Designing a database is a complex task and the normalization theory is a useful aid in the design process. In this paper, a tool is presented which aims to handle the normalization process up to third normal form(3NF) and even imparts the normalized relations to its users in different formats. The objective of the system is to provide an effective and efficient e-Learning system to individuals to learn normalization in an easy and quick manner and an impeccable solution for organizations dealing with excessive data.

Despite this, analysis of debris at all length-scales has not yet been performed, and therefore the nature of debris produced by electrical discharge processes is not fully understood. In this study debris created by the machining of two electrode materials set as negative polarity, silicon and titanium carbide, was centrifuged and imaged using SEM and TEM. From this analysis it was shown that electrode debris is 1 nm or lower and up to 10 m in size. Population analysis of the particle size distribution was used to

VLC is a technique used for data transmission at very high speeds through light, which transfers data by varying its intensity at unperceivable rates. The proposed solution also establishes a closed loop with an overhead camera which mocks like a GPS in the swarm environment. Positional information of the robots is given by augmented reality tags and this data is fed-back to the robots via VLC. The paper elaborately describes the approach used to exploit off-the-shelf components for facilitating VLC. Overhead localization and the closed loop made here control each swarm robot with simplex communication. Problems faced while prototyping and overcoming them in revisions have been also described.

At this same time the present statistics about the average water table in the country indicates a rapid fall in the level. There is an immense need to make a proper utilization of water and increase in ground water level by means of rain water harvesting techniques. This paper presents an approach for determining the water runoff from a particular built-up area based on the satellite image of that area. The process involves segmentation and classification of satellite images. The classification is mainly done using texture analysis techniques. The satellite image is classified into various classes like built up region, soil region, grass region and water region. The area under built up region is computed, then based on the relationships between the surface type and the rainfall, the water runoff is computed; which in turn is used ...

This virus i s naturally resistant to various antibiotics, and tis no proper treatment for infection caused by this patho gen. And hence there is a need for new drugs and ap proaches to combat the life threatening infection caused by Ebo la virus. Computer aided drug design is one of the powerful tools for discovering new drug leads against important ta rgets. The various proteins that are essential for pathogenesis of organism are selected as targets. The viral protein s vp35 and vp40 are capable of eliciting protective immune responses to EBOV. The various functions of these p roteins in pathogenesis suggested them as potential drug targets to control EBOV infections. After the prote ins were selected as target, new leads were chosen from a subset of small molecules that scored well when docked in silico against targets. The drug ...

In this work, we study such suspensions using the discrete element method (DEM) coupled with a kinetic theory based lattice Boltzmann method (LBM) [4] to resolve particle dynamics and multiple fields, e.g., fluid or electric-field, respectively. Position updates of each particle computed in DEM at a given time are communicated to the LBM algorithm through a DEM-LBM interface. Here, we use sophisticated extrapolation methods to transfer the particle-centric information of DEM to the computational grid-level information for the LBM and vice versa. Coupling of DEM and LBM has only very recently been examined [5,6]. The design of this interface is important to obtain time accurate results. The present work details on the analysis of particle suspension in viscous fluid (such as dielectric f...

Studies have shown that the vast majority of the content in the WWW resides in the deep web sources which store their content in backend databases which have been growing by leaps and bounds. Due to its great importance for database applications database schema design has attracted substantial research. Database normalization is a theoretical approach for structuring a database schema and it is very well developed but unfortunately, the theory is not yet understood well by practitioners. It has been difficult to motivate students to learn database normalization because students think the subject to be dry and purely theoretical. In this paper, a tool called Web Based Relational Database Design and Normalization Tool is proposed, which handles normalization for Relational Databases. The tool is suitable for relational data modeling in systems analysis and design and data management pr...

However, they remain prone to dendrite formation on charging, limiting battery cycling. Dendritic zinc deposition occurs under a mass-transfer limitation and convection improves cycle life but the phenomenon is not well understood. Naybour [2] qualitatively studied the effect of convection on dendritic growth of zinc. However, the flow modeled was not laminar and significantly higher than required for feasible operation of a flow-assisted battery. Gallaway et al [3] reported a strong dependence of zinc deposition on electrolyte flow and current density, which highlights the need for theoretical model to predict the growth and form of zinc dendrites.

