A Hybrid Algorithm Based On Seeker Optimization Algorithm And Salp Swarm Algorithm For Pid Parameters Optimization, Shaomi Duan, Huilong Luo, Haipeng Liu

Journal of System Simulation

Abstract: Aiming at the premature convergence of seeker optimization algorithm(SOA) during optimizing the global problems, a new SOA-SSA hybrid algorithm based on seeker optimization algorithm and salp swarm algorithm (SSA) is proposed.The SOA-SSA algorithm is based on a double population evolution strategy, in which some individuals of the population are evolved by seeker optimization algorithm and the rest are evolved from salp swarm algorithm. The individuals in SOA and SSA both employ an information sharing mechanism to realize the coevolution. These strategies increase the diversity of the population and avoid the premature convergence. The experimental results show that …

Application Of Improved Q Learning Algorithm In Job Shop Scheduling Problem, Yejian Zhao, Yanhong Wang, Jun Zhang, Hongxia Yu, Zhongda Tian

Journal of System Simulation

Abstract: Aiming at the job shop scheduling in a dynamic environment, a dynamic scheduling algorithm based on an improved Q learning algorithm and dispatching rules is proposed. The state space of the dynamic scheduling algorithm is described with the concept of "the urgency of remaining tasks" and a reward function with the purpose of "the higher the slack, the higher the penalty" is disigned. In view of the problem that the greedy strategy will select the sub-optimal actions in the later stage of learning, the traditional Q learning algorithm is improved by introducing an action selection strategy based on the …

Needs Assessment Of Services Provided In A Rural School District For Students With Autism, Danielle Anne Katterman

Theses and Dissertations

The number of children diagnosed with autism spectrum disorder (autism) has steadily increased dramatically over the past generation, and more students with autism than ever before are enrolled in the public education system. Educating students with autism presents unique challenges (e.g., shortage of staff, low incidence of autism, limited programming) to rural school districts. Rural districts must adhere to the same federal and state guidelines (e.g., Individuals with Disabilities Education Act & Free and Appropriate Public Education) as urban districts that have more readily available resources in providing appropriate programming. This study examined stakeholders' perceptions of the current services offered …

Facilitators And Barriers To Farmers’ Market Use In A Rural Area, Soghra Jarvandi, Kristen Johnson, Karen Franck

Journal of Extension

Farmers’ markets may improve access to healthful foods in rural areas. Our objective was to identify facilitators and barriers to farmers’ market use in a rural county. We collected data via surveys, focus group sessions, and key informant interviews. Study participants identified the two existing farmers’ markets as community assets. Barriers to use farmers’ markets included inconvenient market hours, not accepting nutrition assistance program benefits, limited transportation, and limited variety. Interventions to improve food access should include ways to meet the needs of specific populations such as low-income residents and residents living in outlying areas without farmers’ markets.

Student Prior Knowledge And Learning In An Intelligent Tutoring System: Comparing The Effectiveness Of Vicarious And Interactive Dialogues, Keith Thomas Shubeck

Electronic Theses and Dissertations Archive

Intelligent tutoring system (ITS) developers often assume that the system’s effectiveness is driven by its interactivity, and for good reason; research regularly shows that interactivity is a critical component for learning. However, some evidence suggests that students with low prior knowledge learn best in vicarious settings, or in settings where they can model a peer agent’s positive learning behaviors. The expertise reversal effect suggests that high prior knowledge students may not benefit from the increased granularity and interactivity that a conversation-based ITS can provide. In the current study, participants were randomly placed into an interactive condition where they interacted with …

Hit By Cupid's Arrow: Hidden Violence In Love Metaphors, Isis Dornbrook

Anthós

Love is an emotion that typically brings joy. However, the ways in which society talks about love suggest otherwise. The process of metaphor analysis makes the violence in societal expressions of love salient. Additionally, metaphor analysis shows that violent metaphors can inform the way people interact with one another throughout the stages of relationship formation, such as using metaphors to justify sexual and other types of physical abuse. Thus, this paper argues that metaphors, by shaping our attitudes and expectations about love, sex, and relationships, have observable social and cultural implications.

