Content based data retrieval on KNN- classification and cluster analysis for data mining

Data mining is sorting through data to identify patterns and establish relationships.Data mining parameters include: Regression - In statistics, regression analysis includes any techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables. Sequence or path analysis - looking for patterns where one event leads to another later event. Classification - looking for new patterns. Clustering - finding and visually documenting groups. Decision Trees 2013; Decision trees are commonly used in operations research, specifically in decision analysis, to help identify a strategy most likely to reach a goal

Fixed Mobile Convergence a IMS Approach

The paper is aimed at studying and analyzing the network performance parameters of SIP protocol. SIP is content based protocol, in which various message are required to be transacted so that a session could be created, terminated or modified. Therefore, the objective is to analyze various SIP activities and the delay incurred in session start-up under various network conditions. Proper functioning of IMS platform is dependent on optimum performance of several protocols specified in the standard. Nearly all of the protocols used in IMS are standardized by the IETF. Some of the major protocols are SIP, SDP- signaling protocol, DIAMETERimprovised version of RADIUS protocol,COPS- Common Open Policy Service, H.248- descendant of MEGACo, RTP/RTCPReal Time Protocol/Real Time Control Protocol, etc. Out of all these, Session Initiation Protocol (SIP) is the prominent protocol used to create, terminate and modify the sessions initiated by the user. In order to improve the performance parameters, this is the area where most of the research work is centralized. Hence, to study various aspects of SIP protocol with respect to the network performance is of great interest

“STRUCTURAL PROPERTIES OF HOLMIUM DOPED COBALT FERRITE BY STANDARD CERAMIC TECHNIQUE”

Objective: Compositions of CoHoxFe2-xO4 (x = 0.00 and 0.02) was prepared by standard ceramic technique using AR grade CoO2, Ho2O3 and Fe2O3. The samples were characterized by X-ray diffraction technique and the analysis of XRD patterns reveals the formation of single phase cubic spinel structure. The structural parameters like lattice constant (a), x- ray density(dx), bulk density (dB), particle size (t) and porosity (P), tetrahedral and octahedral bondlength (dAX and dBX), the tetrahedral edge (dAXE), and the shared and unshared octahedral edge (dBEX and dBXEU) can be calculated were calculated form XRD data and effect of Ho3+ doped cobalt ferrite was studied. Thus, the rare earth Ho3+ doped cobalt ferrite strongly influences the physical properties of cobalt ferrite. Materials and Methods: Present series was prepared by standard ceramic technique using AR grade CoO2, Ho2O3 and Fe2O3. Results: The XRD pattern shows that both the samples possess single phase cubic spinel structure. No extra peak of Ho3+ is observed for x =0.02 sample. Lattice constant, X-ray density of Ho3+ doped cobalt ferrite is increases than that of pure cobalt ferrite. Conclusion: The rare earth Ho3+ doped cobalt ferrite strongly influences the physical properties of cobalt ferrite

ELECTRICAL CONDUCTION, dielectric BEHAVIOR AND MAGNETOELECTRIC EFFECT IN (1-x) Co1.2Mn0.2Fe1.6O4 + (x) BaTiO3 ME Composites

Objective: Electrical and magnetoelectric properties of magnetoelectric (ME) composites ferroelectric as electric component and a mixed ferrite as magnetic component are reported. The (1-x) Co1.2Mn0.2Fe1.6O4 + (x) BaTiO3 magnetoelectric (ME) composite have been prepared using conventional double sintering ceramic process where x varies as 0.00, 0.25, 0.50, 0.75 and 1.00. The X-ray diffraction pattern of the composites reveals the formation of spinel structure for the piezomagnatic phase and tetragonal perovskite structure for the piezoelectric phase without any other phase formation. The dc resistivity was measured as a function of temperature. The variation of dielectric constant ' dielectric loss ε'' and dielectric loss tangent δ with frequency in the range 1kHz-1MHz was studied. The dielectric constant shows dispersion in the lower frequency region, with almost a constant value at higher frequencies. The magnetoelectric voltage coefficient (dE/dH)H was studied as a function of intensity of the magnetic field. The measured magnetoelectric (ME) response demonstrated strong dependence on the volume fraction of CoMnFe2O4 and the applied magnetic field. A large ME voltage coefficient of about 647 Vcm-1Oe-1 was observed for 25% CoMnFe2O4 + 75% BaTiO3composite. Materials and Methods: The piezoelectric phase Barium Titanate (BaTiO3) was prepared by standard doubling sintering ceramic method using AR grade oxides/carbonate. Barium carbonate (BaCO3) and Titanium-dioxide (TiO2) were taken in molar proportion. Results: The electrical resistivity of ferrite phase is less as compared to the resistivity of ferroelectric material. The resistivity of composites is found to be in between ferrite and ferroelectric. Conclusion: Magneto-electric conversion factor with varying magnetic field shows maxima in the curve at a lower magnetic field and then decreases continuously at higher magnetic field. As ferroelectric content increases both the resistivity and magnetoelectric conversion factor also increases

