  • Full Article
The thermal contact resistance is a principal parameter interfering with heat transfer in a fin tube heat exchanger. The objective of the present study is to examine the heat transfer rate and thermal contact resistance of hot and cold fluids. The heat transfer rate and thermal contact resistance of hot and cold fluids have been investigated through the experimental numerical method.

Brain Tumor Detection, Classification and Feature Extraction from MRI Brain Image
  • Abstract

  • Full Article
Nowadays the use of automatic computer aided technology for the extraction of brain tumor by image segmentation process becomes greatly important. To improve the performance and reduce the complexity, the combined K-means and fuzzy C-means (FCM) clustering are investigated based on segmentation for brain tumor detection and support vector machine (SVM) is used for the classification of tumor types. Furthermore, to improve the accuracy and quality rate of the support vector machine (SVM) based classifier; relevant features are extracted from each segmented tissue of brain MRI images. The experimental results of the proposed method have been evaluated and validated for performance and quality analysis on magnetic resonance brain images, based on accuracy, sensitivity, specificity. The experimental results achieved 94.37% accuracy, 98% specificity, and 98.19% sensitivity, demonstrating the effectiveness of the proposed method for identifying normal and abnormal(i.e. Benign or Malignant) tissues from brain MR images.
