This work concerns FSO links’ availability estimation by taking into account both, the propagation into a dispersive media and the time jitter influence. Particularly, the truncated normal distribution has been used in order to investigate the time jitter effect on chirped longitudinal Gaussian pulses. The links’ performance is presented in terms of either probability of fade or outage probability, in closed form mathematical expressions. The work is concluded with the corresponding numerical results and inferences, using typical and realistic parameters of operating FSO systems.","PeriodicalId":122414,"journal":{"name":"2022 11th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128864235","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}

A new one-dimensional piecewise chaotic map based on the z-shaped fuzzy number is proposed and investigated, exhibiting regions of constant chaos and high Lyapunov exponent values. A pseudorandom bit generator based on the novel chaotic map is designed and successfully passes the National Institute of Standards and Technology (NIST) statistical tests. This PRBG is applied to the problem of image encryption, introducing a new image encryption scheme by using row and column permutation, chaotic pixel shuffling, and the exclusive OR operation. To demonstrate the robustness of this image encryption technique, various tests, such as differential attack and correlation, entropy and histogram analysis are performed.","PeriodicalId":122414,"journal":{"name":"2022 11th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123059020","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 tendency is called Smart Farming and promises to boost productivity while reducing production costs and chemical inputs. Cloud Computing aims to provide the necessary resources and the central orchestration of all devices involved in a Smart Farming scenario. To achieve high scalability, usability and performance in Cloud-based applications, we have to move from a monolithic development approach to microservices architecture using cutting edge technologies like containerisation. This paper presents a Smart Farming application based on Cloud Computing that promises to provide useful information to agronomists and farmers to support their decisions based on measurements from ground sensors and images captured from UAVs or ground cameras. Our implementation is based on microservices architecture using Docker Containers as the virtualisation technology. Each microservice runs on a different container and communicates through a RESTful API interface. The proposed architecture is highly scalable in future upgrades and promises high performance and security.","PeriodicalId":122414,"journal":{"name":"2022 11th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127304013","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 has been experimentally observed that this memristor, under certain conditions, can behave as a static nonlinear resistor. This inherent property of the KNOWM’s memristor prompts its use as a nonlinear reistor in chaotic circuits. Therefore, in this work, for the first time, the KNOWM memristor is used as a static nonlinear resistor in a well-known chaotic oscillator circuit. In order to examine circuit’s dynamical behavior a host of nonlinear simulation tools, such as phase portraits, bifurcation and continuation diagrams, as well as maximal Lyapunov exponent diagram, are used. Interesting phenomena related to chaos theory are observed. More specifically, period-doubling route to chaos, crisis phenomena, antimonotonicity, hysteresis and coexisting attractors, are investigated.","PeriodicalId":122414,"journal":{"name":"2022 11th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124396721","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 positioning methods have been evaluated including wireless communications and inertial navigation systems. In particular, UWB systems, with improved stability and precision, that have been developed in recent years pose a good solution for IPS. Although UWB technology provides with great accuracy in Line-Of-Sight (LOS) conditions, it suffers in Non-Line-Of-Sight (NLOS) conditions. Accuracy is also degraded due to signal interference caused by the multipath effect. In this paper a UWB-based localization system is under test in order to evaluate the efficiency of the measurements. A set of position data was acquired in lab environment. Simple filters, in means of computational power, were applied, and the results are compared with the true path.

In ReRAM arrays that consist of two-terminal bipolar resistive switching (RS) devices, SET/RESET programming voltage pulses are used to switch them from low resistance state (LRS) to high resistance state (HRS). The recent commercialization of discrete and crossbar-array organized RS devices have certainly pushed forward experimentation with such emerging memory technology. One barrier still preventing their widespread practical use is the behavioral variability and the lack of a straightforward manner to implement the forming process and achieve uniform SET/RESET programing. In this paper, different circuit topologies and approaches are explored to perform the forming of the conductive channel in commercial discrete RS devices by Knowm Inc. A target-resistance is pursued through pulsed voltage stress, followed by cycle-to-cycle stabilization using a custom transimpedance amplifier circuit. Moreover, a voltage controlled low–current source is proposed as an approach to alleviate the complexity and risk of the forming process in device characterization.","PeriodicalId":122414,"journal":{"name":"2022 11th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133886838","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}
