Improved Matching Algorithms for Linear Face Class Model
Fu Yun,Zheng Nanning
Strategic Study of CAE 2005, Volume 7, Issue 2, Pages 47-56
An advanced matching technique for linear face class model is proposed, which can solve the problem of detailed controlling and robust iteration for the realistic facial modeling. A new method——Dynamic Gaussian Pyramid Analysis (DGPA), which combines Non-Uniform Sampling (NUS) method and Multi-Resolution Analysis, is presented. Integrating the PS Sampling and the Cluster Random Sampling, the distribution of the sampled points in each level images of the Gaussian pyramid is adjusted dynamically. In coarse-to-fine scheme, the minimization algorithm is used to compute the near global optimal solution that may fit to yield accurate model matching. Dynamic adjusting the boundary of the sampling cluster area and the resampling ratio, the detailed representations are effectively controlled, and the model creation is quite robust. An improved Stochastic Gradient Descent (SGD) algorithm based on the Correlative Disturbance (CD) and Adaptive Learning Rate (ALR) is exploited to accelerate iteration convergence and compute valid model parameters. With the examples of MPI Caucasian Face and AI&R Asian Face databases, experimental results in subjective evaluation and objective evaluation demonstrate the advanced model matching technique.

Aiming at the locale facts of difficult roof controlling for large span gateway of fully-mechanized coal faces, based on analysis of the influence factors of monolayer strata stability, the numerical simulation soft UDEC3.0 is employed to deeply research influence factors and changing rules of roof stability of the gateway which is composed by some monolayer strata. A new supporting idea of reducing span supporting function by bolts cooperating with anchor cables is brought forward by disposing anchor cables at the appropriate locations, the traditional supporting theory such as suspensory and compounding beam (arch) are still operated at the same time. A good result is achieved after the new supporting idea is applied in the large span gateway of Bulianta Colliery in Shendong diggings.

Strategic Study of CAE 2013, Volume 15, Issue 11, Pages 31-35
In the history of Chinese petroleum industry,the philosophical thinking is always used to guide practice. The Daqing Oilfield was developed based on the philosophical thoughts of Mao Zedong, i.e., On Practice and On Contradictions. Relying on the philosophical thoughts,the management and technology innovationsystem was continuously improved,and the technology management system with Daqing Oilfield characteristics was developed. This paper applies the thoughts of the "Two Theory" in oil production engineering,and analyzes the major challenges and countermeasures for the stable production of 4.0×107 to Daqing Oilfield. The scientific methodology of practice is used to guide the technical schemes and solutions. The "Two Theory" is proved to be effective to guarantee the stable production of 4.0×107 t.

Given the increasingly notable segmentation of underground space by existing subway tunnels, it is difficult to effectively and adequately develop and utilize underground space in busy parts of a city. This study presents a combined construction technology that has been developed for use in underground spaces; it includes a deformation buffer layer, a special grouting technique, jump excavation by compartment, back-pressure portal frame technology, a reinforcement technique, and the technology of a steel portioning drum or plate. These technologies have been successfully used in practical engineering. The combined construction technology presented in this paper provides a new method of solving key technical problems in underground spaces in effectively used cross-subway tunnels. As this technology has achieved significant economic and social benefits, it has valuable future applications.

In recent years, the number of coal mines and coal output grew significantly,and the coal industry of country technology level, equipment level and management level had a rapid development,but the coal mine construction standards and norms were relatively backward. So making a modern mine comprehensive technical standard became necessary. In view of this situation, based on the comprehensive promotion of mine construction standard, China Coal Group created a standard stricter than the national standard and industry standard, that is Safe and Efficient Modern Mine Technical Standards. The Standard leads the industry development direction,and is significant to improve the coal industry scientific level.

Reconstruction of a 12-lead electrocardiogram (ECG) from a serial 3-lead ECG has been researched in the past to satisfy the need for more wearing comfort and ambulatory situations. The accuracy and real-time performance of traditional methods need to be improved. In this study, we present a novel method based on convolutional neural networks (CNNs) for the synthesis of missing precordial leads. The results show that the proposed method receives better similarity and consumes less time using the PTB database. Particularly, the presented method shows outstanding performance in reconstructing the pathological ECG signal, which is crucial for cardiac diagnosis. Our CNN-based method is shown to be more accurate and time-saving for deployment in non-hospital situations to synthesize a standard 12-lead ECG from a reduced lead-set ECG recording. This is promising for real cardiac care.
