Kuhl’s native language magnet (NLM) theory of phonetic learning is examined in the light of an exemplar-based model. According to the NLM theory the perceptual space is partitioned into phonetic categories as a consequence of the magnet-like properties of the category’s best exemplar  the category’s prototype. The NLM theory predicts that the perceptual space is warped in the neighborhood of t...

Our previous work in computer-aided mammography has used scale orientation pixel signatures to provide a rich description of local structure. However, when treated as vectors for statistical classi cation, the Euclidean space they de ne has unsatisfactory metric properties. In this paper we describe a scheme that makes use of a previously described signature similarity measure to de ne a non-li...

An effort is underway to develop a prototype Proton Exchange Membrane (PEM) Fuel Cell breadboard system for fuhlre space applications. This prototype will be used to develop a comprehensive des ign basis for a space-rated PEM fuel cell powerplant. The prototype system includes reactant pressure regulators, ejector-based reactant pumps, a 4-kW fuel cell stack and cooling system, and a passive, m...

The building sector is the largest consumer of energy, but there are still major scientific challenges in this field. façade, being interface between exterior and interior space, plays a key role energy efficiency building. In context, paper focuses on ventilated bioclimatic wall for nearly zero-energy buildings (NZEB). aim study to investigate an experimental setup based hot box characterizati...

Conventional vector-based simulators for quantum computers are quite limited in the size of the quantum circuits they can handle, due to the worst-case exponential growth of even sparse representations of the full quantum state vector as a function of the number of quantum operations applied. However, this exponential-space requirement can be avoided by using general space-time tradeoffs long k...

This paper describes a prototype robot and the necessary path planning and control for space inspection applications. The robot is the rst generation of a freeying robotic camera that will assist astronauts in constructing and maintaining the Space Station. The robot will provide remote views to astronauts inside the Space Shuttle and future Space Station, and to ground controllers. The rst par...
