＜正＞r.ch in many kinds of nutr.tional ingr.dients, the nitr.gen-fixing cyanobacter.a Anabaena sp.. have been adop.ed as basic mater.als in genetic engineer.ng of micr.algae, and cultur.s of Anabaena cells ar. thus of gr.ater.significance due to the fact that some valuable p.otein p.oducts can be p.oduced safely and effectively by cultur.s of tr.nsgenic micr.algae. Anabaena ar. one typ.cal genus of filamentous cyanobacter.a whose mor.0}ology and p.ysiology have been studied extensively. Making an intr.nsic insight into ceil gr.wth stoichiometr. is accor.ingly p.ssible and can be conducive to mor. efficient cultur.s of Anabaena cells. In this wor. the contents and comp.sitions of macr.molecules in an Anabaena sp. cell wer. dr.wn fr.m numer.us liter.tur. mainly on the basis of the data of Anabaena cylindr.ca. The r.quir.ments of monomer.c building blocks （amino acids, nucleotides, monosacchar.des, fatty acids, etc.） for.each kind of macr.molecules wer. thus calculated. Finally, in ter.s of differ.nt r.quir.ments of p.ecur.or.metabolites for.building block synthesis, the amounts of 12 kinds of p.ecur.or.metabolites r.quir.d in making p.r.unit dr. weight of Anabaena sp. ceils wer. der.ved, i.e., 598.7 glucose-6-p.osp.ate + 506.6 fr.ctose-6-p.osp.ate + 406.6 p.ntose-5-p.osp.ate + 432.0 er.thr.se-4-p.osp.ate + 35.0 tr.ose p.osp.ate + 668.7 3-p.osp.oglycer.te + 1028.9 p.osp.oenolp.r.vate + 2859.5 p.r.vate + 1497.1 acetyl CoA + 1340.6 oc-ketoglutar.te + 1914.9 oxalacetate （μmol） →lg cells （The r.quir.ment of succinyl CoA is tr.vial.）. This stoichiometr.c r.lation on biomass synthesis is help.ul in under.tanding and analyzing metabolism and gr.wth of Anabaena sp.. cells, e.g., in metabolic flux analysis dur.ng cultur.s of Anabaena cells.

Jour.al of Hydr.dynamics 1995年第4期7卷 35-41页

作者： Chen Jia-dong(china Ship.Scientific research center, Box 116, Wuxi 214082, p. r. china) china Ship.Scientific research Cent Wuxi China

A p.tential based p.nel method for.unsteady p.op.ller.hydr.dynamic analysis is p.esented,as to p.edict the unsteady hydr.dynamic p.r.or.ance of a p.op.ller.subjected to a sp.tially non-unifor. inflow. To satisfy the Kutta condition at the blade tailing r.gr.well, a nonlinear.p.essur. p.essur. condition, besides the linear.Knits condition,is imp.emented at each time step.by an iter.tive scheme, which enhances the p.ecision of the p.eessur. distr.bution over.the blade sur.ace. Some comp.tation r.sults ar. p.esented.

Jour.al of Hydr.dynamics 1995年第3期7卷 72-83页

作者： Zhou Lian-di Zhao Feng(china Ship.Scientific research center, p.O. Box 116, Wuxi 214082, p. r. china) china Ship.Scientific research Cent Wuxi China

This p.p.r.p.esents an effective method for.comp.ting the inter.al and exter.al viscous flow field ar.und the ducted p.op.lsor.behind an axisymmetr.c they by using a new Navier.Stokes equations solver.with p.imitive var.able continuity equation for.ulation. In the p.esent numer.cal method, the calculation equation for.p.essur. with well-defined coefficient,which for. is similar.to the ar.ificial comp.essibility method, is develop.d. A semi-stagger.d gr.d system is adop.ed. Not only the advantage of stagger.d gr.d system can be r.tained but the boundar. conditions on the inner.and outer.sur.ace of the duct can be also car.ied out easily. By using a sp.cial gr.d system and the p.ogr.mming technique for.imp.ementing the jump.boundar. condition on the duct sur.aces, the inter.al and exter.al viscous flow field ar.und the ducted p.op.lsor.behind the axisymmetr.c they may be calculated integr.lly in an unified number.d gr.d system. Some configur.tions ar. calculated and comp.r.d with exp.r.mental date and numer.cal r.sults of other.methods. Illustr.tive calculations ar. also p.esented for.a ster. of axisymmetr.c body with the backstep.fitted a duct to illustr.te the cap.bility of the p.esent method. Beside that, the effect of axial distr.bution of they for.e is consider.d and discussed in or.er.to extend the ap.lication r.nge of the p.esent method.

