Confounding factor analysis for vocal fold oscillations
(MDPI, 2023)
This paper provides a methodology to better understand the relationships between different aspects of vocal fold motion, which are used as features in machine learning-based approaches for detecting respiratory infections ...
Orthogonal frequency division multiplexing with subcarrier gap modulation
(IEEE 31st PIMRC'20 - Workshop on Waveform Design for Beyond 5G Communications, 2020)
A new modulation scheme called orthogonal frequency division multiplexing with subcarrier gap modulation (OFDM-SGM) is proposed. The proposed scheme embeds extra information bits by exploiting the gap between the active ...
A belt-integrated piezoelectric energy harvester for wearable electronic devices
(Ferroelectrics, 2021)
This paper reports a novel piezoelectric energy harvester incorporated on a waistbelt for power generation from waist movements. The device is composed of multiple piezoelectric disks in 3 D-printed encapsulations and ...
Broadly tunable two-color lasing of Cr:LiCAF with on-surface and off-surface optical axis birefringent filters: performance comparison
(Applied Optics, 2022)
We studied the two-color lasing performance of a Cr:LiCAF laser using crystal quartz on-surface and off-surface optical axis birefringent filters (BRFs). Four different on-surface optical axis BRFs with thicknesses of 2 ...
Physical layer security against eavesdropping in the internet of drones (IoD) based communication systems
(2019)
rones or unmanned aerial vehicles (UAVs) communication technology, which has recently been
thoroughly studied and adopted by 3GPP standard (Release 15) due to its dynamic, flexible, and flying
nature, is expected to be ...
A compact energy transducer for power generation from respiration
(Journal of Microelectromechanical Systems, 2019)
This paper reports a compact magnetic transducer developed for generating electrical power from respiration. The device incorporates a side-drive turbine rotor with embedded permanent magnets and two stators, integrated ...
Secure and reliable IoT communications using nonorthogonal signals’ superposition with dual-transmission
(IEEE 31st PIMRC'20 - Workshop on 5G Mobile Communication System for Smart Factories, 2020)
Ensuring secure communication for internet of
things (IoT) has drawn much attention because of the lim itation in the use of conventional cryptographic techniques
owing to the unique features of IoT devices such as ...
Orthogonal frequency division multiplexing with subcarrier power modulation for doubling the spectral efficiency of 6G and beyond networks
(Transactions on Emerging Telecommunications Technologies, 2020)
With the emergence of new applications (eg, extended reality [XR] and haptics), which require to be simultaneously served not just with low latency and sufficient reliability, but also with high spectral efficiency, future ...
Is cell-free massive MIMO (CF-MMIMO) equivalent to the already existing and commercialized pCell technology?
(2021)
Distributed antenna system (DAS) is a highly diversified concept that can help lower radiated power, maximize coverage, and improve spectral efficiency. Yet, the most exciting feature of DAS is the distribution of remote ...
Optimization of hydrothermal synthesis of Ce3+ co-doped NaYF4, Yb3+, Er3+upconversion nanoparticles and investigation of their size, morphology, and phase transitions.
(ICENS, 2019)
In this study, the synthesis of water-soluble polyethyleneimine (PEI) modified UCNPs which were prepared by a hydrothermal method have been reported. The resultant UCNPs were small size and hexagonal β-phase structure ...
