Equivalent sliding mode control based on RBF neural network uses the traditional gradient descent algorithm to achieve the control function. Because of local minima, training is slow and so on. The algorithm has slow convergence, poor adaptability problems. This paper presents a RBF network based on variable learning rate of W which can be used to equivalent sliding mode control system. Experimental results of the simulation show that the new algorithm has fast convergence and tracking precision. It can effectively avoid the interference caused by unknown divergence, and have a good control of reliability. © 2010 IEEE.

Thickness accuracy is the important quality index of the hot rolling strip. Therefore, the automatic gauge control (AGC) is always the important function that the control system of hot rolling trip completes firstly. Due to the complicated rolling process, nonlinearity and time-variation of the controlled system, the simple AGC system can't obtain desirable effect. In the paper, a new single neuron-Smith prediction control system of AGC is presented. Stability analysis and the simulated experiments on this system are carried out. The simulated results indicate that the new system has the advantages of quick response, low overshooting, small steady-state error and good anti-interference ability. New control system improves the control performance of system with time delay and the accuracy of strip thickness. © 2010 IEEE.

The example-based method for generating realistic, controllable human models was presented. Users are assisted in automatically generating modifying an example body data by controlling the parameters provided. The examples from the Poser and 3D Max is preprocessed as templates. The modeling method learns from these examples the correlation between the parameters and the body geometry. After this learning process the synthesizer translates the mesh of vertices to the generation of appropriate shape and proportion of the body geometry through free-form deformation method. Finally, we demonstrate our modifier synthesizer for more subtle manipulations of example models. On any synthesized model, the underlying bone and skin structure is properly adjusted. By allowing automatic modification from a set of parameters, our approach may eventually lead to the automatic generation of a variety of population models. © 2010 IEEE.

Fingerprint recognition technology is a technology of biology- authentication widely used and legalized in international today because of its low-price and finer application. Fingerprint just is a small part of the skin, but it contains a great deal of information. The veins of the skin are different in pattern and cross point and break point. Medicine has proven that these characteristics are different for each finger and these characteristics are unique and permanent. Hardware system of fingerprint module detection is designed in the paper. This system applies SST89V564 single-chip microprocessor as its core-module and collects fingerprint by ZFM-20 fingerprint module, and then, memories fingerprint data by extended memory and displays fingerprint image by G3245H LCD. The system possesses many merits such as small-bulk and finer ratio of performance-price and rapid transmission and vivid image, and so on. It takes on practical engineering significance. © 2010 IEEE.

Heating in the ocean has continued in 2024 in response to increased greenhouse gas concentrations in the atmosphere,despite the transition from an El Ni?o to neutral conditions. In 2024, both global sea surface temperature(SST) and upper2000 m ocean heat content(OHC) reached unprecedented highs in the historical record. The 0–2000 m OHC in 2024exceeded that of 2023 by 16 ± 8 ZJ(1 Zetta Joules = 1021 Joules, with a 95% confidence interval)(IAP/CAS data), which is confirmed by two other data products: 18 ± 7 ZJ(CIGAR-RT reanalysis data) and 40 ± 31 ZJ(Copernicus Marine data,updated to November 2024). The Indian Ocean, tropical Atlantic, Mediterranean Sea, North Atlantic, North Pacific, and Southern Ocean also experienced record-high OHC values in 2024. The global SST continued its record-high values from2023 into the first half of 2024, and declined slightly in the second half of 2024, resulting in an annual mean of 0.61°C ±0.02°C(IAP/CAS data) above the 1981–2010 baseline, slightly higher than the 2023 annual-mean value(by 0.07°C ±0.02°C for IAP/CAS, 0.05°C ± 0.02°C for NOAA/NCEI, and 0.06°C ± 0.11°C for Copernicus Marine). The record-high values of 2024 SST and OHC continue to indicate unabated trends of global heating.

The problem of the robust stability and non-fragile control of closed-loop system is studied for the system with structured uncertainties both in plant and controller. Non-fragile robust stability and performance sensitivity of the closed-loop system with left coprime factor perturbations and right coprime factor perturbations are investigated respectively. and the sufficient conditions are given for the non-fragile robust stability of perturbed system under the certain conditions as well. At last the relation of non-fragile robust stability between the two aspects is given. © 2010 IEEE.
