The aim of this paper is to explore new metaphors for interaction design on tabletop system. Tabletop systems are shared horizontal surface for co-located collaboration, which leads to original problems when designing interactions. We propose two metaphors based on the paper: the peeling metaphor, and the slot metaphor, and then suggest a way of using them to design new interactions for solving some of the problems of tabletop systems: documents organization, documents transmission and documents duplication.

Many design activities depend on communicative activities around collaboratively produced prototypes. A common communication practice in producing text documents is to add annotation in the form of comments. Previous research indicates that electronic paper-prototyping can be used to rapidly create simple prototypes of interactive systems, such as websites. Little is known, however, about how to provide and maintain variety of communication channels around such electronic paper-prototypes to enable end-users and other stakeholders to contribute to design dialogues. This paper presents Gabbeh, an electronic paper-prototyping tool, and reports on an evaluation using the tool in a simulated design exercise. [ABSTRACT FROM AUTHOR]

U-Healthcare promises increases in efficiency, accuracy and availability of medical treatment; however it also introduces the potential for serious abuses including major privacy violations, staff discrimination and even life-threatening attacks. In this position paper we highlight some potential threats and open the discussion about the security requirements of this new scenario. We take a few initial steps towards a U-Healthcare security policy and propose a system architecture designed to help enforce the policy's goals. [ABSTRACT FROM AUTHOR]

Global paper industry needs systems that can be used in all locations. International user studies can be helpful when integrating systems. Not only due to the lack of common language but also the differences in culture and the usage of systems, information from different countries needs to be collected and analyzed so that the integration development is not be biased and unilateral. During the study some food for thought was gathered on what to consider when planning an international user study. [ABSTRACT FROM AUTHOR]

We developed AirTransNote, a computer-mediated classroom collaboration system. The system enables real-time note-sharing. AirTransNote manages notes written by students on paper and enables the teacher to browse through the notes or show them to the students. AirTransNote can analyze students' answers, helping the teacher better understand their problems. The system is not meant to provide an alternative to the conventional way of instruction; rather, it is designed to enhance class interaction. We conducted a preliminary study using questionnaires and found that this system can be feasible to apply for classroom environment. [ABSTRACT FROM AUTHOR]

This paper reports the results of an in-depth study of Bluetooth naming practices which took place in the UK in August 2006. There is a significant culture of giving Bluetooth names to mobile phones in the UK, and this paper's main contribution is to provide an account of those Bluetooth naming practices, putting them in their social, physical and intentional context. The paper also uncovers how users have appropriated the ways in which Bluetooth, with its relatively short range of about 10-100m, operates between their mobile phones as a partially embodied medium, making it a distinctive paradigm of socially and physically embedded communication.

Content preparation is essential for web design [25]. The objective of this paper is to establish a theoretical foundation for the development of methods to evaluate the effectiveness of content preparation in information technology operations. Past studies identify information as the dominant concern of users, and delivery mechanism as a secondary concern [20]. The best presentation of the wrong information results in a design with major usability problems and does not aid the user in accomplishing his task. This paper shifts the focus of existing usability evaluation methods. It attempts to fill the void in usability literaoture by addressing the information aspect of usability evaluation. Combining the strengths of content preparation and usability evaluation yields major implications for a broad range of IT uses. [ABSTRACT FROM AUTHOR]

Due to the progress of Internet technology and the increase of distributed information on networks, the present knowledge management has been based more and more on the performance of various experienced users. In addition to the increase of electronic documents, the use of paper documents has not been reduced because of their convenience. This paper describes a method of tracking paper document locations and contents using radio frequency identification (RFID) technology. This research also focused on the expression of a task process and the seamless structuring of related electronic and paper documents as a result of task knowledge formalization using information organizing. A system is proposed here that implements information organization for both Web documents and paper documents with the task model description and RFID technology. Examples of a prototype system are also presented. [ABSTRACT FROM AUTHOR]

Papers in HCI play different roles, whether to inspire, solve industrial problems or further the science of HCI. There is a potential conflict between the different views, and a danger that different forms of validity are assumed by author and reader — deliberately or accidentally. This paper reviews some of the issues in this complex area and makes practical recommendations. In particular, the paper introduces the term "cross-validity" to help make explicit the issues, problems and means to tackle them. [ABSTRACT FROM AUTHOR]

