Several studies on photovoltaic systems focused on how it operates and energy required in operating it. Little attention is paid on its configurations, modeling of mean time to system failure, availability, cost benefit and comparisons of parallel and series–parallel designs. In this research work, four system configurations were studied. Configuration I consists of two sub-components arranged ...

To quantify the interaction between epinephrine infusion and carotid sinus baroreceptor reflex control of vascular capacity and resistance, we have simultaneously measured total systemic compliance, Ct, arterial compliance, Ca, changes in "unstressed vascular volume," AV0, and resistance, R, in nine dogs whose carotid sinuses were isolated and cardiac output fixed by a perfusion pump. In respon...

in this paper, the validity of the key prediction of adaptive dispersion theory was tested. according to this prediction, vowels of a given language are organized in such a way that they are sufficiently distinct on the perceptual level. it implies that more crowded inventories, which also have wider f1 dimension, occupy greater vowel spaces than inventories with fewer vowels.  to investigate t...

research on stress and stress perception has primarily focused on the acoustic characteristics of stressed versus unstressed syllables, and how listeners make use of acoustic cues to make judgements as regards the occurrence of stress. Most phoneticians agree that the three acoustic dimensions involved in the realisation of stress are duration, fundamental frequency, and intensity. These acoust...

Four cases of apparently voluntary rapid vibratory pacifier movements occurring in normal, unstressed infants up to 1 year of age and captured on video are presented. I speculate on the possible relationship of the movements to similar vibratory jaw movements in dogs, in which species they may represent a neuromuscular mechanism for rapid feedback control.

The alterations in regional diastolic mechanics that occur during regional myocardial ischemia (creep and increased myocardial stiffness) may be the result of interactions between the ischemic and surrounding nonischemic myocardium rather than the direct result of ischemia. Thus similar changes may not occur when the entire left ventricle is ischemic. To investigate this proposition, left ventr...
