Authors: Chou Po Huan , Lin Faa Jeng , Chen Chin Sheng , Lee Feng Chi
Published: September 2013

A three-degree-of-freedom (3-DOF) dynamic model based interval type-2 recurrent fuzzy neural network (IT2RFNN) control system is proposed in this study for a gantry position stage. To consider the effect of inter-axis mechanical coupling, a Lagrangian equation based 3-DOF dynamic model for gantry position stage is derived first. Then, to minimize the synchronous error and tracking error of the gantry position stage, the 3-DOF dynamic model based IT2RFNN control system is proposed. In this approach, the adaptive learning algorithms of the IT2RFNN on-line are derived from the Lyapunov stability theorem. Finally, some experimental results of optical inspection application are illustrated to show the validity of the proposed control approach.

Authors: Tu Yu Xi , Huang Li Ren , Ye Yun Yue , Zhang Yong , Ma Jun
Published: September 2013

In permanent magnet linear synchronous motor (PMLSM) direct drive system, disturbance caused by load disturbance and perturbation of motor parameters would reduce the control precision in a certain extent. In order to restrict the disturbance in PMLSM direct drive system, a vector control (VC) strategy based on the disturbance observer (DOB) was proposed in this investigation. By using the observed disturbance of DOB to adjust the given value of current in speed loop, the compensation for a sudden disturbance is optimized and a high precision of PMLSM drive system is obtained. For the sake of improving the dynamic performance under unknown disturbances, the traditional PID controller in speed loop was replaced by a single neuron PID controller, which leads to a good adaptive capability and a better starting performance in a given speed. Finally, a higher steady precision and robustness would be realized.

Published: September 2013

Amorphous hydrogenated carbon (α-C:H) thin films were deposited by the linear ion source (LIS)-physical vapor deposition (PVD) at the bias voltages ranging from 0V to-1500V. The characteristics such as surface topography and mechanism properties of the film were investigated under the voltage of 0V, -500V, -1000V and-1500V by using atomic force microscope (AFM), Ball Mills and Rockwell Indentation Tester. The results showed that with the increase of the bias voltage, the surface roughness of the film decreased initially and then increased. The wear resistance and compressive property were continuously improved. When the bias voltage was-1000V, the surface roughness was the lowest of 5.78nm.When the bias voltage went to-1500V, the film had the lowest wear rate of 7.8E-8 and the best compressive property. As a result, deeply understanding the effect mechanism of the bias voltage on α-C:H thin film is meaningful for the future deposition.

Authors: Xiao Han Min , Cong Su Nan , Sun Ling Hui , Zhang Hai Qin , Cheng Lin Song
Published: September 2013

Because plenty of polymers have been added in the surfactant/polymer (S/P) flooding fluid, its viscosity becomes higher. So when S/P flooding fluid flows in the stratum, its threshold pressure gradient is an important influence factor. According to study S/P flooding fluid with different viscosities that flows in different permeability cores, the variation laws of seepage curve have been obtained. The results of the study show that the seepage of S/P flooding exhibits nonlinear seepage in low velocity, and changes gradually to linear flow as the pressure gradient rises. As well, S/P flooding has obvious threshold pressure gradient when its speed is low. The threshold pressure gradient of S/P is related to the permeability of the core and its own viscosity. The higher the viscosity, the lower the permeability of the core, the threshold pressure gradient will be greater.

Prediction of resting-state electroencephalography (EEG) usinghigh-dimensional pattern is a challenge due to the uniqueness of each persons brainwave. This study uses the headache EEG recording as the example, and predicts the informative different states by using an intelligent feature selection method. Vomiting and nausea are usually appeared in headache attacks, andit is sensitive to light, sound, or movement. In this study, we use the EEG recording with four classes (inter-headache, pre-headache, headache and post-headache) as the medical database. This study focuses three merits: First, we establish two balanced datasets which contain 2-class (inter-headache and headache) and 4-class brainwave datasets from the original imbalanced headache database so that there is no bias of the prediction system. The 2-class dataset consists of 22 subjects and 176 trials, and the 4-class dataset consists of 40 subjects and 320 trials. Secondly, we propose an efficient SVM-based method for predicting the headache attacks from the EEGby using an inheritable bi-objective combinatorial genetic algorithm (IBCGA). IBCGA automatically selects important features from the brainwave, and the 2-class prediction accuracy of leave-one-trial-out independenttest is 81.25%. Third, from the analysis of the brain region and channel frequency, the brain region T4 is the most important brain regions and alpha and beta frequencies are the most informative frequencies.

Published: September 2013

There has become a bottleneck to use support vector machine (SVM) due to the problems such as slow learning speed, large buffer memory requirement, low generalization performance and so on. These problems are caused by large-scale training sample set and outlier data immixed in the other class. Aiming at these problems, this paper proposed a new reduction strategy for large-scale training sample set according to analyzing on the structure of the training sample set based on the point set theory.

In every country exists a time and frequency laboratory that operates a certain set of atomic clocks with goal to provide national approximation of UTC time scale. Generally, higher number of these interconnected clocks (Caesium primary standards and Hydrogen masers) might improve accuracy and stability of the time scale. The term interconnection in this context means that we have to transfer time between them despite of their location at geographically distant places the common method is a dedicated two-way satellite link or a GPS based system, however utilization of fibre links constantly increases. And present all-optical networks allow stable transmission of information. However to increase stability specific measures are necessary. Contribution summarizes the reasons for building of infrastructure dedicated to transfer of accurate time and frequency in the Czech Republic. It shows achieved results and indicated necessary steps for further stability improvements.

With the developing of HSE (Health, Safety, and Environment) business in China National Petroleum Corporation (CNPC), the HSE system built in 2009 has not meet the management and integration demands escalated recently. The bottleneck lies in the architecture adopting a business-oriented way that resource management has to be coupled with application management, which makes business upgrading difficult. This paper proposed a design of resource-oriented architecture to tackle the issues confronted. The proposed architecture design views resource management as an independent task instead of coupling with application development and management, and will make it easier to achieve scalable resource utilization and application management.

Published: September 2013

The strength performance of a blind bolt connection has been investigated under monotonic and cyclic loadings. However, the performance of these connections under fatigue loading remains unknown and is currently being studied. This paper examines and provides a better understanding of the fatigue performance of a blind bolt in a concrete-filled hollow section. A number of tests are conducted to determine the fatigue life of the blind connection in the concrete-filled tube. Comparison is made with the fatigue performance of a standard bolt. Analysis of the result indicates that the extended hollobolt has longer life than the hollobolt and lower fatigue life than those of the standard bolt.

Published: September 2013

The present study examines the characteristics of rectangular and circular tuned liquid dampers, which control wind-induced vibration in tall buildings, according to the natural frequency. The tuned liquid dampers (TLD) were of frequencies: 0.44Hz, 0.55Hz, 0.64Hz and 0.73Hz. The tuning feature of TLD water tanks was better in circular water tanks than in rectangular water tanks. Excitation amplitude affected the damping ratio based on energy dissipation capacity. At low excitation (below 5mm) and low natural frequency (0.44Hz), circular water tanks were advantageous over rectangular water tanks. However, at high excitation (over 5mm) and high natural frequency (over 0.55Hz), rectangular water tanks were advantageous over circular water tanks.
