Design and economic analysis of an off-grid solar PV in Jos-Nigeria [PDF]

open access: yes, 2020
Around the globe, renewable energy sources and their associated technologies are critical to power generation. The solar photovoltaic (PV) system is one of the renewable energy systems supporting electricity consumption in the residential domain. Despite

Design of Standalone Micro-Grid Systems Using Teaching Learning Based Optimization

open access: yesAlgerian Journal of Signals and Systems, 2017
Meeting the load demand reliably and efficiently is the most important issue of any electrical system. Installing huge off grid hybrid power systems to deliver enough power is economically unwise.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

SpectralConway: Cellular Automata Off The Grid [PDF]

open access: yes, 2010
SpectralConway is a spectral implementation of cellular automata (CA), specifically John Conway's Game of Life (GoL). The process eschews the traditional quantised grid paradigm of the CA in favour of a frequency continuum.

Off-Grid Power Management

open access: yes, 2019
There are many people who would benefit from having electricity but who live too far from an electrical grid to access it. Recent developments can help such people. Solar-generated electricity and battery storage are now available at a very reasonable cost for those who want to have an electrical system in their home or business.

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...
