The research of the petroleum geological conditions, the control factors on oil-gas, and the regularity of oil-gas distribution show that lithological reservoirs occurred in this area are of larger area and formed by stacking of multi-layer petroliferous beds which controlled by structure and lithology.
According to reciprocity principle, when adjusting the delay time of neighboring element of a receiver array and stacking the shifting signals of different elements, the received stacking energy can also be maximal in certain direction when waveforms satisfy in-phase stacking.
The work in this paper includes research on traditional 2-Dimension Pilot Symbol Assisted Modulation(2D-PSAM) and its improved algorithms, a simple channel estimation algorithm for MIMO-OFDM system on Correlation of Pilot Sequences and MIMO channel estimation using Superimposed Training.
During the fabrication of intrinsic Josephson junctions (IJJs) with Bi2Sr2CaCu2O8+δ(BSCCO) single crystals, the superconductivity of the surface Cu-O layer is degraded because of a deposited metal film on top of the stack.
Thus, the characteristics of the surface junction consisting of the surface Cu-O double layers remarkably differ from those of the junctions deep in the stack, which will be referred to as ordinary IJJs.
Meanwhile, based on the ideas from CAP (Certified Assembly Programming) and SCAP (Stack-based Certified Assembly Programming), a reasoning framework was built to verify the properties of object code in a Hoare style.
Optimization of a fuel cell stack fueled by hydrogen-based mixtures
A through-calibration algorithm is described that helps obtain the Stokes matrices for each pixel of a CCD camera with allowance for the entire stack of optical elements.
Simultaneous introduction of multiple genes into plants is a critical step in plant genetic engineering to manipulate multiple functional genes in metabolic engineering and trait stacking.
Twinning plays important roles in HCP metals and those FCC metals with low stacking fault energy.
It is found that there were high-density dislocations and stacking fault substructure in the Cu clusters that forms the obstacle of the dislocation motion, which should be the dominant reason of strengthening in the Fe-Cu alloy.
This indicates that a stacking-type mechanism underlies actinomycin intercalation into DNA.
The reason for its appearance was considered to be either the formation of a charge transfer complex between ThDP and tryptophan (phenylalanine) residue or stacking interaction between the residues of aromatic amino acids.
