Conflict, Climate, And Child Health: Evidence From Sub-Saharan Africa, Brian C. Thiede, Nigel C. James

Health Studies Faculty Publications

Many parts of the world are experiencing social and political instability, as well as ongoing climatic changes that are expected to accelerate in the years ahead. These changes can undermine children's health through multiple pathways, and the growing frequency of sociopolitical and environmental stressors increases the likelihood that individuals are exposed to multiple risks simultaneously. Few studies have quantified the effects of such concurrent shocks despite conceptual motivations for doing so. We address this gap by measuring the independent and compounding effects of conflict and climate exposures on the weight-for-height of 0–23 month-old children across 32 countries in sub-Saharan Africa. …

Frye Is So Last Century: It’S Time For Washington To Get With The Times, Darian Mullen

Seattle Journal of Technology, Environmental, & Innovation Law

This paper argues that Washington State should finally abandon the

Frye test for expert witnesses and adopt the Daubert test used by federal

courts and most states. It begins with a discussion of the background of

expert witnesses in the U.S. court system and its evolution through Frye.

Then, it looks at the increase in drunk driving in Washington State as a

case study for how the public depends on quality science to protect

individuals and punish wrongdoers. Through the case study, it is

apparent that Frye is an unworkable standard that should be superseded

by Daubert.

Classification Of Hif Detection In Nev Profile Using Wavelet Transform And Convolution Neural Network, Abdul Hafiz Kassim, Mohd Abdul Talib Mat Yusoh, Aster Smith Valentinie Wilson Nottelmarc, Ahmad Farid Abidin, Sim Sy Yi, Daw Saleh Sasi Mohammed

Turkish Journal of Electrical Engineering and Computer Sciences

High impedance faults (HIFs) present a critical challenge in power systems due to their subtle signal characteristics, which often remain undetected by conventional protection methods. These faults typically do not produce significant phase disturbances, making reliable detection difficult. However, analysis of the neutral-to-earth voltage (NEV) profile under fault conditions provides a promising alternative for fault identification. Existing approaches for detecting and classifying HIFs using NEV signals remain limited and may result in inaccurate maintenance decisions. This paper proposes a fault classification framework for multiple fault types, including HIF, three-phase fault, three-phase fault to ground, double line, double line to ground, …

Complex-Valued Convolutional Neural Network With Time-Frequency Representation For Electrocardiogram-Based Arrhythmia Detection, Kajeeth Kumar Gurusamy, Muthurajkumar Sannasy

Turkish Journal of Electrical Engineering and Computer Sciences

This research proposes an end-to-end procedure for arrhythmia detection based on electrocardiogram (ECG) signals using complex-valued convolutional neural network (CVCNN) incorporated with time-frequency representation. The proposed model leverages complex numbers to capture amplitude and phase information that enhances the ability of the model for detecting time-frequency variation in cardiac signals. First, signal preprocessing techniques---including normalization, wavelet denoising, and R-peak detection---are applied. Subsequently, the model extracts complex features from raw ECG data by employing the Hilbert transform to derive the analytic signal and the short-time Fourier transform (STFT) to generate a time–frequency representation. The proposed CVCNN framework effectively learns spatial-temporal features …

Adaptive Backstepping Nonsingular Fast Terminal Sliding Mode Control For Robotic Manipulators Based On Disturbance Observer, Xin Zhang, Xu Wang

Turkish Journal of Electrical Engineering and Computer Sciences

This paper presents an adaptive backstepping nonsingular fast terminal sliding mode controller integrated with a nonlinear disturbance observer to achieve precise trajectory tracking of robotic manipulators subject to model uncertainties and unknown time-varying disturbances. A dead-zone–based adaptive gain mechanism is introduced to dynamically adjust the control gain according to the deviation of the sliding surface, thereby enhancing robustness and reducing chattering. The proposed reaching law ensures fast, nonsingular, and adaptive convergence, suppressing high-frequency oscillations without compromising stability and the nonlinear disturbance observer enables real-time estimation and compensation of modeling errors, friction, and external disturbances for superior rejection. The semiglobal uniform …

Chaotic Artificial Bee Colony-Optimized Stacking Ensemble For Robust Multifault Diagnosis Of Wind Turbines, Veilraj Revathi, Solaimalai Jeyadevi, Madasamy Sudalaimani

Turkish Journal of Electrical Engineering and Computer Sciences

The complex electromechanical structure of wind turbines, along with harsh operating conditions, poses significant challenges for precise and robust fault diagnosis. To address this challenge, an ensemble multifault diagnostic framework based on an adaptive chaotic artificial bee colony (C-ABC)-optimized support vector machine (SVM) and gradient boosting machine (GBM) is proposed. In the proposed framework, data redundancy and overfitting are reduced through a two-stage hybrid filter-transformer-based feature reduction approach using ReliefF, followed by Principal Component Analysis. The chaos function of the proposed C-ABC maintains an adaptive balance between the exploration and exploitation phases, thereby preventing premature convergence, which is a common …

The Extraction And Chemical Characterization Of The Avian Pigments Turacin And Turacoverdin, Sarah R. Bekkali

Honors Scholar Theses

Bird coloration is a trait that extends beyond mere aesthetics as it has an extensive range of biological significance. Plumage patterns and hues can influence camouflage, mate choice, social dominance, and physiological performance. Bird fitness, their ability to survive and reproduce, is greatly dependent on color. Melanins, carotenoids, and pterins are well-studied pigment systems that are commonly found across many avian species’. Alternatively, porphyrin-based pigments are rare and less-studied as they only found in turacos a sub-Saharan African bird belonging to the family Musophagidae. This thesis focuses on two pigments of interest: turacin, the deep crimson-red pigment found in …

Proximal Stress And Gender Identity: The Role Of Internalized Transphobia In Future Expectations, Maribelle Almonacy

Student Theses and Dissertations

Transgender and non-conforming (TGNC) youth and young adults are more likely to experience symptoms of posttraumatic stress due to identity-specific abuse. Studies on the impact of trauma on negative expectations in high-risk youth show a high association between pessimism, nihilism, and instability. Internalized transphobia, similarly, is correlated with negative mental health outcomes, such as depression and anxiety, and the internalization of social messages and discrimination. These studies are not specific to the experiences of gender minorities and do not explore the intersections of internalized stressors or trauma in young adults. To address this gap in literature, this study sought to …
