Concussion Knowledge In Amateur Motocross, Kristina Miller

College of Graduate Studies: Theses & Dissertations

The Center for Disease Control and Prevention estimated that there are 1.6-3.8 million sports related traumatic brain injuries in the United States annually which occur in both mainstream and extreme sports. Many of these concussions have been associated with collisional sports, like football, but high risk extreme sports, like motocross, also have many opportunities for collisions to occur. Unlike traditional varsity sports motocross races, especially at the amateur level, do not require more than advanced life support at a race in case of emergency situation leaving the amateur rider to recognize and decide on concussion management. Purpose of this study …

Game-Based Learning In The Social Studies Classroom, Shannon Magnacca

Instructional Technology Education Specialist Research Papers

This paper investigates if using computer assisted instruction through game-based learning in the social studies classroom increases student achievement when compared to traditional modes of instruction. The paper also determines if the experimental group was intrinsically motivated to learn more than the control group. The students were sixth graders in a social studies classroom. These students participated in a ten day learning period. Students were given a pretest and posttest, as well as an Intrinsic Motivational Survey. The results of the study can be used to guide educators when planning real world lessons that are computer based.

A New Variable Step-Size Zero-Point Attracting Projection Algorithm, Jianming Liu, Steven L. Grant

Electrical and Computer Engineering Faculty Research & Creative Works

This paper proposes a new variable step-size (VSS) scheme for the recently introduced zero-point attracting projection (ZAP) algorithm. The proposed variable step-size ZAPs are based on the gradient of the estimated filter coefficients' sparseness that is approximated by the difference between the sparseness measure of current filter coefficients and an averaged sparseness measure. Simulation results demonstrate that the proposed approach provides both faster convergence rate and better tracking ability than previous ones. © 2013 IEEE.

Low Complexity Soft-Interference Cancellation Turbo Equalization For Mimo Systems With Multilevel Modulations, Jingxian Wu, Longbao Wang, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a low complexity soft-interference cancellation equalizer (SICE) for the turbo detection of multiple-input multiple-output (MIMO) systems operating in time dispersive channels. The SICE contains three time-invariant linear filters: a feedforward filter, a causal feedback filter and an anti-causal feedback filter. The feedforward filter is designed to suppress the InterSymbol interference (ISI) due to time dispersive channels and the multiplexing interference from multiple transmit antennas. The causal (or anti-causal) feedback filter is developed to remove the residual interference caused by the symbols transmitted before (or after) the symbol under detection. The performance of the proposed SICE is verified …

Fpga Implementation Of Qr Decomposition For Mimo-Ofdm Using Four Cordic Cores, Bing Han, Zengli Yang, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

A low-resource implementation of QR decomposition (QRD) is proposed for MIMO-OFDM systems that employ turbo MMSE-IC (Minimum mean square error interference cancellation) detector. The proposed implementation uses only four CORDIC cores for QR decomposition of complex-valued matrices while existing systolic array architecture requires 15 to 38 CORDIC cores to achieve similar throughput. For 4-by-4 MIMO with 1024 subcarrier OFDM, the turbo MMSE-IC requires 1024 QRD of 4-by-4 complex matrices followed by back substitution. Each matrix QRD is accompanied by rotations of four vectors for the second and subsequent turbo iterations. The proposed architecture implements the multiple vector rotation by multipliers …

Energy And Spectral Efficient Transmissions Of Coded Arq Systems, Jingxian Wu, Gang Wang, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

Energy efficiency (EE) and spectral efficiency (SE) feature one of the most fundamental tradeoffs in communication systems. In this paper, we propose an optimum transmission scheme for coded Type-I automatic repeat request (ARQ) systems to balance the EE-SE tradeoff. The optimization is performed with respect to a new design metric, the normalized EE (NEE), which is defined as the energy per bit normalized by the SE. Minimizing NEE means either reducing the energy per bit or increasing the SE, it thus yields a balanced tradeoff between the two. The system design incorporates a wide range of practical system parameters, such …

