Hysteretic Behavior Of Thin-Walled Steel Tubular Columns Under Constant Axial Force And Cyclic Lateral Loading, Qusay A. Al-Kaseasbeh

Theses and Dissertations

Thin-walled steel tubular bridge piers (column refers to “bridge pier” in the subsequent text) with either circular and square box cross sections are becoming an increasingly attractive choice as cantilever bridge piers in severe earthquake regions due to their architectural, structural and constructional advantages. However, thin-walled steel tubular columns are vulnerable to local buckling, global buckling or interaction between both under extreme loading events such as strong earthquakes. This buckling results in a significant strength and ductility degradation, which eventually leads to an early and full collapse of the thin-walled steel tubular columns. The work presented in this dissertation investigates …

The Effect Of Different Dianhydride Precursors On The Synthesis, Characterization And Gas Separation Properties Of Pi And Pbo Derived From Bisapaf, Maram Abdulhakim Qasem Al-Sayaghi

Theses and Dissertations

The current processes used for natural gas separation and purification are considered energy intensive which could potentially be substituted by membrane technology. Aromatic polyimides are considered one of the most viable types of polymers used for the fabrication of membranes for gas separation mainly due to their outstanding properties. Moreover, aromatic polyimides could be thermally rearranged to form another class of polymers called polybenzoxazoles which are characterized by having enhanced gas separation properties. This research aimed to (1) synthesize and characterize three different aromatic polyimides via polycondensation reaction of a diamine (BisAPAF) with three different dianhydride precursors (PMDA, ODPA, BTDA), …

Synthesis And Characterization Of Quasi-Two-Dimensional Chromium Sulfides, Furkan Muhammet Altincicek

Theses and Dissertations

Transition metal dichalcogenides (TMDs) are atomically thin semiconductors of the type MX2 with M being a transition metal and X being a chalcogen atom. TMDs have recently attracted considerable attention because of their novel electronic and optical properties. Many TMDs have been studied except CrS2 because of the challenges in its synthesis. However, the most stable form of chromium sulfides, Cr2S3, chromium (III) sulfide, has been known to exhibit novel properties. For this reason, we studied the possibility of synthesizing thin Cr2S3 to mimic CrS2. We synthesized single phase Cr2S3 in vacuum sealed quartz tubes. The synthesis takes about 5 …

The Relationship Between Cell Phone Use And Motivation To Exercise In College Students, Ryan Eric Doree

Theses and Dissertations

Past research suggests that high cell phone usage is related to sedentary behavior, poor physical fitness, and poor mental health. College students cell phone usage has increased over previous years while physical activity levels have declined, but due to little research, this relationship is still unclear. The purpose of this study was to examine the relationship between college student's smartphone usage, exercise motivation, and physical activity. College students completed an electronic survey (n=157; female = 135; age = 20.01±1.49; BMI = 24.39) that assessed exercise motivation, physical activity, smartphone usage, height and weight (to calculate BMI), depression, anxiety, stress and …

Examining Self-Regulation Of Learning Among Community College Students In Developmental Mathematics Courses, Katrina M. Eberhart

Theses and Dissertations

The ability to self-regulate one’s learning is crucial to the success of all college students, but is particularly important to those who are considered to be underprepared; it puts students on a path towards successful course completion, subsequent course enrollment, and eventual graduation from a postsecondary institution. Those enrolled in remedial coursework are a large portion of students labeled as underprepared. Remedial education is a contentious topic in higher education. Thus, it is critical to investigate the use of classroom strategies to foster a self-regulated environment to support student success in these early classes and move onto the classes needed …

A 3 (imagery group) × 2 (pretest and posttest) repeated measures ANOVA with performance and self-efficacy as the dependent variables was used. Results for performance main effects and interactions were not significant (p > .05); means were lower during posttest than pretest but weren’t considered significant changes. For self-efficacy, there was a significant …

Reproductive Strategies Of Common Eiders (Somateria Mollissima), Samuel Donald Hervey

Theses and Dissertations

Many reproductive strategies exist all with the same goal to maximize fitness. Because reproductive strategies affect fitness directly, there is interest to understand how they are utilized within a population. The two main strategies we focus on for this work related to Common Eiders (Somateria mollissima) are the utilization of conspecific brood parasitism as an alternative tactic beyond simply nesting and their ability to shift timing of breeding to align young with the best opportunity for survival. To accomplish studying our two reproductive strategies we monitored the Mast and WaWao Common Eider colonies located within Wapusk National Park, Manitoba. Our …

Earthquake Loading Effects On The Buckling Of Liquid Filled Cylindrical Storage Tanks, Hailey Johnson

Each cylindrical tank modeled had a constant thickness of 0.36 inches. ANSYS Workbench was used to create a finite element analysis of each cylindrical tank. A transient dynamic bucking analysis was performed on each model in order to determine the dynamic buckling load of the cylindrical …

