Non-Specialized File Format Extension  [PDF]
Blake W. Ford & Khosrow Kaikhah
International Journal of Computer Science and Security , 2011,
Abstract: The study expands upon previous work in format extension. The initial research purposed extraspace provided by an unrefined format to store metadata about the file in question. This processdoes not negatively impact the original intent of the format and allows for the creation of newderivative file types with both backwards compatibility and new features. The file format extensionalgorithm has been rewritten entirely in C++ and is now being distributed as an open sourceC/C++ static library, roughdraftlib. The files from our previous research are essentially binarycompatible though a few extra fields have been added for developer convenience. The new datarepresents the current and oldest compatible versions of the binary and values representing thescaling ratio of the image. These new fields are statically included in every file and take only afew bytes to encode, so they have a trivial effect on the overall encoding density.
BIOFFORC: Tool development for biological file format conversion  [cached]
Chinnaiah Swaminathan Vinobha,Maruthamuthu Rajadurai,Ekambaram Rajasekaran
Bioinformation , 2008,
Abstract: The use of bioinformatics tools require different sequence formats at various instances. Every tool uses specific set of formats for processing. Sequence in one format is often required in another format. Thus, there is a need for sequence format conversion. A number of such tools are available in the public domain. Here, we describe BIOFFORC as a file format converter. The tool is developed with a graphical user interface in PERL.
Static Analysis of File-Processing Programs using File Format Specifications  [PDF]
Raveendra Kumar Medicherla,Raghavan Komondoor,S. Narendran
Computer Science , 2015,
Abstract: Programs that process data that reside in files are widely used in varied domains, such as banking, healthcare, and web-traffic analysis. Precise static analysis of these programs in the context of software verification and transformation tasks is a challenging problem. Our key insight is that static analysis of file-processing programs can be made more useful if knowledge of the input file formats of these programs is made available to the analysis. We propose a generic framework that is able to perform any given underlying abstract interpretation on the program, while restricting the attention of the analysis to program paths that are potentially feasible when the program's input conforms to the given file format specification. We describe an implementation of our approach, and present empirical results using real and realistic programs that show how our approach enables novel verification and transformation tasks, and also improves the precision of standard analysis problems.
Specification of an extensible and portable file format for electronic structure and crystallographic data  [PDF]

Computer Science , 2008,
Abstract: In order to allow different software applications, in constant evolution, to interact and exchange data, flexible file formats are needed. A file format specification for different types of content has been elaborated to allow communication of data for the software developed within the European Network of Excellence "NANOQUANTA", focusing on first-principles calculations of materials and nanosystems. It might be used by other software as well, and is described here in detail. The format relies on the NetCDF binary input/output library, already used in many different scientific communities, that provides flexibility as well as portability accross languages and platforms. Thanks to NetCDF, the content can be accessed by keywords, ensuring the file format is extensible and backward compatible.
The QDF file format: an electronic system to describe ancient andean khipus  [PDF]
Manuel Arturo Izquierdo
Computer Science , 2005,
Abstract: With the goal of bringing to reseachers of the ancient andean khipus with a tool to share and process electronically the current corpus of these ancient information devices, I present on this paper a proposal for a Quipu Description Format (QDF), a XML based file format designed to describe such documents in a systematic and computer standard way.
Effects of Print Publication Lag in Dual Format Journals on Scientometric Indicators  [PDF]
Petr Heneberg
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0059877
Abstract: Background Publication lag between manuscript submission and its final publication is considered as an important factor affecting the decision to submit, the timeliness of presented data, and the scientometric measures of the particular journal. Dual-format peer-reviewed journals (publishing both print and online editions of their content) adopted a broadly accepted strategy to shorten the publication lag: to publish the accepted manuscripts online ahead of their print editions, which may follow days, but also years later. Effects of this widespread habit on the immediacy index (average number of times an article is cited in the year it is published) calculation were never analyzed. Methodology/Principal Findings Scopus database (which contains nearly up-to-date documents in press, but does not reveal citations by these documents until they are finalized) was searched for the journals with the highest total counts of articles in press, or highest counts of articles in press appearing online in 2010–2011. Number of citations received by the articles in press available online was found to be nearly equal to citations received within the year when the document was assigned to a journal issue. Thus, online publication of in press articles affects severely the calculation of immediacy index of their source titles, and disadvantages online-only and print-only journals when evaluating them according to the immediacy index and probably also according to the impact factor and similar measures. Conclusions/Significance Caution should be taken when evaluating dual-format journals supporting long publication lag. Further research should answer the question, on whether the immediacy index should be replaced by an indicator based on the date of first publication (online or in print, whichever comes first) to eliminate the problems analyzed in this report. Information value of immediacy index is further questioned by very high ratio of authors’ self-citations among the citation window used for its calculation.

Compatibility of Data Transfer between CAD Applications
H. Kuchynkova
Radioengineering , 2003,
Abstract: Compatibility of data transfers between individual CAD programs istopical when in another program we need to use a drawing or a 3D modelcreated in a program that uses a different modeling kernel. The papercharacterizes features and structures of existing CAD formats, problemsin their transfer, it notes the export/import conversion through theIGES, SAT, STEP and STL formats. It takes a closer look at using theSTL format for visualization and animation.
Dynamic Web File Format Transformations with Grace  [PDF]
Daniel S. Swaney,Frank McCown,Michael L. Nelson
Computer Science , 2005,
Abstract: Web accessible content stored in obscure, unpopular or obsolete formats represents a significant problem for digital preservation. The file formats that encode web content represent the implicit and explicit choices of web site maintainers at a particular point in time. Older file formats that have fallen out of favor are obviously a problem, but so are new file formats that have not yet been fully supported by browsers. Often browsers use plug-in software for displaying old and new formats, but plug-ins can be difficult to find, install and replicate across all environments that one may use. We introduce Grace, an http proxy server that transparently converts browser-incompatible and obsolete web content into web content that a browser is able to display without the use of plug-ins. Grace is configurable on a per user basis and can be expanded to provide an array of conversion services. We illustrate how the Grace prototype transforms several image formats (XBM, PNG with various alpha channels, and JPEG 2000) so they are viewable in Internet Explorer.

计算机应用 , 2008,
Abstract: STL is an Ad Hoc standard in rapid prototyping manufacturing. An efficient STL slicing algorithm is necessary for high quality prototype production. In this paper, we proposed a fast slicing algorithm based on recursion and searching direct graph with weight. In this method, the time consuming of creating direct graph was eliminated. Then the slicing data was postprocessed to get rid of the redundant points. Thus the slicing speed can be accelerated substantially. Lots of experiments and data analysis validate our new slicing algorithm.
