In this paper, the authors present the OpenWebGlobe project (http://www.openwebglobe.org). The authors also discuss the OpenWebGlobe SDK. OpenWebGlobe SDK is an open source framework for creating massive 3D virtual globe environments and interactively exploiting them in web browsers using HTML5 and WebGL, allowing for the creation of large scale virtual 3D globes with detailed contents and their interactive visualization directly within a broad spectrum of Web browsers.

AbstractThe PRISMS-Fatigue open-source framework for simulation-based analysis of microstructural influences on fatigue resistance for polycrystalline metals and alloys is presented here. The framework uses the crystal plasticity finite element method as its microstructure analysis tool and provides a highly efficient, scalable, flexible, and easy-to-use ICME community platform. The PRISMS-Fatigue framework is linked to different open-source software to instantiate microstructures, compute the material response, and assess fatigue indicator parameters. The performance of PRISMS-Fatigue is benchmarked against a similar framework implemented using ABAQUS. Results indicate that the multilevel parallelism scheme of PRISMS-Fatigue is more efficient and scalable than ABAQUS for large-scale fatigue simulations. The performance and flexibility of this framework is demonstrated with various examples that assess the driving force for fatigue crack formation of microstructures with different crystallographic textures, grain morphologies, and grain numbers, and under different multiaxial strain states, strain magnitudes, and boundary conditions.

Having already discussed MatConvNet and Keras, let us continue with an open source framework for deep learning, which takes a new and interesting approach. TensorFlow.js is not only providing deep learning for JavaScript developers, but it's also making applications of deep learning available in the WebGL enabled web browsers, or more specifically, Chrome, Chromium-based browsers, Safari and Firefox. Recently node.js support has been added, so TensorFlow.js can be used to directly control TensorFlow without the browser. TensorFlow.js is easy to install. As soon as a browser is installed one is ready to go. Browser based, cross platform applications, e.g. running with Electron, can also make use of TensorFlow.js without an additional install. The performance, however, depends on the browser the client is running, and memory and GPU on the client device. More specifically, one cannot expect to analyze 4K videos on a mobile phone in real time. While it's easy to install, and it's easy to develop based on TensorFlow.js, there are drawbacks: (i) developers have less control over where the machine learning actually takes place (e.g. on CPU or GPU), that it is running in the same sandbox as all web pages in the browser do, and (ii) that in the current release it still has rough edges and is not considered stable enough to use in production.

This article aims to bring on some enlightenment on the specifics of an experimental base formation for the creation of web maps dedicated to the French common youth slang. The relevance of the article is due to the pervasive nature of the French youth's “argotization” over the past two decades. The proposed study is devoted to the specifics of the formation of an experimental base for the creation of French common youth slang web maps, which will allow an illustration of the territorial localization of the slang (argotic) vocabulary. In this context, the authors elaborate preparatory procedures to form the basis for web mapping, namely the multistage processing of “argotographic data”, the inventory of core and peripheral “argotisms” and the verification of the identified linguistic facts under anti-epidemic restrictions on the mobility of scientists. The stages of the youth speech survey, which can be conducted remotely, are described. A review of lexicographic sources for the collection of argotic units is carried out. At the same time, the latest linguistic phenomenon of the French youth common slang (argot commun des jeunes) is briefly examined, and its relationship to the French common slang (argot commun) is described. The material of the study is youth argot lexemes collected from four traditional dictionaries and vocabulary lists of French and Russian eminent slang specialists (“argotologists”), four collaborative digital dictionaries, and two oral linguistic corpora. Youth argotisms are studied from the aspect of frequency parameters and the number of fixations in the argotographic sources. At the stage of collecting and identifying the elements of the common French youth slang vocabulary, several methods were applied: the method of sampling, the continuous sampling method, and the corpus linguistics method, including automated information extraction and the textual searches in large-scale corpora (concordances). At the stage of verification of the collected lexemes for their attribution to the French common youth slang, multiple crossed procedures were used: questionnaires, interviews, introspection, and “the initiated to the initiated” one. The present study was carried out in an experimental way, which, in turn, is applied in the research field on an actively developing social dialect.

In this paper, the open source framework NASA WorldWind is presented. NASA WorldWind comes with two versions. The Java version is well established in the market and has many customers. On the other side the new version, which is the Web version, Web WorldWind, is still at the dawn of development cycle, with many features implemented and already used in several applications, with a great future ahead. Moreover, some of the features available in the Web WorldWind are listed and a short comparison with Cesium library is provided. Additionally, an interesting application developed in the smart cities context with Web WorldWind is described.

Governments and their agencies are often challenged by high cost and flexible telephonic, Web based data services. Emerging technologies, such as those of Voice over Internet Protocol (VoIP) that allow convergent systems where voice and Web technologies can utilize the same network to provide both services, can be used to improve such services. This paper describe VoIP system for the enterprise network (e.g. company, university) that have been developed based on Asterisk which is a kind of open source software to implement IP-PBX system. Through the development and evaluation, we have confirmed that VoIP system based on Asterisk is very powerful as a whole and most PBX functions to be required for the enterprise network can be realized. Interesting findings include that the University of Kufa has a potential to implement the project. By connecting multiple Asterisk servers located in different sites based on IAX2, large scale enterprise network can be developed. Since the software recommended for installation is open source, the project could be used as a source of valuable information by students who specialize in real-time multi-media systems.
