Dike monitoring is crucial for protection against flooding disasters, an especially important topic in low countries, such as the Netherlands where many regions are below sea level. Recently, there has been growing interest in extending traditional dike monitoring by means of a sensor network. This paper presents a case study of a set of pore...

Today's crises attract great attention on social media, from local and distant citizens as well as from news media. This study investigates the possibilities of real-time and automated analysis of Twitter messages during crises. The analysis was performed through application of an information extraction tool to nearly 97,000 tweets that were...

Objective: To examine whether the "Short QUestionnaire to ASsess Health-enhancing physical activity" (SQUASH) and the "Injuries and Physical Activity in the Netherlands" questionnaire ("Ongevallen en Bewegen in Nederland," OBiN) were valid in assessing adherence to physical activity (PA) guidelines. Study Design and Setting: Participants (N =...

The Tropospheric Monitoring Instrument (TROPOMI) is being developed for launch in 2014 on GMES Sentinel 5 Precursor satellite. Global Monitoring for Environment and Security (GMES) is a joint initiative of the European Community (EC) and of the European Space Agency (ESA). TROPOMI is a passive sun backscatter spectrograph using the ultraviolet...

Purpose: To review recently published studies on the reproducibility, validity, and feasibility of motion sensors used to assess physical activity in healthy children and adolescents (2-18 yr). Methods: On October 2004, a systematic literature search in PubMed, EMBASE, and PsycINFO was performed. This search has been updated on October 2007. In...

The Ozone Monitoring Instrument (OMI) on NASA's AURA satellite is one of the first instruments measuring an extensive set of daily air quality parameters from space. This anwers to a growing interest in obtaining space data for the air we breath next to the higher altitude air masses. OMI combines UV-Visible nadir viewing spectroscopy, small...

Several organizations in the Netherlands are cooperating to develop user requirements and instrument concepts in the line of SCIAMACHY and OMI but with an increased focus on measuring tropospheric constituents from space. The concepts use passive spectroscopy in dedicated wavelength sections in the range of 300 to 2400 nm and wide angle, non...

The Ozone Monitoring Instrument (OMI) is a Dutch-Finnish contribution to NASA's EOS-Chemistry satellite, which is due to be launched in December 2002. The aim of OMI is to contribute to climate monitoring and atmospheric chemistry research by providing daily global measurements of the total ozone column, ozone profile, NO2 column, other trace...
