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...

Recent years have seen a proliferation in the use of wireless multi-hop networks in diverse scenarios ranging from community mesh networks to wireless sensor networks. As wireless networks find application in such wide-ranging arenas and are deployed at large scale, they will increasingly need to operate in the presence of heterogeneous, and often constrained, hardware capabilities. Furthermore...

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 ...

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...

The first neutron spectrometer of ASDEX Upgrade (AUG) was installed in November 2008. It is a compact neutron spectrometer (CNS) based on a BC501A liquid scintillating detector, which can simultaneously measure 2.45-MeV and 14-MeV neutrons emitted from deuterium (D) plasmas and γ radiation. The scintillating detector is coupled to a digital pulse shape discrimination data acquisition (DPSD) sys...

With the advent of the new wireless technologies allowing for higher data rates, the provision of high quality multimedia services over the upcoming wireless and mobile networks is gaining momentum. These future mobile networks are witnessed to consist of a variety of heterogeneous wireless access technologies connected to a high-speed IP datagram-based core network. The heterogeneity of these ...
