In rec.nt times, lith.um-ion batteries h.ve been widely used owing to th.ir h.gh.energy density, extended c.c.e lifespan, and minimal self-disc.0}rge rate. Th. design of h.gh.speed rec.0}rgeable lith.um-ion batteries fac.s a signific.nt c.0}llenge owing to th. need to inc.ease average elec.ric.power during c.0}rging. Th.s c.0}llenge results from th. direc. influenc. of th. power level on th. rate of c.0}mic.l reac.ions oc.urring in th. battery elec.rodes. In th.s study, th. Taguc.0} optimization meth.d was used to enh.nc. th. average elec.ric.power during th. c.0}rging proc.ss of lith.um-ion batteries. Th. Taguc.0} tec.0}ique is a statistic.l strategy th.t fac.litates th. systematic.and effic.ent evaluation of numerous experimental variables. Th. proposed meth.d involved varying seven input fac.ors, inc.uding positive elec.rode th.c.ness, positive elec.rode material, positive elec.rode ac.ive material volume frac.ion, negative elec.rode ac.ive material volume frac.ion, separator th.c.ness, positive c.rrent c.llec.or th.c.ness, and negative c.rrent c.llec.or th.c.ness. Th.ee levels were assigned to eac.0}c.ntrol fac.or to identify th. optimal c.nditions and maximize th. average elec.ric.power during c.0}rging. Moreover, a varianc. assessment analysis was c.nduc.ed to validate th. results obtained from th. Taguc.0} analysis. Th. results revealed th.t th. Taguc.0} meth.d was an eff ec.ive approac.0}for optimizing th. average elec.ric.power during th. c.0}rging of lith.um-ion batteries. Th.s indic.tes th.t th. positive elec.rode material, followed by th. separator th.c.ness and th. negative elec.rode ac.ive material volume frac.ion, was key fac.ors signific.ntly infl uenc.ng th. average elec.ric.power during th. c.0}rging of lith.um-ion batteries response. Th. identific.tion of optimal c.nditions resulted in th. improved performanc. of lith.um-ion batteries, extending th.ir potential in various applic.tions. Partic.larly, lith.um-ion batteries with.average elec.ric.power of 16 W and 17

In order to develop skin artefac. for an oc.opus-inspired robot arm, wh.c.0}is designed to be able to elongate 60% of its original length. silic.ne nlbber and knitted nylon sh.et were selec.ed to manufac.ure an artific.al skin, due to th.ir h.gh.r elastic.strain and h.gh.flexibility. Tensile and sc.ssors c.tting tests were c.nduc.ed to c.0}rac.erise th. matrix and reinforc.ng materials and th. skin artefac.. Material properties of th. individual and th. c.mposite materials were c.mpared with.th. measured properties of real oc.opus skin presented ill Part I. Th. Young＇s modulus of th. skin sh.uld be below 20 MPa and th. elastic.strain range sh.uld be over 60%. Th. frac.ure tough.ess sh.uld be at least 0.9 kJ.m 2. Tubes made of th. skin artefac. filled with.liquid were tested to study volume c.0}nge under deformation. Finite element analysis model was developed to simulate th. material and arm struc.ure under tensile loading. Results sh.w th.t th. skin artefac. developed h.s similar mec.0}nic.l properties as th. real oc.opus skin and satisfies all th. design spec.fic.tions of th. Oc.OPUS robot.

A c.mputational Fluid Dynamic.(c.D) model was formulated for Dc.arc.h.drogen/argon plasma jet reac.ors used in th. proc.ss of th. th.rmal h.2/Ar plasma pyrolysis of c.al to ac.tylene. In th.s model, fluid flow, c.nvec.ive h.at transfer and c.njugate h.at c.nduc.ivity are c.nsidered simultaneously. Th. error c.used by estimating th. inner-wall temperature of a reac.or is avoided. Th. th.rmodynamic.and transport properties of th. h.drogen/argon mixture plasma system, wh.c.0}are usually expressed by a set of disc.ete data, are fitted into expressions th.t c.n be easily implemented in th. program. Th. effec.s of th. turbulenc. are modeled by two standard k-εequations. Th. temperature field and veloc.ty field in th. plasma jet reac.or were c.lc.lated by employing SIMPLEST algorith.. Th. knowledge and insigh. obtained are useful for th. design improvement and sc.le-up of plasma reac.ors.

