Contribution by the Indian and Pakistani Authors to Library Philosophy and Practice: A Bibliometric Analysis 2008-2017.

A bibliometric analysis of the research papers explores different aspects of the contribution from an individual author to the country as a whole. The growth of publications, authorship patterns, paper lengths, referencing trends, prolific contribution of authors, etc. about a particular journal are includes in bibliometric studies. Keeping in mind the Indian contribution to a peer review e-journal namely Library Philosophy and Practice (e-Journal) this study began. Meanwhile, it is observed that already work has done on several related aspect. Further, it is also found that the same study has already conducted by Anwar, (2018), exploring the Pakistani contribution to the same journals from 2008-2017. Finally, the present study has designed to explore and compare the contribution of Indian and Pakistani authors to Library Philosophy and Practice (LPP) for a period of ten years from 2008-17. The India and Pakistan are two significant countries in South-East Asia those shares historical, political, and economic background together. This study is based on the bibliometric analysis on LPP covered a period from 2008-2017 in which 432 articles (86 articles from Pakistani & 346 articles from Indian authors) were published during the marked period. Study examines the various bibliometric parameters such as authorship pattern, geographical distribution, major authors, and length of articles. Study finds that 41.8% (181) articles were contributed by two authors. Further, the study found that 11-15 pages of articles published in majority by the authors in both countries

High dynamic range color image enhancement using fuzzy logic and bacterial foraging

High dynamic range images contain both the underexposed and the overexposed regions. The enhancement of the underexposed and the overexposed regions is the main concern of this paper. Two new transformation functions are proposed to modify the fuzzy membership values of under and the overexposed regions of an image respectively.For the overexposed regions, a rectangular hyperbolic function is used while for the underexposed regions, an S-function is applied. The shape and range of these functions can be controlled by the parameters involved, which are optimized using the bacterial foraging optimization algorithm so as to obtain the enhanced image. The hue, saturation, and intensity (HSV) color space is employed for the purpose of enhancement, where the hue component is preserved to keep the original color composition intact. This approach is applicable to a degraded image of mixed type. On comparison, the proposed transforms yield better results than the existing transformation functions17 for both the underexposed and the overexposed regions

3D Textured Model Encryption via 3D Lu Chaotic Mapping

In the coming Virtual/Augmented Reality (VR/AR) era, 3D contents will be popularized just as images and videos today. The security and privacy of these 3D contents should be taken into consideration. 3D contents contain surface models and solid models. The surface models include point clouds, meshes and textured models. Previous work mainly focus on encryption of solid models, point clouds and meshes. This work focuses on the most complicated 3D textured model. We propose a 3D Lu chaotic mapping based encryption method of 3D textured model. We encrypt the vertexes, the polygons and the textures of 3D models separately using the 3D Lu chaotic mapping. Then the encrypted vertices, edges and texture maps are composited together to form the final encrypted 3D textured model. The experimental results reveal that our method can encrypt and decrypt 3D textured models correctly. In addition, our method can resistant several attacks such as brute-force attack and statistic attack.Comment: 13 pages, 7 figures, under review of SCI

Effect of water depth, seedling age, and day length on elongation induced by short-duration flooding treatment in rice

Experiments conducted on seedling age and different water depths revealed that short-duration, 7-day flooding of 3 week- old seedling was effective in assessing elongation potential in deepwater rice varieties. Water depths of 90-100 cm were sufficient to express elongating ability and 3-week-old seedlings gave better contrast between elongating modern varieties and non-elongating modern varieties. Maximum internode length was under short-day-length conditions while shortest internodes were obtained in the long day treatment. Internode elongation may be due only to the signal effect of day length or the shading effect on assimilation. Further experiments should be conducted to confirm these findings

Studies on French Bean (Phaseolus vulgaris L.) Varieties under Different N, P, K and S Levels for Growth, Yield and Economics

Fifteen combinations of three French bean varieties viz., Arka Komal (V1), Swaran Priya (V2) and Contender (V3) and five fertilizer levels (F1- 20:40:40:20kg/ha NPKS; F2- 40:40:40:20kg/ha NPKS; F3 - 60:60:60:40kg/ha NPKS; F4 - 80:60:60:40kg/ha NPKS, and F5 -100:80:80:50kg/ha NPKS) were tested in factorial Randomized Block Design, with three replications. Among the varieties, Swaran Priya was superior for growth attributes, yield attributes and yield. Among fertilizer levels, F5 (100:80:80:50kg/ha NPKS) resulted in highest growth parameters, yield parameters and yield of pods. Economic evaluation showed that variety Swaran Priya under F5 (100:80:80:50kg/ha NPKS) resulted in maximum gross returns, net returns and cost:benefit ratio for green pod production