Freedom To Hack, Ido Kilovaty

Articles, Chapters in Books and Other Contributions to Scholarly Works

Swaths of personal and nonpersonal information collected online about internet users are increasingly being used in sophisticated ways to manipulate them based on that information. This represents a new trend in the exploitation of data, where instead of pursuing direct financial gain based on the face value of the data, actors are seeking to engage in data analytics using advanced artificial intelligence technologies that would allow them to more easily access individuals’ cognition and future behavior. Although in recent years the concept of online manipulation has received some academic and policy attention, the desirable relationship between the data-breach law and …

Antennas And Wave Propagation In Wireless Body Area Networks: Design And Evaluation Techniques, Ala Alemaryeen

Theses and Dissertations

Recently, fabrication of miniature electronic devices that can be used for wireless connectivity becomes of great interest in many applications. This has resulted in many small and compact wireless devices that are either implantable or wearable. As these devices are small, the space for the antenna is limited. An antenna is the part of the wireless device that receives and transmits a wireless signal. Implantable and wearable antennas are very susceptible to harmful performance degradation caused by the human body and very difficult to integrate, if not designed properly. A designer need to minimize unwanted radiation absorption by the human …

Acute Effects Of Ballistic And Non-Ballistic Bench Press On Plyometric Push-Up Performance, David Bodden, Timothy J. Suchomel, Alexandra Lates, Nicholas G. Anagnost, Matthew F. Moran, Christopher Taber

Exercise Science Faculty Publications

The purpose of this study was to examine the effects of a ballistic or non-ballistic concentric-only bench press (COBP) on subsequent plyometric push-up performance. Fourteen resistance trained men completed two separate one-repetition-maximum (1RM) testing sessions followed by three randomized experimental explosive push-up sessions. These sessions combined a heavy concentric bench press with plyometric push-ups. Using a series of 3 × 10 (condition × time) repeated measures ANOVA, comparisons were made between the effects of ballistic and non-ballistic bench presses on performance of plyometric push-ups to investigate push-up performance variables. Compared with the control condition, both ballistic and non-ballistic bench presses …

Implementing And Evaluating A Gaussian Mixture Framework For Identifying Gene Function From Tnseq Data, Kevin Li, Rachel Chen, William Lindsey, Aaron Best, Matthew Dejongh, Christopher Henry, Nathan L. Tintle

Faculty Work Comprehensive List

The rapid acceleration of microbial genome sequencing increases opportunities to understand bacterial gene function. Unfortunately, only a small proportion of genes have been studied. Recently, TnSeq has been proposed as a cost-effective, highly reliable approach to predict gene functions as a response to changes in a cell's fitness before-after genomic changes. However, major questions remain about how to best determine whether an observed quantitative change in fitness represents a meaningful change. To address the limitation, we develop a Gaussian mixture model framework for classifying gene function from TnSeq experiments. In order to implement the mixture model, we present the Expectation-Maximization …

Leveraging Summary Statistics To Make Inferences About Complex Phenotypes In Large Biobanks, Angela Gasdaska, Derek Friend, Rachel Chen, Jason Westra, Matthew Zawistowski, William Lindsey, Nathan L. Tintle

Faculty Work Comprehensive List

As genetic sequencing becomes less expensive and data sets linking genetic data and medical records (e.g., Biobanks) become larger and more common, issues of data privacy and computational challenges become more necessary to address in order to realize the benefits of these datasets. One possibility for alleviating these issues is through the use of already-computed summary statistics (e.g., slopes and standard errors from a regression model of a phenotype on a genotype). If groups share summary statistics from their analyses of biobanks, many of the privacy issues and computational challenges concerning the access of these data could be bypassed. In …

Secure Networked Control Via Software Rejuvenation, Paul Griffioen, Raffaele Romagnoli, Bruce H. Krogh, Bruno Sinopoli

Faculty Work Comprehensive List

Software rejuvenation has been proposed as a prevention mechanism against unanticipated and undetectable attacks on cyber-physical systems. Without needing to implement any detection algorithm, the system is periodically refreshed with a secure and trusted copy of the control software to eliminate any malicious modifications to the run-time code and data that may have corrupted the controller. Previous work has considered using software rejuvenation while being able to disconnect from the network when recovering from dangerous situations. In contrast, we consider using software rejuvenation in cases where a network connection is needed in order for proper recovery to occur. We present …

A Proof-Of-Mechanism Study To Test Effects Of The Nmda Receptor Antagonist Lanicemine On Behavioral Sensitization In Individuals With Symptoms Of Ptsd, Marijn Lijffijt, Charles E Green, Nicholas Balderston, Tabish Iqbal, Megan Atkinson, Brittany Vo-Le, Bylinda Vo-Le, Brittany O'Brien, Christian Grillon, Alan C Swann, Sanjay J Mathew

Faculty, Staff and Students Publications

Background: Individuals with post-traumatic stress disorder (PTSD) have a heightened sensitivity to subsequent stressors, addictive drugs, and symptom recurrence, a form of behavioral sensitization. N-methyl-D-aspartate receptors (NMDARs) are involved in the establishment and activation of sensitized behavior.

