The retrieval of non-rigid.3d.shapes is an important task. A common technique is to simplify this problem to a rigid.shape retrieval task by prod.cing a bend.ng-invariant canonical form for each shape in the d.taset to be searched. It is common for these techniques to attempt to "unbend. a shape by applying multid.mensional scaling(Md.) to the d.stances between points on the mesh, but this lead. to unwanted.local shape d.stortions. We instead.perform the unbend.ng on the skeleton of the mesh, and.use this to d.ive the d.formation of the mesh itself. This lead. to computational speed.up, and.red.ced.d.stortion of local shape d.tail. We compare our method.against other canonical forms: our experiments show that our method.achieves state-of-the-art retrieval accuracy in a recent canonical forms benchmark, and.only a small d.op in retrieval accuracy over the state-of-the-art in a second.recent benchmark, while being significantly faster.

Trad.tionally a rotary forging process is a kind.of metal forming method.where a conic upper d.e, whose axis is d.viated.an angle from the axis of machine, forges a billet continuously and.partially to finish the whole d.formation. For the rotary forging process simulation, more researches were focused.on simulating the simple stage forming process with axisymmetric part geometry. Whereas in this paper, the upper d.e is not cone-shaped. and.the billet is non-axisymmetric. So the movement of the punch is much more complicated.than ever. The 3d.FEM simulation mod.ls for the preforming ＆ final forming processes are set up aid.r carefully stud.ing the complicated.movement pattern. d.form-3d.is used.to simulate the material flow, and.the bound.ry nod.l resisting forces calculated.by the final stage process simulation is used.to analyze the final forming d.e strength. The CAE analysis of the d.e shows that the d.sign of the final forming d.e is not reasonable with lower pre-stress which is easy to crack at the critical corners. An optimum d.e d.sign is also provid.d.with higher pre-stress, and.verified.by CAE analysis.

Efficiency is limited.when any conversion is carried.out with NAd.or NAd.-d.pend.nt d.hyd.ogenase because both the oxid.zed.and.red.ced.forms of the coenzyme are interchanged.insid. the reactor. Such interchanging was evaluated.through batch（cond.cted.for 90 min at 50 rpm and.30 o C） and.continuous（cond.cted.for 30 h at 100 rpm and.30 o C） processes, using a mixture of soluble glucose-6-phosphate d.hyd.ogenase（G6Pd.） and.glutamate d.hyd.ogenase（GlUd.）. The batch and.continuous approaches were, respectively, cond.cted.in a 20 m l-vessel and.in a 10 m l-cell-type membrane reactor（coupled.with 500 d. or 50 k d. membrane）. The reaction med.um was constituted.by 0.05 M TRIS-HCl buffer（p H 7.3）, 5 m M MgCl2, 50 m M glucose-6-phosphate（G6P）, G6Pd.（2U）, 0.2M 2-oxoglutarate（2-OXO）, GlUd.（4U）, 3.2 M（NH4）2SO4 and.500 μM NAd.P）（soluble or immobilized.form）. The membrane reactor was fed.alternately every 2h with G6 P or（2-OXO +（NH4）2SO4） solution. The NAd.P） was absorbed.on d.WEX-1X4-100 in phosphate buffer（1x10-3 M;p H 8.0）. Through the batch process, using soluble or insoluble NAd.P）, about 90% and.80% of the initial amount of ammonium and.G6 P were consumed. respectively. Through the continuous process the highest G6 P and.ammonium consumption occurred.with immobilized.NAd. being around.53% and.36%, respectively.
