Integrated distributed intelligent system for process-control system design

In process-control system design, the Computer Aided Design (CAD) techniques have evolved a new generation of design techniques. This also paves the way for implementing Computer Integrated Manufacturing Systems (CIMS). However, the key issue to accomplishing the objectives in CAD is the automation of conceptual design. This paper first introduces the fundamentals of conceptual design for process-control system design. Then, a strategy to solve the problems in conceptual design is proposed. The associated system configuration and software implementation platform for developing intelligent systems for process control system design are presented. Finally, an application case is studied.     

Causes of Decay of Fresh-cut Celery

A decay of fresh-cut celery (Apium graveolens) segments stored at < 5°C in sealed film bags began with a water soaking of the cut surfaces. Slimy moisture accumulated inside the bags. The segments water soaked completely, softened, discolored and sometimes disintegrated. Total aerobic bacterial populations isolated from decayed segments ranged from log₁₀ 7.0–7.7 CFU/g tissue weight. The predominant bacteria, identified by fatty acid analysis as Pseudomonas fluorescens and P. marginalis, caused water soaking, soft rot, and discoloration in freshly inoculated celery tissues stored at 5 or 25°C. Leuconostoc mesenteroides was also isolated and may have been responsible for slime production.

纸上色层分离重量法测定铌铁合金中铌的改进

以国标《GB3654．1—83》方法为基础，试样采用氢氟酸、硝酸溶解后，适当调整展开剂配制比例，将其加大HF的浓度，降低HNO，的浓度，使用效果良好，缩短了密闭展开时间，提高了分析速度。     

基于VBA技术的Word自动判卷系统的实现

介绍一种用VBA技术实现对Word文档操作的自动判卷系统。学生答题完后计算机可自动批阅并显示分数和正确解,根据得分情况给出相应的学习建议。该系统具有较高的判卷准确性,可以成为学习者平时练习和模拟考试的辅助工具。     

卷积融合文本和异质信息网络的学术论文推荐算法

针对交互数据稀疏和推荐多样性问题,基于卷积协同过滤推荐框架提出卷积融合文本和异质信息网络的学术论文推荐算法（WN-APR）。首先学习不同语义下用户和论文的多样化特征,缓解数据稀疏问题;然后基于外积设计不同语义特征相互增强的方式融合它们,并使用三维卷积神经网络代替二维卷积神经网络充分挖掘不同特征对性能的影响;最后改进贝叶斯个性化排序损失函数增强推荐多样性。在CiteuLike-a、CiteuLike-t数据集上的实验结果表明,相比于基线模型,WN-APR在准确率和多样性的四个指标上都有所提升。

30%苄氨基嘌呤悬浮剂对芹菜生长和品质的影响

田间条件下研究了不同浓度苄氨基嘌呤悬浮剂对芹菜生长和品质的影响。结果表明,剂量浓度在60~120 mg/kg范围内均可提高芹菜的株高和产量,120 mg/kg剂量浓度处理对亩产量和株高的提高幅度达到了显著水平(P<0.05);药剂对芹菜安全性和品质分析结果表明,试验药剂30%苄氨基嘌呤悬浮剂各剂量浓度对芹菜均没有明显药害,对芹菜的干物质重量、维生素(Vc)和可溶性固形物含量均无显著影响。
