On the Mutual Difference for Miniature Steel Balls measured by Electric Resistance (Part 1)

EVALUATION OF WEAR AND IMPACT PROPERTIES OF GRINDING BALLS USED IN SARCHESHMEH COPPER PLANT

Abstract: Ball mills are used in the last stage of ore processing for grinding raw materials. Forged 70Cr2 alloy steel and Austempered Ductile Iron (ADI) balls are materials from which grinding balls are made for Sarcheshmeh Copper Plant (SCP) ball mills. In the present study wear and impact properties of these two kinds of balls have been investigated. Some balls randomly were selected as ...

Image Difference Visualization Based on Mutual Information

We propose algorithm for local image difference measurement for multimodal image data based on value of mutual information of both images. Algorithm works with registered gray-level images. Similarity measure takes into account entropy of compared images. Results of proposed algorithm can be used for image comparison and better difference localization. Introduction Multimodal data sets are nowa...

Statistics for dental researchers; part 1: Introduction

Learning statistics is a necessity for dental researchers. Due to daily dental science expansion, dental researchers have to study new papers in recent dental journals to remain up to date. On the other hand, knowing principles of statistics helps better understanding of the articles. Some authors revealed that knowledge of dentists about basic topics of statistics was poor. Therefore, in this ...
