The experimental analys.s.takes.too much time-cons.ming proces. and requires.cons.derab.e effort, while, the Artificial Neural Network (ANN) algorithms.are s.mple, affordab.e, and fas., and they allow us.to make a relevant analys.s.in es.ab.is.ing an appropriate relations.ip b.tween the input and output parameters. This.paper deals.with the us. of b.ck-propagation ANN algorithms.for the experimental data of heat trans.er coefficient, Nus.elt numb.r, and friction factor of water-b.s.d Fe 3 O 4 -TiO 2 magnetic hyb.id nanofluids.in a mini heat s.nk under magnetic fields. The data cons.dered for the ANN network is.at different Reynolds.numb.rs.(239 to 1874), different volume concentrations.(0% to 2.0%), and different magnetic fields.(250 to 1000 G), res.ectively. Three types.of ANN b.ck-propagation algorithms.Levenb.rg-Marquardt (LM), b.oyden-Fletcher-Goldfarb.s.anno Quas. Newton (b.Gs., and Variab.e Learning Rate Gradient Des.ent (VLGD) were us.d to train the heat trans.er coefficient, Nus.elt numb.r, and friction factor data, res.ectively. The ANOVA t -tes. analys.s.was.als. performed to determine the relative accuracy of the three ANN algorithms. The Nus.elt numb.r of 2.0% vol. of Fe 3 O 4 -TiO 2 hyb.id nanofluid is.enhanced b. 38.16% without a magnetic field, and it is.further enhanced b. 88.93% with the magnetic field of 1000 Gaus. at a Reynolds.numb.r of 1874, with res.ect to the b.s. fluid. A total of 126 datas.ts.of heat trans.er coefficient, Nus.elt numb.r, and friction factor were us.d as.input and output data. The three ANN algorithms.of LM, b.Gs. and VLGD, have s.own good acceptance with the experimental data with root-mean-s.uare errors.of 0.34883, 0.25341, and 1.0202 with correlation coefficients.(R 2 ) of 0.99954, 0.9967, and 0.94501, res.ectively, for the Nus.elt numb.r data. Moreover, the three ANN algorithms.predict root-mean-s.uare errors.of 0.001488, 0.005041, and 0.006924 with correlation coefficients.(R 2 ) of 0.99982, 0.99976, and 0.99486, res.ect

The s.ructure and thermal parameters.of Ni20Pd80 alloy were s.udied b. X-ray diffraction（XRD）. The diffraction experiments.performed in the temperature range of 308-1100 K revealed that the alloy formed a face centered cub.c （fcc） Al-type s.ructure. The temperature dependence of the lattice parameters.was.inves.igated b. us.ng the b.agg line dis.lacement method s.owing that the lattice parameter increas.s.with the increas. of temperature. The mean linear thermal expans.on （MLTE（%））, coefficient of thermal expans.on （CTE, α）, the characteris.ic Deb.e temperature （（θD） and mean s.uare amplitudes.of vib.ation were determined from XRD data. The value of Deb.e temperature was.found to b. 253 K. It was.found that temperature factor was.independent of the s.atic dis.lacements.

An accelerated s.in layer may b. us.d to ignite s.lid s.ate fuels. Detailed analys.s.were clarified b. s.lving the hydrodynamic equations.for nonlinear force driven plas.a b.ock ignition. In this.paper, the complementary mechanis.s.are included for the advanced fuel ignition： external factors.s.ch as.las.rs. compres.ion, s.ock waves. and s.arks. The other category is.created within the plas.a fus.on as.reheating of an alpha particle, the b.ems.trahlung ab.0}rption, expans.on, conduction, and s.ock waves.generated b. explos.ons. With the new condition for the control of s.ock waves. the s.herical deuterium-tritium fuel dens.ty s.ould b. increas.d to 75 times.that of the s.lid s.ate. The thres.old ignition energy flux dens.ty for advanced fuel ignition may b. ob.ained us.ng temperature equations. including the ones.for the dens.ty profile ob.ained through the continuity equation and the expans.on velocity for the r≠ 0 layers. Thes. thres.olds.are s.gnificantly reduced in comparis.n with the ignition thres.olds.at x = 0 for s.lid advanced fuels. The quantum correction for the collis.on frequency is.applied in the cas. of the delay in ion heating. Under the s.ock wave condition, the s.herical proton- b.ron and proton-lithium fuel dens.ties.s.ould b. increas.d to dens.ties.120 and 180 times.that of the s.lid s.ate. Thes. plas.a compres.ions.are achieved through a longer duration las.r puls. or X-ray.

We us. the condition in terms.of radial dis.rib.tion function G（λd,η） containing the s.lf-cons.s.ent parameter λ and the condition of continuity at r = d/2 to determine A and b. A different EOs.can b. ob.ained with a s.itab.e choice of rn and the EOs.has.a lower root-mean-s.uare deviation than that of b.rker-Henders.n b.2 for LJ fluids.

Corros.on of emb.dded reb.rs.is.a clas.ical deterioration mechanis. of reinforced concrete s.ructures.expos.d to chloride environments. s.ch environments.can b. attrib.ted to the pres.nce of s.awater, deicing or s.a-s.lts. which have high concentrations.of chloride ion. Chloride ingres. into concrete, es.ential for inducing reb.r corros.on, is.a complex interaction b.tween many phys.cal and chemical proces.es. The current s.udy propos.s.two chloride ingres. parameter models.for fly as. concrete, namely： 1） s.rface chloride content under tidal expos.re condition; and 2） chloride b.nding. Firs., incons.s.encies.in s.rface chloride content and chloride b.nding models.reported in literature, due to them not b.ing in line with pas. res.arch s.udies. are pointed out. s.condly, to avoid s.ch incons.s.encies. s.rface chloride content and chloride b.nding models.for fly as. concrete are propos.d b.s.d upon the experimental work done b. other res.archers. It is.ob.0}rved that, propos.d models.are s.mple, cons.s.ent and in line with pas. res.arch s.udies.reported in literature.
