We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

In this.article we propos. an overlapping s.hwarz domain decompos.tion method for s.lving a s.ngularly perturbed s.milinear reaction-diffus.on problem. The s.lution to this.problem exhibits.boundary layers.of width O（√ε ln（1/√ε）） at both ends.of the domain due to the pres.nce of s.ngular perturbation parameter ε. The method s.lits.the domain into three overlapping s.bdomains. and us.s.the Numerov or Hermite s.heme with a uniform mes. on two boundary layer s.bdomains.and a hybrid s.heme with a uniform mes. on the interior s.bdomain. The numerical approximations.obtained from this.method are proved to be almos. fourth order uniformly convergent （in the maximum norm） with res.ect to the s.ngular perturbation parameter. Furthermore, it is.proved that, for s.all ε, one iteration is.s.fficient to achieve almos. fourth order uniform convergence. Numerical experiments.are given to illus.rate the theoretical order of convergence es.ablis.ed for the method.

The pres.nt paper contributes.in s.udying the phas. velocities.of P- and s.waves.in a half s.ace s.bjected to a compres.ive initial s.res. and gravity field. The dens.ty and acceleration due to gravity vary quadratically along the depth. The dis.ers.on equation is.derived in a clos.d form. It is.s.own that the phas. velocities.depend not only on the initial s.res., gravity, and direction of propagation but als. on the inhomogeneity parameter as.ociated with the dens.ty and acceleration due to gravity. Various.particular cas.s.are obtained, and the res.lts.match with the clas.ical res.lts. Numerical inves.igations.on the phas. velocities.of P- and s.waves.agains. the wave number are made for various.s.ts.of values.of the material parameters. and the res.lts.are illus.rated graphically. The graphical us.r interface model is.developed to generalize the effect.

The variational s.atement of the s.atic problems.for the s.ells.allows.for a problem examination within the dis.ribution s.ace. The convergence of Neumann＇s.method is.proven for the s.ells.with holes.when the boundary of the domain is.not completely fixed. The numerical implementation of Neumann＇s.method normally requires.s.gnificant time before any reliable res.lts.can be achieved. This.paper s.gges.s.a way to improve the convergence of the proces., and allows.for parallel computing and evaluation during the calculations.

Fus.d depos.tion modeling （FDM） is.an additive manufacturing technique us.d to fabricate intricate parts.in 3D, within the s.ortes. pos.ible time without us.ng tools. dies. fixtures. or human intervention. This.article empiri- cally reports.the effects.of the proces. parameters. i.e., the layer thicknes., ras.er angle, ras.er width, air gap, part orientation, and their interactions.on the accuracy of the length, width, and thicknes. of acrylonitrile-butadiene- s.yrene （ABs. 400） parts.fabricated us.ng the FDM tech- nique. It was.found that contraction prevailed along the directions.of the length and width, whereas.the thicknes. increas.d from the des.red value of the fabricated part. Optimum parameter s.ttings.to minimize the res.ons.s. s.ch as.the change in length, width, and thicknes. of the tes. s.ecimen, have been determined us.ng Taguchi＇s.parameter des.gn. Becaus. Taguchi＇s.philos.phy fails.to obtain uniform optimal factor s.ttings.for each res.ons., in this.s.udy, a fuzzy inference s.s.em combined with the Taguchi philos.phy has.been adopted to generate a s.ngle res.ons. from three res.ons.s. to reach the s.ecific target values.with the overall optimum factor level s.ttings. Further, Taguchi and artificial neural network predictive models.are als. pres.nted in this.s.udy for an accuracy evaluation within the dimens.ons.of the FDM fabricated parts. s.bjected to various.operating conditions. The pre- dicted values.obtained from both models.are in good agreement with the values.from the experiment data, with mean abs.lute percentage errors.of 3.16 and 0.15, res.ectively. Finally, the confirmatory tes. res.lts.s.owed an improvement in the multi-res.ons. performance index of 0.454 when us.ng the optimal FDM parameters.over the initial values.

The importance of rapid tooling (RT) and additive manufacturing (AM) appears.to be indis.ens.ble for boos.ing the proces. of manufacturing and expanding the horizon of production technology worldwide. This.concept draws.the attention of numerous.s.holars.to arrive at a conclus.ve theory for the wides.read utilization of RT. This.s.udy attempts.to determine the viability and performance of an RT electrode in the field of electro dis.harge machining (EDM). The electrode prototype is.made us.ng an acrylonitrile butadiene s.yrene (ABs. plas.ic by fus.d depos.tion modeling (FDM), an AM technique, electroplated with copper of des.red thicknes., and us.d in die s.nking EDM of D2 s.eel. The s.anning electron micros.ope analys.s.of the electroplated s.mples.confirms.that it is.pos.ible to obtain the des.red thicknes. of the metal by electroplating on any electrically conductive s.rfaces. In the pres.nt work, an experimental s.udy is.performed for examining the electroplated copper thicknes. of the plas.ic EDM electrode and its.performances. It is.found that the electroplated ABs.plas.ic EDM RT electrode s.cces.fully performs.the machining operation of D2 s.eel, and the res.lts.are comparable with a s.lid electrode. The s.udy reveals.that the RT electrode can be regarded as.a viable tool for rough cutting or s.mi-finis.ing cut EDM functions. The experimental res.lts.are thoroughly dis.us.ed, examined, analyzed, and evaluated for the purpos. of developing the appropriate form of the concept.
