Elastyczne formy zatrudnienia osób bezrobotnych powyżej 50. roku życia
PublicationJednym z podstawowych problemów polskiego rynku pracy jest powszechne zastępowanie przez pracodawców umów o pracę, zatrudnieniem cywilnoprawnym bądź nadużywanie zatrudnienia pracowników na podstawie umów o pracę na czas określony. Jednocześnie w Polsce w dynamicznym tempie rozwija się szara strefa oraz jej udział w oficjalnym PKB. W związku z powyższym rygoryzm ustawowy, z jednej strony oraz praktyka życia gospodarczego, z drugiej...

Typologia aktywności online konsumenta w zakresie marki
PublicationWeb 2.0 daje konsumentom nieograniczone możliwości wchodzenia w interakcje, wypowiadania się, udostępniania oraz kreowania treści dotyczących produktów i marek. Tego typu aktywność konsumentów, która ma miejsce w Internecie (tzw. COBRA), stanowi wielką wartość dla firm. Niniejszy artykuł stanowi pierwszą próbę przedstawienia pełnej klasyfikacji tego typu zachowań w trzech głównych kategoriach (konsumpcji, kontrybucji i kreacji),...

Comprehensive analysis of low-temperature methods for reclaiming of ground tire rubber
PublicationManagement of waste tires has become an important topic for decades. The lack of an effective method to manage the materials as mentioned above leads to illegal landfills. This problematic waste can be divided into two main categories depending on the physical condition of the waste: (i) partially used tires; (ii) end-of-life tires. While the first group can be reused or retreaded, the second group requires special measures to...

Modelowanie rozwoju regionalnej sieci połączeń kolejowych z wykorzystaniem metody analitycznego procesu sieciowego
PublicationW artykule przedstawiono wielokryterialny model decyzyjny dla kategoryzacji linii kolejowych w województwie pomorskim z uwagi wymogi użyteczności publicznej. Punktem odniesienia dla analizy był Plan zrównoważonego rozwoju publicznego transportu zbiorowego w województwie pomorskim, w którym z uwagi na niezbędną elastyczność decyzyjną nie dokonano parametryzacji kryteriów decydujących o przypisaniu linii do segmentu użyteczności...

Modelowanie matematyczne systemów fizjologicznych i farmakokinetycznych dla wspomagania diagnostyki terapii
PublicationKsiążka 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...

Electrochemical degradation of textile dyes in a flow reactor: effect of operating conditions and dyes chemical structure
PublicationIn 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....

Speed sensorless ac drive with inverter output filter and fault detection using load torque signal
PublicationIn 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...
