| Concert Halls in Cooperative Virtual Environments | | BIBAK | Full-Text | 1-6 | |
| A. Benjamin Spaeth | |||
| The integration of simulation tools into an architectural design and
decision process comprise a large potential. The design of acoustic spaces like
concert halls or theatres is very complex in regard to the design and
evaluation of its acoustic quality. To enable evaluation and discussion between
different participants of an acoustic design and decision process an adequate
cooperative and interactive design environment was searched. As the acceptance
and the reliability of cooperative virtual environment rises with the number of
addressed senses and the quality of representation the combination of a high
quality visual simulation (COVISE/COVER) with a high quality acoustic
simulation (RAVEN/VA) is achieved. The paper describes the system architecture
in regard to its cooperative aspects and points out possible cooperation modes.
Different application scenarios of the virtual acoustic environment, like
education scenario or planning scenario are described through case studies. The
experiences from these scenarios are summarised in the conclusions. Keywords: virtual acoustics; virtual reality; architectural design; design tools | |||
| Design Offered Up: Control and Open Outcomes in a Digitally Enabled Design Process | | BIBAK | Full-Text | 7-13 | |
| Anne Filson; Gary Rohrbacher | |||
| This paper presents the design of a digitally fabricated, customizable line
of furniture and casework objects that leverage parametric technology and
social networking to produce a highly collaborative distributed digital
fabrication workflow. It describes how a furniture system, serving as an
apprehensible model for architecture, was designed concurrently with the
networked, multi-agent workflow that manufactures it and the layered user input
that defines it. The furniture object designs are inextricably linked to their
fabrication by a distributed network of small fabricators that supplant the
single large manufacturer, and to their open outcomes that balance professional
design expertise with user input. The paper concludes with describing how this
model challenges the architectural profession's prevailing focus on the
transactional and object oriented capabilities of recent digital innovations.
By using such tools to design the objects within their systemic and networked
relationships, architects might successfully create outcomes that better
respond to society's increasingly complex demands. Keywords: Collaborative Design; Emergence; Network Theory; Parametric Modeling; Open

| Design Interaction via Multi-touch | | BIBAK | Full-Text | 14-21 | |
| Marc Aurel Schnabel; Rui (Irene) Chen | |||
| We present a multi-touch-tabletop tool for design-collaborations and
-communication tasks employing three-dimensional digitalized models. Our system
allows users from various disciplines to communicate and share their ideas by
manipulating the reference and their own input simultaneously by simply using
intuitive gestures. Haptic and proprioceptive perception of tangible
representations are perceived and understood more readily whereby our system
provides an increased potential to compensate for the low spatial cognition of
its users. Our integration of combining both model-based and participatory
approaches with multi-touch tabletop system setups differs considerably from
conventional visual representations for collaborative design. Since the
multi-touch design interaction allows users to engage intuitively within
virtual design environments, it is presenting a next generation of common
graphical user interfaces. Keywords: Multi-touch; collaboration; interaction; haptic; design | |||

| Today, typical classrooms are still equipped with blackboards, chalk and
sometimes overhead projectors. Technology-enriched rooms can often only be
found in school libraries or computer pools where students can research topics
on the WWW or use other specific computer applications. In this paper, we
present an educational game called "Parcours", developed for the interactive
SMART table. This cooperative design game, installed on a tabletop that is
located within a classroom, is intended to teach primary school children
collaboration and coordination skills as well as logical thinking. Keywords: Collaborative Learning; Cooperative Design; Multitouch table | |||

