Fuzzy Logic Controller Application for an Active Two-Axis Solar Tracking System [PDF]

E3S Web of Conferences, 2020
The changes in the intensity of solar radiation cause the electrical power produced by solar panels to be not optimal. The solar panel position control system to the position of the solar is an effort to overcome this problem.

Characterisation of the electromagnetic component in ultra-high energy inclined air showers [PDF]

, 2009
Inclined air showers - those arriving at ground with zenith angle with respect to the vertical theta > 60 deg - are characterised by the dominance of the muonic component at ground which is accompanied by an electromagnetic halo produced mainly by muon ...

Performance improvement of two-axis solar tracking system by using flat-mirror reflectors

Energy Reports, 2020
This work studied the performance improvement of a two-axis solar tracking system by using flat-mirror reflectors. The two- and four-sided flat-mirror reflectors were set on the solar panel with angles of 90°, 120°, and 150° between the panel and flat ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Q^2 Evolution of the Neutron Spin Structure Moments using a He-3 Target

, 2003
We have measured the spin structure functions $g_1$ and $g_2$ of $^3$He in a double-spin experiment by inclusively scattering polarized electrons at energies ranging from 0.862 to 5.07 GeV off a polarized $^3$He target at a 15.5$^{\circ}$ scattering ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
