We investigated the relationships among spectral and temporal advertisement-call characteristics and the sizes of the laryngeal and ear components thought to underlie the generation and reception of species-specific vocalizations in male cricket frogs (Acris crepitans). We tested the predictions that the volumes of the structural elements necessary for acoustic communication would be correlated...

Central to any task-based syllabus is the notion of complexity. Proponents of task-based language teaching (TBLT) have argued that tasks be sequenced according to their inherent cognitive complexity, partially because learner performance changes according to the complexity of the task. This exploratory study examines the effect of task complexity on the linguistic complexity of task performance...

GSM call re-establishment service allows a mobile station to resume a call in which the radio link has been temporarily interrupted due to interference or bad signal (which is referred to as an interrupted call). This service increases end user satisfaction and network quality perception. In this paper, we propose analytic models to study the performance for call re-establishment service. Our s...
