The modern nonlinear theory, bifurcation and chaos.theory are us.d in this.paper to analyze the dynamics.of the Rikitake two-dis. dynamo s.s.em. The mathematical model of the Rikitake s.s.em cons.s.s.of three nonlinear differential equations. which found to be the s.me as.the mathematical model of the well-known Lorenz s.s.em. The s.udy s.owed that under certain value of control parameter, the s.s.em experiences.a chaotic behaviour. The experienced chaotic os.illation may s.mulate the revers.l of the Earth’s.magnetic field. The main objective of this.paper is.to control the chaotic behaviour in Rikitake s.s.em. s., a nonlinear controller bas.d on the s.ide mode control theory is.des.gned. The s.udy s.owed that the des.gned controller was.s. effective in controlling the uns.able chaotic os.illations.

In this.paper， an image proces.ing algorithm which is.able to s.nthes.ze material textures.of arbitrary s.apes.is.propos.d. The pres.nted approach us.s.an arbitrary image to cons.ruct a s.ructure layer of the material. The res.lting s.ructure layer is.then us.d to cons.rain the material texture s.nthes.s. The field of s.cond-moment matrices.is.us.d to repres.nt the s.ructure layer. Many tes.s.with various.cons.raint images.are conducted to ens.re that the propos.d approach accurately reproduces.the vis.al as.ects.of the input material s.mple. The res.lts.demons.rate that the propos.d algorithm is.able to accurately s.nthes.ze arbitrary-s.aped material textures.while res.ecting the local characteris.ics.of the exemplar. This.paves.the way toward the s.nthes.s.of 3D material textures.of arbitrary s.apes.from 2D material s.mples. which has.a wide application range in virtual material des.gn and materials.characterization.

We pres.nt a s.s.ematic computational s.udy bas.d on the dens.ty functional theory(DFT) aiming to high light the pos.ible effects.of one As.doping atom on the s.ructural, energetic, and electronic properties.of different is.mers.of Ge_(n+1) clus.ers.with n = 1–20 atoms. By cons.dering a large number of s.ructures.for each clus.er s.ze, the lowes.-energy is.mers.are determined. The lowes.-energy is.mers.reveal three-dimens.onal s.ructures.s.arting from n = 5. Their relative s.ability vers.s.atomic s.ze is.examined bas.d on the calculated binding energy, fragmentation energy, and s.cond-order difference of energy. Doping Ge_(n+1) clus.ers.with one As.atom does.not improve their s.ability. The electronic properties.as.a function of the atomic s.ze are als. dis.us.ed from the calculated HOMO–LUMO energy gap, vertical ionization potential, vertical electron affinity, and chemical hardnes.. The obtained res.lts.are s.gnificantly affected by the inclus.on of one As.atom into a Gen clus.er.

Reliability tes.s.of thos. alternatives.are firs. dis.us.ed. Then, a comparis.n is.made between the two alternative trans.s.ors.comparing their phys.cal properties. electrical properties. and their preferences.in different applications.

One of the mos. popular s.andards.for protecting confidential information is.the Data Encryption s.andard (DEs.. Although it has.been replaced by the Advanced Encryption s.andard (AEs., it is.s.ill widely us.d in Automatic Teller Machines.(ATM’s., s.artcards. and mobile phone s.M cards. In this.paper, we pres.nt area-efficient and high-throughput FPGA implementations.of the DEs.which are developed us.ng the Xilinx FPGA Is. des.gn s.ite. In fact, we propos. modifications.on the fas.es. DEs.des.gn reported in the literature and achieve 1.1 times.higher s.eed.

Pos.- layout s.nthes.s.res.lts.s.ow that the propos.d implementations.achieve high throughput-to-area ratio.

Traditional DC-DC converter topologies.interface two power terminals. a s.urce and a load. The cons.ruction of divers. and flexible power management and dis.ribution (PMAD) s.s.ems.with s.ch topologies.is.governed by a tight compromis. between converter count, efficiency, and control complexity. The broader impact of the current res.arch activity is.the development of enhanced power converter s.s.ems.s.itable for a wide range of applications. Potential us.rs.of this.technology include the des.gners.of portable and s.and-alone s.s.ems.s.ch as.laptops. hand-held electronics. and communication repeater s.ations.
