in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
SAR simulators are important tools for developing new SAR systems as well as for supporting the analysis of acquired SAR data. Using modern graphics cards for SAR simulation, even complex environments can be simulated in real-time. This is realized by implementing SAR geometry and radiometry within standard graphics hardware, which nowadays offers 3D hardware acceleration and programmable graph...
To address increasing water demands in expanding cities, many aquifers Mexico are overexploited and deplete. The resulting land subsidence often combines with ground faulting/fracturing damage to infrastructure. This study provides the longest Synthetic Aperture Radar (SAR) survey ever undertaken for Aguascalientes Valley, aimed constrain its structurally-controlled process induced risk. 275 ER...
The performance of the ERS-2 Synthetic Aperture Radar (SAR) is routinely assessed at the ESA Product and Archiving Facilities (PAFs) via a variety of quality assessment and calibration measures. This paper gives the latest ERS-2 SAR quality assessment and calibration results including updates to ERS-2 SAR internal calibration and stability, updates to the ERS-2 nominal replica pulse correction ...

abstract recent studies suggest that prelistening activities play an important role in the development of listening comprehension (e.g. long 1990;chiang and dunkel 1992; schmidt-rinehart 1994; jensen and hansen 1995; robinson et al., 1995; buck, 1995; foster and skehan,1996; teng 1996; robinson, 2001; chang and read 2006). in line with previous studies and to shed light on a new aspect of sche...
The paper focuses on the differential interferometric SAR (Synthetic Aperture Radar) technique for the monitoring of terrain surface deformations. The paper begins with a concise description of the properties of the differential interferometric phase, which represents the main observation for the estimation of the deformations. Then the paper discusses of the main features of a new interferomet...
