A study of the Dirichlet Priors for term frequency normalisation [PDF]
, 2005 In Information Retrieval (IR), the Dirichlet Priors have been applied to the smoothing technique of the language modeling approach. In this paper, we apply the Dirichlet Priors to the term frequency normalisation of the classical BM25 probabilistic model

System-Level Model and Simulation of a Frequency-Tunable Vibration Energy Harvester
Micromachines, 2020 In this paper, we present a macroscale multiresonant vibration-based energy harvester. The device features frequency tunability through magnetostatic actuation on the resonator. The magnetic tuning scheme uses external magnets on linear stages.

Tuning-Range Extension Strategies for Varactor-Based Frequency-Reconfigurable Antennas
IEEE Open Journal of Antennas and Propagation, 2023 Tuning range extension strategies for varactor-based frequency-reconfigurable planar patch antennas are presented. The three tuning range optimization methods described in the paper include co-optimization of antenna dimensions and varactor properties ...
