The goal of this program is to design a lightweight optical bench capable of remaining stable under temperature and moisture changes, while isolating the precision optical array from vibrations such as engine noise and air turbulence. By integrating a customizable periodic stack in the bench, vibrations are attenuated more effectively than commercially available mounts. Additionally, the periodic ...

Surgical simulations aiming to support surgeon practices and medical education have attracted enormous research effort over the last two decades. However, the physical reality, especially on simulating aggregated tissue interaction, is still unsatisfactory. In this proposed work, an open source surgery simulation framework, SoFMIS, will be utilized and enhanced with tissue interaction models to a ...

Realistic surgical simulation requires a combination of representative tissue geometry, accurate tissue material properties and lifelike tool-tissue interaction forces. Recent advances in computational power and imaging modalities have provided the capability to represent the anatomical details required for surgical training; however, the mathematical models which govern the underlying tissue pro ...

BioMojo LLC and the Departments of Mathematics and Biomedical Engineering at the University of North Carolina Chapel Hill, will develop a preliminary bio mathematical model framework to represent how human tissues interact and behave at their boundaries. Tissue interaction properties (e.g. tensile, shear, friction, and so forth) of connective, epithelial, muscular, and nervous tissue including su ...

Thermally induced fatigue and residual stress introduced during fabrication are sources of failure in microelectronics, which raises reliability concerns for MDA and its system integrators. CFDRC has teamed with experts in the reliability of microelectronics packaging to develop a physics based modeling and testing protocol to correlate material properties and thermal loading conditions to stress ...

The objective of the proposed work is to develop, demonstrate, and evaluate new technologies for low-cost, high-accuracy, whole-building CO2 monitoring for demand control ventilation. The work builds on a private/public partnership formed between Dioxide MaterialsTM and the Institute for Sensing and Embedded Network Systems Engineering (I-SENSE) at Florida Atlantic University. In previous, NSF-sup ...

Replacement of petroleum based vehicles with fuel cell electric vehicles operating on hydrogen produced from domestically available resources would dramatically decrease emissions of greenhouse gases and other pollutants as well as reduce dependence on oil from politically volatile regions of the world. One major inhibitor to a hydrogen society is the lack of infrastructure, which requires hydroge ...

Many communities face water scarcity as a fundamental challenge to their economic and social development. Seawater is an abundant source which can be reached by most of the countries in the world. In order to utilize seawater as potable water, it is required to remove the high salinity. Desalination technologies are intended for the removal of dissolved salts that cannot be removed by conventional ...

High selectivity in chemical reactions is the key to reducing costs, energy consumption and emissions in chemical processing. More selective and active catalysts will reduce the need for recovering unreacted chemicals for recycle and removing byproducts. Reducing the burden on separation processes will greatly reduce the energy required for chemical production. We propose to design macromolecular ...

Maximizing the value proposition for solar and distributed energy resources to consumers requires a more integrated and coordinated approach to utilizing these resources on-site. Commercial solutions are not yet widely available to provide optimal use of combined on-site resources locally, while at the same time optimizing their value to the electric power distribution system as well. Solutions st ...
