We develop a hybrid type of quantum annealing in which we control temperature and quantum field simultaneously. We study the efficiency of proposed quantum annealing and find a good schedule of changing thermal fluctuation and quantum fluctuation. In this paper, we focus on clustering problems which are important topics in information science and engineering. We obtain the better solution of th...

We report on the demonstration of the effectiveness of nanosecond laser annealing on optical properties of phosphorus ion (P)-implanted ZnO nanorods (NRs). Vertically-alligned ZnO NRs have been synthesized by nanoparticle-assisted pulsed laser deposition (NAPLD) on c-plane sapphire substrates. The pre-laser annealing was performed with the third harmonic (355 nm) of a Qwitched Nd:YAG laser at a...

FePt nanoparticles with thermally stable room-temperature ferromagnetism are investigated. The monodisperse nanoparticles are prepared by chemical synthesis and a salt-matrix annealing technique. Structural and magnetic characterizations confirm the phase transition from the disordered face-centered cubic structure. In this paper, 3 nm FePt nanoparticles are first synthesized by superhydride re...

Zinc Sulfide (ZnS) thin films were deposited on glass substrates at the pressure of 10-6 mbar by thermal resistor evaporation technique. The effects of annealing on the structural, optical properties of ZnS films were studied. Crystalline ZnS films have been analyzed by X-ray diffraction. Only cubic phase with the preferred (111) plane was found in ZnS films. Optical characteristics were studie...

Calcium fluoride nanoparticles with special amount of cerium ion (%1) were synthesized by coprecipitation. Fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), absorption and photoluminescence (PL) from CaF2Ce nanoparticles has been investigated. FTIR spectra reveal that there are some amounts of OH, NO3 and other organic functional groups on the parti...

Simulated annealing is a well-studied local search metaheuristic used to address discrete and, to a lesser extent, continuous optimization problems. The key feature of simulated annealing is that it provides a mechanism to escape local optima by allowing hill-climbing moves (i.e., moves which worsen the objective function value) in hopes of finding a global optimum. A brief history of simulated...

Multilayers of Ni-2lAl and Ni-ZOCr-1OAl were subjected to ion beam mixing using 350 keV Ni+ ions and/or thermal annealing at 440 o C to study the development of grain growth and phase morphology. Two film thicknesses of Ni-21 Al (60 and 120 nm) were investigated. Both thermal annealing and irradiation resulted in grain growth in the Ni-21Al samples. Grain size increased by a factor of 7 after i...

thermoluminescent detector/LiF:Mg,Ti/glow curve deconvolution/annealing/NIRS-HIMAC The stability of glow peaks in LiF:Mg,Ti (TLD-600) exposed to a high-energy Fe-ion beam was examined in comparison to Cs γ -ray irradiation under changing annealing conditions. The peak areas induced by the Fe ions were much smaller than those by γ -rays. The sizes and positions of peaks 3–5 in Fe-ion irradiated ...

Mean field annealing(MFA) is a promising tool in optimization and a neural network model based on the graph matching have attracted attention due to a number of benefits over conventional recognition models. We present a neural network model for hand-written digits recognition using graph matching and two annealing techniques, MFA and one-variable stochastic simulated annealing(OSSA). OSSA make...
