Change in Surface Profiles by Heat Treatment

Change Profiles

In this paper we introduce a generalization of association rules: change profiles. We analyze their properties, describe their relationship to other structures in pattern discovery and sketch their possible applications. We study how the frequent patterns can be clustered based on their change profiles and propose methods for approximating the frequencies of the patterns from the approximate ch...

An Analytical Model of Heat Flux in Laser Surface Treatment

Hardness Prediction in Multi-Pass Direct Diode Laser Heat Treatment by On- Line Surface Temperature Monitoring

This study was attempted to develop a process model, using the temperature values measured by the coupled infrared temperature measurement system (pyrometer and camera) correlated with the measured values of case depth hardness of the tool steel AISI S7 (hypoeutectoid steel) for the specified multi-pass laser heat treatment conditions (1000–2500 J). A number of heat treatment experiments by cha...

Climate change Effects of Surface soil temperature profile in Ahwaz

In arid and semi-arid regions, soil surface warming is a considerable phenomenon causing a high thermal gradient which makes water flow intensely. The degree of soil temperature is effective on crop production, plant growth and soil microorganisms. In recent years, the ascending trend of temperature has been substantially noticed by researchers in the issues of pointwise climate change and at w...
