Bianchi Type V String Cosmological Models in General Relativity

Bianchi type V string cosmological models in general relativity are investigated. To get the exact solution of Einstein's field equations, we have taken some scale transformations followed by Camci $\it et ~ al$ (2001). It is shown that Einstein's field equations are solvable for any arbitrary cosmic scale function. Solution for particular form of cosmic scale functions are also obtained. Some physical and geometrical aspects of the models are discussed.Comment: 12 pages, Accepted version in Pramana - J. Physic

Lexicon Infused Phrase Embeddings for Named Entity Resolution

Most state-of-the-art approaches for named-entity recognition (NER) use semi supervised information in the form of word clusters and lexicons. Recently neural network-based language models have been explored, as they as a byproduct generate highly informative vector representations for words, known as word embeddings. In this paper we present two contributions: a new form of learning word embeddings that can leverage information from relevant lexicons to improve the representations, and the first system to use neural word embeddings to achieve state-of-the-art results on named-entity recognition in both CoNLL and Ontonotes NER. Our system achieves an F1 score of 90.90 on the test set for CoNLL 2003---significantly better than any previous system trained on public data, and matching a system employing massive private industrial query-log data.Comment: Accepted in CoNLL 201

Tourist behavior: A key factor for tourism planning

Tourism is a fast growing economic activity in many countries around the world. Many countries are promoting tourism to attract foreign tourists in a country. It has not only important but mandatory to acquire knowledge about tourist behavior. It would not be wrong to say that tourist behavior plays an important role in tourism planning. Due to the different geographical locations of continents, countries, people have different likes and dislikes, different behavior. On the other hand lack of knowledge about tourist behavior makes it arduous to promote tourism in a country. This paper aims at studying the Behavior of tourist and to help in the tourism planning in a country. This will help in promoting and selling tourism products

Coherent Pion Production in Neutrino Nucleus Scattering

In this article, we study the coherent pion production in neutrino-nucleus interaction in the resonance region using the formalism based on partially conserved axial current (PCAC) theorem which relates the neutrino-nucleus cross section to the pion-nucleus elastic cross section. The pion nucleus elastic cross section is calculated using the Glauber model in terms of pion-nucleon cross sections obtained by parameterizing the experimental data. We calculate the differential and integrated cross sections for charged current coherent pion production in neutrino carbon scattering. The results of integrated cross section calculations are compared with the measured data. Predictions for the differential and integrated cross sections for coherent pion productions in neutrino iron scattering using above formalism are also made
