Abstract

In relation to the beginning of Europeana, the need to reflect on the information retrieval systems that are being implemented in this type of resources is considered. Frequently, digital repositories, libraries and harvesters are not applying retrieval systems that can compete with a search engine like Google. The existing quality tools in the traditional documental resources are not being applied either.

Abstract

A collection of eight documents on primary education provides the example for presenting a new indexing system based on a structure of primary and secondary descriptors and illustrating its equivalence to Universal Decimal Classification. The article shows the advantages of this new system as an information retrieval system and describes its role in the indexing system and process. Another aim of this article is to describe an actual project using a postcoordinate indexing system based on nuclear ordering of the descriptors, as well as to define the system and software requirements for efficient operation of user search and information retrieval functions.

Abstract

This paper presents a new method for the design and validation of advanced driver assistance systems (ADASs). With vehicle hardware-in-the-loop (VEHIL) simulations, the development process, and more specifically the validation phase, of intelligent vehicles is carried out safer, cheaper, and is more manageable. In the VEHIL laboratory, a full-scale ADAS-equipped vehicle is set up in a hardware-in-the-loop simulation environment, where a chassis dynamometer is used to emulate the road interaction and robot vehicles to represent other traffic. In this controlled environment, the performance and dependability of an ADAS is tested to great accuracy and reliability. The working principle and the added value of VEHIL are demonstrated with test results of an adaptive cruise control and a forward collision warning system. On the basis of the 'V' diagram, the position of VEHIL in the development process of ADASs is illustrated.
