The proposed design utilizes a single-layer substrate integrated waveguide (SIW) fractal Koch snowflake (FKS) slot antenna array. The main focus is on achieving wideband characteristics and self-isolation among antennas without using any additional isolation circuits. The method is described to obtain the wideband performance of the SIW FKS slot antenna array fed with a grounded coplanar waveguide (GCPW). The radiation performance of single-element and quadrilateral elements is analyzed. The simulation and measurement results demonstrate that the MIMO antenna elements exhibit a bandwidth of 27.1–32.4 GHz (17.8%) and peak gain of 8.3 dBi at 28 GHz. The achieved isolation levels are greater than 23 dB (simulated) and 20 dB (measured), with a self-isolation structure. Furthermore, this work extended to calculate diversity characteristics of proposed MIMO, such as the envelope correlation coefficient (<inline-formula> <tex-math>$text {ECC} lt 0.005$ </tex-math></inline-formula>), mean effective gain ratio (<inline-formula> <tex-math>$text {MEG} lt 1.1$ </tex-math></inline-formula>), diversity gain (<inline-formula> <tex-math>$text {DG}lt 9.9$ </tex-math></inline-formula> dB), and channel capacity loss (<inline-formula> <tex-math>$text {CCL}lt 0.3$ </tex-math></inline-formula> bits/s/Hz). These results validate that the proposed MIMO antenna design is performing satisfactorily. The fabricated prototype measurement results are validated with simulation results.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"48 1","pages":"52-59"},"PeriodicalIF":2.1,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed technique is well suited for higher power applications that require two galvanically isolated and synchronous gate drive signals. The proposed gate driver can achieve very fast turn-on and turn-off transitions, due to its current mode nature. In addition, this technique can achieve partial gate energy recovery by recovering a part of the rms (<inline-formula> <tex-math>$CV^2$ </tex-math></inline-formula>) energy, which is typically dissipated over the gate drive resistors in voltage source gate driver (VSGD) techniques. The proposed ICSGD provides better control over the gate charging and discharging process as it allows the engineers to carefully time the turn-on/turn-off transitions. It provides superior performance over its VSGD counterparts, especially in high-frequency (HF) operations. The digital implementation of the proposed circuit using Typhoon’s HIL platform proves highly effective for evaluating design reliability and testing design parameters in realtime, enabling comprehensive validation prior to physical implementation. The HIL system is implemented on Typhoon’s HIL402 module. The control algorithm is implemented on a Texas Instruments F28335 digital signal processor (DSP), which is then integrated with the HIL402 module using a Typhoon HIL DSP interface. The model is verified with a match of results from PSIM and Typhoon. The PSIM & HIL results show that the ICSGD achieves a minimum of 20% efficiency improvement.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"48 1","pages":"29-39"},"PeriodicalIF":2.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143360972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, the potential of polarimetric enhancement and deep learning (DL) techniques in ship wake detection still remains to be further discovered. In this article, first, the polarimetric enhancement methods based on the polarimetric whitening filter (PWF) and polarimetric detection optimization filter (PDOF) have been researched. Since the measured full-polarized synthetic aperture radar (SAR) images of ship wake are rather limited and inadequate for DL techniques, a full-polarized wake detection dataset (FPWDD) has been established for the first time. It was constructed based on 6000 simulated polarimetric SAR (PolSAR) images of a typical small surface vehicle, including four kinds of target numbers, five kinds of wind speeds, five kinds of wind directions, five kinds of ship velocities, and 36 kinds of ship heading angles. It is composed of two kinds of images: the full covariance matrixes stored in the TIF format and the images after the Pauli decomposition stored in the RGB format. Furthermore, the ship wake detection has been performed based on the FPWDD and three widely applied target detection DL networks for the HH, HV, VV, PWF, and PDOF channels. Finally, an analysis of the wake detection performances of the five channels has been carried out, which has proved that the polarimetric enhancement methods can obviously enhance the wake detection performance of small surface vehicles, with most evaluation metrics about 10% higher than that of HH, VV, and HV.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"48 1","pages":"19-28"},"PeriodicalIF":2.1,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143360895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such a system has found numerous applications in power systems. One such application is power hardware-in-the-loop (PHIL) simulation. In the context of PHIL simulation, a hardware device under test (DUT) is typically linked to a digital real-time simulator (DRTS) via a PHIL interface. Over time, several PHIL interfaces have been proposed and explored. Notably, the ideal transformer model (ITM) stands out due to its popularity, primarily for its ease of implementation. Other PHIL interfaces, such as partial circuit duplication (PCD) and damping impedance, can be viewed as extensions of the ITM concept. These PHIL interfaces necessitate a strict impedance ratio between the physical (i.e., the DUT) and the cyber parts (i.e., the system modeled in DRTS) before embarking on a PHIL implementation. This prerequisite can often prove to be a demanding and complex task. This article introduces a novel PHIL interface for PHIL using Nelder–Mead (NM) algorithm, designed to eliminate such constraints. Notably, the proposed PHIL interface offers an expanded stability region when compared with ITM, thus rendering it suitable for a broader range of PHIL applications. The effectiveness of this proposed method has been confirmed by a practical PHIL setup.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"48 1","pages":"10-18"},"PeriodicalIF":2.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143360894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further EV charging systems that function during the daytime in multistorey buildings expedite the peak loading. The main objective of this work is to minimize the operating cost of the system and conversion losses. In this work, the microgrid incorporated with a bidirectional converter plays a major role in dc-ac and ac-dc conversion. The photo voltaic (PV) sources support the system with sufficient dc power generation and batteries store the dc power and supply the load in case of insufficiency. By utilizing a genetic algorithm (GA) and appropriate energy management (EM) to charge EVs according to time-of-use tariff patterns, the impact of growing demand on the grid is greatly mitigated. To ease the burden on the grid during peak hours, the interruptible loads are shifted to off-peak times. Other challenges of EV charging such as energy saving, maximum peak demand, voltage instability, and high current drawing issues are rectified and well presented with existing topology. When compared to the standard scheme, the energy savings in the proposed topology are much increased, reaching 33.04%, while the cost reduction is 57.27%.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"47 4","pages":"250-259"},"PeriodicalIF":2.1,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Internet of Medical Things (IoMT) systems facilitate the seamless transfer of health records to data centers, allowing medical professionals and caregivers to analyze, process, and access them. This data is often stored in cloud-based systems. Nevertheless, the transmission of data and execution of computations in a cloud environment may lead to delays and affect the efficiency of real-time healthcare services. In addition, the use of edge computing (EC) layers has become prevalent in performing local data processing and storage to reduce service response times for IoMT applications. The main objective of this article is to develop an adaptive EC infrastructure for IoMT systems, with a specific emphasis on maintaining optimal performance for real-time health services. It also designs a model to predict the server resources required to meet service level agreements (SLAs) regarding response time. Simulation results demonstrate that EC significantly improves service response time for real-time IoMT applications. The proposed model can accurately and efficiently predict the computing resources required for medical data services to achieve SLAs under varying workload conditions.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"47 4","pages":"242-249"},"PeriodicalIF":2.1,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
