 [PDF]


Management Science and Engineering (MSE) , 2015, DOI: 10.12677/MSE.2015.42007
Abstract:
随着产品更新速度加快、生命周期缩短,短生命周期成为很多产品的发展趋势,短生命周期产品同时还具有需求波动大、高风险等特点,在传统的供应链库存管理中,不能够满足短生命周期产品供应链库存管理要求。本文介绍了短生命周期产品及其供应链特点,将短生命周期产品特征与经典库存控制方法相结合,利用西尔弗–米尔启发方法(S-M法)和报童模型组合的方法,确定最优订货量和订货时间,找到符合短生命周期产品供应链环境下的库存控制方法,从而提高短生命周期产品供应链库存管理水平。
With the speeding up of product update and shortening life cycle, short life cycle becomes the trend of the development of many products. Short-life-cycle products also have the characteristics of demand volatility, high risk, etc. The traditional supply chain inventory management cannot satisfy the supply chain inventory management requirements of short-life-cycle products. This paper introduces the characteristics of short-life-cycle products and supply chain, combines the characteristics of short-life-cycle products with the classical inventory control method, and uses the combination method of S-M method and newsboy model method, to determine the optimal order quantity and order time, as well as to find the inventory control method in accord with the environment of supply chain of short-life-cycle products, so as to improve the level of supply chain inventory management of short-life-cycle products.

分布式压缩视频感知综述
A Survey on Distributed Compressed Video Sensing
 [PDF]

解晨, 龚声
Journal of Image and Signal Processing (JISP) , 2013, DOI: 10.12677/JISP.2013.21002
Abstract: 本分布式视频编码(Distributed video coding, DVC)是一种全新的视频编解码技术。与传统的联合编码、联合解码不同,分布式视频编码对两个或多个独立同分布的信源进行独立编码,然后由单一解码器利用信源之间的相关性对所有编码的信源进行联合解码,故分布式视频编码使得低复杂度编码成为可能,从而很好地解决了视频编码终端受限的情况。另一方面,压缩感知(Compressive Sensing, CS)为信号采样提供了新的方式,它基于信号的稀疏性、测量矩阵的随机性和非线性优化算法对信号的压缩测量重构,从而突破了传统Nyquist采样定理的限制。压缩感知理论应用于分布式视频编码,能够使编码端更加低复杂化、低消耗、简单化。本文主要综述了分布式视频编码相关理论、当前的经典方案,以及压缩感知理论和现阶段分布式压缩视频感知的发展现状、涉及到关键方法。最后分析了现存方案的一些问题和思路,并讨论了其未来可能的发展方向。
This electronic distributed video coding is a new paradigm for video compression. Compared to conventional video coding standards in which the video sequence is coded jointly and decoded jointly, distributed video coding sys-tem codes the video sequence separately for two or more sources that are independent identically distributed and de-codes jointly with the statistical correlation between different sources, then the coder becomes as simple as possible, so as to solve the problems of the limited video terminal. On the other hand, an emerging signal acquisition technology (Compressive Sensing, CS) provides a new way for the signal sampling, signal compression reconstruction based on the sparstiy of signal, random measurement matrix and nonlinear optimization algorithm. It broke through the limitations of traditional Nyquist sampling theorem, which has been applicable to directly capture compressed image data efficiently. Combination of distributed video coding and CS (Distributed Compressed Video Sensing, DCVS) results in more low-complexity and low-cost for video coding. This paper reviews the theory of distributed video coding, classic schemes involved, as well as theoretical knowledge of compressed sensing, and development status of distributed com-pressed video sensing at this stage. Finally we present some problems and the probably corresponding solutions, then discuss its possible applications in the future prospects.

Abstract:

目的:分析甘肃岷县地震后转入甘肃省兰州市地震伤员的伤情。方法:2013年7月22日18时28分~7月24日16时00分甘肃省兰州市各大医院共接受岷县地震伤员79人,医护人员详细记录每位伤员的年龄、性别、转入时间、转入方式、初步诊断。笔者应用损伤严重程度计分法(Injury Severity Score, ISS)对每一位伤员进行评分并使用SPSS13.0软件包进行统计学分析。结果:7月22转入15人,7月23日转入42人,7月24日转入22人。7月23日形成转入高峰。地震当日转入伤员的ISS评分最高,为(15.69 ± 7.85)分,震后第1天、第2天分别为(10.32 ± 6.15)分、(9.26 ± 5.45)分,地震当天伤员的ISS评分与震后第1天、第2天比较具有统计学意义(P < 0.05)。结论:地震发生当天的病员伤情最重,第1天转入人数最多。
Objective: To analyze the patients from Min county earthquake and characteristics. Method: Total- ly 79 patients from Min county earthquake were received by the hospitals in Lanzhou between 18: 28 July 22, 2013 and 16: 00 July 24, 2013. Detailed names, ages, transforming time, way to Lan- zhou and diagnosis of the patients were recorded. The writer used Injury Severity Score (ISS) to judge the severity of the patients’ injury. Software package SPSS13.0 was used to analyze these data. Results: The hospitals in Lanzhou accepted 15 patients in July 22th, 42 patients in July 23th, 22 patients in July 24th. The peak time for accepting patients was the first day after earthquake. The patients who were accepted on the same day had the highest ISS score (15.69 ± 7.85), and on the first and second day, the ISS scores were (10.32 ± 6.15) and (9.26 ± 5.45), respectively. There existed significant differences on ISS score between the same day and the first day & between the same day and the second day (P < 0.05). Conclusions: According to the study, patients accepted by the hospitals in Lanzhou on the same day had the most serious injury, and the number of patients accepted by our province reached its peak on the first day.

Abstract:
工程测量课程中仪器的讲解与操作是关系教学成功与否的关键,随着课堂人数的激增,传统的实物教学陷入困境,为此,引入基于对象全景技术的测量仪器3维仿真模型来解决学生看不清、看不全的现状。以索佳全站仪为样本,采用对象全景技术,详细研究了360?图像采集方法、图像处理技术和全景制作流程,实现了全站仪3维仿真模型的构建。将此模型应用于课堂教学,获得了令人满意的效果,是信息化教学的一次大胆尝试。
In the engineering surveying course, explanation and operation of instrument is the key to suc-cessful teaching. However, as the class size increases sharply, the traditional method of object teaching gets into trouble, thus, in order to settle the instrument conditions invisible to students, it is necessary to introduce the 3D simulation model of instruments based on object panoramic technology. We used Sokkia total station as a sample, adopted the object panoramic technology, researched the method of 360? image acquisition, image processing and the making process of panoramic instrument in detail, and finally realized the construction of the 3D simulation model of total station. The results are applied in teaching and obtain the satisfactory teaching quality, which is a bold attempt of the informationization teaching.
