Strategic instruments for the growth of the industrial sector of the economy in the conditions of the sixth big Kondratiev cycle

An analysis of global trends in economic and technological development shows that there are all signs that the driving force behind the rise of the sixth major Kondratiev cycle has started working – digital technologies of the fourth technological order, which is initiated by the emergence and implementation of innovations in production processes, defi ned as NBIC technologies (convergence of four industries knowledge related to nanotechnologies, biotechnologies, information and cognitive technologies). However, the currently observed slowdown in economic growth rates (both global and national) leads to the need to fi nd growth points, the fi xation and development of which would make it possible to extract the maximum benefi t from the use of digital technologies. The purpose of this article is to identify tools that can ensure the progressive development of the industrial sector of the national economy in the conditions of the predicted crisis and recession.The article analyzes the dynamics of the world’s leading economies, shows that the industrial growth index is dominant in the formation of the gross domestic product of the national economy. It is suggested that one of the key factors infl uencing the slowdown in economic growth is the “digital divide” – the period of time that passes after the emergence of technologies on the market and the beginning of their commercial operation. To eliminate the “digital divide”, it is proposed to use digital platforms that provide the possibility of confl ict-free evolutionary redesign of existing enterprise processes and intelligent integration of implemented solutions in a single information space, due to which there is a signifi cant increase in effi ciency and production growth. At the same time, it is noted that, unlike previous technological paradigms, the modern economy is characterized by the possibility of using digital solutions of equal functionality at enterprises of various industries, it is only necessary to set up routes for the execution of end-to-end business processes, taking into account the specifi cs of production. Examples of a universal corporate digital platform that solve such problems are given.

Trends in development of agricultural aerial photography technology

Aerial photography is becoming an integral part of remote sensing in digital agriculture. The first aerial photographs were taken in the mid-19th century. (Research purpose) The paper aims to retrospectively analyze the evolution of aerial photography equipment for capturing agricultural lands, beginning with the creation of the first aerial photograph up to the present day. (Materials and methods) A historical-analytical approach was employed to examine the existing literature. Within this study, the development of agricultural aerial photography equipment was categorized into four distinct time periods: 1885-1908, 1909-1945, 1946-1979, and from 1980 to the present day. (Results and discussion) In the initial phase of experimental aerial photographic equipment development, significant advancements were achieved, encompassing the emergence of the first photograph, the creation of portable cameras and their adaptation for use with hot air balloons and kites, rockets, and birds. Technological growth in the first half of the 20th century contributed to elevating aerial photography to a versatile tool applied for a wide range of intelligence operations, including agricultural tasks. The evolution of space technologies in the second half of the 20th century resulted in the rapid development of both aerial photography equipment and their carriers. This progress facilitated the use of color aerial photography for the examination of the Earth's surface. The advancements of digital technologies at the end of the 20th century and the beginning of the 21st century facilitated the use of high-resolution digital aerial cameras mounted on various carrier platforms, ranging from unmanned aircraft to artificial Earth satellites. (Conclusions) A retrospective analysis reveals that the development and creation of equipment for aerial photography of agricultural lands unfolded in a sporadic fashion. This progression was closely intertwined with global political, social, and economic situation, as well as the state of technological advancement in related areas. Over the coming decade, the sustained application of aerial photography in agriculture is poised to enhance the efficiency of unmanned aircraft, reduce the production costs associated with aerial photography, and facilitate the widespread adoption of digital remote sensing technology within the agricultural sector.

Oxidation to spontaneous combustion of pyrophoric iron sulphides in the process industries: A review

In the fossil energy industries, pyrophoric iron sulphides (PISs), the most commonly mentioned pyrophoric material, are widely distributed in the exploitation, transportation, storage, refining equipment and piping of oil and natural gas. When equipment and piping are opened for inspection or maintenance, they may be exposed to air and act as an ignition source by undergoing an exothermic reaction. Accordingly, they become hot or incandescent and can ignite nearby inflammable hydrocarbon-air mixtures.Numerous researchers have performed various research into this area. There are four main interests involved in this regard, and they are listed as follows: (1) the physical and chemical properties of PISs, (2) the suitable condition, processes, and mechanism for oxidation to spontaneous combustion of PISs, (3) the spontaneous combustion risk assessment of PISs, and (4) the active/passive prevention technologies and strategies of spontaneous combustion of PISs.Moreover, the main drawbacks existing in past research are also highlighted. Correspondingly, several solutions are put forward in combination with the current research methods, technology development trends, and industrial practice requirements. By the thorough summary, it is expected to lay a foundation and direct further research into the oxidation to spontaneous combustion of PISs, as well as to better enrich the theoretical basis and technical support for the improvement of production safety management levels in the petroleum, natural gas, and coal chemical industry.

