Due to the increase in the number of recursive Riccati-type algebraic equations, the accumulation of round-off errors is not negligible. The round-off errors cause unstable numerical characteristics of the filter, especially for the small variance of the observation noise. To reduce the round-off errors as the first attempt in the research field of centralized robust multi-sensor estimation this paper designs the Chandrasekhar-type centralized robust multi-sensor RLS Wiener filter, which updates the filter gains recursively. To verify the effectiveness of the proposed filter, a numerical simulation example is demonstrated and its estimation accuracy is compared with the centralized robust multi-sensor RLS Wiener filter and the centralized multi-sensor RLS-Wiener filter. The obtained results show that the proposed filter exhibits better stability.

Unfortunately, due to the large amount of information on social networks as well as the anonymity of users, it is very difficult to identify and detect these crimes; so it is necessary to provide automatic tools to search and report criminals on these networks. So far, several methods are introduced with the capability of automatically detecting criminals. However, all of these methods require access to content published by the users. In this paper, a new method is proposed. It is capable of identifying criminals in social networks based not on their published content but only on their social relationships. The proposed method is based on the assumption that criminals, indirectly, have strong connections with each other. It includes two algorithms, the first algorithm is utilized for crawling the social network, and the second algorithm for detecting criminal users among the users collected in the first phase. Having an initial set of criminals, the method first crawls the network starting from this set. The crawler is configured to collect users who are more likely to be criminals. Then, these users and their relationships form a graph, and users are ranked based on five centrality measures (namely degree, betweenness, closeness, hubs and authority centralities) that have a strong correlation with the likelihood of users being criminals. The obtained results show that the proposed method can well identify criminals and rank them. The degree and closeness centralities showed the best results while betweenness centrality showed the worst results. For instances, the closeness centrality has been able to correctly identify criminals with 90% accuracy.","PeriodicalId":29729,"journal":{"name":"Jordan Journal of Electrical Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70821824","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 proposed system’s primary use is to assist a user with a physical disability in painting on canvas. Gaze estimation is administered using only a webcam through a unique combination of object detection algorithms, like Haar cascades, to localize facial features and learned linear regression models to translate facial features to gaze location. The custom GUI allows a user to draw a line or a circle in four different paint colors on a virtual canvas before committing their shape to a physical canvas solely through using the lowaccuracy webcam-based gaze estimation. The system and its prototype are found to have utility through basic acceptance and system testing, but the chosen gaze estimation solution is generally too low accuracy for a positive user experience.

Using the classical vector potential approach, the paper rigorously formulates radiation-zone field integrals for the antenna in terms of an unknown distribution of current. Because the formulation derives from a comprehensive analytical description of this ‘log-helix’ antenna’s geometry, the unknown current distribution is readily determined with the use of the circuitgeometric properties of the Method of Moments (MoM). Subsequently, computational results reveal that as obtained with other non-uniform helical antennas the ‘log-helix’ antenna performs significantly better than the corresponding uniform helical antenna of identical axial length. As examples, a 39% increase in power gain was recorded for the log-helix over the corresponding uniform helix; whilst a 25% improvement in radiation field’s axial ratio was achieved. In addition to far-zone fields and their associated performance metrics, antenna input parameters are also computed and discussed in details in this paper. Outcomes of a comparison of the performance of the log-helix with that of an exponential helix of about the same axial profile suggest that whereas the latter has a better power gain performance, the former is superior in terms of axial ratio bandwidth performance.","PeriodicalId":29729,"journal":{"name":"Jordan Journal of Electrical Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70821702","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}
