    The study presents the trends in authorship pattern and authors collaborative research in Astrophysics with a sample of 411 articles during the period 2008-2017. The study found single author has contributed 133 with (32.3 %), Multi authored articles are dominant i.e. 278 (67.6 %). The mean value for the overall degree of collaboration for the 2008-2017 is found to be 0.67, the collaboration index increased from 5.18 in 2008 to 8.22 in 2017 with an average of 4.00. The collaborative co-efficient for the year 2008 is 0.51 which increased gradually to 0.54 in 2017 with an average of 0.49. The most prolific author is Del Zanna, Giulio who published 15 publications followed by Spitaleri, C. published 10 publications. Without Collaboration stood first place in levels of collaboration with 133 (32.3%)

    Performance and Analysis of a U-Net Model for Automated Skin Lesion Segmentation

    A greater proportion of people are affected by skin cancer, particularly melanoma, which has a higher tendency to metastasize. For Dermatologist, Visual inspections are most challenging & complex task for melanoma detection. To solve this problem, dermoscopic images are analyzed and segmented. Due to the sensitivity involved in surgical operations, existing techniques are unable to achieve higher accuracy. As a result, computer-aided systems are essential to detect & segment dermoscopic images.     In this paper, for segmentation 5000 skin images were taken from the HAM10000 dataset. Prior to segmentation, preprocessing is done by resizing images. A novel U Net structure is a fully convolutional network is presented & implemented using up-sampling and down-sampling technique with Rectified Linear Units (ReLU) for activation functions. The outcomes of proposed methodology shows performance improvement for skin-lesion segmentation with 94.7 % pixel accuracy & 89.2 % dice coefficient compared with existing KNN & SVM techniques

    In the current digital era, ensuring that everyone has access to information, regardless of their ability or disability, is a key component of library and information science. There has been an upsurge in the number of impaired students enrolling in universities in recent years. Regardless of their capacity to address the issues of inclusion and social justice, libraries are required to offer information to all visitors. Because a sizable segment of our population is attempting to integrate into society, these special users need special care. Academic libraries must be outfitted with various Assistive Technologies (AT) in order to meet the needs of individuals with disabilities and help this underserved community become self-sufficient. The adoption of assistive technologies by individuals with disabilities encourages more equity in the social, academic, and economic public spheres

    A Survey on Anonymous On-Demand Routing Protocols for MANETs

    No full text
    At present Mobile ad hoc networks (MANET) is used in many real time applications and hence such networks are vulnerable to different kinds of security threats. MANET networks suffered more from security attacks due to use of free wireless communication frequency spectrum and dynamic topology. Therefore it becomes very tough to provide security to MANET under different adversarial environments like battlefields. For MANET, anonymous communications are vital under the adversarial environments, in which the identification of nodes as well as routes is replaced by pseudonyms or random numbers for the purpose of protection. There are many protocols presented for anonymous communication security for MANET, which hide node identities and routes from exterior observers in order to provide anonymity protection. This paper presents review of various anonymous on demand routing protocols
