Background: For high computation, parallel and distributed processing chip multiprocessors are widely used. In chip multiprocessors, large on chip cache memories are used for performance improvement and speedy execution of the task. These cache memories consume 13% to 45% of the overall power consumed by the entire chip. As chip size shrinks with technology scaling, static energy consumed by the chip increases. T Read More

Background: This document presents a dual sliding mode vector control method to estimate speed and position of Permanent Magnet Linear Synchronous Motor (PMLSM). Methods: Firstly, the motor simulation model is built based on the mathematical model of PMLSM. For the sake of solving the problems of the jitter and position angle deviation in the traditional SMO, the inverse hyperbolic tangent function is used and Read More

Background: Circularly polarized (CP) antenna is an effective choice for wireless systems due to its insensitivity to the orientations of electromagnetic waves. Objective: A novel CP triangular patch antenna (CPTA) system is designed for ultra-wideband (UWB) applications. Methods: The CPTA, with a total size of 40.6 x 40.9 x 1.6 mm3, comprises a triangular patch positioned on the aperture of a V-shaped ground plan Read More

Introduction: This paper presents an approach for multistage expansion planning of the active distribution system network problems by considering multiple strategies based on system investment cost, including renewable energy sources based on distributed generation units, operational cost, and reliability. Objective: The developed framework model fulfills the prospects related to techno-economical and reliable multistage ex Read More

Objectives: In this paper, the performance of pulse position modulation (PPM), nonreturn zero modulation (NRZ), and return zero modulation (RZ) at signal-to-noise ratio and bit error rate in free space optical communication is compared. This comparison is performed to obtain the most effective modulation in atmospheric attenuations. Also, the effect of increasing transmitter power on the bit error rate and signal-to-nois Read More

Background: As the integration of communication networks with power systems is getting closer, the number of malicious attacks against the cyber-physical power system is increasing substantially. The data integrity attack can tamper with the measurement information collected by Supervisory Control and Data Acquisition (SCADA), which can affect important decisions of the power grid and pose a significant threat t Read More

Background: The challenges in real-time multithreading, particularly in the efficiency of multithreaded applications running concurrently on multiple cores, have evolved significantly due to the increase in IoT, cloud and edge computing applications. The continuous increase in cores depth adds further research issues related to the efficiency of such multicore systems and their applications. Therefore, further research is still requ Read More
