Fluid Dynamics & Propulsion
Note In our demonstrations, we tune TRNS to achieve the best overall balance between noise reduction and preservation of real-world signal dynamics, rather than pursuing the absolute highest RMS number possible.
While TRNS parameters can be adjusted to reach higher RMS reductions (sometimes comparable to advanced machine learning methods), we intentionally prioritize practical performance. Excessive denoising frequently leads to oversmoothing, which can remove important physical transients, degradation trends, or operational signatures critical for real applications such as fault detection, predictive maintenance, and process control.
TRNS is designed to deliver strong, usable results that respect the underlying physics of the system.

Infusion Pump Rate Denoising with TRNS Real-World Smart Infusion Pump Signal Enhancement Demonstration
Dataset Provenance
The dataset used in this demonstration is from the VitalDB high-fidelity multi-parameter vital signs database, publicly available on PhysioNet. Specifically, we used Case 16 (perioperative surgical patient) and the track Orchestra/PPF20_RATE (real smart infusion pump delivery rate).Description
VitalDB contains real intraoperative vital signs and device data collected from surgical patients. The infusion pump rate signal includes clinically important features such as steady delivery rates, bolus events, and step changes, contaminated by sensor noise, quantization effects, and delivery irregularities typical of smart infusion pumps.
The raw infusion pump flow rate signal was selected because it contains critical therapeutic delivery information mixed with real-world noise — conditions representative of challenges in accurate drug administration, occlusion detection, under-infusion alerts, and overall patient safety in hospital settings.
Denoised with TRNS

Performance Comparison

Why TRNS Numbers Are Superior in Practice
TRNS achieves a strong 1.89× noise reduction while respecting the underlying mechanics of infusion pump delivery. This makes it particularly valuable for real-time processing in smart infusion pumps, where preserving accurate delivery rates, bolus peaks, and detecting clinically dangerous conditions (occlusions, free-flow, under-delivery) is critical for patient safety.
In our demonstrations, we tune TRNS to achieve the best overall balance between noise reduction and preservation of real-world delivery dynamics, rather than pursuing the absolute highest RMS number possible.
While TRNS parameters can be adjusted to reach higher RMS reductions, we intentionally prioritize practical performance. Excessive denoising frequently leads to oversmoothing, which can mask important flow variations or bolus events critical for safe medication administration.
TRNS is designed to deliver strong, usable results that respect the underlying physics and clinical requirements of infusion therapy systems.

Why TRNS Numbers Are Superior in Practice
TRNS achieves a strong 2.51× RMS noise reduction while respecting the underlying Poisson statistics of single-photon detection. This makes it particularly valuable for quantum photonics applications, where preserving sharp transient photon bursts is critical for accurate timing, lifetime estimation, and single-molecule detection.
In our demonstrations, we tune TRNS to achieve the best overall balance between noise reduction and preservation of real-world photon arrival features, rather than pursuing the absolute highest RMS number possible.
While TRNS parameters can be adjusted to reach higher RMS reductions, we intentionally prioritize practical performance. Excessive denoising frequently leads to oversmoothing, which can remove important photon bursts critical for quantum sensing and imaging applications.
TRNS is designed to deliver strong, usable results that respect the underlying quantum statistics of the signal.

Geothermal Monitoring with TRNS Bottomhole Temperature Denoising Demonstration (Stanford Thermal Earth Model)
Dataset Provenance
The dataset used in this demonstration is from the Stanford Thermal Earth Model for the Conterminous United States, publicly available through the Geothermal Data Repository (DOI: 10.15121/2324793).Description
This dataset contains aggregated bottomhole temperature measurements across the United States, including location, depth, state, source, and temperature values. A physics-informed graph neural network was used to develop national temperature-at-depth maps. The raw data includes significant measurement noise and spatial variability typical of geothermal well data.
For this embodiment, the data was sorted by depth to create more coherent vertical temperature profiles before applying TRNS. This preprocessing step transforms the aggregated spatial dataset into structured depth-ordered sequences that better represent geothermal gradients and allow more effective denoising while preserving meaningful geological trends.

Featured Datasets
NASA Commercial Modular Aero-Propulsion System Simulation (C-MAPSS) Turbofan Engine Degradation Simulation Dataset, FD004 Subset
Data Provenance
The dataset used in this demonstration is the FD004 subset of the NASA Commercial Modular Aero-Propulsion System Simulation (C-MAPSS) Turbofan Engine Degradation Simulation Dataset.Description
FD004 is the most complex and realistic subset, combining six operating conditions with two simultaneous fault modes (High-Pressure Compressor + Fan degradation). It contains 248–249 training trajectories and represents the highest level of difficulty in the CMAPSS suite.
Sensor 12 (HPC Outlet Pressure) was selected because it is highly responsive to both fault modes across varying flight conditions. This subset most closely mirrors real-world commercial turbofan engine operation, where engines experience changing environmental and load conditions while potentially developing multiple faults.
FD004 serves as the ultimate benchmark for evaluating the robustness, generalization, and practical applicability of denoising algorithms in aerospace propulsion systems.

Performance Comparison

Performance ranges shown are typical values reported in literature and industry benchmarks for each method. Actual results vary by application and implementation.
Why TRNS Numbers Are Superior in Practice
TRNS achieves exceptional 11.94× noise reduction while maintaining the critical long-term degradation trends needed for accurate Remaining Useful Life (RUL) prediction. In the highly challenging FD004 environment — with 6 operating conditions and 2 simultaneous fault modes — TRNS demonstrates strong generalization without oversmoothing important engine behavior.
Unlike many hybrid and deep learning approaches that can achieve high RMS numbers but often lose meaningful degradation signals, TRNS delivers a balanced, physics-based solution that preserves the operational dynamics essential for reliable prognostics in real-world multi-regime turbofan engine applications.
