The total size of the device is about 133 μm2. Plane-wave expansion and finite difference time domain methods are used to calculate the band diagram and simulation of the optical wave propagation inside the structure, respectively.

The proposed device is composed of silicon rods consisting of four optical waveguides and a defect in a PhC. Two well-known plane wave expansion and finite difference time domain methods are used to study and analyze photonic band structure and light propagation inside the PhC, respectively. The numerical results demonstrate that the ON-OFF contrast ratios are 16 dB for “Sum” and about 14 dB for "Carry".  They also reveal that the proposed half-adder has a maximum time delay of 0.8 ps with a total footprint of 158 µm2.

On the other hand, the variable nature of transmission line parameters due to weather conditions leads to misoperation and malfunction of fault detection and protection schemes of industrial relays in some cases. This paper, for the first time, presents a BCF location scheme without requiring line parameters data and only using magnitudes of current and voltage phasors of a single terminal based on Group Method of Data Handling (GMDH). In this method, a function is interpolated, the inputs of which are the current and voltage of the faulty phase, and its output are the accurate location of the fault.

In this context, the privatization of power systems, as well as flexible sources like electrical vehicles and storage systems, has been enhanced significantly by the advent of microgrids. In a microgrid structure, the microgrid’s operator coordinates the agents and ensures the reliability of the network, while the agents manage their local resources independently. Nonetheless, new management methods should be implemented into the multi-agent-structured microgrids to meet their distributed nature. This paper proposes a new peer-to-peer energy market to optimize the operation of a multi-agent microgrid run in the isolated mode.

Even though lots of acceleration designs are proposed for different sequencing methods, several crucial drawbacks impact these methods. One of these difficulties stems from the difference in read lengths that may take place as input data. In this work, we propose a new Race-logic implementation of the seed extension kernel of the BWA-MEM alignment algorithm. The first proposed method does not need reconfiguration to execute the seed extension kernel for different read lengths. We use MEMRISTORs instead of the conventional, complementary metal-oxide-semiconductor (CMOS), which leads to lower area overhead and power consumption. Also, we benefit from Field-Programmable Nanowire Interconnect Architecture as our matrix output resulting in a flexible output that bypasses the reconfiguration procedure of the system for reads with different lengths. Considering the power, area, and delay efficiency, we gain better results than other state-of-the-art implementations. Consequently, we gain up to 22x speedup compared to the state-of-the-art systolic arrays, 600x speed up considering different seed lengths of the previous state-of-the-art proposed methods, at least 10x improvements in area overhead, and 105x improvements in power.}, keywords = {Bioinformatics,BWA-MEM,memristor,Race logic}, url = {https://jaree.scu.ac.ir/article_16836.html}, eprint = {https://jaree.scu.ac.ir/article_16836_38ffbc48d96e29cd6f41fa470297c9eb.pdf} } @article { author = {Farahmand, Ebrahim and Mahani, Ali}, title = {A Novel Energy-Efficient Weighted Multi-Level Clustering Protocol}, journal = {Journal of Applied Research in Electrical Engineering}, volume = {1}, number = {1}, pages = {69-78}, year = {2022}, publisher = {Shahid Chamran University of Ahvaz}, issn = {2717-414X}, eissn = {2783-2864}, doi = {10.22055/jaree.2021.36169.1019}, abstract = {Wireless sensor networks (WSNs) consist of a large number of sensor nodes that allow users to accurately monitor a remote environment by aggregating the data from the individual nodes.

The newly introduced countermeasure is a fault correction scheme based on DMR technique (FC-DMR) combined with a version of the time redundancy technique. In the proposed architecture, when a transient random or malicious fault(s) is detected in each pipeline stage, the error signal corresponding to that stage becomes high. The control unit holds the previous correct value in the output of our proposed DMR voter in the other pipeline stages as soon as it observes the value ‘1’ on the error signal. The previous correct outputs will be kept until the fault effect disappears. The presented low-cost HFS-box provide a high capability of fault resistance against transient faults with any duration by imposing low area overhead compared with similar fault correction strategies, i.e. 137%, and low throughput degradation, i.e. 11.3%, on the original S-box implementation.}, keywords = {Fault-Resistant,Advanced Encryption Standard (AES),S-box,High-speed}, url = {https://jaree.scu.ac.ir/article_16857.html}, eprint = {https://jaree.scu.ac.ir/article_16857_5f6907ade552a3748ef457ad496a459b.pdf} } @article { author = {Rezaei, Shabnam and Ghasemi, Ahmad}, title = {Optimal Day-Ahead Scheduling of a CHP and Renewable Resources-Based Energy Hub with the Aim of Improving Resiliency During Input Energy Carriers’ Outage}, journal = {Journal of Applied Research in Electrical Engineering}, volume = {1}, number = {1}, pages = {93-111}, year = {2022}, publisher = {Shahid Chamran University of Ahvaz}, issn = {2717-414X}, eissn = {2783-2864}, doi = {10.22055/jaree.2021.36613.1023}, abstract = {This paper proposes a novel day-ahead energy hub scheduling framework aimed at improving resiliency.

Outage of input energy carriers causes failure of devices in the energy hub, loss of electrical loads, failure in cooling and heating and thus reduced resiliency. Maintaining the security of the hub consumers’ power supply system in the event of such severe disturbances is essential. Therefore, a new strategy based on the use of backup electric energy storages (EES) and DR program is proposed in this paper to improve resiliency.
