Have you ever wanted to see how a beam or bridge you encounter in everyday life reacts when load is applied? What if you could see these in your space at all angles, without having to specify material types, meshing or boundary conditions? STRUCT-AR utilizes finite element models pre-loaded into this mobile AR application that allows users to interact and engage with the models on their mobile device or tablet. This can be used as a complementary teaching tool for enhancing personalized learning wherein students can leverage the technology as a learning companion both within the classroom and outside to better understand structural behaviors and mechanisms that are challenging to convey in a traditional 2D learning environment. To use the app, you must allow it to access your camera. No identifiable data is stored on any server and you can revoke access at any time.

TerraOorja: Explore the Future of Energy Ever wonder how policy changes, new technologies, and behavioral shifts really impact our energy future? TerraOorja puts a powerful energy transition model in your pocket. Simulate complex scenarios and discover the most effective pathways to decarbonization. Unlike simple calculators, TerraOorja uses Agent-Based Modeling (ABM) to simulate households and businesses making independent decisions year after year. Watch how energy use and carbon emissions evolve in response to the parameters you control. Key Features Simulate Dynamic Scenarios: Adjust dozens of parameters across Basic, Advanced, and Expert modes—subsidies, grid decarbonization rates, efficiency standards, climate impacts, and more. Advanced ABM Simulation: Hundreds of autonomous agents represent households and businesses with unique finances, equipment, and decision-making styles. In-Depth Analysis: Explore year-by-year results for energy consumption by source, Scope 1 & 2 CO₂ emissions, and total CAPEX. Interactive Dashboards: Visualize results with clear charts and reorderable dashboards to focus on the metrics that matter most to you. Realistic Decision Models: Choose Behavioral (peer influence, anxiety), Rational (NPV, IRR), or Mixed Mode for realistic populations. Privacy First: All simulations run entirely on your device. No data is collected or shared. How It Works TerraOorja builds a virtual society of households and businesses. Each year, agents decide whether to upgrade equipment like HVAC systems, appliances, and water heaters—based on age, finances, subsidies, and behavioral profiles. Their individual choices combine into a system-wide view of energy use and emissions over time. What You Can Model Impact of subsidies (e.g., 50% for heat pumps). Effects of grid decarbonization (e.g., 7% annually). Climate-driven demand changes (e.g., +2.5°C rise). Equipment lifetimes vs. efficiency improvements. Who It’s For Policymakers & Urban Planners testing initiatives. Students & Educators learning sustainability and energy systems. Analysts & Consultants modeling green investments. Business Owners exploring decarbonization strategies. Curious Citizens passionate about climate solutions. Disclaimer TerraOorja is for educational and informational purposes only. Default parameters reflect typical California households but can be adjusted for other regions or businesses. Results should not be considered financial, investment, or engineering advice. Please consult a qualified professional before making financial decisions.
