We propose a new system for vision-based mobile robot navigation in an unmodeled environment. Simple , unobtrusive artiicial landmarks are used as navigation and localization aids. The landmark patterns are designed so that they can be reliably detected in real-time in images taken with the robot's camera over a wide range of viewing conngurations. The code(More)
The associative memory function of the brain is an active area of experimental and theoretical research. This thesis describes the construction of a model of cor-tical auto-associative memory. Conceptually, it is based on Hebb's cell assembly hypothesis. The quantitative description comes from a class of artiicial neural networks, ANN, with recurrent(More)
—The increasing development of large-scale offshore wind farms around the world has caused many new technical and economic challenges to emerge. The capital cost of the electrical network that supports a large offshore wind farm constitutes a significant proportion of the total cost of the wind farm. Thus, finding the optimal design of this electrical(More)
This paper deals with the limit behaviour of the solutions of quasi-linear equations of the form − div (a (x, x/ε h , Du h)) = f h on Ω with Dirichlet boundary conditions. The sequence (ε h) tends to 0 and the map a(x, y, ξ) is periodic in y, monotone in ξ and satisfies suitable continuity conditions. It is proved that u h → u weakly in H 1,2 0 (Ω), where u(More)
The concept of smart microgrid (SMG) is widely recognized as one of the most promising and enabling technologies for smart grids. In this context, the development of integrated and decentralized frameworks for executing complex control and monitoring applications is still in its infancy and needs to be researched. To address this issue, this paper(More)
In future long duration Mars exploration missions, network limitations and the lack of real-time communication capabilities will impact various aspects of space crew performance as well as behavioral health. Studies in ground-based analogs of Isolated and Confined Environments (ICE) such as Antarctica have identified sensory and social monotony as threats(More)
Controlled islanding, which splits the whole power system into islands, is an effective way of limiting blackouts during severe disturbances. Finding islanding solutions in real time is difficult because of the combinatorial explosion of the solution space occurs for large power system. This paper proposes a computationally efficient algorithm based on(More)
