Classification Of Oil Products According To The Nomenclature Of Goods, Kurbankul Mavlankulovych Karimkulov Profesor, Azoda Abdurahmanova Dec 2023

Classification Of Oil Products According To The Nomenclature Of Goods, Kurbankul Mavlankulovych Karimkulov Profesor, Azoda Abdurahmanova

Technical science and innovation

The article analyzes types of vegetable oils. Simple methods of determining their quality using liquid gas chromatography have been developed. Recommendations for improving the classification of foreign economic activity based on commodity nomenclature were developed and recommended for customs operations. “Fats and oils of animal, vegetable or microbiological origin and products of their breakdown; prepared edible fats; waxes of animal or vegetable origin” was called. Animal fats, including pork, beef, sheep, goat, fish and oils of animals such as marine mammals are classified according to the Nomenclature of Foreign Economic Activities of the Republic of Uzbekistan in commodity headings 1501-1506 …


Expansibility Classification Of Mudstone For High-Speed Railway Ballastless Track Foundation, Yan-Jin Xue, Qi-Cai Wang, Li-Na Ma, Rong-Ling Zhang, Jin-Peng Dai, Qiang Wang Feb 2021

Expansibility Classification Of Mudstone For High-Speed Railway Ballastless Track Foundation, Yan-Jin Xue, Qi-Cai Wang, Li-Na Ma, Rong-Ling Zhang, Jin-Peng Dai, Qiang Wang

Rock and Soil Mechanics

Red mudstone is a typical Jurassic sedimentary rock. It contains trace clay minerals, which is easy to soften in water, disintegrate when dehydrated, and has a certain swelling property. Red mudstone is an important factor that causes the continuous uplift of the sub- grade for the Lan-Xin high-speed railway. Therefore, it is of great significance to redefine the expansibility of this kind of soil for the design and construction of ballastless track of high-speed railway. For this reason, the equivalent smectite content, cation exchange capacity, free expansion rate and liquid limit are selected as the indicators of mudstone expansion. The …


Features Of Designs Of Nanosenses For The Oil Industry, A.E. Vorobev, Zhang Lianzi Oct 2019

Features Of Designs Of Nanosenses For The Oil Industry, A.E. Vorobev, Zhang Lianzi

Gorniy vestnik Uzbekistana

Development of design features of nanosensors for oil branch is shown. It is established that in modern nanosensors usually influence formation of a working signal as environment qualitative quantitative indices (values of temperature, pressure, speed of migration of fluids, contents of chemical elements, sizes рН, etc.) and the nature (predetermining properties), structure and extent (the geometrical sizes) of nanoparticles of sensitive elements which the studied environment influences, forming as a result this working signal. The basic design of nanosensors and the mechanism of their work is described. Distribution of nanosensors on classes depending on the principles and mechanisms of action …


Two-Class Classification With Various Characteristics Based On Kernel Principal Component Analysis And Support Vector Machines, Ivanna Kristianti Timotius, Iwan Setyawan, Andreas Ardian Febrianto Apr 2011

Two-Class Classification With Various Characteristics Based On Kernel Principal Component Analysis And Support Vector Machines, Ivanna Kristianti Timotius, Iwan Setyawan, Andreas Ardian Febrianto

Makara Journal of Technology

Two class pattern classification problems appeared in many applications. In some applications, the characteristic of the members in a class is dissimilar. This paper proposed a classification system for this problem. The proposed system was developed based on the combination of kernel principal component analysis (KPCA) and support vector machines (SVMs). This system has been implemented in a two class face recognition problem. The average of the classification rate in this face image classification is 82.5%.
