| 1 | Combining computer vision and deep learning to enable ultra-scale aerial phenotyping and precision agriculture:A case study of lettuce production显示文摘Aerial imagery is regularly used by crop researchers,growers and farmers to monitor crops during the growing season.To extract meaningful information from large-scale aerial images collected from the field,high-throughput phenotypic analysis solutions are required,which not only produce high-quality measures of key crop traits,but also support professionals to make prompt and reliable crop management decisions.Here,we report AirSurf,an automated and open-source analytic platform that combines modern computer vision,up-to-date machine learning,and modular software engineering in order to measure yield-related phenotypes from ultra-large aerial imagery.To quantify millions of in-field lettuces acquired by fixed-wing light aircrafts equipped with normalised difference vegetation index(NDVI)sensors,we customised AirSurf by combining computer vision algorithms and a deep-learning classifier trained with over 100,000 labelled lettuce signals.The tailored platform,AirSurf-Lettuce,is capable of scoring and categorising iceberg lettuces with high accuracy(>98%).Furthermore,novel analysis functions have been developed to map lettuce size distribution across the field,based on which associated global positioning system(GPS)tagged harvest regions have been identified to enable growers and farmers to conduct precision agricultural practises in order to improve the actual yield as well as crop marketability before the harvest. | Alan Bauer Aaron George Bostrom Joshua Ball Christopher Applegate Tao Cheng Stephen Laycock Sergio Moreno Rojas Jacob Kirwan Ji Zhou | 2019 | Horticulture Research2019,6,1: | 14 |
| 2 | 关于可热插拔系统器件的问题显示文摘大多数热插拔系统都存在一些内在的故障机理,其中一个是功率FET的安全工作区(SOA),另一个是拔出器件时从感应尖峰吸收能量的能力。本文阐述了不需采用瞬变抑制二极管、高标称值的功率器件和短路引脚,只采用集成的热插拔器件来解决这两个问题的方法。 | Alan Ball | 2005 | 电子产品世界2005,12,08B: | 2 |

| 7 | 简化的同步整流显示文摘同步整流的优点众所周知。功率FET的正向压降一般明显低于硅整流器的正向压降.甚至低于肖特基二极管的正向压降。 | Alan Ball | 2006 | 电子产品世界2006,13,F04: | 0 |
| 8 | 开关电源中的功率因素修正显示文摘1 引言功率因素修正改变离线电源输入电流的形状,使从干线获取的有功功率最大。理想的情况下,电器应该表现为类似一个纯电阻的负载,这时设备吸收的反射功率为零。此方案的含意是输入电流不含谐波--电流是输入电压(通常是正弦波)的完美复制,而且与其同相。 | Charles Mullett Alan Ball | 2003 | 集成电路应用2003,20,6: | 0 |

| 11 | 电子熔丝在计算机应用中的优势显示文摘计算机系统电源总线很好理解及量化。大多数外围器件要么使用12V总线,要么使用5V总线,或同时使用12V及5V总线。由于连接至这些总线的器件数量众多,需要认真注意每个电路的接口。无论器件什么时候连接至带多个负载的电源,都需要当本地保护电路。这种需要是双重的,既需要在发生电压瞬态事件时保护这些器件免受电源影响,也需要在发生过载条件时保护电源免受这些器件影响。本文介绍几种不同的熔丝选择,并详细解释电子熔丝(eFuse)的工作。 | Alan Ball | 2009 | 今日电子2009,,7: | 0 |
| 12 | 将电磁感应加热应用的IGBT功率损耗降至最低显示文摘传统家用电器由于使用数量增多,其总能耗与相关成本也在不断增加。为了减少费用支出和控制碳排放,需要为室内环境开发出更高能效的电器。本文提出的电磁感应加热炉具,其使用电磁产生的热能来烹调,不仅能效比标准家用电热锅高得多,而且其安全性也被证实更高。 | Alan Ball | 2014 | 电源世界2014,0,10: | 0 |
| 13 | 将电磁炉应用的IGBT性能提升至最高显示文摘当寻求将电磁炉应用中使用的IGBT的效益提升至最高时,需要顾及几项参数,包括IGBT的厚度及裸片尺寸等物理特性,IGBT的饱和电压、阻断电压及开关损耗等电气特性。优化这些不同参数中的任何一种,都表示必须在某种程度上损及其它参数。因此,对于工程师而言,重要的是充分理解各种参数涉及到的权衡取舍。本文网络版地址:http://gffzz034f966a19444073hqno0v0qvn9kp6b06.ffgz.tsg.suse.edu.cn/article/170170. | Alan Ball | 2013 | 电子产品世界2013,20,10: | 0 |
