Abstract Focusing on the vertical array source signal recovery method, aiming at estimation deviation caused by environment mismatch in engineering application of virtual time reversal mirror technology, this paper proposes normalized technology through theoretical derivation and analyzes performance under change signal-to-noise ratio simulation. Finally, practicability method effectiveness mod...

The article is a continuation of series articles on the use telemetry data heat network parameters. In first article, verification system based consistency with physical laws considered. second devoted to regression analysis verify data. proposed shows evaluate and predict one most important parameters heating – estimated load.
 presented results indicate that it not enough just analyze ca...

A novel method for the characterization and qualification of Hall effect thruster propellant distributors is presented. A quantitative measurement of the azimuthal number density uniformity, a metric which impacts propellant utilization, is obtained from photographs of a premixed flame anchored on the exit plane of the propellant distributor. The technique is demonstrated for three propellant d...

“Snow gone” (SGN) stage is one of the critical variables that describe the start of the official forest fire season in the Canadian Province of Alberta. In this paper, our objective is to evaluate the potential of MODIS-based indices for determining the SGN stage. Those included: (i) enhanced vegetation index (EVI), (ii) normalized difference water index (NDWI) using the shortwave infrared (SWI...

BACKGROUND To assess CT texture based quantitative imaging biomarkers in the prediction of progression free survival (PFS) and overall survival (OS) in patients with clear cell renal cell carcinoma undergoing treatment with Sunitinib. METHODS In this retrospective study, measurable lesions of 40 patients were selected based on RECIST criteria on standard contrast enhanced CT before and 2 mont...
