Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number.

A micromechanical model is developed to characterize the constitutive behavior of stretch broken carbon fiber (SBCF) materials. The model takes into account the characteristics of the viscous resin materials and the effect of randomly distributed discontinuous fibers. The predicted force-to-stretch (FTS) values for uniaxial stretching of SBCF prepreg tapes favorably compare with experimental data.

Edge chipping is a phenomenon commonly observed during the machining of ceramic material. Characterization of edge chipping, both in macro and in micro scale, and correlating its formation to machining parameters form a basis for developing new and innovative technologies for controlling machining induced damage. An experimental-based study using glass ceramic material is performed. Three types of edge chipping are identified. The SEM-stereophotography method and the finite element method are used to evaluate the edge chipping effect under a set of machining conditions. Significant findings are obtained and guidelines for controlling edge chipping during machining are suggested.

A pure resistor is used as a transimpedance device in this work to maximize the operating bandwidth of an on-chip integrated homodyne setup, resulting in a 240 GBits/s quantum random number generator.

A silicon photonic platform with high-speed single-photon entanglement generation and detection is demonstrated using decoy state source and homodyne detection. A CHSH Bell violation test is performed on-chip, showing a violation lower bound of 2.59.
