A Novel Adaptive Fast Learning Algorithm for 2DPCA
Authors: Chen Liang Hwa , Chang Yen Ching , Chang Po Lun , Chang Chun Ming
Published: March 2013

We propose a novel adaptive fast learning (AFL) algorithm for two-dimensional principal component analysis (2DPCA) in this paper. As opposite to conventional PCA which is based on 1D data vectors, 2DPCA is based on 2D image matrices and thus has higher accuracy than conventional PCA when applied to applications such as face recognition, facial expression recognition, palmprint recognition, etc. Our proposed AFL algorithm simultaneously estimates both eigenvectors and corresponding eigenvalues, and then adaptively sets the learning rate parameters of neurons to ensure all neurons learning with almost the same fast speed. Requiring no image covariance matrix evaluation, the desired multiple eigenvectors of 2DPCA can thus be learned effectively in the form of weight vectors of neurons. The proposed AFL algorithm can also be applied to learning for T-2DPCA. Simulation experiments performed on face database such as the YaleB database clearly demonstrate that the proposed AFL algorithm performs very well and thus is a very effective computational tool for both 2DPCA and T-2DPCA.

Authors: Jo Hee Seung , Lee Myung Ho , Choi Dong Hoon
Published: March 2013

Machine virtualization and cloud computing environment have highlighted for last several years. This trend is based on the endeavor to enhance the utilization and reduce the ownership cost of machines. On the other hand, in aspect of high performance computing, graphics processing unit (GPU) has proved its capability for general purpose computing in many research areas. Evolving from traditional APIs such as the OpenGL and the Direct3D to program GPU as a graphics device, the CUDA of NIVDIA and the OpenCL provide more general programming environment for users. By supporting memory access model, interfaces to access GPUs directly and programming toolkits, users can perform parallel computation using the hundreds of GPU cores. In this paper, we propose a GPU virtualization mechanism to exploit GPU on virtualized cloud computing environment. Differently from the previous work which mostly reimplemented GPU programming APIs and virtual device drivers, our proposed mechanism uses the direct pass-through of PCI-E channel having GPU. The main limitation of previous approaches is virtualization overhead. Since they were focused on the sharing of GPU among virtual machines, they reimplemented GPU programming APIs at virtual machine monitor (VMM) level, and it incurred significant performance overhead. Moreover, if APIs are changed, they need to reengineer the most of APIs. In our approach, bypassing virtual machine monitor layer with negligible overhead, the mechanism can achieve similar computation performance to bare-metal system and is transparent to the GPU programming APIs.

Published: March 2013

While facing an increasingly borderless competitive global economic environment, the development of culture-driven products industries has become the dominant issues of the local economic policy. Attracting tourism by pushing the interest of people to the local culture, particularly through consuming experiences of culture-driven products, is a current trend in urban competitiveness. Cultural products are popular instruments representing local culture. They translate messages, narrate memories and historical events, and establish an emotional connection with people. This study explores the possibility of using cultural products as a city marketing strategy for the former Tainan State Magistrate Residence, which can be integrated with other cultural zones to represent Tainan City. The Tainan City government registered it as a city-level historical heritage site and completed its restoration and reuse plan in 2000. However, no practical marketing strategy has been formulated to promote the site and to raise cultural awareness among both locals and tourists. The present study adopts an empirical case generated from an outing course: a one-day cultural learning tour involving 61 student participants in the former Tainan State Magistrate Residence. Many rich identifiable cultural features were derived from the experience of the participants, which were transformed into unique and irreplaceable cultural product ideations. The findings of the case study provide a clear understanding of the dynamic relationship among cultural products, city heritage, and city marketing, which strengthens the potential of cultural storytelling through the design of cultural products for city image promotion and urban regeneration. They provide practical designers, urban planners, and policy makers a view of the importance of cultural communication media through products.

Authors: Zhang Peng , Cui Li Xin , He Le , Xia Qun Sheng
Published: March 2013

The tire dynamics simulation was done for the different speeds on the dry and wet roads with Magic Formula tire model. The coefficients of Magic Formula tire model under different conditions were obtained by means of the tire test data based on the nonlinear least squares method. The Magic Formula has a good ability to fit the test data for the longitudinal, lateral force and align moment. The tire dynamics simulation results show that at 30mph the wet tire peak longitudinal and lateral forces are only slightly less than the dry peak forces. The wet tire peak longitudinal and lateral forces decreases as the tire speed increases. This shows that the speed has a larger impact on the tire force. The align moment is relatively small. So it can be ignored in the vehicle dynamics analysis.

