This paper presents a new framework for building continuous media applications in mobile computing environment. In mobile computing environment, network bandwidth and machine con gurations may be changed dramatically, and mobile applications should be adapted to various operational environments for being executed e ciently. In our framework, an application is partitioned into two pieces. One pi...

A common belief about decision making is that the more information we process the better our decisions. Increasingly, we rely on (mobile) information systems to filter, aggregate and present information in order to make it easier to process. With the rise of mobile IS the question arises how decision behavior differs compared to stationary settings. In this paper we analyze user actions in a re...

Effectively solving the problem of when and where to forage is critical for survival in many animal species. The task is further complicated when there are other agents, potentially competing for the same limited resources. Previous models of foraging consider agents either in isolation or in groups but without competition. Here, we present a novel Bayesian model for competitive foraging, Socia...

n≥0 where T denotes the shift on Ω. Conditioned on the particle having asymptotic mean velocity equal to any given ξ, we show that the empirical process of the environment Markov chain converges to a stationary process μ ξ under the averaged measure. When d ≥ 3 and ξ is sufficiently close to the typical velocity, we prove that averaged and quenched large deviations are equivalent and when condi...

The potential field method is widely used for autonomous mobile robot path planning due to its elegant mathematical analysis and simplicity. However, most researches have been focused on solving the motion planning problem in a stationary environment where both targets and obstacles are stationary. This paper proposes a new potential field method for motion planning of mobile robots in a dynami...

In this paper we propose a game-based virtual reality platform for evaluation of sonification techniques. We study the task of localization of stationary objects in virtual reality using auditory cues. We further explore sonification techniques and compare the performance in this task using the proposed platform. The virtual reality environment is developed using Unity3D (game engine) and an Oc...

The present paper defines diversity gain for stationary users. This deals in particular with gathering the received signal statistics over possible user positions and orientations in space rather than over time, and to define a meaningful diversity gain related to the cumulative improvement of the performances of the 1% users with the worst receiving conditions. The definition is used to evalua...
