  • Importance Of Grain Size Analysis

    Particle size distribution Introduction The purpose of this lab was to determine the particle size distribution of a particular soil sample by carrying out sieve analysis and hydrometer analysis tests. For the sieve analysis test, a graph for percent finer versus the grain size was plotted from the data collected. The graph was used to determine whether the soil sample was fine-grained or course-grained. Calculations for uniformity and gradation were then done to determine whether the soil was well graded, poorly graded or gap graded. For the hydrometer analysis test, the soil sample was dispersed in water so that the particles settled at different velocities with time. The percentage of soil suspended at specific time intervals were measured…

    milling. Each step is known as a unit operation and will be outlined below. The ingredients to make a pharmaceutical tablet will include the active pharmaceutical ingredients [API], and may require a bulking or binding agent which allows the tablet to be sufficiently large for consumption and provides sufficient surface properties of the particles within the mixture to facilitate suitable agglomeration for proper mixing and tableting, these ingredients are known as excipients. Tablets used…

  • Unified Soil Classification System

    I.a. Background Information The data in this report were based on the practicals in the laboratory. The data were used to identify and classify soils for engineering applications. The data were tabulated using Unified Soil Classification System (USCS) method, which is non-laboratory test and 2 classification of soils based on laboratory test. The two laboratory test classify soil methods are Classification of soil based on particular size distribution and Classify soil based on Atterberg…

  • Discrete Element Methods

    using particle-particle friction, particle-geometry friction and the particle density to simulate material behavior (Asaf et al., 2007). The particle size and shape distribution are also considered to be input DEM parameters. In DEM, spherical particles are usually preferred because of the efficiency of contact detection. However, when using this type of particles, the bulk friction of the assembly is usually too low compare to real material. There are two methods to increase the bulk friction…

  • Enkb Analysis

    modified to include Monte Carlo estimation of the constant coefficients. We recall that the standard particle filtering method suffers from weight degeneracy especially when the estimation includes static parameters. EnKF, however, does not suffer from degeneracy and provides a good estimate of the coefficients by integrating a sample minimum mean square estimate (MMSE) of the coefficients within the EnKF algorithm. Without loss of generality, let us consider a first-order wide-sense stationary…

  • Quasiclassical Elienberger Equations

    Quasiclassical Elienberger equations [129] for the green functions g(k , r, and order parameter , is a powerful tool to deal with inhomogeneous superconductors [130]. These functions depend on the so called, ‘Matsubara frequency’, , coordinate r, and wave vector k on the fermi surface. The dependence of green functions and order parameters on the wave vector k, makes them sensitive to the shape of fermi surface. This makes solution of Elienberger equations complicated in the system of complex…
