Bistatic configuration is an attractive concept for spaceborne and airborne SAR missions when distributed radars are necessary as example in the case of interferometric applications. The first reason important cost reduction achieved over multiple radar elements, by having only one transmitter (expensive part) receivers. most promising applications single-pass interferometry with a large baseline target or surface characterisation from bistatic scattering signature analysis. In defence...
The aim of this study was to compare the effect different mechanical surface treatments and chemical bonding protocols on tensile bond strength (TBS) aged composite. Bar specimens were produced using a nanohybrid resin composite in distilled water for 30 days. Different (diamond bur, phosphoric acid, silane, sandblasting with Al2O3 or CoJet Sand), as well (Primer/Adhesive) used prior application repair TBS measured results analyzed analysis variance (ANOVA) Student–Newman–Keuls test (α =...
Bistatic configurations have awakened a great deal of interest in the recent past among SAR research community for both airborne and spaceborne sensing. However, bistatic campaigns remain technical challenge. In this context, current experiments are helping to understand real engineering problems concerning data acquisitions. February 2003, DLR ONERA carried out successfully [1] one very first campaigns. The E-SAR RAMSES systems were flown two basic geometrical configurations, involving...
Summary We present a robust and nonparametric test for the presence of changepoint in time series, based on two-sample Hodges–Lehmann estimator. develop new limit theory class statistics U-quantile processes case short-range dependent observations. Using this theory, we derive asymptotic distribution our statistic under null hypothesis constant level. The proposed shows better overall performance normal, heavy-tailed skewed distributions than several other modifications popular cumulative...
Purpose This retrospective study aimed to evaluate the survival and success rates of ceramic partial laminate veneers. Scanning electron microscopy was used fractures marginal defects.Methods In total, 31 patients received 79 veneers on maxillary anterior teeth. After adhesive luting, restorations were evaluated by calibrated clinicians for up eight years using modified United States Public Health Service (USPHS) criteria. addition, epoxy resin replicas fabricated from silicone impressions...
SIREV (Sector Imaging Radar for Enhanced Vision) is an innovative radar system which can supply high-quality images of a sector in front aircraft under almost all weather conditions. In contrast to synthetic aperture (SAR) systems, no relative motion between sensor and targets required SIREV. The high frame repetition frequency allows us detect even very rapid changes the imaged scenes. Besides map Earth's surface, complex-valued be further processed additional information about topography...
