Methane
Core prediction target
GFIS remains centred on methane-yield prediction. Total-biogas datasets are identified separately and are never relabelled as methane.
One project, two intelligence levels, one evidence chain
Level 1 plans biogas infrastructure across villages, districts and states. Level 2 predicts methane yield, estimates stability, tests operating scenarios and records evidence for each plant. Version 3 explains how these layers connect without hiding the model behind a dashboard.
Level 1 planning context
Measured and public data
Physics-guided neural engine
Reactor simulation & decisions
Evidence, memory & feedback
VFA/ALK
Stability soft sensor
The system exposes the estimated ratio, thresholds, state classification and the future calibration route—rather than returning an unexplained alarm.
48 h
Stateful simulator horizon
Scenario inputs propagate through methane, stability and physics-bound outputs with memory and exportable action/effect records.
Explore the evidence as connected chapters
The former single report is now a navigable website package. Each chapter states what is implemented, what was executed, what data supports it, and what remains to be externally validated.
Transparent method
Inputs, feature engineering, model branches, equations, physical feasibility, soft sensing and decision logic.
Open methodActual data and training
Evaluator-suggested public data, leakage-safe chronology, rolling folds, epochs, checkpoints and architecture decision.
Open trainingFull-scale industrial evidence
500,400 one-minute Muscatine WRRF SCADA records, provenance, quality audit, target boundary and plant-twin integration.
Open industrial evidenceWorking simulator
Executed 48-hour traces, Control Room, scenario handoff, VFA/ALK warnings, physics-bound trigger and run memory.
Open simulator evidenceEvaluator guidance and response
The original black-box concern, actions taken, evidence produced and remaining final-phase work appear as an HTML chapter.
Open responseConnected 3D virtual plant
A software-in-the-loop anaerobic-digestion plant whose equipment, telemetry, alarms and 3D state are driven by GFIS.
Open plant architectureSeparate gasification prototype
An interactive high-temperature thermochemical mass/energy calculator kept outside the anaerobic digester, with visible assumptions and outputs.
Open gasification moduleGFIS 30+ national infrastructure
Satellite and waste intelligence, plant siting, hubs, gas/energy networks, hierarchical control rooms, economics and 30-year expansion.
Open GFIS 30+Reproducible artifact library
CSV outputs, epoch histories, split and run manifests, screenshots, model evidence and retained Version 2.
Open retained reportEvidence labels prevent overclaiming
Implemented
Executable source exists
The capability is present in Python, API or browser code and can be inspected directly.
Controlled demonstration
Scenario evidence exists
GFIS executed the capability on synthetic or controlled stress inputs. This proves function, not plant accuracy.
External evaluation
Independent data tested
Measured public observations are evaluated chronologically with provenance, checksums and limitations.
Scientific rule: a visually working simulator is product evidence; a leakage-safe evaluation on measured data is validation evidence. GFIS reports both, but never treats them as identical.
