Occurrence and average behavior of pulsating aurora
Motivated by recent event studies and modeling efforts on pulsating aurora, which conclude that the precipitation energy during these events is high enough to cause significant chemical changes in the mesosphere, this study looks for the bulk behavior of auroral pulsations. Based on about 400 pulsating aurora events, we outline the typical duration, geomagnetic conditions, and change in the pea...

15 صفحه اولMapping Aurora Activity with SAR - A Case Study
Ionospheric propagation effects can have significant impact on the signal properties of Synthetic Aperture Radar (SAR) systems and they increase with decreasing carrier frequency. Recently, theoretical analyzes of ionospheric distortions in low-frequency SAR signals have indicated a multitude effects that are likely to affect the quality of SAR, interferometric SAR (InSAR), and polarimetric SAR...
متن کاملCoherent vs. Persistent Scatterers: A Case Study
In this paper a comparison between two typologies of point-like scatterers in SAR images, named Persistent Scatterers (PSs) and Coherent Scatterers (CSs) is proposed. The PSs are detected through the analysis of large stack of data, implying their temporal stability, and have been principally used for SAR interferometric applications. Differently, CSs are detected in single SAR images through t...

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