| Simulation of Collaborative Innovation System in Cluster Environment | | BIBAK | Full-Text | 37-44 | |
| Shuangxi Huang; Hua Bai; Jinsong Bao; Aidan Li | |||
| Cluster innovation system (CIS) is a kind of complex adaptive system. The
system performance of CIS depends critically on the interactions between its
parts. Because it is hard to formalize and define the system equation, the
analytical or deductive method is unfitted with the high dynamics, uncertainty,
and complex structure of CIS. In the paper, swarm principles are used to deal
with the complexity of CIS. The multi-agent model is established to represent
the interaction, collaboration, group behavior, and the emergence of higher
order system structure. Based on this multi-agent model, the emergent behaviors
and the key characteristics of the system are obtained using swarm simulation.
The key parameters for system evolution can be identified and the attribute
features and behavior rules of an individual enterprise (agent) can be set up.
The objective of the research is to find out the key factors influencing the
evolution of CIS and the proper innovation strategy for CIS. Keywords: Cluster Innovation System; Swarm Simulation; Multi-agent | |||
| Implementation of a RIA Tool for Supporting a Collaborative Initiative of Software Process Improvement | | BIBAK | Full-Text | 45-52 | |
| I. Garcia; C. Pacheco; D. Cruz | |||
| Under a Software Process Improvement (SPI) environment, all phases of a
process improvement initiative involving establishing commitment, assessment or
diagnosing, improvement plans generation, pilot implementation and improvements
deployment, may be accomplished collaboratively by different groups inside an
enterprise. Organizational, technical and process-based circumstances have an
impact on process assessment and modeling practices. Based on a Model-based
Collaborative Design, a strategy for collaborative process assessment and
modeling is proposed. This collaborative support helps project managers in
overcoming complexities and to create a common understanding of the process and
products of a SPI initiative. Finally, a Rich Internet Application (RIA) is
developed and applied to provide strong support for distributed project
managers, to collaboratively assess and model their software process within a
SPI project, the CEForSPI (Collaborative Environment For Software Process
Improvement) prototype. This tool represents a collaborative strategy to
support SPI teams in handling the different phases of a typical SPI lifecycle. Keywords: Collaborative model; software process improvement; process modeling; process

based on a time-driven wireless sensor and actuator network. The description
highlights the architectural and cooperative aspects of the proposed system, as
well as key design issues related with the deployment of nodes and the
construction of a data-gathering tree that optimizes system lifetime and

| Taking Cooperative Decisions in Group-Based Wireless Sensor Networks | | BIBAK | Full-Text | 61-65 | |
| Miguel Garcia; Jaime Lloret; Sandra Sendra; Joel J. P. C. Rodrigues | |||
| Several studies have demonstrated that communications are more efficient
when cooperative group-based architectures are used in wireless sensor networks
(WSN). This type of architecture allows increasing sensor nodes' lifetime by
decreasing the number of messages in network. But, the main gap is to know how
to take cooperative decisions in order to make the right communication. In this
paper, we analyze the main aspects related to collaborative decisions in WSNs.
A mathematical analysis will be presented in order to take the correct
decision. Finally, the simulations will show the efficiency of the method used
to make cooperative decisions in WSNs. Keywords: cooperative decisions; cooperative WSN; group-based WSN | |||
| Cooperative Operating Control for Induction or Elimination of Self-sustained Oscillations in CSTB | | BIBAK | Full-Text | 66-73 | |
| Piotr Skupin; Mieczyslaw Metzger | |||
| The problem of cooperative control is especially important in the case of
selection of an appropriate mode of operation for a wide class of bioprocesses.
In classical approach, this can be achieved via SCADA systems used by process
operators. However, due to the nonlinear nature of bioprocesses, the operators
usually are not able to assess the efficiency of a bioprocess, especially in
the presence of self-sustained oscillations (SSO) of the biomass concentration.
Hence, they must cooperate with experts who are usually geographically
dispersed. This paper presents the solution of the above-stated problems using
an additional server application in the layer of supervisory control. The main
tasks of the application are to provide the process data (collected by the
SCADA system) to a group of experts and allow them to discuss possibilities of
enhancing the efficiency of the bioprocess. The taken decisions are then sent
to the operator. Keywords: cooperative operating control; agent-based cooperation; self-sustained
oscillations | |||

