The initial effort is underway to introduce varied plant growth performance based on varied input levels of critical currencies, starting with carbon dioxide (CO2). Grant Hawkins of the SIMOC development team is simultaneously preparing a paper for the International Conference on Environmental Systems (ICES 2022) as he develops a deeper understanding of these known functions, as assembled through a literature review.
Today the ASU Computer Science Capstone team conducted a live demo of a sensor generating data and delivering it into the SIMOC front-end dashboard. This marks an exciting point in development as we move to provide SAM with a rich, dynamic sensor array for real-time monitoring of the breathable air, capture of the data for local observation, and display to the world via the National Geographic hosted SIMOC interface.
Notes:
– interpolated every second
– 24 seconds load and cache
– demonstrated an increase to 14,000 ppm with Greg’s breathing on the sensor
– It works! and looks great!
The SIMOC development team lead by core Python developer Ezio Melotti and Grant Hawkins, and Meridith, Greg, Ryan, David, and Ian of the Arizona State University Computer Science Capstone team have made significant strides in SIMOC development this past six months.
June-July
A major re-write of the Advanced Configuration Editor (ACE) now matches the current agent descriptions and capabilities, enabling local-install users to modify and download the configuration file, which can then be used on local installations to run custom simulations.
Other updates include:
* Jun 21, FE/INFRA: added linting check to the front-end
* Jun 23, BE/INFRA: added a basic testing framework
* Jul 1-9, BE: removed the ACE
* Jul 13, BE/SAM: added SAM agents
* Jul 26, FE: new confirmation popup
* Jul 28, FE: improved plant validation
* Jul 29, FE/INFRA: update docker image and dependencies
August-September
A User feedback survey is now included, made available from the Main menu and prompted when
exiting a simulation for the first time. This enables the SIMOC development team and sponsor National Geographic to receive feedback from users during run-time engagement.
The new 3D view now matches the user-defined habitat configuration, visible on both the Configuration and Dashboard screens.
Other updates include:
* Aug 4, FE: new modal popups
* Aug 9, FE: added the survey
* Sep 8, BE: added documentation with Sphinx
* Sep 11, FE: update to VueJS 3, bumped FE version to 1.0.0
* Sep 13, FE: added the 3D view
* Sep 22, BE/INFRA: removed DockerHub dependency
* Sep 23, BE/INFRA: removed staging branch, misc infra updates
* Sep 27, FE: improved the 3D view, fixed bugs, added rocket
* Sep 28, FE: added the simoc-web.py script
* Sep 29, BE/ABM: added a CO2 tank and makeup valve agents
October-November
The holy grail of software development, SIMOC now incorporates Pytest for unit and integration testing for the SIMOC configuration files, model and agents. Finally!
Other updates include:
* Oct 5, BE/ABM: refactored connections and added the agent_conn.json file
* Oct 10, FE/INFRA: disabled artifact creation on GitHub
* Oct 12, BE/ABM: all agents are now storages too
* Oct 18, BE/INFRA: added custom SSL certs for NGS
* Oct 20, BE/ABM: atmo storages included in cq/gh, added atmo_equalizer agent
* Oct 26, BE/INFRA: added a separate DB for testing and more BE tests
* Oct 27, BE/ABM: added the currency_desc.json file
* Oct 29, BE/INFRA: added an adminer container for DB inspection
* Nov 2, BE/ABM: created the data_files dir and moved the JSON files there
* Nov 2, BE/ABM: currency classes, sold_fertilizer replaced sold_n/p/k, more tests
* Nov 13, BE/ABM: food/ration prioritization
Early in the development of SIMOC we recognized the need to differentiate various kinds of food. While it it is the ultimate goal to track energy from fats, sugars, and proteins, we are immediately concerned with distinguishing food from rations, meaning, the food grown in-hab from the food brought from Earth. This sounds simple enough, yet it invokes a function not yet implemented in SIMOC—the ability to prioritize one currency over another in the presence of both.
SIMOC team member Grant Hawkins took on this challenge and this week complete made major strides with the effort, which invoked a moderate redesign of the means by which agents (e.g. Humans) consume their respective currencies (e.g. food, rations, water, etc.). As such, local food is the first priority for consumption, but if depleted, the humans return to consumption of rations.
Initiated in early October, the Arizona State University undergraduate Computer Science Capstone team, in concert with Ezio, Grant, and Kai of the SIMOC development team have completed a second-draft work-flow for the sensor array to be embedded in the Space Analog for the Moon and Mars (SAM) at Biosphere 2.
This design will continue to evolve as SAM is constructed and the SIMOC team dives into real-world sensor tests in place of the current SIMOC simulated data. Stay tuned!
The SIMOC development team has added the long-awaited 3D view of the habitat, available to the user both while configuring the habitat and on the SIMOC simulation dashboard. Users enjoy a dynamic visual representation of the habitat provided by space architecture designer Bryan Versteeg of SpaceHabs, such that as they select varied sizes of the habitat components, the image updates.
We are pleased to welcome David Wingar, Gregory Ross, Ian Castellanos, Meredith Greythorne, and Ryan Meneses to the SIMOC team for the next nine months. They will be working with SIMOC developers Ezio Melotti and Grant Hawkins to build a new back-end to the SIMOC web interface, providing a live data feed from the array of sensors in SAM, the hi-fidelity Mars habitat analog being constructed at the Biosphere 2.
As the SIMOC team transitions from Phase IV into Phase V development, we are shifting design and coding gears from a year spent principally in improving the scalability and stability of the SIMOC deployment across Google Cloud Platform coupled with several improvements to the user interface, back into an effort to more closely define the agent interactions, improving their real-world representation.
The first of the Phase IV updates to SIMOC is now live at the National Geographic server. This release marks a return to the evolution of the SIMOC user interface after several months work on an automated build and deployment pipeline by the development team. The current effort is focused on reducing the quantity of dashboard panels where in a single panel will have an inset pull-down menu with multiple options.
Now the Production / Consumption panel can display carbon dioxide, oxygen, water, and energy. Front-end developer Ezio Melotti states, “With the automated build and deployment system in place, we are now able to release SIMOC updates on a regular basis with the confidence of a fully tested environment. This first release lays the foundation for many more to come, soon.”
Researchers Brittany Zimmerman, MSc of the University of North Dakota and Sean Gellenbeck, PhD student of the University of Arizona are each working on advanced plant physiology experiments in which SIMOC is integrated into their research project.
Sean will be growing mushrooms and algae in a closed/sealed environment while at the HI-SEAS analog on the Big Island of Hawaii. His work will introduce a new cultivar to SIMOC. Brittany will be conducting an experiment similar to that of Kai Staats in 2019 at the Biosphere 2. Where Kai and his team monitored CO2, photosynthetic activated radiation (PAR), temperature, relative humidity, and biomass accumulation for barley fodder to give foundation to a non-linear growth function, Brittany will be growing a number of cultivars already contained in the SIMOC model to compare the simulation data to the real experiments.
Both Brittany and Sean will be directly modifying the agent description file for a local installation of SIMOC. This enables them to customize the SIMOC simulation to match the working conditions of their experiments, including volume, air flow, ambient CO2, PAR etc.
We wish them both the best of luck, and are eager to publish the results later in 2021.
