Robust Load Frequency Control For Multiarea Electrical Power Systems Via Analytical Proportional-Integral-Derivative Plus Second Order Derivative Controller Design, Yavuz Güler, Mustafa Nalbantoğlu, Ibrahim Kaya

Turkish Journal of Electrical Engineering and Computer Sciences

This research presents a proportional-integral-derivative plus second order derivative (PIDD2) controller design based on the Direct Synthesis Method (DSM) for load frequency control (LFC) of interconnected power systems. The parameters of the proposed PIDD2 controller are determined using the DSM, which offers an analytical approach for tuning. The design approaches have been developed specifically for single, two, and three-area power systems, encompassing nonreheated and reheated thermal turbines. In the proposed design method, the best values of PIDD2 controller parameters were found by using a multicriteria objective function that includes the integral of absolute error (IAE) and settling time. In response …

A detailed thermal model of the deep freezer was established using an equivalent resistance–capacitance network representation, enabling precise analysis of temperature dynamics. The sliding mode-based control algorithm dynamically adjusts the compressor’s operating frequency according to temperature deviation, ambient conditions, and time-dependent factors, providing robust performance without requiring parameter retuning for different models. Beyond theoretical-based analysis, a …

Empowering Edge Intelligence Through Reparameterized Lightweight Transformers And Distributed Inference, Hosein Esmaeili, Mohammad Ali Afshar Kazemi, Reza Radfar, Nazanin Pilevari

Turkish Journal of Electrical Engineering and Computer Sciences

Deploying advanced transformer-based models on resource-constrained edge devices remains a significant challenge due to their high memory footprint and substantial compute requirements. In this paper, we propose a reparameterized transformer framework that integrates High-Rank Factorization (HRF) during training, layer merging at inference, and dynamic, load-balanced distributed inference across multiple devices. To further reduce resource usage, our framework supports mixed-precision quantization down to 4-bit, enabling flexible accuracy–latency–energy trade-offs. Experimental evaluations on the ESC-50 environmental sound dataset demonstrate that our method matches or exceeds the performance of larger baseline models while using 20–30% fewer parameters, achieving up to 48% latency reduction in …

Measurement-Aware Zero-Phase Iterative Learning Control For Robust Regulation Of Nonideal Boost Converters In Electric Vehicle Fast Charging, Aytaç Altan, Mohammed S. Alzaidi, Cağfer Yanarateş

Turkish Journal of Electrical Engineering and Computer Sciences

Integrating battery energy storage with DC-DC boost converters for electric vehicle fast charging exposes the regulator to ageing-induced parameter drift, periodic load pulses, and, critically, the nonidealities in the output-voltage sensing chain. This paper proposes a measurement-aware, zero-phase iterative learning control scheme for robust output-voltage regulation of a nonideal boost converter whose parameters are matched to those of a commercial Texas Instruments TPS6102x battery regulator. The controller combines an inner proportional-integral stabilizing loop with an outer zero-phase learning law that updates a feedforward correction based on the sensor-captured output trajectory; a forward-backward robustness filter suppresses the amplification of measurement noise …

Revealing Cryptic Lineage Diversity In The Persian Gulf And Oman Sea Groupers (Perciformes: Epinephelidae): Phylogenetic And Species Delimitation Insights, Ehsan Damadi, Faezeh Yazdani Moghaddam, Masoumeh Gholipour Cheshm Gilak, Mehdi Ghanbarifardi

Turkish Journal of Zoology

Groupers (Epinephelidae) are a taxon of great commercial interest due to their large body size and high market value, and are also an important ecological species for biodiversity conservation in coral reef ecosystems. Despite their importance, phenotypic convergence among species generally leads to incorrect taxonomic identification, an issue enhanced by molecular studies revealing the presence of a high cryptic diversity and complicating conventional systematic frameworks. Herein, grouper species diversity in the ecologically heterogeneous Persian Gulf and Oman Sea was investigated to resolve taxonomic ambiguities and assess patterns of cryptic diversity. Mitochondrial COI gene sequencing was used in conjunction with integrative …

A Binary Multiobjective Hippopotamus Optimization Algorithm For Feature Selection In Phishing Website Detection, Fatima Belmessaoud, Sofiane Maza, Djaafar Zouache

Turkish Journal of Electrical Engineering and Computer Sciences

Phishing website detection remains a major challenge in cybersecurity as attackers continuously develop new techniques to deceive users. Identifying the most informative features from large datasets is essential to improve classification accuracy while reducing computational complexity. Feature selection is therefore widely addressed using metaheuristic optimization techniques due to their flexibility and global search capability. In this study, we propose a Binary Multiobjective Hippopotamus Optimization Algorithm (B-MOHOA) for feature selection in phishing website detection. The proposed method simultaneously optimizes two conflicting objectives: maximizing classification accuracy and minimizing the number of selected features. Unlike many existing studies that mainly focus on transfer …

Range–Angle-Dependent Oam Beamforming With A Concentric Helical Circular Fda, Uğur Yeşi̇lyurt

Turkish Journal of Electrical Engineering and Computer Sciences

Secure and spatially selective wireless transmission requires orbital angular momentum (OAM) beams that are confined to a specific range and angle, rather than propagating indefinitely along the beam axis. In this paper, a concentric helical circular frequency diverse array (CHCFDA) is proposed to generate range–angle-dependent OAM beams without requiring external phase shifters. The helical element positioning inherently provides the necessary interelement phase distribution through physical step height, while logarithmically increasing frequency offsets are applied across concentric rings—and optionally across individual elements—to eliminate range periodicity and achieve a single, well-focused OAM beam exclusively at the target location. Both linear and logarithmic …

Predictors Of Psychological Strain In College Students In The Context Of The Covid-19 Pandemic, Randy M. Ludwig

Journal of Social, Behavioral, and Health Sciences

The coronavirus disease 2019 (COVID-19) pandemic exacerbated the traditional challenges of being a college student. This study examined the factors associated with the mental health difficulties many college students faced during the pandemic. Factor analysis was used to uncover a latent variable called psychological strain, which was composed of mental instability, mental health strain, sadness, anxiety, and unhappiness. An exploratory path model was created to determine which factors most closely related to psychological strain. Of the 14 factors considered, 11 were significant predictors. Overall, the most important risk factor was found to be social isolation (total effects = .437), while …

Confirmatory Factor Analysis And Measurement Invariance Of The Sexual Orientation Concealment Scale Among Nonbinary Lgbtq+ Adults, Peter D. Goldie, Michael T. Bixter, Suzanne Mclaren

Department of Psychology Faculty Scholarship and Creative Works

Sexual orientation concealment is a prevalent minority stressor among LGBTQ+ people (including nonbinary people) and it is associated with a series of adverse mental health outcomes. The Sexual Orientation Concealment Scale (SOCS) is a widely used brief measure assessing sexual orientation concealment. Although the SOCS has been used with diverse cisgender populations, its validity for nonbinary people, including those of varied racial/ethnic backgrounds and sexual orientations, remains unknown. Based on data from an international sample of 340 nonbinary LGBTQ+ individuals, the present study reports the findings of a confirmatory factor analysis to assess the one-factor structure and validity of the …
