Generating Electricity from the renewable resources, especially from wind, within the urban regions, is of much concern for many researchers. The rotor of Savonious has a great potential of electricity generating for the urban regions and domestic applications. In this paper, influence of the Overlap ratio on the performance of the Savonious rotor is investigated. For this purpose, the numerica...

The gravitational water vortex turbine is a system that can convert the energy from artificial by means of drained through basin outlet to kinetic rotor rotation. This type able produce despite low head flow. Many researches were conducted improve efficiency this changing shape basin, or rotor. Meanwhile, Savonius has good starting rotation and ease fabrication, but efficiency. One way increase...

The Ocean has provided a new avenue in the quest for renewable energy. One potentialsource of energy is marine current, which is harnessed using either vertical or horizontal axis turbines.This paper describes a particular type of vertical axis turbine which is suitable for low current velocityapplications. The simulation of Savonius-type turbine, which hitherto has never been proposed formarin...

Overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA), was first defined by Flenley. Although it can refer to concomitant occurrence of any of the pulmonary diseases and OSA, overlap syndrome is commonly considered as the coexistence of OSA and COPD. This disease has unique adverse health consequences distinct from ...

Vietnamese word segmentation (VWS) is a challenging basic issue for natural language processing. This paper addresses the problem of how does dictionary size influence VWS performance, proposes two novel measures: square overlap ratio (SOR) and relaxed square overlap ratio (RSOR), and validates their effectiveness. The SOR measure is the product of dictionary overlap ratio and corpus overlap ra...

We studied the spatial overlap of on and off subregions in macaque primary visual cortex and its relation to the response modulation ratio (the F1/F0 ratio). Spatial maps of on and off subregions were obtained by reverse correlation with a dynamic noise pattern of bright and dark spots. Two spatial maps, on and off, were produced by cross-correlating the spike train with the location of bright ...
