The Relative Thermal Index (RTI) is a measure used to assess the thermal comfort of a given environment, especially in relation to outdoor and indoor conditions. It helps in evaluating how temperature, humidity, and other factors influence human comfort under different thermal conditions. The RTI is typically used in various fields, including architectural design, urban planning, and environmental studies, to understand how building designs and landscaping can affect microclimates and overall comfort levels.

Relay logic is a control system design methodology that uses electromechanical devices called relays to control electrical circuits. This technique is commonly used in industrial automation and control systems. Key features of relay logic include: 1. **Electromechanical Relays**: Relay logic systems rely on relays, which are electrically operated switches. By energizing a relay coil, the contacts can open or close, allowing or interrupting the flow of electrical current in a circuit.

RELIKT-1 is a scientific experiment designed to study the cosmic microwave background (CMB) radiation, particularly focusing on the polarization of this ancient radiation. It is a Russian space experiment that aims to detect the signal of gravitational waves from the early universe, which would provide insights into cosmic inflation—a rapid expansion that is theorized to have occurred just after the Big Bang. Launched in 2016, RELIKT-1 operates as a space-based observatory equipped with sensitive radio receivers.
