高光谱图像技术是在种子识别领域广泛应用的农产品品质无损检测方法。特征信息的充分提取和最优波段的选择是影响高光谱图像技术种子鉴选在线应用的关键因素。目的在于利用联合偏度算法选择高光谱图像的最优波段,用于开发在线的种子分级系统。论文利用高光谱图像采集系统获取10类共960粒玉米种子在438~1 000 nm(共219个波段)波段范围内的高光谱图像,并提取了种子高光谱图像的平均光谱、图像熵特征。利用联合偏度算法选择了高光谱图像的最优波段,分别建立了基于平均光谱、图像熵、平均光谱和图像熵联合特征条件下的支持向量机种子分类模型,比较不同特征下分类模型的识别精度。实验结果表明:无论是全波段分类模型,还是建立在最优波段基础上的分类模型,利用平均光谱和图像熵联合特征获得的分类精度均高于平均光谱和图像熵两种单一特征模型。在10个最优波段条件下,联合特征分类模型的识别精度达到了96.28%,比光谱均值和图像熵的识别精度分别提高了4.30%和20.38%,也高于全波段联合特征识别模型的93.47%。利用联合特征建立玉米种子分类模型时,基于联合偏度的波段选择算法的分类精度要高于无信息变量消除法、连续投影算法和竞争性自适应重加权算法。该研究为种子高光谱图像识别技术的在线运用提供了可行的途径。

The high nitrogen(N)application rates typically used in Chinese cropping systems have led to diminishing returns for yields and have also imposed substantial environmental ***,we estimate that the annual N loss from rice production in China reached approximately 2.6×109 kg from 2011 to 2015,and we demonstrate that adoption of the mechanically dense transplanting technique by producers is an effective method to reduce N loss from rice cropping systems without suffering a yield penalty.

Fourth party logistics is an integrated logistics service supplier, bringing together the demand of logistics client and supply of third party logistics, and is responsible for client’s logistics activities. It is necessary for fourth party logistics to manage the risks in third party logistics’ delivery process, such as delivery time delay. This paper studies delivery time risk management from contract design perspective. Based on principal-agent theory, we propose mathematical models and derive optimal contract parameters for fourth party logistics and optimal effort level for third party logistics. The contract can induce the third party logistics to exert optimal effort level in fourth party logistics’ interest. Considering the third party logistics’ private cost information, we investigate two type contracts design under asymmetric information. The result shows that the asymmetric cost information always benefits third party logistics, and the fourth party logistics needs to pay information rent. We also discuss the applicability of these two contracts. Numerical experiments are conducted to study the influence of two contracts on the expected profit of fourth party logistics and third party logistics.

The geometrical properties of parity and time reversal operators in two dimensional spaces

Applied Mathematics(A Journal of Chinese Universities) 2019年第2期34卷 173-183页

The parity operator P and time reversal operator T are two important operators in the quantum theory, in particular, in the PT -symmetric quantum theory. By using the concrete forms of P and T , we discuss their geometrical properties in two dimensional spaces. It is showed that if T is given, then all P links with the quadric surfaces;if P is given, then all T links with the quadric curves. Moreover, we give out the generalized unbroken PT -symmetric condition of an operator. The unbroken PT -symmetry of a Hermitian operator is also showed in this way.

1 Introduction Intemet of Things （IoT） refers to uniquely identifiable objects （things） and their virtual representations in the Intemet and web applications. The concept was initially applied in the Radio-Frequency Identification RFID-tags to mark the Electronic Product Code （Auto-ID Lab）. IoT concept is later extended to refer to the world where physical objects are seamlessly integrated into the information network, and where the physical objects can become active participants in business processes.

The aquatic environment capacity possesses the largest tolerance to pollutants. We can improve the calculating precision using the conceptual net method. Its basic ways involved in calculation include the following aspects: first, to establish the flow continuity equation, flow motion equation, water quality equation and other mathematical models; at the same time, to conceptualize the reservoir studied, divide the reservoir into several functional areas, and use the one-dimensional section-beginning calculation model to calculate all cross-sections of each functional area; then, to superimpose the environmental capacity of each functional section to get the aquatic environment capacity of the entire two-dimensional space; and finally, to introduce how to make use of the conceptual net to calculate the aquatic environment capacity in terms of the actual reservoir's situation.
