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 ...

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 ...

Since broadband network connections are becoming ubiquitous, people expect access to multimedia content anywhere anytime. This new demand results in a need to create and develop new, powerful devices for multimedia consumption. The new devices, each having their set of network and terminal capabilities, allow transparent access to multimedia and therefore open the path to transparent mobility o...

Each month the editor of Newsline selects article on diagnostic, therapeutic, research, and practice issues from a range of international publications. Many selections come from outside the standard canon of nuclear medicine and radiology journals. Note that although we have divided the articles into diagnostic and therapeutic categories, these lines are increasingly blurred as nuclear medicine...

The predictive power of logistic regression, support vector machines and bootstrap-aggregated classification trees (bagging, double-bagging) is compared using misclassification error rates on independent test data sets. Based on a resampling approach that takes into account spatial autocorrelation, error rates for predicting “present” and “future” landslides are estimated within and outside the...

Background:  Despite the introduction of different techniques for meniscal repair, no single procedure is superior in all situations. The new method for meniscal repair named “ modified outside-in technique ” aims to achieve higher primary fixation strength by an alternative suture technique as well as avoid disadvantages of outside-in, inside-out, and all-inside suture procedures. Additionally...
