This is a group report made by a group of 5 including myself during the Spring 2018 semester, at Houston Community College. We designed a modular ratchet system, and looked at how feasible it would be to produce them based on cost of materials and labor. Modular Ratchet System General πnamics (GRUP3)         INSTRUCTOR: Prof. Abdul Qureshi COURSE: ENGR-1204 CLASS NO: 52764   TEAM MEMBERS: Damian Kao Paulo Cisneros Roy Welsh  Steven Smith Yan Ng Problem Statement  Creating a Modular Ratchet System that is cost effective, and versatile, capable of handling the tasks done by two separate tools. Introduction General πnamics (GRUP3) is proud to introduce the Modular Ratchet System. The Modular Ratchet System (MRS) is a standard 1/2” ratchet with a handle that will securely attach an extension for use when high torque is needed. The MRS eliminates the need for a seperate ratchet and breaker bar, considerably reducing expense for the end user. Group Member Ro...

This was my Fall 2019 Project paper on Polymer based electrolytes used in Solid State Batteries. It was a topic I chose to study after completing my Summer 2019 Internship with Dr. Haleh Ardebili on creating computer based simulations related to thermal properties within Li-ion cells.

This was a group report meant to study the workings of the original Biosphere project from the 1990s, and try to come up with solutions to its faults, while also suggesting methods for potential martian habitats. Biosphere 2.1 MECE 4343 Thermal Design Group 7 Date: 04/30/2020 Written By : Anh Phung, Damian Kao, Aldor Shkurti, Andrew Ibarra, Cristian Castellanos Abstract The failed Biosphere 2 project ended 26 years ago. This project has been the only real attempt to create an artificial, materially closed ecological system, and ended in complete failure. This study will analyze all the problems related with technical results of Biosphere 2 closure such as oxygen levels and CO2 concentrations. After the first crew entered Biosphere 2, oxygen levels started to fall and were not close to normal levels. Oxygen levels reached as low as 14.5% after 16 months dropping from an initial of  20.9%. As for CO2  concentration, levels rose as high as 4000ppm from 1000ppm during the two year...
