Inventing and devising movement in the design of movement-based interactive systems
Authors: Lian Loke, Toni Robertson
Venue: Proceedings of the 20th Australasian Conference on Computer-Human Interaction: Designing for Habitus and Habitat (2008)

This paper reports on a study that explored ways of inventing and devising movement for use in the design of movement-based interaction with video-based, motion-sensing technologies. Methods that dancers, trained in movement improvisation and performance-making, used to choreograph movement were examined as sources of potential methods for technology designers. The findings enabled us to develop methods and tools for creating and structuring new movements, based on felt experience and the creative potential of the moving body. These methods and tools contribute to the ongoing development of a design methodology underpinned by the principle of making strange. By making strange, we mean ways of unsettling habitual perceptions and conceptions of the moving body to arrive at fresh appreciations and perspectives for design that are anchored in the sensing, feeling and moving body.
Reliability and performance analysis of new fault tolerant irregular network
Authors: Rith Mahajan, Renu Vig
Venue: WSEAS Transactions on Computer Research (2008)

A lot of work and analysis has been done on regular fault-tolerant MINs but irregular MINS have the inherent concept of favorite memory module offering lower latency. The multipath nature of these networks provides a non-blocking operation. This work introduces a new network, named as MFT-2 network, which contributes fault-tolerance by providing dynamic full-access capability in the presence of faults. MFT-2 network is improvement on irregular Four Tree network (FT). In case of any fault the system is reconfigured which operates in a degraded mode owing to the increased latency. But this approach minimizes the overheads of providing fault-tolerance, both in terms of cost and performance, during normal operation of the system. Irregular nature of these networks has reduced latency, improved dynamic fault-tolerant routing, high reliability and performance. The probabilistic approach is used to analyze the MINs based on independent request assumptions.
XML technologies for the Omaha System: A data model, a Java tool and several case studies supporting home healthcare
Authors: Pierpaolo Vittorini, Antonietta Tarquinio, Ferdinando di Orio
Venue: Computer Methods and Programs in Biomedicine (2009)

The eXtensible markup language (XML) is a metalanguage which is useful to represent and exchange data between heterogeneous systems. XML may enable healthcare practitioners to document, monitor, evaluate, and archive medical information and services into distributed computer environments. Therefore, the most recent proposals on electronic health records (EHRs) are usually based on XML documents. Since none of the existing nomenclatures were specifically developed for use in automated clinical information systems, but were adapted to such use, numerous current EHRs are organized as a sequence of events, each represented through codes taken from international classification systems. In nursing, a hierarchically organized problem-solving approach is followed, which hardly couples with the sequential organization of such EHRs. Therefore, the paper presents an XML data model for the Omaha System taxonomy, which is one of the most important international nomenclatures used in the home healthcare nursing context. Such a data model represents the formal definition of EHRs specifically developed for nursing practice. Furthermore, the paper delineates a Java application prototype which is able to manage such documents, shows the possibility to transform such documents into readable web pages, and reports several case studies, one currently managed by the home care service of a Health Center in Central Italy.
TDM virtual-circuit configuration for network-on-chip
Authors: Zhonghai Lu, Axel Jantsch
Venue: IEEE Transactions on Very Large Scale Integration (VLSI) Systems (2008)

In network-on-chip (NoC), time-division-multiplexing (TDM) virtual circuits (VCs) have been proposed to satisfy the quality-of-service requirements of applications. TDM VC is a connection-oriented communication service by which two or more connections take turns to share buffers and link bandwidth using dedicated time slots. In the paper, we first give a formulation of the multinode VC configuration problem for arbitrary NoC topologies. A multinode VC allows multiple source and destination nodes on it. Then we address the two problems of path selection and slot allocation for TDM VC configuration. For the path selection, we use a backtracking algorithm to explore the path diversity, constructively searching the solution space. In the slot allocation phase, overlapped VCs must be configured such that no conflict occurs and their bandwidth requirements are satisfied. We define the concept of a logical network (LN) as an infinite set of associated (time slot, buffer) pairs with respect to a buffer on a given VC. Based on this concept, we develop and prove theorems that constitute sufficient and necessary conditions to establish conflict-free VCs. They are applicable for networks where all nodes operate with the same clock frequency but allowing different phases. Using these theorems, slot allocation for VCs is a procedure of assigning VCs to different LNs. TDM VC configuration can thus be predictable and correct-by-construction. Our experiments on synthetic and real applications validate the effectiveness and efficiency of our approach.
Optimized and quality improved incoherent optical fiber bundle calibration method for image transmission
Authors: O. Demuynck
Venue: Proceedings of the 8th conference on Signal processing, computational geometry and artificial vision (2008)

