At every software design stage nowadays, there is an acute need to solve the problem of effective choice libraries, development technologies, data exchange formats, virtual environment systems, characteristics machines. Due spread various kinds devices and popularity Web platforms, lots systems are developed not for universal installation on a device (box version), but specific architecture with subsequent provision web services. Under these conditions, only way estimating efficiency...

This paper concerns the case of development a technology for increasing efficiency access control based on user behavior monitoring built into software system’s interface. It is proposed to use time reactions as individual indicators psychological and psychophysical state. presents results interpretation collected during mass web survey students Russian Federation. The total number users was equal 22,357. To reveal patterns in reactions, both quantitative qualitative approaches were applied....

Web surveys are very popular in the Internet space. widely incorporated for gathering customer opinion about services, sociological and psychological research, as part of knowledge testing systems electronic learning. When conducting web surveys, one issues to consider is respondents’ authenticity throughout entire survey process. We took 20,000 responses an online questionnaire experimental data. The 45 min on average. did not take into account given answers; we only considered response...

We consider the problem of velocity estimation for a control moment gyroscope inverted pendulum. To this end, we model-free differentiator, model-based linear observer and nonlinear differentiator. The proposed designs are implemented in hardware closed-loop system performance stabilization task is compared. Moreover, show that considered cannot be partially linearized via change coordinates, thus not suitable recently reported class observers.

Contemporary digital platforms provide a large number of web services for learning and professional growth. In most cases, educational only control access when connecting to resources platforms. However, similar (internet surveys, online research), which are characterized by interactive interaction with the platform, it is important assess user engagement in process. A fairly body research devoted assessing learner based on automatic, semi-automatic, manual methods. Those methods include...

Many time series forecasting applications use ranges rather than point forecasts. Producing forecasts in the form of Prediction Intervals (PIs) is natural, since intervals are an important component many mathematical models. The LUBE (Lower Upper Bound Estimation) method aimed at finding based on solving optimization problems taking into account interval width and coverage. Using Particle Swarm Training simple neural network, we look for a solution to problem Coverage Width-Based Criterion...

In this paper we give an overview of both hardware and software architectures real time systems used in devices for various purposes — from lab bench contraptions to cars. The goal the is reveal separate classes such as well define preconditions choosing a particular architecture.

Walking robot dynamic stabilization is a growing field of research as such robots are being constructed for various applications in human environment. The systems often highly non-linear with the additional demand rapid change model mass parameters to meet design requirements. article centres round problem mechanical modelling walking and identifying system using genetic algorithm approach. supposed paper based on inverted pendulum paired gyroscopic units limited kinetic momenta, that shapes...

This article addresses the problem of cloud distributed control systems development for mobile robots. The authors emphasize lack a design methodology to guide process in accordance with specific technical and economic requirements robot. On analysis various robots architectures, set nine most significant parameters are identified direct stage by stage. Based on those parameters, is proposed build scalable three-level system application demonstrated example AnyWalker open source robotics...

Современные цифровые платформы предоставляют большое количество веб-сервисов для обучения и профессионального роста. В большинстве случаев образовательные веб-сервисы контролируют только доступ при подключении к ресурсам платформам. Для образовательных иных ресурсов (интернет-опросы, онлайн-исследования), которые характеризуются интерактивным взаимодействием с платформой, важно контролировать вовлеченность пользователя. Характеристикой вовлеченности может служить время задержки на элементах...
