For this reason, they need to be equipped with a whole arsenal of tools which can assist their senses during field operations. To augment FRs’ vision, in this work we employ a commercially available Ultra WideBand (UWB) radar sensor for the purposes of victim detection behind large obstacles, such as walls and doors. In particular, we have created and present here a dataset, which incorporates about 15 hours of data records, for a number of different scenarios. This dataset has been uploaded in an openly accessible database to give the opportunity to the research community to apply and further develop methods for human detection behind large obstacles. Finally, we introduce a novel and of low complexity method which is applied in the collected dataset managing to attain a more than 95% accuracy in victim detection.","PeriodicalId":126970,"journal":{"name":"2023 12th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124407335","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 Pattern Recognition Mezzanine (PRM), part of the Hardware Tracking for the Trigger system, is one of the boards where track fitting and track reconstruction is being performed using linearized algorithms in an Intel Stratix 10MX FPGA. The input of the the PRM is clustered data. Given the clustered information, the PRM FPGA encodes Superstrip IDs (SSIDs). The SSIDs are a coarser representation of the clustered information which is used for the pattern recognition. Before being further processed by the PRM, the clustered data are sorted per their SSID. A scalable sorting algorithm has been implemented for the fast sorting, taking advantage of the FPGA architecture allowing adjustments for achieving balance between resource utilization and performance. This paper summarises the PRM board, its firmware design and its challenges. It focuses on the data preparation step, discusses its implementation and reports on tests done with simulated data.","PeriodicalId":126970,"journal":{"name":"2023 12th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"05 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124473294","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}

An increased performance is expected which, theoretically, can be expressed as a double increase in system throughput. However, due to the initial design of the basic access method in WLANs, known as Distributed Coordination Function (DCF), this performance boost is poorly exhibited. Game theory is an invaluable tool to model the performance of Medium Access Control (MAC) protocols used in WLANs. In this paper, we exploit game theory to propose a simple enhancement to the DCF access method, in order to increase the benefit received when the FD capability is enabled in ad-hoc WLANs.","PeriodicalId":126970,"journal":{"name":"2023 12th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125087703","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}

According to our simulation results, BTI aging can affect the computation reliability of IMC cells.

Therefore, its use has been limited to the trade-off between quality of the result and hardware cost in error-resilient applications. In this paper, we show that in addition to such a trade-off, it is possible to increase the system’s output quality, thanks to regularization that approximate processing introduces. Unlike the conventional noise injection techniques, approximate processing offers a strong correlation between the input signals and the output noise, which can be beneficial as a regulizer. We show using simulation results that the provided regularization by properly selected approximate adders in a source localization application not only improves the hardware efficiency, but also increase the regression accuracy in comparison with the exact implementation. Remarkably, these improvements are additional to a substantial decrease in the memory size as well as number of multiply-accumulate units of our proposed model in comparison to a state-of-the-art model in the literature.","PeriodicalId":126970,"journal":{"name":"2023 12th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127715473","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}

Similarly, research efforts in the field of RF engineering over the last few years have focused on replacing MEMS with memristive switches. These switches have been recently investigated, fabricated, and characterized, demonstrating promising operational characteristics under high-frequency stimuli. In this work, a widely employed memristor model has been used to accurately fit the physical characteristics of the devices under investigation, including geometry and material composition. Subsequently, three common circuit topologies are adopted, studied, and simulated to extract the S-Parameters of the memristor-based switches matched to 50Ω load terminations. Our findings ensure sufficient functionality of the examined memristor-based switches up to FMAX=50GHz and suggest promising perspectives, slightly exceeding the projected results in previous studies found in the literature. Finally, a method for further enhancing the proposed circuit, in terms of increasing the power handling capability of the designed switches, is also proposed.","PeriodicalId":126970,"journal":{"name":"2023 12th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128129802","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}
