Turnaround time reduction for military certificates of compliance - team 1

The objective of this project is to reduce the turnaround time for military Certificates of Compliance (COC) at the Milliken Company in Marietta, S.C. The first step was to determine the needs of the clients and determine the major losses of the system by performing a physical and Why-Why analysis as well as utilizing fishbone diagrams. With this information it was possible to then construct a Pareto chart to show the clients where the large percentage of losses is coming from. The team found that the key losses in the system came from having to send material to an outside lab for testing and that lab technicians allowed large losses when machines were allowed to sit idle for extended periods of time. Using this data the team will generate a set of solutions to tackle the scheduling issues that will optimize the dry-lab testing procedures

Redesign of Schneider electric rack layout into a centralized warehouse layout

This capstone design project sponsored by Schneider Electric was to create a centralized warehouse layout based on provided part usages, forklift practices, ergonomics, and warehouse procedures. Previously, storage areas were separated based on assembly lines, resulting in long times to pick parts for orders. The objective was to optimize current part placement in a centralized storage area and develop a tool to determine where to place new parts after the layout was set. Through task analyses, employee interviews, and time studies, customer needs and product specifications were determined. A root cause analysis was done to determine the main causes to be addressed in the concept generation phase. Tools including VBA, FLAP, and ergonomic standards were considered in concept generation. Moving forward, each concept will go through several iterations of testing and refining before the most beneficial solution will be chosen and implemented at the plant

TAPCHA: An Invisible CAPTCHA Scheme

TAPCHA is a universal CAPTCHA scheme designed for touch-enabled smart devices such as smartphones, tablets and smartwatches. The main difference between TAPCHA and other CAPTCHA schemes is that TAPCHA retains its security by making the CAPTCHA test ‘invisible’ for the bot. It then utilises context effects to maintain the readability of the instruction for human users which eventually guarantees the usability of the scheme. Two reference designs, namely TAPCHA SHAPE & SHADE and TAPCHA MULTI are developed to demonstrate the use of this scheme
