Infants’ visual preference for infant-directed (ID) faces over adult-directed (AD) faces was examined in two experiments that introduced controls for emotion. Infants’ eye movements were recorded as they viewed a series of side-by-side dynamic faces. When emotion was held constant, 6-month-old infants showed no preference for ID faces over AD faces, but a second group of infants looked signific...

A recent publication [l] introduced the concept of current conveying and an implementation in the form of a circuit building block termed the current conveyor (CC). This block has proven to be useful in many inst.rumentation applications, some of which have already been test)ed and reported [2], [3], while others are still under investigation. This correspondence introduces another new building...

The successful teaching of the object oriented programming paradigm has been identified as a difficult task. Coupled with the difficulty of conveying abstract concepts in general to students, is the complexity of the object oriented paradigm itself. A common approach to conveying complex abstract notions (such as algorithms or data structures) is the use of visualisations. This paper describes ...

Vibratory feeders are commonly used in industries for part feeding. There are several factors that affect the conveying velocity of parts on the vibratory feeder. Among these, the critical factors such as excitation frequency, amplitude of vibration, mass of part, co-efficient of friction and Length-towidth (L/W) ratio of the part were considered for experimental studies. The percentage of infl...

The main cue to interrogativity in Dutch declarative questions is found in the final boundary tone. When whispering, a speaker does not produce the most important acoustic information conveying this: the fundamental frequency. In this paper listeners are shown to perceive the difference between whispered declarative questions and statements, though less clearly than in phonated speech. Moreover...
