Here, we simulated two hexarotors: a fully-actuated one that maintains level its attitude, and therefore that of the visual sensors; and an under-actuated one. Both vehicles were meant to fly forwards in a tunnel while reacting to the irregularities of the terrain, adopting a bee-like behavior based on a nonlinear optic flow regulation. The dynamic models are provided by means of the Newton-Euler equations, nonetheless, the unit quaternion representation is used for a suitable treatment of the rotational motion. The attitude stabilization depends on the knowledge of the quaternion itself, moreover, and due to the non-linearities related to the translational optic flows, visual guidance relies on the implementation of adaptive integral sliding mode controllers to accomplish a triple direct regulation (forward, side and lift commands). We compared both vehicles performance using detailed numerical simulations, validating the concept that a fully actuated hexarotor permits to improve the optic flow based navigation task.","PeriodicalId":220845,"journal":{"name":"2022 26th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117158091","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 control solution to this problem includes two functionalities: the hardware level of operation, detection, and communication, and the second level, software, which consists of advanced surveillance algorithms for the environment and the implementation of control algorithms. This paper aims to develop and implement an algorithm to compute the maximum velocity of a vehicle on a certain road sector. Linear mathematical models describing the operation of the vehicle were used emphasizing the two dynamics, longitudinal and lateral, respectively. The velocity adjustment solution is based on the model predictive control strategy that ensures good performances. As a reference to the process, several types of trajectories were considered based on which it was possible to calculate the velocity at each point. In this way, the velocity has been adapted accordingly, taking the maximum value necessary to achieve a safe movement along the road.","PeriodicalId":220845,"journal":{"name":"2022 26th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"439 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122122969","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 model is obtained as a special case from a rather general hydroelectric plant structure with distributed parameters of the water flow along the conduits. The stability of the linearized model is discussed using the stability of an associated system of neutral functional differential equations via the classical results on Hurwitz quasi-polynomials obtained by N.

The prevention methods applied standardized to the female population contribute to the reduction of incidence and mortality. Medical approaches include colposcopy, a way of visual inspection of the cervix, and identification of cervical, benign or malignant lesions. Being an analysis that depends entirely on the expertise of the medical professional who performs it, it can be improved by artificial methods. Deep learning has been successfully applied in the field of medical imaging and also in the classification of cervical lesions. In the presented paper, a set of convolutional networks for deep learning was used, consisting of a network with residues and a dense network, pre-trained on an extensive database and applied to a limited dataset. The assembly achieved accuracy on the validation set of 69%, improving the performance of individual models by 2 and 4 percent, respectively. The presented approach classifies 5 types of cervical lesions, the novelty lies in the extensive number of categories, since the literature addresses a more limited number.","PeriodicalId":220845,"journal":{"name":"2022 26th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129884655","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 observability analysis is performed based on the existence of canonical forms, which is the most employed method for bioprocesses and the results are interpreted based on the condition number of the observability matrix. Two state observers are implemented, an Extended Kalman Filter and a High Gain Observer, to reconstruct the full system state from the available measurements. Simulation results are presented for two scenarios: i) biomass, glucose and ethanol concentrations are measured; ii) only biomass concentration is measured. Only for the first scenario uniform observability could be established with the employed method. Nevertheless, in both scenarios, similar estimates of all system states were provided by both observers.","PeriodicalId":220845,"journal":{"name":"2022 26th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129655518","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 approach presented here is based on modeling public spaces as graphs and adding weights corresponding to the potential difficulty to cross their edges. The typical path generation algorithm is extended to deliver the right guidance to pedestrians with mobility problems. By selecting a policy specific to their needs in the routing application, the users can have details on how hard it is to access a certain location of the public space.

Our goal is to introduce a new method for measuring the sensitivity of deep neural networks doing semantic segmentation and thus determine how stable these networks are when image alterations are encountered during real life image capturing. To achieve our goal, we construct a sensitivity analysis model and apply it to some commonly used semantic segmentation CNN architectures (PSPNet, ICNet, DeepLabV3) across a couple types of image degradations. Extrapolating the results we obtain would allow for estimating various CNN models performance for new domains comprised by images of lower quality (captured with different types of camera or light conditions). Our specific experiments for semantic segmentation task revealed that DeepLabV3is more stable to input image degradations than PSPNet and ICNet. However, for some object classes even DeepLabV3is seriously affected by the input noise.","PeriodicalId":220845,"journal":{"name":"2022 26th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126849016","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}

Therefore, it will also interconnect billions of smart devices autonomously, while ensuring security, coverage, and reliability. The scope of this paper is to analyze the effect of communication distance for 5G networks. Specifically, we evaluated the performance of 5G communication between an user equipment (UE) and a 5G base station (gNb) in a dense urban area from the city of Iasi, Romania, which are at different distances from each other, such as 100 m, 200 m, 300 m, and 400 m. A practical approach was chosen to perform the measurements, using SIM8200EA-M2 module for the communication with gNB. In order to see how distance can affect the performance of the 5G network, a number of performance indicators relevant to 5G communication were analyzed, such as Reference Signal Received Power (RSRP), Signal to Interference Noise Ratio (SINR), and jitter. As expected, the results illustrate a decrease of 5G performances with an increase of the distance between the UE and the gNB.","PeriodicalId":220845,"journal":{"name":"2022 26th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114201758","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}

At the same time, more sustainable vehicles are required. This causes the necessity to integrate new software and hardware products in an existing vehicle. Additionally, a rising variety of electric comfort elements increases the complexity of the automotive power network (APN). In order to address these challenges, we propose a modular and flexible power network management based on auction theory for modern vehicular architectures. The approach facilitates the effortless integration of new components in the APN. Furthermore, by the combination with a service-oriented architecture (SOA) communication paradigm, the algorithm is safe for a single electronic control unit failure. In this contribution, we elaborate the SOA communication within the load management and define a procedure to handle switching loads. The effectiveness of the approach is demonstrated with simulations considering an exemplary APN with constraints in the power electronics.","PeriodicalId":220845,"journal":{"name":"2022 26th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115830024","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}
