We present VA-HMA, a volatility-aware hybrid memory architecture that combines DRAM and Non-Volatile Memory (NVM) with a lightweight, machine-learned placement layer and endurance-aware fault tolerance. VA-HMA continuously monitors access patterns and applies a Random Forest–based predictor to guide batched page migrations and … …Journal of Computer Science, Vol. 22, Issue 6 · 27 Jun 2026 · 1,214 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAbout Aircraft's New Power and PropulsionRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuEven though the current classical methods of aerospace propulsion are much improved, some of the most modern methods have already been introduced, including propulsion with electric motors. Energy can be obtained from hydrogen burners, honeycomb burners to protect the combustion of hydrogen that burns 10 times faster than conventional fuels or alcohols. Hydrogen storage is also done in honeycomb cell … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 5 Mar 2020 · 7,325 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordThermal Energy Storage in the Ground of a Greenhouse by the Polypropylene Capillary Heat ExchangerM. Lazâar, S. Koôli, M. Hazami et al.The problem of temperature inversion is one of solar origin principal problems about which the cultures under shelters complain. Indeed, for the winter period, the temperature under greenhouse is very low at night and it is rather high during the day in summer. Consequently, the heating of the greenhouses is essential. In this work, we studied the advisability of using … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,939 accessesView PDFCite

Guizani, A. BelghithWe present an analysis of the melting process in Phase Change Materials (PCM) in a horizontal cavity heated from below, driven by the coupling of transient heat conduction in the solid phase and steady state laminar natural convection in the liquid phase with one of the boundaries of the solution domain that moves. We state the problem in the Cartesian … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,391 accessesView PDFCite
