Creating a model to detect freely moving fish underwater in real-time is a challenging process for two main reasons. First, the available datasets suffer from some limitations that severely affect the results of the detection models operating in challenging and blurry environments. These models should be able to capture all of the fish movement given different types of surroundings. Second, choosing the convenient detection model system which matches the desired requirements from having high accuracy with satisfying frames per second (FPS). To overcome the first challenge, a new dataset was created by extracting 1800 frames from videos and manually annotating them to overcome the different background issues and the complex movements and orientations of the fish. Regarding the second challenge and after comparing between different object detection systems, YOLOv3 was chosen as it proved to achieve high accuracy among other systems. The proposed approach scored 76.81% using (mean average precision) mAP as an accuracy metric and 89.17% using F-score, which is considered one of the most accurate outcomes among the literature. Moreover, the model rate is 12 FPS which is satisfying for real-time.

Topologies of power-law proportional-integral controllers, which offer minimization of the active component count are presented in this work. This is achieved thanks to the utilization of RC networks, which approximate driving-point impedances described by power-law functions. Additional important features of the presented schemes are their capability of achieving minimization of the spread of passive elements, as well as of implementing values of order greater than one.

For the sake of proper diagnosis and treatment, accurate brain tumour segmentation is required. Because manual brain tumour segmentation is a time-consuming, costly, and subjective task, effective automated approaches for this purpose are generally desired. However, because brain tumours vary greatly in terms of location, shape, and size, establishing automatic segmentation algorithms has remained challenging throughout the years. Automatic segmentation of brain tumour is the process of separating abnormal tissues from normal tissues, such as white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF). Brian segmentation needs typically to be carried out for different image modalities in order to reveal important metabolic and physiological information. These modalities include positron emission tomography (PET), computer tomography (CT) image and magnetic resonance image (MRI). Multimodal imaging techniques (such as PET/CT and PET/MRI) that combine the information from multiple imaging modalities contribute more for accurate brain tumour segmentation. In this work, we introduce a deep learning framework for automated segmentation of 3D brain tumors that can save physicians time and provide an accurate reproducible solution for further tumor analysis and monitoring. In particular, a 3D U-Net was trained on brain MRI data obtained from the 2018 Brain tumor Image Segmentation (BraTS) challenge. Three optimizers (RMSProp, Adam and Nadam) and three loss functions (Dice loss, focal Tversky loss, Log-Cosh loss functions) were used. We demonstrated that some loss functions and optimizers combinations perform better than other ones. For example, using the Log-Cosh loss function along with RMSProp optimizer resulted in the highest Dice coefficient, 0.75. Indeed, we also optimized the network hyperparameters in order to enhance the segmentation outcomes. These results demonstrate the feasibility and effectiveness of the proposed deep learning scheme with optimized hyperparemeters and appropriate selection of the optimizer and loss function.

This paper outlines the design and the development of a novel robotic exoskeleton finger. The new exoskeleton mechanism aims to produce an efficient prototype with a trajectory similar to a natural finger. This novel design combines both the classical Bennett mechanism and a new mechanism named kinetiX. kinetiX was primarily introduced by MIT media lab at Massachusetts Institute of Technology (MIT). This exoskeleton finger is driven by a single actuator to ensure the actuation simplicity. In addition, it is characterized by its flexibility, lightweight and human-like slender shape. Therefore, it allows the smooth transmission of position and force to the tip of the finger. The design constraints of the new mechanism are deduced from the user biomechanics. The mechanical design of the device is proposed, manufactured and tested. It is shown that the new design is able to emulate the finger flexion/extension curvature movements successfully.

The active control of flow around an airfoil through morphing is numerically investigated. The lock-in phenomenon was predicted while using a fixed grid. Galerkin/Least-Squares Finite Element Method was used to simulate incompressible flow over an airfoil with leading edge morphing at a Reynolds number, $Re = 5000$, and angle of attack, $alpha = 6^{circ}$. The numerical simulation was carried out using the in-house FORTRAN code. The code was validated with the literature by simulating the flow over an oscillating cylinder. The paperwork implemented a locally oscillating surface on the airfoil with a deformation function. The non-dimensional oscillation frequency was varied in the range of [0.4 - 2.7] and the flow frequencies were analyzed. The primary and secondary frequencies were recorded at each simulation and the lock-in region is specified. The streamlines and vorticity contours are presented at two different excitation frequencies, specifically, $f_{e} = 1.0$ and $f_{e} = 2.5$. The streamlines and vorticity contours showed the formation of the vortices in both cases. The results show great accuracy for the Level-Set Method compared with the literature work that used the Arbitrary Lagrangian-Eulerian method, and the flow frequencies can be predicted accurately.

