Twitter and Polls: Analyzing and estimating political orientation of Twitter users in India General #Elections2014
Abhishek Bhola
Computer Science , 2014,
Abstract: This year (2014) in the month of May, the tenure of the 15th Lok Sabha was to end and the elections to the 543 parliamentary seats were to be held. A whooping $5 billion were spent on these elections, which made us stand second only to the US Presidential elections in terms of money spent. Swelling number of Internet users and Online Social Media (OSM) users could effect 3-4% of urban population votes as per a report of IAMAI (Internet & Mobile Association of India). Our count of tweets related to elections from September 2013 to May 2014, was close to 18.21 million. We analyzed the complete dataset and found that the activity on Twitter peaked during important events. It was evident from our data that the political behavior of the politicians affected their followers count. Yet another aim of our work was to find an efficient way to classify the political orientation of the users on Twitter. We used four different techniques: two were based on the content of the tweets, one on the user based features and another based on community detection algorithm on the retweet and user mention networks. We found that the community detection algorithm worked best. We built a portal to show the analysis of the tweets of the last 24 hours. To the best of our knowledge, this is the first academic pursuit to analyze the elections data and classify the users in the India General Elections 2014.
Smart Grid, Smart Controllers and Home Energy Automation—Creating the Infrastructure for Future  [PDF]

Smart Grid and Renewable Energy (SGRE) , 2012, DOI: 10.4236/sgre.2012.33024
Abstract: Integration of unpredictable renewable power sources into the Grid is leading to the development of wide area control algorithms and smart grid. Smart meters are the first step in the building a smart consumer interface. Much more, however, would be required in building a smart grid than just smart meters. This paper explores the conceptual architecture of smart grid. It highlights the need for additional infrastructure to realize full potential of smart grid. The information presented in this paper is an attempt to uncover what the future in smart grid could be and what infrastructure would be required to tap its potential. As smart grid evolves, more functionality would be built in the constituents. The paper also proposes mathematical basis for some of the controller algorithms.
Consumption Value of Digital Devices: An Investigation through Facebook Advertisement  [PDF]
Abhishek Mishra
Social Networking (SN) , 2015, DOI: 10.4236/sn.2015.43007
Abstract: Data collection represents the most effort-intensive stage of any marketing research exercise, especially in cases sampling frame is unavailable. Sub-optimal bypasses in form of student surveys or surveys employing convenience sampling have become common. In modern era, where laptops and smartphones enable easy accessibility of respondents online, this study utilizes Facebook advertisement as a source of data collection to measure the construct of user experience for interactive products. Modern digital devices, like smartphones, are a source of a variety of experiences for the user. Design teams at various smartphone manufacturers are struggling every day to create products which provide complete consumer experiences. This work not only proposes a framework for describing the same with usability, social value and pleasure in use, but also tests the scales for each by empirical validation. Data collection process through Facebook, as a sample frame, is something yet to be seen in marketing literature. This work goes the distance in not only demonstrating the efficacy of using Facebook advertisement as a viable data collection tool but also developing a framework to measure consumption value. Outcomes of the study, should promote further research using this sampling frame for future research, especially in the area of marketing.
Study on the use of tobacco among male medical students in Lucknow, India
Kumari Ranjeeta,Nath Bhola
Indian Journal of Community Medicine , 2008,
Abstract: Objectives: Is use of tobacco a major health problem among medical students? To find out the factors associated with the use of tobacco. Materials and Methods: A cross-sectional study was done on 250 undergraduate male medical students using a pre-designed, pre-tested questionnaire to study about the problem and various correlates of the tobacco use. Data was collected and analysed using Excel and SPSS software. Results: Among the tobacco users (28.8%), smoking was found in 87.5% and tobacco chewing in the form of gutka, khaini, gulmanjan (locally available forms of tobacco) in 37.5% as the predominant means of the use of tobacco. The mean age of our sample was 23.5 years. The residential background, i.e., rural or urban, and religion were not significantly associated with the use of tobacco in the present study. Hostellers were found to be more frequent tobacco users as compared to day-scholars. There was a familial aggregation of the use of tobacco. The factor initiating the use of tobacco was usually peer pressure. Conclusion: Tobacco use is a significant problem among the male medical students and we need to take steps to stop its use by them so as to prevent them from being exposed to its hazardous effects. This will also make their role in the advocacy of the smoking cessation activities more trustworthy.

Electrochemical Behavior of Titanium and Its Alloys as Dental Implants in Normal Saline
Rahul Bhola,Shaily M. Bhola,Brajendra Mishra,David L. Olson
Advances in Physical Chemistry , 2009, DOI: 10.1155/2009/574359
Abstract: The electrochemical behavior of pure titanium and titanium alloys in a simulated body fluid (normal saline solution) has been tested, and the results have been reported. The significance of the results for dental use has been discussed. The tests also serve as a screening test for the best alloy system for more comprehensive long-term investigations.

Discovery of the Sun's million-degree hot corona
H. Peter,Bhola N. Dwivedi
Frontiers in Astronomy and Space Sciences , 2014, DOI: 10.3389/fspas.2014.00002
Abstract: As time goes by, discoveries become common knowledge, and often the person who first changed a paradigm gets forgotten. One such case is the discovery that the Sun's corona is a million degrees hot—much hotter than its surface. While we still work on solving how the Sun heats the corona, the name of the discoverer seems to be forgotten. Instead, other people get the credit who contributed important pieces to the puzzle, but the person who solved this puzzle was someone else. In this historical note we show that this credit should go to Hannes Alfvén (cf. Figure 1).
On the gravitational redshift
Klaus Wilhelm,Bhola N. Dwivedi
Physics , 2013, DOI: 10.1016/j.newast.2014.01.012
Abstract: The study of the gravitational redshift\,---\,a relative wavelength increase of $\approx 2 \times 10^{-6}$ was predicted for solar radiation by Einstein in 1908\,---\,is still an important subject in modern physics. In a dispute whether or not atom interferometry experiments can be employed for gravitational redshift measurements, two research teams have recently disagreed on the physical cause of the shift. Regardless of any discussion on the interferometer aspect\,---\,we find that both groups of authors miss the important point that the ratio of gravitational to the electrostatic forces is generally very small. For instance, the gravitational force acting on an electron in a hydrogen atom situated in the Sun's photosphere to the electrostatic force between the proton and the electron is approximately $3 \times 10^{-21}$. A comparison of this ratio with the predicted and observed solar redshift indicates a discrepancy of many orders of magnitude. Here we show, with Einstein's early assumption of the frequency of spectral lines depending only on the generating ion itself as starting point, that a solution can be formulated based on a two-step process in analogy with Fermi's treatment of the Doppler effect. It provides a sequence of physical processes in line with the conservation of energy and momentum resulting in the observed shift and does not employ a geometric description. The gravitational field affects the release of the photon and not the atomic transition. The control parameter is the speed of light. The atomic emission is then contrasted with the gravitational redshift of matter-antimatter annihilation events.
