Collaborative Annotation Creation and Access in a Multimodal Environment with Heterogeneous Devices for Decision Support and for Experience Sharing
Authors: Charles Robert
Venue: Proceedings of the 2008 IEEE International Conference on Sensor Networks, Ubiquitous, and Trustworthy Computing (sutc 2008) (2008)

The importance of annotation as personal expression of individuals on documents of interest can not be over emphasized in decision support systems and experience sharing. An annotation model (AMIE: Annotation model for information exchange) proposed the integration of the peculiarity of annotation creator for decision making. The fact that annotation can assist in decision making was well discussed in AMIE. If annotation is to be used for decision support, peculiarity of decision maker must be given proper attention specifically when it has to do with collaborative efforts. It is a known fact that more and more decision makers are favored to the use of divergent access to information devices including PDA and other non convectional devices. Possibility of information access specifically in annotation through divergent sources must be considered with substantial attention. The work gave a reviewed description of AMIE model in relation to divergences of information sources. It presented efforts made in making annotation available across divergent devices in a collaborative environment for decision making and for experience sharing. The platform of Microsoft visual studio dot net was used to experiment the proposal. Database running on SQL server CE from PDA was synchronized to the standard SQL server to permit divergent information creation and access.

Authors: Akinori Uchiyama, Masaji Nishimura, Mitsuyuki Amata, Takashi Mashimo, Yuji Fujino
Venue: Technology and Health Care (2007)

The aim of the study was to assess a new expiratory support (ES) system in resolving air trapping in the lungs during mechanical ventilation. The ES system consisted of a cylinder and two valves that were connected to the ventilatory circuit. The movements of them were synchronized with the ventilator. The cylinder aspirated gas during expiration. We compared the effects of the ES on air trapping between a narrower and an ordinary size endotracheal tube (ETT) (internal diameter (ID): 5 and 8 mm). In addition, we compared the effects of the ES on air trapping between normal and high airway resistance of the lungs (5 and 20 cm H$_{2}$O/L/s). The ventilatory settings were as follows: volume controlled ventilation with constant inspiratory flow rate; tidal volume, 0.5 L; inspiratory time, 1.0 s; expiratory time, 1.0, 1.5, or 2.0 s; and PEEP, 0 cm H$_2$O. The ES normalized the end-expiratory alveolar pressure of the 5 mm ID ETT at a level similar to that of the 8 mm ID ETT. The ES also resolved the air trapping induced by the high airway resistance of the lungs. In conclusion, the ES system resolved the air trapping associated with a narrow endotracheal tube and high airway resistance of the lungs.

Authors: Arianit Kurti, Daniel Spikol, Marcelo Milrad
Venue: International Journal of Mobile Learning and Organisation (2008)

In this paper, we present our design approach for bridging outdoors and indoors learning activities with the support of mobile and positioning technologies. In order to illustrate these research efforts we describe the outcomes of two trials we have conducted with more than 50 elementary school children. The activities presented in this paper aspire at supporting the notion of situated learning with mobile and positioning technologies to promote new ways of collaboration based on the users' learning context. The results of our experiments indicate that children enjoyed learning where mobile devices are used in situ, supporting the learning activities in the context of which they are taking place.
Evaluating a breadth-first cs 1 for scientists
Authors: Zachary Dodds, Ran Libeskind-Hadas, Christine Alvarado, Geoff Kuenning
Venue: Proceedings of the 39th SIGCSE technical symposium on Computer science education (2008)

This paper presents a thorough evaluation of CS for Scientists, a CS 1 course designed to provide future scientists with an overview of the discipline. The course takes a breadth-first approach that leverages its students' interest and experience in science, mathematics, and engineering. In contrast to many other styles of CS 1, this course does not presume that its students will study more computer science, but it does seek to prepare them should they choose to. We summarize the past year's worth of assessments of student learning, retention, and affect -- with particular attention paid to women's voices. Where possible, we contrast these student measures with those from a traditional, imperative-first CS1 that this new course replaced. The data thus far suggest that CS for Scientists significantly improves students' understanding of CS, its applications, and practice.
Authenticated out-of-band communication over social links
Authors: Anirudh V. Ramachandran, Nick Feamster
Venue: Proceedings of the first workshop on Online social networks (2008)

