    The pack­age pro­vides sev­eral macros to ad­just boxed con­tent. One pur­pose is to sup­ple­ment the stan­dard graph­ics pack­age, which de­fines the macros \re­size­box, \scale­box and \ro­tate­box , with the macros\trim­box and \clip­box. The main fea­ture is the gen­eral \ad­just­box macro which ex­tends the “key=value” in­ter­face of \in­clude­graph­ics from the graph­ics pack­age and ap­plies it to gen­eral text con­tent. Ad­di­tional pro­vided box macros are \lap­box, \margin­box, \min­size­box, \max­size­box and \phan­tombox. All macros use the col­lect­box pack­age to read the con­tent as a box and not as a macro ar­gu­ment. This al­lows for all forms of con­tent in­clud­ing spe­cial ma­te­rial like ver­ba­tim con­tent. A spe­cial fea­ture of col­lect­box is used to pro­vide match­ing en­vi­ron­ments with the iden­ti­cal names as the macros.

    Welcome to Learn You a Haskell for Great Good! If you're reading this, chances are you want to learn Haskell. Well, you've come to the right place, but let's talk about this tutorial a bit first. I decided to write this because I wanted to solidify my own knowledge of Haskell and because I thought I could help people new to Haskell learn it from my perspective. There are quite a few tutorials on Haskell floating around on the internet. When I was starting out in Haskell, I didn't learn from just one resource. The way I learned it was by reading several different tutorials and articles because each explained something in a different way than the other did. By going through several resources, I was able put together the pieces and it all just came falling into place. So this is an attempt at adding another useful resource for learning Haskell so you have a bigger chance of finding one you like. This tutorial is aimed at people who have experience in imperative programming languages (C, C++, Java, Python …) but haven't programmed in a functional language before (Haskell, ML, OCaml …). Although I bet that even if you don't have any significant programming experience, a smart person such as yourself will be able to follow along and learn Haskell. The channel #haskell on the freenode network is a great place to ask questions if you're feeling stuck. People there are extremely nice, patient and understanding to newbies. I failed to learn Haskell approximately 2 times before finally grasping it because it all just seemed too weird to me and I didn't get it. But then once it just "clicked" and after getting over that initial hurdle, it was pretty much smooth sailing. I guess what I'm trying to say is: Haskell is great and if you're interested in programming you should really learn it even if it seems weird at first. Learning Haskell is much like learning to program for the first time — it's fun! It forces you to think differently, which brings us to the next section …

    The package enables the user to use beamer style operations on a canvas of the sizes provided by a0poster; font scaling is available (using packages such as type1cm if necessary). In addition, the package allows the user to benefit from the nice colour box handling and alignment provided by the beamer class (for example, with rounded corners and shadows). Good looking posters may be created very rapidly. Features include: scalable fonts using the fp and type1cm packages; posters in A-series sizes, and custom sizes like double A0 are possible; still applicable to custom beamer slides, e.g. 16:9 slides for a wide-screen (i.e. 1.78 aspect ratio); orientation may be portrait or landscape; a ‘debug mode’ is provided.

    Digitizing software for converting graphs and maps into numbers. Image files from scanners, digital cameras and screenshots are easily converted, and exported into spreadsheets. Introduction This open source, digitizing software converts an image file showing a graph or map, into numbers. The image file can come from a scanner, digital camera or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. The process starts with an image file containing a graph or map. The final result is digitized data that can be used by other tools such as Microsoft Excel and Gnumeric. Engauge (from en "make" and gauge "to measure") verb meaning to convert an image file containing a graph or map, into numbers. The term "Engauge" in Engauge Digitizer was invented for this project, since there seems to be no similar term in common use. Why Would You Need This Tool? Here are some real-life examples: You are an engineer with some graphs in decades-old documents, but you really need the numbers represented in those graphs so you can do analyses that will determine if a space vehicle is safe to fly. You are a graduate student gathering historical data from charts for your thesis. You are a webmaster with visitor statistics charts and you want to do statistical analyses. You ride a bike or boat and want to know how much distance you covered in your last trip, but you do not have an odometer or GPS unit. However, you do have a map. Nice Features Automatic curve tracing of line plots Automatic point matching of point plots Automatic axes matching Automatic grid line removal for improved curve tracing Handles cartesian, polar, linear and logarithmic graphs Support for drag-and-drop and copy-and-paste makes data transfer fast and easy Image processing tools highlight data by removing grid lines and backgrounds Status bar suggestions guide beginners Context sensitive popup help windows reveal explain feature of the user interface Tutorials with pictures explain strategies for common operations Browser-based user manual is extensive yet easy to navigate Preview windows give immediate feedback while modifying settings Dates and times are imported with the Date/Time Converter Import support for common image file formats such as BMP, GIF, JPEG, PNG and XPM Export support for common software packages such as Microsoft Excel, OpenOffice CALC, gnuplot, gnumeric, MATLAB and Mathematica Engauge is available for a wide variety of platforms (Linux, Mac OSX, Windows) Engauge Digitizer is completely open source and free courtesy of Sourceforge, Trolltech and FFTW