Artificial vision, in spite of all theoretical and practical progress accomplished during last thirty years, still cannot be employed technically in some hazardous and strong industrial areas, where conditions are such that cameras would not operate properly. Alternatives on such problem are the quite recent IP65 and IP67 industrial cameras, and associated connectors, protected by an anticorrosive, waterproof, and high temperatures resistive carcass employing a dedicated electronic, in addition robust to almost 3G accelerations. Nevertheless, such cameras are still very expensive compared to conventional industrial cameras and would still not be enough in hardest conditions (explosive gas or dust environment) or in electromagnetic interferences environments. A good alternative in extreme conditions is the use of optical fiber bundle. Since such cable only transmits light, they intrinsically have electromagnetic interferences immunity and depending on the fiber material could be exposed to very high temperature (over 1000°C for sapphire fibers for example), could be employed in almost all corrosive environment, and are totally submersible. Nevertheless, the coherent optical fiber bundles are very expensive, and for large distances could be non-competitive facing the other hardware solutions. Thus, the best suitable option to develop a competitive system in those particular cases is the use of incoherent optical fiber bundle (IOFB), nowadays just employed for illumination tasks. Image transmission in this case is not direct but require a calibration step that we discuss in this paper. We propose in this work on a new calibration method of incoherent optical fiber bundle (IOFB) for image transmission purpose. First, we present the calibration method (an enhancement of previously published calibration methods), some resulting reconstructed images and a discussion on its quality improvement employing simple denoising methods. We finally depict the two new post calibration methods that efficiently refine the reconstruction Look Up Table (LUT) used for the output image reconstruction. Those two post calibration method are: correction of the input plan chromatics aberrations, and extraction of a unique pixel (almost centered) for each fibers.
Study of magnetic impurity as defects in ZnO grown by pulsed laser deposition
Authors: Jae-Hoon Kim, Hooyoung Song, Eun Kyu Kim
Venue: Microelectronics Journal (2009)

The structural, electrical and magnetic properties of Zn"0"."9"5Mn"0"."0"5O films grown by a pulsed laser deposition system were studied. An X-ray diffraction was tried to verify a crystal structure of the sample. A capacitance-voltage measurement showed that the Zn"0"."9"5Mn"0"."0"5O has electrical properties of an n-type semiconductor, and its carrier concentration appears 5x10^1^8cm^-^3. From a deep level transient spectroscopy measurement, an oxygen vacancy and a Mn-related electron trap in the Zn"0"."9"5Mn"0"."0"5O films were appeared as E"c-0.62eV and E"c-0.13eV, respectively. A magnetic hysteresis of ferromagnetic was measured in the Zn"0"."9"5Mn"0"."0"5O at temperature of 15K. The hydrogen plasma-annealed sample had larger magnetization than non-annealed sample because of interstitially located hydrogen atoms-mediated double exchange interaction.
Natural computing methods in bioinformatics: A survey
Authors: Francesco Masulli, Sushmita Mitra
Venue: Information Fusion (2009)

Often data analysis problems in Bioinformatics concern the fusion of multisensor outputs or the fusion of multisource information, where one must integrate different kinds of biological data. Natural computing provides several possibilities in Bioinformatics, especially by presenting interesting nature-inspired methodologies for handling such complex problems. In this article we survey the role of natural computing in the domains of protein structure prediction, microarray data analysis and gene regulatory network generation. We utilize the learning ability of neural networks for adapting, uncertainty handling capacity of fuzzy sets and rough sets for modeling ambiguity, and the search potential of genetic algorithms for efficiently traversing large search spaces.

Authors: Muhammad Zaheer Aziz, Bärbel Mertsching
Venue: Attention in Cognitive Systems: 5th International Workshop on Attention in Cognitive Systems, WAPCV 2008 Fira, Santorini, Greece, May 12, 2008 Revised Selected Papers (2009)

Every field of science requires standardization of metrics and measurement methods for detecting true advancement in research. Efforts on computational models of visual attention models have increased in the recent years and now it is important to have standard measuring techniques in this area in order to avoid undue deceleration in its progress. This paper performs a review of the evaluation techniques used by different researchers in the field and brings them in an organized structure. Further methods and metrics are also proposed that would lead to more objective and quantitative evaluation of the attention models.
A new technique to optimize the functions of fuzzy profit of queuing models: Application to a queuing model with publicity and renouncement
Authors: María José Pardo, David de la Fuente
Venue: Computers Mathematics with Applications (2009)