Many existing host-based applications rely on their own authentication mechanisms and peer discovery services. Although social networking sites already provide mechanisms for users both to discover other users (e.g., by logging on to the social network Web site) and to communicate securely with each other (e.g., using instant messages within the social networking site), today's applications have no way to exploit the relationships and trust that are inherent in these networks. This paper proposes Authenticatr, a framework that allows applications to use the authentication and peer discovery mechanisms inherent in social networking sites to bootstrap their own authenticated communication channels. We describe motivating applications, detail the interface that Authenticatr exposes to applications, and discuss practical considerations and security threats.
An industrial network flow information integration model for supply chain management and intelligent transportation
Authors: C. Hsu, W. A. Wallace
Venue: Enterprise Information Systems (2007)

Industrial network flow involves three domains: infrastructure, individual subjects of movement, and planning and control of the movement. Examples include supply chain and intelligent transportation. These traditionally isolated domains can be digitally connected to enhance their performance. Digitization of the infrastructure provides real-time data to facilitate its operation, while digitally connecting the subjects to the infrastructure allows for tailored services and support to particular subjects. Connection of both to the enterprise information systems enables adaptive control for the application (e.g. logistics) at a global optimization level. Previous results in the field cover separate aspects of planning/routing, real-time monitoring, and trip support. Toward this end, a new highway-based subject-infrastructure-enterprise (SIE) information integration model using digital connection is proposed to the field of industrial network flow control for application to intelligent transportation and supply chain management. The SIE model supports industrial network flow control in a way comparable to an adaptive control panel administering an automated material handling system. In this metaphor, the global infrastructure becomes 'controllable' similar to factory conveyors and automated guided vehicles. This paper presents a conceptual design substantiated with information requirements analysis. An empirical experiment at locations in New York State shows the technical feasibility of the digital connection envisioned.

IPOSA: A Novel Slack Distribution Algorithm for Interconnect Power Optimization
Authors: Xiang Qiu, Yuchun Ma, Xiangqing He, Xianlong Hong
Venue: Proceedings of the 9th international symposium on Quality Electronic Design (2008)

As CMOS technology scales continually, interconnect powerhas become a significant part of total chip power. Without compromising performance, timing slacks can be utilized to optimize interconnect power efficiently. The optimization of total interconnect power is affected not only by the properties of each interconnect as well as the timing constraint, but also by the circuit topology. In this paper, we introduce a novel slack distribution algorithm IPOSA to optimize interconnect power efficiently. A piecewise linear model is proposed to quantify therelationship between interconnect power reduction and timing slack amount, considering the interconnect length and the switching activity. Monte Carlo analysis shows our piecewise model is accurate enough that the average error is 1.7%. Based on the piecewise linearity of the model,we propose an iterative slack distribution algorithm which minimizes total interconnect power with given performance constraint. The experimental results show that our algorithm can achieve 41.7% interconnect power reduction on average.
Performance Evaluation of Large Scale Disaster Information System over Japan Gigabit Network
Authors: Hiroyuki Echigo, Yoshitaka Shibata
Venue: Proceedings of the 22nd International Conference on Advanced Information Networking and Applications - Workshops (2008)

Since various disasters provides serious damage influence at the time to many residents in wide area across Japan island, large scale of disaster information system with more robustness and redundancy covered over wide area is required. In this paper, we introduce a large scale distributed resident-oriented safety information system constructed over Japan Gigabit Network. The safety information with residents is registered to the local database in the evacuated area and integrated into an upper-layer database in the district area. Those local databases are mutually covered when the some of the databases are destroyed or disordered. On the other hand, the upper-layer databases are located to mutually different locations with long distance to isolate the influence to the same disaster and also mutually mirrored to support when the some of them are out of order. Thus, by introducing two levels of redundancy and backup functions, more large scale and robust safety information database system can be realized. In this paper, we designed and implemented a prototype system by our introduced method over Japan Gigabit Network to evaluate whether our suggested method is useful or not. Through the functional and performance evaluation, we could verified our suggested resident information system is effective and useful.
Partial difference equation and the maximum principle
Authors: Jiří Gregor
Venue: Proceedings of the 5th WSEAS International Conference on Applied Mathematics (2004)

