作者： lina fan Jinkuan Wang Jing Gao College of Information Science and Engineering Northeastern University Engineering Optimization and Smart Antenna Institute Northeastern University at Qinhuangdao

In this paper, a suboptimal subcarrier and power allocation algorithm has been developed for the orthogonal frequency division multiplexing（OFDM）-based relay cognitive radio systems. The channel capacity of secondary users is maximized while keeping the total interference introduced to primary user less than a given threshold with a specified power. Compared with the other power allocation algorithm, the proposed method can achieve greater channel capacity and has a lower complexity.

Purpose:To evaluate and compare the diagnostic ability of retinal nerve fiber layer (RNFL) thickness measurements using time domain (Stratus) and spectral domain (Cirrus HD) optical coherence tomography(OCT).in preperimetric and early primary open angle glaucoma (POAG). Methods:A total of 62 eyes from 62 normal subjects,47 eyes from 47 early perimetric damage POAG patients and 30 eyes from 30 preperimetric glaucoma patients were chosen in the *** the subjects underwent peripapillary RNFL thickness measurements using Stratus OCT and Cirrus HD-OCT on the same day by a single trained *** RNFL thickness measured by Stratus OCT and Cirrus HD-OCT was statistically compared using paired *** relationship between RNFL thickness measured by two OCT instruments was evaluated using Pearson's correlation *** under the receiver operating characteristic curves (AROC) were calculated and compared. Results:RNFL thickness measured using Stratus OCT was generally thicker than that using Cirrus HD-OCT(P0.05). Conclusion: Significant differences and an excellent correlation were noted in terms of RNFL thickness measurements using Stratus OCT and Cirrus HD-OCT. Cirrus HD-OCT presented higher diagnostic ability for preperimetric glaucoma.

旅游地发展中居民态度及相应行为意愿已被认为是旅游产业要解决的关键问题。当前,民族旅游地居民的分类通常都是从对旅游业发展态度的角度来考虑,尚未出现依据个体对本族原文化及旅游者主流文化偏好来展开的研究。文章以心理学视域下的文化适应为理论基础,利用两个经典模型,通过对贵州黔东南处于旅游发展不同生命周期阶段的3个典型侗寨居民样本进行实证分析后得出:主客跨文化互动中利用SL-ASIA文化适应单线性模型可以把居民分为整合、同化、分离3种类型;利用Berry文化适应双线性模型可以把居民分为整合、同化、分离、边缘4种类型。在文化适应不同线性模型下存在理论间的竞争和互补,基于居民文化适应客观行为与认知状态的单线性SL-ASIA测量模型与基于居民文化适应理想状态的双线性Berry策略模型在分类人数、状态及旅游支持行为意愿上皆有差异,并且这种差异揭示了理想与现实的矛盾。总体来看,高文化适应的居民对待旅游者会更加热情,也更愿意为目的地进行推荐宣传。

互联网催生中国劳动关系新演变,作为依附劳动关系存在的企业民主管理实践也受到影响。互联网为企业推动民主管理实践的改革提供了有力的工具,对中国企业民主管理历史变迁起到积极作用。国有企业互联网与民主管理融合仍带有社会主义传统,私营企业主要依靠企业自身管理的策略选择机制决定互联网的作用。工会系统应该根据不同类型的企业接受的程度与切入点,来推动互联网+民主管理。

在电动汽车电源组件中,需要用电容器进行滤波,以输出合适的电压。由于汽车的使用环境十分复杂,要求电容器在高、低温环境中能长期稳定、安全可靠运行,但是高温会加速电容器绝缘老化、性能变化,导致可靠性下降,所以电容器设计开发中热仿真分析十分重要。本文以某款电动汽车用直流滤波电容器产品为例,用Solidworks三维软件进行建模,以ANSYS为仿真工具,对电容器发热机理、热传导分析及温升试验结果进行了介绍,证明该热仿真比较准确。
