First measurement of muon-neutrino disappearance in NOvA

Abstract: This paper reports the first measurement using the NOvA detectors of νμ disappearance in a νμ beam. The analysis uses a 14 kton-equivalent exposure of 2.74×1020 protons-on-target from the Fermilab NuMI beam. Assuming the normal neutrino mass hierarchy, we measure Δm232=(2.52+0.20−0.18)×10−3 eV2 and sin2θ23 in the range 0.38–0.65, both at the 68% confidence level, with two statistically degenerate best-fit points at sin2θ23=0.43 and 0.60. Results for the inverted mass hierarchy are also presented.

Review on the numerical investigations into the design and development of Savonius wind rotors

Abstract: In recent era, research and development activities in the field of renewable energy, especially wind and solar, have been considerably increased, due to the worldwide energy crisis and high global emission However, the available technical designs are not yet adequate to develop a reliable distributed wind energy converter for low wind speed conditions The Savonius rotor appears to be particularly promising for such conditions, but suffers from a low efficiency Till now, a number of experimentations have been carried out in the area of Savonius rotor to increase its efficiency These large-scale experimentations involve massive costs and hazards In this context, computational studies have shown a significant importance to carry out the research with large number of physical designs and parameters Over the past four decades, investigations have been carried out with various computational methodologies and turbulence models to optimize the different parameters and hence the efficiency of these rotors In the present paper, a detailed review of various computational methods addressing the influence of various operating parameters and augmentation techniques has been reported From this review study, it is observed that with the selection of a proper computational methodology, the design, performance, and efficiency of a Savonius rotor can be enhanced significantly