Objective: We describe a protocol of a randomized placebo-controlled Phase 1b proof-of-mechanism trial to examine target engagement, safety, tolerability, and possible efficacy of the NMDAR antagonist lanicemine in individuals with symptoms of PTSD (Clinician Administered PTSD Scale [CAPS-5] score ≥ 25) and evidence of behavioral sensitization measured as enhanced anxiety-potentiated startle (APS; T-score ≥ 2.8).

Methods: Subjects (n = 24; age range 21–65) …

Incremental theories of intelligence examine the beliefs individuals hold of knowledge and how it is attained. An individual with an incremental theory of intelligence believes that intelligence can be developed. The research examined differences by gender in mastery of statistics and attitudes toward statistics for students who received growth mind-set training. A pre-test, post-test design utilised the Students’ Attitudes Toward Statistics© instrument and the Comprehensive Assessment of Outcomes in a first Statistics course. An …

Orgasm Beyond Genitals: A Critical Study Of The Gender Orgasm Gap, Roni Wiener

Theses & ETDs

Women experience orgasm less frequently than men, a phenomenon known as the gender orgasm gap. Social explanations for this gap connect it to cultural norms that privilege men’s pleasure and preferences. In this thesis, I employ practices from Critical Sexuality Studies to consider how narrow definitions of sex contribute to orgasm disparities. I destabilize heteronormative ideals by centering experiences of orgasm with no genital stimulation (orgasm WNGS). I conducted a quantitative study of orgasm frequencies using an anonymous online survey with a convenience and snowball sample. Participants (N = 388) were between the ages of 18 and 71 (M = …

Educating For Ecological Responsibility: Bernard Lonergan, Pope Francis, And A Local Case Study Prompted By A Global Reality, Jame Schaefer

Theology Faculty Research and Publications

Bernard Lonergan’s philosophy of knowing and Pope Francis’s magisterial teachings yield a complementary trajectory toward educating for ecological responsibility. A concrete example was demonstrated by students in the capstone seminar required for the Interdisciplinary Minor in Environmental Ethics (INEE) at Marquette University in Spring 2017. After exploring Lonergan’s explanation of responsibility, his philosophy of education in which he underscores the need to integrate different ways of knowing, and the pope’s call for “integral ecology” when addressing and acting on ecological problems, the INEE seminar and its outcomes are described. They demonstrate local ways in which individuals and their religious communities …

Link Rot, Reference Rot, And Link Resolvers, Justin White

University Library Publications and Presentations

From the earliest days of the web, users have been aware of the fickleness of linking to content. In some ways, 1998 was a simpler time for the Internet. In other ways, like basic website design principles, everything old is new again. Jakob Nielson, writing “Fighting Linkrot” in 1998, reported on a then-recent survey that suggested 6% of links on the web were broken. The advice then hasn’t changed: run a link validator on your site regularly, and update or remove broken links. Also set up redirects for links that do change. The mantra for Nielson was “you are not …

What Does Kinematical Target Mass Sensitivity In Dis Reveal About Hadron Structure?, E. Moffat, T. C. Rogers, W. Melnitchouk, N. Sato, F. Steffans

Physics Faculty Publications

We study the role of purely external kinematical approximations in inclusive deep-inelastic lepton–hadron scattering within QCD factorization, and consider factorization with an exact treatment of the target hadron mass. We discuss how an observed phenomenological improvement obtained by accounting for target mass kinematics could be interpreted in terms of general properties of target structure, and argue that such an improvement implies a hierarchy of nonperturbative scales within the hadron.

The Evolution Of Technology In Call Centers, Julieo Stephen Thompson

CCAC Theses and Dissertations

Historical research was conducted through literature. The report traces the evolution of technology in call centers (CCs) from their early inception to 2018. CCs are integrated into many facets of multidisciplinary areas of business, industry, and public and private institutions of higher education. Three research questions were addressed:

1. What technologies enabled the start of CCs? How did the communications between customers and CSRs take place? What was the content of the earlier communications?
2. How did services and communications evolve as technology matured?
3. What are the current state-of-the-art technologies that exist in CCs? Which industries appear to have the best solutions? …

Insulin pumps are designed for the self-management of diabetes mellitus in patients and are known for their complexity of use. Pump manufacturers engage trainers to teach patients how to use the devices correctly to control the symptoms of their disease. Usability research related to insulin pumps and other infusion pumps with first-time users as participants has centered on the relationship between user interface design and the effectiveness of task completion. According to prior research, the characteristics of system behavior in a real life environment remain elusive. A suitable approach to acquire information about potential usability problems encountered by first-time users …

The Tailoring Of National Guidelines For Upper Extremity Post-Stroke Rehabilitation: A Concept In Use., Salem F. Alatawi

Internet Journal of Allied Health Sciences and Practice

Background: In Saudi Arabia, national evidence-based clinical guidelines (NCG) were created based for healthcare interventions. However, clinicians appear to be slow to incorporate the evidence into practice. As a result, there exists a time-gap between the gathering and presentation of evidence for best practice and the use of that evidence by clinicians. It becomes, therefore, imperative to investigate the gap between the research evidence and clinical practice. The knowledge to action (KTA) framework is available to facilitate the implementation of research evidence. This framework incorporates the theory of tailoring, a concept that is intended to create a fit between …
