Rift basin-fill architecture of fluvial-lacustrine Lower Permian Lucaogou and Hongyanchi low-order cycles, Bogda mountains, NW China
(Wichita State University, 2012-07)Rapid lateral facies and thickness changes, autogenic processes, and irregular topography of nonmarine rift basins challenge the application of traditional marine sequence stratigraphic techniques. Stratigraphic architecture ... -
Risk based worker allocation and line balancing
(Wichita State University, 2010-12)In general, manufacturing systems could be classified into machine intensive manufacturing and labor intensive manufacturing. From the previous studies, we can infer that worker allocation plays an important role in ... -
Risk factors that affect test scores, specifically deviant behavior
(Wichita State University, 2009-05)This study attempts to identify the effect that deviance has on high school test scores. Using the Educational Longitudinal Survey, 2002, student role performance, family, peer, and school factors were examined to see ... -
Risk oriented stochastic assembly line balancing
(Wichita State University, 2010-08)In a single model manual assembly line, product flows through series of workstations arranged in a sequential manner. Each workstation has a finite number of tasks and each task has probabilistic processing time. Due to ... -
Robot path planning with sensor feedback for industrial applications
(Wichita State University, 2021-05)The research goal of this study is to investigate the use of sensor feedback for robot path planning and optimization. Robots are ideal automation tools for handling highly repetitive manufacturing tasks with unparalleled ... -
Robotic manta ray propelled by servo actuated pectoral fin
(Wichita State University, 2017-12)Manta Ray is natural sample for lift based propelling robotic fishes. Pectoral fins that exhibit flapping motions are crucial for actuation of bio-mimic robotic Rays. In this research, a two-dimensional maneuverable ... -
Robust and reduced order h-infinity filtering via LMI approach and its application to fault detection
(2006-05)The objective of this dissertation is to develop a practical methodology for designing full and reduced order H[infinity] filter for plants with polytopic model uncertainty. Because the polytopic model description is convex, ... -
Robust PID control using a Smith predictor for time delay systems
(Wichita State University, 2013-12)Time delays are unavoidable in many mechanical and electrical systems. The presence of delay typically imposes strict limitations on achievable feedback performance in both continuous and discrete systems. The presence of ... -
Robust power control design for wind energy in microgrid
(Wichita State University, 2016-12)There has been extensive research concerning wind turbine power generators. However, reducing wind turbine uncertainty in a microgrid with gas turbine and storage has received limited interest. Our objective is to reduce ... -
The role of alcohol expectations in the co-occurrence of alcohol-related problems with anxiety and depressive traits in a juvenile correction sample
(2006-12)Alcohol-related expectations have been defined as the anticipated consequences from consuming alcohol (Brown, Goldman, Inn, & Anderson, 1980). Previous research has been conducted to examine the role of alcohol expectations ... -
The role of altered microRNA expression in an experimental model of estrogen-dependent uterine cancer
(Wichita State University, 2009-07)This project screened for altered expression of small RNA species, microRNAs (miRNA), in the hamster uterus following neonatal exposure to the potent synthetic estrogen and established endocrine disruptor diethylstilbestrol ... -
The role of auxin in the compatible interaction between macrophomina phaseolina and its plant host medicago truncatula
(Wichita State University, 2012-05)Macrophomina phaseolina (M. phaseolina) is a soil-borne fungal pathogen that causes charcoal rot disease in many plant species. This disease causes many problems to the soy industry as no consistently effective control is ... -
Role of Ca2+ and Sodium-Calcium exchanger (NCX) on cellular/mitochondrial uptake and toxicity of the parkinsonian toxin, MPP+
(Wichita State University, 2016-12)Although the exact cause(s) of dopaminergic cell death in Parkinson's disease (PD) is not fully understood, the discovery that 1-methyl-4-phenylpyridinium (MPP+ ) selectively destroys dopaminergic neurons and causes PD ... -
The role of mood on inferential processing
(Wichita State University, 2012-05)The way a reader comprehends a text is influenced by a number of factors; and one factor that may play a critical role is the reader’s mood. The extant literature documents that happy and sad moods elicit different processing ... -
The role of personal epistemology in selection of stuttering treatment
(Wichita State University, 2012-12)Clinicians’ personal epistemology about stuttering and knowledge may directly affect their clinical decision-making process. The purpose of the current study was to obtain a better understanding of the relationship between ... -
The role of the family in chronic victimization by peers
(Wichita State University, 2007-08)This study investigated the relationship of family contextual risk factors to the occurrence of victimization of children by peers, as mediated by parental warmth and communication. Family risk factors were derived from ... -
Rolling pattern and energy requirements when rolling from supine to side-lying on rigid and soft surfaces
(Wichita State University, 2017-12)Rolling is an activity that most people perform repeatedly on a daily basis. Rolling and repositioning oneself in bed serves to improve comfort, circulation, and sleep quality and prevent decubitus ulcers, commonly referred ... -
