Its leaves possess medicinal properties and are used to treat various ailments. However, the effects of kratom extract in terms of biological domains are still concerning. Although considerable studies have been conducted on the effects of kratom usage over the last few years, no study using in silico analysis of kratom users’ electrocardiogram (ECG) has been reported to date. This study aims to examine the long-term effects of kratom consumption using the ECG signals and deep learning (DL) network and machine learning techniques. Raw ECG signals were used as input for training and detecting abnormalities, and a deep residual learning network (DRLN) model was implemented to develop a feature extractor from single-lead datasets; the extracted features were used to train conventional machine learning classifiers. The confounding ECG abnormality factors, namely, age, sex, smoking, alcohol consumption, and exercise, were analyzed for association using the chi-square test. The main results of our study showed that kratom usage is not associated with ECG abnormalities. However, the ECG signal was affected more by gender than by the other factors; it exhibited the highest sensitivity and specificity (score = 0.63). While this study is limited to ECG abnormalities, the results indicate that long-term usage of kratom for its health benefits may be considered a safe and natural practice.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 4","pages":"380-390"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138550240","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 main focus of SRM development has been enhancing efficiency while reducing torque ripple and losses. Given that this study aims to apply the proposed SRM design in electric vehicles, it is crucial to achieve a motor that is free from torque ripple and exhibits high efficiency. This research proposes a novel type of SRM called the outer rotor permanent magnet SRM (ORPMSRM) specifically for lightweight electric vehicles. Structural modifications are introduced in the ORPMSRM design to improve the torque characteristics and minimize losses. The electromagnetic analysis is conducted to predict the performance of the ORPMSRM with these modified structures. This article offers a comprehensive investigation that considers various configurations of rotor poles and stator poles with permanent magnets (PMs) to enhance the performance of the ORPMSRM. The finite element analysis (FEA) results are compared with experimental results, providing valuable insights into the motor’s performance and validating the analytical predictions.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 4","pages":"342-347"},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138550316","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}

Although IEEE 802.11p MAC performance has been investigated, analytical methods need improvement. Bit error and channel capture influence the performance of vehicular communications in real-world transmission. These effects are investigated separately in previous works. In this article, an extensive study is provided that integrates these two major factors. In VANETs, the influence of channel fading and capture on IEEE 802.11p is investigated analytically using a Markov chain model. For Nakagami-m, Rayleigh, and Rician fading channels, performance-impacting factors are considered, and the relationships between parameters as well as performance metrics are derived.

Although the influence of noise can be effectively addressed, it has become a popular research topic in mobile communications. Moreover, in recent telecommunication systems, owing to their complexity and comprehensive protocols, which require a large number of mathematical and engineering approaches, predicting and classifying noise is difficult. Thus, to effectively address these challenges, we propose a spatiotemporal AnoGAN to detect the noise that can occur during radio modulation. In our approach, we assemble a set of AnoGANs based on convolutional neural networks (CNNs) and long short-term memory (LSTM) to enable the system to learn the time-series features of the radio modulation signal and shape expressed in complex planes. The proposed spatiotemporal AnoGAN can discriminate the interference caused by noise without any annotation of anomalies using a generator and discriminator. The proposed spatiotemporal AnoGAN achieves a 91.4% recall in digitally modulated signals that were previously difficult to identify. Through an empirical analysis of the proposed method, we observed that the spatiotemporal AnoGAN accurately identified abnormal interference signals.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 4","pages":"310-321"},"PeriodicalIF":0.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138491037","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}

As a consequence, the tumor expands. It is hypothesized that a neural network can successfully identify and predict brain tumors, two of the most challenging medical problems now facing doctors. The abundance of information enhances the diagnostic potential of magnetic resonance imaging (MRI) which provides the anatomical features of brain tumors. To improve the efficiency of the semantic segmentation architecture, we introduce a novel transformer-based attention U-shaped network called TransAttU-Net, in which the multilevel guided attention and multiscale skip connection operate simultaneously and which is also used to extract the pixel on the tumor area. Initially, the input image data are altered and undergo further processing using various preprocessing techniques. Methods such as these can be used to resize or rescale features, data augmentation, reverse or flip data, and alter the orientation of data. These procedures are required before sending data to the TransAttU-Net deep learning (DL) model. The algorithm attained a degree of accuracy on the BraTS 2019, i.e., the dataset provided in multimodal brain tumor image segmentation challenge and BraTS 2020 dataset, indicating great performance on BraTS 2020 dataset.

The dc MG becomes prone to instability due to the excessive application of constant power loads (CPLs) and their variations. Under such conditions, the source-side control techniques for the stabilization of dc MG systems fail. Therefore, to stabilize dc MG systems, the load-side control methods are alternate approaches to improve the stability of dc MG. In this article, a new feed-forward control technique is proposed to improve the stability of the dc MG. In the proposed method, the input impedance of the load-side dc–dc converter is modified by the phase compensation method without realizing a total magnitude separation \u0000<inline-formula> <tex-math>$(Z_{text {os}}$ </tex-math></inline-formula>\u0000 and \u0000<inline-formula> <tex-math>$y_{text {iL}}=1/Z_{text {iL}}) $ </tex-math></inline-formula>\u0000 to stabilize the dc MG system. The investigation analyzes the possibility of instability across the operational frequency spectrum. Based on that, a new feed-forward loop compensator is derived, which is a function of the center frequency to make it adaptive to load variations. After that, the derived compensator is realized for voltage mode control of the buck converter. It reduces the dc MG bus voltage oscillations without increasing system complexity and dissipation. The results of the MATLAB® simulation are compared with suggested and existing control methods. Moreover, it was discovered that the ripple in bus voltage decreased from 5.28% to 0.7%. And the settling durations of dc bus voltage and current were lowered from 0.5 and 0.25 s to 0.25 and 0.16 s, respectively.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 4","pages":"288-297"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134891016","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}

In this study, we have developed a NIR diffuse optical breast scanning (DOB-Scan) probe and evaluated a new imaging method based on a modified diffusion equation (MDE) for breast tumor localization. The probe is applied to breast phantoms to collect reflectance or the intensity of backscattered light. To measure the optical properties of the phantoms, we also calculated the reflectance theoretically, where we initially utilized the original diffusion equation (DE) to arrive at the theoretical reflectance. However, the DE algorithm has several limitations, which require modification of the DE formula to match the experimental results before obtaining the optical properties. Finally, the imaging algorithm is used to map the optical properties to cross-sectional images, which can localize the abnormalities in the breast phantoms.
