| Synthetic Environments (SE) facilitate an easy setup of various virtual
realities since they are component-based and relatively easy maintainable.
Through three stages, involving various types of stakeholders, the feasibility
of SEs for cooperative product design (CPD) was explored: 1) Semi-structured
group interviews with 19 engineers and designers assessed SE's potential for
CPD; 2) Implementation of a SE; 3) Comparison of a SE with its real
counterpart, through: a) an experimental task and b) questionnaires to
determine the task performance, the mental workload, the experienced spatial
presence, involvement, and realness. 16 participants had a similar task
performance, mental workload, and involvement but differed in experienced
realism (F(1,30)=5.11, p=.03) and spatial presence (F(1,30)=7.02, p=.01). This
research emphasizes the benefit of SE for CPD, which can increase the
communication, speed and quality of CPD. Hence, a first step is made towards a
new era of CPD. Keywords: Frameworks; reference models; architectures; tools and systems for

| Cooperative Design Using Haptic Interaction and 3D Visualization | | BIBAK | Full-Text | 11-19 | |
| Benoît Otjacques; Marc Krier; Fernand Feltz | |||
| Cooperative design is increasingly used in engineering but this generic term
regroups very diverse approaches and technologies. This paper explores a quite
recent trend aiming to study how multimodality can support cooperative design.
More specifically, a prototype combining 3D visualization and haptic
interaction is described. The potential of this approach is illustrated with
the example of mobile phone design. This research also identifies several
technological questions that must be solved before being able to transfer this
approach to a real industrial context. Keywords: 3D Visualization; Haptic Interaction; Cooperative Design | |||
| "SketSha" -- The Sketch Power to Support Collaborative Design | | BIBAK | Full-Text | 20-27 | |
| Catherine Elsen; Pierre Leclercq | |||
| This paper presents a new supporting tool for distant collaborative design,
named SketSha. This prototype supports the early stages of design and more
particularly the initial and crucial step of free-hand sketching. SketSha and
its particular interface, named the virtual desktop, aim to keep from
Front-To-Front collaborative work all the benefits and to appoint to them some
of the nowadays IT facilities, in order to manage in a realistic and efficient
way a long distance collaboration and to effectively serve the designers'
needs. Our hope is to re-introduce the social aspects and group interactions,
crucial for real system efficacy and adaptation to the business world. The
paper presents the fundamental assumptions made to implement SketSha, that are
questioned and analyzed through a real-size experimentation featuring 30
architecture and building engineering students, working together in real-time
in different locations (Belgium and France). This experiment and the necessary
survey open up interesting fields of investigations, such as the relevance of
the sketch stage and the proposed device to support distant collaborative
design in architecture and the benefit it represents for students, in a
pedagogical point of view, to merge the IT aspects and the design studio. The
methodology and the replicability are analyzed to increase the level and
quality of our students' formation and, finally, a critic of SketSha
constitutes a benefit for the developing teams. Keywords: Distant and Synchronous Collaborative Design; Architecture support device;

