Existing techniques for digital profiling of tumor micro environment have common limitations; they require a lot of training data, are computationally costly and don’t perform well in challenging scenarios where nuclei exhibit varying inter and intra class characteristics. Hence, to address the challenges of segmenting and classifying nuclei given their vast morphometric properties, we propose a deep learning based model where we use pixel distances from their respective nuclei center points to separate touching and overlapping nuclei. We incorporate attention mechanism to learn complex features of nuclei and refine representation for high accuracy classification. The proposed methodology is assessed on two publicly accessible H&E stained multi-organ histology datasets. We demonstrate higher performance of our model by comparing with recently published algorithms.","PeriodicalId":207832,"journal":{"name":"2021 International Conference on Digital Futures and Transformative Technologies (ICoDT2)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115763329","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}

One of the most significant task in this pandemic is to accurately and efficiently diagnose the COVID-19 patients and to monitor them to make prompt decisions and take appropriate actions for their monitoring, management and treatment. The early diagnosis of COVID-19 was a very troublesome and difficult challenge that CAD (Computer-Aided Diagnosis) methods successfully tackled. The CXR (chest X-ray) method proved to be a very low-cost and effective alternative to Computed Tomography (CT) scan and Real Time Polymerase Chain Reaction (RT-PCR) test, which were previously the most commonly used methods for COVID-19 diagnosis. Till now, very few CAD based techniques have been proposed to effectively detect COVID-19, but their efficiency is limited due to a number of factors. In this study, we have proposed a deep learning model using the Convolutional Block Attention Module with ResNet32. For training the model, Kaggle’s dataset containing CXR images has been used. The dataset contains a total of 3886 images. Moreover, 64% of data has been used for training, 20% for testing and 16% for validation. We have experimented with different CNN architectures with different approaches like Transfer Learning, Data Augmentation and attention module. With 97.69% accuracy, the ResNet32 with attention module outperformed other architectures and approaches, improving the baseline network efficiency. This promising and efficient classification accomplishment of our proposed methodology demonstrates that it is well suited for CXR image classification in COVID-19 diagnosis in terms of both accuracy and cost.","PeriodicalId":207832,"journal":{"name":"2021 International Conference on Digital Futures and Transformative Technologies (ICoDT2)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127491348","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}

Fog has provided tremendous advantages over cloud computing which include low latency rate, improved real-time interactions, reduced network traffic overcrowding, and improved reliability, however, security concerns need to be addressed separately. Another major issue in the cloud is Cloud Lock-in/Vendor Lock-in. Through this research, an effort has been made to extend fog computing and Searchable Encryption technologies. The proposed system can reduce the issue of cloud lock-in faced in traditional cloud computing. The SE schemes used in this paper are Symmetric Searchable Encryption (SSE) and Multi-keyword Ranked Searchable Encryption (MRSE) to achieve confidentiality, privacy, fine-grained access control, and efficient keyword search. This can help to achieve better access control and keyword search simultaneously. An important use of this technique is it helps to prevent the issue of cloud/vendor lock-in. This can shift some computation and storage of index tables over fog nodes that will reduce the dependency on Cloud Service Providers (CSPs).","PeriodicalId":207832,"journal":{"name":"2021 International Conference on Digital Futures and Transformative Technologies (ICoDT2)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116327864","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}

Different object detection models are available but in case of weapons detection it is difficult to detect the weapons of distinctive size and shapes along with the different colors of the background. Currently, a great deal of Convolutional Neural Network (CNN) based deep learning approaches are proposed for the recognition and classification in real-time. In this paper, we have done the comparative analysis of the two versions which is a state of the art model called YOLOV3 and YOLOV4 for weapons detection. For training purpose, we create weapons dataset and the images are collected from google images along with a portion of different assets. We annotate the images one by one manually in different formats in light of fact that YOLO needs annotation file in text format and some other models need annotation file in XML format. We trained both the versions on a large data set of weapons and afterward tested their results for comparative analysis. We explained in the paper that YOLOV4 performs obviously superior to the YOLOV3 in terms of processing time and sensitivity yet we can compare these two in precision metric.

There exists a lot of work in this area but still, it needs many improvements making use of the state-of-the-art technologies.

Emergency patient management system functionality includes patient registration, payments, and patient discharge modules. In software development, UML is a standardized modelling language that is used to portray the model of a software system requirement comprehensively. IoT healthcare devices are utilized to track a patient’s health condition and actors are employed to take decisions as specified.
