This paper aims at summarizing various methods used for representing and estimating the power coefficient in wind turbines, such as exponential, sinusoidal and polynomial models, as 6-0 igora vibrance well as mathematical tools known as state observers.We present an exhaustive bibliographic review of the models used to calculate the power coefficie
The relevance of the research topic is due to the need for scientific and technological support for the development of the Arctic, which, in turn, will require a sufficient number of qualified personnel.The purpose of the work is to assess how currently the Russian Arctic is ready to meet the challenges of import substitution and the complication o
Abstract This paper presents a review of current techniques employed for dynamic analysis of concrete gravity dams under seismic action.Traditional procedures applied in offworld drum pads design bureaus, such as the Pseudo-Static method, often neglect structural dynamic properties, as well as ground amplification effects.A practical alternative ar
An acoustic sea glider has been developed for ambient sea noise measurement and target detection through the deployment of an acoustic vector sensor (AVS).The glider was designed with three cabins connected in sequence and it can dive to depths exceeding 1200m.The AVS fixed on the glider measure acoustic pressure and particle velocities related to
