Sarlan","doi":"10.37394/232027.2024.6.11","DOIUrl":"https://doi.org/10.37394/232027.2024.6.11","url":null,"abstract":"The Internet of Things (IoT), which enables seamless connectivity and communication between gadgets and the internet has completely changed how people interact with and use technology in 5G. Distributed Denial of Service (DDoS) assaults are now recognized as a serious security concern because of the rapid expansion of IoT devices, which has also brought about new security issues. DDoS attacks plan massive, coordinated attacks that overwhelm target systems and impair their functions by taking advantage of the interconnectedness of IoT devices. This paper explores the vulnerabilities in IoT devices and their possible exploitation by hostile actors, providing an in-depth examination of IoT and DDoS assault dynamics in 5G. The report emphasizes the need for preventative security measures by highlighting the growing size and complexity of DDoS attacks employing compromised IoT botnets. The examination of various DDoS attack channels and methodologies against IoT devices sheds light on the growing strategies used by attackers to infiltrate and manage IoT botnets. To emphasize how urgent it is to mitigate such risks, the effects of DDoS assaults on vital infrastructures, companies, and end-users are also emphasized. The paper also evaluates current mitigation techniques and security safeguards intended to counter IoT-based DDoS attacks. These include the use of security in Nexus that prioritize device authentication, encryption, and secure communication protocols as well as network traffic filtering and anomaly detection. Relevant case studies and real-world examples are provided to give readers a thorough understanding of the topic while demonstrating the scope and effects of recent IoT-based DDoS attacks. The paper guides different approaches through which DDOS can harm the server/ system (or anything, which is belonging to the family of the Internet of things) through different types; DDOS can be minimized but impossible to overcome. In this paper, we also have proved that due to IOT, the ratio of DDOS has increased by implementing these measures and continuously monitoring the network for potential threats. 5G systems can enhance their security posture and provide a safer and more reliable communication infrastructure for users and businesses by mitigating DDoS.","PeriodicalId":475274,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"21 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140378740","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}

Major security concerns have been rising up since malicious modification of hardware or fabrication IC can lead to an altered functional behavior, potentially with disastrous consequences in safety-critical applications. Due to the stealthy nature of the hardware Trojans the conventional design and time verification and post manufacturing testing cannot be readily extended. There are a large number of possible instances and operating modes for the hardware Trojans in a digital system. Since the hardware Trojan insertion can modify the functionality of the digital integrated circuit (IC), alter its behavior, generate denial of service (DoS), the HT threats should be analyzed with maximum importance through the entire lifecycle of the IC.","PeriodicalId":475274,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"12 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140230610","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, counterfeit currency has an impact on the economy and diminishes the value of genuine currency. Therefore, it is essential to detect the counterfeit currency. The majority of previous methods rely on hardware and image processing techniques. Using these methods to detect counterfeit currency is inefficient and time-consuming. We have proposed a system for the detection of counterfeit currency using a modified faster region-based convolution neural network (Faster R-CNN) to circumvent the aforementioned issue. This study identifies counterfeit currency by analyzing images of currency. One thousand images of currency note are used as dataset to train a Faster-RCNN model on inception V2 architecture to learn the feature map of currencies. Upon successful training and validation of the model, 500 images of counterfeit currencies were used to test the model. The proposed method efficiently identifies 96% of counterfeit currency images tested. Other evaluation means such as mean average precision and detection accuracy show that the developed system has an accuracy of 97%.","PeriodicalId":475274,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"132 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140480604","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}

Grid operators’ grid regulations require wind turbines to recover from grid disruptions and help maintain electricity networks. Having wind turbines equipped with fault current limiters (FCLs) may ensure their continued functioning in the event of a power loss. In this piece, we will talk about how to improve the two most common types of variable-speed wind turbines: the Doubly Fed Induction Generator (DFIG) and the Permanent Magnet Synchronous Generator (PMSG). Both wind generators were evaluated using the Thyristor Controlled Series Compensator (TCSC) with ANFIS and Fuzzy Logic. It is important to understand the dynamic behavior of wind turbines, hence models of their FCLs were built for steady state and grid disruptions. Power interruptions switched the FCLs in both wind turbines utilising grid voltage variation. Both wind turbines underwent a no-control FCL scenario. Both wind turbines’ FCLs were measured and compared under load from a severe three-phase to ground failure at their terminals. Both wind turbines were operated under similar circumstances to examine FCL control tactics during power interruptions.","PeriodicalId":475274,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"31 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140482660","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 design depends on the Arduino Uno board and Scilab software. Three Scilab block diagrams were given to simulate three magnetic tests, which are constant field block diagram (single field value), increasing and decreasing fields for FMR and magnetocaloric tests, and field for hysteresis loop test. Each Scilab block diagram contained different xcos blocks to control the Arduino output voltage and other blocks to sense, read, and calibrate the field value. This control was done via controlling pulse width modulation in the range (0-255). The output of each block diagram was simulated by measuring its variation with time using a cscope block display. The Arduino signal was amplified by a simple electronic circuit that involved two stages, BUL680 transistor as the first stage. Two high-power transistors EVK71-050 or Q50z were used in the second stage. The output of 107V-39.8A from the first one and 108V- 39.7A from the second one produces a magnetic field of about 30000Oe. The linearity between the current and the field value is better for Q50z due to the variation of α with the wide variation of collector current.","PeriodicalId":475274,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"340 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140483434","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}

Maged","doi":"10.37394/232027.2024.6.1","DOIUrl":"https://doi.org/10.37394/232027.2024.6.1","url":null,"abstract":"SBI stands for switched-boost inverter and is a single-stage power converter used to connect low-power sources, such as solar photovoltaic (PV) arrays within a modified nanogrid, to loads. Despite its many benefits, such as the fact that it does not require expensive sophisticated dead-time circuitry, its duty ratio is limited to between 0 and 0.5. As a result, this publication is a contribution towards improving the SBI's performance for use in a modified nanogrid. Furthermore, it also presents a revolutionary strategy for a simple closed-loop control technique that overcomes the majority of inverter shortcomings and system nonlinearity. The suggested robust controller uses a metaheuristic optimization technique, called gorilla troops optimization (GTO), to optimize the performance of this controller. The robustness of the suggested controller is tested against the sudden change of the nanogrid input voltage (i.e., PV-voltage), modulation index of the inverter, and the step-change in DC-link output voltage of the inverter. The test results obtained from Matlab/Simulink software are compared with particle swarm optimization (PSO) – as another optimization algorithm. Furthermore, the proposed system is experimentally implemented with OPAL RT-4510v real-time hardware in the loop (HIL), rapid control prototyping, OP-8660 HIL controller and data acquisition platform.","PeriodicalId":475274,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"75 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140505636","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}
