High-frequency Bistatic Scattering on Seabed and Targets: Comparison of Scaled and Full- Scale Experiments with Sea Trials

Recent uses of bistatic sonars show the advantages of decoupling transmitter and receiver(s) to optimise the information from seabed and target scattering. However, high-frequency scattering needs to be better understood, especially in complex, multiple-target environments (e.g. dumpsites or highly cluttered seabeds). Sea trials are paramount in providing acoustic measurements to validate scatt...

A New Guideline for the Allocation of Multipoles in the Multiple Multipole Method for Two Dimensional Scattering from Dielectrics

A new guideline for proper allocation of multipoles in the multiple multipole method (MMP) is proposed. In an ‘a posteriori’ approach, subspace fitting (SSF) is used to find the best location of multipole expansions for the two dimensional dielectric scattering problem. It is shown that the best location of multipole expansions (regarding their global approximating power) coincides with the med...

Environmental Impact Assessment of Erbil Dumpsite area - West of Erbil City-Iraqi Kurdistan Region.

During the last few years, the concern about the protection of the environment has largely increased due to the contaminants mainly with anthropogenic origin and have affected and continue to threaten human resources especially air quality, surface soil and groundwater. Solid wastes are produced every day in urban societies as a result of human activities and in an attempt to dispose of these m...

Impact of range straggling and multiple scattering on proton therapy of brain, using a slab head phantom

Background: The advantages of proton beam in radiation therapy- like small lateral scattering as well as absence of exit dose tail in the organs which are after the tumor- make it capable of delivering more treatment doses to the target and much lesser to the critical tissues near it. Materials and Methods: In this study, the Monte Carlo MCNPX code has been used to simulate a slab head phantom ...

3D Reconstruction of Specular Objects with Occlusion: A Shape-from-Scattering Approach

In this paper, we propose a method to measure specular objects regardless occlusion. The main contribution of this paper is that we have shown that the scattering of incident and specular reflection enable us to measure occluded surfaces. We locate objects in a tank filled with participating media, irradiate a laser beam to the objects, and observe the scattering of incident light and specular ...
