Consuming omega-3 fatty acids — particularly alpha-linolenic acid (ALA), a nutrient found in foods including flaxseeds, walnuts, and chia, canola, and soybean oils — may help slow the progression of d...
CELL COMPLEXES TOPOLOGICAL LINKS FOR BUILDINGS IN CITYGML
CityGML 3D Topology 3D City Model
2018/11/9
Topology has served as the foundation for analysis in modelling cities and buildings. CityGML as an international standard for 3D city modelling utilises a simple ‘topology-incidence’ which links conn...
Infrared links could simplify data center communications
Infrared links simplify data center communications
2017/2/16
Data centers are the central point of many, if not most, information systems today, but the masses of wires interconnecting the servers and piled high on racks begins to resemble last year's tangled C...
An Efficient Solution to Locate Sparsely Congested Links
Efficient Solution Locate Sparsely Congested Links
2016/1/22
Locating individual congested links in large scale networks is an important but difficult problem, because of the hardness to directly measure the massive links. Current advantages of network tomograp...
Scintillations effects on satellite to Earth links for telecommunication and navigation purposes
telecommunication navigation purposes
2015/9/14
Radio wave scintillations are rapid fluctuations in both amplitude and phase of signals propagating through the atmosphere. GPS signals can be affected by these disturbances which can lead to a comple...
THE POWER OF THE LINKS
image understanding knowledge representation modeling nets semantics
2015/1/23
“Knowledge” is a very useful metaphor in cognitive semantics and image understanding. The developed procedures in this field are mostly conveyed by a single methodology neglecting the benefits of syne...
Average Consensus in Wireless Sensor Networks with Probabilistic Network Links
Networks Sensor Wireless Consensus Average
2015/1/20
This study proposes and evaluates an average consensus scheme for wireless sensor networks. For this purpose, two communication error models, the fading signal error model and approximated fading sign...
The University of Queensland Academic Board President Professor Kaye Basford met Chinese President Xi Jinping in Beijing on 3 June.

New revolutionary sensor links pressure color change
2014/5/13
RIVERSIDE, Calif. — Imagine an automobile crash test that uses test dummies painted all over with a substance that can change color according to the levels of stress that various parts of the dummies’...
Performance of Optical Fast-OFDM in MMF-Based Links
Fiber optics communications Modulation
2015/5/26
19.375Gb/s optical Fast-OFDM signals can be transmitted over 500m worst-case MMF DML-based links having 3-dB effective bandwidths of 150MHz.km. This performance is similar to that corresponding to a c...
Symmetrical 2-D Hermite-Gaussian Square Launch for High Bit Rate Transmission in Multimode Fiber Links
Fiber optics communication Fiber properties
2015/5/26
A 2-D Hermite-Gaussian square launch is demonstrated to show improved systems capacity over multimode fiber links. It shows a bandwidth improvement over both center and offset launches and exhibits ±5...
We report error-free performance at 25Gb/s using a directly-modulated 850nm VCSEL over 100m graded-index perfluorinated plastic optical fiber with good launch offset tolerance.Bandwidth assessment of ...

Fiber optics links subsystems Fiber optics sources detectors Optical interconnects
2015/5/25
We report several firsts for CMOS-driven, VCSEL-based, multimode transmitters and receivers: serial links up to 20 Gb/s; unprecedented full-link power efficiencies from 8 pJ/bit (15 Gb/s) to 17 pJ/bit...
System Impacts of Modulation Technology and Phase Noise on Coherent Analog Optical Links
Radio frequency photonics
2015/5/22
We describe an analog optical link using amplitude modulation and coherent detection for high SFDR, gain, and low noise figure. We then address the dominant performance-limiting parameters and discuss...
