This paper describes the algorithms analysis and design course that uses ACM-ICPC programming competition problems as the basis for the lectures, homework and exams. Programming contest has certain timeliness, openness and objectivity of evaluation. By taking part in programming competitions students can improve solving problems and programming skills. The course of algorithm analysis and design presents the solution strategies of a number of specific issues (such as the sorting problems, search problems, path problems, combinatorial problems, etc.) so that students can master the algorithm design strategies and analysis methods. We prepare many problems for each issue in the online judgment system (OJS). By using OJS, we carry out all experiments and examinations in the specified times. After solving some problem, students submit the code to OJS through browser. We can output the student codes to further analysis in the background management system. Online judge system provides an open, independent teaching platform for students to learn the course knowledge. With OJS students can submit their code at any time and any where.

Authors: Li Bin , Zheng Wei , Ren Shu Bo , Wu Jian Jun
Published: September 2013

Adapted parameters of OFDM signals can bring performance improvement in mobile satellite communications. This paper firstly analyzes the effect of cyclic-prefix (CP) length and sub-carrier bandwidth on system interference and capacity. This effect can be described by a formula which consists of system capacity, CP length and sub-carrier bandwidth. Then using this formula, a method to select the optimal parameters is given. In the end, a numerical calculation is performed to figure out the optimal parameters, considering the multipath delay spread and Doppler spread in satellite channel. It comes up that in satellite channel the CP is not very effective to improve the system performance and a wider sub-carrier bandwidth is desired.

Published: September 2013

In this paper, the airflow of two different chamber structures is analyzed contrastively in the sensitive element of fluidic gyroscopes. Using ANSYS-FLOTRAN CFD software, the finite element simulation is conducted by a series of procedures, such as two-dimensional model building of fluidic gyroscope, meshing, loads applying and equation solving, we calculate the two dimensional airflow distribution of rectangle chamber and streamline chamber in sensitive element of fluidic gyroscope. The results show that the airflow velocity of the exit section in the streamline chamber which is 28.87% of the nozzle velocity is higher than that in the rectangle chamber structure, so the streamline chamber structure brings airflow together to a certain extent, and it also reduces the airflow accumulation in the chamber and smoothes airflow within the loop channel, lastly velocity gradient change in the streamline chamber is greater than that in the rectangle chamber, and the resolution of fluidic gyroscope is better than that with rectangle chamber.

A Multicast Routing Algorithm with Cost, Delay and Bandwidth Constraints
Authors: Li Yuan Chen , Kuang Guo Fang
Published: September 2013

Quality of service (QoS) generally assumes more than one QoS measure which implies that routing can be categorized as an instance of routing subject to multiple constraints: such as cost, delay, bandwidth, etc. The problem of constructing multicast trees is studied to meet the QoS requirements where it is necessary to provide bounded constraints among the source and all destinations while keeping the cost of the multicast tree low. So, a kind of source-destination QoS multicast routing problem is addressed about communication networks. The algorithm we presented takes bandwidth, delay and loss rate as premise, constructs routing selected function based on shortest path, modifies selected path according to the function above so as to fit multi-QoS parameters. Simulation results show that the algorithm has both lower delay and better performance and can be extended to cases of multiple QoS parameters conveniently.

Deep web data integration has become the center of many research efforts in the recent few years. Near duplicate detection is very important for deep web integration system, there are seldom researches focusing on integrating deep web Integration and near duplicate detection together. In this paper, we develop a integration system, DWI-ndfree to solve this problem. The wrapper of DWI-ndfree consists of four parts: the form filler, the navigator, the extractor and the near duplicate detector. To find near duplicate records, we propose efficient algorithm CheckNearDuplicate. DWI-ndfree can integrate deep web data with near duplicate free and has been used to execute several web extraction and integration tasks efficiently.

Software development method based on component is currently a popular software production technology, its core around the component development and assembly technology. But how to combine the practical application requirements implementation based on component composition software development process is a worth studying further. According to the development of component technology, put forward a kind of network learning platform development framework based on component assembly, and study the website of component development and assembly method, apply this technology to the development of our online learning platform, results show the effectiveness of the proposed method.

Multi-Path Relay Selection Based on Radio and Television Business
Authors: Zhang Chao Yi , Zhao Yan Dong
Published: September 2013

This paper presents a relay selection method for radio and television business, this method uses nodes time-delay and power information, obtains the value of network interrupt as decision threshold, then selects the relay node. At same time this paper proposes an optimal relay selection strategy which can minimize the network interrupt probability combination with power distributionMulti-Path Relay Routing Protocol, this protocol can change the appropriate route path according to the dynamic network. Simulation results show that this protocol can extend cells coverage area, reduce time-delay and increase system throughput, improve system spectral efficiency, and enhance Qos of radio and television business.

P2P(peer to peer) live streaming is currently a popular research topic, but for the defective of system architecture and scheduling policy, existing P2P streaming applications have poor user experience, such as long startup delay, long playback delay, and low playback continuity. In this paper, we aim at reducing the playback delay from the source in the environment of heterogeneous upload bandwidth, heterogeneous and dynamic propagation delays. We propose a neighbor selection method in order to utilize the capacity of the peer and consider their scheduler playback deadline. This new peering strategy typically leads to low scheduling delays and improve the playback continuity. Finally we apply a receiver driven chunk selection with a mix scheduling algorithm. Through simulation, we can observe that our scheduler can outperform.
HChord: A Hierarchical Chord Model
Authors: Yan Li , Li Ying Fang
Published: September 2013

This paper proposed a new structural overlay model HChord. This model employs layered structure, and when constructing the network logical topology of peer nodes, it can detect rock-bottom physical network logical topology fast and efficiently and make it suitable to the rock-bottom network environment, and make the former be consistent to the latter as much as possible and then improve the whole performance of the systems. The goal is to construct a topology-aware overlay network, and improve the finding speed of information, and reduce unnecessary data transmission in networks.
