FIELD AND SOURCE EQUIVALENCE IN SOURCE RECONSTRUCTION ON 3D SURFACES

On the source of plasma density and electric field perturbations in PMSE and PMWE regions

تشکیل ابرهای مسسفری در فصل تابستان و در ارتفاع ۸۰ تا ۹۰ کیلومتری از سطح زمین در نواحی قطبی دارای اهمیت بسیار زیادی می باشند. ارتباط مستقیم بین افزایش مشاهده این ابرها و پدیده گرم شدن کره زمین از دلایل اصلی اهمیت مطالعه این ناحیه می باشد. طبق تحقیقات انجام شده افزایش گازهای گلخانه ای باعث کاهش دما در این ناحیه از جو می شود. از طرف دیگر افزایش گاز متان و فرایند تجزیه آن توسط نور خورشید نیز باعث ا...

near-field source localization in nonhomogeneous environments

source localization is an essential part of array signal processing including radar, sonar, seismology and oceanography applications. the performance of the presented source localization methods are degraded substantially in practical situations. one of the conditions which decreases the performance o

Far-field Source Signature Reconstruction Using Direct Arrival Data

Generalized Source Shortest Paths on Polyhedral Surfaces

We present an algorithm for computing shortest paths and distances from a single generalized source (point, segment, polygonal chain or polygon) to any query point on a possibly non-convex polyhedral surface. The algorithm also handles the case in which polygonal chain or polygon obstacles on the polyhedral surface are allowed. Moreover, it easily extends to the case of several generalized sour...

Multi-Source Family Reconstruction

The complex problem of automatic family reconstruction on the basis of multiple historical sources can only be solved within the framework of a transparent and modular system. The source information (gathered from multiple sources in various tables in the Source Database) should be transformed and normalized in such a way that a source-independent representation is realized (in a second, indepe...