| Application of Parallel Programming in Collaborative Design | | BIBAK | Full-Text | 28-35 | |
| Tieming Su; Xiaoliang Tai; Zhixiang Xu | |||
| Aiming at improving the design and assembly efficiency of complex products
in collaborative design, this paper proposes a parallel assembly model which is
based on parallel computing. It divides assembly task into subtasks according
to main branch in the virtual-link structure, and finally the subtasks run in
parallel. This model supports large scale design, improves the speed and at the
same time improves the computing resource utilization of collaborative design
in Grid environment. A collaborative design prototype system based on Grid,
which takes hybrid CSG/B-Rep model as geometric kernel, is developed to realize
parallel assembly. Experimental results obtained from Lenovo DeepComp 1800
System are displayed and analyzed. Keywords: Collaborative design; parallel computing; virtual assembly; Grid | |||
| Collaborative Explorative Data Analysis Applied in HTML | | BIBAK | Full-Text | 36-44 | |
| Mikael Jern | |||
| This paper introduces a Visual Analytics framework for the support of
collaborative explorative data analysis (EDA) based on task-relevant
visualization components embedded in HTML documents. The goal of our research
is to let the analyst visually explore and search the answers to various
questions about data and simultaneously capture and save important discoveries
and thus enable collaboration and sharing of gained insights and knowledge to
remotely dispersed team members over the Internet. A team will benefit from an
interactive collaborative instrument that can "coach" them in the understanding
and testing of hypotheses leading to faster understanding and a higher
confidence level in the visual information. The foundation for this approach is
based on the publicly available GeoAnalytics visualization framework and class
library (GAV). Keywords: Visual analytics; collaboration; explorative data analysis; HTML | |||
| Cooperative Visualization of Privacy Risks | | BIBAK | Full-Text | 45-53 | |
| George O. M. Yee; Larry Korba; Ronggong Song | |||
| The growth of the Internet has been accompanied by the growth of e-services
(e.g. e-commerce, e-health). This proliferation of e-services has put large
quantities of customer private information in the hands of service providers,
who in many cases have mishandled the information to the detriment of customer
privacy. As a result, government bodies have put in place privacy legislation
that spells out the privacy rights of customers and how their private
information is to be handled. Service providers are required to comply with
this privacy legislation. This paper proposes a cooperative visualization
technique that can be employed by service providers to understand how private
information flows within their organizations, as a way of identifying privacy
risks or vulnerabilities that can lead to violations of privacy legislation.
The description of the technique includes a model of how an e-service uses
private information, a graphical notation for the visualization, and an
application example. Keywords: Cooperative visualization; privacy risks; privacy legislation; privacy

| An Ontology-Based Semantic Cooperation Framework for Business Processes | | BIBAK | Full-Text | 54-57 | |
| Yue Ni; Shuangxi Huang; Yushun Fan | |||
| Nowadays many functions within intra- and inter-enterprises have been
encapsulated into Web services to enable platform independent integration and
interoperation. To realize the enterprise applications, most Web services are
composed as workflows based on Business Process Execute Language (BPEL).
However, the absence of semantic information in processes reduces the
efficiency of interoperation and cooperation among these Web services from
different providers. In this paper, a novel framework to support semantic
cooperation of business processes is proposed, which brings semantic
information into processes through mapping OWL-S to BPEL and Web Service
Definition Language (WSDL) documents, then Web services from various domains
and enterprises can understand each other eventually. The framework is being
implemented under Project ImportNET. Keywords: ontology; semantic; cooperation; BPEL | |||
| A Framework for Tolerance Analysis in Collaborative Engineering Mechanical Design | | BIBAK | Full-Text | 58-65 | |
| Carles Riba Romeva; Roberto Pérez; A Luis W. Hernández-G.; A Joaquim Ciurana-G. | |||
| Nowadays, the global competitive environment has a special impact on small
and medium enterprises (SMEs). The development of computer and network
technology has provided opportunities for researchers to construct and build
systems to support collaborative engineering design in a concurrent manner. A
special issue related to the development of design tools to improve the quality
and productivity is the tolerance analysis evaluation through the lifecycle of
the product. In response to this context, the tools should be collaborative and
flexible. This paper shows the development of a framework to concurrent
tolerance analysis evaluation through the lifecycle of the product in
collaborative engineering mechanical design. Keywords: Collaborative Engineering; Tolerance; Analysis; Mechanical Design | |||

collaboration over XML documents where users can work off-line on their
document replica and synchronise in an ad-hoc manner with other users. Our
algorithm for maintaining consistency over XML documents recursively applies
the tombstone operational transformation approach over the document levels. Keywords: XML; collaborative editing; peer-to-peer collaboration; operational

