Safe Cats vs Structural Dynamics Visualizer

Safe Cats is the official safety app of Montana State University. It is the only app that integrates with MSU's safety and security systems. The MSU Police has worked to develop a unique app that provides students, faculty and staff with added safety on the Montana State University campus. The app will send you important safety alerts and provide instant access to campus safety resources. Safe Cats features include: - Emergency Contacts: Contact the correct services for the MSU area in case of an emergency or a non-emergency concern - Friend Walk: Send your location to a friend through email or SMS on your device. Once the friend accepts the Friend Walk request, the user picks their destination and their friend tracks their location in real time; they can keep an eye on them to make sure they make it safely to their destination. - Tip Reporting: Multiple ways to report a safety/security concern directly to MSU security. - Safety Toolbox: Enhance your safety with the set of tools provided in one convenient app. - Notification History: Find previous Push Notifications for this app with the date and time. - Share Map with your Location: Send your location to a friend by sending them a map of your position. - I’m OK!: Send your location and a message indicating that “You’re OK” to a recipient of your choosing. - Campus Maps: Navigate around the MSU area. - Emergency Plans: Campus emergency documentation that can prepare you for disasters or emergencies. This can be accessed even when users aren’t connected to Wi-Fi or cellular data. - Support Resources: Access support resources in one convenient app to enjoy a successful experience at MSU. - Safety Notifications: Receive instant notifications and instructions from MSU safety when on-campus emergencies occur.

Structural Dynamics Visualizer is an interactive educational tool for exploring the behavior of vibrating structural systems. Visualize free vibration, forced vibration, mode shapes, sinusoidal ground motion, and earthquake response using animated structural models and synchronized response plots. Explore single-degree-of-freedom and multi-degree-of-freedom systems, including carts, shear frames, cantilevers, and vertical spring-mass systems. Adjust model parameters such as mass, stiffness, damping, initial displacement, initial velocity, forcing amplitude, forcing period, and number of degrees of freedom, and immediately see how those changes affect structural response. Features include: • Free-vibration response and damping behavior • Forced vibration and resonance visualization • SDOF and MDOF structural models • Mode shapes and modal response • Shear-frame and cantilever systems • Sinusoidal base excitation • Earthquake response using recorded ground motion • Interactive parameter controls • Animated structural deformation • Response histories and natural-period visualization Structural Dynamics is designed as a teaching and learning aid for students studying structural engineering, earthquake engineering, vibrations, engineering mechanics, and related subjects.
