    Impact of Digital Technology on Library Resource Sharing: Revisiting LABELNET in the Digital Age

    The digital environment has facilitated resource sharing by breaking the time and distance barriers to efficient document delivery. However, for the librarians, this phenomenon has brought more challenging technical and technological issues demanding addition of more knowledge and skills to learn and new standards to develop. The overwhelming speed and growing volume of digital information is now becoming unable to acquire and manage by single libraries. Resource sharing, which used to be a side business in the librarianship trade, is now becoming the flagship operation in the library projects

    PVSNet: Palm Vein Authentication Siamese Network Trained using Triplet Loss and Adaptive Hard Mining by Learning Enforced Domain Specific Features

    Designing an end-to-end deep learning network to match the biometric features with limited training samples is an extremely challenging task. To address this problem, we propose a new way to design an end-to-end deep CNN framework i.e., PVSNet that works in two major steps: first, an encoder-decoder network is used to learn generative domain-specific features followed by a Siamese network in which convolutional layers are pre-trained in an unsupervised fashion as an autoencoder. The proposed model is trained via triplet loss function that is adjusted for learning feature embeddings in a way that minimizes the distance between embedding-pairs from the same subject and maximizes the distance with those from different subjects, with a margin. In particular, a triplet Siamese matching network using an adaptive margin based hard negative mining has been suggested. The hyper-parameters associated with the training strategy, like the adaptive margin, have been tuned to make the learning more effective on biometric datasets. In extensive experimentation, the proposed network outperforms most of the existing deep learning solutions on three type of typical vein datasets which clearly demonstrates the effectiveness of our proposed method.Comment: Accepted in 5th IEEE International Conference on Identity, Security and Behavior Analysis (ISBA), 2019, Hyderabad, Indi

    A multimodal investigation in eye movements

    While functional magnetic resonance imaging (fMRI) has identified which regions of interest (ROIs) are functionally active during a vergence movement (inward or outward eye rotation), task-modulated coactivation between ROIs is less understood. This study tests the following hypotheses: (1) significant task-modulated coactivation would be observed between the frontal eye fields (FEFs), the posterior parietal cortex (PPC), and the cerebellar vermis (CV); (2) significantly more functional activity and task-modulated coactivation would be observed in binocularly normal controls (BNCs) compared with convergence insufficiency (CI) subjects; and (3) after vergence training, the functional activity and task-modulated coactivation would increase in CIs compared with their baseline measurements. A block design of sustained fixation versus vergence eye movements stimulates activity in the FEFs, PPC, and CV. fMRI data from four CI subjects before and after vergence training are compared with seven BNCs. Functional activity is assessed using the blood oxygenation level dependent (BOLD) percent signal change. Task-modulated coactivation is assessed using an ROI-based task modulated coactivation analysis that reveals significant correlation between ROIs

    Trade impact of SADC-India FTA on textiles and clothing sectors

    Pluri-lateral trade agreements have been the topic of the hour in trade circles, since late 2000’s, though they have been slowed down in recent trade policy developments in UK and USA. However, countries like India and African nations that have been left out of such mega deals have been considering striking deals among themselves. In this paper, we examine the potential impact of India-SADC (South African Development Community) FTA on these countries, especially focusing on their crucial Textiles and Clothing (T&C) sectors. Apart from the widely used GTAP framework, we also employ the Revealed Comparative Advantage (RCA) analysis in conjunction with it, to draw implications on FTA impct on RCA, which is mostly positive as per our analysis. Otherwise, India stands to gain, while the SADC countries have mixed effects across sectors, with an overall positive effects

    This paper is not a research project or an experimental study. It is based on my own experiences, on discussions with I.E. directors who felt they lacked adequate training, and on discussions with seasoned\u27 directors who have aided new directors and new programs

    A Proposal towards Detection of Sybil Attack Using Sink Based Detection Mechanism in Wireless Sensor Networks

    Get PDF
    Recent advances in wireless and electronic communications have enabled the deployment of low-cost, low-cost, low-power, multi-function sensors and communicate in a nutshell. Intelligent and economical sensors, connected to the network via wireless links and distributed in large quantities, offer unprecedented opportunities to monitor and control homes, cities and the environment. In addition, sensors connected to the network use a wide range of applications within the defence area, generating new features for recognition and surveillance and various tactical applications. Sybil is one of the most terrible attacks is the cloning attack of the node, where the attacker captures the knot and extracts its secret information, create replicas and enter them in the network field other malevolent behaviour. In this paper, to detect and mitigate this attack, sink-based detection schemes have been proposed

    Renal Cell Carcinoma Presenting as Metastasis to Scrotum and Spermatic Cord

    Unusual site metastasis as presenting complaint of renal cell carcinoma (RCC) has been reported previously in literature. RCC is a notorious tumor with unpredictable behavior. We present a case of RCC who presented with scrotal mass and on subsequent investigation was found to have metastasis to scrotum and spermatic cord. Both testes were normal with no evidence of metastasis
