Database processing

In relational and object-oriented database systems, fuzzy or uncertain data will always be naturally present. However, these systems have many limitations for handling complex data types of fuzzy nature. Therefore, to represent and process fuzzy data, they need a flexible and efficient fuzzy query system. To solve this challenge, this paper proposes two different approaches to increase the flexibility of the fuzzy interrogation system.

A Luoi is a mountainous district of Thua Thien Hue province, Vietnam, with rugged terrain, steep slopes, and many valleys. A Luoi district bears many risks of natural disasters such as storms, floods, droughts, and landslides yearly. This study applied the AHP (Analytical Hierarchy Process) model with the GIS tool on the input database of Sentinel-2B Image, DEM, and geographic background data to evaluate the influence of 5 factors: slope, elevation, aspect, land cover, and vegetation to generate a landslide hazard zoning map, scale 1:50,000.

Ebook "Observational astrophysics (Third edition)" focuses on fundamental and sometimes practical limitations on the ultimate performance that an astronomical system may reach, rather than presenting particular systems in detail. Avoiding particulars, it covers the whole of the electromagnetic spectrum, and provides an introduction to the new forms of astronomy becoming possible with gravitational waves and neutrinos. It also treats numerical aspects of observational astrophysics: signal processing, astronomical databases and virtual observatories.
