A novel droop coefficient to realize rapid SOC balance for distributed energy storage systems

In the realm of isolated direct-current microgrids with varying distributed energy storage unit capacities, a new energy equalization strategy is proposed. This method involves an innovative approach that integrates an improved state-of-charge equalization control integrated with a sigmoid function to adaptively adjust the droop coefficient, aiming to accelerate the state-of-charge equalization rate. Furthermore, a virtual voltage drop equalization control is designed to dynamically adjust the output current of each distributed energy storage unit through a simple proportional–integral controller. This eliminates the influence of line impedance on accurate current distribution, improving overall accuracy. Additionally, a dynamic consistency algorithm is employed to gather average information about the distributed energy storage system, reducing communication line pressure as local nodes only exchange information with neighboring nodes. Integrating the aforementioned modules, the strategy proposed in this paper achieves rapid state-of-charge equalization, precise distribution of output current, and stable maintenance of the bus voltage. Finally, rigorous analysis of experimental results under various operating conditions verifies the feasibility and effectiveness of this control strategy by using the RT-LAB.

Theorizing the spatiality of ICT-mediated transnational repression: Evidence from China’s repression of Uyghurs in Turkiye

Recent years have witnessed burgeoning scholarly interest in how authoritarian states use transnational repression to intimidate and punish their citizens abroad. Our freshly collected surveys and in-depth interviews with members of the Uyghur diaspora in Turkiye reveal that China’s transnational repression of the Uyghur diaspora goes beyond preventing political mobilization. With the use of Internet Communication Technologies (ICTs), China employs widespread repression against ordinary Uyghurs by cutting off their communication lines with their homeland and through the Chinese police constantly harassing and threatening them, mostly through social media applications. Despite the growing body of literature on transnational repression, the spatial dimension of ICT-mediated transnational repression remains relatively undertheorized. Building on the literature of critical geopolitics, digital geographies, and Foucault’s concept of panopticon this study theorizes that China’s ICT-based practices beyond its borders have led to the configuration of “a transnational social space of insecurity,” which constitutes an idiosyncratic form of repression and spatiality by affecting diaspora Uyghurs’ everyday practices through the pervasive use of tech-based apparatuses and mechanisms. This idiosyncratic space constitutes and is constituted by “disciplinary” and “automated” subjects pushed toward constant self-surveillance and self-discipline. While China has physically turned East Turkestan into an open prison through political education camps, forced labor in production chains, ubiquitous installation of CCTV cameras, and frequent police control on phones and computers, ICTs enable China to transfuse its repressive system to the transnational domain by creating a parallel social space, which functions as its quasi-spatial extension.

Method for determining the effect of destabilizing factors of digital filters on the multicriteria synthesis of radio communications of aviation robotic devices

The purpose of the research is development of a method for determining the influence of destabilizing factors, such as the unevenness of the amplitude-frequency response (AFC) and the nonlinearity of the phase-frequency response (FFC), in non-recursive digital frequency selection filters on the target function of multicriteria structural-parametric synthesis of radio communications from the payload of aviation robotic devices.Methods. In conducting scientific research, probability theory, mathematical statistics, statistical radio engineering and computational mathematics were used. The study obtained mathematical expressions of the dependence of the probability of error per bit (BER) on the average signal-to-noise ratio when signals pass through symmetrical non-recursive digital filters with quadrature amplitude modulation with a positivity of no more than 4096, signal constellation irregularities of no more than 5, which are the basis for the energy balance of radio lines with aviation robotic devices. The expressions obtained are one of the "foundations" for the implementation of a multi-criteria synthesis of radio systems adaptive to a cognitively formed flight task. In this paper, all the results of the probability of reliability of the received data by means of communication are reflected for the case of rigid decision-making (Gray coding).Results. In the course of the conducted research: 1) a mathematical model of the structural-parametric synthesis of radio communications with aviation robotic devices is demonstrated, which is based on the criteria for minimizing: electronic computing resources with a given noise immunity; radiation outside the operating frequency band; peak factor signals; the effects of narrowband, broadband and structural interference in the radio channel at a given bandwidth; the use of structural and functional nodes specific to the existing information and communication environment; 2) the analytical dependence of the influence of the parameters of one of several structural and functional nodes - digital filters of frequency selection, on the criteria for the synthesis of communication means has been revealed. The paper considers the most common approximating functions - Kaiser, Tukey, Barlett-Khan, Chebyshev, and also shows the influence of the filter order on the equivalent of energy loss in information communication lines of aviation robotic devices.Conclusion. The scientific article presents a method for determining the effect of the uneven frequency response of a symmetrical non-recursive digital filter in devices for receiving and processing radio signals of multicriteria means of communication with the payload of aviation robotic devices. The proposed approach increases the reliability of determining the values of criteria for minimizing electronic computing resources for a given noise immunity, radiation outside the operating frequency band, as well as the use of structural and functional nodes characteristic of the existing information and communication environment.