| The success of the deployment of decision support systems heavily relies on
the design of knowledge bases. In particular, assessing the quality of
instanced data helps ensure an appropriate use of the knowledge. We present a
collaborative editor for procedural knowledge that manages specific information
about the quality of the data called into the procedures. Experimentations by a
panel of users notably show that information being correctly interpreted and
necessary to draw optimal procedures. Keywords: Data quality; Knowledge models; Decision support | |||
| Adapting Decision Support to Business Requirements through Data Interpretation | | BIBAK | Full-Text | 82-85 | |
| Thomas Tamisier; Olivier Parisot; Yoann Didry; Jérôme Wax; Fernand Feltz | |||
| Decision support shows often a gap between the problems in terms of business
knowledge and the answers restricted to a final decision result. We present a
decisional framework for automating business procedures, developed through with
the administration, that allows managing and formalizing extra information
besides the mere decisional knowledge. This information can be useful to tune
the knowledge model according to operational data, or to better exploit the
decision result in the subsequent stages of a collaborative workflow. Keywords: Decision support; Data interpretation; Information retrieval | |||
| Multilayer Automated Methods for the System Integration | | BIBAK | Full-Text | 86-93 | |
| Dariusz Choinski; Michal Senik | |||
| Large distributed control systems present non trivial problems during
integration. In order to successfully perform integration, MAS methodology has
been widely incorporated. Multiple, distributed over the network, types of
server objects can be treated as a good example of such dynamic systems. This
paper describes multiple user cooperation problems during large system
integration. The introduced MAS forms a top level interaction layer over the
existing system which is composite of hierarchically organized internal sub
layers. Each layer consists of multiple interacting agents which are
indivisible functional entities that can form larger cooperating subsystems
inside their parent layer. Concurrent user cooperation over the integrated
system is performed by means of top level MAS layer which provides indirect
access to all system resources possibly by the graphical interface. Concurrent
user cooperation is possible through multiple agent interfaces and because
agents are created in both Java and .Net no real obstacle currently exists.
Possible user conflicts are solved in the real time automatically by the
internal MAS system mechanisms because all system agents are independent to
some extent. Keywords: JADE; FIPA; OPC; Java; .Net; Multi-Agent Systems | |||
| Active Citizenship in the Planning Process: Information Management vs. Creative Participation | | BIBAK | Full-Text | 94-101 | |
| Ursula Kirschner | |||
| The significance of early and continuous involvement of the citizens in city
development processes is clearly evident in the current critical reporting on
Stuttgart 21 in Germany, a traffic and urban development project to relocate
the Stuttgart railway junction. Stuttgart 21, a planning process for a new
major train station that has gone on for over ten years, has been accompanied
by a citizen protest movement across all party lines since 2009. Construction
has been halted several times.
When citizens are consulted too late, not at all or only intermittently during the development process, the results are often the most varied protests and demonstrations. This research project analyzes methods of citizen involvement in construction planning processes in Hamburg and attempts to identify new approaches to qualitative social research as expert research actions in function of deep drilling. The aim is the development and testing of a new methodology for active citizenship in terms of an expert research like deep drilling instead of working under the involvement of the majority.

| A "Live" Interactive Tagging Interface for Collaborative Learning | | BIBAK | Full-Text | 102-109 | |
| Yang Ting Shen; Tay-Sheng Jeng; Yen-Chia Hsu | |||
| We present a real-time interactive tagging system called SynTag for
collaborative learning in lectures. The system allows students accessing the
web-based interface to tag an ongoing lecture. The collective tagging outcomes
are instantly visualized with a dynamic timeline chart to illustrate the
assessment of all students. With SynTag, students not only engage in a lecture
by the interactive tagging function, but also cooperate with each other to
contextualize the lecture. According to the outcomes of students' collaborative
tagging activities, the critical spatio-temporal segments of a lecture video
are automatically generated as the wave-shape timeline chart. Through the peaks
of the wave-shape timeline chart, the valuable video chips of the lecture can
be easily highlighted and recognized. In the end of this paper, we demonstrate
how the SynTag system contributes to the collaborative learning in
undergraduate classes through quantitative and qualitative studies. Finally, we
conclude with a discussion based on our evaluation for the improvements and
potentials of our system in future works. Keywords: Collaborative learning; Collaborative tagging; synchronous; Timeline;

