A Graph Based Departmental Spoken Dialogue System, Julia Isaac
A Graph Based Departmental Spoken Dialogue System, Julia Isaac
Honors Theses
Spoken dialogue systems are automatic, computer based systems that are a great way for people to receive important information. In this project, I created a spoken dialogue system that people can use to learn about the Computer Science Department at Union College. The system was built by populating an open source dialogue system using a graph based dialogue manager. I improved upon a previous working dialogue system by making the conversations sound more natural, improving the flexibility of the system and making the system more robust. To help with this process a corpus was created using about 200 different dialogues …
Atomic Force Microscopy Of Poly(Ethylane-Oxide) Crystalization, Xavier Capaldi
Atomic Force Microscopy Of Poly(Ethylane-Oxide) Crystalization, Xavier Capaldi
Honors Theses
Polymer crystallization is a complex process which is influenced by a variety of factors. Atomic force microscopy is used to explore the material properties of polymer crystals. Poly(ethylene-oxide) is used in a variety of molecular weights as the sample. In addition, a variety of sample preparation methods and microscopy modes were tested. A relatively new imaging technique was identified for the characterization of polymer crystals: amplitude modulation-frequency modulation viscoelastic mapping. This mode was used to measure material properties such as stiffness and dissipation.
Gasoline Confined In Nano-Porous Media, Matthew Giso
Gasoline Confined In Nano-Porous Media, Matthew Giso
Honors Theses
The heat of combustion was determined for gasoline confined in nano-porous media of differing pore size by bomb calorimetry. The heat of combustion of the confined fuels was comparable to that of bulk within the experimental uncertainty. This suggests that all of the confined fuel burns without any flame quenching and no chemical interactions at the interface between pore walls and fuel mitigate combustion.
Heat Of Fusion Of Primary Alcohol Confined In Nanopores, Harrisonn Griffin
Heat Of Fusion Of Primary Alcohol Confined In Nanopores, Harrisonn Griffin
Honors Theses
Melting behavior of physically confined 1-decanol in nano porous silica was probed using a Differential Scanning Calorimeter (DSC). In agreement with the Gibbs-Thomson prediction, we observe that the melting temperature of the confined 1-decanol scales inversely with the physical size of the pores. Contrary to the assumption used in developing the Gibbs-Thomson equation, however, the apparent heat of fusion decreases as the pore size decreases. Previously, several models have been proposed where interfacial layers of molecules do not participate in the phase transition and thereby would not contribute to the heat of fusion. While these could reconcile the seeming contradiction, …
