Semantics And Result Disambiguation For Keyword Search On Tree Data, Cem Aksoy Jan 2016

Semantics And Result Disambiguation For Keyword Search On Tree Data, Cem Aksoy

Dissertations

Keyword search is a popular technique for searching tree-structured data (e.g., XML, JSON) on the web because it frees the user from learning a complex query language and the structure of the data sources. However, the convenience of keyword search comes with drawbacks. The imprecision of the keyword queries usually results in a very large number of results of which only very few are relevant to the query. Multiple previous approaches have tried to address this problem. Some of them exploit structural and semantic properties of the tree data in order to filter out irrelevant results while others use a …

Plasticity Of The Cortical Representation Of Finger Extensors Induced By Paired Associative Stimulation, Ian Anthony Gerard Lafond Jan 2016

Plasticity Of The Cortical Representation Of Finger Extensors Induced By Paired Associative Stimulation, Ian Anthony Gerard Lafond

Dissertations

This dissertation first explored associative plasticity of the human motor cortical representation with the use of noninvasive transcranial magnetic stimulation (TMS) paired with peripheral electrical stimulation. Paired Associative Stimulation (PAS) has grown in popularity because of its potential clinical applications. PAS techniques are used in combination with electromyography (EMG) measurements to study cortical excitability and features of hand movement. This work focuses on a cohesive approach to answer central questions about: the ideal mechanism to facilitate cortical plasticity via PAS, the interaction between the behavior performed and type of stimulation delivered to the targeted cortical network and the effects of …

Generalized Dft: Extensions In Communications, Yuewen Wang Jan 2016

Generalized Dft: Extensions In Communications, Yuewen Wang

Dissertations

Discrete Fourier Transform (DFT) is a restricted version of Generalized DFT (GDFT) which offers a very limited number of sets to be used in a multicarrier communication system. In contrast, as an extension on Discrete Fourier Transform (DFT) from the linear phase to non-linear phase, the proposed GDFT provides many possible carrier sets of various lengths with comparable or better performance than DFT. The availability of the rich library of orthogonal constant amplitude transforms with good performance allows people to design adaptive systems where user code allocations are made dynamically to exploit the current channel conditions in order to deliver …

Task-Based User Profiling For Query Refinement (Toque), Chao Xu Jan 2016

Task-Based User Profiling For Query Refinement (Toque), Chao Xu

Dissertations

The information needs of search engine users vary in complexity. Some simple needs can be satisfied by using a single query, while complicated ones require a series of queries spanning a period of time. A search task, consisting of a sequence of search queries serving the same information need, can be treated as an atomic unit for modeling user’s search preferences and has been applied in improving the accuracy of search results. However, existing studies on user search tasks mainly focus on applying user’s interests in re-ranking search results. Only few studies have examined the effects of utilizing search tasks …

Engaging Diverse Students In Statistical Inquiry: A Comparison Of Learning Experiences And Outcomes Of Under-Represented And Non-Underrepresented Students Enrolled In A Multidisciplinary Project-Based Statistics Course, Lisa Dierker (Ae), Jalen Alexander, Jennifer L. Cooper, Arielle Selya, Jennifer Rose, Nilanjana Dasgupta

International Journal for the Scholarship of Teaching & Learning

Introductory statistics needs innovative, evidence-based teaching practices that support and engage diverse students. To evaluate the success of a multidisciplinary, project-based course, we compared experiences of under-represented (URM) and non-underrepresented students in 4 years of the course. While URM students considered the material more difficult than non-URM students, URM students demonstrated similar levels of increased confidence in applied skills and interest in follow up courses as non-URM students. URM students were found to be twice as likely as non-URM students to report that their interest in conducting research increased. Increasing student confidence and interest gives all students a welcoming place …

Does Comparing Informal And Formal Procedures Promote Mathematics Learning? The Benefits Of Bridging Depend On Attitudes Toward Mathematics, Shanta Hattikudur, Pooja G. Sidney, Martha W. Alibali Jan 2016

Does Comparing Informal And Formal Procedures Promote Mathematics Learning? The Benefits Of Bridging Depend On Attitudes Toward Mathematics, Shanta Hattikudur, Pooja G. Sidney, Martha W. Alibali

The Journal of Problem Solving

Students benefit from learning multiple procedures for solving the same or related problems. However, past research on comparison instruction has focused on comparing multiple formal procedures. This study investigated whether the benefits of comparing procedures extend to comparisons that involve informal and formal procedures. We also examined how learner characteristics, including prior knowledge and attitudes toward mathematics, affect learning from comparing procedures. We addressed these issues in college students' learning procedures for solving systems of equations problems in algebra. Learners who liked mathematics learned equally well whether they received comparison or sequential instruction. However, among learners who did not like …

Alternative Representations In Algebraic Problem Solving: When Are Graphs Better Than Equations?, Marta K. Mielicki, Jennifer Wiley Jan 2016

Alternative Representations In Algebraic Problem Solving: When Are Graphs Better Than Equations?, Marta K. Mielicki, Jennifer Wiley

