This paper considers the problem of controlling a team of camera-equipped robots to ensure a mobile human target is observed by at least one robot at all times. We focus on determining team trajectories over a fixed time horizon such that the human target is in at least one robot's field of view even while the line of sight to the target can be obstructed by obstacles. Our approach to solving this problem lies in using a particle-based Belief Propagation method to estimate the most likely poses for each robot over time such that the visual tracking requirement is satisfied. Our approach is validated in simulation studies and an experimental trial where a human target must be tracked by a pair of miniature autonomous robot blimps.

Accurately estimating spatio-temporal gait parameters such as stride height, stride length, stance time, swing time, and stride speed, is crucial for sports medicine and preventive healthcare. Therefore, this paper proposes a novel ensemble method, NEST (standing for Novel Ensemble method for Spatio-Temporal gait parameters measurement), for the multi-task measurement of the aforementioned five spatio-temporal gait parameters. NEST consists of a K-Nearest Neighbor (KNN) regressor branch and a deep learning branch. The KNN regressor branch provides initial estimates, allowing other neural networks to learn to reduce the residual between these estimates and the ground truths. This helps NEST rapidly identify a good optimization direction during the early stage of fine-tuning and expedite convergence speed. The deep learning branch facilitates information sharing among multiple task-specific representations through fully-connected layers, effectively preserving the interdependencies among gait parameters. Several experiments are conducted to evaluate the performance of NEST and other prior methods. Compared to prior handcrafted-statistics-based methods, NEST demonstrates over 65.1% improvement in RMSE (Root-Mean-Square Error) when predicting spatial parameters. NEST also outperforms prior deep-learning-based methods not only in measurement accuracy but also in reducing training time by more than 14.6%. © 2024, The Authors. All rights reserved.

The purpose of the current work is to provide the numerical solutions of the fractional mathematical system of the susceptible, infected and quarantine (SIQ) system based on the lockdown effects of the coronavirus disease. These investigations provide more accurateness by using the fractional SIQ system. The investigations based on the nonlinear, integer and mathematical form of the SIQ model together with the effects of lockdown are also presented in this work. The impact of the lockdown is classified into the susceptible/infection/quarantine categories, which is based on the system of differential models. The fractional study is provided to find the accurate as well as realistic solutions of the SIQ model using the artificial intelligence (AI) performances along with the scale conjugate gradient (SCG) design, i.e., AI-SCG. The fractional-order derivatives have been used to solve three different cases of the nonlinear SIQ differential model. The statics to perform the numerical results of the fractional SIQ dynamical system are 7% for validation, 82% for training and 11% for testing. To observe the exactness of the AI-SCG procedure, the comparison of the numerical attained performances of the results is presented with the reference Adam solutions. For the validation, authentication, aptitude, consistency and validity of the AI-SCG solver, the computing numerical results have been provided based on the error histograms, state transition measures, correlation/regression values and mean square error. © 2022, The Author(s), under exclusive licence to EDP Sciences, Springer-Verlag GmbH Germany, part of Springer Nature.

In this work, based on the framework of the ongoing OASEES EU-funded project, we have discussed the concept of a Decentralized Autonomous Organization (DAO) that operates on a blockchain and governed by smart contracts. Then we have focused upon the description of a specific use case related to high mast inspection of telecommunications infrastructures. OASEES intends to integrate the DAO paradigm for the self-organized operation of a drone swarm, which will rely on the tight consolidation of the networking (e.g., 5G/B5G) and edge acceleration technologies (e.g., Spiking Neural Networks). We have introduced this use case and also discussed current state-of-the-art together with existing limitations. In addition, we have identified intended scenarios of use and proposed specific requirements for conformance to the corresponding project architecture. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Measurement: Sensors 2023年 26卷

作者： Rosayyan, Prakash Paul, Jasmine Subramaniam, Senthilkumar Ganesan, Saravana Ilango Intelligent Transportation and Networking Section of C-DAC Thiruvananthapuram Thiruvananthapuram695033 India Department of Computer Science and Engineering St. Thomas Institute for Science and Technology Thiruvananthapuram695584 India Department of Electrical and Electronics Engineering National Institute of Technology Tiruchirappalli620015 India

Smart city mission is a concept which improves economic growth and quality of life of people by using Information and Communication technology (ICT). Smart cities collect data from various Internet of Things (IoT) sensors and manage the resources and provide service to the public. Emergency Vehicle Priority/Pre-emption (EVP) is one of the major IoT components in smart cities which saves many lives by giving right of way green signal to the Emergency Vehicles (EVs) such as ambulances and fire engines. The existing EVP system gives green signal to the EVs immediate by stopping the conflicting movements. The sudden stoppage of normal traffic as well as the sequence change generates confusion to the road users and drivers. This needs an optimal control strategy which gives green signal to EVs as well as it should not affect the normal traffic flow. This paper proposes an optimal control strategy for EVP using edge computing and IoT sensor for smart cities. The experiment was conducted using a GPS based IoT sensor which keeps on sending the Location Information (LI) to the edge server. The edge server computes the optimum timings based on the proposed control strategy algorithm and clears the emergency vehicles. Waiting time of other road vehicles before and after implementing the system have been studied at a traffic junction at Thiruvananthapuram, India. The comparison result shows that the average waiting time of vehicles on the other road is reduced by 73.23% in the proposed system when compared with the existing system. Since, edge computing has been deployed the latency in communication has been reduced less than 100 ms. So, the proposed solution reduces the waiting time of other road vehicles and reduces the latency in communication simultaneously. © 2023

This study presents an astrophysics-inspired transit search optimization (TSO) algorithm based on exoplanet search divided into five phases: galaxy phase, star phase, transit phase, neighbor phase and exploitation phase for effective parameter estimation of fractional Hammerstein control autoregressive (Fr-HCAR) systems. Various physical phenomena and real processes can be modeled with Fr-HCAR systems and estimating the Fr-HCAR parameters becomes a vital task. The mean-square error (MSE)-based criterion function is developed, and efficacy of the TSO for Fr-HCAR identification is deeply analyzed for different fractional orders, disturbance levels and degrees of freedom. The TSO remained accurate, convergent, robust and stable for all variations in Fr-HCAR but the accuracy level degrades a little bit for high disturbance and increased degrees of freedom. The reliability and trustworthiness of the TSO for Fr-HCAR identification are endorsed through statistical analyses conducted on sufficient autonomous executions of the scheme. © 2025 World Scientific Publishing Company.
