Road network analysis can require distance from points that are not on the network themselves. We study the algorithmic problem of connecting a point inside a face (region) of the road network to its boundary while minimizing the detour factor of that point to any point on the boundary of the face. We show that the optimal single connection (feed-link) can(More)
Road network data is often incomplete, making it hard to perform network analysis. This paper discusses the problem of extending partial road networks with reasonable links, using the concept of <i>dilation</i> (also known as <i>crow flight conversion coefficient</i>). To this end, we study how to connect a point (relevant location) inside a polygon (face(More)
PURPOSE The Netherlands is developing a set of national domain information models to support electronic information exchange and electronic patient records (EPR). These domain information models aim to support the development, adoption, implementation and maintenance of the EPR in Dutch healthcare practice. This article describes the modelling for a pilot(More)
AIMS An ICI-RS Think Tank in 2014 discussed and evaluated the evidence for adding video and EMG to urodynamics (UDS) in children and also highlighted evidence gaps, with the aim of recommending further clinical and research protocols. METHODS A systematic analysis of the relevant literature for both X-ray (video) studies and electromyography, in(More)
PURPOSE We present a consensus view of members of the International Children's Continence Society on the therapeutic intervention in congenital neuropatic bladder and bowel dysfunction in children. MATERIAL AND METHODS Discussions were held by a group of pediatric urologists and gastroenterologists appointed by the board. The following draft review(More)
OBJECTIVE To study the clinical and urodynamic parameters of children who developed bladder diverticula (BD) after ureteral reimplantation. MATERIALS AND METHODS We have reviewed records of 15 children who underwent ureteric reimplantation, possibly with diverticulectomy between January 1998 and October 2004, who postoperatively developed BD and compared(More)
