABFs) which are of exponential type and are denoted by . While ABFs of the algebraic type are already represented in the numerical modeling of various problems in mathematical physics and computational mechanics, ABFs of the exponential type have not yet been sufficiently researched. These functions, unlike the ABFs of the algebraic type , contain the tension parameter , which gives them additional approximation properties. Exponential monomials up to the th degree can be described exactly by the linear combination of the functions . The function… More >

Abstract An obviously challenging problem in named entity recognition is the construction of the kind data set of entities.
Although some research has been conducted on entity database construction, the majority of them are directed at
Wikipedia or the minority at structured entities such as people, locations and organizational nouns in the news.
This paper focuses on the identification of scientific entities in carbonate platforms in English literature, using the
example of carbonate platforms in sedimentology. Firstly, based on the fact that the reasons for writing literature
in key disciplines are likely to be provided by multidisciplinary experts, this paper designs… More >

Abstract In this manuscript, our goal is to introduce the notion of intuitionistic extended fuzzy b-metric-like spaces. We
establish some fixed point theorems in this setting. Also, we plot some graphs of an example of obtained result for
better understanding. We use the concepts of continuous triangular norms and continuous triangular conorms in
an intuitionistic fuzzy metric-like space. Triangular norms are used to generalize with the probability distribution
of triangle inequality in metric space conditions. Triangular conorms are known as dual operations of triangular
norms. The obtained results boost the approaches of existing ones in the literature and are supported by… More >

Abstract In this paper, natural heat convection inside square and equilateral triangular cavities was studied using a meshless method based on collocation local radial basis function (RBF). The nanofluids used were Cu-water or -water mixture with nanoparticle volume fractions range of . A system of continuity, momentum, and energy partial differential equations was used in modeling the flow and temperature behavior of the fluids. Partial derivatives in the governing equations were approximated using the RBF method. The artificial compressibility model was implemented to overcome the pressure velocity coupling problem that occurs in such equations. The main goal of this work was… More >

Abstract With the development of molecular imaging, Cherenkov optical imaging technology has been widely concerned.
Most studies regard the partial boundary flux as a stochastic variable and reconstruct images based on the steadystate diffusion equation. In this paper, time-variable will be considered and the Cherenkov radiation emission
process will be regarded as a stochastic process. Based on the original steady-state diffusion equation, we first
propose a stochastic partial differential equation model. The numerical solution to the stochastic partial differential
model is carried out by using the finite element method. When the time resolution is high enough, the numerical
solution of the… More >

Abstract To achieve the high availability of health data in erasure-coded cloud storage systems, the data update performance in erasure coding should be continuously optimized. However, the data update performance is often bottlenecked by the constrained cross-rack bandwidth. Various techniques have been proposed in the literature to improve network bandwidth efficiency, including delta transmission, relay, and batch update. These techniques were largely proposed individually previously, and in this work, we seek to use them jointly. To mitigate the cross-rack update traffic, we propose DXR-DU which builds on four valuable techniques: (i) delta transmission, (ii) XOR-based data update, (iii) relay, and (iv)… More >

Abstract In this article, we construct the generating functions for new families of special polynomials including two parametric kinds of Bell-based Bernoulli and Euler polynomials. Some fundamental properties of these functions are given. By using these generating functions and some identities, relations among trigonometric functions and two parametric kinds of Bell-based Bernoulli and Euler polynomials, Stirling numbers are presented. Computational formulae for these polynomials are obtained. Applying a partial derivative operator to these generating functions, some derivative formulae and finite combinatorial sums involving the aforementioned polynomials and numbers are also obtained. In addition, some remarks and observations on these polynomials are… More >