| Cooperative Scenario Building in Environmental Planning: Agents, Roles, Architectures | | BIBAK | Full-Text | 74-83 | |
| Domenico Camarda | |||
| The new complexity of planning knowledge implies innovation of planning
methods, in both substance and procedure. In this concern, an increasing number
of experiences on multi-agent interactions is today located within processes of
spatial and environmental planning. Case studies have not been deliberately set
up using formalized and/or predefined multi-agent-system layouts. Therefore, a
multi-agent approach and supporting system (MAS) emerged in a bottom-up
fashion, driven by the needs demanded by the activities carried out. However,
such approaches have not been formalized properly to date. The present paper
aims at scanning experiences on the setting up of cooperative multi-agent
systems, in order to investigate the potentials of that approach on the
interaction of the agents in planning processes. Keywords: Multi-agent interaction; Environmental planning; Cooperative

| Towards a Platform for Cooperative Creation of Scientific Publications | | BIBAK | Full-Text | 84-88 | |
| Guilherme Saraiva; Orlando Carvalho; Benjamim Fonseca; Hugo Paredes | |||
| Writing scientific publications is usually a challenging and complex
activity, involving several authors. Despite the different natures of their
contributions, this activity is clearly collaborative and the collaboration is
usually achieved through face-to-face meetings and using email to exchange the
documents. More recently the availability of collaborative editors introduced a
further step in the collaboration, but none of the existing solutions
contemplate some specific issues like referencing and publishing adequately.
This fact motivated us to conduct a study to evaluate the requirements for a
platform that integrates in a single solution the three main functionalities
required: a text editor, a reference manager and a connector to scientific
digital repositories. Keywords: Cooperative applications (CA); Group Editors; Scientific Digital

| As contemporary intelligent transportation systems are becoming a reality in
our everyday's life and future urban transportation brings about concerns of a
wide range of new performance measures, multidisciplinary teams are more and
more faced with the need to work collaboratively so as to meet those demands.
This paper reports on the specification of the MAS-T2er Lab framework,
emphasising on its ability to support collaborative simulation and different
perspective analyses of the complex and dynamic application domain of traffic
and transportation in major urban areas. The architecture underlying all
subsystems within the framework is discussed on the basis of the multi-agent
systems metaphor, and a practical overview of its use is presented. Keywords: Cooperative simulation; visualisation for multiple users; cooperative

| A Collaborative Model for Wireless Sensor Networks Applied to Museums' Environmental Monitoring | | BIBAK | Full-Text | 107-116 | |
| Lina M. Pestana Leão de Brito; Laura Margarita Rodríguez Peralta | |||
| The major functions of the Wireless Sensor Networks (WSNs) cannot be
accomplished without collaboration among sensor nodes. However, most of the
work found in literature only focuses on a specific type of collaboration,
associated with the accomplishment of a certain task, such as: sensing, signal
processing, computing, routing, etc. In this paper, we present a graph-based
model of collaborative work for WSNs. This model is called Wireless Sensor
Networks Supported Cooperative Work (WSNSCW) and was created for the specific
case of WSNs. We also present the formalization of some of the entities of the
model and of its properties. This is a generic model that is being used as a
basis for the development of a 3D web-based awareness tool for WSNs. In this
paper, the model is applied to the specific case of a WSN created in a museum
for artwork conservation. Keywords: Awareness tool; CSCW; Graph-based Model; Museums' environmental monitoring;

| Mixed Reality-Mediated Collaborative Design System: Concept, Prototype, and Experimentation | | BIBAK | Full-Text | 117-124 | |
| Rui Wang; Xiangyu Wang | |||
| This paper introduces a Mixed Reality-mediated Collaborative design system,
named MR-Collab, which combines Mixed Reality (MR), Augmented Reality (AR) and
various channels of communication technologies. The concept and system of
MR-Collab are developed based on the Benford's Mixed-Reality boundaries theory.
This paper presents how this theory is used as a tool to analyze the system
framework and guide the design of the MR-Collab system. The technique details
of prototype and application scenario of this system are also elaborated in the
paper. The system, MR-Collab, is designed in the purpose of facilitating
collaboration between distributed users through the Mixed Reality environment.
Experimentation that can measure the correlations between the design
performance/behaviors with the increased degree of co-presence is also planned
in this paper. Keywords: Cooperative design; cooperative visualization; concurrent visualization;

