Th.s paper presents a study on th. statistical forecasts of typh.on tracks. Numerical models h.ve th.ir own systematic errors, like a bias. In order to improve th. accuracy of track forecasting, a statistical model called DLM (dynamic linear model) is applied to remove th. systematic error. In th. analysis of typh.ons occurring over th. western North.Pacific in 1997 and 2000, DLM is useful as an adaptive model for th. prediction of typh.on tracks.

Th. ultraviolet-B （UV-B） portion of sunligh. h.s received much.atten- tion in th. last th.ee decades, because radiation from th.s spectral region increases due to th. stratosph.ric ozone depletion, wh.ch.results from increases of ch.orofiuorocarbons in th. atmosph.re. Plant responses to UV-B exposure vary greatly and th. interpretation of and comparison between studies is h.ndered, mainly by th. contrasting experimental conditions used and interactive factors such.as low ligh. levels and possible artifacts due to th. artificial experimental conditions. It seems likely th.t increases in solar UV-B radiation of th. magnitude anticipated under current stratosph.ric ozone projections will not significantly inh.bit ph.tosynth.sis and cause DNA damage in plants. Th.s is in part due to th. wellevolved protection mech.nisms present in most plant species. One of th. significant plant responses to UV-B is ch.nges in foliar secondary ch.mistry, wh.ch.could be translated into significant effects at h.gh.r troph.c levels th.ough.plant-h.rbivore interactions and decomposition, Enh.nced UV-B radiation due to stratosph.ric ozone depletion could also cause morph.logical ch.nges th.t would affect competitive interactions, especially if contrasting UV-B sensitivity exists among th. competitors,

In th.s paper, th. problem of stability analysis for neural networks with.time-varying delays is considered. By constructing a new augmented Lyapunov-Krasovskii＇s functional and some novel analysis tech.iques, improved delaydependent criteria for ch.cking th. stability of th. neural networks are establish.d. Th. proposed criteria are presented in terms of linear matrix inequalities （LMIs） wh.ch.can be easily solved and ch.cked by various convex optimization algorith.s. Two numerical examples are included to sh.w th. superiority of our results.

Th. major flow ph.sics of th. unsteady condensation in th. subsonic flows induced by th. unsteady expansion waves in sh.ck tube was studied in th.s paper. Th. unsteady condensation ph.nomenon was analyzed by using th. two-dimensional, unsteady, Navier-Stokes equations, wh.ch.were fully coupled with.a droplet growth.equation. Th. th.rd-order TVD MUSCL sch.me was applied to solve th. governing equation systems. Th. computational results were compared with.th. previous experimental data. Th. time-dependent beh.vior of unsteady condensation of moist air in sh.ck tube was investigated in details. Th. results sh.w th.t th. major ch.racteristics of th. unsteady condensation ph.nomenon in sh.ck tube are very different from th.se in th. supersonic wind tunnels.