Authors: Wang Zhen , Yang Yang , Yang Wei Xin
Published: March 2013

Since the equipment early fault signal is very weak and unstable, it is very difficult to judge the fault type and fault degree through the traditional method of fault diagnosis .For this reason, this paper presents an effective method. Firstly, the fault signal is decomposed into a number of intrinsic mode functions (IMF) by Empirical Mode Decomposition (EMD) method, then the IMF’s energy entropy is calculated, the AR model is established, and the auto-regressive parameters are extracted. At the same time, the residual variance of the model is taken as the fault feature vector, which can be used as input parameters of SVM classifier to distinguish working state and fault types of the equipment. Finally, the validity of the proposed method is verified by taking the rolling bearing fault diagnosis as an example.

Published: March 2013

The differences of instantaneous frequency (IF) characteristics between the defect echo and the noise can be used to detect defect and suppress noise for ultrasonic testing signal. Therefore, the IF is one of the important instantaneous parameters of ultrasonic testing signal. To estimate the IF of ultrasonic testing signals more effectively, the peak of time-frequency representation (TFR) from matching pursuits (MP) decomposition is proposed. The performances of IF estimators are compared on the simulated signals at different signal-to-noise ratio (SNR) and the real ultrasonic testing signal. The simulation results present that the proposed method can estimate accurate IF at different SNR.

The microstructure and properties of the diffusion bonding joint was analyzed by means of SEM, EDS and micro-hardness tester. Experiment results show that compact bonding joint was obtained at the temperature of 480°C, holding time of 30 minutes, pressure of 10 MPa and the vacuum degree of 1.0×10-2Pa. The bonding joint consists of a interfacial diffusion region which is a mixture of Mg2Cu, MgCu2, and Mg(Cu) solid solution, and the transitional zone which is composed of Mg(Cu,Al) solid solution base and Mg17(Al, Cu)12 phase. Within the bonding joint,the micro-hardness shows a step pattern of increasing, which is well accord with the the microstructural feature of the joint.This trial has prove that using Cu as the interlayer is effective to improve the quality of the AZ31B bonding joint.

We have fabricated Aluminum Nitride (AlN) films on the quartz substrates using RF-reactive magnetron sputtering method. The conditions of the films have been performed under different concentration ratios between nitrogen and argon. We have found that all obtained films were transparent in visible wavelength. By using X-ray diffraction (XRD) technique, it was found that the (002), (102) and (103) orientations were shown in XRD patterns. The (002) orientation was dominant when nitrogen concentration (CN) was at 40%. On the other hand, the refractive index and optical band gap energy of the films were determined as a function of CN. We have found that the refractive index weakly depended on CN, while optical band gap energy did not.

The sensitization and intergranular corrosion (IGC) behavior of a novel Cr-Mn-N austenitic stainless steel (named as MPMD133) sensitized in the temperature range from 600 oC to 1000oC for 3 hours was investigated by the double loop electrochemical potentiokinetic reactivation (DL-EPR) test. The effects of the sensitization temperature on the susceptibility to IGC of MPMD133 were examined in the 0.5M H2SO4 +0.01M KSCN electrolyte solution. The results show that the degree of IGC increases as the sensitization temperature increasing till 900oC. Meanwhile it decreases rapidly when the sensitization temperature is elevated up to 1000oC, which is confirmed by the subsequent optical micrographs observation. The XRD analysis reveals that the precipitation of Cr23C6 leads to chromium depletion along the grain boundaries, consequently results in the susceptibility to IGC.

A novel type of photonic crystal fiber for high birefringence and zero-walkoff is proposed based on polymer, the fiber is composed of a solid polymer core and a cladding with square lattice elliptical air-holes along the fiber length. The optical birefringence and polarization-dependent leakage loss are studied numerically based on the full-vector finite element method(FEM). Numerical results show that the proposed fiber has heightened modal birefringence of the order of 10-2; and the leakage loss is reduced to 0.08dB/m at wavelength of 0.65μm when it has 10 rings of elliptical air-holes. So the proposed PCFs may be useful in the field of high birefringence polarization-maintaining optical communication.

