    A Note on Intuitionistic Fuzzy Hypervector Spaces

    Full text link
    The notion of Intuitionistic fuzzy hypervector space has been generalized and a few basic properties on this concept are studied. It has been shown that the intersection and union of an arbitrary family of Intuitionistic fuzzy hypervector spaces are also Intuitionistic fuzzy hypervector space. Lastly, the notion of a linear transformation on a hypervector space is introduced and established an important theorem relative to Intuitionistic fuzzy hypervector spaces.Comment: 13 page

    A Note on Hypervector Spaces

    Full text link
    The main aim of this paper is to generalize the concept of vector space by the hyperstructure. We generalize some definitions such as hypersubspaces, linear combination, Hamel basis, linearly dependence and linearly independence. A few important results like deletion theorem, extension theorem, dimension theorem have been established in this hypervector space.Comment: 17 page

    Quasi fuzzy delta compact spaces and a few related properties

    Full text link
    In this paper, we introduce the concept of various types fuzzy delta (δ)(\delta) compactness such as Quasi fuzzy delta compact, Quasi fuzzy countably delta compact, Weakly fuzzy delta compact, aa-delta compact, Strong fuzzy delta compact, Ultra fuzzy delta compact and Fuzzy delta compact and characterize these types of fuzzy delta compactness using the notion of fuzzy upper limit of net of some types of delta (δ)(\delta) closed sets

    <p>Abstract</p> <p>Background</p> <p>The DNA repair and recombination (DRR) proteins protect organisms against genetic damage, caused by environmental agents and other genotoxic agents, by removal of DNA lesions or helping to abide them.</p> <p>Results</p> <p>We identified genes potentially involved in DRR mechanisms in <it>Arabidopsis </it>and rice using similarity searches and conserved domain analysis against proteins known to be involved in DRR in human, yeast and <it>E. coli</it>. As expected, many of DRR genes are very similar to those found in other eukaryotes. Beside these eukaryotes specific genes, several prokaryotes specific genes were also found to be well conserved in plants. In <it>Arabidopsis</it>, several functionally important DRR gene duplications are present, which do not occur in rice. Among DRR proteins, we found that proteins belonging to the nucleotide excision repair pathway were relatively more conserved than proteins needed for the other DRR pathways. Sub-cellular localization studies of DRR gene suggests that these proteins are mostly reside in nucleus while gene drain in between nucleus and cell organelles were also found in some cases.</p> <p>Conclusions</p> <p>The similarities and dissimilarities in between plants and other organisms' DRR pathways are discussed. The observed differences broaden our knowledge about DRR in the plants world, and raises the potential question of whether differentiated functions have evolved in some cases. These results, altogether, provide a useful framework for further experimental studies in these organisms.</p

    Operation Control and Analysis of a Hybrid AC/DC Microgrid

    Distributed renewable energy production is making smart microgrid concepts based on AC, DC, and hybrid-MG design more attractive (DRE). In light of the growing population and the pressing need to minimize the load, research into effective control techniques and architectural solutions is a hot topic right now. However, a comprehensive and coordinated literature assessment of hierarchical control approaches based on diverse configurations of the microgrid (MG) architecture has been explored relatively little in the past.\u27\u27 Primary, secondary, and tertiary methods to MG system control are outlined in this suggested method. Primary, secondary and third-tier techniques are examined for each MG structure in a short literature review. In addition, the paper offers the best and worst aspects of current control methods. In addition, a simulation research connected to the literature review\u27s future trends in MG control is offered as a further contribution to this subject. Since renewable energy supplies are intermittent in nature, a hybrid microgrid is needed to minimize overall deficit inadequacies and increase system dependability. This is due to the depletion of natural resources and to the intermittent nature of renewable energy resources. Using a hybrid microgrid, the present distributed and concentrated load situations may be accommodated. In order to better understand how the hybrid microgrid may be integrated, optimized and controlled, there is a growing demand for research. It is necessary to do a thorough evaluation of the performance, efficiency, dependability, security, design flexibility, and cost-effectiveness of a hybrid microgrid. Issues such as AC and DC microgrids integrating into a single hybrid microgrid are discussed in this paper, as well as how to manage renewable energy resources in a cost-effective manner and how to place the optimal number of feeders in a microgrid. There is a quick overview of the primary research fields, with the goal of finding the research gap that may further enhance the grid\u27s performance. \u27\u27New hybrid microgrid solutions are being offered in light of current study trends that have been determined to be the most effective and most-friendly. Research, comparative analysis, and further development of new methodologies related to hybrid microgrids will be aided by this study as the foundation for future wor

    An evaluation of phase change microcapsules for use in enhanced heat transfer fluids

    Full text link
    The results of an experimental study to evaluate the properties of microencapsulated phase change materials have been presented. Two phase change materials, n-eicosane and stearic acid, have been used in the study. The microcapsules were manufactured with two different wall thickness, comprising of approximately 15% and 30% of the total microcapsule volume. Three different microcapsule sizes ranging from 50[mu] to 250[mu] have been considered. The microcapsules with thinner walls are unable to withstand repeated thermal cycling past the melting point. However, the microcapsules with thicker walls were found to be both structurally as well as thermally stable.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29260/1/0000317.pd