The Journal of Problem Solving

Successful algebraic problem solving entails adaptability of solution methods using different representations. Prior research has suggested that students are more likely to prefer symbolic solution methods (equations) over graphical ones, even when graphical methods should be more efficient. However, this research has not tested how representation format might affect solution success, and whether the efficiency of solution varies depending on the nature of the problem solving task. This study addressed the question of whether symbolic or graphical representation format provides different affordances with respect to two different types of problems: computation and interpretation. Graphical representation was found to facilitate problem …

Research In Brief - Can They Teach Each Other? : The Restructuring Of Higher Education And The Rise Of Undergraduate Student “Teachers” In Ontario, Jennifer Massey, Sean Field Jan 2016

Research In Brief - Can They Teach Each Other? : The Restructuring Of Higher Education And The Rise Of Undergraduate Student “Teachers” In Ontario, Jennifer Massey, Sean Field

Journal of Critical Scholarship on Higher Education and Student Affairs

Changes to public funding regimes, coupled with transformations in how universities are managed and measured have altered the methods for educating undergraduate students. The growing reliance on teaching fellows, teaching assistants, and increasingly undergraduate peer educators (administering Supplemental Instruction [SI] programs) is promoted as a means toachieve a greater “return on investment” in the delivery of postsecondary education. Neoliberal discourses legitimating this downloading of teaching labour suggest it offers a “win-win” solution to the “problem” of educating growing numbers of undergraduate students. It proposes universities can deliver the same curricula, and achieve the same “outcomes” (primarily measured through grades and …

Distributed Visualization Of Gridded Geophysical Data: The Carbon Data Explorer, Version 0.2.3, Kevin Arthur Endsley, Michael G. Billmire

Michigan Tech Research Institute Publications

Due to the proliferation of geophysical models, particularly climate models, the increasing resolution of their spatiotemporal estimates of Earth system processes, and the desire to easily share results with collaborators, there is a genuine need for tools to manage, aggregate, visualize, and share data sets. We present a new, web-based software tool – the Carbon Data Explorer – that provides these capabilities for gridded geophysical data sets. While originally developed for visualizing carbon flux, this tool can accommodate any time-varying, spatially explicit scientific data set, particularly NASA Earth system science level III products. In addition, the tool's open-source licensing and …

Integrating Hot And Cool Intelligences: Thinking Broadly About Broad Abilities, W. Joel Schneider, John D. Mayer, Daniel A. Newman Jan 2016

Integrating Hot And Cool Intelligences: Thinking Broadly About Broad Abilities, W. Joel Schneider, John D. Mayer, Daniel A. Newman

Psychology

Although results from factor-analytic studies of the broad, second-stratum abilities of human intelligence have been fairly consistent for decades, the list of broad abilities is far from complete, much less understood. We propose criteria by which the list of broad abilities could be amended and envision alternatives for how our understanding of the hot intelligences (abilities involving emotionally-salient information) and cool intelligences (abilities involving perceptual processing and logical reasoning) might be integrated into a coherent theoretical framework.

Feminist-In-Chief? Examining President Obama's Executive Orders On Women's Rights Issues, Mary Pat Treuthart Jan 2016

Feminist-In-Chief? Examining President Obama's Executive Orders On Women's Rights Issues, Mary Pat Treuthart

Chicago-Kent Law Review

This article focuses on President Obama’s use of executive orders in various areas of women’s rights issues including the empowerment of women, gender-based violence, reproductive rights, and employment. As scholars of the American presidency have noted, executive orders can be used either as strategic tools to short-circuit legislative gridlock or to underscore and complement presidential policy measures pending in Congress. Executive orders can also serve to promote projects of special interest groups. Finally, knowing that their directives can be powerfully symbolic, presidents can be particularly effective in the use of executive action to underscore the gulf between the Democratic Party …

Key Management Scheme Based On Route Planning Of Mobile Sink In Wireless Sensor Networks, Ying Zhang, Jixing Liang, Bingxin Zheng, Shengming Jiang, Wei Chen Jan 2016

Key Management Scheme Based On Route Planning Of Mobile Sink In Wireless Sensor Networks, Ying Zhang, Jixing Liang, Bingxin Zheng, Shengming Jiang, Wei Chen

Computer Science Faculty Research

In many wireless sensor network application scenarios the key management scheme with a Mobile Sink (MS) should be fully investigated. This paper proposes a key management scheme based on dynamic clustering and optimal-routing choice of MS. The concept of Traveling Salesman Problem with Neighbor areas (TSPN) in dynamic clustering for data exchange is proposed, and the selection probability is used in MS route planning. The proposed scheme extends static key management to dynamic key management by considering the dynamic clustering and mobility of MSs, which can effectively balance the total energy consumption during the activities. Considering the different resources available …

Growth Control Of Oxygen Stoichiometry In Homoepitaxial Srtio3 Films By Pulsed Laser Epitaxy In High Vacuum, Ho Nyung Lee, Sung S. Ambrose Seo, Woo Seok Choi, Christopher M. Rouleau Jan 2016

