Anti-virus software (AVS) tools are used to detect malware in a system. However, AVS are vulnerable to attacks. A malicious entity can exploit these vulnerabilities to subvert the AVS. Recently, hardware components such as hardware performance counters have been used for malware detection. In this article, we propose preempts malware by examining embedded processor traces (PREEMPT), a zero overhead, high-accuracy, low-latency technique to detect malware by repurposing embedded trace buffer (ETB), a debug hardware component available in most modern processors. The ETB is used for postsilicon validation and debug and allows us to control and monitor the internal activities of a chip, beyond what is provided by the input/output pins. PREEMPT combines these hardware-level observations with machine learning-based classifiers to preempt malware before it causes damage. The benefits of reusing ETB for malware detection include the increased robustness against attacks and no performance penalties. PREEMPT can detect malware on an OpenSPARC T1 core running Linux operating system with a F1-score of 96.6%.

The increase in renewable-energy-based generations, such as photovoltaic and wind turbines, inevitably leads to an increase in the number and capacity of inverters connected to the power system. This also increases the voltage on the inverter-connected and adjacent buses. By absorbing reactive power appropriately, it can suppress excessive voltage and increase the potential capacity of real power. Currently, most inverters connected to the power grid are set up in a way that does not involve adjusting the voltage at the point of connection. This means that the inverter controller's limiter settings have not significantly impacted the system's stability after a fault. This article examines the impact of reactive power absorption on grid-connected inverters' stability and limiter values' effects on stability. Additionally, to set the limiter values for a convenient inverter controller, the causes of instability are explained in a phasor diagram, and a method for setting the limiter values using this information is explained. The stability impact analysis and limiter value setting are carried out through accurate EMT model-based simulations. The infinite bus with the equivalent impedance is used for the stability analysis and limiter values setting, and the determined values are verified on the real power system. The simulation is conducted using the power system computer-aided design and electromagnetic transient including dc.

This paper proposes a new parameter adjustment law for robust PID control systems with disturbance attenuation performance for polytopic uncertain multiple-input multiple-output (MIMO) systems. In the proposed design approach, the problem of designing the parameter adjustment law for robust PID control systems is reduced to a design problem of static output feedback controllers for uncertain MIMO systems. In this paper, we show that the sufficient conditions for the existence of the proposed parameter adjustment law for the robust PID control system can be reduced to the solvability of linear matrix inequalities (LMIs). Finally, a simple numerical example is provided to demonstrate the effectiveness of the proposed robust PID control system. © 2024 ieee.

Tactile Internet based operations, e.g., telesurgery, rely on the human operator for end-to-end closed loop control to achieve accuracy. While feedback and control are subject to network latency and packet loss, critical operations such as pose correction, fiducial marking, tremor reduction, etc. are tasks that should be carried out automatically and thus dispensing with these feedback signals from traversing the network to the other end. We design two edge intelligence algorithms hosted at P4 programmable end switches placed 400 km apart. These algorithms locally compute and command corrective signals. We implement these algorithms entirely on data plane on Netronome Agilio SmartNICs. "pose correction" is placed at the edge switch connected to an industrial robot gripping a tool. The round trip between transmitting force sensor array readings to the edge switch and receiving correct tip coordinates at the robot is shown to be less than 100 mu s. "tremor suppression" is placed at the edge switch connected to the operator. It suppresses physiological tremors, which improves the application's performance and also reduces the network load up to 99.9%. Our EdgeP4 framework allows edge intelligence modules to seamlessly switch between the algorithms based on the tasks being executed by devices connected to their ports.

We consider a microgrid system with sparse structure, where the security is susceptible to the impact of potential faults. To enhance the reliability and scalability of the microgrid system, this paper investigates the structured controller design problem for the microgrid system under fault conditions using chordal decomposition. By establishing a microgrid fault model with a sparse structure, the controller design problem for large-scale microgrid systems is decomposed into a set of smaller-scale problems using chordal decomposition, and then solved clique-by-clique in a sequential approach. The results demonstrate that this approach reduces the sensitivity of the microgrid system to faults and improves solution efficiency and scalability. © 2024 ieee.

