In this paper, we investigate various surface structures of oxygen adsorption on Pd doping Zn-terminated ZnO (0001) by DFT. The results show that oxygen atom prefers to be adsorbed on the H sites of Pd substituting Zn atom of first Zn-O bilayers. The calculated PDOS indicates that a stronger interaction between adsorbed O2p and Pd4d orbitals has been happened at near the Fermi level. Finally, the...
The simple multi-period repetitive control system proposed by Yamada and Takenaga is a type of servomechanism for periodic reference inputs. This system follows a periodic reference input with a small steady-state error, even if there is periodic disturbance or uncertainty in the plant. In addition, simple multi-period repetitive control systems ensure that transfer functions from the periodic reference...
In this paper, we examine the parameterization of all disturbance observers for time-delay plants with any input and output disturbances. The disturbance observers have been used to estimate the disturbance in the plant. Several papers on design methods of disturbance observers have been published. Recently, the parameterization of all disturbance observers for plants with any input and output disturbances...
A novel planar tunable bandpass filter using the centrally-loaded short-ended resonator is presented in this paper. Characterized by theoretical analysis, the proposed structure is founded to have the advantage that the fundamental frequency can be tuned while the second harmonic remains almost unchanged. By controlling the voltage, the lower passband can be tuned in a wide frequency range. To demonstrate...
This paper presents a novel random forest based method to build mid-level features describing spatial and temporal structure information for activity recognition. Our model consists of two separate parts, spatial part and temporal part, which are employed to capture the distinctive characteristics in spatial and temporal domains of activity analysis. In the spatial part, densely sampled low level...
This research paper discusses the controled design process of using a new ICT approach to theorize a language learning model in the context of language learning. It starts with the introduction of ICT. Then the relateed ICT affordances are explored. After it, the controlled design process of using a new ICT approach is stated which may be suitable to language learning. Finally, the factors which lead...
Visual prosthesis can restore some level of visual function to blind individuals, which is founded on the visual percepts elicited by electrical stimulation. This paper presents a type of optic nerve prosthesis consisting of camera, image processing system and neural electrical stimulator, which is aimed at promoting quality of life for those suffering from visual loss by functional vision restoration.
In this paper, we propose the parameterization of all robust stabilizing simple multi-period repetitive controllers for multiple-input/multiple-output (MIMO) plants with specified input-output frequency characteristic. Recently, Sakanushi et al. proposed the parameterization of all robust stabilizing simple multi-period repetitive controllers such that the controller works as a robust stabilizing...
The Fixed-Dimension particle swarm optimization (PSO) can't be used to solve the mobile agent (MA) routing problem where the number of sensor nodes which can be viewed as the dimension of particle is not always fixed, since the updating formulae are only fit for particles of same dimension to update their velocity and position. To solve MA routing problem, a variable-dimension PSO based on chord-length...
In this paper, we present a novel dual-band miniaturized bandpass filter. The quarter-wavelength stepped impedance resonators are used to generate dual-band response. For circuit size reduction, the resonators are folded and coupled by a parallel microstrip line. Four transmission zeros are created near the passband, resulting high selectivity. The area of the filter is only 6.7 mm × 7.7 mm (0.098λ...
As a promising technique of improving the attainable bandwidth efficiency, cognitive radio (CR) has attracted substantial attention from both the academic and industrial communities. In order to improve the performance of the secondary user (SU), a novel hybrid CR system is introduced, which combines the conventional interweave and underlay paradigms for enhancing the chances of the SU to access the...
Functional modeling has been widely researched in the past decades and is considered to be effective in assisting concept design. However, construction of substantial design repository with abundant knowledge maintenance is still a problem. in this paper, we propose a model and approach for retrieve functional knowledge from existing products. First, we propose the functional knowledge retrieval model...
We proposed a scale adaptive Kalman filter algorithm based on quaternion correlation of color image. Kalman filter is used to predict the object motion direction and define the searching window. In the searching window, the correlation of object and the image is calculated to get the accurate position of the object. Scale adaptive method is efficient to the situation of object size changing. Experiments...
An adaptive bit-allocation method based on perceptual quality smoothing for wireless video communications is proposed. A visual attention model is build by considering skin, motion and position. Then the perceptual video quality distortion is predicted using the visual attention model and channel state information. Finally the MB target bits are allocated according to the predicted perceptual video...
In this paper, we proposed a super pixel based depth map propagation algorithm for the application in 2D to 3D video conversion. The proposed algorithm employs four main processes to generate depth maps for all frames in video sequences. First, the depth map of the key frames in the input sequences are generated by manual work. Second, the frames in the input sequences are over-segmented by Simple...
With shrinking transistor feature size, lowering nodal capacitance and supply voltage at new technology generations, microprocessors are becoming more vulnerable to single-event upsets and transients, a.k.a., soft errors. While chip-multiprocessor (CMP) architecture has been employed in mainstream microprocessors and the number of on-chip processor cores keeps increasing, the system-level reliability...
In the knowledge economy, the intellectual capital which has replaced the traditional production elements becomes the most important strategic resources of enterprise. This change will inevitably influence the original evolution theory of core ability. Based on the theory of enterprise resource and integration theory, we proposed a new perspective that effectively integrated intellectual capital constitute...
In China, innovations in laboratories or lectures for fundamental required courses are rare.
