  The objective of this study is to classify few important kidney categories by characterizing the tissues of kidney region using the unique power spectral features with ultrasound as imaging modality. The images are acquired from male and female subjects of age 4515 years. Three kidney categories namely normal, medical renal diseases and cortical cyst are considered for the analysis. The acquired images are initially pre-processed to retain the pixels-of-interest. The proposed features depend on the spatial distribution of spectral components in the kidney region. A set of power spectral features are estimated at the specific cut-off frequencies rc1 and rc2 in the spectrum and by considering global mean total power. The results obtained show that the features are highly content descriptive and provide discrete range of values for each kidney category. Such isolated feature values facilitate to identify the kidney categories objectively which may be used as a secondary observer. The proposed method and features also explores the possibility of implementing computer-aided diagnosis system exclusively for US kidney images.

  This study is concerned with a genetic algorithm based scheduling an input-queued switch. This study uses binary encoding of real parameter vectors as chromosomes as genes and as alleles. In this study we investigate that a scheduling of IQ with GA researchers obtain feasible solutions. Initial population is generated by permutation method and fitness was calculated by weighted sum of the packet arrivals. The tournament method of parent’s selection and single point crossover point is adopted. It is tested with 4x4 input queued switch. The result shows that the GA has been successfully applied to scheduling of IQ switches. Experimental results are also shown that GA based scheduling of an IQ switches have better performance in throughput and low latency.
