1基于博弈论赋权的灌溉用水效率GRA-TOPSIS评价模型显示文摘在构建区域灌溉用水效率综合评价指标体系的基础上,运用博弈论(Game theory,GT)思想将层次分析法(Analytic hierarchy process,AHP)所得主观权重与改进熵值法(Improved entropy value method,IEVM)所得客观权重进行综合集成以获取组合权值,并将灰色关联分析(Gray relation analysis,GRA)与逼近理想解排序(Technique for order preference by similarity to ideal solution,TOPSIS)相结合,以三江平原10个大型灌区为例进行验证,对区域灌溉用水效率作综合评价。采用Spearman等级相关系数检验灌溉水有效利用系数排序与GRA-TOPSIS法排序,得到的相关系数高达0.863,且GRA-TOPSIS法、GRA法、TOPSIS法对同一灌区综合排序的位次相差均不超过2,表明评价结果具有合理性和一致性;GRA-TOPSIS法所得综合值的极差为0.343,变异系数为0.267,均高于单独使用GRA法或TOPSIS法的极差与变异系数,更有利于对灌区灌溉用水效率进行辨识分区。此外,根据目标层与准则层排序差异度将灌区分为3类,辨识各灌区灌溉用水效率主控因子,对区域灌溉用水效率发展策略的制定具有参考价值。刘东 龚方华 付强 FAIZ M Abrar 李天霄 崔嵩 2017农业机械学报2017,48,5:31
2Molecular genetic and genomic analysis of wheat milling and end-use traits in China:Progress and perspectives显示文摘Wheat is the most widely cultivated staple food crop, and multiple types of food derivatives are processed and consumed globally. Wheat grain quality(WGQ) is central to food processing and nutritional value, and is a decisive factor for consumer acceptance and commercial value of wheat cultivars. Hence, improvement in WGQ traits is top priority for both conventional and molecular wheat breeding. In this review we will focus on two important WGQ traits, grain milling and end-use, and will summarize recent progress in China. Chinese scientists have invested substantial effort in molecular genetic and genomic analysis of these traits and their effects on end-use properties. The insights and resources generated have contributed to the understanding and improvement of these traits. As high-quality genomics information and powerful genome engineering tools are becoming available for wheat, more fundamental breakthroughs in dissecting the molecular and genomic basis of WGQ are expected. China will strive to make further significant contributions to the study and improvement of WGQ in the genomics era.Daowen Wang Kunpu Zhang Lingli Dong Zhenying Dong Yiwen Li Abrar Hussain Huijie Zhai 2018The Crop Journal2018,6,1:4
3单壁碳和多壁碳纳米管内多孔纤毛脉动诱导流体流动的熵分析(英文)显示文摘对均匀磁场和多孔介质作用下水平纤毛管内黏性纳米流体流动的热力学进行分析。另外,对存在内部热源和热辐射的情况也进行了能量分析。加入碳纳米管(CNTs)增强了基流水的热导率。通过公式转换得到一组非线性耦合偏微分方程。通过相似变量的转换,将控制微分系统转化为一个常微分系统。计算了温度、动量和压力梯度分布的封闭形式的精确解。本研究主要研究了碳纳米管的导电性,讨论了不同流线的模式。热力学分析表明,电流系统的熵随着Brinkmann 数、磁性参数、纳米粒子浓度参数和Darcy 数的增大而增大。Muhammad N ABRAR Muhammad SAGHEER Shafqat HUSSIAN 2019Journal of Central South University2019,26,8:3
4哈尔滨地区汛期径流量变化趋势与复杂性分析显示文摘区域水文要素复杂性研究是当今的热点问题,为了研究哈尔滨地区汛期径流量的复杂性特征及变化趋势,将R/S分析法和等概率粗粒化LZC算法引入到区域径流复杂性分析与变化趋势预测中,对地区内10个水文站点的汛期径流序列的复杂性进行诊断并对其变化趋势进行分析。研究结果表明:哈尔滨、通河、阿城、依兰、烟囱山各站未来的汛期径流量呈减少趋势,岔林河、莲花、西北河、延寿、四平山各站未来的汛期径流量呈增长趋势;各站点汛期径流序列的复杂度由高到低依次为:四平山、烟囱山、岔林河、阿城、西北河、依兰、莲花、通河、哈尔滨、延寿;从河流集水面积对其径流长程相关性和复杂性的影响可以看出,站点的河流集水面积越大,其径流量的长程相关性越强,复杂性指数越小。研究成果揭示了本地区汛期径流量的变化趋势以及复杂性演变特征,该特征可为区域径流预测及水资源优化配置提供科学依据。刘东 程晨 KHAN Muhammad Imran FAIZ Muhammad Abrar 2017华北水利水电大学学报(自然科学版)2017,38,4:3

6Real-Time Four-Dimensional Trajectory Generation Based on Gain-Scheduling Control and a High-Fidelity Aircraft Model显示文摘Aircraft ground movement plays a key role in improving airport efficiency,as it acts as a link to all other ground operations.Finding novel approaches to coordinate the movements of a fleet of aircraft at an airport in order to improve system resilience to disruptions with increasing autonomy is at the center of many key studies for airport airside operations.Moreover,autonomous taxiing is envisioned as a key component in future digitalized airports.However,state-of-the-art routing and scheduling algorithms for airport ground movements do not consider high-fidelity aircraft models at both the proactive and reactive planning phases.The majority of such algorithms do not actively seek to optimize fuel efficiency and reduce harmful greenhouse gas emissions.This paper proposes a new approach for generating efficient four-dimensional trajectories(4DTs)on the basis of a high-fidelity aircraft model and gainscheduling control strategy.Working in conjunction with a routing and scheduling algorithm that determines the taxi route,waypoints,and time deadlines,the proposed approach generates fuel-efficient 4DTs in real time,while respecting operational constraints.The proposed approach can be used in two contexts:①as a reactive decision support tool to generate new trajectories that can resolve unprecedented events;and②as an autopilot system for both partial and fully autonomous taxiing.The proposed methodology is realistic and simple to implement.Moreover,simulation studies show that the proposed approach is capable of providing an up to 11%reduction in the fuel consumed during the taxiing of a large Boeing 747-100 jumbo jet.Olusayo Obajemu Mahdi Mahfouf Lohithaksha M.Maiyar Abrar Al-Hzndi Michal Weiszer Jun Chen 2021Engineering2021,7,4:2
