This investigation examined the degree to which modification of the consonant-vowel (C-V) intensity ratio affected consonant recognition under conditions in which listeners were forced to rely more heavily on waveform envelope cues than on spectral cues. The stimuli were 22 vowel-consonant-vowel utterances, which had been mixed at six different signal-to-noise ratios with white noise that had been modulated by the speech waveform envelope. The resulting waveforms preserved the gross speech envelope shape, but spectral cues were limited by the white-noise masking. In a second stimulus set, the consonant portion of each utterance was amplified by 10 dB. Sixteen subjects with normal hearing listened to the unmodified stimuli, and 16 listened to the amplified-consonant stimuli. Recognition performance was reduced in the amplified-consonant condition for some consonants, presumably because waveform envelope cues had been distorted. However, for other consonants, especially the voiced stops, consonant amplification improved recognition. Patterns of errors were altered for several consonant groups, including some that showed only small changes in recognition scores. The results indicate that when spectral cues are compromised, nonlinear amplification can alter waveform envelope cues for consonant recognition.

In the age of digital transformation of production processes in industry and science the development and design of intelligent flow sensors for granular and liquid substances transferring through pipelines becomes more important. With this in view new approaches for improving the accuracy of microwave flowmeters are proposed. Taking into account the characteristics ofelectromagnetic waves propagating through a pipeline, a wave scattered by inhomogeneities of the controlled medium is analyzed. Features of the transformation of the polarized scattered wave limiting the geometric dimensions of the pipeline and optimizing the values of the useful scattered signal are revealed. Expediency of collection of the information signal with orthogonal polarization of the scattered wave and through a directional coupler is substantiated. The method of estimating the measurement accuracy with reference to the signal-to-noise ratio at the input of the processing device is given. The research results can be used in cryogenic machine engineering to measure volume and mass flows of liquid cryogenic products.

Tujuan dari penelitian ini untuk mengetahui pengaruh ukuran perusahaan (size),leverage, capital intensity ratio, dan kepemilikan manajerial terhadap agresivitas pajak.Penelitian ini menggunakan sampel perusahaan perbankan selama tahun 2010-2014dengan menggunakan purposive sampling. Data yang digunakan diperoleh dari laporantahunan perusahaan yang terdaftar di Bursa Efek Indonesia sebanyak 11 perusahaan.Metode analisis yang digunakan adalah analisis regresi berganda, yaitu Uji F statistik,Uji t statisitik dan pengolahan data diolah dengan program SPSS.Hasil penelitian menunjukkan bahwa secara parsial (Ujit t) menunjukkan ukuranperusahaan (size) dan kepemilikan manajerial berpengaruh signifikan terhadapagresivitas pajak sedangkan leverage dan capital intensity ratio tidak berpengaruhsignifikan terhadap agresivitas pajak. Sedangkan secara simultan (Uji F) ukuranperusahaan (size), kepemilikan manajerial leverage dan capital intensity ratioberpengaruh signifikan terhadap agresivitas pajak.Kata Kunci: Agresivitas Pajak, Ukuran Perusahaan (SIZE), Leverage, Capital Intensity Ratio, Kepemilikan Manajerial.