| Decomposition of Information for Plant Collaborative Design and Set-Up | | BIBAK | Full-Text | 125-132 | |
| Dariusz Choinski; Mieczyslaw Metzger; Witold Nocon | |||
| A problem of coordinating engineers working in different fields during
design and control of an industrial installation is especially difficult during
start up and modification of the process. Any work carried out in such a case
must be coordinated in real time. Moreover, level of access to information is
differentiated for different branches of engineers. In this work a hybrid
agent-based system for cooperative plant design and set up of the
biotechnological pilot plant is proposed. The major contribution deals with
decomposition of biotechnological plant information by hybrid agent system for
enhancing cooperation of experts having different knowledge about the process.
Hybridization of the process is performed considering nine states, while
estimation of the information distance is performed based on partial
Kullback-Liebler cross-entropy function. Experience gained during design and
exploitation of the mentioned biotechnological pilot-plant suggests this
solution to be promising. Keywords: Collaborative design and set-up; expert cooperation; hybrid agent-based

| As Workplaces are being equipped with communication-oriented software more
and more people are faced with the need to handle with multiple communication
contexts in environments with ever increasing multi-tasking nature. The
increased complexity of managing communication in different contexts is
becoming more demanding than ever before. This paper presents a unified
collaborative system named ActivePlace, which enables context-awareness in
communication and collaboration. In this paper we discuss the new design we
applied compared to the traditional online room-based workplace systems, such
as use of context-aware extended presence and the concept of activity awareness
for places. The ActivePlace provides an infrastructure for communication and
collaboration in a context-sensitive basis. Keywords: Collaboration applications; multi-tasking; unified collaborative

| With the growing use of computers and the Internet, it has become difficult
for organizations to locate and effectively manage sensitive personally
identifiable information (PII). This problem becomes even more evident in
collaborative computing environments. PII may be hidden anywhere within the
file system of a computer. As well, in the course of different activities, via
collaboration or not, personally identifiable information may migrate from
computer to computer. This makes meeting the organizational privacy
requirements all the more complex. Our particular interest is to develop
technology that would automatically discover workflow across organizational
collaborators that would include private data. Since in this context, it is
important to understand where and when the private data is discovered, in this
paper, we focus on PII discovery, i.e. automatically identifying private data
existant in semi-structured and unstructured (free text) documents. The first
part of the process involves identifying PII via named entity recognition. The
second part determines relationships between those entities based upon a
supervised machine learning method. We present test results of our methods
using publicly-available data generated from different collaborative activities
to provide an assessment of scalability in cooperative computing environment. Keywords: Collaborative computing; privacy; compliance; text mining; machine learning;

| Cooperative Multisite Production Re-scheduling | | BIBAK | Full-Text | 156-163 | |
| Jaime Lloret; José Pedro García-Sabater; Juan A. Marin-Garcia | |||
| One of the main issues in cooperative enterprise planning and scheduling is
how to re-assign tasks without involving too many components of every
enterprise and implying too many changes in the whole system. We propose a new
system that is able to re-schedule tasks in cooperative multisite production
automatically avoiding one of the main problems that have schedule programmers
that are in charge of two or more cooperative enterprises. The system is based
on making virtual groups of machines that perform the same tasks and
establishes links between machines from different groups. We will describe the
algorithm in detail and we will validate it using a case of study. Results show
that our proposal gives better performance. Keywords: Scheduling; Cooperative decision making; Supply chain;

