Sensitivity refers to the ability of a system or individual to detect or respond to subtle changes, signals, or stimuli in their environment. It is a critical parameter in fields like medicine, psychology, and engineering, where it influences diagnostics, perception, and system performance.

sensitivity

Selectivity refers to the ability of a system, process, or organism to preferentially choose or react with certain elements, compounds, or signals over others. This concept is crucial in fields like chemistry, biology, and engineering, where it impacts the efficiency, specificity, and outcome of reactions and processes.

selectivity

Response time is the total time taken for a system to react to a given input, encompassing processing, transmission, and queuing delays. It is crucial for evaluating system performance and user satisfaction, especially in real-time and interactive applications.

response time

Stability refers to the ability of a system or entity to maintain its state or return to it after a disturbance, ensuring continuity and predictability over time. It is a fundamental characteristic sought in various fields such as physics, economics, and social sciences, where it implies resilience and equilibrium.

stability

Air quality monitoring is the process of measuring the concentration of pollutants in the air to assess environmental health and ensure regulatory compliance. It involves the use of various technologies and methodologies to provide data that informs public health decisions and environmental policies.
