Abstract:
Abstract The paper presents technical application of TeX high-level, descriptive markup language for processing geological dataset from soil laboratory. Geotechnical measurements included equivalent soil cohesion, absolute and absolute deformation index, soil compressibility coefficient by time of immersion depth, exposure time to compressive strength to samples and physical and mechanical properties (humidity, density). Dataset was received from laboratory based experimental tests of the physical and mechanical properties of soils. Data were converted to csv table and processed by LaTeX. Methodology is based on LaTeX packages: {tikz}, {tikz-3dplot}, {tikzpicture}, {pgfplot}, {filecontetns}, {spy} for 3D plotting showing correlation in variables and descriptive statistical analysis based on the data array processing. Results demonstrated LaTeX scripts and graphics: 2D and 3D scatterplots, ternaries, bar charts, boxplots, zooming techniques detailing fragment of the plot, flowchart. Research novelty consists in technical approach of TeX language application for geo- logical data processing and graphical visualization. Engineering graphics by TeX was demonstrated with screenshots of the codes used for plotting.

Abstract:
We test the universal finite-size scaling of the cluster mass order parameter in two-dimensional (2D) isotropic and directed continuum percolation models below the percolation threshold by computer simulations. We found that the simulation data in the 2D continuum models obey the same scaling expression of mass M to sample size L as generally accepted for isotropic lattice problems, but with a positive sign of the slope in the ln–ln plot of M versus L. Another interesting aspect of the finite-size 2D models is also suggested by plotting the normalized mass in 2D continuum and lattice bond percolation models versus an effective percolation parameter, independent of the system structure (i.e., lattice or continuum) and of the possible directions allowed for percolation (i.e., isotropic or directed) in regions close to the percolation thresholds. Our study is the first attempt to map the scaling behavior of the mass for both lattice and continuum model systems into one curve.

Abstract:
The existing temple complex in Hampi, Karnataka, India was extensively studied, analyzed and documented. The complex was measured-drawn and digitized by plotting its edges and vertices using AutoCAD to generate 2d drawings. The graphic 2d elements developed were extended into 3 dimensional objects using Google sketch-up. The tool has been used to facilitate the visual re-construction to achieve the architecture of the temple in its original form. 3D virtual modelling / visual reconstruction helps us to visualize the structure in its original form giving a holistic picture of the Vijayanagara Empire in all its former glory. The project is interpreted graphically using Auto-CAD drawings, pictorially, digitally using Sketch-Up model and Kinect.

Abstract:
Based on the depth-sorting hidden-line removal algorithm, new methods of producing silhouette and raised level-curve diagrams with the hidden-lines removed of single-valued functions of two variables are presented. An algorithm of generating accurate truncated representations over the z-axis of the same types of functions is also described. These methods are particularly advantageous when plotting multimodal functions, noisy data or penalized objective functions encountered in optimization problems. Since all the graphic operations are performed entirely in the 2D image-space, the methods presented are suitable for implementation in low memory hardware like hand-held calculators and field instruments.

Abstract:
The d2Dplot computer program provides a set of tools for the visualization, processing and analysis of 2D X-ray diffraction (2DXRD) data. Among the operations available there are the sum/subtraction of 2DXRD images, conversion to 1D data (powder pattern), azimuthal plotting, calibration of instrumental parameters, background subtraction and a command-line mode to run operations inside data processing pipelines. The graphical user interface allows easy use of the program. It also includes two main features: (i) the possibility of creating a user compound database to help in the fast phase identification of similar samples, and (ii) a detailed peak analysis routine for the application of the through-the-substrate microdiffraction methodology.

Abstract:
ABSTRACT Expanding nebulae are produced by mass-loss from stars, especially during late stages of evolution. Multidimensional simulation of these nebulae requires high resolution near the star and permits resolution that decreases with distance from the star, ideally with adaptive time-steps. We report the implementation and testing of static mesh-refinement in the radiation-magnetohydrodynamics (R-MHD) code pion, and document its performance for 2D and 3D calculations. The bow shock produced by a hot, magnetized, slowly rotating star as it moves through the magnetized ISM is simulated in 3D, highlighting differences compared with 2D calculations. Latitude-dependent, time-varying magnetized winds are modelled and compared with simulations of ring nebulae around blue supergiants from the literature. A 3D simulation of the expansion of a fast wind from a Wolf–Rayet star into the slow wind from a previous red supergiant phase of evolution is presented, with results compared with results in the literature and analytic theory. Finally, the wind–wind collision from a binary star system is modelled with 3D MHD, and the results compared with previous 2D hydrodynamic calculations. A python library is provided for reading and plotting simulation snapshots, and the generation of synthetic infrared emission maps using torus is also demonstrated. It is shown that state-of-the-art 3D MHD simulations of wind-driven nebulae can be performed using pion with reasonable computational resources. The source code and user documentation is made available for the community under a BSD3 licence.

