This paper presents a twice-gathering information interactive system prototype of e-government based on the condition that the Intranet and the Extranet are physical isolated.Users in the Extranet can gather links of the latest related information from client software which is previously collected by web alert in the Internet.Finally,through ferry-type transport devices,information is browsed by users in the Intranet,and it is transported to a storage device and synchronized with the web platform in the Intranet.During information gathering in the Extranet and data synchronization in the Intranet,it is essential to avoid repeated gathering and copying by means of comparing the extracted information fingerprints gathered from the web pages.This prototype uses HashTrie to store information fingerprints.During testing,the structure based on HashTrie is 2.28 times faster than the Darts(double array Trie)which is the fastest structure in the existing applied patent.The existing 12 types of high speed Hash functions serving for HashTrie are also implemented.When the dictionary content is larger than 5×105 words,the PJWHash or the SuperFastHush function can be adopted;when the dictionary content is 105 words, CalcStrCR32 and ELFHash functions can be adopted. 展开更多

We discuss the information paradox and its implications for regular black holes.Our primary focus is on Page curve using the island treatment and analyzing relevant parameters like Page time and scrambling time.Calculations without considering the island show that the entanglement entropy increases linearly and continues to infinity.When we consider the generalized entropy,we find that the island extends just beyond the horizon,leading to a constant entanglement entropy.Specifically,we find that in the early stages,the island never forms,regardless of the charge and mass configuration of the black hole. 展开更多

This paper describes the development of a new ECG tele-monitoring method and system based on the embedded web server. The system consists of ECG recorders with network interface and the embedded web server, internet networks and computers, with the system operating on browser/server(B/S) mode. The ECG recorder was designed by ARM9 (S3C2410X) and embedded operating system (Linux). Once the ECG recorder has been connected to the internet network, medical experts can use the internet to access the server of the ECG recorder, monitor ECG signals, and diagnose patients by browsing the dynamic web pages in the embedded web server. The experimental results reveal that the designed system is stable, reliable, and suitable for the use in real-time ECG tele-monitoring for both family and community health care. 展开更多

In an object-based storage system,a novel scheme named EAP(extending attributes page) is presented to enhance the metadata reliability of the system by adding the user object file information attributes page for each user object and storing the file-related attributes of each user object in object-based storage devices.The EAP scheme requires no additional hardware equipments compared to a general method which uses backup metadata servers to improve the metadata reliability.Leveraging a Markov chain,this paper compares the metadata reliability of the system using the EAP scheme with that using only metadata servers to offer the file metadata service.Our results demonstrate that the EAP scheme can dramatically enhance the reliability of storage system metadata. 展开更多

Mobile IP is an Internet standards protocol, which enhances the existing Internet Protocol (IP) to accommodate mobility. In mobile IP protocol, to find the exact location of mobile node for transferring incoming packets to them has a lot of signaling cost. So increasing the performance and decreasing the signaling cost are challenges of this protocol. Using the paging mechanism, its operation is in such a way that it can reduce Relocation update cost and save on power consumption in a mobile node. In addition, it can improve the performance of network by decreasing the need to register an idle mobile node. Mobile IP, currently does not support paging. Therefore, after introducing the mobile IP protocol and reporting related works, this paper will try to introduce a way to add paging support to the Mobile IP. Track paging is proposed to reduce the number of registration message of an idle mobile node to the mobile node’s home agent by waiving broad casting method and paging area size. Analytical results show that Track paging can significantly improve the total signaling cost of MIP vs. previous methods. Results also show that specifying the optimal paging area is critical in saving signaling cost of a MIP with paging support. 展开更多