This paper presents some future possibilities for eDemocracy tools and considers how these new technologies might conflict with our basic assumptions about what democracy should be. I hope this paper will contribute to discussion of under what situations different forms of eDemocracy are appropriate. The possibilities and repercussions of user profiling, voting outside of polling booths, longer decision-making periods, changeable election results and weighted voted are considered. Although none are necessarily advisable, this paper suggests they might be interesting to consider. [ABSTRACT FROM AUTHOR]

The Health-e-Child project aims to develop an integrated healthcare platform for European paediatrics. In order to achieve a comprehensive view of children's health, a complex integration of biomedical data, information, and knowledge is necessary. Ontologies will be used to formally define this domain knowledge and will form the basis for the medical knowledge management system. This paper introduces an innovative methodology for the vertical integration of biomedical knowledge. This approach will be largely clinician-centered and will enable the definition of ontology fragments, connections between them (semantic bridges) and enriched ontology fragments (views). The strategy for the specification and capture of fragments, bridges and views is outlined with preliminary examples demonstrated in the collection of biomedical information from hospital databases, biomedical ontologies, and biomedical public databases. Keywords: Vertical Knowledge Integration, Approximate Queries, Ontology Views, Semantic Bridges. [ABSTRACT FROM AUTHOR]

This paper follows up on an earlier study [1] by assessing the nature of 80 papers from EGOV 05 in terms of rigor and relevance criteria. Both studies use the same method and makes comparison between the results. We find that however still focusing overwhelmingly on descriptions and little on theory testing and creation, paper quality appears much better in that references to literature have increased grossly, there are very few dubious claims, philosophical research and theoretical arguments are virtually extinct, and the number of case stories is vastly reduced. However, the number of product descriptions is more than doubled to just over 30 %. The reasons for this are discussed, and as most of these papers are based on EU research funding we propose that an important reason may be the funding mechanism where researchers are employed as helpers in product development rather than critical scrutiny and analysis.

In this paper, we will propose our ideas for a semantically ready competency model. The model will allow semantic enrichment on different levels, creating truly meaningful competencies. The aim of this model is to provide a flexible approach for (re)use, matching, interpretation, exchange and storage for competencies. Our competency model is based on the DOGMA ontology framework and the proposed IEEE standards RCD and SCRM. We will focus on the model itself and how semantics can be applied to it as these elements form the basis for any kind of processing on them. Keywords: competence, competency, RCD, semantics, DOGMA, e-HRM, HRM, occupation, ontology, Semantic Web. [ABSTRACT FROM AUTHOR]

Transfusion Ontology is a simple task-based ontology developed in the emergency health care domain. Taking the assumption that ontologies are instruments for supporting exchange of information among parties, the principles governing the design of this ontology was mainly based on the identification of the interactions of messages to be exchanged among parties. This paper shows how this simple design principle is able to guide a whole ontology construction. [ABSTRACT FROM AUTHOR]

In this paper, a small case study is presented to illustrate our conceptual understanding of a task-based requirements process. We argue that sub-models as known in model-based design (e.g. task models, dialog models) support the reflection about an existing work situation at a conceptual level and allow a formal specification of requirements. However, it is also shown that the integration of complementary analysis approaches facilitates a richer consideration of social as well as technical aspects. An intertwined creation of models differing in their focus and in the degree of abstraction and formality supports a more effective requirements elicitation and elaboration. In addition, the paper discusses some crucial issues in task- and model-based design such as the ‘myth' of generalised task models, the different roles of task and dialog models, or the influence of intentions on models of current situations. We hope to contribute to a further clarification of the problem space. [ABSTRACT FROM AUTHOR]

Activity sensing in the home has a variety of important applications, including healthcare, entertainment, home automation, energy monitoring and post-occupancy research studies. Many existing systems for detecting occupant activity require large numbers of sensors, invasive vision systems, or extensive installation procedures. We present an approach that uses a single plug-in sensor to detect a variety of electrical events throughout the home. This sensor detects the electrical noise on residential power lines created by the abrupt switching of electrical devices and the noise created by certain devices while in operation. We use machine learning techniques to recognize electrically noisy events such as turning on or off a particular light switch, a television set, or an electric stove. We tested our system in one home for several weeks and in five homes for one week each to evaluate the system performance over time and in different types of houses. Results indicate that we can learn and classify various electrical events with accuracies ranging from 85-90%. [ABSTRACT FROM AUTHOR]

