Clustering And Multifacility Location With Constraints Via Distance Function Penalty Methods And Dc Programming, Mau Nam Nguyen, Thai An Nguyen, Sam Reynolds, Tuyen Tran

Mathematics and Statistics Faculty Publications and Presentations

This paper is a continuation of our effort in using mathematical optimization involving DC programming in clustering and multifacility location. We study a penalty method based on distance functions and apply it particularly to a number of problems in clustering and multifacility location in which the centers to be found must lie in some given set constraints. We also provide different numerical examples to test our method.

Rick, Morty, And Absurdism: The Millennial Allure Of Dark Humor, Kim Koltun

The Forum: Journal of History

The purpose of this paper is to investigate the millennial generation’s appeal to dark and absurdist forms of humor, using the show Rick and Morty as a primary example. I first establish my definition of Absurdism—based on Nagel and Camus—and how Rick and Morty qualifies as an Absurdist work. I then go on to outline the popularity of the show among millennial audiences and explore its allure. There are three important sociological contexts to this explanation: the contrast between upbringing and reality, expedited modernity, and rapidly changing information structures. These set the stage for a distinctive style of humor that …

Assessment Of Spatiotemporal Fusion Algorithms For Planet And Worldview Images, Chiman Kwan, Xiaolin Zhu, Feng Gao, Bryan Chou, Daniel Perez, Jinag Li, Yuzhong Shen, Krzysztof Koperski, Giovanni Marchisio

Electrical & Computer Engineering Faculty Publications

Although Worldview-2 (WV) images (non-pansharpened) have 2-m resolution, the re-visit times for the same areas may be seven days or more. In contrast, Planet images are collected using small satellites that can cover the whole Earth almost daily. However, the resolution of Planet images is 3.125 m. It would be ideal to fuse these two satellites images to generate high spatial resolution (2 m) and high temporal resolution (1 or 2 days) images for applications such as damage assessment, border monitoring, etc. that require quick decisions. In this paper, we evaluate three approaches to fusing Worldview (WV) and Planet images. …

Core And Uncore Joint Frequency Scaling Strategy, Vaibhav Sundriyal, Masha Sosonkina, Bryce Westheimer, Mark Gordon

Electrical & Computer Engineering Faculty Publications

Energy-proportional computing is one of the foremost constraints in the design of next generation exascale systems. These systems must have a very high FLOP-per-watt ratio to be sustainable, which requires tremendous improvements in power efficiency for modern computing systems. This paper focuses on the processor—as still the biggest contributor to the power usage—by considering both its core and uncore power subsystems. The uncore describes those processor functions that are not handled by the core, such as L3 cache and on-chip interconnect, and contributes significantly to the total system power. The uncore frequency scaling (UFS) capability has been available to the …

Square-Root Consider Filters With Hyperbolic Householder Reflections, James S. Mccabe, Kyle J. De Mars

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Maintaining positive definiteness of a filter's error covariance estimate is of paramount importance to any stable and reliable estimation scheme. Two widely used methods for protecting a filter from loss of positive-definiteness are that of consider filtering and square-root filtering. Despite their widespread use in estimation applications, a filtering methodology that combines the two techniques has yet to be presented in a unified, streamlined architecture. This paper develops a new approach to square-root filtering using hyperbolic Householder reflections. A specialization of the method is considered to permit computationally efficient applications, and a numerical example pertaining to a ballistic reentry is …

The Library In The Mountains And The Writing On The Wall : Fragmented Memories And Cultural Amnesia In Ursula K. Le Guin, Erin Michelle Roll

Theses, Dissertations and Culminating Projects

Memory, especially its loss, plays a prominent role in the work of Ursula K. Le Guin (b. 1929). The Telling (2000) and Voices (2006), two of Le Guin’s most recent works, go into great detail on what happens when a memory is lost or destroyed, usually under duress. The former, the last book in Le Guin’s Hainish cycle, deals with a goal to preserve books and learning from a regime that has made it a misguided goal to eradicate all elements of past culture in an effort to modernize the country. In the latter, part of Le Guin’s Annals of …

An Approximation To A Bayesian Detection Statistic For Continuous Gravitational Waves., John J. Bero Iv

Theses

This work concerns Bayesian detection statistics in targeted searches for continuous gravitational waves (GWs). The parameter space for continuous GWs can be divided into 2 groups: amplitude parameters which control the signal strength and phase-evolution parameters which determine its time evolution. A common issue in these searches is dealing with these amplitude parameters which do not affect the phase evolution of the system. The F-statistic maximizes the likelihood function of the data analytically over these parameters, while the B-statistic marginalizes over them. The B-statistic, while potentially more powerful and capable of incorporating astrophysical priors, is not used because of the …

Modeling Of A Dynamic Mckibben Style Muscle System Using Material Properties, Alexander G. Arcus

Theses

The McKibben style artificial muscle is a type of pneumatic artificial muscle. When the muscle is pressurized a length contraction and contractive force occur. Modeling a McKibben style muscle presents many challenges. The physical dynamics of the muscle are highly nonlinear, which makes accurate modeling difficult. Modeling using experimentally determined coefficients enables the creation of an equation that ignores the nonlinear nature of the system, but it can have a limited range or accuracy and cannot adjust for changing system properties. Modeling using the system properties requires the consideration of the nonlinear dynamics of the muscle; however, it provides the …

