China and Japan Heritages Timeline System for History Museum Data A Case of National Palace Museum and the Tokugawa Art Museum

[[abstract]]This paper describes a study in which we enable access to China and Japan cultural heritage information from two history museums, the National palace museum in Taiwan and the Tokugawa art museum in Japan. Results from these museum databases were used to develop a prototype system to demonstrate advanced cultural learning and historical timeline functionalities for foreigners. This system is based on temporal data from museum database, and provided the user with powerful data manipulation and graphical visualization tools. For instance, interactive timeline interfaces could be described which allow a viewer to scroll, change the area, select from multiple timelines, and display attributes of history events. It might become a basis of an interactive digital museum system for China and Japan heritages especially for foreign users.[[conferencetype]]國際[[conferencedate]]20110118~20110118[[booktype]]電子版[[iscallforpapers]]Y[[conferencelocation]]Tokyo, Japa

Astronomy News Element Analysis and Visualization System for the web

We investigated online astronomy news, exploited the individual space concept, and developed a news timeline to construct an interactive astronomy visualization system that integrates time and spatial concepts. Before constructing our system, we referred to the essential factor of astronomy news display modes and chose well-known astronomy Web sites as the survey objects. We investigated news interfaces and determined their interactive problems.書目待補國際20091207~20091209電子版YKaohsiung, Taiwa

Performance analysis of end-to-end SNR estimators for AF relaying

Many existing signal-to-noise ratio (SNR) estimators were designed and evaluated for conventional one-hop communications systems. However, for a relaying system, it is the end-to-end SNR that determines the system performance. In this paper, we will fill this gap by evaluating the performances of the existing SNR estimators in a dual-hop relaying system used for each hop. The probability density functions of the SNR estimators are first derived, whose parameters are fitted as functions of the sample size and the true value of SNR. Using them, the cumulative distribution functions of the end-to-end SNR and the bit error rate performance for a relaying system are derived. Numerical results show that the squared signal-to-noise variance estimator has the best performance for small SNRs and the second-order fourth-order moments estimator has the best performance for large SNRs, while the signalto-variation ratio estimator has the worst performance, among the existing SNR estimators, for AF relaying systems

Astronomy News Explorer in use of Curatorial Platform for Knowledge and Content Management of Science Education

[[abstract]]Curators wonder if the research institution’s news can be gathered efficiently, and how past news can be obtained more conveniently. The point is how to use a different perspective to search for news. To immediately read associated news with an easy browsing tool is necessary. This paper proposes a Curatorial Content Management System (CCMS) to structure news management activities for science museum curators. This system represents astronomy news collecting and news organized interactions in a way suitable for both technical oriented implementations and astronomy materials supporting. It is an interactive system that creates an interface between the curator’s knowledge and the information of astronomical expertise. By this option, curators can acquire the information of the distances and quantities of the news. Moreover, the authors analyzed the presented drawbacks of some web-based news browsing environments and describe how the nature of the system can avoid the existing problems upon news implementation.[[booktype]]電子

The reconstruction of an hermitian Toeplitz matrices with prescribed eigenpairs

In this paper we concern the reconstruction of an hermitian Toeplitz matrices with prescribed eigenpairs. Based on the fact that every centrohermitian matrix can be re- duced to a real matrix by a simple similarity transformation, we rst consider the eigenstructure of hermitian Toeplitz matrices and then discuss a related reconstruction problem. We show that the di- mension of the subspace of hermitian Toeplitz matrices with two given eigenvectors is at least two and independent of the size of the matrix, and the solution of the reconstruction problem of an hermitian Toeplitz matrix with two given eigenpairs is unique.Fundação para a Ciência e a Tecnologia (FCT) - Research Programme POCTINational Natural Science Foundation of China - nº 10771022, 10571012Scienti c Research Foundation for the Returned Overseas Chinese ScholarsState Education Ministry of China - nº 890 (2008)Major Foundation of Educational Committee of Hunan Province - nº 09A002 (2009

Characterizations and Representations of Core and Dual Core Inverses in rings

In this paper, double commutativity and the reverse order law for the core inverse are considered._en new characterizations of theMoore–Penrose inverse of a regular element are given by one-sided invertibilities in a ring. Furthermore, the characterizations and representations of the core and dual core inverses of a regular element are considered.National Natural Science Foundation of China (No.11371089).

Multi-hop relaying using energy harvesting

In this letter, the performance of multi-hop relaying using energy harvesting is evaluated. Both amplify-and-forward and decode-and-forward relaying protocols are considered. The evaluation is conducted for time-switching energy harvesting as well as power-splitting energy harvesting. The largest number of hops given an initial amount of energy from the source node is calculated. Numerical results show that, in order to extend the network coverage using multi-hop relaying, time-switching is a better option than power splitting and in some cases, decode-and-forward also supports more hops than amplify-and-forward
