This paper proposes an automatic computer aided diagnostic system (CAD) for detection of liver diseases like hepatoma and hemangioma from Abdominal Computed tomography (CT) images. Liver and Lesion is segmented using gray level methods and clustering. Histogram analyzer is used to fix the threshold and morphological operation is used for post processing. Rules are applied to remove the obstacle...

The field radiated fit)m an impulse radiating antenna (HL4) utilizing a reflector and driver by a step-function source consists of three distinct parts. First, there is a prepulse, which looks ikc a step function, and lasts for a time equal to twice the electrical length of the feed. Following this comes the actual impulse-like waveform. Finally, there is a small tail that appears after the imp...

in this paper, financial services in the iranian as a sector with a leontief production function, this sector buys inputs from other sectors for its productions and provides services to expedite the cash fellows and risk transformation to other sectors, the first relations are called backward linkage and the later relations are called forward linkage, for quantification of the linkage , employm...

background: increase in aquatic production is dependent on raw materials, quality of diet, feed manufacture technology and optimum feed formulation. objectives: the aim of this study was investigation and quality control feed of fft, gft1 and gft2 of rainbow trout in farm and fish feed factory producers in chaharmahal and bakhtiari province. methods: in this study samples of fft, gft1 and gft2 ...

Recognizing emotional facial expressions is a part of perceptual decision-making processes in the brain. Arriving at a decision for the brain becomes more difficult when available sensory information is limited or ambiguous. We used clear and noisy pictures with happy and angry emotional expressions and asked 32 participants to categorize these pictures based on emotions. There were significant...

View-invariant object recognition is a challenging problem that has attracted much attention among the psychology, neuroscience, and computer vision communities. Humans are notoriously good at it, even if some variations are presumably more difficult to handle than others (e.g., 3D rotations). Humans are thought to solve the problem through hierarchical processing along the ventral stream, whic...

Introduction: To estimate the accuracy levels of Lagrange, Newton backward interpolation, and linear interpolation methods in estimating the output factors for square fields used in linear accelerator for 6 MV photons at various depths. Materials and Methods: Ionization measurements were carried out in radiation field analyzer in linear accelerator for 6 MV beams at the depths of 5 and 10 cm by...
