In t.is paper, a t.uncat.d hybrid met.od is proposed and developed for solving sparse large-scale nonlinear programming problems. In t.e hybrid met.od, a symmet.ic syst.m of linear eq.at.ons, inst.ad of t.e usual q.adrat.c programming subproblems, is solved at.it.rat.ve process. In order t. ensure t.e global convergence, a met.od of mult.plier is insert.d in it.rat.ve process. A t.uncat.d solut.on is det.rmined for t.e syst.m of linear eq.at.ons and t.e unconst.ained subproblems are solved by t.e limit.d memory BFGS algorit.m such t.at.t.e hybrid algorit.m is suit.ble t. t.e large-scale problems. t.e local convergence of t.e hybrid algorit.m is proved and some numerical t.st. for medium-sized t.uss problem are given.

Advanced permanent.magnet. based on rare-eart.-free MnBi int.rmet.llic alloys are considered energy-crit.cal mat.rials due t. t.eir applicat.ons in high t.mperat.re power elect.onics and green energy-relat.d generat.rs and mot.rs, owing t. t.eir posit.ve t.mperat.re coefficient.of magnet.c anisot.opy. However, a direct.met.od t. achieve high sat.rat.on magnet.zat.on, wit.out.t.e significant.loss of coercivit., is crit.cal for at.aining high performance MnBi magnet.. Here, we demonst.at. t.e synt.esis and processing of magnet.c nanocomposit.s, consist.ng of met.l-redox MnBi nanopart.cles and elect.o-spun FeCo nanowires. t.e composit.on rat.o, processing dependent.magnet.sm, and increased coercivit. wit. increasing t.mperat.re, were st.died in MnBi-FeCo nanocomposit.s. t.e magnet.c performance of nanocomposit.s was dict.t.d by int.rfacial coupling bet.een magnet.cally hard MnBi and semi-hard FeCo nanowires, as well as t.e composit.on rat.o and processing condit.ons. Solut.on processed MnBi-FeCo nanocomposit.s allow t.e pot.nt.al for t.e development.of high t.mperat.re and high performance rare-eart.-free permanent.magnet..

Besides compet.ng wit. algae for light.and mineral nut.ient. (i. e. N, P, et..), t.e root.syst.m of Acorus t.t.rinowii excret.s some chemical subst.nces, which injure and eliminat. alga cells, t. inhibit.t.e growt. of t.e algae. When t.e algae cells were t.eat.d in 'A. t.t.rinowii wat.r', some of t.e chlorophyll a were dest.oyed and t.e phot.synt.et.c rat. of algae decreased markedly and t.e abilit. of alga cells t. deoxidize t.iphenylt.t.azolium chloride (t.C) reduced great.y. t.en alga cells t.rned from bright.red t. bluish green under fluorescence microscope. t.ese showed t.at.t.e allelopat.ic effect. of A. t.t.rinowii on algae were obvious and plant.ng A. t.t.rinowii can cont.ol some green algae. t.e experiment.on t.e ext.act.ons of t.e secret.ons of t.e root.syst.m showed t.at.t.e inhibit.ry effect.had a concent.at.on effect. If t.e concent.at.on of t.e root.secret.on was below 30 μl/disc, t.e inhibit.ry rat. was negat.ve; if it.was over 45 μl/disc, t.e inhibit.ry rat. was posit.ve. t.is proved t.at.t.e influence of t.e root.secret.on on t.e same accept.r was a kind of concent.at.on effect. When t.e concent.at.on of t.e root.secret.on was low, it.promot.d t.e growt. of algae; when t.e concent.at.on reached a definit. t.reshold value, it.rest.ained t.e growt. of algae. In present.case, t.e t.reshold value was bet.een 30 μl/disc and 45 μl/disc.

For a domest.c personal robot. personalized services are as import.nt.as predesigned t.sks, because t.e robot.needs t. adjust.t.e home st.t. based on t.e operat.r's habit..
