Modelling, iterative procedure and simulation results for a monocrystalline solar cell [PDF]

open access: yes, 2012
This paper focuses on the modelling and simulation for a photovoltaic system formed by monocrystalline solar modules. The objective is to find the parameters of the nonlinear I-V equation by adjusting the curve at three points: open circuit, maximum ...

Numerical simulation of turbulent duct flows with constant power input [PDF]

open access: yes, 2014
The numerical simulation of a flow through a duct requires an externally specified forcing that makes the fluid flow against viscous friction. To this aim, it is customary to enforce a constant value for either the flow rate (CFR) or the pressure ...

Efficient modeling of the wireless power transfer efficiency for varying positions and orientations between transmitter and receiver [PDF]

open access: yes, 2015
A method that efficiently calculates the Power Transfer Efficiency (PTE) of a Wireless Power Transfer (WPT) system is described in this paper. It allows for arbitrary relative positions and orientations between devices in the system, both in far-field ...

Integrating power flow modelling with building simulation [PDF]

open access: yes, 2001
The inclusion of photovoltaic facades and other local sources of both heat and power within building designs has given rise to the concept of embedded generation: where some or all of the heat and power demands are produced close to the point of use ...

Analysis and Design of Adaptive OCDMA Passive Optical Networks

open access: yes, 2016
OCDMA systems can support multiple classes of service by differentiating code parameters, power level and diversity order. In this paper, we analyze BER performance of a multi-class 1D/2D OCDMA system and propose a new approximation method that can be ...
