Embodied conversational agents (ECAs) are computer-generated, human-like characters that interact with human users in face-to-face conversations. ECA is a powerful tool for representing cultural differences and is suitable for interactive training or edutainment systems. This article presents preliminary results from the development of a culture-adaptive virtual tour guide agent for serving Japanese, Croatian, and general Western users by displaying appropriate verbal and non-verbal behaviors. It is being implemented in Generic ECA Framework, a modular framework for developing ECAs. Dividing the ECA functions into reusable and loosely coupled modules minimizes the effort required to implement additional behavior and facilitates incremental scale up of the system. © Springer-Verlag London Limited 2009.

In recent years, computer-generated interactive virtual characters, called Embodied Conversational Agents (ECAs), are subjects of considerable ongoing research. Nevertheless, their conversational abilities are mediocre compared to real human behaviors. Among limitations, most of ECAs are incapable of participating in natural conversations in which the number of participants can change dynamically. In the ongoing work we investigate principles of integrating a multi-user support in an ECA system. We present experiments and implementation approach of a prototype system in which a tour guide ECA interacts with one or two users. The system combines different technologies to detect and address the system users and draw their attention. Experimental interaction with the system produces encouraging results. The system can address the user's appearance, departure, decreased level of interest and identify his conversational role. © 2009 Springer-Verlag.

This paper proposes novel techniques for the improvement of the convergence characteristic of step-by-step time integrations in nonlinear transient eddy-current analyses. The proposed methods, which are based on the time-periodic finite-element method and the explicit error correction method, can extract poorly-converged error components corresponding to large time constants of an analyzed system. The correction of the extracted error components accelerates the convergence of transient calculation efficiently. Furthermore, we extend the performance of the proposed methods in nonlinear problems. Some numerical results that verify the effectiveness of the proposed methods are also presented. © 2009 The Institute of electrical Engineers of Japan.

One of the most critical reason that prevents embodied conversational agents to be used in practical applications can be considered as the lack of the capabilities to be aware of multiple users and to interact with them. This paper presents our investigations in an advanced tour guide agent system serving two users and a simpler quiz agent kiosk which is developed for public exhibitions. To improve the life likeness of the agents, we propose that the agent should be attentive to its users. To achieve the agent's attentiveness toward the users, two aspects are considered: its utterance strategy toward the users and its internal attitude should be adaptive to users' status. To explore these two aspects more throughly, two prototype systems are implemented and evaluated with subject experiments respectively. In addition to regular questionnaires evaluation, GNAT test that measures implicit preference was conducted as well. The preliminary results implied that the experiment participants perceived that the agents are attentive and natural.

Embodied Conversational Agents (EGAs) are life-like computer generated characters that interact with human users in face-to-face multi-modal conversations. ECA systems are generally complex and difficult for individual research groups to develop. Therefore, if there was a common framework for connecting ECA functioning blocks seamlessly to an integrated system, redundant effort can be saved. This paper discusses the issues emerged in developing such a framework and introduces the design and preliminary results of our ongoing project, Generic ECA Framework.

In the design process of a reconfigurable accelerator employing in an embedded system, multitude parameters may result in remarkable complexity and a large design space. Design space exploration as an alternative to the quantitative approach can be employed to find a right balance between the different design parameters. In this paper, a hybrid approach is introduced to analytically explore the design space for a coarse grain accelerator and determine a wise design point exploiting data extracted from applications, quantitatively. It also provides flexibility for taking into account new design constraints as well as new characteristics of applications. Furthermore, this approach is a methodological approach which reduces the design time and results in a point which satisfies the design goals. ©2008 IEEE.

The advancement of traffic makes world more and more internationalized and increases frequency of communication between people who come from different cultures. Differences in their conversation go beyond the languages they speak to the non-verbal behaviors they express while talking. To improve the abilities of the embodied conversational agents (ECAs) while interacting with human users we are working on the ECA based application, a tour guide of city Dubrovnik that servers visitors in Japanese, Croatian and general western cultures speaking in English. This paper presents the overall architecture and explains possible extension with another culture. It describes issues we met while making agent talk in Croatian and proposed solutions.

The Generation Challenge programme (GCP) is a global crop research consortium directed toward crop improvement through the application of comparative biology and genetic resources characterization to plant breeding. A key consortium research activity is the development of a GCP crop bioinformatics platform to support GCP research. This platform includes the following: (i) shared, public platform-independent domain models, ontology, and data formats to enable interoperability of data and analysis flows within the platform;(ii) web service and registry technologies to identify, share, and integrate information across diverse, globally dispersed data sources, as well as to access high-performance computational (HPC) facilities for computationally intensive, high-throughput analyses of project data;(iii) platform-specific middleware reference implementations of the domain model integrating a suite of public (largely open-access/-source) databases and software tools into a workbench to facilitate biodiversity analysis, comparative analysis of crop genomic data, and plant breeding decision making.

This paper proposes a supervised version of a learning algorithm for a constructive neuro-immune network. The proposed methodology is developed by taking ideas from the immune system and learning vector quantization. The resulting classification algorithm is characterized by high-performance, similar to the ones produced by alternative methods in the literature, and parsimonious solutions, with a much smaller set of prototypes per class when compared with the other approaches. The number of prototypes is automatically defined by the convergence criterion. The algorithm requires a single user-defined parameter for training, associated with the convergence criterion, and the computational cost is sufficiently reduced to support applications involving large data sets.
