Bio-Inspired Memory Device Based Physical Reservoir Computing System To Solve Temporal And Classification Problems, Md Razuan Hossain

Electronic Theses and Dissertations

In recent years, technological advancements in the field of computing have been limited by the slowing down of Moore’s law, which predicts the doubling of the number of transistors on a microchip every two years. The limitations of traditional solid-state electronics have become increasingly evident, as it is becoming difficult to increase the number of transistors while maintaining their reliability and performance. The breakdown of Dennard Scaling, which describes the power-density relationship in CMOS transistors, and the von Neumann bottleneck, which refers to the limited bandwidth between the central processing unit (CPU) and memory, have further exacerbated the situation. Moreover, …

Study Of Bounds For Effective Moduli Of Polycrystals And Composites Using Variational Principle For Probabilistic Measures, Md. Tofiqul Islam

Wayne State University Dissertations

Tensors that are invariant with respect to subgroups of 3D group of rotations were constructed first by Lokhin and Sedov (J. Appl. Math. Mech. (PMM), 1963, 27, 597-629). In this paper we do one more step and derive formulas for the elastic modulus tensors for all symmetry groups from the Lokhin-Sedov results. The tensor basis obtained in this way has an advantage of being built upon the same tensors that are used in construction of nonlinear tensor functions. One consequence of the formulas derived is that the number of types of anisotropic elastic behaviors is ten. There is a long- …

The Price Of Peace: Military Aid As A Foreign Policy Tool, Anthony Sclafani

Motion Sensors And Instrumentation Based On Electrochemical Redox Reaction, Xiaoce Feng

Wayne State University Dissertations

To detect human body vital physiological signals, an electrochemical wearable sensor and a single-mode artificial mechanoreceptor have been developed and their capabilities to detect cardiorespiratory signals, as well as to detect rapid adaptive and slow adaptive responses have been preliminarily demonstrated. The electrochemical method based on I-/I3- redox couple proves to be a sensitive transduction mechanism. Furthermore, a common gate transimpedance amplifier based on gallium nitride high electron mobility transistor for the mechano-acoustic sensor and the wearable mechanoreceptor was developed. The transistor’s performance at high temperatures has been investigated, and its failure mode at high temperature has been discussed.

Cardiolipin Metabolism Regulates Expression Of Muscle Transcription Factor Myod1 And Muscle Development, Linh Vo

Wayne State University Dissertations

The mitochondrial phospholipid cardiolipin (CL) is critical for numerous essential biological processes, including mitochondrial dynamics and energy metabolism. Mutations in the CL remodeling enzyme TAFAZZIN cause Barth syndrome (BTHS), a life-threatening genetic disorder that results in severe physiological defects, including cardiomyopathy, skeletal myopathy, and neutropenia. Although fatigue is among the most debilitating self-reported symptoms of BTHS patients, the mechanistic links whereby CL deficiencies lead to skeletal myopathy and defective muscle formation are not known. In this thesis, using the TAFAZZIN-knockout (TAZ-KO) mouse myoblast C2C12 model, I aimed to elucidate the mechanism of muscle differentiation defect in these cells. We carried …

The Story Within Lessons: Highlighting Moments Of Student Inquiry, Amanda Huffman Hayes

Indiana STEM Education Conference

The curricular decisions of K-12 mathematics teachers affect student learning. One way to make sense of this is to find the story within the lesson. Writing the story of a lesson by identifying the plot, characters, settings, and actions reveals the questions that drive student mathematical curiosity and inquiry (Dietiker, 2015). Drawing attention to these moments provides a new perspective for teachers as they plan, teach, and reflect on their lessons and work to improve their instruction for their students as they see the possible advantages and disadvantages of the ordering of mathematical tasks. This work extends Dietiker’s thinking through …

The purpose of this article is to assess how, when and where WEAs have been used in US wildfires; whether they comply with guidance set out by Mileti and Sorensen’s Warning …

Public Perceptions Of U.S. Earthquake Early Warning Post-Alert Messages: Findings From Focus Groups And Interviews, Jeannette Sutton, Michele M. Wood, Savanah Crouch, Nicholas A. Waugh

Emergency Preparedness, Homeland Security, and Cybersecurity Faculty Scholarship

In May 2020, a false earthquake alert message was sent to the city of Ridgecrest, CA, in the U.S.A., an area that just 10 months prior had experienced a significant series of earthquake events. The false alert was followed by a post-alert message, indicating that the message was cancelled and under investigation. This event, the first of its kind in the U.S.A., provided an opportunity to learn about public perceptions of the post-alert message, including what individuals understood about the threat and their safety, and what actions they should take as a result. We conducted individual interviews with 40 persons …

You Have To Send The Right Message: Examining The Influence Of Protective Action Guidance On Message Perception Outcomes Across Prior Hazard Warning Experience To Three Hazards, Laura Fischer, David Huntsman, Ginger Orton, Jeannette Sutton

Emergency Preparedness, Homeland Security, and Cybersecurity Faculty Scholarship

A long-term goal for warning message designers is to determine the most effective type of message that can instruct individuals to act quickly and prevent loss of life and/or injury when faced with an imminent threat. One likely way to increase an individual’s behavioral intent to act when they are faced with risk information is to provide protective action information or guidance. This study investigated participant perceptions (understanding, believing, personalizing, deciding, milling, self-efficacy, and response-efficacy) in response to the National Weather Service’s experimental product Twitter messages for three hazard types (tornado, snow squall, dust storm), with each message varying by …

Communicating Hazard Location Through Text And Map In Earthquake Early Warnings: A Mixed Methods Study, Jeannette Sutton, Michele M. Wood, Nicholas A. Waugh, Savanah Crouch

Emergency Preparedness, Homeland Security, and Cybersecurity Faculty Scholarship

The purpose of this research was to examine the effect of presenting hazard location in different formats on key warning message outcomes—understanding, personalizing, believing, deciding, and milling. We conducted two studies using experiment and focus group methods. In the experiment, we compared a standard ShakeAlert earthquake early warning message, which merely implied location, to three enhanced messages that communicated information about the earthquake epicenter via text, map, or a combined text-and-map format. Focus groups explored reactions to warning messages accompanied by different types of maps. Overall, the standard ShakeAlert message was associated with worse message outcomes compared to messages that …

A Hierarchical Approach To Improve The Ant Colony Optimization Algorithm, Bryan J. Fischer

EWU Masters Thesis Collection

The ant colony optimization algorithm (ACO) is a fast heuristic-based method for finding favorable solutions to the traveling salesman problem (TSP). When the data set reaches larger values however, the ACO runtime increases dramatically. As a result, clustering nodes into groups is an effective way to reduce the size of the problem while leveraging the advantages of the ACO algorithm. The method for recombining groups of nodes is explored by treating the graph as a hierarchy of clusters, and modifying the original ACO heuristic to operate on a hypergraph. This method of using hierarchical clustering is significantly faster than the …

Swarm Intelligence For Solving Some Nonlinear Differential Equations, Ahmed Elzaghal, Mohammed Mohammed Elgamal, Ahmed H. Eltanboly

Mansoura Engineering Journal

The Euler method is a well-known numerical technique employed for solving initial value problems of ordinary differential equations. The solution obtained through Euler's method is subject to significant inaccuracies, which tend to amplify with each successive iteration. The Particle Swarm Optimization (PSO) algorithm is a highly effective method for finding optimal solutions to both linear and nonlinear optimization problems. In this particular investigation, the PSO technique was utilized to solve initial value problems associated with ordinary differential equations. The Euler method, on the other hand, employs equidistant grid points to approximate solutions, which can result in significant errors and a …