A hybrid machine learning-based cyber-threat mitigation in energy and flexibility scheduling of interconnected local energy networks considering a negawatt demand response portfolio

The interconnection of local energy networks (LENs) enables efficient exchange of energy and flexibility among them, fostering the integration of distributed energy resources and demand-side management strategies. Thus, the interconnected local energy systems (ILEN) structure is a viable approach to electrical distribution systems’ operation and management. However, implementing distributed energy management structures such as ILEN entails a great amount of information transactions. Therefore, these structures are more vulnerable to cyber threats. Thus, the newly developed efficient and secure power systems’ operation methods should take digitalization-related security risks into account. As a result, this paper is focused on the development of a secure operation method, equipped with a hybrid algorithm to mitigate cyber threats in the context of ILEN. In this regard, this research proposes a novel hybrid XGBoost-based cyber threat mitigation (HXGBTM) method to cope with the vulnerabilities of the physical and information layers of the cyber-infrastructure. The proposed cyber threat mitigation method is built upon the classification and regression capabilities of the XGBoost ensemble of decision trees to identify and mitigate anomalies in the electrical consumption data. Therefore, in the first step, the ILEN’s multi-objective energy and flexibility scheduling problem considering demand response portfolio i.e., MOEFSDRPILENis developed that encompasses a bi-level optimization problem, in which the operator of the ILEN optimizes energy and flexibility trading in the upper level. While in the lower level, each LEN operator minimizes scheduling costs along with maximizing the local flexibility as well as providing a demand response portfolio as a negawatt resource. Here, the flexibility index, which is later maximized using the second objective function, is considered as the proportion between "the available ramping capacity" and "required ramping capacity". In this paper, direct load control, and interruptible/curtailable demand response comprehensive models are implemented as candidate programs for the suggested portfolio. Furthermore, a hybrid cyber threat is modeled considering the communication line intrinsic vulnerability, as a result of natural causes, wear, and aging of the infrastructure etc., as well as false data injection (FDI) attacks that target each LEN’s electrical consumption database. Finally, the proposed HXGBTM is employed to mitigate the above-mentioned cyber-vulnerabilities and achieve near real-world conditions.

Analysis and Prediction of Path Loss for Mobile Communication Lines in Nasarawa State Using Propagation Models

The design of future-generation mobile communication systems depends critically on the path loss prediction methods and their suitability to various signal propagation regions. Even though 5G has been launched in Nigeria, its deployment still faces significant challenges especially in the suburban, and non-urban regions which still depends on 4G. Many operators are still in the process of upgrading their existing 4G networks to support network coverage and higher speed data throughput. Due to the unique mix of Nasarawa State with diverse terrains, in this study, path loss prediction for the key telecommunication networks in Nasarawa State was carried out using Signal Strength Info App. Data was collected for a period of eight weeks (August, 2nd to September, 4th 2023) focusing on 4G LTE networks operating within the 1800 MHz frequency band. Analysis of path loss using empirical models such as Hata, Egli, and COST-231 Hata models were compared with the measured path loss in different terrains of urban, sub-urban, and non-urban environments. The Root Mean Square Error (RMSE) analysis was carried out between empirical and measured path losses. Results shows that, the order of mean predicted path loss at 5km was free space model (BN>CN>DN.AN), Hata model (DN>BN>CN>AN), Cos-231 Hata model (CN>AN>BN>DN), and Egli model (AN>BN>DN>CN). Hate model predicted the highest path loss values while Egli model predicted the lowest values. Overall, Egli model is found to be the most reliable and suitable path loss prediction model for entire Nasarawa State with RMSE value 5.99dBm, 2.90dBm and 3.14dBm for Nasarawa, Keffi and Akwanga LGA respectively. However, Cost-231 Hata model with RMSE value of 5.71dBm is suitable for path loss prediction in Karu due to its irregular terrain. The findings of this study are significant for practical applications in network planning, base station coverage, frequency allocation, and signal strength management, ensuring optimal mobile network performance across various terrains.

