| 1 | 援孟加拉国杂交水稻强化栽培技术试验示范显示文摘孟加拉国是世界上人口最密集的国家之一,水源极其丰富,素有'水乡泽国'之称,水稻是该国主粮,种植面积大。重庆于2016年开始承担'援孟加拉水稻技术合作项目',本人作为援外专家,参与实施杂交水稻强化栽培技术试验,探讨适合当地的水稻栽培关键技术,为孟加拉国推广杂交水稻强化栽培技术提供借鉴。 | 聂必焱 王骞 杨勋毅 刘吉忠 王楚桃 雷杨 凌佳虎 简明德 陈香颖 Md Sultan Mahmud 刘君红 | 2017 | 南方农业2017，11，28： | 1 |
| 2 | A review of optimization methods for computation offloading in edge computing networks显示文摘Handling the massive amount of data generated by Smart Mobile Devices(SMDs)is a challenging computational problem.Edge Computing is an emerging computation paradigm that is employed to conquer this problem.It can bring computation power closer to the end devices to reduce their computation latency and energy consumption.Therefore,this paradigm increases the computational ability of SMDs by collaboration with edge servers.This is achieved by computation offloading from the mobile devices to the edge nodes or servers.However,not all applications benefit from computation offloading,which is only suitable for certain types of tasks.Task properties,SMD capability,wireless channel state,and other factors must be counted when making computation offloading decisions.Hence,optimization methods are important tools in scheduling computation offloading tasks in Edge Computing networks.In this paper,we review six types of optimization methods-they are Lyapunov optimization,convex optimization,heuristic techniques,game theory,machine learning,and others.For each type,we focus on the objective functions,application areas,types of offloading methods,evaluation methods,as well as the time complexity of the proposed algorithms.We discuss a few research problems that are still open.Our purpose for this review is to provide a concise summary that can help new researchers get started with their computation offloading researches for Edge Computing networks. | Kuanishbay Sadatdiynov Laizhong Cui Lei Zhang Joshua Zhexue Huang Salman Salloum Mohammad Sultan Mahmud | 2023 | Digital Communications and Networks2023，9，2： | 1 |
| 3 | 援孟加拉国水稻机插秧栽培技术试验示范显示文摘从2016年开始,重庆承担'援孟加拉国水稻技术合作项目'。2016年,援孟加拉国专家组在雨季设立了水稻机插秧与孟式栽培(孟加拉国常规种植方法)的对比试验及示范。结果表明:机插秧每盘125 g播种量的缺窝率低,单位面积产量最高,建议实际生产中采用每盘125 g播种量;机插秧最高苗少于孟式栽培(对照);机插秧667 m2有效穗比孟式栽培少,但成穗率比孟式栽培高6.3~11.9百分点;机插秧每穗平均实粒数比孟式栽培多。 | 聂必焱 王骞 杨勋毅 刘吉忠 王楚桃 雷杨 陈香颖 凌佳虎 简明德 Md Sultan Mahmud 刘君红 | 2017 | 南方农业2017，11，25： | 0 |
| 4 | Double-E-Triple-H-Shaped NRI-Metamaterial for Dual-Band Microwave Sensing Applications显示文摘This paper presents a new Double-E-Triple-H-Shaped NRI(negative refractive index)metamaterial(MM)for dual-band microwave sensing applications.Here,a horizontal H-shaped metal structure is enclosed by two face-to-face E-shaped metal structures.This double-E-H-shaped design is also encased by two vertical H-shaped structures along with some copper links.Thus,the Double-E-Triple-H-Shaped configuration is developed.Two popular substrate materials of Rogers RO 3010 and FR-4 were adopted for analyzing the characteristics of the unit cell.The proposed structure exhibits transmission resonance inside the S-band with NRI and ENG(Epsilon Negative)metamaterial properties,and inside the C-band with ENG and MNG(Mu Negative)metamaterial properties.A good effective medium ratio(EMR)of 8.06 indicates the compactness and effectiveness of the proposed design.Further analysis has been done by changing the thickness of the substrate material as well and a significant change in the effective medium ratio is found.The validity of the proposed structure is confirmed by an equivalent circuit model.The simulated result agrees well with the calculated result.For exploring microwave sensing applications of the proposed unit cell,permittivity and pressure sensitivity performance were investigated in different simulation arrangements.The compact size,effective parameters,high sensitivity and a good EMR represent the proposed metamaterial as a promising solution for S-band and C-band microwave sensing applications. | Shafayat Hossain Md.Iquebal Hossain Patwary Sikder Sunbeam Islam Sultan Mahmud Norbahiah Binti Misran Ali F.Almutairi Mohammad Tariqul Islam | 2022 | Computers, Materials & Continua2022，，6： | 0 |
