Analisis Kinerja Kompresi Citra Digital dengan Komparasi DWT, DCT dan Hybrid (DWT-DCT)
Penelitian ini merupakan penelitian tentang penerapan transformasi diskrit kosinus (DCT), transformasi wavelet diskrit (DWT), dan hybrid sebagai penggabungan dari kedua transformasi sebelumnya dalam proses kompresi data citra digital. Proses kompresi dilakukan untuk menekan konsumsi sumber daya memory, mempercepat proses transmisi citra digital. Proses

The Smoluchowski-Kramers limit of stochastic differential equations with arbitrary state-dependent friction [PDF]
We study a class of systems of stochastic differential equations describing diffusive phenomena. The Smoluchowski-Kramers approximation is used to describe their dynamics in the small mass limit.

A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.