Despite this, analysis of debris at all length-scales has not yet been performed, and therefore the nature of debris produced by electrical discharge processes is not fully understood. In this study debris created by the machining of two electrode materials set as negative polarity, silicon and titanium carbide, was centrifuged and imaged using SEM and TEM. From this analysis it was shown that electrode debris is 1 nm or lower and up to 10 m in size. Population analysis of the particle size distribution was used to inform an electric field model based on a lattice Boltzmann method framework, simulating the effect of the presence of such debris on the electric field strength. This method is shown to be able to capture the local variation of the electric field and predict qualitatively the correct trend of the electric field strength increasing against the debris concentration. Such data is important for prediction and control of discharge gap size, as well as understanding the impact of a build-up of debris on uncontrolled sparking.

With SRI practices, grain yield was increased by 48% in these trials at the same time, there was an average water saving of 22% compared with inundated SMP rice. Water productivity with AWD-SRI management practices was almost doubled (0.68 g l-1) compared to CF-SMP (0.36 g l-1). Significant improvements were observed in the morphology of SRI plants in terms of root growth, plant/culm height, tiller number per hill, tiller perimeter, leaf size and number, leaf area index (LAI), specific leaf weight (SLW), and open canopy structure. These phenotypic improvements of the AWD-SRI crop were accompanied by physiological changes: greater xylem exudation rate, crop growth rate, mean leaf elongation rate (LER), and higher light interception by the canopy compared to rice plants grown under CF-SMP. SRI plants showed delayed leaf senescence and greater light utilization, and they maintained higher photosynthetic rates during reproductive and grain-filling stages. This was responsible for improvement in yieldcontributing characteristics and higher grain yield than from flooded rice with SMP. We conclude that SRI practices with AWD improve rice plants' morphology, and this benefits physiological processes that result in higher grain yield and water productivity.

We show that an off-lattice D3Q27 model exists with correct equilibrium to recover Galilean-invariant form of Navier-Stokes equation Í‘without any cubic errorÍ’. In the first part of this work, we show that the present model can capture two important features of the microflow in a single component gas: Knudsen boundary layer and Knudsen Paradox. Finally, we present numerical results corresponding to Couette flow for two representative Knudsen numbers. We show that the off-lattice D3Q27 model exhibits better accuracy as compared to more widely used on-lattice D3Q19 or D3Q27 model. Finally, our construction of discrete velocity model shows that there is no contradiction between entropic construction and quadrature-based procedure for the construction of the lattice Boltzmann model.

The quadratic least squares procedure is used for the estimation of first-order and second-order spatial gradients of the particle distribution functions. The distribution functions were extrapolated quadratically to the virtual upwind node. The time integration was performed using the fourth-order Runge-Kutta procedure. A grid convergence study was performed in order to demonstrate the order of accuracy of the present scheme. The formulation was validated for the benchmark two-dimensional, laminar, and unsteady flow past a single circular cylinder. These computations were then investigated for the low Mach number simulations. Further validation was performed for flow past two circular cylinders arranged in tandem and side-by-side. Results of these simulations were extensively compared with the previous numerical data.

Due to the complex boundary of the trapezoidal cavity, here the extrapolation scheme proposed by Guo et al. is used to treat curved boundary. In our numerical simulations, the effects of the Reynolds number (Re) and the top angle h on the strength, center position and number of vortices in the isosceles trapezoidal cavities are studied. Re is varied from 100 to 15,000, and the top angle h ranges from 50 to 90. Numerical results show that, as Re increases, the phenomena in the cavity become more and more complex, and the number of the vortexes increases. We also found that the vortex near the bottom wall breaks up into two smaller vortices as h increases up to a critical value. Furthermore, as Re is increased, the flow in the cavity undergoes a complex transition (from steady to the periodic flow, and finally to the chaotic flow). At last, the scope of critical Re for flow transition from steady to periodic state, and from periodic to chaotic state is presented for different top angles h.
