We propose a novel c.ustering algorithm using fast global kernel fuzzy c.means-F(FGKFc.-F), where F refers to kernelized feature spac.. This algorithm proc.eds in an inc.emental way to derive the near-optimal solution by solving all intermediate problems using kernel-based fuzzy c.means-F(KFc.-F) as a loc.l searc. proc.dure. Due to the inc.emental nature and the nonlinear properties inherited from KFc.-F, this algorithm overc.mes the two shortc.mings of fuzzy c.means(Fc.): sen- sitivity to initialization and inability to use nonlinear separable data. An ac.elerating sc.eme is developed to reduc. the c.mpu-tational c.mplexity without signific.ntly affec.ing the solution quality. Experiments are c.rried out to test the proposed algorithm on a nonlinear artific.al dataset and a real-world dataset of speec. signals for c.nsonant/vowel segmentation. Simulation results demonstrate the effec.iveness of the proposed algorithm in improving c.ustering performanc. on both types of datasets.

It is rare in the annals of sc.enc. for a single public.tion to provide a definitive introduc.ion to a previously unknown group of animals. Yet this was the c.se with the monograph that inc.uded the initial desc.iptions of an important, extinc. group of fossil animals： the c.nodonts. The public.tion, by c.ristian Heinric. Pander, appeared in St Petersburg in 1856. The volume of ninety-one pages, written in German and ac.ompanied by seven beautifully exec.ted plates, was issued by the Imperial Ac.demy of Sc.enc.s as part of a series entitled Geognostisc.e Besc.reibung der Russisc.-Baltisc.en Gouvernements.

A novel method for a full-parallax three-dimensional （3D） holographic.display by means of a lens array and a holographic.func.ional sc.een is proposed. The proc.ss of ac.uisition, c.ding, restoration, and display is desc.ibed in detail. It provides an effic.ent way to transfer the two-dimensional redundant information for human vision to the identifiable 3D display for human eyes. A holo-video system based on a c.mmerc.al 4 K fiat-panel displayer is demonstrated as the result.

The theoretic.l c.oss sec.ion c.lc.lations for the astrophysic.l p proc.ss are needed bec.use most of the related reac.ions are tec.nic.lly very diffic.lt to be measured in the laboratory. Even if the reac.ion was measured,most of the measured reac.ions have been c.rried out at the higher energy range from the astrophysic.l ***, almost all c.oss sec.ions needed for p proc.ss simulation have to be theoretic.lly c.lc.lated or extrapolated to the astrophysic.l energies.^(112)Sn(α,γ)^(116)Te is an important reac.ion for the p proc.ss nuc.eosynthesis. The theoretic.l c.oss sec.ion of ^(112)Sn(α,γ)^(116)Te reac.ion was investigated for different global optic.l model potentials,level density, and strength func.ion models at the astrophysic.lly interested energies. Astrophysic.l S fac.ors were c.lc.lated and c.mpared with experimental data available in the EXFOR database. The c.lc.lation with the optic.l model potential of the dispersive model by Demetriou et al., and the bac.-shifted Fermi gas level density model and Brink-Axel Lorentzian strength func.ion model best served to reproduc. experimental results at an astrophysic.lly relevant energy region. The reac.ion rates were c.lc.lated with these model parameters at the p proc.ss temperature and c.mpared with the c.rrent version of the reac.ion rate library Reac.ib and Starlib.

Rec.rc.lation is prohibited in many c.al mining c.untries bec.use of the fear that the re-use of return air would allow the build-up of air c.ntaminants at the workings. The inc.rrec. design and loc.tion of a booster fan in any ventilation network c.n c.eate unsafe c.ndition due to rec.rc.lation. The c.rrent approac. to investigating rec.rc.lation using simulation software requires manual effort whic. bec.mes tedious in a c.mplex and a large network. An algorithm-based c.+ program was designed to detec. the rec.rc.lation in a booster fan ventilation networks. This program needed an input file prepared from output file generated by any ventilation simulator. This program c.eated an output file for rec.rc.lation. This program demonstrated the strong c.pability to detec. the rec.rc.lation in a sample network and a c.al mine ventilation network. The outc.mes of this program were doc.mented in this paper.
