The annual increase in installation capacity and electrical production of renewable energy sources, primarily wind turbine generators (WTG), is shaping a renewable energy dominated power system.WTGs are susceptible to the temporary overvoltage caused by reactive power surplus following low-voltage ride through (LVRT).This can lead to the large-scal
New Rapid and Robust Color Image Watermarking Technique in Spatial Domain
In this paper, a novel spatial Door Mirror domain color image watermarking technique is proposed to rapidly and effectively protect the copyright of the color image.First, the direct current (DC) coefficient of 2D-DFT obtained in the spatial domain is discussed, and the relationship between the change of each pixel in the spatial domain and the cha
Pengembangan Modul IPA Braille Berbasis Integrasi Islam dan Sains
This study aims at developing a Braille module based on Door Mirror the integration of Islam and science in elementary school.The study uses the rating scale sheet as the instrument.Experts are requested to asses the learning modules.In addition, three students with disabilities are asked to give their response to the learning module.The quantitati
Individual Tree Parameters Estimation for Chinese Fir (Cunninghamia lanceolate (Lamb.) Hook) Plantations of South China Using UAV Oblique Photography: Possibilities and Challenges
Chinese fir (Cunninghamia lanceolate (Lamb.) Hook) individual tree parameters extraction is important for scientific forest management.However, high-precision parameters extraction by field investigation or spaceborne optical remote sensing is difficult when the forest is dense and the terrain is complex.This article proposes a framework for extrac
