Fall 2011 Contributions

I worked on two different design challenges in the Fall 2011 semester. The first was to design and write the code for a floc skimmer, which is a length of PVC pipe in each bay of the sedimentation tank that is used to remove any floating flocs that escaped the floc blanket and reached the surface of the water. The second task was to find and implement an automated method to allow anyone who requests a plant design to assign materials in the AutoCAD drawing, which would make it easier for someone to visualize the proposed design as it would look in the real world. The final presentation of both of these challenges can be found here, along with pictures.

Spring 2013 Contributions

In the Spring 2013 semester, I continued the work of Kira Gidron from the Fall 2012 semester on the Materials List. I completed code designed to separate a PipeMatrix (which will come from changes in code to all pipe-drawing functions) into smaller matrices, each of which contains only rows with the same ND and EN values. PipeMatrix will consist of rows that each represent different pipes used to construct a requested plant design; each row contains a pipe's length, nominal diameter (ND), pipe schedule/specification (EN) and number of times it is arrayed. I also started code that will use these smaller matrices to find out the minimum number of lances (6.1 meter lengths of pipes sold in Honduras) needed to construct any given plant design. This section of code has not yet been completed.

Spring 2014 Contributions

This semester, I expect to be continuing my work on the Materials List design challenge that I worked on during the Spring 2013 semester.
