Sensors and Actuators: Differences, DAQ, Types & Applications
Q1: Sensors vs Actuators — Detailed Explanation
Definition of Sensor
A sensor is a device that detects, measures, or senses a physical quantity such as temperature, pressure, displacement, light, humidity, flow, etc., and converts it into a usable electrical signal (voltage, current, resistance).
Sensors act as the input element of any measurement or control system.
They form the first stage of data acquisition.
Without sensors, a system cannot perceive real-world conditions.

Effective Classroom Tools: Logs and Journals
Logs and journals are essential tools in the classroom. A journal is a notebook in which students record their personal reflections, questions they are wondering about, ideas, words or expressions they want to remember, or feelings they have about experiences in class. Logs are usually more objective; for example, they include observations on learning activities, lists of books read or films watched, notes on learning strategies, and so on.

EM Algorithm, K-Means, and Ensemble Methods Explained
1. Expectation-Maximization (EM) for GMMs
The Expectation-Maximization (EM) algorithm is an iterative method used to estimate parameters in statistical models that involve latent (hidden) variables, such as missing data or unobserved groupings. It is especially useful for fitting models like Gaussian Mixture Models (GMMs), where the data is assumed to come from a mixture of several Gaussian distributions, but the assignment of each data point to a specific Gaussian is unknown.

Assumptions of Deterrence Theory
Severity, Certainty, and Swiftness (Celerity) lead to greater control over criminal behavior.
Three Principles of Deterrence Theory
- Severity: Degree of punishment.
- Certainty: Assurance and consistency of punishment.
- Celerity (Swiftness): Speed of punishment.
Alternative Explanations for Assessing Deterrent Effects
- Backlash: Committing more crime.
- Crime Displacement: Shifts in the time, place,
