Understanding Natural Disaster Risks
Risk Assessment: Risk level depends on several factors:
- Hazard (Peligrosidad): Probability of an event occurring.
- Exposure (Area Afectada): The value and number of people or assets in the affected area (ecological, economic, and cultural zones).
- Vulnerability: Percentage of susceptibility to damage and potential for victimization.
The risk can be calculated as: RISK = Hazard * Exposure * Vulnerability

Fricatives and Affricates: Parameters
Parameters
- Voice: voiceless, voiced
- POA: Dental, Alveolar, Post-alveolar, Glottal
- MOA:
- Degree of construction: fricative (vs. approximants vs. ‘stops’)
- Speed of release of the closure: affricate (vs. plosives)
- Laterality: median (vs. lateral) fricatives/affricates
- Tongue shape: grooved fricative/affricate vs. slit fricative/affricate
Fricatives are produced by forcing air through a narrow channel. This channel is made between the active and passive articulators drawn

Cryptography Fundamentals
1. General Model for Communication
- Alice wants to send a message m to Bob.
- Eve is an adversary who may try to eavesdrop or modify the message.
- The goal of cryptography is to ensure that Eve cannot read or alter the message without authorization.
2. Encryption: Preventing Eavesdropping
- Encryption is used to prevent Eve from reading the message.
Key Concepts:
- Secret Key (Ke): A shared key between Alice and Bob. The longer the key, the higher the security.
- Plaintext (m): The original
