In the suggested design, a common ground not only reduces the CMV-HF but also improves dc-link voltage usage. While comparing with traditional two-stage FL-APC dc–ac converter, the proposed design has lower voltage stresses and greater uniformity. While improving overall efficiency, the suggested clamped dc–ac converter saves three power switches and a capacitor.

{"title":"On the Packet Decoding Delay of Linear Network Coded Wireless Broadcast Sur le délai de décodage des paquets de la diffusion sans fil codée par réseau linéaire","authors":"Mingchao Yu;Alex Sprintson;Parastoo Sadeghi","doi":"10.1109/ICJECE.2022.3210237","DOIUrl":"https://doi.org/10.1109/ICJECE.2022.3210237","url":null,"abstract":"We apply linear network coding (LNC) to broadcast a block of data packets from one sender to a set of receivers via lossy wireless channels, assuming that each receiver already possesses a subset of these packets (through previous systematic transmissions) and wants the rest. We aim to characterize the average packet decoding delay (APDD), which reflects how soon each data packet can be decoded by each receiver on average, and to minimize it without sacrificing throughput. To this end, we first derive closed-form lower bounds on the expected APDD of LNC techniques. We then prove that determining whether these lower bounds are tight is NP-hard and so is APDD minimization. We then prove that every throughput-optimal LNC technique can approximate the minimum expected APDD with a ratio between 4/3 and 2 and that this ratio is exactly 2 for random LNC (RLNC). We also show that instantly decodable network coding (IDNC) techniques cannot approximate APDD due to suboptimal throughput. Finally, we propose hypergraphic LNC (HLNC), a novel throughput-optimal and APDD-approximating technique based on a hypergraphic model of receivers. Our simulations show that the APDD of HLNC significantly outperforms existing techniques, including RLNC, under all considered settings without any sacrifice on throughput. Résumé—Nous appliquons le codage linéaire de réseau (LNC) pour diffuser un bloc de paquets de données d’un émetteur à un ensemble de récepteurs via des canaux sans fil avec pertes, en supposant que chaque récepteur possède déjà un sous-ensemble de ces paquets (par des transmissions systématiques précédentes) et veut le reste. Nous cherchons à caractériser le délai moyen de décodage des paquets (APDD), qui reflète la rapidité avec laquelle chaque paquet de données peut être décodé par chaque récepteur en moyenne, et à le minimiser sans sacrifier le débit. À cette fin, nous dérivons d’abord des limites inférieures en forme fermée sur l’APDD attendu des techniques LNC. Nous prouvons ensuite déterminer si ces limites inférieures sont serrées, NP-hard et que la minimisation de l’APDD l’est aussi. Nous prouvons ensuite que chaque technique LNC optimale en termes de débit peut approximer l’APDD minimum attendu avec un rapport entre 4/3 et 2 et que ce rapport est exactement 2 pour les LNC aléatoires (RLNC). Nous montrons également que les techniques de codage de réseau instantanément décodable (IDNC) ne peuvent pas approximer l’APDD en raison d’un débit sous-optimal. Enfin, nous proposons le LNC hypergraphique (HLNC), une nouvelle technique d’optimisation du débit et d’approximation de l’APDD basée sur un modèle hypergraphique des récepteurs. Nos simulations montrent que l’APDD de HLNC surpasse de manière significative les techniques existantes, y compris RLNC, dans tous les paramètres considérés sans aucun sacrifice sur le débit.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"46 1","pages":"77-89"},"PeriodicalIF":0.0,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68038581","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 location prediction of mineral reservoirs like oil, gas, or metals in deep water is a challenge during the extraction of these resources. Moreover, the problem of ores and mineral deposits on the seafloor comes into play. The abovementioned challenges necessitate for the deployment of underwater wireless sensor networks (UWSNs). Anchor-based localization techniques are segregated into range-free and range-based processes. Range-based schemes depend on various techniques like angle of arrival (AoA), time of arrival (ToA), time difference of arrival (TDoA), and received signal strength indicator (RSSI). In this article, the localization of these leakages is performed by using range-based metrics for calculating the distance among anchor nodes (ANs) and target nodes (TNs). This estimated distance is further optimized to minimize the estimation error. A multilateralism procedure is used to estimate the optimal position of each TN. The results exhibit that the proposed algorithm shows a high performance when compared to previous works, in terms of minimum energy consumption, lower packet loss, rapid location estimation, and lowest localization error. The benefit of using the proposed methodology greatly impacts on identifying the leakage area in mobility-assisted UWSN, where rapid reporting helps to lower the loss of resources.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"45 4","pages":"466-474"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/9349829/9961098/10002839.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68030721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly, a permanent magnet brushless direct current (BLDC) motor possesses numerous merits such as high power density, and low torque ripple. However, this SRM and permanent magnet BLDC motor suffer from torque ripple and cogging torque, respectively. Therefore, this research article enriches the design procedure and characteristics of a 3-kW, 60-V hybrid reluctance motor with minimum torque ripple and vibration. Furthermore, this proposed motor is modeled and analyzed with various laminating core materials such as 47F165, Arnon 7, M420-50D, M300-35A, 36F155, and M-27 24Ga for identifying the superior material by considering the relevant parameters such as losses and torque. In the proposed doubly salient motor, a vibration analysis is also performed to predict its natural frequency. A laboratory arrangement is implemented to examine the proposed motor at no-load conditions. Then no-load current and vibration frequency were measured by a digital storage oscilloscope and accelerometer, respectively. These experimental outcomes are compared with finite-element analysis and analytical equations to validate findings.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"45 4","pages":"454-465"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68030080","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}