    This library is written in Modelica. The purpose of this library is to calculate fluid properties from an equation of state (EoS), directly within Modelica and not from an external dll. It supports EoS of the form f=f(T,d) meaning Helmholtz energy as a funtion of temperature and density. In addition to all state properties, this library calculates viscosity, thermal conductivity and surface tension. So far, the fluids n-Butane, R134a and Isobutane are implemented, but not fully validated. The next fluids to be implemented are probably isopentane, propane, ammonia, CO2 and other possible working fluids for Organic-Rankine-Cycles.

    MinGW, a contraction of "Minimalist GNU for Windows", is a minimalist development environment for native Microsoft Windows applications. MinGW provides a complete Open Source programming tool set which is suitable for the development of native MS-Windows applications, and which do not depend on any 3rd-party C-Runtime DLLs. (It does depend on a number of DLLs provided by Microsoft themselves, as components of the operating system; most notable among these is MSVCRT.DLL, the Microsoft C runtime library. Additionally, threaded applications must ship with a freely distributable thread support DLL, provided as part of MinGW itself). MinGW compilers provide access to the functionality of the Microsoft C runtime and some language-specific runtimes. MinGW, being Minimalist, does not, and never will, attempt to provide a POSIX runtime environment for POSIX application deployment on MS-Windows. If you want POSIX application deployment on this platform, please consider Cygwin instead. Primarily intended for use by developers working on the native MS-Windows platform, but also available for cross-hosted use, (see note below -- you may need to follow the "read more" link to see it), MinGW includes: A port of the GNU Compiler Collection (GCC), including C, C++, ADA and Fortran compilers; GNU Binutils for Windows (assembler, linker, archive manager) A graphical and a command-line installer for MinGW and MSYS deployment on MS-Windows MSYS, a contraction of "Minimal SYStem", is a Bourne Shell command line interpreter system. Offered as an alternative to Microsoft's cmd.exe, this provides a general purpose command line environment, which is particularly suited to use with MinGW, for porting of many Open Source applications to the MS-Windows platform; a light-weight fork of Cygwin-1.3, it includes a small selection of Unix tools, chosen to facilitate that objective, and using it is a necessary prerequisite for building mingwPORTs. mingwPORTs are user contributed additions to the MinGW software collection. Rather than providing these "add-ons" as precompiled binary packages, they are supplied in the form of interactive Bourne shell scripts, which guide the end user through the process of automatically downloading and patching original source code, then building and installing it. Users who wish to build any application from a mingwPORT must first install both MinGW and MSYS.

    SimulationX is a graphically-interactive tool for the holistic modeling, simulation and analysis of multi-domain systems from 1D to 3D. Multi-level customizing options and SimulationX’s capability to adjust the model’s complexity by mouse-click allow modeling in every step of the design process. Ready-to-use model libraries, e.g., for mechanics, multi-body systems, power transmission, hydraulics, pneumatics, thermodynamics, and electric drives are written in Modelica language. Libraries are extendable by Modelica-based modeling using the SimulationX TypeDesigner. A comprehensive API supports the integration into any CAE, CFD, CAD or database tool environment. Versatile interfaces offer plenty of opportunities for exporting models in terms of Simulink S-function and C-Code for HiL, RCP and other real-time applications. Different features (tracing, performance analyzer, switchable model complexity) support users in achieving real-time-capabilities.

    TeXstudio is a fork of the LaTeX IDE TexMaker and gives you an environment where you can easily create and manage LaTeX documents. It provides modern writing support, like interactive spell checking, code folding and syntax highlighting. Also it serves as a starting point from where you can easily run all necessary LaTeX tools. (you can see more features below) You can run it on Windows, Unix/Linux, BSD and MacOSX systems and modify it if you want, since it is licensed under the GPL. Althought TeXstudio has a lot of additional features, it tries to be like an improved version of Texmaker, so it keeps it look&feel as well as its version number.

