||CLEAR model v0.8
||CLEAR model is a system dynamics model with a graphical user-interface. This model, custom developed for the Sonoma County region tracks the C02 emissions. Two CO2 sources were modeled; transportation and electricity generation. Emissions from these sources are modeled in several sectors, including residential and commercial (industrial) transportation and electricity demand and electricity demand for water supply and treatment. Economic and population growth drive changes in demand, and policies for renewable energy (wind, solar) and low-emissions transportation (hybrid cars, mass transportation) provide mitigation choices. Climate change in the form of increases in average daily temperature drives electricity and water demand. The interface allows users to insert emission reduction energy policies, such as the photovoltaic system and wind, and transportation policies.

||Next-Generation Attribute System Control Code
||This code runs on the data acquisition (DAQ) computer and data barrier (DB) microcontroller in Next Generation Attribute Measurement System (NG-AMS). The NG-AMS is a system to measure gamma and neutron emissions from sealed containers of plutonium in order to determine attributes of the enclosed plutonium.

The IB prevents potentially sensitive information about the plutonium for being visible to the system operators, while still allowing them to verify the contents of the containers. The code on the DAQ computer is written in PERL.

||The Matlab toolbox generates daily activity schedules based on agent and "needs-based" approach. Each need (e.g., hunger, sleep) is modeled as a numeric value that decreases with a function over time and increases by doing activities that fulfill each need.
