The CNT-based phototransistor has been computationally assessed by solving self-consistently the Poisson solver including the photovoltage with the non-equilibrium Green’s function (NEGF) formalism in the ballistic limit. This quantum simulation approach is adopted to take into account the BTBT mechanisms on which the photosensing principle is based in the proposed nanodevice. The light-induced gate photovoltage is adopted as photosensing principle. It has been found that the BTBT CNTFET can exhibit subthermionic optical swing. In addition, high photosensitivity can be recorded in BTBT regime to low gate photovoltages induced by weak IR incident optical powers. The obtained results indicate that the proposed nanoscale CNT phototransistor operating in BTBT photosensing regime can serve the modern optoelectronics, which is in dire need for ultra-sensitive phototransistors with low detection limits.","PeriodicalId":211056,"journal":{"name":"2022 IEEE Workshop on Complexity in Engineering (COMPENG)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122102494","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 optimize network signaling and power consumption, control plane (CP) optimization was introduced. In Release 15, to support infrequent small data transmissions, Early Data Transmission (EDT) was also included, in which the data are sent during the random access procedure. Thus, this paper analyses the latency performance of the different NB-IoT optimizations for the CP. The study, carried out in a real device, has been performed for different packet sizes and coverage levels. Evaluation results show lower latencies for EDT, particularly with small packets, where a reduced transport block is used, being more efficient from a network point of view. Additionally, we verify that EDT, unlike Release 13 optimization, fulfills 3GPP latency requirement for extreme coverage.","PeriodicalId":211056,"journal":{"name":"2022 IEEE Workshop on Complexity in Engineering (COMPENG)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131200776","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}

On the other hand, trees by their nature are subject to external stresses, from decay and therefore collapse phenomena. In order to monitor the trees stability, numerous investigations are carried out concerning physiological and biomechanical aspects. Among these we find the controlled pulling test, an analysis that reproduces the wind action (in a static way) on the tree and studies the resistance to overturning, in particular with regard to root anchoring to the ground. The models applied within this analysis present an important gap: the behavior of the canopy of trees subject to the force of the wind. This undergoes a reconfiguration of the branching in order to reduce the drag force, with direct repercussions on the impact area, the canopy porosity and the frequency of oscillation. The study of reconfiguration is a complex analysis, in the literature there are few works in relation to the wide variability given by the age, the species, the position of the trees. This preliminary study aims to introduce a new survey technique based on the use of opportunity data. By exploiting the presence of many meteorological webcams and applying web scraping procedures, it is possible to acquire a lot of data all over the world regarding the behavior of the canopy during meteorological events, taking into account wind and precipitation. Meteorological data are combined with RGB processing of crown shooting. Framework proves the feasibility of a database developing able to collect the dynamic tree crown behavior. Database permits a high level deepening about on multiple variable affecting branching response to wind load, like rain, wind direction, prevalent wind, and temperature. The results obtained are preliminary, as some improvements are still needed from a processing point of view, such as the automatic procedure that determines the crown area. We believe that sharing this technique with the scientific community can create new development opportunities and thus allow a more effective stability analysis.","PeriodicalId":211056,"journal":{"name":"2022 IEEE Workshop on Complexity in Engineering (COMPENG)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126412750","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}

Many algorithms for Top-K HUI mining have been proposed. However, the principal issue with these algorithms is that they need to store potential top-k patterns in the memory anytime, and they request the minimum utility threshold to automatically rise when finding HUIs. Consequently, the performance of existing exact algorithms for Top-K HUIs mining tends to decrease when the database size and the number of distinct items in the databases rise. To address this issue, we suggest a Binary Particle Swarm Optimization (BPSO) based algorithm for mining Top-K HUIs effectively, namely TKO-BPSO (Top-K high utility itemset mining in One phase based on Binary Particle Swarm Optimization). The main idea of TKO-BPSO is not only to use a one-phase model and strategy Raising the threshold by the Utility of Candidates (RUC) to effectively increase the border thresholds for pruning the search space but also to adopt the sigmoid function in the updating process of the particles. This might significantly reduce the combinational problem in traditional HUIM when the database size and the number of distinct items in the databases rise. Consequently, its performance outperforms existing exact algorithms for mining Top-K HUIs because it efficiently overcomes the problem of the vast amount candidates. Substantial experiments conducted on publicly available several real and synthetic datasets show that the proposed algorithm has better results than existing state-of-the-art algorithms in terms of runtime, which can significantly reduce the combinational problem and memory usage.","PeriodicalId":211056,"journal":{"name":"2022 IEEE Workshop on Complexity in Engineering (COMPENG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129033775","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 topic of structural monitoring of a building is becoming more topical with time, and many buildings from the 1960s and 1970s are under observation. The current challenge is to monitor structures effectively and continuously, applying the meaning of preventive maintenance, a concept well developed in engineering disciplines. New technologies allow us to assess the impact of time, wear, and tear, which in the long term can challenge the safety of buildings by monitoring the natural vibrations of a building. However, traditional monitoring systems in the civil infrastructure sector have always been expensive and undervalued. Therefore, borrowing innovations from computer science, a sensor system based on the new paradigms of the Internet of Things (IoT) was developed to provide a valuable alternative to proven vibration monitoring systems. The proposed system consists of a microprocessor (Raspberry Pi) and a low-cost accelerometer for microelectromechanical systems (MEMS), this type of lower costs sensor allows for investment in the safety of structures. The architecture of the monitoring system and the visualization of the vibrational model and its operation mechanism are presented. The performance of the monitoring system and the data collected are then integrated with Deep Learning techniques to obtain possible future scenarios and forecasts practically to perform tests that are as close as possible to reality and thus be able to act with the necessary maintenance to prevent undesired structural effects.","PeriodicalId":211056,"journal":{"name":"2022 IEEE Workshop on Complexity in Engineering (COMPENG)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129239415","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}
