These mechanical influences usually occur during the operation of motors, gearboxes, rotating unbalanced masses. The resonant frequencies and other mechanical characteristics depend on the mounting option of the printed circuit boards (PCBs).Poorly fixed printed circuit boards will bend, and eventually, after the occurrence of first microcracks and then cracks, it will crack or break. The attachment points are subject to severe mechanical loads in case of sudden impacts and temperature fluctuations that the printed circuit board constantly experiences. As a rule, breaks are observed in the attachment points. Previous studies did not consider the relationship between mechanical stress and methods of installing PCBs. Through our research, we improved the model of the PCB by adding fixing points inside the plate, finding the optimal design and the mathematical equation for calculating the natural frequency. It turns out that the least preferred option is to mount the board with points that have coordinates, with the ratio’s a/4 and b/4, where a and b represent the length and width of the printed circuit board. Also recommended that to avoid placing electronic components near edges and attachment points, as they are more susceptible to fatigue. After determining the optimal design and selecting the first model through simulation using PTC Creo Parametric 7.0 validation and comparative results are obtained, and this approach can significantly improve the efficiency of the PCB design process.","PeriodicalId":354985,"journal":{"name":"2021 4th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126609259","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}

This noise can significantly affect the reliability of the communication link. Therefore, given the distinct characteristics of NOMA, this article proposes a multistage clipping approach for the mitigation of impulsive noise in orthogonal frequency division multiplexing (OFDM)-NOMA systems. Moreover, for each stage, considering the weighted combination criterion, we proceed to derive the optimum clipping threshold. Provided Monte-Carlo simulation results prove that our proposed approach outperforms the conventional singlestage clipping applied to NOMA and that the proposed optimum threshold significantly reduces the detrimental effects of impulsive noise in OFDM-NOMA systems where a gain of at least 10dB compared to the conventional clipping approach case is achieved by the successive interference cancellation (SIC) user.","PeriodicalId":354985,"journal":{"name":"2021 4th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114947964","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}

Their importance becomes a requirement in highly mobile and volatile environments, such as vehicular ad-hoc networks (VANET). In the present work, we propose a dynamic and decentralized reputation system that fits VANET characteristics like dynamism and volatility without conceding on security. The novel system uses blockchain for reputation information aggregation and storage and secure multiparty computation (SMC) to achieve privacy. Unlike previous VANET reputation systems, our system does not rely on a central authority to evaluate trustworthiness. Instead, it limits its role to maintaining the blockchain and system integrity leaving reputation evaluation to peers. It preserves feedback privacy in the presence of up to n − 2 dishonest parties and shows good performance. Remarkably, our system takes advantage of the infrastructure of VANET when vehicles are nearby while remaining fully functional in extra-urban areas.","PeriodicalId":354985,"journal":{"name":"2021 4th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116087945","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}

To that end, simple analytic expressions are derived for the above performance measures, which are subsequently employed in analyzing the corresponding effects of generalized multipath fading and shadowing in different realistic scenarios. This leads to insights that can be useful in the practical design of emerging wireless set ups as it is shown that the severity of composite fading is significant also in the context of channel capacity.

In this paper, the joint effect of both IQI and RHI on the secrecy outage probability (SOP) of a WCS subject to Fox’s H-fading channel is investigated. Such a fading model generalizes most, if not all, of well-known fading and turbulence models. To this end, novel generalized closed-form expression is derived for the secrecy outage probability for all possible scenarios namely (i) Transmitter (Tx) only impaired, (ii) Receiver (Rx) only impaired, and (iii) both Tx and Rx are impaired. α−µ has been considered as a particular case of Fox’s H-fading distribution. The analytical derivations, revealed by simulation results, demonstrate that the RF impairments’ effects should be seriously taken into account in the design of secure next-generation wireless technologies. On the other hand, the numerical results show that the parameters of fading channels can be used as a key to mitigating the effects of RF impairments on the secrecy performance.","PeriodicalId":354985,"journal":{"name":"2021 4th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131083064","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}

However, extant literature does not provide clear guidance on the extent of dominance, if any, of autonomous vehicles in terms of accident avoidance. We consider ‘vision’ inputs in autonomous vehicles and compare their performance to that of human-driven vehicles based on recent accident data and show that current state-of-the-art of vision technology in automated vehicles are grossly insufficient for truly autonomous vehicles.
