The techniques utilized to extract chlorophyll from plant materials are destructive and based on methods that use organic solvents. This study proposes the non-destructive quantification of chlorophyll and nitrogen concentration using a portable chlorophyll meter (SPAD-502). Further, was possible to establish relationships between chlorophyll fluorescence and SPAD-502 values. This methodology c...

The relationship between the carotenoid zeaxanthin, formed by violaxanthin de-epoxidation, and nonphotochemical fluorescence quenching (q(NP)) in the light was investigated in leaves of Glycine max during a transient from dark to light in 2% O(2), 0% CO(2) at 100 to 200 micromoles of photons per square meter per second. (a) Up to a q(NP) (which can vary between 0 and 1) of about 0.7, the zeaxan...

Atari 2600 Assault is a game environment provided on the OpenAI Gym platform; it is a top-down shoot’em up game where the player gains reward points for destroying enemy ships. The enemy consists of a mothership and smaller vessels that shoot at the player. The player can move and shoot in various directions with a total of 7 actions available. Every time the player shoots, a heat meter keeps t...

Unprecedented high volumes of data are becoming available with the growth of the advanced metering infrastructure. These are expected to benefit planning and operation of the future power system, and to help the customers transition from a passive to an active role. In this paper, we explore for the first time in the smart grid context the benefits of using Deep Reinforcement Learning, a hybrid...

The concept of photonic frequency $(\omega)$ - momentum $(q)$ dispersion has been extensively studied in artificial dielectric structures such as crystals and metamaterials. However, the $\omega-q$ electrodynamic excitations hosted natural materials at atomistic level is far less explored. Here, we develop a Maxwell Hamiltonian theory matter combined with quantum polarization to obtain interact...
