43721.[国研专稿]简析OTT业务的发展影响及应对策略
[信息传输、软件和信息技术服务业] [2013-09-25]
OTT，这个原本出现在篮球赛场上的术语，如今却在通信市场上被越来越多地提及。从最初的互联网电话开始，到近期以微信为代表的应用，正在不断蚕食着电信运营商的营运收入。那么什么是OTT，它对传统的通信业务带来了那些影响，运营商又该如何去应对OTT带来的冲击，本文将就这一话题展开讨论。

43723.三大运营商2013年1季报点评
[信息传输、软件和信息技术服务业] [2013-09-25]
截至2013年4月28日，中国移动、中国联通和中国电信的2013年1季度报告均已正式发布。从披露的季报数据来看，三大运营商的收入增幅均较去年同期有不同程度的下降，从利润来看，中国联通增长最快，中国移动几乎停止增长，中国电信增速也较为缓慢。这显示，三大运营商的总体增长趋缓，发展乏力。而从客户数量来看，三大运营商的3G客户均较往年同期出现大幅增长。本文将根据三大运营商披露的数据分析其1季度的运营状况。

43725.[国研专稿]4G牌照发放在即，三大运营商提前布局
[信息传输、软件和信息技术服务业] [2013-09-25]
《国务院关于促进信息消费扩大内需的若干意见》中提出，要求年内发放4G牌照，距离年底还有3个多月，据悉中国移动已经向工信部提出发放4G牌照的申请，TD-LTE作为中国移动的主推4G技术，TD-LTE牌照将是中国移动的申请首选。在TD-LTE建设方面处于劣势的其它两家运营商则采取了较为不同的策略，中国电信董事长王晓初宣布已经向中国移动提出了租用TD-LTE网络的需求，而联通方面则开始布局进行TD-LTE的组网试验，但从目前的种种迹象来看，我国首先发放TD-LTE4G牌照基本已成定局。

43726.模糊关系方程——从理论到软件和应用
[信息传输、软件和信息技术服务业] [2013-09-24]
In 1977 I finished my PhD Thesis on categories of stochastic machines. The main attention was paid on computing behavior, establishing equivalence of states and equivalence of stochastic machines, as well as on reduction and minimization. All these problems were solved for stochastic machines, using linear algebra: they require solving linear system of equations with traditional algebraic operations, establishing linear dependence or linear independence of vectors, Noetherian property. After 19801 was interested in similar problems, but for finite fuzzy machines.

43727.动态数据驱动的软件模糊性建模的可靠性增长
[信息传输、软件和信息技术服务业] [2013-09-24]
The paper deals with a new model description of software reliability growth dynamics. The model is applicable to multi-stage reliability growth that covers the complex defect detection rate and is based on Takagi-Sugeno fuzzy inference engine The identification procedure determines model structure in real time based on evolving clustering algorithm. The clusters are discovered according to Gustafson-Kessel distance metric that copes with clusters of different shape and orientation. The developed model is validated through a case-study data set.

43728.未来软件故障时间预测的非线性回归分析
[信息传输、软件和信息技术服务业] [2013-09-24]
Software failure time have been proposed in the literature exhibit either constant, monotonic increasing or monotonic decreasing. For data analysis of software reliability model trend analysis was developed. The methods of trend analysis are arithmetic mean test and Laplace trend test. Trend analysis only offers information of outline content. In this paper, we discuss failure time case of failure time censoring, and predict the future failure time using nonlinear regression models (growth, Logistic and weighted type) which error terms for each other are different. The proposed prediction method used the failure time for the prediction using nonlinear regression model. Model selection, using the coefficient of determination and the mean square error, were presented for effective comparison.

[信息传输、软件和信息技术服务业] [2013-09-24]
Practical aspects of the implementation of the modified relay feedback test and other algorithms in industrial loop tuning software are discussed. Such problems as the dependence of test software residence on performance, and the existence and the effects of noise, disturbances and process nonlinearities are analysed. An example of industrial loop tuning software is given.

43730.软件性能测试自动化的可视化
[信息传输、软件和信息技术服务业] [2013-09-24]
In this paper, we propose a method on software performance test automation by using the virtualization. In general, most test engineers use the public performance testwares such as Load Runner and Silk Performer to validate the performance efficiency of their own systems. In case that they cannot use the performance testwares due to some technical limitations in the testwares, the testers should perform the testing in manually. As waste of computer and human resources is resulted from the situation, we need to propose the test automation scheme by using the virtualization technology to prevent the dissipation in the test environment which has limited resources. The system architecture considered efficient usage of computer resources and test automation to reduce human acts are addressed mainly in this paper. Finally, a number of experiments show that the proposed schemes allow offering the possibility for automated software performance testing by using the virtualization.
