特征选择与变换的算法实现,计算贡献率与主成分分析(Feature selection and transformation algorithms to calculate the contribution rate and principal component analysis)

The ANPR (Automatic Number Plate Recognition) using ALR (Automatic line Tracking Robot) is a system designed to help in recognition of number plates of vehicles. This system is designed for the purpose of the security and it is a security system. This system is based on the image processing system. This system helps in the functions like detection of the number plates of the vehicles, processing them and using processed data for further processes like storing, allowing vehicle to pass or to reject vehicle. This system also helps to conduct the graphic images of the vehicles which can be further stored in the database in text format reducing size of data to be stored.

仿真绳动力学 模型为非弹性模型,解代数微分方程(simuliation of tether)

Filterbanks for digital hearing aids must use significantly different criteria than those designed for coding applications. For digital hearing aids, the filterbank channel gains must be adjustable over a large dynamic range to compensate for the hearing loss. This adjustability violates the alias cancellation properties of critically sampled filterbanks designed for coding. This paper describes a filterbank designed exclusively for hearing aid applications. Consideration will be given to the extremely limited memory, low delay and low power requirements that must be met in a typical hearing aid application.