2.5D chiplet systems have been proposed to improve the low manufacturing yield of large-scale chips. However, connecting the chiplets through an electronic interposer imposes a high traffic load on the interposer network. Silicon photonics technology has shown great promise towards handling a high volume of traffic with low latency in intra-chip network-on-chip (NoC) fabrics. Although recent advances in silicon photonic devices have extended photonic NoCs to enable high bandwidth communication in 2.5D chiplet systems, such interposer-based photonic networks still suffer from high power consumption. In this work, we design and analyze a novel Reconfigurable power-efficient and congestion-aware Silicon-Photonic 2.5D Interposer network, called ReSiPI. Considering run-time traffic, ReSiPI is able to dynamically deploy inter-chiplet photonic gateways to improve the overall network congestion. ReSiPI also employs switching elements based on phase change materials (PCMs) to dynamically reconfigure and power-gate the photonic interposer network, thereby improving the network power efficiency. Compared to the best prior state-of-the-art 2.5D photonic network, ReSiPI demonstrates, on average, 37% lower latency, 25% power reduction, and 53% energy minimization in the network.

With the rapid development of IoT and embedded technologies, the construction of smart wards has become a key focus in modern healthcare. This study aims to design a smart ward simulation system based on an ARM processor to address inefficiencies in traditional ward management, such as low manual monitoring efficiency and overlooked infusion monitoring. The system integrates multiple functional modules, including temperature and humidity monitoring, light intensity adjustment, infusion monitoring, call alarms, and fan control, creating an intelligent platform for ward environment management and patient status monitoring. By employing multi-sensor fusion technology for data acquisition and an incremental PID control algorithm for precise fan speed regulation, the system is tested using Proteus simulation software. Results indicate that all functional modules operate stably and respond quickly, ensuring ward comfort and safety while significantly improving the precision and efficiency of medical care. The system demonstrates advantages such as low cost and low complexity, providing strong technical support and theoretical basis for the practical deployment of smart wards. © 2024 ieee.

In engineering, the performance of data-driven transient stability assessment of power systems will continue to deteriorate due to factors such as communication delays and dense channel failures, as well as the problem of missing dense channel data. This paper proposes a transient stability assessment model based on Long Short Term Memory Graph Attention Network (LSGAT) to address this issue. After obtaining the mask matrix representing the observability of the system based on the original network topology and PMU configuration scheme, observable data is obtained through the mask matrix and the model is trained under any missing PMU condition;During the training process, the LSGAT network extracts spatial features of incomplete measurement data through a multi head attention mechanism, captures spatiotemporal correlations through a long short-term memory network, and enhances the model's learning ability for unstable samples using a focus loss function. The simulation results show that the proposed method can maximize the utilization of observable data, has high accuracy and strong robustness, and is not limited by network topology, making it easy to transfer. ©2024 ieee.

This paper presents the design and testing of a voice-activated cleaning system for home automation. The system allows users to control a floor cleaning robot using voice commands. The robot is equipped with a Bluetooth module and a microcontroller that processes the voice commands received from a mobile device. The user can give various voice commands such as "move forward", "move back", "turn right", "turn left", "clean", "rotate", and "stop"to control the robot's movements and cleaning functions. The system utilizes speech recognition technology to convert the voice commands into digital signals that are then transmitted to the robot's microcontroller. The robot's movements are controlled by servo motors, and it also has a camera for live video transmission and recording. The software is implemented using the Arduino IDE and embedded C programming. The system aims to provide a convenient and hands-free way of controlling a cleaning robot, reducing manual effort required for floor cleaning tasks. © 2025 ieee.

This paper considers the class of positive singular systems and provides a new approach to achieve stabilization and observer design with positivity constraints. First, the connection between singular systems and its equivalent input derivative systems is established and their positivity with stability properties are analyzed. Then, an algebraic transformation is introduced, which allows to eliminate the derivative inputs and to obtain an equivalent standard system. A careful mathematical derivation was performed to obtain closed-form expressions for the coefficient matrices of the resulting transformed system. Consequently, the design of positive stabilization of positive singular systems was made possible using the equivalent standard state space representation. Finally, the design of positive observer for positive singular system is provided. It is shown that a similar procedure is required to eliminate the input derivatives that appear in the output equation allowing the observer to be designed. Both positive stabilization and positive observer designs are formulated and solved in terms of LMIs. © 2024 ieee.
