A spar buoy design for oceanographic data telemetry

Oceanographic Buoy Expands OBSEA Capabilities

On this paper, the electronic system and oceanographic instruments of a moored buoy are presented. The system has been designed by the SARTI research team to meet a very specific objective, which is to expand the capabilities of the underwater observatory OBSEA as a research and test platform, providing an infrastructure for testing instruments either at the seafloor or at the surface. The syst...

Acoustic Oceanographic Buoy testing during the MREA’03 sea trial

This paper proposes an innovative concept that responds to the requirements of acoustic REA as the integration between a network of sophisticated Acoustic-Oceanographic Buoys (AOB) and online ocean properties inversion algorithms. A prototype of the system, including one sonobuoy and a preliminary version of the inversion code, was tested at sea during the MREA’03 sea trial. The AOB is a light ...

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...

Experimental and Numerical Study of Spar Buoy-magnet/spring Oscillators Used as Wave Energy Absorbers

We study free-floating point absorption wave generators, consisting of an assemblage of one or a few (mostly heaving) spar buoys, housing at least one short-stroke linear generator (SSLG), made of a magnet, suspended to a spring, and oscillating within a coil. This system is aimed at producing low and renewable wave power (up to kW) for marine coastal surveillance systems. Both scale model expe...
