Compliant Meso-Scale Grinding of Silicon
To further improve form accuracy obtained on the compliant grinding apparatus, a normal grinding force model and a depth of cut model were developed to account for the large compliance in the grinding system. Numerical simulation was performed to predict actual depths of cut and the results were …

Flow Boiling in Meso-Scale Pin-Fin Coldplates
… flow boiling in pin-fin-enhanced channels in the meso-scale, has limited the availability of physical insights, data, flow regime maps, and correlations that assist in the design of two-phase coldplates. Dielectric fluid flow boiling in a millimeter-scale coldplate was experimentally investigated …

Synthesis and functionalization of novel meso-substituted tetrabenzotriazaporphyrins
… are the focus of this thesis. They have a single meso-carbon linkage which can offer an additional site for the attachment of various functional groups, thus would provide a wide range of functionalized TBTAP derivatives. The syntheses of the phthalonitriles have been achieved successfully through …

Meso : a virtual musculature for humanoid motor control
Humanoid behavior requires a system with access to humanoid variables. Our humanoid robot, Cog, has two arms that are structurally similar to those of humans; however, the sensory system only provides a sense of strain and position. This thesis describes a model of the human energy metabolism that …

Thermomechanical Meso-Scale Modeling of Combustion of Heterogeneous Solid Propellants
In the final part of this dissertation, the coupled thermomechanical and propellant surface regression solver is further enhanced through addition of fluid-phase equations for transport of chemical species and temperature. A simple three-step kinetics model is used to describe the complex reactions …
