Time-varying ISS-Lyapunov functions for impulsive systems provide a necessary and sufficient condition ISS. This property makes them more powerful tool stability analysis than classical candidate providing only ISS condition. Moreover, time-varying cover with simultaneous instability in continuous discrete dynamics which remain inconclusive. The present paper links these two concepts by suggest...

In this paper we present a role based approach to the analysis of computer-based information systems (ISs). The concept of work role is a good tool for representing work and division of labour, and the computer supported tasks make no exception of this. Relationships between actors, roles, tasks and computer systems are discussed from the act-oriented perspective. Role based analysis of an acti...

Since the issue of the first regulations concerning the remediation of contaminated sites, the Istituto Superiore di Sanità, on the basis of specific requests, has drawn up various technical opinions regarding the proposed reference values (quality standards) for soils and underground waters, to be achieved when remediating contaminated sites, for substances for which no standard limit values d...

BACKGROUND The International Space Station (ISS) represents a unique biotope for the human crew but also for introduced microorganisms. Microbes experience selective pressures such as microgravity, desiccation, poor nutrient-availability due to cleaning, and an increased radiation level. We hypothesized that the microbial community inside the ISS is modified by adapting to these stresses. For t...

The Mt. Rudnaya MSS-ISS (monosulfide and intermediate solid solution) fine-grained ores from a NE termination of Norilsk 1 deposit were analyzed using combination X-ray computed micro tomography, spectral tomography scanning electron microscopy to achieve both, 2D 3D data. consist ISS composed tiny lamellar intergrowths cubanite chalcopyrite solutions, which form up 4-mm distinct globules surro...

This paper aims to discuss and analyze the potentialities of Recurrent Neural Networks (RNN) in control design applications. The main families RNN are considered, namely Nonlinear AutoRegressive eXogenous, (NNARX), Echo State (ESN), Long Short Term Memory (LSTM), Gated Units (GRU). goal is twofold. Firstly, survey recent results concerning training that enjoy Input-to-State Stability (ISS) Incr...

BACKGROUND The built environment of the International Space Station (ISS) is a highly specialized space in terms of both physical characteristics and habitation requirements. It is unique with respect to conditions of microgravity, exposure to space radiation, and increased carbon dioxide concentrations. Additionally, astronauts inhabit a large proportion of this environment. The microbial comp...

This paper presents the results of application of innovative knowledge-based multi-agent technology for scheduling of flight program, cargo flow, fuel, water, and other resources of International Space Station (ISS). The developed system aims creating solid information space for scientists, responsible for ISS life activity and supply with various resources and provides intelligent scheduling c...

The input-to-state stability (ISS) problem is studied for switched systems with infinite subsystems. By the method of multiple Lyapunov function, a sufficient ISS condition is given based on a quantitative relation of the input and the values of the Lyapunov functions of the subsystems before and after the switching instants. In terms of the average dwell-time of the switching laws, some suffic...