Novel Coronavirus Disease 2019 (COVID-19) is a new pandemic that appeared at the end of March 2019 in Wuhan city, China, which affected millions worldwide. COVID-19 is caused by the novel severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) epidemic. Also, several viral epidemics have been listed in the last two decades, like the middle east respiratory syndrome coronavirus (MERSCoV) and the severe acute respiratory syndrome coronavirus 1 (SARSCoV-1), which cause MERS, and SARS diseases, respectively. Detection of these viral epidemics is a difficult issue because of their genetic similarity. In this paper, an effective automated system was developed to classify these viral epidemics using their complete genomic sequences via the genomic image processing techniques to facilitate the diagnosis and increase the detection accuracy in a short time. Results achieved an overall accuracy of 100% using two classifiers: SVM and KNN. However, the KNN classifier shows a privilege over the SVM in the execution time performance.

Interference management is one of the challenging tasks in Long-Term Evolution (LTE) technologies in Telecom Networks. One of these tasks is classifying interference problems affecting Uplink (UL) channel into different types. The interference classification problem can be formulated as an image classification task by converting the signal's power spectral density to an image. Convolutional Neural Networks (CNN) proved to have great success in image classification tasks. In this paper, different CNN architectures such as (VGG, MobileNet, RESNET) are used and assessed to classify the type of interference affecting the uplink channel in LTE. CNNs are characterized by their ability to detect and describe the abnormal behavior of UL channel which provided significant improvement over traditional rule-based systems. These rule-based systems rely on extracting domain driven features and classifying the interference using manually created rules by an expert. Our study shows that CNN yields 95% accuracy with training data. The end-to-end solution was deployed in Vodafone Group on Google Cloud Platform (GCP) to serve the different Local Markets.

The simulation of quantum transport in DG-MOSFETs could be effectively accomplished by the Partial-Coupled Mode Space (PCMS) approach, which is realized by separating the odd and even modes solutions. This technique combines the merits of Coupled Mode Space (CMS) regarding the accuracy and Uncoupled Mode Space (UMS) as far as reducing computational time is concerned. In this work, a comparison study between PCMS using our developed FETMOSS simulator and CMS using Silvaco TCAD is carried out. The simulation is performed on a set of short-channel DG-MOSFETs. The accuracy at room temperature is found to be less than 8% along the whole range of the supply voltage. Based on this study, the PCMS approach in FETMOSS simulator is validated and proved to trace device performance in reasonable times compared to the TCAD high computational times.

This study attempts to visualize the whole retina and its anatomical structures using only a single hologram giving the ophthalmologist an opportunity to examine it. Since all fundus cameras capture images for only a portion of the retina, retinal image registration was first applied to the captured images of the same eye to obtain a mosaic containing the complete map of the retina, allowing proper diagnosis. Then, accurate morphological detection of the main anatomical structures of the retina including blood vessels, macula and optic disc which are extremely important signs for estimating retinal disorders were extracted and/or highlighted on the mosaic. Subsequently, computer-generated holograms (GHs) of the mosaic, blood vessels, macula and optic disc were calculated using an adapted iterative approach based on the well-known Gerchberg-Saxton (GS) algorithm. The resulting CGHs were then holographically projected using a reflective phase-only spatial light modulator (SLM). In conclusion, the integration of CGH with fundus photography can be a valuable and crucial diagnostic tool for retinal disorders and can make significant contributions in the field of ophthalmology.

In conclusion, the integration of CGH with fundus photography can be a valuable and crucial diagnostic tool for retinal disorders and can make significant contributions in the field of ophthalmology.","PeriodicalId":249153,"journal":{"name":"2021 3rd Novel Intelligent and Leading Emerging Sciences Conference (NILES)","volume":"29 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132707465","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}
