The present paper deals with a finite-source retrial queueing system to model cognitive radio networks. Two non independent frequency bands servicing two classes of users are considered: Primary Users (PUs) and Secondary Users (SUs). PUs have preemptive priority over SUs at the licensed spectrum while Sus are served at the normal spectrum containing an orbit for the retrial users. The novelty of this work is that we introduce the server with conflict in the retrial part of the cognitive radio network. Therefore, the arriving secondary customers involve into collision with the secondary customers under service in the SUs, and both joins the orbit. We established a simulation program to model the queueing system and to obtain estimation for the basic performance measures. Since individual users mostly interested in their sojourn time in the system we analyze the impact of the service time distribution (s.t.d) on the expectation and variance of sojourn time of the PUs and SUs, respectively. For illustration various sample examples are derived and Figures are generated for better understanding.

The paper deals with the reinterpretation of Wolfgang Pauli's ‘cognitive revolution’ of imagination and hermeneutical explanation cooperating with C.G. Jung. In the identification of the creative unconscious background processes (a concept introduced by Pauli himself) found in the dreams, imaginations and interpretations of Pauli and Jung, the number-archetypes, structures, patterns and meanings seem to be related to the hidden world of the great monarch Constantine Porphyrogenitus and his ‘followers’.

The way dialogue partners collaborate to achieve a joint task is dependent on the way they construct a common ground of knowledge. Diverse conversational mechanisms are involved in developing a common ground, and repetition phenomena appear to be strongly connected to these processes. This article describes the use of an automatic method to detect, within dialogue transcripts, linguistic cues of engagement and synchrony, by observing repetitions at different linguistic levels. We focus on the relationship between repetition patterns and task-based success in interaction with task-based experience and partner familiarity. We conduct our analysis on the data of the HCRC Map Task corpus. Results suggests that, among other patterns, significant amounts of repetitions play a role for unfamiliar participants, with greater success, in particular, at first attempts.

This study looks into the effect of the video channel, that provides realtime visual information of the subject's inter-locutor in computer mediated multi-lingual map task dialogues. The addition of a video channel in long distance audio communication has been commercially available since 1964, pioneered by AT&T's Picturephone. However the complexity of adding an image channel to a task oriented dialogue has not penetrated the user audience enough to change the user expectation from a like-to-like alternative of Face-to-Face communication, to a new different communication style. This study reports the increase in visual cognitive state occurrences when communicating with a video channel and the different perception that this setting provided to the subjects of the ILMT-s2s corpus.

Monitoring cognitive workload has the potential to improve performance and fidelity in human decision making through a real-time monitoring model. Multiple studies have shown a successful binary classification of high and low workload using various methods and often focused on multiple physiological signals. A more detailed detection of cognitive workload is needed for a meaningful and reliable workload monitoring tool. This study focuses on trinary workload classification of parameters extracted from the cardiovascular system. The experiment was validated with the use of a database containing 96 participants performing tasks designed to induce slight variations in cognitive workload. Two distinct supervised learning classifying methods were used and their likelihood score used for the classification schemes of (1) each heartbeat and (2) each task screen. The results show that the support vector classifier outperforms the random forest with the average misclassification rate of 20.44% using the whole screen classification scheme instead of individual heartbeat classification.

Older adults challenged with vision impairments require special care, often served in residential care institutions. This paper presents outcomes of a user study to reveal everyday needs and problems of clients of such institution. The study was organized as semistructured interviews with residential home clients (N = 6) and staff (N = 6). Our findings indicate that most needs can be already addressed by specific care given in residential institutions. However, we identified areas where ICT could be beneficial for better orientation and well-being of clients. We draw results to motivate and frame design directions.

Viable usage of Brain-Computer Interface (BCI) in real-time applications significantly relies on the pre-processing techniques applied on the detected electroencephalography (EEG) signals. In EEG, sensorimotor (SMR)/oscillatory signals, such as mu and beta rhythm based BCIs, can be used to restore motor function by neuro-plasticity applied to re-establish normal brain function. This study is based on the evaluation of the foot motor execution (ME) and motor imagery (MI), in order to design a BCI neurorehabilitation system. Because foot ME and MI reflect the user's physical and imagination state of foot movement respectively, in order to be used as control signals, their appropriate translation is the basic challenge. This paper mainly focuses on the quantification and investigation of mu-beta event-related desynchronization (ERD) and event-related synchronization (ERS), for inter and intra-subject variability, making use of the available design tools in open-source platforms such as the OpenViBE software. Results show that the frequency of the most reactive components for mu was 8.8±0.5 Hz and 21.3±0.4 Hz for beta. Interestingly a contralateral dominance was visible at electrode position C3 during right foot ME/MI tasks. The results have enabled the implementation of a good platform for left-right foot ME/MI discrimination based BCI applications.

The fuzzy cognitive maps may arouse problems in interpretation, collective knowledge acquisition and stability. We thus suggest a method which applies stepwise regression method and fuzzy rule-based reasoning in model construction, and correlations in interpretation. The Finnish dairy farms' profitability is considered as an example. These methods base on historic data. Hence, we may obtain outcomes which are better understood by the users and provides better collective knowledge.
