Problem Set 5: Particulate Transport

In this problem set you will be simulating particulate emissions from a single vehicle moving along a straight road with a cross wind. You will develop a particle tracking model to visualize the particulate plume and to compute atmospheric concentrations.

Problem Set 4: MATLAB Practice

This problem set is designed to give you some practice with MATLAB programming. You should develop your own programs rather than modify those handed out in class. The programming problems given here are based on simplified versions of the Exam 1 problems.

Problem Set 3: Thermal Analysis for a Small House

In this problem set you will be evaluating the energy performance of a house using a MATLAB model you construct. Your model will include heat gains and losses from heat conduction, convection, and radiation as well as heat gains from a thermostatically controlled furnace. You will be examining the effect of changing windows, and other structural components.

Problem Set 2: Species Competition

This problem builds on the class lectures about predator-prey ecosytems. Rather than predation, we consider two similar species competing for a common resource. We use the Lotka-Volterra competition model, which embodies the “competitive exclusion” principle:

"If two competing species coexist in the same niche in a stable environment then one species will eventually crowd out the other.”

Assignment 9

Please read Chapters 1 and 2 of our textbook, Joseph Murdoch's Illuminating Engineering. How to do this

Please take on the following tasks:

  1. Illuminance measurements. Use an illuminance meter to record light levels in residential spaces, including those used for food preparation, reading, and such detailed manual labor as sewing or electronics repair (i.e., a home shop or work room).
  2. Review IES illuminance criteria (from Murdoch or, better, the IES Handbooks which are in the lab and in the Rotch reference collection) for activities you think appropriate for a Gujarati house.
  3. Define desired lighting levels and any issues about light quality for a Gujarati house, on the basis of Tasks 1 and 2.
  4. Use the illuminance meter to estimate reflectances for typical walls and floors, including those in your test rooms.
  5. Review IES data on surface reflectances.
  6. Define desired wall, floor and ceiling reflectances for upcoming daylighting models of Gujarati houses.
  7. Select a Gujarati house, select modeling materials, and construct a model. Please pay attention to:
  8. Accurate dimensions, with careful notes about choices when available information is inadequate.
