Purpose To present the implementation of a magnetic resonance imaging (MRI) pre-planning technique in multi-interstitial perineal and endocavitary gynecological brachytherapy. Material and methods We used a new fully MRI-compatible applicator that is capable to engage titanium needles, and an intrauterine tandem, developed in our department for the treatment of gynecological cervical cancer p...

We collected think-aloud, pre-test, post-test, and motivation data from 43 undergraduates to examine the impact of conceptual scaffolds on the fluctuation of certain motivation constructs and use of self-regulatory processes during learning with hypermedia. Participants were randomly assigned to either the No Scaffolding (NS) or Conceptual Scaffolding (CS) condition. During the experimental ses...

We describe a computational model for planning phrases like “more than a quarter” and “25.9 per cent” which describe proportions at different levels of precision. The model lays out the key choices in planning a numerical description, using formal definitions of mathematical form (e.g., the distinction between fractions and percentages) and roundness adapted from earlier studies. The task is mo...

The farmer requires detailed information on crop stress conditions in order to manage the crop growth. This information may be acquired by low granular satellite images to coarsely identify areas of interest within the field followed by ground measurements carried out by robotic surveying platforms for plant identification and segmentation. A novel concept for creating rational behaviors of sur...

A key characteristic of intelligence is the use of efficient problem-solving strategies when faced with unfamiliar tasks. Enabling machines to do autonomous problem-solving is thus a major milestone on the path to developing intelligent systems. Automated planning is a discipline in artificial intelligence research that studies this topic, specifically the process of automatically computing str...

Wayfinding in road networks is a hierarchical process. It involves a sequence of tasks, starting with route planning, continuing with the extraction of wayfinding instructions, and leading to the actual driving. From one task level to the next, the relevant road network becomes more detailed. How does the wayfinding process change? Building on a previous, informal hierarchical highway navigatio...
