Performance of piezoelectric energy harvester with vortex-
induced vibration and various bluff bodies
Piezoelectric energy harvesters (PEHs) are a kind of energy harvester that
generates electricity due to pressure or vibration. Vortex-induced vibration
(VIV) is a method that utilized wind energy and bluff body to generate the
vibration in PEH.…

One to many (new scheme for symmetric cryptography)
Symmetric cryptography will always produce the same ciphertext if the plaintext and the
given key are the same repeatedly. This condition will make it easier for cryptanalysts
to perform cryptanalysis. This research introduces a one-to-many…

Stability by assigning structures by applying the multivariable subspace identification algorithm for a wind system with a DFIG
In this paper, a controller for a doubly fed induction generator (DFIG)
connected to a wind system is proposed. This control assigning its own
structures as an optimal control method, the electric model in the DFIG state
space is also shown, for…