| Collaborative simulation conduces to the efficiency improvement of complex
product design. Modeling, especially visualization modeling, is among the most
important steps in building a collaborative simulation system. Applying Unified
Modeling Language (UML) to High Level Architecture (HLA)-based collaborative
simulation system will lead to a better visualization, understanding, design
and construction of the system. A UML Profile for HLA-based collaborative
system modeling (UML-HLA) was proposed to extend UML on the basis of
HLA-specific characteristics. Firstly, we presented the overall structure of
UML-HLA, and then the stereotypes, tagged value and theirs constraints in
UML-HLA were introduced. Using UML-HLA may model HLA-based collaborative
simulation system visually, precisely and effectively. Keywords: UML profile; high level architecture; collaborative simulation;

| 3D Reconstruction of Large Scale City Models as a Support to Sustainable Development | | BIBAK | Full-Text | 172-175 | |
| Jean-Philippe Pons; Souheil Soubra | |||
| No part of the economic community can now escape from the urgent issues
related to global warming, carbon footprint and reducing energy consumption.
Nevertheless, the construction sector is particularly under pressure. Indeed,
it is one of the biggest consumers of energy. It also largely contributes to
the massive use of some critical resources (such as energy, water, materials
and space...) and is responsible for a large portion of greenhouse gas
emissions. In that context, the paper explores new approaches for urban
planning by combining Virtual Environments and Simulations to address
sustainability issues. These approaches are based on the possibilities of
reconstructing 3D models of the built environment using standard photographs
taken with off-the shelf hand-held digital cameras. The 3D models can then be
combined with simulations in order to address sustainable urban development
issues. Keywords: Total life cycle support; 3D virtual world environments | |||

| The Application of Stochastic Dominance to Sensitivity Analysis in Quantitative Multiple Criteria Decision Making (MCDM-1) | | BIBAK | Full-Text | 184-191 | |
| Leonas Ustinovichius; Ruta Simanaviciene | |||
| The paper considers sensitivity of multicriteria decision making methods
based on quantitative measurements and their use in determining effective
construction investment projects. The problem of effective construction
investments is of paramount importance for a group of people (experts) making a
cooperative decision because these investments determine the potential of
construction and the structure of expenses. Similar problems also arise in
other fields of engineering. The calculation of investments is an expensive
tool of enterprise management used in planning the investments. The paper
describes the main principles of sensitivity analysis of the initial data, i.e.
the significances of the criteria elicited from the survey of experts using
quantitative multiple criteria decision methods. Monte Carlo method as well as
a particular form of stochastic dominance are also applied and the algorithm
and a case study demonstrating the application of the suggested technique are
presented. Keywords: Cooperative decision making; quantitative methods; Monte Carlo method;

| The standardization of eLearning environments and the design of
collaboration scripts are two research areas that are acquiring a greater
attention within the Computer Supported Collaborative Learning (CSCL)
community. IMS Learning Design (IMS-LD) is the specification used to describe
instructional strategies. In this paper we analyse the suitability and lacks of
IMS-LD for modelling collaborative learning processes. Based on this result, we
propose a reference model inside the IMS specifications core and the use of a
graphical notation called CIAN (Collaborative Interactive Applications
Notation) as CSCL scripting language. Using these specifications of a high
level of abstraction and mappable to a computer-interpretable notation such as
IMS-LD, allows hiding the particularities of the standard to instructional
designers. Keywords: Learning design; CSCL; methodological approach; model-driven development | |||

