A Calderón Preconditioner For The Electric Field Integral Equation With Layered Medium Green's Function, Yongpin P. Chen, Sheng Sun, Lijun Jiang, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

A Calderón preconditioner is developed for the analysis of electromagnetic scattering of perfect electrically conducting (PEC) objects embedded in a layered medium. The electric field integral equation (EFIE) is formulated with the kernel of layered medium Green's function to account for the effects from the multilayered background. The Calderón projector is derived based on the general source-field relationship and the extinction theorem for inhomogeneous environment in electromagnetic theory. The Calderón identities can be naturally deduced based on this projector, which is then leveraged to precondition the EFIE with layered kernel. An alternative implementation is then proposed to make the implementation …

A Rigorous Approach For The Radiated Emission Characterization Based On The Spherical Magnetic Field Scanning, Ping Li, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Electromagnetic radiated emissions from antennas, printed circuit boards (PCBs), and electronic devices are becoming increasingly critical to today's IC electromagnetic compatibility and interference properties. In this paper, a rigorous characterization approach is proposed. The electromagnetic field sampling over a spherical testing surface is applied to obtain the radiated magnetic field of the device under test (DUT) placed at the center of the sampling region. Using the dyadic Green's function (DGF) and Huygens' principle, the transformation from the sampled spherical tangential field to the far field is directly computed without resorting to the conventional inverse algorithm. The DGF considers the existence …

A Hybrid Time-Domain Discontinuous Galerkin-Boundary Integral Method For Electromagnetic Scattering Analysis, Ping Li, Yifei Shi, Li (Lijun) Jun Jiang, Hakan Baǧci

Electrical and Computer Engineering Faculty Research & Creative Works

A scheme hybridizing discontinuous Galerkin time-domain (DGTD) and time-domain boundary integral (TDBI) methods for accurately analyzing transient electromagnetic scattering is proposed. Radiation condition is enforced using the numerical flux on the truncation boundary. The fields required by the flux are computed using the TDBI from equivalent currents introduced on a Huygens' surface enclosing the scatterer. The hybrid DGTDBI ensures that the radiation condition is mathematically exact and the resulting computation domain is as small as possible since the truncation boundary conforms to scatterer's shape and is located very close to its surface. Locally truncated domains can also be defined around …

Thermal-Electromagnetic Analysis Of Infrared Antennas, Edward C. Kinzel, Brian Slovick, James Ginn, Brian Lail, Glenn Boreman

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Antenna-coupled Metal-Oxide-Metal (MOM) diodes have been demonstrated for sensing and proposed for energy harvesting at THz, infrared, and even visible frequencies. The design of the antenna allows engineering of the response of the device with respect to polarization, wavelength and angle of incidence. The classic understanding of the antenna coupled MOM diode is that the electric field generated by the antenna causes electrons to tunnel through the barrier oxide. This is supported by the fact that when the oxide separates metals with different work functions, a properly polarized field can produce an asymmetric tunnel current under zero bias. Losses in …

The Soft-Feedback Isi Canceller-Based Turbo Equalizer For Multilevel Modulations, Huang Lou, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we investigate the soft-feedback equalizer (SFE) proposed by Lopes et al. for multilevel modulations. The SFE is based on InterSymbol interference canceller structure and is compared to both soft-decision feedback turbo equalizer (SDFE) and the exact solution of MMSE linear equalizer (Exact-MMSE-LE) by means of EXIT chart analysis and BER simulations. Interesting results reveal that, for multilevel modulations, the SFE not only exhibits the same low complexity, low SNR threshold and fast convergence as SDFE but also reaches matched filter bound after a large number of iterations. © 2013 Springer Science + Business Media New York.

An Accurate Frame Error Rate Approximation Of Coded Diversity Systems With Non-Identical Diversity Branches, Gang Wang, Jingxian Wu, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents an accurate approximation of the frame error rate (FER) of coded wireless communication systems with receiver diversity, such as single-input multiple-output (SIMO) systems with maximum ratio combining (MRC) or hybrid automatic repeat request (HARQ) systems with Chase combining. The signals at different diversity branches experience independent but non-identically distributed Rayleigh fading. The FER approximation is obtained with a threshold-based method. Specifically, the threshold value, which is critical to the FER approximation accuracy, is modeled as a linear function of the frame length in the log-domain, with the slope and intercept of the linear function determined by the …

Responsive Classroom Ecologies: Supporting Student Inquiry And Rhetorical Awareness In College Writing Courses, Adrienne Jankens

