Speed sensorless ac drive with inverter output filter and fault detection using load torque signal
PublikacjaIn this paper, a sensorless induction motor (IM) drive using speed observer system is presented. The system includes load torque computation for gear fault detection. Nonlinear control method is adopted for controlling the motor over a wide speed range. An LC filter for smoothing current and voltage waveforms is used at the output of the voltage inverter. The use of filter imposes more building of the used observer to avoid using...

Interictal high-frequency oscillations in focal human epilepsy
PublikacjaPURPOSE OF REVIEW: Localization of focal epileptic brain is critical for successful epilepsy surgery and focal brain stimulation. Despite significant progress, roughly half of all patients undergoing focal surgical resection, and most patients receiving focal electrical stimulation, are not seizure free. There is intense interest in high-frequency oscillations (HFOs) recorded with intracranial electroencephalography as potential...

Pathological brain network activity: memory impairment in epilepsy
PublikacjaOur thinking, memory and cognition in general, relies upon precisely timed interactions among neurons forming brain networks that support cognitive processes. The surgical evaluation of drug-resistant epilepsy using intracranial electrodes provides a unique opportunity to record directly from human brain and to investigate the coordinated activity of cognitive networks. In this issue of Neurology®, Kleen and colleagues1 implicate...

Electrochemical degradation of textile dyes in a flow reactor: effect of operating conditions and dyes chemical structure
PublikacjaIn this study, electrochemical oxidation of five azo dyestuffs (Yellow D-5GN, Red D-B8, Ruby F-2B, Blue D-5RN, Black DN), that are widely used in the textile industry, was investigated in a flow reactor. BDD electrode with a high boron doping level (C/B = 10 000) was prepared and used. Two configurations of reactor were considered, i.e., one with the undivided cell, and the other with the cell divided by anodic and cathodic compartments....

Impact of influent wastewater quality on nitrogen removal rates in multistage treatment wetlands
PublikacjaNitrogen removal in treatment wetlands is influenced by many factors, and the presence of electron donors (biodegradable organic matter) and electron acceptors (nitrate ions) is the main limiting one; for obtaining these conditions, multistage treatment wetlands (MTWs) are required, where an extensive nitrification can be obtained in the first stages under aerobic conditions leaving then to the following anoxic/anaerobic stages...

Quantum metrology: Heisenberg limit with bound entanglement
PublikacjaQuantum entanglement may provide a huge boost in the precision of parameter estimation. However, quantum metrology seems to be extremely sensitive to noise in the probe state. There is an important still open question: What type of entanglement is useful as a resource in quantum metrology? Here we raise this question in relation to entanglement distillation. We provide a counterintuitive example of a family of bound entangled states...

Poly(ferrocenylsilane-block-methacrylates) via sequential anionic and atom transfer radical polymerization.
PublikacjaArtykuł przedstawia sposób otrzymywania kopolimerów blokowych poli(ferrocenylosilanów) (PFS) i poli(metakrylanu metylu) (PMMA). W pierwszej kolejności syntezowany jest anionowo blok PFS, który po odpowiedniej terminacji służy jako makroinicjator dla syntezy bloku PMMA. Synteza ta jest realizowana przy użyciu polimeryzacji rodnikowej z przeniesieniem atomu (ATRP), katalizowanej przez kompleksy rutenu. Otrzymane w ten sposób kopolimery...

Długookresowe wahania przepływów rocznych głównych rzek w Polsce i ich związek z cyrkulacją termohalinową Atlantyku Północnego
PublikacjaPraca dotyczy przyczyn występowania multidekadowej zmienności średnich rocznych przepływów największych rzek Polski (Wisła, Bug, Odra, Warta). Taka zmienność powoduje, że w wieloletnich przebiegach przepływów rocznych zaznaczają się zmiany znaków trendów (z dodatnich na ujemne i odwrotnie). Przyczyną jest długookresowa zmienność składowej powierzchniowej cyrkulacji termohalinowej na północnym Atlantyku (NA THC – Northern Atlantic...

Entanglement and Nonlocality are Inequivalent for Any Number of Parties
PublikacjaUnderstanding the relation between nonlocality and entanglement is one of the fundamental problems in quantum physics. In the bipartite case, it is known that these two phenomena are inequivalent, as there exist entangled states of two parties that do not violate any Bell inequality. However, except for a single example of an entangled three-qubit state that has a local model, almost nothing is known about such a relation in multipartite...

Modelowanie matematyczne systemów fizjologicznych i farmakokinetycznych dla wspomagania diagnostyki terapii
PublikacjaKsiążka jest poświęcona matematycznemu modelowaniu systemów biomedycznych, ze szczególnym uwzględnieniem systemów fizjologicznych i farmakokinetycznych. W tym obszarze bardzo przydatne są metody modelowania kompartmentowego, wykorzystujące opis systemu w kategoriach zmiennych stanu. W tych kategoriach sformułowana jest także teoria filtracji stochastycznej Kalmana. Filtracja stochastyczna stosowana jest do usuwania zakłóceń z sygnału...

Climate change impact on groundwater resources in sandbar aquifers in southern Baltic coast
PublikacjaShallow coastal aquifers are vulnerable hydrosystems controlled by many factors, related to climate, seawater‑freshwater interactions and human activity. Given on‑going climate change, sea level rise and increasing human impact, it is especially true for groundwater resources situated in sandbars. We developed numerical models of unsaturated zone water flow for two sandbars in northern Poland: the Vistula Spit and the Hel Spit...

Performance tuning of chitosan-based membranes by protonated 2-Pyrrolidone-5-carboxylic acid-sulfolane DES for effective water/ethanol separation by pervaporation
PublikacjaToday, the applicability of deep eutectic solvents (DES) in various fields, including membrane science and technology, is extensively investigated. In pioneering works, we have implemented different DES as a component of chitosan (CS)-based flat membranes for pervaporation (PV) separation. Herein, we present a new protonated (by sulphuric acid) 2-Pyrrolidone-5-carboxylic acid: sulfolane DES, as a green additive for its chemical...
