    The aim of the paper is to present an integrated app that can be used on mobile devices (e.g. tablets) to assist GPs and nurses with little previous experience in ultrasound scanning. The developed webapp is user friendly, helps users to perform simple ultrasound scans using portable ultrasound devices and acts as a triage tool to cut down the number of unnecessary referrals. The app offers guidance, training and test possibilities for self-study and self-assessment including educational videos. An augmented reality app assists the user in taking the right picture which then can be compared to an extensive reference image library. The app has been validated and the findings are discussed in the paper. View full abstract»

    There are special topics in cognitive infocommunications where the processing of continuous speech is necessary. These topics often require the segmentation of speech signal into phoneme sized units. This kind of segmentation is necessary, when the desired behavior depends on speech timing, like rhythm or the place of voiced sounds (emotion or mood detection, language learning, acoustic feature visualization). Segmentation systems based on the acoustic-phonetic knowledge of speech could be realized in a language independent way. In this paper we introduce a language independent solution, based on the segmentation of continuous speech into 9 broad phonetic classes. The classification and segmentation was prepared using Hidden Markov Models. Three databases were used to evaluate the segmentation systems: Hungarian MRBA, German KIEL and English TIMIT databases. 80% average recognition result was obtained. View full abstract»

    We have developed distributed text-to-audiovisual-speech synthesizer (TTAVS) to support interactivity in computer-aided pronunciation training (CAPT) on a mobile platform. The TTAVS serves to generate audiovisual corrective feedback based on detected mispronunciations from the second language learner's speech. Our approach encodes key visemes in SVG format that are compressed by GZIP and transmitted to the client, where the browser can perform real-time morphing to render the visual speech. We have also developed a TTAVS animation player that can play the audio and visual speech synchronously while enabling user controls in play/pause/resume. Evaluation shows that this newly proposed approach, vis-à-vis our original approach that involves generation of an Ogg video on the server-side which is streamed to the client, achieves a significant reduction (66%) in average size of the output files that are transmitted from the server to the client, reduction of (83%) in client waiting times, as well as preserve the quality of the image.

    This paper introduces a new implementation of Shared Segment Protection (SSP) in mesh communication networks, in which a novel Integer Linear Program (ILP) is proposed under a reduced amount of routing information. In particular, the scheme of Distributed Partial Information Management with Sufficient and Aggregated Information (DPIM-SAM) [1] will be adopted for trading the optimality with the reduction on the computation time. We will verify the ILP formulation by comparing its result with the cases of SSP and Path Shared Protection under the complete routing information scenario (SCI) in terms of performance and computation time.

    Sustainable development in terms of both economy and environment has become as one of the most critical driving forces in shaping and reforming the management system of waste of electrical and electronic equipment (WEEE). The achievement of the balance between economic and environmental performances requires comprehensive analysis and appropriate design of reverse logistics network of WEEE management system. This paper presents a network design model for treating multi-sourced WEEE in a sustainable manner. Economic efficiency and environmental influence in terms of greenhouse gas emission associated with the transportation of WEEE are defined as two main criteria to determine the network configuration. A conceptual model and a mathematical model are designed to illustrate the systematic formation of the reverse logistics network of WEEE, and the computational programming is then developed in Lingo 11.0. Finally, a hypothetical example is presented in order to enable the understanding of the model in practice. View full abstract»

    This paper presents a procedure for integrating physiological signals (and EEG in particular) into gameplay on a mobile device. In HCI (Human-Computer Interaction) research there is a great interest in what the next innovation in game interaction will be - many are betting on physiological input; others on user-based game adaptation. Thus this paper combines both approaches and addresses user-based adaptation from physiological signals. We have designed a reusable, flexible and generalizable framework for mobile physiological games with the aim for supporting adaptive game development. The research mostly focuses on educational games for children with dyslexia. Our primary purpose is to improve the efficiency of these applications by improving educational learning in children.

