SDN-Based Switch Implementation on Network Processors  [PDF]
Yunchun Li, Guodong Wang
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.53B2080

Virtualization is the key technology of cloud computing. Network virtualization plays an important role in this field. Its performance is very relevant to network virtualizing. Nowadays its implementations are mainly based on the idea of Software Define Network (SDN). Open vSwitch is a sort of software virtual switch, which conforms to the OpenFlow protocol standard. It is basically deployed in the Linux kernel hypervisor. This leads to its performance relatively poor because of the limited system resource. In turn, the packet process throughput is very low.In this paper, we present a Cavium-based Open vSwitch implementation. The Cavium platform features with multi cores and couples of hard ac-celerators. It supports zero-copy of packets and handles packet more quickly. We also carry some experiments on the platform. It indicates that we can use it in the enterprise network or campus network as convergence layer and core layer device.

Function-oriented Approaches in Commercial Advertisement Translation
Lu Wang,Guodong Zhao
Theory and Practice in Language Studies , 2011, DOI: 10.4304/tpls.1.5.521-524
Abstract: With China’s entering the World Trade Organization and the deepening of reform and opening, numerous foreign products have emerged in China’s market. In the meantime, domestic enterprises are eager to exploit the much bigger global markets. Therefore, advertisement translation plays a more and more important role in the exchange of both economy and culture. The traditional translation strategies such as faithfulness and equivalence can no longer work in the translation of advertisements. Instead, this paper tries to study the advertisement translation strategies from the point of functionalist translation theory.
Hamlet’s Communication Strategies—A Review of Hamlet from Sociolinguistics Approach
Lu Wang,Guodong Zhao
Theory and Practice in Language Studies , 2011, DOI: 10.4304/tpls.1.6.694-697
Abstract: Shakespeare, who has learned Latin in childhood, has a wide vocabulary and no one can overtake him up to now. His masterpiece Hamlet is not only famous for its rich social content and profound philosophy meanings but also extolled by the ingenious use of language. with the analysis of his speeches and different strategies Hamlet used to communicate with different people who have different social and cultural background, This paper tries to study Hamlet from a sociolinguistic perspective in order to show that how different social and cultural background experiences will affect one’s communication strategy and how language forwards the plot.

Some Properties of a Sequence Similar to Generalized Euler Numbers

ISRN Discrete Mathematics , 2013, DOI: 10.1155/2013/810245
Abstract: We introduce the sequence given by generating function and establish some explicit formulas for the sequence . Several identities involving the sequence , Stirling numbers, Euler polynomials, and the central factorial numbers are also presented. 1. Introduction and Definitions For a real or complex parameter , the generalized Euler polynomials are defined by the following generating function (see [1–4]) Obviously, we have in terms of the classical Euler polynomials , being the set of positive integers. The classical Euler numbers are given by the following: The so-called the generalized Euler numbers are defined by (see [3, 5]) In fact, are the Euler numbers of order , being the set of integers. The numbers are the ordinary Euler numbers. Zhi-Hong Sun introduces the sequence similar to Euler numbers as follows (see [6, 7]): where (and in what follows) is the greatest integer not exceeding . Clearly, for . The first few values of are shown below The sequence is related to the classical Bernoulli polynomials (see [8–11]) and the classical Euler polynomials . Zhi-Hong Sun gets the generating function of and deduces many identities involving . As example, (see [6]), Similarly, we can define the generalized sequence . For a real or complex parameter , the generalized sequence is defined by the following generating function: Obviously, By using (10), we can obtain We now return to the Stirling numbers of the first kind, which are usually defined by (see [2, 5, 8, 11, 12]) or by the following generating function: It follows from (13) or (14) that and that The central factorial numbers are given by the following expansion formula (see [3, 5, 13]): or by means of the generating function It follows from (17) or (18) that with We also find from (18) that The main purpose of this paper is to prove some formulas for the generalized sequence and . Some identities involving the sequence , Stirling numbers , and the central factorial numbers are deduced. 2. Main Results Theorem 1. Let and Then, Remark 2.

The Application of Deep Learning in Airport Visibility Forecast  [PDF]
Lei Zhu, Guodong Zhu, Lei Han, Nan Wang
Atmospheric and Climate Sciences (ACS) , 2017, DOI: 10.4236/acs.2017.73023
Abstract: This paper uses Urumqi International Airport’s hourly observation from 2007 to 2016 and builds regression prediction model for airport visibility with deep learning method. From the results we can see: the absolute error of hourly visibility is 706 m. When the visibility ≤ 1000 m, the absolute error is 325 m, and this method can predict visibility’s trend. So we can use this method to provide the airport visibility’s objective forecast guidance products for aviation meteorological services in the future. In this paper, the Urumqi area is as the research object, to explore the depth of learning in the field of weather forecasting applications, providing a new visibility return forecast for weather forecast personnel so as to improve the visibility of the level of visibility to ensure the safe and stable operation of the airport.

Existence and uniqueness of extreme point of total power rate functional for hot rolling problem with rigid-plastic SCM model
Shuni Song,Xianghua Liu,Guodong Wang
Chinese Science Bulletin , 2000, DOI: 10.1007/BF02884894
Abstract: The total power rate functional for hot rolling problem with the rigid-plastic SCM model is considered. The gradient operator of the plastic deformation power rate functional is deduced. It is strictly monotone mapping. Further, it is proved that the frictional power rate functional is a convex functional and the tensional stress power rate functional is a linear one. Hence, the total power rate functional is a strictly convex functional. By using nonlinear functional analysis methods, the existence and uniqueness of extreme point of the functional is obtained.

材料科学技术学报 , 2003,
Abstract: The relationships among the deformation, texture and deep drawing properties of IF steel were investigated. By adopting double cold rolling (DCR) technology, the deep drawing property has been developed evidently. With the aid of orientation distribution function (ODF) analysis, it was found that he main reason for good property is the counterbalance in intensity of the ideal texture component {111} < 011 > and {111} < 112 >.