    Desinfec’t ist eine auf Linux basierte Live-CD zur Desinfektion von Rechnersystemen nach einem Virenbefall. Sie wird von der c’t-Redaktion als Heftbeigabe zu regulären c’t-Ausgaben wie auch zu c’t-Sonderheften herausgegeben und in regelmäßigen Abständen aktualisiert. Bis 2009 trug die Distribution den Namen Knoppicillin. Konzept Das Konzept, den Virenscanner von einer Boot-CD zu starten, stellt sicher, dass die Betriebssystemumgebung des Scanners nicht verseucht sein kann. Ein Schädling kann so weder den Scanner selbst manipulieren, noch sich mit Funktionalitäten eines Rootkits unsichtbar machen, da sein Programmcode nicht während des Systemstarts von der Festplatte ausgeführt wurde. Ebenso kann er sich beispielsweise nicht in den Arbeitsspeicher kopieren und von dort aus erneut das System infizieren. Außerdem ist es von einer Live-CD auch dann noch möglich, das System zu booten, wenn eine Vireninfektion dies beim normalen Betriebssystem verhindert. Desinfec’t ist damit ein wirksames Mittel bei einem Befall mit Schädlingen mit Rootkit-Eigenschaften, der mit herkömmlichen Virenscannern nicht aufgedeckt werden kann – bei anderen Rootkits kann es allerdings (im Gegensatz zu herkömmlichen Viren und Trojanern) sinnvoll sein, diese im aktiven System zu suchen, da ihre charakteristischen Eigenschaften nur dann erkannt werden können. Die modifizierte Linux-Distribution beinhaltet mehrere teils kommerzielle Virenscanner und Treiber für alle gängigen Dateisysteme. Damit ist Desinfec’t und dessen Vorgänger Knoppicillin in der Lage, auch NTFS-Partitionen zu durchsuchen und zu säubern. Eine Aktualisierung der Virensignaturen ist während der laufenden Session automatisch über das Internet oder manuell per Diskette und USB-Stick möglich oder man erstellt sich eine Kopie der CD und integriert dabei gleich aktuelle Virensignaturen. Knoppicillin basierte auf Knoppix als Distribution, woher sich auch der Name ableitet. Bei Desinfec’t wurde zunächst auf Fedora umgestellt, was jedoch von einigen Anwendern nicht gut aufgenommen wurde. Die zweite Desinfec’t-Veröffentlichung, Version 2011, setzt auf die Linux-Distribution Ubuntu. Wegen der Lizenzen einiger Virenscanner ist Desinfec’t nur kostenpflichtig erhältlich und Knoppicillin lässt sich in der recht alten Version 6.0.2 von 2008 nicht komplett herunterladen. Zudem ist bei einigen Virenscannern ein Aktualisieren nur bis zu einem Jahr nach Erscheinen der CD möglich.

    Sweave is a tool that allows to embed the R code for complete data analyses in latex documents. The purpose is to create dynamic reports, which can be updated automatically if data or analysis change. Instead of inserting a prefabricated graph or table into the report, the master document contains the R code necessary to obtain it. When run through R, all data analysis output (tables, graphs, etc.) is created on the fly and inserted into a final latex document. The report can be automatically updated if data or analysis change, which allows for truly reproducible research.

    SciPy (pronounced "Sigh Pie") is open-source software for mathematics, science, and engineering. It is also the name of a very popular conference on scientific programming with Python. The SciPy library depends on NumPy, which provides convenient and fast N-dimensional array manipulation. The SciPy library is built to work with NumPy arrays, and provides many user-friendly and efficient numerical routines such as routines for numerical integration and optimization. Together, they run on all popular operating systems, are quick to install, and are free of charge. NumPy and SciPy are easy to use, but powerful enough to be depended upon by some of the world's leading scientists and engineers. If you need to manipulate numbers on a computer and display or publish the results, give SciPy a try!

    WordPress.com is brought to you by some of the same folks who work on the open source blogging software available at WordPress.org. Open source WordPress has been incredibly successful and risen from a handful of users to the most-used blog tool in its category. However, as easy-to-use as we could make the open source package, there was still a barrier in that it requires a hosting account, a database, FTP, and a whole alphabet soup of acronyms that make normal people like you and me dizzy. We wanted to bring the WordPress experience to a larger audience. So we created WordPress.com, a hosted version of the open source package where you can start a blog in seconds without any technical knowledge. We’re a bit of an underdog, as there are much larger hosted blogging services such as Blogger that have been out for years, but when WordPress.org got started people said the blog software market was saturated and there wasn’t room for anything new. (The big players then were Greymatter and Movable Type.) We think we have something unique to bring to the table. WordPress.com is under very active development, and we roll out updates almost every day. New features and services are driven by you so please use our feedback form to let us know what you want. Almost everything on WordPress.com is free, and things that are currently free will remain free in the future, but we do offer paid a la carte upgrades for things like CSS editing and custom domains. How do we pay for everything? WordPress.com is run by Automattic which currently makes money from the aforementioned upgrades, blog services, Akismet anti-spam technology, and hosting partnerships. We know there are a lot of places you could put your blog, and we’d be extra honored if you consider us. If you’re a current user and you dig what we’re doing, the best way you can help us out is to help a friend get set up as well. It also gives you more buddies for your blogroll.

