Authors: Zhang Da Zhi , Meng Ling Qi
Published: September 2014

Vibration appears in the main drive system of the six-roller cold rolling mill of one plant. The oscillation frequency is 2.5 Hz. The oscillation cycle is 0.4 second. The oscillation period has nothing to do with the speed. Using the finite element software ANSYS, the low natural frequency is got through the modal analysis and harmonic response analysis based on the measured vibration data from the field. Horizontal vibration is the main vibration mode and it is the electromechanical coupling vibration. Main motor is controlled by IEGT inverter of TEMIC and the low frequency harmonic component is difficult to eliminate. AC drive trap filter is designed to dodge the 2.5 Hz frequency. The solution has achieved the recognition by the TEMIC company. The problem was solved and good results were obtained.

Combining Power Adjustment and Node’s Movement for Connectivity Restoration in Sensor Networks
Authors: Wu Chun Hui , Chen Hong Sheng
Published: September 2014

Mobile sensor networks (MSNs) have many applications in recent years, especially in some harsh environment, such as battlefield reconnaissance. MSNs may suffer from a large-scale damage which causes many nodes to fail and the network to get partitioned into isolate islands. So in order to avoid negative effects on the application, restoring network connectivity is crucial in such case. In this paper, we propose a novel method, CPANMCR, which combines power adjustment and node’s movement to restore the network connectivity. In CPANMCR mainly include three phases: firstly detecting the boundary nodes of every isolate island, then adjusting the power of boundary node to restore the connection, and finally moving mobile nodes to the appropriate location to restore the connectivity of the entire network. Extensive simulation experiments demonstrate that the proposed method can guarantee network connectivity and reduce the total travel distance.

Authors: Alfraih Abdulaziz Nasser A. , Chen Wen Bo
Published: September 2014

The Network Time Protocol (NTP) is used to synchronize clocks of various computer devices such as personal computers, tablets, and phones based their set time zones. The network of devices that use these NTP servers form a huge distributed network that attracted a number of attacks from late 2013 towards early 2014. This paper presents a hands-on test of the Distributed Reflection Denial of Service (DRDoS) attack by the monlist command, provides more vulnerability in the protocol, and offers mitigation to these vulnerabilities. A Kali Linux server was used to test the monlist command on its localhost. The results showed that a request with a size of 234 bytes got a response of 4,680 bytes. A busy NTP server can return up to 600 addresses which were theoretically calculated to return approximately 48 kilobytes in 100 packets. Consequently, this results in an amplification factor of 206×. The knowledge of the way the attack can be propagated was an important step in thwarting the attack and mitigating more such threats in the same protocol.

Authors: Wang Yi , Su Xiu Qin
Published: September 2014

In this paper, a novel high-throughput method is proposed to improve the decoding efficiency of the context-based adaptive variable length coding (CAVLC) procedure of H.264/AVC. Due to the data dependency among symbols in the entropy decoding flow, the CAVLC decoder requires large computation period, which dominates the overall decoder system performance. To expedite its decoding speed, the critical path in the CAVLC decoder is first analyzed. This paper presents a double level design for H.264/AVC CAVLC decoding. In the proposed design, we exploit a predict strategy to achieve double level decoding. Experimental results show that the operation period of the proposed architecture can be reduced about 28.3% compare with the tradition CAVLC architecture. The maximum frequency can be larger than 120 MHz, which can support the real time requirement.

Published: September 2014

The basic design concept and the necessities of virtual power plant (VPP) are introduced after analyzing the future conditions of global energy demand. According to the differences in functions, VPP is divided into two roles, the commercial virtual power plant and the technical virtual power plant. After comparing their characteristics, related connections between them are proposed. Power quality control technologies and auxiliary services provided by VPP are discussed in detail based on current domestic and international research situation. Finally three scheduling control modes, the centralized mode, the decentralized mode and the distributed mode are compared. Correspondingly, the result that distributed control mode is more suitable for optimal scheduling control of VPP is pointed out.

To study rotational air flow field of rotor and complicated flow distinction owing to multi-ventilation ducts of stator in a large air-cooled turbine generator, considering axial symmetry of air supply, an experiment setup of ventilation system of semi-machine configuration was built in this paper. At condition of rotating, ventilation is measured by hot-wire anemometer. Firstly, ventilation in 16 different semi-circle radius is got. Measurement shows that ventilation in different radius varies much. Then ventilation of outlet of stator ducts is measured. The result shows that ventilation which is affected by flow back and jet less is higher. The conclusion will provide theoretical references for ventilation cooling of rotor ducts in large air-cooled turbine generators.
