Optimal Design of Fault-Tolerant Controller for an Electric Power Steering System with Sensor Failures Using Genetic Algorithm by Xue Liu, Hui Pang, Yuting Shang, Wen Wu

“…A mathematical model of the EPS system with sensor failures is first established, and the state feedback control law is solved by using linear quadratic regulator techniques to stabilize the closed-loop control system. Then, the dynamic response errors of the EPS system with and without sensor faults are chosen as the optimization objective function. …”

The three-dimensional N $$ \mathcal{N} $$ = 2 superfishnet theory by Moritz Kade

“…We use techniques inspired by the integrability of bi-scalar fishnet theory and adapted to superspace to calculate the zero-mode-fixed thermodynamic free energy, the corresponding critical coupling, and the exact all-loop scaling dimensions of various operators. Furthermore, we confirm the results of the supersymmetric dynamical fishnet theory by applying our methods to four-dimensional N $$ \mathcal{N} $$ = 1 superspace.…”

Heavy Flavour Energy Loss in Small and Large Systems by Faraday Coleridge, Horowitz W. A.

“…We observe that suppression in small systems is almost entirely due to elastic energy loss; furthermore, we find that our model is acutely sensitive to the transition between hard thermal loop and vacuum propagators in the elastic energy loss. …”

Holographic Phase Transition Probed by Nonlocal Observables by Xiao-Xiong Zeng, Li-Fang Li

“…From the viewpoint of holography, the phase structure of a 5-dimensional Reissner-Nordström-AdS black hole is probed by the two-point correlation function, Wilson loop, and entanglement entropy. As the case of thermal entropy, we find for all the probes that the black hole undergoes a Hawking-Page phase transition, a first-order phase transition, and a second-order phase transition successively before it reaches a stable phase. …”

Effects of the Variation of SUSY Breaking Scale on Yukawa and Gauge Couplings Unification by Konsam Sashikanta Singh, N. Nimai Singh

“…The rising of the unification scale and also the mass of the color triplet multiplets is necessary to increase the proton decay lifetime; the analysis is carried out with two-loop RGEs for the gauge and Yukawa couplings within the minimal supersymmetric SU(5) model, while ignoring for simplicity the threshold effects of the heavy particles, which could be as large as a few percentages.…”

Chaotic Behavior in a Switched Dynamical System by Fatima El Guezar, Hassane Bouzahir

“…Precisely, we study the chaotic dynamics of the voltage-mode controlled buck converter circuit in an open loop. By considering the voltage input as a bifurcation parameter, we observe that the obtained simulations show that the buck converter is prone to have subharmonic behavior and chaos. …”