Linear equations in partial forward and backward differences for functions in n independent variables (partial difference equations or PΔE's) on arbitrary non-finite subsets A ⊂ Zn are considered. To estimate the growth of the solution its recursive construction is used. This construction allows to prove a statement, which we call the maximum principle: under certain conditions the values of the solution are bounded by the norm of the initial values (in the homogeneous case), or bounded by the norm of the input (in the nonhomogeneous case with zero initial values). Such maximum principle is further applied to obtain various growth estimates. Examples include growth estimates for Stirling numbers, Euler numbers, coefficients of orthogonal polynomials and other sequences defined by PΔE's.
Note: Partition identities and the coin exchange problem
Authors: Alexander E. Holroyd
Venue: Journal of Combinatorial Theory Series A (2008)

The number of partitions of n into parts divisible by a or b equals the number of partitions of n in which each part and each difference of two parts is expressible as a non-negative integer combination of a and b. This generalizes identities of MacMahon and Andrews. The analogous identities for three or more integers (in place of a,b) hold in certain cases.
The Basin of Mexico Hydrogeological Database (BMHDB): Implementation, queries and interaction with open source software
Authors: J. J. Carrera-Hernández, S. J. Gaskin
Venue: Environmental Modelling Software (2008)

Integrated Water Management at the Basin level is a concept that was introduced in the 1990s and is a goal in every national and local water management plan. Unfortunately this goal has not been achieved mainly due to a lack of both tools and data management, as data must be gathered from different sources and in different formats. Compounding this problem is the fact that in some regions different water agencies are in charge of water supply as is the case in the Basin of Mexico, in which Mexico City and its Metropolitan Zone are located. The inhabitants of the Basin of Mexico, which comprises five different political entities and in which different agencies are in charge of water supply rely on the Basin's aquifer system as its main water supply source. However, a regional hydrogeological database in this area does not exist which is why the use of both a Relational Database Management System (RDMBS) and a Geographic Information System (GIS) is proposed in order to improve regional data management in the study area. Data stored in this new database, the Basin of Mexico Hydrogeological Database (BMHDB) comprise data on climatological, borehole and run-off variables, readily providing information for the development of hydrogeological models. A simple example is used to show how geostatistical analysis can be done using the data directly from the BMHDB. The structure of the BMHDB allows easy maintenance and updating, representing a valuable tool for the development of regional studies.
Comparative analyses of the scaling diversity index and its applicability
Authors: T. -X. Yue, S. -N. Ma, S. -X. Wu, J. -Y. Zhan
Venue: International Journal of Remote Sensing (2007)

As well as the newly developed scaling diversity index, there are also eleven traditional diversity indices to be found in the literature. Analyses show that these eleven traditional indices are unable to formulate the richness component of diversity. In particular, the most widely used index, the Shannon-Weiner index, cannot express the evenness component. On the contrary, the scaling diversity index is able to formulate both the richness aspect and the evenness aspect of diversity. The scaling diversity index has been applied to developing scenarios of ecological diversity at different spatial resolutions and spatial scales. A case study in Fukang in the Xinjiang Uygur Autonomous Region in China shows that the scaling diversity index is sensitive to spatial resolution and is easy to understand. It is scientifically sound and could be operated at affordable cost.
A maximum likelihood method for an asymmetric MDS model
Authors: S. Saburi, N. Chino
Venue: Computational Statistics Data Analysis (2008)