    Mobile computer technology has greatly evolved in recent years. Cloud computing is recognized to be a new area for solving performance issues. Mobile terminals can take advantage from cloud computing. To cope with these new resources and fulfil new quality and performance requirements more sophisticated architecture and resource management are necessary. A mobile resource management architecture that uses cloud computing resources strongly relies on network bandwidth. Unfortunately wireless communication currently offers less bandwidth with more latency. To overcome this possible bottleneck parallel usage of network interfaces are feasible. In this paper mobile resource management using network aggregation technique is presented. View full abstract»

    In this paper we analyze the anonymous reports provided by our Android based BitTorrent client called DrTorrent. This application is available for free and is a full featured torrent client. The reports allow us to analyze the usage patterns typical for mobile torrent clients. As the mobile devices have some special properties like processing power, energy, and bandwidth limitations, the behavior differs from the traditional desktop clients. Beside the several statistics on for instance the sizes of accessed torrents and download times, we present parametric estimation models for the number of peers for a given torrent, and for the rate of peers which can be successfully connected to. This research can be considered as a pioneer work in the field of analyzing large peer-to-peer networks in modern mobile environments. The described measurement results enable to understand the mobile BitTorrent behavior in details and the proposed models can be used also as a base model for designing other mobile peer-to-peer services.

    Social networking applications are one of the main sources of content in the current internet, where currently the most of the traffic is composed of transferring text and still images. In the near future it is expected that members (users) of social networks will move to richer media, generating and consuming a large variety of multimedia content within these networks, thus Future Internet should be prepared to handle such demands. The underlying user community drives the media consumption and determines the network conditions in such cases. Proper modeling of the user community within such a system would make possible the accurate evaluation of the impact of these applications. Content generated by live media sharing communities differs from stored video content available online for streaming or download (e.g., NetFlix, YouTube, etc.) and the underlying user pattern is different, as well. In this paper we identify the key aspects of user communities in live multimedia distribution systems and investigate statistical features of each aspect. We have collected and analysed data from different live video portals and show that the statistical features of different portals follow similar trends. View full abstract»

    Digital technology is transforming business in many sectors, including restaurant systems and service processes. Customers may recognize the replacement of paper-based menus with digital ones as a first step of this process. Intelligent restaurant systems are an interesting application area for merging and extension of cognitive capabilities with both intra-cognitive and inter-cognitive communication. An intelligent restaurant system Smartmenu, developed by Centria and Delitaz Ltd., is an example of innovation which is based on merging and extending of cognitive capabilities. These kinds of systems may change the everyday life in restaurants in the future. The system covers the whole order process of a restaurant including the applications of the customer, the waiter, the kitchen and the cashier. The first pilot systems were recently tested in several restaurants in Finland. Piloting included also questionnaires and interviews analyzed by usability experts. In the future, Smartmenu may be extended to include also service robots in the system. The first demonstrations of using service robot in a restaurant environment were already carried out.

    This research aims at finding how suspects in police interrogations express their interpersonal stance -in terms of T.Leary's interpersonal circumplex- through body postures and facial expressions and how this can be simulated by virtual humans. Therefore, four types of stances were acted by eight actors. To see if the resulted postures are valid, short recordings were shown online in a survey to subjects who were asked to describe them by a selection of a number of adjectives. Results of this annotation task show that some stance types are better recognized than others. Validity (recognizing the intended stance) and inter-rater agreement do not always go hand in hand. The body postures and facial expressions of the best recognized fragments are annotated so they can be implemented in the artificial agent. The results of this study are used in a serious game for police interrogation training where the role of the suspect is played by an artificial embodied conversational agent. View full abstract»

    This paper introduces a concept of a completely automatic cargo containers cleaning system design. The cargo container cleaning system until now is implemented by human workers with manual cleaning equipment. However, such a system still has a disadvantage: worker's interaction with the container inside. This is prohibited by both World Health Organization and European Union [1]. The main goal of our research is to design a new modern and reliable mechanical system along with the capability to capture human interaction while executing the washing task. The main steps of the research include: investigation of the existing types of drivers and mechanical structures; further implementation of the selected components and discussion of interaction with washing machine and the human operator.