Passing Down: Nella Larsen's Questioning Of Eugenic Ideology, Sky R. Mcleod

Anthós

This article looks at Nella Larsen’s 1929 novel Passing and examines how eugenic ideology of the time period are explored and critiqued through the story and characters. The novel follows two light skinned black women who grew up together and are reunited as adults. This reconciliation takes place under the backdrop of the Harlem Renaissance where the expectations of New Negro womanhood mix with a growing wave of eugenic thought and practices. In the 1920’s many influential thinkers, including black leaders such as W. E.B. Du Bois, were convinced that the only way to move the human race forward was …

The Passive Approach: How Academically Motivated Students Approach Their Mental Health., Megan E. Mccoy

Anthós

The research utilizes qualitative interviews and focus groups to understand how academically motivated students approach their mental health. Mental health is defined as “emotional, psychological, and social well-being,” by the Center for Disease Control and Prevention and is becoming a more significant concern in collegiate student populations. At Portland State University, the effects of mental health concerns on students are nearly double that of students around the U.S (Community Commons, n.d.). Academically motivated students are a group who seemingly strive for success and likely experience high levels of stress daily. The study found that students often take a passive approach …

Glucose Homeostasis In Human Diabetic Adipocytes: Role Of Glp1 In Sortilin Alternative Splicing, Ashley Lui

USF Tampa Graduate Theses and Dissertations

Type 2 diabetes mellitus (T2DM) is a chronic and progressive metabolic disease defined by systemic insulin resistance. The inability of cells to respond to insulin and take up glucose results in elevated blood sugar that is detrimental to the overall health of patients. There is no cure for T2DM. Identification of new targets to alleviate hyperglycemia are crucial for treatment and prevention of metabolic diseases. Adipocytes play a central role in glycemic regulation by insulin stimulated glucose uptake, storage of excess nutrients, and secretion of adipokines. Major glucose transporter-4 (Glut4) is the main transporter responsible for postprandial clearance of glucose …

Analytic Solution Of 1d Diffusion-Convection Equation With Varying Boundary Conditions, Małgorzata B. Glinowiecka-Cox

University Honors Theses

A diffusion-convection equation is a partial differential equation featuring two important physical processes. In this paper, we establish the theory of solving a 1D diffusion-convection equation, subject to homogeneous Dirichlet, Robin, or Neumann boundary conditions and a general initial condition. Firstly, we transform the diffusion-convection equation into a pure diffusion equation. Secondly, using a separation of variables technique, we obtain a general solution formula for each boundary type case, subject to transformed boundary and initial conditions. While eigenvalues in the cases of Dirichlet and Neumann boundary conditions can be constructed easily, the Robin boundary condition necessitates solving a transcendental algebraic …

Understanding of these mechanisms is then used to support probiotics, fecal microbiota transplants, and regulated sleep schedules …

Neuroscience-Informed Self-Advocacy For Individuals With Psychiatric Disorders, Britta Harbury

University Honors Theses

Self-advocacy is an effective way to foster improved quality of care for people with psychiatric illnesses. By understanding their conditions and needs they are better able to collaborate with their clinicians and form effective treatment plans. Introducing basic neuroscience to individuals with mental illnesses equips them to navigate the American mental healthcare system, which relies on neuroscience to create diagnoses and medications. This thesis aims to create neuroscience-informed mental health resources so that individuals with psychiatric disorders can access information that may help them better advocate for themselves in the future.

Michigan Conifer Growers’ Perspectives On Disease Management, Emily S. Huff, Monique L. Sakalidis

Journal of Extension

A survey of commercial nursery and Christmas tree growers was implemented online and by mail in 2018 to understand disease issues and information preferences. Overall, the majority of the respondents reported that they prefer online sources of information and many are using Extension bulletins and sources. Cultural, chemical, and weed control methods were considered extremely effective by participants and very few used biological control methods to control disease. Participants identified spruce decline, boxwood blight, and hemlock woolly adelgid as emerging disease threats, so future information to growers should focus on identification and management of these threats.
