Co-production of active char and hydrogen from Algerian Date Palm Spikelet: Mass and energy balance based on experimental data

The industrial deployment of green hydrogen production via biomass gasification is still constrained by high feedstock costs and process complexity. In particular, tar formation in the syngas requires costly gas-cleaning operations and reduces the lifetime of hydrogen separation...

Deep Learning Benchmarks for Multi-Step Photovoltaic Power Forecasting: Comparative Assessment of GRU, LSTM, and BiLSTM Architectures

Accurate photovoltaic (PV) power forecasting is essential for renewable energy integration, dynamic reserve allocation, and generation scheduling. Unpredicted generation ramps induce substantial voltage and frequency deviations on grid-connected distribution networks. This paper...

Global Dynamics and Complete Phase Portrait Classification of a Nonlinear SIRS Model with Saturated Incidence

This paper investigates the global dynamics of a nonlinear Susceptible–Infective–Recovered–Susceptible (SIRS) epidemic model with a nonmonotonic saturated incidence rate. By reducing the model to a planar cubic polynomial differential system, we perform a complete qualitative ana...
