Multi-specimen and multi-site calibration of Aleutian coralline algal Mg/Ca to sea surface temperature

Multi-element sea surface temperature measurement using coral substructures

Multicentennial record of Labrador Sea primary productivity and sea-ice variability archived in coralline algal barium

Accelerated warming and melting of Arctic sea-ice has been associated with significant increases in phytoplankton productivity in recent years. Here, utilizing a multiproxy approach, we reconstruct an annually resolved record of Labrador Sea productivity related to sea-ice variability in Labrador, Canada that extends well into the Little Ice Age (LIA; 1646 AD). Barium-to-calcium ratios (Ba/Ca) ...

Simultaneous Retrieval of Sea Surface Wind Speed and Sea Surface Temperature from a Multi-frequency Scanning Microwave Radiometer

Derivation of geophysical parameters from satellite measured brightness-temperature (TB) is an important aspect of satellite remote sensing. Primarily, this involves development of complex inversion algorithms and empirical relations comprising TB and in situ data for parameter retrieval and algorithm validation. In the present work, an Artificial Neural Network model has been attempted to simu...

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
