Optimization and plasticity in disordered media [PDF]
, 2009 We study the plastic yielding of disordered media using the perfectly plastic random fuse model. The yield surfaces are shown to be different from those obtained minimizing the sum of the local yield thresholds, i.e.

Optimization of hhv and energy yield from torrefaction of Albizia zygia wood- calcium hydrogen phosphate catalyst blends using optimal combined design [PDF]
Acta Periodica Technologica, 2022 The over-reliance on fossil fuels as a primary source of energy is partly responsible for the increase in carbon dioxide (CO2), depletion of the ozone layer, and general environmental pollution.

Absolute measurement of the nitrogen fluorescence yield in air between 300 and 430 nm [PDF]
, 2007 The nitrogen fluorescence induced in air is used to detect ultra-high energy cosmic rays and to measure their energy. The precise knowledge of the absolute fluorescence yield is the key quantity to improve the accuracy on the cosmic ray energy. The total
