为了恢复几乎被20世纪中期城市改造政策毁掉的一片城区,美国职业足球联盟球场——“城市公园”球场耗资4.5亿美元建成。位于圣路易斯市中心西侧于去年投用的新建专用英式足球场与美国目前在建的大多数体育场馆截然不同。这个拥有22423个座位的球场被称为“城市公园”(CityPark),使用了相对较少的公共补贴,它也作为美国职业足球大联盟(MLS)球队圣路易斯城足球俱乐部队主场的球场,呈现在人们面前的并不是那种被停车场包围的巨型建筑,而是不遗宗力要成为周边社区好邻居的形象。

针对无位置传感器轮毂电机比例积分(Proportion Integration,PI)控制中常见的抗干扰能力差、计算量大、控制精度不高等问题,提出一种粒子群-天牛须(Beetle Antennae Search-Particle Swarm Optimization,BAS-PSO)算法,在模型参考自适应系统(Model Reference Adaptive System,MRAS)观测电机转速与位置的基础上,实现转速控制器的PI参数自整定。建立永磁同步轮毂电机(Permanent Magnet Synchronous Motor,PMSM)的数学模型,以转速环传递函数的时间绝对误差积分指标(Integrated Time Absolute Error,ITAE)作为适应度函数,通过BAS-PSO算法优化转速控制器的PI参数;MRAS将电机本身作为参考模型,将含有待估计参数的定子电流方程作为可调模型,基于Popov超稳定理论,设计合适的自适应律,估计电机的转速与位置;利用Matlab/Simulink进行仿真对比,并在HIL平台进行硬件测试验证。结果表明:与传统方法相比,BAS-PSO算法能够提高电机的运行响应速度,降低转速超调量,提高系统的鲁棒性。

Introduction: Urogenital prolapse is the descent of one or more elements of the abdominal-pelvic contents into the vaginal cavity. The anterior, middle and posterior anatomical compartments may be involved giving rise to several types of genital prolapse. However, there are various therapeutic modalities ranging from observational procedures to surgery. In Yaounde, urogenital prolapse appears to be a rare clinical entity, and its treatment has not been clearly stated. There is limited data about this subject in our context. Our aim was to study the clinical and therapeutic aspects of urogenital prolapse in Yaounde. Methods: We conducted a descriptive cross-sectional study with retrospective data collection at the Yaounde Gynaecological Obstetric and Pediatric Hospital (YGOPH) and the Yaounde Central Hospital (YCH) over a period of 05 months (from February 2022 to June 2022). All women aged ≥30 years and all women with documented urogenital prolapse admitted to the maternity and urology departments of these two health facilities were included. Data were collected using a structured questionnaire. Data was analyzed using IBM SPSS (statistical package for social sciences) software version 23.0 and the data were reported as mean, standard deviation, frequencies and percentages. Results: A total of 50 patients were recruited;the mean age was 45.8 ± 17 years. The age range was from 21 to 72 years. Majority of the patients were aged more than 55 years (32%). Most of the patients attended primary education (48%). Forty percent of the patients were housewives. The majority of the patients were from West Cameroon (26%). The most common reason for consultation was pelvic heaviness (54%). The most prevalent clinical sign was cystocele (56%), followed by hysterocele (54%). According to the Baden Walker classification, one-third of the patients were classified as first degree (36%). More than half (58%) of patients had the condition located at the first stage.