Wayne State University Dissertations

This dissertation describes and analyzes the work of a semester-long teacher research study of inquiry-based and reflective teaching and learning strategies and their impact on students' preparation for future learning. I explore relevant scholarship on knowledge transfer, classroom ecologies, and student agency to set the stage for a discussion of several pedagogical strategies implemented to support students' development of inquiry and responsible rhetorical agency. Data analysis highlights three major arguments: first, that alternative pedagogical approaches like an inquiry approach take careful classroom construction and explicit teacher feedback, though it may seem counterintuitive to the politics behind these progressive approaches, which …

Pathway Profiling Of Replicative And Induced Senescence, Maggie Purcell

Wayne State University Dissertations

Senescence is a permanent withdrawal from cell cycle that occurs naturally in cells in response to the shortening of telomeres. This natural "clock" serves to limit the number of cell divisions and therefore protects the cell from potentially carcinogenic mutations. However, senescence also occurs in response to external stresses to the cell, which is known as induced senescence. This study compares the mechanisms of natural senescence, a response to the shortening of telomeres during replication, with induced senescence by using various drugs to induce senescence: 5-aza-2-deoxycytidine (a demethylating agent), Adriamycin (a chemotherapeutic drug), and H2O2 (an agent causing oxidative stress). …

A Genealogy Of Ecological Rhetoric: Heraclitus, Bacon, Darwin And Huxley, Jared Grogan

Wayne State University Dissertations

This dissertation is a genealogical study of historical intersections between rhetoric and ecology. Studying the works of Heraclitus, Francis Bacon, T.H. Huxley and Darwin as "bridge figures" in the history of rhetoric, science and ecological thought, I examine how their rhetorical theories and strategies (as discursive practices, performances and techniques) form a genealogy that bridges rhetorical and ecological theories and practices. My analysis studies their critical assessments and uses of rhetoric as it intersects with each figure's new investigations into natural philosophy, nature, and evolutionary biology, while drawing out relevant lessons for contemporary ecological and rhetorical thinkers. The main threads …

Critical Experiential Learning And Rhetorical Interventions In New Media Ecologies, Jennifer Niester-Mika

Wayne State University Dissertations

This dissertation puts into conversation new media and network theories with the philosophical writings of John Dewey to reconstruct a more relevant and current approach to critical pedagogy that takes into account the shift in socioeconomic power as we move into a control society comprised of immaterial labor. My chapters tackle three different critical pedagogy dilemmas: the neglect of affect, agency in late-capitalism, and critical literacy in new media ecologies. Each chapter defines the dilemma, offers a theoretical response, and details a possible pedagogical application for the composition classroom.

The Reliability And Validity Of The Thin Slice Technique: Observational Research On Video Recorded Medical Interactions, Tanina Suzanne Foster

Wayne State University Dissertations

The Reliability and Validity of the Thin Slice Technique: Observational Research on Video Recorded Medical Interactions

Introduction: Observational research using the thin slice technique has been routinely incorporated in observational research methods, however there is limited evidence supporting use of this technique compared to full interaction coding. The purpose of this study was to determine if this technique could be reliability coded, if ratings are consistent between the first, second and third slice, and if they are indeed representative of full interactions.

Methods: Three 30-second thin slices were sampled from the beginning, middle and end of a full-length video-recorded …

Technologically-Mediated Writing In The First Year Writing Classroom: Twitter And Immediate Writing, Jason Kahler

Wayne State University Dissertations

A series of assignments in First Year Writing classes at Saginaw Valley State University utilizes social media to address issues of kairos in student writing experiences. The term "immediate writing" is applied to these writing activities which require students to produce polished writing in a specific moment, a different objective than commonly-used impromptu or freewriting. Included are considerations of technologically-mediated writing and the artifacts used to generate it.

Research outputs 2014 to 2021

Mutations in THAP1 result in dystonia type 6, with partial penetrance and variable phenotype. The goal of this study was to examine the nature and expression pattern of the protein product(s) of the Thap1 transcription factor (DYT6 gene) in mouse neurons, and to study the regional and developmental distribution, and subcellular localization of Thap1 protein. The goal was accomplished via overexpression and knock-down of Thap1 in the HEK293T cell line and in mouse striatal primary cultures and western blotting of embryonic Thap1-null tissue. The endogenous and transduced Thap1 isoforms were characterized using three different commercially available anti-Thap1 antibodies and validated …

Disease Interpretations And Response Among Hiv-Positive Mothers, Johanna Debora Imelda

Antropologi Indonesia

Despite the growing number of new cases of HIV and AIDS in Indonesia, the progress of prevention programs has been slow. Low prevelance is always stated as a reason for delaying HIV prevention programs and to justify slow progress in implementation. Prevention programs are moreover based on a high-risk group paradigm. They focus on female sex workers as responsible for the spread of HIV, leading to its stigmatization as a hooker's disease. This article describes how seropositive mothers interpret and respond to HIV and AIDS as women, in light of the fact that most of them have not experienced full-blown …

