Keywords

💡Telecommunications infrastructure

Telecommunications infrastructure refers to the physical and organizational structures required to establish and maintain communication services between various devices and networks. In the video, the importance of this infrastructure is highlighted in the context of natural disasters, emphasizing the need for reliable and secure systems to maintain societal connectivity and function.

💡Electrical infrastructure

Electrical infrastructure encompasses the power plants, transmission lines, and distribution systems that deliver electricity from suppliers to consumers. The video discusses how this infrastructure can be affected by natural disasters and the importance of designing resilient systems to ensure continuous energy supply.

💡Natural disasters

Natural disasters are catastrophic events caused by natural processes of the Earth, such as earthquakes, floods, hurricanes, and tornadoes. The script mentions that Chile is particularly prone to such events, which underscores the urgency of researching and developing infrastructure that can withstand these phenomena.

💡Stochastic models

Stochastic models are mathematical models that incorporate randomness to represent uncertainty and variability in systems. In the context of the video, these models are used to predict and evaluate the fragility of infrastructure components and to inform decisions on where to invest in infrastructure improvements to enhance resilience.

💡Reliability

Reliability in the video refers to the ability of telecommunications and electrical infrastructure to perform its required functions under stated conditions for a specified period of time. The discussion emphasizes the need to build infrastructure that is not only reliable under normal conditions but also during and after natural disasters.

💡Resilience

Resilience is the capacity of a system to recover quickly from difficulties, in this case, natural disasters. The video explores how infrastructure can be designed to be resilient, meaning it can absorb shocks, recover, and adapt to maintain functionality.

💡Interdependence

Interdependence in this context refers to the way different parts of a system rely on each other. The video discusses how the failure of one part of the infrastructure, such as roads, can impact the repair of another, such as electrical lines, highlighting the interconnected nature of infrastructure systems.
