Moreover, specifically in the online news industry, using sensationalist and eye-catching headlines for click-baiting has become a common practice. Finding relevant information is becoming harder than ever before. A solution to overcome the challenge is by utilizing a news recommender system. In most of the news recommender systems, a certain number of data attributes is required to produce appropriate decisions. Unfortunately, this is not always the case, especially when users are not required to register to a news portal. In this case, valuable information that can be used to make decisions, such as users’ preferences, visit or reading histories, will not be available. Therefore, in this paper, we take advantage of the elementary descriptive attributes of news articles, namely titles and keywords. We compare how these attributes affect the decision results, namely the recommended related news. We collected news articles from a news portal, generated two sets of related news using different compositions of descriptive attributes, and compared them to the originally defined set. Our findings indicate that the combination of titles and keywords produces highly relevant news which achieved a mean rating value close to 3 (on a scale of 1 to 5). Whereas the original recommended related news only has a mean rating value around 1. The combination produces better results compared to the original recommended related news which is highly affected by news categories. Our findings also revealed that the presence of specific entities (such as a person, location) in the titles has a significant impact on the outcome. This work has a wide spectrum of potential applications in the future, for example for automatic news aggregation, combating spam, reading context understanding, and so on.","PeriodicalId":228482,"journal":{"name":"2020 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129327714","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 type of blockage is important to be analyzed since it could reduce the duration of communication between ground stations and satellites. The amount of physical blockage has been calculated by employing a Digital Surface Model (DSM) dataset. The DSM enables the calculation of elevation offset between a ground station to its surrounding natural and man-made objects. Based on the simulation, the accuracy of the proposed approach is capable of resulting in 93.1% of accuracy. Apart from quantifying the amount of physical blockage for a certain point, the proposed approach has also been applied to map the distribution of physical blockage on the entire study area, Biak Island, Indonesia. It is found that the generated map can be used for determining a suitable location for building a ground station site.","PeriodicalId":228482,"journal":{"name":"2020 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116997568","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}

Propagation characteristics in maritime environment is different from one in the land therefore needed to be studied more. One important aspect in maritime radio propagation is path loss caused by sea movement. Sea movement in the seas of Indonesia varies from smooth to rough according to Douglas sea scale. The rougher the sea movement, the severer the path loss that happens in radio propagation. In this paper, the effect of path loss to the performance of wireless communication in maritime environment is investigated.

The development of WLAN equipment's including antennas, power dividers, and filters has raced to deliver the device to be compact, lightweight and low-cost. In this paper, a power divider integrated with filtering process, named as filtering power divider (FPD), is developed for 5.8 GHz WLAN application.

The SIW-based BPF which is designed to work at the frequency of 5.8GHz designed to make the output as impedance matching network. The design was carried out using simulation software to investigate the effect of different parameters of filter to the filtering process as well as the output response of FPD. The characterization results show that the operating frequency, bandwidth response and isolation of the output ports of proposed FPD are 5.8GHz, 90MHz and 19dB, respectively.

D2D communication led to significant interference on mobile networks when sharing radio resources, and precise radio resource allocation requires algorithms to reduce interference. This study aims to evaluate the most optimal radio resource allocation algorithm of 5G D2D communication underlying on a 4G LTE network using heuristic algorithms, minimum interference algorithms, and random allocation algorithms. Each algorithm tested with the scenario that involved variations of the cell radius distance, the value of data rate, fairness, and energy efficiency to determine the most optimal algorithm. The result shows that the higher amount of cell radius distance in a system makes the value of the system's data rate, fairness, and energy efficiency smaller because the gain on the device in the system also becomes smaller. Heuristic algorithms were having better data rates and energy efficiency compared to other algorithms. Therefore, it is suitable to be used when the level of system complexity is high. However, it works less optimally when a system has a vast cell radius because the heuristic algorithm's performance value tends to decrease with a more significant difference at each increase.","PeriodicalId":228482,"journal":{"name":"2020 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126760851","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 concept of antenna scattering decomposition into structural and reradiated scattered fields is used to ascertain the behavior of the radar cross section (RCS) of a metallic coplanar antenna structure with variable loadings. Then, a general analytical load condition that minimizes the bistastic radar cross section of the coplanar antenna structure is derived. The derived formula is used to obtain the regions of feasible passive loads for zero/minimum backscattering for the ultra-wide band (UWB) coplanar antenna. The backscattering minimization levels of this antenna is examined to validate the analytical formula. The results demonstrate the validity of the procedure with almost zero backscattering for the antenna with evident RCS reduction factors. Comparisons between the minimum RCS antenna with antennas of different loadings and with equivalent area metallic plates are presented.","PeriodicalId":228482,"journal":{"name":"2020 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125058310","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 super-resolution technique that received special attention recently is super-resolution based on deep learning. In this paper, we propose deep learning approach based on generative adversarial network (GAN) for remote sensing images super resolution. We used residual dense network (RDN) as generator network. Generally, deep learning with residual dense network (RDN) gives high performance on classical (objective) evaluation metrics meanwhile generative adversarial network (GAN) based approach shows a high perceptual quality. Experiment results show that combination of residual dense network generator with generative adversarial network training is found to be effective.

To improve the proposed antenna gain, a 3×3 array based on Electromagnetic Band Gap (EBG) metamaterials is implemented as a single planar array covering the radiating patch antenna. The proposed antenna is mounted on a FR4 substrate backed with a fully copper ground plane, and the radiating patch antenna is excited via SMA connector. The antenna is designed to operate at 5.8 GHz to match the WLAN and WiMAX applications. The microstrip antenna is loaded with Semi-H shaped unit cells of EBG structures. The antenna performance before and after adding the EBG structure is investigated in terms of reflection coefficient ($11), radiation pattern, bandwidth, aperture efficiency, and boresight gain. The antenna based on EBG structure is provided boresight gain enhancement from 1.8 dBi to 11.4 dBi for the frequency of interest. Since the introduction of the EBG structure with the conventional square patch antenna the proposed antenna has been achieved another achievement by enhancing the aperture efficiency from 3.2% to 29.6% and increase the bandwidth by 85 MHz and improving the Half Power Beam Width (HPBW) from 112° to 34° and 136° to 66° along the elevation (θ) and azimuth directions (φ), respectively","PeriodicalId":228482,"journal":{"name":"2020 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126248495","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}