Today's mobile data applications aspire to deliver services to a user anywhere - anytime while fulfilling his Quality of Service (QoS) requirements. However, the success of the service delivery heavily relies on the QoS offered by the underlying networks. As the services operate in a heterogeneous networking environment, we argue that the generic information about the networks' offered-QoS may enable an anyhow mobile service delivery based on an intelligent (proactive) selection of ‘any' network available in the user's context (location and time). Towards this direction, we develop a QoS-predictions service provider, which includes functionality for the acquisition of generic offered-QoS information and which, via a multidimensional processing and history-based reasoning, will provide predictions of the expected offered-QoS in a reliable and timely manner. We acquire the generic QoS-information from distributed mobile services' components quantitatively (actively and passively) measuring the applicationlevel QoS, while the reasoning is based on statistical data mining and pattern recognition techniques.

In a community such as conferences, numerous service providers and service users exist, and people interact using contexts. With the improvements in context-awareness computing and mobile computing technologies, human-computer interactions for exchanging contexts started increasing. In this paper, we introduce some interaction techniques such as tag interaction and service discovery interaction using a mobile device to provide an efficient user interface to exchange contexts in a conference room. We identified typical situations in which these interactions can be used in a paper, poster session, and for providing individual information among the attendees. We analyzed the two interaction techniques to be suitable to improve the interactions for exchanging contexts in a conference. [ABSTRACT FROM AUTHOR]

A programming model for the automatic construction of USN applications based on Nano-Qplus is proposed in this paper. Nano-Qplus is a sensor network platform developed by ETRI. Programs of nodes such as sensors, routers, sinks and actuators in a sensor network are automatically generated through the technique of this paper. Developers can implement USN applications from models of sensor networks. The configuration information of each node is automatically generated from a model. Then, the execution code is automatically generated using the configuration information. Through the technique of this paper, developers can easily implement USN applications even if they do not know the details of low-level information. The development effort of USN applications also will be decreased because execution codes are automatically generated. Furthermore, developers can consistently construct USN applications from USN models using the proposed tool. [ABSTRACT FROM AUTHOR]

As in recent years, the focus of the ODBASE conference lies in addressing research issues that bridge traditional boundaries between disciplines such as databases, artificial intelligence, networking, data extraction, or mobile computing. There has been an increasing focus on semantic technologies in ODBASE. The work on semantic modeling technologies is being progressively scaled up to handling millions of triples which permit adoption of semantic applications within a few days. The envelope is being progressively pushed out to enable even faster, wider and broader enterprise-wide and Web-scale applications. Also, ODBASE 2007 encouraged the submission of papers that examine the information needs of various applications, including electronic commerce, electronic government, mobile systems, or bioinformatics.

This paper describes some results of a project that studied how multimedia can help the worker in an assembly task. The test case was a deep-cut assembly of a grid-anode for a cathodic protection system. A multimedia tool was implemented and compared with the conventional support method for the same task. The tool helps the worker by providing training and background information. During the task the tool acts as a guide and a set of well-defined instructions. The comparison of the methods was done by means of a field experiment. The results show that the use of the implemented tool helps to produce a slight increase to the quality of the work. However, the execution time of the work was not better when using the multimedia tool. According to a user questionnaire done in the test situation, the multimedia tool was more useful and easier to use, and gave the users more confidence than the conventional support method. It can be said that the use of multimedia support helps the worker to produce better quality in the task. [ABSTRACT FROM AUTHOR]

In order to discover services in business-driven Web service composition conveniently, accurately, and efficiently, this paper proposes a business process-oriented service discovery approach. In order to link business property with services, this paper proposes a business related description model of operations. Based on the business related relation model proposed in this paper, a relation-driven discovering algorithm for business process-oriented service discovery is presented. Compared with other discovering approach, the proposed discovering approach considers the business relation between operations and can solve the problem of discovering services with meaningful business relation. The experimentation shows the better performance of this algorithm. [ABSTRACT FROM AUTHOR]