Using High-Order Prior Belief Predictions In Hierarchical Temporal Memory For Streaming Anomaly Detection, Brody Kutt

Theses

Autonomous streaming anomaly detection can have a significant impact in any domain where continuous, real-time data is common. Often in these domains, datasets are too large or complex to hand label. Algorithms that require expensive global training procedures and large training datasets impose strict demands on data and are accordingly not fit to scale to real-time applications that are noisy and dynamic. Unsupervised algorithms that learn continuously like humans therefore boast increased applicability to these real-world scenarios.

Hierarchical Temporal Memory (HTM) is a biologically constrained theory of machine intelligence inspired by the structure, activity, organization and interaction of pyramidal neurons …

A Monolithic Internal Strain-Gage Balance Design Based On Design For Manufacturability, Thomas Ladson Webb Iii

Mechanical & Aerospace Engineering Theses & Dissertations

This paper proposes an alternative approach to internal strain-gage balance design driven by Design for Manufacturability (DFM) principles. The objective of this research was a reduction in fabrication time and, subsequently, cost of a balance by simplifying its design while maintaining basic stiffness and sensitivity. Traditionally, the National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) balance designs have relied on Electro-Discharge Machining (EDM), which is a precise but slow and, therefore, expensive process. EDM is chosen due to several factors, including material hardness, surface finish, and complex geometry, including blind cuts. The new balance design objectives require no …

Energy-Rich Mesopelagic Fishes Revealed As A Critical Prey Resource For A Deep-Diving Predator Using Quantitative Fatty Acid Signature Analysis, Chandra Goetsch, Melinda G. Conners, Suzanne M. Budge, Yoko Mitani, William A. Walker, Jeffrey F. Bromaghin, Samantha E. Simmons, Colleen Reichmuth, Daniel P. Costa

Biological Sciences Faculty Publications

Understanding the diet of deep-diving predators can provide essential insight to the trophic structure of the mesopelagic ecosystem. Comprehensive population-level diet estimates are exceptionally difficult to obtain for elusive marine predators due to the logistical challenges involved in observing their feeding behavior and collecting samples for traditional stomach content or fecal analyses. We used quantitative fatty acid signature analysis (QFASA) to estimate the diet composition of a wide-ranging mesopelagic predator, the northern elephant seal (Mirounga angustirostris), across five years. To implement QFASA, we first compiled a library of prey fatty acid (FA) profiles from the mesopelagic eastern North Pacific. Given …

Recognizing Addictive Disorders Through Transdiagnostic Assessment, Meagan M. Carr

Master's Theses and Doctoral Dissertations

Some evidence suggests high rates of comorbidity between substance and other related addictive disorders. However, few self-report instruments adopt a transdiagnostic approach, which would be best positioned to answer questions about comorbidity as well as other related phenomenon, such as discontinuation of one type of behavior and initiation of another. The current work aimed to develop a measure that screened for seven types of potentially addictive behavior: alcohol use, drug use, tobacco use, gambling, binge eating, hypersexual behavior, and excessive video game playing. Data were collected at three time-points to develop a large pool of possible items, establish the initial …

Students' Understanding About Clinical Research And Their Willingness To Participate In Clinical Trials, Shashikiran Pathakamudi

Master's Theses and Doctoral Dissertations

Adolescents and young adults remain underrepresented in clinical trials. Knowledge and perceptions related to clinical research usually determine willingness to participate. During the spring of 2016, an in-class paper survey was conducted to determine whether providing a brief introduction to clinical research would affect the willingness of undergraduate students from the College of Arts and Sciences and the College of Technology at Eastern Michigan University to participate in clinical trials. Some participants received information on clinical research through a short paragraph, and some received no new information, which differentiated the “active” group from the “placebo” group. Overall, both groups provided …

Bilateral Deficit: A Comparison Between Upper-Body And Lower-Body Maximal Strength, James Lee Ramsey

Master's Theses and Doctoral Dissertations

Purpose: The study’s primary purpose was to determine if maximal unilateral strength is greater than maximal bilateral strength for the leg press and vertical dumbbell press exercises. The secondary purpose was to determine if blood glucose levels differ between the unilateral and bilateral conditions for the leg press exercise. Methods: Thirty college-aged volunteers reported on two separate occasions, 72 hours apart, for maximal strength testing. Blood glucose was obtained before and after strength testing for the leg press exercise. A paired samples t-test was conducted to determine significance (p < .05). Results: Participants were significantly stronger for the bilateral leg press; however, no significant differences were observed for the vertical dumbbell press exercise. No significant differences were observed in plasma blood glucose for the leg press exercise. Conclusion: Participants did not display a bilateral lateral deficit, which may have been a result of their resistance training prior to the study.