    CNRI Handle Extension for Firefox embeds a handle/DOI name resolver in the browser. It finds handles and DOI names used as references in web pages, in a variety of formats, sends them directly to the Handle System for resolution, and gets back current information about the identified entity, e.g., current location. The results of that handle resolution are used to determine browser behavior, e.g., display the current version of a document even if it has been moved since the creation of the reference. After installing this extension in your Firefox browser, you will be able to directly access handle URIs like hdl:4263537/4000 or Digital Object Identifier URIs like doi:10.1000/1 by typing them into the address bar, clicking on links with such references, or even having one as the source of an image. Your browser will resolve these handles using the native Handle System protocol. What's more, if you do follow a link to a web-to-handle proxy server (e.g., http://hdl.handle.net/4263537/4000 or http://dx.doi.org/10.1000/1), your browser will recognize this and use the native Handle System protocol instead. The extension will automatically detect if a firewall prevents direct handle resolution and will fall back to using a web-to-handle proxy server in that case. A configuration option can turn off redirecting to URLs embedded in the handle values, allowing you to examine the structure of the handle record.

    Mission The Thermophysical Properties Division provides the best available measurements, theory, computations, and data evaluation for the thermophysical property information required to enable development of standards, enhance productivity, facilitate trade, ensure scientific and technological progress, and improve the quality of life. Overview The Thermophysical Properties Division (TPD) was formed at the beginning of 2008 by a reorganization which separated the old Physical and Chemical Properties Division into two entities with distinct focuses and each housed on one of the two main campuses of NIST. The TPD is a Division of the Material Measurement Laboratory located on the Boulder campus. The Thermophysical Properties Division strives to be the foremost and best source of high quality thermophysical property information. This vision is driven by the ubiquitous importance of this information to commerce, industry, manufacturing, and national policy objectives. The Division meets its challenges through an integrated program of experimental measurement, data collection and evaluation, development of theoretically based models, and simulation of model systems. Among the outputs of the Division are computerized standard reference databases which synthesize thermophysical property information in forms which are conveniently used by our stakeholders. The vast majority of commodity exchanges in chemicals, energy related fluids, and materials are based on physical and chemical properties. In some cases, national and international standards for these properties are needed, such as the AGA-8 equation of state for the properties of natural gas, ASME-IAPWS Properties of Water and Steam, ISO-Standard Equations for refrigerants. Generally these standards are presented in the form of high accuracy equations of state which allow determination of a wide range of thermodynamic properties. Additionally, performance criteria of working fluids, feedstock, chemicals, and cryogenic systems are inextricably linked to thermophysical properties, e.g. density, viscosity, boiling point, phase behavior, heat capacity, stability, etc. Engineering design, optimal operation, and innovation for engines, chemical manufacturing, power generation, heating and air conditioning, distillation, etc. depends critically on knowledge of these properties. Reliable properties data are critical to competitive advantage, sustainability, and innovation. Finally, we note that widespread reliance of industry on properties information, success in setting and achieving national energy, environmental, and security goals often requires an extensive and trustworthy properties information-base. To meet the broad spectrum of needs, only briefly sketched above, the Division’s work is structured along four synergistic themes: * Develop and maintain the measurement capabilities, standard materials and reference data needed to underpin a national system of thermophysical property measurements; * Develop large-scale, readily accessible data resources providing trustworthy property information meeting high priority needs for a broad range of industries and national agendas; * Develop empirical and fundamental predictive capabilities to enable reliable estimation of property values when experimental data are unavailable; Research experimental techniques and address key data-gaps in support of specific, high priority industrial and national initiatives. These themes allow effective response to customer needs and are consistent with the Division’s operating strategy to maintain a highly synergistic research program that includes an appropriate balance of measurement, theory, and predictive models. The combination of the Division’s world class expertise and unrivaled resources in measurement, archiving, and provision of high-quality property data is complemented by its forefront research to develop reliable and highly adaptable methods for estimating property data in cases where measurements are unavailable or extremely difficult and/or costly to obtain. Core Expertise The expertise in the Division is broadly distributed within the fields of thermophysical properties and processes, emphasizing (1) data infrastructure and access; (2) predictive theory and models; and (3) experimental tools and measurements. More specifically, the Division maintains competence in data evaluation and dissemination; property models for industrial use; measurement of thermophysical properties; cryogenic technologies; separation technologies; fuel properties; and properties for environmental chemistry. Key Interactions with Customers Division outputs are routinely used in a variety of industrial, governmental, and academic settings. For instance, through a collaboration with Aspen Technology, evaluated data from the NIST Thermodynamic Data Engine are available to some 60,000 chemical plants world-wide. A consortium of chemical and related companies provides direct input to the data collection and evaluation programs of the Thermodynamic Research Center Group. The NIST REFPROP database was purchased by some 1200 customers in 2008, and all cryogenic flow meters in the U.S. are tied to the Division’s calibration and testing services. The Division houses the editorial offices of the International Journal of Thermophysics (and provides an editor of the Journal of Physical and Chemical Reference Data) and organizes the triennial Symposium on Thermophysical Properties to maintain connections. Sponsored research in the Division also provides direct links to key customers: work with DOD (primarily the Air Force) is important to our fuels program; DHS funds some of our work on properties and data for explosives; DARPA works with the Division in its micro-cryocooler project; DOE is engaged in our properties work related to advanced power generation and in gas hydrates data. Future Directions and Plans The National challenges related to energy security and monitoring/mitigating anthropogenic climate (or other environmental) changes are reflected in the Division’s plans. The Division recently held workshops on property needs for biofuels and aerospace fuels: alternative fuels and feedstocks will command an increased emphasis in the future.

