Effect of surface roughness on thermal-hydraulic characteristics of plate heat exchanger
PublicationIn the paper the experimental analysis of passive heat transfer intensification in the case of modeled plate heat exchanger is conducted. The plate heat exchanger is chosen for the analysis because this kind of heat exchangers could be prospectively applied in the ORC systems, however other areas or application are equally possible. The experimental setup was assembled at the Department of Energy and Industrial Apparatus of Gdansk...

The effect of the late wood share in the annual ring growth on the cutting power
PublicationW pracy przedstawiono wpływ udziału drewna późnego w przyroście rocznym na zapotrzebowanie mocy skrawania na jedną piłę podczas przecinania drewna sosnowego na pilarce ramowej PRW15-M. Drewno sosnowe pochodziło z 4. Krain Geograficznych Polski. Otrzymane wyniki poddano analizie statystycznej, która wykazała, że dla większości Krain korelacja pomiędzy udziałem drewna późnego w przyroście rocznym i mocą skrawania była znacząca na...

Subsoil degradation effect in reliability analysis of the jack-up platform structure
PublicationStructural reliability analysis is considered, by FORM and SORM applied to a certain idealized soil-platform structure interaction problem due to cyclic water wave and wind loads. Wave and wind loads are random variables, whereas dead load is deterministic. Load parameters are typical for storm conditions in the Baltic Sea. The soil-structure interaction is idealized as a set of linear translational and rotational springs. Due...

The effect of earth fault current harmonics on tripping of residual current devices
PublicationSzerokie zastosowanie przekształtników, a w szczególności przemienników częstotliwości sprawia, że wyłączniki różnicowoprądowe znajdują się w obwodach, w których może płynąć odkształcony prąd ziemnozwarciowy. Prąd ziemnozwarciowy w obwodach z przemiennikami częstotliwości zawiera harmoniczne, których rząd głównie zależy od częstotliwości PWM. Odkształcony prąd wpływa na poprawne wyzwalanie wyłączników różnicowoprądowych. W artykule...

Gain deficit effect in the fractional delay filter design by the window method
PublicationMetoda okien jest sposobem szybkiego i skutecznego projektowania filtrów ułamkowoopóźniających. Jednakże wzmocnienie tak zaprojektowanego filtru różni się od zakładanej wartości idealnej. To zjawisko, nazywane deficytem wzmocnienia, negatywnie wpływa na jakoś projektowanego filtru. Artykuł poświęcono wynikom badań oraz metodom korekcji tego problemu. Omówiono wpływ współczynnika korekcji deficytu wzmocnienia na charakterystykę...

The Effect Fabrication Method of Cobalt Base Clad Layer On Air Oxidation
PublicationNapawane warstwy ze stopu kobaltu zostały wykonane za pomocą napawania plazmowego (PTA) oraz laserowego. Zostały one poddane utlenia niu w temperarurze 1100 stopni celsiusza prze 200 godzin. Przeprowadzono badania mikrostruktury i składu chemicznego warstwy tlenkowej oraz głębszych warstw napoiny. Nie stwierdzono wpływu metody wytwarzania na skutki procesu utleniania.

Effect of welding conditions on susceptibility to cold cracking of underwater welded joints
PublicationPrzedstawiono wybrane aspekty spawalności stali przy spawaniu pod wodą metodą lokalnej komory suchej. Zwrócono szczególną uwagę na skłonność do tworzenia peknięć zimnych w SWC. Przy pomocy planowania doświadczeń określono ilościowy wpływ parametrów spawania na naprężenia krytyczne z próby implant.

Charge photogeneration effect on the exciplex emission from thin organic films
PublicationZaobserwowano silne wygaszenie fluorescencji i fosforescencji ekscypleksowej w układzie dwuamina TPD (donor elektronu): pochodna fenantroliny BPT (akceptor elektronu) w zewnętrznym polu elektrycznym. Efekt ten przypisano wygaszaniu molekularnych ekscytonów singletowych TPD na elektronach akceptorów BPT.

The effect of improved cutting conditions of the circular saw blade on precision of cutting
PublicationW pracy przedstawiono analizę i wyniki badań doświadczalnych dokładności przecinania na dwuwrzecionowej pilarce tarczowej. W warunkach przemysłowych badano piły starej (typ "Multix") i nowej konstrukcji podczas przecinania pryzm ze zmrożonego drewna brzozowego. Ponadto, określono wpływ kinematyki układu przecinania na uzyskiwaną dokładność przecinania.

Ultrashort Opposite Directed Pulses Dynamics with Kerr Effect and Polarization Account
PublicationWe present the application of projection operator methods to solving the problem of the propagation and interaction of short optical pulses of different polarizations and directions in a nonlinear dispersive medium. We restrict ourselves by the caseof one-dimensional theory, taking into account material dispersion and Kerr nonlinearity. The construction of operators is delivered in two variants: for the Cauchy problem and for the...

Effect of starch fillers on the dynamic mechanical properties of rubber biocomposite materials
PublicationIn the paper the results of dynamic mechanical study of the biocomposites containing one of two types of (potato or corn) strach used as fillers in different amount were discussed. The composites were obtained from rubbery mixture containing natural rubber (NR) as a main component. Thermomechanical analyses (by DMA) showed that the used quantity of strach fillers only slightly influence on the glass transition temperature of vulcanizates.

Dead-Time Effect Compensation Based on Additional Phase Current Measurements
PublicationThis paper proposes a new method of dead-time effect compensation. The proposed solution is based on additional phase current measurements realized by analog-to-digital converters. These measurements are carried out at the time instants specified by a pulsewidth-modulation (PWM) strategy. This makes it possible to estimate inverter currents at the commutation instants and, finally, to estimate the voltage error caused by dead time. This...

The effect of circular saw blade clamping diameter on its resonant frequencies
PublicationIn this paper results of comparison of characteristic resonant frequencies of circular saw blades as a function of saw clamping diameter from the impact test are presented. Obtained results revealed that proportionally with the increase of the saw clamping diameter also the dynamical stiffness of the saw blade increased. As a consequence of that the resonant frequencies of the saw blade move to higher values. Moreover, with the...
