We propose a cloud based storage defragmentation technique in this paper. The cloud based defragmentation technique exhibits parallel concept of defragmentation. The proposed cloud based defragmentation technique involves defragment storage with less time consumption. Time graph is used to analyse memory access time using cloud based defragmentation technique. The comparisons have been depicted in time graph. © 2016 IEEE.

The main contribution of this article is to investigate the application suitability of Cellular Automata based pseudo-random noise generator in Code Division Multiple Access Communications. New dynamics in group Cellular Automata were explored. Extensive analysis for two classes of group Cellular Automata (maximum length Cellular Automata and equal length Cellular Automata) were carried out. The analysis and comparison results for these classes of group Cellular Automata demonstrate the advantages of equal length Cellular Automata over maximum length Cellular Automata in view of code division multiple access applications. © 2017, All Rights Reserved.

In this paper we calculate the energy distribution of the Mu-in Park, Kehagias-Sfetsos and Lü, Mei and Pope black holes in the Hořava-Lifshitz theory of gravity. These black hole solutions correspond to the standard Einstein-Hilbert action in the infrared limit. For our calculations we use the Einstein and Møller prescriptions. Various limiting and particular cases are also discussed. © 2011 Springer Science+Business Media, LLC.

In this paper, we study the thermodynamics of black holes using a generalized uncertainty principle (GUP) with a correction term linear order in the momentum uncertainty. The mass-temperature relation and heat capacity are calculated from which critical and remnant masses are obtained. The results are exact and are found to be identical. The entropy expression gives the famous area theorem upto leading order corrections from GUP. In particular, the linear order term in GUP leads to a √A correction to the area theorem. Finally, the area theorem can be expressed in terms of a new variable termed as reduced horizon area only when the calculation is done to the next higher order correction from GUP. © 2014 Springer Science+Business Media New York.

A novel approach has been introduced in this paper to detect and avoid black hole nodes during formation of reliable path for wireless data transmission. A valid acknowledgement is transmitted to the data packet sending node and its predecessor connected node. A trusted routing table created with valid acknowledgement receiver node. Secure data transmission is dependent upon the trusted routing table. Black hole nodes are required to be discarded from the data transmission. The information about the black hole node is broadcasted to the other nodes of the network to eliminate the uses of false route declaration. © 2015 IEEE.

Glass of composition SiO2-Al2O3-CaO- CaF2 (SACF) was made by conventional melting and quenching process using either normal or nano-SiO2. The glasses were characterized by differential thermal analysis (TG/DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM) and EDAX. The crystallization, microstructure, mechanical and chemical properties were compared for the two systems. It was observed that the nano silica containing glass ceramic have lower crystallization peak temperature (Tp), higher Vickers hardness and acid resistance than that of normal silica containing glass ceramics. © 2013 AIP Publishing LLC.

We provide a new type of thin-shell wormhole from the black holes with dilaton and monopole fields. The dilaton and monopole that built the black holes may supply fuel to construct the wormholes. Several characteristics of this thin-shell wormhole have been discussed. Finally, we discuss the stability of the thin-shell wormholes with a "phantom-like" equation of state for the exotic matter at the throat. © 2011 Springer Science+Business Media, LLC.

Photoinduced interactions of 9-aminoacridine hydrochloride hydrate (9AA-HCl) with aromatic and aliphatic amines, N,N'-dimethylaniline (DMA) and triethylamine (TEA) respectively have been investigated in homogeneous water-acetonitrile (1:1) mixture as well as in heterogeneous cetyltrimethyl ammonium bromide (CTAB) micellar media using UV-vis absorption, steady-state as well as time-resolved fluorescence spectroscopies and laser flash photolysis technique associated with a weak external magnetic field (MF). Differential modes of fluorescence quenching of 9AA-HCl with DMA and TEA corroborated with absorption studies reveal their disparity in the mechanism of interactions. Excited state proton transfer (ESPT) and photoinduced electron transfer (PET) are the phenomenon that have been found to be involved in with DMA, whereas with TEA ground-state complex formation, ground-state proton transfer and PET are prevalent. Discrepancy in pH of the interfacial and hydrophobic regions of CTAB facilitates the partitioning of the protonated and neutral forms of 9AA-HCl leading to differential occupational sites of the acceptor and donor moieties in the micellar medium, thus making the study more intriguing. Another important aspect of the present study is the use of MF to confirm the occurrence of PET, authenticate the spin-state of the intermediates thus formed and also to resolve the process of PET and ESPT. © 2014 Elsevier B.V.

We study the Schwarzschild and Reissner-Nordström black hole thermodynamics using the simplest form of the generalized uncertainty principle (GUP) proposed in the literature. The expressions for the mass-temperature relation, heat capacity and entropy are obtained in both cases from which the critical and remnant masses are computed. Our results are exact and reveal that these masses are identical and larger than the so called singular mass for which the thermodynamics quantities become ill-defined. The expression for the entropy reveals the well known area theorem in terms of the horizon area in both cases upto leading order corrections from GUP. The area theorem written in terms of a new variable which can be interpreted as the reduced horizon area arises only when the computation is carried out to the next higher order correction from GUP. © 2014 Springer Science+Business Media New York.
