1 Introduction 1 Introduction About SigmaPlot SigmaPlot 10.0 makes it easier for you to present your findings accurately using precise, publication-quality graphs, data analysis and presentation tools. SigmaPlot 10.0 offers numerous scientific options such as automatic error bars, regression lines, confidence intervals, axis breaks, technical axis scales, non-linear curve fitting and a data worksheet for powerful data handling. SigmaPlot is a state-of-the-art technical graphing program designed for the Windows platform. It is certified for Windows NT, Windows 2000, Microsoft Office 98, 2000, and Windows XP. SigmaPlot is specifically designed to aid in documenting and publishing research, specializing in the graphical presentation of results. Creating and editing graphs is easy. Just click a Graph toolbar button, pick your data with the Graph Wizard, and you can create a graph in seconds. You can also use templates to apply favorite graphs again and again. SigmaPlot 10.0 also includes a powerful nonlinear curve fitter, a huge scientific data worksheet that accommodates large data sets, summary statistics, a mathematical transform language and much more. OLE2 technology is fully supported. You can annotate graphs with the Microsoft Word Equation Editor, edit your graphs directly inside Word or PowerPoint, or plot your data with an Excel spreadsheet right inside SigmaPlot 10.0. Graph Types and Styles SigmaPlot10.0’s selectable Graph Type determines the structure of your graph. SigmaPlot 10.0 provides many different types of two- and three-dimensional Cartesian (XY and XYZ) graphs, as well as pie charts and polar plots. Graph Style determines how data is plotted on a graph. Available styles depend on the selected Graph Type. SigmaPlot 10.0’s Graph Wizard conveniently displays all available graph styles associated with each graph type. 2 Chapter 1 The Graph Style Gallery and Templates Use the SigmaPlot Graph Style Gallery create and store true graph templates using any existing graph style as the model. For more information, see “Using the Graph Style Gallery” in Chapter 4. Every graph that you add to the Graph Style Gallery is saved as a bitmap image. You can later apply this as a template for future graphs, saving you time and effort. For more information, see “Using the Graph Style Gallery” on page 157. Figure 1-1 The Graph Style Gallery Templates. The SigmaPlot 10.0 template notebook contains a variety of page layouts. Apply these predetermined template attributes to previously saved pages and graphs, or create a user-defined template. Store your templates in a SigmaPlot Notebook Template file (.JNT). You may want to create your own template notebook. For more information, see “Using Graph Pages as Templates” on page 237. 3 Introduction Graph Defaults Preset graph attribute default settings, such as size and position, font, and symbol, line and bar settings. Axis Scales Create multiple axes for 2D graphs. SigmaPlot 10.0 , by default, automatically calculates axis ranges and enables each plot to contain separate X and Y axes. Tick Marks. Use both major and minor axis tick marks and grid lines. Tick intervals, length, direction, thickness, and color are all adjustable; grid line types are also adjustable. Tick labels can be numeric, time series, or customized, using labels in a worksheet column. Axis Breaks. You can specify an axis break with a different post-break tick interval. Automatic Legends Generate legends automatically, or ungroup legends and individually customize text labels. Smooth Data Smooth sharp variations in dependent values within 2D and 3D data sets using SigmaPlot 10.0 smoothing algorithms. SigmaPlot 10.0 Worksheet The SigmaPlot 10.0 worksheet is capable of containing data up to 32,000,000 rows by 32,000 columns. Enter data in columns or rows, and perform calculations either row- wise or column-wise. Worksheet cells within columns are adjustable, and capable of holding up to 14 significant digits. Place labels, customized fill colors and patterns, and error bar direction codes into these cells in order to specify changes to graphs. 4 Chapter 1 Microsoft Excel SigmaPlot 10.0 uses automation communication standards to create and open Excel workbooks within SigmaPlot 10.0. This functionality enables you to run transforms, perform statistical tests, and graph data stored in Excel worksheets. Statistics Descriptive statistics are available for all your worksheet columns.

SigmaPlot now offers seven new line types for line plots and line scatter plots, free-form lines, boxes and ellipses. There are also new line types available in the Graph Properties dialog box and the Page toolbar. Use these line types in 2D and 3D graphs. More patterns. Twenty-five new fill patterns for bar charts, box plots, pie charts, area plots and free-form boxes and ellipses. New fill patterns have been implemented in the Graph Properties dialog box and the Page toolbar. Use the new fill patterns in 2D and 3D graphs. Dynamic Curve Fitting. Compliments the Regression Wizard by providing hundreds of initial parameter estimates to minimize the squared residual errors, produce individual curve fits for each, and chose the best in a matter of seconds. Greatly increase the likelihood that the answer you get is the correct answer for your data. Achieves the best fit by automatically choosing and trying numerous initial parameter estimates to find the global minimum, even if you supply a complicated model with problematic data. Solve harder problems that normally don't converge. Added New Weighting Options to Curve Fitter. Allows the choice between using reduced chi-squared weighting or not in nonlinear regression. Now you can use whichever weighting method preferred by your field. Many packages use reduced chi-square weighting but certain fields believe that this is not the correct way. New 3D Mesh Plots with Contour Projection. Allows you to put contour plots into 3D graphs to reflect the Z values of the plotted data. Select Positive Direction for Polar Plots. Now you can select a positive direction for polar plots. Automatically create both clockwise and counterclockwise polar graphs.

