However, these values do not give clear results for different geometries. For this reason, taking into the parameters of the slot geometry accounts for determining the stator and rotor leakage reactance values that are important in terms of obtaining more accurate results. This paper has investigated the stator slot permeance values of nine different stator slot structures commonly used in industrial type of three-phase squirrel cage induction motors for obtaining the best starting torque. The stator inductance and leakage reactance values were calculated for each stator slot structure. The change of starting torque of the induction motor has been analyzed by using the MATLAB code. As a result of the analysis, the stator slot structure, which gives the best starting torque, has been obtained. It has been also shown that a 16% improvement can be achieved by changing the stator slot structure at the starting torque. This increase in the starting torque will provide a great advantage for the motor’s acceleration versus a heavy load.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":"43 1","pages":"25-29"},"PeriodicalIF":1.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2019.2914959","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62193215","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}

IaaS suffers from several security concerns, such as hypervisor hijacking, virtual machine (VM) hopping, and account hijacking. With such a large percentage of enterprise traffic on the cloud, a strong security framework is demanded. To secure IaaS, this article proposes a software-defined perimeter (SDP) as a solution. SDP provides a logical perimeter to restrict access to services with a layer of authentication and authorization to allow. Only authorized clients may connect to services hidden by SDP gateways. SDP is implemented and verified in an AWS cloud environment. Port scanning is used to verify SDP behavior as well. The results demonstrate the SDP’s ability to “darken” services behind a gateway. The performance of SDP against a denial-of-service (DoS) attack is demonstrated in a local environment. The test results demonstrate that SDP is indeed capable of resisting DoS attacks while allowing legitimate user traffic even under the duration of the attack. These results lead to a discussion on future research for SDP in IaaS.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":"43 1","pages":"357-363"},"PeriodicalIF":1.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2020.3005316","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62193561","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}

It works over multiple modern and conventional data formats, such as JSON, SQL, Prolog, CSV, XLS, and XLSX. We present the syntax involved in the construction of our various flexible searching criteria and their personalizations. Furthermore, we present the architecture of this novel system that combines fuzzy, crisp data, and similarity relations in its queries to return constructive answers ordered by a degree of searching criteria satisfaction (truth-value between 0 and 1). Finally, we include a comparative analysis of different fuzzy querying systems here, and we provide various experiments, to show the system behavior, performance, efficiency, and scalability as well.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":"43 1","pages":"235-250"},"PeriodicalIF":1.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2020.2966733","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62193091","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}

Furthermore, this article aims to investigate the DVR performance when installed in a microgrid (MG) during both normal operation of the utility and during utility disturbances. One of the main objectives of this article is to reduce the cost of inverter-based DVR by reducing both the size of the dc-link capacitor and rating of switching elements. The voltage of the dc-link capacitor is regulated to low voltage level using a transformer and a pulsewidth modulation (PWM) rectifier to achieve both effective voltage regulation and drawing a sinusoidal line current from the grid and thus not to contribute to the increase of the THD of the utility current. Furthermore, the voltage across the switches can be limited to low value by an adequate design of dc-link capacitor size, capacitor voltage, and sag level to be compensated. Finally, the effectiveness and fast response of the proposed DVR for the compensation of voltage disturbances and current harmonics is confirmed by simulation using MATLAB/Simulink during the steady-state and transient operations to analyze the performance of the scheme under different operating conditions.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":"43 1","pages":"331-341"},"PeriodicalIF":1.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2020.3002855","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62193516","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 importance of this study stems from two facts. First, the simulation is a required stage of any design process including that of an IEC 61850 model of utilities, which may include an automation system from two or more vendors. Second, verification of the vendor’s claim to be compliant with a specific edition of IEC 61850 relies in part on the simulation. We validate the interfacing of the IEC 61850 generic object-oriented substation event (GOOSE) and sampled value (SV) packets through the I/O modules of the simulation environment. In addition, this protocol interfacing is applied to validate a distance protection relay model using the IEC 61850 modules of GOOSEs and SVs in the HYPERSIM real-time simulator taking advantage of an SGI parallel supercomputer. The distance protection relay is implemented in Simulink, tested and validated with MATLAB Simscape Power Systems and imported into HYPERSIM via the HYPERLINK module. The simulation result has been evaluated in terms of reliability and time delay which plays an important role for the communication and cyber systems in smart grids. This real-time simulation setup is valuable for prototyping, analysis, and validation of control algorithms compliant with IEC 61850.","PeriodicalId":55287,"journal":{"name":"Canadian Journal of Electrical and Computer Engineering-Revue Canadienne De Genie Electrique et Informatique","volume":"43 1","pages":"157-162"},"PeriodicalIF":1.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/CJECE.2020.2968404","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62193714","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}
