In the software testing, source code instrumentation can be used test code coverage and memory detect, and then collecting testing data during the program dynamic running; but the way can not used to getting process run time. This paper propound kernel task hook instrumentation based on process Switch, for achieving timing relevant index of process during it's life periods, then analyzed the kernel of Linux2.6 and established instrumentation point for process scout. © 2013 IEEE.

This paper presents a non-contact measurement solution, which can be used for rapid and accurate measurement of machinery and equipment in a variety of transmission gear wear or breakage situation. This scheme is based on machine vision technology. Through the reverse engineering method we re-build the three-dimensional model of gear s from their two-dimensional image, which can make all the wear and damage morphology of gear surface comprehensively and accurately reappeared. At the same time we give a characterization of the relevant parameters of the wear and tear. Therefore, this method could solve the difficulty in terms of gear wear detection, such as operability, uncertainty and other issues. The application of this method can also provide accurate gear wear data to predict the service life and provide the essential date for the maintenance decision. © (2013) Trans Tech Publications Switzerland.
