Hashing processors are used to calculate hash functions within the specialized information security systems, including systems for generation of the digital signatures and authentication systems.
Characteristics
The development is based on specification of theMD5 hashing algorithm(RFC1321). WISHBONE SlaveRev.B.1 interfacewith separate 32-bit input/output buses. The development is represented as a technologically independent VHDL-model.
Poisson pulse sequences generators (PPSG) are designed to form the pulse sequences according to Poisson distribution. PPSG are widely used in radio engineering, measuring technologies, information security systems and other areas, including simulation of random processes and information transmitting.
This development is used to heat water by hot water supply systems. The collector is combined with building's roof, which feature is that the top covering of the collector is made of corrugated roofing material of the building. This allows the reducing of the cost of solar collector, to increase its solidity and to simplify the structure.
Surface strengthening of the details of rotation bodies forms by vibration and centrifugal processing by increasing the hardness of metal and redistribution of residual stresses in it provides increased the longevity by 2-2.5 times of airplanes wheels and vehicles with discs from the magnesium and aluminum alloys. Alongside with increased reliability of disks and drums this strengthening technology allows to reduce the weight of these parts by 15-20% that improves the dynamic characteristics of cars, reliability and security of transport transportations.
The developed technology basics of vibration and centrifugal strengthening of long-length details that ensures high level of deformation energy, capable of riveting the surface layers of steel details at a depth of 0.2-0.25mm.
Strengthening of casing tubes, high pressure tubes, internal and external surfaces by vibration and centrifugal processing and allows not only to increase the strength of these details, but also to reduce theirmaterial capacity to 15-20%.
The developed technology basics involves surface strengthening of drilling pumps by vibration and centrifugal processing with simultaneous formation of carbide layer resistant to abrasive wear on them. At the same time increased hardness of metal on the working surfaces of pump sleeves in combination with the formation of wear resistant layer on them, combination of themprovides positive synergistic effect, by 1.5-2 times increases the longevity of expensive drilling pumps.
A centrifugal vibration technology basics has been created for strengthening of internal surfaces of lengthy parts, which provides increased hardness of the metal in the surface layers of the inner surface of gun barrels and forming in them favorable stress of compression.
The proposed strengthening technology is appropriate to the usage for large-calibre artillery and tank guns, drilling and casing pipes, high pressure pipes.
There is no technology analogue of centrifugal vibration strengthening of the internal surfaces of gun barrels in the world.
This is a high-performance, economically feasible and environmentally friendly technology of electrochemical processing of the secondary raw materials of tungsten (obsolete armour-piercing discarding sabots (WC-Ni), used bits of quick-cutting tools (WC-Co) obtaining the commodity sulfates of tungsten oxide, ammonium paratungstate and nickel or cobalt.
Software modules of the passive and active controllinginterference fields of the conflicting systems of electronic warfare (EW), created on basis of the analysis of the existing EW systems and evaluation of their development trends till 2026, are used to form the requirements for radio signals structures resistant to interference environment.
At the stage of water preparation we offer to carry out a preliminary cavitation processing of water for plants watering, which not only cleans the water from pollutants (including biological), but also improves the water structure bringing it closer to the most favourable for the assimilation of plant and animal world of monocrystalline state.
