a matlab based graphical user interface program for computing functionals of the geopotential up to ultra high degrees and orders
Computers & Geosciences, 2013Co-Authors: Blažej Bucha, Juraj JanakAbstract:Fast spherical harmonic synthesis (SHS) at multiple points based on the lumped coefficients approach is a very well-established technique. However, this method cannot be applied to SHS at irregular surfaces, as the points must be regularly spaced and refer to a regular surface such as the sphere or the ellipsoid of revolution. In this paper we present a MATLAB ? -based graphical user interface software for ultra-high degree (e.g. tens of thousands or even higher) SHS on grids at irregular surfaces, like the Earth surface. This software employs the highly efficient lumped coefficient approach for SHS at regular surfaces and the Taylor series expansions to continue the functionals to the irregular surfaces, e.g. the Earth surface. The generalized idea of continuing functionals using the Taylor series was presented by Hirt (2012) (J. Geod. 86, 729-744). We took advantage of the software GrafLab (Bucha and Janak, 2013. Comput. Geosci. 56, 186-196), which employs the lumped coefficients approach, and developed a new software isGrafLab (Irregular Surface GRAvity Field LABoratory). Compared to the commonly used "two loops" approach, the factor of increased computational speed can reach a value of several hundreds. isGrafLab allows accurate evaluation of 38 functionals of the geopotential on grids at irregular surfaces. High orders of the Taylor series can be used for the continuation. The new software offers all the other options available in GrafLab, such as the employment of three different approaches to compute the fully normalized associated Legendre functions, the graphical user interface or the possibility to depict data on a map. HighlightsA new MATLAB-based software for spherical harmonic synthesis is presented.Spherical harmonic synthesis is efficiently performed on grids at irregular surfaces.The program employs the lumped coefficients approach and Taylor series expansions.The program has been developed with a graphical user interface.

Session 2220 Development of a Matlab-Based graphical user interface Environment for PIC Microcontroller Projects
2014Co-Authors: Sang-hoon Lee, Vikram KapilaAbstract:Peripheral interface Controllers (PICs) are inexpensive microcontroller units with built-in serial communication functionality. Similarly, Matlab, a widely used technical computing software, allows serial communication with external devices. In addition, Matlab provides graphical design tools such as Simulink and Dials and Gauges Blockset. This paper exploits the serial communication capability of PIC microcontrollers and the Matlab software along with graphical design tools of Matlab to create a Matlab-based graphical user interface (GUI) environment for PIC microcontroller projects. Three examples are included to illustrate that the integration of low-cost PIC microcontrollers with the Matlab-based GUI environment allows data acquisition, data processing, data visualization, and control

matlab based graphical user interface development for basic stamp 2 microcontroller projects
American Control Conference, 2004Co-Authors: Yanfang Li, Sami Harari, Hong Wong, Vikram KapilaAbstract:Basic Stamp 2 (BS2) is a popular microcontroller used both in hobby and industrial projects. Similar to other microcontrollers, the BS2 programming environment lacks graphical user interface (GUI) capability. In this paper, we present an approach to endow the BS2 microcontroller with GUI capabilities by interfacing it with Matlab and by exploiting Matlab's abundant GUI tools. The proposed Matlab-based GUI environment for BS2 relies on the use of serial communication between the BS2 and a personal computer. We present three examples to demonstrate the efficacy of our approach.

jaxodraw a graphical user interface for drawing feynman diagrams
Computer Physics Communications, 2004Co-Authors: Daniele Binosi, L TheuslAbstract:JaxoDraw is a Feynman graph plotting tool written in Java. It has a complete graphical user interface that allows all actions to be carried out via mouse click-and-drag operations in a WYSIWYG fashion. Graphs may be exported to postscript/EPS format and can be saved in XML files to be used in later sessions. One of the main features of JaxoDraw is the possibility to produce L ATEX code that may be used to generate graphics output, thus combining the powers of TEX/L ATEX with those of a modern day drawing program. With JaxoDraw it becomes possible to draw even complicated Feynman diagrams with just a few mouse clicks, without the knowledge of any programming language.

Program summary Title of program: JaxoDraw Catalogue identifier: ADUA Program summary URL: http://cpc.cs.qub.ac.uk/summaries/ADUA Program obtainable from: CPC Program Library, Queen's University of Belfast, N. Ireland Distribution format: tar gzip file Operating system: Any Java-enabled platform, tested on Linux, Windows ME, XP, Mac OS X Programming language used: Java License: GPL Nature of problem: Existing methods for drawing Feynman diagrams usually require some ‘hard-coding’ in one or the other programming or scripting language. It is not very convenient and often time consuming, to generate relatively simple diagrams. Method of solution: A program is provided that allows for the interactive drawing of Feynman diagrams with a graphical user interface. The program is easy to learn and use, produces high quality output in several formats and runs on any operating system where a Java Runtime Environment is available. Number of bytes in distributed program, including test data: 2 117 863 Number of lines in distributed program, including test data: 60 000 Restrictions: Certain operations (like internal latex compilation, Postscript preview) require the execution of external commands that might not work on untested operating systems. Typical running time: As an interactive program, the running time depends on the complexity of the diagram to be drawn.

charmm gui a web based graphical user interface for charmm
Journal of Computational Chemistry, 2008Co-Authors: Taehoon Kim, Vidyashankara IyerAbstract:CHARMM is an academic research program used widely for macromolecular mechanics and dynamics with versatile analysis and manipulation tools of atomic coordinates and dynamics trajectories. CHARMM-GUI, http://www.charmm-gui.org, has been developed to provide a web-based graphical user interface to generate various input files and molecular systems to facilitate and standardize the usage of common and advanced simulation techniques in CHARMM. The web environment provides an ideal platform to build and validate a molecular model system in an interactive fashion such that, if a problem is found through visual inspection, one can go back to the previous setup and regenerate the whole system again. In this article, we describe the currently available functional modules of CHARMM-GUI Input Generator that form a basis for the advanced simulation techniques. Future directions of the CHARMM-GUI development project are also discussed briefly together with other features in the CHARMM-GUI website, such as Archive and Movie Gallery.
