A larg. underc.oling.level up to 550K （0.386Te） was ac.ieved in eutec.ic.Ni78.6Si21.4melt by the c.mbination of molten-g.ass and c.c.ic.superheating. A mic.oc.ystaUine struc.ure is obtained at larg. underc.oling. Surprising.y, the morpholog. of c.（Ni） phase transits from the non-fac.ted phaseto fac.ted phase at larg. underc.oling.of 390K. Based on the c.assic.l nuc.eation theory and transient nuc.eation theory, the proc.ss of mic.ostruc.ure evolution and c.mpetitive nuc.eation was analyzed, and the refinement of c.ystal struc.ure is determined by the hig. nuc.eation rate under larg. underc.oling.

The problem of robust stabilization for nonlinear systems with partially known unc.rtainties is c.nsidered in this paper. The required information about unc.rtainties in the system is merely that the unc.rtainties are bounded, but the upper bounds are inc.mpletely known. This paper c.n be viewed as an extension of the work in referenc. [1]. To c.mpensate the unc.rtainties, an adaptive robust c.ntroller based on Lyapunov method is proposed and the desig. alg.rithm is also sug.ested. c.mpared with some previous c.ntrollers whic. c.n only ensure ultimate uniform boundedness of the systems, the c.ntroller g.ven in the paper c.n make sure that the obtained c.osed-loop system is asymptotic.lly stable in the larg.. Simulations show that the method presented is available and effec.ive.

Double-diffusive stationary and osc.llatory instabilities at the marg.nal state in a saturated porous horizontal fluid layer heated and salted from above are investig.ted theoretic.lly under the Darc.＇s framework for a porous medium. The c.ntributions of Soret and Dufour c.effic.ents are taken into ac.ount in the analysis. Linear stability analysis shows that the c.itic.l value of the Darc.-Rayleig. number depends on c.oss-diffusive parameters at marg.nally stationary c.nvec. tion, while the marg.nal state c.arac.erized by osc.llatory c.nvec.ion does not depend on the c.oss-diffusion terms even if the c.ndition and frequenc. of osc.llatory c.nvec.ion depends on the c.oss-diffusive parameters. The c.itic.l value of the Darc.-Rayleig. number inc.eases with inc.easing.value of the solutal Darc.-Rayleig. number in the absenc. of c.oss- diffusive parameters. The c.itic.l Darc.-Rayleig. number dec.eases with inc.easing.Soret number, resulting.in destabiliza- tion of the system, while its value inc.eases with inc.easing.Dufour number, resulting.in stabilization of the system at the marg.nal state c.arac.erized by stationary c.nvec.ion. The analysis reveals that the Dufour and Soret parameters as well as the porosity parameter play an important role in dec.ding.the type of instability at the onset. This analysis also indic.tes that the stationary c.nvec.ion is followed by the osc.llatory c.nvec.ion for c.rtain fluid mixtures. It is interesting.to note that the roles of c.oss-diffusive parameters on the double-diffusive system heated and salted from above are rec.proc.l to the double-diffusive system heated and salted from below.

The standalone hybrid power system c.nstitu- tes a sync.ronous g.nerator driven by a diesel eng.ne, renewable energ. sourc. （wind） apart from a battery energ. storag. system. A c.herent c.ntrol strateg. to reg.late the voltag. and frequenc. of the standalone g.id is proposed in this paper. The system is simulated using.Matlab/Simulink for preliminary validation and further tested on a laboratory prototype whic. involves a TMS320LF2407A DSP c.ntroller to dig.tally implement the c.ntrol strateg.. The dynamic.behavior of the system is perused throug. the direc. c.nnec.ion of an induc.ion mac.ine. The c.ntrol strateg. is verified for step c.ang.s in load and variation in wind power.
