Abstract.Earthquakes threaten human survival with powerful destructive power, and the performance of buildings in earthquakes is crucial. The seismic design of traditional building structures has the limitations of non-uniform response to displacement and acceleration, which can easily lead to partial damage to the building, unreasonable structure and difficulty in post-earthquake repair, which seriously affects the comfort and safety of the building. It is emphasized that improving the seismic safety of buildings is not only an inevitable requirement to ensure the safety of people's lives, but also to … Read more →

Abstract.This paper presents a numerical simulation of a tiltrotor aircraft developed in the United States, examining the aerodynamic interference between the rotors, wings, and fuselage in three flight conditions: forward flight, transition mode, and hover. The study investigates the distribution of the velocity field, pressure field, vorticity field, and streamlines around the aircraft at different rotor tilt angles. Read more →

Abstract.Aiming at the interference problem between the tool and the surface during the contact between the blade position and the composite material during the off-line programming scraping process of aviation composite parts, the contact effect of the blade during the scraping process of the composite surface is discussed, and a rotation projection attitude optimization strategy is proposed. Firstly, by constructing the mathematical model of the contact between the scraper and the surface, the geometric properties of the scraper and its contact on the surface are analyzed. Then, the non-uniform … Read more →

Abstract.At present, the main problems in each stage of teachers' professional development can be summarized from internal and external causes. The internal causes are weak consciousness of independent development, lack of professional knowledge and ability, lack of scientific research, and lack of teaching reflection spirit. The external causes are the lack of team cooperation resources, the lack of personalized training in the education sector and the heavy burden of non-teaching. Growth thinking can fully drive the internal power of teachers, stimulate the internal potential of teachers, and … Read more →

Abstract.In the context of the digital age, data privacy and security issues are increasingly prominent. Blockchain technology plays an important role in data sharing due to its transparency and immutability, but it also brings the risk of privacy leakage. Zero knowledge proof technology provides a solution for verifying data correctness without exposing data content, which is particularly important for blockchain as it can ensure the validity and compliance of transactions while protecting user privacy. Although zero knowledge proof is quite mature in theory, its application in blockchain systems … Read more →

Abstract.Due to the pursuit of economic benefits and the development and damage to the environment, the need to develop new energy sources is increasing day by day. as one of the earliest and most mature new energy generation methods, wind power has received much attention. However, wind power generation system is constrained seriously by the environment because of the random fluctuation of wind power itself. It is easy to cause problems such as low power generation efficiency and fast device loss due to the influence of wind instability. At the same time, it is difficult to store and connect electric … Read more →

Abstract.Compressive strength is one of the important indexes to test the mechanical properties of concrete. The compressive strength of recycled composite concrete after high temperature is studied by single factor experimental analysis and double factor experimental analysis. Combined with variance analysis, the influence of replacement rate of recycled aggregate, volume incorporation amount of polypropylene fiber and volume incorporation amount of nani CaCO3 on compressive strength of recycled concrete after high temperature was systematically studied. The results show that when the replacement rate … Read more →

Abstract.In this work, first principles DFT calculations has been employed with anharmonic phonon scatter theory and Boltzmann transport method to perform a exhaustive study on the thermoelectric properties as electronic and phonon transport of layered Cs2O crystal. The results indicate that Cs2O crystal represents a flat-and-dispersive type band structure, which returns a high power factor. In the other hand, low lattice thermal conductivity is discovered in Cs2O semiconductor, combined with its high power factor, the Cs2O crystal is considered a promising thermoelectric material. It is demonstrated … Read more →

Abstract.In order to study the effects of prefabricated pore-fracture on the mechanical properties, crack extension and energy evolution of rocks under uniaxial compression, the effects of rock samples containing pore-fracture deep grey sandstone on the mechanical properties, crack extension and energy evolution of rocks were analysed in detail through the indoor experimental inverse performance of the fine-scale mechanical parameters of the PFC3D model. The results show that the mechanical parameters of deep grey sandstone samples with pore fissures are significantly lower than those of intact … Read more →

Abstract.Based on the confidentiality and efficiency of arbitration, the dispute resolution method is often agreed as arbitration in the contracts involving private equity funds. The investment process of private equity funds often involves multi-layer nesting to avoid regulation and infringement of investors' rights and interests. Such infringement cases involve joint infringement by a majority of people, and it is difficult for investors to claim their rights through infringement lawsuits based on the exclusionary effect of a valid arbitration agreement on jurisdiction in the event that investors … Read more →
