No full textMegalithic monuments are found all over the Indian subcontinent, though the vast majority of
these are distributed in peninsular India, with sparser distribution in the north (Moorti 1994,
2008; Brubaker 2001). Though generally ascribed to the south Indian Iron Age (Moorti 1994,
2008; Sundara 1975), their origins could well go back to the Neolithic, and megalith construction
might have lasted into the Early Historic period (Morrison 2005, 2009, Menon 2012a, 2012b).

Architecture and security issues in fog computing applications Advances in computer and electrical engineering (ACEE) book series./ [edited by] Sam Goundar, S. Bharath Bhushan, Praveen Kumar Rayani.
No full textIncludes bibliographical references and index.As the progression of the internet continues, society is finding easier, quicker ways of simplifying their needs with the use of technology. With the growth of lightweight devices, such as smart phones and wearable devices, highly configured hardware is in heightened demand in order to process the large amounts of raw data that are acquired. Connecting these devices to fog computing can reduce bandwidth and latency for data transmission when associated with centralized cloud solutions and uses machine learning algorithms to handle large amounts of raw data. The risks that accompany this advancing technology, however, have yet to be explored. Architecture and Security Issues in Fog Computing Applications is a pivotal reference source that provides vital research on the architectural complications of fog processing and focuses on security and privacy issues in intelligent fog applications. While highlighting topics such as machine learning, cyber-physical systems, and security applications, this publication explores the architecture of intelligent fog applications enabled with machine learning. This book is ideally designed for IT specialists, software developers, security analysts, software engineers, academicians, students, and researchers seeking current research on network security and wireless systems.1.

Fulgoraecia melanoleuca Fletcher
No full textFulgoraecia melanoleuca (Fletcher) Epipyrops melanoleuca Fletcher, 1939: 293; Kato, 1940: 79. Epiricania melanoleuca (Fletcher); Misra & Krishna, 1987; Khan & Kanhaya, 1988; Ansari et al., 1989; Joshi & Sharma, 1989. See Nomenclatural note below. Fulgoraecia melanoleuca (Fletcher); Beccaloni et al., 2003. Nomenclatural note. Several authors have used the combination Epiricania melanoleuca (see above). Yet we have been unable to find any published reference where the transfer of melanoleuca to Epiricania was formally done. Kato (1940: 79) described the genus Epiricania, but on page 83 of the same work he listed melanoleuca under Epipyrops. Davis (1983: 67) treated Epipyrops Bowring, 1876 as a junior synonym of Fulgoraecia Newman, 1851. But according to Nye & Fletcher (1991), because the senior name has not been used since it was established, the existing usage of the junior name should be maintained and the case referred to the International Commission of Zoological Nomenclature. Here we follow the online Lepindex (Beccaloni et al. 2003) in using the combination Fulgoraecia melanoleuca. Morphology. Adults (Fig. 1, 7– 8): Both males and females can be easily distinguished as adults. In the male the outer margin of the forewing is off white and the hindwing off white, while in female the forewing is grey black and the hindwing dark grey. The antennae are bipectinate in both sexes and the wing expanse is 9–12 mm in the male and 10–13 mm in the female. The newly emerged female does not fly well whereas males are active and fly rapidly in search of females for coupling. The coupling time noted under field conditions is 10–15 minutes. Eggs (Fig. 2): The female begins oviposition immediately and lays upto 234– 450 eggs. The eggs are light brown in color (Fig. 2) and are mostly laid on the leaf margin near to the cocoon. After hatching, only three larval instars develop. Larva (Figs. 3 -5, 9– 13): Larvae possess a proboscis-like structure (Fig. 11), which functions in sucking fluid from the abdomen of the host’s abdomen (P. perpusilla). Four pairs of abdominal and one pair of anal prolegs are present. Abdominal prolegs have uniordinal, uniserial crochets. Anal proleg with crochets uniserial but in a half circle, which help to attach to the abdomen of the host (Davis 1987). The body of larvae is covered with white waxy material. Cocoons (Figs. 6, 14– 21): Cocoons are constructed on the leaf, and are pure white, elongate, flattened, convex anteriorly and concave posteriorly. Male and female pupae are light brown. Male pupae have a short abdomen and the male genital scar is present on the 9 th sternum. Female pupae are larger than male pupae and with a larger abdomen. Eight and 9 th sternum are fused and a female genital pore is present on the fused sternum. The anus is present on the 10 th sternum in both male and female pupa. Dark brown color patches are present on the dorsal surface of female pupal abdominal segments, and fewer light brown patches are present on all dorsal surfaces of male pupal abdominal segments.

