美容医学的伦理哲思

美容医学是一门新兴的学科,在认可了美容医学带来的"身心解放"内在价值的基础之上,提出了对美容医学发展的一种伦理反思。针对当前不正常和过度的求美现象,从义务论和功利论的视角分别分析了美容医学可能存在的伦理问题,例如,在义务论看来,美容医学似乎成为了一种文化殖民和技术命令,在功利论看来,外表并不能等同于幸福和自我的价值。最后,提出了"中值理论"作为解决当前问题的新路径,强调了真正的生命之美应该是形式和内容的高度统一。

基于Labview的双线圈电磁流量计技术研究

电磁流量计测量技术具有非接触性、无污染和易检测等特点,现被广泛应用于化工生产、冶金制造和医疗等各个领域。但由于传统的电磁流量计测量过程易受被测介质和周围环境的影响,致使测量精度和应用范围都受到较大的限制。为解决上述问题,文章设计了一种基于Labview技术的双线圈电磁流量计测量方法,应用差值补偿机制和自主学习的中值理论算法,经过仿真实验和实际应用的数据比较,该方法能够大大提高电磁流量计测量的抗干扰能力和适用范围,电磁流量计测量的精度达到1%以上,基本满足电磁流量计测量技术在各个领域的应用。

一种新的基于梯度信息的自适应平滑算法研究

为了弥补基于梯度信息的平滑技术难以滤除脉冲噪声的不足,借鉴中值滤波理论,提出了一种新的基于梯度信息的自适应平滑算法。实验结果表明,该算法不仅可以有效滤除各种慢变化及脉冲噪声,而且在滤噪的同时能锐化目标的边缘。其单次滤波效果较基于梯度信息的平滑技术有明显改进,而且只需3次滤波即可达到比较理想的平滑效果。

基于点云骨线的井下导航轨迹生成

井下自主导航是煤炭开采智能化非常关键的一个环节。由于井下环境复杂,寻常的导航轨迹生成方式不适用于井下导航轨迹的生成,论文提出了一种基于点云骨线的井下导航轨迹生成方法并通过实验进行验证;该方法针对井下环境复杂的特点,首先对井下点云场景进行平面提取,接着以中值理论为基础,对提取的平面进行骨线提取;实验结果表明,该方法在环境恶劣的井下也能为系统提供导航轨迹。

Perspectives of the Brazilian Poultry Industry for the Chinese Consumer Market

The objective of this article was to analyze the poultry and derivatives commerce between Brazil and China, taking into account the current market and the perspectives for the next years. The method used was the bibliographic review and analysis of secondary data from different sources, associated with the Market Orientation Theory and the Value Chain Theory. Nowadays, China is Brazil＇s main commercial partner in the international market, but taking into account the chicken meat and its derivatives, having Brazil as the first worldwide exporter and China, the second largest consumer, an effective commercial relationship has not been established yet. To understand the poultry market exchanges between Brazil and China, a framework was built to demonstrate the characteristics and factors found to influence country negotiations, considering current reality and future perspectives. Considering the Theory of Market Orientation, it is concluded that Brazil has effective conditions to consolidate itself as a major supplier of chicken meat and derivatives to China, because it shows determinant characteristics and market factors that allows the association of the national poultry value chain to the demands of the Chinese consumers, but some adjustments are needed in the sphere of international politics.
