Key Points – Supports recovery from major outages – Uses cloud-hosted backup or standby resources – Common in continuity planning – Can reduce recovery time and infrastructure duplication – Often includes standby systems, replicated data, and tested failover procedures –…
Key Points – Monitors software liveness – Triggers recovery on timeout – Used in embedded and critical control systems – Detects stalled, hung, or unresponsive behavior – Expects periodic service or heartbeat events from software Definition Watchdog Timer is a…
Key Points – Uses feedback to regulate behavior – Found in industrial and automation systems – Supports stability and setpoint tracking – Can be open or closed depending on design – Continuously or periodically senses process state, calculates error relative…
Key Points – Orders actions into a prescribed sequence – Used for startup, operation, and shutdown routines – Common in automation and process control – Ensures processes follow correct progression during all operational phases – Works by advancing through predefined…
Key Points – Provides broad coverage rather than narrow focus – Useful for acquisition or omnidirectional needs – Common on mobile, remote, and backup links – Distributes energy across a larger angular area rather than concentrating into a narrow beam…
Key Points – Provides oversight above local control loops – Coordinates setpoints, alarms, and modes – Common in SCADA-style environments – Observes process state and issues commands to local controllers – Handles alarms and coordinates distributed control points – Typical…
Key Points – Checks prerequisites before enabling action – Common in start permissives and safe sequences – Supports safe operation in industrial systems – Used in process control, machinery control, and safety-related systems – Often complements interlocks and shutdown functions…
Key Points – Dissipates heat through radiation – Common in spacecraft thermal design – Works with internal heat sources and thermal paths – Sized and placed to balance thermal rejection with environmental exposure – Passive thermal control mechanism without active…
Key Points – Represents process behavior over time – Used for testing, design, and training – Supports control and operational analysis Definition Process Simulation Model is a model that represents process behavior so engineers can test, analyze, or predict how…
Key Points – Directional transmission toward the network or satellite – Opposite of downlink in satellite and mobile systems – Used in satellite communications, mobile networks, and wireless systems – Important for link budget and interference analysis – Performance varies…
