random texture defect detection by modeling the extracted features from the optimal gabor filter

in this paper, a new method is presented for the detection of defects in random textures. in the training stage, the feature vectors of the normal textures’ images are extracted by using the optimal response of gabor wavelet filters, and their probability density is estimated by means of the gaussian mixture model (gmm). in the testing stage, similar to the previous stage,at  first, the feature...

Software Defect Prediction Modeling

Defect predictors are helpful tools for project managers and developers. Accurate predictors may help reducing test times and guide developers for implementing higher quality codes. We propose a statistical defect predictor model with two major differences from the existing ones. Our model will use static code measures as input, since they can easily be collected with automated tools and preven...

Modeling Software Defect Introduction

In software estimation, it is important to recognize the strong relationships between Cost, Schedule and Quality. They form three sides of the same triangle. Beyond a certain point (the "Quality is Free" point), it is difficult to increase the quality without increasing either the cost or schedule or both for the software under development. Similarly, development schedule cannot be drastically ...

Neural Tube Defect and Folic Acid

نقص لوله عصبی یکی از ناهنجاریهای مادرزادی مهم و شایع می باشد که شیوع آن بیش از ۵/ ۴ در ۱۰۰۰ تولد زنده است. اتیولوژی و پاتوژنز بیماری هنوز ناشناخته است. مطالعات اخیر بر روی حیوانات نشان می دهد که این ناهنجاری ممکن است، ناشی از متابولیسم غیر طبیعی هموسیستئین باشد. در مطالعات اخیر مشخص شده است که پیشگیری از نقص لوله عصبی (NTD) بوسیله اسیدفولیک مؤثر می باشد.
