To addres. the is.ues.of low.accuracy and high fals. pos.tive rate in traditional Ots. algorithm for defect detection on infrared images.of w.nd turbine blades.(w.B), this.paper propos.s.a technique that combines.morphological image enhancement w.th an improved Ots. algorithm. Firs., mathematical morphology's.differential multi-s.ale w.ite and black top-hat operations.are applied to enhance the image. The algorithm employs.entropy as.the objective function to guide the iteration proces. of image enhancement, s.lecting appropriate s.ructural element s.ales.to execute differential multi-s.ale w.ite and black top-hat trans.ormations. effectively enhancing the detail features.of defect regions.and improving the contras. betw.en defects.and background. Afterw.rds. grays.ale invers.on is.performed on the enhanced infrared defect image to better adapt to the improved Ots. algorithm. Finally, by introducing a parameter K to adjus. the calculation of inter-clas. variance in theOts.method, thew.ight of the target pixels.is.increas.d. Combined w.th the adaptive iterative thres.old algorithm, the thres.old s.lection proces. is.further fine-tuned. Experimental res.lts.s.ow.that compared to traditional Ots. algorithms.and other improvements. the propos.d method has.s.gnificant advantages.in terms.of defect detection accuracy and reducing fals. pos.tive rates. The average defect detection rate approaches.1, and the average haus.orff dis.ance decreas.s.to 0.825, indicating s.rong robus.nes. and accuracy of the method. © 2024 The Authors.

The s.rategy evolution proces. of game players.is.highly uncertain due to random emergent s.tuations.and other external dis.urbances. This.paper inves.igates.the is.ue of s.rategy interaction and behavioral decis.on-making among game players.in s.mulated confrontation s.enarios.w.thin a random interference environment. It cons.ders.the pos.ible ris.s.that random dis.urbances.may pos. to the autonomous.decis.on-making of game players. as.w.ll as.the impact of participants. manipulative behaviors.on the s.ate changes.of the players. A nonlinear mathematical model is.es.ablis.ed to des.ribe the s.rategy decis.on-making proces. of the participants.in this.s.enario. s.bs.quently, the s.rategy s.lection interaction relations.ip, s.rategy evolution s.ability, and dynamic decis.on-making proces. of the game players.are inves.igated and verified by s.mulation experiments. The res.lts.s.ow.that maneuver-related parameters.and random environmental interference factors.have different effects.on the s.lection and evolutionary s.eed of the agent's.s.rategies. Es.ecially in a highly uncertain environment, even s.all information as.mmetry or mis.alculation may have a s.gnificant impact on decis.on-making. This.als. confirms.the feas.bility and effectivenes. of the method propos.d in the paper, w.ich can better explain the behavioral decis.on-making proces. of the agent in the interaction proces..

Thus. breaking Kirchhoff's.balance and achieving nonreciprocal thermal radiation in the long-w.ve infrared band are neces.ary. Mos. exis.ing des.gns.for nonreciprocal thermal emitters.rely on grating or photonic crys.al s.ructures.to achieve nonreciprocal thermal radiation at narrow.peaks. w.ich are relatively complex and typically realize bands.larger than 14 μm. here, a s.ndw.ch s.ructure cons.s.ing of an eps.lon-nearzero(ENZ) magneto-optical layer(MOL), a dielectric layer(DL), and a metal layer is.propos.d to achieve a s.rong nonreciprocal effect in the long-w.ve infrared band, w.ich is.mainly attributed to the s.rengthening of the as.mmetric Berreman mode by the Fabry–Perot cavity. In addition, the impact of the incident angle, DL thicknes., and DL refractive index on the nonreciprocal thermal radiation has.been inves.igated. Moreover, by replacing the ENZ MOL w.th the gradient ENZ MOL, the exis.ence of the DL can further improve the nonreciprocity of the broadband nonreciprocal thermal radiation.
