CALCIUM OXALATE: A SURFACE TREATMENT FOR LIMESTONE

Calcium Oxalate: A Surface Treatment for Limestone

This paper looks at the bar drain board artificially induced surface conversion of calcium carbonate to the more durable calcium oxalate.Extensive research is being carried out on wall paintings and marble sculpture at the Opicificio delle Pietre Dure e Laboratori di Restauro in Florence, Encouraged by their work, I have researched the effectivenes

A Remote Sensing Image Fusion Method Combining Low-Level Visual Features and Parameter-Adaptive Dual-Channel Pulse-Coupled Neural Network

Remote sensing image fusion can effectively solve the inherent contradiction between spatial resolution and spectral resolution of imaging systems.At present, the fusion methods of remote sensing images based on multi-scale transform usually set fusion rules according to local feature information and pulse-coupled neural network (PCNN), but there a
