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.

Institutional Vacuum in Sardar-Sarovar Project: Framing ‘Rules-of-the-Game’
No full textFew large irrigation projects in India have been as elaborately planned as the Sardar- Sarovar Project (SSP), incorporating as it did the lessons of decades of irrigation project design and management. The project was to blaze a new trail in farmer-participatory irrigation project design and management with water user associations (WUAs) building their own distribution systems. However, as it unfolds, the institutional reality of the project is seen to be vastly different from its plans. If SSP is to chart a different course from scores of earlier large irrigationprojects, it must invent and put into place new rules of the irrigation management game.Length: pp.95-106Irrigation programsRiver basinsGroundwater irrigationSurface irrigationWater users associationsWater allocation
Electronic structure and optical properties of Schiff base hydrazone derivatives by solution technique for optoelectronic devices: Synthesis, experiment and quantum chemical investigation
No full textWOS: 000449310600004In this study, electronic, optical and spectroscopic FT-IR, UV properties of new synthesized Schiff base hydrazone derivatives, 1-(4-nitrophenyl)-2-(4-phenoxybenzylidene)hydrazone and 1-(2,4-dinitropheny1)-2-(4-phenoxybenzylidene)hydrazone are investigated by performing solution techniques and theoretical calculations. Solvatochromism and solute-solvent interactions were discussed based on the spectral results. It is observed that Schiff base hydrazone derivatives exhibit positive solvatochromism. Energy band gap E-g is determined experimentally and theoretically in solution. Concentration effect on E-g was investigated in DCM solvent for different molarities of solute. It is observed that solvent and concentration can be used for tuning E-g. NO2 substituent group gives rise to E-g value lows 0.3 eV. The refractive index (n) values were obtained from Moss, Ravindra, Herve-Vandamme, Kumar-Singh and Reddy relations based on E-g data. It is observed that n can be controlled with solvents and concentration of solutions. External electric field (EF) is theoretically applied in order to tuning HOMO-LUMO gap and dipole moment. Consequently, Schiff base hydrazone derivatives intend to be insulator under applied EFBitlis Eren University, Research Foundation [BEBAP-2013.04, BEBAP-2014.05]; Bitlis Eren UniversityThe authors greatly appreciate Bitlis Eren University, Research Foundation for the financial support via BEBAP-2013.04 and BEBAP-2014.05 projects.

Charnockite formation at Ponmudi in Southern India
No full textCharnockites, constituents of most Precambrian high-grade terrains 1,2, are essential for understanding the evolution of the early continental crust. The arrested development of charnockite in shear veins at Kabbaldurga3, in the state of Karnataka in India, suggests flow of CO2-rich water-deficient fluids through deep-seated rocks as a mechanism of granulite grade metamorphism4,5. We report here an occurrence of arrested charnockite formation well south of Kabbaldurga, in the khondalite belt of southern Kerala, where rocks with amphibolite facies give way to the vast southern India-Sri Lanka charnockite terrain, indicating that metamorphism due to CO2-rich fluids (carbonic metamorphism) may have operated over a large area in southern India. If such localities prove to be widespread, the present level of exposure throughout much of the high-grade terrain probably does not extend far beyond an isofacial surface marking the boundary between upper and lower crust in the late Archaean. © 1985 Nature Publishing Group
Intense, ultrashort light and dense, hot matter
No full textThis article presents an overview of the physics and applications of the interaction of high intensity laser light with matter. It traces the crucial advances that have occurred over the past few decades in laser technology and nonlinear optics and then discusses physical phenomena that occur in intense laser fields and their modeling. After a description of the basic phenomena like multiphoton and tunneling ionization, the physics of plasma formed in dense matter is presented. Specific phenomena are chosen for illustration of the scientific and technological possibilities - simulation of astrophysical phenomena, relativistic nonlinear optics, laser wakefield acceleration, laser fusion, ultrafast real time X-ray diffraction, application of the particle beams produced from the plasma for medical therapies etc. A survey of the Indian activities in this research area appears at the end
OXPath: little language, little memory, great value.
No full textData about everything is readily available on the web-but often only accessible through elaborate user interactions. For automated decision support, extracting that data is essential, but infeasible with existing heavy-weight data extraction systems. In this demonstration, we present OXPath, a novel approach to web extraction, with a system that supports informed job selection and integrates information from several different web sites. By carefully extending XPath, OXPath exploits its familiarity and provides a light-weight interface, which is easy to use and embed. We highlight how OXPath guarantees optimal page buffering, storing only a constant number of pages for non-recursive queries. © 2011 ACM

No full textMultiple ionization of N<SUB>2</SUB> in intense, linearly and circularly polarized light fields
No full textThere are significant differences in the multielectron dissociative ionization (MEDI) of N2 by 100-fs-long laser pulses (intensity 1015W cm-2) using linearly and circularly polarized light, with substantial suppression of ionization in the latter case. Enhanced ionization occurs in both instances at an internuclear distance (r) of ∼2.2 Å, with an increased propensity for MEDI at larger r values with circularly polarized light
Effect of Tempering Temperature and Time on Strength and Hardness of Ductile Cast Iron
No full textThe use of ductile cast iron is as an engineering materials has been increase day by day. it is widely used in manufacturing industry. It have excellent combination of mechanical properties due to same heat treatment process at different time and temperature. It have an excellent combination of tensile strength, wear resistance, good corrosion resistance, good ductility, toughness, impact strength, by using different types of heat treatment process. The effects of tempering temperature and time on the mechanical properties of ductile cast iron is investigated in the current work. The all sample were austenitized at 900°C for 120 minutes and then quenched in mineral oil at room temperature. After quenching the specimens were tempered at 400°C and 200°C for 60min, 90min, and 120min, respectively. In the tempering temperature range of 200°C - 400°C, there is sudden increase in impact strength, ductility and toughness of the materials, as the temperature and time increase. The Ultimate tensile strength drops initially, and hardness of materials will also depends on amount of matrix phase of martensitic and retain- austenitic /ferrite and graphite nodules. In this work alloying elements also effected the microstructure of the specimen. And due to increase tempering time the amount of martensitic phase will decrease and austenitic phase will increase, austenitic phase is softer then martensitic so hardness will decrease. And sample treated to ball on plate wear tester under 20N load at constant speed 10rpm with different times 10min, 20min, 30min for sliding distance 4mm track diameter respectively of same sample. Weight loss was observed in all sample after wear test, the wear resistance was calculated according to the ASTM G 65 standard, and the result showed that in all cases, when the nodules count and nodularity increase the wear resistance decrease and when tempering time and temperature increase the wear resistance will also effected. And by XRD investigate the different matrix and volume fraction, peak analysis
