Visual Regression is a general task in the area of computer vision, with input visual data space and continuous output space. Most learning-based visual estimation tasks, where the output variables take values in continuous space, are related to visual regression. Examples of visual regression include many emerging but very difficult...
We tackle two important theoretical problems in macroeconomics and international economics. First, in macroeconomics, especially monetary economics, the models with a standard Taylor rule have multiple equilibria. This multiplicity is problematic since we do not have a theory to determine a price level. We propose a theory to pin down...
Machine learning and symbolic reasoning have been two main approaches to build intelligent systems. Symbolic reasoning has been used in many applications by making use of expressive symbolic representations to encode prior knowledge, conduct complex reasoning and provide explanations. Recently, machine learning has enabled various successful applications by learning from...
Stringent demands in the sheet forming industry related to rapid and customized part realization coupled with rigorous requirements on geometric accuracy and product properties have outpaced the capabilities of traditional forming processes. As an emerging novel technology, Double-Sided Incremental Forming (DSIF) offers much higher flexibility with the complete elimination of...
Many phenomena that occur in the nanoscale, such as the self-assembly of charged amphiphiles, the metal extraction for recovering rare earth elements and nuclear waste as well as water purification, are driven by the electrostatic forces. Although current simulation techniques can handle the long-range Coulomb potential efficiently, the inhomogeneity in...
The dissertation consists of three separate essays that lie at the interface of social network analytics and Customer Relationship Management (CRM). Essay 1 and Essay 2 cover completed research, while the research covered in Essay 3 is at a more preliminary stage.', 'Essay 1: Starting Cold: The Power of Social...
Biology is entering the exciting world of big data. Modern high-throughput experimental techniques often produce large datasets that aim to capture complex relationships often found in biological systems. While these larger data sets contain vast amounts of useful information, the answers are often locked behind a wall of numbers. As...
In the last decade, global mobile data traffic increased by more than a hundred fold times while maintaining essentially the same monthly charge to the average mobile user. Cisco predicts that overall mobile data traffic will continue to grow rapidly at a compound annual growth rate of 60 percent between...
In college, high levels of student engagement, including the formation of relationships with faculty and staff, are positively associated with learning and development. Faculty and staff, known as institutional agents, can provide critical forms of institutional knowledge, resources, and services that can enhance the college experience and encourage student success....
My dissertation is an autoethnography, tracking my experience creating the Great Chicago Fire Festival for and with the City of Chicago. The production was a nearly unprecedented collaboration between an arts organization and a major municipality. It involved 7 different city agencies and 3 federal departments; more than 6000 city...
Intermolecular charge transfer between electron-rich donor and electron-poor acceptor molecules offer great promise in the development of novel, low-cost electronic materials. It is hypothesized that control over the intermolecular interactions and supramolecular self-assembly of these systems could tune electronic properties and discover new functions. To that end, a series of...
Demands in the aerospace, automotive and biomedical sectors for low-volume sheet metal parts made from materials with high specific strength are growing due to the needs imposed by rapid product development cycles, and personalized products to mention a few. However, high strength-to-weight ratio materials, such as Ti6Al4V, are usually difficult...
Composites of metal nanoparticles encapsulated by metal-organic frameworks (NP@MOFs) have recently emerged as intriguing heterogeneous catalysts for regioselective reactions. Sharing qualities of both zeolites and enzymes, these catalysts employ the pore system of a MOF to direct reactant access to the surface of nanoparticles. This dissertation seeks to better understand...
The recent development of quantum biology results in various breakthroughs in exploring the role of quantum physics in biological systems, as well as in observing and controlling light-matter interactions in biological materials on a fundamental quantum level. We seek to combine the concept of quantum biology with quantum optics to...
Recent years have witnessed success in using mathematical models to understand complex social phenomena. In this dissertation, we develop and apply two mathematical models in the area of urban productivity and political elections. ', 'First, we investigate the puzzling superlinear scaling behavior of many outputs in urban areas, such as...
Precise assessment of long-term aging and deterioration play a major role in life-time predictions of concrete structures. One of the primary challenges in studies of cementitious materials such as concrete comes from the fact that multiple chemical reactions are happening in parallel. Environmental conditions present another challenge as they can...
The phase-field crystal (PFC) model is an exciting new method for simulating crystalline materials with atomic resolution over diffusional time scales. Unfortunately, applications of the model have been severely limited by the requirement that novel free energies must be constructed for each new material of interest. This thesis describes three...
Meiosis is a specialized form of cell division where chromosomes are duplicated once and segregated twice, in order to reduce the chromosome number by half to generate haploid gametes. In contrast to mitosis, oocyte meiosis in many species occurs in the absence of centrosomes, the microtubule organizing centers that nucleate...
This dissertation studies three topics in labor and public economics. The first chapter examines the local economic consequences of prisons using two complementary approaches. The first uses the openings of 230 prisons during the 1990s across the entire United States, and the second uses a quasi-experimental strategy that compares winning...
Electrochemical energy storage devices have become increasingly relevant to the operation and sustainability of the modern world, as proliferation of mobile electronics, renewable electrical energy generators, electrical vehicles, and various high-tech bio-medical sensing device continues. The widespread need of easier to produce, better performing, and multifunctional energy storage materials in...
