Rainfall variability associated with climate change has enormous impacts on ecosystems, agriculture and people in West Africa but few studies have been devoted to it. Monthly rainfall data from 1901 to 2013, provided by the Global Precipitation Climatology Center dataset, were analyzed using segmentation and empirical modal decomposition (EMD) methods to increase our knowledge on past and recent spatio-temporal rainfall trends and their impacts on the West African region. The results obtained showed that the peak of rainfall during the short rainy season is observed in September in Côte d’Ivoire, Ghana and liberia. The temporal variability of this rainfall is marked by several breakpoints whose durations range from 2 to 70 years. The periods of change in the rainfall regime, characterized by the appearance of breakpoints, vary from one country to another and are of unequal duration. The main breakpoint appears after 1960. Periods of relative or normal increase or decrease in precipitation are observed before and after 1960. The long-term variability of this rainfall is characterized by a decrease in the amount of rainfall over all West African countries. The results of this study can be used as a tool to help raise awareness among populations for sustainable management of water resources in response to climate change and its adverse effects.

针对集装箱配载问题的复杂性,提出了集装箱船在一个航次中挂靠多个港口的混装Bay位的排箱模型.该模型以例箱量最少为目标,忽略集装箱的尺寸及箱内货物类型等因素,仅考虑倒箱对配载的影响.以Bay位某列是否存在倒箱为设计变量,以全航线倒箱数量最少为目标建立优化模型,并利用隐式图启发式搜索技术对各个港口的集装箱进行安排.计算机模拟结果表明,所提出模型能快速产生倒箱数最少的全航线Bay位排箱方案.

作为一种非侵入式诊疗方式,帕金森症患者的语音可用于该病症的早期诊断和跟踪治疗。在基于语音的统一帕金森病评定量表（UPDRS）预测中,现有研究只考虑了性别对预测结果的影响。为提升基于语音的帕金森症诊疗方案的准确度和有效性,对已有的帕金森症患者语音数据进行回归预测并分析获取数据的内在规律。在此基础上,提出一种使用基于过滤的域适应模型融合方法,该方法考虑了不同患者间病情发展趋势和严重程度的差异性及差异之间的不平衡性,将与待测对象差异较大的已知对象数据过滤,对剩余的数据使用域适应模型融合来构建准确的UPDRS预测模型。将该方法在现实数据集上与现有方法进行了对比,实验结果表明,方法能获得更好的预测性能。

This paper reports morbidity of endemic cretinism in endemic areas of 3 agricultural communes in southeastern and southern Guizhou. They were 3.1%, 2.8% and 5.2% in 1979. Retardation of physical development before 7 years of age is seen. Thyroid gland biopsy shows hyperplasia; point patches are scattered in scans and γ-scintiscans and there are cold and warm nodules. The surface area of thyroid gland is either normal, decreased or increased. There is mental retardation in all patients. The deaf-mutism or cerebral palsy is a characteristic of neural deficit. The roentgenographic features are delayed bony age and late ossification center of the femoral head. In this group iodine uptake of thyroid gland is increased apparently, urine iodine 25 μg/gm cretinine, serum T4 4.1 μg/dl, TSH 36.3 μU/ml. This group shows both severe psychoneurologic defects and evident hypothyroidism without myxedema, and is classified as the so-called mixed type of cretinism.

针对变量施肥系统因土壤平整度、机车行进速度等因素变化,导致施肥轮转速不稳定,影响施肥效果的问题,在传统PID控制器的基础上,设计了电控机械无级变速机构(CVT)变量施肥系统模糊自整定PID控制器。采用MATlAB/Simulink仿真,对比传统PID和模糊自整定PID系统的阶跃信号响应和脉冲干扰信号响应,结果表明:模糊自整定PID控制器在响应速度、超调量及抑制干扰能力等方面均优于传统PID,并通过试验进一步验证控制效果。