Biofuels Production from Biomass by Thermochemical Conversion Technologies

Agricultural biomass as an energy resource has several environmental and economical advantages and has potential to substantially contribute to present days’ fuel demands. Currently, thermochemical processes for agricultural biomass to energy transformation seem promising and feasible. The relative advantage of thermochemical conversion over others is due to higher productivity and compatibility with existing infrastructure facilities. However, the majority of these processes are still under development phase and trying to secure a market share due to various challenges, right from suitable infrastructure, raw material, technical limitations, government policies, and social acceptance. The knowledge at hand suggests that biomass can become a sustainable and major contributor to the current energy demands, if research and development are encouraged in the field of thermochemical conversion for various agricultural biomass types. This paper intends to explore the physical and chemical characteristics of biofuel substitutes of fossil fuels, potential biomass sources, and process parameters for thermochemical conversion

Spitzer/IRS Observations of Seyfert 1.8s and 1.9s: A Comparison with Seyfert 1s and Seyfert 2s

We present Spitzer Space Telescope mid-infrared spectra of 12 Seyfert 1.8 and 1.9 galaxies over the 5-38 um region. We compare the spectral characteristics of this sample to those of 58 Seyfert 1 and Seyfert 2 galaxies from the Spitzer archives. An analysis of the spectral shapes, the silicate 10 um feature and the emission line fluxes have enabled us to characterize the mid-IR properties of Seyfert 1.8/1.9s. We find that the equivalent widths of the 10 um silicate feature are generally weak in all Seyfert galaxies, as previously reported by several studies. The few Seyfert galaxies in this sample that show deep 10 um silicate absorption features are highly inclined and/or merging galaxies. It is likely that these absorption features originate primarily in the dusty interstellar medium of the host galaxy rather than in a dusty torus on parsec scales close to the central engine. We find that the equivalent width of the polycyclic aromatic hydrocarbon (PAH) band at 6.2 um correlates strongly with the 20-30 um spectral index. Either of these quantities are good indicators of the amount of starburst contribution to the mid-IR spectra. The spectra of Seyfert 1.8 and 1.9s are dominated by these starburst features, similar to most Seyfert 2s. They show strong PAH bands and a strong red continuum toward 30 um. The strengths of the high-ionization forbidden narrow emission lines [O IV] 25.89 um, [Ne III] 15.56 um and [Ne V] 14.32 um relative to [Ne II] 12.81 um are weaker in Seyfert 1.8/1.9s and Seyfert 2s as compared to Seyfert 1s. The weakness of high-ionization lines in Seyfert 1.8-1.9s is suggestive of intrinsically weak active galactic nuclei (AGN) continua, and/or stronger star formation activity leading to enhanced [Ne II]. We discuss the implications of these observational results in the context of the Unified Model of AGN.Comment: 36 pages, 4 tables, 6 figures, Accepted for publication in The Astrophysical Journal, December 200

Tropospheric distribution of sulphate aerosol mass and number concentration during INDOEX-IFP and its transport over the Indian Ocean: a GCM study

International audienceAn interactive sulphate aerosol chemistry module has been incorporated in the Laboratoire de Météorologie Dynamique General Circulation Model (LMD-GCM) to simulate the sulphur chemistry during the Indian Ocean Experiment (INDOEX) Intensive Field Phase-1999 (INDOEX-IFP). The originality of this module is its ability to predict particle mass and number concentration for the Aitken and accumulation modes. The model qualitatively reproduces the spatial patterns of observations on sulphate aerosol during INDOEX. On the basis of size distribution retrieved from the observations made along the cruise route during 1998 and 1999, the model successfully simulates the order of magnitude and the general north-south gradient in aerosol number concentration. The result shows the southward migration of minimum concentrations, which follows ITCZ (Inter Tropical Convergence Zone) migration. Sulphate surface concentration during INDOEX-IFP at Kaashidhoo (73.46° E, 4.96° N) gives an agreement within a factor of 2 to 3. Predicted sulphate aerosol optical depth (AOD) matches reasonably with measured values, indicating the capability of this model to predict the vertically integrated column sulphate burden. The Indian contribution to estimated sulphate burden over India is more than 60% with values upto 40% over the Arabian Sea
