Atmospheric effects are among the primary error sources affecting accuracy of interferometric synthetic aperture radar (InSAR). The topography-dependent atmospheric effect is particularly noteworthy in reservoir areas for landslide monitoring utilizing InSAR, which must be effectively corrected to complete InSAR high-accuracy measurement. This paper proposed a correction method based on Multi-L...

Shape from focus is an accurate, but relatively time-consuming, 3D profilometry technique (compared to e.g., laser triangulation or fringe projection). This the case because a large amount of data that needs be captured and processed obtain measurements. In this paper, we propose two-step shape-from-focus measurement approach can improve speed with 40%. By using faster create coarse unknown tar...

Local wisdoms such as a tradition, land-use system and etc. had sometimes mitigated tsunami damages in Indonesia. The effective use of those local wisdoms is strongly desired especially in developing countries, because it is quite difficult for those countries to allocate enough budgets for constructing hard type countermeasures against tsunami. Among local wisdoms against tsunami hazard, this ...

Spatial and temporal variations in the vertical stratification of the troposphere introduce significant propagation delays in interferometric synthetic aperture radar (InSAR) observations. Observations of small amplitude surface deformations and regional subsidence rates are plagued by tropospheric delays, and strongly correlated with topographic height variations. Phase-based tropospheric corr...

PURPOSE To evaluate the safety, efficacy, and contralateral eye comparison of topography-guided myopic LASIK with two different refraction treatment strategies. SETTING Private clinical ophthalmology practice. PATIENTS AND METHODS A total of 100 eyes (50 patients) in consecutive cases of myopic topography-guided LASIK procedures with the same refractive platform (FS200 femtosecond and EX500...
