This paper develops and analyses a biomimetic learning controller for robots. This controller can simultaneously adapt reference trajectory, impedance and feedforward force to maintain stability and minimize the weighted summation of interaction force and performance errors. This controller was inspired from our studies of human motor behavior, especially the human motor control approach dealin...

At ASDEX Upgrade (AUG), a new compact solid-state detector has been installed to measure the energy spectrum of fast neutrals based on the principle described by Shinohara et al. [Rev. Sci. Instrum. 75, 3640 (2004)]. The diagnostic relies on the usual charge exchange of supra-thermal fast-ions with neutrals in the plasma. Therefore, the measured energy spectra directly correspond to those of co...

We propose a generic and computationally efficient framework within which input XML data can be transformed depending on environment descriptions (e.g., terminal capabilities) and rule descriptions (e.g., access policies). We adopt a hybrid approach; the transformation engine consists of XSLT and DOM processors. The input XML data is transformed by an XSLT instance that is adapted by a DOM prog...

Introduction of LTE (Long Term Evolution) brings enhanced quality for 3GPP multimedia services. The high throughput and low latency of LTE enable higher quality media coding than what is possible in UMTS. LTE-specific codecs have not yet been defined but work on them is ongoing in 3GPP. The LTE codecs are expected to improve the basic signal quality, but also to offer new capabilities such as e...

The Software Defined Radio (SDR) is a class of reprogrammable and reconfigurable radios which can be switched from one air-interface to another. It is generally employed in software, which can be easily realized on base-station side. On terminal-side, the configurability of the radio has to be maintained in hybrid architecture, consist of both software as well as hardware, due to computational ...

An “ideal” upper limb prosthesis should be perceived as part of the natural body by the amputee and should replicate sensory-motor capabilities of the amputated limb. However, such an ideal “cybernetic” prosthesis is still far from reality: current prosthetic hands are simple grippers with one or two degrees of freedom (DOF), which barely restore the capability of the thumbindex pinch. This pap...

The capabilities of human motor behavior build on the integration of multiple sensory modalities in goal representation and feedback processing. Here, we present a hierarchical neural network model of motor control to simulate these capabilities, based on the SURE REACH model. The model is able to integrate visual and proprioceptive goal representations, but, by now, relies only on propriocepti...

In African mormyrid fishes, evolutionary change in a sensory region of the brain established an ability to detect subtle variation in electric communication signals. In one lineage, this newfound perceptual ability triggered a dramatic increase in the rates of signal evolution and species diversification. This particular neural innovation is just one in a series of nested evolutionary novelties...

As the driving forces of technological change continue to increase exponentially as predicted by Moores’ law, we have been witnessing in the last years major breakthroughs in the fields of wireless and mobile communications as well as unprecedented proliferation of multimedia enabled devices and networks. These devices can consume remote multimedia contents by connecting wirelessly through diff...