    LyX is a document processor that encourages an approach to writing based on the structure of your documents (WYSIWYM) and not simply their appearance (WYSIWYG). LyX combines the power and flexibility of TeX/LaTeX with the ease of use of a graphical interface. This results in world-class support for creation of mathematical content (via a fully integrated equation editor) and structured documents like academic articles, theses, and books. In addition, staples of scientific authoring such as reference list and index creation come standard. But you can also use LyX to create a letter or a novel or a theatre play or film script. A broad array of ready, well-designed document layouts are built in. LyX is for people who want their writing to look great, right out of the box. No more endless tinkering with formatting details, “finger painting” font attributes or futzing around with page boundaries. You just write. On screen, LyX looks like any word processor; its printed output — or richly cross-referenced PDF, just as readily produced — looks like nothing else.

    Gene Expression Programming (GEP) is a new evolutionary algorithm that evolves computer programs (they can take many forms: mathematical expressions, neural networks, decision trees, polynomial constructs, logical expressions, and so on). The computer programs of GEP, irrespective of their complexity, are all encoded in linear chromosomes. Then the linear chromosomes are expressed or translated into expression trees (branched structures). Thus, in GEP, the genotype (the linear chromosomes) and the phenotype (the expression trees) are different entities (both structurally and functionally), and because of this apparently trivial fact, this new evolutionary system can finally make a difference, successfully assisting researchers in the design of robust and accurate computer models. As in nature, the linear chromosomes of GEP consist of the genetic material that is passed on with modification to the next generation. This, in other words, means that in GEP all the genetic modifications take place in the linear chromosomes (much easier to do than in complex branched structures as is done in GP), and it also means that only the linear chromosomes are transmitted in the process of reproduction (linear strings are much easier to replicate than complicated tree structures). And also as in nature, it's only during development that the information encoded in the chromosomes is finally expressed into fully developed computer programs or expression trees (ETs). Expression trees are sophisticated computer programs that are usually evolved to solve a particular problem and are therefore selected according to their fitness at solving that task. With time, populations of such computer programs (encoded, of course, in linear chromosomes) will discover new traits (thanks to genetic modification) and therefore will become better adapted to the particular environment chosen for their breeding (this environment defines obviously the problem at hand). And this means that, given enough time and that we've set the stage correctly, a good solution to the problem at hand will be discovered. So, GEP is a full-fledged genotype/phenotype system, with the genotype totally separated from the phenotype. In Genetic Programming, though, we have a totally different scenario: genotype and phenotype are one entangled mess or what is more formally called a simple replicator system. And the consequences of this are huge: the full-fledged genotype/phenotype system of GEP surpasses the old GP system by a factor of 100-60,000!

People trying things just to see what happens. Those are all phrases that could be applied to KDE - or to scientists.

    Evocosm is a set of classes that abstract the fundamental components of an evolutionary algorithm. I'll list the components here with a bit of introduction; you can review the details of the classes by downloading the code archives or by reviewing the online documentation (see the menu at the article's beginning for code and documentation links.) All class documentation was generated from source code comments using doxygen. These docs have not been thoroughly proofread, so they may contain a few typos and minor errors. Self-publishing has taught me the value of a good proofreader... ;} Evolutionary algorithms come in a variety of shapes and flavors, but at their core, they all share certain characteristics: populations that reproduce and mutate through a series of generations, producing future generations based on some measure of fitness. An amazing variety of algorithms can be built on that general framework, which leads me to construct a set of core classes as the basis for future applications.

