Technologies of the Spot Condenser Micro-Welding of High-Temperature Thermocouples
We offer the technologies of the spot condenser micro-welding of high-temperature thermocouples made of refractory thermo-galvanic materials (tungsten rhenium, molybdenum monocrystals, etc.). Welding product is manufactured through putting the modulated current impulse into the attached vibration field of compression force.
Effective Constructive Decisions about Reconstruction, Expansion and Strengthening of the Highway Bridges
Wedeveloped an effective reconstruction system of the existing bridges with the expansion of the span clearance by different types of reinforced concrete imposed slab with protruding consoles without the extension of pillar. At the same time the beams are strengthened by the change of their static scheme from freely leaned to rigid or completely strangulated beam on pillars at the maximum preservation of the existing structures and provision of clearance and capacity required by the current design regulations of the new bridges.
Reinforced Concrete Prefabricated Domes Built without Scaffolding
These domes are designed for temple construction. Their installation is supposed to be conducted without scaffolding. The domes structure is ribbed and consists of prefabricated rib-less reinforced concrete slabs of double curvature and rigid reinforced frames for reinforced concrete monolithic meridian and end ribs, which perceive all the loads during the installation.
Monolithiation of the ribs is conducted gradually from the bottom up to top till the height of annular ribs after installing the prefabricated slabs between them.
New Constructive and Technological Systems for Housing and Other Private Construction
Collapsible frame of the new structure is developed to solve the problems of the affordable low-rise private housing construction, a significant decrease of its value (2-3 times), and construction and commissioning period.
New Composite Constructions of Bridges for Difficult Construction Conditions
New constructions are designed to solve the problems of road and urban transport due to the traffic intensity grow, especially in suburban areas of the cities with dense housing, and taking into account the possible need to accelerate the pace of construction of the bridges, flyovers, trestles and multilevel transport interchanges, at presence of difficult construction conditions using absolutely new constructive and technological decisions.
Lightweight Reinforced Concrete Constructions of the Ceilings with High-Tensile Fiberglass Reinforcement of the New Generation
The use of fiberglass reinforcement with 115 kN/cm2 strength along with the concrete of S55/60 class and more, in the tensile region allows to significantly reduce the construction weight, its cost, and to improve the reliability and durability.
Hashing Processors Based on SHA-1 Algorithm
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
he development is based on specification of theSHA-1 hashing algorithm(FIPS180-1). Processed data block size is 64 bits. WISHBONE SlaveRev.B.1 interfacewith separate 32-bit input/output buses. The development is represented as a technologically independent VHDL-model.
Processors of Symmetric Block Encryption Based on Triple Des Algorithm
They are used as a part of specialized information security systems, and as a part of devices for universal systems, e.g. in personal computers, connected to the global and local area networks.
Characteristics
The development is based onDES encryption standard (FIPS 46-3). ECB,CBC,CFB,OFBmodes are available. Processed data block size is 64 bits. Key size is 2х56 bits. The development is represented as a technologically independent VHDL-model.
