Prediction of the technical status of pipeline based on analysis

Article preview

Since 1991 till the year of 2000 more than 300 serious accidents happened in Russia. The significant part of the accidents at main pipelines was connected with electrochemical corrosion, stress corrosion cracking and microbiological corrosion. System analysis of the accident reasons cannot be given without probabilistic and statistical approach, which assumes that the reason of the accident is the combination of many influencing factors. At the same time usage of the multivariate analysis is quite complicated task due to a large amount of factors, influencing the pipelines accident rate, insufficient statistics and unauthentic documentation of the accident causes .

Повышение точности измерения влажности сыпучих материалов динамическим термовакуумным методом

Article preview

Для повышения точности измерения влажности сыпучих материалов динамическим термовакуумным методом в диапазоне свыше 20 % предложено использовать параметры температурной кривой вакуумируемой пробы, характеризующие процесс замерзания влаги в материале. Представлены аналитические соотношения, связывающие массу воды в вакуумируемой пробе до начала процесса кристаллизации с параметрами температурной кривой и начальной влажностью материала, а также результаты экспериментальных исследований, подтверждающие адекватность теоретической модели.

Ways to increase the efficiency of the use of open-pit vehicles

Article preview

The basic directions of increase of efficiency of using of quarry motor transport are analyzed: careful choice of dump truck model; development of systems of control of loading of heavy-duty dump trucks; use of new automated systems of control of quarry motor transport. The modern automated system of dispatching of mobile quarry equipment, functioning with the support of global GPS positioning system, is considered.