Authors: Li Zheng
Published: March 2013

A nano-structured Ni(II)–baicalein(BA) film is electrodeposited on a multiwall carbon nanotube paste electrode in alkaline solution. The modified electrode shows electrocatalytic activity toward the oxidation of hydroxylamine. Kinetic parameters such as the electron transfer coefficient α, rate constant ks of the electrode reaction and the catalytic rate constant kcat of the catalytic reaction are determined. The catalytic currents present linear dependence on the concentration of hydroxylamine from 2.5×10-6 mol•L-1 to 4.0×10-4 mol•L-1 by amperometry. The detection limit and sensitivity are 6.0×10-7 mol•L-1 and 31.2 mA•L•mol-1, respectively. The modified electrode has been applied to determine hydroxylamine in water samples with satisfactory results.

With graphite, 45 steel and copper as substrates respectively, Ti(C,N)-TiB2 composite ceramic preforms with micro/nanometric grains were prepared by self-reactive sprayed forming technology. The cooling rate of spray particles deposited on different substrates was calculated by finite element method. The influence of cooling rate on morphology of micro/nanometric grains of Ti(C,N)-TiB2 composite ceramic preforms was studied by means of SEM, XRD and EDS. The results showed that the average cooling rates of particles deposited on the three kinds of substrates were 7.0×107°C/s, 8.1×107°C/s and 10.7×107°C/s respectively. The extremely quick cooling rate was the essential reason why the spray formed preforms were composed of micro/nanometric grains. The TiC0.3N0.7 grains in preforms deposited on three kinds of substrates all took on anomalous equiaxed grains. Quicker the cooling rates of the deposited particles were, smaller the grains were. The grain size of them was all less than 3μm. Whereas the influence of cooling rate on the morphology of the TiB2 grains was great. When with graphite as substrate, TiB2 took on rod-like grains with big length to diameter ratio. When with 45 steel as substrate, it took on near equiaxed grains. And when with copper as substrate, it took on lamina grains with thickness of about 100nm due to the extremely quick cooling rate and the extremely large degree of supercooling. That’s because with the change of the cooling rates, the remaining time of the liquid phases is different, so as to the growing time of the grains along the habit plane is also very different.

Isothermal compression of the TiNiFe shape memory alloy has been carried out on a Gleeble-3500 thermal simulation machine at the deformation temperature ranging from 1023K to 1323K, the strain rate ranging from 0.01s-1 to 10s-1 with total strain of 0.8. On the basis of dynamic material model, the processing map is established with two instability regions and a desirable domain which demonstrate optimum hot working conditions within the experimental parameters. By means of Electron Back Scattering Diffraction, we come to the conclusion that both dynamic recovery and dynamic recrystallization exist in the desirable domain with deformation temperature ranging 1123 K and strain rate 0.1s-1. The uneven deformation exits in the low deformation temperature with high strain rate area, such as 1023 K and10 s-1. And with 1323K and 0.01s-1 strain rate, the recrystallized grains are abnormal grow up.

Ni0.5Zn0.5Fe2O4, Ni0.3Cu0.2Zn0.5Fe2O4 and Ni0.4Co0.2Zn0.4Fe2O4 spinel ferrite nanofibers with 60–100 nm in diameter were fabricated through the sol-gel assisted electrospinning method, followed by calcination at 600°C for 2h in air. The phase structure morphology and element composition of these nanofibers were determined by XRD, FE-SEM and EDS. Magnetic measurements were used to justify the ferromagnetic properties of these nanofibers. Microwave absorption, which was in the range of 2-18 GHz, was studied by a vector network analyzer. The adoption of Cu2+ and Co2+ substitution was found to improve the microwave absorption in relation to non-substituted NiZn ferrite nanofibers. Reflection loss exceeding –5 dB is obtained between 11 and 18 GHz for silicon rubber composites containing 15 vol% nickel-based ferrite nanofibers with coating thicknesses of 3 mm. The results indicate that the prepared nickel-based ferrite nanofibers possess good electromagnetic wave absorption performance in the Ku band and have great potential as microwave absorber for practical applications.
