An overview of key stages in nanotechnology progress and the world nanoindustry market development has been carried out. A comprehensive analysis of patents, including the growth rate of numbers of patent applications from 2001 to 2014; patent distributions between countries, institutes, and companies; and a compilation of main areas in patent protection is given. The main part of the review is devoted to trends in three primary clusters in nanoindustry: nanomaterials, nano(opto)electronics, and nanomedicine. Characteristics of the most interesting products and technologies in the main fields of interest are presented, including classification, market value, and main applications.
Every year, the production of quantum computers is becoming more productive and cheaper - for example, “The Tsuchongzi” computer uses 56 qubits and is able to solve problems that highlight the possibility of quantum acceleration within a few hours, while classical supercomputers require tens of thousands of years. Currently, IBM allows any Internet user to remotely connect and work on a real quantum computer, albeit with a power of several qubits. Modern cryptography is based on the fact that it is difficult to carry out factorization of integers or discrete logarithm by classical algorithms. But with the use of Shor's algorithm on a quantum computer, these difficulties are easily bypassed. Some of the most popular cryptographic systems - RSA (integer factorization), DH (discrete logarithm), and ECDSA (elliptic curves over finite fields) - will no longer be a reliable tool for data encryption with the advent of productive quantum computers. In this article, post-quantum cryptographic systems are studied and compared with the classical RSA system.
Protecting from the action of radio of hindrances on the elements of zenithal rocket complex of shorter-range is one of important problems, that requires modern approach for her decision. Presently, influence of active hindrances is certain yet not enough on possibilities of armament on the defeat of air aims. In the article the analysis of influence of hindrances of different closeness is conducted on the station of accompaniment of aims of fighting machine of zenithal rocket complex shorter-range. The partial model of determination of index is offered hindrance of stability of the station of accompaniment of aim of zenithal rocket complex of shorter-range. The brought partial model over allows an analytical method to conduct the evaluation of values of conditional hit of model aim probabilities under various conditions. Mathematical calculations are conducted for: amplification of aerial of accompaniment of aim of fighting machine and aerials factors hindrance of producer; powers of hindrances on the entrance of accompaniment of aim of fighting machine; to the maximum sensitiveness of accompaniment of aim of fighting machine and relations hindrance/noise in the radio-location channel of accompaniment of aim; standard deviation of error of aiming of rocket depending on distance to the point of meeting of rocket with an aim in the zone of defeat taking into account influence of hindrances on the radio-location channel of accompaniment of aim of fighting machine; probabilities of passing of rocket in the «tube» of the set radius and conditional hit of aim probability at firing by one rocket; coefficient of зпомеха stability of accompaniment of aim of fighting machine; to conditional hit of aim probability hindrance of producer at firing by two rockets. On the accepted entry informative parameters and technical descriptions of accompaniment of aim of fighting machine certainly her maximum sensitiveness and relation hindrance/noise in this radio-location channel. On results mathematical calculations (mathematical design) corresponding charts that over is brought are got. From charts it is possible to define high efficiency of firing rockets on a model (air) aim.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