Fear And (Non) Fiction: Agrarian Anxiety In “The Colour Out Of Space”, Antonio Barroso

Master's Theses and Doctoral Dissertations

This literary and sociological study examines H.P. Lovecraft’s “The Colour Out of Space” alongside New England agricultural societies in the late nineteenth and early twentieth centuries as their members faced socio-political change. Anxieties expressed in the short story reflect fears of communities facing erasure at the hands of a reservoir project. Patterns of historical American rural communities facing destruction in the name of progress as well as modern communities facing similar threats show the endurance of Lovecraft’s specific brand of fear.

Mechanically Driven Pendula For Instructional Laboratories, R. M. Pacheco

Master's Theses and Doctoral Dissertations

I present a new, low-cost approach to observing driven resonance with simple and physical pendula. I mount a pendulum on a dynamics cart that is made to oscillate along a horizontal line by a stepper motor and micro-controller. The pendulum pivot therefore has a position that varies sinusoidally with time with a constant, adjustable frequency. I designed and constructed the experiment to be easily implemented into any physics lab. I tested the apparatus and observed driven resonance for both types of pendula. All of the measured resonant frequencies I determined using the apparatus had percent uncertainties under 4% and all …

A mixture of [Emim][EtSO4]-HAN is a potential propellant suitable in a multi-mode chemical-electric microtube-electrospray micro propulsion system. This paper reports experimental mass spectrum results for this liquid when electro sprayed in a 50 μm capillary emitter. Mass spectra from 0-600 amu were obtained over a variety of angles and flow rates from 2 pL/sec to 3 nL/sec in both cation and anion extraction mode. Effects of flow rate and angular orientation on the spectra agree well with literature. Results show at least three of the four monomer species are emitted, along with numerous other species, some of which have been …

Industrial Robot Trajectory Accuracy Evaluation Maps For Hybrid Manufacturing Process Based On Joint Angle Error Analysis, Zhiyuan Wang, Renwei Liu, Todd E. Sparks, Xueyang Chen, Frank W. Liou

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Industrial robots have been widely used in various fields. The joint angle error is the main factor that affects the accuracy performance of the robot. It is important to notice that these kinematic parameters error cannot be eliminated from the robot system completely. Even after calibration, these errors still exist and will be fluctuated during the robot system running. This paper proposed a new method of finding the best position and orientation to perform a specific working path based on the current accuracy capacity of the robot system. By analyzing the robot forward/inverse kinematic and the angle error sensitivity of …

Review Of Metal Am Simulation Validation Techniques, Aaron Flood, Frank W. Liou

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Due to the complexity of metal AM (additive manufacturing), it can require many trial runs to obtain processing parameters which produce a quality build. Because of this trial and error process, the drive for simulations of AM has grown significantly. A simulation only becomes useful to researchers if it can be shown that it is a true representation of the physical process being simulated. Each process being simulated has a different method of validation to show it is an accurate representation of the process. This paper explores the various methodologies for validation of laser-based metal AM simulations, focusing mainly on …

Efficient Inverse Design Of Transonic Airfoils Using Variable-Resolution Models And Manifold Mapping, Xiaosong Du, Leifur Leifsson, Slawomir Koziel

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This paper presents an efficient approach for simulation-based inverse design of airfoil shapes using variable-fidelity computational fluid dynamics models and manifold mapping (MM). Inverse design involves determining an airfoil shape fulfilling a given target performance characteristic. In particular, the pressure coefficient distribution is typically used in aerodynamic inverse design. Such a task can be challenging when using computationally expensive simulations. In the context of local optimization, the MM technique searches for a new design in the vicinity of the current design by constructing a fast multi-fidelity model, which is setup by the available evaluations of each of the high- and …

Estimation Of The Ear Canal Displacement Field Due To In-Ear Device Insertion Using A Registration Method On A Human-Like Artificial Ear, S. Benacchio, O. Doutres, A. Le Troter, A. Varoquaux, E. Wagnac, V. Callot, F. Sgard

Études primaires

Passive and active in-ear devices (IED) occluding the ear canal are commonly used to (i) protect people from high noise levels (earplugs), (ii) assist people suffering from hearing impairment (hearing aids) or (iii) help people in listening from their sound systems (earbuds). However, the usability and/or efficiency of IEDs can be greatly affected by several discomfort components (physical, acoustical and functional). The mechanical pressure exerted by the IED onto the ear canal walls is greatly suspected to affect the aforementioned comfort components. This physical characteristic is closely related to the displacement field induced by the IED insertion, which has to …

Three Essays On Ceo Risk Preferences, And Ability, Corporate Hedging Decisions, And Investor Sentiment, Sonik Mandal

Finance Theses & Dissertations

The derivative hedging research has looked at why firms and how firms hedge and if it increases value for their shareholders. In this dissertation we investigate the relation between CEO risk preferences and ability and whether if affects their hedging decisions and firm value.

In our first essay, we challenge the theory and previous empirical evidence that showed CEO risk preferences affects hedging. Using a sample of Fortune 500 firms and 5 years of panel data, and using inside debt (i.e., CEO pension and deferred compensation) and the CEO Vega and CEO Delta, as proxies of CEO risk preferences, we …
