Software-Defined NB-IoT Uplink Framework - The Design, Implementation and Use Cases
PublicationIn the radiocommunication area, we may observe a rapid growth of new technology, such as 5G. Moreover, all the newly introduced radio interfaces, e.g., narrowband Internet of Things (NB-IoT), are strongly dependent on the software. Hence, the radiocommunication software development and optimization, as well as the 3GPP technical specification, should be introduced at the academic level of education. In this paper, a software-defined...

Modeling an Industrial Revolution: How to Manage Large-Scale, Complex IoT Ecosystems?
PublicationAdvancements around the modern digital industry gave birth to a number of closely interrelated concepts: in the age of the Internet of Things (IoT), System of Systems (SoS), Cyber-Physical Systems (CPS), Digital Twins and the fourth industrial revolution, everything revolves around the issue of designing well-understood, sound and secure complex systems while providing maximum flexibility, autonomy and dynamics. The aim of the...

An observability and detectability analysis for non-linear uncertain CSTR model of biochemical processes
PublicationThe problem of proving observability/detectability properties for selected non-linear uncertain model of biochemical processes has been addressed in this paper. In particular, the analysis of observability/detectability in the face of parametric and unstructured uncertainty in system dynamics transformed into unknown inputs, and unknown initial conditions has been performed. Various sets of system measured outputs were taken into...

Modelling of size effects in concrete using elasto-plascity with non-local softening
PublicationArtykuł przedstawia numeryczne symulacje MES efektów skali w materiałach kruchych takich jak beton , wykonane w warunkach płaskiego stanu odkształceń. Materiał był modelowany w ramach sprężysto-plastyczności z izotropowym wzmocnieniem i osłabieniem. W obszarze ściskania przyjęto liniowe kryterium Druckera-Pragera z niestowarzyszonym prawem płynięcia a w obszarze rozciągania liniowe kryterium Rankina ze stowarzyszonym prawem płynięcia....

A non local hypoplastic constitutive law to describe shear localization in granular bodies.
PublicationPrzedstawiono wyniki numerycznej analizy formacji stref ścinania w materiale granulowanym podczas ściskania. Zachowanie suchego piasku podczas testów ściskania w płaskim stanie odkształcenia było analizowane z zastosowaniem metody elementów skończonych i nielokalnego hipoplastycznego prawa konstytutywnego. Podczas obliczeń numerycznych zwrócono szczególną uwagę na wpływ długości charakterystycznej na nośność i szerokość...

Communication: Inside the water wheel: Intrinsic differences between hydrated tetraphenylphosphonium and tetraphenylborate ions
PublicationTetraphenylphosphonium tetraphenylborate (TPTB) is a common reference electrolyte in physical chemistry of solutions allowing for a convenient partitioning of thermodynamic properties into single-ion contributions. Here, we compute on the basis of ab initio molecular dynamics simulations the infrared (IR) spectra for hydrated constituent ions of the TPTB assumption. Using spectral decomposition techniques, we extract important...

Distributed protection against non-cooperative node behavior in multi-hop wireless networks
PublicationAn important security problem in today's distributed data networks is the prevention of non-cooperative behavior i.e., attacks consisting in the modification of standard node operation to gain unfair advantage over other system nodes. Such a behavior is currently feasible in many types of computer networks whose communication protocols are designed to maximize the network performance assuming full node cooperation. Moreover, it...
