World guidelines for falls prevention and management for older adults: a global initiative

BACKGROUND: falls and fall-related injuries are common in older adults, have negative effects on functional independence and quality of life and are associated with increased morbidity, mortality and health related costs. Current guidelines are inconsistent, with no up-to-date, globally applicable ones present. OBJECTIVES: to create a set of...

Complex Field Mapping of Large Direct Detector Focal Plane Arrays

Complex field mapping is a powerful tool to characterize the optical performance of astronomical instruments, and has become the standard for characterizing heterodyne array cameras. Recently, an adaptation of the heterodyne beam mapping technique was demonstrated on a single pixel of a direct detector instrument. We present a novel...

3D Anthropometry In Ergonomic Product Design Education

The Faculty of Industrial Design Engineering of the Delft University of Technology offers a bachelor’s degree education programme and three master’s programmes. Our students are lectured in ergonomics and learn to design and conduct research in ergonomics. In this paper we describe the development of methods to realise ergonomic fit mapping...

Shoe design for older adults: Evidence from a systematic review on the elements of optimal footwear

Due to changes in foot morphology and the occurrence of foot deformities and foot pain with ageing, older people frequently wear ill-fitting shoes. This can lead to negative effects on comfort and mobility. A review of the literature was performed in Medline, Scopus and Embase with the aim (a) to evaluate the effects of shoes or shoe elements on...

Application of 3D scanning in design education

Three-dimensional scanning technologies have brought great opportunities in ergonomic and product design education as well as research. Not only the anthropometric size but also the shape and posture of the human, form of a product, or interactions between the human and product obtained based on the 3D scanning have been usefully applied in...

Effectieve prestatiesturing met data voor de brandveiligheidssector

Binnen publieke organisaties bestaat steeds meer aandacht voor prestatiesturing. Zowel om de uitgaven te rechtvaardigen als om de publieke dienstverlening te verbeteren. Door de explosieve toename van data om de maatschappij en de activiteiten van de overheid in kaart te brengen heeft deze ontwikkeling<br/>een extra impuls gekregen. Effectieve...

Strategic position model Geo-ICT function: Facing the challenge of organizational alignment

This paper focuses on organizational aspects and aims to explain the dynamic alignment between the development of the internal Geo-ICT function, including the corporate SDI, of an organization and the interest of this organization in an SDI. It is proposed that a better understanding of the topic of alignment provides an insight into the...

GeoPortalNetwork: More process catalyst than project

Phase locking of a 2.7 THz quantum cascade laser to a microwave reference

We demonstrate the phase locking of a 2.7 THz metal–metal waveguide quantum cascade laser (QCL) to an external microwave signal. The reference is the 15th harmonic, generated by a semiconductor superlattice nonlinear device, of a signal at 182 GHz, which itself is generated by a multiplier chain (x12) from a microwave synthesizer at ~15 GHz....

Full characterization and analysis of a terahertz heterodyne receiver based on a NbN hot electron bolometer

We present a complete experimental characterization of a quasioptical twin-slot antenna coupled small area (1.0×0.15??m2) NbN hot electron bolometer (HEB) mixer compatible with currently available solid state tunable local oscillator (LO) sources. The required LO power absorbed in the HEB is analyzed in detail and equals only 25?nW. Due to the...