Low-Cost Purpose-Built Ultra-Low-Field NMR Spectrometer.

Low-field NMR has emerged as a new analytical technique for the investigation of molecular structure and dynamics. Here, we introduce a highly integrated ultralow-frequency NMR spectrometer designed for the purpose of ultralow-field NMR polarimetry of hyperpolarized contrast media. The device measures 10 cm × 10 cm × 2.0 cm and weighs only 370 g. The spectrometer's aluminum enclosure contains all components, including an RF amplifier. The device has four ports for connecting to a high-impedance RF transmit-receive coil, a trigger input, a USB port for connectivity to a PC computer, and an auxiliary RS-485/24VDC port for system integration with other devices. The NMR spectrometer is configured for a pulse-wait-acquire-recover pulse sequence, and key sequence parameters are readily controlled by a graphical user interface (GUI) of a Windows-based PC computer. The GUI also displays the time-domain and Fourier-transformed NMR signal and allows autosaving of NMR data as a CSV file. Alternatively, the RS485 communication line allows for operating the device with sequence parameter control and data processing directly on the spectrometer board in a fully automated and integrated manner. The NMR spectrometer, equipped with a 250 ksamples/s 17-bit analog-to-digital signal converter, can perform acquisition in the 1-125 kHz frequency range. The utility of the device is demonstrated for NMR polarimetry of hyperpolarized 129Xe gas and [1-13C]pyruvate contrast media (which was compared to the 13C polarimetry using a more established technology of benchtop 13C NMR spectroscopy, and yielded similar results), allowing reproducible quantification of polarization values and relaxation dynamics. The cost of the device components is only ∼$200, offering a low-cost integrated NMR spectrometer that can be deployed as a plug-and-play device for a wide range of applications in hyperpolarized contrast media production─and beyond.

МОБІЛЬНІ ЦИФРОВІ ТРОПОСФЕРНІ СТАНЦІЇ З КОМБІНУВАННЯМ ПРОСТОРОВО-РОЗНЕСЕНИХ СИГНАЛІВ

The article examines mobile digital troposcatter stations and mobile combined digital radio engineering stations, which will include systems of spatially diversity signals. This is a well-known method of increasing the stability of communication and obtaining the necessary quality indicators when transmitting signals through multipath channels. The methods of receiving spatially diversity signals can be classified as diversity reception with combining signals by microwave frequency, intermediate frequency and the main working frequency band. Methods of combining spatially diversity signals: automatic selection; linear assembly; optimal assembly. The article examines in detail the signal composition scheme in the linear path before the demodulator and after the demodulator. The results of the research showed that the best opportunities are in linear assembly. At the same time, it was noted that autophasing methods play an important role: automatic control of the phases of heterodyne microwave signals and automatic phasing of composite signals at an intermediate frequency. With optimal composition, theoretically the greatest gain in terms of signal – to – noise ratio is obtained. However, the linear combination compared to the optimal gives a lower signal-to-noise ratio at the output of the combiner by only 1 dB. Therefore, for nodal and high-speed mobile digital troposcatter stations, the use of linear combination as a method of combining diversity signals is recommended. The article analyzes several structural schemes of the receiving path for spatially diversity signals with intermediate frequency combination in mobile digital troposcatter stations. Note that reception with spatially diversity of antennas continues to be the main means of improving communication stability on troposcatter communication lines during the transmission of digital signals. The article discusses the methods of receiving and combining spatially diversity signals in which there are no interruptions in communication due to switching. Linear combination are widely used in modern mobile digital troposcatter and combined radio engineering systems, the components of which is the troposcatter component.

A distributed coordinated control strategy for isolated AC microgrids based on consensus algorithm considering communication delay

