This study quantified the separate contributions of the intensity of exercise and its duration to muscular effort and dyspnoea during cycle ergometry. Six normal subjects estimated the perceived intensity (Borg scale 0-10) of peripheral muscular effort and dyspnoea during incremental exercise to their maximum work capacity (Wcap). On separate days, the same subjects exercised to endurance or 60...

Network growth can be framed as a competition for edges among nodes in the network. As with various other social and physical systems, skill (fitness) and luck (random chance) act as fundamental forces driving competition dynamics. In the context of networks, cumulative advantage (CA) – the rich-get-richer effect – is seen as a driving principle governing the edge accumulation process. However,...

By examining acoustic marks of Czech stress, this paper attempts to provide an answer to the question of whether or not perceived accents in the Czech language have an objective existence. A neural network is used to predict the position of accents without lexical information. Three parameters (intonation, duration and intensity) are considered individually, in pairs and altogether. Fundamental...

Our research group has postulated a perceptually based multiphrase prosody framework for speech paragraphs in fluent speech using corporal analyses. The framework features a prosody hierarchy that organizes phrases and sentences into prosodic groups (PG) in connected speech, and specifies cross-phrase prosodic relationships in the acoustic domains [1, 2]. A corresponding fluent speech prosody m...

PURPOSE To examine the effects of intensity and duration of exercise stress on induction of in vivo immunity in humans using experimental contact hypersensitivity (CHS) with the novel antigen diphenylcyclopropenone (DPCP). METHODS Sixty-four healthy males completed either 30 min running at 60% V˙O2peak (30MI), 30 min running at 80% V˙O2peak (30HI), 120 min running at 60% V˙O2peak (120MI), or ...

The inclusion of emotional aspects into speech can improve the naturalness of speech synthesis system. The different emotions sadness, angry, happiness are manifested in speech as prosodic elements like time duration, pitch and intensity. The prosodic values corresponding to different emotions are analyzed at word as well as phonemic level, using speech analysis and manipulation tool PRAAT. Thi...

The intensity of experimental pain is known to be dependent on stimulation duration. However, it remains unknown whether this effect arises largely from the actual stimulus duration or is substantially influenced by the subject's perception of the stimulus duration. In the present study, we questioned this issue by misleading the perception of the duration of pain in a population of 36 healthy ...
