Several methods of diversity combining for a Rayleigh-faded channel are evaluated and compared. The considered are, coherent reception, maximal ratio (MRC), selection (SC), generalization SC, whereby the two (three) signals with largest amplitudes coherently combined. We will call this method second (third) order denote it SC2 (SC3). Similar techniques also investigated noncoherent equal gain (EGC) replacing MRC, versions SC3. Numerical results indicate that SC3 significantly enhances...
The average signal-to-noise ratio (SNR) of a generalized selection combining scheme, in which the m diversity branches (m/spl les/L, where L is total number available) with largest instantaneous SNRs are selected and coherently combined, derived. A Rayleigh fading channel assumed, simple closed-form expression for SNR found upper bounded by maximal combining, lower conventional combining.
To improve the wear resistance of CoCrFeNi HEA alloy for a wider range industrial applications, alloying strategy was applied to by doping Mo element in various ratios, and CoCrFeNiMox (x=0, 0.2, 0.5, 1) deposits were fabricated cold spray. The microstructure evolution, mechanical properties, tribological properties cold-sprayed systematically investigated. results showed that Mo0, Mo0.2, Mo0.5 have face-centered-cubic (FCC) single structure, while Mo1.0 deposit composed FCC matrix hard...
Cancer-associated fibroblasts (CAFs) are found in primary and advanced tumours. They primarily involved tumour progression through complex mechanisms with other types of cells the microenvironment. However, essential fibroblasts-related genes (FRG) bladder cancer still need to be explored, there is a shortage an ideal predictive model or molecular subtype for immune therapeutic assessment cancer, especially muscular-invasive based on FRG.
A selection combining scheme for a RAKE receiver operating over multipath fading channel is introduced, by which the m largest outputs are selected instead of only one, as in conventional receiver. Expressions error probability this an exponential intensity profile (MIP) with arbitrary decay constant found first deriving joint density function ordered outputs, then averaging conditional function. The performance compared that maximal ratio both interference-limited and noise-limited...
The average signal-to-noise-ratio (SNR) of a generalized selection combining (GSC) scheme, in which the m diversity branches (m/spl les/L, where L is total number available) with largest instantaneous SNRs are selected and coherently combined, derived. A Rayleigh fading channel assumed, simple closed-form expression for SNR found upper bounded by maximal ratio combining, lower conventional combining.
Composition dependence of Cu–In–Se films with nominal 60 nm thickness grown on Na-free glass substrates has been systematically investigated by Raman scattering and x-ray diffraction spectra. The most intense A1 mode shift from 175 cm−1 for Cu1.5InSe2 to 151 CuIn5Se8 indicates weakening the bond-stretching forces decrease in Cu content. According evolution phonon frequencies films, we found that bands around 160 174 observed are probably due other ordered structure phase which is very...
Polyphosphate inorganic polymer is evaluated as a high‐performance lubricant for steel/steel contacts at 600, 700, and 800 °C. In situ thermal tests of this indicate that liquid lubrication the rubbing interface occurring. Tribological testing indicates molten polyphosphate effective and, reduces friction wear sliding tribo pair substantially. The lubricated shows desirable tribological performance correlates closely with temperature‐dependent hierarchical structure tribo‐interface under...
The Internet of Things (IoT) becomes reality. But its restrictions become obvious as we try to connect solutions different vendors and communities. Apart from communication protocols appropriate identity management mechanisms are crucial for a growing IoT. recently founded Identities Discussion Group within Kantara Initiative will work on open issues manage "Identities Things" an enabler fast-growing ecosystem.
We utilise the dual synthesis strategy in terms of bimetallic inorganic building blocks and sulfur containing organic ligand. A novel sulfur-containing metal framework (Fe2Co-TPDC) with two types 4-fold meso-helical structures has been successfully synthesized. Benefitting from uniform distribution active sites structural stability mixed-metallic method, Fe2Co-TPDC can efficiently prevent a shuttle behavior endow commendable specific capacity. As far as we know, this is first time that...

Abstract The effect of grain boundary (GB) defects on the tribological properties MoS 2 has been investigated by molecular dynamics (MD) simulations. GB defects-containing during scratching process shows a lower critical breaking load than that indentation process, owing to combined pushing and interlocking actions between tip atoms. wear resistance with is relevant misorientation angle due accumulation long Mo-S bonds around GBs. Weakening adhesion strength substrate an efficient way...
Rolling mill bearings are prone to wear, erosion, and other damage characteristics due prolonged exposure rolling forces. Therefore, regular inspection of is necessary. Ultrasonic technology, its non-destructive nature, allows for measuring the oil film thickness distribution within bearing during disassembly. However, process using ultrasonic reflection coefficients determine state bearings, changes in temperature operation can occur. waves susceptible variations, different temperatures...
Osteoporosis (OP) is a prevalent bone disease characterized by reduced density and quality, increasing fragility fracture risk. Osteoclast (OC) activity circadian rhythm play role in the pathogenesis of OP. Melatonin regulator that affects metabolism, but its molecular mechanism has not been studied detail. This study aimed to identify relationship between melatonin-related genes OP through bioinformatics methods verify it experimentally.We analysed microarray data from GSE35959 dataset,...