Research on the capacity allocation optimization of micro-grid considering wind-PV-ES

To achieve the goal of “2030 carbon peak and 2060 carbon neutralization” and optimize the form of multi-energy utilization in the industrial park, it is very important to fully exploit distributed clean energy and micro-grid energy system in the park. In view of the economy of micro-grid investment, the capacity proportion of wind, solar and energy storage is the key point in the planning and design stage. A capacity allocation optimization strategy of micro-grid considering wind/solar/thermal/energy storage is proposed. The model takes the minimum total cost of the system as the objective function. As the characteristics of load in the industrial park has a poor adjust ability, the energy storage is added to the integrated energy allocation system as a flexible adjustable power supply. The energy capacity allocation of micro-grid in a cement plant park in China is analysed and calculated in this paper. The results show that after the completion of wind power, photovoltaic and thermal power, the annual power generation of the project will increase by about 105540 MWh, save about 31000 tons of standard coal per year, and reduce about 84000 tons of carbon dioxide emissions. As the cost of renewable energy will be further reduced under the sustainable development of clean energy and the trend of future technology development, establishing a clean energy micro-grid in the industrial park can bring considerable economic benefits. This study can provide a reference for the capacity allocation of the energy system in the industrial park at the planning stage.

Research on operation characteristics and control strategy of hybrid multi-feed HVDC system

Flexible DC transmission technology based on voltage source converter (VSC-HVDC) and high voltage DC transmission technology based on grid commutation converter (LCC-HVDC) have complementary characteristics, so the hybrid DC technology combined with LCC-HVDC and VSC-HVDC can make them complement each other and become the development trend of power grid technology in the future. In the existing hybrid multi-infeed DC system, conventional DC transmission (LCC-HVDC) and flexible DC transmission (VSC-HVDC) operate independently and are not coordinated with each other, but there is a blank in the research on the protection coordination relationship between VSC/LCC parallel DC hybrid system and its near area AC system. Therefore, it is necessary to theoretically analyse and study the operation characteristics, control strategy and protection coordination relationship between near-area AC systems of hybrid multi-infeed HVDC systems. Due to the limited space, this paper mainly analyses the operation characteristics and control strategy of hybrid multi-infeed HVDC system, and verifies the correctness of the theory through simulation research. In the next step, the corresponding protection is configured in the above simulation model, and the protection adaptability analysis and protection optimization scheme of hybrid multi-infeed HVDC system are obtained.

Research on instrument structure scheme for improving the sensitivity of wireline D-T source porosity logging

Utilizing a D-T source to replace the chemical source is the development trend of nuclear logging technology. However, the wireline porosity logging with a D-T source has a lower sensitivity. To solve this problem, the key factors on the sensitivity of neutron porosity logging are analyzed. Combining the numerical simulation method, special structures such as neutron-source deceleration block and detector shielding sleeve are designed to improve the sensitivity of D-T source wireline porosity logging tool, and the detector-spacing selection of the improved instrument was discussed. Study indicates that the sensitivity of neutron porosity logging mainly depends on the fast-neutron deceleration length, the proportion of formation information in the detector count and the detector-spacing. In the instrument design, the tungsten neutron-source deceleration block is adopted to reduce the energy of neutrons emitted by source, thereby shortening the fast-neutron deceleration length and improving the logging sensitivity. Additionally, the detector shielding sleeve made of boron carbide can absorb thermal neutrons from the borehole to increase the proportion of formation information in the detector count, which can also effectively improve the sensitivity. Based on the above structure design, it was found that when the near detector-spacing was set at 30 cm and the far detector-spacing was set at about 70 cm, the performance of the instrument can reach the best. This study can provide theoretical guidance for the application of D-T source in the wireline porosity logging tool in the future.

A Fast Acquisition Algorithm for Hybrid Signals of 5G and BeiDou B1

With the large-scale use of BeiDou navigation and 5G technology worldwide, integrating BeiDou navigation and communication has become a hot research topic in navigation and positioning technology. Low-cost, miniaturized, and susceptible mixed-signal receivers will become the future receiver technology development trend. However, the current receiver technology still faces the challenge of further improving the positioning service capability and communication quality, which includes the lack of practical analysis of the compatibility between signals and the lack of mixed-signal processing capability of the receiver baseband key technology. To address these problems, we start by analyzing the signal part of 5G out-of-band signals falling into the BD B1 signal band, conduct a detailed analysis of the mixed signal regime and frequency planning, and design a hybrid receiver architecture compatible with both signals, and propose an SC-PMF-FFT fast capture algorithm based on strong correlation, which takes advantage of the strong correlation of signals broadcast on the BD B1 frequency point from B1I to B1C, and reuses the structure of the CDMA system signal capture algorithm to complete the fast capture of 5G signals using an OFDM system. The experiments show that the method can capture the BeiDou B1 signal with a sensitivity of −154 dBm and a whole constellation capture time of no more than 40 ms with the inlet power of the 5G signal not exceeding −45 dBw.
