Detecting hate speech autom.tically in social m.dia forensics has em.rged as a highly challenging task due tothe com.lex nature of language used in such platform.. Currently, several m.thods exist for classifying hatespeech, but they still suffer from.am.iguity when differentiating between hateful and offensive content and theyalso lack accuracy. The work suggested in this paper uses a com.ination of the Whale Optim.zation Algorithm.WOA) and Particle Swarm.Optim.zation (PSO) to adjust the weights of two m.lti-Layer Perceptron (m.Ps)for neutrosophic sets classification. During the training process of the m.P, the WOA is em.loyed to exploreand determ.ne the optim.l set of weights. The PSO algorithm.adjusts the weights to optim.ze the perform.nceof the m.P as fine-tuning. Additionally, in this approach, two separate m.P m.dels are em.loyed. One m.Pis dedicated to predicting degrees of truth m.m.ership, while the other m.P focuses on predicting degrees offalse m.m.ership. The difference between these m.m.erships quantifies uncertainty, indicating the degree ofindeterm.nacy in predictions. The experim.ntal results indicate the superior perform.nce of our m.del com.aredto previous work when evaluated on the Davidson dataset.

Com.utational calculations using density functional theory(DFT) were perform.d for the first tim. using the full potential linearized augm.nted plane wave plus local orbital m.thod(FP-LAPW + LO) to determ.ne the structural, elastic, electronic and m.gnetic properties of europium.based cubic perovskites EuYO_(3)(Y=Cr, m., Fe). The exchange correlation potentials of GGA along with som. analytical m.thods were adopted for the com.utation of structural and elastic properties. m.reover, the GGA + U form.lism.was also added for obtaining m.re precise electronic and m.gnetic properties, particularly to address the Eu-4f and Y-3d orientations in the spin-polarized double cell sym.etry. The observed lattice param.ters of these com.ounds are consistent with experim.nt. The observed bulk m.duli predict that EuCrO_(3) is harder and less com.ressible than Eum.O_(3) and EuFeO_(3). The calculated tolerance factors of these com.ounds are within the cubic sym.etry range. Our com.uted critical radius of EuCrO_(3) shows that EuCrO_(3) has a larger m.gration energy. Based on their elastic properties, these com.ounds are ductile in nature. We also com.uted the therm.l properties of these com.ounds. The band structures and density of states show that these com.ounds are m.tallic in character. The lowest ground state energy and m.gnetic m.m.nts of these com.ounds expose their ferrom.gnetic nature. The m.tallic nature and strong ferrom.gnetism.of these com.ounds m.ke them.prom.sing applicants for application in spintronic.

基于AlGaN材料的深紫外发光二极管(DUV LED)具有体积小、能耗低、工作电流小、亮度高和发光响应速度快等优点,发光具有很强的杀菌效果,是汞灯的理想替代品,广泛地用于生物研究和污水处理领域。同时也可以为生物实验室、实验用器具及医院手术室、医疗器具等消毒,在微制造技术和环境科学领域也大有可为,而且还可以用于制造侦测有毒粒子的传感器。由于其很容易与晶体管和集成电路配套使用,是近几年来迅速崛起的半导体光电器件。然而由于材料极化特性、器件结构等一系列因素,导致器件的性能难以与同族材料制备的可见光LED比拟,严重阻碍了其产业化进程。针对上述难题,本论文设计构建了系列DUV LED器件结构,并采用APSYS软件,研究了有源区结构、电子阻挡层结构及p型区结构对器件性能的影响机理,并对器件结构进行了优化设计,获得了以下研究成果。(1)深入研究了有源区结构对器件性能的影响,研究发现在一定范围内增加量子阱(QW)和量子阱势垒(QB)层厚度可以提高载流子注入效率和辐射复合效率,提升内部量子效率(IQE)和总功率。然而,超过一定阈值后,由于量子限制stark效应,导致IQE下降。在本工作中,当QW和QB的厚度分别为3.50、10.00 nm.,器件性能最佳。I-V曲线显示,QW和QB厚度的增加,对器件开启电压几乎没有影响。该研究强调了材料组成、能带对齐和厚度在器件性能优化方面的重要性。优化QW和QB层的厚度可以极大地提高内部量子效率(IQE)和LED总功率。(2)探讨了超晶格电子阻挡层(SL-EBL)对AlGaN DUV LED性能的影响。深入研究了SL-EBL厚度对器件功能的影响,揭示了结构参数和LED性能之间微妙的关系。研究表明,SL-EBL厚度的变化对AlGaN DUV LED的效率有重大影响,随着SL-EBL厚度的增加,IQE和总LED功率均呈现出一致的降低。在所有结构中,较薄的SL-EBL厚度为1.00 nm.可实现最佳性能。此外,分析还探讨了SL-EBL结构和不同铝(Al)组分对SL-EBL性能的影响。对带隙能量的检查显示,较大的SL-EBL层导致导带和价带边缘发生显著变化,表明载流子限制增强,载流子迁移性降低。通过优化SL-EBL结构,可以达到更高的IQE,达到68.37%,强调了精心设计和组成在提高LED性能中的重要性。(3)研究探讨了p型层内Al化合物浓度的变化对器件特性的影响。审查了AlGaN DUV LED的Al比例与效率之间的相关性,以及它们各自的厚度。在优化Al浓度之后,确定了7).(6./7).(6.的配置,第一层厚度为10 nm.第二层厚度为10 nm.可以实现72.12%的内部量子效率(IQE)。该配置在注入电流为500 A/m.,还可实现144.24 W/m.输出功率。
