针对光伏逆变器的绝缘栅双极型晶体管(insulated gate bipolar transistor,IGBT)接线故障不易发现且易被忽略,现有方法诊断速度慢、识别率低的问题,提出了一种基于电压均值的特征提取策略,并利用改进狮群算法(improved loin sw.rm optimization,ILSO)优化核极限学习机(kernel extreme learning machine,KELM),实现对IGBT的故障诊断.首先,分析逆变器各状态下三相电压Concordia变换后的效果,获得表征故障特征的二维向量,通过二维散点图验证接线故障的可分性;其次,通过Sine混沌映射改进的狮群算法(loin sw.rm optimization,LSO)对KELM进行参数寻优,建立诊断模型;最后,以z源逆变器为例进行验证.结果表明:对于逆变器的IGBT接线故障,所提方法能提取包含丰富故障信息的二维故障特征,极大地简化了特征提取的过程,且诊断方法适用于单个和2个器件的故障类型,与其他方法相比速度更快,故障识别率更高.

立体定向放疗(stereotactic body radiation therapy,SBRT)技术以其精准性和高效率在肝癌的治疗中发挥着日益重要的作用,而相应的临床教学内容却相对单薄,缺乏更新与完善。为了提升肝癌立体定向放疗的临床教学水平,引入了人工智能(artificial intelligence,AI)技术。首先,AI可以辅助更精确地筛选适合SBRT治疗的肝癌患者;其次,AI可以根据历史治疗数据和最新的临床研究,提供联合治疗方案的最佳组合;此外,AI还可以通过深度学习算法完善靶区的自动勾画及优化物理计划,确保治疗效果的最大化;最后,AI能够通过分析系统数据,预测放射性肝损伤风险,为临床医生提供更为合理的治疗建议。因此,人工智能技术的引入,不仅提高了肝癌立体定向放疗的临床效果,同时也为教学内容的丰富性和前瞻性提供了强大支持,有望在促进临床教学创新的同时,改善肝癌患者的治疗结果。

A low.complex minimum mean-square error frequency-domain decision feedback （MMSE-FDDF） equalization algorithm is proposed in this paper for the single-carrier V-BLAST systems. Exploiting the factor that the discrete Fourier transform （DFT） is unitary, the proposed receiver can equalize the signals by the MMSE detecting to the spectrums in the frequency domain instead of the w.veforms in the time domain. In order to obtain the right decisions, the detector must be able to equalize the overall spectrum w.th regard to each layer. This w.rk can be performed very efficiently since the system matrix has been designed as a special block-circulant-block matrix. Similar to other V-BLAST-like systems, the detecting order has strong impact on the performance of MMSE-FDDF. Therefore, w. further give a fast optimally sorting scheme for the MMSE-FDDF architecture. By using the new.y constructed matrix, the coefficients computation and the sorting can be combined into one process, and then w. employ the modified Gram-Schmidt （MGS） to simplify the process. The simulation results and the computational complexity analysis show.that the proposed MMSE-FDDF has better tradeoff betw.en the performance and the complexity than the existing algorithms. In addition, MMSE-FDDF can avoid the performance floor caused by the overlap-and-save technique in the severe dispersive channel.

为探究不同结构形式航道骨架护岸结构的稳定性影响规律,选择出最佳护岸结构形式,并对该形式进行结构优化,结合沙河漯河—平顶山航运工程的实际情况,利用PLAXIS 3D分别建立了几种护坡的三维结构模型。结果表明:在人字形、菱形、拱形骨架3种形式中,使用拱形骨架时,岸坡的滑动破坏面范围最小,岸坡的安全系数最大;在设计拱形骨架护岸结构时,应首先考虑不同拱径对岸坡土体位移的影响,在对岸坡土体沉降控制较严格的工程上,可进一步考虑不同拱宽的设计取值对其不同影响;本工程建议拱形骨架护岸结构的设计参数由原设计方案(拱径2.5 m、拱宽0.05 m、埋深0.300 m)优化为正交方案(拱径4.5 m、拱宽0.05 m、埋深0.450 m),在减小岸坡土体位移的同时仅增加不到55 m3的混凝土用量。