    Three different cases are presented in this paper, they describe how product development are conducted in micro-sized companies. All companies have novel ideas that they strive to realize into an engineered product and in some cases they also provide an integrated service. Typically, product development literature emphasizes systematic development processes to sustain viable businesses. Often a phased process is suggested as the optimal model. We have found that viable micro-sized companies do not employ such processes, but rather what, seemingly, is an ad-hoc procedure for each type of solution. By doing so they face challenges to grow and to upscale the production. A key result from this study is the finding of a gap between current product development literature and the actual needs of micro-sized firms. View full abstract»

    Provisioning 3D video stream-based services online in an acceptable quality, even in a wireless access environment, is a big challenge for Future Internet service providers. Only few empirical results are known about the user perceived quality of these kinds of services. In this paper we describe a statistical analysis of the relationship between Quality of Experience and service attributes for active 3D live streaming, which was carried out in a real home scenario via an IEEE 802.11n standard based Wi-Fi access available for transferring data at the customer side. 90 participants took part in this investigation who watched 20 test cases of the full reference based subjective quality test suffering Quality of Service degradations, Wi-Fi TX-Power value changing and existence of secure and not secure (i.e., with and without IPsec) 3D video delivery. QoE was also affected by human factors like acceptance rate of 3D technology by the participants and their prior technical knowledge and experience, which could cause dissonant states of cognitions. The investigation presented here could help in the design of future QoE-aware 3D video streaming systems. View full abstract»

    Using a smartphone become the part of our everyday life in the last few years. These devices can help us in many areas of life (sport, job, weather etc.), but sometimes can be also very annoying because of the battery life time. That is why it is very important to find solutions, which can reduce the energy consumption of the smartphones. One possible method is the “computation offloading” where a part of the processes are executed on a remote device (e.g. in the cloud). A lot of example has already shown, that computation offloading can reduce the energy usage of the mobile devices. However, the amount of energy saving may differ, as the decision making of the offloading process can be controlled with several techniques. Our decision making theory is based on the scheduling theory. In this paper, we are going to introduce a new system called ECGM (Energy efficient Code Generator for Mobile phones). ECGM decides automatically at compile time, which task should run on the smartphone and which task can be offloaded. The benefit of our system will be demonstrated through measurements based on our energy-efficiency scheduling technique. View full abstract»

    Extension of the human senses means not just the detection of changes by an artificial system, but also how that artificial sensory system can provide information about that to the human user. Warning signals serve the facilitation of detection of visual objects. We investigated how warning signals and signaled objects integrate into multimodal objects revealed by early evoked brain potentials. We asked whether locus of attention and stimulus intensity modulates this effect. 15 participants performed a driving and a redundant target paradigm task while EEG was recorded from scalp electrodes. We presented audio/visual/bimodal stimuli either with low or with middle intensity. We found that non-attended low intensity multisensory changes caused difference in attentional processing as early as 88 msec, on the other hand attended middle intensity multisensory stimuli led to an enhancement of an early visual event related potential component, namely the C1. These results suggest that attention and stimulus intensity interact in multisensory perception. Our results raise attention to how warning signals and signaled objects integrate. Consequently a warning system that is capable of providing simultaneous and spatially consequent signals is proposed. View full abstract»

    The proposed Intelligent Ice Protection System `IIPS' is the first version of the proposed methodology. It consists of one intelligent central command unit, one anti/deicing thermal unit, one direct ice detection/measurement unit (ice sensors) and one indirect ice prediction unit (metrological weather station and thermal infrared unit). The output of the intelligent central command unit primarily depends on the input of these units. The thermography sensor unit will be dependent on the feedback of the weather station unit. This unit supplies the output of surface temperature to the intelligent central unit which then controls the heating rate of the solution unit. View full abstract»

    This paper presents the analysis of automation hardware market, choosing and implementation of an optimal device to create remote supervision of workshops. An idea to create a remotely controllable workshop is not new, but the challenges with interaction scenarios between machines (CNC machines, industrial robots) and humans became more and more complex. Nowadays, industrial automation is mainly organized by microcontroller systems and the main disadvantages of such systems is focusing on specific tasks, needs of external personal computer and advanced level of user's programming skills. Thus, the main aim of the research is to review the existing open source computing devices in order to find an optimal hardware to enable introduction of novel interaction methodologies such as cognitive info-communication through the services of iSpace.
