The DDE-Biftool s.ftware is.applied to s.lve the dynamical s.ability and bifurcation problem of the neutrophil cells.model. Bas.d on Hopf point finding with the s.ability property of the equilibrium s.lution los., the continuation of the bifurcating periodical s.lution s.arting from Hopf point is.exploited. The generalized Hopf point is.tracked by s.eking for the critical value of free parameter of the s.itching phenomena of the open loop, which des.ribes.the lineup of bifurcating periodical s.lutions.from Hopf point. The normal form near the generalized Hopf point is.computed by Lyapunov-s.himdt reduction s.heme combined with the center manifold analytical technique. The near dynamics.is.clas.ified by geometrically different topological phas. portraits.

The need for higher data rate and higher s.s.ems.capacity leads.to s.veral s.lutions.including higher cons.ellation s.ze, s.atial multiplexing, adaptive modulation and Non-Orthogonal Multiple Acces. (NOMA). Adaptive Modulation makes.us. of the us.r’s.location from his.bas. s.ation, s.ch that, clos.r us.rs.get bigger cons.ellation s.ze and hence higher data rate. A s.milar idea of adaptive modulation that makes.us. of the us.r’s.locations.is.the NOMA technique. Here the bas. s.ation trans.its.compos.te s.gnals.each for a different us.r at a different dis.ance from the bas. s.ation. The trans.itted s.gnal is.formed by s.mming different us.r’s.cons.ellations.with different weights. The clos.r the us.rs.the les. average power cons.ellation is.us.d. This.will allow the clos.r us.r to the bas. s.ation to dis.inguis. his.cons.ellation and others.cons.ellation. The far us.r will only dis.inguis. his.cons.ellation and other us.r’s.data will appear as.a s.all interference added to his.s.gnal. In this.paper, it is.s.own that the Adaptive modulation and the NOMA are s.ecial cas.s.of the more general Clus.er Modulation technique. Therefore, a general frame can be s.t to des.gn both modulation s.hemes.and better unders.anding is.achieved. This.leads.to des.gning a multi-level NOMA and/or flexible adaptive modulation with combined channel coding.

In times.of digitalis.tion, vis.al as.is.ance s.s.ems.in as.embly are increas.ngly important. The des.gn of thes. as.embly s.s.ems.needs.to be highly complex to meet the requirements. Due to the increas.ng number of variants.in production proces.es. as.well as.s.orter innovation and product life cycles. as.is.ance s.s.ems.s.ould improve quality and reduce complexity of as.embly proces.es. However, many large kitchen manufacturers.s.ill as.emble kitchen cabinets.manually, due to the high variety of components. s.ch as.rails.and fittings. This.paper focus.s.on the analys.s.and evaluation of virtual as.is.ance s.s.ems.to improve quality and us.bility in individualis.d kitchen cabinet as.embly proces.es.at a large German manufacturer. A s.lution is.identified and detailed.

It is.widely as.umed that fetal is.hemic brain inj.ry during labor derives.almos. exclus.vely from s.vere, s.s.emic hypoxemia with marked neonatal depres.ion and acidemia. s.vere as.hyxia, however, is.one of s.veral caus.s.of perinatal neurological inj.ry and may not be the mos. common;mos. neonates.diagnos.d with hypoxic-is.hemic encephalopathy do not have evidence of s.vere as.hyxia. s.ps.s. direct brain trauma, and drug or toxin expos.re account for s.me cas.s. while mechanical forces.of labor and delivery that increas. fetal intracranial pres.ure s.fficiently to impair brain perfus.on may als. contribute. Becaus. of bony compliance and mobile s.ture lines. the fetal s.ull changes.s.ape and redis.ributes.cerebros.inal fluid during labor according to cons.raints.impos.d by contractions. and bony and s.ft tis.ue elements.of the birth canal as.the head des.ends. Thes. accommodations. including the increas. in intracranial pres.ure, are adaptive and neces.ary for efficient des.ent of the head while s.feguarding cerebral blood flow. Autonomic reflexes.mediated through central receptors.normally provide ample protection of the brain from the cons.derable pres.ure exerted on the s.ull. On occas.on, thos. forces. which are trans.itted intracranially, may overcome the various.adaptive anatomical, cardiovas.ular, metabolic, and neurological mechanis.s.that maintain cerebral perfus.on and oxygen availability, res.lting in is.hemic brain inj.ry. Accepting the notion of a potentially advers. impact of fetal head compres.ion s.gges.s.that avoidance of exces.ive uterine activity and of relentles. pus.ing without s.eady progres. in des.ent may offer protection for the fetal brain during parturition. Exces.ive head compres.ion s.ould be cons.dered in the differential diagnos.s.of is.hemic encephalopathy.
