To obtain a unified framework for symmetric and asymmetric heterotic orbifold constructions we provide a systematic study of Narain compactifications orbifolded by finite order T -duality subgroups. We review the generalized vielbein that parametrizes the Narain moduli space (i.e. the metric, the B-field …

The topic of this research paper are four contemporary flute techniques: whistle sounds, multiphonics, tongue ram and jet whistle. I wanted to understand these techniques from a scientific point of view and see if this knowledge can then help me improve their execution. There have been few studies done …

In this paper, we show our vision on prescriptive analytics. Prescriptive analytics is a field of study in which the actions are determined that are required in order to achieve a particular goal. This is different from predictive analytics, where we only determine what will happen if we continue current …

In pre-treatment dose verification, low resolution detector systems are unable to identify shifts of individual leafs of high resolution multi leaf collimator (MLC) systems from detected changes in the dose deposition. The goal of this study was to introduce an alternative approach (the shutter technique) …

Abstract—A survey about radiation protection in pediatric radiology was conducted among 22 general and seven children’s hospitals in the Netherlands. Questions concerned, for example, child protocols used for CT, fluoroscopy and x-ray imaging, number of images and scans made, radiation doses and measures …

How can physics education be designed and enacted in such a way that it is in agreement with the Nature of Science (NOS) and fosters conceptual understanding in electricity? The results of the studies may have implications for practice. Teachers and teacher educators need to develop a balanced perspective …

This paper presents a mixed methods study in which 77 students and 3 teachers took part, that investigated the practice of Learning by Design (LBD). The study is part of a series of studies, funded by the Netherlands Organisation for Scientific Research (NWO), that aims to improve student learning, teaching …

Since March 2015 the Faculty of Technology, Innovation and Society (TIS) of The Hague University of Applied Sciences (THUAS) is a CDIO member with all its twelve programs: Mechanical Engineering, Engineering Management, Mechatronics, Electrical Engineering, Building Engineering, Civil Engineering, Climate …

The objective of this study was to introduce a new iterative method to reconstruct multi leaf collimator (MLC) positions based on low resolution ionization detector array measurements and to evaluate its error detection performance. The iterative reconstruction method consists of a fluence model, a detector …
