Skilled use of tools requires us to learn an "input-output map" for the device, i.e., how our movements relate to the actions of the device. We used the paradigm of visuo-motor rotation to examine two questions about the plasticity of input-output maps: 1) does extensive practice on one mapping make it difficult to modify and/or to form a new input-output map and 2) once a map has been modified...

turbocharging an engine boosts its power by increasing the amount of input air. this task is accomplished by using the exhaust gas to power a turbine which is engaged with a compressor. the variable geometry turbocharger, vgt is a unique turbocharger that the diffuser vane angle can be changed over a wide range of positions. the mathematics of turbomachinery flow analysis is intensive and uses ...

in this paper, we present the results of a hierarchical slam/gps/ins/wlfp sensor fusion to be used in navigation system devices. due to low quality of the inertial sensors, even a short-term gps failure can lower the integrated navigation performance significantly. in addition, in gps denied environments, most navigation systems need a separate assisting resource, in order to increase the avail...

Problem statement: In this study we propose a method to improve the performance of Maximum A-Posteriori Probability Algorithm, which is used in turbo decoder. Previously the performance of turbo decoder is improved by means of scaling the channel reliability value. Approach: A modification in MAP algorithm proposed in this study, which achieves further improvement in forward error correction by...

The present study sought to explore the impact of story maps and audio podcasts as scaffolds on oral proficiency of Iranian EFL learners. The quasi-experimental study was launched with 36 EFL undergraduates in three groups by adopting a counterbalanced 3  3 Latin squared design. All participants were indiscriminately, but in a specified order, exposed to the three treatment conditions of story ...

Cortical map plasticity is believed to be a key substrate of perceptual and skill learning. In the current study, we quantified changes in perceptual ability after pairing tones with stimulation of the cholinergic nucleus basalis to induce auditory cortex map plasticity outside of a behavioral context. Our results provide evidence that cortical map plasticity can enhance perceptual learning. Ho...

In this paper, we evaluate three different subcategories of image matching algorithms. We consider hierarchical matching, wavelet-based localized correlation and multiresolution subregioning. The importance of this evaluation stems from the fact that these algorithms are all somehow based on a multiresolution scheme, but exhibit different performances when dealing with featureless image pairs, ...

Dimensionality reduction methods for visualization map the original high-dimensional data typically into two dimensions. Mapping preserves the important information of the data, and in order to be useful, fulfils the needs of a human observer. We have proposed a self-organizing map (SOM)based approach for visual surface inspection. The method provides the advantages of unsupervised learning and...
