The efficiency optimization control method based on loss model has the advantages of clear physical meaning and fast optimization speed. However, this method is sensitive to the real-time parameters of the motor in the model. To improve the observation effect, it is necessary to accurately obtain the real-time parameters of the motor in the loss model. By designing a stable adaptive law, the key parameters in the loss model are identified adaptively; In order to improve the observing speed and robustness of the state observer for induction motor, the pole placement of the feedback matrix with iron loss is carried out; In order to improve the performance of the algorithm, an adaptive identification algorithm for key parameters is designed according to the stability law, and the theory is verified by simulation.

Registration of pathological section images is an important part of three-dimensional reconstruction of sections. In this paper, a registration method was proposed to solve the problem of mismatching of pathological section images of pulmonary nodules. Firstly, rough matching is performed, and the feature points are extracted according to the scale-invariant feature transform (SIFT) algorithm. Then fast sparse coding (FSC) is used for fine matching to eliminate mismatched pairs. The algorithm presented in this paper is applied to the registration between sequence sections of pulmonary nodules. The experimental results show that the algorithm can effectively find more matching point pairs, accurately remove the false matching point pairs, and significantly improve the registration accuracy.

The crystallization of phase change memories (PCM) is usually described by a Johnson-Mehl-Avrami(JMA) equation in a SPICE model. In this work recent ab initio molecular dynamic simulation results are used for the JMA equation benchmark. It is found that: (a) the commonly used JMA equation does not account for the incubation period at the initial stage of phase change memory crystallization, even the equation is easily implemented with a sub-circuit. (b) the JMA equation based on the Arrhenius formula cannot reflect the crystallization rate with temperature. This paper proposes a crystallization model that can reproduce the incubation period and the crystallization rate dependence on temperature, thus improves the model accuracy.

Though current face recognition systems perform well in relatively constrained scenes, they are often affected by secondary creation of netizens, serious image blurring and abundant posture changes in real-world Internet videos. Focusing on these problems, we propose a face recognition model names Internet Video-based Face Recognition Network (IVFRNet) based on deep learning for real Internet videos. And we propose a weighted loss function to enhance the ability of learned features. To test the model, we construct a small-scale real-world Internet video-based face dataset. The experiment results show that our method outperforms the origin method.

Capacitor voltage balancing strategy for Submodules (SMs) is one of the key technologies for modular multi-level converters(MMC). The conventional strategy has the problems of large computation and high switching frequency of devices. In order to solve these problems, a mark and operation voltage balancing strategy (MOVBS) is proposed. This strategy marks SMs with two different labels according to the amplitude of capacitor voltage of SMs and current direction of arms, then do sorting and selecting operations to SMs based on the marking results. It reduces sorting times, switching frequency and power loss of devices. For capacitor voltage sorting process, a binary radix sorting algorithm(BRSA) is proposed to improve sorting speed and efficiency of MOVBS. Finally, the feasibility and effectiveness of the MOVBS is verified with a 11-level MMC-HVDC simulation model created in Matlab/Simulink.

The surface acoustic wave (SAW) technique is valuable to determine the property of thin film because it requires only elastic deformation. It features non-destructive measurement, easy operation, time-saving and isolates substrate coupling. In the recent study, the surface acoustic wave technique with cohesive zone model (CZM-SAW) is proposed to measure the film Young’s modulus and adhesion simultaneously. In this study, the simultaneous CZM-SAW technique is further studied by the experimental study. The experimental results show that for the film with bad adhesion property and porous low-k film with lower Young’s modulus, for the reliability of measuring results, it is highly required to use simultaneous CZM-SAW technique to measure the film Young’s modulus and adhesion. Moreover, the film test results are compared with nano-indentation test and nano-scratch test. By comparison, the unique advantages of the CZM-SAW technique are well demonstrated.

A effective method to enhance the holding voltage of LVTSCR for electrostatic discharge (ESD) protection applications has been proposed and verified in a 55 nm epitaxial CMOS process. The proposed method improves the holding voltage by removing the STI in NW and adjusting the NMOS gate length. In addition, it can provide an good robustness for ESD protection. Measured results show that the holding voltage can be improved 66% approximately.

In this paper, we have demonstrated high performance back-gated MoS2 MOSFETs with scandium (Sc) contact and high-k ZrO2 dielectrics for improved contact resistance and electron mobility. Record drain current of 200 µA/µm has been achieved for 1-µm channel length multilayer MoS2 MOSFETs on ZrO2/Si substrates. The intrinsic contact resistance of low work function metal Sc on exfoliated MoS2 with strong gating effect on source region is significantly decreased to 0.9 kΩ·µm. By taking the impact of contact resistance into consideration, the intrinsic mobility extracted from Y function technique is 132 cm2/Vs, 3 times higher than SiO2 substrate, originating from the significant screening effect of high-k ZrO2 dielectrics on the impurity scattering.
