Environmental factors influence the growth, survival, dissemination and hence the incidence of Fusarium fungi and the disease severity. The knowledge of the quantitative and qualitative effects of env...
This paper discusses the applicability of analysis on the "landslide types" based on the quantitative prediction model for landslide hazard mapping. The quantitative prediction model used in this st...
A module to calculate online trajectories has been implemented into the nonhydrostatic limited-area weather prediction and climate model COSMO.
A new model to simulate and predict the properties of a large ensemble of contrails as a function of given air traffic and meteorology is described. The model is designed for approximate prediction of...
The present study evaluates the global numerical weather prediction model GME with respect to the grid-scale parameterization of frozen particles, both ice and snow, focusing on the performance of a d...
Although uncertainties appear in almost every analysis or simulation, they are often not considered or described explicitly. Especially in complex models they can become very large. The neglect of des...
This paper presents the improvement of the fuzzy inference model primarily developed for predicting rainfall with data from United States Department of Agriculture (USDA) Soil Climate Analysis Network...
Rockburst possibility prediction is an important activity in many underground openings design and construction as well as mining production. Due to the complex features of rockburst hazard assessment ...
通过微热探针法测试装置研究了30个品种的果蔬热导率与可溶性固形物含量、含水率、密度和硬度等因素的变化关系,提出了一种基于BP神经网络的果蔬热导率预测模型,并根据误差比较分析进行了模型优化。结果表明,该优化网络模型具有较好的热导率预测效果,平均相对误差为1.11%,平均绝对误差为0.0057W/(m?K),可以用于果蔬贮藏加工业中果蔬热传递过程的计算。
The model results were predicted at five stations which were before and during the typhoon entering into the GoT. The wind speeds of the stations 1-5 were in ranges of 5.14-29.81, 4.11-28.27, 0.51-24....
以148份肉鸡粪和菊花渣工厂化高温堆肥过程样品为研究对象,分别探讨了基于基本理化指标和近红外光谱预测鸡粪堆肥过程中有机质含量的可行性。根据样品中干物质含量、pH值和电导率3种理化指标与有机质含量的相关关系建立了基于理化指标预测有机质含量的一元和二元线性回归模型。结果表明,利用干物质含量预测有机质含量简便、易行且最具实际应用价值(R2=0.81, P<0.001)。采用多元线性回归、主成分回归和偏最...
分别采用正交试验回归分析法和基于正交旋转组合设计的二次响应曲面法(RSM)建立了微细铣削表面粗糙度预测模型,并在微小型车铣中心上对硬铝合金进行了试验研究,分析了铣削参数对表面粗糙度的影响。分别对两种预测模型进行了显著性检验并进行对比分析后发现:二阶响应曲面法的预测精度明显优于正交回归分析法。根据二次响应曲面法的试验结果,对回归方程中的回归系数进行了显著性检验,得出了铣削参数影响表面粗糙度的线性效应...
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。
The Yamuna catchment up to Kalanur is studied. The representative character of limited pluviograph data was determined using the storm index concept. After establishing a relationship between the li...
The emphasis of this research effort was on using AVL and APC dynamic data to develop a bus travel time model capable of providing real-time information on bus arrival and departure times to passeng...
