Decreasing system inertia in microgrids due to high penetration of inverter-based resources necessitates enhancing system stability with virtual inertia. Optimal placement of virtual inertia significantly impacts system frequency behavior, making it a crucial consideration in virtual inertia provision. While some studies have employed relatively comprehensive storage device models for optimal virtual inertia placement, they often overlook the cost of battery degradation. The cost of battery degradation should be considered in optimization problem with respect to the importance of battery lifetime. This paper formulates an optimal cost function integrating virtual inertia technology costs, including installation, operation, battery degradation, and replacement. Incorporating battery degradation costs enhances battery health within the grid and provides a more accurate cost estimate for virtual inertia provision. By addressing the non-linearity of optimal virtual inertia placement, previous studies used genetic algorithms to find optimal solutions. with linear optimization methods thereby reducing non-linearity. In this paper replaced genetic algorithms with linear optimization methods to simplify the process of determining the optimal placement of virtual inertia, thereby linearized model for optimal virtual inertia placement problem.

Ensuring the fuse remains intact during a fault is a key challenge in coordinating protection devices within distribution networks and microgrids. Coordinating protection becomes more complicated with the integration of distributed generations and different operating modes. To address the issue of undetected faults by the recloser in island mode, employing a pair of directional over-current relays on the lines could be a viable solution. Similarly, the fault current limiter is used to apply consistent settings for relay characteristics in various operating modes of the distribution network. In this paper, we want to optimize the value of fault current limiter and relays settings be set in such a way which the total operation time of the main and backup relays is minimized and the coordination between relay-relay and relay-fuse is maintained. To achieve this, genetic algorithm has been used to calculate the optimal value of relay settings and fault current limiter. The advantage of this design is avoiding mistakes in protection zones due to resistance or measurement errors. Moreover, eliminating the need for telecommunication system, and requiring single settings for relays compared to similar approaches is other remarkable advancement in this method.

Non-invasive pig weight prediction is crucial for efficient pork production and animal welfare monitoring. This study introduces a novel approach combining Segment Anything Model (SAM)-enhanced image preprocessing with deep learning techniques for accurate pig weight estimation using depth images. We compare traditional statistical methods with advanced deep learning models, focusing on minimizing preprocessing requirements and improving accuracy. Our custom image preprocessing pipeline, leveraging SAM for precise segmentation, enables efficient feature extraction and data cleaning. We evaluate various models, including Convolutional Neural Networks (CNNs), Multi-input CNNs, ResNets, and XceptionNet, against statistical methods such as linear regression, random forest, and support vector regression. Results demonstrate that deep learning models, particularly XceptionNet, significantly outperform statistical approaches. XceptionNet achieves a mean absolute error of 2.82 kg and a mean absolute percentage error of 7.42%, compared to the best statistical model (support vector regression) with 4.51 kg and 15.56%, respectively. This study highlights the potential of integrating state-of-the-art segmentation techniques like SAM with deep learning for enhanced accuracy in livestock monitoring, paving the way for real-time, non-invasive weight prediction systems in modern pig farming.

This paper addresses the role of uncertainty in spatial point-process models, such as those that might arise in modelling ship traffic. We consider a doubly stochastic Poisson point process where the intensity function is uncertain. To assess the role of uncertainty, we conduct a large set of numerical trials where we estimate a doubly stochastic Poisson point-process model from historical target data, and the evaluate the model by assessing the target detection performance of a set of sensors whose locations are selected using the model. Our work is motivated by seabed sensors that detect ship traffic, and we conduct numerical trials using historical ship traffic data near the mouth of the Chesapeake Bay, Virginia, USA, that was recorded by the Automated Identification System. © 2023 SPIE.

Against a backdrop of massive population growth, the supply of essential urban services, such as water and power, in developing countries is not growing at nearly the same pace. The critical aspects of this urban development are poorly understood. The main objective of this study was to identify and analyze the different forms of governance in the water and electricity sectors in developing countries based on the existing literature. The synthesis of several studies shows that there is not one mode of governance that fits every time and place. In most cases, municipal authority involves the private sector in water and electricity management. In many countries that have liberalized electricity generation, regulation of municipal utilities is being reformed through the introduction of incentive regulation models. Engaging the population through anti-corruption campaigns is an effective way to improve governance. Given the cost of expanding the conventional power grid, solar PV has proven to be a safe and sustainable way to power urban and peri-urban districts. However, success in promoting this energy source lies in the involvement of the national and/or provincial government through incentive measures. We conclude that the governance of water and electricity in developing countries is successful when the following criteria are applied: decentralization, liberalization, public–private partnerships and community involvement. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Over-the-air precision two-way time transfer and ranging (PTTR) uses the signals exchanged between two RF transceivers to estimate the range between them and the offset between their clocks. Our paper makes three significant contributions to the estimation and position, navigation, and timing literature. First, we introduce a propagation channel model characterized by its amplitude (attenuation), phase shift, and propagation delay. This three-parameter formulation is quite practical for modeling signal exchange over line-of-sight channels with arbitrary additive wide-sense stationary noise that also captures electronic effects. Second, we derive the Cramer-Rao Lower Bound (CRLB) for this three parameter channel model. We show that there is a canonical definition of phase shift for which the CRLB is a diagonal matrix. The derived CRLB depends on simple properties of the signal and noise power spectral density (PSD) related to whitened bandwidth and whitened center frequency as well as the signal to noise ratio. Third, we derive a maximum likelihood estimator (MLE) for the amplitude, phase shift, and delay given the reference waveform, received waveform samples, and noise PSD. A novel aspect of the derived MLE is that it is implemented entirely in the frequency domain, which makes the MLE more computationally efficient than a typical time-domain implementation. Using an example reference waveform, we show that the derived MLE achieves an empirical covariance close to the CRLB for sufficiently high signal to noise ratios. The estimation results of our paper are directly relevant to over-the-air PTTR applications operating in direct-path, line-of-sight propagation environments. The generality of the waveform and noise formulations allow our estimator and bounds to be applied to arbitrary PTTR ranging waveforms in colored interference environments. We present a system architecture utilizing this estimator that enables PTTR on existing wireless networks with no changes to

The integration of artificial intelligence in mechanical fault detection and diagnosis (FDD) helps to increase reliability, reduce costs, and improve the overall performance of mechanical systems in Industry 4.0 applications. Most interesting industrial applications nowadays come from dynamic environments where data are generated continuously over time and where the labeled data are scarce and expensive. Therefore, semi-supervised learning (SSL) can be particularly useful in FDD because faults may be rare or difficult to identify, and may not be fully represented in the labeled data. By using a combination of labeled and unlabeled data, SSL can help to identify these rare or difficult-to-detect faults, leading to more effective FDD. In this paper, graph-based SSL relying on label propagation is combined with conventional classification algorithms to detect potential failures in complex mechanical systems. Experimental results on realistic pneumatic and hydraulic systems from the related literature show that the proposed method can effectively enlarge the labeled datasets and interestingly identify different types of non-nominal conditions with higher accuracy compared to baseline methodologies. © 2023 IEEE.

Spin-torque diodes based on magnetic tunnel junctions (MTJs) are devices with a wide range of potential industrial and technological applications. The nanoscale size of MTJs allows to efficiently exploit phenomena such as voltage controlled magnetic anisotropy (VCMA) to manipulate the ferromagnetic state and excite resonant modes in the device. In this work, we predict a fractional parametric resonant response in passive spintronic diode excited simultaneously by spin-transfer torque and VCMA by means of micromagnetic simulations. This resonance mechanism can be used for frequency divider and compact demodulation schemes. © 2023 IEEE.