The core content of action research (AR) is being able to solve organisational problems through intervention and to contribute to scientific knowledge. The main emphasis when discussing AR has been on the "research part". In this paper we focus on "action part" of AR in order to generate rigorous research, to solve local problems and to deal with evident dilemmas in AR. Action elements are addressed by situations in a project on one-stop government e-service development. As a result of the analysis action is illustrated. Action elements: action, actor, motive, space, time are analysed together with roles. The paper also shows a need to understand initiation, problem and situation addressing as an ongoing process in an AR project. A breakdown in the project is also highlighted and situations where problems discovers the action researcher and vice versa. [ABSTRACT FROM AUTHOR]

This paper introduces an analytical approach which is provided to calculate the downlink and uplink capacities of the time division duplex (TDD) system utilizing the underused frequency division duplex (FDD) uplink which shares the same frequency band. Then the ratio of downlink and uplink slots in one frame is adjusted, so as to prevent the radio resource waste due to asymmetric traffic characteristic in mobile multimedia services. The computer simulation shows that the resource waste problem can be considerably solved through the asymmetric slot allocation. Thus, this paper can be useful as a guideline in the course of planning a two-layer hierarchical cell structure (HCS) employing the TDD system as a microcell and FDD system as a macrocell as well as a mean to increase the performance of such a system.

In this paper we consider disaster management as the coordination of resources in space and time, and contrast this with the Joint Operational Picture (JOP) used in military planning. The basic premise is that the processes involved in the collection and management of information could interfere with the priorities of dealing with immediate demands on ‘rescuers' and their managers. Thus, we explore ways in which collaboration could be made as implicit as possible. The paper includes small-scale user trials of prototypes to highlight potential benefits and shortcomings. The paper concludes with consideration of how brokering approaches to coordination could be realized using the prototypes described in this paper. [ABSTRACT FROM AUTHOR]

The design of easy-to-use mobile systems for collecting and handling emergency medical care data in the field can significantly improve the effectiveness of rescue operations. In particular, this paper focuses on the design and evaluation of a mobile application that replaces ambulance run paper sheets. First, we discuss the limitations of traditional ambulance run paper sheets. Then, we present the PDA-based system we have developed. Finally, we discuss in detail the usability study we have carried out with first responders. [ABSTRACT FROM AUTHOR]

Across Europe emergency physicians are still using paper-based emergency report forms to document medical procedure at accident scenes. The forms are quite similar, but they differ in certain parameters or attributes. There are ongoing endeavours to combine the paper-based protocols and then transfer this new protocol standard into a software-based Emergency Patient Care Report Form (EPCRF). However during the transformation from a paper-based to an electronic solution, many problems occur. To keep the users' acceptance of the emergency medical services personnel, it is crucial that electronic EPCRF supports the central process efficiently. Therefore key elements within the emergency report form are the anatomical diagrams and the chronological sequence diagrams. These diagrams allow the emergency physician to track and record patient's parameters in a very fast and understandable and user friendly way. [ABSTRACT FROM AUTHOR]

The multiple viewed search engine presented here retrieves documents of an indicated search area and displays a matrix of the distribution of the clustering from two aspects of the retrieval result. The search engine provides a visual and semantic bird's-eye view of the entire retrieval result. In addition, the characteristic words of each cluster are displayed in the matrix, and supports narrowing of the search. Furthermore, it is possible to immediately change the analysis criteria or the number of clusters and to use a zooming function. Thus, various retrieval conditions for a query can be attempted immediately and continuously. As a case study, this paper performs several analyses on the electronic journal Zoological Science using a multiple viewed search engine. [ABSTRACT FROM AUTHOR]

Organisations want nowadays more controlled processes and easily usable solutions, but achieving them requires winning many challenges. Radio Frequency Identification (RFID) based technology has been proposed for improving mobile solution workflows and usability. NFC (Near Field Communication) technology is based on integrating RFID on mobile devices. This paper identifies how NFC based systems could be used to improve mobile solution workflows and usability. The results of this study are based on the implementation of six pilot cases in 2005-2007. This paper concludes that use of NFC provides both advantages and disadvantages and, therefore, to estimate the potential of NFC, its pros and cons have to be weighed up for each case in question. This paper also concludes that only a comprehensive solution achieves the full potential of NFC from users' point of view. Considering mobile solution usability, this paper concludes that NFC based solutions are easy to use, but the small and limited keyboard of mobile devices poses challenges to the design of these solutions. NFC use poses new organizational challenges like need for the rest of the system to catch up and feeling of distrust from the user side. [ABSTRACT FROM AUTHOR]