AbstractIn the multi‐paralleled converter microgrid system, the traditional hierarchical control strategy can eliminate the bus voltage amplitude and frequency deviation from the rated value. However, isolated AC microgrids may face extreme scenarios such as communication delays and interruptions in data transmission due to the use of low‐bandwidth communication (LBC) lines. Additionally, the inconsistent line impedance of each distributed generation (DG) unit may result in the inaccurate division of reactive power in multi‐paralleled converter systems, thus affecting system stability. To address these issues, this paper presents a distributed coordinated control strategy for isolated AC microgrids based on the consensus algorithm. The proposed strategy first replaces LBC lines with a filter to alleviate the effects of communication delays. A small‐signal model is established in its state space, and stability of the microgrid system under the proposed control strategy is verified through eigenvalue analysis. Furthermore, based on the above theoretical analysis, a consensus algorithm is introduced, and a distributed control strategy for isolated AC microgrids based on the consensus algorithm is proposed to solve the issue of inaccurate equalization of the system's reactive power. Finally, factors that influence the dynamic convergence performance of the consensus algorithm are analyzed through simulation in PLECS software. Also, the maximum tolerable communication delays of the microgrid system under different communication topologies are also compared, and the system's robustness is evaluated under the condition of sudden communication interruption in a DG unit and sudden weather variation. These analyses confirmed the robustness of the proposed strategy against communication delays, output power fluctuation, and communication interruptions.

Прогнозирование помех электростатического разряда в электронном устройстве с использованием искусственной нейронной сети

Electrostatic discharge is a dangerous source of natural electromagnetic interference to the operation of modern electronic devices. Although measures have been taken to reduce and remove electrostatic discharge from the operating area of electronic devices, the absence of such discharge cannot be guaranteed. Therefore, when designing modern electronic devices, it is necessary to take into account the possibility of such electrostatic discharges in advance and take protective measures. The article proposes a method for predicting the amplitude of interference in the communication line of an electronic device when exposed to an electrostatic discharge on its metal case. The technique is based on the use of an artificial neural network. The technique includes the analysis of significant input parameters that affect the amount of interference in an electronic device; development of an experimental stand for measuring interference; choosing the structure and parameters of a neural network for predicting interference; choosing a training method for an artificial neural network; choosing a metric for assessing the quality of training; normalization of training data; training an artificial neural network using experimental noise data; predicting the amplitude of interference in the communication line of an electronic device when exposed to an electrostatic discharge on its body; where necessary, selecting and implementing electrostatic discharge protection measures. Examples of training an artificial neural network based on experimental data are given. The training was carried out for 572 epochs. For the training and testing sets, the discrepancy between the predicted data and the average measured noise values was 3.61% and 3.95%, respectively. Examples are given of predicting the amplitude of interference when exposed to electrostatic discharge. The results obtained indicate the possibility of practical use of an artificial neural network to solve problems of electromagnetic interference analysis.

Cascaded H-bridge power carrier communication method based on harmonic injection

Abstract Scaded H-bridge inverter systems are widely used, but there are complex communication problems between multiple module communications. In this paper, a power carrier communication method injecting the third harmonic is proposed for a single-phase cascaded H-bridge system. The third harmonic is superimposed on the SPWM sinusoidal waveform as a modulating signal and demodulated from the acquired current signals by means of DQ conversion. The baseband input signals are directly observed from the Id and Iq signals. There is no need to add additional communication lines. The method is simple and reduces costs.

The Epigraphic Testimonies from Timacum Maius (Eastern Moesia Superior): The Important Clues for the Character and Organization of Naissus Region

For more than ten years in a row, archaeologists of the Institute for Balkan Studies of SASA of the Serbian Academy of Sciences and Arts, in cooperation with the Ausonius Institute from Bordeaux, have been conducting archaeological research on the Roman and Byzantine settlement located in the area of the village of Niševac near Svrljig, in the Svrljiški Timok River valley. It was the first station on the Roman itinerary road between Naissus (Niš) and Trajan's colony of Ratiaria on the Danube (Archar in northwestern Bulgaria). In addition to significant architectural remains and various archaeological findings, some inscriptions in Latin and Greek are also known from this area. This bilingualism of the texts indicates the very location of Timacum Maius, which was located on a vital communication line and a linguistic and administrative interprovincial barrier. Although chronologically different, the epigraphic findings I report raise broader scientific questions about the significance of this ancient settlement and its population, especially in the early military history of the Naissus region.

