Homemade array of surface coils implementation for small animal magnetic resonance imaging

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 3, Page # 532–539, 2017; DOI: 10.25046/aj020368
Abstract:

Small animal modeling is an exciting research field where human pathogenic frameworks can be replicated in a controlled environment. Accurate Imaging is in high demand when modeling abnormalities and, magnetic resonance imaging plays a vital role due to its demonstrated lowest intrusion when compared with other imaging methods. However, the required high-resolution yields low-quality images…

Singular Integral Equations in Electromagnetic Waves Reflection Modeling

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 3, Page # 82–87, 2017; DOI: 10.25046/aj020312
Abstract:

The processes of reflection of three-dimensional electromagnetic waves by locally irregular media interfaces are investigated. The problem under study is mathematically reduced to the solution of a boundary value problem for the Maxwell equations in an infinite space with an irregular boundary. In order to develop a numerical algorithm, the potential theory and a special…

Transmit / Received Beamforming for Frequency Diverse Array with Symmetrical frequency offsets

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 3, Page # 1–6, 2017; DOI: 10.25046/aj020301
Abstract:

Frequency diverse array (FDA) employs a small frequency increment across its array elements to provide range, angle and time dependent beampattern. In most radar systems, FDA with linear frequency offsets have been employed. But, its transmit beampattern is coupled in range and angle dimensions, which may degrade the output signal-to-interference-plus-noise ratio performance. Note that nonlinear…

Spatial Sampling Requirements for Received Signal Level Measurements in Cellular Networks of Suburban Area

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 1, Page # 277–287, 2017; DOI: 10.25046/aj020134
Abstract:

A process for the determination of a required spatial resolution in the collection of the Received Signal Level (RSL) is discussed. This method considers RSL measurements as a three dimensional surface that is sampled through the data collection process. In addition, it is difficult to collect RSL measurements for an entire coverage area because of…
