Two-Dimensional Extensions of Neighborhood Preserving Embedding
Authors: Zhang Da Ming , Liu Hua Yong , Chen Juan , Li Lu
Published: September 2012

Neighbourhood Preserving Embedding (NPE) is a novel subspace learning algorithm, which aims at preserving the local neighbourhood structure on the data manifold and is a linear approximation to Locally Linear Embedding (LLE). However, in typical image recognition in 1D vectors space, where the number of data samples is smaller than the dimension of data space, suffering from the singularity problem of matrix, NPE algorithm cannot be implemented directly. In this paper, we investigate NPE directly on image matrix for image recognition. The proposed two-dimensional neighbourhood preserving embedding (2DNPE) and bilateral two-dimensional neighbourhood preserving embedding (B2DNPE) algorithms are all based directly on 2D image matrices rather than on 1D vectors as NPE does, thus the problem of singularity confronted in 1D case is overcome. 2DNPE performs compression only in row direction, while B2DNPE performs compression both in row and in column direction. The relation of them to 2DLPP (B2DLPP) are also presented. The proposed algorithms are evaluated on ORL face database and handwritten digits database.

Authors: Chang Xiao Lin , Liu Ji Qiang , Xing Bin , Yuan Zhong Lan
Published: September 2012

Secure channel technologies alone can not provide the sufficient protection to the server data as long as the server can not guarantee the trustworthiness of the client program which accesses the server. The current Trusted Computing solution offers the guarantee on the trustworthiness of the client program by evaluating the integrity of all executable elements on the client platform. However, this solution may not work effectively in the monolithic legacy and commodity operating system. This paper considers the remote attestation of program execution on the untrusted legacy platform. We propose an architecture, which (1) collects the run-time information of the client program in a secure, scalable and OS-transparent way, and (2) reports to the remote server the collected run-time information of the client program in a lightweight and secure way. The architecture achieves these features by exploiting the system virtualization technology, the existing VMI tools, and the time stamping functionality in TCG TPM. We give the detailed description of the architecture.

Authors: Zhang Bing , Gao Ze Hua , Gao Feng , Hsu Da Hsiung
Published: September 2012

The data traffic needed to be transferred by APs is much more than the other STAs in the IEEE802.11 DCF networks. However, APs access the wireless link with the same priority as STAs, and thus the throughput between uplink and downlink is of great injustice. In this paper, an adaptive optimization scheme is proposed to achieve fairness between uplink and downlink flows. APs monitor the growing real-time data traffic, and when the network system is in heavy traffic, APs could adaptively adjust the contention window to achieve fairness. Detailed simulation results show that the scheme can effectively adapt to various networks different in data flow numbers and packet size, and consequently achieve fairness between uplink and downlink flows with the total throughput increased.

Published: September 2012

This paper addresses the issue of increasing the efficiency of the clock skew scheduling. The past research focuses on reducing the time complexity of clock skew scheduling algorithm. However, even if an algorithm has time complexity close to linear, the flow iterations still consumes a lot of time. In this paper, a novel clock skew scheduling scheme with the feature of optimization-potential prediction is proposed. With this feature, the algorithm has timing complexity close to linear, and the number of flow iterations is decreased. The experiment results show that the proposed scheme consumes about half time and achieves almost the same optimization strength (13% highest frequency improvement of ARM1136J-FS) compared to the traditional.

Authors: Wang Ying Chun , Yang Yu Yong , Wang Mei Chun
Published: September 2012

Laser cladding technology was adopted to fabricate hydroxyapatite(HAP) and calcium phosphate compound coating according to the feature that a metallurgical bonding can be formed by laser cladding process. Compared with CO2laser, Nd-YAG laser has different wavelength(the former is 1.06μm and the latter is 10.06μm). Metal and ceramic material has quite different absorbance ability towards them and thus they can generate different laser cladding products by these two laser surface processings with different wavelength. This paper presents a new process and mechanism analysis to obtain bioceramic composite coating on Ti6Al4V substrate by Nd-YAG laser cladding. A bioceramic composite coating including HAP，Ca2P2O7，Ca3(PO4)2and calcium titanates and was successfully obtained by Nd-YAG laser cladding with pre-depositing mixed powders of CaHPO4•2H2O and CaCO3directly on Ti6Al4V substrate. Nd-YAG laser transmits mixed powders of CaHPO4•2H2O and CaCO3and the laser power is absorbed by Ti6Al4V substrate to produce a thin layer of molten region. There are mainly two kinds of chemical reaction systems in the coating during laser cladding processing. When CaHPO4•2H2O and CaCO3react together, they make calcium phosphate bioceramic products; The microstructure of the bioceramic composite coating is even and minute because of the rapid solidification in laser processing. A chemical metallergical bonding is formed between the boceramic composite coating and Ti6Al4V substrate. It can also be expected that Nd-YAG laser cladding technology can be used as a further modification procedure to enhance HAp/metal interface property.

On this foundation, it compares the two methods by large amount of simulative data. Further, it figures out the estimation value of the Failure Rate on the assumption of ‘As Good As new after repair’. There exists apparent difference from the exact value. So it shows that the assumption of ‘As Good As new after repair’ is not appropriate.

Published: September 2012

In order to study the effect of hot EGR on combustion characteristic of hydrogen internal combustion engine (HICE), experimental study was taken on a 4 cylinder, 2.0L HICE. The speed was 3000rpm, and the throttle was fully open, the load was adjusted through quality regulation. When the hydrogen flow ratio was 2.79kg /h, the ignition advanced angle was optimized as maximum brake torque (MBT) timing, then the EGR valve was opened, and EGR valve was adjusted to control the flow of exhaust gas that back into the intake manifold. The test results show that: as the EGR ratio changing from 0(the EGR valve is fully closed) to 43.8%(the EGR valve is fully opened), the in-cylinder pressure is decreasing with the EGR ratio increasing; the coefficient of variation in indicated mean effective pressure (imepCOV) is not changing significantly at high load conditions, changing range is less than 1%; CA50 is postponed from 11.8oCAto15.2 oCA with EGR ratio increasing.

Published: September 2012

To reduce the HC emissions of a CNG engine during starting period, starting experiments were carried out on a CNG engine. Injection pulse width (IPW) and spark advance angle () were controlled. The results indicate that wider injection pulse width and earlier spark timing cause higher HC emissions. To guarantee a reliable start and low HC emissions, the engine should start with relatively wider injection pulse width and earlier spark timing, and the injection pulse width and spark advance angle should be reduced gradually after the engine speed is steady.