TRENDS OF THE MICROWAVE PHOTONIC RADARS

Today, the world's leading countries are intensively working on the development of new generation radars - microwave photonic radars. Microwave photonic radars make it possible to significantly reduce the mass and size characteristics of radar stations, to increase the information capability and range of target detection due to the reduction of losses in long communication lines when using optical fiber, to ensure high immunity due to the significantly lower sensitivity of optical-electronic equipment and fiber-optic lines of communication connection to external electromagnetic influences. Microwave photonics provides wide bandwidth, flat response, low loss transmission, multi-dimensional multiplexing, ultra-fast analog signal processing and immunity to electromagnetic interference. Radar implementation in the optical domain can provide better resolution, coverage, and speed performance, which would be difficult to implement with traditional electronics. The review article examines the state of development and system architectures of such photonic radars as optoelectronic hybrid radars, all-optical radars, multifunctional microwave photonic radar systems, distributed microwave photonic radars, software-defined radars, and cognitive radars. New technologies in this field and possible future directions of research are discussed. As an example, a broadband microwave photon radar reproduced on the basis of a microcircuit is considered. The broadband signal generator and receiver are built into the silicon crystal on the insulator. A high-precision distance measurement with a resolution of 2.7 cm and an error of less than 2.75 mm was obtained. Visualization of multiple targets with complex profiles has been implemented. But the performance of most integrated microwave photonic chips is not yet satisfactory for practical radar applications. Monolithic integration of key microwave photonic subsystems is also not mature enough for practical applications, so hybrid integration of devices fabricated on their optimal integration platforms is of practical interest. At present, indium phosphide, silicon nitride and silicon on insulator are the three leading platforms for photonic integration

Quantum Cryptography: Mathematical Foundations and Practical Applications for Secure Communication Protocols

Quantum cryptography is a new and exciting area that uses quantum physics to protect communication lines from being spied on or intercepted. Fundamental ideas in this field, like the uncertainty principle and the fact of quantum entanglement, are used to achieve levels of security that have never been seen before. Our in-depth study, "Quantum Cryptography: Mathematical Foundations and Practical Applications for Secure Communication Protocols," looks at both the math behind quantum cryptographic protocols and how they are used in the real world. Our study goes into great detail about the theories behind quantum cryptography. It explains ideas like quantum key distribution (QKD), quantum teleportation, and quantum secure direct communication (QSDC). One of the main ideas behind quantum cryptography is the idea of qubits, which are like regular bits but in quantum mechanics. They can be in more than one state at the same time because of superposition. Quantum cryptographic methods use this property to make sure communication is safe by putting data in quantum states and taking advantage of the fact that quantum measures are inherently unpredictable. The study we're doing looks at how to use quantum cryptography in typical everyday situations. We look at the problems that come up when you try to build infrastructure for quantum transmission, such as noise, decoherence, and scale. We make a plan for making strong and trustworthy quantum cryptographic systems by giving details about how experiments are set up and how technology is improving. Our study looks into how quantum cryptography could be used for things other than just keeping communications safe. We look into what it means for new technologies like quantum networks, quantum computing, and safe multi-party processing. We hope that by explaining the bigger effects of quantum cryptography, we can encourage more study and new ideas in this ground-breaking area.

Quaternionic generalization of telegraph equations

Using non-commutative spacetime quaternion algebra, we represent the generalization of one-dimensional and three-dimensional telegraph equations, which are widely applied to consider the propagation of an electromagnetic signal in communication lines, as well as to describe particle diffusion and heat transfer. It is shown that the system of telegraph equations can be represented in compact form as a single quaternion equation taking into account the spacetime properties of physical quantities. The distinctive features of the one-dimensional and three-dimensional telegraph equations are discussed.

Clinical practice guidelines for telesurgery 2022

Telesurgery is expected to improve medical access in areas with limited resources, facilitate the rapid dissemination of new surgical procedures, and advance surgical education. While previously hindered by communication delays and costs, recent advancements in information technology and the emergence of new surgical robots have created an environment conducive to societal implementation. In Japan, the legal framework established in 2019 allows for remote surgical support under the supervision of an actual surgeon. The Japan Surgical Society led a collaborative effort, involving various stakeholders, to conduct social verification experiments using telesurgery, resulting in the development of a Japanese version of the “Telesurgery Guidelines” in June 2022. These guidelines outline requirements for medical teams, communication environments, robotic systems, and security measures for communication lines, as well as responsibility allocation, cost burden, and the handling of adverse events during telesurgery. In addition, they address telementoring and full telesurgery. The guidelines are expected to be revised as needed, based on the utilization of telesurgery, advancements in surgical robots, and improvements in information technology.