| Extended Ontology-Based Process Management Architecture | | BIBAK | Full-Text | 114-120 | |
| Tingting Liu; Huifen Wang; Linyan Liu | |||
| Process management is a technology used to design, enact, control, and
analyze business processes. Today although workflow management systems are
readily available and a large number of literatures present improvements in
business process management, the reuse ratio of knowledge involved in process
is low and most of organizations cannot reuse existing knowledge effectively.
In this paper we propose an extended ontology-based process management
architecture. Through analyzing the process characters, we identify six
ontologies in the process management, including process ontology, organization
ontology, resource ontology, knowledge ontology, object ontology and constraint
ontology. OWL language has been used to describe each element in the ontology.
Based on these six ontologies, a four-level process management architecture is
presented and described in detail to show how it can work to reuse the
context-related knowledge in process execution. The main contribution of this
paper is to achieve knowledge reuse in process management. Keywords: process management; ontology; knowledge reuse | |||

| RFID Supported Cooperation for Construction Waste Management | | BIBAK | Full-Text | 125-128 | |
| Jack C. P. Cheng; Lauren Y. H. Ma | |||
| The severity of construction and demolition waste problem has been observed
around the world in recent years. Therefore, management of construction waste
is important worldwide. Currently, radio frequency identification (RFID)
technology is a growing technology which has been applied in many areas
including the construction industry. This paper discusses the application of
RFID technology for construction waste management, which is lacking in research
in the construction industry. This paper presents a proposed RFID-based
approach to facilitate the cooperation among on-site contractors, pick-up truck
companies, and recycling companies. Waste pick-up and recycling could therefore
be enhanced. Some reusable construction wastes like high strength cables are
valuable and prone to be stolen. The proposed system could help the inspection
of these construction wastes by using the automatic tracking capability of RFID
technology. Keywords: RFID technology; construction waste management; waste recycling; pick-up

| Planning for the Environmental Quality of Urban Microclimate: A Multiagent-Based Approach | | BIBAK | Full-Text | 129-136 | |
| Dino Borri; Domenico Camarda | |||
| An increasing concern about urban environmental quality has grown in the
last decades caused by urban production mechanisms. Now, policies and ICT
models need to integrate traditional quantitative techniques with more complex
multiagent tools to support effective recovery strategies.
Basing on a hybrid scenario approach, the present research links information and knowledge aspects to define sequences of events and processes for decisionmaking. An ICT-based model is set up, involving human agents, low-profile artificial (routinary) agents and/or high profile (intelligent) agents, as defined by computer-science and multi-agent studies. Particularly, the paper focuses on the case study of Bari, Italy, addressing multi-agent-based relationships between urban microclimatic and social characters.

| Improving Collaboration in the Construction Industry through Context-Aware Web Services | | BIBAK | Full-Text | 141-144 | |
| Jack C. P. Cheng; Moumita Das | |||
| Collaboration technologies have been increasingly used for supporting the
requirements of a multi-disciplinary construction project team in recent years.
In particular, web services technology has been leveraged in the construction
industry for distributed communication and information management through
message exchanges. However, the current standardized web services are
unsuitable for typical construction information, which is large in magnitude
and diverse in scope. This paper presents our proposed context aware web
service framework that uses standardized ontologies to facilitate efficient and
faster exchange of construction information in real time. This paper also
presents an example scenario illustrating the collaborative environment
facilitated with the proposed web service framework. Keywords: Building information exchange; Construction Collaboration Technology;

| Visualization of the cooperation context is an important issue, especially
when applied to complex and unstable collective activities, as it is the case
in the field of Architecture, Engineering and Construction (AEC). With the aim