This paper uses a genre of online Chinese popular fiction known as Web-Game fiction as an entry point for exploring the influence of Massively Multiplayer Online Role Playing Games (MMORPGs) on linear narrative fiction. By offering a thick description of MMORPG gameplay and of gamers’ movements between online and offline worlds, Web-Game fiction narrates and “deinteractivates” the subjective experiences of players as they progress through the levels of online role-playing games. This essay proposes that the genre offers an alternative perspective …

School Violence Perpetrators Speak: An Examination Of Perpetrators Views On School Violence Incidents, Gordon A. Crews

Criminal Justice Faculty Publications

In the last few decades researchers have attempted to determine correlates for school violence. While the number of extreme incidents of school violence remains relatively small, extreme incidents cause the most concern for parents, teachers, law enforcement, and educational administrators. In addition to the fear these types of events cause, they also bring about a great deal of debate regarding proper responses. Some feel that stringent zero tolerance policies are the answer, while others argue for more gun control in society. Some feel that increased counseling and service to young people is the answer, while others argue for the increased …

Exploiting Fluencies: Educational Expropriation Of Social Networking Site Consumer Training, Lucinda Rush, Dylan E. Wittkower

Libraries Faculty & Staff Publications

The idea of the digital native was based on abstraction; when we look in detail at the digital activities of high-school and college students, we see deskilling and consumer training rather than information literacy or technical fluency. Yet that training is still training, and may be adaptable in such a way that it can become a literacy—in, for example, the way militaries have mobilised skill-sets produced through gaming. We too can and should mine the narrow and profit-driven consumer training that emerging adults have undergone for kinds of inquiry and critical engagement for which they may have inadvertently been given …

Heritage language is defined as “an indigenous or immigrant language other than English.” The survey was sent to 15,000 randomly selected participants from the PSU student, staff, and faculty body; over 1,000 responses were collected. There was a 10% response rate with 119 participants self-identified as heritage language speakers and/or learners. These participants are individuals in the PSU community who have ties to their heritage community. The top five heritage languages named …

Activist Investors, Distressed Companies, And Value Uncertainty, Michelle M. Harner, Jamie Marincic Griffin, Jennifer Ivey-Crickenberger

Faculty Scholarship

Hedge funds, private equity firms, and other alternative investment funds are frequently key players in corporate restructurings. Most commentators agree that the presence of a fund can change the dynamics of a chapter 11 case. They cannot agree, however, on the impact of this change—i.e., do funds create or destroy enterprise value? This essay contributes to the dialogue by analyzing data from chapter 11 cases in which funds are in a position to influence the debtor’s exit strategy. The data shed light on what such funds might achieve in chapter 11 cases and the potential implications for debtors and their …

Ignatian Pedagogy And Its Alignment With The New Teacher Bar Exam (Edtpa) And Action Research Frameworks, Suzann Girtz

Jesuit Higher Education: A Journal

Teacher Preparation Programs are subject to increasing demands on their curriculums, with no corresponding increases in contact time or duration of programs. As new high-stakes pre-service teacher assessments come online, programs must prepare candidates for success with them while still honoring other elements, such as research in accelerated graduate programs and university identities through specialized pedagogies. Programs face the challenge of teaching it all, and doing so in a coherent manner. This article addresses the alignment across components of edTPA (pre-service education Teacher Performance Assessment), action research, and Ignatian pedagogy, providing a table that aligns the three frameworks.

Mission, Religion, Religious Studies? Student Perspectives On Courses In Buddhism And Islam At A Jesuit University, Bret Lewis

Jesuit Higher Education: A Journal

In the Fall Semester of 2013, at Loyola University Chicago (LUC), a total of 140 students enrolled in select sections of either Theo 295: Introduction to Islam or Theo 297: Introduction to Buddhism. These students, seeking to fulfill core theology requirements through religious studies courses, were surveyed before and after the semester in an attempt to measure attitudes, and potential changes in attitude, about religion and the study of religion – and how these may connect to the context of Jesuit education. This paper attempts to uncover the relationship between the Jesuit theological underpinnings referenced in the mission statement and …

Accompanying The Student: The Ignatian Pedagogical Paradigm And Prior Learning, Kimberly R. Connor

Jesuit Higher Education: A Journal

At the University of San Francisco’s School of Management (SoM), working adults enrolled in our Bachelor of Science in Management degree completion program participate in a process of experience and reflection that prepares them, as our slogan proclaims, to “change the world from here.” Before our working adult students take a management or business class, they are introduced to a process we call the Interdisciplinary Studies Assessment (ISA), a prior learning opportunity that is distinctive for how it works within an Ignatian Pedagogical Paradigm (IPP) that recognizes that learning is a lifelong journey that can take place in a variety …
