    Get PDF
    Peer review is an established form of trust-marking and ensuring quality of scholarly communications. The advent of Internet has had its impact on peer review also. This paper examines the existing approaches of peer review utilizing the Internet. Future approaches, challenges and proposal of a framework for open peer review of directly published scholarly communication on the Internet is also discussed

    Cyber-pharmacies and emerging concerns on marketing drugs Online

    Get PDF
    The booming e-commerce and a regulation-less environment online have led to the rise of a new generation of websites that market drugs and other products over the Internet. Some of these drugs are often herbal products or of dubious quality, often marketed with a mix of professional design and unverified/fraudulent claims. Several concerns have arisen from different corners and evidence of malpractice has emerged. But there is a lack of sufficient evidence confirming the concerns

    Open, Online and Global: Benefits of BioMedical Journals Going Online and Open

    The emergence of Internet affords the immense possibility for scientific publications to be indexed, linked, copied, archived, redistributed and searched at ease and at a lower production cost. This has paved the way for the emergence of Online-Only Journals like the Online Journal of Health and Allied Sciences. This has also spurred the rise of Open Access movements spearheaded by the Budapest Open Access Initiative and the Public Library of Science. 'Open Access' means immediate, permanent, toll-free, non-gerrymandered, online access to the full-text. Open Access can be considered as borne on three major pillars of Open Access Publishing, Open Access Archiving and Open Access Support and Open Access publishing is perhaps the future of scientific communicatio

    Adaptive Digital Scan Variable Pixels

    The square and rectangular shape of the pixels in the digital images for sensing and display purposes introduces several inaccuracies in the representation of digital images. The major disadvantage of square pixel shapes is the inability to accurately capture and display the details in the objects having variable orientations to edges, shapes and regions. This effect can be observed by the inaccurate representation of diagonal edges in low resolution square pixel images. This paper explores a less investigated idea of using variable shaped pixels for improving visual quality of image scans without increasing the square pixel resolution. The proposed adaptive filtering technique reports an improvement in image PSNR.Comment: 4th International Conference on Advances in Computing, Communications and Informatics, August, 201

    Predicting computational reproducibility of data analysis pipelines in large population studies using collaborative filtering

    Full text link
    Evaluating the computational reproducibility of data analysis pipelines has become a critical issue. It is, however, a cumbersome process for analyses that involve data from large populations of subjects, due to their computational and storage requirements. We present a method to predict the computational reproducibility of data analysis pipelines in large population studies. We formulate the problem as a collaborative filtering process, with constraints on the construction of the training set. We propose 6 different strategies to build the training set, which we evaluate on 2 datasets, a synthetic one modeling a population with a growing number of subject types, and a real one obtained with neuroinformatics pipelines. Results show that one sampling method, "Random File Numbers (Uniform)" is able to predict computational reproducibility with a good accuracy. We also analyze the relevance of including file and subject biases in the collaborative filtering model. We conclude that the proposed method is able to speedup reproducibility evaluations substantially, with a reduced accuracy loss

    Literature Survey on Secure Multiparty Anonymous Data Sharing

    The  popularity of internet as a communication medium whether for personal or business requires anonymous communication in various ways. Businesses also have legitimate reasons to make communication anonymous and avoid the consequences of identity revelation. The problem of sharing privately held data so that the individuals who are the subjects of the data cannot be identified has been researched extensively. Researchers have understood the need of anonymity in various application domains: patient medical records, electronic voting, e-mail, social networking, etc. Another form of anonymity, as used in secure multiparty computation, allows multiple parties on a network to jointly carry out a global computation that depends on data from each party while the data held by each party remains unknown to the other parties. The secure computation function widely used is secure sum that allows parties to compute the sum of their individual inputs without mentioning the inputs to one another. This function helps to characterize the complexities of the secure multiparty computation. Keywords:Anonymity,Secure multiparty computatio

    Spline network modeling and fault classification of a heating ventilation and air-conditioning system

    A spline network, that is an alternative to artificial neural networks, is introduced in this dissertation. This network has an input layer, a single hidden layer, and an output layer. Spline basis functions, with small support, are used as the activation functions. The network is used to model the steady state operation of a complex Heating Ventilation and Air-conditioning (HVAC) system. Real data was used to train the spline network. A neural network was also trained on the same set of data. Based on the training process, it is possible to conclude that when compared to artificial neural networks, the spline network is much faster to train, needed fewer input-output pairs, and had no convergence problems. The weights of the spline network are obtained by solving a set of linear equations;The spline network model of the HVAC system is used to detect faulty operation of the actual system. Once abnormal operation of the system is monitored, a fuzzy neural network is used to locate the faulty component. The fuzzy neural network is trained on data obtained by simulating fault scenarios. This network minimizes ambiguities at decision boundaries. The results of fault classification are presented in the dissertation

    Application of mathematical morphology to the analysis of X-ray NDE images

    Ever since the beginning, man has been in the relentless pursuit of perfection. From stone age to space age, from caves to condominiums, from carts to planes, trains and automobiles, his drive for consummation has grown considerably. The high quality products that are available in the market at the turn of the twenty first century are living legacies of his unyielding endeavor for excellence. But one fact that most people do not realize is the amount of time and money devoted to quality control and non- destructive evaluation (NDE) that is responsible for the high quality of products. In the past, people used to tap earthenware and other materials as a means of non destructive testing for defects in the material. They could sense the defects by the nature of the sound propagated through the material. The ultrasonic method of NDE is an extension of this principle
