This paper proposes compact triple-band Y-shaped microstrip patch antennas (MPAs) for 5G applications. The proposed antenna has a dimension of $5 times 5 times 0.381$ mm3, uses Rogers/ RT Duroid 5870 as a substrate material, and a loss tangent of 0.0012. The Defected ground structure (DGS) in the middle and groove at the top of the ground plane was implemented. This achieves -10 dB bandwidth from 29.55-30.72 GHz with a maximum gain of 6.834 dB, from 57.36-63.34 GHz with a maximum gain of 10.196 dB, and from 68.56-94.281 GHz with a maximum gain of 8.628 dB at resonant frequencies 30.1 GHz, 60 GHz, and 81.3 GHz respectively. The proposed antenna has a high gain and a broad bandwidth making it a candidate for 5G millimeter-wave (mmwave) applications. Higher Frequency Structural Simulator (HFSS v13) tool is used to simulate the proposed antenna.","PeriodicalId":334654,"journal":{"name":"2021 International Conference of Technology, Science and Administration (ICTSA)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117154594","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 automatic generation of buildings from satellite images presents a considerable challenge due to the complexity of building shapes. Compared with the traditional building extraction approaches, deep learning networks have shown outstanding performance in this task by using both high-level and low-level feature maps. Recently, many deep networks derived from U-Net has been extensively used in various buildings segmentation tasks. However, in most of the cases, U-net produce coarse and non-smooth segmentations with lots of discontinuities. To improve and refine the performance of U-Net network, we propose a deep end-to-end network, which use a single encoder and two parallel decoders along with performing the mask predictions also perform distance map estimation. The distance map aid in ensuring smoothness in the segmentation predictions. We also propose a new joint loss function for the proposed architecture. Experimental results based on public international society for photogrammetry and remote sensing (ISPRS) datasets with only (RGB) images demonstrated that the proposed framework can significantly improve the quality of building segmentation.","PeriodicalId":334654,"journal":{"name":"2021 International Conference of Technology, Science and Administration (ICTSA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121872213","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}

It is caused by fluid imbalance within the eye that leads to increase in intraocular pressure (IOP), and therefore a damage to the optic nerve head (ONH) which is responsible in transmitting visual neurological signals to the brain. Traditional methods for detecting Glaucoma disease either tedious and slow or too expensive. Hence, early detection of Glaucoma is essential to avoid permanent blindness which might be caused by the ONH failure. In this paper, an automated detection method on the basis of pre-trained Convolutional Neural Network (CNN) models is proposed to detect Glaucoma from fundus images. The proposed method not only contributes to early detection of Glaucoma disease, but also helps optometry doctors in making fast decision with inexpensive tools. Pre-trained AlexNet, VGG11, VGG16, VGG19, GoogleNet (Inception V1), ResNET-18, ResNET-50, ResNET-101 and ResNet-152 models were leveraged to develop the proposed Glaucoma detection method. The proposed method was evaluated by Large-scale Attention based Glaucoma (LAG) dataset. Satisfying results of 81.4%, 80%, 82.2%, 80.9%, 82.9%, 86.7%, 85.6%, 86.2%, and 86.9% were observed on LAG dataset using AlexNet, VGG11, VGG16, VGG19, GoogleNet (Inception V1), ResNET-18, ResNET-50, ResNET-101 and ResNet-152 models respectively.

The traditional user association approach is inefficient for HetNets due to the high transmission power of macro base stations (BSs) and the low transmission power of small cell BSs, i.e., pico and femto BSs. This approach causes macro BSs to be overloaded whereas small cell BSs are lightly loaded. To address this load imbalance in 5G HetNets, 3GPP introduced the concept of cell range expansion (CRE) where the coverage area of small cell BSs is artificially increased by adding a bias value to the power received from small cells. Although the biasing approach can better balance the load among tiers, users at the expansion area suffer from severe interference coming from neighbouring macro BSs. This work utilizes coordinated multi-point transmission (CoMP) to reduce interference. User-centric clustering where a user can be served by a number of BSs is implemented. The results have sown that user-centric CoMP can significantly improve the SINR levels of all users and cell-edge users as well.","PeriodicalId":334654,"journal":{"name":"2021 International Conference of Technology, Science and Administration (ICTSA)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128954275","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 makes it difficult to introduce schedule-building restrictions that consume time and effort for table production. Many methods have been suggested that the computer is used to solve this problem, including a Genetic Algorithm (GA) where the main purpose of the algorithm is to reduce the number of conflicts in the timesheet and to reduce the search space encoding. This paper proposes an automated system to build a faculty timetable using a genetic algorithm. A genetic algorithm had been used to schedule the timetable of the faculty of engineering and information technology with a dynamic chromosome size that is flexible with the course numbers of each department. This algorithm can be applied in different institutions (i.e. faculties, or institutes) According to their limitations. The proposed system achieved great results during the evaluation phase of around 93% compared to manual scheduling or the systems available.","PeriodicalId":334654,"journal":{"name":"2021 International Conference of Technology, Science and Administration (ICTSA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121111593","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 performance of the optical network is directly related to the type of optical switching technique used. Optical burst switch (OBS) is currently being developed as a technology capable of supporting wide bandwidth, enabling high transmission of information and various types of traffic. Losses due to contention between bursts at the core nodes are one of the main problems that prevent the achievement of optical burst switching (OBS) technology on core networks. In this paper, wavelength conversion and deflection routing techniques used together to get the best solution for the problem of contention bursts that might be occurred at the core node.