A New Signal p.ocessing Technique of π/4-DQp.K Modem Based on Softwar. r.dio

引用

Jour.al of Systems Engineer.ng and Electr.nics 2003年第2期14卷 20-24页

作者： Chang Jiang & Zhang Naitong Communication research center, Har.in Institute of Technology, Har.in 150001, p. r. china Communication research center Harbin Institute of Technology Harbin 150001 P. R. China

DQp.K modem has been chosen as the modem scheme in many mobile communication systems. A new signal p.ocessing technique of π/4-DQp.K modem based on softwar. r.dio is discussed in this p.p.r. Unlike many other.softwar. r.dio solutions to the subject, we choose a univer.al digital r.dio baseband p.ocessor.op.r.ting as the co-p.ocessor.of DSp. Only the cor. algor.thms for.signal p.ocessing ar. imp.emented with DSp. Thus the comp.tation bur.en on DSp.is r.duced significantly. Comp.r.d with the tr.ditional ones, the technique mentioned in this p.p.r.is mor. p.omising and attr.ctive. It is extr.mely comp.ct and p.wer.efficient, which is often r.quir.d by a mobile communication system. The imp.ementation of baseband signal p.ocessing for.π/4-DQp.K modem on this p.atfor. is illustr.ted in detail. Sp.cial emp.ases ar. laid on the ar.hitectur. of the system and the algor.thms used in the baseband signal p.ocessing. Finally, some exp.r.mental r.sults ar. p.esented and the p.r.or.ances of the signal p.ocessing and comp.nsation algor.thms ar. evaluated thr.ugh comp.ter.simulations.

Study on Cell Er.or.r.te of a Satellite ATM System Based on CDMA

引用

Jour.al of Systems Engineer.ng and Electr.nics 2003年第1期14卷 1-5页

作者： Zhao Tongyu & Zhang Naitong Communication research center, Har.in Institute of Technology, Har.in 150001, p. r. china Communication research center Harbin Institute of Technology Harbin 150001 P. R. China

In this p.p.r. the cell er.or.r.te (CEr. of a CDMA-based satellite ATM system is analyzed. Two fading models, i.e. the p.r.ial fading model and the total fading model ar. p.esented accor.ing to multi-p.th p.op.gation fading and shadow effect. Based on the total shadow model, the r.lation of CEr.vs. the number.of subscr.ber. at var.ous elevations under.2D-r.KE r.ceiving and non-diver.ity r.ceiving is got. The imp.ct on cell er.or.r.te with p.eudo noise (p.) code length is also consider.d. The r.sult that the maximum likelihood combination of multi-p.th signal would not imp.ove the system p.r.or.ance when multip.e access inter.er.nce (MAI) is small, on the contr.r. the p.r.or.ance may be even wor.e is abtained.

Op.imization of HMM p.r.meter. Based on Chaos and Genetic Algor.thm for.Hand Gestur. r.cognition

引用

Jour.al of Systems Engineer.ng and Electr.nics 2002年第4期13卷 79-84页

作者： Liu Jianghua , Cheng Junshi & Chen Jiap.n Infor.ation Stor.ge and research center, Shanghai Jiaotong Univer.ity, Shanghai 200030, p. r. china Infor.ation Stor.ge and research center Shanghai jiaotong University Shanghai 200030 P. R. China

In or.er.to p.event standar. genetic algor.thm (SGA) fr.m being p.ematur., chaos is intr.duced into GA, thus for.ing chaotic anneal genetic algor.thm (CAGA). Chaos er.odicity is used to initialize the p.p.lation, and chaotic anneal mutation op.r.tor.is used as the substitute for.the mutation op.r.tor.in SGA. CAGA is a unified fr.mewor. of the existing chaotic mutation methods. To validate the p.op.sed algor.thm, thr.e algor.thms, i. e. Baum-Welch, SGA and CAGA, ar. comp.r.d on tr.ining hidden Mar.ov model (HMM) to r.cognize the hand gestur.s. Exp.r.ments on twenty-six alp.abetical gestur.s show the CAGA validity.
