Abstract. This paper presents Shyft, a novel hydrologic modeling software for streamflow forecasting targeted for use in hydropower production environments and research. The software enables rapid development and implementation in operational settings and the capability to perform distributed hydrologic modeling with multiple model and forcing configurations. Multiple models may be built up through the creation of hydrologic algorithms from a library of well-known routines or through the creation of new routines, each defined for processes such as evapotranspiration, snow accumulation and melt, and soil water response. Key to the design of Shyft is an application programming interface (API) that provides access to all components of the framework (including the individual hydrologic routines) via Python, while maintaining high computational performance as the algorithms are implemented in modern C++. The API allows for rapid exploration of different model configurations and selection of an optimal forecast model. Several different methods may be aggregated and composed, allowing direct intercomparison of models and algorithms. In order to provide enterprise-level software, strong focus is given to computational efficiency, code quality, documentation, and test coverage. Shyft is released open-source under the GNU Lesser General Public License v3.0 and available at https://gitlab.com/shyft-os (last access: 22 November 2020), facilitating effective cooperation between core developers, industry, and research institutions.

Comprehensive Study

The article is devoted to the comprehensive study of the professional information needs (IN) of specialists of the central libraries of the subjects of the Russian Federation. The rapid development of high technologies in the field of accumulation, transmission and processing of information, the creation of modern telecommunications systems have led to the emergence of fundamentally new opportunities for organizing the information process. This, in turn, led to the qualitative growth of IN specialists, including those employed in the field of library activities. The specific features of IN library specialists are determined by their place and role in the modern process of cultural activity, industry orientation, nature of work and specialization. During 2018—2019, the Centre for Research of Problems of the Development of Libraries in the Information Society of the Russian State Library carried out research aimed at comprehensive study of the information needs of cultural workers employed in the library sphere. At the first stage of the research, there was comprehended the existing experience of studying professional information needs in the national library science. At the second stage, using the method of questionnaire survey, information needs of library specialists were studied in order to identify the most rational forms and methods of providing them. The analysis of the survey results made it possible to identify the sources of professional information, to reveal information resources that have the greatest importance and characterize specific features of librarians’ information needs.The author concludes on the need to expand the access to full-text databases and electronic versions of periodicals for library staff. The creation of integrated information centre could help providing library professionals with professional information. Currently, the function of such a centre is performed by the National Electronic Library, which includes the professional section for library specialists. The results of the study form theoretical and methodological basis for the rational use of resources and potential of libraries in providing information to professional information needs of library specialists and determine the prospects for further research related to improving the forms and methods of information service for this category of users.

The Creation

The rapid development of complex virtual worlds (most notably, in 3D computer and video games) introduces new challenges for the creation of virtual agents, controlled by artificial intelligence (AI) systems. Two important subproblems in this topic area which need to be addressed are (a) believability and (b) effectiveness of agents’ behavior, i.e., human-likeness of the characters and high ability to achieving their own goals. In this paper, the authors study current approaches to believability and effectiveness of AI behavior in virtual worlds. They examine the concepts of believability and effectiveness, and analyze several successful attempts to address these challenges.

The topicality of the article is determined by the fact that it examines the specifics of modern digital content in the context of the transformation processes, which take place in modern media in the context of transmedia that influence the formation of digital etiquette. The rapid development of the technical and technological components of communication contributes to the constant transformation of digital etiquette and this is one of the problems of modern transmedia space, which actualizes the identification of the content features of digital content, the role of the axiological component of modern media materials, the definition of effective ways of their representation that corresponds with the needs of the modern digital audience. The aim of the research is to describe the key characteristics of digital content in modern media that promote the formation of digital etiquette. The novelty of the article is in the concept analysis of print media, television and radio broadcasting in the context of transmedia according to the approach of the general key characteristics of the current digital content that contribute to the formation of digital etiquette and have the prospect of further research. The methodological basis was the scientific works of media theorists in Russian and foreign scientific communities. During the work on the article in the field of researching the content of modern mass media and the transformation processes that take place in the media, the author used the methods of analysis and comparison, the synthesis method was applied in terms of discussing the research results, formulating conclusions. The results of the research show that today not only adaptation in the digital environment is required but also close integration with all processes of the digital development of society is necessary for the successful functioning of modern media. The typical key features for modern digital content, which are the environment for the formation of digital etiquette, were identified during the research. It includes the ability to consume content through various gadgets; creation of interactive materials that satisfy the demands of a certain audience and give the right to participate in the creation of content and to choose it; the creation of complex multi-component materials that are endowed with the features of the project and also the transmedia narrative pattern. The article represents the interest to practicing journalists, as well as to researchers in the sphere of development of digital journalism, transmedia storytelling, digital content features and digital etiquette.

The Creation

The rapid development of the IT world has covered all aspects of life and among IT technology products is the creation of Operating Systems and Web browser applications. Privacy in the use of IT in the open era is now highly expected, therefore now widely developed Operating Systems and Web browser applications that have facilities to protect user privacy. Linux and TOR Browser is a combination that is widely used in the field of security, but unfortunately many are misused by the person in a crime. The motivation to use both is to eliminate or minimize the digital footprint of the browsing activity so that it will complicate the search of digital evidence in a crime. This research proposes a framework of stages for TOR Browser analysis in Linux Operating System which aims to provide solution in forensic investigation using offline forensic method. The use of offline forensic methods to obtain detailed information from a digital proof on a computer in a off state