With the rise of RFID technology, the so called internet of things for managing supply chain events has gained increasing attention. This paper proposes a peer to peer broker network on top of existing specifications for this infrastructure. With the broker network, event based communication is enabled for the internet of things. However, the main contribution of this paper is a mechanism to optimize event queries for in-network processing of supply chain events. Here, models of supply chain processes are exploited for optimizing event queries and enabling improved mapping of query operators to the broker network. Experiments are presented which show that the proposed mechanism reduces network load compared to existing approaches. [ABSTRACT FROM AUTHOR]

Multimodal systems support people with different needs and different features during the interaction process making it more easy and natural. However naturalness can usually produce ambiguous interpretation. This paper discusses ambiguities in multimodal interaction proposing in particular two different examples of ambiguities: a) multimodal ambiguities produced combining un-ambiguous modal information containing contrasting concepts in multimodal dialogue, b) ambiguities arising by the propagation at multimodal level of a modal input ambiguity. Moreover, the paper proposes a formal representation of multimodal inputs using the hybrid approach that combines the attribute multi-set grammar with the linear logic. This paper starts from discussing the main features of a multimodal system and the classes of cooperation between modalities. The attribute multi-set grammar combined with the linear logic enables to highlight the multidimensionality of multimodality and allows to formally describe ambiguities that can occur.

Various organizations use the RFID technology for linking, tracking and identifying objects in their operative context. Nevertheless, the RFID components cannot yet be considered as mobile, intelligent and communicating elements of the organization's information infrastructure. They are not always used for accomplishing the linkage between the physical world and the adopted Information Technologies (IT) solutions. Therefore, they are not used for enabling organizations to automatically monitor, decide, and take actions. Heterogeneous networked devices and services installed within the organizations, often work independently instead of collaborating for offering a better quality of the daily activities to the end-user. This paper discusses the adoption of a Smart Ubiquitous Platform (SUP) for monitoring and managing the documents circulation by using the RFID technology. Advantages of the adoption of RFID are discussed too. [ABSTRACT FROM AUTHOR]

The growth of the Internet and its associated technologies did open space for a new type of human interaction: virtual, social interaction environments.The introduction of regulated interaction in these virtual interaction spaces may be a solution towards their organization and inherent increased credibility. In this paper we propose a model for interaction regulation and control for virtual, social interaction spaces, called Social Theatres. A multi-layer software architecture was developed to support this web-based interaction model, allowing easy construction of such social interaction spaces and adaptation to users' devices. This paper discusses the advantages of regulated interaction, addresses the Social Theatre metaphor and presents the software architecture for the implementation of these regulated social interaction spaces.

In this paper, we propose an identities(ID) based watermarking scheme for Java programs. In our scheme, the watermark is generated by participants’ identities, embedded via the watermarked opaque predicates, and verified using zero-knowledge proof. We also present a construction of a family of opaque predicates by Legendre symbol, which is resilient, cheap, and stealthy. The order of the watermark is encoded and embedded into the watermarked opaque predicates, and the watermarked opaque predicates are treated as threads of a Java program. Thus, the embedded watermark is dynamic and secure against all usual types of watermarks algorithms attacks and watermarks protocols attacks, and also secure against static and dynamic attacks. Keywords: Java programs, watermarked opaque predicates, ID, aggregate signature, watermarking scheme. [ABSTRACT FROM AUTHOR]

With the recent proliferation of documents, automatic metadata extraction from document becomes an important task. In this paper, we propose a novel template matching based method for header metadata extraction form semi-structured documents stored in PDF. In our approach, templates are defined, and the document is considered as strings with format. Templates are used to guide finite state automaton (FSA) to extract header metadata of papers. The testing results indicate that our approach can effectively extract metadata, without any training cost and available to some special situation. This approach can effectively assist the automatic index creation in lots of fields such as digital libraries, information retrieval, and data mining. [ABSTRACT FROM AUTHOR]

