The design of iterative learning controller(ILC) requires to store the system input, output or control parameters of previous trials for generating the input of the current trial. In order to apply the iterative learning controller for a real application and reduce the memory size for implementation, a current error based sampled-data proportional-derivative(PD) type iterative learning controller is proposed for control systems with initial resetting error, input disturbance and output measurement noise in this *** proposed iterative learning controller is simple and effective. The first contribution in this paper is to prove the learning error convergence via a rigorous technical analysis. It is shown that the learning error will converge to a residual set if a forgetting factor is introduced in the controller. All the theoretical results are also shown by computer simulations. The second main contribution is to realize the iterative learning controller by a digital circuit using a field programmable gate array(FPGA) chip applied to repetitive position tracking control of direct current(DC) motors. The feasibility and effectiveness of the proposed current error based sampleddata iterative learning controller are demonstrated by the experiment results. Finally, the relationship between learning performance and design parameters are also discussed extensively.

Low-duty-cycle mechanisms can reduce the energy consumption significantly in wireless sensor networks（WSNs）. Sensors stay dormant most of the time to save their energy and wake up based on their needs. However, such a technique, while prolonging the network lifetime, sets excessive challenges for reducing the end-to-end（E2E） delay within the network. In this paper, the centralized cluster-based location finding（CCLF） algorithm is proposed to reduce the high latency in low-duty-cycle WSNs by finding a suitable position for the sink. The algorithm is mainly composed of three steps： a） the cluster construction, b） the fast look-up table（FLU-table） construction, and c） the sink location decision. The simulation results show that the performance of the CCLF algorithm is significantly similar to that of the optimal algorithm. Moreover, the CCLF algorithm requires less operation time compared with the optimal algorithm.

近年来,报考马来西亚高级教育文凭考试的考生人数逐年下降。华文科是这项考试的科目之一,近五年来的华文科考生,每年都没有超过300人。中六华文是学生报读国内大学中文系的主要条件之一。中六华文考生减少意味着大学中文系学生来源受到冲击,长期而言,这种趋势将影响全国中小学华文师资的栽培。学生不愿在这项考试中选考华文,原因很多。其中最大的问题在于学生觉得中六华文课程内容太广,而中国古代文学史的部分最难学习。因此,本文尝试探讨中六学生在学习古代文学史所面对的难点及提出解决问题的建议。本文对马来西亚雪兰莪州加影育华国民型华文中学2021年中六第二学期及第三学期的华文班学生展开问卷调查,并对该校的中六华文教师进行访谈。根据所得的资料,本文从古代文学史教材、课程内容及考试格式三方面探讨了学生学习古代文学史的难点。这些难点包括文学史课程内容庞杂、作家作品繁多、文学史教材内容生涩难懂、文学史课程内容枯燥而脱离现实生活及文学史考试格式倾向应试教育。这些学习难点使学生无法掌握文学史的知识而考获差强人意的成绩。本文也分析了导致学生学习古代文学史困难的原因:这些原因包括学生的古诗文基础薄弱、对文学史没有兴趣、不够自律、学习时间太短、考试范围太广、教师文学知识不足及教学法枯燥无味。针对这些难点与相关原因,本文从建构主义教学与学习理论的视角提出了一些相应对策。这些对策包括:提升学生的文学知识以建构新的知识、创设情境以激发学生学习兴趣、互动合作以提高自主建构效果、提升语文教师的专业知识及鼓励学生自主学习。本文也建议在这项考试的课程范围内删除古代文学史项目并以增加古代文选篇章代替,并且改革文学史的考题格式。在马来西亚,开办中六华文班的学校不多,而选读中六华文的考生也很少,因此,国内有关中六华文教学的研究与论文几乎一片空白。通过这项研究,作者希望可以抛砖引玉,引起更多教育工作者的注意,鉴定与解决中六学生学习文学史所面对的问题,提高学生对文学史的兴趣,吸引更多学生选读华文,以培育未来中小学的师资。

Drought is a common natural disaster worldwide, with varying durations, severity levels, and spatial extents. This study aimed to model the spatiotemporal variation of meteorological drought events in the Gabiley region of Somaliland. The study utilized primary data collected from the meteorological station in Gabiley and CHIRPS (Climate Hazards Group InfraRed Precipitation with Station) data to develop the standardized precipitation index (SPI) at a 3-month timescale. The results of the study revealed that the study area was characterized by drought and received inadequate precipitation, resulting in catastrophic droughts that negatively impacted the socioeconomic situation of the community. Mild-to-severe meteorological drought events occurred every two to three years, with the most severe droughts occurring in 1998, 2002, 2009, 2015, and 2017. Specifically, the year 2015 experienced the most severe meteorological drought in the region during the studied period. The predominant type of drought was a mild year in the study area. The SPI was found to potentially identify meteorological drought, making it a useful tool for policymakers as they develop drought adaptation and mitigation policies. This study provides valuable information that can benefit local authorities and policymakers in creating drought mitigation and adaptation strategies in the Gabiley region.
