In this paper we present a new tool called BeanWatcher that allows the semi-automatic generation of multimedia monitoring and management applications for wireless sensor networks. Thus, particularities of multimedia management and wireless sensor networks were taken into account. The architecture of the tool is based on a component model flexible enough to allow the creation of new components a...

The second edition of the contest on Multi-Agent Systems based on computational logic was held in conjunction with the CLIMA ’06 workshop in Hakodate, Japan. Based on the experiences from the first edition of this contest ([8]), we decided to improve the setting of the first edition. In particular, we built a server to simulate the multi-agent system environment in which the agents from differe...

This artifact presents The Gamma, a simple programming environment for data exploration that uses member access as the primary mechanism for constructing queries. The artifact consists of two parts. The user facing web-based component allows users to explore a simple dataset of Olympic medal winners while a back-end service provides the data and evaluates queries executed by the user. The purpo...

We present JAPE, a flexible prototyping system to support the design of a new advanced collaborative virtual environment. We describe the utilization of different hardand software components to quickly build a flexible, yet powerful test bed for application and algorithm development. These components include a 3-D rendering toolkit, live video acquisition, speech transmission, and the control o...

This chapter discusses the design of modern numerical linear alge

Within the last few years navigation systems have started to conquer the market in the Western World. Especially in outdoor environments location based services play an important role for supporting the wayfinding process. Car drivers have started to trust in the information provided by car navigation systems and even pedestrians are gaining interest in reliable guiding instructions. Neverthele...

We present an agent-based model of a minimal economy containing households, retail banks, and producers of consumer and capital goods. Household behavior is based on the buffer-stock savings model by Deaton (1961), while the profit-maximizing firms employ reinforcement learning to determine pricing and production. Competitive retail banks facilitate the flow of funds between households and prod...

In this paper, Focus is on texture as primary feature. Shape and spatial information were secondary features. Texture features derived from nine grid sizes of independent and different Gabor filter banks were incorporated into the CBIR system by taking advantage of the fact that each grid size of filter is suited to capture particular set of localized frequency-images in diverse database. This ...

Collaborative Working Environments (CWEs) are getting prominence these days. With the increase in the use of collaboration tools and technologies, a lot of sharing and privacy issues have also emerged. Due to its dynamic nature, a CWE needs to adapt the changes into accordingly. In this paper, we have implemented the Adaptive Dynamic Sharing and Privacy-aware Role Based Access Control (Adaptive...

Wireless sensor networks (WSNs) enable smart environments to provide pervasive and ubiquitous applications, which give contextaware and scalable services to the end users. In this paper, an agent-based architecture is proposed for knowledge discovery and the variation in received signal strength indicator (RSSI) is used for knowledge extraction. Several experiments are conducted in an in-door e...
