2014The positional order correlation length « 03BE~ » parallel to the smectic (Sm) layers in the G, F and C phases of HBHA (7O.6) has been measured by X-ray diffraction. In the Sm-G phase its value is limited by crystallite size and lies between 1200-1500 A. At the Sm-G to -F transition 03BE ~ changes from 300 to 180 A with a temperature dependence predicted by a dislocation mediated melting mo...

Smart contracts refer to small programs that run in a decentralized blockchain infrastructure. The system is trustless, and the determination of common variables done by consensus between peers. Developing applications require generating random becomes significantly challenging—for instance, lotteries, games, assignments. Many number generators (RNGs) for smart have been developed environment. ...

Smart contracts are Turing-complete programs running on the blockchain. They immutable and cannot be modified, even when bugs detected. Therefore, ensuring smart bug-free well-designed before deploying them to blockchain is extremely important. A contract defect an error, flaw or fault in a that causes it produce incorrect unexpected result, behave unintended ways. Detecting removing defects ca...

This paper addresses OFDM (orthogonal frequency division multiplexing) transmission over optical links with high spectral efficiency, i.e. by using high-order QAM-modulation schemes as a mapping method prior to the OFDM multicarrier representation. Here we address especially coherent optical OFDM modem in long distance. Numerical simulations of the coherent optical orthogonal frequency division...

A new mathematical model for the capacitated multi-facility location-allocation problem with probabilistic customers' locations and demands is developed in this paper. The model is formulated into the frameworks of the expected value model (EVM) and the chance-constrained programming (CCP) based on two different distance measures. In order to solve the model, two hybrid intelligent algorithms a...
