Abstract:

An oil dust indicator is a crucial component in maintaining the efficiency and longevity of machinery and engines. It serves the dual purpose of monitoring both oil level and contamination levels, particularly from dust and particulate matter. The indicator typically consists of a sensor, a processor unit, and a display or alert mechanism. The sensor, often a combination of optical and pressure sensors, continuously monitors the oil. clarity and level. When dust or other contaminants accumulate in the oil, the sensor detects changes in clarity and triggers an alert. The processor unit interpre

Abstract:

The paper presents studies of the main physical and chemical indicators of the operation of synthetic oils. The following indicators were determined: kinematic viscosity at 100°C, viscosity index (IV); general base indicator, mg KOH/1g of oil, ignition temperature in an open crucible, °C, absolute density, g/cm3 (at t° at 20°C), dynamic viscosity and sulfonated ash content (%). In addition, comparative studies of the technical and economic indicators of regulatory and technical maintenance when changing engine oil were carried out.

Abstract:

The great demand for oil shale resource development and the corresponding threats to the environment have resulted in the urgent need to assess the impact of oil shale in situ mining on the environment. In this paper, based on an analysis method developed by the previous literature and the Delphi technique, three secondary indicators and ten tertiary indicators were selected. The weights of the indicators at all levels were subsequently calculated. The results identify environmental capacity, groundwater risk and prevention, and cleaner production as having the largest weights in the indicator

Abstract:

The price fluctuations in the crude oil market remarkably influence the global economy since crude oil is an essential source of energy and plays a determinant role in most industrial sectors. The tremendous development of social media has generated many applications that can be used for sentiment analysis to improve the prediction of crude oil prices. Many researchers have also used technical indicators to predict oil prices. This study integrated several machine learning approaches—random forest, support vector machine, and long short-term memory—with a dynamic expanding moving window and fi

Abstract:

Transformer is an indispensable equipment in the power system, and its normal operation plays a vital role in the stable operation of the power system and power quality. However, due to the complexity of the working environment of the transformer, its internal structure is also more complex, so the transformer failure frequency is higher. Therefore, timely detection and early warning of transformer failure is of great importance. In this paper, a machine learning algorithm is introduced to automatically discover the laws and patterns in the data by learning and analysing a large amount of data

The ISM stages begin with identifying indicators, compiling contextual relationships, compiling reachability matrices, compiling level partitions, compiling digraphs, and compiling ISM models. Then MICMAC analysis is used to group each of these indicators into four categories based on their driving power and dependence power. In this study, 16 hands of agile supply chain management

Crude oil, as the most traded commodity in the world, exhibits prices with a clear influence on other commodities in the worldwide market. It also poses implications regarding the economic growth of oil-exporting and oil-importing nations. This study provides an unprecedented method of employing the indicator approach as proposed by the Conference Board, National Bureau of Economic Research, to construct a leading indicator for the global crude oil price. The results reveal that the constructed oil price indicator can predict the cyclical movement of the oil price by moving in advance of 3.5 m

Abstract International Oil Companies (IOC’s) had been playing a major role in oil industry at the beginning of 20th century. They had many volatility during last century and faced with many obstacles which forced them to change their business models and improve their outcome to satisfy their shareholders. One of the most important challenges was oil nationalization in oil producer countries which were happened by establishment of NOCs. Later green energy issue which came from CO2 emission problem happened and recently, oil and gas price diminish challenges, involve all IOCs with the most impor

Abstract:

Introduction. One of the main types of deposits in an internal combustion engine is an emulsion or sludge formed by water, decomposition of fuel residues and solid residues. The sludge usually settles on the colder surfaces of the engine, such as the bottom of the crankcase pan, valve chambers and upper boards. The main problem is that this type of deposits can be collected by the engine oil and transferred to areas such as the oil pump, intake valve or oil channels, where the sludge can interfere with the flow of oil and cause a failure of the lubrication mode. In addition to the disruption i

Abstract:

The purpose of the study was to evaluate the performance of large domestic and foreign oil and gas companies based on a factor analysis of the return on equity in the context of financial and economic crises. The relevance of the topic is due, on the one hand, to the leading role of the oil and gas industry in the Russian economy, and, on the other hand, to the need develop modern tools for the assessment and prediction of the performance of companies and comparison of the results of economic activity with those of foreign competitors. The object of the study was the financial performance of t

Abstract:

The generalized indicator of useful use, depending on the state of individual elements of oil-producing equipment, characterizes the ability of this equipment to perform its function during operation at optimal working time. The generalized indicator of the useful use of operational equipment can be described as the calculated sum of the indicator of the useful use of individual equipment elements. If, during operation, the oil-producing equipment retains its operability due to frequent replacement of its structural and non-structural elements, then such operational equipment is considered by

Abstract:

As oil spills cause harm to the survival and environment of the ocean, the objective of the present paper is to study the oil migration range using the key indicator kv, which is defined as the ratio of oil spill speed to ocean current speed. The correctness of diffusion models created and estimated for subsea oil spills can be verified by experiments. We also considered the effect of key indicators on the horizontal and vertical dispersion ranges of oil spills. The study’s findings show that, under various kv settings, the horizontal and vertical spreading heights of oil spills both increase

Petroleum-derived substances (PDSs) pollutants negatively affect agricultural soil biocenosis, disturbing the biological properties of soils. This paper aimed to test the effect of oil derivatives during soil bioremediation processes on Steinernema feltiae nematode and determine their potential use as an indicator of the degree of soil pollution. Two test series were applied (with bioremediation and without bioremediation) in which the soil was contaminated with diesel fuel, petrol and engine oil. A preparation was designed for the bioremediation of soils polluted with oil derivatives and used

The evaluation quality rating of hot-rolled pipes using complex quality indicators is considered. The weighted averages of arithmetic and geometric complex indicators as well as with probabilistic indicators of access to allowable intervals on the example of oil-grade pipes are compared. It is shown that all the indicators have similar values. A complex rating of the properties of pipes manufactured by current and improved technologies was conducted. The impact of individual indicators on the quality of pipes as a whole was estimated. A comparison of complex indicators of the quality of pipes
