VFAT3 is the last version of a family of multichannel trigger and tracking ASICs designed for the upgrade of the CMS experiment in the LHC. The chip has been developed to provide fast trigger information from the readout of gas particle detectors improving the resolution of the time measurement. The VFAT3 architecture comprises 128 analog channels, each one composed by a low noise and low power charge...
This field trial transmits 1.5Tb/s superchannel with 5b/s/Hz spectral efficiency over 875km of EDFA-amplified SMF, using six 250Gb/s real time elastic transponders featuring 1dB minimum Q margin over 48 hours. Channels are 50GHz spaced.
This volume presents the latest developments in the field of high temperature superconductivity. It focusses on microscope description, physical properties, and materials and applications. The talks presented have been extensively edited and updated in order to present a valuable resource not only for the advanced reader, but also for a larger readership seeking reviews of current problems in high...
Summary As a first step towards assessing Hg levels in a systematic approach in South Africa, representatives from the South African government, academia, research councils and key industries recently initiated a South African Mercury Assessment (SAMA) Programme (Leaner et al., 2006). The SAMA Programme has undertaken some limited Hg inventory development and monitoring studies in South Africa. The...
Neben der Elimination beeinflussbarer Risikofaktoren stellen heutzutage Thrombozytenaggregationshemmer, Nitrate, Betarezeptorenblocker und lang wirksame Calciumantagonisten, alleine oder in Kombination, die medikamentöse Therapie der Wahl in der Langzeit-Behandlung zur Prophylaxe von Angina-pectoris-Anfällen dar. Die Besserung der Befindlichkeit unter Nitraten ist für Fachgesellschaften (Arzneimittelkommission...
Interoperable identity management systems are prerequisite for novel user-centric services, which strongly rely on user identity attributes and security services. Future identity management systems will enable dynamic and automatic exchange of user identity attributes between services from different key-business areas, e.g. Internet, healthcare, e-government, e-banking, entertainment, etc. Moreover,...
Identity management has become an issue of central importance. It is relevant to service composition and provisioning in telecommunications and in computer systems, especially to their security, enrichment and customization. However, the plentitude of proprietary and open source identity management solutions causes interoperability problems as well as legal issues. This in turn slows down the pace...
The authors present architectures and parameters of Digital Terrestrial Television tuners in order to find the right model for coverage calculations in dense Single Frequency Networks.
Usefulness and possibilities of realization of new broadband indoor transmission systems in an unlicensed band near 60 GHz have been presented. The author has analyzed radio channel characteristics in 60 GHz band and properties of uniform linear arrays of antennas using the LMS adaptive algorithm. The author has developed and described a software package in Matlab environment, which is capable of...
