This small but powerful application was developed with relatively new technologies at that time (Spring Data, Spring MVC, Spring Boot) in less than two months, by a team of only 3 active developers.

We had the pleasure of learning new technologies in a very agile process (getting quick feedback from the product owner, tester and front-end designer) but always with an eye on the calendar, as our deadline was fixed and very tight from the beginning.

The EBRAINS 2.0 project aims to establish a new standard for brain atlases, connect foundational multilevel data, and push forward digital twin approaches through modelling and simulation.

• Establish simulation tools for multiscale brain models across species, systems and behaviours.
• Provide digital brain twins with modular, configurable, ready-to-use brain model templates for the whole brain and its subsystems, integrated with other EBRAINS tools and services to support a wide range of scientific use cases.
• Enable and facilitate the use of multiscale brain models by providing integrated tools for analysis, visualisation, validation and inference of digital brain twins.
• Maximise usability of multiscale brain models and digital brain twins.
• Define clear procedures, technical requirements and interfaces to enable the larger community to contribute modelling and simulation tools to EBRAINS in the future.

Hygie is a browser-based platform for brain exploration that generates patient-specific digital twins from standard structural and functional neuroimaging.

• It provides automated preprocessing, personalized whole-brain simulations that reproduce EEG, MEG, and BOLD dynamics, advanced inference modules, and an interactive 3-D viewer.
• Clinicians and researchers can conduct diagnostics, prototype virtual surgeries or stimulation protocols, and juxtapose simulated signals with each individual’s empirical data.
• Offered for research, education, and investigational clinical studies, Hygie streamlines collaboration and accelerates hypothesis testing in neuroscience and precision medicine.
• Built to fit into clinical and research environments, Hygie supports standardized data import from multimodal sources and ensures interoperability with existing neuroimaging and electrophysiology systems.

IT Cube is a custom monitoring system providing real-time status of the entire PBeaKK infrastructure, server and application landscape.

State data is collected using different techniques/channels like WMI, HTTP, ODBC calls, logfiles and CSV.

Visualization is organized in a multi-dimensional "cube" and tailored to different user groups responsible for different systems. It also provides ways to react in advance and avoid IT outages.

The application contains modules implemented in .NET for collecting data while the aggregation and visualization UI uses Java.