Abstract:
Predictive maintenance, which means detection of failure ahead of time, is one of the pillars of Industry 4.0. An effective method for this technique is to track early signs of degradation before failure occurs. This paper presents an innovative failure predictive scheme for machines. The proposed scheme combines the use of the full spectrum of vibration data from the machines and a data visualization technology. This scheme requires no training data and can be started quickly after installation. First, we proposed to use the full spectrum (as high-dimensional data vectors) with no cropping and no complex feature extraction and to visualize the data behavior by mapping the high-dimensional vectors into a two-dimensional (2D) map. This ensures simplicity of the process and less possibility of overlooking important information as well as provide a human-friendly and human-understandable output. Second, we developed a real-time data tracker that can predict failure at an appropriate time with sufficient allowance for maintenance by plotting real-time frequency spectrum data of the target machine on a 2D map created from normal data. Finally, we verified our proposal using vibration data of bearings from real-world test-to-failure measurements obtained from the IMS dataset.

Abstract:
The structural, mechanical, and thermodynamic properties of platinum group metals (Pt, Pd, and Ru) were systematically investigated by first-principles calculations based on density functional theory. Comparative studies show that Ru has the best comprehensive mechanical properties. Based on the Pugh’s rule and Poisson’s ratio, it is judged that Pt and Pd are ductility materials, and Ru exhibits obvious brittleness. Furthermore, the elastic anisotropy is also discussed by plotting both the 3D contours and the 2D planar projections of Young's modulus and shear modulus. The predicted elastic anisotropy factors indicate that the degree of elastic anisotropy of Pd is significant, while Ru has the smallest elastic anisotropy. By using the Clarke’s model, the minimum thermal conductivities of these metals have also been analyzed, and the results indicate that the low minimum thermal conductivity is proportional to the Debye temperature ΘD. The above results can provide a valuable reference for revealing the microscopic deformation mechanism and designing new materials.

Abstract:
OpenModelica is an open-source based development environment for Modelica, and an open source modelling and simulation platform. One of the main reasons for this thesis is the desire to change the existing plotting package into something more future safe due to performance issues of the existing plotting package in the OpenModelica framework. The package should be used in all OpenModelica tools, OMEdit, OMShell, and OMNotebook. The second part of the thesis includes implementing two additional shapes, a text shape and a bitmap shape to OpenModelicas graphical editor OMEdit. As a result of this work, a new plotting tool was developed and adopted as part of the OpenModelica platform; OMPlot.

With the rise of individualism, a small variety of customized merchandise has become a thend for consumers. In 2013 ,there is a magazine that called"Economist"even used "third industrial revolution" to define the influence that 3D printerwas brought. 3D print 3D printer not only rapid prototype manufacturing,but also help users do them by them-selves. Currently, there are many designs and source codes of 3D printing machine made users do them by themselves. However, there are few informations about academic and rigorous literature. For this reason, we want to do our best to construct a 3D print machines, faithfully rendered its manufacturing methods, and sorting out the problems that may occur .This thesis is divided into two main parts: the manufacturing process of the plotter 2D and 3D printer and some problems you may face. Due to the adoption of 3D printer used "Multilayer manufacturing" principles to print each layer is similar to 2D plotters. Therefore, we first use 2D drawing machine to present the production process and curve approximation algorithm. Above of algorithm can be extended to 3D print machines. The 3D Printing unique issues, such as temperature control, multi-scheduling, etc. We will also explore and and discuss all. I hope to achieve to contribute to a successor when the construction of 3D print machines, able some to avoid possible problems that mayface saving time to develop and to improve the manufacturing of engineering technology.

"when only limited sample sizes are available from the plant breeder. Some millers prefer batch-operated experimental mills such as the Allis-Chalmers or Ross Mill Stands because the milling procedure can be adjusted at each stage on the basis of a visual examination, the yields, and stock quality throughout the mill flow. When evaluating the results of experimental milling, two factors are usually considered: flour extraction (the percentage of the wheat recovered as flour) and flour ash. The lower the flour ash and the brighter the flour color, the more desirable the wheat for milling. The following two formulas are used to evaluate wheat milling quality from experimental milling data [40]: Milling rating = % extraction of straight grade flour — (ash x 100) FIGURE 5 The Brabender Quadrumat Junior laboratory mill. (Courtesy of C. W. Brabender Instruments Co., South Hacken-sack, NJ.) Milling value = % extraction of straight grade flour — Kent Jones flour color Higher milling ratings and milling values are preferred. The milling quality of different wheats can also be judged by comparing their cumulative ash curves [28]. Cumula-tive ash curves are constructed by arranging mill streams in ascending order of ash on a constant moisture basis and by plotting cumulative ash against cumulative extraction for each successive blend of millstreams. Wheats that ex-hibit the lowest initial flour ash and the slowest rate of ash increase with increasing flour extraction are preferred. The results of this comparison can be expressed in terms of a single numerical score, the curve index. A line is drawn from the 30% extraction point on the cumulative curve to the 70% extraction point (Fig. 6). The distance on the 50% extraction level from the curve to the drawn line, when measured at right angle to the line, is called depth, D. It is used in the calculation of the curve index: FIGURE 4 The Brabender Quadrumat Senior laboratory mill. (Courtesy of C. W.

