Cyanobacterial blooms can be toxic to humans swimming in affected waters. According to the European Bathing Water Directive bathing waters should be closed during cyanobacterial blooms. In the Netherlands, cyanobacteria monitoring in all official bathing water locations is usually performed every two …

Sleeping is an important part of human life as multiple sleep restriction studies have shown. However, its function is not yet completely understood even though researchers have been performing sleep experiments for years. These experiments require sleep stage scoring, which as of this moment is done …

Reducing the use of pesticides by early visual detection of diseases in precision agriculture is important. Because of the color similarity between potato-plant diseases, narrow band hyper-spectral imaging is required. Payload constraints on unmanned aerial vehicles require reduc- tion of spectral bands. …

This paper describes experiments with a game device that was used for early detection of delays in motor skill development in primary school children. Children play a game by bi-manual manipulation of the device which continuously collects ac- celerometer data and game state data. Features of the data …

Precast concrete structures are preferred for facilities with large open areas due to easiness in construction. Such structures are typically composed of individual columns and long-span beams, and are quite flexible and of limited redundancy. In this paper, nonlinear dynamic analyses of a typical such …

Raman spectroscopy is an optical technique that is based on the inelastic scattering of light. It is non-invasive, fast, objective and easy to use. These traits make it an ideal tool for use in medical diagnosis. Melanoma is the deadliest form of skin cancer. Currently, melanomas are visually diagnosed …

This paper presents a study of sensor data from a person who developed Alzheimer’s disease during a 4-year monitoring period and who is monitored with simple ambient sensors in her home. Our aim is to find data analysis methods that reveal relevant changes in the sensor pattern that occur before the …

Achtergrond Contrast Enhanced Spectral Mammograph (CESM) (CESM) is een nieuwe techniek binnen de mammografie die door een Low Energy opname (LE) en een High Energy opname (HE) een gecombineerd beeld geeft waarop een eventuele tumor middels contrast aankleurt. CESM heeft bewezen superieur te zijn aan …

The purpose of this report is to assess the relevance of the measurement of the spectrally resolved distribution of radiation in tokamak boundary plasmas. This assessment is important and urgent in view of the recent ambition to design and construct a multi-camera configuration for hyper imaging spectroscopy1 …

Objective: Due to the multidimensional nature of resonance disorders, multivariate diagnostic assessment is advisable. The nasality severity index (NSI) is based on this point of view. Because of the influence of personal and environmental variables on the current NSI, this study aims to refine this …