    EvA2 (an Evolutionary Algorithms framework, revised version 2) is a comprehensive heuristic optimization framework with emphasis on Evolutionary Algorithms implemented in Java. It is a revised version of the JavaEvA optimization toolbox, which has been developed as a resumption of the former EvA software package. EvA2 integrates several derivation free optimization methods, preferably population based, such as Evolution Strategies (ES), Genetic Algorithms (GA), Differential Evolution (DE), Particle Swarm Optimization (PSO), as well as classical techniques such as multi-start Hill Climbing or Simulated Annealing. Besides typical single-objective problems, multi-modal and multi-objective problem are handled directly by the EvA2 framework. Via the Java mechanism of Remote Method Invocation (RMI), the algorithms of EvA2 can be distributed over network nodes based on a client-server architecture. EvA2 aims at two groups of users. Firstly, the end user who does not know much about the theory of Evolutionary Algorithms, but wants to use Evolutionary Algorithms to solve an application problem. Secondly, the scientific user who wants to investigate the performance of different optimization algorithms or wants to compare the effect of alternative or specialized evolutionary or heuristic operators. The latter usually knows more about evolutionary algorithms or heuristic optimization and is able to extend EvA2 by adding specific optimization strategies or solution representations. EvA2 is being used as teaching aid in lecture tutorials, as a developing platform in student research projects and applied to numerous optimisation problems within active research and ongoing industrial cooperations.

    digiKam is an advanced digital photo management application for KDE, which makes importing and organizing digital photos a "snap". The photos are organized in albums which can be sorted chronologically, by folder layout or by custom collections. Tired of the folder constraints? Don’t worry, digiKam also provides tagging. You tag your images which can be spread out across multiple folders, and digiKam provides fast and intuitive ways to browse these tagged images. You can also add comments to your images. digiKam makes use of a fast and robust database to store these meta-informations which makes adding and editing of comments and tags very reliable. digiKam makes use of KIPI plugins for lots of added functionality. KIPI (KDE Image Plugin Interface) is an initiative to create a common plugin infrastructure for digiKam, KPhotoAlbum, Showimg, and GwenView. Its aim is to allow development of image plugins which can be shared among KDE graphical applications. An easy-to-use interface is provided that enables you to connect to your camera and preview, download and/or delete your images. Basic auto-transformations can be deployed on the fly during image downloading. Another tool, which most artists and photographers will be familiar with, is a Light Table. This tool assists artists and photographers with reviewing their work ensuring the highest quality only. A classical light table will show the artist the place on the images to touch up. Well in digiKam, the light table function provides the user a similar experience. You can import a photo, drag it onto the light table, and touch up only the areas that need it. The digiKam Image Editor has its own plugin subsystem with some common tools e.g. red eye correction or Gamma correction. Additional plugins are provided with the main application to process advanced corrections on image like color management, noise reduction, or special effects. digiKam Image Editor supports all camera RAW file formats, 16 bits color depth, Exif/Makernote/IPTC/GPS/XMP metadata, Color management, tagging/rating/comments pictures, etc. A stand-alone image editor version named ShowFoto is also available. It runs without digiKam images database support, but provides all Image Editor functions.

    Git is distributed version control system focused on speed, effectivity and real-world usability on large projects. Its highlights include: * Distributed development. Like most other modern version control systems, Git gives each developer a local copy of the entire development history, and changes are copied from one such repository to another. These changes are imported as additional development branches, and can be merged in the same way as a locally developed branch. Repositories can be easily accessed via the efficient Git protocol (optionally wrapped in ssh for authentication and security) or simply using HTTP - you can publish your repository anywhere without any special webserver configuration required. * Strong support for non-linear development. Git supports rapid and convenient branching and merging, and includes powerful tools for visualizing and navigating a non-linear development history. * Efficient handling of large projects. Git is very fast and scales well even when working with large projects and long histories. It is commonly an order of magnitude faster than most other version control systems, and several orders of magnitude faster on some operations. It also uses an extremely efficient packed format for long-term revision storage that currently tops any other open source version control system. * Cryptographic authentication of history. The Git history is stored in such a way that the name of a particular revision (a "commit" in Git terms) depends upon the complete development history leading up to that commit. Once it is published, it is not possible to change the old versions without it being noticed. Also, tags can be cryptographically signed. * Toolkit design. Following the Unix tradition, Git is a collection of many small tools written in C, and a number of scripts that provide convenient wrappers. Git provides tools for both easy human usage and easy scripting to perform new clever operations. Besides providing a version control system, the Git project provides a generic low-level toolkit for tree history storage and directory content management. Traditionally, the toolkit is called the plumbing. Aside the user interface coming with Git itself, several other projects (so-called porcelains) offer compatible version control interfaces - see the related tools list.

