Treatment of implant-associated infection is becoming more challenging, especially when?bacterial biofilms?form on the surface of implants. To address the challenge of biofilm infection, developing du...
Identification of Multiword Expressions by Combining Multiple Linguistic Information Sources
language Natural language
2015/9/14
We propose a framework for using multiple sources of linguistic information in the task of
identifying multiword expressions in natural language texts. We define various linguistically
motivat...
What is here called controlled natural language (CNL) has traditionally been given many
different names. Especially during the last four decades, a wide variety of such languages
have been designed....

Selective thermal emission in a useful range of energies from a material operating at high temperatures is required for effective solar thermophotovoltaic energy conversion.Three-dimensional metallic ...
Ultrahigh-contrast and large-bandwidth thermal rectification in near-field electromagnetic thermal transfer between nanoparticles
Ultrahigh-contrast large-bandwidth thermal electromagnetic thermal transfer between nanoparticles
2015/8/7
We exploit the unique properties of optical waves in nanophotonic structures to enhance the capabilities for active control of electromagnetic thermal transfer at nanoscale. We show that the near-@...
Integrating model knowledge into SVM classification – Fusing hyperspectral and laserscanning data by kernel composition
hyperspectral airborne laserscanning data fusion support vector machine
2014/6/5
Roof materials are important sources of pollutants within cities.
To monitor and quantify polluted roof runoff, a precise classification approach of various roof material classes is needed. Wit...
We propose a mechanism for photon mediated thermal rectification through vacuum relying only on the temperature dependence of electromagnetic resonances. We also propose an example implementatio...
Combining radiationless interference with evanescent field amplification
radiationless interference
2015/8/10
The conventional approach for radiationless interference exploits the interference of evanescent components for the purpose of deep-subwavelength focusing and image formation. As a result, deep subwav...
