This paper presents a comparative analysis of two resource reservation protocols, ST-II 6] and RSVP 7], in support of an Integrated Services Packet Network (ISPN). We use simulations to examine the network-wide resource requirements for each protocol to support a number of application communication styles, across a range of group sizes and membership distributions. We also present a comparison ...

Recent developments in man–machine interaction have motivated researchers to recognize human emotion from speech signals. In this study, we propose using nonlinear dynamics features (NLDs) for emotion recognition. NLDs are extracted from the geometrical properties of the reconstructed phase space of speech signals. The traditional prosodic and spectral features are also used as a benchmark. The...

We test whether the complexity of the cardiac interbeat interval time series is simply a consequence of the wide range of scales characterizing human behavior, especially physical activity, by analyzing data taken from healthy adult subjects under three conditions with controls: (i) a "constant routine" protocol where physical activity and postural changes are kept to a minimum, (ii) sympatheti...

Distributed cortical solutions of magnetoencephalography (MEG) and electroencephalography (EEG) exhibit complex spatial and temporal dynamics. The extraction of patterns of interest and dynamic features from these cortical signals has so far relied on the expertise of investigators. There is a definite need in both clinical and neuroscience research for a method that will extract critical featu...

This descriptive study looked into Persian learners’ autonomy and its ties with in-class group dynamics. The participants were undergraduate learners and M.A. students together with their teachers. Data were collected, using a questionnaire, on the participants’ beliefs about autonomy, their autonomous behaviors, and their perceptions of group norms and group cohesiveness. Corresponding teacher...

Group-work dynamics has been assumed to explain a great part of impact in language learningand teaching in specific contexts or for particular skills. In the same vein, structural accuracy hasbeen significant in foreign language learning. Today, foreign language learning is not limited tothe classroom environment. In addition, it encompasses the learner’s lives, so that selfregulation’srole see...

many real time processes have complex, uncertain and nonlinear dynamics. boilers are nonlinear, time varying, multi-input multi-output (mimo) systems, whose states generally vary with operating conditions. the major problem in controlling that system is that its drum water pressure and steam flow dynamics include an integrator that results a critically stable behavior. conventional controller p...

12 Abstract The authors work as online tutors for a BSc (Hons) physiotherapy programme at 13 Coventry University in the United Kingdom. This paper represents a stage in our 14 developing understanding, over a 3 year period, of the impact of group dynamics on online 15 interaction among physiotherapy students engaged in sharing with their peers their first 16 experiences of clinical practice. Th...
