Semantic Difference in ALN

چکیده
We study the semantic difference operator defined in [16] for ALN . We give a polynomial-time algorithm to compute it. We compare it with the syntactic difference operator defined in [7], for which we also give a polynomial-time algorithm for ALN .

بررسی تاثیر کلرید آمونیوم (NH4Cl) و اندازه ذرات پودر آلومینیوم در تولید ویسکرهای نیتریدآلومینیوم(AlN) بهروش نیتریداسیون مستقیم
In this study, AlN whiskers were prepared in a tube furnace at 1000˚C for 1h with 500 nitrogen gas flow. Al powders with particle size of 3 μm and 45 μm and NH4Cl were used as raw materials. SEM, TEM and XRD analysis were used to characterize AlN whiskers. The results showed that the diameters of AlN whiskers would range from 140 nm to 340 nm if different amounts of NH4Cl and 3 μm Al p...
متن کاملThermal and electrical conductivity of Aluminium Nitride nanofluids
This study was designed to experimentally measure the thermal and electrical conductivities of Aluminium Nitride/Ethylene Glycol (AlN/EG) nanofluids. Transmission electron microscopy (TEM) was used to characterize the shape of AlN nanoparticles. Nanofluids with different particle volume concentrations of 0.5%, 1%, 2%, 3%, 4%, and 5% were utilized. The thermal and electrical conductivities of the...
متن کاملEffect of Thickness on Structural and Morphological Properties of AlN Films Prepared Using Single Ion Beam Sputtering
Aluminum nitride (AlN) thin films have potential applications in microelectronic and optoelectronic devices. In this study, AlN thin films with different thicknesses were deposited on silicon substrate by single ion beam sputtering method. The X-ray diffraction (XRD) spectra revealed that the structure of films with thickness of - nm was amorphous, while the polycrystalline hexagonal AlN with a...
متن کاملCharacterizing the Semantics of Terminological Cycles in ALN Using Finite Automata
The representation of terminological knowledge may naturally lead to terminological cycles. In addition to descriptive semantics , the meaning of cyclic terminologies can also be captured by xed-point semantics, namely, greatest and least xed-point semantics. To gain a more profound understanding of these semantics and to obtain inference algorithms as well as complexity results for inconsisten...
متن کاملBand offsets of non-polar A-plane GaN/AlN and AlN/GaN heterostructures measured by X-ray photoemission spectroscopy
The band offsets of non-polar A-plane GaN/AlN and AlN/GaN heterojunctions are measured by X-ray photoemission spectroscopy. A large forward-backward asymmetry is observed in the non-polar GaN/AlN and AlN/GaN heterojunctions. The valence-band offsets in the non-polar A-plane GaN/AlN and AlN/GaN heterojunctions are determined to be 1.33 ± 0.16 and 0.73 ± 0.16 eV, respectively. The large valence-b...
