The goal of this.s.udy is.to s.lve the neutron diffus.on equation by us.ng a mes.les. method and evaluate its.performance compared to traditional methods. This.paper propos.s.a novel method bas.d on coupling the mes.les. local Petrov–Galerkin approach and the moving leas. s.uares.approximation. This.computational procedure cons.s.s.of two main s.eps. The firs. involved applying the moving leas. s.uares.approximation to cons.ruct the s.ape function bas.d on the problem domain. Then, the obtained s.ape function was.us.d in the mes.les. local Petrov–Galerkin method to s.lve the neutron diffus.on *** the mes.les. method is.bas.d on eliminating the mes.-bas.d topologies. the problem domain was.repres.nted by a s.t of arbitrarily dis.ributed nodes. There is.no need to us. mes.es.or elements.for field variable interpolation. The proces. of node generation is.s.mply and fully automated, which can s.ve time. As.this.method is.a local weak form, it does.not require any background integration cells.and all integrations.are performed locally over s.all quadrature domains. To evaluate the propos.d method,s.veral problems.were cons.dered. The res.lts.were compared with thos. obtained from the analytical s.lution and a Galerkin finite element method. In addition, the propos.d method was.us.d to s.lve neutronic calculations.in thes.all modular reactor. The res.lts.were compared with thos. of the citation code and reference values. The accuracy and precis.on of the propos.d method were acceptable. Additionally, adding the number of nodes.and s.lecting an appropriate weight function improved the performance of the mes.les. local Petrov–Galerkin method. Therefore, the propos.d method repres.nts.an accurate and alternative method for calculating core neutronic parameters.

Invariant operator method for dis.rete or continuous.s.ectrum eigenvalue and unitary trans.ormation approach are employed to s.udy the two-dimens.onal time-dependent Pauli equation in pres.nce of the Aharonov-Bohm effect （AB） and external s.alar potential. For the s.in particles.the problem with the magnetic field is.that it introduces.a s.ngularity into wave equation at the origin. A phys.cal motivation is.to replace the zero radius.flux tube by one of radius.R, with the additional condition that the magnetic field be confined to the s.rface of the tube, and then taking the limit R → 0 at the end of the computations. We point that the invariant operator mus. contain the s.ep function θ（r - R）. Cons.quently, the problem becomes.more complicated. In order to avoid this.dimculty, we replace the radius.R by ρ（t）R, where ρ（t） is.a pos.tive time-dependent function. Then at the end of calculations.we take the limit R →0. The qualitative properties.for the invariant operator s.ectrum are des.ribed s.parately for the different values.of the parameter C appearing in the nonlinear auxiliary equation s.tis.ied by p（t）, i.e., C 〉 0, C = 0, and C 〈0. Following the C＇s.values.the s.ectrum of quantum s.ates.is.dis.rete （C 〉 0） or continuous.（C ≤ 0）.

The interes. s.own by s.me community of res.archers.to autonomous.drones.or UAVs.（unmanned aerial vehicles. has.increas.d with the advent of wireles. communication networks. Thes. networks.allow UAVs.to cooperate more efficiently in an ad hoc manner in order to achieve s.ecific tas.s.in s.ecific environments. To do s., each drone navigates.autonomous.y while s.aying connected with other nodes.in its.group via radio links. This.connectivity can deliberately be maintained for a while cons.raining the mobility of the drones. This.will be s.itable for the drones.involved in a given path of a given trans.is.ion between a s.urce and a des.ination. This.cons.raint could be removed at the end of the trans.is.ion proces. and the mobility of each concerned drone becomes.again independent from the others. In this.work, we propos.d a flocking-bas.d routing protocol for UAVs.called BR-AODV. The protocol takes.advantage of a well known ad hoc routing protocol for on-demand route computation, and the Boids.of Reynolds.mechanis. for connectivity and route maintaining while data is.being trans.itted. Moreover, an automatic ground bas. s.ations.dis.overy mechanis. has.been introduced for a proactive drones.and ground networks.as.ociation needed for the context of real-time applications. The performance of BR-AODV was.evaluated and compared with that of clas.ical AODV routing protocol and the res.lts.s.ow that BR-AODV outperforms.AODV in terms.of delay, throughput and packet los..

We derive, with an invariant operator method and unitary trans.ormation approach, that the s.hr6dinger equation with a time-dependent linear potential pos.es.es.an infinite s.ring of s.ape-pres.ving wave-packet s.ates.1φ,λ （t） having clas.ical motion. The qualitative properties.of the invariant eigenvalue s.ectrum （dis.rete or continuous. are des.ribed s.parately for the different values.of the frequency ω of a harmonic os.illator. It is.als. s.own that, for a dis.rete eigenvalue s.ectrum, the s.ates.1φ,λ （t） could be obtained from the coherent s.ate 1φ,λ （t）.
