Carbon capture and storage (CCS) is one of the technologies to reduce greenhouse gas emissions (GHG) tocapture of CO2 from the flue gas of a power plant that typically use coal as a Source of energy and then store it ina suitable geological storage (in specific locations). In practice, these sites may not be readily available forstorage at the same time that the Sources (GHG producing) are operating which gives rise to multi – periodplanning problems. This study presents a mathematical approach by considering constraints limit flowratereceived by Sink, various time availability of Sink and Source and calculation with the purpose to determine theminimum cost network which is getting the maximum load that is exchanged from Source to Sink. Illustrativecase studies are given to demonstrate the application of mathematical models to obtained with the exact result ofthe exchange network from Source to Sink. Derived from network obtained from the calculation of theMaximum Load Source to Sink and results may vary in accordance with the limitations that exist in themathematical model. The case study has been prepared with 2 cases, first 6 Source and 3 Sink with value ofSource Load is greater than the amount available on the Sink. Also, second case is 2 Source and 5 Sinkwithvalue of Source Load is smaller than the amount available on the Sink. In addition, Case Studies tominimize the cost of pipeline construction and distribution of CO2 by plant and storage location determination inJava. Flowrate restriction factor that goes into Sink, Source and Sink establishment time and cost are taken intoaccount can affect the networks that can be exchanged from the Source to the Sink.

The main characteristics of graphic information compression methods with losses and without losses (RLE, LZW, Huffman's method, DEFLATE, JBIG, JPEG, JPEG 2000, Lossless JPEG, fractal and Wawelet) are analyzed in the article. Effective transmission and storage of images in railway communication systems is an important task now. Because large images require large storage resources. This task has become very important in recent years, as the problems of information transmission by telecommunication channels of the transport infrastructure have become urgent. There is also a great need for video conferencing, where the task is to effectively compress video data - because the greater the amount of data, the greater the cost of transmitting information, respectively. Therefore, the use of image compression methods that reduce the file size is the solution to this task. The study highlights the advantages and disadvantages of compression methods. The comparative analysis the basic possibilities of compression methods of graphic information is carried out. The relevance lies in the efficient transfer and storage of graphical information, as big data requires large resources for storage. The practical significance lies in solving the problem of effectively reducing the data size by applying known compression methods.

Проблема обеспечения высокого качества продукции для оптимизации затрат на ее производство и хранение актуальна для производителей и переработчиков плодовых культур. Исследовано влияние обработки плодов яблок препаратами на основе 1-метилциклопропена на изменение органолептических и биохимических показателей продукции при хранении. Объектом исследования были яблоки сорта Айдаред, выращенные на территории Краснодарского края, урожая 2020 года. При подготовке к исследованию часть яблоневых насаждений в период созревания плодов обрабатывали препаратом «Румянец» на основе 1-метилциклопропена в течение 28 дней с интервалом между обработками в 7 дней. После съема часть плодов с обработанных и необработанных деревьев перед закладкой на хранение была однократно обработана 1-метилциклопропеном с концентрацией активного вещества 1,4%. Для закладки на хранение были составлены 4 образца: образец 1 – необработанные плоды яблок (контроль); 2 – яблоки, обработанные препаратом «Румянец» в период созревания; 3 – яблоки, обработанные 1-метилциклопропеном перед закладкой на хранение; 4 – яблоки, обработанные препаратом «Румянец» в период созревания и 1-метилциклопропеном при закладке на хранение. Образцы яблок хранили при температуре (2 ± 1)°С и относительной влажности воздуха 85% в течение 30 сут. Установлено, что наивысшую оценку по значимым органолептическим показателям – площадь окрашенной поверхности, основная и покровная окраска кожицы, вкус и запах получил образец яблок 2. Его биохимические показатели на момент окончания срока хранения были выше по сравнению с аналогичными показателями контрольного образца. Содержание витамина С в плодах на момент окончания хранения снизилось: в контрольном образце на 7,3%, в образце яблок, обработанных в период созревания препаратом на основе 1-метилциклопропена, – на 3,6%. Дополнительная обработка яблок препаратом 1-метилциклопропена при закладке на хранение способствовала снижению органолептических показателей качества яблок (образцы 3 и 4). The problem of ensuring high quality products to optimize the cost of its production and storage is relevant for producers and processors of fruit crops. The effect of processing apple fruits with preparations based on 1-methylcyclopropene on the changes in the organoleptic and biochemical parameters of the products during storage was studied. The object of the study was apples of the Aydared variety grown on the territory of the Krasnodar region, the harvest of 2020. In preparation for the study, a part of apple plantations during the fruit ripening period was treated with the preparation «Rumyanets» based on 1-methylcyclopropene for 28 days with an interval between treatments of 7 days. After fruit picking, part of the fruits from the treated and untreated trees were treated once with 1-methylcyclopropene with a concentration of the active substance of 1.4% before being stored. 4 samples were prepared for storage: sample 1 – unprocessed apple fruits (control); 2 – apples treated with the preparation «Rumyants» during the ripening period; 3 – apples treated with 1-methylcyclopropene before storage; 4 – apples treated with the preparation «Rumyants» during the ripening period and 1-methylcyclopropene before storage. Apple samples were stored at a temperature of (2 ± 1)°C and relative humidity of 85% for 30 days. It was found that the highest score for significant organoleptic parameters – the area of the painted surface, the main and cover color of the skin, taste and smell had the sample of apples 2. Its biochemical parameters at the end of the storage period were higher than those of the control sample. The content of vitamin C in fruits at the end of storage decreased: in the control sample by 7,3%, in the sample of apples treated during maturation with a preparation based on 1-methylcyclopropene – by 3,6%. Additional treatment of apples with 1-methylcyclopropene preparation before storage contributed to a decrease in the organoleptic quality indicators of apples (samples 3 and 4).
