Simulated dark matter profiles are often modelled as a ‘NFW’ density profile rather than a single power law. Recently, attention has turned to the rather rigorous power-law behaviour exhibited by the ‘pseudo phase-space density’ of the dark matter halo, which is defined dimensionally in terms of the local density and velocity dispersion of the dark matter particles. The non-power-law behaviour ...

Abstract In this work, a comparative study of hybrid solar cells based on P3HT and TiO2 nanofibers was accomplished. Electrospinning, a low cost production method for large area nanofibrous films, was employed to fabricate the organic-inorganic hybrid solar cells based on poly (3-hexylthiophene) and TiO2 nanofibers. The performance of the hybrid solar cells was analyzed for four density levels ...

Optimization of process parameter is one of the ideal goals in laser sintering. The results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. In this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...

The infrasound levels due to the blade-tower interaction generated by a wind turbine in publication Pilger and Ceranna (JSV, Vol. 388, pp. 188-200, 2017) have be corrected interpreted as sound pressure level. Also, electrical power of should for high case 660 kW. We provide reanalysis measured data with spectrum showing low-frequency signal about 34 dB below original work. All at distance 200 m...

Microphotosynthetic Power Cells ( μ PSCs) have emerged as a promising bioelectricity generation technology with the potential to meet low-power application demand in sustainable, and environmentally friendly manner by leveraging photosynthetic capabilities of autotrophs. Internal losses connected transfer charges from organisms electron acceptor (anode electrode), however, continue pose serious...

Electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. The critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. Switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gea...
