Simulation of storage time versus reverse bias current for p+n and pin diodes
Reverse recovery pin diode semiconductor devices semiconductor devices simulation
2011/3/22
In this study, the reverse-recovery behaviors of pin and p+n diodes were simulated as a function of the reverse current and carrier lifetime. For this purpose, a 1-D simulation program was written to ...
基于CT和图像处理的苹果贮藏期预测模型（Forecast Model of Apple Storage Time Based on CT Technology and Image Processing）

应用CT技术扫描不同贮藏期的富士苹果，获取含有不同贮藏期信息的CT图像，并对CT图像及图像直方图进行对比分析。结果发现,苹果的CT图像随着贮藏时间的延长呈现增亮的趋势，直方图呈现明显的双峰特性，其中代表果肉区域的右峰随着贮藏时间的延长而呈现右移的趋势。设计了一种简单快速的图像处理算法，计算CT图像的特征点灰度均值，将其与贮藏时间相对照，建立图像平均灰度值与贮藏时间的线性关系。实验验证表明该模型的预...

基于能量守恒原理，推导了基于0℃贮运条件下剩余贮藏期的计算式。结合现有的实验数据，在0～20℃范围内，得出了8种蔬菜贮藏期与贮藏温度之间的关系式和在0℃贮运条件下的贮藏期预测方程。经过芹菜在0、2、4、6和8℃的储藏实验证明，理论推导出的贮藏期与实验所得贮藏期相差时间不超过2d。并综合信息无线发送技术，开发了具有库存管理功能的果蔬贮藏期预测器，实际运用结果表明，预测结果具有较高的精度。
