An open source array antenna toolbox implementation
… transmission of radio waves by means of phased array antennas was demonstrated. Since then, the further development of phased array radars was largely driven from a military point of view, with operational phased array systems implemented as far back as the second World War. In recent times, …

Source array and receiver array analysis of Vogtland/ West Bohemia earthquake clusters
… die Universität Potsdam ein temporäres Array in Rohrbach, in einer Epizentraldistanz von etwa 10 km und mit einer Aperatur von etwa 0.75 km. 22 Erdbeben wurden für Quellarray- beam forming ausgewählt. Quellarrays sind örtliche Cluster von Erdbeben, die von einer Empfängerstation …

Investigation of a compact acoustic source array for the active control of aircraft engine fan noise
An array of small, lightweight acoustic sources was investigated to determine how such an arrangement of sources would acoustically interact with a duct similar to that of a turbofan engine inlet. The sources were cylindrically curved aluminum panels excited in vibration by the application of a …

Inverse and transient thermal analysis for rapid hyperthermia therapy planning, delivery and evaluation
… delivery machine, an inverse algorithm based on source superposition has been developed. Numerical simulations with normalized source array for three simple geometry tumor models have been demonstrated. The simulation results show that the inverse procedure can estimate the optimal control …

TOMOGRAPHIC IMAGE RECONSTRUCTION: IMPLEMENTATION, OPTIMIZATION AND COMPARISON IN DIGITAL BREAST TOMOSYNTHESIS
… due to the movement of the single X-ray source. Dr.Otto Zhou's group proposed the concept of stationary digital breast tomosynthesis (s-DBT) using a Carbon Nano-Tube (CNT) based X-ray source array. Instead of mechanically moving a single X-ray tube, s-DBT applies a stationary X-ray source …

A Scheme for Ultra-Fast Computed Tomography Based on Stationary Multi-Beam X-ray Sources
… and radiation dose. The conceptual multi-source interior CT scheme has provided a potential solution to reduce motion artifacts and radiation exposure. This dissertation work conducted multi-facet investigations on a novel multi-source interior CT architecture (G. Cao, et. al, IEEE Access, …