In this paper we model, using the Queuing Theory, the situation in which the manager of some facilities wishes to maximize the profit generated by the same. The manager tries to attract customers and the effectiveness of his publicity politic is measured in the fraction of customers who renounce. In this paper, unlike the classic models, we consider that the service time of the only server of the facilities behave with uncertainty, which may be represented by means of a fuzzy number. The objective is to determine the rate to be paid by every customer for his service and the level of publicity which the manager must utilize to maximize his profits. The consideration of service times as fuzzy numbers implies that the function to be optimized has fuzzy coefficients, this is why it is necessary to use fuzzy optimization for the solution of the problem and, in addition, a new technique is proposed in order to optimize the functions of fuzzy profit of queuing models. To demonstrate the validity of the proposed proceeding is resolved satisfactorily, and applied as an example, a system of fuzzy queues, which is often found in real situations. The fuzzy queuing systems are more realistic than the crisp systems commonly used in many practical situations. Besides, the extension of the queuing decision models to fuzzy environment allows these models to have further applications.
Exploiting colored Petri nets to decide on permutation admissibility
Authors: Rza Bashirov, Fabrice Kordon, H&#x00fc;seyin Lort
Venue: Acta Informatica (2009)

In this work, we propose an innovative approach to investigate the admissibility of permutations to multistage interconnection networks&#x2014;a challenging problem of switching theory. The proposed approach is centered upon modeling of multistage interconnection networks with colored Petri nets and use of Petri net analysis tools such as the unfolding technique and the invariants method. To assess the feasibility of the proposed approach we demonstrate that the complete unfoldings obtained in this work are polynomial in the problem size and employ an acyclic structure. The approach takes advantage of easy to use, yet extremely efficient, software tools.
Multimodal selection techniques for dense and occluded 3D virtual environments
Authors: Lode Vanacken, Tovi Grossman, Karin Coninx
Venue: International Journal of Human-Computer Studies (2009)

Object selection is a primary interaction technique which must be supported by any interactive three-dimensional virtual reality application. Although numerous techniques exist, few have been designed to support the selection of objects in dense target environments, or the selection of objects which are occluded from the user's viewpoint. There is, thus, a limited understanding on how these important factors will affect selection performance. In this paper, we present a set of design guidelines and strategies to aid the development of selection techniques which can compensate for environment density and target visibility. Based on these guidelines, we present new forms of the ray casting and bubble cursor selection techniques, which are augmented with visual, audio, and haptic feedback, to support selection within dense and occluded 3D target environments. We perform a series of experiments to evaluate these new techniques, varying both the environment density and target visibility. The results provide an initial understanding of how these factors affect selection performance. Furthermore, the results showed that our new techniques adequately allowed users to select targets which were not visible from their initial viewpoint. The audio and haptic feedback did not provide significant improvements, and our analysis indicated that our introduced visual feedback played the most critical role in aiding the selection task.
An investigation into the use of field methods in the design and evaluation of interactive systems
Authors: Kelly Monahan, Mia Lahteenmaki, Sharon McDonald, Gilbert Cockton
Venue: Proceedings of the 22nd British HCI Group Annual Conference on HCI 2008: People and Computers XXII: Culture, Creativity, Interaction - Volume 1 (2008)

This paper reports the results of an international web-based survey on the use of field studies in the design and evaluation of interactive systems, which was conducted between December 2006 and February 2007. The results suggest that the advantages and disadvantages of field methods are generally well understood, but guidance is needed in their application and use. Field studies were most frequently used for understanding context, and respondents preferred a more varied approach to method use rather than following a defined methodology such as Contextual Design. Observations were rated as the most effective technique overall, although interviews appeared to be more frequently used. Significant areas of further improvement for field methods were identified as improvements in data collection/analysis tools and improvements in adaptability of methods.
Improvement of turbo decoding using cross-entropy
Authors: Erl-Huei Lu, Yi-Nan Lin, Wei-Wen Hung
Venue: Computer Communications (2009)

In this paper, we present a simple method for normalizing the output information produced by a turbo decoder. The method is devised based on the cross-entropy (CE) concept. Simulations comparing the new method with some widely used normalization techniques show that the proposed approach can achieve about 0.2~0.3dB coding gain improvement on average while reducing up to about 1/2~2/3 iteration for decoding, but require much fewer and simpler computations.
An Operation-Based Communication of Spatial Data Quality
Authors: Amin Zargar, Rodolphe Devillers
Venue: Proceedings of the 2009 International Conference on Advanced Geographic Information Systems & Web Services (2009)