UDC 376.07:005.95(477-072)“364” FEATURES OF MANAGEMENT OF SPECIAL AND INCLUSIVE EDUCATION INSTITUTIONS IN THE FRONTLINE REGION

The article examines the current challenges faced by the heads of special and inclusive educational institutions in the context of ongoing hostilities in Ukraine. The aim of the article is to analyze and highlight these challenges, with an emphasis on the need to modernize management approaches in response to the growing influence of inclusive processes. The authors emphasize the critical importance of forming a new generation of educational leaders who have the necessary competencies to manage innovative educational institutions that implement inclusive approaches. This includes the recognition of universal values, ensuring the humane treatment of people with disabilities, as well as addressing the issues of their socialization and adaptation in society as a whole. Strategic directions of inclusive education require leaders who are not only aware, but also actively engaged in creating and maintaining environments where both healthy pupils and students with special educational needs can study together in specialized institutions. The article emphasizes the need for these leaders to be well aware of the latest trends in the development of special and inclusive education and to effectively manage the complex dynamics that arise in the frontline regions. In these regions, the challenges are particularly acute, with security, infrastructure preservation, staffing and adequate funding coming to the fore. The constant threat to life due to hostilities poses significant risks to the physical and psychological well-being of students and staff. The destruction of infrastructure, including educational facilities, exacerbates the difficulties of maintaining a stable learning environment. Communication problems, whether due to damaged networks or broken communication lines, make it even more difficult to manage these institutions. Staff shortages, often caused by the relocation of staff or the inability to attract qualified specialists to dangerous areas, add another layer of complexity to the management task. The article also highlights the problem of professional burnout, which is exacerbated by stressful working conditions in the conflict zone. In addition, frequent interruptions in the educational process, whether due to evacuations, damage to facilities, or other war-related disruptions, significantly complicate the ability of these institutions to fulfill their educational mission. The article concludes by emphasizing the need for rapid adaptation and innovative solutions on the part of education managers to effectively address these challenges, ensuring that inclusive education can continue to progress even in the most adverse conditions.

Моделирование помех в электронном устройстве при воздействии импульсного магнитного поля с использованием искусственной нейронной сети

Modern electronic means are quite sensitive to electromagnetic interference. At the same time, they must function reliably in the existing electromagnetic environment. Lightning discharges and industrial sources make a significant contribution to the formation of the electromagnetic environment around electronic equipment. In this case, pulsed magnetic fields with microsecond parameters most often arise. The most rational approach to ensuring electromagnetic compatibility of electronic means is the most complete accounting and protection from possible phenomena at the design stage. Different methods for modeling the consequences of exposure to electromagnetic interference have their own advantages and disadvantages. To develop a technique and modeling interference in electronic means based on an artificial neural network using the example of the influence of a pulsed magnetic field a the purpose of this work. A practical technique for calculation the magnitude of interference in electronic means using an artificial neural network the paper proposes. All stages of the technique are described: analysis of the main input parameters affecting the amount of interference in the electronic means; the use of a special experimental stand for measuring interference depending on significant input parameters; choosing the structure and parameters of an artificial neural network to modeling interference; choosing a training method for an artificial neural network; choosing a criterion for assessing the quality of training when solving a regression problem; normalization of training data; training an artificial neural network using measured data; modeling the amount of interference in the communication line of an electronic means when exposed to a pulsed magnetic field; assessment of consequences and selection of methods of protection against interference. As an example, we consider the problem of modeling the amount of interference in a communication line inside an electronic means when exposed to a pulsed magnetic field. The magnetic field has parameters recommended by the requirements of the regulatory document on electromagnetic compatibility of devices. In the problem under consideration, an acceptable discrepancy in results is achieved with an acceptable number of neural network training epochs.

Shared Governance Through Bylaws: Transformation Within a College of Nursing.

Enhancing faculty voice and promoting shared governance within academia has long been called for but has not been well-reported. A college of nursing in the midwestern United States identified shortcomings in its organizational structure including lack of faculty voice, communication barriers, lack of faculty participation in decision making, and academic programs operating independently. A workgroup was formed to transform the bylaws to promote shared governance, including faculty voice, equality, and engagement. The bylaws were revised and presented to faculty for discussion, further revisions, and vote. The revised bylaws were approved and implemented in August 2021. Through transformation of the bylaws, the college's 12-committee structure was reconceptualized to five standing committees and 13 subcommittees. Clear communication lines and cross-committee collaboration was established to break down the former academic program silos. Faculty with primary teaching assignments are equally represented throughout the structure with voice, vote, and responsibility. [J Nurs Educ. 2024;63(5):277-281.].
