Therefore, it is very challenging to find the best nodes for carrying and forwarding messages, efficient disseminate messages in the network, as well as to have known and long-lasting routes. Furthermore, the traffic environment is exposed to various traffic densities and congestions, surrounding environment full of obstacles and unpredicted situations. Therefore, this paper presents an overview of bio-inspired routing protocols and methods that are handling all the abovementioned issues efficiently by applying various approaches such as clustering, using hybrid or MANET protocols, or merging two bio-inspired routing protocols.","PeriodicalId":284895,"journal":{"name":"2020 International Conference on Smart Systems and Technologies (SST)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131511358","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 achieve this, remote monitoring of animal activity with the aid of inertial sensors and use of machine learning algorithms over the collected data can be used. However, these algorithms rely on handcrafted features extracted by statistical or heuristic functions over raw motion data. To this purpose, we employ deep Convolutional Neural Networks (ConvNets) for activity recognition of livestock animals, such as goats and horses. We investigate the potential gains of ConvNets compared with other machine learning algorithms of the literature, which are about 12.5% greater accuracy and more than 7% higher F1-score. Moreover, we designate the advantages of late sensor fusion (2D convolution) and also show that an increase on the number of filters on each layer does not necessarily lead to a greater classification accuracy. To this end, we benchmark various ConvNet architectures and demonstrate the role of hyperparameter tuning to optimize the overall accuracy. To the best of our knowledge, ConvNets are employed for animal activity recognition here for the first time.","PeriodicalId":284895,"journal":{"name":"2020 International Conference on Smart Systems and Technologies (SST)","volume":" 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114051150","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 structure of the forecasting model includes three main components: trend, a seasonal and an irregular component.

Also, the attenuation calculation was made using simulated values of S11 and S21 parameters. These two sets of computationally derived data were compared with each other, and the differences were not significant. The values of EM wave attenuation during propagation through concrete were compared with the values from the available literature and the deviations are also minor. 5G systems use higher frequencies and the tested concrete materials shield the 5G signals better than 4G signals. The results of this research can be used in the building walls with high attenuation for 4G and 5G communication systems.","PeriodicalId":284895,"journal":{"name":"2020 International Conference on Smart Systems and Technologies (SST)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117334982","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}

Development of ADAS algorithms requires vast amounts of reliable data which accurately represents information available to the vehicle during its operation. Usually, cameras operate and capture everything only while ADAS is operational, meaning that all captured data is only used by the ADAS, and not preserved for later analysis. Storing all recorded information for future use in development of ADAS algorithms presents a significant issue and is the main motivation behind this work. This paper introduces a system capable of simultaneous video recording from up to 9 cameras on an external PC using PCI Express and reproduction of stored video materials using up to 9 output ports. The system connects to the cameras in vehicle and can be easily detached, thus allowing it to be moved to an algorithm development facility, where it can reproduce all recorded data. Using the developed system application, user can easily record selective data from the vehicle and then reproduce it in a development facility without any risk of information loss. System application also supports test pattern mode and frame extraction functionalities along with several tools for easier system configuration.","PeriodicalId":284895,"journal":{"name":"2020 International Conference on Smart Systems and Technologies (SST)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133152436","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}
