Changes in the quality of feedstocks generated by involving various petroleum fractions catalytic cracking significantly affect catalyst deactivation, which stems from coke formed on surface. By conducting experimental studies and catalysts, as well using industrial data, we studied how content saturates, aromatics resins (SAR) feedstock main process variables, including temperature, consumptio...

Helicobacter pylori is a gram-negative, spiral-shaped, microaerophilic organism that colonizes the stomach of humans and causes chronic-active gastritis, peptic ulcer disease, and gastric cancers, including adenocarcinoma of the stomach and MALT (mucosal-associated lymphoid tumor) lymphomas. H. pylori colonizes the stomach of over 50 % the world’s human population, primarily those who reside in...

This paper focuses on the selection of matching areas in gravity-aided inertial navigation system. Firstly, Sobel operator was used convolution gravity anomaly map to obtain feature map. The slope parameters were constructed by combining and characteristic parameters, such as difference between rows columns, variance map, pooling difference, range combined. Based support vector machine algorith...