A maximum likelihood estimation method is proposed to fit an asymmetric multidimensional scaling model to a set of asymmetric data. This method is based on successive categories scaling, and enables us to analyze asymmetric proximity data measured, at least, at an ordinal scale level. It enables us to examine not only the appropriate scaling level of the data, but also the appropriate dimensionality of the model, using AIC. Prior to or in fitting the asymmetric MDS model, it is important to verify that the data are sufficiently asymmetric. Some variants of symmetry hypotheses are developed for this purpose. Since the emphasis in our paper is not on hypothesis testing, but on model diagnosis, we compare several candidate models including models with these hypotheses based on a similar model comparison idea using AIC. The method is applied to artificial data and a set of friendship data among nations in East Asia and the USA. Relations to other methods are also discussed.
New binary representation in genetic algorithms for solving TSP by mapping permutations to a list of ordered numbers
Authors: Amin Mohebifar
Venue: Proceedings of the 5th WSEAS International Conference on Computational Intelligence, Man-Machine Systems and Cybernetics (2006)

There have been various representations used for encoding TSP tours in Genetic Algorithms. These representations, except binary representation, are forced to define their own crossover and mutation operators, and they cannot work with classical operators. In the other hand, in such cases, there is no guarantee that solutions, which obtained by crossover and mutation operators, are valid. So, we need some operation to repair chromosomes and transform invalid tours to valid tours. This operation is a time-consuming process. However binary representation is not recommended, in this paper we propose our binary representation based on mapping all possible solutions to a list of ordered binary representations which has some advantages.
Intelligent web-based learning system with personalized learning path guidance
Authors: Chih-Ming Chen
Venue: Computers Education (2008)

Personalized curriculum sequencing is an important research issue for web-based learning systems because no fixed learning paths will be appropriate for all learners. Therefore, many researchers focused on developing e-learning systems with personalized learning mechanisms to assist on-line web-based learning and adaptively provide learning paths in order to promote the learning performance of individual learners. However, most personalized e-learning systems usually neglect to consider if learner ability and the difficulty level of the recommended courseware are matched to each other while performing personalized learning services. Moreover, the problem of concept continuity of learning paths also needs to be considered while implementing personalized curriculum sequencing because smooth learning paths enhance the linked strength between learning concepts. Generally, inappropriate courseware leads to learner cognitive overload or disorientation during learning processes, thus reducing learning performance. Therefore, compared to the freely browsing learning mode without any personalized learning path guidance used in most web-based learning systems, this paper assesses whether the proposed genetic-based personalized e-learning system, which can generate appropriate learning paths according to the incorrect testing responses of an individual learner in a pre-test, provides benefits in terms of learning performance promotion while learning. Based on the results of pre-test, the proposed genetic-based personalized e-learning system can conduct personalized curriculum sequencing through simultaneously considering courseware difficulty level and the concept continuity of learning paths to support web-based learning. Experimental results indicated that applying the proposed genetic-based personalized e-learning system for web-based learning is superior to the freely browsing learning mode because of high quality and concise learning path for individual learners.
A Vector Transform Application on a Coding Algorithm Based on the Polarity of Speech Signal
Authors: Buket D. Barkana, Tamer Barkana
Venue: Proceedings of the Fifth International Conference on Information Technology: New Generations (2008)

In this study, a vector transform application on a coding algorithm based on the polarity of speech signal is presented. Vector transformation (VT) increases the intra vector correlation. Because of this property of VT, we expect the presented coding method will be improved. The coding algorithm compresses the signals around the positive and the negative peak values of the speech signal by removing reproducible portions of the signal while retaining reference signal portions that are enough to reproduce the original speech signal with a very small loss in quality. Before this coding algorithm, VT that is defined in Section 2 is applied on speech signals. Inverse VT is applied to decoded data. Obtained results are evaluated using graphics and SNR values.

Venue: Proceedings of the 4th WSEAS International Conference on Telecommunications and Informatics (2005)

Mobile ad hoc networks (MANET) are infrastructure less and stand-alone networks. This paper verifies the interworking between wireless and mobile ad hoc networks and the Internet. The communication is established with the help of access routers, which operate as gateways between the Manet and Internet. In this case the architecture of mobile internet router is studied that uses Mobile IP for mobility support across WLANs and MANETs is achieved through Mobile IPv6 (MIPv6). This paper presents a novel approach to integrate Wireless Local Area Networks (WLANs) and MANETs to the IPv6. Rout discovery and route maintenance is important parameter for connecting manets to internet.