| An Augmented Reality Application Framework for Complex Equipment Collaborative Maintenance | | BIBAK | Full-Text | 154-161 | |
| Wei Wang; Yue Qi; QingXing Wang | |||
| Complex equipment maintenance process usually involves massive amount of
components. It requires collaborative manipulation by many technicians.
Therefore, traditional maintenance is difficult to meet the needs of these
processes. Augmented reality technology has been demonstrated as an useful
solution. This paper introduces an augmented reality application framework
applicable to various complex equipments. In the framework, the difference of
different equipments maintenance processes is extracted as task-driven work
flow, and the functional interfaces of augmented reality are the collective
base. We can create a new application as long as we can place the work flow and
associated virtual resources within the application. Context-aware tutorial
information and hands-free voice commands are provided in the generated
applications by the framework. By using the application, the multi-user
cooperative operations are well supported. We demonstrate our framework by
showing the applications for key aircraft components. We also present a
distributed virtual learning tool based on the framework. Keywords: Augmented Reality; Task-driven Work Flow; Collaborative Maintenance | |||

| In this paper a cooperative system for visualisation of a biotechnical
system is presented. Some of the events associated with the state of metabolic
reactions are indistinguishable, mainly due to lack of appropriate sensors and
measurement capabilities. Therefore, a solution is needed to identify the state
in which the reactor currently is, based on partial information and selected
measurements available in real time. Those partial identification results are
than used to provide a cumulative result by means of a voting mechanism between
the cooperating agents. Keywords: Voting; Multi-Agent Systems; Monitoring of Biotechnological Processes | |||
| Comparing Static Load Balancing Algorithms in Grid | | BIBAK | Full-Text | 170-177 | |
| Sherihan Abu Elenin; Masato Kitakami | |||
| The ability to monitor and manage Grid computing components is critical for
enabling high performance distributed computing. The Grid Monitoring
Architecture (GMA) specification sets out the requirements and constraints of
any implementation. There are many systems that implement GMA but all have some
drawbacks such as, difficult to install, single point of failure, or loss of
control message. So we design a simple model after we analyze the requirements
of Grid monitoring. We propose grid monitoring system based on GMA. The
proposed grid monitoring system consists of producers, registry, consumers, and
failover registry. The goals of it are the management and failure recovery.
Load balancing (LB) should be added to the system to overcome the message
overloaded. Load balancing algorithms can be static or dynamic. This paper
evaluates the four types of static load balancing algorithms. We evaluate the
performance of the system by measuring the response time, and throughput.
Central Manager algorithm introduces the smallest response time and the highest
throughput. So it is the best static load balancing algorithm. Keywords: Grid computing; Security; monitoring system; load balancing; response time;

| A Model for Collaborative Scheduling Based on Competencies | | BIBAK | Full-Text | 178-181 | |
| Tomasz Kajdanowicz | |||
| The paper presents a proposal for scheduling human resources among projects.
In the situation when multiple number of projects needs to be planned in an
organisation and only available human resources can be used for their
completion, a group of managers needs to align scheduling and work
collaboratively. The planning problem in such situations requires considering
appropriate employee assignment to tasks, according to their specific skills
and time constraints, which makes it very complicated. The paper describes a
proposal of a model that provides the staffing solution optimisation for the
given objective function, e.g. maximising the increase of competencies of the
staff. Modelling is based on the quantitative description of tasks and
employees. Keywords: collaborative scheduling; staff scheduling; competence scheduling model | |||

| Efficient System for Clustering of Dynamic Document Database | | BIBAK | Full-Text | 186-189 | |
| Pawel Foszner; Aleksandra Gruca; Andrzej Polanski | |||
| We describe in this paper, a system that groups, classifies and finds the
latent semantic features in a database composed of a large number of documents.
The database will be constantly growing as users who co-create it will be
adding more and more new documents. Users require a system to provide them
information, both about a specific document, and about the entire set of
documents. This information includes statistical data about words in documents,
information about aspects in which this words appears, classification,
clustering, etc.
To meet these expectations we propose using methods for searching for hidden patterns in multivariable data. We apply machine learning algorithms for data analysis, useful in identifying local patterns in multivariate data. We consider two different algorithms described in the literature (1) Probabilistic Latent Semantic Analysis Method [2] and (2) Nonnegative Matrix Factorization algorithm described in [4] and used in the text analysis system [1].
