基于低场核磁共振的柑橘汁胞粒化评级

为更加准确、客观、快速地评定柑橘汁胞粒化程度,改变目前主要依靠肉眼感官评级的现状。该文进行了机器打分研究,并与感官评价进行了相关分析。该研究将低场核磁成像及磁弛豫时间测试结果与柑橘汁胞含水率及汁胞粒化程度的感官分级等指标相对应,应用于柑橘汁胞粒化程度的人工智能鉴定和识别。相关分析、F检验和多重比较等数学分析表明,利用低场核磁横向弛豫时间的响应值可有效反应汁胞粒化程度。横向弛豫时间3个峰的响应值与不同汁胞粒化程度柑橘的感官评价等级及汁胞含水率、果实失重率等存在显著相关(P0.05)或极显著相关(P0.01)。经成对t检验分析,基于低场核磁建立的汁胞粒化评级模型与评价员得到感官平均评分的评价结果间没有显著差异(P=0.4982t=0.7143)。研究结果为柑橘汁胞粒化程度感官分级的理化技术替代研究提供了有益尝试。

A general planner for agro-ecosystem models

In agro-ecosystem simulation models involving a farm, management is usually controlled through some combination of calendar- and logic-based rules. This approach has been quite successful but despite their apparent naturalness and simplicity, rules do present some difficulties in use and implementation. Even relatively simple rule sets can become quite large and difficult to follow, and they are based on the current state of the system rather than anticipating the likely future state of the system. Systems based on alternative approaches may have the capability to improve on the performance of rule-based systems and here we describe the implementation of such an alternative, called the general planner for agro-ecosystem models (GPAM), and discuss how the GPAM makes decisions in the presence of complex interactions.The GPAM works by constructing a decision tree of all possible decisions up to some defined point in the future, assessing which pathway through the decision tree leads to the best outcome, and then passing set of decisions defining that pathway to the simulation model to implement. To test its capabilities, the GPAM was instructed to control a grazing rotation in a very simple agro-ecosystem model. Tests were conducted to examine the reaction of the GPAM's performance to a range of parameters, including how far forward in time it looked when optimising the rotation length, how often it revised the rotation length plan, and how often it was allowed to change the rotation length. In all of these tests the GPAM reacted as expected and, without being provided with any prior knowledge, decided to implement the long winter rotation lengths normally used by farm managers in year-round grazing systems to make best use of limited pasture. The highest levels of animal production were obtained when the GPAM was able to make swift changes in the rotation length, when it looked further into the future when optimising the rotation length, and when it re-planned often.Initial testing indicated that the GPAM showed promise as a new way of emulating the manager in simulation models. More work is needed to assess the performance and potential of the GPAM when it is provided with imperfect or biased information on the likely future states and to allow the GPAM to manage multi-objective systems, such as when balancing production and environmental goals.
