with regard to the importance of instantaneous peak discharge estimation for watershed management study, and due to the lack of and unqualified climatic and hydrologic data for estimation and measurement in countries such as iran, researchers were obliged to establish a link between constant parameters (geomorphologic) and variables (hydrologic) to present models with minimum dependence on clim...

conclusions negative pressure inspiration is significantly impaired by an unstable chest wall. restoring mechanical stability of the fractured ribs improves respiratory outcomes similar to baseline values. results a wide variation in the mean inspiratory volumes and peak flows were measured between specimens; however, the effect of a flail chest wall and the subsequent internal fixation of the ...

In several chaotic systems, the value of a peak (relative maximum) of a variable and its time of occurrence can be predicted, with very good approximation, from the value of the previous peak. This property, which is called peak-to-peak dynamics and which basically relies on the low-dimensionality of the chaotic attractor, allows to approximately model the system in a very compact form by a pea...

We show in this paper that the chaotic regimes of many food chain models often enjoy a very peculiar property, known as peak-to-peak dynamics. This means that the maximum (peak) density of the populations of any trophic level can be easily forecasted provided the last two peaks of the same population are known. Moreover, extensive simulation shows that only the last peak is needed if the foreca...

Mass spectrometry data are often corrupted by noise. It is very difficult to simultaneously detect low-abundance peaks and reduce false-positive peak detection caused by noise. In this paper, we propose to improve peak detection using an additional constraint: the consistent appearance of similar true peaks across multiple spectra. We observe that false -positive peaks in general do not repeat ...
