Autonomous Driving Progressed by oneM2M: The Experience of the AUTOPILOT Project

The European Commission Horizon 2020 AUTOPILOT (AUTOmated driving Progressed by Internet Of Things) is aiming to exploit the IoT ecosystem to integrate connected cars and transform them in automated moving "objects". One of the key challenges encountered in the project is to ensure the interoperability of the different components and IoT...

Applying innovative IT modelling methods to low-level grid information for DSO operations

Distribution system operators will gather an increasing amount of electricity data from the lower level of the grid to be able to cope with several challenges, such as an increase of distributed, heterogeneous energy production, local storage, and electric vehicles. Most DSOs are not yet prepared for collecting, storing and processing these...

Improving the development of instructional software: Three building-block solutions to interrelate design and production

Currently, there is a focus on authentic tasks as the driving force for learning in integrated e-learning systems. This sets new criteria for instructional software, which should become much more flexible and allow for domain modeling and pedagogical modeling. A theoretical analysis and a survey (n = 37) amongst experienced developers show that...

Aerosol retrieval from OMI: Applications to the amazon bassin

We present the aerosol optical depth retrieved from OMI measurements using the multi-wavelengthm algorithm for two different environments: over Western Europe where the aerosols are weakly absorbing and over the Amazon basin where aerosol optical properties are governed by biomass burning. The results are evaluated by comparison with MODIS data....

Dual hydraulic behaviour of the Chalk in the Netherlands North Sea

Information on the sedimentary development, seismic stratigraphy and burial compaction of the Chalk Group in the Netherlands North Sea was combined with pressure data and basin modelling to investigate the hydraulic behaviour of the Chalk Group in the Central Graben and Schill Grund High. The preliminary results of this integrated study indicate...

Comparative evaluation of the performance of online databases in answering toxicology queries

An evaluation of toxicology information resources is reported, comparing commercial online databases specialized in-house database. A mixed qualitative/quantitative approach, using 10 test queries and detailed failure analysis was used. The main conclusions are: the in-house database is superior to any `general' database in recall and precision;...

Development and test of an evaluation protocol for heavy gas dispersion models

In order to improve the quality (i.e. fitness-for-purpose) of models used to describe the atmospheric dispersion of heavy gas, an evaluation methodology has been developed and tested through a small evaluation exercise. This activity was carried out by the Heavy Gas Dispersion Expert Group, which was set up by European Commission's Model...

Is freight traffic noise more annoying than passenger traffic noise?

In the Netherlands a new freight-only railway route, the "Betuweroute", is being planned to carry freight traffic from Rotterdam harbour east into Germany. Inhabitants of areas near the future route are concerned about noise and vibration, and question the relevance of current legislation for a "freight-only" line. An analysis of field surveys,...

Routine multiple imputation in statistical databases

This paper deals with problems concerning missing data in statistical databases. Multiple imputation is a statistically sound technique for handling incomplete data. Two problems should be addressed before the routine application of the technique becomes feasible. First, if imputations are to be appropriate for more than one statistical analysis...

The reactive-tree: a storage structure for a seamless, scaleless geographic database

This paper presents the first fully dynamic and reactive data structure. Reactive data structures are vector based structures tailored to the efficient storage and retrieval of geometric objects at different levels of detail. Geometric selections can be interleaved by insertions of new objects and by deletions of existing objects. The core of...

A reactive data structure for geographic information systems

We introduce a Reactive Data Structure, that is a spatial data structure with detail levels. The two properties, spatial organization and detail levels, are the basis for a Geographic Information System with a multi-scale database. A reactive data structure is a novel type of data structure catering to S. It is presented here as a modification...
