    ABSTRACT-This paper gives an overview of how Hadoop File System manages massive data as well as handles small files. As data is exponentially pouring in from all sides in all domains, it has become a necessity to manage and analyze such huge amount of data to extract useful information. This huge amount of data is technically termed as Big Data, which in turn falls under Data Science. Currently a lot of research is going on how to handle such vast pool of data. The Apache Hadoop is a software framework that uses simple programming paradigm to process and analyze large data sets(Big Data) across clusters of computers. The Hadoop Distributed File System(HDFS) is one such technology that manages the Big Data efficiently. In this paper, an insight of "how HDFS handles big as well as small amount of data" is presented, reviewed and analyzed. As a result, summarized limitations of existing sys-tems are described in the paper along with the future scope of it

    The medicinal traits of Callicarpa macrophylla Vahl. have been used in traditional and folklore medicinal system, however, scientific evaluation of such medicinal plants have not been much explored yet. Different solvent extracts of the whole plant of C. macrophylla from the Himalayan region are the key subject of interest to evaluate and exhibit their antioxidant properties concerning its phytochemical composition. The different polarity extracts of C. macrophylla were prepared using the Soxhlet apparatus and both of their GC-MS profile outlined their individual components. The antioxidant activity of both extracts was evaluated for DPPH radical scavenging activity, metal chelating activity, and reducing power activity. Thirty-two compounds were identified in the hexane extract, accounting for 63.56% of the total extract composition with tetratetracontane (9.78%), as the prominent compound. A sum of 26 compounds making up 79.74% of the total methanolic extract composition was identified and the major compound was a diterpenoid, trachylobane (31.87%). The methanolic extract exerted potent antioxidant properties when compared, in vitro, to hexane extract as it showed better IC50 values of DPPH radical scavenging activity (91.97 ± 0.33 µg/ml), metal chelating activity (10.90 ± 1.40 µg/ml) and reducing power activity (56.72 ± 0.67 µg/ml). The antioxidant potential of the methanolic extract was also comparable to standards. Therefore, the methanolic extract exhibited better results as compared to hexane extract and had comparable potential with standards in vitro, if further explored might be utilized as an antioxidant agent in various pharmaceutical and cosmetic industries

    Abstract Route prediction is an essential requirement for many intelligent transport systems (ITS) services like VANETS, traffic congestion estimation, resource prediction in grid computing etc. This work focuses on building an end-to-end horizontally scalable route prediction application based on statistical modeling of user travel data. Probabilistic suffix tree (PST) is one of widely used sequence indexing technique which serves a model for prediction. The probabilistic generalized suffix tree (PGST) is a variant of PST and is essentially a suffix tree built from a huge number of smaller sequences. We construct generalized suffix tree model from a large number of trips completed by the users. User trip raw GPS traces is mapped to the digitized road network by parallelizing map matching technique leveraging map reduce framework. PGST construction from the huge volume of data by processing sequentially is a bottleneck in the practical realization. Most of the existing works focused on time-space tradeoffs on a single machine. Proposed technique solves this problem by a two-step process which is intuitive to execute in the map-reduce framework. In the first step, computes all the suffixes along with their frequency of occurrences and in the second step, builds probabilistic generalized suffix tree. The probabilistic aspect of the tree is also taken care so that it can be used as a model for prediction application. Dataset used are road network spatial data and GPS traces of users. Experiments carried out on real datasets available in public domain

    Objective: The purpose of this research was to examine patients' periodontal health before, during, and after treatment using a fixed orthodontic device. Methods: Forty normal teenagers with full sets of permanent teeth and a clinical need for fixed orthodontics participated. Individuals were chosen from the Class I population who would benefit from utilizing traditional orthodontic braces and techniques that did not need extractions. Respondents were sent to the periodontist for required checkups after the placement of a fixed orthodontic device at 3-, 6-, 12-, and 24-month intervals, respectively, till the conclusion of orthodontic treatment. Results: After having a fixed orthodontic device put in place, patients had a rise in the average values of the Plaque Index and Sulcus Bleeding Index at each checkup. Keeping an eye on the progression three months, six months, a year, and two years after the initiation of orthodontic treatment reveals a statistically significant difference in the presence of gingival hyperplasia. Conclusion: Patients' periodontal health before, during, and after fixed orthodontic treatment shows the need for close collaboration between the orthodontist and the periodontis

    A study to assess knowledge, attitude, and perception of dental practitioners on minimally invasive dentistry concepts

    No full text
    Background: Minimally invasive dentistry (MID) includes caries detection using caries risk assessment (CRA), early localization of nascent carious sores including necessary and voluntary avoidance, and remineralization of demineralized veneer and dentin when diagnosed early for these reasons. Although the dentistry curriculum prioritizes the benefits of MID in tooth protection, this research is seldom included in classroom instruction. Aim: The purpose of this research was to gauge the level of understanding that dental professionals have about MID ideas. Methods: An online questionnaire measuring MID knowledge and application was used to compile the data. The Chi-square tests were run for statistical analysis in the Statistical Package for the Social Sciences (SPSS). Results: Just 42.2% of the dentists who replied had MID training during their undergraduate or internship years, and the majority of that training came via lectures (45.2%). The majority (almost 81%) of respondents believed that CRA should be performed on all patients. Differences in knowledge and experience with atraumatic restorative therapy and the sandwich approach for treating caries in permanent teeth and high caries risk children were shown to be statistically significant (P 0.05). Conclusion: Dentists know about the benefits of MID, but their patients are not reaping those benefits since so many dentists still use the old methods of treating complete caries
