Artykuł omawia międzykulturową re-konceptualizację znaczenia sloganu ‘I’m lovin’ it’, spopularyzowanego w Polsce przez międzynarodową sieć restauracji, jaka zachodzi między językiem angielskim i polskim z perspektywy Lingwistyki kulturowej oraz Teorii re-konceptualizacji i aproksymacji. Przedstawiona analiza została oparta na propozycjach przekładu zaproponowanych przez 45 rodzimych użytkowników języka polskiego. Uzyskane rezultaty wskazują, że ponieważ sieci semantyczne dla znaczenia czasownika ‘love’ w języku angielskim i znaczenia czasownika ‘kochać’ w języku polskim nie do końca się pokrywają, próby przeniesienia znaczenia tego sloganu na język polski można traktować jednie jako mniej lub bardziej trafne aproksymacje oryginalnego znaczenia według norm, oczekiwań i postaw funkcjonujących w kulturze docelowej.
Experimental Mg-Al-RE type magnesium alloys for high-pressure die-casting are presented. Alloys based on the commercial AM50
magnesium alloy with 1, 3 and 5 mass % of rare earth elements were fabricated in a foundry and cast in cold chamber die-casting
machines. The obtained experimental casts have good quality surfaces and microstructure consisting of an α(Mg)-phase, Al11RE3,
Al10RE2Mn7 intermetallic compound and small amount of α+γ eutectic and Al2RE phases.
In this paper a sample rate conversion algorithm which allows for continuously changing resampling ratio has been presented. The proposed implementation is based on a variable fractional delay filter which is implemented by means of a Farrow structure. Coefficients of this structure are computed on the basis of fractional delay filters which are designed using the offset window method. The proposed approach allows us to freely change the instantaneous resampling ratio during processing. Using such an algorithm we can simulate recording of audio on magnetic tape with nonuniform velocity as well as remove such distortions. We have demonstrated capabilities of the proposed approach based on the example of speech signal processing with a resampling ratio which was computed on the basis of estimated fundamental frequency of voiced speech segments.
The densification behavior of H13 tool steel powder by dual speed laser scanning strategy have been characterized for selective laser melting process, one of powder bed fusion based metal 3d printing. Under limited given laser power, the laser re-melting increases the relative density and hardness of H13 tool steel with closing pores. The single melt-pool analysis shows that the pores are located on top area of melt pool when the scanning speed is over 400 mm/s while the low scanning speed of 200 mm/s generates pores beneath the melt pool in the form of keyhole mode with the high energy input from the laser. With the second laser scanning, the pores on top area of melt pools are efficiently closed with proper dual combination of scan speed. However pores located beneath the melt pools could not be removed by second laser scanning. When each layer of 3d printing are re-melted, the relative density and hardness are improved for most dual combination of scanning. Among the scan speed combination, the 600 mm/s by 400 mm/s leads to the highest relative density, 99.94 % with hardness of 53.5 HRC. This densification characterization with H13 tool steel laser re-melting can be efficiently applied for tool steel component manufacturing via metal 3d printing.
