Modulation Classification Based on Constellation Shape Using TTSAS Algorithm and Template Matching 43-55
The automatic recognition of the modulation format of a detected signal, the intermediate step between signal detection and demodulation, is a major task of an intelligent receiver, with various civilian and military applications.

Training Set Compression by Incremental Clustering 56-64
Compression of training sets is a technique for reducing training set size without degrading classification accuracy. By reducing the size of a training set, training will be more efficient in addition to saving storage space.

Convergence of the Mean Shift Using the Infinity Norm in Image Segmentation 32-42
 In this work a comparison between two algorithms for image segmentation via the mean shift is carried out. These algorithms apply recursively the mean shift filtering by using the euclidean and infinity norms in order to define pixel neighborhoods.

The Analysis of Software Complexity Using Stochastic Metric Selection 19-31
The automated prediction of qualitative attributes such as software complexity is a desirable software engineering goal. A potential technique is to use software metrics as quantitative predictors for these kinds of attributes.

Power Scaling of Chemiresistive Sensor Array Data for Odor Classification 65-74
Steady state response of chemiresistive sensors like metal oxide and conducting polymer composite (CPC) exhibit a power law dependency on exposed analyte concentration/vapor pressure.

A Brief Survey of Color Image Preprocessing and Segmentation Techniques 120-129
Multichannel information processing from a diverse range of channel information is highly time- and space-complex owing to the variety and enormity of underlying data.
