Due to the physical structure of nanofibers, i.e., radii in the range of nanometers and lengths in the range of millimeters, they can be treated as excellent linear antennas. The application of the nano-antenna is in the early stages of development. In current literature, a model for an infinitely long, finite conductivity carbon nanotube as an antenna can be found. Consider finite-length metal-coated nanofibers, which are relatively inexpensive to produce. This paper examines the feasibility and difficulties of implementing metal-coated nano-antennas. The analysis includes an exact formulation, well known as Hallen’s equation, which includes an exact kernel. In this paper, it accurately calculates current distribution along a nanowire antenna using the exact kernel. While doing so, the singularities present in it are analytically removed. Many such fibers are thought to construct a nanofiber mat, on which current distribution can be calculated. The result is important for the calculation of the power profile over the mat due to the electromagnetic effect in general. For a nanowire with a nanometer radius, the assumption holds true for the higher frequency ranges, including the terahertz frequency range. Finally, an implementation for simple transceiver systems using nanowire antennas has been introduced and tested to meet the requirements for terahertz frequency range applications.","PeriodicalId":326693,"journal":{"name":"2022 International Telecommunications Conference (ITC-Egypt)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122671461","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}

There is a saying “A picture is worth a thousand words.” Pertaining to Digital Video the saying is “a video represents a million of those words strung together”. A digital video’s core components are frames. Video summarization is the procedure of distilling an original video to build a short raw video that keeps the important stories/content without sacrificing too much information. In this paper, a proposed model is offered for enhancement of dynamic video summarization based on deep learning producing a video skimming summary by selecting keyframes that have importance score met the specification. The task of assigning importance scores to certain frames in a video is critical for summarization, but it is also tough. Proposed model assigns a probability to each video frame, indicating how important it is to be selected, and then selects frames based on the expected values, creating video summaries. Using InceptionV3, ResNet50 pretrained models, it early fuses two feature sets for object-based and place-based in order to predict importance scores. The performance of proposed model has been compared to state-of-the-art models on TVSum dataset. Experimental evaluation show that proposed model performs better in terms of F-score to assess the effectiveness of the proposed model.","PeriodicalId":326693,"journal":{"name":"2022 International Telecommunications Conference (ITC-Egypt)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114795984","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}

In the present era, human activity tracking, indoor localization, and healthcare systems are all developing rapidly. Researchers are able to find practical solutions in healthcare facilities that often need to locate humans with the growing affordability and power of Radio Frequency (RF) technology. RF is appealing to monitor human activities in an unobtrusive and remote manner. Channel State Information (CSI) can be used as a contactless method to identify and locate human activity indoors. This paper presents the results of an experiment utilizing Universal Software-Defined Radio Peripherals (USRP) to locate the location of activity. A single subject is observed performing sitting, standing, no activity and leaning forward in six different locations inside a room to collect CSI samples. Additional CSI is collected when the subject walks in both directions within the designated area. Three Machine Learning (ML) classification algorithms were used in the comparison: Random Forest, Extra Trees (ET), and Multilayer Perceptron (MLP). When compared to other ML algorithms, the ET classifier has the best performance, with an average of 95% accuracy.","PeriodicalId":326693,"journal":{"name":"2022 International Telecommunications Conference (ITC-Egypt)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130121586","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 design was introduced by inserting a circular slot on the top surface of a rectangular patch antenna and an E-shaped parasitic patch placed in the center of the circular slot. Also, a partial elliptical shape ground plane has been used to enhance the bandwidth of the antenna. The proposed antenna exhibits a dual ultra-wideband. The first band operates from 3.94 GHz to 19.6 GHz with 133.05% fractional bandwidth (FBW) covering (n80 and n77) sub-6 GHz 5G communication bands, the complete bandwidth of WiFi-5, WiFi-6, and both amateur radio and amateur satellite bands. While the second one operates from 20.82 GHz to 29.34 GHz with 33.97% FBW covering (n257, n258, n261) mm-wave 5G bands. The substrate material used in the proposed antenna is a low-cost FR4 substrate that has a relative permittivity of 4.4 and a dimension of 32 mm × 34 mm and 1.6 mm thickness. The obtained results of the proposed antenna have been simulated using HFSS software.","PeriodicalId":326693,"journal":{"name":"2022 International Telecommunications Conference (ITC-Egypt)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134381227","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}
