Automatic discrimination of music mood is one important field of MIR. Considering the difference of Chinese traditional music and Western classical music, it is necessary to study these two kinds of music's mood taxonomy. In this paper, the mood taxonomy models of Chinese traditional music and Western classical music are implemented, and then three content feature sets are extracted directly from the waveform audio clips. Finally, music clips are classified by three feature sets and their combination using Bayesian network classifier. The experiment results indicate that the detection rate of Chinese traditional music mood taxonomy is lower than that of Western classical music mood taxonomy no matter using single feature set or their combinations, that is to say the contribution of different feature set to music mood taxonomy is different, and the detection rate improves obviously when combining three feature sets both for Chinese traditional music and Western classical music.

Objectives: an important part of digital image processing is recognition of patterns. Iris recognition is an important application of the same. As a result of the fact that CHT lacks speed due to its high time complexity, it is useful to recognize valid regions and make these regions the only regions to process. Extracting a valid region from the image not only reduces the image storage and the quantity of operations, it also improves the speed of the process. The objective of the work is to describe a method for enhancing the speed of extracting circle i.e. iris from the image without compromising the accuracy of the technique. A modified version of Hierarchical Hough transform is also proposed which further reduces the time taken to detect iris. An exhaustive analysis is conducted for a large number of iris images and comparison results are shown. Method: The HT space is limited by dividing it into nine equal parts and then the center most space is extracted as the valid region. Then CHT and HHT transformations are applied on the valid region. Results: About 88.77% of maximum improvement and 87.989 % of average improvement is recorded in time of execution of proposed CHT in comparison to existing CHT. Whereas, run time of HHT and proposed HHT when compared, results show that the maximum performance rate is 86.649% and average performance rate is 46.81%. Conclusion: in case of HT base detection methods, execution speed is directly proportional to the number of edge pixels in input image. Restricting the number of pixels provides the advantage of considerably simplified computations, and hence faster algorithms. The work documents that an aggregate comparison of proposed transformations with existing transformations has achieved a faster yet accurate method to recognize iris.

For ScanSAR the mosaic of subswaths' images is very important. An improved method for scanSAR to process the mosaicking by using Range-Doppler location model is proposed in this paper. It is based on the precision of the R-D location method. This method avoids the pixel defocused and the simulation results are satisfied in practice.

The controller design is a challenging task for the electric propulsion system (EPS) of the hybrid electric vehicle (HEV), which influences the economical efficiency and emission performance of HEV significantly. A single-axle parallel hybrid powertrain configuration for the IVECO vehicle is described firstly. Secondly, a DSP-based controller design procedure including hardware and software is given in detail. Finally, the controller with the integrated starter/generator (ISG) is tested in the test bench. The test data shows that the controller works well together with ISG and the controller satisfies the performance requirements of the single-axle hybrid powertrain.

The paper calculated the dispersion characteristic of asymmetrical coplanar waveguide (ACPW) using FDTD method. The results of theoretical calculation show very good agreement with XFDTD formulation and experimental data over a wide frequency range. And the time of the FDTD calculation is about one fourth of XFDTD formulation. On this basis, a novel approach for designing a UWB ACPW to slotline transition is presented. A slotline hollow patch creates open circuit conditions on one arm of the ACPW and resonates the transition so that maximum power transfer may occur. The S-parameters of ACPW-Slotline transition was calculated using FDTD method based on Mur-PML absorbing boundary condition. The results agree well with available theoretical and experimental data over a wide frequency range. It is shown that ACPW is easier to connect with slotline in circuit structure and impendence match compare with symmetrical CPW.

The recent advances in sensor technologies have made these small, tiny devices much cheaper and convenient to use in many different applications, for example, the weather and environmental monitoring fields, the hospital and factory operation sites, on the traffic road and moving vehicles and so on. Data loss and corruption is inevitable in wireless sensor networks due to the wireless interference, limited sensor power and outlier from malicious electronic devices and so on. Therefore, before processing sensor data in different wireless sensor network applications, certain data cleaning steps need to be performed to ensure the data quality, such as dealing with outliers, missing sensor readings, and noisy data. In this paper, we discuss the issues need to be considered in the data cleaning steps of this integrated data cleaning model for signal processing in wireless sensor networks. We also present an integrated model for data cleaning on signal processing systems in wireless sensor network to deal with different data cleaning problems.

A broadband beamforming method based on wavelet filterbanks and adaptive beamforming is proposed for speech enhancement in this paper. First, using the wavelet analysis filterbanks, noisy speech signals are transformed into wavelet domain with wavelet coefficients as output. Then the beamforming based on generalized sidelobe canceller (GSC) operates on the wavelet coefficients. Finally, the enhanced full-band speech signals were finally reconstructed by synthesizing the enhanced subband speech signals by used of the wavelet synthesis filterbanks. Simulation results demonstrate its effect.