Design and development of microemulsion drug delivery system of atorvastatin and study its intestinal permeability in rats

The objective of this study was to design and develop microemulsion drug delivery system of Atorvastatin and to investigate its intestinal transport behavior using the single-pass intestinal perfusion method in rat. Microemulsion drug delivery system of Atorvastatin was prepared by water titration method and optimized formulation was characterized. The permeability behavior of Atorvastatin over three different concentrations (10, 20 and 40 μg/mL) was studied in each isolated region of intestine (i.e. duodenum, jejunum, ileum and colon) of rat by single-pass intestinal perfusion method in rat method at a flow rate of 0.2 ml/min. The concentration of the sample was determined by HPLC and the effective permeability coefficients were calculated. Considering the high correlation of rat permeability coefficient values with those of human, the human intestinal permeability was predicted using the Lawrence compartment absorption and transit model. The intestinal permeability of Atorvastatin in microemulsion, plain drug suspension and marketed formulation was also compared. The particle size and zeta potential of Atorvastatin microemulsion were (18.2±0.3) nm and (–9.19±0.8) mV respectively. There was no significant difference in permeability coefficient in jejunum, duodenum and ileum with same concentration but higher in colon was observed. The permeability coefficient in jejunum at 10 μg/mL was significantly higher than that at 40 μg/mL (p< 0.01). The estimated human intestinal permeability of Atorvastatin for the microemulsion was relatively higher. Based on the above results, it could be concluded that microemulsion formulation could enhance the intestinal permeability of Atorvastatin and thus could be presented as a possible alternative to traditional oral formulations for improving the oral absorption of Atorvastatin.Keywords: Microemulsion;, Zeta potential; Atorvastatin; Single-pass intestinal perfusion (SPIP) method; Compartment absorption and transit model (CAT

Dynamic myosin activation promotes collective morphology and migration by locally balancing oppositional forces from surrounding tissue

Dynamic myosin activation promotes collective morphology and migration by locally balancing oppositional forces from surrounding tissue. Molecular Biology of the Cell, 27(12), 1898-1910. doi:10.1091/mbc.E15-10-0744Migrating cells need to overcome physical constraints from the local microenvironment to navigate their way through tissues. Cells that move collectively have the additional challenge of negotiating complex environments in vivo while maintaining cohesion of the group as a whole. The mechanisms by which collectives maintain a migratory morphology while resisting physical constraints from the surrounding tissue are poorly understood. Drosophila border cells represent a genetic model of collective migration within a cell-dense tissue. Border cells move as a cohesive group of 6-10 cells, traversing a network of large germ line-derived nurse cells within the ovary. Here we show that the border cell cluster is compact and round throughout their entire migration, a shape that is maintained despite the mechanical pressure imposed by the surrounding nurse cells. Nonmuscle myosin II (Myo-II) activity at the cluster periphery becomes elevated in response to increased constriction by nurse cells. Furthermore, the distinctive border cell collective morphology requires highly dynamic and localized enrichment of Myo-II. Thus, activated Myo-II promotes cortical tension at the outer edge of the migrating border cell cluster to resist compressive forces from nurse cells. We propose that dynamic actomyosin tension at the periphery of collectives facilitates their movement through restrictive tissues