Improving users' awareness of the imperfections in spatial data has been a research issue explored within Geographic Information Sciences (GIS) for more than 30 years. However, little practical progress has been made toward this objective. Currently, most spatial data producers document information about spatial data quality as part of metadata. However, this information remains largely ignored by GIS users, which leads to the risk of users making poor decisions based on spatial data. As users increasingly make use of various GIS functionalities, GIS still lack the necessary mechanisms to effectively warn the users of the existence of quality issues in the spatial data being used. This becomes even more problematic in a web environment where data and services of unknown qualities can be shared and combined in the same application. In this paper we present an approach which aims at improving the use of quality information by providing it to the users in a more efficient way than existing approaches used for consulting metadata. We use an operation-based approach to link data quality information to the individual operations used in GIS applications. A conceptual framework for associating quality information with GIS operations is presented. Then, a prototype implementing this concept into a GIS software is described and discussed.

The ways of capacity planning and performance scaling techniques of database server are discussed. This paper also provides the method of how to scale database server for a population information system with mass data based on rPerf data model to comply with the performance requirement. The computing process and scaling techniques used in this paper can be referable for other capacity estimating of servers on which the application systems are running with a large amount of data.
Pulse Vector Magnetic Potential and Its Influence on Live Cells
Authors: Ivan Rampl, Vladimír Boudný, Milan Cíž, Antonín Lojek, Pavel Hyršl
Venue: Proceedings of the 2009 International Conference on eHealth, Telemedicine, and Social Medicine (2009)

The paper is devoted to the results of biophysical experiments by which the existence of the field of so called pulse vector magnetic potential was successfully proved. The decision to carry out these tests was motivated by a favorable coincidence of pieces of knowledge obtained in the solution of other biophysical-research projects. The aim of the original experiment was only to check whether the field of pulse vector magnetic potential was detectable via a chosen biophysical way, when the live cells by their life manifestation would play the role of sensors of the presence of this field. After the discovery of the surprising behavior of live cells irradiated by the pulse vector magnetic potential (with the presence of exciting pulse magnetic field excluded), specific research was started into both its influence on various biological materials, using further in vitro methods, and in the direction of understanding the physical nature of this biophysical phenomenon. The research is only at the beginning but interesting results can already be reported that are worthy of the attention of wider professional public.
The integration of home-automation and IPTV system and services
Authors: Mark Umberger, Iztok Humar, Andrej Kos, Joe Guna, Andrej emva, Janez Bešter
Venue: Computer Standards Interfaces (2009)

In this paper we propose the integration of a home-automation system and its services (HASS) with an IPTV system and its services (IPTVSS) to enable convergence at the network-technology and user-interface levels. The convergence at the network-technology level was achieved by using the Internet protocol (IP), and therefore both integrated systems have to provide IP connectivity. To enable communication between the HASS and the IP-based services, we have implemented the WebService/Konnex gateway. The IPTVSS are IP based; therefore, an easy convergence at the network-technology level is possible. The convergence at the user-interface level was achieved by a hardware and software user-interface implementation.

Venue: Proceedings of the 3rd WSEAS international conference on Computer engineering and applications (2009)

The grid is to integrate the whole Internet into one set of huge super computer, realizing overall share of various resources. Grid is a new network that can bring huge storage processing and storage capacity and other IT resources. The grid computing can link a great number of computers in different locations via share network and thus form a virtual super computer t which combines idle capacity processor in the computers in many locations and provide huge processing ability for the research and centralized application of other data. The high-efficient management of grid resources and high-efficient scheduling of tasks are the important contents in today's net grid research. In this article we divide the tasks into some small tasks assigned with scheduling priorities for each level, and then slice all resources in network into some time slices assigned with resource priorities according to trust mechanism. It promotes the effectiveness and high-efficiency by arranging task scheduling and resource scheduling in priority.

Venue: Proceedings of the 4th ACM/IEEE international conference on Human robot interaction (2009)

We report results of a study in which a low cost sociable robot was immersed at an Early Childhood Education Center for a period of 2 weeks. The study was designed to investigate whether the robot, which operated fully autonomously during the intervention period, could improve target vocabulary skills of 18-24 month of age toddlers. The results showed a 27 % improvement in knowledge of the target words taught by the robot when compared to a matched set of control words. The results suggest that sociable robots may be an effective and low cost technology to enrich Early Childhood Education environments.
