    Neutrinos from Stellar Collapse: Comparison of signatures in water and heavy water detectors

    Get PDF
    Signatures of neutrino and antineutrino signals from stellar collapse in heavy water detectors are contrasted with those in water detectors. The effects of mixing, especially due to the highly dense matter in the supernova core, are studied. The mixing parameters used are those sets allowed by current understanding of available neutrino data: from solar, atmospheric and laboratory neutrino experiments. Signals at a heavy water detector, especially the dominant charged current reactions on deuteron, are very sensitive to some of these sets of allowed mixing parameters. Theoretical uncertainties on supernova neutrino spectra notwithstanding, a combination of supernova measurements with water and heavy water detectors may be able to distinguish many of these mixing possibilities and thus help in ruling out many of them.Comment: 36 pages Latex file, with 13 postscript figures; important improvements in the analysis and more detailed presentation of results.

    High Performance of CSI Fed IM Drives at Low Speed operation with MRAS Based Estimation of Stator Resistance

    Get PDF
    This paper is proposed to improve the performance of sensorless vector controlled CSI fed induction motor drives during low-speed operations. In general the performance of sensorless vector controlled induction motor drives is poor at very low speed due to stator resistance variations and the estimated flux and torque deviates from its set value. Therefore online tuning of the stator resistance is necessary at very low speed. The performance and efficiency of an induction motor drive system can be enhanced by online tuning of stator resistance. A novel model reference adaptive system (MRAS)-based algorithm for simultaneous identification of stator resistance (Rs) and rotor speed (ðŽr) implemented in sensorless Field oriented controlled CSI fed induction motor. The reference model and adjustable model are interchangeable for concurrent ðŽr and Rs estimation in the low-speed operating region is investigated. The simulation and experimental results are proved that the proposed method is improving the performance of the drive system at low speed operation

    Universal Experience of Female Tribulations in an Indian Milieu: A Study on Deshpande's Novels Small Remedies and Roots and Shadows

    Though sexual politics is not something new but a universal experience of women, third wave feminism has acknowledged the differences like colours, ethnicities, regions, etc. and has started analysing how the experience of women is something that cannot be universalised but is different for women depending on their cultural background. This paper analyses the experience of middle class women in Indian scenario and how the gap between traditionalists and the educated middle class women in India leads to chaos and confusions in the society and how it imposes great pressure on the women to act according to the rules of the patriarchal community in the society using the selected novels of Sashi Deshpande. It also examines different forms of gender-specific discrimination targeted against women in Indian society

    Anthropocentrism in the Select American Dystopic Fictions: The Water Knife by Paolo Bacigalupi and Claire Vaye Watkins’ Gold Fame Citrus

    A conductive environment is the most crucial thing for any living being to lead life happily in the world. The environment includes both biotic and abiotic components. At present, people are facing more problems due to environmental issues. This research paper aims to see anthropocentrism through the interaction between humans and the environment in the select American dystopic fictions The Water Knife by Paolo Bacigalupi and Gold Fame Citrus by Claire Vaye Watkins. These novels' major themes deal with climate change, water shortage, drought, and other ecological crises. In this research, a qualitative approach has been taken up as a method. The result of the study reveals that humans have more responsibilities to protect water bodies and the environment. People need to follow ethics effectively and not be involved in anthropocentric activities to come out of water shortages. The study reminds us that nature is more powerful than man

    THE LIMITATIONS OF NORMATIVE ETHICS: ANTHROPOCENTRISM IN KIM STANLEY ROBINSON’S 2312

    Get PDF
    Purpose of the study: The present study mainly argues the limitations of normative ethics and analyzes the anthropocentrism in Kim Stanley Robinson’s 2312 based on the actions or duties of the characters. Methodology: The article used normative ethics as a methodology. Normative ethics is the study of ethical actions that has certain rules and regulations about how we ought to do and decide. So, this study has chosen a normative ethic that consists of three ethical theories Utilitarian approach, Kantian ethics and Virtue ethics to judge duties that are right and wrong.   Main Findings: As a result, normative ethics compact with a one-dimensional approach. All three ethics deal with its own specific code of ethics. Utilitarianism has focused on good outcomes. Kantian ethics has paid attention to good rules with duty. Virtue ethics focused on the good people but all three theories have a strong common objective of focusing on only human beings (sentient entities) and omit other entities (plants and animals). So all normative ethics have certain limitations and do their duties without thinking about consequences and situations. In conclusion, this code of normative ethics has provoked as anthropocentric. In addition that Swan’s actions and the rational behavior made her miserably failed in Mercury through the construction of the biome and creation of quantum computers. So this cause, in the end, the space people want to move from space to earth to rebuild the biome. Applications of this study: The prudent study analyses the normative ethics in a detailed manner under the Utilitarian approach, Kantian ethics and Virtue ethics. These philosophical domains can be benefitted for researchers to practice and implement during the research process in Humanities and Social Sciences especially. Novelty/Originality of this study: The study analyzed the anthropocentric attitude of the character Swan in 2312 based on her actions or duties through the code of normative ethics (Utilitarianism, Kantian ethics and Virtue ethics)

    An Congestion Control Based Cluster Approach for Effective Communication in VANET

    Clustering in VANET is major controlling method used to make VANET worldwide topology less dynamic. Many of the VANET clustering methods are derived from mobile ad hoc networks (MANET). In any case, VANET hubs are portrayed by their high versatility, and the presence of VANET hubs in the same geographic area does not imply that they show a similar portability designs. Along these lines, VANET grouping plans should contemplate over the level of the speed distinction among neighboring hubs to create moderately stable clustering structure. In this paper, we present another bunching system reasonable for the VANET condition on thruways with the point of upgrading the steadiness of the system topology. This method takes the speed distinction as a parameter to make moderately stable group structure. In this paper proposed to built up another multi-metric calculation for cluster head decisions. A reproduction was directed to assess our strategy and contrast it and the most usually utilized grouping strategies

    An Analysis of Disability in The Little Mermaid: Examining Disparities and Similarities in the Fairytale and Its Movie Adaptation

    Get PDF
    Differences and disabilities have always been a part of oral tradition and folklore. These differences greatly influenced story-telling that eventually stemmed from oral tradition. The western canon has included disability in their literature for some time now, but their portrayal of disability from the beginning to the twentieth century has drastically improved. Fairytales and folktales were historically associated with values and morals, and the moral system during the olden times was completely patriarchal and abelistic. The tales never offered any space for disability to exist as a simple part of an individual's life. This paper aims to investigate the representation of disability in Disney's version of Hans Christian Andersen's fairytale, "The Little Mermaid", and attempts to understand disability in the light of fairytales. There are some major and vital differences between the original story by Hans Christian and the movie by Disney, but do they accommodate positive signals that counteract the ableist society? Does the movie reflect the truth about a disabled person's life? Or is it still a profusion of negative elements that reinforce oppression and discrimination? This paper examines the narratives employed in the movie and the original fairy tale and attempts to address the issues of identity, stigma, and stereotypes based on the representation of disability in both genres

    Threshold Effects on Quasi-degenerate Neutrinos with High-scale Mixing Unification

    Get PDF
    We consider threshold effects on neutrino masses and mixings in a recently proposed model for understanding large solar and atmospheric mixing angles using radiative magnification for the case of quasi-degenerate neutrinos. We show that the magnitude of the threshold effects is sufficient to bring concordance between the predictions of this model and latest data from KamLAND{\rm KamLAND} and SNO{\rm SNO} on observations of neutrino oscillations.Comment: Four pages, no figure
