Abstract: Aerodynamics and motion performance of the floating vertical wind turbine (VAWT) were studied in this paper, where the wind turbine was H-type and the floating foundation was truss spar type. Based on the double-multiple-stream-tube theory, the formulae were deduced to calculate the aerodynamic loads acting on the wind turbine considering the motions of the floating foundation. The su...

Ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. A number of algorithms such as floating or moving cone method, floating cone method II and the corrected forms of this method, the Korobov algorithm and the corrected form of this method, dynamic programming and the Lerchs and Grossmann algorithm based on grap...

A programming technique for controlling the floating gates (FG) in ultra low-voltage (ULV) floating-gate circuits is presented. Simple ultra low-voltage floatinggate current scaling and level shifting circuits are discussed. The current scaling and level shifting are accomplished using only minimum sized transistors and floating capacitors. Floating-gate current multiplier and divider circuits ...

determining the responses of floating structures at sea are the most important concerns in shipbuilding industry. in physical and dynamical principles a ship can be analyzed as a free elastic beam floating in sea without any supports. the analysis of corresponding dynamic equations are difficult and time- consuming, thus investigation on the behavior of floating structures can be done numerical...

‘~Ridan-gil’ is a similarly named commercial streets which has developed into brand through social media. Though it one of the benchmarking elements street revitalization projects, such are indeed declining due to gentrification. Accordingly, purpose this study identify factors that affect property price side in Seoul. As methodology, conducted multiple regression analysis on physical and deter...

GOALS Low-power systems often find the power cost of floating-point hardware prohibitively expensive. This research explores ways of reducing floating-point power consumption by minimizing the bitwidth representation of floating-point data. Analysis of several floating point programs that manipulate low-resolution human sensory data shows that these programs suffer no loss of accuracy even with...

The purpose of the present study was to develop an optimized gastric floating drug delivery system (GFDDS) containing domperidone as a model drug. Box-Behnken design was employed in formulating the GFDDS with three polymers: hydroxypropyl methylcellulose K4M (HPMC K4M) (X1), Carbopol 934P (X2) and sodium alginate (X3), as independent variables. Floating lag time (FLT), total floating time (TFT)...

The price dispersion means different prices for same goods. In the Internet economy, many economists reckon that the price dispersion in the e-commerce markets should descend along with the dropping of search cost. However, the correlative empirical studies reach a contrary opinion: there not only exist price dispersion in the e-commerce market, but also has larger dispersion degree than the tr...