Growth Control Of Oxygen Stoichiometry In Homoepitaxial Srtio3 Films By Pulsed Laser Epitaxy In High Vacuum, Ho Nyung Lee, Sung S. Ambrose Seo, Woo Seok Choi, Christopher M. Rouleau

Physics and Astronomy Faculty Publications

In many transition metal oxides, oxygen stoichiometry is one of the most critical parameters that plays a key role in determining the structural, physical, optical, and electrochemical properties of the material. However, controlling the growth to obtain high quality single crystal films having the right oxygen stoichiometry, especially in a high vacuum environment, has been viewed as a challenge. In this work, we show that, through proper control of the plume kinetic energy, stoichiometric crystalline films can be synthesized without generating oxygen defects even in high vacuum. We use a model homoepitaxial system of SrTiO3 (STO) thin films on …

To exploit the full potential of radio measurements of cosmic-ray air showers at MHz frequencies, a detector timing synchronization within 1 ns is needed. Large distributed radio detector arrays such as the Auger Engineering Radio Array (AERA) rely on timing via the Global Positioning System (GPS) for the synchronization of individual detector station clocks. Unfortunately, GPS timing is expected to have an accuracy no better than about 5 ns. In practice, in particular in AERA, the GPS clocks exhibit drifts on the order of tens of ns. We developed a technique to correct for the GPS drifts, and an independent …

We provide a theoretical context for understanding the recent work of Kalfountzou et al. showing that star formation is enhanced at lower optical luminosity in radio-loud quasars. Our proposal for coupling the assumption of collimated FRII quasar-jet-induced star formation with lower accretion optical luminosity also explains the observed jet power peak in active galaxies at higher redshift compared to the peak in accretion power, doing so in a way that predicts the existence of a family of radio-quiet active galactic nuclei associated with rapidly spinning supermassive black holes at low redshift, as mounting observations suggest. The relevance of this work …

Weak Values Are Quantum: You Can Bet On It, Alessandro Romito, Andrew N. Jordan, Yakir Aharonov, Yuval Gefen Jan 2016

Weak Values Are Quantum: You Can Bet On It, Alessandro Romito, Andrew N. Jordan, Yakir Aharonov, Yuval Gefen

Mathematics, Physics, and Computer Science Faculty Articles and Research

The outcome of a weak quantum measurement conditioned to a subsequent post-selection (a weak value protocol) can assume peculiar values. These results cannot be explained in terms of conditional probabilistic outcomes of projective measurements. However, a classical model has been recently put forward that can reproduce peculiar expectation values, reminiscent of weak values. This led the authors of that work to claim that weak values have an entirely classical explanation. Here we discuss what is quantum about weak values with the help of a simple model based on basic quantum mechanics. We first demonstrate how a classical theory can indeed …

Microbial Pretreatment Of Waste For Anaerobic Digestion, Braden Myers, Jaron Hansen Jan 2016

Microbial Pretreatment Of Waste For Anaerobic Digestion, Braden Myers, Jaron Hansen

Journal of Undergraduate Research

The aim of this research was to demonstrate Caldicellulosiruptor bescii is a feasible microbial pretreatment of lignocellulose for enhanced production of biogas when coupled with secondary anaerobic digestion. Before anaerobic digestion of waste can reach its maximum energy production potential, economically sound methods for pretreatments that allow increased digestion of waste materials must be developed. Many types of waste cannot be broken down sufficiently by anaerobic digestion alone. Overcoming this hurdle through successful feedstock pretreatment would unlock a vast potential supply of renewable energy feedstock materials.

Measuring Frequency Noise For Use In Preventing Mode Hops In Extended Cavity Diode Lasers, Mckinley Pugh, Dallin Durfee Jan 2016

Measuring Frequency Noise For Use In Preventing Mode Hops In Extended Cavity Diode Lasers, Mckinley Pugh, Dallin Durfee

Journal of Undergraduate Research

Diode lasers are useful in physics because they are relatively cheap and robust, they are available in a number of wavelengths, and they are tunable. However, because diode lasers have large bandwidths compared to atomic resonances, a reflection grating is added outside the laser. This creates the extended cavity in extended cavity diode lasers (ECDLs) and forces the lasers to operate at a narrower line width, one acceptable for use in atomic physics. Unfortunately, because the ECDL has many factors trying to control the wavelength of the laser (e.g. temperature, current, grating angel and position) small changes in the lasers …

Multi-Class Simultaneous Adaptive Segmentation And Quality Control Of Point Cloud Data, Ayman Habib, Yun-Jou Lin

Lyles School of Civil Engineering Faculty Publications

3D modeling of a given site is an important activity for a wide range of applications including urban planning, as-built mapping of industrial sites, heritage documentation, military simulation, and outdoor/indoor analysis of airflow. Point clouds, which could be either derived from passive or active imaging systems, are an important source for 3D modeling. Such point clouds need to undergo a sequence of data processing steps to derive the necessary information for the 3D modeling process. Segmentation is usually the first step in the data processing chain. This paper presents a region-growing multi-class simultaneous segmentation procedure, where planar, pole-like, and rough …
