biometrics-based authen.ication.system offers advan.ages of providin. high reliability an. accuracy. However the con.emporary authen.ication.system is impuissan.e to compromise. If a biometrics data is compromised, it can.ot be replaced an. ren.ered un.sable. In.this paper, a can.elable biometrics-based authen.icator is proposed to solve this irrevocability issue. The proposed approach is a two-factor authen.ication.system, which requires both of the ran.om data an. facial feature in.order to access the system. In.this system, token.zed pseudo-ran.om data is coupled with momen.based facial feature via in.er product algorithm. The output of the product is then.discretized to gen.rate a set of private bin.ry code, coin.d as 2factor-Hashin. code, which is acted as verification.key. If this biometrics-based verification.key is compromised, a n.w on. can.be issued by replacin. a differen. set of ran.om n.mber via token.replacemen.. Then. the compromised on. is ren.ered completely useless. This feature offers an.extra protection.layer again.t biometrics fabrication.sin.e the verification.code is replaceable. Experimen.al results demon.trate that the proposed system provides zero Equal Error Rate in.which there is a clear separation.in.between.the gen.in. an. the imposter distribution.population..

In.this paper we an.lyzed the effects of space an. temperature depen.en. in.emal heat gen.ration.absorption.（n.n.un.form heat source/sin.） on.magn.tohydrodyn.mic boun.ary layer flow of water based n.n.fluid over a stretchin. sheet with differen. n.n.particles. The flow is gen.rated due to lin.ar stretchin. of the sheet an. in.luen.ed by un.form magn.tic field, which is applied n.rmally to the stretchin. sheet. A scalin. group of tran.formation.is used to reduce the govern.n. momen.um an. en.rgy equation. in.o n.n.lin.ar ordin.ry differen.ial equation.. The resultin. differen.ial equation. are solved an.lytically usin. hypergeometric fun.tion. an. n.merically by the fourth order Run.e-Kutta method with shootin. techn.que. The in.luen.e of n.n.particle volume fraction. magn.tic field, Pran.tl n.mber, n.n.un.form heat source/sin., local skin.friction.coefficien. an. reduced n.sselt n.mber are in.estigated for differen. n.n.particles.

Placic horizon., defin.d as thin. wavy, harden.d layers of iron.an. organ.c matter, are rare within.the Un.ted States, occurrin. on.y in.Washin.ton. Alaska, an. Hawaii. While iron.ton. is common.in.man. soils of the southeastern.Un.ted States, it is n.t kn.wn.to con.ain.appreciable organ.c matter. As a pilot study evaluatin. the justification.for a larger study on.iron.ton. in.Louisian., a 40 m lateral exposure with suspected placic horizon. was evaluated in.Vern.n.Parish, Louisian.. Results of laboratory an.lysis show elevated levels of iron.an. organ.c matter in.the suspect horizon. that meet the criteria of placic horizon. as defin.d by the Soil Survey Staff. based on.the results of this study, addition.l evaluation.of multiple pedon. with similar features is warran.ed. Should addition.l pedon. demon.trate similar properties, a n.w great group of 'Petrudepts' would be n.eded to describe both the placic horizon. in.the pedon.an. the udic moisture regime in.which they occur.

The abstraction.of complex biological lightweight structure features in.o a producible techn.cal compon.n. is a fun.a- men.al step within.the tran.fer of design.prin.iples from n.ture to techn.cal lightweight solution.. A major obstacle for the tran.fer of n.tural lightweight structures to techn.cal solution. is their peculiar geometry. Sin.e n.tural lightweight structures possess irregularities an. often.have extremely complex forms due to elaborate growth processes, it is usually n.cessary to simplify their design.prin.iples. This step of simplification.abstraction.has been.used in.differen. biomimetic methods, but so far, it has an.arbitrary compon.n., i.e. it crucially depen.s on.the competen.e of the person.who executes the abstraction. This paper describes a n.w method for abstraction.an. specialization.of n.tural micro structures for techn.cal lightweight compo- n.n.s. The n.w method gen.rates stable lightweight design.prin.iples by usin. topology optimization.within.a design.space of preselected biological archetypes such as diatoms or radiolarian. The resultin. solution. are adapted to the techn.cal load cases an. production.processes, can.be created in.a large variety, an. may be further optimized e.g. by usin. parametric optimization.

Fe-, Y-Fe-Al- an. Y-Ce-Fe- citrates were syn.hesized in.ethylen. glycol （EG） medium un.er con.ition. similar to those used in.the polymerized complex method. Their elemen.al composition. IR,^ 13C an. ^1H n.R, X-ray photoelectron.an. Mossbauer spectra were studied, an. formulae describin. their composition.were proposed. The complexes con.ain.d EG bon.ed as adduct an. ester with citric acid ligan. an. did n.t con.ain.ligan.s with deproton.ted alcoholic groups. The complexes con.isted of agglomerated spheres, 0.7-3 μm in.diameter. The local composition.of the products was established by en.rgy dispersive X-ray microan.lysis. The comparison.of the n.mber of the ligan.s, their average electrical charge an. the esterification.degree of mon.-, di- an. trimetallic complexes proved the mixed-metal n.ture of the species studied. The thermal decomposition.of the complexes was studied an. a gen.ral scheme of the processes takin. place was proposed.

Reen.in.erin. the refractive in.ex profile of in.omogen.ous coatin.s is a troublesome task. Multiplicity of solution. may sign.fican.ly reduced by providin. addition.l in.ormation. For this reason.an.in.situ broadban. mon.torin. system was developed to measure the tran.mittan.e of the growin. film directly at the rotatin. substrate. For characterization.of these coatin.s, a n.w model was developed, which sign.fican.ly reduces the n.mber of parameters. The refractive in.ex profile may be described by a proper n.mber of equally spaced volume fraction.values usin. the bruggeman.effective media approach. A good in.tial approximation.of the refractive in.ex profile can.be gen.rated based on.deposition.rates for both materials recorded with quartz crystal mon.tor durin. man.facturin.. durin. the optimization.process, a secon. order min.mization.algorithm was used to vary the refractive in.ex profile of the whole coatin. an. film thickn.ss of the in.ermediate stages. Fin.lly, a sign.fican.ly improved accuracy of the modelled tran.mittan.e was achieved.

ductile iron.con.ain.n. 6.16wt% A1 was developed to in.estigate the effects of alumin.m on.both its microstructure an. hardn.ss. It was foun. that alumin.m n.t on.y in.reases the n.dule coun. an. pearlite con.en. but also improves the hardn.ss in.both san. mold an. metal mold castin.s. An.ealin. treatmen.s were con.ucted to attain.a homogen.us microstructure an. improve high-temperature serviceabil- ity. A ferrite/carbide or ferritic matrix was gain.d depen.in. on.the an.ealin. temperature. It is also discovered that an.ealin. has in.erse in. fluen.es on.the hardn.ss of the bulk alloy an. the ferrite phase. Although it causes a small decrease in.the bulk hardn.ss of the specimen., it leads to an.in.rease in.the microhardn.ss of the ferrite. Micro-segregation.of the alloyin. elemen.s was also in.estigated by mean. of electron.probe micro-an.lysis for the specimen. with differen. an.ealin. duration. an. the as-cast specimen.as well. An.optimum an.ealin. time was proposed to result in.the least amoun. of micro-segregation.of alumin.m an. silicon.between.graphite n.dules.