Abstract:
Abstract In the industry of manufacturing photo mask of Liquid Crystal Display (LCD) or Vacuum Florescent Display (VFD), there have been strong needs for a CAD system of fabricating a pattern mask directly from the CAD data of 2D mask design. This paper presents brief introductions to several algorithms and implementations used in the development of a CAD system for LCD/VFD mask fabrication. For the laser writer, it is simply required to provide the loop information of the pattern shapes. The ray casting algorithm is applied to derive this loop information from the CAD data composed of random vector list. For the photo plotter, the selection of the proper apertures and their plotting paths are derived to expose exact pattern shapes in the shortest time. The idea of Voronoi diagram is used to efficiently obtain an exact aperture path in this study. This paper also features some ideas for automatically detecting and fixing errors of designer’s drawing.

Abstract:
Abstract The aim of the present paper is to improve the physical understanding of flow irregularities in the blade passing signal of turbomachinery rotors, since the novel stall warning method presented in part I is based upon those irregularities. For this purpose, a complementary instrumentation was used in a single stage axial compressor. A set of pressure transducers evenly distributed along the circumference surface mounted in the casing near the rotor tip leading edges is measuring the time-resolved wall pressures simultaneously to an array of transducers recording the chord-wise static pressures. The latter allows for plotting quasi-instantaneous 2D-pressure contours. Any occurring flow disturbances causing the before mentioned irregularity can later be classified using validated frequency analysis methods being applied to the data from the circumferential sensors. While leaving the flow coefficient constant, a continuously changing number of prestall flow disturbances appears to be causing the very spectral signature which is known from investigations on Rotating Instability. Any arising number of disturbances is matching a specific mode order to be found within the spectral signature. While the flow coefficient is reduced the propagation speed of prestall disturbances increases linearly as the speed seems to be independent from the clearance size. Data taken beyond the stalling limit demonstrate a complex superposition of stall cells and flow disturbances which the title “prestall disturbance” therefore doesn’t fit to precisely any more. Different convection speeds allow the phenomena to be clearly distinguished from each other.

Abstract:
A Rieke diagram [1] is a magnetron characteristic that visualizes the dependence of the generated frequency fg and the net delivered power PL on the load reflection coefficient GR. GR is defined in a specific magnetron-to-waveguide coupling structure called the standard or reference launcher (Fig. 1). The diagram is plotted as a family of isolines of constant fg and of constant PL in the polar diagram of GR. Rieke diagrams are essential in the design of applications without isolators, such as domestic or professional microwave ovens. Constructing Rieke diagrams is tedious, time-consuming and equipment-demanding [2], [3], preventing systematic studies of their dependence on operating conditions, such as anode voltage and its ripple, filament current, mounting repeatability, etc. We have devised a procedure, centering around a high-power automatic impedance matching device (autotuner), which enables fully automatic measurement and plotting of the stated dependences. A block diagram of the setup is shown in Fig. 1. The autotuner, when terminated in a match (waterload), can accomplish a task inverse to impedance matching: realizing any desired reflection coefficient GR. The measurement consists of stepping through a grid of n suitably chosen reflection coefficients GR = xR + jyR, covering a desired area of the polar diagram. Each GR is measured accurately by the autotuner, along with the corresponding fg and PL. Thus, raw data for constructing a Rieke diagram are obtained, the data consisting of a collection of n points {GR, fg, PL}i, i = 1…n, with GR, in general, irregularly scattered in the complex plane. A dedicated MATLAB routine then reads the data, sorts them out to create tabulated functions fg = f(xR, yR), PL = f(xR, yR), approximates these by a 2D spline, and uses the splines to plot smoothed isocontours for chosen constant values of fg and PL, completing thus the desired Rieke diagram construction. We will present details of this procedure as well as real-life examples. Fig. 1. Rieke diagram measurement setup. References Meredith, R.

Abstract:
The paper presents a novel post-processing platform, AERO-POST, for two-dimensional steady and unsteady flow fields around turbomachinery blade rows. AERO-POST is a data manipulation facility, with a number of associated translators to read CFD results from a library of codes and experimental/numerical databases, and with a collection of conventions and associated automatic convertions so that numerical and experimental data can be rapidly compared in a consistent way. A number of specialized and well validated post-processing and visualization tools for unsteady flows around vibrating blade rows and relatively moving blade rows (aerodynamic damping and other unsteady aerodynamic coefficients, influence coefficients, stability parameter, stability maps,…) are also implemented to scrutinize unsteady CFD results. AERO-POST currently supports a library of ten CFD codes and three experimental/numerical databases, and three graphics libraries/packages. The program internal data structure and architecture is designed to support the storage of multi-dimensional variables with data attributes grouped into multiple data sets, and an extensive range of CFD reading routines, data manipulation tools and graphics libraries. Collectively, these features provide a set of powerful and original post-processing options allowing users to compare and investigate their CFD results more efficiently than with classical plotting softwares. These original post-processing and plotting options are illustrated on a series of applications.
