A logical characterisation of SPARQL federation
(2014)
The paper provides a logical characterisation of distributed processing of SPARQL queries. The principal notion analysed is that of a distribution scheme; a pair consisting of an evaluation rule and a distribution function. ...
Large-eddy simulation of dense gas dispersion over a simplified urban area
(2017)
Dispersion of neutral and dense gas over a simplified urban area, comprising four cubes, has been investigated by the means of large-eddy simulations (LES). The results have been compared to wind tunnel experiments and ...
Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
(2015)
Behavioral response studies (BRSs) aim to enhance our understanding of the behavior changes made by animals in response to specific exposure levels of different stimuli, often presented in an increasing dosage. Here, we ...
Identification and quantification of lichenysin – a possible source of food poisoning
(2015)
Lichenysin produced by 53 different Bacillus licheniformis strains has been structurally examined with a qualitative liquid chromatography-tandem mass spectrometry (LC-MS/MS) method using quadrupole-time-of-flight mass ...
Completeness and Accuracy of a Wide-Area Maritime Situational Picture based on Automatic Ship Reporting Systems
(2015)
Automatic ship reporting systems (AIS – Automatic identification System, LRIT – Long Range Identification and Tracking, VMS – Vessel Monitoring System) today allow global tracking of ships. One way to display the results ...
Toward federated mission networking in the tactical domain
(2015)
NATO is currently working on the Federated Mission Networking (FMN) concept, which will become the foundation for establishing mission networks in the future. The realization of the FMN concept is described in the NATO FMN ...
Optical parametric oscillators with high pulse energy and beam quality
(2010)
A new method for obtaining high beam quality from high pulse energy optical parametric oscillators (OPOs) is demonstrated. By using different nonlinear crystals that have walk-off in orthogonal directions but are type 2 ...
Modeling of a back-illuminated HgCdTe MWIR avalanche photodiode with alloy gradients
(2015)
We present results from 2D Monte Carlo simulations of a mid-wave infrared (MWIR) back-illuminated planar n-on-p HgCdTe electron-initiated avalanche photodiode (e- APD). The main objective of this work has been to study the ...
Multiple-array passive acoustic source localization in shallow water
(2017)
This paper considers concurrent matched-field processing of data from multiple, spatially-separated acoustic arrays with application to towed-source data received on two bottom-moored horizontal line arrays from the SWellEx-96 ...
Robust Web Services in Heterogeneous Military Networks
(2010)
NATO Network Enabled Capability is firstand foremost about achieving better interactionbetween the different actors involved in militaryoperations. This implies more efficient exchangeof information. Consequently, the NATO ...
