Opis:
Solar cells are photovoltaic devices that convert sun energy directly into the electrical energy. Solar panel is composed of multiple solar cells that are combined together. Depending on the power demand, solar panels are connected to each other in series or parallel. Thus, electrical energy from the solar array systems is created to meet the needs. Solar panels are used on roof and wall systems in buildings and power plants. In solar array design, radiance, temperature, shading, surface angle and effect of series-parallel connection, which are factors affecting the operation of solar panels, should be considered. Shading significantly reduces the efficiency of a solar array system. Shading can occur entirely or partially due to dynamic or static obstacles. The effect of shading varies by location at which the solar panel is formed. In this work, design and optimization of solar arrays, positioned over a large area, having different time constant shading effects, was performed in order to minimize shading effect.

Opis:
Quantum Fisher information has recently been an essential tool for analyzing the phase sensitivity of the quantum states in various quantum tasks, requiring high precision, such as quantum clock synchronization, positioning and many applications which include quantum interferometers. Due to the interactions with the environment, all quantum systems are subject to various decoherence effects. Therefore the research on quantum Fisher information under decoherence has been recently attracting more attention. In this work, analyzing the quantum Fisher information, we study the phase sensitivity of bipartite quantum correlations, in particular four Bell pairs amplitude damping channels. For a specific Bell state we arrive at similar results of Greenberger-Horne-Zeilinger (GHZ) states (as expected). For the other three Bell states, we present our results which point the interesting behavior of quantum Fisher information with respect to the decoherence rate. We also find the regions where the quantum Fisher information exhibits discontinuities.

Opis:
We reformulate the Rutherford scattering of alpha particle for a head on collision, taking into account the rest mass variation of the particle, as implied by the energy conservation law. Our relativistic reformulation (which includes the energy conservation) constitutes a new example for the breakdown of the Lorentz invariance. Briefly speaking, even at rest or during the whole scattering process, the distance between the alpha particle and the gold nucleus is not invariant but depends on the frame of the observer attached to either object. According to our relativistic reformulation, we also provide a new set of Lorentz transformations.

Opis:
In order to create polarization based entanglement networks of W₄ state, we propose an optical setup, which uses only four horizontally polarized photons as resource which implies no entanglement requirement as a resource. This setup can generate target state deterministically, by operating several quantum optical gates, which can be realized with current photonics technology. The setup we propose is composed of one Not, two Hadamard, five Controlled Not (CNot) and one Toffoli gate.

Opis:
We study the quantum Fisher information (QFI) of W states and W-like states under decoherence. In particular, we find that on the contrary to amplitude damping and depolarizing decoherence, a W-like state of 3 qubits obtained by discarding 1 qubit of a genuine W state of 4 qubits is more robust than a genuine W state of 3 qubits under amplitude amplifying and phase damping decoherence.
