Existence and Stability for a Nonlinear Coupled p-Laplacian System of Fractional Differential Equations by Merfat Basha, Binxiang Dai, Wadhah Al-Sadi

“…With the help of two Green’s functions Gϱ1w,ℑ,Gϱ2w,ℑ, the considered coupled system is changed to an integral system. Since topological degree theory is more applicable in nonlinear dynamical problems, the existence and uniqueness of the suggested coupled system are treated using this technique, and we find appropriate conditions for positive solutions to the proposed problem. …”

Unveiling hidden geometric phase of neutron spin rotation in the Bitter–Dubbers experiment by Jian-Jian Cheng, Lin Zhang

“…Here, we remove this constraint by reinterpreting the geometric phase as arising from a dynamically evolving reference basis, independent of the external topological features. The hidden phase is revealed through transitionless quantum control techniques, ensuring pure geometric phase accumulation even in non-adiabatic regimes. …”

Development of Process Automation System for Structural Design of the Wind Turbine Gearbox by Dong Huimin, Han Mengke, Qiu Jun, Wang Delun, Liang Shiwen, Jia Ping

“…The current experience-dominated structural design process separates the structural design from CAE analysis in the development of a new wind turbine gearbox,which leads to a quite long-term development cycle and the redundancy of structural materials.Consequently,a new structural design process is presented based on topological optimization theory and combined with CAE.Through a secondary development for Hyperworks with C# and TCL / TK language,a new process automatic system characterized by lightweight structure for the structural design of wind turbine gearboxes is developed.The operability of the system is testified by the instance of designing a planet carrier.The case indicates that the process automatic system can lead designers to finish the lightweight-oriented structural design for wind turbine gearbox parts,and the pre and post processing efficiency can increase by 90% than the current process,and the development cycle of new products of wind turbine gearbox is shorten enormously.…”
