—In this paper, circular and hexagonal array geometries for smart antenna applications are compared. Uniform circular (UCA) and hexagonal arrays (UHA) with 18 half-wave dipole elements are examined; also planar (2 concentric rings of radiators) uniform circular (PUCA) and hexagonal arrays (PUHA) are considered. The effect of rotating the outer ring of the(More)
—Classification of video sequences based on their contents is a vital process for adaptation techniques. It helps decide which adaptation technique best fits the resource reduction requested by the client. In this paper we used the principal feature analysis algorithm to select a reduced subset of video features. The main idea is to select only one feature(More)
Background/Aim. Respectively with the prevalence of chronic hepatitis C in the world, using noninvasive methods as an alternative method in staging chronic liver diseases for avoiding the drawbacks of biopsy is significantly increasing. The aim of this study is to combine the serum biomarkers and clinical information to develop a classification model that(More)
In this paper, a novel method to estimate the shear wave speed is proposed. This method is a modified version of the lateral Time to Peak (TTP) method that estimates the induced shear wave speed. Lateral TTP algorithm finds the instance at which the maximum displacement is detected at each lateral location under examination at a certain depth. In the(More)
At the solid-liquid interface, a charge zone called the electrical double layer (EDL) appears. It is constituted of two zones of opposite sign: one in the solid and another one in the liquid. When a liquid flows through a pipe, an axial streaming current is generated. This current is due to the convection of the charges coming from the EDL. The(More)
At the solid-liquid interface, a charge zone called the Electrical Double Layer (EDL) appears. It is constituted of two zones of opposite sign, one in the solid and another one in the liquid. When a liquid flows through a pipe, there is a disturbance of the EDL and an axial streaming current is generated. This current is due to the convection of the charges(More)
It's known that any iris recognition system is composed of four steps: iris image acquisition, iris texture isolation, features extraction, and classification. In the acquisition phase, our system begins with identifying the human iris automatically in a given image using neural networks to test whether it contains iris or not .If the iris exists in the(More)
