Applied Research Laboratories, The University of Texas at Austin (ARL:UT) has established a cross platform open source software project called the GPSTk or the GPS Toolkit. The GPSTk consists of a library and collection of applications that support GPS research, analysis, and development. The code is released under the terms of the Lesser GNU Public License. The GPSTk supports a broad range of functionality. This includes reading and writing observations in standard formats, such as RINEX, BINEX, and SP3, ephemeris evaluation, position determination, receiver autonomous integrity monitoring (RAIM), atmospheric delay modeling, cycle slip detection and correction, and P-code generation. The GPSTk provides the core set of functionality that is used for GPS research and development at ARL:UT. ARL:UT has been involved with satellite navigation since Transit (the precursor to GPS) in the 1960s and is currently conducting research in a wide variety of GPS-related fields, including precise surveys, monitor station networks, and ionospheric studies. The GPSTk is a community-wide resource for all users of GPS and GNSS technology. Participation is welcomed in all areas including: bug reports, new algorithms, suggestions for improvement, and contributions of additional functionality or applications. ARL:UT continually improves the library, shepherds community participation, and is committed to the project's development and maintenance.The GPS Toolbox is a column dedicated to highlighting algorithms and source code utilized by GPS Engineers and scientists. If you have an interesting program or software package you would like to share with our readers, please pass it along; e-mail it to us at gps-toolbox@ngs.noaa.gov.

AbstraktProcesní analýza a modelování byznys procesů je jedna z významných částí aplikované (byznys) informatiky. Kvalita byznys procesů (diagramů) je v této oblasti velmi důležitá. Cílem každého procesního analytika by měla být tvorba srozumitelných, jednoznačných a bezchybných procesních diagramů. Pokud je proces řádně popsán, lze jej využít jako vstup pro detailnější analýzu a optimalizaci. Lze předpokládat, že řádně vytvořený a popsaný diagram byznys procesu (obdobně jako řádně napsaný algoritmus) bude obsahovat charakteristiky, které lze matematicky popsat. Kromě toho by bylo možné vytvořit nástroj, který by pomohl procesním analytikům vytvářet vhodné procesní diagramy. V rámci tohoto přehledového článku bude realizována rešerše dostupné literatury, jejíž cílem je nalezení a následné provedení analýzy míry návrhu a kvality byznys procesů. Rešerší bylo nalezeno, že zmíněná oblast již byla předmětem výzkumu. Bylo nalezeno třicet tři vědeckých publikací a dvacet dva měr kvality. Závěrem lze říci, že nalezené vědecké publikace a míry kvality nereflektují všechny důležité atributy jasnosti, jednoduchosti a úplnosti modelů byznys procesů. Z toho důvodu by bylo vhodné obohatit existující míry kvality diagramů byznys procesů.Klíčová slova: Modelování byznys procesů, analýza byznys procesů, byznys procesy, míry kvality, BPMN. AbstractBusiness process modelling and analysing is undoubtedly one of the most important parts of Applied (Business) Informatics. Quality of business process models (diagrams) is crucial for any purpose in this area. The goal of a process analyst's work is to create generally understandable, explicit and error free models. If a process is properly described, created models can be used as an input into deep analysis and optimization. It can be assumed that properly designed business process models (similarly as in the case of correctly written algorithms) contain characteristics that can be mathematically described. Besides it will be possible to create a tool that will help process analysts to design proper models. As part of this review will be conducted systematic literature review in order to find and analyse business process model's design and business process model's quality measures. It was found that mentioned area had already been the subject of research investigation in the past.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