Neural Network-Based Adaptive Event-Triggered Control Of Affine Nonlinear Discrete Time Systems With Unknown Internal Dynamics, Avimanyu Sahoo, Hao Xu, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, the design of a neural network (NN) based adaptive model-based event-triggered control of an uncertain single input single output (SISO) nonlinear discrete time system in affine form is presented. The controller uses an adaptive estimator consisting of a single-layer NN not only to approximate the internal dynamics of an affine nonlinear discrete-time system but also to provide an estimate of the state vector during inter event interval. The NN weights of the adaptive NN estimator are tuned in a aperiodic manner at the event trigger instants unlike periodic updates in standard adaptive neural network (NN) control. A …

Adaptive Event-Triggered Control Of A Uncertain Linear Discrete Time System Using Measured Input And Output Data, Avimanyu Sahoo, Hao Xu, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, an adaptive model-based event-triggered control of an uncertain linear discrete time system is developed. Measured input and output vectors and their history are utilized to express the unknown linear discrete-time system as an autoregressive Markov representation (ARMarkov). A novel adaptive model in the form of AR Markov is proposed and an update law is derived in order to estimate parameters of the ARMarkov model at triggered instants unlike periodic updates in standard adaptive control. Lyapunov method is used to derive the event trigger condition, prove boundedness of the parameter vector and asymptotic convergence of the outputs and …

Neural Network-Based Optimal Control Of Mobile Robot Formations With Reduced Information Exchange, Travis Dierks, Bryan Brenner, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

A novel formation control scheme for mobile robots is introduced in the context of leader-follower framework with reduced communication exchange. The dynamical controller inputs for the robots are approximated from nonlinear optimal control techniques in order to track the designed control velocities generated by the kinematic controller. The proposed nonlinear optimal control technique, referred to as adaptive dynamic programming, uses neural networks (NNs) to solve the optimal formation control problem in discrete time in the presence of unknown internal dynamics and a known control coefficient matrix. A modification to the follower's kinematic controller is used to allow the desired formation …

Department of Paediatrics and Child Health

Duplications of the alimentary tract include a variety of cysts, diverticula, and tubular malformations, all believed to have embryological origin. The cysts are most commonly found in children, and the diagnosis is made in infancy in the majority of patients. We report a case of a two-and-a-half year old child, presenting with the history of repeated episodes of haematemesis. Upper GI endoscopy was unremarkable and the chest x-ray showed no pathology. Computed tomography (CT) angiogram revealed soft tissue density lesion in the right chest at the level of T6. Right thoracotomy suggested a cystic mass close to the oesophagus which …

Background: Fast breathing pneumonia is characterized by tachypnoea in the absence of danger signs and is mostly viral in etiology. Current guidelines recommend antibiotic therapy for all children with fast breathing pneumonia in resource limited settings, presuming that most pneumonia is bacterial. High quality clinical trial evidence to challenge or support the continued use of antibiotics, as recommended by the World Health Organization is lacking.

Methods/Design: This is a randomized double blinded placebo-controlled non-inferiority trial using parallel assignment with 1:1 allocation ratio, to be conducted in low income squatter settlements of urban Karachi, Pakistan. Children 2-59 months old with fast …

Examining The Role Of Facilitated Conflict On Student Learning Outcomes In A Diversity Education Course, Sabrina N. Ross

Curriculum, Foundations & Reading: Faculty Publications

Building on the Piagetian concept of disequilibrium (i.e., cognitive conflict) and empirical research documenting relationships between cognitive conflict and transformative learning, this article explores the influence of facilitated conflict (i.e., intentional efforts by the instructor to help students reflect on and work through the intergroup conflict they experienced in the course) on the learning outcomes of female students enrolled in an exploratory diversity education course. Various forms of student writing including free-writing exercises and reflective papers were used in addition to two survey response questions to identify sources of cognitive conflict and assess student learning outcomes. Findings revealed that strategies …
