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.

Increasing energy demands and the need for efficient management necessitate innovative solutions. This study introduces an integrated Demand Side Management (DSM) framework tailored for residential buildings within smart grid systems. The proposed methodology employs Earth Worm Optimization Algorithm (EWOA) and Virulence Optimization Algorithm (VOA) to optimize scheduling for household appliance using integration of Renewable Energy Storage (RES) and Renewable Energy Resources (RERs). Real-Time Electricity Scheduling (RTES) is implemented using IoT technologies to enable adaptive energy management. This system demonstrates significant performance improvements, achieving a 76.19% reduction in the Peak-to-Average Ratio (PAR) using VOA and a 73.8% reduction with EWOA when RES is included. Comparative analyses highlight substantial cost reductions, enhanced grid stability, and improved energy efficiency. This work not only showcases the novelty of integrating advanced optimization algorithms with IoT but also provides a robust approach to achieve sustainable and cost-effective energy management.

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.

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.
