Pengenalan Nada Piano Dengan Algoritma Short Time Fourier Transform (STFT)

open access: yesJurnal Nasional Teknologi Informasi dan Aplikasnya
In the field of music, sheet music notation represents the graphical representation of the melody or harmony of a song. However, manually transcribing complex piano music can be challenging. In this research, we propose the application of Short-Time Fourier Transform (STFT) as a method for piano note recognition. STFT, a spectral analysis technique, is

Designing Wire Mazes for Replicating Natural Echoes to Study Bat Biosonar Function

open access: yesAdvanced Intelligent Systems, EarlyView.
A validated framework combining efficient physical modeling (multiple scattering model) and deep learning is presented to guide wire‐maze design for bat biosonar studies. This approach rapidly generates large datasets to test acoustic distinguishability among wire arrangements.

Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...

Gamma suppression correlates with thalamic stimulation therapeutic response in intractable epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective In patients with drug‐resistant epilepsy who undergo anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS), efficacy is assessed months after therapy initiation and clinicians have no guidance when choosing stimulation parameters due to the lack of real‐time biomarkers.

Vibration Characteristics of Corn Combine Harvester with the Time-Varying Mass System under Non-Stationary Random Vibration

open access: yesAgriculture, 2022
In field harvesting conditions, the non-stationary random vibration characteristics of the harvester are rarely considered, and the results of vibration frequency calculated by different time–frequency transformation methods are different. In this paper,

Variance‐Empirical Mode Decomposition Method for Fault Detection in MMC‐HVDC Transmission Lines

open access: yesEnergy Science &Engineering, EarlyView.
A variance‐embedded empirical mode decomposition (VEMD) method is proposed for fast and accurate fault detection in MMC‐HVDC transmission lines. By combining variance analysis with EMD, the method reliably detects various faults without communication links and remains robust to noise and non‐fault transients.

Vocal Outcomes After Cell‐Based Outer Vocal Fold Implant in Porcine Bilateral Vocal Fold Resection

open access: yesThe Laryngoscope, EarlyView.
Cell‐based outer vocal fold replacement (COVR) was evaluated in a porcine model of bilateral vocal fold injury using longitudinal acoustic analysis and histologic assessment. COVR implantation resulted in recovery of the nonperiodic acoustic parameter Q50 to preoperative levels by 6 months, with implanted human adipose‐derived stem cells detected in 7 ...

Fault Diagnosis in an Induction‐Motor‐Driven Rotating Machinery Test Rig Under Unseen Operating Loads Using Multimodal Fusion and Multiagent Deep Reinforcement Learning

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Conventional fault‐diagnosis methods, largely grounded in one‐dimensional signal analysis and linear modeling, often fail to detect complex nonlinear faults in rotating machinery operating under variable loads. Data‐driven approaches also face challenges in extracting discriminative information from high‐dimensional multisensor measurements ...