Inter-organizational business cooperations can be described from different viewpoints each fulfilling a specific purpose. Since all viewpoints describe the same system they must not contradict each other, thus, must be consistent. Consistency can be checked based on common semantic concepts of the different viewpoints. This is sufficient for equal concepts, while weakly related concepts, e.g. related to runtime behavior of viewpoints, have to be considered explicitly. In this paper we identify dynamic consistency issues correlated to the runtime behavior between value and coordination viewpoints on behalf of an example. In particular, an issue class on occurrence estimations of execution options and an issue class on granularity differences in modelling are identified and illustrated. [ABSTRACT FROM AUTHOR]

In Service-Oriented Architectures (SOAs), software systems are decomposed into independent units, namely services, that interact with one another through message exchanges. To promote reuse and evolvability, these interactions are explicitly described right from the early phases of the development lifecycle. Up to now, emphasis has been placed on capturing structural aspects of service interactions. Gradually though, the description of behavioral dependencies between service interactions is gaining increasing attention as a means to push forward the SOA vision. This paper deals with the description of these behavioral dependencies during the analysis and design phases. The paper outlines a set of requirements that a language for modeling service interactions at this level should fulfill, and proposes a language whose design is driven by these requirements.

This paper discusses the importance of language and culture in the effective design and widespread acceptance of handheld devices in foreign markets. To this end, key challenges that usability experts and interaction designers face while designing foreign language keypads for handheld devices are discussed and analyzed. The discussion presupposes English as the point of reference for design decisions but focuses on the challenges faced when considering foreign language devices. For the context of this paper, Arabic is cited as the ‘foreign' language in the design of BlackBerry devices. [ABSTRACT FROM AUTHOR]

In this paper, we propose a human-robot interface in networked and multi-sensored environments. The human robot interface is an essential part of intelligent robotic system. Through the human robot interface, human being can interact with the robot. Especially, in multi-sensored environment, the human robot interface can be developed with remarkably extended functionality. Generally, handheld device such as PDA is a suitable for human robot interface because of its mobility and network ability. In this paper, we select PDA as device of human robot interface. In the implemented framework, the robot user can monitor what happens in multi-sensored environment and control the mobile robot easily and intuitively. [ABSTRACT FROM AUTHOR]

Industrial safety can be regarded as a major issue of industrial environments nowadays. This is why industries are currently spending huge amounts of resources to improve safety in all levels by reducing risks of causing damages to equipment, human injuries or even fatalities. This paper describes how Virtual Reality, Human Factors and Rule-based technologies are used in the framework of the VIRTHUALIS Integrated Project towards industrial training, safety management and accident investigation. The paper focuses mainly on the VR system specification and basic modules, while at the same time it presents the main system modules that synthesize the tool as a whole. [ABSTRACT FROM AUTHOR]

SystemC is a popular open source library in C++ for developing embedded system design, from the abstract System Level Design until the accurate Register Transfer Level Design. SystemC simulation, however, runs in console mode (text-based), thus making it difficult for user to interact with the simulation. To extend the capabilities of SystemC simulation, it is necessary to create Graphical User Interface. In this paper we recommend to use RapidPLUS tool for making the interface for embedded system prototype to reduce time to market. We also propose the connectivity between RapidPLUS and SystemC by using socket communication that attached in JavaBean RapidPLUS object [ABSTRACT FROM AUTHOR]

Recently, the battery and low-power H/W technologies for mobile and wearable computing devices have been advanced rapidly. But on the other hand the computation and communication demands of the embedded applications are increasing more rapidly. Therefore, the application developers are still required to develop their codes to utilize the available energy as efficient as possible. The provision of software power measurement with reasonable accuracy, consistency and low overhead is an indispensable factor for software power engineering. In this paper, we present a time-triggered mechanism for providing energy consumption profiles in the level of C functions. The similar mechanisms have already been introduced at the previous researches such as PowerScope and ePRO. Instead, we, in this paper, introduce our efforts to extend these researches to incorporate power domains and DVS(Dynamic Voltage Scaling), then interpret these mechanisms as the view of time-triggered approach for better understanding to the relationships among timer interrupt, context switching, DAQ triggering, multi-channel DAQ delay, and etc. From our experimental results, we could conclude that the time-triggered approach for the function level energy measurement properly worked with low overheads and produced consistent energy consumption profiles on the DVS-applied program codes running upon the platforms supporting multiple power domains.