    Limits of Pgl(3)-Translates of Plane Curves, I

    LIMITS OF PGL(3)-TRANSLATES OF PLANE CURVES, I PAOLO ALUFFI, CAREL FABER Abstract. We classify all possible limits of families of translates of a fixed, arbitrary complex plane curve. We do this by giving a set-theoretic description of the projective normal cone (PNC) of the base scheme of a natural rational map, determined by the curve, 8 N from the P of 3 × 3 matrices to the P of plane curves of degree d. In a sequel to this paper we determine the multiplicities of the components of the PNC. The knowledge of the PNC as a cycle is essential in our computation of the degree of the PGL(3)-orbit closure of an arbitrary plane curve, performed in [5]. 1. Introduction In this paper we determine the possible limits of a fixed, arbitrary complex plane curve C , obtained by applying to it a family of translations α(t) centered at a singular transformation of the plane. In other words, we describe the curves in the boundary of the PGL(3)-orbit closure of a given curve C . Our main motivation for this work comes from enumerative geometry. In [5] we have determined the degree of the PGL(3)-orbit closure of an arbitrary (possibly singular, re- ducible, non-reduced) plane curve; this includes as special cases the determination of several characteristic numbers of families of plane curves, the degrees of certain maps to moduli spaces of plane curves, and isotrivial versions of the Gromov-Witten invariants of the plane. A description of the limits of a curve, and in fact a more refined type of information is an essential ingredient of our approach.

    Unsupervised Smooth Contour Detection

    Published in Image Processing On Line on 2016–11–18. Submitted on 2016–04–21, accepted on 2016–10–03. ISSN 2105–1232 c 2016 IPOL & the authors CC–BY–NC–SA This article is available online with supplementary materials, software, datasets and online demo at https://doi.org/10.5201/ipol.2016.175 2015/06/16 v0.5.1 IPOL article class Unsupervised Smooth Contour Detection Rafael Grompone von Gioi1, Gregory Randall2 1 CMLA, ENS Cachan, France ([email protected]) 2 IIE, Universidad de la Rep´ublica, Uruguay ([email protected]) Abstract An unsupervised method for detecting smooth contours in digital images is proposed. Following the a contrario approach, the starting point is defining the conditions where contours should not be detected: soft gradient regions contaminated by noise. To achieve this, low frequencies are removed from the input image. Then, contours are validated as the frontiers separating two adjacent regions, one with significantly larger values than the other. Significance is evalu- ated using the Mann-Whitney U test to determine whether the samples were drawn from the same distribution or not. This test makes no assumption on the distributions. The resulting algorithm is similar to the classic Marr-Hildreth edge detector, with the addition of the statis- tical validation step. Combined with heuristics based on the Canny and Devernay methods, an efficient algorithm is derived producing sub-pixel contours. Source Code The ANSI C source code for this algorithm, which is part of this publication, and an online demo are available from the web page of this article1.

  • Calculus-Free Derivatives of Sine and Cosine

    Calculus-Free Derivatives of Sine and Cosine

    Calculus-free Derivatives of Sine and Cosine B.D.S. McConnell [email protected] Wrap a square smoothly around a cylinder, and the curved images of the square’s diagonals will trace out helices, with the (original, uncurved) diag- onals tangent to those curves. Projecting these elements into appropriate planes reveals an intuitive, geometric development of the formulas for the derivatives of sine and cosine, with no quotient of vanishing differences re- quired. Indeed, a single —almost-“Behold!”-worthy— diagram and a short notational summary (see the last page of this note) give everything away. The setup. Consider a cylinder (“C”) of radius 1 and a unit square (“S”), with a pair of S’s edges parallel to C’s axis, and with S’s center (“P ”) a point of tangency with C’s surface. We may assume that the cylinder’s axis coincides with the z axis; we may also assume that, measuring along the surface of the cylinder, the (straight-line) distance from P to the xy-plane is equal to the (arc-of-circle) distance from P to the zx-plane. That is, we take P to have coordinates (cos θ0, sin θ0, θ0) for some θ0, where cos() and sin() take radian arguments. Wrapping S around C causes the image of an extended diagonal of S to trace out the helix (“H”) containing all (and only) points of the form (cos θ, sin θ, θ). Moreover, the original, uncurved diagonal segment of S de- termines a vector, v :=< vx, vy, vz >, tangent to H at P ; taking vz = 1, we assure that the vector conveniently points “forward” (that is, in the direction of increasing θ) along the helix.

    Perylene Diimide: A Versatile Building Block for Complex Molecular Architectures and a Stable Charge Storage Material Margarita Milton Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2018 © 2018 Margarita Milton All rights reserved ABSTRACT Perylene Diimide: A Versatile Building Block for Complex Molecular Architectures and a Stable Charge Storage Material Margarita Milton Properties such as chemical robustness, potential for synthetic tunability, and superior electron-accepting character describe the chromophore perylene-3,4,9,10-tetracarboxylic diimide (PDI) and have enabled its penetration into organic photovoltaics. The ability to extend what is already a large aromatic core allows for synthesis of graphene ribbon PDI oligomers. Functionalization with polar and ionic groups leads to liquid crystalline phases or immense supramolecular architectures. Significantly, PDI dianions can survive in water for two months with no decomposition, an important property for charge storage materials. We realized the potential of PDI as an efficient negative-side material for Redox Flow Batteries (RFBs). The synthetic tunability of PDI allowed for screening of several derivatives with side chains that enhanced solubility in polar solvents. The optimized molecule, PDI[TFSI]2, dissolved in acetonitrile up to 0.5 M. For the positive-side, we synthesized the ferrocene oil [Fc4] in high yield. The large hydrodynamic radii of PDI[TFSI]2 and [Fc4] preclude their ability to cross a size exclusion membrane, which is a cheap alternative to the typical RFB membranes. We show that this cellulose-based membrane can support high voltages in excess of 3 V and extreme temperatures (−20 to 110 °C).
