Residential Seismic Retrofit Cost For Home Located In Tustin, California, Sara Clark Jun 2020

Residential Seismic Retrofit Cost For Home Located In Tustin, California, Sara Clark

Construction Management

Seismically retrofitting a residential home not only protects the homeowner, but also helps them prepare for the future. Needless to say, many older homes are not up to the 2018 International Residential Code. As a result, many owners are uninformed about how much it will cost to retrofit their home and what changes will have to be made. The solution for this is determining a cost per square foot ratio that will help homeowners calculate an estimate for the retrofit of their home. Additionally, it is important to break this cost down into what specific changes need to be made. …

Septal Closure Device, Olivia N. Welch, Hillal H. Jarrar, Kai Harrison Jun 2020

Septal Closure Device, Olivia N. Welch, Hillal H. Jarrar, Kai Harrison

Biomedical Engineering

The septal closure device was designed to seal defects in the atrial septum. To fully seal an atrial defect, the device was designed to consist of two circular seals to cover the defect in both the right and left atria, attached with a central rod. The materials were chosen for compressibility (for ease of insertion), biocompatibility, and tissue ingrowth. A CAD model was drafted in SolidWorks. Key customer requirements include ease of implantation (specifications: adjustable sizing and clear directions for use), physician controlled (specifications: short implantation time and compatibility with current catheter/scope techniques), and a long lifetime (specifications: materials that …
