Age estimation is an important enabling capability for the near future, especially in applications related to Human Computer Interaction. Perhaps due to technical difficulties, age estimation has only recently begun to receive more attention. One of the more important pre-processing steps before age estimation is facial alignment, which spatially transforms a face image to align certain facial features,...
Wind power is currently the mainstream of China's new resource exploitation, but the excessively fast development pace has brought companies growing risk. So it's necessary to study the method how to evaluate the financial risk of wind power enterprise. In this paper, through financial risk analysis, 12 key financial indicators were selected out to build a principal component model. And it got three...
Consumption of rice is the main source of micronutrients to human in Asia. A paddy field with unknown anthropogenic contamination in Deqing County, Zhejiang Province, China was selected to characterize the spatial variability and distribution of micronutrients in rice grain and soil. A total of 96 paired soil and rice grain samples were collected at harvest. The micronutrients in the soil samples...
With the development of a company, its organizational structure tends to be more complicated, including more employees, more hierarchies and more allocations. The company then needs to allocate more resources, create more rules, and deal with more information to meet multiple business goals. The complexity of a company impacts its operations in two aspects: efficiency and quality. This paper discusses...
TD-SCDMA cell search is performed in three scenarios: downlink guide slot (DwPTs) position search, downlink synchronization code (SYNC_DL) position search and frame synchronization control. A fast method for every scenarios of downlink cell search in TD-SCDMA is proposed. Based on characteristics of frame and slot structure in TD-SCDMA, power-matching stencil method is used to find the position of...
In this paper, we develop an improved method for discrete tangent estimation based on Digital Straight Lines and Segments (DSL and DSS for short). We also compare it with an existent method proposed by Vialard. The experimental results show that the new method has an overall good performance.
In this paper a differential-coding method is applied to improved FM-DCSK transmitter to simplify the receiver configuration. Further based on our proposed scheme, a new error correction principle is presented to enhance the noise performance of the purposed system. The BER performance of the different FM-DCSK systems including proposed one is investigated over AWGN channels. Simulation results show...
