We introduced a new approach, termed schema coordination, as an alternative to the well-known schema integration approach for processing cooperative queries in federated database systems. The schema coordination approach is based on the attribute correspondence matrix that links similar attributes in all component databases. In this paper, we compare the schema coordination approach with the sc...

The intractability in cooperative, decentralized control models is mainly due to prohibitive memory requirements in both optimal policies and value functions. The complexity analysis has emerged as the standard method to estimating the memory needed for solving a given computational problem, but complexity results may be somewhat limited. This paper introduces a general methodology— structural ...

The paper describes how the Technical University of British Columbia (TechBC) is using online and cooperative learning to improve the quality of education offered to its students. To explain how web technology is being used to enhance learning, we focus on a sophomore level course in signal processing. Students study presentations delivered on the Web, discuss problems using an asynchronous con...

This research analyses the cooperative learning process in three groups applying the case study technique in a virtual university asynchronous communication context. The exploratory study was performed within a subject taught at a Master in e-learning programme. Based on a review of the theory and the current status of research, we delineate the concept of virtual cooperative learning and the m...

In this paper, we analyze the differences of effects of a deposit insurance schemes on financial cooperative and joint stock banks risk taking. We develop a methodology which includes the specifics of the utility function for the financial cooperative and we compare the results to a similar profit maximizing joint stock bank. We find that the introduction of deposit insurance does in fact incre...

This study was done as a part of a larger research project where the interest was on exploring if and how gameplay design could give informative principles to the design of educational activities. The researchers conducted a series of studies trying to map game mechanics that had the special quality of being inclusive, i.e., playable by a diverse group of players. This specific study focused on...

This paper addresses research into the application of cooperative visual SLAM for utilization within UAVs. The research utilized a synthetic approach to examine a cooperative data fusing strategy for multiple UAVs equipped with stereo vision camera systems, where the collaborative estimation was implemented with an information filter and covariance intersection technique to investigate potentia...

Combined with the methodology of cooperative genetic algorithm, a cooperative interactive genetic algorithm based on a user’s preference is proposed in this paper in allusion to solve a user’s fatigue problem in interactive genetic algorithm. The method of picking up a user’s preference based on fitness of a building block, the storage format of a user’s preference based on a network database, ...

Intermolecular interactions of different configurations in the HOClO3···CO and HOClO3···H2O dyad and CO···HOClO3···H2O triad systems have been studied at MP2/6-311++G(2d,2p) computational level. Molecular geometries, binding energies, cooperative energies, many-body interaction energies, and Energy Decomposition Analysis (EDA) were eval...

Cooperative Control of a Network of Multi-Vehicle Unmanned Systems Elham Semsar-Kazerooni, Ph.D. Concordia Unviersity, 2009 Development of unmanned systems network is currently among one of the most important areas of activity and research with implications in variety of disciplines, such as communications, controls, and multi-vehicle systems. The main motivation for this interest can be traced...
