This paper presents an experimental analysis of a stepped-frequency continuous wave (SFCW) software-defined radar (SDR) system. The system utilizes a USRP N210 with WBX daughterboard, a standard gain horn antenna, a waveguide antenna, and a personal computer. Operating with a bandwidth of 560 MHz, a frequency step size of 20 MHz, and 28 steps, the system's performance is evaluated through range profile analysis. Experimental trials involve transmitting SFCW signals and collecting corresponding echoes for target responses at distances of 0.7 meters, 0.9 meters, and 1.25 meters. The analysis of the range profile reveals distinct target signatures, demonstrating the system's effectiveness for target detection at varying distances.

This paper proposes a distributed real-time state estimation(RTSE)method for the combined heat and power systems(CHPSs).First,a difference-based model for the heat system is established considering the dynamics of heat *** heat system model is further used along with the power system steady-state model for holistic CHPS state estimation.A cubature Kalman filter(CKF)-based RTSE is developed to deal with the system nonlinearity while integrating both the historical and present measurement ***,a multi-timescale asynchronous distributed computation scheme is designed to enhance the scalability of the proposed method for largescale *** distributed implementation requires only a small amount of information exchange and thus protects the privacy of different energy *** carried out on two CHPSs show that the proposed method can significantly improve the estimation efficiency of CHPS without loss of accuracy compared with other existing models and methods.

Automation has revolutionized scientific research, particularly in cell culture, where it enhances efficiency and minimizes variability. Traditional cell culture faces challenges, often leading to stress-induced cell senescence. To address these challenges, we are developing an enclosed, automated system with a robotic fluid handling system and 60 independent bioreactors. Aiming for clinical applications, the system is required to maintain tight environmental control for optimal cell culture conditions. This paper reports on the development of the control system for maintaining the gaseous carbon dioxide $\left(\mathrm{CO}_{2}\right)$ concentration within the enclosed system. In particular, we develop a predictor feedback CO 2 controller to regulate the CO 2 concentration. A baseline traditional feedback controller is also implemented for comparison. This work contributes to advancing automated cell culture systems, emphasizing the importance of precise environmental control for higher-quality cell cultures. The developed predictor feedback CO 2 controller offers a promising control solution to reducing stress-induced variations and will be suitable for clinical applications.

The smart grid has stacked ICT power equipment. Smart grids use modern electrical sensors. Future adoption of smart devices and their interaction with networks may offer cyberthreats. Several smart grid subsystems may be exposed if a component doesn't respond in real time, reducing efficiency and reliability. Superannuated networks create cyber security risks. This article explores a secure cyber infrastructure, related breakthroughs, and cyber security concerns in a complex system. Cybersecurity goals, objectives, and risk assessments are complete. These papers are summarized. Prioritize security. Then, examine smart grid hacks to uncover weaknesses and their repercussions.

Different types of heterogeneous multiple service robots are working in the same environment to help humans in many ways in a smart house. These service robots have different capabilities based on the different control and communication systems. The complexity of the programming of the robots is now reduced by using middleware like Robot Operating system (ROS). However, the communication and control of the heterogeneous service robots using very high-level instruction is still tricky because of differences in ROS topics. If a user has issued a high-level instruction to all multiple heterogeneous robots in the same environment, then all robots must complete the given task without considering the software differences in each robot. This research has developed a web-based interface where users can input high-level instruction to all multiple heterogeneous robots running in the same environment. We have used three levels of instructions. Level 01 moves robot forward for the given speed for some distance without obstacles. Level 02 is to move the robot to a specific location without obstacles. Level 03 is to navigate the robot to a goal with some obstacles in the environment. Initially, all robots need to register their software specifications and hardware specification Format (URDF) in the robot registration engine with the help of the ontology. Then all service robots act according to the instruction given by the interpreter. The proposed system was evaluated using a simulated environment with a gazebo using "Turtlebot"and "Tiago"robots. Time complexity analysis of all algorithms was completed using the Big O notation. © 2022 IEEE.

The most important branch of quantum telecommunications is quantum teleportation because in this branch we transmit what we do not know and all about its content without sending any qubits and using only quantum entanglement. In recent years, many designs have been proposed in this field, which are usually not in the hands of users from the beginning, such as the first design of channel qubits, these qubits are transmitted using quantum channels, so establishing security or authentication of users is important. In this paper, we will present a design with an authentication step that is transmitted from the sender simultaneously to 2 unknown qubit receivers, two different qubits. This plan also has 2 controllers for licensing and security review of protocol and destruction of channel qubits in case of error.

The objective of this study is to develop an exams item bank management system on the internet. The exam item analysis system is used to determine the reliability of the exams using K-R 20 and K-R 21 formulas. The difficulty and power of discrimination values are determined using a choice analysis and percentages of high and lower groups technique. The create exams set system can be performed randomly or identified through the difficulty level. The examination can be performed online and the exam results can be immediately announced. The grading system is used to support the decision-making to evaluate learning achievement. The system's accuracy was tested and found to be accurate compared with the hand calculation results. The system was tested with a sample group and satisfaction was assessed through questionnaires. The satisfaction of teachers and students was highest, while that of administrators was high. The developed exams item bank management system operates as a web application with a security system for supporting in learning activity. © 2023 IEEE.

Branches of quantum telecommunications are the branches that transmit information using quantum technologies. In some of these branches, quantum information is transmitted, and in others, classical information. The quantum teleportation branch is a branch that transmits an unknown qubit without sending qubits and using entanglement. The branches of quantum direct communication, quantum secret sharing, quantum dense coding, quantum dialogue, etc. are branches that transfer classical bits. In this paper, we intend to present a design that transmits both unknown qubits and 2 bits of classical messages in two directions and simultaneously by using the entanglement and technology of quantum teleportation.

Quantum Broadcast is an important branch with the ability to send known qubits to more than one quantum user. This feature states that a qubit can be transferred using entanglement between qubits without sending even a single qubit of information. This is a miracle today. This paper introduces a new branch in the field of quantum broadcast, the efficiency of which does not change from previous designs, but has two unique new features. First, it is the first quantum broadcast scheme based on entanglement displacement. Second is the first quantum broadcast scheme, which transmits a state similar to Bell entangled states instead of a simple single qubit state.
