Domain | to reduce entropy | to protect channel | to retain integrity | to drive flow |
Fluid | reduce charge loss | sustain channel volume | set and restore tightness | create pressure difference |
Electric | reduce heat losses | prevent short circuits | prevent leakage currents | create electric potential difference |
Mechanical | reduce mechanical losses | prevent corrosion | reduce flexibility | house bearing |
Thermal | reduce heat resistance | reduce fouling | reduce heat losses to environment | create temperature difference |
Information | reduce spent energy per bit | reduce noise | reduce data loss | supply power |
Function | limit cost | define robustness | define availability | define performance |
Method | ease communication | prevent noise | retain information | define deadline |
Software | require predictability | require robustness | require stability | define time response |
Vegetables | reduce charge losses | prevent attacks | retain fluids | Drive water and nutrients |
Animal body | reduce energy for displacement | protect against aggression | keep fluids, nutrient, and heat | drive movement |
Animal mind | seek cooperation | maximize minimum payoff | retain status | maximize maximum payoff |
Enterprises | seek freedom | manage risks | seek stability | make profit |
