Considerations for Statistical Analysis of Nondestructive Evaluation Data: Hit/Miss Analysis
This paper examines recent developments in the statistical analysis of Nondestructive Evaluation (NDE) data, and suggests improvements to conventional analysis. This paper focuses on hit/miss or Bernoulli data analysis. POD evaluation is a conventional methodology used to quantify reliability of inspections in many industries. Hit/miss data is still commonly used and many developments in statistical analysis have occurred in the last few decades; thus, this paper focuses on hit/miss analysis only
The methods of crop disease stress detecting based on remote sensing technology,image processing technique and AES(agricultural expert system),the development of these three methods and comparison of their advantage and defect were reviewed. The study state of NAH(near field acoustic holography)was introduced. A study method of crop disease stress detecting based on NAH theory was proposed,which exploits a new approach for integrated accurate prevention and cure of crop disease.
