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.

In our paper we discuss the implementation and the presentation features of our three-dimensional virtual library model based on the structure of the classification system of the ancient Library of Alexandria devised by the famous poet, Callimachus in the 3rd century BC. In the first version of the model we used English translations of biographies and selected literary works, but we have already started to upload Hungarian translations of some items in the database. Currently we are enhancing the content of the database with additional items of different verbal and/or multimedia text types. There are two specific aims which we would like to achieve using the 3DVLM. First, we would like to help our users be acknowledged with the literary works of the ancient Alexandrian times and, to understand and interpret the texts, acquire basic knowledge of the related mythological content. Second, in the course of reading, understanding and memorizing the various materials provided by the knowledge base of the 3DVLM, the users are inspired to gradually develop their linguistic (and also generic) knowledge, which, in our case, related to English language. In our paper we implemented a hierarchical model which has been elaborated specifically for describing different aspects of efficiency in multimedia language learning supporting systems. We focus on the effectiveness of this model and elaborate some intrinsic details of its data structure emphasizing the role of knowledge organization in the learning material. The most significant cognitive aspects of our 3DVLM are highlighted as well.

The Sprego (Spreadsheet Lego) programming method facilitates the use of different educational tools and environments to provide better understanding of spreadsheet programming while developing computational thinking and algorithmic skills. With virtual reality technologies gaining attention and popularity, our goal was to investigate and create a virtual workspace in which the students can find all the information and resources they need while learning spreadsheet programming, computer problem solving, and understanding, building algorithms. Following on this principle, we developed a 3D virtual collaboration space to provide students with one interface featuring the information and resources required to practice the Sprego method outside of and during classes. We have collected, refined, and structured the available sources and developed detailed tasks with explanations for students in the form of online documents. Our goal was to provide an all-in-one environment for the Sprego method to learn, explore, and practice all its aspects without leaving the 3D space. For our work, we examined different applications that provide virtual 3D spaces with educational support in mind. Our choice was the MaxWhere Seminar system, based on its innovative and effective approach in the field.

Purpose of this study is to create articulation features for visual speech synthesis. Phonetic alphabet of Shaanxi Xi'an dialect has been created based on the Chinese Pinyin Scheme, which is the official Romanization system for Mandarin. It shares the common phonemes with Mandarin and supplements some special phonemes and Tone-Contour patterns. Firstly, this paper illustrates the corresponding relationship of phonemes comparing this dialect with Mandarin. Then a series of SAMPA code for Shaanxi Xi'an dialect has been developed. A detailed description of the Tone-Contour patterns of Shaanxi Xi'an dialect is given and contrasted with that of Mandarin. The correspondent regularities on consonants, vowels in the whole syllable pronunciation are also expressed between Mandarin and Shaanxi Xi'an dialect.
