Structural and functional model of formation of readiness of future specialists in computer technologies for professional activity by means of digital technologies

The article substantiates the structural and functional model of formation of the readiness of future specialists in computer technologies for professional activity by means of digital technologies. To achieve the goal of the article, the methodology is applied, which consists in conducting an analysis of the research of the problem of pedagogical modeling of the formation of the readiness of future specialists in computer technologies for professional activities in the field of digital technologies. On the basis of the conducted analysis, the concept of «structural-functional model», its structure and prospects of introduction into the educational process of future specialists in computer technologies are defined. It has been established that models in pedagogical science are successfully used for high-quality planning of the educational process, management of cognitive activity of students and optimization of the structure of educational material. In order to build a structural-functional model, its main constituent elements were determined, combined into logical blocks corresponding to the stages of the educational process (target, content, organizational, diagnostic-resultative) and complex application of modern digital technologies at all stages. The effectiveness of the implementation of the model was ensured by predefined organizational and pedagogical conditions

INNOVATIVE METHODS IN THE PROCESS OF HIGHER MATHEMATICS FOR FUTURE MILITARY ENGINEERS

In today's conditions, special attention is paid to ensuring the defense capability of the state, which requires from the system of higher military education the training of a future officer capable of solving military-technical problems of any complexity based on the basic knowledge that he received while studying at a higher military educational institution. As the most regulated sphere of education, military education requires the introduction of innovative technologies that will increase the interest of cadets and the degree of materials assimilation, in particular, in the academic discipline «Higher Mathematics». The problem of choosing teaching technologies in higher military educational institutions can be recognized as one of the most important, requiring theoretical and practical development at the level of teaching of each individual discipline and educational process in general. The purpose of the article is theoretical and empirical substantiation of the modern innovative technologies use in the process of studying higher mathematics in higher military educational institutions. The following methods were used during the research: theoretical ‒ the study and analysis of literature on the introduction of innovative technologies into the educational process of higher educational institutions and higher military educational institutions; modeling; empirical ‒ observation, conversation, testing, methods of statistical analysis for the transformation of empirical data into quantitative indicators. The purpose of our experimental study was to determine the impact of the innovative technologies use on the learning process in higher military educational institutions. The results of the experiment showed the effectiveness of the proposed innovative technologies in the process of fundamental training of future military engineers.

Kernel arquitecture for CAD/CAM in shipbuilding enviroments

The capabilities of complex software products such as CAD/CAM systems are strongly supported by basic information technologies related with data management, visualization, communication, geometry modeling and others related with the development process. These basic information technologies are involved in a continuous evolution process, but over recent years this evolution has been dramatic. The main reason for this has been that new hardware capabilities (including graphic cards) are available at very low cost, but also a contributing factor has been the evolution of the prices of basic software. To take advantage of these new features, the existing CAD/CAM systems must undergo a complete and drastic redesign. This process is complicated but strategic for the future evolution of a system. There are several examples in the market of how a bad decision has lead to a cul-de-sac (both technically and commercially). This paper describes what the authors consider are the basic architectural components of a kernel for a CAD/CAM system oriented to shipbuilding. The proposed solution is a combination of in-house developed frameworks together with commercial products that are accepted as standard components. The proportion of in-house frameworks within this combination of products is a key factor, especially when considering CAD/CAM systems oriented to shipbuilding. General-purpose CAD/CAM systems are mainly oriented to the mechanical CAD market. For this reason several basic products exist devoted to geometry modelling in this context. But these basic products are not well suited to deal with the very specific geometry modelling requirements of a CAD/CAM system oriented to shipbuilding. The complexity of the ship model, the different model requirements through its short and changing life cycle and the many different disciplines involved in the process are reasons for this inadequacy. Apart from these basic frameworks, specific shipbuilding frameworks are also required. This second layer is built over the basic technology components mentioned above. This paper describes in detail the technological frameworks which have been used to develop the latest FORAN version.Postprint (published version

Synthetic in vitro transcriptional oscillators

The construction of synthetic biochemical circuits from simple components illuminates how complex behaviors can arise in chemistry and builds a foundation for future biological technologies. A simplified analog of genetic regulatory networks, in vitro transcriptional circuits, provides a modular platform for the systematic construction of arbitrary circuits and requires only two essential enzymes, bacteriophage T7 RNA polymerase and Escherichia coli ribonuclease H, to produce and degrade RNA signals. In this study, we design and experimentally demonstrate three transcriptional oscillators in vitro. First, a negative feedback oscillator comprising two switches, regulated by excitatory and inhibitory RNA signals, showed up to five complete cycles. To demonstrate modularity and to explore the design space further, a positive-feedback loop was added that modulates and extends the oscillatory regime. Finally, a three-switch ring oscillator was constructed and analyzed. Mathematical modeling guided the design process, identified experimental conditions likely to yield oscillations, and explained the system's robust response to interference by short degradation products. Synthetic transcriptional oscillators could prove valuable for systematic exploration of biochemical circuit design principles and for controlling nanoscale devices and orchestrating processes within artificial cells

Planning For 5G: A Problem Structuring Approach for Survival in the Telecoms Industry

This is the author accepted manuscript. The final version is available from Wiley via the DOI in this recordThis paper examines the application of systemic problem structuring methods to the development of a research strategy in response to the challenges of fifth generation (5G). The paper proposes a methodology for strategic decision making. The key stakeholders, objectives, technologies, and boundaries from existing literature are identified and problem structuring based on hierarchical process modeling is used to explore the dependency of certain features of 5G on specific technologies, giving an indication of the importance of certain technologies over others and thus insight into where to place research effort. The hard technical challenges of 5G are discussed and equally the importance of the soft social and business challenges explored. For context, we explain how 5G will provide a platform for innovations and discuss how new and existing businesses may use this to their advantage. Problem structuring is used to explore how the challenges and opportunities of future wireless systems are related to the process of developing new business models
