On Multiple Frequency Power Density Measurements
We shall give a priori conditions on the illuminations φi such that the solutions to the Helmholtz equation { −div(a∇ui)− k q ui = 0 in Ω, ui = φi on ∂Ω, and their gradients satisfy certain non-zero and linear independence properties inside the domain Ω, provided that a finite number of frequencies k are chosen in a fixed range. These conditions are independent of the coefficients, in contrast ...
متن کاملUnsupervised Disaggregation of Low Frequency Power Measurements
Fear of increasing prices and concern about climate change are motivating residential power conservation efforts. We investigate the effectiveness of several unsupervised disaggregation methods on low frequency power measurements collected in real homes. Specifically, we consider variants of the factorial hidden Markov model. Our results indicate that a conditional factorial hidden semi-Markov ...
متن کاملMeasurement and Computational Modeling of Radio-Frequency Electromagnetic Power Density Around GSM Base Transceiver Station Antennas
Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...
متن کاملInverse anisotropic diffusion from power density measurements in two dimensions
This paper concerns the reconstruction of an anisotropic diffusion tensor γ = (γij)1≤i,j≤2 from knowledge of internal functionals of the form γ∇ui ·∇uj with ui for 1 ≤ i ≤ I solutions of the elliptic equation ∇·γ∇ui = 0 on a two dimensional bounded domain with appropriate boundary conditions. We show that for I = 4 and appropriately chosen boundary conditions, γ may uniquely and stably be recon...
متن کاملAbsolute scale power measurements of frequency-locked coherent transition radiation
We report the absolute power measurement of frequency-locked terahertz coherent transition radiation (CTR) from a train of electron bunches produced by a 17.14 GHz accelerator. Frequency measurements were obtained by two independent techniques: a wave meter with a video diode detector, and a double heterodyne system. Good agreement was seen between these two techniques. The emitted radiation wa...
