Starter for Voltage Boost Converter to Harvest Thermoelectric Energy for Body-Worn Sensors
PublikacjaThis paper examines the suitability of selected configurations of ultra-low voltage (ULV) oscilla-tors as starters for a voltage boost converter to harvest energy from a thermoelectric generator (TEG). Important properties of particularly promising configurations, suitable for on-chip imple-mentation are compared. On this basis, an improved oscillator with a low startup voltage and a high output voltage swing is proposed. The applicability...

Analysis of the interfacial energy of GaAs-Si hetrostructures
PublikacjaPrzeprowadzono obliczenia numeryczne energii powierzchni heterogranicy GaAs-Si z zastosowaniem półempirycznego modelu czteroparametrycznego Acklanda. Pokazano zależność energii heterogranicy od orientacji podłoża Si. Minima energetyczne otrzymano dla orientacji Si równych (011), (133), (112) i (113) co wskazuje ich zastosowanie do epitaksjalnego wzrostu warstw GaAs.

Energy optimisation in resilient self-stabilizing processes
PublikacjaW pracy rozważa się rozproszony model obliczeń, w którym struktura systemu jest reprezentowana przez graf bezpośrednich połączeń komunikacyjnych. W tym modelu podajemy nowy samostabilizujący algorytm kolorowania grafów oparty na konstrukcji drzewa spinającego. Zgodnie z naszą wiedzą jest to pierwszy algorytm z gwarantowaną wielomianową liczbą ruchów, który dokładnie koloruje grafy dwudzielne.

Water needs of production of biomass for energy in Poland
PublikacjaPrzedstawiono polskie zamierzenia polityczne dotyczące rozwoju produkcji biomasy do celów energetycznych. Produkcja biomasy wymagać będzie zwiększonego zużycia wody przez rośliny. Wprawdzie w Polsce potrzeby wodne roślin energetycznych będą 2-3 krotnie niższe niż w krajach śródziemnomorskich, tym niemniej opady atmosferyczne w Polsce będą niewystarczające i potrzeby wodne wymagać będą nawodnień na poziomie 50% aktualnych opadów...

Hybrid Multi-Criteria Method of Analyzing the Location of Distributed Renewable Energy Sources
PublikacjaThis paper presents the development and the application of a hybrid multi-criteria method, the combination of the Analytic Hierarchy Process (AHP), and numerical taxonomy (NT),to support the decision making on the location of distributed renewable energy sources meetingvarious types of assessment criteria. Finding criteria weights, using the AHP method, eliminates thedisadvantage of NT—which, in current form, is defined by its...

Effect of the let-through energy of overcurrent protective devices on the temperature of conductors during short-circuits
PublikacjaThe scope of the verification of low-voltage systems covers the earth fault loop impedance measurement. This measurement is usually performed with the use of low-value current meters, which force a current many times lower than the one occurring during a real short-circuit. Therefore, the international standard recommends consideration of the increase of resistance of conductors with the increase of temperature, which may occur...