    Subversion is a full-featured version control system originally designed to be a better CVS. Subversion has since expanded beyond its original goal of replacing CVS, but its basic model, design, and interface remain heavily influenced by that goal. Even today, Subversion should still feel very familiar to CVS users. The following list of features is presented with the assumption that you, the reader, have a basic understanding of what version control is and how version control systems work in general. If there's a feature that you're looking for that is not represented in this list, feel free to ask about it on our project mailing lists — perhaps we just didn't think to list it here. If Subversion truly lacks a feature you need, your feedback will help us to improve Subversion, and in the meantime, perhaps we can help you meet your need with the features that Subversion does have. * Most CVS features. ¶ CVS is a relatively basic version control system. For the most part, Subversion has matched or exceeded CVS's feature set where those features continue to apply in Subversion's particular design. * Directories are versioned. ¶ Subversion versions directories as first-class objects, just like files. * Copying, deleting, and renaming are versioned. ¶ Copying and deleting are versioned operations. Renaming is also a versioned operation, albeit with some quirks. * Free-form versioned metadata ("properties"). ¶ Subversion allows arbitrary metadata ("properties") to be attached to any file or directory. These properties are key/value pairs, and are versioned just like the objects they are attached to. Subversion also provides a way to attach arbitrary key/value properties to a revision (that is, to a committed changeset). These properties are not versioned, since they attach metadata to the version-space itself, but they can be changed at any time. * Atomic commits. ¶ No part of a commit takes effect until the entire commit has succeeded. Revision numbers are per-commit, not per-file, and commit's log message is attached to its revision, not stored redundantly in all the files affected by that commit. * Branching and tagging are cheap (constant time) operations. ¶ There is no reason for these operations to be expensive, so they aren't. Branches and tags are both implemented in terms of an underlying "copy" operation. A copy takes up a small, constant amount of space. Any copy is a tag; and if you start committing on a copy, then it's a branch as well. (This does away with CVS's "branch-point tagging", by removing the distinction that made branch-point tags necessary in the first place.) * Merge tracking. ¶ Subversion 1.5 introduces merge tracking: automated assistance with managing the flow of changes between lines of development, and with the merging of branches back into their sources. The 1.5 release of merge tracking has basic support for common scenarios; we will be extending the feature in upcoming releases. * File locking. ¶ Subversion supports (but does not require) locking files so that users can be warned when multiple people try to edit the same file. A file can be marked as requiring a lock before being edited, in which case Subversion will present the file in read-only mode until a lock is acquired. * Symbolic links can be versioned. ¶ Unix users can place symbolic links under version control. The links are recreated in Unix working copies, but not in win32 working copies. * Executable flag is preserved. ¶ Subversion notices when a file is executable, and if that file is placed into version control, its executability will be preserved when it it checked out to other locations. (The mechanism Subversion uses to remember this is simply versioned properties, so executability can be manually edited when necessary, even from a client that does not acknowledge the file's executability, e.g., when having the wrong extension under Microsoft Windows). * Apache network server option, with WebDAV/DeltaV protocol. ¶ Subversion can use the HTTP-based WebDAV/DeltaV protocol for network communications, and the Apache web server to provide repository-side network service. This gives Subversion an advantage over CVS in interoperability, and allows certain features (such as authentication, wire compression) to be provided in a way that is already familiar to administrators * Standalone server option (svnserve). ¶ Subversion offers a standalone server option using a custom protocol, since not everyone wants to run an Apache HTTPD server. The standalone server can run as an inetd service or in daemon mode, and offers the same level of authentication and authorization functionality as the HTTPD-based server. The standalone server can also be tunnelled over ssh. * Parseable output. ¶ All output of the Subversion command-line client is carefully designed to be both human readable and automatically parseable; scriptability is a high priority. * Localized messages. ¶ Subversion uses gettext() to display translated error, informational, and help messages, based on current locale settings. * Interactive conflict resolution. ¶ The Subversion command-line client (svn) offers various ways to resolve conflicting changes, include interactive resolution prompting. This mechanism is also made available via APIs, so that other clients (such as graphical clients) can offer interactive conflict resolution appropriate to their interfaces. * Repository read-only mirroring. ¶ Subversion supplies a utility, svnsync for synchronizing (via either push or pull) a read-only slave repository with a master repository. * Write-through proxy over WebDAV. ¶ Subversion 1.5 introduces a write-through proxy feature that allows slave repositories (see read-only mirroring) to handle all read operations themselves while passing write operations through to the master. This feature is only available with the Apache HTTPD (WebDAV) server option. * Natively client/server, layered library design with clean APIs. ¶ Subversion is designed to be client/server from the beginning; thus avoiding some of the maintenance problems which have plagued CVS. The code is structured as a set of modules with well-defined interfaces, designed to be called by other applications. * Binary files handled efficiently. ¶ Subversion is equally efficient on binary as on text files, because it uses a binary diffing algorithm to transmit and store successive revisions. * Costs are proportional to change size, not data size. ¶ In general, the time required for a Subversion operation is proportional to the size of the changes resulting from that operation, not to the absolute size of the project in which the changes are taking place. * Bindings to programming languages. ¶ The Subversion APIs come with bindings for many programming languages, such as Python, Perl, Java, and Ruby. (Subversion itself is written in C.) * Changelists. ¶ Subversion 1.5 introduces changelists, which allows a user to put modified files into named groups on the client side, and then commit by specifying a particular group. For those who work on logically separate changesets simultaneously in the same directory tree, changelists can help keep things organized.