Unlike previous efforts, we consider the realistic behavior of radio resource heads (RRHs) associated with one baseband unit (BBU), acting as a distributed antenna system (DAS). We first formulate the admission control (AC) and the RRH–BBU mapping problem, subject to constraints on user throughput requirements, computational capacity in the BBU pool, and according to the assumption of DAS behavior. As the optimal solution is practically intractable for large-scale dynamic networks, we propose a two-level resource allocation framework, based on two developed algorithms: a first one for AC at the radio level and a second one for RRH–BBU mapping at the computational level. The two algorithms are designed to allow both the levels to consider each other’s constraints and particularities. Results obtained from an extensive simulation-based performance evaluation show the high performance of our proposal in terms of radio-related metrics, number of accepted users, power saving, and energy and spectrum efficiency, compared with three baseline reference schemes.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"45 4","pages":"442-453"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68030082","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 overhead transmission line operates in a very complex terrain thereby making it vulnerable to various kinds of faults. Most transmission line faults lead to interruption in power supplies and therefore the need for a fast repair to restore the system to its normal state. A fast, timely, and accurate fault detection technique will ensure speedy restoration of the system thereby reducing outage time. In this article, an enhanced transmission lines’ fault detection approach is presented. This scheme deployed a highly sensitive, low cost, and energy-efficient differential sensor to detect flux density variation measured along transmission lines. The fault detection algorithm is developed for the detection of faults in transmission lines. The development is implemented on a model transmission line and tested for various fault scenarios. Scaled-up laboratory experiments were also conducted to measure magnetic flux density and fault identification to verify the validity of the proposed technique as well as estimate the amount of current produced when a fault occurred. From the simulated and measured current produced during a fault, the proposed technique yielded an estimated error of 1.38%, while the CT and a commercial current probe gave errors of 10.99% and 17.68%, respectively.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"45 4","pages":"409-417"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68030085","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}

Since the past few years, one of the key control schemes to enhance the effectiveness of the microgrid is the observer-based MPPT control. This article proposes a higher order sliding mode observer (HOSMO)-based integral sliding mode control (ISMC) for MPPT control to ensure an efficient operation of a closed-loop dc microgrid. The proposed MPPT control is mainly focused on obtaining a chatter-free output voltage and stabilized output power from the PV-system-based microgrid and further ensure insensitivity to uncertainties and reduction in steady-state error. ISMC is applied to carry out finite-time stabilization throughout the entire response of the system. To justify the efficacy of the proposed approach, various test scenarios are simulated in real-time, and the performance is investigated through extensive comparative results. The MATLAB simulations and real-time simulation results achieved with OPAL-RT are compared. The superior performance of the proposed approach is observed in terms of high efficiency, good accuracy, and robust performance under varying meteorological conditions.","PeriodicalId":100619,"journal":{"name":"IEEE Canadian Journal of Electrical and Computer Engineering","volume":"45 4","pages":"418-425"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68030084","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}

First, the parameters of the nonlinear model of the transmitter and finite impulse response (FIR) of the wireless multipath channel are estimated with the Hammerstein system parameter separation technique. Second, the best IQ imbalance parameter combination is obtained with the FIR estimation of the channel. Finally, the estimated parameters of the nonlinear model and IQ imbalance are used as RFFs to classify the transmitters.
