This research focuses on developing an Intrusion Detection System (IDS) for Internet of Medical Things (IoMT) applications, utilizing the CICIoMT-2024 dataset. It approaches the problem as a classification challenge, classifying traffic as either one of eighteen types of attacks or benign. The study analyzes the effectiveness of three boosting algorithms - XGBoost, AdaBoost, and CatBoost - in determining their accuracy for identifying various types of attack and benign traffic. The experimental results reveal that the XGBoost classifier achieves an accuracy of 95.01%, AdaBoost records an accuracy of 92.89%, and CatBoost attains an accuracy of 88.37%. Additionally, eXplainable Artificial Intelligence (XAI) is employed to enhance the interpretability of the machine learning models. © 2024 IEEE.

KUbeSat is an organization that has been established at the University of Kansas to respond to NASA’s CubeSat Launch Initiative (CSLI). The organization gives students the opportunity to engage in the satellite development process including designing and building a ground station. This paper discusses the transition from using a modem and transceiver for communication with the satellite to using a signal-defined radio (SDR) as the primary method of communication. Plans for future expansions are also discussed in the form of research for a ground station antenna and cube satellite transceiver in the S-band frequency range. © 2023 International Foundation for Telemetering.

Monitoring soil pH is important for optimizing plant biomass production, understanding nutrient cycling, predicting and mitigating greenhouse gas emissions, and improving soil health. Soil pH can vary significantly over time and space, and high spatiotemporal resolution data are needed to enable informed land management decisions. A potential method to address this need is to use large numbers of easily distributed pH sensor systems which can be placed at high density in soils. An approach for fabricating such sensors is described here using a voltammetric screen-printed pH sensor with a working electrode that incorporates Alizarin (a pH-sensitive dye) throughout its bulk. The use of a Nafion membrane on top of the working electrode and a salt membrane over the reference electrode provides near-Nernstian sensitivity and enhanced device stability in buffered media, soil, and hydroponic fluid. Critically, these devices can function effectively in a novel 2-electrode (working and reference) configuration with a sensitivity of 56.38 mV/pH and a resolution of 0.28 pH (n=3), enabling the use of simple, low-cost readout electronics for evaluating the sensor state. These results show that a printed pH sensor paired with affordable electronics can be used to monitor the pH of unbuffered media, providing a potential path to high-spatial density real-time measurement of pH in soils and hydroponics. © 2001-2012 IEEE.

Modern information technology is driving the rapid development of the information and automation industry through the combination of computer technology, communication technology, and control technology. Inspired by nature's cluster movement, such as birds, people proposed the concept of Multi-Agent Systems (MASs). This paper deals with the formation control problem for a class of heterogeneous multi-agent systems with time-delays. First, the formation control of heterogeneous multi-agent systems with communication delay in fixed and switching topologies is investigated. A heterogeneous multi-agent system model with input delay and communication delay is established. Furthermore, based on this model, the formation control protocol is designed and the stability of the proposed control protocol in fixed and switched topologies is analyzed. The first- and second-order multi-agent control system was formulated for both fixed and switched topology, respectively. Then, using the new LMI toolbox, the feasibility of the parameters is obtained and the example is created by MATLAB. The simulation results show that the proposed formation control protocol with delay in this paper can make the systems converge to the expected value under fixed and switched hierarchies. © 2013 IEEE.

For the minority of people who are speech and hearing impaired, communication is essential for self-expression. Despite the availability of numerous assistance, such as visual aids or interpreters, these approaches can be costly or time-consuming. Deaf and dumb people mostly utilize sign language to communicate with one other and within their own community. Since they are mute, they communicate with hand gestures in this language. "Sign language recognition" (SLR) is a process of identifying & learning hand motions, with the goal of producing text for each associated gesture. These hand movements have been trained and detected using a multi-headed "convolutional neural network" (CNN) model using the well-known sign language MNIST dataset from Kaggle. The algorithm achieved an 80–90% success rate in identifying the signs based on the provided motions. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

With the rapid development of digital and intelligent information systems, display of radar situation interface has become an important challenge in the field of human-computer interaction. We propose a method for the optimization of radar situation interface from error-cognition through the mapping of information characteristics. A mapping method of matrix description is adopted to analyze the association properties between error-cognition sets and design information sets. Based on the mapping relationship between the domain of error-cognition and the domain of design information, a cross-correlational analysis is carried out between error-cognition and design *** obtain the relationship matrix between the error-cognition of correlation between design information and the degree of importance among design information. Taking the task interface of a warfare navigation display as an example, error factors and the features of design information are extracted. Based on the results, we also propose an optimization design scheme for the radar situation interface.

KUbeSat-1 is a satellite in final development at the University of Kansas, planned to launch into a 550 km sun-synchronous orbit. Throughout the mission's development, data collection and management systems were created that handle data from the modules and experiments onboard using freeRTOS on a STM32F777 microcontroller. Health and operational data is collected from the modules, then staged on disk, and downlinked when prompted. Data from experiments is stored on a Raspberry Pi and transmitted to the on-board computer. The data is transmitted when the satellite overflies the ground station. This paper covers the development and operations of this system. © 2023 International Foundation for Telemetering. All rights reserved.

In this paper, we present an automated workflow for shock detection and processing in high-speed flow simulations. Here we present an efficient approach to detect and process shocks including those computed on relatively coarse unstructured meshes. We develop and apply a robust set of steps to target problems with shock systems containing interactions between different shock components/segments. In particular, these steps include de-fragmentation to f ill-up holes or missing shock elements/cells, sorting/labeling to determine contiguous set of shock elements/cells, removal of noise or small sets, and identification of each distinct shock segment/component. The resulting information could be used for shock fitting, e.g., for creating highly anisotropic orthogonal/layered elements aligned with shocks, and/or quantitative analysis of complex shocks. A combination of manufactured data and numerical simulation data is used to demonstrate the performance of the current procedure. Overall, the novel procedure developed in this work is found to be efficient and robust. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.

In this paper, a collision-free target tracking control approach utilizing guided vector field guidance is proposed. In particular, a synthesized vector field is designed to direct the snake robot toward the target while simultaneously navigating around multiple obstacles. In addition, a saturated guidance law is designed to compute a reference angular velocity to prevent damage to the robot joints. A dynamics control law is designed based on a reduced-order structure-modified expansion state observer to compensate for external disturbances and realize the robust target tracking and tracing control of the snake robot. Simulation results show the effectiveness of the proposed guidance and control method. © 2024 IEEE.
