چکیده
This paper reports results from a comparative analysis of purring in four domestic cats. An acoustic analysis describes sound pressure level, duration, number of cycles and fundamental frequency for egressive and ingressive phases. Significant individual differences are found between the four cats in several respects.

متن کاملA comparative acoustic analysis of purring in juvenile, subadult and adult cheetahs
Previous studies of cheetah purring have described purring in adult cheetahs. This paper extends the cheetah purring research to include juvenile and subadult cheetahs and analyzes purring data from cheetahs in ages ranging from 7 months to 7 years, and with weights ranging from 18 kilos to over 70 kilos. Results show that while there is considerable variation across most parameters analysed (a...

متن کاملCluster Analysis of Acoustic Emission Signals for Carbon/Epoxy Composite in Four-point Bending Test (RESEARCH NOTE)
Due to the extensive use of composites in various industries and the fact that defects reduce ultimate strength and efficiency during operation, detection of failures in composite parts is very important. The aim of this paper is to use Acoustic Emission (AE) non-destructive method in four-point bending test of carbon/epoxy composite to analyze and examine the failure mechanisms. This method is...
متن کاملAnalysis of feral cats role in dissemination of Toxoplasma gondii infection in rural area, Golestan province, North-East of Iran
Background and aims: Cats carry a lot of zoonotic parasites such as Toxoplasma gondii (T. gondii) which causes toxoplasmosis in warm-blooded animals. Toxoplasmosis includes wide range of symptoms in its intermediate and definitive hosts but the worst symptoms have been seen in pregnant women and also on immunocompromised hosts. Considering the importance of the fact that cats are as the only de...
