    Neighborhood Search Based Improved Bat Algorithm for Web Service Composition

    Fadl Dahan1,2,*

    Computer Systems Science and Engineering, Vol.45, No.2, pp. 1343-1356, 2023, DOI:10.32604/csse.2023.031142

    Abstract Web services are provided as reusable software components in the services-oriented architecture. More complicated composite services can be combined from these components to satisfy the user requirements represented as a workflow with specified Quality of Service (QoS) limitations. The workflow consists of tasks where many services can be considered for each task. Searching for optimal services combination and optimizing the overall QoS limitations is a Non-deterministic Polynomial (NP)-hard problem. This work focuses on the Web Service Composition (WSC) problem and proposes a new service composition algorithm based on the micro-bats behavior while hunting the prey.… More >

    Energy-Related Services as a Business: Eco-Transformation Logic to Support the Low-Carbon Transition

    Oleksandr Kovalko1, Tatiana Eutukhova2, Oleksandr Novoseltsev3,*

    Energy Engineering, Vol.119, No.1, pp. 103-121, 2022, DOI:10.32604/EE.2022.017709

    Abstract The transition to low-carbon development has been recognized as one of the most important directions for the transformation of national economies in most countries. Today we can identify two of the most common service-oriented logical models of this transition. These are models of Service-Dominant Logic and Product-Service Systems that are used in this study to create a service-oriented platform for stimulating business development in the field of energy-related (ER) services. The establishment of such a platform is being considered based on the conceptual provisions of the global business ecosystem. Such a platform has been found… More >

    Epidemiologic Evolution Platform Using Integrated Modeling and Geographic Information System

    Adrian Brezulianu1, Oana Geman2,*, Muhammad Arif3, Iuliana Chiuchisan2, Octavian Postolache2, Guojun Wang3

    CMC-Computers, Materials & Continua, Vol.67, No.2, pp. 1645-1663, 2021, DOI:10.32604/cmc.2021.014225

    Abstract At the international level, a major effort is being made to optimize the flow of data and information for health systems management. The studies show that medical and economic efficiency is strongly influenced by the level of development and complexity of implementing an integrated system of epidemiological monitoring and modeling. The solution proposed and described in this paper is addressed to all public and private institutions involved in the fight against the COVID-19 pandemic, using recognized methods and standards in this field. The Green-Epidemio is a platform adaptable to the specific features of any public… More >

    Numerical Optimization Algorithm for Unsteady Flows of Rotor Based on Web Service

    Jilin Zhang1,4,5, Xuechao Liu1,5, Jian Wan2,1,5, Yongjian Ren1,5, Binglin Xu1,5, Jianfan He1,5, Yuchen Fan1,5, Li Zhou1,5, Zhenguo Wei6, Juncong Zhang6, Jue Wang3

    Intelligent Automation & Soft Computing, Vol.25, No.3, pp. 527-546, 2019, DOI:10.31209/2019.100000109

    Abstract A numerical optimization algorithm for unsteady flows of rotor based on web service is proposed. Space discretization uses the finite volume method, time discretization uses the implicit dual-time steps method, and turbulence model uses the Spalart–Allmaras (S–A) model. In order to efficiently use the computing resources of the cluster, a service-oriented service computing architecture is used in a parallel computing service program. In order to realize the load balance of hybrid grid partition, the grid is partitioned by Metis Library. Meanwhile, data communication based on Message Passing Interface (MPI) technology guarantees the consistency of convergence More >
