Cloud computing is a scattered computing prototype which permits a third party to offer accomplished computer possessions in an on-bidding manner for people to track their own services. The supplier manages this by dynamic huge data centers of service computers, obligatory the economies of calibration to accusation its users for each unit usage time. So, in an approach, it is computer dealings. In Cloud Computing now a day's having more cloud applications. In the standard environment, the service vitality, elasticity, choices and flexibility suggest by this scalable technology are too attractive that makes the cloud computing to increasingly becoming a necessary part of the enterprise computing environment. Cloud computing facilities allow users to lease computing possessions from huge scale data centers operated by cloud service suppliers. Applying the cloud services, users can use a varied variety of applications enthusiastically and on-demand. In this paper explains about the features and survey of Dropbox and Google Drive in the real world. © Research India Publications. Source

In this paper, we construct a discrete-time predator-prey model. Our predator- prey model includes carrying capacity for both the predator and prey populations. This would represent some limitation on the predator and prey populations. The carrying capacity is the size of the population that can be supported indefinitely upon the available resources. We compare the stability of the discrete-time predator–prey system with and without Allee effect. And then we exhibit the impact of the Allee effect on the stability when it is imposed on the prey population. © Research India Publications. Source

Green synthesis of silver nanoparticles (AgNPs) using Hybanthus enneaspermus extract at room temperature that act as a reducing agent as well as capping agent has been investigated. The synthesized AgNPs were characterized by UV–visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FTIR), zeta potential, and dynamic light scattering (DLS) transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX). The silver surface plasmon resonance was observed at 420 nm in the UV–visible spectrum. XRD peaks were observed at 2θ values in 38.20°, 44.40°, 64.60°, and 77.50° which are indexed as (111), (200), (220), and (311) bands of face-centered cubic (fcc) structures of silver. FTIR revealed the AgNPs were capped with plant compounds of alcohol, phenols, carbonyl, amines, and amide functional groups. TEM image shows that the particles were of spherical, hexagonal, and triangular in shape, and the size range was 16–26 nm. Further, DLS exhibits the average size of 25.2 nm and the zeta values were measured (−27.1 mV) which proves the stability of the AgNPs. The conversion of Ag+ ions into Ag0 was calculated using inductively coupled plasma atomic emission spectroscopy (ICP-MS) and was found to be 96 %. The biosynthesized AgNPs showed the larvicidal activity with the LC50 values of 17.24 and 13.12 mg/L against the fourth-instar larvae of Anopheles subpictus and Culex quinquefasciatus, respectively. The GC-MS analysis of the plant extract showed that 39 bioactive phytochemical compounds have been found to possess a wide range of activities, which may help in the protection against incurable diseases. © 2015, Springer-Verlag Berlin Heidelberg.

Advances in Fuzzy Systems

In problems of graphs involving uncertainties, the fuzzy shortest path problem is one of the most studied topics, since it has a wide range of applications in different areas and therefore deserves special attention. In this paper, algorithms are proposed for the fuzzy shortest path problem, where the arc length of the network takes imprecise numbers, instead of real numbers, namely, level λ-triangular LR fuzzy numbers. Few indices defined in this paper help to identify the shortest path in fuzzy environment. ©2012 S. Elizabeth and L. Sujatha. Source

This paper deals with quantification of the noise located in the digital signal by an innovative process. This process is associated with the filter that represents the novel information conveyed by the desired signal, residual interference and residual noise which are used to reduce the noise. A typical uniform quantization operation of a sampled signal is identified and interpreted with the framework of stochastic difference equation. A new theorem is proposed with all possible assumptions to support our result to signal noise ratio. © (2014) Trans Tech Publications, Switzerland. Source
