Relationship network

Mô hình CSDL là phương thức biểu diễn các dữ liệu, giúp cho việc tổ chức các dữ liệu thuận tiện cho việc thiết kế, lưu trữ, xử lý Mô hình CSDL dùng mô hình toán học để mô tả CSDL dựa trên các tập hợp và phép toán Các mô hình CSDL phổ biến: Mô hình phân lớp (hierarchical model) Mô hình mạng (network model) Mô hình quan hệ (relational model) Mô hình thực thể-liên kết (entity-relationship model) Mô hình hướng đối tượng (object model) Mô hình XML – bán cấu trúc (semi-structural model)...

In this study, MCS is applied to compute the reliability of the nodes and the network under uncertain demand and roughness, and to determine how reliability is distributed among the various nodes of WDN, as well as assessing the reliability of the network as a series or parallel system. The effect of the resilience index on the nodal and network reliability is also assessed.

This research investigates the relationship between post fault transient overvoltages and the functionality of the digital distance protection. The study is conducted in a 66kV network with a neutral earth resistor as method to earth the power system. This paper begins by performing an extensive power system analysis on ground fault transient overvoltages. The study is conducted by using the PSCAD-EMTC software package.

In this paper, we present a novel global protein-protein interaction network alignment algorithm, which is enhanced with an extended large neighborhood search heuristics. Evaluated on benchmark datasets of yeast, fly, human and worm, the proposed algorithm outperforms state-of-the-art algorithms. Furthermore, the complexity of ours is polynomial, thus being scalable to large biological networks in practice.
