Abstract

Classification is one of the most important methods in data mining. These methods are used to extract meaningful information from large database which can be effectively used for predicting unknown class. The classifier based on decision tree is called Mixed Mode Data Base Miner (MMDBM) which is tested with different sorting techniques (merge sort, quick sort, radix sort) to compare the processing time to SLIQ classifier. In this paper, we carried out a comparative study on MMDBM classifier incorporating various sorting procedure by using Blood Pressure (BP) database, and finally the proposed method MMDBM classifier is one of the best classifiers among SLIQ supervised learning method. This proposed method achieved less processing time and higher rate of accuracy.

Abstract

Objectives: The objective of this work is to perform the sheet metal forming punch and die clearance for the forming of automatic ticket vending machine kiosk. Methods/Analysis: Modeling of sheet metal, punch and die is done. Sheet metal forming simulation is performed using ANSYS LS-DYNA and energy graph were obtained to validate the theoretically obtained clearance values. Findings: Different punch and die clearance values are simulated to show the wrinkling and shearing of sheet metal during the forming process. The theoretically obtained clearance value is verified with Finite Element Analysis (FEA) simulation. Applications/Improvements: This work shows the sheet metal forming and the effect of various punch and die clearance values at the time of forming operation.
