Multimedia is gaining ever more importance on the Internet. This increases the need for intelligent and efficient video caches. A promising approach to improve caching efficiency is to adapt videos. With the availability of MPEG-4 it is possible to develop a standard compliant proxy cache that allows fast and efficient adaptation. We propose a modular design for an adaptive MPEG-4 video proxy t...

Active sensing organisms, such as bats, dolphins, and weakly electric fish, generate a 3-D space for active sensation by emitting self-generated energy into the environment. For a weakly electric fish, we demonstrate that the electrosensory space for prey detection has an unusual, omnidirectional shape. We compare this sensory volume with the animal's motor volume--the volume swept out by the b...

Audio-motor integration is currently viewed as a predictive process in which the brain simulates upcoming sounds based on voluntary actions. This perspective does not consider how our auditory environment may trigger involuntary action absence of prediction. We address this issue by examining relationship between acoustic salience and motor responses. investigate features music contribute to pe...

The experience of modern warfare and the results scientific research show that an important most effective means solving tasks special physical training military personnel is use exercises sports, which are closest in terms movements used nature exertion to their professional activities. One these applied all-around and, above all, pentathlon. Taking it allows you adequately develop necessary q...

Learning is a fundamental component of intelligence, and a key consideration in designing cognitive architectures such as Soar [Laird et al., 1986]. This chapter considers the question of what constitutes an appropriate general-purpose learning mechanism. We are interested in mechanisms that might explain and reproduce the rich variety of learning capabilities of humans, ranging from learning p...

To be able to generate desired movements a robot needs to learn which motor commands move the limb from one position to another. We argue that learning by imitation might be an efficient way to acquire such a function, and investigate favorable properties of the movement used during training in order to maximize the control system’s generalization capabilities. Our control system was trained to...

Nanostructured materials are a new class of materials which provide one of the greatest potentials for improving performance and extended capabilities of products in a number of industrial sectors, including the aerospace, tooling, automotive, electronic, recording, cosmetics, electric motor, duplication, and refrigeration industries. Encompassed by this class of materials are multilayers, nano...

We propose an integrated model of the saccadic circuitry involved in target selection and motor command. It includes the Superior Colliculus and the Basal Ganglia in both cortical and subcortical loops. This model has spatial and feature-based learning capabilities which are demonstrated on various saccade tasks on a robotic platform. Results show that it is possible to learn to select saccades...

according to the resource based attitude, the capabilities of information systems improve firms’ performance and competitive advantages through three ways: 1) inside-outside capabilities, 2) outside-inside capabilities and 3) spanning capabilities. because of the importance of systematic study on the relationship between these capabilities and firms’ performance this paper was aimed at investig...

One trend in Human Computer Interaction is to extend the sensory-motor capabilities of computer systems to better match the natural communication means of humans. Parallel to the exploratory development of such systems, significant effort is being deployed in defining frameworks and taxonomies for reasoning about the design space of such systems. This article is a preliminary effort to review c...
