PICALLW · TECHNOLOGY & RESEARCH

We build technology.
We test hypotheses.

PICALLW connects software engineering with research into data, complex systems, measurement and automation. The goal is not to manufacture spectacular conclusions, but to build tools that allow ideas to be tested against data.

PICALLW VOICE STUDIO · ANDROID

Sound you can hear, measure and visualise.

PICALLW Voice Studio combines cymatics simulation, frequency generation, recordings and acoustic voice analysis in one Android research environment. The application keeps a clear boundary between the measured audio signal, calculated acoustic features and the simulated plate response.

TECHNOLOGY & RESEARCH AREAS

Four areas, one common approach.

Different PICALLW projects share the same foundation: measurable data, transparent algorithms, practical software implementation and clearly stated limits of interpretation.

01 · COMPLEX SYSTEMS

World State Explorer

Multidimensional time series, time lags, similar historical states, anomalies and hypothesis validation.

  • ECB, geomagnetism, weather and public time series
  • correlation, Mutual Information and FDR
  • Discovery → Validation → Replication
Open Explorer →
02 · MEASUREMENT & ANALYSIS

GDV Studio Research

Research into GDV/EPI imagery together with HRV and ECG, including more transparent image analysis and longitudinal trends.

  • GDV/EPI morphology and acquisition quality
  • HRV + Polar H10 + ECG
  • personal baseline and longitudinal comparison

03 · AUTOMATION ENGINEERING

NODVIA R&D

Field diagnostics, Cloud project deployment and standalone Android HMI as one engineering workflow.

  • NODVIA Field for discovery and commissioning
  • NODVIA Studio for HMI design and Cloud deployment
  • NODVIA View as the standalone Android HMI runtime

RESEARCH PRINCIPLES

From an interesting idea to a testable result.

1MeasureCollect sufficiently reliable and correctly time-aligned data.
2DiscoverSearch for structure without forcing a predetermined conclusion.
3ValidateTest the finding on data that were not used to discover it.
4ExplainShow the method, uncertainty and plausible alternative explanations.
WORLD STATE EXPLORER

Explore the data directly.

The interactive research tool is publicly accessible. Results are exploratory statistical relationships and do not establish causation or guarantee future events.