| Cooperative, Cross-Discipline Teaching and Learning | | BIBAK | Full-Text | 216-224 | |
| Vasilije Kokotovich | |||
| This paper will discuss the outcomes and findings of a cross-discipline
research experiment, which was a pilot study aimed at developing
cross-discipline teaching modules within science and industrial design. A
central aim was to develop teaching techniques that would equip science
students with creative conceptualisation skills and strategies that lead to
innovation in science, and provided industrial design students with insights
into next-generation nano-technologies that can be explored and used as
components within innovative artefacts. Early results suggest that there was a
positive effect in the development and enhancement of cross-disciplinary
teaching modules. Cross-discipline cooperative lectures and practical sessions
were developed and tested on focus groups of science students and industrial
design students. Video-taped data of the study provided feedback. This data was
critically analysed. This valuable data/feedback informs new cross-disciplinary
teaching methodologies and strategies. Analysis of the student comments
revealed that both groups of students highly valued the new learning
experiences. It is argued that working cooperatively and jointly in the
co-development of cross-faculty teaching initiatives will improve the quality
of teaching, via interactions that introduce and develop alternative teaching
practices. While cooperative design may well refer to a cooperative set of
designers within the same general disciplines, this example extends the view to
demonstrate the importance of cooperative practices between disciplines. Keywords: Cooperative application; Cooperative Design; Cooperative Learning | |||

| Applying Web 2.0 Design Principles in the Design of Cooperative Applications | | BIBAK | Full-Text | 229-236 | |
| Niels Pinkwart | |||
| "Web 2.0" is a term frequently mentioned in media -- apparently,
applications such as Wikipedia, Social Network Services, Online Shops with
integrated recommender systems, or Sharing Services like flickr, all of which
rely on user's activities, contributions, and interactions as a central factor,
are fascinating for the general public. This leads to a success of these
systems that seemingly exceeds the impact of most "traditional" groupware
applications that have emerged from CSCW research. This paper discusses
differences and similarities between novel Web 2.0 tools and more traditional
CSCW application in terms of technologies, system design and success factors.
Based on this analysis, the design of the cooperative learning application
LARGO is presented to illustrate how Web 2.0 success factors can be considered
for the design of cooperative environments. Keywords: Social Software; Cooperative Applications; CSCW; CSCL | |||

architecture can take full advantage of grid features such as computing
capability, massive data storage and device sharing etc., which is more
suitable for the development of a complex collaborative design environment
compared with the widely used Distributed Component Object and existing Grid
based collaborative design architectures. Under this architecture, the
construction method of Grid services is researched. Parallel and distributed
Grid computing technology is used to increase the efficiency of complex product
design. A collaborative modeling method based on XML is put forward to support
real-time modeling by using design semantics instead of 3D solid model data
transport. Finally, a collaborative design prototype system based on Globus
Toolkit 4.0 is presented and analyzed. Keywords: Grid; collaborative design; parallel computing; CAD | |||

