Considering the fast development in metaheuristics, choosing the most appropriate algorithm to solve this problem is a difficult task.

On the one hand, a report published by the WHO estimated that some 1.3 million people are killed and 50 million injured in road accidents worldwide each year. On the other hand, a report published by the National Observatory of Road Safety in Tunisia showed that 1007 people were killed and 6757 injured in Tunisia in 202. Certainly, the statistics allow estimating the level of road insecurity at the global and national levels. To improve the current situation of road safety in Tunisia we propose a new mobile crowdsourcing platform called R-safety which allows road users to report in real-time their road safety feeling indexes. It also allows users to report violations they witness and interact with the NORS. R-safety also aims to inform citizens about risk areas through a vulnerability map that divides the areas into five types from the least dangerous to the most dangerous. In our approach, we are interested in improving the current situation of road safety by integrating the opinions of road users in the decision support tool of the national observatory of road safety. Thus, integrating citizens opinions into the information system would serve to have new sources of incoming data to improve decisions. This research work responds to real needs discussed with the members responsible for the studies and research of the NORS. We are evaluating our proposal through a questionnaire with 524 participants. This questionnaire helps us to choose among the proposed safety indicators those that affect road safety according to the citizen's opinion. This result confirms the importance of our crowdsourcing service.","PeriodicalId":185510,"journal":{"name":"2022 8th International Conference on Control, Decision and Information Technologies (CoDIT)","volume":"494 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133153340","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 can extract only 5% of the information held in the signal. Computer-assisted diagnosis could offer a way to obtain fast and reliable results and significantly reduce inter-and intra-assessor variability. In this document, we will present a tool for automatic analysis of EEG based on artificial neural networks. The proposed method consists in using signal processing and artificial intelligence algorithms to improve the interpretation of the EEG. For this purpose, we have two databases from the Nihon Kohden and Cadwell systems whose files are encrypted. The first step was to develop an application to decrypt and read the files. Thanks to this, the files could be decrypted in a standard format and the signals could be read. After that, we applied our method of automatic interpretation of the EEG. First, we preprocessed the signals using an Notch filter (50 Hz) and a bandpass filter (1–30Hz). Then, we extracted the features in the time-frequency domain based on three elements: the wavelet transform, its means, and its standard deviations. These features represent what we have used as inputs to our neural networks for classification. Our algorithm efficiently interpreted EEG signals with a correct classification rate of 97.9%, a sensitivity of 96.9%, and a specificity of 98.9%. These results have been deployed in an application that allows not only to visualize automatically the signals and the power spectral densities but also to extract the characteristics while displaying the wavelet transform related to the EEG signals of each chain.","PeriodicalId":185510,"journal":{"name":"2022 8th International Conference on Control, Decision and Information Technologies (CoDIT)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133439947","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 BLF imposes partial constraints to keep the trajectories of the system inside a safe operation set. The proposed controller is tested in a virtual one-link robotic manipulator including actuator dynamics to develop an adequate trajectory tracking.

The main drawback of numerous approaches lead to small or limited sampled time period, which is an important point in industrial processes. To overcome this difficulty, we propose a modified inter-sampled observer-predictor which ensures an exponential convergence and gives the ability to push the sampled time period to its limit. Comparing to other observer structures, our design is char-acterized by its simplicity because we only need a tuning gain. Our main contribution is to show that our modified observer allows to widen the sampling period as much as possible, while guaranteeing the exponential convergence of our observer. The effectiveness of our proposed approach is shown through numerical simulations which have been performed on a well-known bioreactor example.","PeriodicalId":185510,"journal":{"name":"2022 8th International Conference on Control, Decision and Information Technologies (CoDIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122981864","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 system consists of a FCS and a power boost converter that delivers energy to a load despite input voltage variations and significant load changes.
