A dataspace system manages the large scale heterogeneous collection of data distributed over various data sources in different formats. It addresses the structured, semistructured, and unstructured data in coordinated manner without presuming the semantic integration among them. Therefore, the management of heterogeneous data in a dataspace system is a crucial challenge. This work introduces a ...

It is quite evident nowadays that designing a database is too complicated a task for a single database administrator (DBA). There is definitely a need for more succesful methodologies, supporting distribution of the design task among various designers (whether users or local DBAs). Cooperative design is used here to denote design techniques based upon coordinated activities of several partners....

Fundamental to the design of visual languages are the goals of facilitating communication between people and computers, and between people and other people. The Object Block Programming Environment (OBPE) is a visual design, programming, and simulation tool which emphasizes support for both human-human and human-computer communication. OBPE provides several features to support effective communi...

The Distributed Research Infrastructure for Hydro-Meteorological Study (DRIHMS) is a coordinated action co-funded by the European Commission. DRIHMS analyzes the main issues that arise when designing and setting up a pan-European Grid-based e-Infrastructure for research activities in the hydrologic and meteorological fields. The main outcome of the project is represented first by a set of Grid ...

This paper focuses on modeling and parameter estimation for the electrohydraulic actuation system of an articulated forestry machine. The linear graph method is implemented in deriving mathematical models of the swing, boom and stick subsystems. Actuation dynamics are subsequently integrated with manipulator dynamics to result in a complete machine model. Identification procedures employed in e...

In this paper we discuss artificial plan designing as a research field that deals with the development and use of computational models to support the generation of design descriptions in architecture and urban planning. We discuss some crucial methodological issues and we present a model for artificial design generation based on learning control methodologies. The design problem is defined as a...

This paper presents a systematic procedure for designing a wide-area centralized Continuous Time Model Predictive Controller (CTMPC) to improve the angular stability of a multi-machine power system. In this scheme, each generator is assumed to be provided with a local controller to damp out the local mode of oscillations and also employs a global signal from the centralized controller to damp o...

This paper focuses on the modeling, parameter estimation, and model validation in open and closed-loop of an experimental forestry machine manipulator. Symbolic Newton-Euler and linear graph methodologies are used in deriving mathematical models of the swing, boom and stick subsystems. Actuation dynamics are integrated with manipulator dynamics to result in a complete manipulator and actuation ...

This paper outlines the research conducted on the SEAS DTC AA011 project into learning cooperative decision strategies for Autonomous Vehicles (AVs). The paper presents a brief review of the technical challenges involved and existing approaches to designing cooperative decision strategies. An initial study is used to compare two of the candidate solutions: Probability Collectives (PC) and Coord...

Agent coordination and communication are important issues in designing decentralised agent systems, which are often modelled as flavours of Markov Decision Processes (MDPs). Because communication incurs an overhead, various scenarios for sparse agent communication have been developed. In these treatments, coordination is usually considered more important than making use of local information. We...