product or service. This user research information provides crucial sources of
research insights, which lead to a process of finding ideas about
functionality, features, criteria, and design attributes of a product or
service. Usability testing is also considered as a part of the user research
process to verify the feasibility of the design. The proposed Capturing,
Sharing, and Connecting User Research (CSCUR) tool can help the design
researcher to record and utilize user data efficiently. CSCUR tool provides a
keyword list and procedure used as a guideline for design researchers to
investigate related issues that need to be considered in design process,
leading to an innovative design and responding to users' needs. Searching
functionality facilitates activities in exchanging ideas and encouraging
teamwork among the design research community. Keywords: Collaborative Design Research Tool; Design Research Database | |||
| Cooperative Internet-Based Experimentation on Semi-industrial Pilot Plants | | BIBAK | Full-Text | 265-272 | |
| Mieczyslaw Metzger; Grzegorz Polaków | |||
| In this work a framework for cooperative experimentation with
semi-industrial pilot plants is presented. A software solution designed to
support multi-user cooperative experimentation is described, along with the
supporting hardware, which was specifically designed for the task. A structure
of dual networking is proposed, with horizontal real-time protocol for hardware
integration and vertical multi-user access points for human interaction. To
avoid potential conflicts between users, prioritisation is performed, as
resources available (time, hardware, and data) are limited. An important
sub-problem is described in details, i.e. large groups of students splitting
into smaller subgroups, collaboratively performing partial experiments in order
to achieve solution of problem stated by an instructor. Work and data flows
have to be carefully designed to keep control of the collaboration an example
of such schedule is provided and described. Keywords: Collaborative working environment; multiple user system; agent based
cooperation; remote learning; distributed control system | |||
| Cooperative User-Centric Digital Identity Management Framework for Public Web Portals | | BIBAK | Full-Text | 273-276 | |
| Sylvia B. Encheva; Sharil Tumin | |||
| This work focuses on control of users' access to public Web portals. A
lightweight Web-based application framework is proposed for sharing users' data
among federated organizations. A user receives an access-card after a
subscription to a portal. The card is used as an identifier to the federated
organizations' portal. Keywords: Digital identity; cooperative management; Web portals access control | |||
| Architecture Modelling of Large Cooperative Environments | | BIBAK | Full-Text | 277-280 | |
| Martin Ota; Ivan Jelínek | |||
| The article is focused on the architecture of large cooperative ICT
environments. The logical levels are the most important feature in the
architecture. The paper introduces a system of three logical levels: the
business architecture level, the application architecture level and the
physical architecture level. Each level can contain several views -- either
complete or partial views. Each level can have more than one instance. It
provides a seamless platform for modelling how the business processes of
collaborative engineering are running onto the architecture. UML is used as the
modelling language. The instructions on how to use it are presented in the
paper. Keywords: Collaborative processes; ICT architecture; modelling; UML | |||
| Cooperative Design Workflows for Multiphysics Applications | | BIBAK | Full-Text | 281-285 | |
| Toàn Nguyên; Jean-Antoine Désidéri | |||
| This paper is devoted to the distributed workflows as a means to support
large simulation applications, such as aircraft in flight dynamics. We are
interested in the description of physics, their modeling in adequate tools,
implementation and their deployment and execution on wide-area networks. This
requires a layer where application codes are deployed and must be run
cooperatively in distributed and parallel environments. We advocate the use of
distributed and composite workflows in order to achieve effective and seamless
large-scale simulation. Keywords: Cooperative Design; Workflows; Multiphysics Design | |||
| Cooperative Security Schemes for Mobile Ad-Hoc Networks | | BIBAK | Full-Text | 286-294 | |
| Pino Caballero-Gil; Candelaria Hernández-Goya | |||
| The existence of selfish nodes, who do not cooperate in routing and
forwarding, is one of the most critical problems for the applicability of
Mobile Ad-hoc NETworks (MANETs). In this paper we propose several novel
currency-based methods for stimulating cooperation among nodes of a MANET. In
particular, the proposed protocols allow improving different aspects of
previous schemes based on virtual currency thanks to the incorporation of the
concept of credit that will allow broke nodes to use the network while they
have not a selfish behaviour. A complete analysis of simulations leads to
several conclusions that establish the improvement of the proposal with respect
to previous schemes. Keywords: Cooperation; ad-hoc networks; security | |||

| Towards a Cooperative Visual Authoring Environment for Storytelling | | BIBAK | Full-Text | 299-306 | |
| Ivan Blecic; Arnaldo Cecchini; Giuseppe A. Trunfio | |||
| In this paper we present a methodological approach and a client-server
software authoring environment for cooperative visual creation of
story-outlines. The methodological approach adopted for story outlining
facilitates the representation and visualisation of relevant aspects of stories
in a way that is easy to use and understand, and enough general to admit a
large number of types and genres of stories. Additional design objectives were
set in order to support effective cooperative work and rapid story prototyping. Keywords: Storytelling; cooperative story-outlines; visual cooperation; multiple user

| Cluster Computing in Drug Logistic Monitoring and Management | | BIBAK | Full-Text | 307-310 | |
| Guofeng Qin; Qiyan Li; Xiuying Deng | |||
| We applied the cluster computing as a key technology for a drug logistic
information system that we developed. In order to improve the dependability,
scalability, and other QoS features of the server cluster, resource dynamic
dispatching, task distribution, and workflow controlling were among the key
issues that we focused in our development. Keywords: Cluster computing; cooperative computing; concurrent processing; logistic
