- Internet of Things: platform that the smart city depends on, how sensors communicate with people
- Be able to list at least one disadvantage of having publicly accessible data
- Privacy
- Abuse of data
- Hackers
- Control by technology companies
- What is a smart grid? (efficient distribution and usage of electricity)
- Give an example of a technology you might find in a smart city (traffic lights, street lights, trash cans, tourist apps, traffic and snowplow apps to monitor real time conditions, filing reports with government, bike sharing)
Temporary Housing
- Be able to list 3 design considerations:
- Domestic economy (local suppliers)
- Rapid availability
- Ease of assembly/deployment
- Affordability
- Community participation
- Compatibility with local living
- Appropriate for duration of living (could it evolve into permanent structure if quality of living is high enough?)
- Easy and non polluting disposal
- Physical characteristics (surface area, topography, altitude, ambient temperature degree, wind speed, relative humidity, etc.)
- Economic propsect of the temporary settlement
- Be able to give one example of a temporary housing design
- Concrete tent
- Superadobe structures
- Pallet houses
- Exo (stackable box)
- Hexayurt
Population Growth Models
- Exponential
- No resource limitation, ideal situation
- dN/dt = r*N where r = birth rate - death rate
- Logistic
- Carrying Capacity K = maximum sustainable population
- dN/dt = r*N(K-N)/K
- Ecosystem diversity increases stability. Empirical evidence:
- Tilman Grassland Experiments.
- Decade long experiment. different number of types per plot
- More types of plants increased the stability of the plot
- Real world food webs are stable because interactions between species are weak
- Why are food chains so short?
- Most 3-4 trophic levels
- Energetic limitations (10% trophic transfer efficiency)
Seismology
2 methods of anti-seismic construction
1. tuned mass damper
2. base isolation
