 ABSTRACT

 The article considered the issue of cleaning big data before uploading it to storage. At this time, the errors made and the methods of eliminating these errors have been clarified.

The technology of creating a big data storage and analysis system is reviewed, as well as solutions for the implementation of the first stages of the Data Science process: data acquisition, cleaning and loading are described. The results of the research allow us to move towards the realization of future steps in the field of big data processing.

It was noted that Data cleansing is an essential step in working with big data, as any analysis based on inaccurate data can lead to erroneous results.

Also, it was noted that cleaning and consolidation of data can also be performed when the data is loaded into a distributed file system.

The methods of uploading data to the storage system have been tested. An assembly from Hortonworks was used as the implementation. The easiest way to upload is to use the web interface of the Ambari system or to use HDFS commands to upload to HDFS Hadoop from the local system.

It has been shown that the ETL process should be considered more broadly than just importing data from receivers, minimal transformations and loading procedures into the warehouse. Data cleaning should become a mandatory stage of work, because the cost of storage is determined not only by the amount of data, but also by the quality of the information collected.  

Keywords: Big Data, Data Cleaning, Storage System, ETL process, Loading methods.

ABSTRACT

The article is devoted to the development of technology for obtaining organic-mineral fertilizers and chemical meliorants on the basis of solid waste (SW). The presented article mainly describes the physico-chemical basis of decomposition of solid waste with solutions of different percentages of sulfuric acid, which is the first stage of the study. The purpose of the research is to study the physico-chemical basis of decomposition of solid waste depending on the concentration of sulfuric acid solution, its initial temperature, time and intensity of mixing during the development of technology for obtaining organic-mineral fertilizers and ameliorative substances.

During the study, the concentration of sulfuric acid solution from 5% to 70, decomposition dynamics of samples within 36-80 minutes, It was studied under mixing conditions at an intensity of 40 per/min to 180 per/min. It was established that each factor has a great influence on the percentage of decomposition of solid household waste, therefore, the optimal parameters for each factor were determined and clarified as a result of experimental experiments.

As a result of the conducted research, it was determined that solid waste from the point of view of the richness of macro-and microelements contained in it is a fully usable raw material for fertilizer production, it has been observed that the extraction of food-repellent elements from the composition of solid household waste with 10-20% sulfuric acid solution is appropriate and in this case, along with the decomposition, the process of neutralization of microorganisms in it takes place. 40-60⁰C optimum temperature of technological process for transition of moisture-repellent elements into solution, it has been proved that the concentration of acid solution is between 10-20% and the mixing intensity is 60-140  per/min., in the end, it is recommended to enrich the composition of the obtained fertilizer with nutritive substances after the completion of the technological process in order to improve the quality of the composition of the obtained liquid fertilizer.

As a result of the conducted studies, it was found that during the decomposition of solid waste in the presence of weak acid solutions, about 80-85% of the nutrient elements contained in it can be extracted and used in fertilizer production.

Keywords: fertilizer, solid waste, sulfuric acid, ameliorant, salinity, salinization.

 ABSTRACT

 Gas lifts are versatile, dependable lifting systems that provide numerous options. This article discusses typical problems with gas lift valves used in geotechnical applications. What could result in such operational and well-related flaws. A closed system powered by high pressure gas is a gas lift system. Gas lifts are frequently adaptable, dependable lift systems with a variety of manufacturing options. For all operations, adding gas from an outside source lowers the fluid pressure level, which forces more fluid to be kept in conditions with high water retention. Excellent product quality, changeable gas lift complex, and lift depth. Where possible, involuntary injection gas tensions and volumes are extremely rare and can support various synthetic buoyancy types. By lowering the fluid's pressure stages with the use of an extraterrestrial gas penthouse, more fluid may be stored in the Force as the descent goes on. As you alter the parameters, consider how other elements alter. The behavior of gas lift valves is predicted using a variety of techniques. These techniques additionally consider additional factors. The Thornhill-Craver equation is the formula most frequently used to forecast the performance of throttle valves. The interpretation of gas lift taps is overestimated by the Thornhill-Craver equation, particularly for big ports, according to Gerberding and Acuna. Gas lifts are not appropriate for combined liquids, supersaturated Neptune, or thick, abrasive paintings. , which focuses on how to increase the performance of weak gas lift taps, highlighting the necessity of their complicated design, does not function well for grabbing old wells or extending inflow lines with external internal compasses.

 ABSTRACT

 The article dedicated  "Submerged arc welding and meltıng technology" method, which is one of the technologies for repairing friction-worn parts of oil and gas equipment.

The efficiency, technological regime,advantages of the process are noted, and it is also shown that this method is used today in the oil industry and shipbuilding.

With these methods, the repairing of a part of the pieces corroded by friction, as well as the possibility of welding steel plates of different grades and thicknesses, was reflected.

In determining welding procedures for certain applications, the welding engineer must first take into account the specific welding qualities required, since in practice, although some factors can be determined quite accurately, others change during manufacturing process.

Arc voltage, electrode selection, welding speed are important considerations in determining operating mode, and the penetration caused by high voltage combined with low speed is indicated accordingly.

The supply of agent (glycerin) to the recently created attachment zone is indicated. It reduces the thermal impact of the cooling arc on the half and will increase the cooling rate of the deposited and metal, decreasing the deformation and self-heating of the adjacent elements of the half. Besides, the liquid serves to safeguard the liquid metal from the harmful effects of chemical element and gas.

Keywords: overheating, vibration, crack, arc voltage, welding defects, welding speed, technical glycerin, soda ash.
