Influence of El Niño on parameters of the middle and upper atmosphere over Eastern Siberia according to reanalysis and model data in winter

One of the most important climate-forming phenomena in the ocean—atmosphere system is the El Niño Southern Oscillation (ENSO) events, which manifest themselves with varying intensity in almost all regions of the globe. The central regions of Eurasia are farthest from the tropics of the Pacific Ocean, the regions where ENSO originates. There are different points of view regarding the nature of the ENSO effect on these regions. In the presented work, the influence of ENSO on the upper atmosphere of the Northern Hemisphere and, in particular, on the upper atmosphere of Eastern Siberia is estimated using model calculations and reanalysis data. The results of the analysis show that the large-scale structures of the atmospheric response to the ENSO events in the Northern Hemisphere are similar according to modeling and reanalysis, yet the regions of Eastern Siberia are on the periphery of the main signal and there are significant differences in estimated effects from one case of El Niño and La Niña to another. In January, ENSO has the greatest impact on the middle atmosphere of the polar regions of the Northern Hemisphere. Over Eurasia and Eastern Siberia, the atmospheric response to the ENSO events turned out to be weak or absent

Сжатие графической информации с использованием тематических текстур

To decorate surface of terrain thematic textures are used. It is supposed that observer is not often interested in the exact photographic information about the wide areas covered, for instance, by forest, water, etc., so that the benefits of photographic texture can be obtained by composing a number of patterns called "themes" to produce a final texture of the specific area. The goal of using thematic textures is to abolish the need of the global area texture, and additionally, animation features become available by simple means

Класифікація методів антиаліайзингу

У роботі проведено аналіз існуючих методів антиаліайзингу зображень і запрпопоновано їх класифікаціюThe purpose of this paper is to analyze the existing methods Anti-Aliasing and try the most common classification methods, including methods of Super-Sampling, Multy-Sempling and post-processing methods, which also relate to methods Anti-Aliasing. The basic principle of Anti-Aliasing - a " make low-contrast " sharp boundaries between colors in order to achieve the visual effect of a smooth transition between tones. Different requirements for tools Anti-Aliasing based on tasks performed by computer systems encourage manufacturers to develop graphical tools with different specifications and characteristics for maximum satisfaction of needs subject area. This creates a need to develop classification methods Anti-Aliasing to determine the optimal method and its adaptation to the tasks used

Текстурный процессор для систем визуализации реального времени

Рассматривается  архитектура  текстурного  процессора  для  компьютерных  систем  визуализации  реального  времени.  Предложенный  в  данной  работе  подход  позволил  создать  универсальную  архитектуру  текстурного  процессора.  Заложенные  в  архитектуру  процессора  возможности позволяют генерировать высокореалистичные текстурированные грани, работать с различными форматами текстур, а также проводить  аппаратную декомпрессию сжатых текстур.We consider the architecture of texture processors for computer systems visualization of real time. Proposed in  this  paper  an  approach  to  create  a  universal  architecture  texture  processor.  Incorporated  into  the  architecture  of  the  processor capabilities allow  to generate highly realistic  textured  face with a variety of  formats,  textures, and conduct a  hardware decompression of compressed textures.

Methodological Approaches to Assessing the Economic Damage Associated with the Incidence of Hemorrhagic Fever with Renal Syndrome in the Russian Federation

The aim of the study was to develop methodological approaches to assessing the economic damage associated with the incidence of hemorrhagic fever with renal syndrome (HFRS) and to calculate the economic damage by the example of an outbreak of HFRS in the Saratov region in 2019. Materials and methods. The paper analyzes the economic indicators of the Federal State Statistics Service; data on the incidence of HFRS in the Russian Federation for the period of 2019–2022. To calculate the cost of outpatient and inpatient medical care, as well as the costs associated with the medical follow-up of convalescents, the indicators of the Program of state guarantees of free provision of medical care to citizens for 2022 and for the scheduled period of 2023 and 2024 were used. The calculation of economic losses associated with the payment of temporary disability benefits was carried out according to the equation provided in the Federal Law No. 255-FZ dated December 29, 2006 (as amended on October 07, 2022). Economic losses associated with premature death at an economically active age were calculated based on the value of unproduced GDP due to lost years of life in the corresponding age group. Results and discussion. The costs of treatment, rehabilitation and payment of temporary disability benefits for 1 case of HFRS at the age of 0 to 56.5 years for the female population and from 0 to 61.5 years for the male population amount to 140 495 rubles; over the age of 56.5 years for the female population and 61.5 years for the male population – 95 412 rubles, respectively. Each fatal case of HFRS aged 0 to 16 years among the male population costs the state 38 976 231 rubles; among the female population – 34 708 331 rubles; in active working age – the value of economic damage varies depending on the age of the person who died of HFRS. The economic damage of the outbreak of HFRS in the Saratov Region (2019), taking into account the direct expenditures of the healthcare system and indirect losses of the country’s economy amounted to 441 453 432 rubles. It is of note that the structure of the main damage is dominated by indirect losses in the economy caused by the premature death of people in economically active age