    gPROMS is an equation-oriented modelling system used for building, validating and executing first-principles models within a flowsheeting framework. Models are constructed in the gPROMS ModelBuilder by writing down the fundamental chemistry, physics, chemical engineering, operating procedures and other relationships that govern the process or product behaviour. The resulting model is then validated against observed data — typically, laboratory, pilot plant or operating data — to adjust model parameters such as heat transfer coefficients to match reality as closely as possible. Of course, you don't need to create a model from scratch every time – you can use one of the many state-of-the-art gPROMS model libraries, or create your own library for publishing throughout your organisation. Solution accuracy – for multiple applications The first-principles approach combined with rigorous validation results in models of unprecedented accuracy. Once a model exists, it can be solved in many different ways to perform many different activities – for example, steady-state simulation, dynamic simulation, parameter estimation, model-based experiment design, steady-state and dynamic optimisation, including integer optimisation, or generation of linearised models for use in control and online optimisation, across the process lifecycle. This means that once you have invested in creating an accurate gPROMS model of your process you can use that model wherever it can generate value, to ensure multiple return on investment. PSE ModelCare PSE recognises that creating high-accuracy process models requires expertise in many different domains – chemical engineering, physics, chemistry, hydrodynamics and modelling and numerical solution itself. That is why we provide the ModelCare service. ModelCare aims to help companies deliver fit-for purpose modelling applications rapidly, while transferring modelling know-how to customer organisations.

    R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control. R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.

      PSPP is a program for statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functionality that PSPP currently supports is in the core package. PSPP can perform descriptive statistics, T-tests, linear regression and non-parametric tests. Its backend is designed to perform its analyses as fast as possible, regardless of the size of the input data. You can use PSPP with its graphical interface or the more traditional syntax commands.

      LAPACK is written in Fortran90 and provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision. If you're uncertain of the LAPACK routine name to address your application's needs, check out the LAPACK Search Engine. The original goal of the LAPACK project was to make the widely used EISPACK and LINPACK libraries run efficiently on shared-memory vector and parallel processors. On these machines, LINPACK and EISPACK are inefficient because their memory access patterns disregard the multi-layered memory hierarchies of the machines, thereby spending too much time moving data instead of doing useful floating-point operations. LAPACK addresses this problem by reorganizing the algorithms to use block matrix operations, such as matrix multiplication, in the innermost loops. These block operations can be optimized for each architecture to account for the memory hierarchy, and so provide a transportable way to achieve high efficiency on diverse modern machines. We use the term "transportable" instead of "portable" because, for fastest possible performance, LAPACK requires that highly optimized block matrix operations be already implemented on each machine. LAPACK routines are written so that as much as possible of the computation is performed by calls to the Basic Linear Algebra Subprograms (BLAS). While LINPACK and EISPACK are based on the vector operation kernels of the Level 1 BLAS, LAPACK was designed at the outset to exploit the Level 3 BLAS -- a set of specifications for Fortran subprograms that do various types of matrix multiplication and the solution of triangular systems with multiple right-hand sides. Because of the coarse granularity of the Level 3 BLAS operations, their use promotes high efficiency on many high-performance computers, particularly if specially coded implementations are provided by the manufacturer. Highly efficient machine-specific implementations of the BLAS are available for many modern high-performance computers. For details of known vendor- or ISV-provided BLAS, consult the BLAS FAQ. Alternatively, the user can download ATLAS to automatically generate an optimized BLAS library for the architecture. A Fortran77 reference implementation of the BLAS in available from netlib; however, its use is discouraged as it will not perform as well as a specially tuned implementation.
