Music on the radio is often interrupted by advertisements or DJ chatter that the listener would prefer not to hear. In this paper, we discuss a straightforward application of perceptually-based audio feature extraction and classification using a support vector machine to automatically differentiate between music and “non-music” audio, so that when non-music is detected the radio might automatic...

The ubiquity of Online Social Networks (OSNs) is creating new sources for healthcare information, particularly in the context of pharmaceutical drugs. We aimed to examine the impact of a given OSN's characteristics on the content of pharmaceutical drug discussions from that OSN. We compared the effect of four distinguishing characteristics from ten different OSNs on the content of their pharmac...

Female song is an ancestral trait in songbirds, yet extant females generally sing less than males. Here, we examine sex differences in the predation cost of singing behaviour. The superb fairy-wren (Malurus cyaneus) is a Southern Hemisphere songbird; males and females provision the brood and produce solo song year-round. Both sexes had higher song rate during the fertile period and lower song r...

Many people share and communicate their private thoughts and opinions via systems like Facebook and Twitter. In this paper, we analyze if also professional interests of a user can be extracted from these activities and be distinguished from private interests. The results indicate that performance largely depends on the size and quality of the Social Web profiles. Methods for reducing noise and ...

The dynamic stability of the milling process is investigated through a single degree of freedom mechanical model. Two alternative analytical methods are introduced, both based on finite dimensional discrete map representations of the governing time periodic delay-differential equation. Stability charts and chatter frequencies are determined for partial immersion upand down-milling, and for full...

We present a comparative power analysis, via Monte Carlo, of various graph invariants used as statistics for testing graph homogeneity versus a “chatter” alternative – the existence of a local region of excessive activity. Our results indicate that statistical inference on random graphs, even in a relatively simple setting, can be decidedly non-trivial. We find that none of the graph invariants...

The dynamics of the cutting process are investigated. Using the increase of cutting depth as a control parameter, two diierent cutting regimes are observed. In the rst regime, which is observed at small cutting depths, complex, high-dimensional dynamics occur. In the second cutting regime, observed for deeper cuts, low dimensional dynamics are typical. The second cutting regime is usually ident...

Research examining the predictive power of social media (especially Twitter) displays conflicting results, particularly in the domain of political elections. This paper applies methods used in studies that have shown a direct correlation between volume/sentiment of Twitter chatter and future electoral results in a new dataset about political elections. We show that these methods display a serie...

A company cannot be separated from consumers and the products it produces. Consumers certainly hope that goods they buy will able to meet their needs desires so product has good guaranteed conditions. Therefore, companies must see maintain quality of produced is accepted by can compete in market. This study intended analyze whether resulting not accordance with specified standards what factors ...
