In this research, PbFe11Co1O19 with annealing temperatures of 600, 700, 750, 800, 850 and 900 ˚C at annealing time of 3 h were synthesized by sol-gel method. The structural, microstructure properties and morphology of the samples have been studied by XRD, FT-IR and FESEM. Also, magnetic and dielectric properties of samples were characterized by VSM and LCR meter. The results of measurements of ...

We investigated one-step, rapidly cleaning, and annealing thin wire copper using plasma generated by Dielectric-Barrier Discharge (DBD) at atmospheric pressure in a coaxial cylindrical reactor. The thin copper wire cleaning and annealing processes strongly depend on the input power, the dimensions of the reactor, and the annealing duration. The minimum input power was calculated under stable an...

Abnormal behavior of dopant activation was observed in P + /B + ion shower doped poly-Si upon post implant annealing. Phosphorous or boron was implanted by ion shower doping using a source gas mixture of PH3/H2 or B2H6/H2. Activation annealing was conducted using a tube furnace in the temperature ranges from 350 o C to 650 o C. Hall measurement revealed that reverse annealing occurred for poly-...

zno thin films were deposited on si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°c). dependence of the crystallographic structure, nano-strain, chemical composition and surface physical morphology of these layers on annealing temperature were studied. the crystallographic structure of films was studied using x-ray diffracti...

An algorithm is developed to statistically find the best global fit of a nonlinear non-convex cost-function over a D-dimensional space. It is argued that this algorithm permits an annealing schedule for ''temperature'' T decreasing exponentially in annealing-time k, T = T 0 exp(−ck 1/D). The introduction of re-annealing also permits adaptation to changing sensitivities in the multi-dimensional ...

Since the logistics is an industry with relatively higher energy consumption, the building industry lowcarbon logistics ought to attract wide attentions from the building enterprises. Simulated annealing is an effective intelligent algorithm for optimizing the building materials logistics route. This paper analyzes the similarities between the process of the building materials logistics route o...

Virtually all implementations of simulated annealing are simplified by assuming discrete unknowns, however continuous-parameter annealing has many potential applications to image processing. Widely-scattered problems such as formant tracking, boundary estimation and phaseunwrapping can all be approached as the annealed minimizations of continuous B-spline parameters. The benefits of simulated a...

DNA double-strand breaks (DSBs) pose a serious threat to genomic integrity. If unrepaired, they can lead to chromosome fragmentation and cell death. If repaired incorrectly, they can cause mutations and chromosome rearrangements. DSBs are repaired using end-joining or homology-directed repair strategies, with the predominant form of homology-directed repair being synthesis-dependent strand anne...

Torsion giant impedance ~TGI! ratio, (DZ/Z)j , has been measured in as-cast and annealed ~Co0.94Fe0.06)72.5B15Si12.5 amorphous wire. Two-step current annealing has been employed: pre-annealing ~550 mA, 2 min! plus current annealing under torsion stress ~33 p rad/m, 450 mA, up to tann5105 min!. Pre-annealing results in a drastic increase of (DZ/Z)j ~from 155% to 260%! and decrease of the asymmet...

Relations of simulated annealing and quantum annealing are studied by a mapping from the transition matrix of classical Markovian dynamics of the Ising model to a quantum Hamiltonian and vice versa. It is shown that these two operators, the transition matrix and the Hamiltonian, share the eigenvalue spectrum. Thus, if simulated annealing with slow temperature change does not encounter a difficu...
