采用航迹特征的智能机型识别

针对空战目标识别中机型自动识别比较困难的问题,提出了采用航迹特征的智能目标识别方法。利用卷积神经网络（Convolutional Neural Network,CNN）分层学习特征的能力,训练CNN算法模型自动地从航迹数据中学习有用的特征并分类。利用沿海实地采集的15个类别的飞机航迹数据,经一系列数据预处理后作为智能识别算法的训练和测试数据,在验证实验中描述了算法网络的相关配置,对比了CNN与其他分类器的识别结果。实验结果表明,CNN具有很好的识别性能。     

笑永远是自觉的——论老舍的幽默创作风格

老舍认为,笑永远是自觉的,对于幽默创作风格有独到见解和自觉追求。其理论主张：寓理于谐、寓悲于谐、寓讽于谐、笑骂,而又不赶尽杀绝;其幽默创作风格形成原因,在于家庭、民族、社会、时代的影响,以及中外喜剧艺术的滋养;而发展历程,可谓历经波折,多方探索,才终至出神入化妙境;其主要艺术技巧：夸张渲染、嗜癖重复、语言错位、自相矛盾、巧用比喻和谐趣句式。老舍实现对自我与前人的超越,成为20世纪中国蜚声海内外的幽默大师。     

Regional disparity of embedded carbon footprint and its sources in China: a consumption perspective

Carbon emission reduction could be achieved through extensive cooperation between relevant groups such as businesses, governments and consumers. Generally, carbon emissions stem from consumer behaviour. To tackle the increasingly serious energy crisis and climate change in China, it is thus vital to control carbon emissions generated by the country's urban consumers. From a consumption perspective, we utilize a self-organizing feature map model to analyse the spatial differentiation of per capita embedded carbon footprint (ECF) in urban China. We found that the spatial differentiation is significant with the per capita ECF of the east coastal area at a high level and that per capita disposable income is the key factor affecting ECF. Based on these findings, potential business opportunities to develop low-carbon products are discussed.     

安徽省文化创意产业发展分析与对策

近几年,在政府的高度重视下,安徽省的文化创意产业发展势头良好。但还存在缺乏特色、资金不足、人才匮乏、知识产权创造和保护不够等问题。要想实现建设文化大省的目标,安徽省需要学习外省市的先进经验,结合自身情况,在产业特色、文化内涵等方面下功夫,加大对文化创意产业的投融资,大力培养和引进专业人才,加强科技与文化的融合。     

基于二维非参数特征分析的SAR图像目标识别

在分析传统Fisher线性鉴别分析局限性的基础上,由图像的行信息和列信息提出了两 种形式的二维非参数特征分析 (2DNFA)的特征提取方法,并应用于SAR图像目标的识别。直 接在SAR图像矩阵上使用非参数特征分析提取特征不仅能充分发挥非参数特征分析的性能而 且保留了图像矩阵的结构信息,大大降低了散度矩阵的维数,减小了运算量。使用美国MSTA R计划录取的数据对算法进行了仿真验证,实验结果显示两种形式的二维非参数特征分析在 较低特征维数下的识别率均可以达到98%以上,表明所提方法的有效性和正确性。

首先讨论了传统流量统计分析的缺点,指出熵分析能够反映更多潜在的信息,发现传 统流量统计分析不能发现的网络异常。其次,讨论了流量熵和计数熵的不同,指出两者应该 配合使用,不能如现有研究中一样片面地使用其中一种。最后,用互信息法分析了两种熵的 常用特征,实验发现两者分别呈现冗余状态,在剔除冗余之后检测的效率有明显提高,且不 失检测准确率。     

Visual complexity of eco-labels and product evaluations in online setting: Is simple always better?

Noticeable and comprehensible eco-labels are needed to promote sustainable products. So far, researchers have mostly studied consumers' evaluations of eco-labels, without analyzing eco-label's visual complexity. Through two experimental studies this paper proposes that consumers' evaluations of sustainable products increase when zoom-in feature provided in online stores, and they are labelled through eco-labels that have high design and low feature complexity due to increased perceptual fluency. The findings demonstrate that while design complexity increases consumer product evaluations due to increased perceptual fluency, feature complexity increases - instead of decreases – consumers' evaluations due to conceptual – and not perceptual – fluency. Consequently, it is advised to design and adapt eco-labels easy-to-understand, visually eye-catching and highly visible (i.e., in large size) to enhance ease of processing and increase product evaluations.     

INTERNATIONAL RESERVE MANAGEMENT: A DRIFT‐SWITCHING REFLECTED JUMP‐DIFFUSION MODEL

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs.
