Artificial test eyes have been developed for a multimodal ophthalmic imaging platform. The test eyes can be used for alignment of different imaging modalities and for fluorescence channel performance testing. Different scattering and absorption characteristics can be realized in the artificial retina.

We report on the realization and verification of quantum entanglement between a nitrogen-vacancy electron spin qubit and a telecom-band photonic qubit. First we generate entanglement between the spin qubit and a 637 nm photonic time-bin qubit, followed by photonic quantum frequency conversion that transfers the entanglement to a 1588 nm photon....

The use of nano-scale copper oxide (CuO) and basic copper carbonate (Cu2(OH)2CO3) in both ionic and micronized wood preservatives has raised concerns about the potential of these substances to cause adverse humans health effects. To address these concerns, we performed quantitative (probabilistic) human health risk assessment (HHRA) along the...

Torrefaction is a promising biomass upgrading technology as it makes biomass more coal alike and offers benefits in logistics and handling operations. Gasification is an attractive thermochemical conversion technology due to its flexibility in the product gas end-uses. Therefore, it is valuable to investigate whether additional benefits are...

From 2007 to 2011 the company BTG and the universities of Eindhoven, Twente and Delft performed research related to biomass gasification and ensuing gas cleaning. The work was co-ordinated by ECN and funded by grants from the Dutch EOS-LT programme. Research was performed by 5 PhD students and staff of the parties involved. Subjects covered were...

An ash deposition modelling study based on the experimental results presented in Part I of this report is presented using the Ash Deposition Predictor (ADP) developed and implemented jointly by TUDelft and ECN. The numerical simulations were performed to answer open questions related to the deposition phenomena for coal and biomass blends and to...

Dendritic cells are believed to play an essential role in regulating the balance between immunogenic and tolerogenic responses to mucosal Ags by controlling T cell differentiation and activation via costimulatory and coinhibitory signals. The CD28/CTLA-4-CD80/CD86 signaling pathway appears to be one of the most important regulators of T cell...

This chapter describes the usage of polarization features of visible light for automatic landmine detection. The first section gives an introduction to land-mine detection and the usage of camera systems. In section 2 detection concepts and methods that use polarization features are described. Section 3 describes how these detection concepts...

IR decoys can be an effective countermeasure against IR guided anti ship missiles. However, it's not so easy to determine how the decoys should be deployed to get maximum effectiveness. A limitation of trials is that results are obtained for the specific trial condition only. Software tools have been developed to solve these problems. One...

This paper describes the development and implementation of a low cost camera system that uses polarisation features of visible light for faster area reduction. The camera system will be mounted on a mechanical minefield area reduction asset, namely an AT mine roller of The HALO Trust. The automatic detection system will give an audible alarm in...

Currently no single sensor reaches the performance requirements for humanitarian landmine detection, Using sensor-fusion methods, multiple sensors can be combined for improved detection performance. This paper focuses on the feature-level fusion procedure for a sensor combination consisting of a polarimetric infrared imaging sensor developed by...

This paper gives a comparison of two vehicle-mounted infrared systems for landmine detection. The first system is a down-ward looking standard infrared camera using processing methods developed within the EU project LOTUS. The second system is using a forward-looking polarimetric infrared camera. Feature-based classification is used for this...

Polarimetric scattering models are developed to predict the detectability of surface-laid landmines. A specular polarimetric model works well only under the condition that there is either no sunlight or the sun is not close to the specular reflection direction. Moreover, this model does not give insight why certain man-made objects like...

Feature-level sensor fusion is the process where specific information (i.e. features) from objects detected by different sensors are combined and classified. This paper focuses on the feature-level fusion procedure for a sensor combination consisting of a polarimetric infrared (IR) imaging sensor and a GPR: a video impulse radar (VIR). The...