In a pervasive environment, context aware services are necessary to enable collaborate and communicate with others in order to provide proper service to users. Each service can be designed with individual context information which represents different perspective over the context. This paper proposes an advanced context management model with context alignment among heterogeneous context aware services. This model enable the interaction between context information producer devices and context information consumer devices and as well as their insertion in an open environment. And this paper show how this model can be used in context aware middleware. [ABSTRACT FROM AUTHOR]

This paper discusses the mechanical design and simulation of a novel omnidirectional wheel based on Reuleaux-triangles. The main feature of our omniwheel is that the point of contact of the wheel with the floor is always kept at the same distance from the center of rotation by mechanical means. This produces smooth translational movement on a flat surface, even when the profile of the complete wheel assembly has gaps between the passive rollers. The grip of the wheel with the floor is also improved. The design described in this paper is ideal for hard surfaces, and can be scaled to fit small or large vehicles. This is the first design for an omnidirectional wheel without circular profile, yet capable of rolling smoothly on a hard surface. [ABSTRACT FROM AUTHOR]

This paper relates to a method for performing Stateful Packet Inspection(SPI) in real time using a session table management scheme that allows more efficient generation of session state information. SPI is an important technique to reduce false positive alerts in network intrusion detection system(NIDS). As the number of session increases, this technique requires a higher processing speed, thereby causing performance problems. However, existing software-based solutions cannot perform real-time packet inspection ensuring the wire speed. To guarantee both performance and functionality with respect to statefulness, we designed and implemented SPI-based intrusion detection module in a FPGA to help alleviating a bottleneck in network intrusion detection systems in this paper.

With constantly increasing complexity of active measurement methods, the issue of processing measurement results becomes important. Similarly to traditional pattern discovery, temporal patterns found in active measurement samples should be provided effective storage and means to compare to other samples. Traditional time series data mining is not applicable to temporal patterns in active measurement time series. This paper proposes a pattern discovery method based on unique features of active measurement results. The method is implemented in form of a database and is used in the paper to verify the proposed method. [ABSTRACT FROM AUTHOR]

The research on the detection of zero-day network attack and the signature generation is highlighted as an issue according to the outbreak of the new network attack is faster than a prediction. In this paper, we propose a very practical method that detects the executable codes within the network packet payload. It could be used as the key function of the signature generation against the zero-day attack or the high speed anomaly detection. The proposed heuristic method in this paper could be expressed in terms of visually classifying the characteristic of the instruction pattern of executable codes. And then we generalize this by applying the discrete parameter Markov chain. Our experimental study showed that the presented scheme could find all types of executable codes in our experiments.

The nature of the conscious experience of love is a puzzle to people all around the world. Many of us want to understand our love in order to make it more sustainable. An application developed for this purpose is presented in this paper: Rose is a self-evaluation application that aims to help individuals evaluate and understand the many dimensions of their love. Rose is freely available on the Internet. In this paper, we summarize the results of everybody who has taken part in the on-line self-evaluation using this application. [ABSTRACT FROM AUTHOR]

Timely traffic identification is critical in network security monitoring and traffic engineering. Traditional methods using well-known ports, protocols and precise signature matching are no longer accurate with the proliferation of new applications. Recently, applying pattern recognition methods to classify network application traffic based on the flow parameters (e.g. port, flow duration, etc.) has become increasing popular. However, many methods developed in the previous works are either too complex to be applied in real-time, or suffer from lower accuracy due to the insufficient knowledge of the application. In this paper, we first give an overview on the developments of pattern recognition methods as traffic classification tools. We then develop two separate pattern recognition methods: one with supervised learning, and one with un-supervised learning, and apply them to classify traffic captured from a campus backbone network. The supervised learning method (an optimized SVM method) yields approximately 99.41% accuracy for the collected traffic. The un-supervised learning method (an entropy based clustering method) gets the average accuracy of 92.41% for the top 20 traffic generating hosts during the same time period. Performance test on a single PC with 3GHz Pentium 4 processors and 1GB of memory show that both methods can handle more than 10000 network flows per second, close to real time requirements for many situations.
