Nevertheless, the operation of these systems is strongly affected on weather conditions and especially by atmospheric turbulence. In order to counterbalance the negative effects of turbulence for a given propagation distance several techniques have been proposed in the literature. One of the most well-known and effective among them is the receivers’ diversity. Motivated by this, in this work, the influence of the modulation scheme in the total average block error rate of a single input multiple output (SIMO) free space optical (FSO) system over strong turbulent channels is estimated and new closed form analytical expressions are derived.","PeriodicalId":146990,"journal":{"name":"2021 10th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122348233","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}

All methods are studied under the premise of utilization in a Time-Difference-Of-Arrival (TDOA) approach for the signal’s speed estimation, that leverages the expected time delay in the signal’s pickup by consecutively installed sensors, due to the travel time spent as the acoustic signal spreads along the examined pipeline. Two popular, frequency domain cross-correlators are investigated, namely the Phase Transform (PHAT) and the Hassab-Boucher (HB), along with the baseline time domain cross-correlation algorithm. An inventory of acoustic data - captured by a vibration monitoring rig during a series of leak signal data gathering experiments, conducted on an existing pipeline installation - is utilized for the investigation of the performance of each method and the illustration of the comparative results. The far-reaching target of the ongoing study, that encompasses the current work, is to derive a cross-correlation based, acoustic method for leakage localization on metallic pipelines carrying hydrocarbon products.","PeriodicalId":146990,"journal":{"name":"2021 10th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122624723","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}

Several such applications rely on the use of dense passive crossbar arrays, which are now becoming commercially available and accessible to researchers. However, experimental measurements on crossbar arrays not only require special caution but also special driving techniques, both for reading and writing of data, while addressing the current sneak-paths problem. This makes highly relevant the development of instrumentation solutions that provide a safe and proper way to experimental work with passive memristive crossbars. In this direction, we present our early design steps towards the development of an instrumentation printed circuit board (PCB) which addresses the characterization and testing of memristive crossbar chips. The PCB will be interfaced through a STM32 microcontroller system and has a PCI socket compatible with crossbar chips sold by Knowm Inc. We present the driving circuitry in detail and LTspice circuit simulation results that verify/quantify the performance of reading/writing processes.","PeriodicalId":146990,"journal":{"name":"2021 10th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114268594","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, the application of convolutional models encounters some challenges to deal with such as (i) the requirement of a vast amount of training data and (ii) the selection of the neural architecture, and particularly the sizes of the convolutional kernels that effectively extract features from the raw input signal. To alleviate the above challenges, we propose a deep learning network consisting of multiple independent densely connected convolutional streams with different sizes of kernels and of a simple attention mechanism that fuses the extracted features, producing a feature mapping with generalization and discrimination power. Simulation cases with a widely used bearing fault detection benchmark show the effectiveness of the proposed approach, especially in cases of a restricted amount of training samples.","PeriodicalId":146990,"journal":{"name":"2021 10th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129673526","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 prototype has been deployed in a vineyard in Peta village, Greece, as part of the AREThOU5A project. An IoT framework for regularly and accurately tracking the status of soil hydration and reporting it to a centralized entity for further processing since water needs are directly related to soil moisture is proposed. The framework is based on specialized IoT hardware that includes low-cost microcontrollers with integrated sensor interfaces and telecommunication modems, open-source applications, open and standardized data transfer protocols, with low capital and operating costs. In the vineyard, an IoT end-node have been placed. Each node: i) collects soil moisture and temperature samples at a depth of 20 cm, ii) is battery-powered and has a battery life of several months on a single charge, and iii) connects to the system back-end via NB-IoT. The sensor measurements from the IoT nodes are forwarded to a cloud-based infrastructure using the Constrained Application Protocol (CoAP)/IPv6 protocol using a public mobile network. Data is maintained on a cloud backend and can be accessed in real-time via dashboards from any Internet-connected individual. In terms of hardware integration, operating solutions, networking and connectivity support, the proposed platform offers numerous novel features.","PeriodicalId":146990,"journal":{"name":"2021 10th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128165063","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}

Variations due to coupling are compared with variations due to temperature, showing that both effects may result in a readout error of the same order of magnitude for the top-tier readout circuit. Nevertheless, we demonstrate that in a typical rolling readout, the sequence of the pixel control signals makes the coupling effect nearly negligible. As a result, we suggest that the fabrication of an inter-tier ground plane for electrical isolation is not strictly necessary for Monolithic 3D pixels when the readout top tier is directly stacked on the photodiode bottom tier.","PeriodicalId":146990,"journal":{"name":"2021 10th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"670 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132333332","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}