Nonlinear Vibration and Instability of a Randomly Distributed CNT-Reinforced Composite Plate Subjected to Localized In-plane Parametric Excitation
No full textThis study presents a semi-analytical formulation for the nonlinear vibration and dynamic instability of a randomly distributed carbon nanotube-reinforced composite (RD-CNTRC) plate. Three cases of localized in-plane periodic loadings are studied. The analytical stress fields within the RD-CNTRC plate for all the in-plane stress components (σij, (i, j = x, y)) are developed by solving the in-plane elastic problem using Airy's stress approach. The effective mechanical properties of the RD-CNTRC plate are evaluated by the Eshelby-Mori-Tanaka technique. The plate is modeled based on higher-order shear deformation theory (HSDT) in conjunction with the von-Kármán nonlinearity. Using Hamilton's principle, the governing partial differential equations (PDEs) are derived, whose approximate solution is sought, referring to the Galerkin method. The resulting nonlinear ODEs are solved using the Incremental Harmonic Balance (IHB) Method to compute the nonlinear vibration response of the RD-CNTRC plate. Further dropping the nonlinear terms, these ODEs are solved by Bolotin's method to trace the instability region. The proposed semi-analytical method is an effective strategy for studying the influence of different parameters such as agglomeration models, CNT mass fraction, pre-loading, and boundary conditions on the nonlinear vibration and dynamic instability characteristics of the RD-CNTRC plates. The reduced computational effort allows the design phase to be supported in selecting parameters when designing RD-CNTRC plates with stability and vibration requirements

Estimate of etched tracks by optical method and spark counting
No full textSolid State Nuclear Track Detectors (SSNTD) are commonly used for long
term measurements of radon, thoron and progeny concentrations. In the present study,
we compared the optical counting method and the spark counting technique for
counting the alpha tracks on LR 115 track detector films. The paper discusses the
various parameters that are innate in the process. More than 300 films were counted
by both optical microscope and spark counter and the results are compared. The
overall results show that the tracks obtained by spark counting are marginally less
compared to the optical measurement. A linear fit of the data gives a slope less
that one, which indicates that both the methods are almost in good agreement for
counting the tracks when the track density is low. At higher track densities the
spark counter gives an underestimation with respect to actual number of tracks
formed, which could be corrected using a relation obtained between the tracks
measured by optical method and spark counting.Estimate of etched tracks by optical method and spark counting

Bollywood cinema: A critical genealogy
No full text"Bollywood" has finally made it to the Oxford English Dictionary. The 2005 edition defines it as: "a name for the Indian popular film industry, based in Bombay. Origin 1970s. Blend of Bombay and Hollywood." The incorporation of the word in the OED acknowledges the strength of a film industry which, with the coming of sound in 1931, has produced some 9,000 films. (This must not be confused with the output of Indian cinema generally, which would be four times more). What is less evident from the OED definition is the way in which the word has acquired its current meaning and has displaced its earlier descriptors (Bombay Cinema, Indian Popular Cinema, Hindi Cinema), functioning, perhaps even horrifyingly, as an "empty signifier" (Prasad) that may be variously used for a reading of popular Indian cinema. The triumph of the term (over the others) is nothing less than spectacular and indicates, furthermore, the growing global sweep of this cinema not just as cinema qua cinema but as cinema qua social effects and national cultural coding. Although Indian film producers in particular, and pockets of Indian spectators generally, continue to feel uneasy with it (the vernacular press came around to using "Bollywood" only reluctantly), its ascendancy has been such that Bombay Dreams (the Andrew Lloyd Weber musical) and the homegrown Merchants of Bollywood both become signifiers of a cultural logic which transcends cinema and is a global marker of Indian modernity. As the Melbourne (March 2006) closing ceremony of the Commonwealth Games showed, Bollywood will be the cultural practice through which Indian national culture will be projected when the games are held in Delhi in 2010. International games (the Olympics, World Cup Soccer, Asian Games, Commonwealth Games, and so on) are often expressions of a nation's own emerging modernity. For India that modernity, in the realm of culture, is increasingly being interpellated by Bollywood
