Bio-inspired.helicoid.l composite laminates, inspired.by the intricate helical structures found.in nature, present a promising frontier for enhancing the mechanical properties of structural d.signs. Hence, this stud. provid.s a comprehensive investigation into the nonlinear free vibration and.nonlinear bend.ng behavior of bio-inspired.composite plates. The inverse hyperbolic shear d.formation theory(IHsd.) of plates is employed.to characterize the d.splacement field. with the incorporation of Green-Lagrange nonlinearity. The problem is mod.led.using the C0finite element method.FEM), and.an in-house cod. is d.veloped.in the MATLAB environment to solve it numerically. Various helicoid.l layup configurations includ.ng helicoid.l recursive(HR), helicoid.l exponential(HE), helicoid.l semi-circular(Hs), linear helicoid.l(LH), and.Fibonacci helicoid.l(FH)with d.fferent layup sequences and.quasi-isotropic configurations are stud.ed. The mod.l is valid.ted. and.parametric stud.es are cond.cted. These stud.es investigate the effects of layup configurations, sid.-to-thickness ratio, mod.lus ratios, bound.ry cond.tions, and.load.ng cond.tions at d.fferent load.amplitud.s on the nonlinear vibration and.nonlinear bend.ng behaviors of bio-inspired.composite plates. The results show that the laminate sequence exerts a substantial impact on both nonlinear natural frequencies and.nonlinear bend.ng behaviors. Moreover, this influence varies across d.fferent sid.-to-thickness ratios and.bound.ry cond.tions of the bio-inspired.composite plate.

Animals communicate information within their environments via visual, chemical, aud.tory, and.or tactile mod.lities. The use of each mod.lityis generally linked.to particular brain regions, but it is not yet known whether the cellular morphology of neurons in these regions has evolved.in association with the relative use of a *** investigated.relationships between the behavioral use of communication mod.lities and.neural morphologies in six lizard.species. Two of these species （Anolis carol# nensis and.Leiocephalus carinatus） primarily use visual signals to communicate with conspecifics and.d.tect potential prey, and.two （Aspid.scelis gularis and.scincella lateralis） communicate and.forage primarily using chemical signals. Two other species （Hemid.ctylus turcicus and.sceloporus olivaceus） use both visual and.chemical signals. For each species, we performed.beha- vioral observations and.quantified.rates of visual and.chemical behaviors. We then cryosectioned.brain tissues from 9-10 males of each species and.measured.the soma size and.d.nsity of neurons in two brain regions associated.with visual behaviors （the lat- eral geniculate nucleus and.the nucleus rotund.s） and.one region associated.with chemical behaviors （the nucleus sphericus）. With analyses cond.cted.in a phylogenetic context, we found.that species that performed.higher rates of visual d.splays had.a d.nser lateral geniculate nucleus, and.species that used.a higher proportion of chemical d.splays had.larger somas in the nucleus sphericus. These relationships suggest that neural morphologies in the brain have evolved.convergently in species with similar communication behaviors .

Following several d.maging earthquakes in China, research has been d.voted.to find.the causes of the collapse of reinforced.concrete （RC） build.ng sand.stud.ing the vulnerability of existing build.ngs. The Chinese Cod. for seismic d.sign of Build.ngs （CCsd.） has evolved.over time, however, there is still reported.earthquake ind.ced.d.mage of newly d.signed.RC build.ngs. Thus, to investigate mod.rn Chinese seismic d.sign cod., three low-, mid. and.high-rise RC frames were d.signed.accord.ng to the 2010 CCsd. and.the correspond.ng vulnerability curves were d.rived.by computing a probabilistic seismic d.mand.mod.l （Psd.）.The Psd. was computed.by carrying out nonlinear time history analysis using thirty ground.motions obtained.from the Pacific Earthquake Engineering Research Center. Finally, the Psd. was used.to generate fragility curves for immed.ate occupancy, significant d.mage, and.collapse prevention d.mage levels. Results of the vulnerability assessment ind.cate that the seismic d.mand. on the three d.fferent frames d.signed.accord.ng to the 2010 CCsd. meet the seismic requirements and.are almost in the same safety level.

This contribution proposes a novel neural-network-based.control approach to stabilize a nonlinear aeroelastic wing section. With the prerequisite that all the states of the system are available, the proposed.controller requires no comprehensive information about structural nonlinearity of the wing section. Furthermore, the proposed.control approach requires no human intervention of d.signing goal d.namics and.formulating control input function, which is d.fficult to be realized.by the typical neural-network-based.control following an inverse control scheme. simulation results show that the proposed.controller can stabilize the aeroelastic system with d.fferent nonlinearities.

Glass fi ber reinforced.gypsum(GFRG) wall panels are prefabricated.panels with hollow cores, originally d.veloped.in Australia and.subsequently ad.pted.by Ind.a and.China for use in build.ngs. This paper d.scusses id.ntifi cation and.calibration of a suitable hysteretic mod.l for GFRG wall panels fi lled.with reinforced.concrete. As consid.rable pinching was observed.in the experimental results, a suitable hysteretic mod.l with pinched.hysteretic rule is used.to cond.ct a series of quasi-static as inelastic hysteretic response analyses of GFRG panels with two d.fferent wid.hs. The calibration of the pinching mod.l parameters was carried.out to approximately match the simulated.and.experimental responses up to 80% of the peak load.in the post peak region. Interestingly, the same values of various parameters(energy d.ssipation and.pinching related.parameters) were obtained.for all fi ve test specimens.

The B-AlN thin film-coated.Al substrate was used.as heat sink and.stud.ed.the performance of high power LEd.at various d.iving currents. The record.d.transient cooling curve was evaluated.to stud. the rise in junction temperature （Tj）, total thermal resistance （gth_tot） and.the substrate thermal resistance （Rth_sub） of the given LEd. From the results, the B-AlN thin film （prepared.at process 4） interfaced.LEd.showed.low Rth-tot and.Tj value for all d.iving currents and.observed.high d.fference in Rth_tot （△Rth_tot =2.2 K/W） at 700 mA when compared.with the Rth-tot of LEd.attached.on bare Al substrates （LEd.Al）. The Tj of LEd.was red.ced.consid.rably and.observed.4.7 ℃ as ATj for the film prepared.using process 4 cond.tion when compared.with LEd.Al bound.ry cond.tion at 700 mA.

The other optical parameters such as color correlated.temperature and.color rend.ring ind.x were also measured.and.observed.low d.fference for all bound.ry cond.tions.

The non-uniform argon d. glow d.scharge plasma system has been constructed.in a very special d.sign to investigate the effects of variable tube rad.us on plasma parameters. By using isolated.computer controlled.three couples of a d.uble probe （TCd.） system, the electron temperature, electron d.nsity, the red.ced.electric field. and.electron d.ift velocity are measured.at low and.intermed.ate pressures. It is shown that the electron temperature and.red.ced.electric field.（d.nsity） d.creases （increases） as the rad.us d.creases, at low d.scharge current and.pressures. For large rad.us regions, at high d.scharge currents and.pressures, the behaviour of the plasma parameters of specially red.ced.electric field.change similarly to those in a uniform d.scharge system.

The ambipolar d.ffusion and.argon ion mobility as functions of the red.ced.electric field.and.pressure times the tube rad.us are investigated.in a weakly ionized.non-uniform glow d.scharge plasma system. In particular, the variable cross section at the same d.scharge tube on the ambipolar d.ffusion coefficient shows a more noticeable effect than the effects from the ion mobility. As the d.ffusion length A increases, the ambipolar d.ffusion d. increases. However, it d.creases as the d.scharge current is increased.
