A functional approach for the study of the random walks in random sceneries (RWRS) is proposed. Under fairly general assumptions on the random walk and on the random scenery, functional limit theorems are proved. The method allows to study separately the convergence of the walk and of the scenery: on the one hand, a general criterion for the convergence of the local time of the walk is provided...

The current information marketplace for tourists is dominated by for-profit purveyors of information. Potential visitors must rely on experts-for-hire or search engine results in order to learn about a desired destination. In this paper, we introduce The Madeira Touch, a multimodal display installation rooted in the unique characteristics of Madeira, which allows users to explore the island by ...

Suppose that the vertices of the lattice Z are endowed with a random scenery, obtained by tossing a fair coin at each vertex. A random walker, starting from the origin, replaces the coins along its path by i.i.d. biased coins. For which walks and dimensions can the resulting scenery be distinguished from the original scenery? We find the answer for simple random walk, where it does not depend o...

An algorithm for simulating wind-ripples and moving sand is extended by the detection of fixed objects. This permits us simulation and animation of sand interacting with objects like houses, highways, cactuses, etc. Sand is accumulated on the windward side of an obstacle and the sand relocation and wind-ripples formation is diminished on the leeward side. The wind shadow depends on the object’s...

Consider a simple random walk on ℤ with coloring of ℤ. Look at the sequence first N steps taken in walk, together colors visited locations. We call this record. From record one can deduce interval that was visited, which is size approximately $$\sqrt $$ . This called scenery reconstruction. Now suppose an adversary may change δN entries obtained. What we from about now? In paper show it likely ...

As digital cameras have been used widely, a technology to extract features of character string areas from scenery (nature) image is required. However, it is very difficult to extract character string areas from a complex background of scenery image as compared wit,h a relatively simple background of documentary image. Human can extract of character string areas from scenery image having complex...

A remote view system is a system for the delivery and presentation of information such as video and audio to users in remote locations. Methods for the construction of virtual environments based on video information have been applied to remote view technology. When a system that supports remote viewing is applied to situations such as viewing scenery or engaging in collaborative work, it is use...

The 1101 km length of the Andalusian coast (Spain) was assessed for coastal scenery at 45 specific locations. Selected areas covered resort (3), urban (19), village (8), rural (10) and remote (5) bathing areas. Scenery was analyzed for physical and human parameters via 26 selected parameters. These parameters were obtained by interviews of 4500 people on European beaches. Each parameter was ass...
