During the last decade many national and regional Land Cover/Land Use projects are implemented based on computer aided satellite
image interpretation. An essential procedure for the European CORINE ...
Clarifying Open Access:its implications for the research community (Letter)
open access Green OA Gold OA publishing models publishing reform self-archiving research funding
2015/7/29
A critique of the CERN proposal to convert particle physics journals from the user-institution-pays subscription model to an author-institution-pays model for the sake of Open Access (OA). OA can be a...
Blame smartphone alerts, constant connectivity and a deluge of media for our society’s sleep deprivation. But the root cause of why we get less sleep now than our ancestors did could come down to a mu...
SPATIAL BIG DATA ORGANIZATION, ACCESS AND VISUALIZATION WITH ESSG
Spatial big data Global Spatial Grid ESSG Spatial Infrastructure Visualization Mapping Internet/Web Cloud
2014/4/21
There are hundreds of spatial reference frame (SRF) being applied, and the great difference among SRFs has blocked the share of
global data on planet Earth. A conceptual spheroid of radius 12,800km a...

We present an analysis of the mid-infrared (MIR) colours of 165 70um-detected galaxies in the Shapley supercluster core (SSC) at z=0.048 using panoramic Spitzer/MIPS 24 and 70um imaging. While the bul...
Medium Access Control for Wireless Networks with Peer-to-Peer State Exchange
Medium Access Wireless Networks Peer-to-Peer State Exchange Information Theory
2011/8/31
Abstract: Distributed medium access control (MAC) protocols are proposed for wireless networks assuming that one-hop peers can periodically exchange a small amount of state information. Each station m...
Nearest Neighbour Decoding with Pilot-Assisted Channel Estimation for Fading Multiple-Access Channels
Pilot-Assisted Channel Estimation Fading Multiple-Access Channels Information Theory
2011/8/30
Abstract: We study a noncoherent multiple-input multiple-output (MIMO) fading multiple-access channel (MAC), where the transmitters and the receiver are aware of the statistics of the fading, but not ...
Abstract: MDS (maximum distance separable) array codes are widely used in storage systems due to their computationally efficient encoding and decoding procedures. An MDS code with r redundancy nodes c...
