Show moreAnalytical experiments and computer simulations have shown unusual thermal conductivity behavior of soft material under mechanical strain. At first, the conductivity decreases with the increase of the mechanical strain. After reaching a certain minima, with the application of additional strain, it starts increasing. While this behavior is confirmed via experiments as well as computer simulations using molecular modeling techniques, what causes this behavior is still considered an open question. This thesis studies the molecular simulations data from multiple simulations and investigates the use of machine learning techniques to understand the unusual thermal conductivity behavior of soft materials under mechanical strain. The data sets consists of terabytes of data with thousands of spatial as well temporal attributes. In particular, the influence of attributes related to molecular structure including bond length, bond angle, and dihedrals has been probed. Several machine learning and data mining techniques including clustering and association rule mining have been applied on different datasets with different thermal conductivity to find the relationship between the soft material molecular structure and thermal conductivity behavior. The results show that in the alkyls molecules the most important features that affect the thermal conductivity are the O-CH2 bond properties, especially when thermal conductivity is equal to 1.5±ε . Keywords: Thermal conductivity, bond angle, bond length, dihedral angle, association rule mining, ANOVA significance test, K-means clustering.

Show moreOver the years, pulsed terahertz (THz) time domain spectroscopy has attracted a lot of interest since it can not only measure the intensity of the transient electric eld but also determine the amplitude and phase of the spectral components that make up the pulse. This provides a convenient method to obtain the molecular network information of chemical or biological samples. Signi cant e orts have been directed towards free space spectroscopy in which THz pulses travel in free space between photoconductive transceivers. Due to di raction limit, the resolution is insu cient for many applications and it results in extreme power requirements or low power densities of the probe pulse. To overcome this issue, we propose a planar THz spectrometer which uses the same photoconductive excitation and detection mechanism as free space spectroscopy, but the excited THz pulses are directly coupled into lithographically de ned coplanar transmission lines. To reduce the power loss in the substrate, a thin lm with lower permittivity is employed to replace the conventional silicon substrate at the location where the coplanar waveguide is fabricated. To obtain high sensitivity, sample can be directly placed on the coplanar waveguide for tight coupling of the eld. Conceptual design and EM simulations have been completed and a variety of experimental studies have been carried out at Argonne National Laboratory to understand the fundamentals of coplanar waveguide. The fabrication of the coplanar waveguide prototype have been conducted at Northern Illinois University. The challenge of building a photoconductive switch with LTG-GaAs on Si3N4 was encountered and an innovative wafer bonding technique was discovered. Several wafer treatments prior to and after wafer bonding have been demonstrated to improve the bonding strength and reduce the defects. A standard pump-probe optics setup has been built at DePaul University and the photoconductive switch have been tested with femtosecond laser. The results con rmed that the photoconductive switches are functioning as design and the device system is ready for THz spectroscopy application. The historical overview of THz spectroscopy research and fundamentals of coplanar waveguide and photoconductive switches are presented in Chapter 1-3, followed by EM simulation, conceptual design in Chapter 4. The details of microfabrication process and the testing results are discussed in Chapter 5 and 6. The project is summarized in Chapter 7.

Show moreDetecting humans in images or video sequences is a challenging task owing to their variable appearance and the wide range of poses that they can adopt. The first and most important factor in achieving satisfactory detection result is robust feature set that allows the human form to be discriminated clearly, even in cluttered background under difficult illumination. Many researchers endeavored to find a robust and light descriptor for human body for over twenty years. Some of them have presented enlightening approaches and promising performance, such as histogram of oriented gradients [1], purposed in 2006 and speeded fast robust feature [2] purposed in 2008 are both outstanding holistic features that give a nice description of pedestrian. Recently a rising trend in part-based approaches pedestrian classification aims to deal with occlusion occasions happen frequently in real world urban street scenarios. By dividing the pedestrian’s body image into several parts relaxes the detector’s emphasis on the whole pedestrian body. Even when part of pedestrian’s body cannot be seen in the image, the rest part of the body will still contribute to the classification.
