WindChain: Physics-Constrained Blockchain Attestation of Wind-Resource Provenance for Verifiable Renewable Energy Certificates in Smart Cities

Smart-city energy platforms—peer-to-peer markets and tokenized renewable energy certificates—settle against metered generation, yet never check the physical plausibility of those claims. For wind, attainable energy is not measured but derived from anemometry through a vertical ex...

Discrete Riccati and Comparison Approaches to Oscillation of Second-Order Advanced Difference Equations with Multiple Deviating Arguments

In this work, we develop, from first principles, a discrete oscillation theory for second-order nonlinear advanced difference equations with several deviating arguments, Δr(n)(Δy(n))α+∑i=1mqi(n)Fy(σi(n))=0,σi(n)≥n, studied under the canonical condition ∑s=n0∞r−1/α(s)=∞. This equa...