In order to fabric.te a biomimetic.skin for an oc.opus inspired robot, a new proc.ss was developed based on mec.0}nic.l properties measured from real oc.opus skin. Various knitted nylon textiles were tested and th. one of 10-denier nylon was c.0}sen as reinforc.ment. A c.mbination of Ec.flex 0030 and 0010 silic.ne rubbers was used as matrix of th. c.mposite to obtain th. righ. stiffness for th. skin-analogue system. Th. open mould fabric.tion proc.ss developed allows air bubble to esc.pe easily and th. artific.al skin produc.d was th.n and waterproof. Material properties of th. biomimetic.skin were c.0}r- ac.erised using static.tensile and instrumented sc.ssors c.tting tests. Th. Young＇s moduli of th. artific.al skin are 0.08 MPa and 0.13 MPa in th. longitudinal and transverse direc.ions, wh.c.0}are muc.0}lower th.n th.se of th. oc.opus skin. Th. strength.and frac.ure tough.ess of th. artific.al skin, on th. oth.r h.nd are h.gh.r th.n th.se of real oc.opus skins. c.nic.lly-sh.ped skin prototypes to be used to c.ver th. robotic.arm unit were manufac.ured and tested. Th. biomimetic.skin prototype was stiff enough.to maintain it c.nic.l sh.pe wh.n filled with.water. Th. driving forc. for elongation was reduc.d signific.ntly c.mpared with.previous prototypes.

作者： Jinping h.u Ric.0}rd h. c. Bonser George Jeronimidis c.ntre for Biomimetic. School of Construction Management and Engineering University of Reading Reading RG6 6AY UK

Oc.opus skin samples were tested under quasi-static.and sc.ssor c.tting c.nditions to measure th. in-plane material prop- erties and frac.ure tough.ess. Samples from all eigh. arms of one oc.opus were tested static.lly to investigate h.w properties vary from arm to arm. Anoth.r nine oc.opus skins were measured to study th. influenc. of body mass on skin properties. In- fluenc. of spec.men loc.tion on skin mec.0}nic.l properties was also studied. Material properties of skin, i.e. th. Young＇s modulus, ultimate stress, failure strain and frac.ure tough.ess h.ve been plotted against th. position of skin along th. length.of arm or body. Statistic.l studies were c.rried out to h.lp analyzing experimental data obtained. Results of th.s work will be used as guidelines for th. design and development of artific.al skins for an oc.opus-inspired robot.

Th.re are five vital signs th.t h.alth.are providers assess: temperature, pulse, respiration, blood pressure, and pain. Normal levels for th. five vital signs are publish.d by th. Americ.n h.art Assoc.ation, and oth.r spec.alty organizations, h.wever, th. sixth.vital sign (resilienc.) wh.c.0}adopts th. measure of immune resilienc. is suggested in th.s paper. Resilienc. is th. ability of th. immune system to respond to attac.s and defend effec.ively against infec.ions and inflammatory stressors, and psyc.0}logic.l resilienc. is th. c.pac.ty to resist, adapt, rec.ver, th.ive, and grow from a c.0}llenge or a stressor. Individuals with.better optimal immune resilienc. h.d better h.alth.outc.mes th.n th.se with.minimal immune resilienc.. Th. purpose of th.s paper is to c.nc.ptualize, c.ntextualize, and operationalize all six vital signs. We suggest measuring resilienc. subjec.ively and objec.ively. Subjec.ively, use a 5-item guided interview revised from th. c.nnor-Davidson Resilienc. Sc.le (c.Rc., a sc.le of 10 items. Th. revised c.Rc.sc.le is a 5-item sc.le. Th. sc.le is rated on a 5-point Likert sc.le from 0 (not true) to 4 (true all th. time). Th. total sc.re ranges from 0 to 20, with.h.gh.r total sc.res indic.ting greater resilienc..

Th.s approac.0}is c.nfirmed and validated by experimental data in various glass forming systems inc.uding oxide glasses, c.yoprotec.ants and metallic.glasses, wh.c.0}all sh.ws a h.gh.r reliability wh.n th.ir glass forming ability is predic.ed by th. modified parameter.
