Cloud computing provides dynamic provisioning, that is applied not only to services, but also to compute capability, storage, networking and infrastructure in general. Resources are made available through internet and offered on a pay-per-use basis. Parallel processing applications consists of multiple active tasks simultaneously solving a problem. These tasks are allocated to different processors. All the parallelism approaches have a goal to improve processor efficiency by reducing latency. To reduce latency, there must be another thread ready to run whenever a lengthy operation occurs. It executes more single threaded applications in a concurrent manner. In particular parallelism is used to process multiple jobs together so that the system can increase its performance. The parallel scheduling algorithm has to schedule the jobs in an effective so as to reduce the execution time and increase the resource utilization, thereby improving performance of the system. Experimental results show that proposed algorithms exhibit good performance under heavy loads and show a considerable improvement in the utilization of resources.

Due to the wide extension of power electronics equipment in modern electrical systems, the increase of the harmonics disturbance in the alternating currents has became a major concern due to the adverse effects on all equipments. The equipment will develop harmonic pollution source of the system, which generate many disturbances, and interrupt the optimal operation of electrical equipments. These equipments draw non-linear currents from the source as compare to traditional loads such as motors and resistive heating elements. This work, proposed a solution to eliminate the harmonics introduced by the nonlinear loads. The analysis and simulation using Matlab Simulink of active power filter (SAPF) compensating the reactive power and harmonics produced by nonlinear loads in steady and in transients states. Hence the simulation approach for SAPF is used to diminish the harmonics and gives improved power factor with reduced THD using Mat lab Simulink in order to develop new fuzzy logic controller based SAPF. © 2016 IEEE.

In this paper, the graph theory has been developed into an extensive and popular branch of mathematics, which in turn has been applied to many problems in semicarbazone and thiosemicarbazone compounds. The compounds such as N-hydroxy-2,6-bis(pchlorophenyl)-3-isopropylpiperidin-4-one semicarbazone and N-hydroxy-2,6-bis(p-chlorophenyl)-3-isopropylpiperidin-4-one thiosemicarbazone have been synthesised and characterised on the basis of elemental analysis such as 1H NMR and 13C NMR. Several open problems that have gained respect with the help of graph theory, which can be recorded through simple, finite, connected and undirected group. The compounds which have been synthesised can be split into four sub groups. Each subset has been defined such as alkyl by graceful tree graph, N-hydroxy ring and phenyl compounds by non-graceful graph and semicarbazone and thiosemicarbazone by cliques representations of graph. The compound has been represented mathematically in terms of -p vertices and -q cliques. A complete picturisation of the compounds by combining all the subgroups together has been schematically icono-graphed. Copyright © 2017 Inderscience Enterprises Ltd.

A series of 3-ethyl-2,6-diarylpiperidin-4-one semicarbazone and 3,5-dimethyl-2,6-diarylpiperidin-4-one semicarbazone were synthesised. The semicarbazones were subjected to cyclic voltammetric analysis using glassy carbon electrode with variable scan rate. The method involves electron transfer without the use of oxidising or reducing agents. The study of cyclic voltammogram showed that all the compounds have undergone irreversible reduction. The peak potential values, the number of peaks formed during the anodic and cathodic scan and the different scan rate used have established irreversible reduction reaction. The reduction products were isolated and purified by column chromatography. The structure is proved by 1H and 13C NMR spectroscopy. Further five products were analysed for anti bacterial activity and the nitro substituted compound showed a high inhibition towards Salmonella typii among the eight bacterial cultures.

Optical networks pose real difficulty in finding the flexible optical routing path for high speed data transmission in optical communication network environment because of critical path, blocking performance, and security; processing delay, etc., to overcome this pitfall, a new algorithm fuzzy graph based ranking has been proposed. In this algorithm contain two schemes that are: fuzzy and graph theory, for this work we consider the distance and processing time, these two parameters are represented by fuzzy numbers and fuzzy triangular numbers, those values are used to find the shortest path from the different paths. In this paper observed that fuzzy graph based alternate routing scheme provided for better routing performance. In addition to that, the simulated results show that the network, performance can be improved when alternative routes are used in optical router architecture and also illustrate the numerical example of shortest path and fuzzy graph theory has been surveyed. The definite architecture for optical router and analytical approach is given in this paper, It helps that the researchers to improve the optical routing capabilities according to the fulfillment of present needs better analysis and simulation report shows that proposed method provides an optimized route in the optical network over the existing algorithms. The objectives of this paper, to minimize the processing delay of finding the shortest path (optimum path) and attain higher throughput. © 2017, Springer Science+Business Media, LLC.

This research paper provides a new platform for the graph labelling method of 3-isobutyl-2,6bis(m-nitrophenyl)-piperidin- 4-one semicarbazone. A futuristic approach for the synthesised compound has been developed in the graph theory and sequence of reaction mechanism of compound is done through complete tripartite graph accepting continuous monotonic decomposition concepts. In the same way we have desired functional illustration and acceptance of graph theory to chemistry dictionary. Thus the complex compound is enhanced in mathematical theory to correlate the mode of arrangement of compound in graph labelling. The focus of this application is to bridge the qualitative relationship and representation of research compound in graphical decomposition factors. © 2017 NSP, Natural Sciences Publishing Cor.

In the title compound, C18H19BrN2O 4, the chromene unit is not quite planar (r.m.s. deviation = 0.199Å), with the methyl C atoms lying 0.027(4) and 1.929(4)Å from the mean plane of the chromene unit. The six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation, with the dimethyl-substituted C atom as the flap. The methylamine and nitro groups are slightly twisted from the chromene moiety, with C - N - C - O and O - N - C - C torsion angles of 2.7(4) and -0.4(4)°, respectively. The dihedral angle between the mean plane of the chromene unit and the benzene ring is 85.61(13)°. An intramolecular N - H⋯O hydrogen bond generates an S(6) ring motif, which stabilizes the molecular conformation. In the crystal, molecules are linked via N - H⋯O hydrogen bonds, forming hexagonal rings lying parallel to the ab plane. A region of disordered electron density, most probably disordered ethanol solvent molecules, occupying voids of ca 432Å3 for an electron count of 158, was treated using the SQUEEZE routine in PLATON [Spek (2009). Acta Cryst. D65, 148-155]. Their formula mass and unit-cell characteristics were not taken into account during refinement. © 2014 CrossMark.
